Description
La présente invention a pour objet une dalle mixte bois béton comportant une partie inférieure en bois et une partie supérieure en béton.The present invention relates to a composite concrete slab having a lower part of wood and a concrete upper part.

La dalle selon la présente invention présente notamment l'avantage d'un système de fabrication simple et modulaire, ne nécessitant qu'un nombre restreint de pièces standards pouvant être préfabriquées en usine et qui sont facilement transportables.The slab according to the present invention has the particular advantage of a simple and modular manufacturing system, requiring only a limited number of standard parts that can be prefabricated in the factory and are easily transportable.

Dans le cadre de la présente demande, on appelle bastaing une pièce de bois de section rectangulaire. De préférence, ce bastaing aura une longueur comprise entre 2 et 5 m, avec une section ayant un rapport largeur/hauteur compris entre 0.3 et 0.5. Ce bastaing, après usinage, est l'élément constitutif principal de la partie inférieure de la dalle. Dans la description qui suit, ce bastaing a une longueur de 3 m et une section extérieure de 40 mm x 100 mm.In the context of the present application, bastaing is a piece of wood of rectangular section. Preferably, this bastaing will have a length of between 2 and 5 m, with a section having a width / height ratio of between 0.3 and 0.5. This bastaing, after machining, is the main constituent of the lower part of the slab. In the following description, this bastaing has a length of 3 m and an outer section of 40 mm x 100 mm.
La partie inférieure en bois de la dalle selon l'invention comprend une succession de tels bastaings usinés, disposés alternativement verticalement (ci-après bastaing vertical) et horizontalement (ci-après bastaing horizontal).The lower wooden part of the slab according to the invention comprises a succession of such machined bastaings, arranged alternately vertically (hereinafter vertical bastaing) and horizontally (hereinafter horizontal bastaing).
Un exemple de dalle selon l'invention est représenté à la
Tel que représenté à la
Tel que représenté à la
On a représenté sur les
Un détail d'une coupe en travers d'une dalle représenté à la
Les bastaings verticaux 1 et horizontaux 2 décrits ci-dessus peuvent avantageusement être réalisés par usinage d'un bastaing brut standard de 3 m de long et de 40 x 100 mm de section. Cet usinage est réalisé par un passage longitudinal du bastaing brut dans une moulurière quatre faces qui fraise le bastaing brut sur toute sa longueur pour lui donner le contour définitif de sa section de base, à savoir fraisage longitudinal 12 et rainures longitudinales 13 et 14 pour les bastaings verticaux 1 et rainures longitudinales 24 et 25 pour les bastaings horizontaux 2. Les redents 16 et 28 sont ensuite formés par fraisage transversal des creusures 15 et 27 à l'aide d'un outillage adéquat, de préférence agencé pour permettre un passage transversal continu du bastaing sans relèvement de l'outil de coupe. Bien entendu, tout autre procédé d'usinage permettant d'obtenir le même résultat peut être envisagé. Afin de simplifier les opérations d'usinage et de manutention, comme on l'a décrit plus haut, la formation des redents 16 et 28 par fraisage des creusures 15 et 27 n'est effectuée que sur une seule face des bastaings, qu'il s'agisse des bastaings verticaux ou horizontaux. Mais bien entendu, selon une variante d'exécution, non représentée sur les dessins, des redents pourraient également être formés sur l'autre face verticale des bastaings verticaux. Une fois usinés, les bastaings verticaux et les bastaings horizontaux sont disposés sur des palettes et emballés pour être transportés sur le chantier.The
Le recours à des bastaings de longueur limitée, par exemple 3 mètres comme décrit ci-dessus, n'empêche pas la construction de dalle de portées supérieures, par exemple de dalles de 10 mètres de portée. Il suffit à cet effet, comme illustré à la
En résumé, les redents assurent le non-glissement du béton sur le bois (résistance au cisaillement), mais ils assurent aussi, grâce à l'action de blocage du béton, le passage de l'effort de traction d'un bastaing à son voisin. Pour des dalles ayant une portée égale à celle d'un bastaing, la résistance en traction d'une paire de bastaings adjacents est celle de deux bastaings. Dans le cas d'une dalle ayant une portée supérieure à celle d'un bastaing, la résistance en traction d'une paire de bastaings adjacents est celle d'un bastaing.In summary, the redents ensure the non-slip of the concrete on the wood (shear strength), but they also ensure, thanks to the blocking action of the concrete, the passage of the tensile force of a bastaing to its neighbour. For slabs having a range equal to that of a bastaing, the tensile strength of a pair of adjacent bastaings is that of two bastaings. In the case of a slab having a range greater than that of a bastaing, the tensile strength of a pair of adjacent bastaings is that of a bastaing.
Le fait d'utiliser des bastaings de longueur unique, en l'occurrence 3 m dans l'exemple décrit ici, permet un meilleur conditionnement pour le transport. Sur une palette de 80 cm de largeur on place un paquet de deux cents bastaings, soit cent bastaings verticaux et cent bastaings horizontaux, pour un poids total de 940 kg. Ces deux cents bastaings permettent la construction de 40,8 m2 de coffrage.Using single-length bastaings, in this case 3 m in the example described here, allows better packaging for transport. On a pallet 80 cm wide a pack of two hundred bastaings is placed, one hundred vertical and one hundred horizontal bastaings, for a total weight of 940 kg. These two hundred bastaings allow the construction of 40,8 m 2 of formwork.
Bien que par nature, une dalle bois mixte béton ne porte en principe que dans une seule direction, une armature d'acier complémentaire peut toutefois dans une certaine mesure pallier cet inconvénient.Although, by nature, a composite concrete slab is normally only in one direction, a complementary steel reinforcement can however, to a certain extent, overcome this disadvantage.
Dans le cas de la réalisation d'une dalle mixte bois béton ayant une portée supérieure à la longueur d'un bastaing, par exemple pour une dalle de l'ordre de 7 m de portée, telle que celle représentés schématiquement à la
- 1. Mise en place de filières d'étayage, à 1,50 m d'écartement.
- 2. Mise en place depuis un bord d'une première ligne de bastaings verticaux. Le premier bastaing de cette ligne est entier, d'une longueur Lv. de 3 m. A l'autre extrémité, le dernier bastaing est raccourci (1/3 de Lv) pour s'adapter à la dimension de l'ouvrage. La chute est réutilisable.
- 3. Mise en place de la deuxième ligne de bastaings horizontaux Le premier bastaing a une longueur LH de 1,5 m seulement, de telle sorte que les joints de la première ligne soient toujours bordés par un bastaing continu de 3 m. Cette disposition en quinconce des bastaings assure la continuité de l'effort de traction qui "serpente" en quelque sorte d'un bastaing à son voisin.
- 4. Poursuite de la pose des bastaings selon ce schéma.
- 5. Construction des coffrages de bords.
- 6. Construction des coffrages de réservation. Découpe du coffrage.
- 7. Pose des conduites noyées.
- 8. Pose éventuelle d'une armature complémentaire.
- 9. Bétonnage au béton ordinaire.
- 10.Après quelques jours, démontage de deux sur trois filières d'étayage.
- 11. après quelques semaines, démontage complet de l'étayage.
- 1. Installation of bracing dies, 1.50 m apart.
- 2. Set up from an edge of a first line of vertical bastaings. The first bastaing of this line is whole, of length L v . of 3 m. At the other end, the last bastaing is shortened (1/3 of L v ) to fit the size of the structure. The fall is reusable.
- 3. Installation of the second line of horizontal bastaings The first bastaing has a length L H of only 1.5 m, so that the joints of the first line are always bordered by a continuous bastaing of 3 m. This staggered arrangement of bastaings ensures the continuity of the traction force that "winds" in a way of a bastaing to his neighbor.
- 4. Continuation of bastaings according to this scheme.
- 5. Construction of edge forms.
- 6. Construction of reservation forms. Cutting of the formwork.
- 7. Installation of flooded pipes.
- 8. Possible installation of a complementary reinforcement.
- 9. Concreting with ordinary concrete.
- 10.After a few days, disassembly of two of three shoring dies.
- 11. after a few weeks, complete dismantling of the shoring.

On donne ci-après une exemple de calcul d'une dalle mixte bois béton. Cet exemple porte sur un plancher de maison d'habitation. Le calcul est basé sur les normes de la SIA (Société suisse des ingénieurs et des architectes).An example of calculation of a mixed concrete slab is given below. This example deals with a dwelling house floor. The calculation is based on the standards of the SIA (Swiss Society of Engineers and Architects).
Les caractéristiques géométriques sont les suivantes :
Les actions qui sollicitent ce plancher sont exclusivement verticales, dirigées de haut vers le bas :
La qualité du bois est C35, dont les valeurs de dimensionnement sont :
La section résistante déterminante du bois:
La résistance en flexion du bois - armature négligéeBending strength of wood - neglected reinforcement
La traction est reprise exclusivement par le bois, s'exerce au Centre de gravité du boisThe traction is taken up exclusively by the wood, exerted at the center of gravity of the wood
La compression est reprise par le béton, la résultante des compressions s'exerce tout près de la fibre supérieure du plancher. On admet qu'elle s'exerce à 0.95 x l'épaisseur du plancherThe compression is taken up by the concrete, the result of the compressions is exerted near the upper fiber of the floor. It is admitted that it is exercised at 0.95 x the thickness of the floor
Le béton ne résiste pas à la traction ; il est fissuré.Concrete does not resist traction; he is cracked.
C'est là où la pièce horizontale est interrompue que se situe la résultante critique du plancher : à cet endroit, c'est la pièce verticale de bois qui est sollicitée : elle a la même section, mais le bras de levier résistant est plus faible, parce que le centre de gravité de la pièce de bois est plus élevé.
La moitié de l'armature requise dans les zones de flexion maximale est prolongée jusqu'aux appuis.Half of the required reinforcement in the areas of maximum flexion is extended to the supports.
