Description

Procédé de fabrication de pierres artificielles et pierres artificieLles obtenues par sa mise en oeuvre.Process for manufacturing artificial stones and artificial stones obtained by its implementation.

La présente invention concerne un procédé de fabrication de pierres artificielles. Elle vise également
Les pierres artificielles ou éléments en pierre artificielle obtenus par la mise en oeuvre de ce procédé.The present invention relates to a method for manufacturing artificial stones. It also targets
Artificial stones or artificial stone elements obtained by the implementation of this process.

De manière plus particulièrement intéressante quoique non limitative, Le procédé selon l'invention peut être appliqué à la fabrication de pierres artificielles ayant l'apparence des pierres calcaires fossilisées telle que les pierres connues sous Les noms de pierre du Gard ou de pierre du Vaucluse ou de Provenue, lesquelles ont un aspect ornemental remarquable. More particularly advantageously, although not limiting, The method according to the invention can be applied to the manufacture of artificial stones having the appearance of fossilized limestone such as stones known under the names of Gard stone or Vaucluse stone or from Provenue, which have a remarkable ornamental aspect.

Ces pierres calcaires fossilisées, comme la plupart des pierres naturelles traditionnellement utilisées dans l'industrie du bâtiment, présentent plusieurs inconvénients contraignants : elles doivent être extraites et travaiLlées en carrière dans des conditions souvent pénibles ; elles sont lourdes et nécessitent l'emploi de matériels de manutention et de transport puissants et coûteux ; leur façonnage par sciage mécanique ne permet d'obtenir que des blocs ou éléments ayant des formes géométriques simples, généralement parallélépipédiques, et entraine, en outre, des pertes relativement importantes de matériau ; elles ont des caractéristiques d'isolation médiocre. These fossilized limestones, like most natural stones traditionally used in the building industry, have several constraining drawbacks: they must be extracted and worked in a quarry under often painful conditions; they are heavy and require the use of powerful and expensive handling and transport equipment; their shaping by mechanical sawing makes it possible to obtain only blocks or elements having simple geometric shapes, generally parallelepipedic, and also causes relatively large losses of material; they have poor insulation characteristics.

On connait différents procédés de fabrication de pierres artificielles. Toutefois, les pierres artificielles obtenues par la mise en oeuvre des procédés connus présentent souvent certains inconvénients propres aux pierres naturelles (lourdeur, mauvaise isolation, etc.) et/ou ont un aspect qui révèle leur facticité. Par exemple, ces procédés ne permettent pas de fabriquer des pierres artificielles ayant l'apparence des pierres calcaires fossilisées telles que La pierre du Gard, ou la pierre du
Vaucluse.We know different processes for making artificial stones. However, the artificial stones obtained by the implementation of known methods often have certain drawbacks specific to natural stones (heaviness, poor insulation, etc.) and / or have an appearance which reveals their facticity. For example, these methods do not make it possible to manufacture artificial stones having the appearance of fossilized limestone such as La pierre du Gard, or pierre du
Vaucluse.

L'invention a notamment pour but de remédier aux inconvénients susmentionnés des procédés de fabrication de pierres artificielles connus. The object of the invention is in particular to remedy the aforementioned drawbacks of the processes for manufacturing known artificial stones.

Selon l'invention, cet objectif est atteint grâce à un procédé suivant lequel - on confectionne une empreinte, par exemple sous forme de moule, présentant une forme appropriée à celle des éléments à obtenir et dont la surface opérante reproduit, en négatif, le grain de la pierre artificielle à réaliser ; - on prépare un gâchis ou mortier à base de ciment ou de plâtre ; - on procède au moulage de ce gâchis ou mortier à L'aide de ladite empreinte ; - on sépare La pièce obtenue, de cette dernière ; - on applique au moins un produit de coloration sur au moins une surface ou parement de cette pièce moulée ; - après séchage de ce produit, on effectue un grattage superficiel de La surface teintée. According to the invention, this objective is achieved thanks to a process according to which - an imprint is made, for example in the form of a mold, having a shape suitable for that of the elements to be obtained and the operating surface of which reproduces, in negative, the grain artificial stone to be made; - preparing a mess or mortar based on cement or plaster; - We proceed to molding this mess or mortar using said imprint; - The part obtained is separated from the latter; - At least one coloring product is applied to at least one surface or facing of this molded part; - After drying of this product, a surface scraping of the tinted surface is carried out.

Selon une autre disposition caractéristique du procédé de l'invention, l'empreinte est façonnée par moulage sur une pierre naturelle ou sur une pierre artificielle présentant un grain comparable à celui de cette pierre artificielle. According to another characteristic arrangement of the method of the invention, the imprint is shaped by molding on a natural stone or on an artificial stone having a grain comparable to that of this artificial stone.

Selon une autre disposition caractéristique du procédé de l'invention, au moins la surface de parement de la pierre artificielle obtenue, est soumise à un traitement terminal de protection tel qu'un traitement hydrofuge et/ou ignifuge, par exemple appliqué par vaporisation ou par trempage. According to another characteristic arrangement of the process of the invention, at least the facing surface of the artificial stone obtained is subjected to a terminal protection treatment such as a water-repellent and / or fire-retardant treatment, for example applied by spraying or by soaking.

On obtient, grâce à la mise en oeuvre du procédé de l'invention, des pierres artificielles dont l'aspect est semblable à celui des pierres naturelles ayant servi de modèle à leur fabrication, ces pierres artificielles ayant l'avantage d'être plus légères et d'avoir de meilleures caractéristiques d'isolation que ces dernières, notamment de meilleures caractéristiques d'isolation thermique. Obtained, by implementing the method of the invention, artificial stones whose appearance is similar to that of natural stones used as a model for their manufacture, these artificial stones having the advantage of being lighter and to have better insulation characteristics than the latter, in particular better thermal insulation characteristics.

En outre, la mise en oeuvre du procédé selon l'invention consiste en une succession d'opérations simples, ne nécessitant pas l'emploi de matériel complexes et coûteux, et s'effectuant en utilisant des matériaux ou produits couramment employés dans l'industrie du bâtiment. In addition, the implementation of the method according to the invention consists of a succession of simple operations, not requiring the use of complex and expensive equipment, and carried out using materials or products commonly used in industry of the building.

De plus, on conçoit que Les pierres artificielles obtenues par moulage peuvent avoir une grande variété de formes
Les buts, caractéristiques et avantages ci-dessus, et d'autres encore, ressortiront mieux de la description qui suit et des dessins annexés dans lesquels
La figure 1 est une vue en coupe et à caractère schématique illustrant la confection d'un moule sur modèle.In addition, it is understood that the artificial stones obtained by molding can have a wide variety of shapes.
The objects, characteristics and advantages above, and others still, will emerge more clearly from the description which follows and from the appended drawings in which

La figure 7 est une vue à caractère schématique et en perspective illustrant l'application d'un traitement terminal de surface. Figure 7 is a schematic perspective view illustrating the application of a terminal surface treatment.

On se réfère auxdits dessins pour décrire un exemple de mise en oeuvre intéressant, quoique nullement limitatif, du procédé de fabrication de pierres artificielles selon l'invention. Reference is made to said drawings to describe an interesting example of implementation, although in no way limiting, of the method for manufacturing artificial stones according to the invention.

Selon ce procédé, on prépare d'abord une empreinte qui peut être constituée par un moule 1, ou par une matrice, cette empreinte présentant une forme appropriée à celle des éléments à réaliser et au moins une surface opérante 2 qui reproduit, en négatif, le grain (aspérités et creux) d'au moins une surface de La pierre artificielle à réaliser. According to this process, an impression is first prepared which can be constituted by a mold 1, or by a matrix, this impression having a shape suitable for that of the elements to be produced and at least one operating surface 2 which reproduces, in negative, the grain (roughness and hollow) of at least one surface of the artificial stone to be produced.

De manière caractéristique et avantageuse, le moule 1 ou autre empreinte, peut être obtenu par moulage sur la pierre naturelle dont on souhaite reproduire l'aspect, ou sur une pierre artificielle présentant un grain comparable à celui de cette pierre naturelle. Characteristically and advantageously, the mold 1 or other imprint can be obtained by molding on the natural stone of which it is desired to reproduce the appearance, or on an artificial stone having a grain comparable to that of this natural stone.

Par exemple, pour obtenir une pierre artificielle ayant
L'apparence de la pierre calcaire fossilisée dite "pierre du Gardtr, le moule 1 ou autre empreinte, est obtenu par moulage sur une pierre calcaire fossilisée naturelle de ce genre ou sur une pierre artificielle déjà réalisée et dont le grain est identique ou comparable à celui de cette pierre naturelle.For example, to obtain an artificial stone having
The appearance of the fossilized limestone called "Gardtr stone, mold 1 or other imprint, is obtained by molding on a natural fossilized limestone of this kind or on an artificial stone already made and whose grain is identical or comparable to that of this natural stone.

La figure 1 illustre le moulage d'un moule 1 sur une pierre naturelle 3, dans un cadre ou châssis 4 ; les parties gauche et droite de la figure, représentent, respectivement, le positionnement du modèle 3 dans le châssis 4 et le remplissage de celui-ci à L'aide du produit destiné à constituer le moule 1, ce produit pouvant être constitué par tous matériaux convenables, tels que : alliages métalliques, resines synthétiques, plâtre, etc. FIG. 1 illustrates the molding of a mold 1 on a natural stone 3, in a frame or chassis 4; the left and right parts of the figure, represent, respectively, the positioning of the model 3 in the chassis 4 and the filling thereof with the aid of the product intended to constitute the mold 1, this product being able to be constituted by all materials suitable, such as: metal alloys, synthetic resins, plaster, etc.

La figure 2 montre le moule 1 obtenu, après démoulage. Figure 2 shows the mold 1 obtained, after demolding.

On a représenté la fabrication et l'utilisation d'un moule de forme simple pour le moulage de pierres artificielles de forme parallélépipédique, mais on rappelle que ce moule, et plus précisément sa surface opérante 2, pourrait avoir des formes variées permettant le moulage de pierres artificielles de diverses formes (concave, convexe, etc.). The manufacture and use of a mold of simple shape has been shown for molding artificial stones of parallelepiped shape, but it is recalled that this mold, and more precisely its operating surface 2, could have various shapes allowing the molding of artificial stones of various shapes (concave, convex, etc.).

Après confection du moule 1, on prépare un gâchis ou mortier 5' à base de ciment, ou à base de plâtre, à L'ai de des matériels couramment employés pour l'obtention de teLs mélanges, dans le domaine de La construction. After making the mold 1, a mess or mortar 5 'is prepared based on cement, or based on plaster, using materials commonly used for obtaining such mixtures, in the field of construction.

Les mélanges à base de ciment ou à base de plâtre préparés par la mise en oeuvre du procédé de l'invention peuvent avantageusement comprendre un matériau isolant tels que : vermiculite, perlite, billes de polystyrène, copeaux de bois, amiante, fibres de verre, Laine de verre, paille compressée, etc. The cement-based or plaster-based mixtures prepared by implementing the process of the invention can advantageously comprise an insulating material such as: vermiculite, perlite, polystyrene beads, wood chips, asbestos, glass fibers, Glass wool, compressed straw, etc.

Ils peuvent également inclure un ou plusieurs des produits ci-après : agrégats naturels ou concassés (sable, gravier, pouzzolane, mâchefer, laitier, etc.), plastifiants, hydrofuges, colorants. They can also include one or more of the following products: natural or crushed aggregates (sand, gravel, pozzolan, clinker, slag, etc.), plasticizers, water repellents, dyes.

On donne ci-après des exemples de proportions des matériaux entrant dans la composition des mélanges utilisables pour la mise en oeuvre du procédé de l'invention.  Examples of the proportions of the materials used in the composition of the mixtures which can be used for carrying out the process of the invention are given below.

- A - Mélange à base de ciment
- ciment : 40 % à 60 X, en poids
- produit isolant : 20 % à 30 X, en poids
- agrégats : 10 %
- eau : quantité nécessaire au gâchage
normal des composants ci-dessus.- A - Cement-based mixture
- cement: 40% at 60 X, by weight
- insulating product: 20% at 30 X, by weight
- aggregates: 10%
- water: quantity required for mixing
normal of the above components.

- B - MéLange à base de plâtre
- plâtre : 25 X à 65 X, en poids
- produit isolant : 20 X à 30 %, en poids
- plastifiant et/ou colorant : 5 X
- eau : quantité nécessaire au
gâchage normal des
composants ci-dessus.- B - Plaster-based mixture
- plaster: 25 X to 65 X, by weight
- insulating product: 20 X to 30%, by weight
- plasticizer and / or dye: 5 X
- water: quantity required for
normal mixing
above components.

Lorsque le mélange utilisé est à base de plâtre, ce dernier peut, de manière intéressante, être constitué par un plâtre à staff ou par un plâtre assez dur. When the mixture used is based on plaster, the latter can, advantageously, be constituted by a plaster with staff or by a fairly hard plaster.

Le gâchis ou mortier 5' préparé de la manière ci-dessus est ensuite coulé à l'intérieur du moule 1 dans lequel il peut être ensuite tassé à l'aide de matériels et procédés appropriés connus en soi agissant par damage, ou par secousses, ou par vibrations, etc. The waste or mortar 5 'prepared in the above manner is then poured into the interior of the mold 1 in which it can then be compacted using suitable materials and methods known per se, acting by tamping, or by shaking, or by vibrations, etc.

Lorsque le degré de durcissement est suffisant, on procède au démoulage de la pierre artificielle brute 5 moulée, et celle-ci est ensuite séchée, naturellement ou à l'aide d'un appareil ou d'une installation de séchage appropriée. When the degree of hardening is sufficient, the molded raw artificial stone 5 is removed from the mold, and this is then dried, naturally or with the aid of a suitable drying apparatus or installation.

Cette pierre brute 5 comporte un parement 6 dont le grain est identique ou comparable à celui de la pierre naturelle ou de la pierre artificielle 3 utilisée comme modèle pour la fabrication du moule
Après séchage, le parement 6 de la pierre moulée 5 est teinté, par exemple par pulvérisation ou vaporisation d'au moins un produit de coloration appliqué à l'aide d'un appareil de pulvérisation adéquat (pistolet à plusieurs buses, par exemple) dont on a seulement représenté une buse de projection 7 à la figure 5. De manière très avantageuse, on applique successivement, sur le parement ou surface apparente de la pierre moulée, deux ou plus de deux substances colorantes de couleurs différentes.Les produits liquides de coloration pulvérisés peuvent être constitués par des peintures naturelles ou synthétiques telles que peintures acryliques, vinyliques ou autres ; dans le cas de fabrication de pierres calcaires fossilisées du genre dénommé "pierre du Gard", les produits de coloration peuvent être des peintures à base d'ocres naturels ou artificiels.This rough stone 5 has a facing 6 whose grain is identical or comparable to that of natural stone or artificial stone 3 used as a model for the manufacture of the mold.
After drying, the facing 6 of the molded stone 5 is tinted, for example by spraying or spraying with at least one coloring product applied using a suitable spraying device (spray gun with several nozzles, for example), of which only a projection nozzle 7 has been shown in FIG. 5. In a very advantageous manner, two or more of two coloring substances of different colors are successively applied to the facing or visible surface of the molded stone. Liquid coloring products sprayed can consist of natural or synthetic paints such as acrylic, vinyl or other paints; in the case of manufacture of fossilized limestone of the genus called "Gard stone", the coloring products can be paints based on natural or artificial ochres.

Après séchage de la substance colorante ainsi déposée, le parement teinté 6 est gratté superficiellement à l'aide d'un appareil ou d'un instrument approprié tel qu'une brosse métallique 8, ou un grattoir par exemple constitué par une spatule bien aiguisée. After the coloring substance thus deposited has dried, the tinted facing 6 is surface scraped using a suitable device or instrument such as a wire brush 8, or a scraper, for example constituted by a well sharpened spatula.

A la suite de ce grattage, le parement 6 présente un aspect identique ou quasi identique à celui de la pierre naturelle ayant servi de modèle pour la préparation du moule. Following this scraping, the facing 6 has an identical or almost identical appearance to that of natural stone having served as a model for the preparation of the mold.

La pierre artificielle obtenue de la manière indiquée ci-dessus peut avantageusement faire l'objet d'un traitement terminal de surface au moyen d'un produit ignifuge et/ou hydrofuge appliqué sur le parement 6 ou sur la totalité de la pierre par vaporisation ou par trempage. La face postérieure de La pierre peut, en outre, faire l'objet d'un traitement spécifique anti-humidité.  The artificial stone obtained in the manner indicated above can advantageously be subjected to a terminal surface treatment by means of a fire-retardant and / or water-repellent product applied to the facing 6 or to the whole of the stone by spraying or by soaking. The back of the stone can also be subject to a specific anti-humidity treatment.
