Description
Domaine technique de l'inventionTechnical field of the invention
L'invention se rapporte à un plancher de béton comportant au moins une poutrelle présentant un axe principal, une dalle de béton qui est coulée de manière à reposer sur une face supérieure de la poutrelle, une armature métallique qui est prise dans la dalle, la poutrelle étant liée à la dalle de béton par au moins un élément de liaison rapporté qui est fixé à la poutrelle et dont au moins une partie est prise dans la dalle de béton.The invention relates to a concrete floor comprising at least one beam having a main axis, a concrete slab which is cast so as to rest on an upper face of the beam, a metal reinforcement which is taken in the slab, the beam being linked to the concrete slab by at least one added connecting element which is fixed to the beam and of which at least a part is embedded in the concrete slab.
Arrière-plan techniqueTechnical background
La réalisation de plancher en béton est déjà largement connue dans le domaine de la construction de bâtiments, notamment de bâtiments d'habitation. L'invention concerne plus particulièrement la réalisation de plancher en béton à poutrelles.The production of concrete floors is already widely known in the field of building construction, in particular residential buildings. The invention relates more particularly to the production of concrete floors with beams.
Un tel plancher à poutrelles comporte une structure porteuse en poutrelles préfabriquées en béton disposées parallèlement avec un espacement régulier, par exemple environ tous les 60 cm. On connaît des poutrelles en béton armé, en béton précontraint avec aciers filants et des poutrelles avec treillis.Such a joist floor comprises a load-bearing structure of prefabricated concrete joists arranged in parallel with regular spacing, for example approximately every 60 cm. Reinforced concrete beams, prestressed concrete with continuous steels and lattice beams are known.
Une dalle de compression en béton, appelée "hourdis", d'épaisseur comprise par exemple entre 4 cm et 10 cm, est coulée avec un élément d'armature, tel qu'un treillis soudé sur la structure porteuse. A cet effet, un coffrage est disposé entre les poutrelles. Une partie supérieure des poutrelles est directement prise dans le béton pour assurer la fixation de la dalle sur les poutrelles. Il est aussi prévu de nombreux éléments d'armature métallique pour renforcer la dalle et pour améliorer encore la fixation de la dalle sur les poutrelles. La dalle de compression assure la rigidité du plancher et permet le report des charges sur les poutrelles.A concrete compression slab, called a "slab", with a thickness of between 4 cm and 10 cm, for example, is cast with a reinforcement element, such as a mesh welded onto the load-bearing structure. For this purpose, a formwork is placed between the beams. An upper part of the beams is set directly in the concrete to secure the slab to the beams. Many metal reinforcement elements are also provided to reinforce the slab and to further improve the fixing of the slab to the beams. The compression slab ensures the rigidity of the floor and allows the transfer of loads to the beams.
L'espacement prévu entre deux poutrelles adjacentes est souvent comblé par des entrevous, parfois appelés aussi « hourdis » par abus de langage. Les entrevous peuvent servir de coffrage à la dalle de compression qui les recouvre. Selon la forme et le matériau utilisés, les entrevous ont un rôle porteur ou non. Ils permettent aussi de renforcer les performances d’un plancher, par exemple l'isolation thermique ou phonique.The spacing provided between two adjacent beams is often filled by interjoists, sometimes also called "slabs" by abuse of language. The interjoists can be used as formwork for the compression slab which covers them. Depending on the shape and material used, the interjoists have a supporting role or not. They also make it possible to reinforce the performance of a floor, for example thermal or sound insulation.
Un tel plancher à poutrelles présente cependant l'inconvénient d'utiliser de nombreuses matières premières non renouvelables, notamment l'acier utilisé pour les armatures. En outre, la production de poutrelles en béton consomme énormément d'énergie.Such a floor with beams, however, has the disadvantage of using many non-renewable raw materials, in particular the steel used for the reinforcements. In addition, the production of concrete beams consumes a lot of energy.
L'invention vise à obtenir un plancher en béton à poutrelles présentant des propriétés mécaniques préservées tout en réduisant l'utilisation de matières premières non renouvelable, notamment d'acier, et en réduisant son empreinte carbone.The invention aims to obtain a concrete floor with beams having preserved mechanical properties while reducing the use of non-renewable raw materials, in particular steel, and reducing its carbon footprint.
L'invention propose un plancher de béton comportant au moins une poutrelle présentant un axe principal, une dalle de béton qui est coulée de manière à reposer sur une face supérieure de la poutrelle, une armature métallique qui est prise dans la dalle, la poutrelle étant liée à la dalle de béton par au moins un élément de liaison rapporté qui est fixé à la poutrelle et dont au moins une partie est prise dans la dalle de béton, caractérisé en ce que la poutrelle et l'élément de liaison sont réalisés en bois.The invention proposes a concrete floor comprising at least one beam having a main axis, a concrete slab which is cast so as to rest on an upper face of the beam, a metal reinforcement which is taken in the slab, the beam being linked to the concrete slab by at least one added connecting element which is fixed to the beam and of which at least a part is taken in the concrete slab, characterized in that the beam and the connecting element are made of wood .
Un tel plancher permet de limiter le recours au béton et aux éléments métalliques. La réalisation d'éléments en bois requiert en effet beaucoup moins d'énergie que la réalisation d'éléments équivalents en métal et en béton.Such a floor makes it possible to limit the use of concrete and metal elements. The realization of wooden elements indeed requires much less energy than the realization of equivalent elements in metal and concrete.
Selon un autre aspect du plancher réalisé selon les enseignements de l'invention, l'élément de liaison est formé d'une lame de bois qui s'étend selon un axe principal longitudinal et qui présente une face inférieure de fixation avec la poutrelle et une face supérieure de contact avec la dalle de béton, la lame de bois comportant des creux produits par enlèvement de matière dans sa face supérieure dans lesquels le béton de la dalle est coulé, les parois globalement transversales délimitant les creux étant aptes à transmettre les efforts de cisaillement exercés globalement longitudinalement par la dalle sur la lame de bois lors d'une flexion du plancher.According to another aspect of the floor produced according to the teachings of the invention, the connecting element is formed of a strip of wood which extends along a main longitudinal axis and which has an underside for attachment to the beam and a upper face of contact with the concrete slab, the wooden strip comprising hollows produced by removal of material in its upper face into which the concrete of the slab is poured, the generally transverse walls delimiting the hollows being able to transmit the forces of shear exerted overall longitudinally by the slab on the strip of wood during bending of the floor.
Cette caractéristique permet notamment de garantir que la dalle de béton demeure fixée aux poutrelles même en cas de flexion de grande amplitude du plancher. Elle permet plus particulièrement d'éviter le glissement de la dalle de béton par rapport aux poutrelles.This characteristic makes it possible in particular to guarantee that the concrete slab remains fixed to the beams even in the event of large amplitude bending of the floor. More specifically, it prevents the concrete slab from slipping relative to the beams.
Selon un autre aspect du plancher réalisé selon les enseignements de l'invention, les creux sont formés par des rainures qui s'étendent globalement transversalement.According to another aspect of the floor produced according to the teachings of the invention, the recesses are formed by grooves which extend generally transversely.
De tel creux sont aisés, rapides et peu onéreux à réaliser sur des lames de bois.Such hollows are easy, quick and inexpensive to make on wooden slats.
Selon un autre aspect du plancher réalisé selon les enseignements de l'invention, la lame de bois est délimitée par au moins deux chants qui sont munis de moyens pour résister à l'arrachement vertical de la dalle par rapport à la lame de bois.According to another aspect of the floor produced according to the teachings of the invention, the strip of wood is delimited by at least two edges which are provided with means to resist the vertical tearing of the slab relative to the strip of wood.
Il est en effet important de garantir que la dalle ne puisse être arrachée verticalement par rapport aux poutrelles.It is indeed important to guarantee that the slab cannot be torn vertically in relation to the beams.
Selon un autre aspect du plancher réalisé selon les enseignements de l'invention, les moyens pour résister à l'arrachement sont formés par des stries qui s'étendent longitudinalement et dans lesquelles le béton de la dalle est coulé.According to another aspect of the floor produced according to the teachings of the invention, the means for resisting tearing are formed by ridges which extend longitudinally and in which the concrete of the slab is poured.
Comme pour les rainures, de telles stries sont aisées, rapides et peu onéreuses à réaliser sur des lames de bois.As for the grooves, such streaks are easy, quick and inexpensive to make on wooden slats.
Selon un autre aspect du plancher réalisé selon les enseignements de l'invention, les moyens pour résister à l'arrachement sont formés par une forme biseautée des chants.According to another aspect of the floor produced according to the teachings of the invention, the means for resisting tearing are formed by a beveled shape of the edges.
Il s'agit d'une variante de réalisation des moyens pour résister à l'arrachement qui sont tout aussi aisés, rapides et peu onéreux à réaliser sur des lames de bois.This is an alternative embodiment of the means for resisting tearing which are just as easy, quick and inexpensive to produce on wooden slats.
Selon un autre aspect du plancher réalisé selon les enseignements de l'invention, la poutrelle est réalisée en un bois tendre, tandis que la lame de bois est réalisée en un bois dur.According to another aspect of the floor made according to the teachings of the invention, the beam is made of a soft wood, while the wooden strip is made of a hard wood.
Ceci permet de garantir une bonne élasticité et une bonne résistance à la rupture pour la poutrelle, tandis que les lames de bois présentent une dureté à même de garantir leur fonction de fixation de la dalle de béton.This makes it possible to guarantee good elasticity and good breaking strength for the beam, while the wooden strips have a hardness capable of guaranteeing their function of fixing the concrete slab.
Selon un autre aspect du plancher réalisé selon les enseignements de l'invention, la lame de bois est fixée par collage de sa face inférieure de fixation sur la face supérieure de la poutrelle.According to another aspect of the floor made according to the teachings of the invention, the wooden strip is fixed by gluing its lower fixing face to the upper face of the beam.
Selon un autre aspect du plancher réalisé selon les enseignements de l'invention, la face inférieure de fixation de la lame de bois comporte des fentes longitudinales de décharge qui permettent d'absorber les variations dimensionnelles de la poutrelle en fonction des conditions hygrométriques.According to another aspect of the floor produced according to the teachings of the invention, the lower face for fixing the wooden strip comprises longitudinal discharge slots which make it possible to absorb the dimensional variations of the beam according to the hygrometric conditions.
Selon un autre aspect du plancher réalisé selon les enseignements de l'invention, la lame de bois est fixée à la poutrelle par vissage ou par clouage.According to another aspect of the floor produced according to the teachings of the invention, the wooden strip is fixed to the beam by screwing or by nailing.
Selon un autre aspect du plancher réalisé selon les enseignements de l'invention, il comporte au moins une lame de bois dont l'axe principal longitudinal s'étend parallèlement à l'axe principal des poutrelles, dite longeron.According to another aspect of the floor produced according to the teachings of the invention, it comprises at least one strip of wood whose main longitudinal axis extends parallel to the main axis of the beams, called a spar.
Selon un autre aspect du plancher réalisé selon les enseignements de l'invention, au moins une poutrelle comporte un longeron qui s'étend sensiblement sur toute la longueur de la face supérieure du tronçon de la poutrelle destiné à recevoir la dalle de béton.According to another aspect of the floor produced according to the teachings of the invention, at least one beam comprises a spar which extends substantially over the entire length of the upper face of the section of the beam intended to receive the concrete slab.
Selon un autre aspect du plancher réalisé selon les enseignements de l'invention, au moins une poutrelle comporte plusieurs longerons qui sont répartis de manière alignée sur toute la longueur de la face supérieure de la poutrelle destinée à recevoir la dalle de béton.According to another aspect of the floor produced according to the teachings of the invention, at least one beam comprises several beams which are distributed in an aligned manner over the entire length of the upper face of the beam intended to receive the concrete slab.
Selon un autre aspect du plancher réalisé selon les enseignements de l'invention, il comporte :According to another aspect of the floor produced according to the teachings of the invention, it comprises:
- au moins deux poutrelles chacune équipée de plusieurs longerons espacés longitudinalement d'un intervalle,- at least two beams each equipped with several longerons spaced longitudinally by an interval,
- au moins une lame de bois dont l'axe principal longitudinal s'étend selon une direction orthogonale à l'axe principal des poutrelles, dite traverse, et fixée sur la face de chacune des poutrelles dans l'intervalle entre deux longerons.- At least one strip of wood whose main longitudinal axis extends in a direction orthogonal to the main axis of the beams, called crosspiece, and fixed to the face of each of the beams in the interval between two beams.
Cette caractéristique permet de réaliser une partie de la fonction de support de la dalle au moyen de lames de bois. Cela permet notamment de réduire les dimensions de l'armature métallique, et donc la quantité de métal présent dans le plancher.This characteristic makes it possible to carry out part of the support function of the slab by means of wooden strips. This makes it possible in particular to reduce the dimensions of the metal reinforcement, and therefore the quantity of metal present in the floor.
Selon un autre aspect du plancher réalisé selon les enseignements de l'invention, les lames de bois sont traitées avec un produit hydrofuge.According to another aspect of the floor produced according to the teachings of the invention, the wooden strips are treated with a water-repellent product.
Cette caractéristique permet d'éviter que l'eau présente dans le béton lors du coulage de la dalle ne soit absorbée par les lames de bois. Ainsi, les lames de bois sont protégées contre le pourrissement, tandis que le béton conserve ses caractéristiques mécaniques, y compris au niveau de l'interface avec les lames de bois pendant la prise.This feature prevents the water present in the concrete during the pouring of the slab from being absorbed by the wooden strips. Thus, the wooden slats are protected against rotting, while the concrete retains its mechanical characteristics, including at the interface with the wooden slats during setting.
L'invention concerne aussi un procédé de réalisation d'un plancher selon les enseignements de l'invention, caractérisé en ce qu'il consiste à :The invention also relates to a method for producing a floor according to the teachings of the invention, characterized in that it consists of:
- fixer sur la face supérieure de chaque poutrelle au moins une lame de bois ;- fix on the upper face of each beam at least one strip of wood;
- agencer un coffrage et/ou des entrevous dont une face supérieure affleure la face supérieure des poutrelles de manière que les lames de bois fassent saillie par rapport au coffrage et/ou aux entrevous ;- arranging a formwork and/or interjoists whose upper face is flush with the upper face of the beams so that the wooden slats protrude from the formwork and/or the interjoists;
- agencer une armature métallique sur les poutrelles ;- arrange a metal reinforcement on the beams;
- couler une dalle de béton qui prenne l'armature métallique et les lames de bois.- pour a concrete slab that takes the metal frame and the wooden slats.
