Description

La présente invention a pour objet un procédé pour assurer une bonne ventilation et une bonne isolation des murs comprenant une paroi extérieure et une paroi intérieure, entre lesquelles est ménagé un vide qui est partiellement comblé par un matelas ou panneau de matériau isolant destiné à être appliqué sur la paroi intérieure et dont l'épaisseur est inférieure à la dimension correspondante du vide.The subject of the present invention is a method for ensuring good ventilation and good insulation of the walls, comprising an outer wall and an inner wall, between which is created a void which is partially filled by a mattress or panel of insulating material intended to be applied. on the inner wall and whose thickness is less than the corresponding dimension of the void.

Pour maintenir le matelas ou panneau de matériau isolant dans le vide existant entre les parois susdites et assurer la ventilation entre ces dernières, on utilise généralement des fils métalliques galvanisés que l'on immobilise tant bien que mal dans les parois du mur, une des extrémités de chaque fil étant insérée dans la paroi extérieure, l'autre extrémité l'étant dans la paroi intérieure. Après la pose du matelas de matériau isolant, celui-ci est maintenu contre la paroi intérieure par des cavaliers, habituellement en matière plastique, qui sont posés sur les fils et amenés par coulissement contre le matelas de matériau isolant. Cette façon de faire présente divers inconvénients notamment déjà au niveau de la main-d'oeuvre pour la pose correcte des fils métalliques et des cavaliers. On constate ensuite, suite soit au placement défectueux des fils et des cavaliers, soit au coulissement des cavaliers sur les fils, que le matelas de matériau isolant n'est pas bien maintenu contre la paroi interne du mur et que ce matelas souple ou semi-rigide se déforme ou s'affaisse dans le vide dudit mur, ce qui réduit considérablement le pouvoir isolant dudit mur, et la ventilation de celui-ci et provoque, par manque de ventilation, des problèmes d'humidité que l'on tente de résoudre par l'emploi de produits à base de silicones.To keep the mattress or panel of insulating material in the void existing between the aforementioned walls and to ensure ventilation between them, we generally use galvanized metal wires that we immobilize as best we can in the walls of the wall, one end of each wire being inserted in the outer wall, the other end being in the inner wall. After the insulation mat has been laid, it is held against the inner wall by jumpers, usually made of plastic, which are placed on the wires and brought by sliding against the insulation mat. This way of doing things has various drawbacks, especially already at the level of the workforce for the correct laying of the metal wires and the jumpers. It is then observed, following either the faulty placement of the wires and the jumpers, or the sliding of the jumpers on the wires, that the mattress of insulating material is not well held against the internal wall of the wall and that this flexible or semi-rigid mattress deforms or collapses in the vacuum of said wall, which considerably reduces the insulating power of said wall, and the ventilation thereof, and causes, for lack of ventilation, humidity problems that we are trying to resolve by using silicone-based products.

L'invention a pour but de remédier à ces inconvénients et de procurer un procédé permettant de simplifier considérablement la pose correcte du matelas de matériau isolant tout en garantissant le maintien ultérieur dudit matelas en bonne position, c'est-à-dire en contact avec toute la surface de la paroi intérieure, ce qui procure une isolation très poussée et donne l'assurance d'une bonne ventilation du vide existant dans le mur entre la paroi extérieure et le matelas de matériau isolant, cette bonne ventilation éliminant tout risque d'humidité dans le mur et ce, sans avoir recours à des produits coûteux à base de silicones.The object of the invention is to remedy these drawbacks and to provide a method making it possible to considerably simplify the correct installation of the mattress of insulating material while guaranteeing the subsequent maintenance of said mattress in good position, that is to say in contact with the entire surface of the inner wall, which provides very high insulation and gives the assurance of good ventilation of the vacuum existing in the wall between the outer wall and the mattress of insulating material, this good ventilation eliminating any risk of humidity in the wall without having to use expensive silicone-based products.

A cet effet, suivant l'invention, ledit procédé consiste à maçonner simultanément les deux parois du mur, à emprisonner dans la paroi extérieure du mur, l'extrémité d'éléments de maintien du matelas de matériau isolant de telle sorte que ces éléments soient disposés en saillie dans le vide susdit, et à disposer le matelas de matériau isolant dans le vide existant entre ces deux parois, afin que les éléments prennent appui sur le matelas précité pour l'appliquer et le maintenir fermement en place contre la paroi intérieure du mur de manière à ménager entre ledit matelas et la paroi extérieure un vide permanent de ventilation qui est sensiblement constant sur toute la surface du mur, la dimension de la partie des éléments faisant saillie dans le vide du mur, prise perpendiculairement à ce dernier, étant sensiblement égale à la dimension correspondante du vide du mur diminuée de l'épaisseur du matelas de matériau isolant.To this end, according to the invention, said method consists in simultaneously masonrying the two walls of the wall, in trapping in the outer wall of the wall, the end of elements for holding the mattress of insulating material so that these elements are arranged in projection in the aforementioned vacuum, and to have the mattress of insulating material in the vacuum existing between these two walls, so that the elements bear on the aforementioned mattress to apply it and keep it firmly in place against the inner wall of the wall so as to provide between said mattress and the outer wall a permanent ventilation void which is substantially constant over the entire surface of the wall, the dimension of the part of the elements projecting into the void of the wall, taken perpendicularly to the latter, being substantially equal to the corresponding dimension of the wall void minus the thickness of the mat of insulating material.

L'invention a également pour objet un élément de maintien d'un matelas de matériau isolant, disposé dans le vide ventilé d'un mur à double paroi et appliqué sur la paroi intérieure du mur pour la mise en oeuvre du procédé susdit.The invention also relates to a holding element for a mattress of insulating material, placed in the ventilated void of a double-walled wall and applied to the inner wall of the wall for the implementation of the above process.

Suivant l'invention, cet élément est constitué de trois sections réunies entre elles de manière indéformable,une première section constituant l'extrémité précitée de l'élément destinée à être entièrement emprisonnée dans un joint de la paroi extérieure du mur, l'épaisseur de cette section étant tout au plus égale à l'épaisseur dudit joint, une troisième section s'étendant perpendiculairement à la première section et présentant au moins une face plane , opposée à ladite première section, destinée à prendre appui sur la face du matelas de matériau isolant opposée à la paroi intérieure et une deuxième section qui réunit les première et troisième sections précitées et dont la dimension, prise perpendiculairement à la face plane de la troisième section, détermine la dimension correspondante du vide ventilé.According to the invention, this element consists of three sections joined together in a non-deformable manner, a first section constituting the aforementioned end of the element intended to be entirely trapped in a joint of the outer wall of the wall, the thickness of this section being at most equal to the thickness of said joint, a third section extending perpendicular to the first section and having at least one flat face, opposite to said first section, intended to bear on the face of the mat of material insulation opposite to the interior wall and a second section which brings together the first and third sections mentioned above and whose dimension, taken perpendicular to the flat face of the third section, determines the corresponding dimension of the ventilated vacuum.

Suivant une forme de réalisation particulièrement avantageuse de l'invention, les trois sections ont sensiblement la même épaisseur, la troisième section étant plane, les première et troisième sections étant perpendiculaires entre elles et les première et deuxième sections étant en forme de dièdre, l'élément, considérë immobilisé dans la paroi extérieure du mur, étant symétrique par rapport au plan vertical passant par l'arête du dièdre formé par la première section, l'arête du dièdre formé par la deuxième section étant située dans ledit plan vertical, les faces des deux dièdres étant inclinées vers le bas, les angles formés par la deuxième section avec les première et troisième sections étant de l'ordre de 45°, les première et deuxième sections ayant la même dimension prise suivant une direction perpendiculaire à l'arête du dièdre.According to a particularly advantageous embodiment of the invention, the three sections have substantially the same thickness, the third section being planar, the first and third sections being perpendicular to each other and the first and second sections being in the form of a dihedral, the element, considered immobilized in the outer wall of the wall, being symmetrical with respect to the vertical plane passing through the edge of the dihedron formed by the first section, the edge of the dihedron formed by the second section being located in said vertical plane, the faces of the two dihedrons being inclined downwards, the angles formed by the second section with the first and third sections being of the order of 45 °, the first and second sections having the same dimension taken in a direction perpendicular to the edge of the dihedral.

Le procédé suivant l'invention et illustré à la figure 4 est destiné à assurer une excellente ventilation et une bonne isolation d'un mur 1 comprenant une paroi extérieure 2 en briques et une paroi intérieure 3 en blocs de béton, entre lesquelles est ménagé un vide 4 qui est partiellement comblé par un matelas ou panneau, souple ou semi-rigide, de matériau isolant 5 destiné à être appliqué sur la face 6 de la paroi intérieure 3 et dont l'épaisseur e est inférieure à la dimension d du vide, le vide subsistant entre la face 7 de la paroi extérieure 2 et la face 8 du matelas de matériau isolant permettant une circulation d'air assurant la ventilation du mur afin d'éliminer l'humidité qui pourrait y régner suite aux infiltrations d'eau à travers la paroi extérieure 2.The method according to the invention and illustrated in Figure 4 is intended to ensure excellent ventilation and good insulation of a wall 1 comprising an outer wall 2 of bricks and an inner wall 3 of concrete blocks, between which is formed a void 4 which is partially filled with a mattress or panel, flexible or semi-rigid, of insulating material 5 intended to be applied to the face 6 of the interior wall 3 and whose thickness e is less than the dimension d of the void, the vacuum remaining between the face 7 of the outer wall 2 and the face 8 of the mattress of insulating material allowing air circulation ensuring the ventilation of the wall in order to eliminate the humidity which could reign there following water infiltration at through the outer wall 2.

Ce procédé consiste à maçonner simultanément les deux parois 2 et 3, à emprisonner dans la paroi extérieure 2 du mur, au fur et à mesure que les parois s'élèvent et en même temps que les pièces d'accrochage (non représentées) des parois 2 et 3, l'extrémité 9 d'éléments de maintien 10 du matelas de matériau isolant 5 afin que ces éléments 10 soient disposés en saillie dans le vide 4 pour prendre appui sur le matelas 5, introduit ultérieurement entre les parois 2 et 3 , de manière à appliquer et maintenir fermement ce matelas en place contre la face 6 de la paroi intérieure 3 et pour ménager entre ce matelas 5 et la face 7 de la paroi extérieure 2 un vide permanent de ventilation 11 qui est sensiblement constant sur toute la surface du mur, la dimension de la partie des éléments 10 en saillie dans le vide du mur, prise perpendiculairement à celui-ci, étant sensiblement égale à la dimension correspondante du vide 4 du mur diminuée de l'épaisseur e du matelas de matériau isolant 5. Les extrémités 9 des éléments 10 sont emprisonnées dans les joints 12 des briques . constituant la paroi extérieure 2 du mur, afin que les éléments 10 soient alignés en rangées sensiblement verticales et sensiblement équidistantes. Ces éléments de maintien 10 sont avantageusement disposés en quinconce et on prévoit avantageusement six éléments 10 par m2 de paroi extérieure 2 de mur, la face d'appui 13 des éléments sur le matelas 5 ayant avantageusement une surface de l'ordre de 1 dm2.This process consists of simultaneously masonry the two walls 2 and 3, to trap in the outer wall 2 of the wall, as the walls rise and at the same time as the hanging pieces (not shown) of the walls 2 and 3, the end 9 of holding elements 10 of the mattress of insulating material 5 so that these elements 10 are arranged projecting into the void 4 to bear on the mattress 5, introduced subsequently between the walls 2 and 3, so as to apply and firmly hold this mattress in place against the face 6 of the inner wall 3 and to provide between this mattress 5 and the face 7 of the outer wall 2 a permanent ventilation vacuum 11 which is substantially constant over the entire surface of the wall, the dimension of the part of the elements 10 projecting into the void of the wall, taken perpendicularly to the latter, being substantially equal to the corresponding dimension of the void 4 of the wall reduced by the thickness e of the mattress of insulating material 5 The ext 9 of the elements 10 are trapped in the joints 12 of the bricks. constituting the outer wall 2 of the wall, so that the elements 10 are aligned in substantially vertical and substantially equidistant rows. These retaining elements 10 are advantageously arranged in staggered rows and advantageously six elements 10 are provided per m2 of external wall 2 of wall, the bearing face 13 of the elements on the mattress 5 advantageously having a surface of the order of 1 dm2.

L'élément de maintien 10 pour la mise en oeuvre du procédé susdit est, suivant l'invention et comme représenté aux dessins, constitué de trois sections 14,15 et 16 réunies entre elles afin que l'élément soit indéformable. La section 14 constitue l'extrémité 9 de l'élément destinée à être complètement noyée dans un des joints 12 de la paroi extérieure 2 et son épaisseur est inférieure à celle du joint. La section 16, qui est perpendiculaire à la section 14, présente la face plane 13 de l'élément destinée à prendre appui sur la face 8 précitée du matelas de matériau isolant 5 et est réunie à la section 14 par la section 15 dont la dimension, prise perpendiculairement à la face 13 susdite, détermine la dimension du vide ventilé 11.The holding element 10 for implementing the above method is, according to the invention and as shown in the drawings, consisting of three sections 14, 15 and 16 joined together so that the element is undeformable. Section 14 constitutes the end 9 of the element intended to be completely embedded in one of the joints 12 of the outer wall 2 and its thickness is less than that of the joint. Section 16, which is perpendicular to section 14, has the flat face 13 of the element intended to bear on the aforementioned face 8 of the mattress of insulating material 5 and is joined to section 14 by section 15 whose dimension , taken perpendicular to the above-mentioned face 13, determines the dimension of the ventilated vacuum 11.

Pour que l'eau de condensation qui pourrait se former sur les éléments 10 ne stagne pas sur ces derniers et s'écoule vers la paroi extérieure 2, ventilée sur ses deux faces, plutôt que vers le matelas de matériau isolant 5, la section 15 est inclinée pour que son raccordement 17 à la section 16 soit situé à un niveau plus élevé que son raccordement 18 à la section 14.So that the water of condensation which could form on the elements 10 does not stagnate on the latter and flows towards the external wall 2, ventilated on its two faces, rather than towards the mattress of insulating material 5, the section 15 is inclined so that its connection 17 to section 16 is located at a higher level than its connection 18 to section 14.

Les sections 14, 15 et 16 de l'élément 10 ont avantageusement la même épaisseur. Dans la forme de réalisation illustrée à la figure 1, les sections 14 et 16 sont planes et perpendiculaires entre elles et l'élément est symétrique par rapport au plan vertical passant par l'axe longitudinal 19 de la section 14, l'élément étant considéré dans la position qu'il occupe lorsqu'il est fixé à 1a paroi 2. La section 15 est en forme de dièdre, qui se raccorde sensiblement au centre de la section 16, qui a son arête 20 située dans le plan vertical susdit et ses faces 21 inclinées vers le bas. Les angles fl formés par la section 15 avec les sections 14 et 16 sont de 45° et les sections 14 et 15 ont la même dimension d' prise suivant une direction perpendiculaire à l'arête 20 du dièdre. La section 16 présente une découpe 22 qui s'étend en dessous du raccordement 17 précité et est délimite par celui-ci et par deux plans parallèles au plan de symétrie de l'élément et passant par les bords 23 des sections 14 et 15. L'élément 10, qui pourrait être réalisé en tôle emboutie, est avantageusement réalisé en matière plastique injectée.The sections 14, 15 and 16 of the element 10 advantageously have the same thickness. In the embodiment illustrated in FIG. 1, the sections 14 and 16 are plane and perpendicular to each other and the element is symmetrical with respect to the vertical plane passing through the longitudinal axis 19 of the section 14, the element being considered in the position which it occupies when it is fixed to the wall 2. The section 15 is in the form of a dihedral, which is connected substantially to the center of the section 16, which has its edge 20 situated in the above-mentioned vertical plane and its faces 21 inclined downwards. The angles f1 formed by section 15 with sections 14 and 16 are 45 ° and sections 14 and 15 have the same grip dimension in a direction perpendicular to the edge 20 of the dihedron. Section 16 has a cutout 22 which extends below the above-mentioned connection 17 and is delimited by the latter and by two planes parallel to the plane of symmetry of the element and passing through the edges 23 of sections 14 and 15. L element 10, which could be made of stamped sheet metal, is advantageously made of injected plastic.

Pour assurer un meilleur accrochage de l'extrémité 9 de l'élément dans les joints 12 de la paroi 2, la première section 14, constituant cette extrémité présente avantageusement, comme montré aux figures 2 à 5, la forme d'un dièdre qui se raccorde au dièdre formé par la deuxième section 15. L'arête 19 de ce dièdre formé par la première section est située dans le plan vertical susdit, l'élément étant symétrique par rapport à ce plan et les faces 21' de ce dièdre étant inclinées vers le bas.To ensure better attachment of the end 9 of the element in the joints 12 of the wall 2, the first section 14, constituting this end advantageously has, as shown in Figures 2 to 5, the shape of a dihedral which is connects to the dihedral formed by the second section 15.
