Definitions
- the present invention essentially relates to a process for manufacturing composite building elements, as well as an installation for implementing this process.
- Building blocks or concrete blocks made up of two layers or strata made of different materials have already been proposed in the building, and which are manufactured with a mold into which two materials of different compositions are successively introduced so as to obtain, after demolding, a block to two layers of different materials.
- German publication DE-A7-2 900 939 there is described a process for molding concrete blocks which consists in introducing into a mold two successive layers of material and then depositing above these two layers , that is to say above the molded block, a plate, after which the mold is subjected to a rotation of 180 ° so that the plate constitutes a support for the molded block which can thus be transported.
- the molding of the two layers or strata forming the block is carried out in a single step, that is to say by simply filling the mold with a first material and then with a second material.
- a separate treatment or molding of the two layers of the block is not carried out here, so that the latter, once molded and finished, does not have the required qualities of homogeneity and resistance.
- the object of the present invention is therefore to remedy these drawbacks by proposing a method and an installation which allow a rational, rapid and inexpensive manufacture of composite blocks with several layers, which exhibit remarkable homogeneity and resistance and which can be used for the construction of any buildings or works.
- the subject of the invention is a process for manufacturing composite construction elements forming for example parallelepipedic blocks or concrete blocks and of the type consisting in filling at least one mold with at least two materials of different compositions successively introduced into this mold. so as to obtain, after demolding, a block with two layers or layers of different materials, characterized in that before introducing a first material into the mold, a plate is placed across and inside the molding space or the like onto which this material falls so as to mold a layer of the block between this plate and the open upper part of the mold, then said plate is retracted from the interior molding space to cause said layer to descend by gravity in the bottom of the mold, after which another material is introduced into the remaining space of the mold to form another molded layer between the upper part of the first re stratum and mold.
- the method of the invention makes it possible to perfectly master the manufacture of the block by separate molding, in a way, of the various layers of the block in the same mold, so that in total, the finished block will always excellent and invariable qualities from one block to another, which was not the case with the methods of the prior art.
- the invention also relates to an installation for implementing the above method and of the type comprising at least one mold capable of receiving a plate or the like and which is associated with means for filling said mold with different materials, characterized in that that said plate is arranged between the upper part and the bottom of the mold to form a removable transverse partition in the interior space of said mold.
- a light is provided in at least one of the side walls of the mold to allow the guide and the sliding of the aforementioned plate.
- an installation according to the invention for manufacturing composite building blocks, essentially comprises a tray or table 1 equipped with a plurality of molds such as 2, whose open upper part 3 is flush with the table 1.
- the molds 2 can be an integral part of the table 1 or else constitute removable elements embedded in the openings provided in said table 1.
- the molds 2 have a generally substantially parallelepiped shape, but could very well have any other form without departing from the scope of the invention.
- Each mold 2 is equipped with a plate or the like 4 arranged transversely in the interior space of the mold 2, as seen in FIG. 1.
- the plate 4 can be actuated by any suitable means, such as for example a double-acting cylinder 5 of which the body has been shown at 6 and at 7 the rod connected at 8 to the plate 4, so that the latter can operate somewhat in the manner of a drawer capable of producing or not a transverse partition inside the mold 2.
- a light 9 allowing the guide and the sliding of the plate 4.
- the mold 2 has a removable bottom constituted by a support 10 allowing the evacuation of the building blocks after molding, as will be explained later.
- a container or container 11, 12 is provided on the table 1, and on either side of the opening 3 of the mold 2, a container or container 11, 12 is provided.
- the containers 11, 12 each contain a different material based on concrete and can slide by their bottoms 11a, 12a on table 1, as can be understood with reference to FIG. 1.
- These bottom walls 11a and 12a comprise respectively, and as best seen in FIG. 2, an opening 13,14 whose dimensions correspond substantially to the open upper part 3 of the mold 2.
- Each container 11, 12 can be actuated by a double-acting cylinder 15 which thus allows either to push the containers above the open upper part 3 of the mold 2, or to move them away from the part 3 of the mold, and this in sliding on the table 1, as will be explained later in detail about the operation.
- a press arranged above the table 1 and in line with the filling opening 3 of the molds 2, said press making it possible to press the materials contained in the mold 2 at the end of the molding operation .
- the tanks 11 and 12 are supplied by suitable means and not shown (hopper for example) with different construction materials.
- one of the tanks, for example tank 11 may contain traditional concrete
- the other tank 12 may contain a specific concrete, for example concrete lightened by suitable loads and such as for example expanded clay, glass beads or the like.
- the drawer or the plate 4 of the mold 2 is placed across the said mold using the jack 5, as can be seen in FIG. 1.
- the tank 11 is pushed by the jack 15 above the opening 3 of the mold, so that its content pours out through the opening 13 to fall on the plate or drawer 4 which, in this case, constitutes a bottom .
- the filling of the part 2a of the mold 2 can be carried out up to the level of its upper part 3, and, in doing so, the tray 11 is made to move back and forth using the jack 15 so as to level the concrete flush with the surface of the table 1.

- the container 11 is removed and takes the position visible in FIG. 1 so as to be filled up again, and, by means of the jack 5, the drawer is opened by removing the plate 4, which causes gravity to descend into the part of bottom 2b of the mold, the molded concrete which was originally in the part 2a, and which will form the lower stratum 32 of the block 30. It may still be useful at this stage to vibrate the mold 2 again to promote compaction in mold base. Then, the other tray 12 is brought above the mold and the same operations as those described above with respect to the tray 11, are carried out. In short, the material contained in the container 12 pours into the remaining molding space 2a, and this material is leveled back and forth from the container 12 on the table 1, so as to produce the upper layer 31 of the block 30.
- the press 22 is then actuated to compact the two layers filling the mold 2, and this possibly using the vibrating device 16.
- the press 22 is then raised and, for demolding, or lifts the table 1 using the jacks 17, or the support 10 is lowered using the jacks 19, or else the lifting movements and d aforementioned lowering.
- the composite blocks 30 with two layers according to the example considered are placed on the support 10 which constitutes a sort of removable base for the mold 2, and the blocks 30 are evacuated to a storage place or directly to steaming.
- a new support 10 is placed under the row of molds 2 so as to manufacture, as explained above, a new series of blocks.
- the method of the invention makes it possible to produce blocks with more than two layers, without departing from the scope of the invention.
- the control of the jacks 15, of the jacks 17 and 19, and even of the jack 6 can be automatic, all these jacks being able to be synchronized so that the installation according to the invention can operate automatically.
- the press 22 can be controlled by any suitable means and the design, shape and dimensions of tanks 11 and 12 and of the mold 2 can be any without departing from the scope of the invention. It is therefore possible to manufacture, by the process and installation of the invention, composite building blocks with several layers, at a high rate, a low production cost and a constant quality of the finished products.

Abstract
Description
La présente invention a essentiellement pour objet un procédé de fabrication d'éléments de construction composites, ainsi qu'une installation pour la mise en oeuvre de ce procédé.The present invention essentially relates to a process for manufacturing composite building elements, as well as an installation for implementing this process.
On a déjà proposé dans le bâtiment des blocs de construction ou parpaings constitués de deux couches ou strates en des matériaux différents, et qui sont fabriqués avec un moule dans lequel on introduit successivement deux matériaux de compositions différentes de façon à obtenir après démoulage, un bloc à deux couches de matériaux différents.Building blocks or concrete blocks made up of two layers or strata made of different materials have already been proposed in the building, and which are manufactured with a mold into which two materials of different compositions are successively introduced so as to obtain, after demolding, a block to two layers of different materials.
Toutefois les installations et procédés proposés jusqu'à présent pour fabriquer de tels blocs de construction demeuraient artisanaux ou compliqués et donc coûteux. De plus, les qualités de ces blocs de construction étaient souvent variables d'un bloc à l'autre, ce qui, comme on le comprend, est évidemment préjudiciable à la qualité de la construction que l'on réalise avec de tels blocs.However, the installations and processes proposed until now for manufacturing such building blocks remained artisanal or complicated and therefore costly. In addition, the qualities of these building blocks were often variable from one block to another, which, as we understand, is obviously detrimental to the quality of construction that is carried out with such blocks.
C'est ainsi que dans la publication allemande DE-A7-2 900 939, il est décrit un procédé pour mouler des blocs de béton qui consiste à introduire dans un moule deux couches successives de matériaux puis à déposer au-dessus de ces deux couches, c'est-à-dire au-dessus du bloc moulé, une plaque, ce après quoi on fait subir au moule une rotation de 180° de sorte que la plaque constitue un support pour le bloc moulé qui peut ainsi être transporté.Thus, in the German publication DE-A7-2 900 939, there is described a process for molding concrete blocks which consists in introducing into a mold two successive layers of material and then depositing above these two layers , that is to say above the molded block, a plate, after which the mold is subjected to a rotation of 180 ° so that the plate constitutes a support for the molded block which can thus be transported.
Mais, selon ce procédé, le moulage des deux couches ou strates formant le bloc est effectué en un seul temps, c'est-à-dire en remplissant tout simplement le moule avec un premier matériau puis avec un deuxième matériau. Autrement dit, on n'effectue pas ici un traitement ou un moulage séparé des deux strates du bloc, de sorte que celui-ci, une fois moulé et fini, ne présente pas les qualités d'homogénéité et de résistance requises.However, according to this method, the molding of the two layers or strata forming the block is carried out in a single step, that is to say by simply filling the mold with a first material and then with a second material. In other words, a separate treatment or molding of the two layers of the block is not carried out here, so that the latter, once molded and finished, does not have the required qualities of homogeneity and resistance.
Aussi la présente invention a pour but de remédier à ces inconvénients en proposant un procédé et une installation qui permettent une fabrication rationnelle, rapide et peu coûteuse de blocs composites à plusieurs strates, qui présentent une homogénéité et une résistance remarquables et qui peuvent être utilisés pour la construction de bâtiments ou d'ouvrages quelconques.The object of the present invention is therefore to remedy these drawbacks by proposing a method and an installation which allow a rational, rapid and inexpensive manufacture of composite blocks with several layers, which exhibit remarkable homogeneity and resistance and which can be used for the construction of any buildings or works.
A cet effet, l'invention a pour objet un procédé de fabrication d'éléments de construction composites formant par exemple blocs parallélépipèdiques ou parpaings et du type consistant à remplir au moins un moule avec un moins deux matériaux de compositions différentes introduits successivement dans ce moule de façon à obtenir après démoulage un bloc à deux couches ou strates de matériaux différents, caractérisé en ce qu'avant d'introduire un premier matériau dans le moule, on dispose en travers et à l'intérieur de l'espace de moulage une plaque ou analogue sur laquelle tombe ce matériau pour ainsi réaliser le moulage d'une strate du bloc entre cette plaque et la partie supérieure ouverte du moule, puis on escamote ladite plaque de l'espace intérieur de moulage pour provoquer la descente par gravité de ladite strate dans le fond du moule, ce après quoi on introduit un autre matériau dans l'espace restant du moule pour former une autre strate moulée entre la partie supérieure de la première strate et du moule.To this end, the subject of the invention is a process for manufacturing composite construction elements forming for example parallelepipedic blocks or concrete blocks and of the type consisting in filling at least one mold with at least two materials of different compositions successively introduced into this mold. so as to obtain, after demolding, a block with two layers or layers of different materials, characterized in that before introducing a first material into the mold, a plate is placed across and inside the molding space or the like onto which this material falls so as to mold a layer of the block between this plate and the open upper part of the mold, then said plate is retracted from the interior molding space to cause said layer to descend by gravity in the bottom of the mold, after which another material is introduced into the remaining space of the mold to form another molded layer between the upper part of the first re stratum and mold.
On comprend donc déjà que le procédé de l'invention permet de maîtriser parfaitement la fabrication du bloc par moulage séparé, en quelque sorte, des diverses couches du bloc dans un même moule, de sorte qu'au total, le bloc fini, présentera toujours des qualités excellentes et invariables d'un bloc à l'autre, ce qui n'était pas le cas avec les procédés de l'art antérieur.It is therefore already understood that the method of the invention makes it possible to perfectly master the manufacture of the block by separate molding, in a way, of the various layers of the block in the same mold, so that in total, the finished block will always excellent and invariable qualities from one block to another, which was not the case with the methods of the prior art.
L'invention vise également une installation pour la mise en oeuvre du procédé ci-dessus et du type comprenant au moins un moule susceptible de recevoir une plaque ou analogue et auquel sont associés des moyens de remplissage dudit moule avec des matériaux différents, caractérisée en ce que ladite plaque est agencée entre la partie supérieure et le fond du moule pour former une cloison transversale amovible dans l'espace intérieur dudit moule.The invention also relates to an installation for implementing the above method and of the type comprising at least one mold capable of receiving a plate or the like and which is associated with means for filling said mold with different materials, characterized in that that said plate is arranged between the upper part and the bottom of the mold to form a removable transverse partition in the interior space of said mold.
Suivant une autre caractéristique de cette installation, une lumière est ménagée dans au moins l'une des parois latérales du moule pour permettre le guidage et le coulissement de la plaque précitée.According to another characteristic of this installation, a light is provided in at least one of the side walls of the mold to allow the guide and the sliding of the aforementioned plate.
D'autres caractéristiques et avantages de l'invention apparaîtront mieux dans la description détaillée qui suit et se réfère aux dessins annexés, donnés uniquement à titre d'exemple, et dans lesquels:
- La figure 1 est une vue schématique en élévation d'une installation de fabrication d'éléments de construction composites, conforme à l'invention.
- La figure 2 est une vue schématique et de dessus de l'installation montrée sur la figure 1; et
- La figure 3 illustre en perspective un bloc de construction composite fabriqué à l'aide de cette installation.
- Figure 1 is a schematic elevational view of an installation for manufacturing composite building elements, according to the invention.
- Figure 2 is a schematic top view of the installation shown in Figure 1; and
- Figure 3 illustrates in perspective a composite building block manufactured using this installation.
Suivant un exemple de réalisation, et en se reportant aux figures 1 et 2, une installation conforme à l'invention, pour fabriquer des blocs de construction composites, comprend essentiellement un plateau ou table 1 équipé d'une pluralité de moules tels que 2, dont la partie supérieure ouverte 3 affleure avec la table 1. Les moules 2 peuvent faire partie intégrante de la table 1 ou bien constituer des éléments amovibles encastrés dans des ouvertures prévues dans ladite table 1. Les moules 2 présentent une forme générale sensiblement parallèlépipédique, mais pourraient très bien présenter toute autre forme sans sortir du cadre de l'invention.According to an exemplary embodiment, and with reference to FIGS. 1 and 2, an installation according to the invention, for manufacturing composite building blocks, essentially comprises a tray or table 1 equipped with a plurality of molds such as 2, whose open
Chaque moule 2 est équipé d'une plaque ou analogue 4 agencée transversalement dans l'espace intérieur du moule 2, comme on le voit sur la figure 1. La plaque 4 peut être actionnée par tout moyen approprié, tel que par exemple un vérin à double effet 5 dont on a montré en 6 le corps et en 7 la tige reliée en 8 à la plaque 4, de façon que cette dernière puisse fonctionner un peu à la manière d'un tiroir susceptible de réaliser ou non un cloison transversale à l'intérieur du moule 2. A cet effet, on prévoir évidemment dans au moins l'une des parois latérales du moule 2 une lumière 9 permettant le guidage et le coulissement de la plaque 4.Each
Suivant l'exemple représenté, le moule 2 comporte un fond amovible constitué par un support 10 permettant l'évacuation des blocs de construction après moulage, comme on l'expliquera ultérieurement.According to the example shown, the
Sur la table 1, et de part et d'autre de l'ouverture 3 du moule 2, on prévoit un récipient ou bac 11, 12. Les bacs 11, 12 contiennent chacun un matériau différent à base de béton et peuvent coulisser par leurs fonds 11a, 12a sur la table 1, comme on le comprend en se reportant à la figure 1. Ces parois de fond 11a et 12a comportent respectivement, et comme on le voit mieux sur la figure 2, une ouverture 13,14 dont les dimensions correspondent sensiblement à la partie supérieure ouverte 3 du moule 2.On the table 1, and on either side of the opening 3 of the
Chaque récipient 11, 12 peut être actionné par un vérin à double effet 15 qui permet ainsi soit de pousser les récipients au-dessus de la partie supérieure ouverte 3 du moule 2, soit de les éloigner de la partie 3 du moule, et cela en glissant sur la table 1, comme on l'expliquera plus loin en détail à propos du fonctionnement.Each
On a montré schématiquement en 16 un dispositif du type connu en soi et qui est associé au moule 2 pour lui faire subir des vibrations susceptibles de tasser les matériaux contenus dans ledit moule.There is shown schematically at 16 a device of the type known per se and which is associated with the
Sous la table 1 sont prévus des vérins à double effet 17 dont la tige 18 est fixée en 18a par tout moyen approprié, sur le dessous de ladite table 1. Ces vérins 17 permettent le soulèvement de la table 1 et donc des moules 2 pour réaliser le démoulage des blocs qui ainsi reposent sur le support 10, lequel peytégalement être équipé de vérins 19 dont la tige 20 est fixée en 21 sur le dessous du support 10. Ainsi, pour effectuer le démoulage, on peut soit soulever la table 1 à l'aide des vérins 17, soit abaisser le support 10 à l'aide des vérins 19, ou bien encore agir simultanément sur les deux groupes de vérins 17 et 19.Under the table 1 are provided double-acting
On a montré schématiquement en 22 une presse disposée au-dessus de la table 1 et au droit de l'ouverture de remplissage 3 des moules 2, ladite presse permettant de presser les matériaux contenus dans le moule 2 en fin de l'opération de moulage.There is shown schematically at 22 a press arranged above the table 1 and in line with the filling opening 3 of the
On expliquera maintenant le fonctionnement de l'installation ci-dessus décrite et qui permet d'obtenir des blocs de construction composites à deux ou plusieurs strates, tels que repérés en 31 et 32 sur la figure 3.We will now explain the operation of the installation described above and which makes it possible to obtain composite building blocks with two or more strata, as identified at 31 and 32 in FIG. 3.
On dira tout d'abord que les bacs 11 et 12 sont alimentés par des moyens appropriés et non représentés (trémie par exemple) en des matériaux de construction différents. C'est ainsi que l'un des bacs, par exemple le bac 11, pourra contenir du béton traditionnel, et que l'autre bac 12 pourra contenir un béton particulier, par exemple un béton allégé par des charges appropriées et telles que par exemple argile expansée, billes de verre ou analogues. Les diverses opérations conduisant à la fabrication du bloc composites 30 à deux strates 31 et 32, visible sur la figure 3, sont alors les suivantes.It will first be said that the
Le tiroir ou la plaque 4 du moule 2 est placé en travers dudit moule à l'aide du vérin 5, comme on le voit bien sur la figure 1.The drawer or the
Le bac 11 est poussé par la vérin 15 au-dessus de l'ouverture 3 du moule, de sortie que son contenu se déverse par l'ouverture 13 pour tomber sur la plaque ou tiroir 4 qui, en l'occurence, constitue un fond. Ainsi, le remplissage de la partie 2a du moule 2 peut s'effectuer jusqu'au niveau de sa partie supérieure 3, et, ce faisant, on imprime au bac 11 un mouvement de va-et-vient à l'aide du vérin 15 de façon à araser le béton affleurant avec la surface de la table 1. On ajoutera encore ici que le béton dans le compartiment 2a du moule peut être, à ce stade, tassé à l'aide du dispositif vibrant 16.The tank 11 is pushed by the
Le bac 11 est retiré et prend la position visible sur la figure 1 de façon à être du nouveau rempli, et, au moyen du vérin 5, on ouvre le tiroir en retirant la plaque 4, ce qui fait descendre par gravité dans la partie de fond 2b du moule, le béton moulé qui se trouvait primitivement dans la partie 2a, et qui formera la strate inférieure 32 du bloc 30. Il.peut encore être utile à ce stade de faire vibrer à nouveau le moule 2 pour favoriser le tassement en fond de moule. Ensuite, on amène l'autre bac 12 au-dessus du moule et les mêmes opérations que celles décrites précédemment à propos du bac 11, sont effectuées. En bref, le matériau contenu dans le bac 12 se déverse dans l'espàce restant de moulage 2a, et ce matériau est arasé par va-et-vient du bac 12 sur la table 1, de façon à réaliser la strate supérieure 31 du bloc 30.The container 11 is removed and takes the position visible in FIG. 1 so as to be filled up again, and, by means of the jack 5, the drawer is opened by removing the
Le bac 12 étant ramené à son point de départ, on actionne alors la presse 22 pour tasser les deux strates remplissant le moule 2, et cela en utilisant éventuellement le dispositif vibrant 16.The
La presse 22 est ensuite relevée et, pour le démoulage, ou soulève la table 1 à l'aide des vérins 17, ou bien on abaisse le support 10 à l'aide des vérins 19, ou encore on combine les mouvements de soulèvement et d'abaissement précités. Ceci étant fait, les blocs composites 30 à deux strates suivant l'exemple considéré se trouvent déposés sur le support 10 qui constitue en quelque sorte un fond amovible pour le moule 2, et on évacue les blocs 30 vers un lieu de stockage ou directement vers l'étuvage. Puis, on place un nouveau support 10 sous la rangée de moules 2 de manière à fabriquer comme expliqué ci-dessus une nouvelle série de blocs.The press 22 is then raised and, for demolding, or lifts the table 1 using the
Bien entendu, le procédé de l'invention permet de réaliser des blocs à plus de deux strates, sans sortir du cadre de l'invention. Egalement, la commande des vérins 15, des vérins 17 et 19, et même du vérin 6 peut être automatique, tous ces vérins pouvant être synchronisés pour que l'installation conforme à l'invention puisse fonctionner de manière automatique. On pourrait aussi imaginer pour certains éléments de l'installation des systèmes d'actionnement autres que des vérins à double effet. Enfin, la presse 22 peut être commandée par tout moyen approprié et la conception, la forme et les dimensions de bacs 11 et 12 et du moule 2 peuvent être quelconques sans sortir du cadre de l'invention. On peut donc fabriquer par le procédé et l'installation de l'invention des blocs de construction composites à plusieurs strates, suivant une cadence élevée, un faible coût de production et une qualité constante des produits finis.Of course, the method of the invention makes it possible to produce blocks with more than two layers, without departing from the scope of the invention. Also, the control of the
