Abstract

Bracket fastening device for platforms provided with a safety member in which the brackets 17 carrying a decking 19 are connected together in the horizontal plane by a square tube 15, each bracket 17 being locked to the bar 15 by vertical flanges 22 and a bolt 21, characterised in that the bar 15 is blocked in square sleeves 12 each interacting with an angle section 6 of the vertical flange 6b, which angle section comprises a cut-out 10 which can penetrate on a passing rod 2 secured to a wall 1, each passing rod 2 ending with a head 5 on which there is normally clamped a lever 26 bent into the shape of a J and articulated under each angle section 6 so as to block this angle section on a head 5 of a passing rod 2.

Description

Actuellement on doit recourir à deux ensembles distincts d'organes pour accrocher des consoles de plates-formes de travail en encorbellement. Currently we must use two separate sets of organs to hang consoles from cantilevered work platforms.

En effet, il est nécessaire de disposer d'une barre maintenue contre le béton de la face avant d'un mur pignon par des sabots ou organes analogues, ces derniers étant bloqués par des ancrages, puis on est amené à accrocher sur la barre les consoles. Indeed, it is necessary to have a bar held against the concrete of the front face of a gable wall by shoes or the like, the latter being blocked by anchors, then it is necessary to hang on the bar the consoles.

Pour passer d'une hauteur à une autre, par exemple d'un étage à l'autre, on doit disposer de deux jeux de barres dont un jeu est au niveau supérieur. On peut alors relever l'ensemble des consoles et les accrocher à la barre supérieure. On doit ensuite récupérer la barre inférieure. To move from one height to another, for example from one floor to another, two busbars must be available, one of which is on the upper level. We can then raise all the consoles and hang them on the upper bar. We must then recover the lower bar.

La présente invention remédie à ces inconvénients en regroupant l'ensemble barres, consoles, plateforme en un tout solidaire que liron accroche directement sur les ancrages placés dans le mur tout en maintenant la sécurité exigée. The present invention overcomes these drawbacks by grouping together the bars, consoles, platform in a solid whole that liron hangs directly on the anchors placed in the wall while maintaining the required security.

Conformément à l'invention, le dispositif d'accrochage de consoles pour plates-formes munies d'un organe de sécurité dans lequel les consoles portant un platelage sont reliées entre elles dans le plan horizontal par un tube carré, chaque console étant verrouillée sur la barre par des ailes verticales et un verrou, est caractérisé en ce que la barre est bloquée dans des manchons carrés coopérant chacun avec une équerre de l'aile verticale équerre qui comporte une découpe pouvant pénétrer sur une tige passante solidaires d'un mur, chaque tige passante se terminant par une tête contre laquelle vient prendre appui normalement un levier coudé en J articulé sous chaque équerre de façon à bloquer cette équerre sur une tête d'une tige passante. In accordance with the invention, the device for hanging consoles for platforms provided with a safety member in which the consoles carrying a deck are connected together in the horizontal plane by a square tube, each console being locked on the bar by vertical wings and a lock, is characterized in that the bar is locked in square sleeves each cooperating with a square of the vertical square wing which has a cutout which can penetrate a pass rod secured to a wall, each pass rod ending in a head against which normally comes to rest a bent J-shaped lever hinged under each bracket so as to block this bracket on a head of a pass rod.

Suivant une autre caractéristique de l'invention, chaque levier est muni, à son extrémité libre, d'un tirant terminé à sa partie supérieure par un anneau de préhension permettant de déverrouiller chaque levier lors d'un démontage de la barre. According to another characteristic of the invention, each lever is provided, at its free end, with a tie rod terminated at its upper part by a gripping ring making it possible to unlock each lever during disassembly of the bar.

Diverses autres caractéristiques de l'invention ressortent d'ailleurs de la description détaillée qui suit. Various other characteristics of the invention will also emerge from the detailed description which follows.

Une forme de réalisation de l'objet de l'invention est représentée, à titre d'exemple non limitatif, aux dessins annexés. An embodiment of the object of the invention is shown, by way of nonlimiting example, in the accompanying drawings.

La fig. 1 est une élévation, partie en coupe, du dispositif d'accrochage de consoles non repliables sur la face avant d'un mur. Fig. 1 is an elevation, partly in section, of the device for hanging non-folding consoles on the front face of a wall.

La fig. 2 est une vue arrière, à plus petite échelle, schématique montrant la fixation d'une barre à consoles. Fig. 2 is a rear view, on a smaller scale, schematic showing the attachment of a console bar.

La fig. 3 est une coupe, à plus grande échelle, suivant la ligne III-III de la fig. 1. Fig. 3 is a section, on a larger scale, along the line III-III of FIG. 1.

La fig. 4 est une vue de face correspondant à la fig. 3. Fig. 4 is a front view corresponding to FIG. 3.

A la fig. 1, on a représenté un mur 1 par exemple en béton qui porte dans le sens transversal des tiges passantes 2. In fig. 1, a wall 1 has been shown, for example of concrete, which carries transverse rods 2 in the transverse direction.

Au fur et à mesure de la construction du mur 1, il est disposé un certain nombre de tiges passantes 2 le long d'une ligne horizontale, ces tiges passantes peuvent demeurer dans le mur ou au contraire être retirées au moment de la finition. As the wall 1 is constructed, a number of pass rods 2 are arranged along a horizontal line, these pass rods may remain in the wall or, on the contrary, be removed at the time of finishing.

Chaque tige passante 2 est maintenue, côté intérieur du mur 1 par une contre-plaque 3 et un écrou 4, tandis que sa face avant porte une tête 5 placée à une certaine distance de la face avant la du mur 1. Ainsi, il est possible de mettre en place sur chaque tige passante 2 une équerre 6 dont l'aile horizontale 6a supporte des flasques 7 et 8 percés chacun d'une lumière 9. Each pass rod 2 is held on the interior side of the wall 1 by a counter plate 3 and a nut 4, while its front face carries a head 5 placed at a certain distance from the front face of the wall 1. Thus, it is possible to set up on each pass rod 2 a bracket 6 whose horizontal wing 6a supports flanges 7 and 8 each pierced with a light 9.

L'aile verticale 6b de chaque équerre 6 présente une découpe 10 de forme triangulaire qui vient chevaucher la partie avant de chaque tige passante 2 entre la face avant la du mur 1 et la tête 5 de cette tige passante. Un manchon 12 à section carrée, muni sur ses faces latérales de doigts 13 est placé entre les flasques 7, 8 et les doigts 13 sont logés dans les lumières 9 de ces flasques en permettant ainsi un déplacement longitudinal de chaque manchon carré 12 soit vers la droite, soit vers la gauche, ce qui permet de mettre en place aisément une barre 15 à section carrée portant les consoles 17 qui sont fixées sur la barre 15 par tous moyens convenables y compris par soudure. 112 désigne une vis portée par la face supérieure du manchon 12 permettant le blocage de la barre 15 après positionnement de cette barre. The vertical wing 6b of each bracket 6 has a cutout 10 of triangular shape which overlaps the front part of each pass rod 2 between the front face 1a of the wall 1 and the head 5 of this pass rod. A sleeve 12 of square section, provided on its lateral faces with fingers 13 is placed between the flanges 7, 8 and the fingers 13 are housed in the slots 9 of these flanges thereby allowing a longitudinal displacement of each square sleeve 12 either towards the right or to the left, which makes it possible to easily install a bar 15 with a square section carrying the brackets 17 which are fixed to the bar 15 by any suitable means including by welding. 112 designates a screw carried by the upper face of the sleeve 12 allowing the bar 15 to be blocked after positioning of this bar.

Comme cela est visible à la fig. 1, les consoles 17 d'un type classique portent sur la traverse horizontale supérieure 17a des profilés 18 en I maintenant un platelage 19. As can be seen in fig. 1, the brackets 17 of a conventional type carry on the upper horizontal crosspiece 17a profiles 18 in I maintaining a deck 19.

I1 est possible également soit sur le platelage 19, soit sur la traverse horizontale supérieure 17a de fixer un garde-fou fixe ou mobile 20. It is also possible either on the deck 19 or on the upper horizontal cross member 17a to fix a fixed or mobile railing 20.

Dans le cas présent, la fixation des consoles 17 sur la barre carrée 15 se fait par l'intermédiaire d'un verrou 21 traversant des trous percés dans deux ailes 22 verticales et solidaires de la partie inférieure arrière de la traverse horizontale supérieure 17a. In the present case, the brackets 17 are fixed to the square bar 15 by means of a lock 21 passing through holes drilled in two vertical wings 22 and integral with the rear lower part of the upper horizontal cross member 17a.

Finalement, et par mesure de sécurité, chaque équerre 6 porte, sous son aile horizontale 6a, un arceau 24 servant à la fixation d'un axe 25 sur lequel est articulé un levier 26 sensiblement conformé en J, l'une des extrémités 26a du levier 26 s'engageant derrière chaque tête 5 des tiges passantes 2 et chaque extrémité 26b portant un tirant 28 terminé par un anneau de préhension 29 de façon que lorsque l'ensemble des consoles solidaires de la barre longitudinale 15 est en place, chaque levier 26 forme un verrou ne permettant pas aux équerres 6 de s'échapper de la face avant des tiges passantes 2 et empêchant tout soulèvement de l'ensemble de la pièce donc des consoles.En effet, le poids des tirants 28 assure toujours un blocage du levier 26 dans la position représentée à la fig. 3 et l'agrippage derrière la pièce 5 empêche le mouvement de bas en haut de l'ensemble de la plate-forme. Finally, and as a safety measure, each bracket 6 carries, under its horizontal wing 6a, a hoop 24 used for fixing a pin 25 on which is articulated a lever 26 substantially shaped as J, one of the ends 26a of the lever 26 engaging behind each head 5 of the passing rods 2 and each end 26b carrying a tie rod 28 terminated by a gripping ring 29 so that when all of the consoles integral with the longitudinal bar 15 are in place, each lever 26 forms a lock that does not allow the brackets 6 to escape from the front face of the pass rods 2 and prevents any lifting of the entire part, therefore of the brackets. Indeed, the weight of the tie rods 28 always ensures a locking of the lever 26 in the position shown in FIG. 3 and the gripping behind the part 5 prevents movement from bottom to top of the whole platform.

Pour démonter l'ensemble on est amené d'abord à suspendre, à l'extrémité d'un filin manoeuvré par exemple à l'aide d'une grue, l'ensemble barre 15 et consoles 17 puis de déverrouiller les leviers 26 en soulevant les tirants 28 par leur anneau de préhension 29 de façon à dégager les équerres 6 des parties avant des tiges passantes 2. To dismantle the assembly, it is first of all necessary to suspend, at the end of a rope maneuvered for example using a crane, the assembly of bars 15 and consoles 17, then to unlock the levers 26 by lifting the tie rods 28 by their gripping ring 29 so as to release the brackets 6 from the front parts of the pass rods 2.

Lorsque l'on remet en place l'ensemble susdécrit (barre carrée 15 et consoles 17), il suffit de mettre en place sur les tiges passantes 2 les équerres 6 puis de ramener dans leur position de verrouillage les leviers 26. When the above-described assembly is replaced (square bar 15 and brackets 17), it suffices to place the brackets 6 on the pass rods 2 and then to return the levers 26 to their locking position.

Bien que l'on ait décrit un ensemble avec des consoles 17 non démontables, il est possible d'utiliser des consoles démontables et/ou repliables.  Although a set has been described with non-removable consoles 17, it is possible to use removable and / or foldable consoles.
