Description

The present invention relates to a prefabricated wooden building which is suitable as an independent construction or annex to an existing construction. It relates more specifically to a prefabricated building that can be used for offices and / or housing and / or school buildings. The requirements relating to the protection of the environment and sustainable development are becoming more and more stringent and wood is becoming more and more essential as a construction material, since it is a material generated naturally and therefore renewable, which it requires. has a long lifespan, and can easily be recycled. Wood also has excellent mechanical strength characteristics and is well suited for construction, such as office or industrial buildings. In addition, the requirements for thermal insulation and sound insulation are constantly increasing and the wood is well suited for the construction of buildings for both residential and office complexes that must meet new standards. , since it itself has a good thermal insulation coefficient and also makes it possible to easily produce hollow structures which can be filled with thermal and / or sound insulating materials. When we talk about wood, we understand of course wood as such, but also wood-based composite products, such as glued laminates, laminates, OSB panels, MDF (medium density fiber) and others.

STATE OF THE ART Wooden constructions of various types are known. Some are built on site; others consist of elements prefabricated in the workshop and assembled on site.

It is understood that the pressure on costs is pushing towards BE2019 / 5680 an increasingly advanced prefabrication in workshops.

One of the advantages of prefabrication of wooden elements is that, with certain precautions, the arrangement of the rooms can be changed relatively easily in this type of construction.

See in particular document BE2013 / 0226. Aims of the Invention

The present invention now aims to provide a prefabricated building which allows not only the displacement of internal walls for the modification of the interior layout but also the displacement or replacement of middle walls.

Another object is to provide a building of the aforementioned type which allows an enlargement or a narrowing of the volume as well as of the arrangement of the various boxes and finishes.

Another object of the invention is to provide a building of the above-mentioned type for which the construction is largely prefabricated in the workshop and the assembly of the prefabricated elements is done quite easily on site.

Brief Description of the Invention The invention consists of a prefabricated wooden building comprising a basic structure of the post-beam type, common and / or external walls, optionally one or more pianchers in caissons and partitions or partitions, the party and / or exterior walls consisting of a sub-structure or frame comprising several uprights and spacers arranged at regular distances, closing panels being assembled with the frame, namely the uprights and / or the spacers, at the using metal legs, to form a closed wall.

In the case of a party wall, the frame "& BEF2019 / 5680 can be fitted with closing panels on each side.

In the case of an outer wall, the outer face will be provided with closing panels or boxes covered with a material, such as a sheet of synthetic material, impermeable to water.

They can then be covered with siding materials.

It is understood that the volume between opposite closure panels can be filled with thermal and / or sound insulating material.

Advantageously, the closure panels are clipped into the frames.

Of course, a common or even exterior wall can be easily moved, added, removed within a given volume.

It is also possible to replace an existing wall with another, in particular to replace a completely closed wall with a partition which has a window or vice versa.

Advantageously, the uprights of the frame are connected by spacers assembled with the uprights of the frame by dovetail assemblies.

In practice, studs integral with the ends of the spacers slide in grooves made in the uprights of the frame.

According to an advantageous embodiment of the invention, the frame is fixed to the ceiling by metal tongues corresponding to grooves made in the ceiling.

The space between the frame and the ceiling is advantageously blocked by a plug of insulating material, in particular of rcche wool, On the floor, the wall can be fixed in the same way, It is also possible to provide for the placement of the wall on a rail orientation which immobilizes the wall in the direction perpendicular to its separation surface.

Clogging of the seal formed by an insulating material is recommended.

The connection of a wall to a post of the basic structure can be done by fixing an upright of the substructure to the post or possibly by means of a BE2019 / 5680 spacer module connecting the sub- structure from wall to post.

The connection of a wall perpendicular to another wall can be done in the same way, the connection then being made on the closure panel if there is no post at the junction.

The closure panels advantageously consist of two plaster panels screwed onto a wooden panel, in particular an OSB panel.

This structure makes it possible to give rigidity to the wall while providing it with sufficient fire resistance and acoustic resistance according to the standards in force.

In order to further improve the finish, the surface (s) of the wall facing the interior of the building can be covered with a finishing plaster panel or another suitable material, possibly with lathing and / or clipping.

For the surfaces facing the outside of the building, it is possible to provide caissons secured to the substructure or to the main column-beam structure, said caissons being coated with a waterproof sheet on their face oriented towards the outside.

Said boxes advantageously comprise a thermal and / or sound insulating material which improves thermal and / or sound insulation.

The joints between boxes are advantageously sealed with an insulating material.

An outer face can then be covered with cladding panels, possibly perforated.

Said caissons are advantageously mechanically fixed from the outside thus allowing the caisson to possibly play a role of overall bracing of the building.

In order to prevent the infiltration of water behind the cladding techniques and then between the boxes forming the outer wall, it is necessary to provide sealing joints.

As such, it is possible to glue a waterproof adhesive strip so as to cover the joint between two boxes.

However, it is also possible to provide double seals to protect the BE2019 / 5680 horizontal joints: a first seal may consist of a strip of waterproof material secured to a first panel, which protrudes on the lower edge of the box

5 so as to partially cover a second box arranged in the same plane, but below the first.

A second seal consists of a strip of waterproof material inserted in a groove made in the lower edge of the first box and resting on the upper edge of said second box.

This edge can still be chamfered to allow the flow of water that would have infiltrated the junction.

As regards the vertical junctions, one can also provide two vertical joints each consisting of strips of waterproof material integral with each of the adjacent boxes and overlapping, one of the two joints being arranged near the outer surface of the boxes and the the other being arranged at a distance from the first, in the gap between two boxes.

This way of proceeding no longer requires bonding on site,

allows for workshop preparation and has proven to be particularly effective.

In view of all of the foregoing and as will be further described in connection with an exemplary embodiment below, those skilled in the art will easily understand that the construction system according to the invention is particularly flexible and even makes it possible to replace or move common or external walls.

According to a preferred embodiment of the invention, the prefabricated building comprises a floor and / or a light ceiling which allows the volume and / or surface modifications made possible by the construction system of the walls described above.

Advantageously, the lightweight floor consists of juxtaposed modules which extend over a length corresponding to the distance between two beams of the basic post-beam structure and over a suitable width.

Each module has two opposing and parallel C-beams BE2019 / 5680 interconnected by spacers, preferably at the upper part, a fire-resistant membrane being deposited on the lower part of the C-beams, preferably on a mattress of material. insulating, such as mineral wool, especially rock wool. The spacers can be screwed and / or glued to the C-beam heads of the modules. A thermal and / or sound insulating material can also be deposited on the fire-resistant membrane. Plaster or other suitable material finishing panels can be fixed to the lower part of the modules, possibly by means of a lath or clipping means to form a ceiling. A "floating" false floor is placed on the upper face of the modules, via pads of resilient material. This type of floor is intended to receive a finish, such as a tile or a parquet or another type of coating.

The fire-resistant membrane advantageously consists of two plaster panels fixed to an OSB panel for the sake of rigidity. Those skilled in the art will easily understand that the fireproof membrane separates the internal volume of the modules into two parts, an upper part and a lower part which can be used to accommodate special techniques.

The heads of the C-beams, in practice the top joists, protrude on the end section and rest on the beams of the base structure.

This type of floor made up of light modules allows the movement of the staircase hopper or a vertical or other technical shaft. The stairs can be found sometimes in a corner of the house, sometimes in the middle of a room. In addition, it allows the integration of the distribution of special techniques, including water, electricity, landfills, ventilation etc., for both the lower and upper floors.

The described floor has good fire resistance according to BE2019 / 5680 the standards in force and is particularly resistant despite its lightness. In addition, it guarantees good acoustic performance, following the separation effects of the various elements. A building according to the invention naturally has a roof. It is possible to provide a flat roof, either mounted on site, or prefabricated in the workshop, or a sloping roof, preferably with two sides. According to a preferred embodiment, the two-sided roof consists of two-sided roof modules prefabricated in the workshop. Such a prefabricated two-sided roof module comprises at least two self-supporting boxes intended to form the two sides of the roof, said self-supporting boxes being interconnected by at least one or more, preferably two, articulation means, such as hinges, arranged so that the axis of rotation is between the two upper adjacent edges of the two self-supporting boxes. Such a roof module can easily be transported "flat" in a space-saving manner, thanks to the articulation of the two self-supporting boxes between them. During placement, it is possible to lift all of the two articulated boxes, for example by the axis of rotation of the articulation means or along the axes of the centers of gravity of each of the two sides, and place the assembly on a construction to be covered, without it being necessary to provide a support structure, such as purlins or a more complex structure, such as a frame, the self-supporting boxes forming the sections of the roof to be built.

In order to stiffen the assembly, it is of course possible to provide ties or tie rods, possibly rolled up, which connect the two sides of the roof to each other and reduce the horizontal forces in the direction of a spacing thrust acting on the supports, in this case the walls of BE2019 / 5680 constructions to be covered. The boxes are advantageously made of a wooden frame, possibly stiffened, for example by spacers. They may comprise an outer surface covering panel, such as for example a rain barrier panel, for example made of wood fibers, and an internal surface covering panel, such as for example a plasterboard, a wood panel and / or an airtight film.

We can, of course, push the prefabrication to cover the inside of a finishing panel, such as a plaster or fiber-plaster panel.

The boxes advantageously include thermal and / or sound insulation as well as one or more airtightness and / or humidity sheets, depending on the requirements and standards of the construction in question.

Detailed Description of the Invention In order to facilitate reading, the same elements bear the same reference marks in the various figures. The invention relates to a construction or to a prefabricated building 100, preferably in wood, comprising a base structure 101 of the post-beam type known per se, party walls or in external counter-partitions 103, one or more floors. 105, removable partitions or partitions (not shown) and, optionally, a roof

107.

One of the essential characteristics of the invention lies in the fact that the external and / or party walls are removable, movable and / or replaceable, so as to form a particularly scalable construction.

The various elements of a construction or building according to the invention are described in detail below with reference to the various attached figures.

Figure 2 shows a cross section through a wall

103. Common walls and / or external partitions

103 have a substructure which is made up of several BE2019 / 5680 uprights 131 arranged at a regular distance from each other, separated by spacers (not shown). Closure panels 133 are clipped onto the substructure 131 using clips. It is also possible to provide a layer of rock wool forming a seal between a closure panel 131 and the substructure. This gasket is intended to damp vibrations to increase sound insulation and to protect the substructure 131 against fire.

A closure panel 131 advantageously consists of an OSB panel 141 on which are assembled, in particular by screwing, two plaster panels 143 and 145, also called plasterboard panels. the closure panels can be applied on one side of a party wall 103 or on both sides thereof.

In order to perfect the surface, in particular when it is an internal face of a dividing wall or external counter-partition, it is possible to apply, optionally by means of a lathing, finishing panels 149. Those -ci can consist of one or two superimposed layers. In the case where a party wall 103 is arranged on two sides of a post of the base structure 101, the finishing surface formed by the finishing panels 149 can cover and thus hide the base structure 101, It will also be noted that in the exemplary embodiment of FIG. 2, the two faces of the wall are covered with finishing panels 149. It is understood that in the case of an outer wall, the inner face can be prepared as mentioned above and the external face is different (see below).

The space between the various elements of the substructure 131 and the closure panels can be at least partially filled with mineral wool, in particular with BE2019 / 5680 rock wool 151. FIG. 3 shows an external wall.

The internal face is arranged as described in relation to FIG. 2 and the external face carries closing boxes 191 filled with insulating material 197 and closed by means of a closing panel.

There can be seen an insulating seal 199. FIG. 4 shows a corner arrangement of a party wall, around a post of basic structure 101. In this case, an intermediate wall element can be provided to complete the junction with the post 101. The intermediate wall element is identical to the wall, except for the fact that the distance between uprights 131 of the substructure is shorter.

As can be seen, the finishing panels 149 cover the post on the outside; the finishing panels 149 meet at an angle and at least partially covering the spacer elements, within the angle formed by the wall described.

Figure 5 shows a corner arrangement of a party wall.

There are the same essential elements as in the case of the previous figures.

The corner 142 is formed by OSB panels 141 assembled in a corner onto which plaster panels 143 and 145 are each screwed. The corner element is clipped onto the uprights 131 of the sub-

structure.

As mentioned above, when the wall in question is applied in the outer wall, the outer face is coated with outer boxes 191 which can accommodate the cladding.

The boxes 191 comprise a frame 193 closed on at least one side by a closure panel 195, and filled with thermal and / or sound-insulating material 197. At least part of the frame and the closure panel are covered with a sheet. waterproof.

A gasket of insulating material 199 can be inserted between two boxes in order to avoid the creation of thermal bridges.

A facade cladding 201 known per se can BE2019 / 5680 be applied to the closing panels 195. In order to prevent the infiltration of water between and / or into the caissons, at least one seal 203 is inserted in the side edges. and lower boxes 193. The upper part of the frame 193 is advantageously chamfered so as to allow the flow of water which could have entered it.

The lower seal 203 rests on the chamfer.

At the location of the side joints, these are arranged so that they overlap.

This arrangement makes it easy to achieve effective sealing, prefabricating as much as possible in the workshop and without having to resort to bonding on site.

To further improve the seal, a second seal can be provided at the outer surface of the closure boxes.

According to the same principle as that stated above, the seal or the lower flap comes to rest against the outer surface of the lower box and on the sides, the joints of the adjacent boxes overlap.

The following description relates to a floor intended for a prefabricated wooden construction, which, moreover, allows extensive scalability, namely that said floor is modular and allows removal, movement within a building and / or replacement of floor modules.

This type of floor thus makes it possible to modify the position of the staircase hopper or of a vertical technical shaft.

In addition, it allows the integration of distributions of special techniques, both for the lower floor and for the upper floor.

It must obviously also meet the requirements of mechanical strength, fire resistance and guarantee adequate thermal and sound insulation.

According to an advantageous embodiment, a floor module consists of two longitudinal C-beams 211, 2117 oriented parallel with the flanges 215,217 of one BE2019 / 5680 facing the flanges 215 ', 217 "of the other.

Each 211.211 "C-beam may consist of a 219.219" OSB web to which the upper 217.217 "and lower 215.215 'flanges are glued. The two C-beams are connected by spacers 221 fixed by their ends to the upper flanges 217.217 This assembly can be done by gluing and / or screwing.

The height of the web of the C-beams influences the maximum span of the floor.

Heights of for example 300mm, 400mm or 5C0mm can be provided for spans of more than 6m depending on the applications.

These floor modules rest at their ends on the beams of the base structure of the post-beam type.

Preferably, the head of the C-beam, in fact the upper joist, is housed in a recess made in the beam of the base structure (column-beams). In a preferred embodiment, a fire barrier 223 rests on the bottom flanges 215.215 ", preferably via a mineral wool gasket 225.225". The fire barrier advantageously consists of an OSB panel 227 on which are screwed two plaster panels 229,231, Furthermore, a thermal and / or sound insulation 233 can still be deposited on the cut-off barrier.

fire.

As can be seen, the arrangement of the floor according to the invention allows the placement of special techniques, electricity, water, vacuum discharges included just under the floating floor.

Air distribution and / or ventilation techniques can be arranged in the space under the fire barrier.

A floating floor is advantageously placed on pads 237 of resilient material.

Said floating floor 235 can consist of two OSB panels assembled with staggered joints and BE2019 / 5680 be coated with a 239 finish as desired.

On the underside serving as a ceiling, it is possible, if necessary, to fix a vapor barrier membrane, but also finishing panels, such as plaster panels 241, possibly by means of a lathing 243. A construction according to the invention must obviously also include a roof.

This can be a flat roof or the like.

Figures 10-12 relate to a gable roof.

Figure 10 shows, in a schematic perspective view, a roof element 107 according to the invention.

The roof element has two self-supporting boxes, 301 and 303, which are assembled by two hinges 315 and 317 whose axis of rotation is located substantially between the adjacent upper ridges of the two self-supporting boxes 301,303. Each self-supporting box comprises a cover panel for the external surface, 319 and 321. The self-supporting boxes each rest on a base structure and are retained by a stop integral with the latter or formed in the latter.

An insulator 345 (see Figure 12) is advantageously inserted between the bearing face, 323 and 325, of each of the boxes, 301 and 303, and the corresponding bearing surface, 324 and 326, of the supporting structure.

In order to counterbalance the horizontal forces tending to separate the roof sections, and therefore the self-supporting caissons, under a load, such as wind and / or snow, it is possible to provide ties, possibly rolled up, 327, 329. For the assembly of a roof, we can therefore place prefabricated modules 107 one after the other, and we can optionally connect them with fixing means known per se.

The roof thus formed can still be covered with a sealing sheet known per se (see figure 11) and then be covered with tiles or a usual roof covering 365 (see figure 11).

Figure 11 shows in detail the roof ridge folded as in Figure 10 and flat, for transport and / or storage. We can see the ends of the two self-supporting boxes 301 and 303 connected by a hinge 317 whose female elements are screwed onto the corresponding transverse sides of the boxes, and whose axis of rotation is located substantially between the two upper adjacent edges of the two self-supporting caissons 301 and 303. The sealing at the location of the articulated junction of the two caissons can be prepared in the workshop so that it is sufficient to complete the coverage of said junction on site, if necessary. The boxes advantageously comprise joists 332 interconnected by the transverse elements 341, 349 and

351. The boxes can also be stiffened by additional spacers, if necessary. The hollows thus created are filled with thermal and / or sound-insulating material 355. The outer face of the caissons can be covered with a roof covering panel 357. The internal face of the caissons can be covered with a front cover panel. internal or simply a sealing sheet 367. It is understood that these boxes, their outer face and their face facing inwardly can be produced with precision and in good safety conditions in the workshop. The assembly of several modules to form the roof will be done on site. When the roof is assembled, it can be covered with a usual waterproofing sheet 361 and the roof can be covered with tiles, slates or any other roofing material known per se 365. As can be seen in FIG. 11 , the upper transverse elements 341 on which the hinges are screwed are inclined relative to a plane perpendicular to the plane of the outer surface of the box and comprising the axis of articulation of the two boxes at an angle a which BE2019 / 5680 corresponds to the angle of inclination of the roof so as to allow the desired angular displacement of the two self-supporting boxes, one relative to the other.

It will be easily understood, in particular from FIG. 11, that a prefabricated roof element according to the invention "opens" or "unfolds" easily, thus allowing relatively space-saving storage and / or transport, ie. in a predominantly flat position.

IO For assembly, it suffices to lift the prefabricated module by the axis of the hinges or near them in order to allow the “folding” or the “closing” of the prefabricated roof module and to put it down and fix, by example by screwing 377, 378 on the base structure. We can then drop the next module etc.

As a variant, the prefabricated modules can be lifted by lifting fixings arranged along the axes of the centers of gravity of each of the panels.

As can be seen in Figure 10 and more particularly in Figure 12, in order to form horizontal bearing surfaces 323 and 325, the lower transverse elements 349 and 351 are inclined at an angle B with respect to a perpendicular plane the external cover plane of the self-supporting box, which corresponds to the angle of inclination of the roof.

As shown in Figures 11 and 12, the internal face of the boxes is covered with finishing panels such as plasterboard panels 371, in particular by means of a suitable lathing 373.

It is clear from the above description that the type of roof according to the invention makes it possible to push prefabrication in the workshop very far with a minimum of tasks being devolved on the construction site.

In addition, the prefabrication work can be done BE2019 / 5680 in good safety conditions in the workshop and the tasks remaining to be done on site are reduced and less exposed to the risk of accident than the majority of conventional roof construction tasks. .

As already mentioned in the general part, it should be emphasized that the design of the prefabricated roof modules according to the invention allows the transport of the modules "flat" thus reducing the risk of damage,

reducing space requirements and therefore storage and transport costs.

It is understood that the detailed description above is given by way of example which in no way has the aim of restricting the scope of the invention and that those skilled in the art will find therein information useful for reproduction. of the invention.
