Description

Elément de construction. Construction element.

Plus particulièrement, I'invention concerne des éléments de construction pour la couverture des toits, notamment pour le remplacement de tuiles. More particularly, the invention relates to building components for covering roofs, including the replacement of tiles.

Généralement, les toitures sont réalisées au moyen de tuiles en terre cuite. Generally, the roofs are made using clay tiles. Le plus souvent, ces tuiles sont posées sur un solivage qui nécessite une mise en oeuvre relativement longue et par conséquent, coûteuse. Most often, these tiles are laid on a joist that requires implementation relatively long and therefore costly. En outre, le matériau qui constitue les tuiles est fragile. In addition, the material forming the tile is fragile. Enfin, ce type de tuiles ne présente pas un bon coefficient d'isolation. Finally, this type of tile does not have a good coefficient of insulation.

Le problème que se propose de résoudre l'invention est de concevoir un élément de construction dont la structure est déterminée pour lui conférer un très bon pouvoir isolant. The problem to be solved by the invention is to design a component whose structure is determined to give it a very good insulation.

Un tel problème, selon l'invention, est résolu en ce que l'élément est exécuté sous forme d'une plaque en béton de pouzzolane dans l'épaisseur de laquelle est noyé un matériau isolant, les extrémités de la plaque présentant des formes complémentaires d'emboitement en combinaison avec des moyens de verrouillage par agrafage. Such a problem, according to the invention is solved in that the element is constructed as a concrete slab pozzolan in the thickness of which is embedded an insulating material, the ends of the plate having complementary shapes fitting in combination with snap lock means.

Avantageusement, mais non limitativement, le béton de pouzzolane est obtenu par un mélange de pouzzolane et de ciment très homogène, déterminé pour avoir de bonnes caractéristiques mécaniques, tout en étant stable dans le temps. Advantageously, but not limited to, concrete pozzolan is obtained by a mixture of pozzolan cement and very homogeneous, determined to have good mechanical properties, while being stable over time. Le procédé de préparation d'un tel mélange est décrit dans la demande de brevet français 9003850, dont le demandeur de la présente est également titulaire. The method for preparing such a mixture is described in the French patent application 9003850, the applicant of the present also holds.

Un autre problème que se propose de résoudre l'invention, compte-tenu de l'importance de l'isolation de l'élément, est de pouvoir le rendre chauffant. Another problem to be solved by the invention, given the importance of the isolation of the element, is to make heating.

Ce problème est résolu en ce que la plaque présente dans son épaisseur au moins un tube pour la circulation d'un fluide. This problem is solved in that the plate has in its thickness at least one tube for circulating a fluid.

L'une des extrémités du ou des tubes apparait en débordement de l'un des bords de la plaque, tandis que l'autre extrémité apparait en retrait d'un bord opposé pour permettre, après emboitement des plaques, I'accouplement des extrémités correspondantes du ou des tubes. One of the ends of the tubes or appears protruding from one edge of the plate, while the other end is indented to an opposing edge to allow, after interlocking of the plates, corresponding ends I'accouplement the or tubes.

Un autre problème que se propose de résoudre l'invention est de pouvoir assembler les éléments entre eux d'une manière parfaitement étanche. Another problem to be solved by the invention is to assemble the elements together in a watertight manner.

Dans ce but, les formes complémentaires d'emboitement de la plaque sont exécutée à chacune des extrémités, respectivement sur les faces de dessus et de dessous de la plaque. For this purpose, the additional forms of interlocking of the plate are performed at each of the ends, respectively on the faces of top and bottom of the plate.

Pour résoudre le problème posé d'obtenir un assemblage parfaitement sûre et efficace des éléments entre eux, les moyens sont constitués par des profilés sous forme de lames-ressort qui sont établies en débordement de l'une des extrémités de la plaque, en étant maintenues par une barre d'accrochage, établie sur la quasi totalité de la longueur de l'élément, ces lames-ressort coopèrant avec des logements complémentaires établis à l'autre extrémité d'un élément adjacent. To solve the problem of obtaining a perfectly safe and effective assembly of the elements between them, the means are formed by profiled in the form of leaf springs which are established protruding from one end of the plate, being maintained by a hook bar, established over almost entire length of the element, these leaf springs cooperating with complementary housings established at the other end of an adjacent element.

Pour résoudre le problème posé d'assurer le positionnement des éléments sur le support, la face de dessous de la plaque présente en débordement, des parties profilées faisant office de butée, aptes à coopérer avec des moyens que présentent un support devant recevoir les éléments de construction. To solve the problem of ensuring the positioning of elements on the support, the underside of the plate has overflowed, the profiled parts forming a stop, able to cooperate with means that provide a support to receive the elements of construction.

Avantageusement, pour obtenir une très bonne isolation, le matériau isolant est une plaque de polystyrène expansé. Advantageously, to obtain a very good insulation, the insulating material is an expanded polystyrene plate.

L'invention est exposée, ci-après plus en détail à l'aide des dessins annexés, dans lesquels: The invention is explained below in more detail in the accompanying drawings, wherein:
La figure 1 est une vue en plan d'une forme de réalisation d'un élément de construction. Figure 1 is a plan view of one embodiment of a building element.

La figure 2 est une vue en coupe considérée selon la ligne 2-2 de la figure 1. Figure 2 is a sectional view taken along line 2-2 of Figure 1.

La figure 3 est une vue en coupe considérée selon la ligne 3-3 de la figure 1. Figure 3 is a sectional view taken along line 3-3 of Figure 1.

La figure 4 montre l'assemblage des panneaux entre eux. Figure 4 shows the assembly of the panels together.

Comme le montre la figure 1, chaque élément de construction est exécuté sous forme d'une plaque (1) en béton de pouzzolane, dans l'épaisseur de laquelle est noyé un matériau isolant (2). As shown in Figure 1, each building element is constructed as a plate (1) concrete pozzolan in the thickness of which is embedded an insulating material (2).

A titre indicatif, le béton de pouzzolane peut être obtenu de la manière suivante, telle qu'enseignée par la demande de brevet 9003850: - prélèvement d'une quantité de pouzzolane, - mesure de l'hygrométrie des agrégats de pouzzolane, - mélange et malaxage de la quantité de pouzzolane prévelée, - mesure de l'hygrométrie de la quantité de pouzzolane mélangée, - mélange de la pouzzolane malaxée avec une certaine quantité d'eau avec brassage homogène des agrégats de la pouzzolane et de l'eau, - malaxage du mélange de pouzzolane avec une quantité de ciment. By way of indication, concrete pozzolan can be obtained in the following way, as taught by the patent application 9003850: - removal of a quantity of pozzolan, - measuring the humidity of pozzolanic aggregates, - mixture and mixing the quantity of pozzolan prévelée, - measuring the humidity of the quantity of pozzolan mixed, - mixture of pozzolan kneaded with a certain amount of water with homogeneous mixing of aggregates of pozzolan and water, - mixing the pozzolanic admixture with cement.

Le matériau isolant (2) est avantageusement constitué par une couche de polystyrène expansé. The insulating material (2) is advantageously formed by a layer of expanded polystyrene. Cette couche (2) est insérée lors du moulage de la plaque (1) en béton de pouzzolane. This layer (2) is inserted during molding of the plate (1) concrete pozzolan.

Suivant une autre caractéristique, les extrémités de la plaque présentent des formes complémentaires d'emboîtement (1 a) et (1 b) en combinaison avec des moyens de verrouillage, par agrafage. According to another feature, the ends of the plate have complementary interlocking shapes (1a) and (1b) in combination with locking means, by stapling. Dans ce but et comme le montre notamment la figure 4, les formes complémentaires d'emboitement (1 a) et (1b) sont exécutées à chacune des extrémitées, respectivement sur les faces de dessus et de dessous de la plaque. For this purpose and as shown in particular in Figure 4, the interlocking of complementary shapes (1a) and (1b) are performed at each of extrémitées respectively on the faces of top and bottom of the plate.

Par exemple, la forme (1 a) apparait au niveau de la face de dessous de la plaque (1), tandis que la forme (lob) apparait au niveau de la face de dessus. For example, the form (1 a) appears at the underside of the plate (1), while the shape (lob) appears at the top face. Chacune de ces formes est en retrait du plan défini par la face correspondante de la plaque, pour permettre, après emboitement desdites formes, le positionnement dans un même plan des plaques. Each of these forms is recessed from the plane defined by the corresponding face of the plate, to allow, after said interlocking shapes, positioning in the same plane of the plates. De préférence, ces formes complémentaires (1 a) et (1 b) sont formées du côté des bords latéraux de la plaque. Preferably, these complementary forms (1a) and (1b) are formed on the side of the lateral edges of the plate.

A noter que les mêmes dispositions ou, des dispositions équivalentes, peuvent être faites au niveau des bords transversaux de la plaque. Note that the same provisions or equivalent arrangements can be made at the transverse edges of the plate. Par exemple, comme le montre la figure 2, les bords transversaux présentent des profils complémentaires d'assemblage et de positionnement (nid) et (lue). For example, as shown in Figure 2, the transverse edges have complementary connecting profiles and positioning (nest) and (luc).

Comme indiqué, les formes complémentaires d'emboitement (la) et (lb) présentent des moyens de verrouillage par agrafage. As indicated, the additional forms of interlocking (Ia) and (Ib) have snap lock means. Ces moyens sont constitués par des profilés sous forme de lames-ressort (3) . These means are constituted by profiles in the form of leaf springs (3). Ces lames-ressort sont établies en débordement de l'une des extrémités de la plaque, en étant maintenues par une barre These leaf springs are established protruding from one end of the plate, being maintained by a bar
I'une des extrémités de la plaque, en étant maintenues par une barre d'accrochage (4), établie sur la quasi totalité de la longueur de l'élément. I'une the ends of the plate, being maintained by a hook bar (4), established on the almost entire length of the element.

Ces lames-ressort (3) coopèrent dans des logements complémentaires (5) établis à l'autre extrémité d'un élément adjacent. These leaf springs (3) engage in complementary recesses (5) established at the other end of an adjacent element.

Suivant une autre caractéristique importante de l'invention, la plaque ainsi définie présente dans son épaisseur, au moins un tube (6) pour la circulation d'un fluide, notamment de l'air chaud. According to another important feature of the invention, the plate has thus defined in its thickness, at least one tube (6) for the circulation of a fluid, in particular hot air. L'une des extrémités (6a) du ou des tubes (6) apparait en débordement de l'un des bords de la plaque (1). One of the ends (6a) of the tube or tubes (6) appears at the overflow of one of the edges of the plate (1). L'autre extrémité (6b) du ou des tubes3 apparait en retrait du bord opposé, pour permettre après emboitement des plaques, I'accouplement des extrémités correspondantes des tubes (6). The other end (6b) of the or tubes3 appears behind the opposite edge, to allow after interlocking of the plates, I'accouplement corresponding ends of the tubes (6). Après assemblage des plaques, les différents tubes (6) peuvent constituer un circuit pour la circulation du fluide assujetti à tout moyen, tel que ventilateur. After assembly of the plates, the individual tubes (6) may constitute a circuit for the circulation of fluid subject to any means, such as fan.

La face de dessous de la plaque (1) présente en débordement, des parties profilées (if) faisant office de butée ou de talon en étant apte à coopérer avec des moyens que présente le support devant recevoir l'ensemble des éléments de construction selon l'invention. The underside of the plate (1) has overflowed, the profiled portions (if) acting as a stop or bead office being adapted to cooperate with means that present the carrier before receiving the set of building elements according to 'invention. Dans le cas d'une utilisation des éléments pour la couverture des toits3 le talon (if) peut coopérer directement avec les parties correspondantes de la charpente. In the case of a use of elements to cover the heel toits3 (if) can cooperate directly with corresponding portions of the framework.

Les avantages ressortent bien de la description, en particulier on rappelle et on souligne: The advantages are apparent from the description, in particular, reminds and stresses:
- L'isolation obtenue par la combinaison du béton de pouzzolane et du matériau isolant incorporé dans l'épaisseur dudit béton. - The insulation obtained by the combination of concrete pozzolan and insulating material incorporated in the thickness of said concrete.

- La facilité de pose. - The ease of installation.

- L'étanchéité obtenue après assemblage des éléments. - The tightness obtained after assembly of the elements.

- La possibilité de faire circuler un fluide. - The possibility of circulating a fluid.

- La suppression du solivage dans le cas d'une utilisation des éléments en tant que tuiles. - The removal of the joists in the case of use of the elements as tiles.

Bien évidemment, les plaques telles que définies, peuvent être exécutées en toutes formes et dimensions, en fonction des applications envisagées. Obviously, the plates as defined, can be executed in all shapes and sizes, depending on the intended applications. De même, la plaque peut présenter un revêtement extérieur quelconque. Similarly, the plate may have any outer coating.

Enfin, compte-tenu des caractéristiques définies de la plaque, cette dernière trouve une application avantageuse pour la couverture de toits, ainsi qu'en habillage de façades. Finally, given the features defined in the plate, the latter is advantageously applicable for covering roofs, as well as façade cladding.
