- Such an insulation method can thus be implemented on monuments, for example historical ones, without risking denaturing them.

Description
Le système d'isolation consiste à introduire un isolant dans un entraxe d'un mur en pierre. Plus particulièrement, l'invention propose un moyen et un procédé d'installation d'une isolation au sein d'un mur en pierre existant.The insulation system consists of introducing an insulator in a center distance of a stone wall. More particularly, the invention provides a means and method for installing insulation within an existing stone wall.
Habituellement, l'isolation d'un bâtiment, par exemple une habitation, s'effectue lors de sa construction. Des systèmes d'isolation tels que par exemple de la laine de verre, sont alors intégrés dans les murs formant l'habitation. Cependant, pour les constructions déjà établies, l'isolation a posteriori s'avère plus complexe.Usually, the insulation of a building, for example a dwelling, is carried out during its construction. Insulation systems such as glass wool, for example, are then integrated into the walls forming the dwelling. However, for buildings already established, the insulation a posteriori proves to be more complex.
Des solutions existent pour isoler des constructions déjà implantées et consistent principalement en une isolation par l'extérieur en recouvrant les murs existants par des plaques isolantes. Cette solution bien qu'efficace, ne peut s'appliquer à tous les murs.Solutions exist to insulate constructions already established and consist mainly of insulation from the outside by covering the existing walls with insulating plates. This solution, although effective, cannot be applied to all walls.
En effet, pour les bâtiments par exemple anciens et/ou classés, l'isolation par l'extérieur tend à dénaturer les constructions en les camouflant. Notamment, l'utilisation de l'isolation par l'extérieur au moyen de panneaux, recouvre des murs dont les pierres octroient un esthétisme particulier au bâtiment.Indeed, for old and/or listed buildings, for example, external insulation tends to distort the constructions by camouflaging them. In particular, the use of insulation from the outside by means of panels, covers walls whose stones give a particular aesthetic to the building.
Ainsi, l'invention propose une solution permettant d'isoler efficacement des bâtiments déjà construits, sans dénaturer leurs façades.Thus, the invention proposes a solution making it possible to effectively insulate buildings already constructed, without distorting their facades.
L'invention porte sur un système d'isolation d'un mur en pierre comprenant au moins une paroi intérieure et une paroi extérieure espacées l'une de l'autre pour former un entraxe, un béton hydrofuge s'étendant au moins sous la paroi intérieure et/ou la paroi extérieure, le système d'isolation comprenant un isolant imputrescible situé dans l'entraxe et lié à l'une ou l'autre de la paroi intérieure ou la paroi extérieure par un système de rails métalliques, l'isolant imputrescible étant recouvert d'un film pare-vapeur, le système d'isolation étant configuré de telle sorte qu'une lame d'air subsiste dans l'entraxe, la paroi intérieure et la paroi extérieure étant reliées l'une à l'autre par des tiges filetées scellées chimiquement dans au moins une de la paroi intérieure ou de la paroi extérieure.The invention relates to a system for insulating a stone wall comprising at least an interior wall and an exterior wall spaced apart from each other to form a center distance, a water-repellent concrete extending at least under the wall interior and/or the exterior wall, the insulation system comprising rot-proof insulation located in the center distance and linked to one or the other of the interior wall or the exterior wall by a system of metal rails, the insulation rot-proof being covered with a vapor barrier film, the insulation system being configured in such a way that an air gap remains in the center distance, the inner wall and the outer wall being connected to each other by threaded rods chemically sealed in at least one of the inner wall or the outer wall.
Selon une caractéristique de l'invention, les tiges filetées sont disposées en quinconce les unes par rapport aux autres.According to one characteristic of the invention, the threaded rods are staggered relative to each other.

Selon un exemple de l'invention, les tiges filetées 30 présentent un diamètre compris entre 12mm et 14mm. Les tiges filetées 30 une fois introduites dans les perçages formés dans la paroi extérieure 14b, sont scellées chimiquement.The outer wall 14b is then pierced in order to introduce the threaded
La paroi extérieure 14b est percée en quiconque de telle sorte que les tiges filetées 30 soient disposées en quiconque.The outer wall 14b is pierced in anyone so that the threaded
Une fois les tiges filetées 30 installées, les rails métalliques 22, ici les rails horizontaux 22a, sont installés sur la paroi extérieure 14b. Plus particulièrement, les rails horizontaux 22a sont solidaires de la face de la paroi extérieure 14b destinée à être dans l'entraxe 18 évoqué précédemment.Once the threaded
Une fois les rails métalliques 22 installés, un isolant imputrescible 20 est disposé contre la paroi extérieure 14b, et est notamment solidarisé avec les rails horizontaux 22a précédemment installés. On comprend alors que l'isolant imputrescible 20 est transpercé par les tiges filetées 30 précédemment solidarisées à la paroi extérieure 14b.Once the metal rails 22 have been installed, a rot-
Par la suite, le film pare-vapeur 24 est disposé en recouvrement de l'isolant imputrescible 20 tel qu'évoqué précédemment. Le film pare-vapeur 24 est lui aussi traversé par les tiges filetées 30.Subsequently, the
Une fois le film pare-vapeur 24 installé, les rails verticaux 22b sont installés contre l'isolant imputrescible 20, et plus particulièrement contre le film pare-vapeur 24 précédemment installé.Once the
Ensuite, un lattis métallique 34, visible à la
On comprend par ailleurs que l'épaisseur des rails verticaux 22b, selon la direction transversale T, permet de former la lame d'air 26 de dimension transversale comprise entre 0,5cm et 50cm entre le film pare-vapeur et la paroi intérieur 14a.It is also understood that the thickness of the vertical rails 22b, in the transverse direction T, makes it possible to form the
Une fois le lattis métallique 34 installé, la paroi intérieure 14a est remontée contre le lattis métallique 34 et de telle sorte à former l'entraxe 18 tel qu'évoqué précédemment. Ainsi, on obtient le mur 10 tel que décrit ci-dessus.Once the
Le mur 10 ainsi obtenu présente une épaisseur comprise entre 54cm et 106cm.The
Le système d'isolation du mur et son procédé associé selon l'invention sont avantageux en ce qu'ils permettent de conserver l'aspect et les composants du mur existant tout en apportant une isolation thermique optimale dudit mur. Un tel procédé d'isolation peut ainsi être mis en oeuvre sur des monuments par exemple historiques sans risquer de les dénaturer.The wall insulation system and its associated method according to the invention are advantageous in that they make it possible to preserve the appearance and the components of the existing wall while providing optimal thermal insulation of said wall. Such an insulation method can thus be implemented on monuments, for example historical ones, without risking denaturing them.
