Description

La présente invention concerne un nouveau type de mur destiné à la construction d'habitations dites "préfabriquées", et qui présente, par rapport aux murs déjà connus pour cette application, des avantages importants, sur le plan technique aussi bien que sur le plan économique. The present invention relates to a new type of wall intended for the construction of so-called "prefabricated" dwellings, and which presents, compared to the walls already known for this application, significant advantages, both technically and economically. .

Dans les murs déjà connus de ce type, et notamment ceux décrits par la déposante dans les brevets français 73 et 79 04497, le processus de fabrication consiste à couler tout d'abord par dessus une armature en treillis une paroi extérieure en béton présentant des ailes transversales entre lesquelles sont déterminés des volumes remplis de polystyrène expansé, assurant l'isolement thermique et phonique du mur, l'ensemble étant renfermé par une paroi intérieure en béton également renforcé par un treillis métallique. In walls already known of this type, and in particular those described by the applicant in French patents 73 and 79 04497, the manufacturing process consists in first of all pouring over a lattice frame an external concrete wall having wings transverse between which are determined volumes filled with expanded polystyrene, ensuring thermal and sound insulation of the wall, the whole being enclosed by an inner concrete wall also reinforced by a wire mesh.

Bien que cette construction donne toute satisfaction du point de vue des caractéristiques mécaniques, elle posait encore quelques problèmes, notamment celui de la corrosion du treillis métallique, qui, noyé dans le béton ne peut être con trôlé, ainsi que celui du poids de ce treillis, dont 1 'accumu- lation n'est pas négligeable dans une construction de grandes dimensions. Although this construction gives all satisfaction from the point of view of mechanical characteristics, it still posed some problems, in particular that of the corrosion of the wire mesh, which, embedded in the concrete cannot be controlled, as well as that of the weight of this mesh. , whose accumulation is not negligible in a construction of large dimensions.

L'invention concerne un nouveau mur dans lequel ces problèmes sont complètement éliminés, grâce à la mise en oeuvre d'un matériau composite constitué par du béton ordinaire dans lequel sont noyées des fibres de polyéthylène, qui assurent le renforcement de la paroi et permettent de supprimer le treillis métallique, et d'obtenir la même solidité pour une épaisseur, et un poids très diminués. The invention relates to a new wall in which these problems are completely eliminated, thanks to the use of a composite material consisting of ordinary concrete in which are embedded polyethylene fibers, which ensure the reinforcement of the wall and allow remove the wire mesh, and obtain the same solidity for a very reduced thickness and weight.

L'invention vise donc en premier lieu un mur caractérisé en ce qu'il se compose de deux parois minces en béton armé par des fibres de polyéthylène, ltespace compris entre ces deux parois étant garni de polystyrène expansé. The invention therefore relates firstly to a wall characterized in that it consists of two thin concrete walls reinforced with polyethylene fibers, the space between these two walls being lined with expanded polystyrene.

L'invention vise également un procédé pour la fabrication de ces murs, consistant à mélanger à sec des agrégats et du ciment pour la formation de béton avec des fibres de poly
3 éthylène dans la proportion de 1Kg de fibre par m de béton, puis à ajouter la quantité d'eau usuelle pour la quantité considérée de ciment et à couler ce matériau composite pour constituer la premiere face d'un mur, puis à mettre en place les blocs de polystyrène expansé destinés à assurer l'isolation de ce mur entre des nervures déterminant l'épaisseur du mur et enfin à couler par dessus le même matériau composite pour constituer la seconde face du mur.The invention also relates to a process for the manufacture of these walls, consisting in dry mixing of aggregates and cement for the formation of concrete with poly fibers.
3 ethylene in the proportion of 1 kg of fiber per m of concrete, then add the usual amount of water for the considered amount of cement and pour this composite material to form the first face of a wall, then put in place blocks of expanded polystyrene intended to insulate this wall between ribs determining the thickness of the wall and finally to flow over the same composite material to constitute the second face of the wall.

De préférence des barres d'acier, éventuellement précontraintes, seront tendues dans le sens de la longueur dans le matériau composite pour éviter le retrait du béton et la fissuration au séchage. Preferably steel bars, possibly prestressed, will be stretched lengthwise in the composite material to avoid shrinkage of the concrete and cracking on drying.

Les joints de préférence de section trapézoidale entre les éléments de murs successifs, constituant une cloison, seront réalisés avec du mortier-colle au lieu de béton, ce qui assure également un meilleur collage et une bonne étanchéité. The joints preferably of trapezoidal section between the elements of successive walls, constituting a partition, will be made with adhesive mortar instead of concrete, which also ensures better bonding and good sealing.

Un tel mur est beaucoup plus mince et plus léger que les murs antérieurs. -Il est également meilleur isolant à épaisseur égale. I1 ntest plus soumis à aucun phénomène de corrosion:
la seule armature métallique conservée est celle des fers verticaux avec bouches en vues de levage.Such a wall is much thinner and lighter than the previous walls. -It is also better insulator with equal thickness. It is no longer subject to any corrosion phenomenon:
the only metal frame retained is that of the vertical bars with mouths in lifting views.

Dans la pratique, pour obtenir I mètre cube du nouveau béton selon l'invention, on mélange à sec 1 kg de fibres de polyéthylene avec I mètre cube d'agrégats et de ciments et au bout de 2 à 4 minutes on ajoute l'eau nécessaire et on coule le béton à la manière usuelle.  In practice, to obtain I cubic meter of the new concrete according to the invention, 1 kg of polyethylene fibers are dry mixed with I cubic meter of aggregates and cements and after 2 to 4 minutes water is added. necessary and the concrete is poured in the usual way.
