Description

La présente invention concerne le domaine du bâtiment, en particulier les éléments de construction et notamment les hourdis et a pour objet un procédé de fabrication de hourdis autocoffrants et isolants.The present invention relates to the field of construction, in particular construction elements and in particular the slabs and relates to a method of manufacturing self-forming and insulating slabs.

L'invention a également pour objet un dispositif pour la mise en oeuvre de ce procédé ainsi que les hourdis obtenus.The invention also relates to a device for implementing this process as well as the slabs obtained.

Actuellement, il existe déjà des hourdis en matières synthétiques, très légers, destinés à former des coffrages isolants pour la réalisation de planchers.Currently, there are already slabs of synthetic materials, very light, intended to form insulating forms for the realization of floors.

Il existe également des hourdis en polystyrène autocoffrants et autoporteurs qui sont munis de raidisseurs en béton armé. Ces hourdis permettent généralement la réalisation d'un coffrage de planchers nécessitant un étaiement minimal, mais présentent, cependant, l'inconvénient d'être relativement lourds et de ne pas pouvoir pratiquement être manutentionnés par un opérateur seul. En outre, l'élément raidisseur en béton armé, qui est coulé dans une rainure longitudinale prévue à cet effet dans la face inférieure des hourdis, fait apparaître sur cette dernière une trace de couleur différente ne permettant pas de laisser la face inférieure du plancher fini ainsi obtenu sans un revêtement de finition.There are also self-supporting and self-supporting polystyrene slabs which are fitted with reinforced concrete stiffeners. These slabs generally allow the realization of a formwork of floors requiring minimal shoring, but have, however, the disadvantage of being relatively heavy and not being able to be practically handled by an operator alone. In addition, the reinforced concrete stiffening element, which is poured into a longitudinal groove provided for this purpose in the underside of the slabs, shows on the latter a trace of different color not allowing to leave the underside of the finished floor. thus obtained without a finishing coating.

Enfin, la réalisation des raidisseurs en béton armé nécessite un temps de séchage relativement long de ces raidisseurs, ce qui entraîne un stockage intermédiaire des hourdis ainsi obtenus relativement long et, en corollaire, nécessite des aires ou des halls de stockage importants.Finally, the production of reinforced concrete stiffeners requires a relatively long drying time for these stiffeners, which results in relatively long intermediate storage of the slabs thus obtained, and, as a corollary, requires large storage areas or halls.

La présente invention a pour but de pallier ces inconvénients.The present invention aims to overcome these drawbacks.

Elle a, en effet, pour objet un procédé de fabrication de hourdis autocoffrants et isolants constitués en matière synthétique moussée, en particulier en polystyrène expansé, caractérisé en ce qu'il consiste essentiellement à insérer, lors du moulage, au moins un profilé longitudinal dans la mousse en formation.It has, in fact, for its object a method of manufacturing self-forming and insulating slabs made of foamed synthetic material, in particular of expanded polystyrene, characterized in that it essentially consists in inserting, during molding, at least one longitudinal profile in foam in formation.

L'invention a également pour objet un dispositif pour la mise en oeuvre de ce procédé caractérisé en ce qu'il est essentiellement constitué par une machine de moulage en continu ou en discontinu, dont le moule est muni à son extrémité arrière d'au moins une ouverture étanche d'introduction d'au moins un profilé longitudinal, par un moyen d'introduction du ou des profilés dans le moule et, éventuellement, par un dispositif de réalisation en continu de profilés.The invention also relates to a device for implementing this method, characterized in that it essentially consists of a continuous or discontinuous molding machine, the mold of which is provided at its rear end with at least a sealed opening for the introduction of at least one longitudinal profile, by a means for introducing the profile or profiles into the mold and, optionally, by a device for continuously producing profiles.

L'invention a aussi pour objet les hourdis ainsi obtenus, qui sont caractérisés en ce qu'ils sont pourvus d'au moins un profilé longitudinal intégré dans leur masse.The invention also relates to the slabs thus obtained, which are characterized in that they are provided with at least one longitudinal section integrated in their mass.

L'invention sera mieux comprise grâce à la description ci-après, qui se rapporte à un mode de réalisation préféré, donné à titre d'exemple non limitatif, et expliqué avec référence aux dessins schématiques annexés, dans lesquels :

  • la figure 1 est une vue en coupe d'un hourdis conforme à l'invention ;
  • la figure 2 est une vue en plan représentant l'implantation du dispositif pour la mise en oeuvre du procédé conforme à l'invention, et
  • la figure 3 est une vue en élévation latérale, partiellement en coupe de la machine de moulage.
The invention will be better understood from the description below, which relates to a preferred embodiment, given by way of nonlimiting example, and explained with reference to the appended schematic drawings, in which:
  • Figure 1 is a sectional view of a slab according to the invention;
  • FIG. 2 is a plan view showing the installation of the device for implementing the method according to the invention, and
  • Figure 3 is a side elevational view, partially in section, of the molding machine.

Conformément à l'invention, et comme le montre plus particulièrement, à titre d'exemple, la figure 1 des dessins annexés, le procédé de fabrication de hourdis autocoffrants et isolants 1 constitués en matière synthétique moussée, en particulier en polystyrène expansé, consiste essentiellement à insérer, lors du moulage, au moins un profilé longitudinal 2 dans la mousse en formation.In accordance with the invention, and as shown more particularly, by way of example, FIG. 1 of the accompanying drawings, the method of manufacturing self-forming and insulating slabs 1 made of foamed synthetic material, in particular of expanded polystyrene, essentially consists to insert, during molding, at least one longitudinal section 2 in the foam in formation.

Le profilé longitudinal 2 est constitué, selon une caractéristique de l'invention, en une fine tôle métallique pliée.According to a characteristic of the invention, the longitudinal section 2 is made of a thin folded metal sheet.

Le profilé longitudinal 2 peut également être constitué, conformément à une variante de réalisation de l'invention, en une matière synthétique extrudée rigide telle que du PVC ou analogue.The longitudinal profile 2 can also be made, in accordance with an alternative embodiment of the invention, of a rigid extruded synthetic material such as PVC or the like.

L'invention a également pour objet un dispositif pour la mise en oeuvre de ce procédé, représenté particulièrement aux figures 2 et 3 et essentiellement constitué par une machine 3 de moulage en continu ou en discontinu, dont le moule 4 est muni à son extrémité arrière d'au moins une ouverture étanche 5 d'introduction d'au moins un profilé longitudinal 2, par un moyen 6 d'introduction du ou des profilés 2 dans le moule 4 et, éventuellement, par un dispositif 7 de réalisation en continu de profilés.The invention also relates to a device for implementing this process, shown particularly in Figures 2 and 3 and essentially consisting of a machine 3 for continuous or discontinuous molding, with which the mold 4 is provided at its rear end. at least one sealed opening 5 for introducing at least one longitudinal profile 2, by means 6 for introducing the profile (s) 2 into the mold 4 and, optionally, by a device 7 for continuously producing profiles .

Le moyen 6 d'introduction du ou des profilés 2 dans le moule 4 se présente avantageusement sous forme d'un chariot mobile 8 monté de manière coulissante, en sens longitudinal, sur le bâti de la machine de moulage 3 au moyen d'au moins un vérin de déplacement 9 et est pourvu, à son extrémité opposée à ladite machine 3, d'une traverse 10 de maintien du ou des profilés 2. Ce maintien des profilés 2 est assuré, soit par un ou plusieurs logements ménagés sur la traverse 10, soit par des pinces 11 ouvertes en sens longitudinal et actionnées par des vérins 12. Ainsi, au début du moulage de chaque hourdis un profilé 2 est placé dans le logement correspondant de la traverse 10 du moyen 6 ou est serré dans la pince 11 correspondante, puis poussé dans le moule d'une longueur correspondant à un cycle de moulage. Après expansion de la mousse, le tronçon moulé est poussé hors du moule du côté opposé au moyen 6, qui pousse simultanément le ou les profilés de rigidification dans le moule d'une longueur correspondant au nouveau tronçon à mouler. Ces opérations sont répétées jusqu'à obtention de la longueur de hourdis désirée, les profilés 2 présentant, dans un tel cas, une longueur égale à celle des hourdis à obtenir. Il est également possible, en particulier dans le cas d'utilisation de pinces 11, de réaliser un moulage en continu d'un hourdis unique, ce dernier étant débité à des longueurs désirées de hourdis individuels à la sortie de la machine de moulage 3, lors d'un cycle de moulage, par l'intermédiaire d'une unité de sciage monté en aval de la machine 3 et non représentée.The means 6 for introducing the profile (s) 2 into the mold 4 is advantageously in the form of a mobile carriage 8 slidably mounted, in a longitudinal direction, on the frame of the molding machine 3 by means of at least a displacement cylinder 9 and is provided, at its end opposite to said machine 3, with a cross-member 10 for holding the profile (s) 2. This profile (2) is maintained either by one or more housings provided on the cross-member 10 , either by pliers 11 open in the longitudinal direction and actuated by jacks 12. Thus, at the start of the molding of each slab a profile 2 is placed in the corresponding housing of the cross member 10 of the means 6 or is clamped in the corresponding clamp 11 , then pushed into the mold of a length corresponding to a molding cycle. After expansion of the foam, the molded section is pushed out of the mold on the opposite side to the means 6, which simultaneously pushes the stiffening profile or profiles in the mold with a length corresponding to the new section to be molded. These operations are repeated until the desired length of slabs is obtained, the profiles 2 having, in such a case, a length equal to that of the slabs to be obtained. It is also possible, in particular in the case of use of pliers 11, to carry out a continuous molding of a single slab, the latter being cut to desired lengths of individual slabs at the outlet of the molding machine 3, during a cycle molding, by means of a sawing unit mounted downstream of the machine 3 and not shown.

Le dispositif 7 de réalisation en continu de profilés 2 peut se présenter, avantageusement, sous forme, soit d'une plieuse de tôle en continu ou en discontinu, soit d'une presse à injecter. Dans le premier cas, la plieuse de tôle peut être alimentée en continu par une fine bande de tôle et réaliser un pliage en continu de cette bande ou encore être alimentée par des sections de bandes de tôle correspondant à une longueur prédéterminée de profilés 2.The device 7 for continuously producing profiles 2 can advantageously be in the form of either a continuous or discontinuous sheet bending machine or an injection molding machine. In the first case, the sheet bending machine can be continuously fed by a thin strip of sheet metal and perform a continuous folding of this strip or even be fed by sections of sheet metal strips corresponding to a predetermined length of profiles 2.

Dans le cas de réalisation du dispositif 7 sous forme d'une presse à injecter, cette dernière délivre à la sortie de sa filière une bande profilée continue.In the case of embodiment of the device 7 in the form of an injection molding machine, the latter delivers at the outlet of its die a continuous profiled strip.

Conformément à une caractéristique de l'invention, le dispositif 7 peut être muni à la sortie des profilés 2 d'un dispositif 13 de débitage desdits profilés 2 à la longueur désirée.In accordance with a characteristic of the invention, the device 7 can be provided at the outlet of the profiles 2 with a device 13 for cutting up said profiles 2 to the desired length.

L'invention a aussi pour objet les hourdis ainsi obtenus qui sont caractérisés en ce qu'ils sont pourvus d'au moins un profilé longitudinal 2 intégré dans leur masse.The invention also relates to the slabs thus obtained which are characterized in that they are provided with at least one longitudinal section 2 integrated in their mass.

Le ou les profilés longitudinaux 2 intégrés dans la masse des hourdis 1 peuvent présenter une très faible épaisseur, qui, en pratique, n'est pas compatible avec une tenue au flambage desdits profilés 2 suivant leur section verticale, cette tenue étant assurée par la matière moussante formant la masse des hourdis 1, à savoir, généralement le polystyrène.The longitudinal section (s) 2 integrated in the mass of the slabs 1 may have a very small thickness, which, in practice, is not compatible with a buckling behavior of said sections 2 along their vertical section, this behavior being provided by the material foam forming the mass of the slabs 1, namely, generally polystyrene.

L'invention permet donc la réalisation de hourdis en polystyrène armé présentant un très faible poids unitaire et pouvant facilement être transportés et manipulés par une personne seule.The invention therefore allows the production of reinforced polystyrene slabs having a very low unit weight and which can easily be transported and handled by a single person.

En outre, les hourdis ainsi obtenus sont parfaitement autoportants et nécessitent de ce fait un étaiement minimal.In addition, the slabs thus obtained are perfectly self-supporting and therefore require shoring minimal.

Par ailleurs, du fait que les profilés 2 sont intégrés dans la masse des hourdis 1, ces derniers présentent un fini de leur face inférieure parfait, ce fini pouvant éventuellement être amélioré par la prévision de moulures, de sorte qu'un revêtement ultérieur de cette face devient inutile.Furthermore, owing to the fact that the profiles 2 are integrated into the mass of the slabs 1, the latter have a perfect finish on their underside, this finish possibly being able to be improved by providing moldings, so that a subsequent coating of this face becomes useless.

Enfin, le procédé conforme à l'invention permet une réalisation de hourdis en fonction de la demande, c'est-à-dire suivant la méthode de travail en juste-à-temps, de sorte que les stocks après fabrication peuvent être réduits à un minimum, ce qui entraîne un gain de productivité et une réduction du prix de revient.Finally, the method according to the invention allows for production of slabs according to demand, that is to say according to the just-in-time working method, so that the stocks after manufacture can be reduced to a minimum, which leads to a gain in productivity and a reduction in the cost price.

Bien entendu, l'invention n'est pas limitée au mode de réalisation décrit et représenté au dessin annexé. Des modifications restent possibles, notamment du point de vue de la constitution des divers éléments ou par substitution d'équivalents techniques, sans sortir pour autant du domaine de protection de l'invention.Of course, the invention is not limited to the embodiment described and shown in the accompanying drawing. Modifications remain possible, in particular from the point of view of the constitution of the various elements or by substitution of technical equivalents, without thereby departing from the scope of protection of the invention.
