Description

Le brevet suisse No ( demande No 01'654/89-0 ) décrit un panneau de construction constitué pur une brique creuse, en terre cuite, et par un revêtement en plâtre, et deux variantes de ce panneau dans lesquelles les cavités de la brique sont remplies d'une mousse de polyuréthane, respectivement de plâtre.The Swiss patent No (application No 01'654 / 89-0) describes a construction panel made up of a hollow brick, in terracotta, and by a plaster covering, and two variants of this panel in which the cavities of the brick are filled with polyurethane foam, respectively plaster.

La présente invention a pour objet un procédé de fabrication d'un tel panneau, une installation pour la mise en oeuvre de ce procédé, et un panneau de construction obtenu par cette installation.The present invention relates to a method for manufacturing such a panel, an installation for implementing this method, and a construction panel obtained by this installation.

Le procédé selon l'invention est caractérisé par le fait que l'on part d'une brique creuse, en terre cuite, que l'on place cette brique dans un moule dans lequel on coule du plâtre de manière à former ledit revêtement, que l'on démoule le panneau ainsi obtenu alors que le plâtre est encore humide, et que l'on introduit ce panneau dans un four jusqu'à séchage complet du revêtement.The method according to the invention is characterized in that one starts from a hollow brick, terracotta, that one places this brick in a mold into which plaster is poured so as to form said coating, that the panel thus obtained is removed from the mold while the plaster is still wet, and this panel is introduced into an oven until the coating has completely dried.

L'installation selon l'invention, qui permet de fabriquer en série de tels panneaux, est caractérisée par le fait qu'elle comprend une chaîne de fabrication comportant un poste de moulage où du plâtre est coulé autour des briques pour former ledit revêtement et par un four dans lequel ce revêtement est séché par de l'air chaud.The installation according to the invention, which allows mass production of such panels, is characterized in that it comprises a production line comprising a molding station where plaster is poured around the bricks to form said coating and by an oven in which this coating is dried by hot air.

Le dessin ci-annexé représente, schématiquement et à titre d'exemple, une forme d'exécution entièrement automatique d'une installation selon l'invention ( figure 1 ) et un panneau de construction fabriqué par cette installation ( figure 2 ).The attached drawing shows, schematically and by way of example, a fully automatic embodiment of an installation according to the invention (Figure 1) and a construction panel manufactured by this installation (Figure 2).

Ce panneau est constitué ( figure 2 ) par une brique 10, en terre cuite, comportant huit cavités longitudinales 11 et par un revêtement extérieur 12, en plâtre, présentant des rainures 13 et des nervures 14 pour l'assemblage.This panel is constituted (FIG. 2) by a brick 10, made of terracotta, comprising eight longitudinal cavities 11 and by an external covering 12, made of plaster, having grooves 13 and ribs 14 for assembly.

L'installation représentée à la figure 1 fabrique automatiquement, en série, des panneaux de ce type, en partant de briques 10 chargées sur des palettes qui sont amenées par un chariot-élévateur 15 à l'entrée d'une chaine de fabrication. Chaque palette porte un empilage de trois paquets 16 de dix-sept briques 10 posées de champ ( Vue A ).The installation shown in FIG. 1 automatically manufactures panels of this type in series, starting from bricks 10 loaded on pallets which are brought by a forklift truck 15 to the entrance to a production line. Each pallet carries a stack of three packages 16 of seventeen bricks 10 placed in the field (View A).

Les palettes sont placées l'une après l'autre sur deux courroies crantées 17 qui les convoient jusqu'à un poste 18 où les empilages sont soulevés et immobilisés par des moyens non représentés et les paquets 16 qui les composent replacés individuellement sur les courroies 17 en aval de ce poste.The pallets are placed one after the other on two notched belts 17 which convey them to a station 18 where the stacks are lifted and immobilized by means not shown and the packages 16 which compose them replaced individually on the belts 17 downstream of this post.

Les paquets 16 arrivent alors l'un derrière l'autre jusqu'à un poste 19 où les briques 10 sont couchées individuellement l'une après l'autre.The packages 16 then arrive one behind the other to a station 19 where the bricks 10 are laid individually one after the other.

Les courroies 17 convoient ensuite les briques 10 posées à plat jusqu'à un poste 20 où elles sont lavées, puis à un poste 21 où leurs cavités 11 sont bouchées par des feuilles de carton.The belts 17 then convey the bricks 10 laid flat to a station 20 where they are washed, then to a station 21 where their cavities 11 are plugged with sheets of cardboard.

Ces briques 10 arrivent ensuite à un poste 22 où elles sont remises debout avant d'être prises en charge, pur paire, pur un dispositif 23 qui les transporte à un poste de moulage 24.These bricks 10 then arrive at a station 22 where they are put back upright before being taken over, pure pair, for a device 23 which transports them to a molding station 24.

Ce poste 24 est constitué par un carrousel 25 comportant un certain nombre de moules 26 disposés diamétralement, par paire, dans lesquelles les briques 10 sont introduites durant des arrêts de la rotation intermittente du carrousel. Une tuyère 27, alimentée par deux réservoirs 28 et 29 contenant respectivement du plâtre et un adjuvant sécatif, injecte alors du plâtre additionné d'une certaine quantité d'adjuvant, dans les moules 26 pour former les revêtements 12.This station 24 is constituted by a carousel 25 comprising a number of molds 26 arranged diametrically, in pairs, into which the bricks 10 are introduced during stops of the intermittent rotation of the carousel. A nozzle 27, fed by two reservoirs 28 and 29 respectively containing plaster and a secative adjuvant, then injects plaster with a certain amount of adjuvant into the molds 26 to form the coatings 12.

Les fonds des moules 26 et des rabats mobiles non représentés au dessin façonnent les rainures 13 et les nervures 14, tandi qu'un râcloir 30 évacue l'excédent de plâtre.The bottoms of the molds 26 and of the movable flaps not shown in the drawing shape the grooves 13 and the ribs 14, while a scraper 30 removes the excess plaster.

Au terme d'une révolution du carrousel 25, un dispositif 31 démoule, durant un arrêt du mouvement, les panneaux partiellement séchés et les pose sur une plateforme 32 où ils sont pris en charge par des moyens non représentés qui les groupe par quatorze pièces espacées les unes des autres.At the end of a revolution of the carousel 25, a device 31 demoulds, during a stop of the movement, the partially dried panels and places them on a platform 32 where they are supported by means not shown which group them by fourteen spaced parts each other.

Les groupes ainsi constitués sont alors transportés , l'un après l'autre par un dispositif 33, qui maintient les espaces entre les panneaux, respectivement sur les trois tapis roulants 34 d'un four de séchage continu 35.The groups thus formed are then transported, one after the other by a device 33, which maintains the spaces between the panels, respectively on the three conveyor belts 34 of a continuous drying oven 35.

Une fois chargés, les trois tapis 34 sont mis en route, et les panneaux, toujours espacés, s'engagent dans le tunnel 36 du four 35 où ils sont soumis à des courants d'air chaud à température réglable pulsés pur des circulateurs 35 ' .Once loaded, the three belts 34 are started up, and the panels, always spaced, engage in the tunnel 36 of the oven 35 where they are subjected to currents of hot air at adjustable temperature pulsed pure by the circulators 35 ' .

A la sortie du tunnel 36, un dispositif 37 serre les uns contre les autres les panneaux séchés 10 de chaque groupe , de manière à former trois paquets 38 qu'il transporte l'un après l'autre sur une plateforme 39 en les faisant pivoter de 90o et en les empilant sur une palette.At the exit of the tunnel 36, a device 37 clamps against each other the dried panels 10 of each group, so as to form three packages 38 which it transports one after the other on a platform 39 by rotating them 90 o and stacking them on a pallet.

La palette, avec son chargement , est ensuite dirigée vers deux machines 40 et 41 où l'ensemble est lié et enveloppé dans une housse de protection.The pallet, with its load, is then sent to two machines 40 and 41 where the assembly is linked and wrapped in a protective cover.

Les palettes successives peuvent alors être prises en charge par un chariot élévateur 42 pour être directement chargées sur un camion ou entreposées dans un lieu de stockage.The successive pallets can then be taken care of by a forklift truck 42 to be directly loaded on a truck or stored in a storage place.

Cette installation permet de fabriquer également des panneaux de construction du type représenté à la figure 2 dans lesquels les cavités 11 sont remplies de plâtre. Dans ce cas, il suffira de supprimer ou de mettre hors-service le poste 21 de sorte que les cavités ne seront pas bouchées et que le plâtre injecté dans les moules 26 pourra pénétrer dans ces cavités et les remplir. Dans une variante de l'installation représentée et décrite ci-dessus permettant d'obtenir des panneaux dans lesquels les cavités 11 sont remplies d'une mousse de matière plastique destinée à accroître ses qualités isolantes, pur exemple une mousse de polyuréthane, on remplacera le poste 21 par un poste où cette mousse, ou un autre produit, sera injecté dans les cavités 11 avant d'arriver au poste de moulage 24.This installation also makes it possible to manufacture construction panels of the type shown in FIG. 2 in which the cavities 11 are filled with plaster. In this case, it will suffice to remove or put out of service the station 21 so that the cavities will not be plugged and the plaster injected into the molds 26 may enter these cavities and fill them. In a variant of the installation shown and described above making it possible to obtain panels in which the cavities 11 are filled with a plastic foam intended to increase its insulating qualities, for example a polyurethane foam, the station 21 by a station where this foam, or another product, will be injected into the cavities 11 before arriving at the molding station 24.

Le procédé selon l'invention dans la mise en oeuvre duquel le plâtre est séché au moins partiellement dans un four permet d'obtenir des panneaux de construction du type décrit d'une qualité largement supérieure et dans un temps beaucoup plus court que ceux qui sont séchés à l'air libre.The method according to the invention in the implementation of which the plaster is dried at least partially in an oven makes it possible to obtain construction panels of the type described of a much higher quality and in a much shorter time than those which are air dried.
