Abstract

The beams 3 supporting a concrete slab 1 reinforced with a metal mesh 2 exhibit a series of recesses 4 in which the concrete 1 penetrates, which creates a longitudinal bond between the beams 3 and the slab 1-2 absorbing the shear forces exerted on the structure. The recesses 4 alternate on either side of each beam 3 and the relative longitudinal position of these beams is such that two neighbouring beams 3 have their recesses 4 which face each other alternating with recesses located back to back.

Description

La presente invention a pour objet un ouvrage de construction. The present invention relates to a construction work.

Le but de l'invention est de permettre de marier le bois, matériau noble, et-le béton, matériau moderne offrant de hautes performances quant à sa résistance aux efforts, notamment de compression. The object of the invention is to make it possible to combine wood, a noble material, and concrete, a modern material offering high performance as regards its resistance to stresses, in particular compression.

Or, l'alliance de ces deux matériaux, très différents, pose des problèmes, notamment en ce qui concerne la résistance aux efforts de cisaillement des ouvrages ainsi réalisés. However, the combination of these two very different materials poses problems, in particular with regard to the resistance to shearing forces of the works thus produced.

Le but de la présente invention est de fournir une solution à ce problème. The object of the present invention is to provide a solution to this problem.

Ce but est atteint grâce aux moyens définis dans la description qui va suivre. This object is achieved by the means defined in the description which follows.

Le dessin représente, à titre d'exemple, une forme d'exécution de l'objet de l'invention. The drawing represents, by way of example, an embodiment of the subject of the invention.

La fig. 1 est une vue en perspective d'un ouvrage de construction, et
La fig. 2 en est une coupe transversale, à plus grande echelle.Fig. 1 is a perspective view of a construction work, and
Fig. 2 is a cross section thereof, on a larger scale.

L'ouvrage représenté comprend une dalle l faite de beton armé d'un treillis 2, reposant sur une poutraison formée de poutres en bois 3. Ces dernières présentent, sur leurs faces latérales, des dégagements 4 alternant de part et d'autre, dans lesquels pénètre partiellement le béton 1 de la dalle. The structure shown comprises a slab l made of concrete reinforced with a trellis 2, resting on a beam formed by wooden beams 3. The latter have, on their lateral faces, clearances 4 alternating on either side, in which partially penetrates the concrete 1 of the slab.

Il résulte de cet agencement que la dalle 1-2 est solidaire, longitudinalement, des poutres 3 de la poutraison, cette liaison longitudinale absorbant les forces de cisaillement auxquelles est soumis l'ouvrage. It follows from this arrangement that the slab 1-2 is secured, longitudinally, to the beams 3 of the beams, this longitudinal connection absorbing the shear forces to which the structure is subjected.

Incidemment, il est à remarquer que la position longitudinale des poutres 3 est telle que, alternativement, deux creusures 4 de poutres voisines se font face et deux creusures sont situées dos à dos.  Incidentally, it should be noted that the longitudinal position of the beams 3 is such that, alternately, two recesses 4 of neighboring beams face each other and two recesses are located back to back.

Comme le montre en particulier la fig. 2, la section des poutres 3 est en queue d'aigle de façon à assurer une liaison entre les poutres et la dalle 1-2 dans une direction perpendiculaire au plan de celle-ci. As shown in particular in fig. 2, the section of the beams 3 is in an eagle tail so as to ensure a connection between the beams and the slab 1-2 in a direction perpendicular to the plane thereof.

Le profil des poutres 3 est en outre tel que chacune d'elles ménage deux surfaces d'appui longitudinales 5 recevant des planchettes 6 formant éléments de coffrage, qui restent apparentes une fois l'ouvrage terminé et qui absorbent le poids de dalle 1-2 avant la prise du béton 1. Une couche de matériau isolant léger 7, tel le matériau connu sur le marché sous le nom de SAGEX (Marque déposée), est interposée entre les planchettes de coffrage 6 et la dalle 1-2. Cette dernière est revêtue d'une chape de ciment 8 avec interposition d'une feuille de feutre 9. The profile of the beams 3 is further such that each of them has two longitudinal bearing surfaces 5 receiving boards 6 forming formwork elements, which remain visible after the work is completed and which absorb the weight of slab 1-2 before setting the concrete 1. A layer of light insulating material 7, such as the material known on the market under the name of SAGEX (registered trademark), is interposed between the formwork boards 6 and the slab 1-2. The latter is coated with a cement screed 8 with the interposition of a felt sheet 9.

Il est à remarquer que les dégagements 4 des poutres 3 pourraient être remplacés par des creusures de forme différente, aptes à assurer une liaison longitudinale entre les poutres et la dalle. It should be noted that the clearances 4 of the beams 3 could be replaced by recesses of different shape, capable of ensuring a longitudinal connection between the beams and the slab.

Le cas échéant les poutres 3 pourraient être en une matie- re autre que du bois.  If necessary, the beams 3 could be made of a material other than wood.
