Description

-1- Insert for a constituent element of a construction Technical field The present invention relates to an insert for a constituent element of a construction, preferably a facade panel. Background Art Generally, a facade panel of a construction comprises a connecting piece inserted into the panel for hooking an anchoring device for fixing the panel to a wall of the construction. The connecting piece comprises two fixed metal elements which are arranged in parallel, each comprising a portion embedded and / or buried within the construction material constituting the facade panel, and a semi-annular portion configured to receive and stabilize one end of the panel. a pin. This pin serves as a support for a fastening device called a “mounting system”. The latter comprises a metal bar, one end of which is folded back on itself to form a ring surrounding the pin. At the other end of the metal bar is inserted a plate. The latter is hung on the wall of the building (for example, via an anchor or any other suitable means). A metal lath being welded to one of said two fixed metal elements is then pushed, for example with a hammer, against the pin and one of the semi-annular portions so as to ensure that this pin remains in place.

The connecting piece must be fixed and inserted and / or embedded in the construction material constituting the facade panel while allowing the semi-annular portions to be accessible for inserting the pin. This is the reason why it is known to at least partially enclose these semi-annular portions in a block of expanded polystyrene which extends the edges of the facade panel. Thus, when fixing the facade panel on site, it suffices for a site worker to scrape the expanded polystyrene using a scraper (or any other suitable means) so as to release the semi-portions.

-2- ring and insert the pin previously circled in the end of the metal bar folded back on itself.

Said connecting piece, said metal lath and said block of expanded polystyrene form an insert of the facade panel for its attachment to the construction.

This insert and its use as described nevertheless have several disadvantages.

First, an execution of the assembly method of the mounting system and the pin with the insert is complex and time consuming.

In particular, the time required to release the semi-annular portions of the expanded polystyrene is important.

It may also happen that you have to make several attempts before correctly placing the pin between the two semi-annular portions.

Second, the use of the insert is not environmentally friendly.

Indeed, it requires scraping expanded polystyrene which then flies on the site and disperses in nature.

In addition, the polystyrene block has a fragile behavior and may deteriorate during transport or their implementation, which can make the assembly of the pin impossible.

Summary of the Invention An object of the present invention is to provide an insert for a building block, for example, a facade panel, which is simpler, faster and more environmentally friendly to use.

To this end, the invention provides an insert for a constituent element of a construction comprising: - a box at least partially delimiting a cavity; - an axis passing through the cavity; and - a connecting piece arranged at least partially in the cavity, mechanically coupled to the axis in the cavity, and able to rotate about the axis.

The insert according to the invention is at the same time simpler, faster and more ecological to use, in particular for fixing a facade panel to a

- 3 - construction. In fact, in view of the prior art described, it is no longer necessary to at least partially enclose a connecting piece in a block of expanded polystyrene because the box plays this role during the manufacture of the constituent element of construction. It is then sufficient to open and / or break the box on a construction site (if it is not partially open) to access the connection piece, which is simpler, faster and more ecological given the wide range. materials that are both manageable and ecological from which it can be made. The insert according to the present invention further provides another type of connecting piece which allows a simple and quick connection (preferably a male-female connector) with a fixing and / or anchoring device. In the particular case of a mounting system, it is no longer necessary to provide that one end of a metal bar of the mounting system is folded back on itself. The metal bar can directly cooperate with the connecting piece. For example, in a preferred embodiment where the connecting piece is tubular, the metal bar can be inserted therein, for example, by screwing and / or by clipping. Since the connecting piece can also rotate around the axis, it is possible to adjust the orientation of the fixing and / or anchoring device with respect to the constituent part of a construction including Pinsert. The axis and its mechanical coupling with the connecting piece are very advantageously provided in the insert, which makes it possible to effectively replace the pin system of the prior art and to eliminate all the site steps necessary for its placement.

It follows that the insert according to the present invention makes it possible to greatly reduce the number and the complexity of the various operations required on site. In particular, these operations and / or the method of using the insert according to the invention comprise (and, preferably, consist of): opening the box (if the latter is closed) to access the room. connection, turn the latter around the axis, cause a fixing and / or anchoring device to cooperate with the connection part (for example, by screwing and / or clipping). This insert is therefore quick and easy to use, with no significant ecological impact.

- 4- Preferably, the box can be made of at least one recyclable or recycled material which is ecological and respectful of and / or not harmful to the environment, unlike particles of expanded polystyrene. Such a material consists, for example, of wood and / or plastic.

Preferably, the box is made of recycled plastic. The box and / or the cavity are optionally parallelepipedal in a preferred manner, which can facilitate the design of the box. In general, such a box is easy, quick and inexpensive to manufacture. It generates little waste and additional weight to Vinsert, and therefore to the building block.

Optionally, the box includes a code, for example, a color, on an external face making it possible to visually identify the type of construction component for which the insert is intended.

Preferably, the box is delivered completely closed, the connecting piece then being completely arranged in the cavity. Preferably, the cavity is therefore completely delimited by the box upon delivery of the constituent element of the construction. It is in fact easier to design such an element from a poured and solidified building material such as concrete by embedding the closed box in it. In addition, the closure of the box ensures that the connecting piece will remain in the cavity during all stages of manufacture of the element and its transport to the job site, without protruding from one side of the element. It is in fact advantageous for the transport and storage of such elements that no part protrudes because it would risk breaking and / or complicating storage and / or transport, as well as the placement of these elements on site. To avoid any movement of the connecting piece around the axis during this step, the box further preferably includes removable and / or slidable side reinforcements arranged to hold the connecting piece in a fixed position in the cavity.

According to a very preferred embodiment of the invention, the box comprises a means of access to the cavity. Preferably, this means of access consists of at least one of:

-5- (a) a removable cover covering an opening of the box; (b) a breakable outer wall. In this case, the connecting piece is preferably completely arranged in the cavity (when the box is closed), this embodiment being prior to the use of the insert on site.

In case (a), the opening is preferably pre-existing in the sense that it is made in the box, for example, during the manufacture of the box, and then covered by a cover. The cover is preferably a face portion (preferably one face) of the box screwed and / or clipped and / or slid on the opening contour of the box and / or on side edges of the box (for example, by means of screws and / or reliefs hollowed out on an external face of the box), so that it is easy to move and / or slide on site. Optionally, the box includes hinges mechanically coupled to the cover to allow it to pivot about an axis or fulcrum.

Generally, any known type of cover and / or any type of cover stabilization over the opening can be used within the scope of this invention.

In case (b), the outer wall preferably consists of a face portion (preferably, a face) of the box which is thinner due to the rest of the box and / or which is made of a material of low strength and / or membrane, so that it is very easy to break and / or break by means of a construction tool, for example, a hammer and / or a knife, from the outside of the box, so as to release an opening in the box. Optionally, the box can be made homogeneously, without the structure of the wall referred to in (b) being distinguished in a particular way from the rest of the box. In particular, in this case, any face of the box preferably consists of a wall easily breakable with a construction tool. According to another embodiment of the preferred case (b), the box comprises two plastic half-shells which fit into each other to define the cavity, one of these two half-shells being made of a plastic. less thick and / or more

- 6 - fragile than the other, so that it constitutes said breakable outer wall. In addition, this half-shell is optionally also comparable to a removable cover of the box.

In both cases (a) and (b), said opening is preferably large enough so that several fingers of one hand, preferably one hand, can pass through it, so as to easily handle the connecting piece in the cavity. . In particular, the opening is preferably larger than a disc 5 centimeters in diameter. Access means other than those mentioned in (a) and (b) can be fully used within the framework of the invention. Preferably, such a means of access will include the existence or the possibility of creating such an opening.

Both in case (a) and in case (b), the box includes a means of access to the cavity so that, once delivered to the site, the box can be broken and / or opened to access the room. connection. As the latter is able to rotate around the axis, it is then possible to arrange it so as to connect and / or mechanically couple an anchoring device. According to one embodiment, in this case, preferably when the insert is used on site or after installation of the constituent element of the construction, the box comprises an opening (for example, that which was covered by a cover that the 'one has moved (case (a)) or that which has been carried out by breaking the wall (case (b)), and / or the connecting piece extends partially out of the cavity, through the opening.

The connecting piece preferably extends transversely to the axis, more preferably perpendicular to the axis. According to a preferred embodiment of the invention, an angle between a direction of extension of the connecting piece perpendicular to the axis and a vertical direction perpendicular to the axis varies by at most 200 °. The connecting piece can rotate around the axis, within the limits of the box. Advantageously, it is thus possible to adjust this angle on site in order to connect and / or secure and / or mechanically couple an anchoring device to the connecting part according to

- 7 - a predetermined orientation with the building component. This is particularly advantageous for the fastening of a facade panel to a building since it is necessary that the anchoring device can still fit properly to an anchoring point on the facade of the building after its connection and / or its securing and / or its mechanical coupling with the connecting piece of the insert. This angle gives sufficient freedom to make this adjustment. The angle is preferably between 15 ° and 25 ° when the facade panel is fixed to the facade (and therefore when the anchoring device connected and / or secured and / or mechanically coupled to the insert is adjusted on a point of anchoring of the facade). Preferably, there is a range of values for this angle for which the connecting piece is completely arranged in the cavity (during delivery to the site of the box, for example). Preferably, in the case where the box includes an opening as described, there is another range of values for this angle for which the connecting piece extends partially outside the cavity, through the opening. Specifically concerning the technical means allowing the connecting piece to be connected and / or secured and / or mechanically coupled to an anchoring and / or fixing device, preferred embodiments are presented below. This connecting piece is more preferably suitable for securing an anchoring and / or fixing device (for example, a mounting system) configured to suspend a constituent element from the construction preferably consisting of a facade panel.

The connecting piece is preferably tubular. It preferably comprises a threaded internal part. These embodiments are preferably combined. The existence of a threaded internal part is very advantageous. Indeed, thanks to the internal threaded part of the connection piece, it is possible to secure a threaded male part of suitable dimensions, for example a threaded rod in the preferred case where the connection part is tubular, by simply screwing it and quickly in the threaded internal part. In particular, it can thus be used an anchoring device which comprises a rod

- 8 - threaded in a first end part fixed to means of suspension and / or attachment to the construction arranged in a second end part. Thus, in the case of the mounting system as described according to the prior art, it is no longer necessary to bend a metal end bar on itself but simply to thread the end of this metal bar so that it is able to cooperate effectively with the connecting piece. In addition, this maneuver is very easy on site because it suffices for a worker to screw two parts together.

According to a preferred embodiment of the invention, the insert comprises a yoke comprising: - a female rod extending perpendicularly to the axis and consisting of the connecting piece; and - an orifice receiving the axle so as to provide a pivot connection between the yoke and the axle in the cavity.

This embodiment explains a preferred mechanical coupling between the axis and the connecting piece, the latter forming an integral part of a yoke intended to receive the axis to produce the pivot connection (that is to say a connection with a degree of freedom, this being the rotation of the yoke around the axis). Said orifice is preferably bordered by a symmetrical U-shape of a plate of the yoke, the female rod being held between the two branches of the U by welding. It is advantageous to use a screed as described because it is fairly easy and inexpensive to manufacture. Other embodiments of the connecting piece and its mechanical coupling with the axis are possible within the scope of the invention. For example, the connecting piece can be a nut or a threaded female sleeve preferably welded to such a U-shaped plate.

In the context of this document, a "constituent element of a construction" refers to a part of a construction, for example, a part of a wall, a wall, a block, a panel, etc. Preferably, it is a facade panel intended to be arranged and / or hung and / or suspended on and / or facing a facade of a support structure, for example, a wall of a

- 9 -

building.

Such a facade panel extends essentially over a surface defining this facade, and has a thickness which is defined and measured perpendicular to the facade, preferably at least 3 centimeters to ensure sufficient space to arrange and / or insert the insert according to the invention.

A "face" of a facade panel designates a surface of this panel extending parallel to the facade, and a "slice" of a facade panel designates another surface of this panel extending essentially perpendicular to the facade .

A facade panel preferably comprises two faces: a so-called "interior" face facing the support structure, generally invisible externally (therefore for an observer outside the building), and a so-called "exterior" face opposite the interior face. , visible from the outside.

The constituent element of the construction in question preferably consists of a cast and solidified construction material so that, during its manufacture, the insert is placed in a mold in which this construction material is poured.

Preferably, the latter is a concrete.

In the context of this document, the “construction” for which said element is intended is arbitrary.

It may for example be a building with or without a storey, a dam, a monument, etc. In the context of this document, a "box" preferably refers to a rigid container delimiting a cavity. suitable for accommodating goods, objects, various products.

It can be made of any material, for example, wood, cardboard, metal, plastic, ... and / or a combination of these.

The term "cavity" preferably refers to an interior space of a solid body, in this case preferably, the box.

The term "box" should also be interpreted as a means of defining the cavity when producing the building block.

In particular, any box which defines a cavity at least partially, so as to make possible the design of a constituent element of the construction is within the scope of the present invention.

It is for this reason in particular that it is not necessary for the cavity to be completely delimited by the box.

It may be sufficient to consider

- 10 - a box which includes a few faces in order to be able to design a constituent element of the construction.

In the context of this document, an "axis" is preferably a mechanical axis, that is to say an elongated mechanical part making it possible to rotate another mechanical part on itself and / or to assemble parts together. mechanical. The axis is preferably metallic and / or cylindrical. In particular, the axis is preferably a rod and / or a bar. It preferably passes through the box on either side through two opposing holes in it. Advantageously, the use of such an axis is easy and inexpensive in the context of the invention. Its manufacture is also easy and can be carried out in a chain by cutting a very long metal cylinder.

The use, in this document, of the verb "to understand", its variants, as well as its conjugations, can in no way exclude the presence of elements other than those mentioned. The use, in this document, of the indefinite article "UN", "a", or of the definite article "the", "the" or "| ", To introduce an element does not exclude the presence of a plurality of these elements.

According to several preferred embodiments of the invention, the insert comprises a load-taking support capable of supporting and / or maintaining at least one metal bar on the outside of the cavity. This load take-up support is preferably fixed to the axle and / or to the box. It plays an important role in the case where the constituent element of the construction is a facade panel, and where the insert is configured to accommodate a device for anchoring and / or fixing the facade panel to a facade of the building . In fact, in this case, the weight of the facade panel is transferred to the construction via the anchoring and / or fixing device and via the insert. It is therefore important that the weight of the facade panel is transferred optimally to the insert, more precisely to the axis and to the connecting piece. To this end, use is made of metal bars which are supported and / or mechanically coupled by the axis via the load recovery support, to advantageously take the weight of the

- 11 - panel optimally according to the extension of these metal bars in the building block towards the axis. Such metal bars advantageously make it possible to take up a significant weight of a facade panel even for a facade panel of low thickness. In order to be able to take up this load from the facade panel (and / or any constituent element of a construction which would be hung and / or suspended and / or fixed to a support structure by means of the insert according to the invention) , it is therefore necessary to provide an insert advantageously provided with such a support for taking up the load.

The metal bars preferably form a sealing reinforcement for the constituent element of the construction. They are preferably high adhesion bars.

Preferably, this load take-up support comprises at least one plate fixed to the axis and / or to the box in which at least one orifice is made to accommodate a metal bar on the outside of the cavity (and / or to the box. ). More preferably, each (such, at least one) plate extends perpendicular to the axis and comprises: a top portion extending around the axis and comprising a central orifice through which the axis passes. ; - two feet which extend in transverse directions from the top portion, beyond the cavity, and which each include an end hole to accommodate a metal bar.

Advantageously, the manufacture of such a plate is easy and inexpensive. It can be done, for example, by cutting a shape out of a large plate of material. Preferably, this material, that is to say that constituting each plate, is metallic. It is preferably the same material that constitutes the axis. Preferably, each plate is placed against a face of the box.

According to a first optional sub-embodiment, each plate is welded (and therefore fixed) to the axis, preferably at the level of the central hole.

_ Advantageously, it is then not necessary to carry out the weld all around

- 12 - of the central hole, and preferably, each plate is welded to the axis only by a welding point, so that the insert is in one piece and can be inserted (by example, cast) in a building material constituting the building block.

According to a second preferred sub-embodiment, the box comprises at least one lateral protuberance which preferably extends outwardly from an outer face of the box, preferably of cylindrical shape, and each plate comprises a fitting orifice to connect the plate against the box by interlocking the lateral protuberance in the interlocking hole of the plate, so that the insert is in one piece and can be inserted (for example, cast) in a building material constituting the building block. In the preferred case where the box is made of a plastic material, each lateral protuberance preferably passes completely through an engagement orifice of a plate, one end of the lateral protuberance then being heated and / or melted, and then pressed. against the plate so as to form a rivet which ensures a good fixing of the plate against the box (without the need to weld the plate with the axis as proposed in the first sub-embodiment). This has the advantage that a less skilled worker (not able to weld, for example) can easily perform this assembly of each plate with the shaft and the box during the manufacture of the insert. In addition, this prevents too much heat (for example from welding) near a plastic box which could melt.

The specific shape of each plate according to the aforementioned more preferred embodiment is very particularly adapted to allow an optimal transmission of internal forces from the constituent element of the construction to the axis (then to the connecting piece, then to a anchoring and / or fixing device secured and / or mechanically coupled to this connecting piece) by means of metal bars which pass through said central and lateral orifices, and this while avoiding the transmission of parasitic forces. The portion of

- 13 - vertex secures the plate with the axis for the transmission of these internal forces, while the two feet extend in directions which are specifically determined to take up these internal forces according to the components of predetermined forces.

Preferably, a first of these directions is vertical and perpendicular to the axis, while a second of these directions forms an angle between 40 and 60 °, preferably around 50 °, with the first of these directions.

The load take-up support preferably comprises two such plates according to the invention which are similar being arranged symmetrically on either side of the cavity (and / or of the box, and / or against the box). Thus, the loads and forces internal to the constituent element of the construction can be taken up and transmitted to the axis in a symmetrical and balanced manner.

The present invention also provides a constituent element of a construction, preferably a facade panel of the construction, comprising an insert according to the invention.

All of the preferred embodiments and all of the advantages of the insert according to the invention are transposed mutatis mutandis to the present element.

Preferably, the element is formed from a cast and solidified construction material such as concrete, the insert being previously placed in a location (for example, a formwork and / or a mold) in which this construction material is poured, then drowned in the latter.

Preferably, an edge of the element borders the box and / or the cavity of the insert, which allows easy access to the cavity on site, for example by opening and / or breaking the box.

Preferably, reinforcing bars (metal) are also placed beforehand in this location and then embedded in the construction material.

When the latter is concrete, the element then consists of so-called “reinforced” concrete and comprises an insert according to the invention.

According to the preferred embodiment where the insert comprises a load-taking support, the element preferably comprises at least one metal bar supported by the load-taking support.

Each such bar

- 14 - metal is preferably part of the set of reinforcing bars (to form reinforced concrete, for example) when the element includes it.

Thus, part of the element's rebars are used to transmit loads from the element to the axis via the plates of the load bearing bracket.

As explained above, the metal bars supported by the load-taking support are preferably embedded in a cast and solidified building material constituting the constituent element of the construction.

Preferably, according to the embodiment of Pinsert for which the load recovery support comprises two plates each comprising a top portion and two feet as described in this summary, the metal bars comprise: an axial metal bar s 'extends parallel to the axis and which passes through the end openings of one of the feet of each plate; - two metal gravity bars, each of which comprises two parallel straight portions which extend perpendicular to the axis, and a curved portion which connects the two straight portions so as to give a U-shape to each metal gravity bar, the curved portion of a first of the metallic gravity bars passing through the extremal orifice of the other of the feet of one of the plates, and the curved portion of a second of the metallic gravity bars crossing the extremal orifice the other of the feet from the other of the plates.

The metal bars thus arranged are maintained symmetrically allowing an optimal and homogeneous transmission of internal forces to the element according to a decomposition of forces into components parallel and perpendicular to the axis, and preferably according to the directions of extensions. of the faces of [element when it constitutes a facade panel.

Finally, the present invention also provides a kit comprising: - an element constituting a construction according to the invention, and - an anchoring part to cooperate with the connecting part.

All the preferred embodiments and all the advantages of the insert and of the element according to the present invention translate mutatis mutandis to the kit.

According to a particular embodiment, the anchoring part is a mounting system.

Preferably, the anchoring piece is configured to fix and / or support the element to / on the construction.

Preferably, the anchoring part comprises: e a first end part to cooperate with the connecting part so as to be secured to the latter; e a second end part configured to be suspended and / or fixed to a facade of the building.

The second end part is preferably a plate.

More preferably, when the connection piece comprises a threaded internal part, the first end part is a threaded rod capable of being screwed into the connection piece.

Thus, the anchoring device can be attached very easily and quickly to the element via the insert, to fix and / or support the element to / on the construction.

The assembly made up of the insert and this anchoring piece is called the “hanger”. Brief description of the figures Other characteristics and advantages of the present invention will become apparent on reading the detailed description which follows, for the understanding of which reference is made to the appended figures among which: FIG. 1A illustrates a three-dimensional schematic view of a insert according to a preferred embodiment of the invention; - Figure 1B illustrates a three-dimensional schematic view of the insert of Figure 1A comprising metal bars supported by a load recovery support; - Figure 2 illustrates a schematic side view of the insert of Figure 1A; - Figure 3 illustrates a schematic rear view of the insert of Figure 1A;

Detailed Description of Particular Embodiments of the Invention This part presents a detailed description of preferred embodiments of the present invention. The latter is described with particular embodiments and references to figures but the invention is not limited by them. In particular, the drawings or figures described below are only diagrammatic and are not limiting. The drawings of the figures are not necessarily to scale. Like elements are generally denoted by like references in the figures. In the context of this document, identical or similar elements may bear the same references. The presence of reference numbers and / or letters in the drawings cannot be considered as limiting, including when these numbers or letters are indicated in the claims.

The X, Y and Z references shown in Figure 1B correspond to geometric landmarks of three-dimensional space used to comment and / or view properties of embodiments of the invention. Thus, according to this figure, the axis 4 of the insert 1 according to this embodiment of the invention is arranged horizontally parallel to the axis X, the tubular connecting piece 31 extends in a direction perpendicular to the axis 4 A so-called “vertical” direction refers to a direction parallel to the Z axis shown, which according to this embodiment is preferably a direction parallel to that of the force of gravity.

The terms “first” and “second” are used in the context of this document exclusively to differentiate different elements, without implying order between these elements.

Figures 1A, 2 and 3 show several schematic views of an insert 1 according to a preferred embodiment of the invention. The insert 1 comprises a closed plastic box 2 delimiting a cavity 22. The box 2 comprises

- 17 -

a breakable outer wall 21 and designed to be broken with a construction tool, so as to be able to access the cavity 22 from the outside of the box 2. The box 2 also includes two opposing holes 23.

The insert 1 comprises a mechanical axis 4 passing through the cavity 22 and the box 2, through the two orifices 23 thereof.

Axis 4 passes through box 2 in a lower part along the Z axis of the latter.

The insert 1 comprises a yoke 3 comprising a symmetrical plate 34, cut mainly in a U shape, a lower part of this plate (corresponding to the hollow of the U shape) having an annular shape receiving and being traversed by axis 4 so to achieve a pivot connection between the yoke 3 and axis 4 in the cavity 22. The center of the annular shape defines an orifice 33 which is therefore crossed by the axis 4. The yoke 3 is provided with a connecting piece 31 arranged symmetrically between and welded to two parallel portions of the yoke plate 34 (corresponding to the U-shaped branches). In the illustrated configuration, the connecting piece 31 is arranged completely in the cavity 22. It is able to rotate (within the limits of a certain angular opening) in the cavity 22 around the axis 4 thanks to the pivot connection.

The connecting piece can be male or female, and capable of making an arbitrary connection with a mechanical part, the latter preferably being an anchoring device.

In the case of the insert 1 shown, the connecting piece 31 is a female rod of the yoke 3 extending perpendicularly to the axis 4. It therefore comprises a threaded internal part 32, suitable for screwing a rod ( male) threaded, and therefore preferably a threaded rod of an anchoring device.

The screwing manipulation is particularly simple and quick to perform on site once the box 2 is open, in particular because the connection piece 31 rotates around the axis 4, and therefore the orientation of the connection piece 31 can be adjusted to facilitate this manipulation as well as the subsequent use of the anchoring device.

As illustrated in Figure 1B, the direction of extension of the connecting piece 31 forms an angle 6 with the vertical direction Z.

This angle typically varies by about

180 ° because the rotational movement of the connecting piece 31 around the axis

- 18 - 4 is bounded by parts of the box 2 when the wall 21 is removed. There is an angular opening for the angle 6 around 0 ° such that the connecting piece 31 is arranged completely in the cavity 22. There is a critical value of the angle 6 such that the connecting piece 31 is just pressed against the wall. 21 (or stops at the opening replacing the wall 21 if it has been broken) and such that for any value of the angle greater than this critical value, a minor end portion of the connecting piece 31 s 'extends outside the cavity 21 (if the wall 21 has previously been broken so as to form an opening as explained in the summary).

Linsert 1 also includes a load recovery support provided with two plates 5 arranged symmetrically on either side of box 2, against box 2, similar to ears. These plates 5 extend in planes parallel to each other and parallel to the plane in which the connecting piece 31 is able to move in rotation about the axis 4 (although it can be locked in rotation in a defined position, for example by internal lateral reinforcements of the box 2, during its delivery to the site), these planes all being perpendicular to the axis 4. The plates 5 are cut to have the specific shape illustrated comprising a top portion 5A (referenced in FIG. 2) annular through which the axis 4 passes at its center (defining a central orifice 53 of the top portion 5A) and blocked at the level of the axis 4 by a rivet. This rivet is preferably formed by a cylindrical lateral protuberance of the box 2 passing through an engagement hole 54 of the plate 5. Each plate 5 also comprises two feet 5B and 5C (referenced in FIG. 2) which s' extend in transverse directions from the crown portion 5A, outwardly to and beyond the cavity 22, so that it is possible to mechanically support and / or couple vertical bars 61, 62 (according to the Z axis) and horizontal (along the X axis) at the end of these feet 5B, 5C without intercepting the box 2 (because the feet move far enough away from the box 2 in said directions), these bars then being able to s' extend in a construction material constituting a constituent element of a construction provided with the insert 1. In order to

- 19 - carrying out this support and / or mechanical coupling of bars 61, 62 as illustrated in FIG. 1B, each of the feet 5B and 5C is pierced with an end hole 52 and 51 respectively capable of accommodating such bars 61 and 62. More specifically, one of the bars 61 is an axial metal bar which extends parallel to axis 4 and which passes through each of the end openings 52 of the feet 5B of each plate 5, and two other bars 62 are metal bars. gravity essentially folded in the middle into two straight parallel portions so as to give them a U-shape, each of these bars 62 being carried gravitationally by the foot 5B of one of the plates 5 passing through an extremal orifice 51. This the latter is preferably oblong to facilitate the insertion of the bars 62. The bars 61 and 62 are preferably metallic with high adhesion in order to efficiently transmit the internal loads and / or forces of a constituent element of a construction provided. from insert 1 to axis 4 via the load recovery support.

FIG. 4 illustrates a kit according to one embodiment of the invention. This kit includes an element 7 constituting a construction consisting of a facade panel of the construction. The latter comprises an inner face 74A and an outer face 74B, and two edges, the upper edge 75 having been referenced. This facade panel will be fixed to the construction by means of an anchoring device 8 included in the kit. For this, the front panel includes the insert 1 previously discussed. This has been embedded in a building material 71, preferably concrete, constituting the facade panel, so that the wall 21 extends the inner face 74A, thus being visible to a construction worker. The insert 1 is also arranged in height (along the Z axis) in an upper part of the facade panel because it is at this location that the anchoring device 8 must be secured to support and / or fix. the facade panel to construction. To obtain such an element 7, it suffices to prepare a mold and / or a formwork in which the insert 1 and several metal bars 72, 73 are arranged, vertically and horizontally, so as to form a grid, some of these crossing bars. in the extremal openings 51 and

- 20 - 52 of the plates 5 of the insert 1, so as to define the metal bars 61, 62 previously introduced. Once this construction has been carried out, concrete is poured into the mold and / or formwork, thus forming the reinforced concrete facade panel provided with the insert 1. The anchoring device 8 comprises a threaded metal rod 82 so as to be able to easily screw one of its end portions 81 (forming a first end part of the anchoring device 8) into the threaded internal part 32 of the tubular connection part 31. The other end portion of this threaded metal rod 82 is fixed to a second end part 83 of the anchoring device 8 which is configured to be suspended and / or fixed to a facade of the building. Such a second end part 83 is known to a person skilled in the art, in particular for a mounting system, and preferably consists of a plate. However, the first end part 81 which is in the form of an end portion of a threaded rod differs from the prior art and allows rapid and effective attachment of the anchoring device 8 to the front panel via the insert 1. In addition, since the bars 61, 62 are mechanically coupled to the insert 1, they allow an advantageous transmission of internal loads and / or forces from the facade panel to the building through the device of anchor 8 and insert
