Description

Domaine technique

[0001] The present invention relates to a connected insulating frame designed to receive a window or door frame and to create a connection with the exterior-mounted insulating wall. More specifically, the present invention relates to a connected insulating frame designed to be installed around an opening in a building wall, as an exterior-mounted element on the building's facade. The frame of the present invention is particularly suitable for being equipped with complementary equipment such as, for example, a roller shutter, hinged shutters, a blind / mosquito net, a balustrade, railings, an intrusion detector, or an alarm. Technique antérieure

[0002] It is known to use a one-piece subframe to install exterior joinery, such as windows, French doors in an opening made in a wall.

[0003] A building's wall typically consists of a structural wall, also known as the main structure, made of a hard material such as reinforced concrete, bricks, or concrete blocks, covered with a facing. In the case of exterior thermal insulation, an insulating layer made of an insulating material is sandwiched between the main structure and the facing.

[0004] State-of-the-art pre-frames consist mainly of metal profiles forming a rectangular frame whose dimensions are adapted to the dimensions of the opening.

[0005] To connect the structural frame to the window or door frame, the subframe can be fixed to the inside of the opening and anchored to the structural frame. The window or door frame is then attached to the subframe. Alternatively, the subframe can be fixed to the exterior of the structural frame, around the opening. The window or door frame is then attached to the subframe. Subframes are generally assembled on-site.

[0006] Regardless of the installation technique used for the subframe, it is necessary to carry out a multi-stage finishing process around it to both conceal the subframe and provide thermal insulation around both the subframe and the window / door frame. This process is tedious, time-consuming, and expensive. Furthermore, metal subframes promote thermal bridging with the building structure because they are directly exposed to the elements. In addition, they are difficult to adapt to existing buildings.

[0007] Furthermore, existing subframes are generally not equipped with a roller shutter box. This is often a separate component installed independently of the subframe, which complicates the overall installation. When the shutter is installed, the box is usually recessed into the upper part of the opening. This design reduces the glazed area and offers limited storage space. In addition, the fact that the interior of the box is exposed to outside air also contributes to thermal bridging. Moreover, accessing the housing to replace the shutter curtain or repair the drive mechanism in case of malfunction is difficult.

[0008] The housing can also be installed projecting from an interior side of the building, facing inwards. This configuration also does not provide optimal thermal insulation, and outside air can pass through, leading to drafts inside the building. Furthermore, the combined unit housing the shutter and the housing is unsightly.

[0009] Existing pre-frames do not offer the option of selecting exterior cladding in various shapes to enhance the building's architectural quality. Pre-frames for residential buildings have a similar exterior appearance to those for commercial buildings.

[0010] Finally, the existing subframes are not equipped with security systems to ensure the function of intrusion prevention and remote monitoring.

[0011] Document DE 298 09 053 U1 shows an insulating frame comprising a chassis forming a first rectangular frame and a facade composed of a load-bearing structure and a cladding.

[0012] The present invention aims to remedy the disadvantages of the prior art by proposing an insulating frame connected with an insulated roller shutter box, intended to cover the surroundings of an opening, designed to be installed easily and correctly while ensuring optimal thermal insulation of the building, significantly improving air tightness and reducing thermal bridges.

[0013] Another object of the invention is to propose a new insulating frame structure offering a larger box volume in order to be able to integrate one or more blackout systems such as a blind or a Venetian blind.

[0014] Another object of the invention is to offer an insulating frame with a removable finishing facade, making it possible to change the decoration after the installation of the subframe.

[0015] Another object of the invention is to provide an insulating frame which enables the function of anti-intrusion and remote monitoring, by equipping the frame with an intrusion detection system.

[0016] Another object of the invention is to offer an insulating frame allowing pre-assembly in the workshop to facilitate installation on site by easy assembly of the different prefabricated elements. Résumé

[0030] In the following description, terms relating to a position are taken in reference to a wall of a building.

[0031] With reference to figures 1 , 2A And 2B A building wall 2 with external thermal insulation typically comprises three layers: a structural layer 3, an insulating layer 4, and a facing layer 5. For example, the structural layer 3 can be made of reinforced concrete, brick, or any other material. The insulating layer is made of an insulating material such as expanded polystyrene, rock wool, wood fiber, or any other material. The facing layer 5 can be, for example, cladding or a layer of plaster.

[0032] On the figure 2A The terms "exterior" and "interior" refer respectively to the exterior and interior of the building.

[0033] The structural wall 3 has an opening 6 which here forms an opening to receive a window frame 7. In another example, the opening could be for a French door, a garage door, or any other type of window or door. As illustrated by the figure 2A , the frame of the joinery 7 is placed in a tunnel in the opening 6 of the structural wall 3.

[0034] There figure 2A shows an insulating frame 1 equipped with a roller shutter box 130 according to one embodiment of the invention. According to other embodiments, the insulating frame of the present invention can be equipped with a blind and a guardrail. In the example shown in the figure 1 , the insulating frame 1 includes in addition to an example of accessory 154, for example a guardrail.

[0035] The insulating frame 1 is arranged to protrude on a front face 3av of the structural wall 3 of the wall 2, facing outwards from the building.

[0036] The insulating frame 1 comprises a chassis 100 and a facade 200 assembled together.

[0037] The frame 100 comprises a rear face 100ar and a front face 100v. The rear face 100ar of the frame is applied against the perimeter of the opening 6 on a front face 3av of the structural wall 3 facing outwards from the building. The frame 100 is fixed to the structural wall 3 using the fixing elements 102.

[0038] With reference to figures 3A And 3B The façade 200 comprises a load-bearing structure 201 which is fixed to the front face 100av of the frame and a cladding 220. When the frame is installed, only the cladding 220 is visible from outside the building, as shown in the figure 1 .

[0039] The load-bearing structure 201 can be made of a rigid material resistant to atmospheric moisture, for example galvanized steel. The load-bearing structure 201 comprises an upper horizontal part 210, a lower horizontal part 270, and two lateral vertical parts 250 extending between the upper and lower parts, thus forming a rectangular frame 202.

[0040] The cladding 220 is made of thermally insulating material such as EPS, wood, or any other suitable insulating material. Advantageously, the material is chosen so that the shape can be custom-made to create an architectural decoration. A solar panel 214 is positioned on an inclined plane on the upper part of the cladding 220. The panel 214 is designed to power a battery 141 located in the housing 130.

[0041] Preferably, the cladding 220 is glued onto a front face 201av of the supporting structure 201.

[0042] The rear face 201ar of the facade's load-bearing structure 201 is equipped with a peripheral rim 204 positioned along its lower edge 270 and both vertical lateral edges 250. Thus, when the load-bearing structure 201 is positioned against the frame 100, the peripheral rim 204 encloses the edges of the frame. The peripheral rim 204 has a specific shape adapted to the type of facing panel that covers the wall's thermal insulation panel to ensure a perfect seal against rainwater. The facing panel can be, for example, a layer of plaster or cladding.

[0043] The lower horizontal part 270 of the load-bearing structure 201 of the facade 200 includes a notch 203 intended to receive the lower cross member 170 of the frame 100.

[0044] The rear face 201ar of the supporting structure 201 is further equipped with two continuous angle brackets 206 extending along the two lateral vertical parts 250, intended to secure the facade 200 to the frame 100 through fixing elements 254.

[0045] Preferably, the rear face 201ar of the supporting structure 201 of the facade 200 is also equipped with a set of receptacles 205 positioned on the lateral parts 250 for attaching, for example, a balustrade, railings, or hinged shutters. Advantageously, a thermal break is fixed in each receptacle 205. Thus, thermal break elements are interposed between the frame 100 and the facade 200.

[0046] According to the invention, when the frame 100 and the facade 200 are assembled together, the walls of the upper part of the facade 200 and that of the frame 100 define a housing to receive the roller shutter, and thus directly form a box 130 intended to receive a roller shutter, a blind, and other accessories.

[0047] The 130 box, which is an integral part of the insulating frame 1, is projecting from the structural wall 3, above the upper edge of the opening 6. Unlike a subframe in the prior art, the box does not reduce the area of ​​the opening, which defines the size of the bay. Furthermore, the 130 box is positioned partly below the insulating wall 4 and partly below the facing wall 5. Thus, when the structural wall 3 is covered by the insulating wall 4 and the facing wall 5, the front face 100av of the frame 100 is flush with the facing wall 5. The 130 box is therefore not visible from outside the building. Only the cladding 220 of the facade 200 protrudes beyond the exterior of the building, as in the construction example shown in the figure 1 When the insulating frame of the present invention is installed as illustrated in the figure 2A on a wall, the 130 box is made invisible when viewed from the front by the presence of the 200 facade. Such a construction prevents outside air from entering the building by passing through the roller shutter box.

[0048] Based on the implementation method illustrated on the figure 2A The window or door assembly includes, for example, a fixed frame 7 and a window sash, fitted with a pane of glass (not shown in the figure). The fixed frame 7 is tunnel-mounted in the opening 6 and rests against the inner edge of the insulating frame 1, which partially covers the perimeter of the opening 6. A weatherstrip is placed between the fixed frame and the insulating frame 1.

[0049] In another embodiment, the frame can be rebate-mounted in the insulating frame 1 and fully supported by the frame 100 of the insulating frame 1, such that the inner face of the frame 7 is aligned with the outer face of the structural wall 3. The frame 7 is fixed to the frame 100 by screwing through the inner perimeter of the frame, ensuring a perfect airtight seal. Fixing the frame by screwing through the frame allows the frame to be positioned inside the frame on rigid surfaces formed by the frame structure. The frame 7 is therefore installed without contact with the structural wall.

[0050] THE figures 4 And 5 respectively show an exploded view of the insulating frame of the invention from a view from outside the building and a view from inside the building.

[0051] The frame 100 is made of a rigid material resistant to atmospheric moisture, for example, galvanized steel. The frame 100 comprises a top rail 110, a bottom rail 170, and two side stiles 150. Each stile 150 extends between the top rail 110 and the bottom rail 170 to form a first rectangular frame 101 designed to rest, around the opening, against the front face 3av of the structural wall 3. The bottom rail 170 is covered by a drip edge 176. When the window or door frame is installed in the opening, the bottom of the frame 7 covers the inner edge of the drip edge 176 in order to channel rainwater away, as illustrated in the figure 2A .

[0052] The chassis 100 and the front face of the structural wall 3 include pre-drilled holes suitable for being positioned opposite each other for fixing the chassis to the front face of the structural wall by screwing through the holes with fixing elements 102.

[0053] The frame 100 and the supporting structure 201 of the facade 200 are assembled together by mechanical fastening elements 254 (visible on the figure 3B such as bolts screwed onto nuts. The load-bearing structure 201 is dimensioned to completely cover the chassis 100.

[0054] With reference to figures 6 à 12 The chassis 100 will be described in more detail below.

[0055] The side members 150 each have an exterior face 150ext and an interior face 150int. The top rail 110 has an exterior face 110ext and an interior face 110int. The bottom rail 170 has an exterior face 170ext and an interior face 170int. The exterior faces here refer to a face facing the thermal insulation layer 4 and the wall cladding 5 when the frame is installed around the opening, and the interior faces refer to the faces facing the opening.

[0056] The lower cross member 170 and the side members 150 are each fitted with a plurality of metal gussets to provide rigidity to the frame. For example, the outer faces 151ext of the side members 150 are each fitted with four metal gussets 151. The outer face 170ext of the lower cross member 170 is fitted with four metal gussets 171 positioned at regular intervals.

[0057] According to the invention, the frame 100 comprises peripheral support and fixing surfaces 132, 155, 175 for applying and fixing the frame 100 to the front face 3av of the structural wall 3 around the opening. The upper support and fixing surface 132 is formed by an internal vertical wall 132 located in the upper part of the frame 100. The lateral support and fixing surface 155 is formed by the gussets 151 of the side uprights. The lower support and fixing surface 175 is formed by the gussets 171 of the lower cross member 170. The support and fixing surfaces are each provided with pre-drilled holes 112 which are intended to be positioned opposite the pre-drilled holes made in the perimeter of the opening on the front face of the structural wall 3 for fixing the frame 100 to the front face of the structural wall through the holes.

[0058] The frame 100 further comprises, in its upper part, a horizontal wall 131 extending between the two lateral uprights 150. The two horizontal and vertical walls 131, 132, together with the lateral uprights 150, the upper cross member 110, and the upper part 210 of the load-bearing structure 201 of the facade 200, form a roller shutter box 130. Thus, the structure of the insulating frame of the present invention allows for the integration of a box while preserving the surface area for the shutter. Indeed, when the frame is installed on the front face of the structural wall 3, the box 130 protrudes from the front face of the structural wall and is not installed within the opening provided in the structural wall, as proposed in the prior art.

[0059] To access the inside of the roller shutter box, and in particular the roller shutter and its drive mechanism, the horizontal wall 131 is composed of a fixed horizontal wall 131F and a removable horizontal wall 131M which forms an access hatch. Thus, the box 130 includes an access opening to the box closed by the removable horizontal wall 131M. On the figure 8 The outer faces of the two walls 131F and 131M are each covered with a thermal insulation panel 185, 186. In addition, the box 130 also includes three thermal insulation panels 146, 147, 148 placed within the box. Panels 147, 148 are positioned against the sides of the lateral uprights and the vertical wall 132. The central panel 146 is positioned against the vertical wall 132, between the two panels 147, 148, as illustrated in the diagram. figure 11 .

[0060] The fixed horizontal wall 131F and the removable horizontal wall 131M are made of rigid material resistant to atmospheric moisture, for example galvanized steel.

[0061] The fixed horizontal wall 131F includes an external rim 133ext formed by a curved edge that extends along the longer side of the fixed wall 131F.

[0062] The access hatch formed by the removable wall 131M includes an inner rim 134int and an outer rim 134ext formed by curved edges extending along the two longest sides of the wall. These rims also serve to increase the rigidity of the walls.

[0063] The cabinet includes a hanging system for hanging the removable horizontal wall 131M on the fixed horizontal wall 131F and a fixing system for fixing the removable horizontal wall 131M to the side uprights 150.

[0064] The attachment system includes two inclined tabs 135F formed by the outer edge 133ext of the fixed wall 131F and two hooks 135M formed by the inner edge 134int of the movable wall 131M.

[0065] The fixing system comprises a horizontal L-shaped fixing bracket 136 and a locking element 138 arranged on the two shorter sides of the removable horizontal wall 131M, a lateral support 137 (visible on the figure 10 ) arranged on each side post 150.

[0066] When installing the access hatch formed by the removable panel 131M to close the opening of the shutter box 130, the two hooks 135M are positioned opposite the inclined sections 135F and hooked onto the inclined tabs 135F, while the fixing brackets 136 rest on the lateral supports 137 and are locked in position by the locking element 138, thus allowing the access hatch 131M to be fixed to the fixed horizontal panel 131F and the lateral uprights 150. The locking element 138 is, for example, a rotating cleat with an axis accessible from outside the box, and in particular from the outer face of an insulating panel fixed to the movable horizontal panel 131M. The end of the axis 138A is visible on the figure 8 .

[0067] It is therefore possible to release or lock the locking elements 138 in position relative to the lateral supports 137 by rotating the axis of the locking element a quarter turn with a suitable tool from outside the box 130.

[0068] Moving the removable partition 131M to access the inside of the housing 130 involves first rotating the axes 138A a quarter turn so that the locking elements 138 are no longer obstructed by the lateral supports 137. The movable partition 131M is then pushed upwards so that the hooks 135M are no longer engaged in the angled tabs 135F. The access hatch 131M is then moved horizontally outwards. Thanks to the combination of the fastening and hooking systems, moving the access hatch 131M requires several steps, thus ensuring its secure attachment to the housing 130.

[0069] Advantageously, the housing 130 includes two safety cables 139 screwed to the side uprights 150 at the junction with the ends of the movable wall 131M, to allow the access hatch 131M to be suspended when it is no longer attached to the housing 130. To be able to completely free the movable wall 131M, it is necessary to release the two safety cables 139 by unscrewing the nuts.

[0070] As is well known, a roller shutter typically has a curtain that can be moved between an extended position, in which the curtain covers a window, and a raised position, in which the curtain is rolled up and housed in the casing. To guide the movement of the curtain, the outermost free edge of each side stile 150 of the frame 100 is fitted with a guide rail 156.

[0071] Advantageously, the 156 slide is a double slide as illustrated on the figure 10 It is also possible to equip the frame with a blind.

[0072] Preferably, the outermost free edge of each side post 150 of the frame 100 includes a notch 157 to form a housing to receive the slides 156. Thus, when the inner face 150int of the side posts 150 is covered with a thermal insulation plate 184, the slides 156 are flush with the thermal insulation plate 184, forming a continuous surface.

[0073] Preferably, the insulating frame 1 includes thermal breaks 158 interposed between the tracks 156 and the inner faces of the side uprights 150 to limit thermal bridges.

[0074] In the lower part of the frame 100, the lower cross member 170 includes a front lip 173 and metal gussets 171. The number of metal gussets is not limited and is chosen according to the total mass of the insulating frame and any additional loads. The frame 100 also includes a drip edge 176 made of thermally insulating material that covers the lower cross member 170. The drip edge 176 has a drip profile 177 on its inner face.

[0075] In one embodiment, the insulating frame 1 includes an intrusion detection and remote monitoring system 140 placed in the roller shutter box 130 and connected to a wireless communication network, or wired if necessary. Thus, it is possible to activate it remotely.

[0076] The intrusion detection system includes, for example, a motion detector and / or a camera 140 mounted on the movable wall 131M. The intrusion detection and remote monitoring system is powered via a cable 145 by a battery 141 located in the housing 130. The battery 141 is, for example, powered by a solar panel 214 located on the upper part of the facade 200. More precisely, the solar panel 214 is located on an exterior face of the upper part of the cladding 220. The battery 141 is also used to power the shutter and / or blind mechanism.

[0077] According to another embodiment, battery 141 can also be connected to the building's electrical network if the electrical power supplied by the solar collector is insufficient for operation.

[0078] In an advantageous embodiment, the outer faces 150ext of the side posts 150 include fixing receptacles 152 for attaching an accessory 154, such as a balustrade, railing, or partition wall. Advantageously, each fixing receptacle 152 has a housing containing a threaded part made of a thermally insulating material 153.

[0079] With reference to the figure 11 The 130 box is partially shown, with the upper cross member 110, the rear vertical wall 132, and the fixed horizontal wall 131F. As shown in the figure 11The enclosure comprises three thermal insulation panels 146, 147, and 148 arranged within the enclosure 130. The central panel 146 is positioned between the vertical wall 132 and the longitudinal edge of the fixed horizontal wall 131F. The two panels 147 and 148, located on either side of the central panel, are affixed to the inner face of the side uprights. Furthermore, the outer faces of the access hatch 131M and the fixed horizontal wall 131F are also covered with thermal insulation panels 185 and 186, respectively.

[0080] According to the present invention, the frame structure of the present invention is particularly suitable for integrating thermal insulation plates so as to make the frame thermally insulating.

[0081] The different faces of the chassis 100 are covered with thermal insulation panels.

[0082] The frame 100 comprises two first lateral thermal insulation panels 181 fixed to the outer faces of each side member 150 of the frame 100, and a bottom thermal insulation panel 183 fixed to the outer face of the bottom rail 170. The thickness of the first lateral thermal insulation panels 181 is adjusted so that they are flush with the protruding surface formed by the notches 157 intended to receive the tracks. The insulating frame 1 may include two second lateral thermal insulation panels 182 covering the first lateral thermal insulation panels 181 and the areas of the side members not covered by the first thermal insulation panels. Thus, the outer perimeter edge of the frame is enveloped by the thermal insulation panels, allowing a perfect seal with the insulating wall 4.

[0083] The chassis 100 includes a moisture-resistant thermal insulation plate 176 intended to cover the front face of the lower cross member 170. The thermal insulation plate 176 is in the form of a sill with a water droplet profile 177 on its lower face.

[0084] The frame 100 includes two lateral thermal insulation plates 184 fixed to the inner faces of the side uprights 150 of the frame 100, a thermal insulation plate 186 fixed to the outer face of the fixed horizontal wall 131F and a thermal insulation plate 185 fixed to the outer face of the removable horizontal wall 131M. Thus, the inner peripheral edge of the frame is also completely covered by thermal insulation plates 176, 184, 185, 186.

[0085] The supporting structure 201 of the facade 200 comprises two lateral thermal insulation panels 281 fixed to the outer lateral edges of each side of the facade 200, a top thermal insulation panel 280 fixed to the outer edge of the upper section 210, and a bottom thermal insulation panel 283 fixed to the outer edge of the lower section 270. The outer perimeter edge of the supporting structure 201 of the facade 200 is thus enveloped by thermal insulation panels 280, 281, and 283. Preferably, the thermal insulation panel 283 of the lower section 270 has a drip edge profile. The inner perimeter edge of the supporting structure 201 of the facade 200 is also covered with thermal insulation panels 284, 285, and 286.

[0086] Wrapping the outside of the frame 100 and the facade 200 with thermal insulation panels eliminates the thermal bridge, unlike the conventional subframe which is generally monobloc and made entirely of metallic material in direct contact with the outside air, a source of thermal bridging.

[0087] The present invention is not limited to the examples and embodiments described and represented, it is susceptible of numerous variations within the scope of the annexed claims.
