Description

Title of the invention: Bay frame component

[0001] The present invention relates to a window frame component, a construction incorporating such a component and a method for manufacturing such a component.

[0002] It relates more particularly to a window frame component, such as a window sill or door threshold, said component comprising a plate equipped with two opposing lateral edges, a rear edge, called the rear drip edge, opposite the front edge of the plate, the rear drip edge and the lateral edges each having an internal longitudinal flank, an external longitudinal flank and a top, and delimiting, with the face, called the top of the plate bordered by said edges, a water collection tray and a water guidance system beyond the front edge of the plate, said component being of the type insertable between masonry jambs called jambs intended to be covered with a layer of plaster and having a jamb dimension, excluding plastering, of known value,said part further comprising at least two tabs extending at least in line with the rear edge and a thermally insulating coating forming with the plate and said tabs a single prefabricated assembly, said coating covering at least partially the underside and rear edge of the plate, at least part of which is formed by the outer longitudinal side of the rear sill.

[0003] Window and door frame components are well known to those versed in this art. Such frame components, positioned against the lower edge of a structure to define the lower edge of the opening constituting the window or door, are generally designed to receive the lower rail of the fixed frame of a window or other joinery that closes the opening, and to provide a drainage element for rainwater projected onto the windows or falling on the part of the facade wall corresponding to the window or door opening. Such a component has a slightly raised rear portion that acts as a stop for the lower rail of the fixed frame of the joinery and generally extends across the entire width of the exterior wall, projecting from the facade.For a long time, window and door frames required cutting into the masonry at the window and door reveals to allow their insertion into the opening. More recently, frames that fit between the window and door reveals have appeared on the market, as illustrated by patent FR-2,930,585. These frames are characterized by their ease of installation. However, new thermal regulations now require the use of thermally broken frames. Such frames are also known from the prior art, as illustrated in particular by patent FR-2,966,187, but in a different version. corresponding to versions requiring anchoring or cutting into the masonry for installation. At the same time, solutions are being sought to reduce the carbon footprint of a building without compromising its thermal insulation properties.

[0004] An object of the present invention is to propose a frame piece whose design makes it possible to reduce the carbon footprint of the construction comprising at least one such frame piece without harming the elimination or reduction in an effective manner of the presence of thermal bridging or the ease of manufacture and assembly of said frame piece in the bay and / or the installation of the joinery on said piece.

[0005] Another object of the present invention is to provide a frame piece whose design allows limiting the amount of insulation to be used without compromising the safety of the assembly in terms of insulation and limiting or eliminating thermal bridges, nor the ease of installation.

[0006] To this end, the invention relates to a window frame component, of the type window sill or door threshold, said component comprising a plate equipped with two opposing lateral edges, a rear edge, called the rear sill, opposite the front edge of the plate, the rear sill and the lateral edges each having an internal longitudinal flank, an external longitudinal flank and a top, and delimiting, with the face, called the top of the plate bordered by said edges, a water collection tray and guiding the water beyond the front edge of the plate, said component being of the type insertable between masonry jambs called jambs intended to be covered with a layer of plaster and having a jamb dimension, excluding plastering, of known value,said part further comprising at least two lugs extending at least in line with the rear edge and a thermally insulating coating forming with the plate and said lugs a prefabricated unit in one piece, said coating covering at least partially the underside and rear edge of the plate, at least part of which is formed by the outer longitudinal side of the rear edge, characterized in that the lugs, which are thermally insulating lugs, are made at least partially of a thermally insulating material forming at least the visible outer surfaces of the lugs, in that the lugs and the thermally insulating coating are arranged contiguously, and in that the thermally insulating material of the lugs and the thermally insulating coating of the underside and rear edge of the plate each comprise at least cork.

[0007] Thanks to the fact that the ears extend at least in line with the rear edge, said ears extend beyond each side of the panels. Thus, the side edges extend between the panels while the ears come into support on the inner wall of the building in the inserted state of the room between the said panels.

[0008] The production of tabs, at least the visible outer surfaces of which are made of a bio-based thermally insulating material of the same nature as the thermally insulating cladding, allows, in combination with the thermally insulating cladding, for a thermal break with a reduced carbon footprint without compromising the ease of installation of the frame. The fact that the tabs and the thermally insulating cladding are arranged contiguously, i.e., touching, ensures, due to the nature of the tabs, continuity of thermal insulation. Thus, insulation is provided at the rear, sides, and underside of the frame. The cork-based nature of the thermal insulation allows for insulation with low thermal conductivity, a low carbon footprint, and water tightness.Thanks to this type of frame, the frame is embedded within the opening from inside the building. The fact that the frame does not penetrate the masonry ensures compliance with seismic regulations.

[0009] According to the embodiment of the invention, the thermally insulating material of the ears also forms the interior, referred to as the core of the ears, each of which is in the form of a monolithic block that can be cut. Due to the nature of the thermally insulating material, it is easily cut. This cutting capability allows the setback distance of the frame piece towards the interior of the building to be varied. The monolithic block that can be cut thus allows the setback of the first piece to be adjusted when inserted between the window and door frames.

[0010] According to one embodiment of the invention, the thermally insulating coating of the underside and rear edge of the plate is formed of several elements. Alternatively, the thermally insulating coating can be made of a single piece.

[0011] According to one embodiment of the invention, the thermally insulating coating, which at least partially covers the underside of the plate, extends beyond the outer longitudinal edge of each lateral rim, over at least a portion of the length of said lateral rim, to form a contact surface with a tab. This design facilitates continuous thermal insulation.

[0012] According to one embodiment of the invention, the thermally insulating coating, which at least partially covers the underside of the plate, protrudes from the outer longitudinal side of the rear drip edge to form a contact surface with a portion of the thermally insulating coating, which at least partially covers the rear edge of the plate. Again, this design facilitates continuous thermal insulation.

[0013] According to one embodiment of the invention, the thermally insulating coating covering at least part of the rear edge of the plate protrudes from the outer longitudinal side of each of the lateral edges to form a contact surface with an ear.

[0014] According to one embodiment of the invention, the thermally insulating coating extends, over at least part of the length of the rear sill, beyond the top of the rear sill and protrudes from the top or upper face of the rear sill by a value preferably of at least 1 mm. Thus, the joinery rests on the thermally insulated part of the frame piece.

[0015] According to one embodiment of the invention, the ears extend, over at least part of their length, beyond the top of the lateral edges and protrude from the top or face of the top of the lateral edges by a value preferably of at least 1 mm.

[0016] According to one embodiment of the invention, the plate is made of concrete and the cork is preferably natural cork. The concrete is preferably a low-carbon, high-performance, high-density fine concrete.

[0017] According to one embodiment of the invention, the portion of the thermally insulating coating in contact with the underside or rear edge of the plate forms a non-smooth surface to allow the concrete to be anchored in said portion. In other words, the portion of the thermally insulating coating in contact with the underside or rear edge of the plate has a roughness greater than that of the underside or rear edge of the plate.

[0018] According to one embodiment of the invention, at least a portion of the top of the lateral or rear edges of the plate forms a non-smooth surface. This results in easier adhesion of the coating.

[0019] According to one embodiment of the invention, a portion of the thermally insulating coating is in direct contact with the underside or the rear edge of the plate, said constituent material of the plate acting as a binder for the thermally insulating coating to the plate, to the exclusion of any other binder. Preferably, the underside of the plate has a stepped surface defining a recess into which the thermally insulating coating is inserted.

[0020] The invention further relates to a construction of the type comprising a bay delimited by an upper edge, two panels, and a lower edge formed by a frame piece insertable between the panels of the bay, characterized in that the frame piece is of the aforementioned type.

[0021] In the inserted state of the frame piece between the bay windows, each outer longitudinal side of a lateral edge is separated from said window by a gap forming an air gap. Preferably, the air gap is at the level of the top of the The side edge is insulated from the outside by a sealant, such as polyurethane sealant. The window frame rests on its lower rail on the overhanging portion of the thermally insulating cladding, that is, the portion extending beyond the top of the rear sill. This portion of the cladding thus forms a bearing surface extending to a higher level than the top face of the rear sill.

[0022] According to one embodiment of the construction, the overall width of the frame piece taken at the level of the side edges and corresponding to the distance between the external longitudinal sides of the side edges is less than the dimensions of the tables.

[0023] The invention further relates to a method of manufacturing a frame piece of the aforementioned type, using a mold, characterized in that it comprises a step of introducing into the mold the ears and the thermally insulating coating in the form of a prefabricated structure in one or more parts and a step of pouring into the mold the material constituting the plate. Brief description of the drawings

[0024] The invention will be better understood upon reading the following description of exemplary embodiments, with reference to the accompanying drawings in which:

[0025] [Fig. 1] represents a perspective view of a framing piece according to the invention suitable for forming a threshold or a window sill;

[0026] [Fig.2] represents an exploded view of the constituent elements of a frame piece according to the invention and a mold suitable for use in the manufacture of such a frame piece;

[0027] [Fig.3] represents a partially cross-sectional view of a frame piece according to the invention;

[0028] [Fig.4] represents a cross-sectional view of a frame piece according to the invention;

[0029] [Fig.5] represents a partial perspective view of a bay of a construction in the positioned state of a framing piece according to the invention in said bay;

[0030] [Fig.6] represents a schematic partial view in transparency of a construction in the positioned state of a frame piece according to the invention in said bay.

[0031] As mentioned above, the invention relates to a frame piece 1 that can be inserted between the frames 11 of a bay 10 to form the lower edge of said bay, also delimited by an upper edge and two frames 11. These frames 11 are, prior to the coating of a plaster, separated from each other by a known predetermined distance called the frame dimension.

[0032] The frame piece 1 comprises a plate 2, generally monolithic, preferably made of concrete, in particular of high-performance, high-density, low-carbon fine concrete. This plate 2, which may also be made of a material other than the Concrete, such as a composite material, comprises a front edge 23 and a rear edge 24, a top face 21 and an opposite bottom face 22. This plate 2 is equipped with two opposing lateral edges 3 and a rear edge 4, called the rear rim 4, opposite the front edge 23 of the plate 2.

[0033] The rear sill 4 comprises an internal longitudinal flank 41, i.e. turned towards the center of the plate 2, an external longitudinal flank 42 opposite the internal longitudinal flank 41 and a vertex 43 forming the top face of the sill 4. Similarly, each lateral rim 3 comprises an internal longitudinal flank 31, an external longitudinal flank 32 opposite the internal longitudinal flank 31 and a vertex 33 forming the top face of the lateral rim 3. The rear sill 4, in particular the internal longitudinal flank 41 of the rear sill and the lateral rims 3, in particular the internal longitudinal flanks 31 of the lateral rims 3, together with the face 21 of the top of the plate 2 bordered by said rims 3 and 4, define a water collection and water guidance tray beyond the front edge 23 of the plate 2. The bottom of the tray is inclined from rear to front to facilitate the flow of water.

[0034] Ideally, this base has, from the rear edge 24 to the front edge 23 of the plate 2, a first inclined surface, then a second inclined surface, as illustrated in [Fig. 4], the slope of the first inclined surface being greater than the slope of the second inclined surface. The frame piece 1 is insertable between the panels 11, so that the lateral edges 3 each extend vertically below the layer of plaster covering a panel. The front edge 23 of the plate 2 generally projects from the structure, as illustrated in [Fig. 5]. This frame piece 1 can form a threshold or a sill.

[0035] The plate 2 further includes lugs 6 at its rear edge, at least part of which is formed by the outer longitudinal flank 42 of the rear sill 4 in line with said rear edge 4. These lugs 6 extend inside the structure, bearing against the inner face of the wall of said structure.

[0036] The frame piece 1 further comprises a thermally insulating coating 5 which, together with the plate 2 and the lugs 6, forms a prefabricated, one-piece assembly. This coating 5 overlaps at least partially the underside face 22 and the rear edge 24 of the plate 2, and preferably extends beyond the top 41 of the rear edge 4, as can be seen in [Fig. 3].

[0037] Ideally, the thermally insulating coating 5 extends over at least part of the length of the rear sill 4, projecting beyond the apex 43 of the rear sill 4 and extending beyond the apex 43 or the top face of the rear sill 4, preferably by a value of at least 1.5 mm. The thermally insulating coating 5 comprises at least cork. Preferably, the cork is natural cork. The coating 5 thermally insulating material has a variable thickness depending on the type of wall insulation.

[0038] Generally, and as illustrated in [Fig. 2], the thermally insulating coating 5 on the underside face 22 and the rear edge 24 of the plate 2 is formed of several elements. In the example shown, this thermally insulating coating 5 takes the form of two panels, one of which is positioned on the underside face 22 of the plate 2, and the other is applied to the rear edge 4 of the plate 2, part of which is formed by the external longitudinal side 42 of the rear sill 4.

[0039] At the level of the face 22 of the underside of the plate 2, the latter has a stepped surface delimiting a recess inside which the coating 5 is inserted.

[0040] In the examples shown, the thermally insulating coating 5 partially covering the underside face 22 of the plate 2 protrudes from the outer longitudinal side 42 of the rear sill 4 to form a surface in contact with a part of the thermally insulating coating 5 at least partially covering the rear edge 24 of the plate 2, as can be seen in [Fig. 1].

[0041] Similarly, the thermally insulating coating 5, which at least partially covers the underside face 22 of the plate 2, extends beyond the outer longitudinal side 32 of each lateral edge 3 over at least part of the length of said lateral edge 3 to form a surface in contact with an ear 6.

[0042] In the examples shown, the thermally insulating coating 5, which at least partially covers the rear edge 24 of the plate 2, protrudes from the external longitudinal side 32 of each of the lateral edges 3 to form a contact surface with an ear 6. It is noted that the part of the thermally insulating coating 5, in contact with the face 22 of the underside or the rear edge 24 of the plate 2, forms a non-smooth surface to allow the anchoring of the concrete constituting the plate 2 in said part.

[0043] In other words, the portion of the thermally insulating coating 5 in contact with the underside face 22 or the rear edge 24 of the plate 2 has a roughness greater than that of the underside face or the rear edge of the plate. Similarly, at least a portion of the top 33, the lateral edges 3, or the rear edge 43 of the plate 2 forms a non-smooth surface to allow for the coating to adhere. A portion of the thermally insulating coating 5 is in direct contact with the underside face 22 or the rear edge 24 of the plate 2, the constituent material of the plate 2 acting as a binder for the thermally insulating coating 5 to the plate 2, to the exclusion of any other binder. This is observed when the frame piece 1 is manufactured by molding with the thermally insulating coating 5, forming an insert in the mold, such as the lugs 6. These lugs 6 are thermally insulating lugs.These 6 ears are at least partially realized. made of a thermally insulating material forming at least the visible outer surfaces 61 of the ears 6. The ears 6 and the thermally insulating covering 5 are arranged contiguously. The ears 6 and the thermally insulating covering 5 may be made in one piece or in several elements. The thermally insulating material of the ears 6 and the thermally insulating covering 5 of the underside 22 and the rear edge 24 of the plate 2 each comprise at least cork and are preferably made of identical composition.

[0044] In the examples shown, the thermally insulating material of the ears 6 also forms the interior, referred to as the core 62, of the ears 6, each of which is in the form of a monolithic, cuttable block. The thermally insulating material constituting the ears, which includes cork, is preferably formed from a block of natural or recycled material. Preferably, the cork used is a high-density natural cork, for example with a density of approximately 200 kg / m³. These ears 6, generally parallelepiped in shape, rest on one of their faces, referred to as the first face, on the portion of the thermally insulating coating 5 that overlaps the rear edge of the plate 2, and on another face, referred to as the second face adjacent to the first face, on the portion of the thermally insulating coating 5 that at least partially overlaps the underside of the plate 2.The face of the ear opposite the first face is designed to bear against the vertical wall of the structure adjoining the opening 10. Each ear 6 is applied by one of its faces to the outer longitudinal side of a lateral edge. Thus, the ears 6 and the thermally insulating cladding 5, arranged contiguously, form a frame around the rear edge, part of the underside, and the sides of the plate 2, ensuring continuous thermal insulation. The possibility of cutting the ears 6 at the face intended to bear against a vertical wall of the structure allows the setback distance of the framing piece within the structure to be varied.

[0045] Ideally, the lugs 6 extend at least part of their length beyond the apex 33 of the lateral edges 3 and protrude from the apex 33 or the top face of the lateral edges 3 by a value preferably of at least 1 mm. The thermally insulating coating 5 and the lugs 6, when made of several elements, can be joined by gluing. This assembly can be inserted into the mold 12 before casting the plate 2.

[0046] Indeed, for the manufacture of such a part, the following procedure is followed. The ears 6 and the prefabricated coating 5 made in one or more parts are introduced inside a mold and the constituent material of the plate 2, in this case concrete, is poured into the mold.

[0047] To install a window sill, the following procedure is used. The recessed piece is inserted between the jambs, as illustrated in Figures 5 and 6, with the tabs 6 bearing against the wall inside the structure. When part of the piece is inserted between the jambs, an air gap is created between the outer longitudinal edge of each lateral rim and the opposite jamb. This air gap is sealed with a sealant. The window frame, such as a window, is installed on the facing portion 5 that overhangs the rear sill 4, or according to an installation method specific to each manufacturer. The jambs are then plastered. A sill is installed in a similar manner. Naturally, a sealant is also provided between the bearing surface of the tabs on the interior wall of the structure and the interior wall itself.
