    METHOD FOR MANUFACTURING AN INTERIOR WALL AND WALL
    INTERIOR OBTAINED
    Technical area :
    The present invention relates to a method for manufacturing an interior wall, in particular a cross wall, intended to be linked to an exterior wall of a building by at least one of its edges called the "joining edge".
    The invention also relates to the interior wall obtained by said manufacturing process.
    Prior art:
    In the general field of building construction, the dividing walls are interior walls, generally load-bearing, which form part of the structure of the building and ensure the bracing of the building, that is to say that they participate in the building stability both vertically and horizontally. These cross walls can be wall cladding and cast in place on site, prefab walls with full slab, prefab walls with lost formwork, masonry walls, etc. The invention relates to all types of known interior walls and in particular to prefabricated interior walls with integrated formwork. Furthermore, the thermal regulations in force have made it compulsory to limit the heat loss at the junction between the exterior walls and the interior walls and floor, either by insulation from the exterior of the building (ITE) or by interior insulation. of the building (ITI). The invention relates more particularly to thermal insulation implemented by the interior of the building (ITI).
    2017/5809
    BE2017 / 5809
    To ensure the bracing of buildings, the dividing walls are mechanically linked to the exterior walls or front walls of the building by one of their edges, also called strands. To date, there are several types of connection between the crosswalls and the facade walls, such as conventional connections and separate connections. Conventional connections in masonry or reinforced concrete are poured on site and produced according to the standards in force with continuous chaining thus ensuring a structural connection over the entire height of the connection between the exterior wall and the interior wall. However, these conventional connections do not include thermal bridge breakers and generate significant linear heat loss. In the case of dissociated connections, the cross wall is not structurally linked to the facade wall since a thermal insulator is continuously interposed between the interior wall and the exterior wall. Even if this solution makes it possible to resolve the linear heat losses of conventional connections, it is not satisfactory since it does not guarantee the structural connection between the cross wall and the front wall necessary to ensure the bracing of the building. Thus, this type of disconnected link does not meet seismic standards. In addition, this disconnected link generates weaknesses in terms of acoustics as well as risks of general ignition in the event of a fire.
    The publication FR 2 865 227 A1 proposes a thermal break system between two walls which can be respectively an exterior wall and an interior wall. It comprises insulation elements arranged between the two walls and separated by an interval for the passage of recovery reinforcements provided in a box of waiting reinforcements integrated in the exterior wall. Each insulating element comprises a plate of insulating material, protected laterally by profiles, and provided at its ends with a wedge for abutting against the return reinforcements and fixing means such as adhesive strips so that it can be fixed on the inside of the outside wall. These insulation elements are separate and not
    2017/5809
    BE2017 / 5809 integrated into the thickness of the interior wall during its manufacture, and therefore require complex and costly implementation.
    The technical solutions proposed in the publications FR 2 890 990 A1 and EP 2
    476 822 A1 also relates to thermal break systems between an external wall and a slab or a cross wall in which the insulation element is either integrated into the external wall, or interposed between the external wall and the cross wall, extending continuously over the entire height of the junction zone preventing any continuous mechanical and structural connection between the two walls and thus having all the drawbacks of a separate connection described above.
    Consequently, at the present time there is no solution making it possible to effectively limit the linear heat losses in the junction "façaderefend" in the case of thermal insulation by the interior of the building, in accordance with the thermal regulations in force, without degrading the structure of the building, nor fire safety and sound insulation.
    Statement of the invention:
    The present invention aims to overcome these drawbacks by proposing a method for manufacturing an interior wall incorporating thermal insulation making it possible to significantly reduce thermal bridges at the junction between the façade and the slit, in particular in the case of thermal insulation by he interior of the building, without degrading the mechanical stability or the structure of the building, making it possible to use it in seismic zones, while respecting the regulations relating to fire safety and acoustic insulation of the building.
    To this end, the invention relates to a method of manufacturing an interior wall of the kind indicated in the preamble, characterized in that means are integrated
    2017/5809
    BE2017 / 5809 for thermal insulation and reinforcement in the thickness of said interior wall during its manufacture, in the immediate vicinity and along said junction edge to create at least partially a thermal break between said interior wall and the exterior wall of the building with which it is intended to be linked, and in that said thermal insulation means are arranged in the thickness of said interior wall in a discontinuous manner along said junction edge to create gaps in which said connecting frames are positioned to mechanically and structurally link said interior wall to said exterior wall of the building when they are assembled.
    This process has the advantage of considerably reducing the linear heat losses from the facade-split junction from the inside of the building, while preserving a continuous mechanical and structural connection within this junction between the interior wall and the exterior wall. In addition, if the thermal insulation means do not completely cross the thickness of the interior wall, it can both meet fire safety standards since the solid part of the thickness of said wall forms a barrier against propagation flames and gases in the event of fire, as well as a sound barrier.
    It is of course possible to manufacture said interior wall directly on site by pouring a filling material into an appropriate formwork. In this case and before the pouring of said interior wall, the means of thermal insulation and the connection reinforcements are positioned in said formwork.
    Said interior wall can also be manufactured from a prefabricated wall made of solid slab. In this case and before the casting of a molding material in a formwork mold suitable for forming the solid slab, the means of thermal insulation and the connection reinforcements are positioned in said formwork mold.
    2017/5809
    BE2017 / 5809
    Preferably, said interior wall can be manufactured from a prefabricated wall with integrated formwork comprising two parallel walls, a first wall and a second wall, held at a distance by spacers to delimit an interior formwork capable of being filled with a filling material poured on site. In this case, one can proceed as follows: in a first step, at least said spacers, said thermal insulation means and said connecting frames are positioned in a suitable formwork mold, it is poured into said formwork mold a molding material to form the first wall of said wall; in a second step, a filling material is poured into another suitable formwork mold to form the second wall of said wall; and in a third step and before hardening of the second wall, the first wall is turned over above the second wall, making at least said spacers and said connecting plates penetrate into the fresh molding material of the second wall .
    In all embodiments, thermal insulation means will be chosen which extend over a height at most equal to the thickness of said interior wall.
    In the case of a prefabricated wall with integrated formwork, it is possible to choose thermal insulation means having a height less than the height of the spacers, and substantially equal to the thickness of the first wall plus the thickness of the internal formwork . In this case, during the first step of said method, it is possible either to fix said thermal insulation means directly in the formwork mold so that they pass through the thickness of said first wall, or to fix said insulation means thermal in said formwork mold by means of receiving supports so that they do not pass through the thickness of said first wall.
    2017/5809
    BE2017 / 5809
    One can also choose thermal insulation means having a height greater than the height of the spacers, and substantially equal to the thickness of the two walls plus the thickness of the interior formwork. In this case, during the first step of said method, said thermal insulation means can be fixed directly in said formwork mold so that they pass through the thickness of said first wall, and during the third step, l 'The spacers, the connection plates and said thermal insulation means can be made to penetrate the fresh molding material of the second wall so that the latter also pass through the thickness of said second wall.
    To form said thermal insulation means, it is possible to use a single thermal breaker disposed in parallel with said junction edge and having a length less than that of the junction edge of said wall to provide at its ends two intervals, or several thermal breakers aligned in a row parallel to said junction edge and spaced from each other to provide said interval between two consecutive thermal breakers.
    Each thermal breaker can be produced from at least one insulating bar, which may or may not be attached to a receiving support, said thermal breaker and / or said insulating bar may also have fire-resistant properties.
    For this purpose, the invention also relates to an interior wall of the kind indicated in the preamble, characterized in that it is obtained from the manufacturing process as defined above, and in that it comprises means for thermal insulation and connecting reinforcements integrated into the thickness of said wall during its manufacture, in the immediate vicinity and along said junction edge intended to create at least partially a thermal break between said interior wall and the exterior wall of said building when linked to the latter, said thermal insulation means being arranged in the thickness of said wall in a discontinuous fashion along said junction edge to create gaps in which are
    2017/5809
    BE2017 / 5809 positioned said connecting frames intended to mechanically and structurally connect said interior wall to said exterior wall of the building when they are assembled.
    Said interior wall may consist of a wall poured directly on site integrating said thermal insulation means and said connecting reinforcements, or a prefabricated wall in solid slab also integrating said thermal insulation means and said connecting reinforcements.
    It can also consist of a prefabricated wall with integrated formwork comprising two parallel walls, a first wall and a second wall, held at a distance by spacers to delimit an interior formwork capable of being filled with a filling material poured on site integrating said thermal insulation means and said connecting reinforcements.
    In all the variant embodiments, the thermal insulation means can extend over a height at most equal to the thickness of said wall.
    In the case of a prefabricated wall with integrated formwork, these thermal insulation means can extend over a height at least equal to the thickness of a wall of said wall plus the thickness of the interior formwork of said wall. They can, as required, cross the first wall and the second wall to be flush with the exterior faces of said wall, or pass through only one of the walls to be flush with the corresponding exterior face of said wall.
    These thermal insulation means may comprise a single thermal breaker disposed parallel to said junction edge and having a length less than that of the junction edge of said wall to provide at its ends two intervals. Preferably, they include several breakers
    2017/5809
    BE2017 / 5809 thermal aligned in a row parallel to said junction edge and distant from each other to provide an interval between two consecutive thermal breakers.
    Each thermal breaker can comprise at least one insulating bar, fixed or not to a receiving support, and also comprising fire-resistant properties.

    Illustrations of the invention and different ways of carrying it out:
    With reference to the figures, the invention relates to a method of manufacturing an interior wall 10, 20, 30 for a building 1 making it possible to integrate thermal insulation means 40 at the junction of “exterior wall-interior wall” commonly called “facade-splitting” junction, regardless of the construction technique of building 1. An example of building 1 under construction, shown in FIG. 1, is shown diagrammatically with three exterior walls 2 assembled in a U, delimiting an interior volume separated in two by an interior wall 10 linked to the central exterior wall 2 by a joining edge 13. The exterior walls 2 can be either masonry brick walls, masonry walls made of solid or hollow concrete blocks and lightened, tiled walls, prefabricated walls with integrated formwork, insulated or not, and any type of wall that can be made. These exterior walls 2 and the interior wall 10 can be placed on any type of support, such as a prefabricated concrete base or poured on site, in masonry or the like, a lower floor, etc., and can be combined in the upper part. all types of slabs, made from solid slabs, beamed floors and interjoists, prefabricated slabs, insulated or not, or the like. In general, the term "prefabricated" means a construction element which can be manufactured industrially in the factory, then transported to the site, or produced on the site without being poured in place, then laid. These prefabricated building elements are generally made of a so-called hydraulic molding material, such as concrete or the like, stiffened by a metal frame, which may include projecting frames, with or without stiffening trusses, and commonly called precast concrete elements. armed.
    With reference to the figures, the manufacturing method according to the invention is described for an interior wall 10, 20, 30 prefabricated, commonly called premur or wall with integrated formwork, prefabricated in the factory and made of reinforced concrete. Well
    2017/5809
    BE2017 / 5809 understood, this example is not limitative and extends to the interior walls joined and poured on site or prefabricated in solid slabs (not shown).
    In particular, in the case of an interior wall laid and poured directly on site, the thermal insulation means and the connection reinforcements are positioned and fixed on at least one of the cheeks of the formwork before pouring the filling material. And in the case of an interior wall made from a prefabricated wall in solid slab, the thermal insulation means and the connection reinforcements are positioned and fixed in a suitable formwork mold before the pouring of a molding material for forming the solid slab of said prefabricated wall. In these different cases and depending on the specifications, thermal insulation means 40 will be chosen which extend over a height at most equal to the thickness of the interior wall produced to create a partial thermal break as explained below. .
    In the case of an interior wall 10, 20, 30 produced from a prefabricated wall with integrated formwork, this comprises in known manner two walls 11, 12, superimposed in two parallel planes and kept at a distance from each other on the other by spacers 14 to define an inner formwork 15 intended to be filled with a filling material cast on site, such as concrete. The two walls 11, 12, known by the name of "skins", are hereinafter called first wall 11 and second wall 12 without this definition being limiting. These two walls 11, 12 are preferably of parallelepipedal shape and identical dimensions, namely the same width or height, the same length and the same thickness, without however these characteristics being limiting. Indeed, for certain reasons, the shape of the walls could be different from a rectangular parallelepiped and their dimensions could also be different. These two walls 11, 12 are traditionally stiffened by a metal frame, shown in FIGS. 5, 5A by a stiffening mesh 16.
    2017/5809
    BE2017 / 5809
    Figures 2 and 3 illustrate in more detail the joining edge 13 of the interior wall 10 incorporating thermal insulation means 40 over its entire length and assembled to the exterior wall 2 of Figure 1. The thermal insulation means 40 are in the example illustrated, advantageously arranged in the extension of the thermal insulation means 3 provided on the inner face of the exterior walls 2 of the building 1 and thus at least partially ensure continuity of the thermal insulation through the interior of the building 1 (ITI). These thermal insulation means 40 are formed of a discontinuous row of several thermal breakers 41, this row being parallel to the junction edge 13, located in its closest environment to be disposed in the immediate vicinity of the exterior wall 2, or even of the inner face of this outer wall 2. In an embodiment not shown, one can imagine making these thermal insulation means 40 by a single thermal breaker which extends parallel along the junction edge 13 and which has a length lower than that of said junction edge 13 to provide two intervals I at the lower and upper ends of said interior wall to provide mechanical and structural connection with the exterior wall 2 as explained below.
    The object of the invention is to create a thermal break at the junction between the exterior wall and the interior wall, to greatly limit the formation of a thermal bridge, this thermal rupture being discontinuous as explained below. In the example shown, the thermal switches 41 are four in number, separated and spaced from one another by an interval I thus forming on either side of each thermal switch 41 a passage for reinforcements of connection 50. These connection reinforcements 50 are in the illustrated example formed of reinforcement cages 51, without this definition being limiting given that any type of metallic reinforcements making it possible to ensure a mechanical connection between two construction elements is possible. Thus, the various reinforcement cages 51 of the interior wall 10 are mutually parallel and distributed over the entire length of the joining edge 13, corresponding to the height of the interior wall 10. They are
    2017/5809
    BE2017 / 5809 protruding inside a junction zone 4 provided in the external wall 2 in order to be able to ensure the mechanical and structural connection of the internal wall 10 with the external wall 2 when this junction zone 4 is filled with a material filling, either separately or simultaneously with the filling of the interior formwork 15 of the interior wall 10. This junction zone 4 can correspond either to a separation between two adjacent exterior walls 2, or to a reservation formed by the assembly side by side of two adjacent exterior walls 2, or again at a reservation formed in a single exterior wall 2. Depending on the case, the junction area 4 is delimited by an exterior and / or interior formwork. Consequently, the intervals I delimited between the thermal breakers 41 are filled with filling material during filling of the interior formwork 15 of the interior wall 10, and form ribs of reinforced concrete which ensure a continuous mechanical and structural connection between the interior wall 10 and the exterior wall 2.
    FIGS. 4A, 4B and 4C illustrate three variants of integration of the thermal insulation means 40 in an interior wall 10, 20, 30 produced from a prefabricated wall with integrated formwork. FIG. 4A illustrates the interior wall 10 implemented in FIGS. 1 to 3 and in which the thermal switches 41 are integrated into the first wall 11 by passing right through it, and are flush with the interior face of the second wall 12 without penetrate it. In FIG. 4B, the thermal breakers 41 are integrated into the second wall 12 by passing right through it, and are flush with the internal face of the first wall 12 without penetrating it. And in FIG. 4C, the thermal switches 41 are integrated both in the first wall 11 and in the second wall 12 by passing through them both right through.
    The method of manufacturing the interior wall 10, illustrated in FIG. 4A is described more particularly with reference to FIGS. 5 to 9. It is a conventional method of manufacturing prefabricated walls with formwork integrated by molding in a
    2017/5809
    BE2017 / 5809 molding material, such as concrete or the like, of the two walls 11, 12 separately in two separate formwork molds 5, then by assembling the first wall 11 dried and turned over the second wall 12 in dipping the spacers 14 in the fresh concrete of the second wall 12 before drying. In the figures, the formwork molds 5 are shown diagrammatically by a plate, representing the bottom of the mold, the length and width of which correspond to the length and to the width or height of each wall 11, 12. In a first step of the process and with reference to FIG. 5, the spacers 14 and the stiffening trusses 16, as well as any other necessary reinforcing element, are positioned in the formwork mold 5 and in a manner known per se. To make the interior wall 10 according to the invention, there are added to this formwork mold 5 and along an edge which will form the junction edge 13 of said wall several thermal breakers 41 defined below, aligned to form a parallel row at the future junction edge 13, separated from each other by an interval I, and several reinforcing cages 51, extending perpendicular to the future junction edge 13 and each arranged in an interval I. The thermal switches 41 can be fixed directly on the bottom of the formwork mold 5 by gluing for example or any other suitable means to prevent them from moving during the casting of the molding material. The intervals I can be identical and compatible with the width of each reinforcement cage 51, also of identical dimensions. Of course, these examples are not limiting. The length of the thermal switches 41 may or may not be identical. It has been represented in FIG. 5A, two central thermal switches 41 of a first length and two thermal switches 41 of end of a second length less than the first length, in order to adjust the number of thermal switches 41 to the length of said junction edge 13 and to distribute the reinforcement cages 51 evenly over the width or height of said wall, according to the load constraints. When the formwork mold 5 is thus prepared according to FIGS. 5 and 5A, a molding material is poured over a determined thickness to form the first wall 11 of said wall according to FIGS. 6 and 6A, leaving the protrusions
    2017/5809
    BE2017 / 5809 spacers 14, the thermal switches 41 and the reinforcement cages 51. In this example, the thermal switches 41 have a total height less than the height of the spacers 14, and in particular equal to the thickness of the first wall 11 added to the thickness of the internal formwork 15. The first wall 11 is dried to harden the molding material in ambient air, in an oven or by any other known method. In a second step of the process, illustrated in FIG. 7, the stiffening trusses 16, as well as any other necessary reinforcing element, are positioned in another suitable formwork mold 5 and in a manner known per se. flows a molding material over a determined thickness to form the second wall 12 of said wall. In a third step, and before drying of the second wall 12, one returns above the second wall 12, the first wall 11 according to FIG. 8, then the spacers 14 and the reinforcement cages are immersed 51 in the fresh concrete of the second wall 12 according to FIG. 9, the thermal breakers 41 flush or slightly penetrating the second wall 12. The second wall 12 is dried to make the molding material harden. ambient air, in an oven or by any other known process, and mechanically link the two walls 11, 12. The prefabricated interior wall 10 obtained shown in top view in FIG. 9A only reveals the thermal switches 41 which are flush with the face exterior of the first wall 11. After demolding, the prefabricated interior wall 10 thus produced can be stored and then transported to the site to be assembled with exterior walls 2 in any type of building 1.
    The method of manufacturing the prefabricated interior wall 20, illustrated in FIG. 4B is similar to the method which has just been described and is only shown in FIGS. 10 and 10A, which correspond to the last step of said method. In this alternative embodiment, thermal breakers 41 are used having a total height less than the height of the spacers 14, and in particular equal to the thickness of the first wall 11 plus the thickness of the internal formwork 15, as in the previous example. In the first step of the process, the thermal breakers
    2017/5809
    BE2017 / 5809 are not fixed directly to the bottom of the formwork mold 5, but by means of a receiving support (not shown) to which they are linked, this receiving support being fixed in the formwork mold 5 or to the stiffening trusses 16, so that the thermal switches 41 are positioned above the first wall 11 without passing through it. Thus, during the step of assembling the first wall 11 to the second wall 12, the spacers 14, the reinforcement cages 51 and the thermal switches 41 are immersed in the fresh concrete of the second wall 12 according to Figure 10 so that the thermal breakers 41 enter the second wall 12 through it. One obtains an interior wall 20 prefabricated inverted with respect to the previous wall 10 in which the thermal breakers 41 are flush with the exterior face of the second wall 12. The solution of integrating on the one hand the spacers 14 in the first wall 11 and on the other hand the thermal breakers 41 and the reinforcement cages 51 in the second wall 12 cannot be envisaged. Indeed, the assembly of the two walls 11, 12 requires the penetration of the spacers 14, the thermal breakers 41 and the reinforcement cages 51 in the fresh concrete of the second wall 12 molded last. In fact, all the elements which must be linked or be linked to the two walls 11, 12 must be provided on a single wall 11.
    The method of manufacturing the prefabricated interior wall 30, illustrated in FIG. 4C is also similar to the method described for the wall 10 and is only shown in FIGS. 11 and 11A, which correspond to the last step of said method. In this alternative embodiment, thermal breakers 41 are used having a total height greater than the height of the spacers 14, and in particular equal to the thickness of the two walls 11, 12 plus the thickness of the internal formwork 15. In the first step of the process, the thermal breakers 41 are fixed directly to the bottom of the formwork mold 5 to pass through the thickness of the first wall 11. Thus, during the step of assembling the first wall 11 to the second wall 12, the spacers 14, the reinforcement cages 51 and the thermal switches 41 are immersed in the fresh concrete of the second wall 12 according to FIG. 11 so that the
    2017/5809
    BE2017 / 5809 thermal breakers 41 penetrate into the second wall 12 through it. A prefabricated interior wall 30 is obtained in which the thermal breakers 41 are flush with the exterior face of the first wall 11 and of the second wall 12.
    Of course, any other embodiment is possible, in particular that in which the thermal switches 41 do not pass through the first wall 11 or the second wall 12, and thus do not lie flush with any of the exterior faces of said interior wall 10, 20, 30. In in this case, the thermal performance will not be optimal.
    In the various examples illustrated, the thermal breakers 41 consist of insulation bars which have the general shape of a rectangular parallelepiped, without this shape being limiting. In addition, they can all have the same length, or have different lengths as explained above, in particular with reference to FIG. 5A making it possible to adapt the length of the row of thermal switches 41 to the length of the junction edge 13. Their width can be determined as a function of the efficiency of the thermal break sought, but also as a function of the interior insulation layer 3 provided on the interior face of the exterior walls 2. According to their implementation during the manufacture of the interior wall 10, 20, 30, they may or may not be linked to a reception support (not shown). The supports for receiving the thermal switches 41, only present in the variant embodiment of FIG. 4B, can be in the form of an open container making it possible to receive the thermal switch 41. Other shapes may be suitable such as a simple plate, U-shaped stirrups, a mesh basket, etc. They may include anchoring members to be embedded in the first wall 11 of said wall for example with reference to the variant illustrated in Figures 4B, 10 and 10A. They can be made of synthetic materials, composite materials, wood, metal, cardboard or any compatible material. These reception supports
    2017/5809
    BE2017 / 5809 may or may not correspond to those described in the applicant's publication FR 2 861 767 B1.
    In addition, these thermal breakers 41 each include at least one insulating bar, made of one or more at least thermally insulating materials, such as expanded polystyrene, expanded polyurethane, expanded perlite, cellular concrete, glass wool. , rock wool, cellulose or any other at least thermally insulating material, presented in particles, balls, fibers, bread or more or less compact block. These thermally insulating materials may also have additional properties, in particular fire-resistant properties, or may be combined with other materials providing these additional properties, such as expanded perlite, ceramic, silica-limestone or any other material which fire, presented in particles, balls, fibers, bread or more or less compact block, plate, etc. The insulation rolls can also be packaged in protective packaging or the like to protect them from moisture. In the prefabricated interior walls 10 and 20, according to FIGS. 4A, 4B and 5 to 10, the thermal breakers 41 may have only a thermal insulation function since one of the walls 11, 12 of said wall does not is not crossed by the thermal switches 41 and thus ensures a tight barrier to flames and gases in the event of fire, as well as to noise. While the interior wall 30 prefabricated according to Figures 4C and 10 must have thermal switches 41 having an additional fire function.
    Industrial application possibilities:
    As explained above, the interior walls 10, 20, 30 according to the invention are manufactured according to a traditional molding process and can then be implemented on site in the traditional way like any other type of wall, prefabricated wall with solid slab or classic integrated formwork wall. The
    2017/5809
    BE2017 / 5809 exterior walls 2 can be made before or after the implementation of said interior walls 10, 20, 30, depending on the construction technique used.
