Definitions

  • the invention relates to a construction element comprising a securing device intended to secure a construction accessory to a beam, said construction element comprising a concrete body and at least said beam extending into the concrete body.
  • the creation of a floor consists, for example, of installing a set of beams supporting on shear walls or beams of the building, so as to cover the entire surface of the floor to be created, then install spacers between the joists.
  • US 3,920,221 A discloses a construction element comprising a concrete body and a device for securing a construction accessory.
  • An aim of the invention is to propose an element construction comprising a securing device.
  • the invention makes it possible to pinch the beam ensuring good fixing of the invention to the beam. This makes it possible in particular to avoid a disconnection or a tilting of the invention.
  • the invention is simple to construct and inexpensive to produce.
  • the invention is very simple to install on site.
  • a guardrail can thus be associated with the invention and easily and easily secure a construction site.

  • the two jaws 7, 8 and the tab 9 are preferably shaped into a rider, the jaws 7, 8 forming the wings of said rider and the tab 9 its central portion.
  • the first jaw 7 is shaped into a blade.
  • the first jaw 7 extends for example in a single plane when the clamp is in the rest state (i.e. it does not undergo external action).
  • the first jaw 7 is fixed to the sheath 3 so that the first axis X is parallel to said plane in which the first jaw 7 extends.

De la sorte, l'invention permet de venir pincer la poutrelle assurant une bonne fixation de l'invention à la poutrelle. Ceci permet notamment d'éviter un décrochement ou un basculement de l'invention.In this way, the invention makes it possible to pinch the beam ensuring good fixing of the invention to the beam. This makes it possible in particular to avoid a disconnection or a tilting of the invention.

En outre, l'invention est simple de construction et peu coûteuse à produire.Furthermore, the invention is simple to construct and inexpensive to produce.

Par ailleurs l'invention est très simple à installer sur chantier.Furthermore, the invention is very simple to install on site.

Un garde-corps peut ainsi être associé à l'invention et sécuriser aisément et facilement un chantier. Optionnellement, les moyens d'accueil comportent un fourreau servant en service de plot d'ancrage à l'accessoire de construction.A guardrail can thus be associated with the invention and easily and easily secure a construction site. Optionally, the reception means include a sheath serving as an anchoring pad for the construction accessory.

Optionnellement, les moyens d'accueil comportent au moins un bouchon pour boucher l'une des extrémités des moyens d'accueil.Optionally, the reception means include at least one plug to block one of the ends of the reception means.

Les opérateurs n'ont qu'à introduire ledit accessoire de construction dans les moyens d'accueil pour solidariser l'accessoire à l'élément de construction ce qui est rapide et aisé.If the construction element is a prefabricated construction element, the element is therefore delivered to the site directly incorporating the means of receiving the construction accessory. Operators only have to introduce said construction accessory into the reception means to secure the accessory to the construction element, which is quick and easy.

Si l'élément de construction n'est pas un élément de construction préfabriqué, il s'avère toujours très simple pour un opérateur de solidariser le dispositif de solidarisation à la poutrelle avant de couler le corps en béton sur l'ensemble permettant de solidariser le dispositif au corps en béton. Là encore l'invention propose une solution rapide et aisée.If the building element is not a prefabricated building element, it still turns out to be very simple for an operator to secure the securing device to the beam before pouring the concrete body onto the assembly allowing the device to be secured to the concrete body. Here again the invention offers a quick and easy solution.

Optionnellement l'élément de construction est un plancher.Optionally the construction element is a floor.

Pour toute la présente demande, les termes « inférieur », « supérieur », « hauteur », « longueur » ... doivent être entendus par rapport à la position en service du dispositif soit la position du dispositif une fois fixé à la poutrelle.For the entire present application, the terms “lower”, “upper”, “height”, “length” etc. must be understood in relation to the position in service of the device, i.e. the position of the device once fixed to the beam.

D'autres caractéristiques et avantages de l'invention ressortiront à la lecture de la description qui suit de modes de réalisation particuliers non limitatifs de l'invention.Other characteristics and advantages of the invention will emerge on reading the following description of particular non-limiting embodiments of the invention.

DESCRIPTION DETAILLEE DE L'INVENTIONDETAILED DESCRIPTION OF THE INVENTION

Un dispositif de solidarisation selon un premier mode de réalisation particulier de l'invention est illustré à la figure 1.A securing device according to a first particular embodiment of the invention is illustrated in the figure 1 .

Ce dispositif, généralement désigné en 1, est ici dédié à la solidarisation d'un accessoire de construction à un élément de construction. L'accessoire de construction peut être de tout type comme un élément de coffrage, un élément de sécurité tel qu'un garde-corps, un élément d'isolation thermique ...This device, generally designated 1, is here dedicated to securing a construction accessory to a construction element. The construction accessory can be of any type such as a formwork element, a safety element such as a guardrail, a thermal insulation element, etc.

Le dispositif 1 comporte des moyens d'accueil 2 de l'accessoire de construction.The device 1 comprises means 2 for receiving the construction accessory.

Lesdits moyens d'accueil 2 comportent ici au moins un plot d'ancrage de l'accessoire de construction. Le plot d'ancrage est ici conformé sous la forme d'un fourreau 3. Le fourreau 3 est par exemple en métal.Said reception means 2 here comprise at least one anchoring stud of the construction accessory. The anchoring stud is here shaped in the form of a sheath 3. The sheath 3 is for example made of metal.

Le fourreau 3 est ici conformé de sorte à s'étendre selon un premier axe X. Le fourreau 3 est conformé en un solide de révolution. Le fourreau 3 est ici conformé extérieurement en un cylindre droit de génératrice le premier axe X.The sheath 3 is here shaped so as to extend along a first axis X. The sheath 3 is shaped like a solid of revolution. The sheath 3 is here shaped externally into a straight cylinder generating the first axis X.

Dans le cas présent, le fourreau 3 est creux. Ainsi une section radiale du fourreau 3 est de forme annulaire.In the present case, the sheath 3 is hollow. Thus a radial section of the sheath 3 is of annular shape.

De préférence les moyens d'accueil 2 comportent au moins un premier bouchon 5 pour boucher (temporairement ou de manière permanente) l'extrémité inférieure des moyens d'accueil 2.Preferably the reception means 2 comprise at least a first plug 5 to block (temporarily or permanently) the lower end of the reception means 2.

Le premier bouchon 5 comble ainsi l'extrémité inférieure du fourreau 3.The first plug 5 thus fills the lower end of the sheath 3.

Ceci évite que du béton ne remonte dans le fourreau 3 lors de la coulée du béton formant un corps en béton de l'élément de construction ce qui pourrait gêner la solidarisation ultérieure de l'accessoire de construction audit élément.This prevents concrete from rising into the sheath 3 during the pouring of concrete, forming a concrete body of the construction element, which could hinder the subsequent attachment of the construction accessory to said element.

De préférence les moyens d'accueil 2 comportent au moins un deuxième bouchon 4 pour boucher temporairement l'extrémité haute des moyens d'accueil 2.Preferably the reception means 2 comprise at least a second plug 4 to temporarily block the upper end of the reception means 2.

Le deuxième bouchon 4 comble ainsi temporairement l'extrémité supérieure du fourreau 3.The second plug 4 thus temporarily fills the upper end of the sheath 3.

Ceci évite une obstruction accidentelle du fourreau 3 (par la pluie, le gel, du béton ...) qui pourrait gêner la solidarisation ultérieure de l'accessoire de construction à l'élément de construction.This avoids accidental obstruction of the sheath 3 (by rain, frost, concrete, etc.) which could hinder the subsequent attachment of the construction accessory to the construction element.

Bien entendu le deuxième bouchon 4 est conformé pour pouvoir être retiré à tout moment afin de permettre la solidarisation de l'accessoire de construction à l'élément de construction. Le deuxième bouchon 4 est de préférence conformé pour pouvoir être retiré manuellement sans utilisation d'un outil. Par exemple le deuxième bouchon 4 est simplement emboité dans le fourreau 3 ou clipsé au fourreau 3.Of course the second plug 4 is shaped so that it can be removed at any time in order to allow the construction accessory to be joined to the construction element. The second plug 4 is preferably shaped so that it can be removed manually without using a tool. For example, the second cap 4 is simply fitted into the sheath 3 or clipped to the sheath 3.

Par ailleurs, le dispositif 1 comporte des moyens d'accroche 6 des moyens d'accueil 2 à au moins une poutrelle.Furthermore, the device 1 comprises means 6 for attaching the receiving means 2 to at least one beam.

Lesdits moyens d'accroche 6 comportent au moins une pince d'accroche. Ladite pince d'accroche est ici conformée pour être fixée à une tête de poutrelle P.Said hooking means 6 comprise at least one hooking clip. Said hanging clip is here shaped to be fixed to a beam head P.

La pince d'accroche est fixée aux moyens d'accueil 2 par exemple par soudage, par collage ...The hanging clip is fixed to the reception means 2 for example by welding, by gluing, etc.

Ladite pince d'accroche comprend un premier mors 7 et un deuxième mors 8 mobiles l'un par rapport à l'autre.Said hanging clamp comprises a first jaw 7 and a second jaw 8 movable relative to each other.

De préférence seul le premier mors 7 est fixé aux moyens d'accueil 2 par exemple par soudage, par collage ... Le premier mors 7 est ainsi immobile vis-à-vis des moyens d'accueil 2.Preferably only the first jaw 7 is fixed to the receiving means 2 for example by welding, by gluing, etc. The first jaw 7 is thus immobile with respect to the receiving means 2.

Le deuxième mors 8 est monté mobile sur le premier mors 7 par une patte 9 élastiquement déformable.The second jaw 8 is movably mounted on the first jaw 7 by an elastically deformable tab 9.

Typiquement la patte 9 est dans un matériau pour ressort.Typically the tab 9 is made of a spring material.

Ainsi il est possible de modifier la position relative entre le premier mors 7 et le deuxième mors 8 grâce à ladite patte 9.Thus it is possible to modify the relative position between the first jaw 7 and the second jaw 8 thanks to said tab 9.

Selon un mode de réalisation préféré, au moins l'un des mors est également en matériau élastiquement déformable. De préférence encore, les deux mors 7, 8 sont en matériau élastiquement déformable.According to a preferred embodiment, at least one of the jaws is also made of elastically deformable material. More preferably, the two jaws 7, 8 are made of elastically deformable material.

Ici toute la pince d'accroche est en matériau élastiquement déformable.Here the entire hanging clip is made of elastically deformable material.

Que l'on considère la patte 9 et/ou le premier mors 7 et/ou le deuxième mors 8 et/ou toute la pince, le matériau élastiquement déformable est par exemple en un matériau pour ressort à lame. Dans le cas présent, le matériau élastiquement déformable est par exemple en acier tel que de l'acier mangano-siliceux.Whether we consider the tab 9 and/or the first jaw 7 and/or the second jaw 8 and/or the entire clamp, the elastically deformable material is for example made of a material for a leaf spring. In the present case, the elastically deformable material is for example steel such as manganese-siliceous steel.

La pince est de préférence d'une seule pièce. Ainsi la patte 9 et les deux mors 7, 8 sont venues de matière.The clamp is preferably made in one piece. Thus the tab 9 and the two jaws 7, 8 came from material.

Les deux mors 7, 8 et la patte 9 sont de préférence conformés en un cavalier, les mors 7, 8 formant les ailes dudit cavalier et la patte 9 sa portion centrale. Optionnellement, le premier mors 7 est conformé en une lame. Le premier mors 7 s'étend par exemple dans un unique plan lorsque la pince est à l'état de repos (i.e. elle ne subit pas d'action extérieure). Le premier mors 7 est fixé au fourreau 3 de sorte que le premier axe X soit parallèle audit plan dans lequel s'étend le premier mors 7. Optionnellement, la patte 9 est conformée en une lame. La patte 9 s'étend par exemple dans un unique plan à l'état de repos de la pince. La patte 9 s'étend par exemple orthogonalement au premier mors 7.The two jaws 7, 8 and the tab 9 are preferably shaped into a rider, the jaws 7, 8 forming the wings of said rider and the tab 9 its central portion. Optionally, the first jaw 7 is shaped into a blade. The first jaw 7 extends for example in a single plane when the clamp is in the rest state (i.e. it does not undergo external action). The first jaw 7 is fixed to the sheath 3 so that the first axis X is parallel to said plane in which the first jaw 7 extends. Optionally, the tab 9 is shaped like a blade. The tab 9 extends for example in a single plane in the rest state of the clamp. The tab 9 extends for example orthogonally to the first jaw 7.

Optionnellement, le deuxième mors 8 est conformé en une lame. Ici, au moins l'extrémité d'attache du deuxième mors 8 à la patte 9 ainsi que sa portion centrale s'étendent dans un premier plan à l'état de repos de la pince. Ce premier plan est parallèle au plan unique dans lequel s'étend le premier mors 7 dans l'état de repos de la pince. De préférence, l'extrémité libre du deuxième mors 8 (soit celle opposée à l'extrémité d'attache) s'étend dans un deuxième plan différent du premier plan dans lequel s'étend le reste du deuxième mors 8 lorsque la pince est à l'état de repos. Le deuxième plan est ici incliné vis-à-vis du premier plan.Optionally, the second jaw 8 is shaped into a blade. Here, at least the attachment end of the second jaw 8 to the tab 9 as well as its central portion extend in a first plane in the rest state of the pliers. This first plane is parallel to the single plane in which the first jaw 7 extends in the rest state of the pliers. Preferably, the free end of the second jaw 8 (i.e. that opposite the attachment end) extends in a second plane different from the first plane in which the rest of the second jaw 8 extends when the pliers are at the state of rest. The second plane is here inclined towards the first plane.

L'extrémité libre forme ainsi un rabat 10 du deuxième mors 8. Le rabat 10 est orthogonal ou incliné vis-à-vis du reste du deuxième mors 8. Dans le cas présent, le rabat 10 est incliné vis-à-vis du reste du deuxième mors 8. De préférence, le rabat 10 s'étend vers l'intérieur de la pince. Le rabat 10 s'étend ici en direction d'une face inférieure de la patte 9.The free end thus forms a flap 10 of the second jaw 8. The flap 10 is orthogonal or inclined with respect to the rest of the second jaw 8. In the present case, the flap 10 is inclined with respect to the rest of the second jaw 8. Preferably, the flap 10 extends towards the inside of the pliers. The flap 10 extends here towards a lower face of the tab 9.

En service, le dispositif 1 qui vient d'être décrit est implanté directement sur un chantier une fois au moins une poutrelle posée. Le dispositif 1 est implanté de préférence une fois les différentes poutrelles posées et des entrevous agencés entre les poutrelles.In service, the device 1 which has just been described is installed directly on a construction site once at least one beam has been installed. Device 1 is preferably installed once the different beams have been installed and spaces arranged between the beams.

Pour fixer le dispositif 1, le dispositif 1 est placé au-dessus de la tête d'une des poutrelles P en place. Le deuxième mors 8 est décalé du premier mors 7 afin que le dispositif 1 puisse venir autour de la tête de poutrelle P, celle-ci étant ainsi logée à l'intérieur de l'espace délimité par le cavalier.To fix device 1, device 1 is placed above the head of one of the beams P in place. The second jaw 8 is offset from the first jaw 7 so that the device 1 can come around the beam head P, the latter thus being housed inside the space delimited by the rider.

Le deuxième mors 8 est ensuite relâché ce qui permet à la pince d'enserrer la tête de poutrelle P assurant la fixation du dispositif 1 à la poutrelle P.The second jaw 8 is then released which allows the pliers to grip the head of the beam P ensuring the fixing of the device 1 to the beam P.

Dans cette position le fourreau 3 s'étend le long de la tête de poutrelle. Dans cette position le fourreau 3 s'étend à la verticale.In this position the sheath 3 extends along the head of the beam. In this position the sheath 3 extends vertically.

De la sorte, on solidarise facilement et rapidement le dispositif 1 à la poutrelle P. En outre, le dispositif 1 peut s'adapter à des profils différents de poutrelles.In this way, the device 1 is easily and quickly joined to the beam P. In addition, the device 1 can adapt to different beam profiles.

De manière avantageuse, le rabat 10 repose sous la semelle supérieure de la poutrelle P, préférentiellement au niveau de la jonction entre la semelle supérieure et l'âme de la poutrelle P. Ceci renforce la solidarisation du dispositif à la poutrelle P.Advantageously, the flap 10 rests under the upper flange of the beam P, preferably at the level of the junction between the upper flange and the web of the beam P. This reinforces the connection of the device to the beam P.

On retient par ailleurs que le premier mors 7 est ici fixe vis-à-vis de la poutrelle P : c'est le deuxième mors 8 seulement qui se déplace vis-à-vis du premier mors pour assurer la fixation du dispositif 1 à la poutrelle P.We also note that the first jaw 7 is here fixed with respect to the beam P: it is only the second jaw 8 which moves with respect to the first jaw to ensure the fixing of the device 1 to the beam P.

Le béton est ensuite coulé pour former la dalle de compression du plancher une fois des armatures, de type treillis soudés, posées sur chantier (avant et/ou après la fixation du dispositif à la poutrelle).The concrete is then poured to form the compression slab of the floor once the reinforcements, such as welded mesh, have been installed on site (before and/or after fixing the device to the beam).

Une fois que le béton a été coulé et a terminé de prendre, le dispositif 1 se retrouve rigidement solidarisé au corps de la dalle de compression de sorte à former avec le plancher un tout-rigide.Once the concrete has been poured and has finished setting, the device 1 finds itself rigidly attached to the body of the compression slab so as to form an all-rigid structure with the floor.

Ainsi le dispositif 1 est rigidement solidarisé au corps de la dalle de compression du plancher en étant ancré dans celui-ci. Seuls les moyens d'accueil 2 dépassent au moins en partie de la face supérieure de la dalle de compression pour permettre à un opérateur de solidariser un ou des accessoires de construction au plancher en construction. De la sorte, on solidarise facilement et rapidement le dispositif 1 au plancher en cours de construction.Thus the device 1 is rigidly secured to the body of the floor compression slab by being anchored therein. Only the reception means 2 protrude at least partly from the upper face of the compression slab to allow an operator to secure one or more construction accessories to the floor under construction. In this way, the device 1 is easily and quickly secured to the floor during construction.

Un dispositif de solidarisation selon un deuxième mode de réalisation particulier de l'invention est illustré à la figure 2.A securing device according to a second particular embodiment of the invention is illustrated in the figure 2 .

Ce dispositif, généralement désigné en 101, est ici dédié à la solidarisation d'un accessoire de construction à un élément de construction. L'accessoire de construction peut être de tout type comme un élément de coffrage, un élément de sécurité tel qu'un garde-corps, un élément d'isolation thermique ...This device, generally designated 101, is here dedicated to securing a construction accessory to a construction element. The construction accessory can be of any type such as a formwork element, a safety element such as a guardrail, a thermal insulation element, etc.

Le dispositif 101 comporte des moyens d'accueil 102 de l'accessoire de construction.The device 101 includes means 102 for receiving the construction accessory.

Lesdits moyens d'accueil 102 comportent ici au moins un plot d'ancrage de l'accessoire de construction. Le plot d'ancrage est ici conformé sous la forme d'un fourreau 103. Le fourreau 103 est par exemple en métal.Said reception means 102 here comprise at least one anchoring stud of the construction accessory. The anchoring stud is here shaped in the form of a sheath 103. The sheath 103 is for example made of metal.

Le fourreau 103 est ici conformé de sorte à s'étendre selon un premier axe X. Le fourreau 103 est conformé en un solide de révolution. Le fourreau 103 est ici conformé extérieurement en un cylindre droit de génératrice le premier axe X.The sheath 103 is here shaped so as to extend along a first axis X. The sheath 103 is shaped like a solid of revolution. The sheath 103 is here shaped externally into a straight cylinder generating the first axis X.

Dans le cas présent, le fourreau 103 est creux. Ainsi une section radiale du fourreau 103 est de forme annulaire. De préférence les moyens d'accueil 102 comportent au moins un premier bouchon pour boucher (temporairement ou de manière permanente) l'extrémité inférieure des moyens d'accueil 102.In the present case, the sheath 103 is hollow. Thus a radial section of the sheath 103 is of annular shape. Preferably the reception means 102 comprise at least a first plug to block (temporarily or permanently) the lower end of the reception means 102.

Le premier bouchon comble ainsi l'extrémité inférieure du fourreau 103.The first plug thus fills the lower end of the sheath 103.

Ceci évite que du béton ne remonte dans le fourreau 103 lors de la coulée du béton formant un corps en béton de l'élément de construction ce qui pourrait gêner la solidarisation ultérieure de l'accessoire de construction audit élément.This prevents concrete from rising into the sheath 103 during the pouring of concrete forming a concrete body of the construction element, which could hinder the subsequent attachment of the construction accessory to said element.

De préférence les moyens d'accueil 102 comportent au moins un deuxième bouchon 104 pour boucher temporairement l'extrémité haute des moyens d'accueil 102.Preferably the reception means 102 comprise at least a second plug 104 to temporarily block the upper end of the reception means 102.

Le deuxième bouchon 104 comble ainsi temporairement l'extrémité supérieure du fourreau 103.The second plug 104 thus temporarily fills the upper end of the sheath 103.

Ceci évite une obstruction accidentelle du fourreau 103 (par la pluie, le gel, du béton ...) qui pourrait gêner la solidarisation ultérieure de l'accessoire de construction à l'élément de construction.This avoids accidental obstruction of the sheath 103 (by rain, frost, concrete, etc.) which could hinder the subsequent attachment of the construction accessory to the construction element.

Bien entendu le deuxième bouchon 104 est conformé pour pouvoir être retiré à tout moment afin de permettre la solidarisation de l'accessoire de construction à l'élément de construction. Le deuxième bouchon 104 est de préférence conformé pour pouvoir être retiré manuellement sans utilisation d'un outil. Par exemple le deuxième bouchon 104 est simplement emboité dans le fourreau 103 ou clipsé au fourreau 103.Of course the second plug 104 is shaped so that it can be removed at any time in order to allow the securing the construction accessory to the construction element. The second plug 104 is preferably shaped so that it can be removed manually without using a tool. For example, the second cap 104 is simply fitted into the sheath 103 or clipped to the sheath 103.

Par ailleurs, le dispositif 101 comporte des moyens d'accroche 6 des moyens d'accueil 102 à au moins une poutrelle P.Furthermore, the device 101 comprises means 6 for attaching the receiving means 102 to at least one beam P.

Lesdits moyens d'accroche 106 comportent au moins une pince d'accroche.Said hooking means 106 comprise at least one hooking clip.

Ladite pince d'accroche est ici conformée pour être fixée à une tête de poutrelle P.Said hanging clip is here shaped to be fixed to a beam head P.

La pince d'accroche est fixée aux moyens d'accueil 102 par exemple par soudage, par collage ...The hanging clip is fixed to the receiving means 102 for example by welding, by gluing, etc.

Ladite pince d'accroche comprend un premier mors 107 et un deuxième mors 108 mobiles l'un par rapport à l'autre.Said hooking clip comprises a first jaw 107 and a second jaw 108 movable relative to each other.

Optionnellement la pince d'accroche comporte une platine 110 à laquelle est fixée le premier mors 107 de sorte que la platine 110 et le premier mors 107 sont immobiles l'un par rapport à l'autre. Le premier mors 107 est par exemple d'une seule pièce avec la platine 110.Optionally the hanging clamp comprises a plate 110 to which the first jaw 107 is fixed so that the plate 110 and the first jaw 107 are stationary relative to each other. The first jaw 107 is for example made in one piece with the plate 110.

La platine 110 s'étend rectilignement dans un plan sensiblement horizontal.The plate 110 extends rectilinearly in a substantially horizontal plane.

Le premier mors 107 s'étend à partir de l'une des côtés latéraux de la platine 110 à partir de la face inférieure de celle-ci.The first jaw 107 extends from one of the lateral sides of the plate 110 from the lower face thereof.

Le premier mors 107 est ici conformé en un crochet. A cet effet, l'extrémité libre du premier mors 107 (opposée à celle rattachant le premier mors 107 à la platine 110) forme un rabat du premier mors 107. De préférence, le rabat s'étend vers l'intérieur de la pince. Le rabat s'étend ici en direction de la face inférieure de la platine 110. Préférentiellement le premier mors 107 est conformé de sorte à épouser la forme de la tête de poutrelle P que le premier mors 107 encadrera à terme.The first jaw 107 is here shaped like a hook. For this purpose, the free end of the first jaw 107 (opposite to that attaching the first jaw 107 to the plate 110) forms a flap of the first jaw 107. Preferably, the flap extends towards the inside of the pliers. The flap extends here towards the underside of the plate 110. Preferably the first jaw 107 is shaped so as to match the shape of the beam head P which the first jaw 107 will ultimately frame.

A cet effet, le premier mors 107 est conformé de sorte que sa surface interne (i.e. sa surface tournée vers l'intérieur de la pince et destinée à venir en regard de la tête de poutrelle P) comporte :

  • une zone plane destinée à venir reposer contre l'une des faces latérales de la semelle de la poutrelle P,
  • le rabat destinée à venir reposer contre l'une des faces latérales de l'âme de la poutrelle P, le rabat formant également une zone plane, et
  • une zone de jonction s'étendant de manière inclinée entre la zone plane et le rabat selon une inclinaison identique ou similaire à la zone de jonction entre l'âme et la semelle de la poutrelle P, la zone de jonction du premier mors 107 étant destiné à venir reposer contre la zone de jonction correspondante de la tête de poutrelle P.
For this purpose, the first jaw 107 is shaped so that its internal surface (ie its surface facing the inside of the clamp and intended to come opposite the head of the beam P) comprises:
  • a flat zone intended to rest against one of the lateral faces of the sole of the beam P,
  • the flap intended to rest against one of the lateral faces of the web of the beam P, the flap also forming a flat zone, and
  • a junction zone extending in an inclined manner between the flat zone and the flap at an inclination identical or similar to the junction zone between the core and the sole of the beam P, the junction zone of the first jaw 107 being intended to come to rest against the corresponding junction zone of the beam head P.

Optionnellement seule la platine 110 est fixée aux moyens d'accueil par exemple par soudage, par collage ... Ainsi le premier mors 107 comme la platine 110 sont immobiles vis-à-vis des moyens d'accueil 102.Optionally only the plate 110 is fixed to the receiving means for example by welding, by gluing, etc. Thus the first jaw 107 like the plate 110 are immobile with respect to the receiving means 102.

Par exemple les moyens d'accueil 102 sont agencés dans la platine 110 du même côté latéral que le premier mors 107 mais à niveau de la face supérieure de la platine 110. Comme pour le premier mode de réalisation, les moyens d'accueil 102 sont donc agencés au niveau du premier mors 107 i.e. au niveau du mors fixe.For example, the receiving means 102 are arranged in the plate 110 on the same lateral side as the first jaw 107 but level with the upper face of the plate 110. As for the first embodiment, the receiving means 102 are therefore arranged at the level of the first jaw 107 i.e. at the level of the fixed jaw.

Par ailleurs, au niveau de son deuxième côté latéral, la platine 110 comporte au moins un passage à travers lequel peut se déplacer le deuxième mors 108 relativement au premier mors 107. Par exemple le deuxième mors 108 se déplace vis-à-vis du premier mors 107 par coulissement. Par exemple le passage consiste en un rail de coulissement du deuxième mors 108.Furthermore, at its second lateral side, the plate 110 has at least one passage through which the second jaw 108 can move relative to the first jaw 107. For example the second jaw 108 moves relative to the first jaws 107 by sliding. For example, the passage consists of a sliding rail of the second jaw 108.

Le deuxième mors 108 comporte ici une embase conformée pour coulisser dans ledit rail, embase prolongée par un crochet. A cet effet, l'extrémité libre du crochet (opposée à celle rattachant le crochet à l'embase) forme un rabat du deuxième mors 108. De préférence, le rabat s'étend vers l'intérieur de la pince. Le rabat s'étend ici en direction de la face inférieure de la platine 110. Préférentiellement le deuxième mors 108 est conformé de sorte à épouser la forme de la tête de poutrelle P que le deuxième mors 108 encadrera à terme.The second jaw 108 here comprises a base shaped to slide in said rail, base extended by a hook. For this purpose, the free end of the hook (opposite to that attaching the hook to the base) forms a flap of the second jaw 108. Preferably, the flap extends towards the inside of the pliers. The flap extends here towards the lower face of the plate 110. Preferably the second jaw 108 is shaped so as to match the shape of the beam head P which the second jaw 108 will ultimately frame.

A cet effet, le deuxième mors 108 est conformé de sorte que sa surface interne (i.e. sa surface tournée vers l'intérieur de la pince et destinée à venir en regard de la tête de poutrelle P) comporte :

  • une zone plane destinée à venir reposer contre l'autre des faces latérales de la semelle de la poutrelle P,
  • le rabat destiné à venir reposer contre l'autre des faces latérales de l'âme de la poutrelle P, le rabat formant également une zone plane, et
  • une zone de jonction s'étendant de manière inclinée entre la zone plane et le rabat selon une inclinaison identique ou similaire à la zone de jonction entre l'âme et la semelle de la poutrelle P, la zone de jonction du deuxième mors 108 étant destinée à venir reposer contre la zone de jonction correspondante de la tête de poutrelle P.
For this purpose, the second jaw 108 is shaped so that its internal surface (ie its surface facing the inside of the clamp and intended to come opposite the head of the beam P) comprises:
  • a flat zone intended to rest against the other of the lateral faces of the sole of the beam P,
  • the flap intended to rest against the other of the lateral faces of the web of the beam P, the flap also forming a flat zone, and
  • a junction zone extending in an inclined manner between the flat zone and the flap at an inclination identical or similar to the junction zone between the core and the sole of the beam P, the junction zone of the second jaw 108 being intended to come to rest against the corresponding junction zone of the beam head P.

De préférence, la platine 110 comporte plusieurs passages et l'on peut ainsi venir agencer l'embase dans l'un ou l'autre des passages selon la distance que l'on souhaite avoir entre les deux mors. Préférentiellement, on peut venir coulisser l'embase dans chacun desdites passages. De préférence, les différents rails de chaque passage sont parallèles entre eux. Par exemple au moins l'un des rails s'étend dans un plan incliné vis-à-vis d'un plan vertical et/ou au moins un des rails s'étend dans un plan droit vis-à-vis d'un plan vertical.Preferably, the plate 110 has several passages and the base can thus be arranged in one or the other of the passages depending on the distance that one wishes to have between the two jaws. Preferably, the base can be slid into each of said passages. Preferably, the different rails of each passage are parallels between them. For example at least one of the rails extends in an inclined plane with respect to a vertical plane and/or at least one of the rails extends in a straight plane with respect to a plane vertical.

Ainsi il est possible de modifier la position relative entre le premier mors 107 et le deuxième mors 108 au moins par déplacement de l'embase dans l'un des passages et optionnellement en associant l'embase à des passages différents de la platine 110.Thus it is possible to modify the relative position between the first jaw 107 and the second jaw 108 at least by moving the base in one of the passages and optionally by associating the base with different passages of the plate 110.

Les deux mors 107, 108 et la platine 110 forment ainsi un cavalier, les mors formant les ailes dudit cavalier et la platine sa portion centrale.The two jaws 107, 108 and the plate 110 thus form a rider, the jaws forming the wings of said rider and the plate its central portion.

Optionnellement, au moins l'un des mors 107, 108 et/ou la platine 110 est en métal. Alternativement au moins l'un des mors 107, 108 et/ou la platine 110 est en plastique. Dans le cas présent les deux mors 107, 108 et la platine 110 sont en métal.Optionally, at least one of the jaws 107, 108 and/or the plate 110 is made of metal. Alternatively at least one of the jaws 107, 108 and/or the plate 110 is made of plastic. In the present case the two jaws 107, 108 and the plate 110 are made of metal.

On retient que le deuxième mors 108 forme ici une pièce indépendante de la platine 110.We note that the second jaw 108 here forms an independent part of the plate 110.

De manière particulière, le dispositif 101 peut en outre comporter un verrou 111 pour maintenir en position le deuxième mors 108 dans la platine 110. Le verrou 111 peut par exemple être une pièce additionnelle venant s'insérer entre l'embase et la platine 110 et/ou entre l'embase et la poutrelle P.In particular, the device 101 can also include a lock 111 to hold the second jaw 108 in position in the plate 110. The lock 111 can for example be an additional part inserted between the base and the plate 110 and /or between the base and the beam P.

Le verrou 111 est par exemple conformé en un bloc présentant deux faces inclinées l'une par rapport à l'autre de sorte à former conjointement une pointe apte à venir s'insérer entre l'embase et la platine 110 et/ou entre l'embase et la tête de poutrelle P.The lock 111 is for example shaped into a block having two faces inclined relative to each other so as to jointly form a point capable of being inserted between the base and the plate 110 and/or between the base and joist head P.

En service, le dispositif 1 qui vient d'être décrit est implanté directement sur un chantier une fois au moins une poutrelle P posée. Le dispositif 1 est implanté de préférence une fois les différentes poutrelles posées et des entrevous agencés entre les poutrelles.In service, the device 1 which has just been described is installed directly on a construction site once at least one beam P has been installed. Device 1 is preferably installed once the different beams have been installed and spaces arranged between the beams.

Pour fixer le dispositif 1, le dispositif 1 est placé au-dessus de la tête d'une des poutrelles P en place de sorte que la face inférieure de la platine 110 repose au moins en partie sur la semelle supérieure de ladite poutrelle P et de sorte que le premier mors 107 épouse au moins en partie le côté de ladite poutrelle P.To fix the device 1, the device 1 is placed above the head of one of the beams P in place so that the lower face of the plate 110 rests at least partly on the upper flange of said beam P and so that the first jaw 107 matches at least partly the side of said beam P.

Dans cette position, l'embase du deuxième mors 108 est coulissée dans l'un des rails de la platine jusqu'à ce que le deuxième mors 108 vienne en contact avec ladite poutrelle P.In this position, the base of the second jaw 108 is slid into one of the rails of the plate until the second jaw 108 comes into contact with said beam P.

Le verrou 111, et plus particulièrement sa pointe, est ensuite placé entre la platine 110 et l'embase ou entre l'embase et la poutrelle P pour maintenir le deuxième mors 108 en position vis-à-vis de la platine 110 et de la poutrelle P. Optionnellement, un marteau peut être utilisé pour enfoncer davantage la pointe dans le dispositif 101. Dans cette position la tête de poutrelle P est enserrée dans le cavalier.The lock 111, and more particularly its tip, is then placed between the plate 110 and the base or between the base and the beam P to maintain the second jaw 108 in position vis-à-vis the plate 110 and the beam P. Optionally, a hammer can be used to further drive the point into the device 101. In this position the head of the beam P is clamped in the jumper.

Dans cette position le fourreau 103 s'étend sur le côté de la tête de poutrelle P. Dans cette position le fourreau 103 s'étend à la verticale.In this position the sheath 103 extends on the side of the beam head P. In this position the sheath 103 extends vertically.

De la sorte, on solidarise facilement et rapidement le dispositif 101 à la poutrelle P. En outre, le dispositif 101 peut s'adapter à des profils différents de poutrelles. De manière avantageuse, le cavalier épouse la forme de la tête de la poutrelle P (grâce à la conformation particulière des mors) ce qui renforce la solidarisation du dispositif 101 à la poutrelle P.In this way, the device 101 is easily and quickly joined to the beam P. In addition, the device 101 can adapt to different beam profiles. Advantageously, the rider follows the shape of the head of the beam P (thanks to the particular conformation of the jaws) which reinforces the attachment of the device 101 to the beam P.

En particulier, les rabats viennent en appui contre l'âme ce qui renforce la solidarisation du dispositif 101 à la poutrelle P.In particular, the flaps come to rest against the core, which reinforces the connection of the device 101 to the beam P.

On retient par ailleurs que le premier mors 107 est ici fixe vis-à-vis de la poutrelle P : c'est le deuxième mors 108 seulement qui se déplace vis-à-vis du premier mors 107 pour assurer la fixation du dispositif 101 à la poutrelle P.We also note that the first jaw 107 is here fixed with respect to the beam P: it is only the second jaw 108 which moves with respect to the first jaw 107 to ensure the fixing of the device 101 to the beam P.

Le béton est ensuite coulé pour former la dalle de compression du plancher une fois des armatures, de type treillis soudés, posées sur chantier (avant et/ou après la fixation du dispositif 101 à la poutrelle P).The concrete is then poured to form the compression slab of the floor once the reinforcements, of the welded mesh type, have been installed on site (before and/or after fixing the device 101 to the beam P).

Une fois que le béton a été coulé et a terminé de prendre, le dispositif 101 se retrouve rigidement solidarisé au corps de la dalle de compression de sorte à former avec le plancher un tout-rigide.Once the concrete has been poured and has finished setting, the device 101 finds itself rigidly attached to the body of the compression slab so as to form an all-rigid structure with the floor.

Ainsi le dispositif 101 est rigidement solidarisé au corps de la dalle de compression du plancher en étant ancré dans celui-ci. Seuls les moyens d'accueil 102 dépassent au moins en partie de la face supérieure de la dalle de compression pour permettre à un opérateur de solidariser un ou des accessoires de construction au plancher en construction. De la sorte, on solidarise facilement et rapidement le dispositif 101 au plancher en cours de construction.Thus the device 101 is rigidly secured to the body of the floor compression slab by being anchored therein. Only the reception means 102 protrude at least partly from the upper face of the compression slab to allow an operator to secure one or more construction accessories to the floor under construction. In this way, the device 101 is easily and quickly secured to the floor during construction.

Un dispositif de solidarisation selon un troisième mode de réalisation particulier de l'invention est illustré à la figure 3.A securing device according to a third particular embodiment of the invention is illustrated in the Figure 3 .

Ce dispositif, généralement désigné en 201, est ici dédié à la solidarisation d'un accessoire de construction à un élément de construction. L'accessoire de construction peut être de tout type comme un élément de coffrage, un élément de sécurité tel qu'un garde-corps, un élément d'isolation thermique ...This device, generally designated 201, is here dedicated to securing a construction accessory to a construction element. The construction accessory can be of any type such as a formwork element, a safety element such as a guardrail, a thermal insulation element, etc.

Le dispositif 201 comporte des moyens d'accueil 202 de l'accessoire de construction.The device 201 includes means 202 for receiving the construction accessory.

Lesdits moyens d'accueil 202 comportent ici au moins un plot d'ancrage de l'accessoire de construction. Le plot d'ancrage est ici conformé sous la forme d'un fourreau 203. Le fourreau 203 est par exemple en métal.Said reception means 202 here comprise at least one anchoring stud of the construction accessory. The anchoring stud is here shaped in the form of a sheath 203. The sheath 203 is for example made of metal.

Le fourreau 203 est ici conformé de sorte à s'étendre selon un premier axe X. Le fourreau 203 est conformé en un solide de révolution. Le fourreau 203 est ici conformé extérieurement en un cylindre droit de génératrice le premier axe X.The sheath 203 is here shaped so as to extend along a first axis X. The sheath 203 is shaped like a solid of revolution. The sheath 203 is here shaped externally in a right cylinder of generator the first axis X.

Dans le cas présent, le fourreau 203 est creux. Ainsi une section radiale du fourreau 203 est de forme annulaire. De préférence les moyens d'accueil 202 comportent au moins un premier bouchon 205 pour boucher (temporairement ou de manière permanente) l'extrémité inférieure des moyens d'accueil 202.In the present case, the sheath 203 is hollow. Thus a radial section of the sheath 203 is of annular shape. Preferably the receiving means 202 comprise at least a first plug 205 to block (temporarily or permanently) the lower end of the receiving means 202.

Le premier bouchon 205 comble ainsi l'extrémité inférieure du fourreau 203.The first plug 205 thus fills the lower end of the sheath 203.

Ceci évite que du béton ne remonte dans le fourreau 203 lors de la coulée du béton formant un corps en béton de l'élément de construction ce qui pourrait gêner la solidarisation ultérieure de l'accessoire de construction audit élément.This prevents concrete from rising into the sheath 203 during the pouring of concrete forming a concrete body of the construction element, which could hinder the subsequent attachment of the construction accessory to said element.

De préférence les moyens d'accueil 202 comportent au moins un deuxième bouchon 204 pour boucher temporairement l'extrémité haute des moyens d'accueil 202.Preferably the reception means 202 comprise at least a second plug 204 to temporarily block the upper end of the reception means 202.

Le deuxième bouchon 204 comble ainsi temporairement l'extrémité supérieure du fourreau 203.The second plug 204 thus temporarily fills the upper end of the sheath 203.

Ceci évite une obstruction accidentelle du fourreau 203 (par la pluie, le gel, du béton ...) qui pourrait gêner la solidarisation ultérieure de l'accessoire de construction à l'élément de construction.This avoids accidental obstruction of the sheath 203 (by rain, frost, concrete, etc.) which could hinder the subsequent attachment of the construction accessory to the construction element.

Bien entendu le deuxième bouchon 204 est conformé pour pouvoir être retiré à tout moment afin de permettre la solidarisation de l'accessoire de construction à l'élément de construction. Le deuxième bouchon 204 est de préférence conformé pour pouvoir être retiré manuellement sans utilisation d'un outil. Par exemple le deuxième bouchon 204 est simplement emboité dans le fourreau 203 ou clipsé au fourreau 203.Of course the second plug 204 is shaped so that it can be removed at any time in order to allow the construction accessory to be joined to the construction element. The second plug 204 is preferably shaped so that it can be removed manually without using a tool. For example, the second cap 204 is simply fitted into the sheath 203 or clipped to the sheath 203.

Ladite pince d'accroche est ici conformée pour être fixée à une tête de poutrelle P.Said hanging clip is here shaped to be fixed to a beam head P.

La pince d'accroche est fixée aux moyens d'accueil 202 par exemple par soudage, par collage ...The hanging clip is fixed to the receiving means 202 for example by welding, by gluing, etc.

Ladite pince d'accroche comprend un premier mors 207 et un deuxième mors 208 mobiles l'un par rapport à l'autre.Said hooking clamp comprises a first jaw 207 and a second jaw 208 movable relative to each other.

Optionnellement la pince d'accroche comporte une platine 210 à laquelle est fixée le premier mors 207 de sorte que la platine 210 et le premier mors 207 sont immobiles l'un par rapport à l'autre. Le premier mors 207 est par exemple d'une seule pièce avec la platine 210.Optionally the hanging clamp comprises a plate 210 to which the first jaw 207 is fixed so that the plate 210 and the first jaw 207 are stationary relative to each other. The first jaw 207 is for example made in one piece with the plate 210.

La platine 210 s'étend rectilignement dans un plan sensiblement horizontal.The plate 210 extends rectilinearly in a substantially horizontal plane.

Le premier mors 207 s'étend à partir de l'une des côtés latéraux de la platine 210 à partir de la face inférieure de celle-ci.The first jaw 207 extends from one of the lateral sides of the plate 210 from the lower face thereof.

Le premier mors 207 est ici conformé en un crochet. A cet effet, l'extrémité libre du premier mors 207 (opposée à celle rattachant le premier mors à la platine) forme un rabat du premier mors 207. De préférence, le rabat s'étend vers l'intérieur de la pince. Le rabat s'étend ici en direction de la face inférieure de la platine 210. Préférentiellement le premier mors 207 est conformé de sorte à épouser la forme de la tête de poutrelle que le premier mors 207 encadrera à terme.The first jaw 207 is here shaped like a hook. For this purpose, the free end of the first jaw 207 (opposite to that attaching the first jaw to the plate) forms a flap of the first jaw 207. Preferably, the flap extends towards the inside of the pliers. The flap extends here towards the lower face of the plate 210. Preferably the first jaw 207 is shaped so as to match the shape of the head of the beam which the first jaw 207 will ultimately frame.

A cet effet, le premier mors 207 est conformé de sorte que sa surface interne (i.e. sa surface tournée vers l'intérieur de la pince et destinée à venir en regard de la tête de poutrelle) comporte :

  • une zone plane destinée à venir reposer contre l'une des faces latérales de la semelle de la poutrelle,
  • le rabat destiné à venir reposer contre l'une des faces latérales de l'âme de la poutrelle, le rabat formant également une zone plane, et
  • une zone de jonction s'étendant de manière inclinée entre la zone plane et le rabat selon une inclinaison identique ou similaire à la zone de jonction entre l'âme et la semelle de la poutrelle, la zone de jonction du premier mors 207 étant destinée à venir reposer contre la zone de jonction correspondante de la tête de poutrelle.
For this purpose, the first jaw 207 is shaped so that its internal surface (ie its surface facing the inside of the clamp and intended to come opposite the head of the beam) comprises:
  • a flat area intended to rest against one of the lateral faces of the sole of the beam,
  • the flap intended to rest against one of the lateral faces of the web of the beam, the flap also forming a flat zone, and
  • a junction zone extending in an inclined manner between the flat zone and the flap at an inclination identical or similar to the junction zone between the core and the sole of the beam, the junction zone of the first jaw 207 being intended to rest against the corresponding junction zone of the head of the beam.

Optionnellement seule la platine est fixée aux moyens d'accueil par exemple par soudage, par collage ... Ainsi le premier mors 207 comme la platine 210 sont immobiles vis-à-vis des moyens d'accueil 202.Optionally only the plate is fixed to the receiving means for example by welding, by gluing, etc. Thus the first jaw 207 like the plate 210 are immobile with respect to the receiving means 202.

Par exemple les moyens d'accueil 202 sont agencés dans la platine 210 du même côté latéral que le premier mors 207 mais à niveau de la face supérieure de la platine 210. Comme pour le premier mode de réalisation, les moyens d'accueil 202 sont donc agencés au niveau du premier mors 207 i.e. au niveau du mors fixe.For example, the receiving means 202 are arranged in the plate 210 on the same lateral side as the first jaw 207 but level with the upper face of the plate 210. As for the first embodiment, the receiving means 202 are therefore arranged at the level of the first jaw 207 i.e. at the level of the fixed jaw.

Par ailleurs, au niveau de son deuxième côté latéral, la platine 210 comporte au moins un passage à travers lequel peut se déplacer le deuxième mors 208 relativement au premier mors. Par exemple le deuxième mors 208 se déplace vis-à-vis du premier mors 207 par coulissement. Par exemple le passage consiste en un rail de coulissement du deuxième mors 208.Furthermore, at its second lateral side, the plate 210 has at least one passage through which the second jaw 208 can move relative to the first jaw. For example, the second jaw 208 moves relative to the first jaw 207 by sliding. For example, the passage consists of a sliding rail of the second jaw 208.

Par ailleurs le deuxième mors 208 est conformé de sorte à présenter une extrémité libre, destinée à venir au contact de la poutrelle, en pointe.Furthermore, the second jaw 208 is shaped so as to have a free end, intended to come into contact with the beam, at a point.

Ainsi lorsque le deuxième mors 208 coulisse dans le rail son extrémité libre finit par buter contre la poutrelle bloquant le dispositif sur la poutrelle.So when the second jaw 208 slides in the rail its free end ends up abutting against the beam blocking the device on the beam.

Par exemple le deuxième mors 208 présente deux faces inclinées l'une par rapport à l'autre de sorte à former conjointement ladite pointe.For example, the second jaw 208 has two faces inclined relative to each other so as to jointly form said tip.

De la sorte, le deuxième mors 208 est conformé sensiblement comme le verrou du deuxième mode de réalisation.In this way, the second jaw 208 is shaped substantially like the lock of the second embodiment.

De préférence, la platine 210 comporte plusieurs passages et l'on peut ainsi venir agencer le deuxième mors 208 dans l'un ou l'autre des passages selon la distance que l'on souhaite avoir entre les deux mors 207, 208. Préférentiellement, on peut venir coulisser le deuxième mors 208 dans chacun desdites passages. De préférence, les différents rails de chaque passage sont parallèles entre eux. Par exemple au moins l'un des rails s'étend dans un plan incliné vis-à-vis d'un plan vertical et/ou au moins un des rails s'étend dans un plan droit vis-à-vis d'un plan vertical.Preferably, the plate 210 has several passages and it is thus possible to arrange the second jaw 208 in one or the other of the passages depending on the distance that is wishes to have between the two jaws 207, 208. Preferably, the second jaw 208 can be slid into each of said passages. Preferably, the different rails of each passage are parallel to each other. For example at least one of the rails extends in an inclined plane with respect to a vertical plane and/or at least one of the rails extends in a straight plane with respect to a plane vertical.

Ainsi il est possible de modifier la position relative entre le premier mors 207 et le deuxième mors 208 au moins par déplacement du deuxième mors 208 dans l'un des passages et optionnellement en plus en associant le deuxième mors 208 à des passages différents de la platine 210.Thus it is possible to modify the relative position between the first jaw 207 and the second jaw 208 at least by moving the second jaw 208 in one of the passages and optionally in addition by associating the second jaw 208 with different passages of the plate 210.

Les deux mors 207, 208 et la platine 210 forment ainsi un cavalier, les mors 207, 208 formant les ailes dudit cavalier et la platine 210 sa portion centrale. Optionnellement, au moins l'un des mors 207, 208 et/ou la platine 210 est en métal. Alternativement au moins l'un des mors 207, 208 et/ou la platine 210 est en plastique. Dans le cas présent les deux mors 207, 208 et la platine 210 sont en métal.The two jaws 207, 208 and the plate 210 thus form a rider, the jaws 207, 208 forming the wings of said rider and the plate 210 its central portion. Optionally, at least one of the jaws 207, 208 and/or the plate 210 is made of metal. Alternatively at least one of the jaws 207, 208 and/or the plate 210 is made of plastic. In the present case the two jaws 207, 208 and the plate 210 are made of metal.

On retient que le deuxième mors 208 forme ici une pièce indépendante de la platine 210.We note that the second jaw 208 here forms an independent part of the plate 210.

En service, le dispositif 201 qui vient d'être décrit est implanté directement sur un chantier une fois au moins une poutrelle posée. Le dispositif 201 est implanté de préférence une fois les différentes poutrelles posées et des entrevous agencés entre les poutrelles.In service, the device 201 which has just been described is installed directly on a construction site once at least one beam has been installed. The device 201 is preferably installed once the different beams have been installed and spaces arranged between the beams.

Pour fixer le dispositif 201, le dispositif 201 est placé au-dessus de la tête d'une des poutrelles en place de sorte que la face inférieure de la platine 210 repose au moins en partie sur la semelle supérieure de ladite poutrelle et de sorte que le premier mors 207 épouse au moins en partie le côté de ladite poutrelle.To fix the device 201, the device 201 is placed above the head of one of the beams in place so that the lower face of the plate 210 rests at least partly on the upper flange of said beam and so that the first jaw 207 matches at least partly the side of said beam.

Dans cette position, le deuxième mors 208 est coulissé dans l'un des rails de la platine 210 jusqu'à ce que le deuxième mors 208 vienne en contact avec ladite poutrelle. Optionnellement, un marteau peut être utilisé pour enfoncer davantage le deuxième mors 208 dans le dispositif 201. Dans cette position la tête de poutrelle est enserrée dans le cavalier.In this position, the second jaw 208 is slid into one of the rails of the plate 210 until the second jaw 208 comes into contact with said beam. Optionally, a hammer can be used to further drive the second jaw 208 into the device 201. In this position the head of the beam is clamped in the jumper.

Dans cette position le fourreau 203 s'étend sur le côté de la tête de poutrelle. Dans cette position le fourreau 203 s'étend à la verticale.In this position the sheath 203 extends on the side of the beam head. In this position the sheath 203 extends vertically.

De la sorte, on solidarise facilement et rapidement le dispositif 201 à la poutrelle. En outre, le dispositif 201 peut s'adapter à des profils différents de poutrelles.In this way, the device 201 is easily and quickly secured to the beam. In addition, the device 201 can adapt to different beam profiles.

De manière avantageuse, le cavalier épouse la forme de la tête de la poutrelle au moins au niveau du premier mors 207 ce qui renforce la solidarisation du dispositif 201 à la poutrelle.Advantageously, the rider matches the shape of the head of the beam at least at the level of the first jaw 207, which reinforces the attachment of the device 201 to the beam.

En particulier, le rabat vient en appui contre l'âme ce qui renforce la solidarisation du dispositif 201 à la poutrelle.In particular, the flap rests against the core which reinforces the connection of the device 201 to the beam.

On retient par ailleurs que le premier mors 207 est ici fixe vis-à-vis de la poutrelle : c'est le deuxième mors 208 seulement qui se déplace vis-à-vis du premier mors 207 pour assurer la fixation du dispositif 201 à la poutrelle. Le béton est ensuite coulé pour former la dalle de compression du plancher une fois des armatures, de type treillis soudés, posées sur chantier (avant et/ou après la fixation du dispositif à la poutrelle).We also note that the first jaw 207 is here fixed with respect to the beam: it is only the second jaw 208 which moves with respect to the first jaw 207 to ensure the fixing of the device 201 to the beam. The concrete is then poured to form the compression slab of the floor once the reinforcements, such as welded mesh, have been installed on site (before and/or after fixing the device to the beam).

Une fois que le béton a été coulé et a terminé de prendre, le dispositif 201 se retrouve rigidement solidarisé au corps de la dalle de compression de sorte à former avec le plancher un tout-rigide.Once the concrete has been poured and has finished setting, the device 201 finds itself rigidly attached to the body of the compression slab so as to form an all-rigid structure with the floor.

Ainsi le dispositif 201 est rigidement solidarisé au corps de la dalle de compression du plancher en étant ancré dans celui-ci. Seuls les moyens d'accueil 202 dépassent au moins en partie de la face supérieure de la dalle de compression pour permettre à un opérateur de solidariser un ou des accessoires de construction au plancher en construction. De la sorte, on solidarise facilement et rapidement le dispositif 201 au plancher en cours de construction.Thus the device 201 is rigidly secured to the body of the floor compression slab by being anchored therein. Only the reception means 202 protrude at least partly from the upper face of the compression slab to allow an operator to secure one or more construction accessories to the floor under construction. In this way, the device 201 is easily and quickly secured to the floor during construction.

Bien entendu l'invention n'est pas limitée aux modes de réalisation décrits et on peut y apporter des variantes sans sortir du cadre de l'invention tel que défini par les revendications.Of course, the invention is not limited to the embodiments described and variations can be made without departing from the scope of the invention as defined by the claims.

Ainsi les moyens d'accueil pourront être différents de ce qui a été indiqué et par exemple comporter un nombre différent de plot d'ancrage.Thus the reception means may be different from what has been indicated and for example include a different number of anchoring studs.

Le ou les plots d'ancrage pourront être différents de ce qui a été indiqué. Par exemple un plot d'ancrage pourra avoir une section carré, carré, rectangulaire ... Un plot d'ancrage pourra être partiellement plein et non complètement creux.The anchoring pad(s) may be different from what was indicated. For example, an anchoring pad may have a square, square, rectangular section, etc. An anchoring pad may be partially solid and not completely hollow.

Le plot d'ancrage pourra ne pas être saillant : par exemple le plot d'ancrage pourra être un orifice ménagé dans une platine du dispositif.The anchoring stud may not be protruding: for example the anchoring stud may be an orifice formed in a plate of the device.

Les moyens d'accueil pourront ne pas comporter de bouchons ou bien un nombre différent de bouchons que ce qui a été indiqué.The reception means may not include caps or a different number of caps than what has been indicated.

Bien qu'ici au moins l'un des bouchons puisse être retiré des moyens d'accueil, ledit bouchon pourra demeurer en place mais être conformé pour pouvoir être transpercé notamment, bien que non exclusivement, par l'accessoire de construction directement.Although here at least one of the plugs can be removed from the reception means, said plug can remain in place but be shaped to be able to be pierced in particular, although not exclusively, by the construction accessory directly.

Au moins l'un des bouchons pourra ainsi être un simple opercule de faible épaisseur (en matière plastique, en matière métallique ...)At least one of the caps could thus be a simple, thin cover (made of plastic, metal, etc.)

Au moins l'un des bouchons pourra être d'une seule pièce avec les moyens d'accueil.At least one of the caps may be in one piece with the reception means.

Bien qu'ici les moyens d'accroche soient en métal, les moyens d'accroche pourront être dans un autre matériau par exemple en plastique et/ou bien qu'ici les moyens d'accueil soit en métal, les moyens d'accueil pourront être dans un autre matériau et par exemple en plastique.Although here the attachment means are made of metal, the attachment means could be in another material for example plastic and/or although here the reception means either in metal, the reception means could be in another material and for example in plastic.

Bien qu'ici les moyens d'accroche soient solidarisés aux moyens d'accueil par soudage, d'autres moyens de solidarisation sont envisageables comme par exemple par collage, par vissage ...Although here the attachment means are secured to the receiving means by welding, other means of attachment are possible such as for example by gluing, by screwing, etc.

Par ailleurs, les moyens d'accroche et les moyens d'accueil pourront être d'une seule et même pièce au lieu d'être solidarisés entre eux. On pourra par exemple mouler d'un seul tenant les moyens d'accroche et les moyens d'accueil. Bien qu'ici seul le deuxième mors soit mobile, les deux mors pourront être mobiles par rapport aux moyens d'accueil ou seulement le premier mors. Le mouvement de l'un des mors vis-à-vis des moyens d'accueil et/ou de l'autre mors pourra être différent de ce qui a été indiqué et être par exemple un mouvement de rotation.Furthermore, the hanging means and the reception means may be in one and the same piece instead of being joined together. For example, we could mold the hanging means and the reception means in one piece. Although here only the second jaw is movable, the two jaws may be movable relative to the reception means or only the first jaw. The movement of one of the jaws with respect to the receiving means and/or the other jaw may be different from what has been indicated and be for example a rotational movement.

La platine pourra ne comporter qu'un seul passage associé au deuxième mors et non plusieurs. La platine et/ou l'un des mors pourra comporter des moyens de guidage du mouvement de l'un des mors dans la platine. Par exemple les moyens de guidage pourront comporter une partie mâle (de type vis) coulissant dans une partie femelle (de type lumière). En présence des moyens de guidage on pourra optionnellement s'affranchir de rails de coulissement.The plate may only have one passage associated with the second jaw and not several. The plate and/or one of the jaws may include means for guiding the movement of one of the jaws in the plate. For example, the guide means may include a male part (screw type) sliding in a female part (light type). In the presence of guide means, we can optionally do without sliding rails.

Le dispositif ne pourra comporte qu'un seul mors.The device may only have one jaw.

Bien qu'ici la platine et les mors du deuxième mode de réalisation et du troisième mode de réalisation soient pleins, au moins l'un de ces éléments (platine, premier mors, deuxième mors) pourra être creux. Par exemple au moins l'un de ces éléments pourra être composé de tôles solidarisées entre elles. Par exemple dans le troisième mode de réalisation le deuxième mors pourra n'être formé que de deux flancs latéraux raccordés par une face supérieure et/ou une face arrière. L'un ou les deux faces formant la pointe pourront donc être fictives et délimitées par les arêtes des flancs et/ou de la face arrière (la face arrière pouvant elle-même former l'une des faces formant la pointe).Although here the plate and the jaws of the second embodiment and the third embodiment are solid, at least one of these elements (plate, first jaw, second jaw) may be hollow. For example at least one of these elements could be composed of sheets joined together. For example in the third embodiment the second jaw may only be formed of two lateral sides connected by an upper face and/or a rear face. One or both faces forming the tip could therefore be fictitious and delimited by the edges of the sides and/or the rear face (the rear face itself being able to form one of the faces forming the point).

Le verrou du deuxième mode de réalisation pourra être conformé pour pouvoir s'insérer à la fois entre la poutrelle et l'embase et à la fois entre la platine et l'embase. Le verrou du deuxième mode de réalisation pourra être conformé pour pouvoir s'insérer entre l'embase et/ou le crochet du deuxième mors d'une part et entre la platine et/ou la poutrelle d'une autre part.The lock of the second embodiment can be shaped to be able to be inserted both between the beam and the base and both between the plate and the base. The lock of the second embodiment can be shaped to be able to be inserted between the base and/or the hook of the second jaw on the one hand and between the plate and/or the beam on the other hand.

On pourra bien entendu mixer les différents modes de réalisation entre eux. Par exemple le deuxième mors pourra être monté coulissant vis-à-vis de la platine (comme dans le deuxième mode de réalisation et le troisième mode de réalisation) sans toutefois pouvoir sortir de la platine pour être agencé dans un autre passage (comme dans le premier mode de réalisation de l'invention où une extrémité du deuxième mors est définitivement fixée à la platine). Par exemple au moins l'extrémité libre du deuxième mors du troisième mode de réalisation pourra comporter un rabat pour venir en appui contre la poutrelle (comme dans le premier mode de réalisation et le deuxième mode de réalisation) et/ou être conformée pour épouser la forme de la poutrelle associée (comme dans le deuxième mode de réalisation). Par exemple on pourra avoir un deuxième mors présentant une pointe (comme dans le troisième mode de réalisation) associé à un verrou supplémentaire (comme dans le deuxième mode de réalisation). Le verrou (quel que soit le mode de réalisation considéré) pourra être de tout type et non pas seulement un bloc présentant une pointe. Par exemple le verrou pourra être de type vis - écrou.We can of course mix the different embodiments together. For example, the second jaw could be mounted sliding vis-à-vis the plate (as in the second embodiment and the third embodiment) without however being able to exit the plate to be arranged in another passage (as in the first embodiment of the invention where one end of the second jaw is permanently fixed to the plate). For example at least the free end of the second jaw of the third embodiment may include a flap to come to bear against the beam (as in the first embodiment and the second embodiment) and/or be shaped to fit the shape of the associated beam (as in the second embodiment). For example, we could have a second jaw having a point (as in the third embodiment) associated with an additional lock (as in the second embodiment). The lock (whatever the embodiment considered) can be of any type and not just a block with a point. For example, the lock could be of the screw-nut type.

Bien qu'ici le dispositif soit lié à une dalle de compression d'un plancher à poutrelles et entrevous, le dispositif pourra être lié à tout type de corps en béton d'éléments de construction comme des éléments de construction directement fabriqués sur chantier (tel qu'une poutre, un balcon, une terrasse, un plancher ...) ou d'éléments de construction préfabriqués (prédalle, pré-poutre ...). Dans ce dernier cas, le dispositif sera solidarisé au corps en béton de l'élément de construction de sorte que l'élément de construction livré sur site sera déjà équipé du dispositif de l'invention. Ceci permettra aux opérateurs de plus facilement attacher un accessoire de construction.Although here the device is linked to a compression slab of a floor with beams and interjoists, the device can be linked to any type of concrete body of construction elements such as elements of construction directly manufactured on site (such as a beam, a balcony, a terrace, a floor, etc.) or prefabricated construction elements (pre-slab, pre-beam, etc.). In the latter case, the device will be secured to the concrete body of the construction element so that the construction element delivered to site will already be equipped with the device of the invention. This will allow operators to more easily attach a construction accessory.

Par ailleurs bien qu'ici le dispositif soit fixé à la tête de poutrelle, le dispositif pourra être conformé pour être lié (alternativement ou en complément) à au moins une autre zone de la poutrelle.Furthermore, although here the device is fixed to the head of the beam, the device can be shaped to be linked (alternatively or in addition) to at least one other zone of the beam.

On peut donc voir que l'invention peut être installée à de multiples endroits d'un chantier ce qui est très avantageux. En particulier, le dispositif peut être agencé à proximité de bords libres du chantier (type bord libre du plancher, trémie notamment trémie d'escalier ...) afin qu'un accessoire de sécurité tel qu'un garde-corps puisse y être solidarisé.We can therefore see that the invention can be installed in multiple locations on a construction site, which is very advantageous. In particular, the device can be arranged near free edges of the construction site (such as free edge of the floor, hopper in particular stair hopper, etc.) so that a safety accessory such as a guardrail can be secured there. .

D'autres accessoires de construction que ce qui a été indiqué pourront être solidarisés au dispositif comme par exemple des gaines (électriques, hydrauliques ...) ; des réservations, des éléments coudés (par exemple pour la remontée de gaines vers les arrivées d'eau froides et chaudes d'une maison et/ou d'un appartement)...Other construction accessories than what has been indicated may be attached to the device such as for example ducts (electrical, hydraulic, etc.); reservations, elbow elements (for example for raising ducts towards the cold and hot water inlets of a house and/or apartment)...

Le dispositif pourra comporter une ou des indications d'utilisation (par exemple une couleur particulière, un code alphanumérique ...) comme par exemple au moins une indication de son sens d'utilisation. Typiquement, au moins une indication pourra être inscrite au niveau de l'extrémité inférieure et/ou au niveau de l'extrémité supérieure du dispositif et par exemple sur le ou les bouchons des moyens d'accueil.The device may include one or more indications of use (for example a particular color, an alphanumeric code, etc.) such as at least one indication of its direction of use. Typically, at least one indication may be written at the lower end and/or at the upper end of the device and for example on the cap(s) of the receiving means.
