Description

Le domaine de l'invention est celui de la conception et de la fabrication d'ouvrants tels que les fenêtres pour bâtiments.The field of the invention is that of the design and manufacture of openings such as windows for buildings.

Plus précisément, l'invention concerne un mur de bâtiment avec un bloc de fenêtre pour la rénovation d'un bâtiment avec isolation thermique par l'extérieur (ITE).More specifically, the invention relates to a building wall with a window block for the renovation of a building with external thermal insulation (ITE).

L'évolution des normes environnementales implique que de nombreux bâtiments doivent être rénovés pour éviter les échanges thermiques et notamment les consommations importantes de chauffage ou de climatisation.The evolution of environmental standards means that many buildings must be renovated to avoid heat exchange and in particular high consumption of heating or air conditioning.

Pour cela, une solution fortement utilisée consiste à poser une couche d'isolation thermique à l'extérieur du bâtiment.For this, a widely used solution consists of laying a layer of thermal insulation on the outside of the building.

En effet, les études tendent à démontrer que l'isolation par l'extérieur procure de meilleures performances que l'isolation par l'intérieur.Indeed, studies tend to show that exterior insulation provides better performance than interior insulation.

De plus, cette solution permet de conserver un volume interne au bâtiment égal au volume interne avant rénovation. Autrement dit, en isolant par l'extérieur du bâtiment, la couche isolante ne réduit pas le volume interne des pièces et les occupants du bâtiment peuvent conserver une surface utile identique tout en bénéficiant d'une consommation énergétique réduite puisque les besoins en chauffage et/ou climatisation sont moins importants.In addition, this solution makes it possible to maintain an internal volume of the building equal to the internal volume before renovation. In other words, by insulating from the outside of the building, the insulating layer does not reduce the internal volume of the rooms and the occupants of the building can maintain an identical useful surface while benefiting from reduced energy consumption since the needs for heating and/or or air conditioning are less important.

Outre l'isolation, les ouvrants tels que les portes et fenêtres par exemple sont généralement changés. Les nouveaux ouvrants permettent également de réduire les besoins en chauffage et/ou climatisation et permettent d'offrir un nouveau « visage extérieur » au bâtiment.In addition to the insulation, openings such as doors and windows, for example, are generally changed. The new openings also make it possible to reduce heating and/or air conditioning needs and provide a new “outside face” to the building.

Un type d'ouvrant connu comprenant un pré-cadre est décrit par dans le document de brevet publié sous le numéro DE 10 2004 015364 .A known type of opening comprising a pre-frame is described by in the patent document published under the number DE 10 2004 015364 .

Toutefois, lorsque la rénovation d'un bâtiment fait intervenir l'isolation par l'extérieur, l'intégration de nouvelles fenêtres peut devenir compliquée.However, when the renovation of a building involves external insulation, the integration of new windows can become complicated.

En effet, l'utilisation d'une couche isolante par l'extérieur demande une structure particulière du bloc fenêtre pour que celui-ci soit à la fois facilement installable, mais également qu'il assure une isolation thermique importante entre l'intérieur et l'extérieur du bâtiment.Indeed, the use of an insulating layer from the outside requires a particular structure of the window unit so that it is both easily installable, but also that it provides significant thermal insulation between the interior and the exterior. building exterior.

Le document de brevet publié sous le numéro EP2333219 décrit un ensemble comprenant un pré-cadre portant à sa périphérie une isolation et un dormant de fenêtre monté dans le pré-cadre, le pré-cadre étant destiné à être inséré dans un tunnel de fenêtre d'un mur d'un bâtiment par l'extérieur.The patent document published under number EP2333219 describes an assembly comprising a pre-frame carrying insulation at its periphery and a window frame mounted in the pre-frame, the pre-frame being intended to be inserted into a window tunnel of a wall of a building through the 'outside.

Cet ensemble n'est pas sans inconvénient.This set is not without its drawbacks.

En effet, le pré-cadre et l'isolation périphérique présentent une profondeur différente. Plus précisément, l'isolation périphérique s'étend sur une profondeur supérieure à celle sur laquelle s'étend le pré-cadre.Indeed, the pre-frame and the peripheral insulation have a different depth. More specifically, the peripheral insulation extends over a depth greater than that over which the pre-frame extends.

Cette différence de profondeur pose notamment des problèmes en termes d'installation de l'ensemble ainsi qu'en termes de tenue de l'isolation périphérique préalablement à l'installation de l'ensemble et lorsque l'ensemble est installé.This difference in depth poses problems in particular in terms of installation of the assembly as well as in terms of holding the peripheral insulation prior to the installation of the assembly and when the assembly is installed.

L'installation de l'ensemble est rendue difficile notamment lorsque le tunnel présente une profondeur importante. Il est alors nécessaire de correctement positionner l'ensemble en regard du tunnel avant insertion sous peine de dégrader l'isolation périphérique par frottement contre les parois du tunnel.The installation of the assembly is made difficult in particular when the tunnel has a significant depth. It is then necessary to position the assembly correctly opposite the tunnel before insertion, otherwise the peripheral insulation will be damaged by friction against the walls of the tunnel.

Par ailleurs, le frottement de l'isolation périphérique contre les parois du tunnel tend à diminuer l'épaisseur de l'isolation périphérique et, par conséquent, à réduire le pouvoir isolant de cette dernière par remplissage du vide entre le pré-cadre et les parois du tunnel.Moreover, the friction of the peripheral insulation against the walls of the tunnel tends to reduce the thickness of the peripheral insulation and, consequently, to reduce the insulating power of the latter by filling the void between the pre-frame and the tunnel walls.

La manipulation de l'ensemble préalablement à l'installation peut également être rendue particulièrement difficile. En effet, par leur différence de profondeur, lorsque l'ensemble est manipulé en saisissant le pré-cadre, l'isolation périphérique se trouve alors en porte à faux et tend à se courber. Dès lors, l'installation de l'ensemble dans le tunnel devient difficile puisqu'il faut redresser l'isolation périphérique pour que celle-ci soit rectiligne de sorte à permettre son insertion dans le tunnel.Handling the assembly prior to installation can also be made particularly difficult. Indeed, by their difference in depth, when the assembly is manipulated by grasping the pre-frame, the peripheral insulation is then cantilevered and tends to bend. Therefore, the installation of the assembly in the tunnel becomes difficult since it is necessary to straighten the peripheral insulation so that it is straight so as to allow its insertion into the tunnel.

Pour pallier à cela, il est possible d'augmenter l'épaisseur de l'isolation périphérique de sorte à la rigidifier. Toutefois, une telle augmentation de l'épaisseur réduit l'espace alloué à l'ouvrant et réduit d'autant la luminosité entrante dans le bâtiment pour une fenêtre, ou l'espace de passage pour une porte.To overcome this, it is possible to increase the thickness of the peripheral insulation so as to stiffen it. However, such an increase in thickness reduces the space allocated to the sash and correspondingly reduces the light entering the building for a window, or the passage space for a door.

En outre, une telle augmentation de l'épaisseur va alors à l'encontre du souhait général des occupants qui souhaitent des volumes internes les plus lumineux possibles, ou à tout le moins au moins aussi lumineux qu'avant la rénovation du bâtiment, tout en étant correctement isolés thermiquement. C'est d'ailleurs pour répondre à cette attente, que des revêtements isolants de faible épaisseur ont été développés.In addition, such an increase in thickness then goes against the general wish of the occupants who want the brightest possible internal volumes, or at the very least at least as bright as before the renovation of the building, while being properly thermally insulated. It is moreover to meet this expectation that thin insulating coatings have been developed.

Les documents de brevets publiés sous les numéros DE102004015364 , CH671995 , EP3315707 EP2333219 , EP1464787 et DE202009016152 décrivent des ensembles comprenant des cadres et/ou des pré-cadres.The patent documents published under the numbers DE102004015364 , CH671995 , EP3315707 EP2333219 , EP1464787 And DE202009016152 describe assemblies comprising frames and/or pre-frames.

L'invention a notamment pour objectif de palier les inconvénients de l'art antérieur. Plus précisément, l'invention a pour objectif de proposer un mur de bâtiment avec un ensemble comprenant un pré-cadre portant à sa périphérie une isolation et un dormant de fenêtre monté dans le pré-cadre, qui soit simple et rapide d'installation.The object of the invention is in particular to overcome the drawbacks of the prior art. More specifically, the invention aims to provide a building wall with an assembly comprising a pre-frame carrying insulation at its periphery and a window frame mounted in the pre-frame, which is simple and quick to install.

L'invention a également pour objectif de fournir un tel ensemble dont la manipulation ne présente pas de risque d'endommagement de l'isolation périphérique, ou à tout le moins une dégradation trop faible pour réduire le pouvoir d'isolation thermique de l'ensemble.The invention also aims to provide such an assembly, the handling of which does not present any risk of damage to the peripheral insulation, or at the very least a degradation that is too slight to reduce the thermal insulation power of the assembly. .

L'invention a en outre pour objectif de fournir un tel ensemble qui présente un passage de luminosité important.The invention also aims to provide such an assembly which has a high luminosity passage.

Ces objectifs, ainsi que d'autres qui apparaîtront par la suite, sont atteints grâce à l'invention qui a pour objet un mur de bâtiment selon la revendication 1.These objectives, as well as others which will appear subsequently, are achieved thanks to the invention which relates to a building wall according to claim 1.

Un tel ensemble permet de faciliter la rénovation des bâtiments, notamment la mise en place de fenêtres offrant une bonne isolation à la fois acoustique et thermique.Such a set facilitates the renovation of buildings, in particular the installation of windows offering good insulation, both acoustic and thermal.

En effet, lors de la rénovation d'un bâtiment, on peut insérer la première partie du pré-cadre depuis l'extérieur du bâtiment (toute une phase des travaux pouvant donc être réalisée sans avoir à entrer dans les logements éventuellement occupés par des résidents), puis la deuxième partie depuis l'intérieur du bâtiment.Indeed, during the renovation of a building, the first part of the pre-frame can be inserted from outside the building (a whole phase of the work can therefore be carried out without having to enter the dwellings possibly occupied by residents ), then the second part from inside the building.

Par ailleurs la présence de la membrane d'isolation à l'air permet de conférer au bloc fenêtre (comprenant la première patrie du pré-cadre et la deuxième partie du pré-cadre) une bonne isolation thermique. L'air pouvant pénétrer depuis l'extérieur est ainsi bloqué par la membrane qui s'étend entre la deuxième partie du pré-cadre et le tunnel de fenêtre. Il est ainsi possible d'obtenir un coefficient.Furthermore, the presence of the air insulation membrane makes it possible to give the window block (comprising the first part of the pre-frame and the second part of the pre-frame) good thermal insulation. The air that can penetrate from the outside is thus blocked by the membrane which extends between the second part of the pre-frame and the window tunnel. It is thus possible to obtain a coefficient.

L'élément isolant permet d'améliorer encore l'étanchéité à l'air du bloc de fenêtre. Cela est particulièrement vérifié lorsque l'élément isolant s'étend depuis la limite extérieure jusqu'à la limite intérieure du tunnel de fenêtre.The insulating element makes it possible to further improve the airtightness of the window block. This is particularly verified when the insulating element extends from the outer limit to the inner limit of the window tunnel.

De même, l'étanchéité est encore améliorée lorsque l'élément isolant s'étend sur toute la périphérie du pré-cadre.Similarly, sealing is further improved when the insulating element extends over the entire periphery of the pre-frame.

Avantageusement, la première partie du pré-cadre présente au moins une butée de positionnement du dormant sur le pré-cadre.Advantageously, the first part of the pre-frame has at least one abutment for positioning the frame on the pre-frame.

Dans ce cas, le dormant présente une fente destinée à recevoir la butée du pré-cadre.In this case, the frame has a slot intended to receive the abutment of the pre-frame.

La fente et la butée de positionnement permettent que la première partie du pré-cadre puisse être fabriquée en usine et qu'elle porte le dormant de la fenêtre dès sa sortie d'usine. L'installation in situ, c'est-à-dire sur le bâtiment à rénover, s'en trouve ainsi facilitée. En effet, le dormant de fenêtre est déjà positionné par rapport au mur, ce qui évite une opération de positionnement et de maintien du dormant préalablement à sa fixation sur le site de rénovation. Il est précisé qu'in situ, les conditions de travail et notamment les conditions de positionnement peuvent être difficiles voire précaires.The slot and the positioning stop allow the first part of the pre-frame to be manufactured in the factory and to carry the window frame as soon as it leaves the factory. Installation in situ, ie on the building to be renovated, is thus facilitated. Indeed, the window frame is already positioned in relation to the wall, which avoids an operation of positioning and holding the frame prior to fixing it on the renovation site. It is specified that in situ, the working conditions and in particular the positioning conditions can be difficult or even precarious.

Selon un mode de réalisation préféré, l'ensemble comprend des moyens de solidarisation conjointe du pré-cadre et du dormant au mur.According to a preferred embodiment, the assembly comprises joint securing means of the pre-frame and the frame to the wall.

La fixation du dormant et du pré-cadre se fait donc par le même moyen si bien que l'installation du bloc fenêtre est simple et rapide. Cela est notamment vérifié lorsque le dormant est déjà pré-positionné grâce à la butée de positionnement du pré-cadre et à la fente du dormant dans laquelle est reçue la butée de positionnement.The fixing of the frame and the pre-frame is therefore done by the same means so that the installation of the window unit is simple and quick. This is particularly verified when the fixed frame is already pre-positioned thanks to the positioning stop of the pre-frame and the slot in the fixed frame in which the positioning stop is received.

En outre, cette fixation est conçue pour procurer une rupture de pont thermique comme cela va être explicité plus en détails par la suite.In addition, this binding is designed to provide a thermal break as will be explained in more detail later.

La membrane d'isolation à l'air est solidaire du dormant.The air insulation membrane is attached to the frame.

La fixation de la membrane d'isolation au dormant permet d'assurer un bon positionnement de la membrane d'isolation lors de l'installation du pré-cadre dans le tunnel de fenêtre.Fixing the insulation membrane to the frame ensures correct positioning of the insulation membrane when installing the pre-frame in the window tunnel.

A cet effet, le dormant présente avantageusement une encoche périphérique dans laquelle est reçue une extrémité de la membrane d'isolation à l'air.To this end, the fixed frame advantageously has a peripheral notch in which one end of the air insulation membrane is received.

L'encoche périphérique assure une couverture périphérique complète par la membrane d'isolation.The peripheral notch ensures complete peripheral coverage by the insulation membrane.

Selon un mode de réalisation avantageux, la première partie du pré-cadre comprend une ceinture périphérique dans laquelle est destinée à venir s'intégrer une couche d'isolation thermique par l'extérieur solidaire du mur.According to an advantageous embodiment, the first part of the pre-frame comprises a peripheral belt in which is intended to be integrated a thermal insulation layer from the outside fixed to the wall.

L'intégration de la couche d'isolation thermique par l'extérieur dans la ceinture périphérique de la première partie du pré-cadre permet d'augmenter la qualité d'isolation du bloc de fenêtre. En effet, la couche d'isolation thermique par l'extérieur étant au contact de la première partie du pré-cadre, il n'existe pas de couloir de passage d'air entre la couche d'isolation par l'extérieur et le pré-cadre. L'air extérieur ne peut donc pas s'engouffrer dans le tunnel de fenêtre vers l'intérieur du bâtiment.The integration of the thermal insulation layer from the outside in the peripheral belt of the first part of the pre-frame makes it possible to increase the quality of insulation of the window unit. Indeed, the external thermal insulation layer being in contact with the first part of the pre-frame, there is no passageway for air between the external insulation layer and the pre-frame. -frame. The outside air can therefore not rush into the window tunnel towards the interior of the building.

Avantageusement, la première partie du pré-cadre porte peut intégrer un coffre de volet roulant.Advantageously, the first part of the door pre-frame can incorporate a roller shutter box.

Le coffre de volet roulant et le volet roulant qu'il contient peuvent participer à l'isolation à la fois thermique (en créant une zone d'air entre l'extérieur du volet roulant et la fenêtre) et lumineuse (en empêchant la lumière d'entrer dans le bâtiment lorsque le volet roulant est fermé).The roller shutter box and the roller shutter it contains can contribute to both thermal insulation (by creating an air zone between the outside of the roller shutter and the window) and light (by preventing light from entering the window). entering the building when the roller shutter is closed).

De préférence, la première partie du pré-cadre comprend un bord externe replié formant une gorge destinée à recevoir un profil de recouvrement formant un enjoliveur extérieur de l'ensemble.Preferably, the first part of the pre-frame comprises a folded outer edge forming a groove intended to receive a cover profile forming an outer trim of the assembly.

La finition de la rénovation peut être faite sur mesure par l'insertion dans la gorge du pré-cadre d'un profil de recouvrement, le profil de recouvrement pouvant notamment être interchangeable à souhait, par exemple en fonction de manifestations pour décorer le bâtiment.The finish of the renovation can be made to measure by inserting a covering profile into the groove of the pre-frame, the covering profile being able in particular to be interchangeable at will, for example according to events to decorate the building.

Il est à noter que la première partie du pré-cadre peut être démontée ultérieurement en cas de besoin sans dégrader l'ITE.It should be noted that the first part of the pre-frame can be dismantled later if necessary without degrading the ITE.

Tel qu'illustré sur la figure 1, un ensemble 1 selon l'invention comprend un pré-cadre 2 et un dormant 3 de fenêtre.As shown on the figure 1 , an assembly 1 according to the invention comprises a pre-frame 2 and a window frame 3.

L'ensemble 1 est destiné à être inséré dans un tunnel 4 de fenêtre d'un mur 5 de bâtiment.The assembly 1 is intended to be inserted into a window tunnel 4 of a wall 5 of a building.

Le bâtiment est notamment un bâtiment à rénover ou une construction neuve comprenant une couche d'isolation 6 par l'extérieur (ITE).The building is in particular a building to be renovated or a new construction comprising an insulation layer 6 from the outside (ITE).

La couche 6 d'isolation par l'extérieur est positionnée à l'extérieur du mur 5 et présente une ouverture qui définit avec une lumière du mur le tunnel 4 de fenêtre.The layer 6 of insulation from the outside is positioned outside the wall 5 and has an opening which defines with a light from the wall the tunnel 4 of the window.

Le pré-cadre 2 présente une première extrémité 2a située vers l'extérieur du bâtiment et une deuxième extrémité 2b située vers l'intérieur du bâtiment.The pre-frame 2 has a first end 2a located towards the outside of the building and a second end 2b located towards the interior of the building.

Le pré-cadre 2 est avantageusement réalisé par une tôle métallique pliée ou un assemblage de plusieurs tôles métalliques assemblées les unes aux autres pour former un fourreau s'étendant entre la première extrémité 2a et la deuxième extrémité 2b, et dans lequel est monté le dormant 3, le fourreau étant destiné à être inséré dans le tunnel 4 de fenêtre.The pre-frame 2 is advantageously produced by a folded metal sheet or an assembly of several metal sheets assembled together to form a sheath extending between the first end 2a and the second end 2b, and in which the frame is mounted. 3, the sheath being intended to be inserted into the tunnel 4 of the window.

En référence aux figures 1 et 2, le pré-cadre 2 comprend une première partie 21 dans laquelle est monté le dormant 3, et une deuxième partie 22 aboutées l'une à l'autre.With reference to figure 1 And 2 , the pre-frame 2 comprises a first part 21 in which the frame 3 is mounted, and a second part 22 butted to each other.

Plus précisément, la première partie 21 est destinée à être insérée dans le tunnel 4 de fenêtre par l'extérieur du bâtiment, et la deuxième partie 22 est destinée à être insérée dans le tunnel 4 de fenêtre par l'intérieur du bâtiment.More specifically, the first part 21 is intended to be inserted into the window tunnel 4 from the outside of the building, and the second part 22 is intended to be inserted into the window tunnel 4 from the inside of the building.

Pour permettre d'isoler l'intérieur du bâtiment de l'extérieur, la première partie 21 du pré-cadre 2 comprend une ceinture 23 périphérique dans laquelle est destinée à venir s'intégrer la couche 6 d'isolation thermique par l'extérieur solidaire du mur. La ceinture 23 périphérique s'étend depuis la première extrémité 2a vers la deuxième extrémité 2b.To make it possible to isolate the interior of the building from the exterior, the first part 21 of the pre-frame 2 comprises a peripheral belt 23 in which the layer 6 of thermal insulation from the exterior is intended to be integrated. from the wall. The peripheral belt 23 extends from the first end 2a towards the second end 2b.

Comme cela est visible sur la figure 1, la ceinture 23 périphérique forme, lorsque vue en coupe transversale, une encoche dans laquelle est reçue la couche 6 d'isolation par l'extérieur, cette encoche étant ouverte vers l'extérieur du tunnel 4 de fenêtre.As can be seen on the figure 1 , the peripheral belt 23 forms, when seen in cross section, a notch in which the layer 6 of insulation is received from the outside, this notch being open towards the outside of the tunnel 4 of the window.

L'isolation est également assurée par le fait que le pré-cadre 2 porte un élément 7 isolant sur sa périphérie.Insulation is also ensured by the fact that the pre-frame 2 carries an insulating element 7 on its periphery.

Plus particulièrement, chacune de la première partie 21 et de la deuxième partie 22 du pré-cadre 2 porte sur sa périphérie l'élément 7 isolant destiné à être intercalé entre le pré-cadre 2 et le tunnel 4 de fenêtre.More particularly, each of the first part 21 and of the second part 22 of the pre-frame 2 carries on its periphery the insulating element 7 intended to be inserted between the pre-frame 2 and the tunnel 4 of the window.

L'élément 7 isolant est par exemple une couche de polystyrène expansé (notamment connue sous ses initiales PSE) qui entoure chaque partie 21, 22 du pré-cadre 2 sur l'intégralité de sa périphérie.The insulating element 7 is for example a layer of expanded polystyrene (notably known by its initials PSE) which surrounds each part 21, 22 of the pre-frame 2 over its entire periphery.

Par ailleurs, toujours à des fins d'étanchéité, la première partie 21 du pré-cadre 2 comprend une membrane 8 d'isolation à l'air.Furthermore, still for sealing purposes, the first part 21 of the pre-frame 2 comprises a membrane 8 for air insulation.

La membrane 8 d'isolation forme également une barrière étanche à l'eau.The insulation membrane 8 also forms a waterproof barrier.

Tel qu'illustré sur les figures 1 et 2, la membrane 8 d'isolation à l'air est solidaire de la première partie 21 du pré-cadre, et plus particulièrement du dormant 3 de la fenêtre.As shown on the figure 1 And 2 , the air insulation membrane 8 is secured to the first part 21 of the pre-frame, and more particularly to the frame 3 of the window.

En référence à la figure 3, la membrane 8 d'isolation à l'air présentant une bande 81 périphérique souple destinée à être intercalée entre la deuxième partie 22 du pré-cadre et le tunnel 4 de fenêtre lorsque les deux parties 21,22 du pré-cadre 2 sont insérées dans le tunnel 4 de fenêtre.With reference to the picture 3 , the air insulation membrane 8 having a flexible peripheral strip 81 intended to be inserted between the second part 22 of the pre-frame and the window tunnel 4 when the two parts 21,22 of the pre-frame 2 are inserted in window tunnel 4.

Pour cela, le dormant 3 présente une encoche 31 périphérique dans laquelle est reçue une extrémité 82 de la membrane 8 d'isolation à l'air. L'extrémité 82 de la membrane 8 peut notamment être collée dans l'encoche 31 périphérique pour assurer un maintien de la membrane 8 sur la première partie 21 du pré-cadre 2.For this, the frame 3 has a peripheral notch 31 in which is received one end 82 of the membrane 8 for air insulation. The end 82 of the membrane 8 can in particular be glued in the peripheral notch 31 to ensure that the membrane 8 is held on the first part 21 of the pre-frame 2.

Pour faciliter l'assemblage du dormant 3 avec la première partie 21 du pré-cadre 2, la première partie 21 du pré-cadre 2 présente, à une extrémité 211 distale, opposée à la première extrémité 2a, au moins une butée 212 de positionnement du dormant 3.To facilitate the assembly of the frame 3 with the first part 21 of the pre-frame 2, the first part 21 of the pre-frame 2 has, at a distal end 211, opposite the first end 2a, at least one abutment 212 for positioning frame 3.

Plus précisément, la butée 212 est formée par repli de l'extrémité 211 distale vers l'intérieur du pré-cadre 2.More specifically, the abutment 212 is formed by folding the distal end 211 towards the inside of the pre-frame 2.

Le dormant 3 présente alors une fente 32 destinée à recevoir la butée 212 du pré-cadre 2.The frame 3 then has a slot 32 intended to receive the abutment 212 of the pre-frame 2.

Une pré-solidarisation du dormant 3 sur la première partie 21 du pré-cadre 2 peut être réalisée par des inserts 33 qui prennent en sandwich le pré-cadre 2 et une paroi du dormant 3. Les inserts 33 peuvent également être remplacés par des rivets.A pre-solidarisation of the frame 3 on the first part 21 of the pre-frame 2 can be carried out by inserts 33 which sandwich the pre-frame 2 and a wall of the frame 3. The inserts 33 can also be replaced by rivets .

Avantageusement, la pré-solidarisation du dormant 3 sur la première partie 21 du pré-cadre 2 est également réalisée par un bandeau de colle 34 entre le dormant 3 et la première partie 21 du pré-cadre 2.Advantageously, the pre-coupling of the fixed frame 3 on the first part 21 of the pre-frame 2 is also carried out by a band of glue 34 between the fixed frame 3 and the first part 21 of the pre-frame 2.

La solidarisation définitive du pré-cadre 2 avec le dormant 3 est réalisée par des moyens 35 de solidarisation conjointe du pré-cadre 2 et du dormant 3 au mur 5, comme décrit ci-après.The final attachment of the pre-frame 2 with the frame 3 is achieved by means 35 of joint attachment of the pre-frame 2 and the frame 3 to the wall 5, as described below.

Par ailleurs, le dormant 3 comprend un renfort 36 en aluminium logé à l'intérieur des profilés constituant le cadre du dormant 3.Furthermore, the fixed frame 3 comprises an aluminum reinforcement 36 housed inside the sections constituting the frame of the fixed frame 3.

Le dormant présente alors des perçages 37 réalisés conjointement dans le profilé et le renfort 36 pour permettre la pré-solidarisation du dormant 3 sur le pré-cadre 2 et la solidarisation de l'ensemble 1 au mur 5 par les moyens 35 de fixation.The frame then has holes 37 made jointly in the profile and the reinforcement 36 to allow the pre-fixation of the frame 3 on the pre-frame 2 and the fixing of the assembly 1 to the wall 5 by the means 35 of fixing.

Lors de l'installation, les perçages 37 débouchant à l'intérieur du dormant, c'est-à-dire visibles depuis l'intérieur du bâtiment, peuvent bouchés par des bouchons 38, tel qu'illustré sur la figure 4.During installation, the holes 37 emerging inside the frame, that is to say visible from inside the building, can be blocked by plugs 38, as illustrated in the figure 4 .

En référence à la figure 5, la première partie 21 du pré-cadre 2 comprend, à la première extrémité 2a, un bord 213 externe replié formant une gorge 214 destinée à recevoir un profil 9 de recouvrement formant un enjoliveur extérieur de l'ensemble 1.With reference to the figure 5 , the first part 21 of the pre-frame 2 comprises, at the first end 2a, a folded outer edge 213 forming a groove 214 intended to receive a covering profile 9 forming an outer trim of the assembly 1.

Avantageusement, la première partie 21 du pré-cadre 2 peut intégrer un coffre de volet roulant (non illustré) pour définir un ensemble permettant également une isolation lumineuse entre l'intérieur et l'extérieur du bâtiment.Advantageously, the first part 21 of the pre-frame 2 can incorporate a roller shutter box (not shown) to define an assembly that also allows light insulation between the inside and the outside of the building.

Lors de la fabrication en usine, le pré-cadre 2 est équipé de l'élément isolant 7. Plus précisément, chaque partie 21, 22 du pré-cadre 2 est formée puis reçoit, sur sa périphérie, l'élément 7 isolant. Le dormant 3 (de préférence avec un ouvrant qui lui est associé) est pré-solidarisé à la première partie 21 du pré-cadre 2.During factory production, the pre-frame 2 is equipped with the insulating element 7. More specifically, each part 21, 22 of the pre-frame 2 is formed and then receives, on its periphery, the insulating element 7 . The frame 3 (preferably with an opening associated with it) is pre-attached to the first part 21 of the pre-frame 2.

Lors de l'installation sur un bâtiment en rénovation, les installateurs peuvent insérer, par l'extérieur, la première partie 21 du pré-cadre 2 dans le tunnel 4 de fenêtre.During installation on a building under renovation, installers can insert, from the outside, the first part 21 of the pre-frame 2 into the tunnel 4 of the window.

Cette opération est avantageusement réalisée dans dépose de la menuiserie existante. Lorsque l'opération de rénovation est réalisée en hiver dans un bâtiment occupé, cela permet de conserver la chaleur à l'intérieur du bâtiment et d'éviter de créer de nombreux courants d'air rendant inutilisable le bâtiment.This operation is advantageously carried out without removing the existing carpentry. When the renovation operation is carried out in winter in an occupied building, this makes it possible to keep the heat inside the building and to avoid creating numerous drafts making the building unusable.

Lorsque la première partie 21 du pré-cadre est insérée dans le tunnel 4 de fenêtre, les installateurs peuvent extraite l'ancienne menuiserie par l'intérieur du bâtiment puis positionner la deuxième partie 22 du pré-cadre 2 dans le tunnel 4 de fenêtre.When the first part 21 of the pre-frame is inserted into the tunnel 4 of the window, the installers can extract the old carpentry from inside the building and then position the second part 22 of the pre-frame 2 in the tunnel 4 of the window.

L'insertion de la deuxième partie 22 du pré-cadre 2 dans le tunnel 4 de fenêtre permet que la membrane 8 d'isolation à l'air soit correctement agencé entre la deuxième partie 22 du pré-cadre 2 et le mur. En outre, tel qu'illustré sur la figure 2, lorsque la deuxième partie 22 du pré-cadre 2 est insérée dans le tunnel 4 de fenêtre, une extrémité intérieure de la deuxième partie 22 du pré-cadre 2 est positionnée entre le dormant 3 et le mur 5.The insertion of the second part 22 of the pre-frame 2 in the window tunnel 4 allows the air insulation membrane 8 to be correctly arranged between the second part 22 of the pre-frame 2 and the wall. Furthermore, as shown in the figure 2 , when the second part 22 of the pre-frame 2 is inserted into the window tunnel 4, an inner end of the second part 22 of the pre-frame 2 is positioned between the frame 3 and the wall 5.

La fixation définitive de l'ensemble 1 est alors effectuée par insertion des moyens 35 de solidarisation qui viennent en prise dans le mur 5. La pression exercée par les moyens 35 de solidarisation tend à plaquer les deux parties 21, 22 du pré-cadre 2 sur le mur 5, empêchant ainsi leur retrait par l'intérieur et l'extérieur du bâtiment.The final fixing of the assembly 1 is then carried out by inserting the securing means 35 which engage in the wall 5. The pressure exerted by the securing means 35 tends to press the two parts 21, 22 of the pre-frame 2 on wall 5, thus preventing their removal from inside and outside the building.

Pour finir l'installation, les installateurs positionnent le ou les plats 9 de recouvrement dans la ou chaque gorge 214 du pré-cadre 2, et les bouchons 38 sur le dormant 3.To complete the installation, the installers position the cover plate(s) 9 in the or each groove 214 of the pre-frame 2, and the plugs 38 on the fixed frame 3.

L'installation de l'ensemble selon l'invention permet donc une rénovation rapide et simple des ouvrants d'un bâtiment sur lequel une couche 6 d'isolation par l'extérieur a été ajoutée.The installation of the assembly according to the invention therefore allows quick and simple renovation of the openings of a building on which a layer 6 of insulation from the outside has been added.

Bien que la description concerne un bloc de fenêtre, l'ensemble 1 selon l'invention est adaptable à tout type d'ouvrant, notamment les portes et les baies coulissantes ou les baies fixes.Although the description relates to a window unit, the assembly 1 according to the invention is adaptable to any type of opening, in particular doors and sliding bays or fixed bays.
