Description

Dalles préfabriquées.Prefabricated slabs.

On a déjà proposé de réaliser des dalles qui présentent l'apparence de dalles en pierre naturelle et qui sont réalisées par moulage de compositions à base de matières plastiques et de divers matériaux de charge. It has already been proposed to produce slabs which have the appearance of natural stone slabs and which are made by molding compositions based on plastics and various filler materials.

Les dalles connues de ce genre présentent cependant l'inconvénient de devoir être fabriquées dans un moule dont les surfaces internes doivent être parfaitement polies pour donner à la dalle un fini extérieur qui imite convenablement la pierre polie. Known slabs of this type, however, have the drawback of having to be manufactured in a mold, the internal surfaces of which must be perfectly polished to give the slab an exterior finish which suitably imitates polished stone.

Le procédé qui permettrait d'obtenir de telles dalles consiste principalement à disposer dans le moule et successivcment, les différentes couches de matériaux devant constituer la dalle, en commençant le plus souvent par la couche devant constituer la face extérieure de la dalle. The process which would make it possible to obtain such slabs consists mainly in placing in the mold and successively, the various layers of materials which are to constitute the slab, most often starting with the layer which must constitute the outer face of the slab.

Non seulement ce procédé connu est relativement onéreux en raison de la nécessité d'utiliser des moules du genre susvisé, mais il est également long à mettre en ceuvre et par conséquent les dalles obtenues sont d'un prix de revient relativement élevé. Not only is this known process relatively expensive because of the need to use molds of the aforementioned type, but it is also long to implement and consequently the slabs obtained have a relatively high cost price.

La présente invention a pour objet une dalle de ce genre qui soit plus facile à obtenir et d'un prix de revient plus faible tout en présentant un aspect extérieur impeccable et des qualités au moins égales sinon accrues de résistance au vieillissement et aux intempéries. Elle a également pour but un procédé de fabrication de dalles de ce genre. The present invention relates to a slab of this type which is easier to obtain and of a lower cost price while having an impeccable exterior appearance and at least equal if not increased qualities of resistance to aging and weathering. It also aims at a method of manufacturing slabs of this kind.

Une dalle conforme à l'invention se caractérise essentiellement par le fait de comporter successivement une couche extérieure d'une seule pièce comportant une grande face et les quatre petits côtés de la dalle et qui est obtenue par formage d'une feuille de matière plastique connue sous le nom de Plexiglass (marque déposée), une couche de résistance disposée parallèlement et au voisinage de la grande face de cette dalle et une couche de matière de charge constituée par des gravillons calibrés agglomérés à l'aide d'une résine synthétique. A slab according to the invention is essentially characterized by the fact of successively comprising an outer layer of a single piece comprising a large face and the four small sides of the slab and which is obtained by forming a known plastic sheet. under the name of Plexiglass (registered trademark), a resistance layer arranged parallel to and in the vicinity of the large face of this slab and a layer of filler material consisting of calibrated chippings agglomerated using a synthetic resin.

Le procédé conforme à l'invention consiste essentiellement à réaliser tout d'abord une boîte sans couvercle, ayant les dimensions de la dalle à fabriquer par emboutissage, ou formage sous vide, dnune feuille d'épaisseur convenable de la matière plastique vendue sous la marque déposée Plexiglass , à appliquer ensuite sur le fond de cette boîte une armature avantageusement constituée par une nappe de fibre de verre ou de mat de verre convenablement imprégnée de résine synthétique, par exemple, la résine vendue par les etcs Routan sous la dénomination H 200 et à finir de remplir cette boîte avec la matière de charge que l'on obtient en mélangeant une résine synthétique et du gravillon. The method according to the invention essentially consists in first producing a box without a cover, having the dimensions of the slab to be manufactured by stamping, or vacuum forming, from a sheet of suitable thickness of the plastic material sold under the brand name. deposited Plexiglass, to then apply on the bottom of this box a reinforcement advantageously constituted by a sheet of fiberglass or glass mat suitably impregnated with synthetic resin, for example, the resin sold by etcs Routan under the name H 200 and to finish filling this box with the filler material obtained by mixing a synthetic resin and gravel.

C'est la surface extérieure de cette matière de charge qui constitue la deuxième grande face de la dalle conforme à l'invention. It is the outer surface of this filler material which constitutes the second large face of the slab according to the invention.

On conçoit donc que l'on peut complètement éviter l'utilisation d'un moule puisque la feuille de plexiglass constituant les faces extérieures apparentes de la dalle constitue elle-même le moule individuel de chaque dalle. It is therefore understood that the use of a mold can be completely avoided since the sheet of plexiglass constituting the visible outer faces of the slab itself constitutes the individual mold of each slab.

D'autres caractéristiques et avantages de l'invention ressortiront de la description qui va suivre, faite en référence aux dessins annexés, donnés à titre d'exemple non limitatif et dans lesquels
La figure 1 est une vue en perspective d'une feuille de plexiglass formée selon la présente invention, en ve de l'obtention d'une dalle;
La figure 2 est une coupe transversale d'une dalle obtenue conformément à l'invention.Other characteristics and advantages of the invention will emerge from the description which follows, given with reference to the appended drawings, given by way of non-limiting example and in which
FIG. 1 is a perspective view of a sheet of plexiglass formed according to the present invention, with a view to obtaining a slab;
FIG. 2 is a cross section of a slab obtained in accordance with the invention.

Comme le montre la figure 1, une dalle conforme à l'invention est obtenue tout d'abord en moulant tà la presse ou en conformant de toute autre manière convenable, une feuille de plexiglass d'épaisseur convenable qui se trouvera constituer la grande face 1 et les faces latérales 2, 3, 4 et 5 de la dalle terminée. On peut, si on le désire, projeter au pistolet, à lintérieur de la capacité ainsi obtenue, As shown in Figure 1, a tile according to the invention is obtained first of all by molding tà the press or by shaping in any other suitable way, a sheet of plexiglass of suitable thickness which will be found to constitute the large face 1 and the side faces 2, 3, 4 and 5 of the finished slab. It is possible, if desired, to project with a pistol, within the capacity thus obtained,

Claims (1)

soit une couche colorée noire contenant éventuellement des paillettes de mica, soit une couche analogue de couleur quelconque en vue de donner à la dalle terminée l'aspect du granit, du marbre ou d'une autre pierre. either a black colored layer optionally containing mica flakes, or an analogous layer of any color in order to give the finished slab the appearance of granite, marble or another stone. On applique ensuite une couche 6 de résistance qui est constituée par du mat de fibre de verre, du tissu de verre ou autre matière analogue convenablement imprégnée de résine synthétique et par exemple de la résine indiquée ci-dessus. A resistance layer 6 is then applied which is constituted by a mat of glass fiber, glass cloth or other similar material suitably impregnated with synthetic resin and for example the resin indicated above. La dernière phase du procédé consiste à finir de remplir la capacité par une masse 7 constituée d'un mélange de résine synthétique et de gravillons. Par exemple, cette résine synthétique peut être celle vendue par les Ets Routan sous la dénomination H200 et dont on utilise une partie pour cinq parties de gravillons calibres à 2 mm de diamètre ou moins; cette résine a été préalablement additionnee d'un catalyseur et d'un accélérateur, dans des proportions qui sont bien connues des spécialistes. The last phase of the process consists in finishing filling the capacity with a mass 7 consisting of a mixture of synthetic resin and gravel. For example, this synthetic resin can be that sold by Ets Routan under the name H200 and of which one part is used for five parts of gravel sized 2 mm in diameter or less; this resin has been previously added with a catalyst and an accelerator, in proportions which are well known to specialists. La capacité formée par l'embout en plexiglas est remplie a' ras-bords de cette composition que l'on laisse faire prise pendant par exemple environ 24 heures. On conçoit alors que les couches extérieures de plexiglass et de la composition constitue avec la couche de résistance 6 une masse compacte parfaitement resistante et que l'on peut utiliser comme une dalle de pierre, par exemple pour la construction de monuments funéraires, le revêtement de fa çades, etc. The capacity formed by the plexiglass tip is filled to the brim with this composition which is left to set for, for example, about 24 hours. It is then understood that the outer layers of plexiglass and of the composition together with the resistance layer 6 constitute a perfectly resistant compact mass and which can be used as a stone slab, for example for the construction of funerary monuments, the coating of facades, etc. Le mode d'exécution de l'invention qui vient d'être decrit ne ra été qu'à titre d'exemple non limai tatif et l'on peut lui apporter toutes modifications de détail sans sortir pour cela du cadre de Pinven- tion. The embodiment of the invention which has just been described was only by way of non-limiting example and any modifications of detail can be made to it without thereby departing from the scope of the invention. En particulier, on peut projeter sur la face interne de la capacité en plexiglas une mince couche de résine colorée d'une manière quelconque ou d'un mélange grossier de résine de coloration différente afin d'imiter toutes les pierres généralement utilisées pour la fabrication des dalles. In particular, one can project on the internal face of the plexiglass capacity a thin layer of resin colored in any way or of a coarse mixture of resin of different coloring in order to imitate all the stones generally used for the manufacture of slabs.
