Description

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

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

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 two reinforcements extending in the concrete body.

The invention also relates to a method for attaching such a securing device to the associated fittings.

BACKGROUND OF THE INVENTION

On a building construction site, the construction of a cast-in-place floor or a floor with beams and interjoists is rarely secure. Indeed, 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 obviate, at least in part, the aforementioned drawback.

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 frames.

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

• receiving means intended in service to receive the construction accessory, and
• means for attaching to the armatures, said attachment means comprising at least a first lug for attaching to at least a first armature, said lug comprising at least two legs framing said first armature in service, at least one second lug attaches to at least one second frame, said leg comprising at least two legs coming to frame said second frame in service, the two legs extending opposite one another.

In this way, the invention makes it possible to be well implanted by being fixed to two separate frames, the arrangement in opposite directions of the legs favoring this good implantation. In particular, this ensures pinching of the invention between the two reinforcements. This makes it possible in particular to avoid a detachment of one of the legs 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.

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, at least the first leg is arranged so that its first leg is at a given distance from a lower end of the device identical to the distance separating the second leg from said first leg at an upper end of the device.

Optionally, at least one area of at least one of the legs is textured.

Optionally, the two legs of the same leg extend parallel to each other.

Optionally, at least one of the legs of the first leg extends parallel to at least one of the legs of the second leg.

Optionally, the attachment means comprise a third tab associated with the first tab and a fourth tab associated with the second tab so that the attachment means comprise a first pair of tabs and a second pair of tabs.

Optionally, the third leg extends in the same direction as the first leg so as to frame the same frame and wherein the fourth leg extends in the same direction as the second leg so as to frame the same frame.

Optionally, at least two lugs extend along a first flank of the receiving means and at least two lugs extend along a second flank of the receiving means opposite the first flank.

The invention also relates to a construction element comprising a concrete body and at least two reinforcements embedded in the concrete body, the construction element comprising a device as mentioned above arranged in the construction element so that the legs frame each one of the reinforcements 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 arrange the securing device to the reinforcements 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 the frames comprising the successive steps of:

• arrange the device between the two frames so that the legs both extend between the two frames,
• rotate the device so that the two legs of each leg come to frame a respective one of the frames.

In this way, it suffices to pivot the device to ensure its installation and its attachment to the frames, which is quick and easy. Usually, but not exclusively, a simple quarter turn is sufficient.

It is therefore retained that the invention can be implemented without tools.

For the entire present 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 frames.

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 Figures 1 and 2.

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 4 to block (temporarily or permanently) the lower end of the receiving means 2.

The first cap 4 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 5 to temporarily block the upper end of the receiving means 2.

The second plug 5 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 plug 5 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 5 is preferably shaped so that it can be removed manually without using a tool. For example, the second plug 5 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 the frames.

Said attachment means 6 here comprise at least one first attachment lug 7 to at least one first frame and at least one second attachment lug 10 to at least one second frame.

The first leg 7 comprises at least two legs. In the present case, the first leg 7 comprises only two legs, namely a first leg 8 and a second leg 9. The two legs are identical here.

In the present case, the two legs 8, 9 extend from the sheath 3 towards the outside of the device. In particular the two legs 8, 9 are secured at one of their first ends to the sheath 3, their second ends being free. The two legs 8, 9 are therefore immobile with respect to the sheath 3. The two legs 8, 9 are for example welded to the sheath 3.

The first leg 8 and the second leg 9 are arranged so that the first end of the first leg 8 is at a given distance from the lower end of the device 1 (along the first axis X), given distance which is identical to the distance separating the first end of the second leg 9 from the upper end of the device 1.

The device 1 can thus be used indifferently in one direction or the other.

Each leg 8, 9 here extends straight. The two legs 8, 9 also extend parallel to each other and to a second axis A which is orthogonal to the first axis X. The first leg 8 also extends below the second leg 9 without touching it. The two axes A ₁ , A ₂ along which the two legs extend thus define a plane which is here parallel to the first axis X.

The two legs 8, 9 draw between them an open space which can receive at least one frame.

The two legs 8, 9 of the first leg 7 are identical to each other in terms of shapes and dimensions. Typically each leg 8, 9 is shaped as a rod and for example a disc section rod. Each leg 8, 9 is thus full.

Each leg 8, 9 is for example made of metal.

Each leg 8, 9 comprises over at least part of its length (considered along the axis along which said leg extends) a textured zone. This facilitates the attachment of the legs 8, 9 to the frames and prevents the device from slipping with respect to the frames. For example, said zone is notched, ribbed, grooved, etc. In the present case, the entire leg 8 (respectively 9) is textured. Preferably the entire corresponding tab 7 is textured.

Similarly, the second leg 10 comprises at least two legs. In the present case, the second leg 10 comprises only two legs, namely a first leg 11 and a second leg 12. The two legs 11, 12 are identical here.

In the present case, the two legs 11, 12 extend from the sheath 3 towards the outside of the device 1. In particular the two legs 11, 12 are secured at one of their first ends to the sheath 3, their second ends being free. The two legs 11, 12 are therefore immobile with respect to the sheath 3. For example the legs 11, 12 are welded to the sheath 3.

The first leg 11 and the second leg 12 are arranged so that the first end of the first leg 11 is at a given distance from the lower end of the device 1 (along the first axis X), given distance which is identical to the distance separating the first end of the second leg 12 from the upper end of the device.

The device 1 can thus be used indifferently in one direction or the other.

Each leg 11, 12 here extends straight. The two legs 11, 12 also extend parallel to each other and to a third axis B which is orthogonal to the first axis X. The first leg 11 also extends below the second leg 12 without touching it. The two axes B ₁ and B ₂ along which the two legs 11, 12 extend define a plane which is here parallel to the first axis X.

The two legs 11, 12 also draw between them an open space that can receive at least one reinforcement.

In addition, the second leg 10 is arranged so that the third axis B is parallel to the second axis A associated with the two legs 8, 9 of the first leg 7.

The two legs 11, 12 of the second leg 10 are identical to each other in terms of shapes and dimensions. Typically each leg 11, 12 is shaped as a rod and for example a disc section rod. Each leg 11, 12 is thus full.

The legs 11, 12 are for example made of metal.

Each leg 11, 12 comprises over at least part of its length (considered along the axis along which said leg extends) a textured zone. This facilitates the attachment of the legs 11, 12 to the frames and prevents the device 1 from slipping with respect to the frames. For example, said zone is notched, ribbed, grooved, etc. In the present case, the entire leg 11 (respectively 12) is textured. Preferably the entire corresponding tab 10 is textured.

Preferably, the legs 8, 9 of the first tab 7 and those 11, 12 of the second tab 10 are identical to each other in terms of shape and dimensions.

More precisely here, the first leg 8 of the first leg 7 and the first leg 11 of the second leg 10 are aligned. They preferably extend coaxially with each other. According to one option, the first leg 8 of the first leg 7 and the first leg 11 of the second leg 10 are in one and the same piece. The same rod thus forms the first leg 8 of the first leg 7 and the first leg 11 of the second leg 10.

More precisely here, the second leg 9 of the first leg 7 and the second leg 12 of the second leg 10 are aligned. They preferably extend coaxially with each other. According to one option, the second leg 9 of the first leg 7 and the second leg 12 of the second leg 10 are in one and the same piece.

The device 1 therefore comprises here a first rod forming the first leg 8 of the first leg 7 and the first leg 11 of the second leg 10 and a second rod forming the second leg 9 of the first leg 7 and the second leg 12 of the second leg 10.

Typically the first rod is welded at its central section to sleeve 3 and the second rod is welded at its central section to sleeve 3.

The manufacture of the device 1 thus proves to be simple and rapid.

Preferably, the hooking means 6 comprise a third leg 13 associated with the first leg 7 and a fourth leg 14 associated with the second leg 10 so that the hooking means 6 comprise a first pair of legs (the first leg 7 and the third leg 13) and a second pair of legs (the second leg 10 and the fourth leg 14).

The first pair of lugs 7, 13 allows attachment to the same first frame and the second pair of lugs 10, 14 allows attachment to the same second frame.

The four legs 7, 10, 13, 14 are here identical to each other.

The attachment means 6 optionally only have four legs 7, 10, 13, 14.

We will now describe the third leg 13. The third leg 13 comprises at least two legs. In the present case the third leg 13 comprises only two legs, namely a first leg 15 and a second leg 16. The two legs 15, 16 are identical here.

In the present case, the two legs 15, 16 extend from the sheath 3 towards the outside of the device 1. In particular the two legs 15, 16 are secured at one of their first ends to the sheath 3, their second ends being free. The two legs 15, 16 are therefore immobile with respect to the sheath 3. The two legs 15, 16 are for example welded to the sheath 3.

The first leg 15 and the second leg 16 are arranged so that the first end of the first leg 15 is at a given distance from the lower end of the device 1 (along the first axis X), given distance which is identical to the distance separating the first end of the second leg 16 from the upper end of the device 1.

The device 1 can thus be used indifferently in one direction or the other.

Each leg 15, 16 here extends straight. The two legs 15, 16 also extend parallel to each other and to a fourth axis C which is orthogonal to the first axis X. The first leg 15 also extends below the second leg 16 without touching it. The two axes C ₁ and C ₂ along which the two legs 15, 16 extend define a plane which is here parallel to the first axis X.

The two legs 15, 16 therefore form between them an open space which can receive at least one frame.

The two legs 15, 16 of the third leg 13 are identical to each other in terms of shapes and dimensions. Typically each leg 15, 16 is shaped as a rod and for example a disc section rod. Each leg 15, 16 is thus full.

Each leg 15, 16 is for example made of metal.

Each leg 15, 16 comprises over at least part of its length (considered along the axis along which said leg extends) a textured zone. This facilitates the attachment of the legs to the frames and prevents the device 1 from slipping with respect to the frames. For example, said zone is notched, ribbed, grooved, etc. In this case, the entire leg 15, 16 is textured. Preferably the entire corresponding leg 13 is textured.

Each leg 15, 16 comprises over at least part of its length (considered along the axis along which said leg extends) a textured zone. This facilitates the attachment of the legs 15, 16 to the frames and prevents the device 1 from slipping with respect to the frames. For example, said zone is notched, ribbed, grooved, etc. In this case, the entire leg 15, 16 is textured. Preferably the entire corresponding leg 13 is textured.

Similarly the fourth leg 14 comprises at least two legs. In the present case the fourth leg 14 comprises only two legs, namely a first leg 17 and a second leg 18. The two legs 17, 18 are identical here.

In the present case, the two legs 17, 18 extend from the sheath 3 towards the outside of the device 1. In particular the two legs 17, 18 are secured at one of their first ends to the sheath 3, their second ends being free. The two legs 17, 18 are therefore immobile with respect to the sheath 3. For example the legs 17, 18 are welded to the sheath 3.

The first leg 17 and the second leg 18 are arranged so that the first end of the first leg 17 is at a given distance from the lower end of the device 1 (along the first axis X), given distance which is identical to the distance separating the first end of the second leg 18 from the upper end of the device 1.

The device 1 can thus be used indifferently in one direction or the other.

Each leg 17, 18 here extends straight. The two legs 17, 18 also extend parallel to each other and to a fifth axis D which is orthogonal to the first axis X. The first leg 17 also extends below the second leg 18 without touching it. The two axes D ₁ , D ₂ along which the two legs 17, 18 extend define a plane which is here parallel to the first axis X.

The two legs 17, 18 draw between them an open space which can receive at least one reinforcement.

In addition, the fourth leg 14 is arranged so that the fifth axis D is parallel to the fourth axis C associated with the two legs of the third leg 13.

The two legs 17, 18 of the fourth leg 14 are identical to each other in terms of shapes and dimensions. Typically each leg 17, 18 is shaped as a rod and for example a disc section rod. Each leg 17, 18 is thus full.

The legs 17, 18 are for example made of metal.

Each leg 17, 18 comprises over at least part of its length (considered along the axis along which said leg extends) a textured zone. This facilitates the attachment of the legs 17, 18 to the frames and prevents slipping of the device 1 vis-à-vis the frames. For example, said zone is notched, ribbed, grooved, etc. In this case, the entire leg 17, 18 is textured. Preferably the entire corresponding tab 14 is textured.

Preferably, the legs 15, 16 of the third leg 13 and those 17, 18 of the fourth leg 14 are identical to each other in terms of shape and dimensions.

More precisely here, the first leg 15 of the third leg 13 and the first leg 17 of the fourth leg 14 are aligned. They preferably extend coaxially with each other. According to one option, the first leg 15 of the third leg 13 and the first leg 17 of the fourth leg 14 are in one and the same piece. The same rod thus forms the first leg 15 of the third leg 13 and the first leg 17 of the fourth leg 14.

More precisely here, the second leg 16 of the third leg 13 and the second leg 18 of the fourth leg 14 are aligned. They preferably extend coaxially with each other. According to one option, the second leg 16 of the third leg 13 and the second leg 14 of the fourth leg 18 are in one and the same piece.

The device therefore comprises here a third rod forming the first leg 15 of the third leg 13 and the first leg 17 of the fourth leg 14 and a fourth rod forming the second leg 16 of the third leg 13 and the second leg 18 of the fourth paw 14.

Typically the third rod is welded at its central section to sleeve 3 and the fourth rod is welded at its central section to sleeve 3.

The manufacture of the device 1 thus proves to be simple and rapid.

Preferably, the tabs 7, 10, 13, 14 are arranged so that the third tab 13 and the fourth tab 14 extend along a first side of the receiving means 2 and the first tab 7 and the second leg 10 extend along a second flank of the receiving means 2, the first flank and the second flank forming the two right and left sides of the receiving means 2.

This ensures very good stabilization of the device 1 on the frames, in particular avoiding its tilting.

Optionally the first lug 7 and the second lug 10 are secured to a zone of the sheath 3 which is radially opposite to the zone of the sheath 3 to which the third lug 13 and the fourth lug 14 are secured.

With reference to the , the device 1 which has just been described is installed directly on a construction site once at least a first network of reinforcements has been installed on shear walls and/or beams of a building under construction. This first network of reinforcements is generally a welded mesh comprising a first series of reinforcements parallel to each other and a second series of reinforcements parallel to each other and orthogonal to the reinforcements of the first series of reinforcements.

To fix the device 1 to the network of armatures, the device 1 is placed in the center of a space delimited by four armatures (two of the first series 101, 102 and two of the second series 103, 104) then simply pivoted around its axis (here the first axis X) until the legs of the first pair of legs 7, 13 frame one of the frames 102 of the first series (alternatively of the second series) and the legs of the second pair of legs 10, 14 frame the other of the frames 101 of the first series (alternatively of the second series).

The device 1 is thus fixed simply to the frames by rotation. In this case a simple quarter turn is enough.

In this position the legs extend orthogonally to the frames they frame. The legs therefore extend parallel to the frames of the second series (alternatively of the first series).

In the example shown, device 1 is suspended from the frames.

Concrete is then poured to form the floor compression slab.

Once the concrete has been poured and has finished setting, the device 1 then 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.

Of course, the invention is not limited to the embodiment 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 or rectangular section, etc. An anchoring stud may be partially solid and not completely hollow.

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.

The legs may be of another shape than what has been described. For example, the legs could each be shaped like a hoop as illustrated in (and not formed of two separate legs without attachment between them). Thus, each tab may include an attachment portion of the two legs between them, said attachment portion being that secured to the receiving means. The attachment portion may be rounded or straight or even of a more complex shape.

The device may include a different number of legs than what has been indicated.

The legs may of course be different from each other and/or the legs of the same leg may be different from each other.

Each leg may have a different number of legs than indicated.

Although here the legs are textured, the legs can be smooth in part or in whole. As a variant or in addition to at least one textured zone present directly on the tab (and preferably one of the legs), at least one of the tabs may include a coating applied to the tab in whole or in part, said coating being an anti-slip coating such as for example a layer of material based on natural or artificial rubber. The coating will at least partially cover at least one of the legs. The textured appearance could be provided by an element already present on the leg (for example by using a threaded rod to form one of the legs, the thread forming a textured zone) or by creating it once the leg has been formed (by cutting For example).

The legs may be arranged differently from what has been described. For example, the first leg and the second leg could be arranged on two different sides of the receiving means as illustrated in and not on the same side as described.

The legs may be shaped differently from what has been indicated. For example, the legs may be of square or round section... The legs may be hollow and not solid... The free ends of the legs may be provided with an inclined surface (hook, blade, inclined plane, etc.) to facilitate the insertion of the frame between the two legs and/or limit the risk of shrinkage.

The two legs of at least one of the legs may be movable relative to each other (and not immobile to each other permanently as has been indicated here) in order to modify the spacing in height between the two legs (along the first axis X). This will allow the device to be able to adapt to different heights of reinforcement placed on site or in a manufacturing mould. For example, at least one of the legs may be partially or totally flexible in order to be able to move away from or move closer to the other leg of the leg. At least one of the legs can be movably mounted vis-à-vis the receiving means (for example by translation on a slide), the associated leg comprising means for temporarily locking the leg in a fixed position vis-à-vis - screw reception means once the target distance between the two legs reached.

The legs may be arranged differently from what has been indicated. For example, the two legs may extend towards each other, approaching towards their free ends instead of being parallel to each other. For example, although here the first legs of the first leg and of the second leg are aligned, they could be offset from each other axially (along the first axis) or radially (so as to be arranged one side or the other of the means of reception). For example, the first two legs may be parallel to each other but be arranged so as to be joined together in two distinct zones of the receiving means located on opposite sides as illustrated in . Although here the second legs of the first leg and the second leg are aligned, they may be offset from each other axially (along the first axis) or radially (so as to be arranged on one side or the other means of reception). For example, the two second legs may be parallel to each other but be arranged so as to be joined together in two distinct zones of the receiving means located on opposite sides as illustrated in .

It will of course be possible to mix the different embodiments together. For example, we can have only two legs (as illustrated in ) formed into arches (as illustrated in ).

The device may be arranged differently from what was indicated vis-à-vis the reinforcements. For example, the device may be arranged by being arranged at an angle vis-à-vis the frames. Thus the legs of at least one of the legs can extend obliquely with respect to the frame they frame and not orthogonally as indicated. The device may be arranged so that the lower end of the device rests on a ground, for example an already poured concrete base or a prefabricated element or a thermal breaker or an interjoist..., so that the device is not suspended in the void by the frames as indicated. The legs of at least one of the legs can frame several frames at the same time and not just one as indicated. In the case of a network of reinforcements with two series of reinforcements, the device can frame at least one of the reinforcements of the first series and at least one of the reinforcements of the second series. At least a second network of reinforcements can be placed on the first network of reinforcements once the device is in place.

Although understood, although here the device is linked to a compression slab of a floor directly manufactured on site (i.e. a so-called "plan" floor not including a prefabricated element), the device may be linked to concrete bodies of other construction elements directly manufactured on site (such as a beam, a balcony, a terrace, or a floor different from a flat floor such as for example a floor with beams and interjoists) or may be linked to 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.

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.

Optionally, locking means (whether or not forming part of the device) may be used to attach at least one of the legs to at least one of the frames that it frames (such as, for example, a metal link). Of course, these means are optional, the invention being able to be advantageously implemented by simply inserting the legs around the frames without additional locking means.

Although here the device can be used indifferently in one direction or the other, the device can be asymmetrical. Typically, the first end of the first leg of at least one of the legs may be at a given distance from the upper end of the device (along the first axis X) different from the distance separating the first end of the second leg of the same leg at the lower end of the device.

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 cap(s) of the

means of reception.
