Description
Dalle On connaît les risques de détérioration des dalles de marbre, au cours des travaux de dégrossissage, de polissage et de coupe ainsi qu'au cours de leur trans port des ateliers de marbrerie sur les chantiers. Jus qu'à présent, tous les marbres, et plus particulière ment les marbres de couleur qui sont les plus pré cieux (rose de Jannina, vert de Tinos, noir de Vy- tina, rouge du Magne, rose d'Astakos, les marbres des régions de Domvraina, Thèbes et Arachova et, dans une proportion moindre, les marbres blancs et gris), au cours des opérations de dégrossissage,
de polissage et de découpage qu'ils subissent dans les marbreries après leur extraction, puis au cours de leur transport sur les différents chantiers et de leur mise en place définitive, présentent une perte qui, le plus souvent atteint 40 % de la quantité extraite.
A cause des risques de détérioration et pour ré pondre à certaines exigences de résistance méca nique, l'épaisseur des dalles connues est relativement importante. Elle comporte au minimum 20 mm pour satisfaire aux besoins du marché.
Enfin, en ce qui concerne les dalles pour revête ments muraux, l'épaisseur nécessaire d'au moins 30 mm correspond aux moyens de fixations utilisés, qui le plus souvent doivent être noyés dans l'épaisseur même de la dalle.
La présente invention a précisément pour objet une dalle obviant à ces inconvénients. Cette dalle est caractérisée par une plaque de marbre dont une face est recouverte d'une couche de matière de renforce ment.
Les dessins annexés représentent, à titre d'exem ple, trois formes d'exécution de la présente invention. La fig. 1 est une vue en perspective d'une pre mière forme d'exécution. La fig. 2 est une vue semblable d'une deuxième forme d'exécution.
Les fig. 3 et 4 sont des vues semblables, de des sous et de dessus d'une troisième forme d'exécution. Les fig. 5, 6 et 7 sont des coupes transversales des trois formes d'exécution mentionnées.
Comme on le voit au dessin, la dalle se compose d'une plaque de marbre 1 et d'une couche de ren forcement 2. Cette couche de renforcement peut être constituée par du béton ordinaire ou du béton de pierre ponce, pourvue ou non d'une armature. L'épaisseur de la couche de renforcement est va riable, suivant l'usage pour lequel la dalle est pré vue ainsi que suivant ses dimensions.
On voit à la fig. 2 une telle armature constituée par des fers 3.
La fixation de la couche de renforcement peut se faire selon un procédé connu, tel que par pressage, par pervibration, par l'un et l'autre combinés ou par moulage. Le travail de fixation de la couche de ren forcement est exécuté, après extraction de la dalle, par l'atelier où les marbres sont débités.
Une telle couche de renforcement offre l'avan tage de rendre possible l'utilisation de dalles de marbre d'une épaisseur minime, cette épaisseur étant déterminée par les possibilités de coupe des ateliers spécialisés. Elle neutralise entièrement les risques de détériorations des dalles de marbre au cours des tra vaux de dégrossissage, de polissage et de coupe aux formes et dimensions voulues, de même qu'au cours de leur transport des ateliers de marbrerie sur les chantiers.
Elle donne enfin la possibilité d'employer pour le revêtement de murs et de parois, où des or ganes de fixation doivent être noyés dans la dalle, des dalles d'épaisseur minime, par exemple de 4 mm. En effet, des crochets de fixation 4, 5 tels que repré sentés aux fig. 4 et 6, sont noyés dans la couche de renforcement elle-même pour fixer la dalle contre une paroi.
Lorsque les conditions d'utilisation l'exigent, et pour augmenter la résistance mécanique des dalles de marbre ainsi renforcées, le béton de renforcement peut être armé. On comprend les avantages qu'offre une telle dalle de marbre pour l'exploitation rationnelle des carrières de marbre ainsi que pour l'obtention dans les plus grandes dimensions de dalles à un prix de revient raisonnable.
Le renforcement de la dalle peut bien entendu être obtenu par d'autres matières que le béton, le bé ton armé ou le béton de pierre ponce, notamment par du ciment expandé allié à du liège broyé, à des fibres de bois ou de la vermiculite, et par d'autres matières.
Slab We know the risks of deterioration of marble slabs during roughing, polishing and cutting work as well as during their transport from marble workshops to construction sites. Until now, all the marbles, and more particularly the colored marbles which are the most precious (rose of Jannina, green of Tinos, black of Vy- tina, red of Mani, rose of Astakos, the marbles regions of Domvraina, Thebes and Arachova and, to a lesser extent, white and gray marbles), during roughing operations,
polishing and cutting that they undergo in marble works after their extraction, then during their transport to the various sites and their final installation, present a loss which, most often reaches 40% of the quantity extracted.
Because of the risks of deterioration and to meet certain mechanical strength requirements, the thickness of known slabs is relatively large. It has a minimum of 20 mm to meet market needs.
Finally, with regard to slabs for wall coverings, the necessary thickness of at least 30 mm corresponds to the means of fastening used, which most often must be embedded in the thickness of the slab itself.
The object of the present invention is precisely a panel which obviates these drawbacks. This slab is characterized by a marble slab, one side of which is covered with a layer of reinforcing material.
The accompanying drawings show, by way of example, three embodiments of the present invention. Fig. 1 is a perspective view of a first embodiment. Fig. 2 is a similar view of a second embodiment.
Figs. 3 and 4 are similar views, from below and from above, of a third embodiment. Figs. 5, 6 and 7 are cross sections of the three embodiments mentioned.
As can be seen in the drawing, the slab consists of a marble slab 1 and a reinforcing layer 2. This reinforcing layer can be constituted by ordinary concrete or pumice concrete, with or without 'a frame. The thickness of the reinforcing layer is variable, depending on the use for which the slab is intended as well as depending on its dimensions.
We see in fig. 2 such a frame constituted by irons 3.
The fixing of the reinforcing layer can be done according to a known method, such as by pressing, by pervibration, by one and the other combined or by molding. The work of fixing the reinforcing layer is carried out, after extraction of the slab, by the workshop where the marbles are cut.
Such a reinforcing layer offers the advantage of making possible the use of marble slabs of minimal thickness, this thickness being determined by the cutting possibilities of specialized workshops. It completely neutralizes the risk of deterioration of marble slabs during roughing, polishing and cutting to the desired shapes and sizes, as well as during their transport from marble workshops to construction sites.
Finally, it gives the possibility of using, for the covering of walls and walls, where fixing elements have to be embedded in the slab, slabs of minimal thickness, for example 4 mm. Indeed, fixing hooks 4, 5 as shown in FIGS. 4 and 6, are embedded in the reinforcing layer itself to fix the slab against a wall.
When the conditions of use so require, and to increase the mechanical resistance of the marble slabs thus reinforced, the reinforcing concrete can be reinforced. We understand the advantages offered by such a marble slab for the rational exploitation of marble quarries as well as for obtaining slabs in the largest dimensions at a reasonable cost price.
The reinforcement of the slab can of course be obtained by other materials than concrete, reinforced concrete or pumice concrete, in particular by expanded cement combined with crushed cork, wood fibers or vermiculite , and by other matters.
