Description

The present invention relates to construction assemblies intended for the external faces of buildings. In particular, the present invention relates to the field of fixing a double-skin cladding on the structure of such a building.

In a known manner, real estate buildings can be thermally and / or acoustically insulated by means of suitable construction elements, such as double-skin cladding. These double-skin cladding conventionally comprise at least one interior skin consisting of at least one interior plate, fixed to the building concerned, and at least one exterior skin attached and attached to this interior skin. A thermally and / or acoustically insulating panel is interposed between the inner plate of the inner skin and the outer skin in order to provide thermal and / or acoustic insulation of the building.

The inner skin of a double-skin cladding also comprises a plurality of fixing wings which extend transversely to the inner plate and on which are fixed fixing tabs which make it possible to connect the outer skin to the inner skin. More particularly, these fixing lugs are fixed to the upper faces of the fixing flanges, that is to say the faces of these fixing flanges facing towards the sky when the double-skin cladding is mounted on the building concerned. These fixing wings are different depending on the supplier. Furthermore, the upper faces of these fixing wings can have ribs of different sizes, shapes and positions. These structural differences require the manufacture of as many different fixing brackets as there are fixing wings, which increases the production costs of these fixing brackets and complicates the assembly operations.

The present invention aims to resolve at least this drawback by proposing a fixing lug adaptable to the majority of fixing wings currently on the market, thus making it possible in particular to achieve economies of scale.

An object of the present invention thus relates to a fixing lug configured to connect an inner skin to an outer skin of a construction element, the fixing lug comprising at least one main wall from which emerges at least one fixing wall and at least one fixing wall. minus one force-absorbing wall, the main wall comprising at least one area for fixing to the inner skin, the fixing wall being configured to be made integral with the outer skin, the main wall extending mainly in a first plane , the force-absorbing wall extending mainly in a second plane, the fixing wall extending mainly in a third plane, the first plane being transverse to the second plane and to the third plane.

In the present invention, the inner skin is a metal sheet which delimits the peripheral internal volume of a building produced using the construction element. The outer skin is an external cladding exposed to the external environment of the building and responsible for protecting the insulation from external aggressions such as rain, wind, etc.

According to one characteristic of the present invention, the first plane in which the main wall extends is perpendicular to the second plane in which the force-absorbing wall mainly extends. In other words, according to this characteristic of the present invention, an angle formed between the first plane and the second plane is equal to or substantially equal to 90 °.

According to the invention, the force-absorbing wall comprises a fixing surface configured to come into contact with the inner skin. Optionally, the fixing surface of the force-absorbing wall can be fixed to the inner skin.

Optionally, the first plane in which the main wall of the fixing lug is inscribed may be perpendicular to the second plane in which the force-absorbing wall is inscribed and to the third plane in which the fixing wall is inscribed. In other words, it is understood that the third plane and the second plane are then parallel, that is to say that the force-absorbing wall and the wall of the fixing lug are mutually parallel.

According to the invention, the main wall, the fixing wall and the force-absorbing wall can form a one-piece assembly. In other words, the fixing lug forms a single assembly which cannot be separated without causing deterioration of the main wall, of the fixing wall and / or of the force-absorbing wall. Alternatively, the main wall and the fixing wall form a one-piece assembly, that is to say an assembly which cannot be separated without causing deterioration of the main wall or of the fixing wall, the return wall. force being, according to this alternative, attached to the assembly formed by the main wall and the fixing wall. According to yet another alternative, the fixing wall, the main wall and the force-absorbing wall are all three distinct and secured to each other, after their manufacture.

According to the invention, the fixing zone of the main wall extends beyond the force-absorbing wall, away from the fixing wall. The force-absorbing wall makes it possible to reduce the forces supported by the main wall of the fixing lug, and more particularly by the fixing zone of this main wall of the fixing lug, which then makes it possible to reduce the dimensions of this fixing zone of the main wall without reducing its mechanical strength properties. This reduction in dimensions resulting from the presence of the force-absorbing wall makes it possible to design a fixing lug which does not interfere with the ribs and other specific features of the different types of fixing wing.

According to an exemplary embodiment of the present invention, the fixing surface of the force-absorbing wall extends in the second plane, at least on either side of the main wall. In other words, the fixing surface of the force-absorbing wall extends beyond the main wall, on either side of this main wall in a direction transverse to a main direction of extension of the wall. main. Advantageously, such a configuration can make it possible to make the fixing surface accessible, that is to say that the main wall does not obstruct this fixing surface, which facilitates the possible fixing of the force-absorbing wall. to the inner skin. Optionally, the main wall can include a first part which extends, mainly, in the direction of extension. main wall of the main wall, and a second part which extends, for the most part, in a direction perpendicular to the main direction of extension of the main wall and which fits in the foreground, the fixing surface of the wall of absorption of force extending on either side of the first part and the second part forming the fixing zone.

According to another exemplary embodiment of the present invention, the fixing zone of the main wall extends in the first plane, at least on either side of the force-absorbing wall.

According to yet another exemplary embodiment of the present invention, the force-absorbing wall extends in the second plane, at least on either side of the fixing zone of the main wall.

The present invention also relates to a construction assembly intended for a building, comprising at least one inner skin comprising at least one inner plate intended to be fixed to a support of the building, the construction assembly comprising at least one outer skin, the plate interior and the exterior skin delimiting an internal space in which is housed at least one insulation panel, the interior skin being connected to the exterior skin by at least one fixing tab according to the invention. Advantageously, a plurality of fixing tabs according to the invention makes it possible to connect the inner skin and the outer skin. For example, the insulation panel can be formed from mineral wool or wood wool. This insulation panel can also be in the form of a roll that the technician will then have to cut into panels to integrate them into the construction element according to the invention.

According to one characteristic of the invention, the inner skin comprises at least one fixing wing which comprises at least one flank which extends transversely to the inner plate in the direction of the outer skin and the fixing wing comprises at least one lip of return. According to the invention, this return lip extends mainly in a plane transverse to a plane in which the sidewall is predominantly inscribed.

According to the invention, the fixing zone of the main wall of the fixing lug is fixed to an upper face of the side of the fixing wing of the inner skin, this upper face being turned away from the lip of the inner skin. return. In other words, the fixing zone of the main wall is fixed on a face of the side of the fixing wing which faces the sky when the construction element is assembled on the building concerned. The force-absorbing wall of the fixing lug is itself fixed to the return lip of the fixing wing of the inner skin.

According to the invention, at least one rib is provided on the upper face of the side of the fixing wing of the inner skin, this upper face being turned away from the return lip, a distance measured between the rib and a free edge of the fixing flange, located at the intersection of the sidewall and the return lip, being greater than a dimension of the fixing zone of the main wall of the fixing lug measured parallel to the direction of main extension of the main wall.

According to an example of application of the present invention, a secondary framework can be interposed between the fixing lug and the outer skin. In other words, the fixing lug is then fixed on the one hand on the inner skin, and on the other hand on the secondary framework, this secondary framework for its part being fixed to the outer skin. More particularly, according to this example, the secondary framework is fixed to the fixing wall of the fixing lug and the outer skin is itself fixed to the secondary framework. For example, this secondary framework may consist of at least one metal section, advantageously of a plurality of metal sections, distributed along the construction element. For example, these metal profiles have a Z or Omega shape.

The invention finally relates to a method of assembling a construction assembly according to the invention, comprising at least a first step of fixing an interior plate of an interior skin on the support of the building, at least a second step for fixing a fixing tab according to the invention on the inner skin, at least a third step of fitting the insulation panel and at least a fourth step of fixing an outer skin on the fixing lug or on a secondary framework, the second step comprising at least a first sub-step of positioning the force-absorbing wall of the fixing lug in contact with the return lip of the 'fixing wing and / or at least a second sub-step of fixing the fixing zone of the main wall of the fixing lug on the fixing wing of the inner skin and / or at least a third sub-step for fixing the force-absorbing wall on the return lip of the inner skin fixing wing. More precisely, the outer skin or the secondary framework is fixed to the fixing wall of the fixing lug.

An internal skin therefore forms an internal skin of the building, while an external skin forms an external skin of the building, at least one insulation panel and one fixing lug according to the invention being arranged between these two skins. Furthermore, a so-called "lower" element refers to an element facing the ground when the construction element is mounted on the building and a so-called "upper" element corresponds to an element facing the sky when the building element is mounted on the building. construction element is mounted on the building.

The figures 1 to 7 schematically illustrate a perspective view of a fixing tab 100 intended to connect the inner skin to the outer skin, according to various embodiments of the present invention. We will first describe the characteristics common to all of the exemplary embodiments illustrated before detailing the distinctive features of each of these exemplary embodiments.

According to any one of the embodiments illustrated on the figures 1 to 7 , this fixing lug 100 comprises at least one main wall 110, a fixing wall 120 and a force-absorbing wall 130.

According to the invention, the main wall 110 extends in a main direction of extension D1 and extends in a first plane P1 transverse to a second plane P2 in which the force-absorbing wall 130 extends. an exemplary embodiment illustrated here, the first plane P1 is also transverse to a third plane P3 in which the fixing wall 120 extends. According to the invention, at least part of the main wall 110 and at least part of the force-absorbing wall 130 are configured to be fixed to the inner skin and the fixing wall 120 is for its part intended to achieve the fixing of the outer skin. According to the example illustrated, the first plane P1 is more particularly perpendicular to the second plane P2 and to the third plane P3. In other words, according to this example, the fixing wall 120 and the force-absorbing wall 130 are mutually parallel and both perpendicular to the main wall 110 of the fixing lug 100.

Furthermore, it is noted that a portion of the main wall 110 extends beyond the force-absorbing wall 130, in the first plane P1, away from the fixing wall 120. As will be more Amply detailed below, this portion of the main wall 110 forms an attachment zone 111 intended to be attached to the inner skin. According to the examples illustrated, at least one orifice 112 is formed in this fixing zone 111, this orifice 112 being configured to receive at least one first fixing means, such as for example a screw, a nail or a rivet.

As will be more fully detailed below, a lower face 113 of the fixing zone 111 of the main wall 110 is configured to come in contact with a fixing wing of the inner skin of said construction element, an outer face 121 of the fixing wall 120 is intended to come into contact with the outer skin, or a secondary framework and an inner face 133 of the force-absorbing wall 130 is for its part configured to come into contact with the fixing wing of the inner skin of the construction element.

According to a first example of the present invention illustrated on figure 1 , the fixing lug 100 forms a one-piece assembly, that is to say a single assembly which cannot be separated without causing deterioration of the main wall 110, of the fixing wall 120 and / or of the return wall force 130.

According to a second exemplary embodiment of the present invention illustrated in figure 2 , the fixing lug 100 is formed of a first part 101 which comprises at least a portion of the main wall 110 and the fixing wall 120 and of a second part 102 which in turn comprises at least another portion of the main wall 110 and the force-absorbing wall 130. As shown, the first part 101 and the second part 102 are fixed to one another. More particularly, the main wall portion 110 of the first part 101 is fixed to the main wall portion 110 of the second part 101 by fixing means such as for example screws, rivets or a weld bead. For example, the first part 101 and the second part 102 are independently machined, then independently shaped, for example by bending, before being fixed to one another. Before the folding step, it is understood that the first part 101 has a rectangular shape, or substantially rectangular, and that the second part 102 has a T-shape. It is understood that these are only examples of embodiment of the invention and that any other means making it possible to make the main wall 110, the fixing wall 120 and the force-absorbing wall 130 integral can be envisaged without departing from the context of the present invention.

It is also noted that, according to the first or the second exemplary embodiment illustrated, respectively on the figures 1 and 2 , the return wall force 130 extends beyond the main wall 110, along a direction D2 transverse to the main direction of extension D1 of the main wall 110 and which is in the second plane P2. More particularly, this force-absorbing wall 130 extends beyond the main wall 110 along the direction D2, that is to say in the second plane P2, on either side of this main wall 110. The force-absorbing wall 130 thus has a fixing surface 131 distributed on either side of the main wall 110 and intended to be fixed to the inner skin. To this end, the fixing surface 131 has at least one hole 132 intended to receive a fixing means, such as for example a screw, a nail or a rivet. According to the example illustrated, the fixing surface 131 has two holes 132 intended for fixing this force-absorbing wall 130 on the inner skin, these holes 132 being distributed on either side of the main wall 110.

The figure 3 illustrates a variant of the first exemplary embodiment of the present invention. This variant of the first exemplary embodiment differs from the latter in particular in that the main wall 110 has a T-shape. In other words, the main wall 110 comprises at least a first portion 114 which extends in the direction of extension. main D1 of the main wall 110 and at least one second portion 115 which extends in a direction D3 perpendicular to the first direction D1 and which is inscribed in the first plane P1. According to this variant of the first embodiment of the present invention, the force-taking wall 130 extends on either side of the first portion 114 of the main wall 110. More particularly, the force-taking wall force 130 comprises at least a first part 134 and at least a second part 135 distributed on either side of the first portion 114 of the main wall 110. As illustrated, the first part 134 and the second part 135 forming the force-absorbing wall 130 emerge, both from an edge 116 of the second portion 115 of the main wall 110 facing the first portion 114 of this main wall 110, and extend in the second plane P2 such that previously defined.

The other characteristics are common with the characteristics of the first exemplary embodiment illustrated on figure 1 , so that the description given above applies mutatis mutandis to this third exemplary embodiment.

The figure 4 illustrates a third embodiment of the fixing lug 100 according to the invention. This third exemplary embodiment differs from the exemplary embodiments which have just been described in that the force-absorbing wall 130 extends on either side of the fixing zone 111 of the main wall 110. Thus, similarly to what has just been described with reference to the figure 3 , the force-absorbing wall 130 comprises the first part 134 and the second part 135, distributed on either side of the fixing surface 111. This third exemplary embodiment also differs from the exemplary embodiments described above, in that the portion of the main wall 110 forming the fixing surface 111 has a width 11 less than the width 12 of the rest of the main wall 110. The term "width of the portion of the main wall 110 forming the surface of attachment 111 ”and by“ width of the rest of the main wall 110 ”, a dimension of the object in question measured perpendicular to the main direction of extension D1 of the main wall 110 between two opposite edges of this object.

This third exemplary embodiment differs more particularly from the variant of the first exemplary embodiment which has just been described in that the first part 134 and the second part 135 of the force-absorbing wall 130 emerge from an edge 117 of the main wall 110 from which emerges the portion of the main wall 110 which forms the fixing zone 111. These two parts 134, 135 of the force-absorbing wall 130 both extend in the second plane P2 such that previously defined.

The figure 5 illustrates a variant of the third exemplary embodiment which has just been described. This variant differs from the third exemplary embodiment in that the first part 134 and the second part 135 of the force-absorbing wall 130 are linked together. In other words, the force-absorbing wall 130 extends both on either side of the fixing zone 111 of the main wall 110 and under this fixing zone 111, that is to say that 'a part of this force-absorbing wall 130 extends opposite the lower face 113 of this fixing zone 111. Thus the force-absorbing wall 130 according to this variant of the third exemplary embodiment has a U-shape, each of the branches of which emerge from the edge 117 of the main wall 110, from which also emerges the portion of the main wall 110 which forms the fixing zone 111, and of which a base , which connects the two aforementioned branches, extends in the direction D2 transverse to the main direction of extension D1 of the main wall 110 as defined above.

The figures 6 and 7 illustrate, respectively, a fourth exemplary embodiment and a variant of this fourth exemplary embodiment of the present invention.

As shown, this fourth exemplary embodiment and its variant differ from the examples which have just been described in that the fixing zone 111 of the main wall 110 extends on either side of the return wall. force 130, along the direction D2 transverse to the main direction of extension D1 of the main wall 110. In other words, the portion of the main wall 110 forming the fixing zone 111 here comprises at least a first part 118 and a second part 119 which are interconnected by the edge 117 of the main wall 110 from which emerges the force-absorbing wall 130. The variant of the fourth embodiment differs from the latter in that the first part 118 and the second part 119 of the portion of the main wall 110 are interconnected. Thus, the portion of the main wall 110 which forms the fixing zone 111 has a U-shape, each of the branches of which extends the rest of the main wall 110 and of which a base, which connects these branches, extends opposite the edge. 117 from which the force-absorbing wall 130 emerges.

It is also noted that, according to the fourth exemplary embodiment and its variant illustrated in the figures 6 and 7 , the fixing lug 100 comprises two orifices 112 distributed over each of the parts 118, 119 which form the fixing zone 111 and a single hole 132 is made in the force-absorbing wall 130. It is understood that it does not s 'acts only as exemplary embodiments and that any other arrangement of these holes and orifices can be envisaged without departing from the context of the present invention.

The fixing lug 100 according to the embodiments which have just been described can advantageously be in one piece, that is to say that the main wall 110, the fixing wall 120 and the force-absorbing wall 130 form a unique assembly which cannot be separated without causing the deterioration of at least one of these walls. Alternatively, the aforementioned walls can be produced independently of one another and then joined together to form the fixing lug 100 according to the invention.

The figure 8 partially and schematically illustrates an exemplary embodiment of a building element 200 according to the invention which comprises at least one inner skin 201 which comprises at least one inner plate 210 fixed to a support 209 of a building for which it is intended. 'building element 200, the building element 200 further comprising at least one secondary frame 221 and an outer skin 220, the outer skin 220 being fixed to the secondary frame 221. As schematically illustrated, the inner plate 210 is fixed to the support 209 by means of at least one fixing member 208, such as for example a screw, a nail or a rivet. The inner skin 201 and the outer skin 220 are stamped or press-formed metal bands and the secondary framework 221 is formed by a metal Z or omega profile. The inner skin 201 and the outer skin 220 are interconnected by means of at least one fixing tab 100 as has just been described and illustrated in the figures. figures 1 to 7 . More particularly, the example illustrated on figure 8 uses a fixing lug 100 according to the first embodiment described with reference to figure 1 , but it is understood that any of the exemplary embodiments described above could be used. The description given below thus applies mutatis mutandis, with the exception of structural differences, to all of these exemplary embodiments. According to the example shown on figure 8 , the fixing lug 100 is fixed on the one hand to the inner skin 201 and on the other hand to the secondary frame 221 on which the outer skin 220 is fixed. The support 209 on which the inner plate 210 is fixed is by example made of wood or metal, and forms a primary framework of the building. The interior plate 210 and the exterior skin 220 define, between them, an internal space 230 in which an insulation panel 240 is received.

This insulation panel 240 can be a thermal and / or acoustic insulation panel. Such an insulation panel 240 can thus be formed from any known material having thermal and / or acoustic insulation properties. It is for example a mineral wool or glass wool panel. It is understood that the term "panel" refers to the state in which the insulating material is when it is inserted into the internal space 230. In other words, provision may be made for the insulating material to be in the form of a roll as the technician will have to cut into panels to insert it into the internal space 230 of the building element 200 concerned.

According to the invention, the secondary framework 221 on which the outer skin is fixed is optional. In other words, according to an exemplary embodiment not illustrated here, the outer skin is directly fixed to the fixing lug, that is to say that, according to this example not illustrated, the outer skin is in contact with the fixing lug. .

The inner skin 201 also comprises at least one fixing wing 211 which comprises at least one flank 212 which extends transversely to a major extension plane of the inner plate 210 and at least one return lip 213 which extends mainly along a direction perpendicular to the sidewall 212, that is to say substantially parallel to the majority extension plane of the interior plate 210. This return lip 213 extends from a free edge 217 of the fixing flange 211 located at a intersection between the flank 212 and the return lip 213 and optionally comprises an oblique final portion 214 which extends from a point of the return lip 213 furthest from the free edge 217 of the fixing wing 211, in the direction of the inner plate 210. Finally, we note the presence of ribs 215 formed on an upper face 216 of the fixing wing 211, that is to say a face of this fixing wing 211 turned towards the sky when building element 200 th st fixed on the building concerned. Although not illustrated here, other ribs can also be produced on a lower face of the binding wing, that is to say a face of this binding wing opposite to its upper face, and which faces the floor when the fixing bracket is in position in the construction element. Advantageously, the ribs formed on the upper face of the fixing wing can be symmetrical to the ribs provided on the underside of this fixing wing. It is understood that this is only an exemplary embodiment and that other shapes can be envisaged for forming the fixing wing without departing from the context of the invention.

As previously mentioned, the fixing tab 100 according to the invention is fixed, on the one hand, to the secondary framework 221 and / or to the outer skin 220 and, on the other hand to the inner skin 201. More particularly , the fixing wall 120 of the fixing lug 100 is fixed to the secondary frame 221 and / or to the outer skin 220 and the main wall 110 of this fixing lug 110 is fixed to the side 212 of the fixing wing 211 of the inner skin 201. Thus, at least one first fixing means 300 makes it possible to make the secondary frame 221 and / or the outer skin 220 integral with the fixing wall 120 of the fixing lug 100 and at least a second fixing means 310 makes it possible to secure the main wall 110 of the fixing lug 100 to the side 212 of the fixing wing 211 of the inner skin 201.

Furthermore, it is noted that the force-absorbing wall 130 of the fixing lug 100 is at least resting against the return lip 213 of the fixing flange 211. More particularly, it is the inner face 133 of the fixing flange. this force-absorbing wall 130 which is in contact with the return lip 214. Advantageously and additionally, this force-absorbing wall 130 can be made integral, thanks to at least one third fixing means 320, of this return lip 213 of the fixing wing 211. The terms “makes it possible to make integral” must here be understood as the fact that the fixing means concerned passes through all of the elements made integral. Thus, for example, the first fixing means 300 passes through the secondary framework 221 and / or the outer skin 220 and the fixing wall 120 of the fixing lug 100, the second fixing means 310 passes through both the main wall 111 of the fixing lug 100 and the flank 212 of the fixing flange 211 of the inner skin 201 and the third fixing means 320 passes through both the force-absorbing wall 130 and the return lip 213 of the fixing wing 211.

With reference to what has been described above, it is understood that at least one second fixing means 310 more specifically makes it possible to secure the fixing zone 111 of the main wall 110 to the fixing flange 211 of the inner skin 201. and that at least one third fixing means 320 allows for its part to secure the fixing surface 131 of the force-absorbing wall 130 to the return lip 213 of the fixing wing 211. According to the example illustrated here, two third fixing means 320 make it possible to secure the force-absorbing wall 130 to the return lip 213 of the fixing wing 211. When the fixing lug 100 used is produced according to the first or the second example embodiment, these two third fixing means 320 are distributed on either side of the main wall 110, that is to say on the sides thereof.

As illustrated, the fixing zone 111 of the main wall 110 is made integral with the upper face 216 of the flank 212 of the fixing flange 211, that is to say the face of this fixing flange 211 which carries the ribs 215 described above, so that the lower face 113 of this fixing zone 111 is arranged in contact with the upper face 216 of the sidewall 212. In order not to interfere with these ribs 215, the fixing zone 111 has a dimension d3, measured parallel to the main direction of extension D1 of the main wall 110, less than or equal to a distance d4, measured between one of the ribs 215 carried by the upper face 216 of the side 212 of the fixing flange 211 and the free edge 217 of this fixing flange 211. For example, the distance d4 can be measured between the free edge 217 of this fixing flange 211 and the rib 215 closest to this free edge 217. The load-absorbing wall 130 of the fixing bracket 100 pe rmits to reduce the force supported by the fixing zone 111 of the main wall 110 of this fixing lug 100, which makes it possible to reduce the proportions of the fixing lug 100 with respect to the known lugs, while ensuring mechanical retention optimum from outer skin 220 to inner skin 201.

The figure 9 illustrates, in the form of a flowchart, a method of assembling a construction element 200 according to the invention. This method comprises at least a first step E1 of fixing the inner plate of the inner skin on the support 209 of the building for which the element of construction 200 according to the invention. The assembly continues with the implementation of at least a second step E2 which aims to secure at least one fixing lug according to the invention on a fixing wing of the inner skin.

At least a third step E3 consists of the installation of the acoustic and / or thermal insulation panel. Optionally, the thermal and / or acoustic insulation panel may have a cutout suitable for receiving, at least, the fixing wing of the inner skin. Advantageously, this cutout can also be adapted to receive the fixing lug. For example, this cutout could be made in the thermal and / or acoustic insulation panel when the latter is made of rock wool. On the other hand, when the thermal and / or acoustic insulation panel is made of a glass leash, this panel may be devoid of any cutout. A fourth step E4 is aimed at fixing the outer skin on the fixing lug, whether or not via a secondary framework, which is the subject of the invention.

The second step E2 comprises at least three sub-steps SE21 and SE22, SE23 hereinafter referred to as “first sub-step SE21”, “second sub-step SE22” and “third sub-step SE23”.

Thus, the first sub-step SE21 consists in positioning the fixing lug so that the force-absorbing wall of this fixing lug is arranged in contact with the return lip of the fixing wing concerned. The second sub-step SE22 consists in securing the fixing zone of the main wall of the fixing lug on the upper face of this fixing wing, in particular by using the second fixing means as described above. The third sub-step SE23 consists in fixing the force-absorbing wall of the fixing lug on the return lip of the fixing wing of the inner skin, by the implementation of the two third fixing means as described above.

According to the invention, the second sub-step SE22 and the third sub-step SE23 are independent and provision may be made to carry out only one of the two without departing from the context of the present invention. Thus, according to a first embodiment, the second step E2 of the method of assembling the construction element according to the invention comprises the first sub-step SE21 and the second sub-step SE22, according to a second embodiment, the second step E2 of the method of assembling the construction element according to the invention comprises the first substep SE21 and the third substep SE23 and, according to a third embodiment, the second step E2 of the assembly method of the construction element according to the invention comprises the first substep SE21, the second substep SE22 and the third substep SE23, the second substep SE22 and the third substep SE23 can then be carried out in this order or in a reverse order without distinction.

The third step E3 consists in positioning the insulation panel in the internal space of the construction element. Where appropriate, this insulation panel must be positioned so that any cutout made in the latter is arranged opposite the fixing lug and the fixing flange. Finally, the fourth step E4 consists of the implementation of the first fixing means so as to fix the outer skin or the secondary framework on the fixing wall of the fixing lug.

The invention therefore proposes a simple and standardized means which makes it possible to assemble an outer skin to an inner skin so as to form a construction element providing thermal and / or acoustic insulation of a building to which it is fixed. It is understood that the invention is not limited to the means described and illustrated here and that it also extends to any equivalent means and configuration and to any technically operative combination of such means. In particular, the shape and arrangement of the fixing means described for fixing the fixing lug on the inner skin and on the outer skin can be modified without harming the invention insofar as they fulfill the functionalities described in the this document.
