Description

Device for assembling prefabricated modules and corresponding prefabricated module structure. FIELD OF THE INVENTION The field of the invention is in particular that of building and construction, but also that of construction games. More specifically, the invention relates to a prefabricated module assembly technique for the modular construction of habitable buildings or not. The invention further relates to a structure of prefabricated modules. 2. Solutions of the Prior Art Modular building systems of buildings are numerous and varied. They use, in a conventional manner, prefabricated building elements that are assembled by interlocking or by a specific assembly (or attachment) device. An example of a specific assembly device is described in US Pat. No. 6,014,842. It allows an assembly of prefabricated elements which each comprise a frame consisting of two vertical uprights connected by high and low rails.

These prefabricated elements are assembled in vertical and horizontal planes so as to define primary and secondary frames forming a load-bearing structure on which cladding panels are fixed to form a floor or a roof, for example. In one embodiment, two prefabricated elements are assembled edge to edge, that is to say that an amount of a first prefabricated element is brought into contact in the same plane with an amount of a second prefabricated element, by means of an assembly device which implements: two rectangular-shaped connecting plates which are placed symmetrically on the opposite external faces of the prefabricated elements, at the junction of the adjoining amounts of the prefabricated elements so as to overlap these amounts. These connecting plates are pierced with four holes and interconnected by means of bolts which pass through the thickness of the amounts from one side to the other and which are immobilized with nuts. These plates provide an assembly of the two prefabricated elements in tension, that is to say that they limit the spacing between the two prefabricated elements. - Two upper and lower threaded rods passing right through the adjoining amounts of each prefabricated element and which are fixed with nuts. These rods and nuts, mounted inside the frame of the prefabricated elements, provide an assembly of these two elements in compression, that is to say that they can compress the two prefabricated elements.

A disadvantage of such an assembly technique is that the compression assembly is implemented inside the frame of the prefabricated elements. Access to the rods and nuts ensuring this compression assembly is complex, especially once the prefabricated elements are covered with cladding panels.

In addition, in the conventional case where it would be desirable to insert a waterproofing membrane between the adjoining amounts of each prefabricated element, it would be necessary to drill this membrane to allow the passage of the two upper and lower threaded rods passing right through the adjoining amounts. Another disadvantage of this assembly technique is that it requires multiple assembly elements (plates, screws). Moreover, the assembly of the construction described in this patent requires multiple interventions. Thus, after assembling the prefabricated elements defining a supporting structure, it is necessary to then lay the insulation and the outer and inner cladding. Subsequent adaptations of the construction (that is to say the modularity of the construction) are also not easy to implement. In addition, the structure of the prefabricated elements to be assembled on the site being open, the construction is not sheltered from the weather as long as the outer covering has not been laid.

In other words, this solution is not entirely satisfactory, particularly because it is costly in time and product, it poses problems of sealing and accessibility, and it also requires the implementation implementation of delicate operations to achieve. 3. OBJECTIVES OF THE INVENTION The object of the invention is notably to overcome these disadvantages of the prior art. More specifically, an objective of at least one embodiment of the invention is to provide a device for assembling prefabricated building modules making it possible to limit the number of assembly parts used, and thus to reduce costs. .

Another objective of at least one embodiment of the invention is to implement a device for assembling prefabricated building modules which is easy and quick to set up, which is reliable and which, overall, reduces the number of operations to be performed during the construction of a building.

Yet another object of at least one embodiment of the invention is to provide a prefabricated element that is robust, waterproof and has good thermal performance (reduction of air infiltration and thermal bridges, in particular). 4. ESSENTIAL CHARACTERISTICS OF THE INVENTION These objectives, as well as others which will appear subsequently, are achieved by means of an assembly device of at least three prefabricated building modules. such assembly device comprises at least one integral connecting plate comprising: a first portion intended to be placed on an outer face of said first module, and having at least a first slot capable of being traversed by first fixing means of said means; linking to said first module; and a second portion intended to be placed on an outer face of said second module, and having at least one second light capable of being traversed by second means for fixing said connecting means on said second module; a third portion intended to be placed on an outer face of said third module, and having at least a third light adapted to be traversed by third fastening means of said connecting means on said third module. Thus, the invention is based on a completely new and inventive approach according to which the means used for the compression assembly of three or more prefabricated modules are the same as those used for the assembly in tension. of these three modules.

In addition, these same means ensuring both the assembly in tension and in compression are mounted exclusively outside the prefabricated modules. To do this, the prefabricated modules are connected by connecting means which are mounted partly on an outer face of one of the prefabricated modules and partly on an outer face of each of the other prefabricated modules. These connecting means are provided with lights in which there is engaged fixing means. The fixing means completely or partially pass through the prefabricated modules, in pre-drilled holes or not, and make it possible to fix the connection means on the prefabricated modules and to assemble the latter.

Because the lights of the connecting means are non-parallel, the attachment of the connecting means on the modules not only compresses the prefabricated modules but also to limit the spacing between these modules. The assembly device of the invention is used, for example, to assemble several prefabricated modules so as to form beams, floors or roofs in particular. In this type of structure, each prefabricated module is subjected to compression on its upper part due to the assembly in compression and a stretch on its lower part which is limited by the assembly in tension.

It is thus clear that the compression and traction assembly device of the invention makes it possible to stiffen such a structure formed from several prefabricated modules. Advantageously, at least one of said portions has at least two lumens, each of said at least two lumens being able to be traversed by fixing means of said connecting means on said corresponding module.

Advantageously, the respective centers of said lumens are located on a circle whose center is the center of said connecting plate. In an alternative, the respective centers of the lights are located on at least two concentric circles whose center is the center of said connecting plate.

Preferably, each of said slots is of oblong shape. The connecting means have at least one oblong, straight or non-rectilinear slot in order to be able to adapt these connecting pieces to approximate holes. It may therefore be necessary to manipulate a connecting piece so as to match the fixing holes with each of the lights in such a room. The fastening means are inexpensive and easy to implement. The fixing system of the invention is not necessarily through. It can be mixed (crossing and non-crossing) in some cases.

Advantageously, the longitudinal axis of each of said slots is inclined at an angle greater than or equal to 5 ° with respect to the tangent to the circle passing through the center of said light. In a particular embodiment, said connecting plate comprises at least one notch or element protruding on its contour.

Advantageously, said connecting plate bears on one of its faces at least one reinforcing element. In a particular embodiment, the assembly device implements at least two identical connecting plates and superimposed symmetrically on the same outer face of at least one prefabricated building module. The invention also relates to a prefabricated building module intended to be secured to at least one other prefabricated building module by means of an assembly device as described above. In a preferred embodiment, said module comprises a peripheral frame, at least one face of said module being closed by a closure panel, said module comprising a vapor barrier membrane extending at least on the inner face of said closure panel and on the outer edge of said peripheral frame. Advantageously, the outer edge of the peripheral frame of said module comprises a groove for receiving at least one self-inflating seal.

The prefabricated building module of the invention comprises an outer frame formed, for example, of vertical uprights and crossbars high and low, and an inner frame formed of at least one upright and / or crosses. The outer frame and the elements of the inner frame of such a module constitute areas of contact and attachment with one or more other prefabricated building modules. Such an approach multiplies the possibilities of assembly between prefabricated modules. The elements of the frame and the internal frame of a prefabricated module can be pre-drilled at the factory during the construction of the module or on site, the holes thus drilled allowing the establishment of the means for fixing the connecting means. . Drilling on site is particularly advantageous in that it allows the establishment of connection means according to the wishes of the installer. The prefabricated module of the invention can be made to measure or in advance, without a predefined destination, in a relatively short time. It is also economical to manufacture. Such building modules can be prefabricated in the workshop, sheltered from the weather, before transport to the site where a simple assembly operation of the prefabricated modules is necessary.

The principle of construction of the invention is particularly, but not exclusively, adapted to the residential construction market (individual and collective housing) or commercial. It can also be implemented in the renovation, but also for temporary, progressive or permanent constructions such as bleachers, podiums, footbridges, scaffolding, formwork, sheds, stands, fences, models, ramps, stairs, partitions, floors techniques, etc. In addition, the structure once assembled is easily adjustable if you want to enlarge and / or modify the construction. The prefabricated modules of the invention are further adapted to the construction of green buildings, the prefabricated modules meeting the standards required for buildings entering the low consumption category and being designed to be recycled during the deconstruction of the building. Furthermore, the construction principle of the invention allows to install a building out of water and out of air quickly. The invention furthermore relates to a method of assembling a first prefabricated module and a second prefabricated module, comprising the steps of: bringing said first module into contact with said second module; drilling a first hole in said first module; setting up a first portion of connection means on an outer face of said first module and a second portion of said connecting means on an outer face of said second module, said first portion comprising a first light and said second portion comprising a second light; setting up first means for fixing said connecting means on the first module, said first fixing means cooperating with said first light; drilling a second hole in said second module; - Rotating adjustment of the position of said connecting means around the first fastening means so that said second hole opens into said second light; Placing second means for attaching said connecting means to the second module, said second fixing means cooperating with said second light; - Tightening of the first and second fixing means thus ensuring an assembly of said modules in compression and traction. Such an assembly method allows, once the connecting means attached to a first prefabricated building module by means of first fixing means, to drill a hole in the second prefabricated building module and to move the connection means around first fixing means so as to match the hole thus pierced with a light of the connecting means.

Once this adjustment is made, the second attachment means of the connecting means can be put in place in this light and this hole. The drilling of the fixing holes in two modules to be assembled can be performed approximately, the shape of the lights in the connecting means for matching each of the holes with a light of the connecting means, adjusting the position of the means of link if necessary. In a particular embodiment, the assembly method further comprises, after the step of setting up second fastening means and prior to the clamping step, a step of adjusting the connecting means in such a way that reducing or increasing the space between said first module and said second module. 5.

DESCRIPTION OF AN EMBODIMENT OF THE INVENTION 6.1 GENERAL PRINCIPLE The invention relates to a technique for assembling prefabricated building modules, in particular for the modular construction of buildings. This technique makes it possible to connect several prefabricated modules, for example two prefabricated modules arranged in the same plane or in different planes, and to assemble in traction and compression these two modules by means of a single device. assembly, which is accessible from outside the modules. In addition, the prefabricated modules comprise an external frame and an internal frame which, once drilled, allow to assemble these modules in three dimensions so as to constitute for example walls, floors, beams and roofs. These modules, in a particular embodiment, implement a sealing membrane on at least a portion of their outer and inner walls. 6.2 Examples of prefabricated building modules FIGS. 1A, 2 and 3 are front views of three types of prefabricated building module according to the invention. The prefabricated module 100 consists of an external framework in the form of a peripheral frame formed by two vertical outer uprights 101, 102, connected by a high outer cross member 103 and a low outer cross member 104. The module 100 thus formed delimits a interior space in which is mounted an internal frame. This inner frame comprises, in the example illustrated in FIG. 1A, two vertical inner uprights 111, 112, intersecting with two horizontal inner crosspieces 113, 114, and two diagonal inner crosspieces 115, 116. These two diagonal crosspieces 115, 116 are integrated or not in the module during its prefabrication, their position and inclination can be chosen according to the needs. They allow the assembly of the module 100 with at least one other prefabricated module when the latter comes into contact with the area delimited by these two crosspieces 115, 116. FIG. 1B is a sectional view of the module of FIG. external amounts 101, 102 and the inner amounts 111, 112 which present in this example a rectangular profile of length e and width b. The profile of the amounts and cross members of the module 100 is identical.

The outer and inner frames of the module 100 can be made of wood or metal, for example, or a combination of several materials.

In the example illustrated in FIG. 2, the outer frame of the module 200 comprises the vertical outer uprights 201, 202, connected by high 203 and low 204 external sleepers. The inner frame comprises three vertical inner uprights 205, 206, 207, and two horizontal inner cross members 208, 209. The cross member 206 may or may not be integrated with the module 200 during its prefabrication, its position being different from that illustrated. Its integration offers additional assembly possibilities with at least one other prefabricated module.

The shape of the modules may be different from a rectangular shape. Thus, FIG. 3 shows a curved or semi-circular prefabricated module 300, which comprises: an external framework consisting of the crossmember 304 and the semi-circular crossmember 303, and an internal framework consisting of two vertical uprights 310, 311 , a horizontal cross member 313 and a semicircular cross member 312. Other non-exhaustive examples of prefabricated modules are illustrated in FIG. 4A. The module 400 comprises two vertical external uprights 401, 402, connected by an external cross member. 403 high and a low 404 exterior cross member. It further comprises four vertical vertical uprights 410 to 413 and two horizontal inner cross members 414, 415. The structure of the modules 500 to 900 shown in FIG. 4A is substantially identical to the module 400 (the references numerals have therefore been incremented by 100). The structure of the module 900 is substantially identical to the module 100 of FIG. 1. The internal framework of the modules illustrated in FIGS. 1 to 4A defines housings 120 to 920 into which one or more filler materials may be inserted, such as a thermal and / or phonic insulation, of hemp and linen type, for example. Alternatively, or in addition, a filling with a concrete type mass material for example can be inserted, so as to ballast the module and therefore the building in the case where one is on a low floor for example. These housings 120 to 920 possibly allow the passage of electrical cables or plumbing pipes, for example, before the establishment of the insulation. Cable trays can alternatively be fixed on the outside of the modules, which facilitates their access and subsequent evolutions. In a variant illustrated in Figure 4B, lights 222 ', 422' are provided in some or all of the crossbars and internal uprights of the modules 200 'and 400'. These lights 222 ', 422' can receive one or more filler materials. One or both sides of a prefabricated module can be closed, partially or totally, by means of a closure and bracing panel, such a panel being removable or fixed. Such a panel consists of a single piece or several parts assembled together. Such a closing and bracing panel may be wood for example or plaster allowing the construction of plaster walls when several prefabricated modules are assembled vertically. In other words, a prefabricated module can be open, partially closed or closed. When a module is closed on both sides, it is understood that the inner frame, and possibly the filling material, are inaccessible if not to remove the closure panels fixed on the faces of the module. In FIG. 4B, there is illustrated a closure and bracing panel 250 '(in plaster in this case) which is intended to partially close one face of the module 200'. Preferably, a seal 90 is interposed at the junction of the modules to seal these junction areas and provide optimum insulation. In a variant, the installation of a joint (in the workshop or on the construction site) on the periphery of the prefabricated module makes it possible: to guarantee a perfect seal, especially in air, and to make the module conform to the required standards for BBC buildings (for "low energy buildings"). Furthermore, the inner and outer uprights and cross members of the prefabricated modules of the invention, and in particular modules 100 to 900, 200 'and 400' define drilling and fixing zones. Thus, fixing holes 121, 221 (visible only in FIGS. 1A and 2), through or not, may be provided at all locations on these uprights and crosspieces, and on each face of the module, so as to fix therein connecting parts (which will be described in more detail later) and to assemble the modules together in three dimensions of space.

These holes 121, 221 can be pierced from one side to accommodate a threaded rod for example, or be partially drilled to accommodate a socket for example. They can be drilled on site before the modules are fixed together, thus allowing a great modularity in the arrangement of the prefabricated modules. It should be noted that these fixing holes 121, 221 can be drilled during manufacture in the workshop prefabricated modules. The position of the holes is not limited to that shown in Figures 1A and 2, and other positions can of course be chosen. In addition, the shape and thickness of the prefabricated modules, as well as the number, profile and arrangement of the uprights and internal cross members of these modules may vary depending on the needs. These modules can thus be modulated on demand. In addition, the inclination of the inner diagonal crosspieces (referenced 115, 116 in Figure 1A for example) may vary. Moreover, the construction of a habitable or non-habitable building may be based on the implementation of several types of prefabricated modules, but it will obviously be possible to build a building from a single type of prefabricated module (this module can thus be manufactured in large series). 6.3 Examples of assembly devices for prefabricated modules FIG. 5A shows a first example of a connecting piece 30 that can be implemented in the device for assembling prefabricated modules according to the invention. This connecting piece 30 is intended, for example, to connect two adjacent prefabricated modules, that is to say two modules in the same plane singing against edge (see Figure 10D), or two modules arranged perpendicularly (we speak then assembly of modules at an angle, see Figure 10B). It allows, for example, the assembly of two modules 100, or of the module 100 with the module 200.

This part 30, called plate or connecting plate, is square in this example and is preferably made of metal. Such a connecting piece may take other forms, including a diamond shape, triangle or round, depending on the desired aesthetic. In this embodiment of the invention, the connecting piece 30 comprises two oblong slots 31 and 32 respectively located on a first and a second portion 30A, 30B of the piece 30. These two lights 31, 32 have a length equal to b and a width equal to 1 / 5b. The first lumen 31 is substantially parallel to the vertical axis of symmetry A of the connecting piece 30 and the second lumen 32 is, in this example, inclined by 10 ° with respect to the first lumen 31. The center of each lumen 31 , 32 is located at equal distance (in this case 1 / 2b, ie half the width of the crosspieces and uprights of the module 100) of the vertical axis of symmetry A of the connecting piece 30. Because the two lights 31, 32 are not parallel, their spacing, when measured in a plane perpendicular to the axis A, varies. Thus, the center distance E (whose value is less than b) is less than the center distance E '(whose value is greater than b). The two lights are not parallel to each other so as to ensure an assembly of two modules in compression and traction. FIG. 5B shows two juxtaposed and unassembled modules M1 and M2, a connecting piece 30 of the type shown in FIG. 5A being placed on the edge of these modules M1, M2, in this case on the upper cross member 103, 103 'of the modules M1, M2 respectively. Fastening means F cooperate with the light 31 of the connecting piece 30 and ensure the attachment of the connecting piece 30 to the module M1. These fastening means F are housed in a hole previously drilled in the high cross member 103 of the module M1. Such a hole is drilled on the site, for example, by a poser. In order to fix the connecting piece 30 on the module M2 and to assemble the modules M1 and M2, it is possible to drill the upper cross member 103 'of the module M2 into the piercing zone P represented in solid lines. This piercing zone P is obtained by pivoting the connecting piece 30 around the attachment F. It is understood that depending on the shape of the light 32, the shape of this piercing zone P varies. In any case, this piercing zone P offers the installer multiple possibilities of drilling on the site and great flexibility in laying the connecting piece 30.

Although this is not illustrated in this figure, it is understood that once the drilling in the high cross member 103 'M2 module performed, the installer adjusts the connecting piece 30 so as to match the hole thus pierced and the light 32. This adjustment operation performed, the installer can introduce a fixing in the slot 32 and in the hole in the high cross member 103 ', which allows to fix the connecting piece 30 on the module M2 and assemble the M1 and M2 modules in compression and traction. The connecting piece 30 can be partially fixed on the module M2 at first, and the hammered plate to reduce the gap between the fasteners, and therefore the modules, and thus improve the compression. The non-circular shape of the light 32 offers therefore to the installer multiple possibilities of fixing the connecting piece on the module M2. It also allows, once the fasteners are partially tightened, to reduce the clearance between two modules (that is to say, bring the two modules together) or to increase this game (that is to say, to separate the two modules).

The connecting piece can be used as a template for the installer to locate where the mounting holes are to be made. Once the connecting piece is removed, the installer drills the holes and installs the connecting piece to fix it on the modules. The drilling approximations may be previously compensated, because the connecting piece comprises at least one non-circular light, playing on the orientation of the plate. FIGS. 6A to 6C show different views of a second type of connecting piece 40 of the assembly device of two prefabricated modules according to the invention. This connecting piece 40 is intended to connect two prefabricated modules located in different planes. It is in the form of a bracket or angle having an edge A 'and whose portions 40A, 40B are separated by an angle substantially equal to 90 °. The portion 40A comprises a lumen 41 substantially parallel to the edge A 'and the portion 40B comprises a lumen 42 inclined in this example at an angle of 10 ° relative to the edge A' and relative to the first lumen 41 In the same way, the spacing E between the slots 41 and 42 varies when measured along the axis of the edge A '. The two lights 41, 42 have a length equal to b and a width equal to 1 / 5b. The center of each lumen 41, 42 is located at equal distance (in this case 1 / 2b is half the width of the crosspieces and uprights of the module 100) of the edge A '. It will be noted that the angle between the first and second portions 40A, 40B may vary, the limits being those which do not make it technically possible to place the fixing means (rods, bushes, dowels) or else to bolt and / or tighten the fastening means (nuts and bolts).

The shape, dimensions and inclination of the lights may be different from those shown in FIGS. 5A to 6C. Figure 7 illustrates other forms and (non-exhaustive) arrangements of lights in platinum-shaped connecting pieces. Of course, the same shapes and arrangements can be provided in connecting pieces whose portions 40A and 40B extend in non-parallel planes (in particular the square-shaped connecting pieces). The connecting piece 50 thus comprises an oblong straight slot 51 and a non-rectilinear slot 52. The connecting piece 60 comprises two lights 61, 62 curved and symmetrical. The connecting piece 70 comprises two lights 71, 72 curved and symmetrical. The connecting piece 80 comprises a rectilinear slot 81 and a non-rectilinear slot 82 which extend from the lower edge of the piece 80. The connecting piece 90 comprises a curved slot 91 and a circular hole 92. It will be noted that, according to the case, the lights of the same connecting piece are symmetrical or asymmetrical but that, in all cases, the distance between these lights varies. Thus, as illustrated in FIG. 7, the center distance E is different from the center distance E '.

A connecting piece, such as the connecting plate 30 or the connecting square 40, can be fixed on two modules to be assembled by means of fixing means which cooperate with the two lights of the connecting piece (whatever the shape and arrangement of the lights) and comprise, for example: a) a pair of bolts each intended to cooperate with a socket which is arranged in a non-through mounting hole provided on each module to be assembled, or b) a pair of bolts intended to to cooperate each with a bushing formed on each module to be assembled, or c) a pair of threaded rods intended to cooperate each with two nuts, each threaded rod being inserted into a through-fixing hole provided on each module to be assembled, or ) a combination of the above fastening means, such as a bolt for cooperating with a bushing which is arranged in a non-through mounting hole a module to be assembled and a threaded rod intended to cooperate with two nuts, the threaded rod being inserted into a through-fixing hole formed in the other module to be assembled. 6.4 Examples of assembly of prefabricated modules As will be seen later, it is possible to assemble a prefabricated module to one or more prefabricated modules. In addition, it is possible to assemble two prefabricated modules by means of at least two connecting pieces of the same type or of separate type so as to stiffen the assembly.

FIG. 10A illustrates in perspective the assembly of several prefabricated modules, and in particular of three open modules 200 ", of an open module 400, of an open module 900 and of a closed module M1, by means of plates link 30 and connecting brackets 40.

Of course, these same modules could be assembled with other connecting pieces comprising different shapes and light arrangements. Moreover, two modules of identical structure or not can be assembled by several plates or connecting brackets.

Of course, we can, in some cases, assemble two modules through a single plate or bracket. FIG. 10B is a schematic side view illustrating the right-angle assembly of two prefabricated modules M1, M2 through a connecting plate 30 (FIG. 5A) and a connecting square 40 (FIGS. 6A to 6C). ) especially.

The modules M1 and M2 are of the type illustrated in FIGS. 1A and 1B, the crosspieces and uprights having a rectangular profile of length e and width b. For the sake of clarity, only the crosspieces 103, 113 of the module M1 and the cross members 104, 114 of the module M2 have been represented. Since the thickness of the modules M1 and M2 is substantially equal to e (it can be greater if closure panels are provided), the left vertical edge of the crossmember 113 is located at a distance e from the left vertical edge of the crossmember 103. A vertical hole 414 may be formed in the cross-piece 113 and the light 41 of the connecting square 40 placed in correspondence with this hole 414. This vertical hole 414 is located at a distance substantially equal to 1 / 2b with respect to the vertical edge left of the crossbar 113, the light 41 being located at a distance equal to 1 / 2b relative to the angle of the connecting bracket 40. Figure 10D is a schematic side view illustrating the assembly in the same plane of two prefabricated modules M1, M2 through an upper connecting plate 30 and a lower connecting plate 30 '(of the type illustrated in FIG. 5A). The modules M1 and M2 are of the type illustrated in FIGS. 1A and 1B, the crosspieces and uprights having a rectangular profile of length e and width b. In this FIG. 10D, the vertical holes 414 and 415 respectively formed in the modules M2 and M1 are distinguished, these holes being distant by a distance substantially equal to b. FIG. 10C illustrates in perspective the assembly of several prefabricated modules, and in particular of a module 200 ", a module 600, a module 800 and a module 900, by means of plates 30 and Connecting brackets 40. Note that the connecting plates 30 allow the assembly of the modules 600 and 800 in the same plane, and the assembly of the modules 200 "and 900 in two perpendicular planes. Assembled modules are here of the same thickness.

However, it is possible to assemble two modules of different thicknesses in the same plane or in two perpendicular planes. Moreover, although the slots of the connecting plates and brackets 40 are not visible in FIGS. 10A to 10C, their shape and their arrangement can be chosen from those illustrated in FIGS. 5A, 6A to 6C or 7, for example (but not only) FIG. 14A illustrates the right-angle assembly of two modules 500 and 900, offset in height, by means of two connecting brackets 40. FIG. 14B illustrates these unassembled modules 500 and 900, a closing and bracing panel 550, 950 fixed on one of their faces being visible here. On these panels 550, 650, there are colored strips or markings corresponding to the crosspieces and uprights of the module 500, 900 respectively, these strips indicating the areas of contact and attachment of the modules 500, 900, and possibly where these modules 500, 900 can be drilled. The vertical band B500 of the module 500 thus corresponds to the location of the vertical inner sleepers 511, 512 of the module 500, and the diagonal band B900 of the module 900 thus corresponds to the location of the diagonal inner cross members 914, 915 of the module 900. Figures 12A and 12E show the mounting of two connecting plates 30 for example to assemble two prefabricated modules (not shown). In Fig. 12A, a first threaded rod 60 is inserted into the slot 31 of the plate 30 and into the slot 32 'of the plate 30', a nut 61 being screwed to each end of the first threaded shank 60. A second shank Thread 60 'is inserted into the aperture 32 of the plate 30 and into the aperture 31' of the plate 30 ', a nut 61' being screwed to each end of the second threaded shank 60 '. In Fig. 12E, a first threaded shank 60 is inserted into the aperture 32 of the plate 30 and into the aperture 32 'of the plate 30', a nut 61 being screwed to each end of the first threaded shank 60. A second shank threaded 60 'is introduced into the slot 31 of the plate 30 and into the slot 31' of the plate 30 ', a nut 61' being screwed to each end of the second threaded rod 60 '. The fixing means and the plates 30, 30 'are the same in FIGS. 12A and 12E. However, the plate 30 of FIG. 12A is rotated 180 ° along the y-axis in FIG. 12E. The same plate therefore has several laying directions along the x, y and z axes. It will be understood that for each assembly illustrated in FIGS. 12A and 12E, the threaded rod 60 passes right through a first module (not shown) and that the threaded rod 60 'passes right through a second module (not shown) intended to to be assembled with the first module, and that the plates 30, 30 'are placed on a separate face of the two modules to be assembled. Two modules can be assembled by implementing one of these assemblies (the assembly of two modules M1, M2 implementing the assembly of Figure 12E is shown schematically in Figure 17) or both montages at a time.

FIG. 12B shows three identical connecting brackets 40, 40 ', 40 "intended, for example, to assemble four prefabricated modules M1 to M4 shown in dashed lines in FIG. 13A. The modules M1, M3 and M5 are assembled in a same plane parallel to FIG. x, the modules M2 and M4 being assembled in a plane perpendicular (according to y) to the assembly plane of the modules M1, M3 and M5 A threaded rod 60 passing right through the prefabricated module M4 is introduced into the light 42 of the bracket 40 and in the slot 42 "of the bracket 40", a nut 61 being screwed to each end of the threaded rod 60. A bolt 62 'is introduced into the slot 41' of the bracket 40 'and is screwed into a bushing 63 'arranged in a non-through hole (not shown) formed in a crossmember or an upright (not shown) of the prefabricated module M 3. A bolt 62 is introduced into the slot 41 of the bracket 40 and is screwed into a sleeve 63 disposed in a non-through hole (not shown) formed in the same crossbar or upright (not shown) of the prefabricated module M3.

With respect to the assembly plane of the modules M1, M3 and M5, the axis B passing through the bushing 63 and the bolt 62 is located above the axis A passing through the rod 60, and the axis A is located above the axis C passing through the bolt 62 'and the sleeve 63'. Note that the module M5 of Figure 13A is connected to the module M1 by two connecting plates 30 and two connecting plates 30 ", the connecting plates 30 traversed by threaded rods being arranged symmetrically.The module M5 is connected to the module M3 by two connecting plates 30 'The connecting plates 30', 30 "are fixed to the modules by means of bolts associated with bushings. These connecting plates 30 ', 30 "are asymmetrical because of their position on the modules M1, M3 and M5, the arrangement of the slots and the fixing pins of the sockets The modules M1 to M4 are assembled by four brackets, only the brackets 40, 40 ', 40 "being visible in Figure 13A. The two brackets 40 and 40 "traversed by the threaded rod 60 (Figure 12B) are arranged symmetrically in Figure 13A, Figure 12C shows a connecting plate 30 and a connecting bracket 40 intended for example to assemble three prefabricated modules M1 to M3 shown in dashed lines in Figure 13B The modules M1 and M3 are assembled edge-to-edge in the same plane, the module M2 being assembled perpendicularly to the modules M1 and M3 A bolt 62 is introduced into each light 31, 32 of the plate 30, each bolt 62 being screwed into a separate socket 63 housed in M1 and M3 respectively A bolt 62 is inserted into the slot 41 of the bracket 40 and is screwed into a socket 63 housed in a blind hole in the module M3.

Figure 12D shows the assembly of two prefabricated modules through two connecting plates 30, 30 'located on either side of the modules M1 and M2 which are arranged one on the other. As regards the plate 30, a bolt 62 is introduced into each slot 31, 32 of the plate 30 and is screwed into a separate socket 63, a socket 63 being housed in a blind hole of the module M1 and the other socket 63 being housed in a blind hole of the M2 module. As regards the plate 30 ', a bolt 62 is introduced into each slot 31', 32 'of the plate 30' and is screwed into a separate socket 63, a socket 63 being housed in a blind hole of the module M1 and the another socket 63 being housed in a blind hole of the module M2. Note that the connecting plates 30, 30 'are not necessarily arranged symmetrically. 6.5 Method of Assembling Prefabricated Modules A first example of the method for assembling two prefabricated modules according to the invention has been described previously in connection with FIG. 5B. Another example is described below for the case where two modules 200, 200 'are assembled singing against edge (that is to say crosses against crossbeam) in the same plane as shown in Figure 15.

To do this, two pairs of connecting plates 30, 30 'are used in the example illustrated in FIG. 15, which are associated with threaded rods and nuts, as described with reference to FIGS. 12A and 12E. In this figure 15, only three of the four connecting plates 30, 30 'are visible. For the sake of clarity, the assembly steps are described for the single pair of connecting plates 30, 30 'located on the left in FIG. 15. The same steps are obviously implemented for the pair of connecting plates 30, 30 'on the right. In a first step, a first through-fixing hole is provided at the desired position on the outer bottom rail 204 of the prefabricated module 200 and a second through-fixing hole is provided at the desired position on the outer top rail (not visible) of the prefabricated module 200 '. A threaded rod whose length is greater than the thickness of the prefabricated module 200 is then inserted into the through-fixing hole formed in the outer bottom cross member 204 of the module 200. Once housed in this through-fixing hole, the ends of the threaded rod protrude from each side of the outer bottom cross member 204 of the module 200. An end of the threaded rod is introduced into the slot 31 of the connecting plate 30 and the connecting plate 30 is positioned so that the through hole arranged in the outer upper crossmember of the module 200 'is fully visible in the inclined light of the connecting plate 30. Once this step is performed, the threaded rod is introduced into the inclined hole 32 of the connection plate 30 and into the hole through the upper outer rail of the module 200 'until the ends of the threaded rod protrude from each side of the tr high outside shower of 200 'module. It is therefore possible to position the connecting plate 30 'on the threaded rods symmetrically (or non-symmetrically) with the connecting plate 30. Therefore, the connecting plates 30, 30' overlap the lower edge of the module 200 and the upper edge of the module 200 ', and nuts can be screwed to the ends of the threaded rods so as to immobilize the connecting plates 30, 30' on the modules 200, 200 'and assemble these in compression and tension.

The same steps are implemented when fixing two prefabricated modules located in different planes, especially in the case of assembly of angle modules, or when the fastening means do not require through holes but only blind holes, or when the fastening means require a combination of through holes and blind. The connecting pieces of the invention have at least one rectilinear or non-rectilinear light, other than a circular hole, to be able to adapt these connecting pieces to approximate piercings. It may therefore be necessary to manipulate a connecting piece so as to match the fixing holes with each of the lights in such a room.

In other words, this or these lights make it possible to adapt the connecting pieces to implantation of bushings, drilling or stems that would be approximate. To do this, since a threaded rod is in particular implanted in a hole which passes through an amount of a first module and is introduced into a slot of a connecting piece, simply move the connecting piece around this threaded rod to match the other lumen of the connecting piece with another fixing hole which passes through an amount of a second module to be assembled to the first module. It should be noted that the implementation of such connecting pieces does not necessarily require having mounting holes disposed symmetrically on the uprights and / or crosses of the modules that are to be assembled. The mounting holes drilled in the uprights and transoms of the modules can therefore be offset in height in particular. The shape of the lights makes it possible to recover the possible offsets due to the approximate drilling of the fixing holes. Thus, the assembly device of the invention allows flexibility and freedom of assembly of the modules on the site that do not allow the techniques of the prior art, and in particular that described in US Patent 6,014,842 discussed previously and in which the modules are pre-drilled. In FIG. 15, the dimensions of the closure and bracing panels 250, 250 'are chosen so that the uprights and external cross members of the modules 200, 200' are invisible once the panels 250, 250 'are fixed on the modules. 200, 200 '(these rectangular panels are shown in part in this figure 15). The right and left connecting plates 30 come into contact with these panels 250, 250 '. FIG. 16 illustrates examples of combinations of fasteners used to assemble two modules M1 and M2 by means of connecting plates 30, 30 ', 30 ".The two connecting plates 30 are fixed via a) of FIG. a through bushing 63 associated with two bolts 62 and b) a threaded rod 60 associated with two nuts 61. The two connecting plates 30 'are fixed via a) a through bushing 63 associated with two bolts 62 and b) two non-through bushings 63 each associated with a bolt 62. The two connecting plates 30 "are fixed by means of a) a threaded rod 60 associated with two nuts 61 and b) of two associated non-through sleeves 63 each is a bolt 62. 6.6 Examples of assembly of prefabricated modules Figures 8 and 9 show different (non-exhaustive) possibilities of assembling between several prefabricated modules, in this case two, three or four. For the sake of clarity, the assembly devices (connecting plates and screws) have not been shown. The prefabricated modules can be chosen from those illustrated in Figures 1 to 4B, but not only. Figure 8 shows different assemblies of prefabricated modules in two dimensions (8A, 8B, 8D, 8E, 8F, 8G, 8I, 8K, 8L, 8M, 8N) or three dimensions (8C, 8H, 8J). Two modules can be assembled at right angles, their upper edge being located in the same plane (8D, 8I) or in two separate parallel planes (8H). Similarly, the prefabricated modules can be assembled in the form of a cross, which allows the separation of rooms within a dwelling (8A, 8B, 8E, 8G, 8J). Three prefabricated modules can also be assembled so that their upper edge is located in separate parallel planes (8C) allowing the establishment of openings (doors or windows for example).

FIG. 9 represents other possible assemblies (not exhaustive) between several prefabricated modules. In particular, the assembly of an external upright or cross member of a module on an internal diagonal cross member of another prefabricated module is shown (9F). This assembly allows for example the construction of a roof.

An assembly of modules forming a staircase is also possible (9B, 9D). One can also consider the assembly of modules to form a floor (9E). In addition, storage spaces such as cupboards or shelves can be easily created (9C). It is understood from these figures 8 and 9 that the assembly of such prefabricated building modules can be done in all directions and thus allows the realization of floors / floors, roofs, ceilings, facades, partitions, gables, etc. 6.7 Examples of buildings designed from assembled prefabricated modules Figure 11A shows schematically and partially an example of a building constructed according to the modular construction principle of the invention. To do this, prefabricated modules are assembled, for example on a concrete slab (not shown), in three dimensions so as to constitute exterior facades, interior walls, floors, gables, beams and roofs. As described above, the prefabricated building modules are assembled side by side in the same plane or perpendicularly by assembling an upright or an internal or external cross member of a module with an internal or external jamb or cross member of a another module using at least one connecting piece associated with fastening means (bolts, dowels, bushings and / or threaded rods). The holes formed in the uprights and crosspieces of the prefabricated modules to house the fastening means can be drilled on the site, which allows to undertake a site without delay. It will be noted in FIG. 11A that an out-standard module 71 has been implemented in the design of the floor 70 and that the runners 72 are provided at the junction of the walls 74 and the lower parts of the roof 73.

Another example of a building made according to the modular construction principle of the invention is shown schematically in FIG. 11B. It will be noted in this FIG. 11B that an out-of-standard module 71 has been implemented in the design of the roof 73 and that the runners 72 are provided, in particular at the junction of the wall 74 and the roof 73.

These examples of construction are based on the implementation of prefabricated modules assembled through the connecting pieces illustrated in Figures 5 to 7 in particular, but not exclusively. 6.8 Other aspects and variants The distance between the two lights (as well as the dimensions of the lights) of a connecting piece is chosen as a function of: the section of the uprights and crosspieces of the prefabricated modules to be assembled, and / or the destination of the structures and / or the nature of structures (metal, wood or other). The angle of inclination and the distance between the two lumens of a connecting piece is chosen according to the degree of compression desired. For the construction of a wall from prefabricated modules, the assembly in tension is not necessary since such a wall works compression. The implementation of connecting plates with two circular holes is therefore sufficient for the stability of the wall, but in this case any modification of the wall (drilling a door or window, enlargement) requires a structural recovery. In addition any action on a possible impermeability to air is impossible (non-contiguous modules, dilations, cracks). The combined assembly in traction and compression of several modules according to the invention makes it possible to build a sail beam and not a wall, without price impact. The prefabricated modules of the invention have for example a thickness of 5 cm or 10 cm. Depending on the thickness of a first module, the inner structure of the second module to be assembled to the first module must be adapted as well as the distance between the connecting piece intended to assemble these two modules. The fact that the assembly of prefabricated building modules is done by an assembly device accessible from outside the modules allows easy handling by an operator. It is also relatively easy to remove a module without jeopardizing the strength of the assembled structure according to the principle of the invention. This also makes it possible to make modular construction over time.

It is thus possible to replace or repair a defective module. In addition, because of the varying thickness of the modules, the thickness of the floors may be different from the thickness of the walls. Such a modular construction solution based on an easy to install and assemble construction module is advantageous in that it requires little or no finishing and cutting.

Standard modules manufactured in advance and stored at material traders can be supplied and implemented on site as needed. The joineries available in the trade can be framed with such prefabricated modules which thus define an external framework, the new assembly becoming a module in its own right. The assembly of these prefabricated modules can be simulated through software that allows the design of custom buildings. This software can implement a database comprising various so-called standard building modules and also allows the design of non-standard modules. The standard modules may be rectangular, triangular, ridge (such as the elements 72 of Figures 11A and 11B) or sand pit for example. The implementation of such standard modules notably allows optimized packaging and transport, the setting in production in advance and without any known destination of building sites. It goes without saying that many modifications, remaining within the scope of the present invention, can be made to the assembly principle and to the structure of the prefabricated modules which have just been described. Thus, the fastening means may be any other fastening means equivalent to a combination of bolts and nuts. In some cases, the outer and inner walls of the assembled modules can be covered with a covering function of the desired aesthetics. The construction technique of the invention is particularly suitable for the construction of buildings: 30 - habitables (houses, collective dwellings, extensions, offices, verandas, industrial premises and public facilities for example), the building module implemented in this frame that can be closed and braced on at least one of these faces, or - non-habitable (garden huts, scaffolding, steps, formwork, walkways for example), the building module implemented in this frame can be opened or closed and braced (by a cross-shaped element of St. Andrew on at least one of these faces). The principle of the invention may further be applied to building sets. In this context, it is possible to apply to the faces of the building modules colors corresponding to the crosspieces and uprights, and which make it possible to indicate to the players and / or constructors how these modules can be assembled, and possibly in which places these can be drilled. The connecting pieces can, in this application, be wood, plastic or metal for example.

The assembly of the modules for use in the building or as part of a construction game can be performed without resorting to a previously generated assembly plan. 6.9 Prefabricated Building Module Variant Figure 25A is a sectional view of a prefabricated building module according to an alternative embodiment. This module M10 comprises an outer frame O formed of uprights and crosspieces, two closure panels PF1, PF2 and an inner insulation I. A waterproof membrane, or vapor barrier, PV is disposed between the closure panel PF1 and the insulation I, and comes to cover the four slices (vertical and horizontal) of the M10 module. To do this, this vapor barrier PV is unwound (and preferably fixed) on one face of the frame of the module M10, then the closure panel PF1 is fixed on the frame of the module M10. The vapor barrier PV is held in position on the slices of the module M10 by fixing its ends, for example stapling, on the other closure panel PF2, without completely covering the latter. A groove R is provided on the outer edge of the outer frame O of the module M10, halfway between the closure panels PF1 and PF2. In this groove R is placed a self-inflating joint J. When the module is not assembled as in FIG. 25A, the width of the joint J is smaller than the width of the groove R, and its height is greater than the depth of the groove. groove R. The vapor barrier PV is arranged so that it compresses the joint J which pushes the vapor barrier PV. The membrane is then spaced a few millimeters from the edge of the module M10. The vapor barrier may be made of PVC for example, or any other suitable material.

FIG. 25B illustrates the assembly of the module M10 with an identical module M10 'in the same plane, that is to say singing against edge. The assembly of the modules M10 and M10 'by means of a connecting device as described above or subsequently, allows, under the pressure of the assembly device and under the pressure of self-inflating joints J and J' (which have expanded in the corresponding groove, the height of the joints J and J 'facing has been reduced and their width has increased to correspond to the depth of the corresponding groove), the continuous contact of the PV membrane of the module M10 with the PV 'membrane of the M10' module. Thus, the vapor barrier PV, PV 'constituted by the assembly in a plane of the two modules M10 and M10' is continuous and inaccessible. In fact, neither the PV membranes, PVsituated at the surface of the contacts of the modules M10 and M10 ', nor the PV, PV' membranes situated between the closure panel PF, PF 'and the insulator I, I' respectively are only accessible when the M10 and M10 modules are assembled.

Such an approach thus makes it possible to treat the water and air seals of modules thus assembled. In addition, in the case where the framework of the modules is wood, it is not necessary to implement a fungicidal and insecticidal treatment of the wooden parts of the framework, insofar as these parts are enclosed by the vapor barrier and are therefore no longer in contact with the air.

Figure 26 illustrates the assembly of two modules M10 and M20 at an angle, the module M10 being identical to that shown in Figure 25A.

The module M20 comprises a vapor barrier PV "which extends on the inside of the closure panel PF1", on the edge of the module M20 and on an outer part of the closure panel PF2 ".The assembly of the modules M10 and M20 allows, under the pressure of an assembly device and under the pressure of the self-inflating seal J of the module M10 against the vapor barrier PV "of the module M20, the continuous contacting of the vapor barrier membranes PV and PV" of the modules M10 and M20 respectively The addition of a PL plate on the edge of the module M20 makes it possible to prevent access to the PV and PV vapor barrier membranes and to protect them, once the modules have been assembled. In other words, the vapor barrier PV and PV "is also continuous and inaccessible for this type of assembly of angle modules.This approach makes it possible to treat watertightness and airtightness. Fasteners with three or more attachment points Next, the assembly of several prefabricated building modules, as described above, is described by means of one or more devices or assembly means each comprising minus three fixing points As previously described, the means used for the compression assembly of the modules are the same as those used for the tensile assembly of these modules. The coupling means are mounted on the outside of the modules on one or both sides of the modules and are provided with connecting means comprising a plurality of apertures (or attachment points) in which one comes engage fixing means. The fixing means which pass totally or partially through the modules, in pre-drilled or non-pre-drilled holes, make it possible to fix the connection means on the modules and to assemble the latter. In the illustrated examples, the connecting means are circular plates which have at least three slots (or attachment points) of oblong shape. Other forms of platinum (diamond, triangle, square) and lights can be implemented, of course. Figure 18 illustrates the assembly of five modules M1 to M5 through two plates or connecting plates P1 and P2.

More specifically, the modules M1 to M4 are assembled in tension and compression through the plate P1. Two fixing points are provided on each of the modules M1 to M4. The arrangement of the eight lights of the plate P1 and the rotation thereof around its center O in the direction of clockwise makes it possible to tighten (or compress) the modules M1 to M4 to each other.

Figure 20A is a detail view of the plate P1 which is circular in shape and is preferably made of metal. Platinum P1 comprises eight oblong slots, whose centers are located on a circle of center O and radius R, at the intersection of the circle of radius R and the tangent T to this circle.

Each axis aL passing through the center of each light L has an inclination with respect to the tangent T equal to 10 ° in this example. This angle may vary depending on the effectiveness of the desired compression. It is noted that the distances between the center O and the two points of intersection of the tangent T and the contour of the light L are not equal. In addition, the axes aL of the lights L are not parallel to the tangents T. Therefore, when a rotation movement of the plate P1 around its center O in the direction of clockwise, is clamped , that is to say, it tends to bring the fixing points which pass through the lights L towards the center of the plate P1 (and therefore we tend to bring the modules M1 to M4). A rotational movement of the plate P1 around the center O in the counterclockwise direction causes a loosening (it tends to move away from the fixing points which pass through the lights L towards the outside of the plate P1). The modules M3 to M5 are assembled in tension and compression through the plate P2. The M3 and M4 modules have an attachment point and the M5 module has two attachment points. The arrangement of the four lights L of the plate P2 and the rotation of the plate P2 around its center O in the direction of clockwise makes it possible to tighten (or compress) the modules M3 to M5 to each other. Figure 20B is a detailed view of the plate P2 which is intended to connect up to four modules in the same plane, singing against singing. The plate P2 comprises a first portion P2A intended to be placed on an outer face of the module M4 and comprising a light L, a second portion P2B intended to be placed on an outer face of the module M3 and comprising a light L, and a third portion P2C intended to be placed on an outer face of the module M5 and comprising two lights L. Figure 19 illustrates the assembly of three modules M6 to M8 in traction and compression through the plate P3. Each module M6, M7, M8 includes a single point of attachment. The arrangement of the three lights L of the plate P3 and the rotation thereof around its center O in the direction of clockwise makes it possible to clamp (or compress) the modules M6 to M8 to each other. Figure 20C is a detail view of the plate P3 which is intended to connect up to three modules in the same plane, singing against singing. As illustrated in FIG. 19, the plate P3 comprises a first portion P3A intended to be placed on an outer face of the module M6, a second portion P3B intended to be placed on an outer face of the module M7 and a third portion P3C intended to be placed on an outer face of the M8 module. It should be noted that the center of the lights L disposed on the modules M6 and M7 are on the same circle of radius R and center O, whereas the center of the light L 'disposed on the module M8 is on a circle of center O and radius R ', smaller than radius R. In a particular embodiment described in relation to FIGS. 22A, 22B, 23A, 23B, 24A and 24B, two identical plates P2, P'2 are superimposed (FIG. 20B) on one another to assemble two or more modules. These two plates P2, P'2 each comprise a first face (a) and a second face (b).

FIG. 22A illustrates the first face (a) of the stage P2 (which is called P2a) and FIG. 22B illustrates the second face (b) of the stage P2 (which is called P'2b). As shown in FIG. 23, if the platen P2 is rotated in a clockwise direction when it is resting on its face (b) on at least two modules, these modules are tightened. If the platen P2 is rotated in the counterclockwise direction when it is resting on its face (a) on at least two modules, these modules are tightened. When these two plates P2 and P'2 are superimposed on one another (that is to say when we plate the face (b) of the plate P2 on the face (a) of the plate P'2, and that the face (a) of the plate P'2 is placed on the modules to be assembled), before applying any rotation, the oblong slots of the two plates P2 and P'2 intersect as illustrated in Figure 24A. When rotating in one direction or the other, the oblong slots of the two plates P2 and P'2 tend to overlap (Figure 24B). In other words, in general, two identical plates superimposed symmetrically on one another, contribute to clamping the fixing means regardless of the direction of rotation of the two plates, and thus block any loosening movement. It is of course possible to superimpose two plates on each side of the modules to be assembled (in this case, it implements four plates to assemble the modules). Figure 21A is a front view of a connecting plate which combines the attachment points of the connecting plates of Figures 20A and 20B. Figure 21B is a front view of a connecting plate which combines the attachment points of the connecting plates of Figures 20A and 20C. FIG. 21C is a front view of a connecting plate which combines the fixing points of the connecting plates of FIGS. 20A and 20B and which comprises irregularities on its contour, in the form of four uniformly distributed semicircular E notches these notches E being intended to facilitate the rotation (manual or by means of a tool) of the plate during the assembly of several modules. In an alternative, the plate has one or more projecting elements on its contour to facilitate the rotation of the plate.
