Definitions

  • the present invention relates to a modular building system, which can be used mainly for constructing a single or double wall, in particular a load-bearing exterior wall or a non-load-bearing exterior wall of the mantle wall type.
  • the present invention also relates to a building module, which can be used mainly for constructing a single or double wall, in particular a load-bearing exterior wall or a non-load-bearing exterior wall of the mantle wall type.
  • the invention mainly finds its applications in the field of construction.
  • each box comprises two front panels on which are permanently fixed external uprights which are made of wood, in particular solid wood, and on which an aesthetic and/or functional structure can be added, such as cladding and/or interior facing.
  • each box comprises two metal front walls, each with two returns, which make it possible to form a U-shape on the outside of the box and onto which an aesthetic and/or functional structure can be added, such as cladding and/or interior facing.
  • boxes disclosed in this American patent US 4,193,244 can also be used to construct a horizontal structure such as a roof.
  • the external supports are permanently fixed (wooden uprights) or are an integral part (U-shaped returns) of the box, which makes this solution not very flexible for fixing an aesthetic and/or functional structure such as cladding or interior facing to the box, which constitutes a second disadvantage.
  • the European patent application EP 3553244 A1 also discloses a hollow construction module that can be used primarily for constructing a wall, in particular a load-bearing wall or a sheath wall.
  • This module consists of a box, which is rectangular parallelepiped in shape, and which comprises two side panels, forming the sides of the module and two front panels connecting the two side panels.
  • the box is made in a single piece, from a composite material based on plastic material(s) and reinforcing material(s), for example by molding, extrusion or pultrusion.
  • the box may contain thermal and/or acoustic insulation.
  • This box has L-shaped profiles protruding from the outside on one of its front panels and flat profiles protruding from the outside on its other front panel. These profiles are an integral part of the box and allow an aesthetic and/or functional structure to be added to the box, such as cladding or interior facing or even photovoltaic panels.
  • This box also has two grooves which are made in the external wall of each side panel, and which are vertical and spaced in the lateral direction perpendicular to the front panels. These grooves are intended to house a part of a sealing gasket ensuring a seal between two adjoining boxes.
  • the sealing joints between two adjoining boxes allow two adjacent boxes to fit together and, in cooperation with the grooves, contribute to a certain extent to the alignment of the boxes.
  • the profiles which allow an aesthetic and/or functional structure to be added to the box prevent the installation of a rain-proof film and/or a vapour barrier film on the box, and in practice make the box unsuitable for achieving effective sealing by means of a rain-proof film and/or a vapour barrier film, which constitutes a third disadvantage.
  • a first main and general objective of the invention is to propose a modular construction system, which comprises construction modules intended to be assembled end to end, which makes it possible to support at least one added aesthetic and/or functional structure, and which overcomes at least the first drawback (alignment of the construction modules) and the second drawback (flexibility) mentioned above, and where appropriate also the third drawback mentioned above when it is necessary to achieve sealing by means of a rain barrier and/or a vapor barrier.
  • this modular construction system can be used to build a wall, and in particular a load-bearing wall.
  • a second main and general objective of the invention is to propose construction modules which are intended to be assembled end to end and which overcome at least the first drawback (alignment of the construction modules) and the second drawback (flexibility) mentioned above, and where appropriate also the third drawback mentioned above when it is necessary to achieve sealing by means of a rain barrier and/or a vapour barrier.

  • the fixing(s) can be through or non-through.
  • the fasteners are through-bolts, they are suitable for assembling and tightening the two boxes by being passed through the two external side walls of the two boxes facing each other.
  • the through-bolt fastener(s) may be of the through-screw or bolt type.
  • the invention also has as a second object a use of the aforementioned modular construction system for constructing a wall, preferably a load-bearing wall.

  • the panel 15' may also be a mesh.
  • the open face 16a of the internal space of each box 1-1 and 1-2 can also remain open, without using a panel 15'.
  • Steps (b) to (g) can be repeated as many times as necessary with additional building modules until a wall of the desired length is obtained.
  • a vapor barrier 18 for example in the form of a tarpaulin impermeable to water and water vapor, can also be carried out on the external walls 15a of the panels 15'.
  • vapor barrier is generally and commonly used to refer to a protective screen that is impermeable to water and water vapor. Thus, the humidity present in the air in the form of condensation does not cannot pass through this protective screen.
  • a cladding 4 is fixed on the soles S2, with support function, of the junction profiles 2A, and an interior facing 5 is fixed on the soles S2, with support function, of the junction profiles 3A.
  • the load borne by the load-bearing wall (weight of the frame and the floor system) is taken up by the boxes of the construction modules and is not carried out by the junction profiles.
  • the inner panel 15' may be temporarily and removably assembled to the frame of the box to the box 1 from the stage of manufacturing the box in the workshop or factory.
  • this inner panel 15' is first removed from the box to carry out the fixing to the ground and the fixing of the box with another box and to carry out the filling of the box with the insulation I. Then once the box is assembled and fixed to the ground and the insulation I has been placed in the box, the panel 15' is permanently fixed to the frame of box 1.
  • This double wall is built, for example, when seeking to increase thermal and/or acoustic insulation priorities.
  • This double wall is constructed using four construction modules M1, M2, M3 and M4, the same two junction profiles 2A and 3A and a third junction profile 3I, allowing the two single walls MS1 and MS2 to be spaced apart.
  • the simple wall MS1 made using the construction modules M1 and M2, is identical to the simple wall of the figure 8 , with the only difference that the 3A junction profile of the figure 8 has been replaced by a junction profile 31.
  • Modules M3 and M4 differ essentially from modules M1 and M2 in that they do not include a rain barrier 17 (or a vapor barrier 18).
  • the third profile 3I differs from the profiles 2A and 3A previously described in that the width of its core 20, which defines the spacing distance between the two simple walls MS1 and MS2, is greater and in that the widths of the two flanges S1 (wings 21, 22) and S2 (wings 23 and 24) of the junction profile 3I are identical.
  • This double wall was constructed by inserting the first wing 21 and the second wing 22 of the third profile 4 into the grooves R2 facing each other of the modules M1 and M2, and by inserting the third wing 23 and the fourth wing 24 of the third profile 4 into the grooves R1 facing each other of the modules M3 and M4.
  • the panel 15 of the interior modules M3 and M4 is micro-perforated so as to allow condensation to migrate.
  • This M construction module differs from that of the Figure 6 , in that the flaps 17a of the rain shield 17' are fixed, temporarily or permanently, for example by being stapled, to the two external side walls 10a and 11a of the box between the two grooves R1 and R2 of the upright 10 and between the two grooves R1 and R2 of the upright 11.
  • the rain shield 17' is locally pressed into the grooves R1 of the uprights 10 and 11.
  • the insertion of the wing 21 and the wing 22 of the profile 2A into the grooves R1 advantageously makes it possible to wedge the rain shield 17' into the groove R1 of the box of the module M1 and into the groove R1 of the box of the module M2.
  • the rain shield 17' can also cover the groove R1 of the upright 10 and cover the groove R1 of the upright 11.
  • the insertion of the wing 21 and the wing 22 of the profile 2A into the grooves R1 advantageously makes it possible to push and wedge the rain shield 17' into the groove R1 of the box of the module M1 and into the groove R1 of the box of the module M2.
  • the building module also includes a flexible 18' vapor barrier, which is attached to box 1.
  • This 18' vapor barrier is, for example, a film or tarpaulin impermeable to water and water vapor which is fixed around the entire perimeter of the box.
  • the 18' vapor barrier is locally pressed into the R2 grooves of the uprights 10 and 11.
  • the insertion of the wing 21 and the wing 22 of the profile 3A into the grooves R2 advantageously makes it possible to wedge the vapor barrier 18' into the groove R2 of the box of the module M1 and into the groove R2 of the box of the module M2.
  • the vapor barrier 18' further comprises two strips 18a and 18b which are folded down so as to close the open face 1" of the box opposite the panel 15, and which overlap at the level of the internal reinforcement 14. These two strips 18a and 18b are held together by means of a repositionable adhesive strip 18c, allowing a seal between the two parts of the two strips 18a and 18b which overlap.
  • the two strips 18a and 18b can be opened by peeling off the adhesive strip 18c, so as to be able to access the internal space 16 of the box 1 and to be able to put in place the insulation I in the box 1 and, if necessary, to put in place the internal panel 15'.
  • the strips 18a and 18b of this vapor barrier 18' can be folded down onto the panel 15' and fixed by bonding using 18c adhesive tape to the external wall of the 15' interior panel, so as to ensure water and water vapor tightness.
  • the strips 18a and 18b of this vapor barrier 18' can be folded down and glued to the reinforcement 14 by means of the adhesive strip 18c, so as to close the internal space 16 of the box and to ensure watertightness and water vapor tightness.
  • junction profiles 2 and 3 are also possible.
  • junction profiles 2 (3) which have in common the fact that they are profiles reconstituted by welding.
  • the 2D (3D) junction profile comprises two U-shaped sub-profiles 25, which extend along the junction profile, which are symmetrical to each other with respect to the thin web 20 of the profile, the bases 25c of which are welded on either side of the web 20 of the profile, and the two wings 25a and 25b of which are oriented perpendicular to the web 20 of the profile.
  • the core 20 of the junction profile comprises through holes 20b, of small diameter, distributed along the junction profile and allowing a plug weld on the core 20 of the bases 25c of the U-shaped sub-profiles 25.
  • U-shaped sub-profiles 25 can advantageously be used to embed the edge of a P1 panel on the construction module, and for example (2D profile) an additional insulating panel, mounted on the side of the construction module facing outwards and parallel to the exterior panel 15 or (3D profile) an additional insulating panel, mounted on the side of the construction module facing inwards and parallel to the interior panel 15'.
  • the 2E (3E) junction profile of the figure 20 differs from the profile 2D (3D) of the figure 19 , by the presence of two additional wings 26, which are positioned between the U-shaped sub-profiles and the wings 21 and 22 and which are symmetrical to each other on either side of the web 20 of the profile.
  • These wings 26 and the wings 25b of the U-shaped sub-profiles 25 can advantageously be used to embed the edge of a panel P2 on the construction module.
  • the 2F (3F) junction profile of the figure 21 differs from the 2E (3E) profile of the figure 19 by the presence of two additional 25' U-shaped sub-profiles between the S2 sole and the 25' U-shaped sub-profile. These 25' U-shaped sub-profiles can advantageously be used to embed the edge of an additional P3 panel.
  • the modular construction system can be implemented with a very wide variety of junction profiles, which makes it very flexible and easily adaptable for the construction of walls with varied and more or less complex structures, in particular with a greater or lesser number of insulating panels.
  • the M5 and M6 building modules are suitable for being assembled perpendicular to each other, so as to form an outgoing wall angle.
  • the side wall 10a of the box of the construction module M5 is vertical and perpendicular to the frontal direction (X direction) of the box and the other side wall 11a of the box is vertical and forms an angle A of 45° with the internal wall 15b of the external panel 15.
