Description

SYSTE M ^ _^ ^ BA iment ¾. OSSATURE BO1S

The present invention contemplates the field of the invention. building construction, wood frame. Particularly pl s., ^F in the ent is Concerns a ys em modular build for constructing a timber frame.

In this field, it is generally planned to produce a plurality of wood frame modules and assemble them to form the building. The modules generally comprise a plurality of horizontal beams and joists and a plurality of posts defining a plurality of frames that can be vertically seamed to form a lower floor and an upper floor. In addition, modules are assembled horizontally by delimiting a building mu between two modules.

For a sufficient mechanical strength both horizontally and vertically, the beams are generally made of solid wood fixed in each frame of each mod, with a means of anchorage external to the uprights which conventionally comprises at least one panel. e / or a joist or an external beam or high relian said amounts. When assembling modules, the gaps between two modules assembled horizontally are found to have a significant thickness which penalizes the internal surface of the building. Thus, the implementation of conventional modules is often blamed for a too wide thickness of the slit walls. Indeed, a conventional composition is based on uprights of 120x45 mm xempl with an outer wall facing panel, and in the center, a double wall resulting at best, for example, in thicknesses of two panels of 12 mm each, two uprights of 120 mm, associated with a 10 mm clearance and a vapor barrier of 0.1 mm, that is, a non-lined total of 274 mm wall thickness.

The terms "external" and "internal" refer to the interior of the module concerned unless otherwise stated. It is an object of the present invention to provide a modular building system wherein the thickness of the walls between two horizontally mounted modules is significantly decreased, while improving the mechanical properties of horizontal and vertical resistance of the modular system. i,

Another object of the invention consists in proposing a modular system for the design of a three-dimensional high-rigidity wooden frame construction.

To do this it is proposed a modular system of building construction timber frame comprising a plurality of wood frame modules of parallel sectionpipedicjue rectangle composed of a series of upright vertical uprights height, connected dewx by two by at least horizontal beams, at least two timber frame modules assembled ^{'horizontally,} defining a wall between lesdi modules has at least d and I of timber frame modules assembled vertically one of said uprights being provided at least u wall jamb.

Advantageously, the arrangement of the uprights and more particularly of the wall uprights makes it possible to limit the thickness of the wall according to the importance of their overlap, without affecting the mechanical properties of the wall, since the number of uprights is not sufficient. decreases. According to other aspects taken in isolation or combined according to your technical feasible combinations:

- Figure 1 is. a spatial view of a modular system according to a preferred variant d. the invention;

- F gu e 2 is a v e similar to that of Figure 1 further illustrating panels;

FIG. 3 is a sectional view of a system according to a variant similar to that of FIG. 1;

- Figure 4 is a view in the space of part of a building, wood frame; and

FIGS. 5A to 5D illustrate different wall gouging including the insertion of uprights of raised section or columns which can be found in singular points.

The present invention relates to a modular system 1 of construction. The modular system 1 according to the invention allows to build a building 2 wood frame.

The modular system 1 according to the invention comprises at least three wood frame modules 3A, 3B, 3C of rectangular paraplegeal section and each composed of at least two vertical uprights 4, connected by at least two horizontal joists 5, preferably a series of uprights 4 and connected by joists 5.

S-posts and beams are preferably further modified. The assembly forms an armature for stiffening the building 2 constructed from at least one such modular system 1. The beams may also be longitudinal members. In addition to building modules 3A, 3B, 3C, it is It is expected that at least two of them will be installed horizontally, namely in particular two modules of 3Ά and 3B construction to be erected side by side and fastened together to form the building. 2 wood frame.

The mods 3A-, 3B thus assembled delimit a wall 8 between them. The wall 8 comprises several elements of the wood frame. Among the elements of the wood frame are prev, in each module 3 &, 3B, 3 a series of uprights 4 filants any height d said module, 3S, 3C, In addition, among the uprights 4 there is at least one, of pre-erence several montan s of wall 4a which enter the constitution of the wall 8.

The uprights 4 and the posts are vertically oriented pieces of wood. The uprights 4 preferentially but not necessarily have a smaller section than the posts 6. The posts can be used at angles and / or singular points. for example apertures and ends of a module 3A, SB, 3C and the uprights 4 can be used between the ends.

The joists 5 and the beams 7 are horizontal lumber pieces. The joists 5 pre-tie but not necessarily a smaller section than the beams, For example, the joists S are about 220 section by 45 mm. Σ> e beams? can be used at the corners and end of a module 3A _f 3B and the joists S can be used between the ends. Wall reinforcements Sa may be provided in wall 1B. The wall reinforcement may be a high rail and may have a section similar to that of a rail.

According to the invention, at the same time the wall uprights are offset in a direction parallel to the corresponding wall 8 and overlap, at least pa lellemen, in a direction perpendicular to the wall 8 corresponding. In particular, at least the wall uprights 4 of a first module 3Ά, are offset with respect to the wall uprights 4a of a second adjacent module 3B. horizontally first module 3 &. In addition, these wall studs 4a overlap with each other. In addition, the Koatants de Mure 4a are at least partially covered so as to have an alignment at least partially ho iz taiemen. More particularly, when the amounts left 4s are observed along the direction of the mu 8 independently of these building elements, the nearest wall amount 4a at least masks the most distant wall stent 4a,

The horizontally adjacent modules 3A, 3B thus form, in particular, a plurality of offset frames 5 'imb icting each other at the wall 8'.

Advantageously ,. The at least one of the wall units 4a makes it possible to limit the thickness of the aur 8 according to the overlap of the amounts without affecting the mechanical properties of the wall, since the number of studs 4 is in particular not significantly decreased.

The variant system comprises at least one amount bracing means allowing said overlap. In the context of the invention, the "bracing means" is in particular a piece for maintaining a spacing between the uprights 4 or between an amount and an end or a beam. ^f lt absence of high or low smooth also allows said overlap.

Thus, the invention provides an advantageous arrangement over the prior art where bracing means external to the wall studs are provided. These means of external ntretoisement or the top and / or bottom of the wall uprights do not allow the overlapping of the wall uprights in the prior art contrary to the object of the invention,

More particula, means of spacer ent ^f used in the invention consist of the internal components of wall uprights 4a or lateral thereto and substantially internal. These elements allow to leave a space at least the rising of ar 4a or the haphazard minus wall studs 4a of the module ad acent horizontally.

The spacer means comprise preferably at least one wall reinforcement 5a which is equal to the said amount of m 4a of the corresponding module, the installation is also provided by beams 7,

According to one variant, the means for spacing the uprights 4 comprise at least one control panel 3 and / or one or more joists 5 preferably forming a frame with the uprights, delimiting each module. The panel contravenes 9 may be an OSB panel may for example measure 12 "thick.

Av nt ge ent _/ this new frame arrangement makes it possible to provide novel MDSD assembly between modules, In particular, provision may be a Mean of n solidarisa ion between on the one hand said upright wall 4a and / or said means bracing a first module 3 &, and secondly said wall post 4a and / or said bridging asoyen of a second modula 3B arranged horizontally to the first module 3A. In other words, the arrangement seating ^the invention makes it possible to provide that mo ns of a first module 3A are assembled to the amounts of a second module 3B or to the wall of the second module SB to provide connections between modules 3A, 3B, Advantageously, the chevauchasse t at least wall uprights 4a allows to provide an attachment at the overlap for example by through pieces o by gluing means. Another fastening system can be provided.

According to one variant, the modular system 1 comprises at least one insulator 10, in particular one or more insulating elements, between two horizontally adjacent modules 3A, 3B. This insulator 10 is disposed between the outside dudii. wall amount 4a of a module 3 &, and the outside of a bracing panel § of the second module 38, In particular, the insulation 10 may be a thermal insulating element and / or acoustic- Insulation can by For example, measure 40 mm thick. It can be in the form of plaque or substance; to go in the wall.

More generally, to improve the insulation, in particular acoustics, of building 2, the system comprises a spacing between a portion of said amount of spring 4a and / or said averaging of a first module 3A, and on the other hand said amount of aur 4a is / or said means of spacer of a second module 3B assembled horiaiontaleiEaent the first mod l 3 &. In particular, during the construction of the building 2, the contact between certain elements of the frames of the horizontally adjacent modules is avoided, which greatly improves the acoustic insulation. Specifically, one could predict that the wall studs 4a d- ^a first 3Â module are not in contact with the amounts of e © sau 4a. or the inner brace panel S - ¹ second module 3B,

The system further comprises at least two modules 3 & 3C wood frame ssem les vertically. The Applicant has already proposed a significant improvement in the vertical strength of a wood frame in WO 2014/140479 Ά.1. In particular, the uprights 4 of an upper module 3C rest on the uprights 4 of a lower module 3 & directly or indirectly, but without the interposition of horizontal fiberwood which is of a compressible nature,

Thus, it may be interposed between the uprights superimposed in substantially the same alignment a layer of incompreible material, such as a metal sheet, n f lm plastic material, a vapor barrier film, including fervous, etc.

The surprising advantage deriving from the invention consists in a nesting of the adjacent module wall uprights and the vertical holding by direct superposition, without the interposition of compressible material, of the amounts of superimposed modules, consists of a synergy of these characteristics of where stems greatly improved three-dimensional solidity from building 2 to According to a variant, the system comprises at least one angle water 6 or an intermediate post for each of the moduli arranged horizontally, associated with at least one beam 7 at the end of the earth. post 6,

Posts 6 of adjacent modules 3A, 3B may also be wedged and chevaachsr, at least partially, in the same manner as wall studs 4a. This con iguration can be illustrated® in Figure 5 &,

In a varian e, the o corner water 6 ^' or 1 © intermediate post is housed in an at least partial recess of said beam 7 and / or ladit other 7 es housed in an at least partial recess of said post 6. The In the same arrangement, a joist instead of a beam 7 can be envisaged. In particular, nails ê and intermediate posts, where applicable, may be provided along a joist or beam. In this case, these posts 6 e face each other by being integrated into the beam? If yes, all or part of it will be hollowed out on the location of the post 6. This configuration can be illustrated by FIG.

Alternatively, or combination, for example on other posts 6, they can be, in all xt part ,, hollowed to be arranged against the beam 7 low. This configuration can be illustrated by Figure 5C.

Alternatively, or combination, for example on other posts 6, they can be assembled in mid-wood with the joist or the beam 7 with partial recess of the post and the beam or the joist 7.

In particular, the corner posts ou or the intermediate posts, if any, can be machined in variable shapes to retain enough section, while reducing the reduction of the saur 8, the posts 6 could therefore be assembled. one along the other by form complementarity. This configuration can be illustrated by Figure S. The invention also relates to a building, wood frame comprising at least one modular system as described above,

Achieving a t¾l bd ime t 2 to com timber frame makes at least one step of constructing at least three ^modules' d * timber frame _3A; 3, 3C comprising "n series of uprights 4 running any height dud.it module. Parssi these amounts 4 are provided at least a wall amount 4.

Then we assemble horizontally at least two modul 3A and. 3B "by shifting the wall uprights 4a in a" direction parallel to mesils of the corresponding m 8, while pheasants overlaps, at least partially, in a direction perpendicular to that of the wall 8 corresponding.

In particular, the method is based on an assembly of the modules 3A, 3B horizontally by shifting the wall posts 4a relative to each other, in a direction parallel to that of the corresponding wall 8, while making them overlap, at least partially relative to each other in a direction perpendicular to that of the wall 8 corresponding.

Furthermore, the method comprises a step of constructing at least one wall S comprising said wall studs 4a.

Example

The walls of the wood frame modules obtained according to the invention are in particular in accordance with the nock D D 31.2, amounts 4a massive wood of variable section juxtaposed at regular intervals or not but often 30, 40 or 60 cm.

These amounts 4a are countervinded by a panel 9 (eg water, reconstituted long lamellae, fiber gy, agglomerated wood, etc.).

This panel 0 may be placed at the wall 8 or inside, for example a living room, indifferently, II

The implementation of the modules 3 ' _f 3B according to the inv ion with amounts 4a and panels 9 conventional results. to a composition, ho doubling can be a successive addition of:

Pc _¾ r a first module 3A:

panel of 12 sqm.

an amount 4a of 120x45 mm section (120 mm thick); Flee a eu of 10 rsm;

an acoustic insulation 10 of 40 mm thick;

Fuis for a second module 3B:

aositast 4a of 120 mm. of thickness) eco vr nt totally or partially the amount of the first module; and

~ a nne u 9 12 mm thick thick.

This results in a total of 19 mm excluding doubling, which can be reduced to 154 mm without insulation.

The wall uprights 4a can completely overlap if there is no acoustic insulation.

As a matter of course, the arrangement according to the invention makes it possible to incorporate insulators 10 or doubling plates in the openings 8 without increasing the thickness, but on the contrary in the diminu.

Other combinations are therefore possible, for example with thicker uprights classi¾ti «Bient d 145 mm or 180 m, preferably with two lining plates can be 15 mm.

M me, advantageously, the arrangement according to the invention ^enables? increase the size of the uprights 4a of the stsurs 8 without increasing the thickness, m contriser in the decreasing.

The construction method of a building according to the invention also provides for the superposition of two modules 3A to the self, 3C so that the respective uprights 4 of these modals are superior.

More precisely, each amount of the upper module 3C comes to rest 1 on u mount t; 4 of modn mod the lower 3A, this direetement, at least without interposition to compressible element, pa tic ie its interposition of a wooden element of which. the fibers would be horizontally oriented and, in fact, compressible.

Thus, between these amounts could be interposed a layer of a material incompssi e like a metal sheet and / or a. film made of synthetic material, see bitumeust, a vapor barrier, for the purpose of creating a watertight barrier, for example -
