Abstract

The mushroom floor which is carried by pillars (7) is composed of superposed prefabricated plates (1,2,3,4,5) to receive compression flooring (6) in order to obtain a variable thickness slab.

Description

- PLANCHER-CHAMPIGNONS - La présente invention concerne la disposition d'éléments préfabriqués en béton, superposés appelés prédelles, propres à réaliser un plancher-champignons, sans poutres, à chapiteaux disposés en tête de pilier, en faisant l'économie du coffrage. Ce type de plancher existe depuis longtemps. - FLOOR-MUSHROOMS - The present invention relates to the provision of prefabricated concrete elements, superimposed called predelles, suitable for producing a mushroom floor, without beams, with capitals arranged at the head of a pillar, saving the formwork. This type of floor has been around for a long time.

C'est un principe constructif objectivement intéressant, permettant de franchir des portées de 6 à 18 m qui comporte, en travée, une faible épaisseur et qui est économe de matière. Actuellement, il est rarement usité, car sa mise en oeuvre est longue et son prix élevé. This is an objectively interesting constructive principle, making it possible to cross spans from 6 to 18 m which has a small thickness in the span and which is economical in terms of material. Currently, it is rarely used, because its implementation is long and its price is high.

Notre système se propose de remédier à ces deux inconvénients. II s'agit de réaliser un plancher, (voir fig 1) avec prédelles et chape de compression; (voir fig 2) au résultat, la dalle finie aura une épaisseur variable, statiquement nécessaire et suffisante suivant les zones. Our system proposes to remedy these two drawbacks. It is a question of making a floor, (see fig 1) with predales and compression yoke; (see fig 2) As a result, the finished slab will have a variable thickness, statically necessary and sufficient depending on the zones.

Les plus grandes prédelles, situées en travées, ont une longueur égale au 5I7 de la portée,(voir fig 3 et 4) c'est à dire que le joint entre les prédelles est situé à une distance du pilier égale à 1l7 de la portée. Le chapiteau d'un pilier intérieur est un tronc de pyramide (1) ou un tronc de cône dont la petite base est la section supérieure de la partie prismatique du pilier.(7) En variante, ce chapiteau peut-être constitué d'au moins une prédelle (2) (3) ayant la forme d'un parallélépipède. The largest predellae, located in spans, have a length equal to 5I7 of the span, (see fig 3 and 4) i.e. the joint between the predellae is located at a distance from the pillar equal to 11l7 of the span . The capital of an interior pillar is a pyramid trunk (1) or a truncated cone whose small base is the upper section of the prismatic part of the pillar. (7) As a variant, this capital can be made up of at least minus a predella (2) (3) having the shape of a parallelepiped.

Les éléments préfabriqués sont en béton-armé, béton précontraint plein ou alvéolaire. Le processus de réalisation est le suivant - Fabrication en atelier de prédelles (1 à 5); - Comportant des aciers, propres à satisfaire les règles parasismiques. - En chapiteaux, pose des prédelles (2), (3). The prefabricated elements are in reinforced concrete, solid pre-stressed concrete or cellular. The production process is as follows - Manufacture in a predella workshop (1 to 5); - Containing steels, suitable for satisfying earthquake-resistant rules. - In capitals, pose predelles (2), (3).

- En appui sur ces dernières, pose des prédelles de la bande dite d'appui. (4) - En appui sur ces dernières, pose des prédelles de la bande, dite centrale. (5) - Pose des aciers supérieurs et bétonnage de la chape de compression.(6) Ainsi, on réalise un plancher-champignons à épaisseur variable par zone. Selon un cas particulier de réalisation, à titre d'exemple non limitatif, et en référence aux dessins annexés, on constate pour une portée L1 = LZ = 8,00 m. - By pressing on the latter, poses predelles of the so-called support strip. (4) - Pressing on the latter, poses predelles of the band, called the central one. (5) - Installation of upper steels and concreting of the compression screed. (6) Thus, a mushroom floor is produced with variable thickness by area. According to a particular embodiment, by way of nonlimiting example, and with reference to the accompanying drawings, there is for a range L1 = LZ = 8.00 m.

* La dimension de la première prédelle du chapiteau : 140 x 140 (2) * La dimension de la deuxième prédelle du chapiteau : 250 x 250 (3) * La dimension de la prédelle de bande dite d'appui : 570 x 250 (4) * La dimension de la prédelle de bande dite centrale : 570 x 570 (5) * La chape de compression (6) d'épaisseur variable suivant les zones * Des joints situés à une distance de l'axe du pilier (7) de L17, soit environ 1,25 m * Un recouvrement des prédelles de 10 cm.  * The dimension of the first predella of the marquee: 140 x 140 (2) * The dimension of the second predella of the marquee: 250 x 250 (3) * The dimension of the predella of the so-called support strip: 570 x 250 (4 ) * The size of the so-called central strip predella: 570 x 570 (5) * The compression yoke (6) of variable thickness depending on the area * Joints located at a distance from the axis of the pillar (7) L17, about 1.25 m * An overlap of the predellae of 10 cm.

* Une épaisseur totale du plancher qui varie suivant les zones de 50 à 16 cm.  * A total thickness of the floor which varies according to the zones from 50 to 16 cm.

Ainsi, ce plancher allie-t-il les qualités afférentes aux dalles pleines et aux dalles à inertie variable, gage d'économie.Thus, this floor combines the qualities of solid slabs and slabs with variable inertia, a guarantee of economy.
