Description

Device for securing a construction accessory to a beam, method of securing and associated construction element

The invention relates to a device for securing a construction accessory to a beam.

The invention also relates to a construction element comprising such a device and in particular a construction element comprising a concrete body and at least one beam extending in the concrete body.

The invention also relates to a method for fixing such a fastening device to the associated beam.

BACKGROUND OF THE INVENTION

On a construction site of a building, the realization of a floor consists for example in installing a set of beams resting on shear walls or beams of the building, so as to cover the entire surface of the floor to be produced, then install interjoists between the joists.

For this type of floor, no guardrails are arranged around the surface of the floor to be made, yet ensuring the safety of workers and users by preventing the fall of objects and people.

OBJECT OF THE INVENTION

An object of the invention is to provide a device for securing a construction accessory to a beam which ensures good attachment to the beam in question.

An object of the invention is also to propose a construction element comprising such a securing device.

An object of the invention is also to provide a method for fixing such a device to the beam.

With a view to achieving this object, there is proposed, according to the invention, a securing device intended to secure a construction accessory to at least one beam, the device comprising at least:

• receiving means intended in service to receive the construction accessory, and
• hooking means to the beam, said hooking means comprising a hooking clamp which is configured to enclose a beam in service in order to fix the device to said beam.

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 detachment or a tilting of the invention.

Furthermore, the invention is simple in construction and inexpensive to produce.

Furthermore, 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.

Optionally, the reception means include a sheath serving as an anchoring stud for the construction accessory in service.

Optionally, the receiving means comprise at least one plug to plug one of the ends of the receiving means.

Optionally, the cap is shaped so that it can be removed from the receiving means.

Optionally, the gripper comprises at least one jaw mounted movable vis-à-vis the receiving means.

Optionally, the gripper comprises at least two jaws, at least one of which is movably mounted relative to the receiving means.

Optionally, the other of the jaws is fixed vis-à-vis the receiving means.

Optionally, at least the jaw mounted movable vis-à-vis the receiving means is carried by an elastically deformable tab of the clamp.

Optionally, the gripper comprises a plate, at least the jaw mounted movable vis-à-vis the receiving means being able to move through at least one passage of the plate.

Optionally, the device comprises a lock to block the movement of the jaw in the passage of the plate.

Optionally, at least one jaw of the clamp has a free end forming a flap capable of coming to bear in service on the beam.

Optionally, at least one jaw of the gripper is shaped so as to match in service the shape of the beam against which said jaw rests.

Optionally, the clamp is shaped to grip a beam head.

The invention also relates to a construction element comprising a concrete body and at least one beam embedded in the concrete body, the construction element comprising a device as mentioned above arranged in the construction element so that the clamp encloses the beam and so that the receiving means extend at least partly outside the concrete body.

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. The operators only have to introduce said construction accessory into the receiving means to secure the accessory to the construction element, which is quick and easy.

If the construction element is not a prefabricated construction element, it always proves to be very simple for an operator to secure the securing device to the beam before pouring the concrete body onto the assembly making it possible to secure the concrete body device. Here again, the invention offers a quick and easy solution.

Optionally the construction element is a floor.

The invention also relates to a method for fixing a device as mentioned above to at least one beam comprising the step of enclosing the beam by the clamp of the attachment means.

Throughout this application, the terms “lower”, “upper”, “height”, “length”… must be understood in relation to the position of the device in service, ie the position of the device once fixed to the beam.

Other characteristics and advantages of the invention will become apparent on reading the following description of particular non-limiting embodiments of the invention.

DETAILED DESCRIPTION OF THE INVENTION

A securing device according to a first particular embodiment of the invention is illustrated in .

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 security element such as a guardrail, a thermal insulation element, etc.

The device 1 comprises means 2 for receiving the construction accessory.

Said receiving means 2 here comprise at least one anchoring stud for 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.

The sheath 3 is here shaped so as to extend along a first axis X. The sheath 3 is shaped as a solid of revolution. The sheath 3 is here shaped externally as a right cylinder generating the first axis X.

In the present case, the sheath 3 is hollow. Thus a radial section of the sheath 3 is of annular shape.

Preferably, the receiving means 2 comprise at least a first plug 5 to plug (temporarily or permanently) the lower end of the receiving means 2.

The first plug 5 thus fills the lower end of the sheath 3.

This prevents concrete from rising in the sheath 3 during the casting of the concrete forming a concrete body of the construction element which could interfere with the subsequent attachment of the construction accessory to said element.

Preferably the receiving means 2 comprise at least a second plug 4 to temporarily block the upper end of the receiving means 2.

The second plug 4 thus temporarily fills the upper end of the sheath 3.

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.

Of course, the second cap 4 is shaped so that it can be removed at any time in order to allow the attachment of the construction accessory 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 plug 4 is simply fitted into the sheath 3 or clipped to the sheath 3.

Furthermore, the device 1 comprises means 6 for attaching the receiving means 2 to at least one beam.

Said attachment means 6 comprise at least one attachment clip. Said hooking clamp is here shaped to be fixed to a beam head P.

The attachment clamp is fixed to the receiving means 2 for example by welding, by gluing, etc.

Said gripping clamp comprises a first jaw 7 and a second jaw 8 that are movable relative to each other.

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 vis-à-vis the receiving means 2.

The second jaw 8 is movably mounted on the first jaw 7 by an elastically deformable tab 9.

Typically tab 9 is of spring material.

Thus it is possible to modify the relative position between the first jaw 7 and the second jaw 8 thanks to said tab 9.

According to a preferred embodiment, at least one of the jaws is also made of elastically deformable material. Preferably again, the two jaws 7, 8 are made of an elastically deformable material.

Here, the entire gripping clamp is made of elastically deformable material.

Whether we consider the lug 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 made of steel such as mangano-siliceous steel.

The clamp is preferably in one piece. Thus the lug 9 and the two jaws 7, 8 are made in one piece.

The two jaws 7, 8 and the leg 9 are preferably shaped like a rider, the jaws 7, 8 forming the wings of said rider and the leg 9 its central portion.

Optionally, the first jaw 7 is shaped as a blade. The first jaw 7 extends for example in a single plane when the gripper is in a state of rest (i.e. it is not subjected to 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 leg 9 is shaped like a blade. The leg 9 extends for example in a single plane in the resting state of the clamp. The leg 9 extends for example orthogonally to the first jaw 7.

Optionally, the second jaw 8 is shaped as a blade. Here, at least the attachment end of the second jaw 8 to the leg 9 as well as its central portion extend in a first plane in the clamp resting state. This first plane is parallel to the single plane in which extends the first jaw 7 in the clamp resting state.

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 clamp is at the state of rest. The second plane is here inclined with respect to the first plane.

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 gripper. The flap 10 extends here in the direction of an underside of the tab 9.

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. The device 1 is preferably implanted once the various beams have been laid and interjoists arranged between the beams.

To fix device 1, device 1 is placed above the head of one of the P beams in place. The second jaw 8 is offset from the first jaw 7 so that the device 1 can come around the head of the beam P, the latter thus being housed inside the space delimited by the rider.

The second jaw 8 is then released which allows the clamp to grip the head of the beam P ensuring the fixing of the device 1 to the beam P.

In this position the sheath 3 extends along the head of the beam. In this position the sheath 3 extends vertically.

In this way, the device 1 is easily and quickly secured to the beam P. In addition, the device 1 can be adapted to different profiles of beams.

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 attachment of the device to the beam P.

It is also noted that the first jaw 7 is here fixed vis-à-vis the beam P: it is the second jaw 8 only which moves vis-à-vis the first jaw to ensure the fixing of the device 1 to the beam P.

The concrete is then poured to form the floor compression slab once the reinforcements, of the welded mesh type, have been placed on site (before and/or after the device has been fixed to the beam).

Once the concrete has been poured and has finished setting, the device 1 finds itself rigidly secured to the body of the compression slab so as to form an all-rigid structure with the floor.

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 under construction.

A securing device according to a second particular embodiment of the invention is illustrated in .

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 security element such as a guardrail, a thermal insulation element, etc.

The device 101 comprises means 102 for receiving the construction accessory.

Said reception means 102 here comprise at least one anchoring stud for 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.

The sheath 103 is here shaped so as to extend along a first axis X. The sheath 103 is shaped as a solid of revolution. The sheath 103 is here shaped externally as a right cylinder with generatrix the first axis X.

In this case, the sheath 103 is hollow. Thus a radial section of the sheath 103 is of annular shape.

Preferably the receiving means 102 comprise at least a first stopper to plug (temporarily or permanently) the lower end of the receiving means 102.

The first plug thus fills the lower end of the sheath 103.

This prevents concrete from rising in the sheath 103 during the casting of the concrete forming a concrete body of the construction element, which could interfere with the subsequent attachment of the construction accessory to said element.

Preferably, the receiving means 102 comprise at least one second plug 104 to temporarily block the upper end of the receiving means 102.

The second plug 104 thus temporarily fills the upper end of the sheath 103.

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.

Of course, the second plug 104 is shaped so that it can be removed at any time in order to allow the attachment of 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 plug 104 is simply fitted into the sheath 103 or clipped to the sheath 103.

Furthermore, the device 101 comprises means 6 for attaching the receiving means 102 to at least one beam P.

Said attachment means 106 comprise at least one attachment clamp.

Said hooking clamp is here shaped to be fixed to a beam head P.

The attachment clamp is fixed to the receiving means 102 for example by welding, by gluing, etc.

Said gripping clamp comprises a first jaw 107 and a second jaw 108 movable relative to each other.

Optionally, the gripping clamp comprises a plate 110 to which the first jaw 107 is fixed so that the plate 110 and the first jaw 107 are immobile with respect to each other. The first jaw 107 is for example in one piece with the plate 110.

The plate 110 extends rectilinearly in a substantially horizontal plane.

The first jaw 107 extends from one of the lateral sides of the plate 110 from the underside of the latter.

The first bit 107 here is shaped like a hook. For this purpose, the free end of the first jaw 107 (opposite to that connecting 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 gripper. The flap here extends 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 that the first jaw 107 will eventually frame.

For this purpose, the first jaw 107 is shaped so that its internal surface (i.e. its surface facing the inside of the gripper and intended to come opposite the beam head P) comprises:

• a flat area intended to come to rest against one of the side faces of the sole of the beam P,
• the flap intended to come to rest against one of the side 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 according to an identical or similar inclination to the junction zone between the web and the flange 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.

Optionally only the plate 110 is fixed to the receiving means, for example by welding, by gluing, etc. Thus the first jaws 107 like the plate 110 are immobile vis-à-vis the receiving means 102.

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.

Furthermore, at its second lateral side, the plate 110 comprises 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 vis-à-vis the first jaws 107 by sliding. For example, the passage consists of a sliding rail for the second jaw 108.

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 gripper. The flap here extends towards the underside of the plate 110.

Preferably, the second jaw 108 is shaped so as to match the shape of the beam head P that the second jaw 108 will eventually frame.

For this purpose, the second jaw 108 is shaped so that its internal surface (i.e. its surface facing the inside of the gripper and intended to come opposite the beam head P) comprises:

• a flat zone intended to come to rest against the other of the side faces of the flange of the beam P,
• the flap intended to come to rest against the other of the side 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 according to an identical or similar inclination to the junction zone between the web and the flange 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.

Preferably, the plate 110 has several passages and it is thus possible to arrange the base in one or the other of the passages according to the distance that one wishes to have between the two jaws. Preferably, the base can be slid into each of said passages. Preferably, the various 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.

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.

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.

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 this case the two jaws 107, 108 and the plate 110 are made of metal.

We note that the second jaw 108 here forms an independent part of the plate 110.

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 that is inserted between the base and the plate 110 and /or between the base and the P beam.

The latch 111 is for example shaped as a block having two faces inclined relative to each other so as to jointly form a tip capable of being inserted between the base and the plate 110 and/or between the base and beam head P.

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 laid. The device 1 is preferably implanted once the various beams have been laid and interjoists arranged between the beams.

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 the said beam P and so that the first jaw 107 marries at least in part the side of said beam P.

In this position, the base of the second jaw 108 is slid in one of the rails of the plate until the second jaw 108 comes into contact with said beam P.

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 hold the second jaw 108 in position vis-à-vis the plate 110 and the beam P. Optionally, a hammer can be used to drive the point further into device 101.

In this position the head of beam P is clamped in the rider.

In this position the sleeve 103 extends on the side of the beam head P. In this position the sleeve 103 extends vertically.

In this way, the device 101 is easily and quickly secured to the beam P. In addition, the device 101 can be adapted to different profiles of beams.

Advantageously, the rider matches 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.

In particular, the flaps come to bear against the web, which reinforces the attachment of the device 101 to the beam P.

It is also noted that the first jaw 107 is here fixed vis-à-vis the beam P: it is the second jaw 108 only which moves vis-à-vis the first jaw 107 to ensure the fixing of the device 101 to the P beam.

The concrete is then poured to form the compression slab of the floor once the reinforcements, of the welded mesh type, have been placed on site (before and/or after the fixing of the device 101 to the beam P).

Once the concrete has been poured and has finished setting, the device 101 finds itself rigidly secured to the body of the compression slab so as to form an all-rigid structure with the floor.

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 under construction.

A securing device according to a third particular embodiment of the invention is illustrated in .

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 security element such as a guardrail, a thermal insulation element, etc.

The device 201 includes means 202 for receiving the construction accessory.

Said reception means 202 here comprise at least one anchoring stud for 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.

The sheath 203 is here shaped so as to extend along a first axis X. The sheath 203 is shaped as a solid of revolution. The sheath 203 is here shaped externally as a right cylinder generating the first axis X.

In this 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 plug (temporarily or permanently) the lower end of the receiving means 202.

The first stopper 205 thus fills the lower end of the sheath 203.

This prevents concrete from rising in the sleeve 203 during the casting of the concrete forming a concrete body of the construction element, which could interfere with the subsequent attachment of the construction accessory to said element.

Preferably, the receiving means 202 comprise at least one second plug 204 to temporarily block the upper end of the receiving means 202.

The second plug 204 thus temporarily fills the upper end of the sheath 203.

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.

Of course, the second cap 204 is shaped so that it can be removed at any time in order to allow the attachment of the construction accessory 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 plug 204 is simply fitted into the sheath 203 or clipped to the sheath 203.

Said hooking clamp is here shaped to be fixed to a beam head P.

The attachment clamp is fixed to the receiving means 202 for example by welding, by gluing, etc.

Said gripping clamp comprises a first jaw 207 and a second jaw 208 that are movable relative to each other.

Optionally, the gripping clamp comprises a plate 210 to which the first jaw 207 is fixed so that the plate 210 and the first jaw 207 are immobile with respect to each other. The first bit 207 is for example in one piece with the plate 210.

The plate 210 extends rectilinearly in a substantially horizontal plane.

The first jaw 207 extends from one of the lateral sides of the plate 210 from the underside of the latter.

The first bit 207 here is shaped like a hook. To this end, the free end of the first jaw 207 (opposite to that connecting the first jaw to the plate) forms a flap of the first jaw 207. Preferably, the flap extends towards the inside of the gripper. The flap here extends towards the underside of the plate 210.

Preferably, the first jaw 207 is shaped so as to match the shape of the beam head that the first jaw 207 will eventually frame.

For this purpose, the first jaw 207 is shaped so that its internal surface (i.e. its surface facing the inside of the gripper and intended to come opposite the head of the beam) comprises:

• a flat area intended to come to rest against one of the side faces of the flange of the beam,
• the flap intended to come to rest against one of the side 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 according to an identical or similar inclination to the junction zone between the web and the flange of the beam, the junction zone of the first jaw 207 being intended to come to rest against the corresponding junction zone of the head of the beam.

Optionally, only the plate is fixed to the receiving means, for example by welding, by gluing, etc. Thus the first jaws 207 like the plate 210 are immobile vis-à-vis the receiving means 202.

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.

Furthermore, at its second lateral side, the plate 210 comprises at least one passage through which the second jaw 208 can move relative to the first jaw. For example, the second jaw 208 moves vis-à-vis the first jaw 207 by sliding. For example, the passage consists of a sliding rail for the second jaw 208.

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.

Thus, when the second jaw 208 slides in the rail, its free end ends up abutting against the beam blocking the device on the beam.

For example, the second jaw 208 has two faces inclined relative to each other so as to jointly form said tip.

In this way, the second jaw 208 is shaped substantially like the lock of the second embodiment.

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 according to the distance that one wishes to have between the two jaws 207, 208. Preferably, the second jaw 208 can be slid in each of said passages. Preferably, the various 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.

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.

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 this case the two jaws 207, 208 and the plate 210 are made of metal.

We note that the second jaw 208 here forms an independent part of the plate 210.

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 various beams have been laid and interjoists arranged between the beams.

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 the said beam and so that the first jaw 207 matches at least partly the side of said beam.

In this position, the second jaw 208 is slid in 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 enclosed in the rider.

In this position the sleeve 203 extends on the side of the beam head. In this position the sheath 203 extends vertically.

In this way, the device 201 is fastened easily and quickly to the beam. In addition, the device 201 can adapt to different beam profiles.

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.

In particular, the flap bears against the core, which reinforces the attachment of the device 201 to the beam.

It is also noted that the first jaw 207 is here fixed vis-à-vis the beam: it is the second jaw 208 only which moves vis-à-vis the first jaw 207 to ensure the fixing of the device 201 to the beam.

The concrete is then poured to form the floor compression slab once the reinforcements, of the welded mesh type, have been placed on site (before and/or after the device has been fixed to the beam).

Once the concrete has been poured and has finished setting, the device 201 finds itself rigidly secured to the body of the compression slab so as to form an all-rigid structure with the floor.

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 in part 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 attached to the floor under construction.

Of course, the invention is not limited to the embodiments described and variations can be made thereto without departing from the scope of the invention as defined by the claims.

Thus the reception means may be different from what has been indicated and for example include a different number of anchoring studs.

The anchoring stud(s) may be different from what has been indicated. For example, an anchoring stud may have a square, square, rectangular section... An anchoring stud may be partially solid and not completely hollow.

The anchoring stud may not be projecting: for example the anchoring stud may be an orifice made in a plate of the device.

The means of reception may not include plugs or a different number of plugs than what has been indicated.

Although here at least one of the plugs can be removed from the receiving means, said plug may remain in place but be shaped to be able to be pierced in particular, although not exclusively, by the construction accessory directly.

At least one of the plugs can thus be a simple thin lid (plastic, metal, etc.)

At least one of the caps may be in one piece with the means of reception.

Although here the attachment means are made of metal, the attachment means may be in another material, for example plastic, and/or although here the receiving means is made of metal, the receiving means may be in another material and for example plastic.

Although here the means of attachment are secured to the means of reception by welding, other means of securing are possible such as for example by gluing, by screwing, etc.

Furthermore, the means of attachment and the means of reception may be in one and the same piece instead of being integral with each other. For example, we can mold the means of attachment and the means of reception in one piece.

Although here only the second jaw is mobile, the two jaws may be mobile in relation to the receiving means or only the first jaw. The movement of one of the jaws vis-à-vis the receiving means and/or the other jaw may be different from what has been indicated and may for example be a rotational movement.

The plate may have only 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 comprise a male part (of the screw type) sliding in a female part (of the light type). In the presence of guide means, it is optionally possible to dispense with sliding rails.

The device may only have one jaw.

Although here the plate and the jaws of the second embodiment and of 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 may be composed of sheets secured together. For example, in the third embodiment, the second jaw may be formed of only two lateral flanks connected by an upper face and/or a rear face. One or both faces forming the point may therefore be fictitious and delimited by the edges of the flanks and/or of the rear face (the rear face may itself form one of the faces forming the point).

The lock of the second embodiment may 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 may 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.

It will of course be possible to mix the different embodiments together. For example, the second jaw may be slidably mounted with respect to the plate (as in the second embodiment and the third embodiment) without however being able to leave 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 bear against the beam (as in the first embodiment and the second embodiment) and/or be shaped to match the shape of the associated beam (as in the second embodiment). For example, it is possible to have a second jaw having a point (as in the third embodiment) associated with an additional lock (as in the second embodiment). The lock (regardless of the embodiment considered) may be of any type and not just a block having a point. For example, the lock may be of the screw-nut type.

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 construction elements 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 on site will already be equipped with the device of the invention. This will allow operators to more easily attach a construction accessory.

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.

It can therefore be seen that the invention can be installed at multiple locations on a construction site, which is very advantageous. In particular, the device can be arranged close to the free edges of the site (free edge of the floor type, hopper in particular stairway hopper, etc.) so that a safety accessory such as a guardrail can be secured there.

Construction accessories other than what has been indicated may be attached to the device, such as sheaths (electrical, hydraulic, etc.); reservations, elbow elements (for example for the rise of ducts towards the cold and hot water inlets of a house and/or an apartment)…

The device may include one or more indications for use (for example a particular color, an alphanumeric code, etc.) such as, for example, at least one indication of its direction of use. Typically, at least one indication may be inscribed at the level of the lower end and/or at the level of the upper end of the device and for example on the plug or plugs of the receiving means.
