Description

Title of the invention: JOINERY RECEIVING FRAME FOR A LIGHT-FRAME BUILDING, LIGHT-FRAME BUILDING EQUIPPED WITH AT LEAST ONE SUCH FRAME AND METHOD FOR ASSEMBLING SUCH A FRAME MANAGEMENT 1. Scope of the proposed technique

[0001] The field of the invention is that of light-framed buildings having, in the facade panels, bays for receiving joinery.

[0002] The invention relates in particular, for such light-framed buildings, to a frame for receiving joinery.

[0003] Such a framework finds numerous applications, in particular for buildings with a wooden frame or metal frame or other material with ventilated or non-ventilated cladding. 2. Prior art

[0004] Among the different types of buildings known, there are in particular those with a wooden frame. More precisely, there are those equipped with ventilated cladding or external insulation with added cladding.

[0005] A timber-framed building has a structure composed of panels comprising a wooden frame, formed of vertical uprights and horizontal crosspieces assembled together, insulation placed between the uprights of the frame and one or more boards attached to one of the faces.

[0006] Such panels, in particular those intended to form the cladding walls of the building (i.e. facade walls), also have a first sealing film, called a vapor barrier, applied to the inner face of the panel, and a second sealing film, called a rain barrier, applied to the outer face of this same panel.

[0007] Obviously, some of these facade panels have openings, also called bays, for receiving exterior joinery.

[0008] These exterior joinery pieces, whether they are, among others, windows, doors or French windows, generally comprise a fixed frame receiving one or more openings, opening inwards, and, where appropriate, one or more fixed panels.

[0009] The presence of such bays in the facade panels requires management of the sealing of the latter in order to ultimately ensure the sealing of the building as a whole.

[0010] To date, sealing is ensured, on the one hand, via the junction of the joinery to the bay and, on the other hand, via the addition of additional elements added before and / or after the installation of the joinery.

[0011] For example, a vapor barrier strip should be added at the opening and secured at one end using an adhesive. A wooden support should also be added to the lower wall of the opening on the lower side of the joinery. This support also ensures the junction of the sealing elements. The lateral and upper sides of the joinery are secured directly to the vapor barrier strips added to the side and upper walls. Finally, separate wooden edges are added to the side and upper walls of the opening to ensure a watertight junction between the exterior of the joinery and the exterior of the facade panel. The joinery thus provides a local injunction between the rain barrier and the vapor barrier of the panel.

[0012] Such a sealing solution has many disadvantages.

[0013] First of all, the effectiveness and durability of this solution is largely dependent on the level of mastery and skill of the operator who has to install the joinery and its sealing. For example, if the positioning and / or fixing of the additional vapor barrier strip is incorrect, the bay is not or only slightly sealed.

[0014] Mastering this solution is all the more complex as it requires several successive steps and the handling of different additional sealing elements (vapor barrier, adhesive, etc.). In addition, and significantly, the operator is regularly confronted with the use of additional sealing elements whose quality and / or intrinsic properties may vary, depending on the suppliers and / or manufacturers. These variabilities therefore require a good knowledge of the different sealing elements and a verification of their compatibility for effective implementation.

[0015] Furthermore, this waterproofing solution makes it impossible to replace the joinery and makes it difficult to correct the waterproofing in the event of a disaster, without causing further damage. Any major repair or replacement of joinery jeopardizes the initial waterproofing of the structure and the aesthetics of the window. A complete replacement of the waterproofing and connection elements between the joinery and the window is then necessary.

[0016] There is therefore a need to provide a technique for sealing the bays of light-framed buildings, particularly wooden ones, which do not have all or part of the disadvantages of the current solution. 3. Summary of the proposed technique

[0017] The proposed technique relates, according to a first aspect, to a frame for receiving joinery for a light-framed building, comprising four sides presenting respectively: - at least one first surface for bearing against a bay wall provided in the building; - at least one second surface, opposite the first surface, for receiving the joinery or an intermediate box; - a third surface, carried by a first projection of the first surface, for bearing against an exterior wall of the building; - a fourth surface, carried by a second projection of the second surface, for bearing against an external wall of the joinery or the intermediate box; - first sealing elements arranged at least partially opposite the first surface so as to ensure sealing between the frame and the bay wall; - second sealing elements arranged at least partially opposite the third surface so as to ensure sealing between the frame and the exterior wall of the building; and - third sealing elements arranged at least partially opposite the fourth surface so as to ensure sealing between the frame and the joinery or between the frame and the intermediate box.

[0018] A joinery reception frame according to the proposed technique thus makes it possible to easily and quickly ensure water and air tightness on the four sides of the bay. Such an arrangement also makes it possible to improve the thermal and sound performance of the bay.

[0019] According to another particular characteristic of the proposed technique, at least one of the sealing elements is produced in a single piece and extends on each of the four sides so as to form a closed loop.

[0020] Such an arrangement makes it possible in particular to guarantee the sealing of the corners of the bay and the frame. The continuity of the sealing elements makes it possible to avoid any weak areas in the sealing. This therefore results in particular in the significant longevity of the joinery installation.

[0021] According to another particular characteristic of the proposed technique, the frame is secured in a sealed manner to a concealment system box.

[0022] According to a particular characteristic of the proposed technique, the four sides of the frame have identical cross sections.

[0023] Alternatively, the frame comprises a side inside which the concealment system is housed.

[0024] Thus, a single operation of installing the frame makes it possible to ensure, in addition to sealing, the assembly of the joinery and the associated concealment system. As a result, it is possible to avoid additional steps and / or additional sealing elements to ensure the sealing of such joinery, relatively complex.

[0025] The proposed technique relates, according to a second aspect, to a light-framed building comprising at least one facade panel in which is provided at least one bay comprising at least one frame for receiving joinery as described previously.

[0026] The proposed technique relates, according to a third aspect, to a method of mounting a joinery receiving frame in a bay provided in a facade panel of a light-framed building. This mounting method comprises the following steps: - obtaining a carpentry reception frame as described previously; - positioning, from an exterior side of the facade panel, the frame in the opening so that all or part of the first sealing elements come into contact with a wall of the opening; and - inserting the frame into the bay until the second sealing elements come into contact with an external wall of the facade panel.

[0027] According to a particular characteristic of the proposed technique, the assembly method comprises a step of assembly of the joinery inside the frame carried out upstream or downstream of the steps of positioning and inserting the frame into the bay. 4. List of Figures

[0028] The proposed technique, as well as the various advantages that it presents, will be more easily understood, in the light of the following description of illustrative and non-limiting embodiments thereof, and of the appended drawings among which: - [Fig.l]: [Fig.l] illustrates, in a partial and schematic cross-sectional view, a timber-framed building equipped with a structural example of a joinery reception frame conforming to a first embodiment of the proposed technique; - [Fig.2]: [Fig.2] illustrates, in isolation, the carpentry reception frame of [Fig.l] so as to highlight the sealing elements; - [Fig.3]: [Fig.3] illustrates, in a partial and schematic cross-sectional view, an alternative implementation of such a frame, in accordance with the first embodiment, also receiving a concealment system box; and - [Fig.4]: [Fig.4] illustrates, in a partial cross-sectional view, a structural example of a joinery reception frame in accordance with a second embodiment of the proposed technique arranged in a bay of a timber-framed building.

[0029] 5. Detailed description of the proposed technique

[0030] For the sake of clarity, the same elements are designated by the same references in the different figures of the same embodiment. These same elements are designated by the same references in the different figures to which the symbol "'" is added incrementally between each embodiment.

[0031] Furthermore, the terms orientation and positioning are subsequently used with arbitrary reference to an installed position of the frame, when the latter is arranged inside a bay provided in a panel of a timber-framed building, and is oriented according to the plane of the panel (i.e. substantially perpendicular to the ground), so as to arrange substantially vertically a joinery to be received by said frame.

[0032] Obviously, a frame conforming to the proposed technique can be implemented in all types of light-framed buildings equipped with a rain screen (rigid or flexible), such as buildings with a metal frame or other materials with ventilated or non-ventilated cladding.

[0033] 5.1 General principle

[0034] The proposed technique therefore relates to a new sealing approach whose general principle is based on a frame for receiving joinery. This frame, intended to be arranged in a bay of a light-framed building, comprises four sides, each of which has a plurality of sealing elements with the joinery and, directly or indirectly, with the facade panel.

[0035] The proposed technique thus makes it possible to simply and effectively achieve definitive water and air tightness in a minimum of operations and components. This results in particular in a reduction in the time and difficulty of the operation of installing the joinery and sealing it.

[0036] Furthermore, a frame for receiving joinery in accordance with the proposed technique makes it possible to ensure the removal of the joinery, for the purpose of replacing it for example, without damaging the sealing of the bay.

[0037] The proposed technique also relates to a light-framed building comprising at least one frame for receiving joinery in accordance with the proposed technique.

[0038] The proposed technique further relates to a method of mounting such a frame in a bay provided in a light-framed building.

[0039] 5.2 Description of an illustrative embodiment

[0040] Figures 1 and 2 show an example of a joinery reception frame, according to a first embodiment of the proposed technique, arranged in a bay of a timber-framed building.

[0041] More specifically, [Fig.l] highlights in particular the usual structure of a facade panel of a timber-framed building inside which an equipped bay is provided of a carpentry reception frame. This frame is illustrated in isolation in [Fig.2].

[0042] Conventionally, a facade panel 2 of a timber-framed building comprises a wooden frame 21, an insulator 22, such as mineral wool, and one or more boards 23 attached to one face, intended to be oriented towards the outside preferably.

[0043] This facade panel 2 further comprises a first sealing film 24, called a vapor barrier, attached to the inner face of the facade panel 2, and / or a second sealing film 25, called a rain barrier, attached to the outer face of this same facade panel 2. Furthermore, in the example illustrated, ventilated cladding 26 is attached to the rain barrier 25 to ensure, from the outside, the thermal insulation of the facade panel 2.

[0044] In the facade panel 2 is provided a bay housing a frame 1 for receiving joinery 3.

[0045] This frame 1 comprises a rigid body 10 formed of four sides, of which only the lower side is shown, in a cross-section, for reasons of clarity.

[0046] According to the proposed technique, each side of the body 10 of the frame 1 comprises: - at least one first surface 110 intended to be placed in direct contact against a wall 210 of the opening (corresponding to the thickness of the panel) formed in the facade panel 2 of the timber-framed building; - at least one second surface 120, opposite the first surface 110, intended for receiving the frame 31 of the joinery 3 and for holding the latter in position; - a third surface 130, carried by a first projection 111 of the first surface 110, intended to be placed in abutment against an exterior wall 230 of the facade panel 2 of the timber-framed building; - a fourth surface 140, carried by a second projection 121 of the second surface 120, intended to be placed in abutment against an exterior wall 310 of the joinery 3.

[0047] Each side of the body 10 of the frame 1 further comprises: - first sealing elements 150 arranged opposite the first surface 110 so as to ensure sealing between the frame 1 and the bay wall 210; - second sealing elements 160 arranged opposite the third surface 130 so as to ensure sealing between the frame 1 and the outer wall 230 of the facade panel 2; and - third sealing elements 170 arranged opposite the fourth surface 140 so as to ensure sealing between the frame 1 and the exterior wall 310 of the joinery 3.

[0048] The installation (or assembly) of the frame 1 in the bay of the facade panel 2 is relatively simple because it is carried out in a single operation.

[0049] More precisely, the frame 1 is introduced into the opening from the outer side of the facade panel 2 until the second sealing elements 160 come into contact with the outer wall 230 of the facade panel 2. Simultaneously, the first sealing elements 150 come into contact with the wall 210 of the opening. At the end of this operation, the opening is watertight and airtight.

[0050] The frame 1 is then secured to the facade panel 2, by suitable means, in particular to lock the sealing of the bay.

[0051] The installation of the joinery 3 is carried out by introducing it from the interior side of the facade panel 2 until the third sealing elements 170 come into contact with the exterior wall 310 of the frame 31 of the joinery.

[0052] Alternatively, the joinery 3 can be installed in the frame 1 upstream. Thus, a single operation ensures the sealing of the bay and the installation of the joinery 3.

[0053] Such a joinery receiving frame thus makes it possible, via a single operation of installing it in the bay of the facade panel 2 described below, to ensure water and air tightness on the four sides of the bay. Such an arrangement also makes it possible to improve the thermal and sound performance of the bay.

[0054] Furthermore, in this embodiment, the four sides of the frame 1 are produced in the form of separate profiles and mechanically assembled. The body 10 of the frame 1 thus has a so-called continuous structure.

[0055] Such a continuous structure allows the body 10 of the frame 1 in particular to obtain an alignment of the surfaces 110, 130, 140 for receiving the sealing elements 150, 160, 170 respectively on each side.

[0056] Thus, each sealing element 150, 160, 170 can be formed by a single-piece sealing element, forming a loop, arranged on the periphery (internal or external) of the frame 1.

[0057] Such an arrangement is particularly interesting for guaranteeing the sealing of the corners of the bay and the frame.

[0058] [Fig. 3] shows, in a cross-sectional view, an alternative implementation of such a frame, in accordance with this first embodiment, also receiving a concealment system box.

[0059] This implementation variant is intended for window-type joinery for which a concealment system is provided. This is not necessarily the case for all windows in a building.

[0060] In other words, in this implementation variant the frame is tightly secured to a concealment system box.

[0061] In addition to the fact that such a variant allows the four sides of the frame to maintain identical cross-sections, it allows the proposed technique to be implemented with existing concealment systems.

[0062] More precisely, in this implementation variant, the body 10 of the frame 1 comprises an upper side 12.

[0063] In an identical manner to the three other sides (not shown) of the frame 1, this upper side 12 has:

[0064] - a first surface intended to be placed in direct contact against a wall 210 of bay provided in the facade panel 2; - a second surface 120, opposite the first surface 110; - a third surface, carried by a first projection 111 of the first surface, intended to be placed in abutment against an exterior wall 230 of the facade panel 2; - a fourth surface, carried by a second projection of the second surface 120.

[0065] This upper side 12, as well as an upper portion of each lateral side of the frame, are however distinguished by the fact that: - the second surface 120 is intended to receive a box 4 housing a concealment system 400, and

[0066] - the fourth surface is intended to come into contact with the box 4 of the system 400 occultation.

[0067] In such a case, an intermediate crosspiece 5, arranged between the box 4 of the concealment system 400 and the frame 31 of the joinery 3, is added in order to ensure sealing between these two devices.

[0068] Optionally, additional sealing elements can be added to the junction between the intermediate crosspiece 5 and the frame 1, more precisely on its lateral sides.

[0069] In the example illustrated, the intermediate crosspiece 5 comprises: - a first surface 510 for bearing against a box wall 4 of the concealment system 400; - a second surface 520, opposite the first surface 510, for receiving the frame 31 of the joinery 3; and - a third surface 530, carried by a projection 521 of the second surface 520, for bearing against an exterior wall 310 of the frame 31 of the joinery 3.

[0070] This third surface carries sealing elements (not shown) so as to ensure sealing between the intermediate crosspiece 5 and the joinery 3.

[0071] The intermediate crosspiece 5 and the frame 1, and their respective sealing elements, can be made of identical or different materials depending on requirements.

[0072] In this example, the intermediate crosspiece 5 has a slot (not referenced) for the passage of the concealment system 400 so as to allow its deployment and its storage.

[0073] 5.3 Another illustrated embodiment

[0074] [Fig.4] shows, in a cross-sectional view, an example of a joinery reception frame, according to a second embodiment of the proposed technique, arranged in a bay of a timber-framed building.

[0075] This second embodiment differs from the first embodiment essentially by the structure of the frame. For reasons of clarity and conciseness, the elements common and identical to the first embodiment are not described.

[0076] In this second embodiment, the upper side 12' of the body 10' of the frame houses the occultation system 400'.

[0077] Thus, the frame 1' and the concealment system 400' define a single-piece assembly.

[0078] A joinery receiving frame, in accordance with this second embodiment, makes it possible in particular to simplify the installation of a concealment system by integrating it directly into the frame of the proposed technique. Thus, a single operation of installing the frame makes it possible to ensure, in addition to sealing, the assembly of the joinery and the associated concealment system. Thus, it is possible to avoid additional steps and / or additional sealing elements to ensure the sealing of such relatively complex joinery.

[0079] In the illustrated example, the side 12' has an interior wall (not visible), defining an interior space in which the concealment system 400' is arranged. This side 12' also has a slot (not visible) opening into the interior space so as to allow the deployment and storage of the concealment system 400'.

[0080] 5.4 Other embodiments and variants not illustrated

[0081] In the illustrated embodiments, the receiving frame is made of a composite material. Obviously, any rigid material with intrinsically similar properties can be used. For example, a receiving frame made of a plastic material, such as polyvinyl chloride (PVC), or a metal material, such as aluminum, can be considered.

[0082] In the illustrated embodiments, the sides of the frame body are made in the form of separate profiles and mechanically assembled, where appropriate with the use of an additional sealing element between the mechanically fixed profiles. In an alternative embodiment, the frame body is made via a single profile, locally cut and hollowed out to ensure the connection and fixing, by welding for example, of the different sides.

[0083] In the illustrated embodiments, the sealing elements are made of a polymer material, such as Polyvinyl ethers (PVE) for example. Obviously, any flexible material intrinsically having similar sealing properties can be used, namely PVC, thermoplastic elastomers (TPE), ethylene-propylene-diene monomer (EPDM) rubbers, etc.

[0084] In another embodiment, not illustrated, the receiving frame comprises fourth sealing elements carried by the (second) receiving surface of the joinery. These fourth sealing elements make it possible to ensure, between the frame and the joinery, vapor tightness. Such a configuration makes it possible to further improve the tightness provided by the frame.

[0085] In certain illustrated embodiments, the body of the frame has a so-called continuous structure in order to allow the sides to have identical cross-sections. In at least one other embodiment, not illustrated, the body of the frame is formed from several profiles having different cross-sections. For example, to allow the passage of a screening element. These variations in cross-sections may result from the initial structures of the profiles and / or from machining operations carried out on these profiles.

[0086] Obviously, the proposed technique is not limited to the embodiments described above and provided solely as an example. It encompasses various modifications, alternative forms and other variants that may be envisaged by those skilled in the art within the framework of the proposed technique and in particular all combinations of the different embodiments described above, which may be taken separately or in association.

[0087] According to different aspects, the proposed technique therefore presents all or part of the following advantages, depending on the embodiments and / or variants chosen:

[0088] - guarantee the overall sealing of the bay;

[0089] - simplify the bay sealing operations;

[0090] - ensure the removal / replacement of the joinery without damaging the sealing of the bay ;

[0091] - offer a versatile solution, adaptable to system boxes of occultation,

[0092] - guarantee significant longevity;

[0093] - improve the thermal performance of the bay;

[0094] - improve the acoustic performance of the bay;

[0095] - etc.
