Abstract

Description

La présente invention a pour objet un élément de maintien d'un matelas de matériau isolant dans des murs isolés et ventilés qui sont constitués d'une paroi extérieure et d'une paroi intérieure entre lesquelles est ménagé un vide qui est partiellement comblé par le matelas, dont l'épaisseur est inférieure à la dimension correspondante du vide et qui est appliqué et maintenu par les éléments sur la paroi intérieure, cet élément de maintien comprenant une extrémité destinée à être emprisonnée dans un joint horizontal de la paroi extérieure du mur ainsi qu'un organe présentant une face plane s'étendant perpendiculairement à cette extrémité et destinée à prendre appui sur la face du matelas de matériau isolant qui est opposée à la paroi intérieure.The subject of the present invention is a holding element for a mattress of insulating material in insulated and ventilated walls which consist of an outer wall and an inner wall between which a void is formed which is partially filled by the mattress. , whose thickness is less than the corresponding dimension of the void and which is applied and maintained by the elements on the interior wall, this retaining element comprising an end intended to be trapped in a horizontal joint of the exterior wall of the wall as well as 'A member having a flat face extending perpendicularly to this end and intended to bear on the face of the mattress of insulating material which is opposite to the inner wall.

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 intérieure 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, de 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 in terms of labor 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 interior wall of the wall and that this flexible or semi-mattress rigid deforms or collapses in the vacuum of said wall, which considerably reduces the insulating power of said wall, and the ventilation thereof, and causes, due to lack of ventilation, humidity problems which one is trying to solve by the use of silicone-based products.

Pout remédier à ces inconvénients, on a déjà pensé, suivant BE-A-897.588, à maintenir le matelas isolant à l'aide d'éléments constitués de deux plats réunis perpendiculairement l'un à l'autre, un des plats étant destiné à être partiellement logé dans un joint horizontal de la paroi extérieure du mur tandis que l'autre plat prend appui sur la matelas isolant appliqué sur la paroi intérieure du mur, le plat destiné à être introduit dans le joint susdit comportant des repères, disposés parallèlement à l'autre plat, qui permettent d'ajuster la position de chaque élément dans les joints en fonction, d'une part, du vide existant entre les parois intérieure et extérieure du mur et, d'autre part, de l'épaisseur du matelas isolant. Si ces éléments constituent un progrès par rapport aux fils métalliques galvanisés précités, ils présentent encore des inconvénients majeurs à savoir notamment, d'une part, nécessité de régler, lors de la pose de chaque élément de maintien, la position de ce dernier en alignant le bon repère par rapport à la paroi extérieure du mur, d'où perte de temps importante et risque d'erreur au cours de la mise en place des éléments et, d'autre part, manque de stabilité de l'élément dans le joint tant que le mortier n'a pas fait prise, d'où risque important de déplacer un élément, correctement posé, dès qu'il est soumis à la moindre sollicitation.To overcome these drawbacks, it has already been thought, according to BE-A-897.588, to maintain the insulating blanket using elements made up of two plates joined perpendicularly to one another, one of the dishes being intended for be partially housed in a horizontal joint on the outer wall of the wall while the other plate rests on the insulating mat applied to the inner wall of the wall, the dish intended to be introduced into the aforementioned joint comprising marks, arranged parallel to the other plate, which allows to adjust the position of each element in the joints according, on the one hand, to the vacuum existing between the inner and outer walls of the wall and, on the other hand, to the thickness of the mattress insulating. If these elements constitute an improvement compared to the aforementioned galvanized metal wires, they still have major drawbacks, namely in particular, on the one hand, the need to adjust, during the fitting of each holding element, the position of the latter by aligning the correct mark relative to the external wall of the wall, hence significant loss of time and risk of error during the positioning of the elements and, on the other hand, lack of stability of the element in the joint as long as the mortar has not set, hence the significant risk of moving an element, correctly laid, as soon as it is subjected to the slightest stress.

L'invention a pour but de remédier à ces divers inconvénients et de procurer un élément de maintien qui est conçu en fonction de la distance déterminée et souhaitée qui sépare la paroi extérieure du mur de la face du matelas isolant la plus proche de cette dernière. Cet élément, qui est prévu pour buter automatiquement, lorsqu'il est en bonne position, contre les matériaux de construction entre lesquels sont ménagés les joints de la paroi extérieure du mur avec lesquels il est destiné à coopérer, peut donc être mis correctement en place très rapidement sans mesurage et sans tenir compte de repères. De plus, comme cet élément s'appuie sur les matériaux de construction susdits, il reste stable lorsqu'il subit des sollicitations avant la prise dumortier du joint dans lequel il est partiellement emprisonné. Ledit élément permet donc 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 various drawbacks and to provide a holding element which is designed as a function of the determined and desired distance which separates the outer wall of the wall from the face of the insulating mat closest to the latter. This element, which is intended to automatically abut, when in a good position, against the building materials between which the joints of the external wall of the wall with which it is intended to cooperate are formed, can therefore be correctly placed very quickly without measurement and without taking into account benchmarks. In addition, as this element is based on the aforementioned construction materials, it remains stable when it undergoes stresses before the mortar grip of the joint in which it is partially trapped. Said element therefore makes 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 interior wall, which provides insulation. very high 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 moisture in the wall and without using products expensive silicone-based.

A cet effet, suivant l'invention, ledit élément de maintien est constitué de trois sections réunies entre elles de manière indéformable, une première section qui consistitue l'extrémité précitée de l'élément, dont l'épaisseur est tout au plus égale à l'épaisseur d'un joint de la paroi extérieure du mur et qui est destinée à être entièrement emprisonnée dans ce dernier, une troisième section s'étendant perpendiculairement à la première section et présentant la face plane précitée, opposée à ladite première section, destinée à prendre appui sur la face susdite du matelas de matériau isolant et une deuxième section, qui réunit les première et troisième sections obliquement par rapport à la face plane susdite et dont la dimension, prise perpendiculairement à cette dernière, est sensiblement égale à la dimension correspondante du vide diminuée de l'épaisseur du matelas.To this end, according to the invention, said retaining element consists of three sections joined together in a non-deformable manner, a first section which consists of the aforementioned end of the element, the thickness of which is at most equal to l thickness of a joint of the outer wall of the wall and which is intended to be entirely trapped in the latter, a third section extending perpendicular to the first section and having the aforementioned flat face, opposite to said first section, intended for bear on the aforesaid face of the mattress of insulating material and a second section, which joins the first and third sections obliquely to the aforementioned flat face and the dimension of which, taken perpendicularly to the latter, is substantially equal to the corresponding dimension of the vacuum reduced by the thickness of the mattress.

Suivant une forme de réalisation avantageuse de l'invention, l'obliquité de la deuxième section est telle que, lorsque la première section est immobilisée dans le joint, son raccordement à la troisième section est situé à un niveau plus élevé que celui de son raccordement à la première section.According to an advantageous embodiment of the invention, the obliquity of the second section is such that, when the first section is immobilized in the joint, its connection to the third section is located at a higher level than that of its connection to the first section.

Suivant un mode de réalisation particulièrement avantageuse de l'invention, la première section, la deuxième section et la troisième section, qui est plane et perpendiculaire à la permière section, ont sensiblement la même épaisseur, les première et deuxième sections étant en forme de dièdre, l'élément étant, lorqu'il occupe une position correspondant à sa position d'immobilisation dans un joint, symétrique par rapport au plan vertical passant par l'arête du dièdre formé par la première section et dans lequel est située l'arête du dièdre formé par la deuxième section, les première et deuxième sections ayant la même dimension prise suivant une direction perpendiculaire au plan vertical susdit, les faces des deux dièdres formés par les première et deuxième sections étant inclinées vers le bas tandis que les angles formés par la deuxième section avec les première et troisième section sont de l'ordre de 45°.According to a particularly advantageous embodiment of the invention, the first section, the second section and the third section, which is plane and perpendicular to the first section, have substantially the same thickness, the first and second sections being in the form of a dihedral. , the element being, when it occupies a position corresponding to its immobilization position in a joint, symmetrical with respect to the vertical plane passing through the edge of the dihedron formed by the first section and in which the edge of the dihedral formed by the second section, the first and second sections having the same dimension taken in a direction perpendicular to the above vertical plane, the faces of the two dihedra formed by the first and second sections being inclined downward while the angles formed by the second section with the first and third sections are of the order of 45 °.

Le mur isolé et ventilé 1, illustré à la figure 5, comprend 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 insulated and ventilated wall 1, illustrated in FIG. 5, comprises an outer wall 2 made of bricks and an inner wall 3 made of concrete blocks, between which is created a void 4 which is partially filled by 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 vacuum, the vacuum remaining between the face 7 of the exterior wall 2 and the face 8 of the mattress of insulating material allowing an air circulation ensuring the ventilation of the wall in order to eliminate the humidity which could reign there following the infiltration of water through the external wall 2.

Pour réaliser le mur 1, on maçonne simultanément les deux parois 2 et 3 et on emprisonne dans la paroi extérieure 2 du mur, au fur et à mesure que les parois s'élèvent et en même temps qu'on pose les pièces d'accrochage (non représentées) des parois 2 et 3, l'extrémité 9 des 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, est 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 horizontaux 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 du mur, la face d'appui 13 des éléments sur le matelas 5 ayant avantageusement une surface de l'ordre de 1 dm2.To make the wall 1, the two walls 2 and 3 are built simultaneously and trapped in the outer wall 2 of the wall, as the walls rise and at the same time that the hanging pieces are placed (not shown) of the walls 2 and 3, the end 9 of the retaining elements 10 of the mattress of insulating material 5 so that these elements 10 are 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, is 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 ends 9 of the elements 10 are trapped in the horizontal 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 the wall, the bearing face 13 of the elements on the mattress 5 advantageously having a surface of the order of 1 dm2.

L'élément 10, suivant l'invention est, 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 horizontaux 12 de la paroi extérieure 2 et son épaisseur est inférieure à celle de ce 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, qui est oblique par rapport aux sections 14 et 16 et dont la dimension, prise perpendiculairement à la face 13 susdite est égale à la dimension d du vide 4 diminuée de l'épaisseur e du matelas isolant 5 et détermine la dimension correspondante du vide ventilé 11. Les éléments de maintien 10 sont fabriqués avec des sections 15 de dimensions susdites différentes et on choisit les éléments à utiliser en fonction de la dimension' souhaitée pour le vide ventilé 11.The element 10, according to the invention is, as shown in the drawings, consisting of three sections 14, 15 and 16 joined together so that the element is non-deformable. Section 14 constitutes the end 9 of the element intended to be completely embedded in one of the horizontal joints 12 of the outer wall 2 and its thickness is less than that of this 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, which is oblique to sections 14 and 16 and the dimension of which, taken perpendicular to the aforesaid face 13 is equal to the dimension d of the vacuum 4 minus the thickness e of the insulating mat 5 and determines the corresponding dimension of the ventilated vacuum 11. The holding elements 10 are manufactured with sections 15 of aforementioned different dimensions and the elements to be used are chosen according to the dimension desired for the ventilated vacuum 11.

Comme on le voit à la figure 5, les éléments de maintien 10 se mettent facilement et automatiquement en position correcte en faisant buter leur section inclinée 15, en 24, contre les briques formant la paroi extérieure 2 du mur. Pour accroître la stabilité des éléments de maintien 10 dans le mortier frais constituant les joints 12, on place avantageusement les éléments 10 à l'intersection d'un joint horizontal et d'un joint vertical pour que la section 15 des éléments prenne appui simultanément, à l'endroit 24 susdit, sur les arêtes des briques bordant le joint horizontal et le joint vertical.As seen in Figure 5, the holding elements 10 are easily and automatically put in the correct position by abutting their inclined section 15, at 24, against the bricks forming the outer wall 2 of the wall. To increase the stability of the holding elements 10 in the fresh mortar constituting the joints 12, the elements 10 are advantageously placed at the intersection of a horizontal joint and a vertical joint so that the section 15 of the elements is supported simultaneously, in place 24 above, on the edges of the bricks bordering the horizontal joint and the vertical joint.

Pour que l'eau qui pourrait se condenser 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 celui de son raccordement 18 à la section 14.So that the water which could condense 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 that of 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 placé dans un joint 12 de la 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 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 reccordement 17 précité et est délimitée 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.Sections 14, 15 and 16 of Element 10 have advantageously the same thickness. In the embodiment illustrated in FIG. 1, the sections 14 and 16 are plane and perpendicular to one another 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 it occupies when it is placed in a joint 12 of 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 plane vertical above and its faces 21 inclined downwards. The angles 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 dihedral. Section 16 has a cutout 22 which extends below the abovementioned overlap 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. The edge 19 of this dihedral formed by the first section is located in the above-mentioned vertical plane, the element being symmetrical with respect to this plane and the faces 21 ′ of this dihedron being inclined down.

Il doit être entendu que l'invention n'est nullement limitée aux formes de réalisation décrites et que bien des modifications pourraient être apportées à ces dernières sans sortir du cadre du présent brevet, la protection étant déterminée par la teneur des revendications.It should be understood that the invention is in no way limited to the embodiments described and that many modifications could be made to these without departing from the scope of this patent, protection being determined by the content of the claims.
