Description

La présente invention a pour objet un système de construction ossature bois industrialisé pour la réalisation de bâtiments.The present invention relates to an industrialized timber frame construction system for the construction of buildings.

La présente invention a plus particulièrement pour objet un système de construction dont les performances permettent des empilements sur de nombreux niveaux d'étages sans structure porteuse rapportée.The subject of the present invention is more particularly a building system whose performance allows stacking on many storey levels without an added supporting structure.

On connaît déjà des systèmes construction en bois, ils sont essentiellement au nombre de trois, et présentent chacun des avantages et des inconvénients.Wood construction systems are already known, they are essentially three in number, and each has advantages and disadvantages.

On connaît ainsi l'assemblage de murs en bois massif contre-collé, où des panneaux de bois continus sont reconstitués à partir d'assemblages de bois de petites sections en couches croisées. Les panneaux ainsi obtenus sont utilisés en remplissage de structure porteuse ou en tant que structure porteuse suivant des normes d'assemblages propres.The assembly of laminated solid wood walls is thus known, where continuous wood panels are reconstituted from wood assemblies of small sections in crossed layers. The panels thus obtained are used in filling of the load-bearing structure or as load-bearing structure according to specific assembly standards.

On connaît également les structures poteaux-poutres, comprenant une structure de bois de grande section qui est assemblée en étages, son dimensionnement pour les éléments verticaux (poteaux) et horizontaux (poutres) ainsi que leurs liaisons en assemblages reprend l'ensemble des efforts nécessaires à la réalisation du bâtiment, les dalles rapportées ainsi que les panneaux de mur viennent achever l'enveloppe du bâtiment et peuvent éventuellement assurer des fonctions de contreventement de la structure poteaux-poutres porteuse.Post-beam structures are also known, comprising a large section wooden structure which is assembled in floors, its dimensioning for the vertical (posts) and horizontal (beams) elements as well as their connections in assemblies takes up all the necessary efforts. when building the building, the added slabs as well as the wall panels complete the building envelope and can possibly provide bracing functions for the load-bearing post-beam structure.

Enfin, on connaît également les constructions de type ossature bois, à savoir qu'un panneau de mur est constitué de montants bois verticaux pris sur une lisse basse et une lisse haute pour la constitution d'un panneau. Le panneau est constitué de cette structure contreventée par un panneau de contreventement, ou deux, fixé sur la structure. Les panneaux ainsi obtenus sont utilisés en remplissage de structure porteuse ou en tant que structure porteuse suivant des normes d'assemblages propres.Finally, constructions of the wood frame type are also known, namely that a wall panel consists of vertical wooden uprights taken from a bottom rail and a top rail to form a panel. The panel is made up of this structure braced by a bracing panel, or two, fixed to the structure. The panels thus obtained are used in filling of the load-bearing structure or as a load-bearing structure according to own assembly standards.

Ces murs ossature bois peuvent être posés sur les planchers intermédiaires ou sur des structures poteaux-poutres.These timber frame walls can be placed on intermediate floors or on post-beam structures.

Les lisses basse et haute du panneau ont plusieurs fonctions mécaniques et structurelles, à savoir :

  • fixation et maintien des montants à l'entraxe voulu les uns par rapport aux autres
  • fixation de la lisse basse pour le maintien en alignement et en descente de charges du panneau.
  • fixation des éléments de construction supérieurs sur la lisse haute du panneau.
The bottom and top rails of the panel have several mechanical and structural functions, namely:
  • fixing and maintaining the uprights at the desired spacing with respect to each other
  • attachment of the bottom rail to keep the panel loads aligned and lowered.
  • fastening of the upper construction elements to the top rail of the panel.

Les lisses basses et hautes permettent de couturer le matériau ou système de contreventement en bordures basse et haute du panneau. Un système de construction modulaire similaire est connu de WO2006/096899A , qui décrit une structure de bâtiment en bois sans interposition de bois aux fibres horizontales en reprise de charge.The bottom and top rails allow the material or bracing system to be sewn into the bottom and top edges of the panel. A similar modular building system is known from WO2006/096899A , which describes a wooden building structure without the interposition of wood with horizontal fibers in load bearing.

La construction ossature bois conventionnelle, présente toutefois des limites. Ainsi, les lisses basses et hautes d'un panneau ossature bois reprennent la charge portée par chaque montant dans le sens perpendiculaire à la fibre du bois.Conventional timber frame construction, however, has its limits. Thus, the bottom and top rails of a wood frame panel take up the load carried by each upright in the direction perpendicular to the grain of the wood.

Le bois porte beaucoup plus de charge par unité de surface dans le sens de sa fibre que dans le sens perpendiculaire à sa fibre, il en résulte un écrasement des lisses ou éléments de bois massifs aux fibres horizontales aux descentes ponctuelles de charge.Wood carries much more load per unit area in the direction of its fiber than in the direction perpendicular to its fiber, resulting in a crushing of the smooth or solid wood elements with horizontal fibers at point load drops.

Typiquement, un système ossature conventionnel avec transfert de charges sur des bois aux fibres horizontales permet de porter des bâtiments en ossature bois jusqu'en niveau +2, c'est-à-dire trois niveaux, au-delà il y a risque d'écrasement ponctuel de ces bois massifs qui arrivent en limite structurelle.Typically, a conventional frame system with transfer of loads on wood with horizontal fibers makes it possible to carry wood frame buildings up to level +2, that is to say three levels, beyond which there is a risk of punctual crushing of these solid woods which arrive at the structural limit.

La présente invention a pour but de proposer un système de construction préfabriqué de structure ossature bois qui soit transportable et qui soit très largement empilable sans structure porteuse rapportée et sans être limité en nombre de niveaux réalisables.The object of the present invention is to provide a prefabricated construction system with a wooden frame structure which is transportable and which is very widely stackable without any added supporting structure and without being limited in the number of achievable levels.

Ainsi, l'invention concerne un système de construction modulaire selon la revendication 1.Thus, the invention relates to a modular construction system according to claim 1.

La descente de charge autorisée par montant est bien supérieure dans cette configuration, il n'y a pas de bois aux fibres horizontales en reprise de charge et donc pas d'écrasement .The lowering of the load authorized per upright is much higher in this configuration, there is no wood with horizontal fibers in load recovery and therefore no crushing.

Il n'y a pas de poteaux de reprise nécessaires comme dans un système poteau-poutre, on reste dans de l'ossature bois standard, sections de montants et entraxe, classe structurelle de bois selon la législation en vigueur.There are no support posts necessary as in a post-beam system, we remain in the standard wooden frame, upright sections and spacing, structural class of wood according to the legislation in force.

L'invention concerne encore un système de construction modulaire selon la revendication 2.The invention further relates to a modular construction system according to claim 2.

Les éléments intercalés, réalisés dans un matériau, ou dans un composite de plusieurs matériaux, du métal par exemple, sont susceptibles de constituer également des moyens de fixationThe interposed elements, made of one material, or of a composite of several materials, metal for example, are also capable of constituting fastening means.

Leur nature et leurs caractéristiques dimensionnelles, sont bien entendu choisis et calculées en fonction des caractéristiques du bâtiment, et notamment de la charge à laquelle ils peuvent être soumis. Cela exclut les bois massifs qui, comme cela a été évoqué précédemment, peuvent arriver en limite structurelle de compression, et ainsi présenter des risques d'écrasement ponctuel.Their nature and their dimensional characteristics are of course chosen and calculated according to the characteristics of the building, and in particular the load to which they may be subjected. This excludes solid woods which, as mentioned above, can reach the structural limit of compression, and thus present risks of occasional crushing.

Ces éléments peuvent consister en des tôles, ou des profilés non limitativement en métal, des cornières par exemple. Ils peuvent également être réalisés dans des matériaux tels que du béton, armé ou non, une résine renforcée ou non de fibres, des panneaux de bois reconstitué, des bois industriels aboutées et ou contrecollés, des bois industriels laminés, des essences de bois sélectionnées pour offrir les propriétés de compression exigées, des matériaux polymères ou biosourcés à base de liants polymères ou naturels, des métaux ferreux ou non ferreux, des assemblages de plusieurs de ces matériaux, l'un pouvant offrir une résistance à la compression ou au cisaillement à titre d'exemple, l'autre offrant une résistance à un moment, ou bien un des composites peut être sélectionné pour offrir une résistance au feu par exemple.These elements can consist of sheets, or non-limitatively metal sections, angles for example. They can also be made of materials such as concrete, reinforced or not, resin reinforced or not with fibers, reconstituted wood panels, finger-jointed and or laminated industrial wood, laminated industrial wood, wood species selected for offer the required compression properties, polymeric or biosourced materials based on polymeric or natural binders, ferrous or non-ferrous metals, assemblies of several of these materials, one of which can offer resistance to compression or shear as example, the other offering resistance at a time, or one of the composites can be selected to offer fire resistance for example.

II est possible qu'un montant vertical ne soit pas dans le prolongement exact du montant vertical correspondant du niveau supérieur et/ou inférieur. Ces éléments ont pour but de permettre le rattrapage d'un décalage dans le sens longitudinal du mur.It is possible that a vertical upright is not in the exact extension of the corresponding vertical upright of the upper and/or lower level. The purpose of these elements is to make up for an offset in the longitudinal direction of the wall.

Selon l'invention, les montants verticaux sont assemblés sur un longeron horizontal bas qui est destiné à porter des solives de plancher.According to the invention, the vertical uprights are assembled on a low horizontal spar which is intended to carry floor joists.

Selon l'invention, les montants verticaux sont assemblés sur un longeron horizontal haut qui est destiné à porter des solives de plafond ou de toiture.According to the invention, the vertical uprights are assembled on a high horizontal spar which is intended to carry ceiling or roof joists.

Les unités préfabriquées sont destinées à être superposées entre elles, et des ensembles d'unités superposées peuvent être juxtaposés, ce qui peut être réalisé selon des manières nombreuses et variées, comme par exemple, non limitativement, entre longerons, entre longerons et solives, entre longerons et montants, entre montants et montants, entre montants et solives, etc....The prefabricated units are intended to be superimposed on each other, and sets of superimposed units can be juxtaposed, which can be achieved in many and varied ways, such as for example, without limitation, between stringers, between stringers and joists, between stringers and uprights, between uprights and uprights, between uprights and joists, etc....

Les avantages et les caractéristiques du système de construction selon l'invention, ressortiront plus clairement de la description qui suit et qui se rapporte au dessin annexé, lequel en représente plusieurs modes de réalisation non limitatifs.The advantages and characteristics of the construction system according to the invention will emerge more clearly from the description which follows and which relates to the appended drawing, which shows several non-limiting embodiments thereof.

En référence à la figure 1, on peut voir une structure réalisée selon le système de construction selon l'invention. Cette structure comprend deux modules 1 superposés, qui sont de conceptions identiques.With reference to the figure 1 , we can see a structure made according to the construction system according to the invention. This structure comprises two superimposed modules 1, which are of identical designs.

Chaque module 1 comprend des montants verticaux 2, parallèles et espacés suivant un entraxe déterminé pour la constitution d'un mur porteur, entraxe qui peut être assuré, non limitativement par des entretoises, non représentées.Each module 1 comprises vertical uprights 2, parallel and spaced along a determined center distance for the constitution of a load-bearing wall, center distance which can be ensured, without limitation by spacers, not shown.

Dans le mode de réalisation représenté, les montants 2 d'un même mur d'un module 1 sont assemblés en partie basse par un longeron horizontal 3, et les deux longerons horizontaux 3 de deux murs en regard portent des solives de plancher 4, et tandis que les montants 2 des deux murs portent en partie haute des solives de plafond ou de toiture 5.In the embodiment shown, the uprights 2 of the same wall of a module 1 are assembled at the bottom by a horizontal spar 3, and the two horizontal spars 3 of two facing walls carry floor joists 4, and while the uprights 2 of the two walls carry ceiling or roof joists 5 in the upper part.

Par ailleurs, chacun des murs est renforcé par contreventement intérieur 20 et/ou extérieur 21.Furthermore, each of the walls is reinforced by internal 20 and/or external 21 bracing.

Ces assemblages peuvent être de toute nature, ils seront calculés pour être suffisants pour garantir la cohésion de la structure de l'unité modulaire au transport et ensuite dans son usage en tant qu'élément structurel du bâtiment.These assemblies can be of any kind, they will be calculated to be sufficient to guarantee the cohesion of the structure of the modular unit during transport and then in its use as a structural element of the building.

Selon l'invention, le module 1 supérieur repose sur le module 1 inférieur par aboutement direct de chacun des montants verticaux 2 du module 1 supérieur avec un montant vertical 2 du module 1 inférieur. Les montants verticaux 2 sont donc, d'un niveau à un autre, dans le prolongement l'un de l'autre, sans interposition de bois aux fibres horizontales en reprise de charge et donc pas de risque d'écrasement.According to the invention, the upper module 1 rests on the lower module 1 by direct abutment of each of the vertical uprights 2 of the upper module 1 with a vertical upright 2 of the lower module 1. The vertical uprights 2 are therefore, from one level to another, in the extension of one another, without interposition of wood with horizontal fibers in load bearing and therefore no risk of crushing.

En référence maintenant à la figure 2, on peut voir une variante, où les montants verticaux 2 d'un même mur sont assemblés en partie haute sur un longeron horizontal 50, lequel porte les solives de plafond ou de toiture 5.Referring now to the figure 2 , we can see a variant, where the vertical uprights 2 of the same wall are assembled in the upper part on a horizontal beam 50, which carries the ceiling or roof joists 5.

En référence maintenant à la figure 3, on peut voir un autre mode de réalisation d'une structure Ainsi, chacun des montants verticaux 1 d'un module 1 supérieur ne sont pas aboutés directement à un montant vertical 1 du module 1 inférieur, mais est intercalé un élément 6 réalisé en un matériau, ou dans un composite de plusieurs matériaux, qui est choisi en sorte d'être apte à conserver ses propriétés mécaniques sous la contrainte de la charge du ou des étages supérieurs, et qui peut consister, non limitativement, en une tôle.Referring now to the picture 3 , one can see another embodiment of a structure Thus, each of the vertical uprights 1 of an upper module 1 are not butted directly to a vertical upright 1 of the lower module 1, but an element 6 made of a material, or in a composite of several materials, which is chosen so as to be capable of retaining its mechanical properties under the stress of the load of the upper stage(s), and which may consist, without limitation, of a sheet.

Selon les propriétés mécaniques des éléments 6, il peut être envisagé de décaler les montants verticaux 2 d'un module 1 inférieur par rapport à ceux d'un module 1 supérieur, les éléments 6 assurant le report de charge, et étant choisis en sorte de résister aux contraintes de compression et de cisaillement générées par le bâtiment .Depending on the mechanical properties of the elements 6, it may be envisaged to offset the vertical uprights 2 of a lower module 1 with respect to those of an upper module 1, the elements 6 ensuring the load transfer, and being chosen so as to resist the compressive and shear stresses generated by the building.

Dans ce mode de réalisation on notera que les deux modules 1 superposés partagent deux longerons horizontaux 30 et les mêmes solives 40, qui pour le module 1 inférieur constituent des longerons hauts et respectivement des solives de plafond, tandis que pour le module supérieur ils constituent des longerons bas et respectivement des solives de plancher.In this embodiment, it will be noted that the two superimposed modules 1 share two horizontal beams 30 and the same joists 40, which for the lower module 1 constitute high beams and ceiling joists respectively, while for the upper module they constitute bottom stringers and floor joists respectively.

La figure 4, qui concerne le même mode de réalisation permet de constater que d'une part que les éléments 6 intercalés entre les montants verticaux 2 d'un module 1 inférieur et ceux d'un module 1 supérieur consistent, non limitativement, en des profilés en forme de cornière, et d'autre part que les assemblages des différents composants de la structure sont réalisés au travers de connecteurs C.There figure 4 , which relates to the same embodiment, shows that on the one hand the elements 6 interposed between the vertical uprights 2 of a lower module 1 and those of an upper module 1 consist, without limitation, of shaped sections of angle, and on the other hand that the assemblies of the various components of the structure are carried out through connectors C.

Quel que soit le mode de réalisation considéré, le système de construction selon l'invention permet de réaliser des structures sans limitation en nombre de niveaux.Whatever the embodiment considered, the construction system according to the invention makes it possible to produce structures without limitation in the number of levels.
