Description

Title of the invention: shock absorber system for insulating glazing on wall

[0001] The invention relates to a structure comprising a wooden wall and insulating glazing. The invention further relates to a method of assembling said structure.

[0002] A structure, such as a building wall, comprising an insulating glazing unit and a frame is known from the prior art. The frame constitutes an intermediate element between the structure and the insulating glazing unit. Generally, the frame is first installed in a suitable opening in the structure, and then, subsequently, the insulating glazing unit is inserted into it. In an alternative installation, the insulating glazing unit is inserted into the frame, and then the assembly is inserted into the suitable opening in the structure. Such a structure has the disadvantage of a complex and lengthy installation. It is estimated that its assembly requires approximately two hours and the intervention of two qualified people. In addition, the method requires the use of various installation elements, the management of the supply of these elements and the management of a stock of insulating glazing units.

[0003] To overcome these drawbacks, there is a wooden structure having a first face and a second face, a wall and an opening, said opening being arranged between the first and second faces, the structure comprising an insulating glazing, said insulating glazing comprising at least a first pane and a second pane arranged substantially parallel to each other, said insulating glazing having a first face and a second face, remarkable in that the structure comprises an adhesive joint binding the insulating glazing and the wall.

[0004] The disadvantage of the absence of a frame is that the latter also acts as a buffer means. Indeed, the frame is such that it isolates the glazing from the external environment such as vibrations.

[0005] Thus, a glazing mounted, without a frame, on a wall is more sensitive to the external environment. During a meteorological episode with wind, the latter exerts stress on the glazing. Summary of the invention

[0006] The aim of the invention is therefore to overcome the drawbacks of the prior art by proposing a structure comprising insulating glazing that is simple and quick to implement, as well as its installation method.

[0007] To this end, the invention relates to a structure having a first face and a second face, a wall and an opening, said opening being arranged between the first and second faces, the structure comprising insulating glazing, said insulating glazing comprising at least a first pane and a second pane arranged in possibly parallel to each other, said insulating glazing having a first face and a second face, the structure comprising an adhesive joint bonding the insulating glazing and the wall, characterized in that the structure comprises damping means between the insulating glazing and the wall.

[0008] According to one example, the damping means comprise at least one strip made of elastically deformable material.

[0009] According to one example, the strip made of elastically deformable material has a straight or L-shaped or U-shaped section.

[0010] According to one example, the strip made of elastically deformable material is glued or screwed or overmolded to the glazing.

[0011] According to one example, the damping means comprise at least one profile assembled to the glazing, said profile comprising at least one damping element, and in that said glazing is fixed to the wall by means of the profile.

[0012] According to one example, said damping element is a pad made of elastic material.

[0013] According to one example, said damping element is a spring.

[0014] According to one example, said damping element is arranged between the glazing and the profile.

[0015] According to one example, said damping element is arranged between the profile and the wall.

[0016] According to an example, the opening comprises a first cleat, a second cleat, a third cleat, the glue joint being arranged between the cleats and the insulating glazing.

[0017] According to one example, the structure comprises a glazing bead arranged in contact with the first face of the insulating glazing and at least one fixing element passing through the glazing bead and fixing in the wall, the second face of the insulating glazing being in contact with the first face of the structure.

[0028] In the embodiment(s) of the invention, an insulating glazing unit comprising panes or sheets of glass is described. Each pane may be monolithic, i.e. made up of a single sheet of material, or be composite, i.e. made up of several sheets of material between which is inserted at least one intermediate layer of adherent material, in the case of laminated glazing units. The sheet(s) of material may be mineral, in particular made of glass, for example having undergone annealing or tempering, or organic, in particular made of plastic such as polyvinyl butyral. The intermediate layer preferably contains at least one thermoplastic plastic, preferably polyvinyl butyral (PVB), ethylene vinyl acetate (EVA), and / or polyethylene terephthalate (PET).However, the thermoplastic intermediate layer may also contain, for example, polyurethane (PU), polypropylene (PP), polyacrylate, polyethylene (PE), polycarbonate (PC), polymethyl methacrylate, polyvinyl chloride, polyacetate resin, casting resins, acrylates, fluorinated ethylene-propylene, polyvinyl fluoride and / or ethylene-tetrafluoroethylene, or copolymers or mixtures thereof. The thermoplastic intermediate layer may be formed from one or more superimposed thermoplastic films.

[0029] [Fig.l] illustrates a sectional view of a structure 1 according to a first embodiment of the invention. The structure 1 comprises a wall 2 having an opening 3 of substantially rectangular shape. In an alternative, the opening 3 is substantially square in shape. The structure 1 can be made of wood or metal or concrete.

[0030] The structure 1 further comprises an insulating glazing unit 4 comprising two sheets of glass, also called panes, used to thermally and acoustically insulate the interior of a building in which the insulating glazing is intended to be installed from the outside. Such insulating glazing 4 is referred to by various names such as double glazing, double-glazed window, or IGU, an acronym meaning Insulated Glazing Unit in English.

[0031] The panes of the insulating glazing 4 may be, for example, monolithic glass sheets having a thickness of between 2 and 6 mm. It may also be an assembly of two glass sheets adhesively bonded by a lamination interlayer, for example made of polyvinyl butyral, also known by the acronym PVB. This assembly makes it possible to give the pane anti-burglary and / or acoustic insulation and / or personal safety properties, for example anti-breakage. The faces of the panes may be coated with stacks of thin layers giving the insulating glazing 4 various functionalities.For example, the outer face of the panes may be coated with a self-cleaning stack containing at least one photocatalytic layer, in particular titanium oxide, in particular at least partially crystallized in anatase form, and / or an anti-condensation stack comprising at least one low-emissivity layer such as a layer of a transparent conductive oxide (TCO), in particular indium tin oxide (ITO) or doped zinc oxide. The other faces of the panes may be coated with stacks of low-emissivity thin layers comprising at least one layer of silver. The panes are fixed to a spacer extending continuously along their edges. The spacer has, in particular, the function of arranging an air gap between the two panes. The air gap thus makes it possible to create thermal insulation. The cold wall effect is reduced, allowing a reduction, or even disappearance, of condensation.In winter, heat loss is reduced, and in summer, heat transfer from the outside to the inside of the building is limited. This makes the building's air conditioning system more energy-efficient. The spacer can be made of metal and / or polymeric material. Metallic materials such as aluminum or stainless steel and polymers such as polyethylene, polycarbonate, polypropylene, polystyrene, polybutadiene, polyesters, polyurethanes, polymethyl methacrylate, polyacrylates, polyamides, polyethylene terephthalate, polybutylene terephthalate, acrylonitrile butadiene styrene, acrylonitrile styrene acrylate, styrene-acrylonitrile copolymer are well suited. The spacer, when made of polymeric material, can be reinforced with fibers, for example, glass or carbon fibers.To ensure the airtightness of the volume containing the air gap, sealing beads are arranged between the inner faces of the panes and the side edges of the spacer. The sealing beads are, for example, made of polyisobutylene. A desiccant material can be added to the spacer to absorb any residual moisture that may form. found in the volume containing the air gap. The desiccant material may be any material capable of allowing air dehydration such as molecular sieve, silica gel, CaCl2, Na2SO4, activated carbon, zeolites and / or a mixture thereof.

[0032] The insulating glazing 4 is arranged between the wall 2 and a glazing bead 5. The wall 2 has a first face 2a intended to be oriented towards the interior of the building in which the structure is intended to be installed and a second face 2b intended to be oriented towards the exterior of the building. The insulating glazing 4 has a first face 4a, intended to be oriented towards the interior of the building, and a second face 4b intended to be oriented towards the exterior of the building. The second face 4b of the insulating glazing 4 bears against the first face 2a of the wall 2.

[0033] The glazing bead 5 has a first face 5a intended to be oriented towards the inside and a second face 5b intended to be oriented towards the outside of the building. The first face 4a of the insulating glazing 4 is in contact with the second face 5b of the glazing bead 5. The structure 1 further comprises cleats 6 arranged around the periphery of the insulating glazing 4, between the first face 2a of the wall 2 and the second face 5b of the glazing bead 5. The cleats 6 are crossed by fixing elements 7 such as fixing screws or nails, for example by four fixing elements as illustrated in [Fig.2]. In an alternative, the structure 1 comprises six fixing elements in order to increase the pressure of the glazing bead 5 on the insulating glazing 4 and thus obtain a better hold.

[0034] The wall 2 comprises a groove 8 arranged on the first face 2a taking the form of a rectangular circumference. The groove 8 contains an adhesive joint 9 in contact with the second face 4b of the insulating glazing 4. In this way the insulating glazing 4 is fixed to the wall 2 by means of the adhesive joint 9 and the pressing force generated by the glazing bead 5 and the fixing elements 7. The adhesive joint 9 also ensures a seal between the exterior and the insulating glazing 4.

[0035] In an alternative, the wall 2 does not have a groove 8. The adhesive joint 9 is directly affixed to the first face 2a.

[0036] The material of the adhesive joint 9 is a silane-modified polymer because it has properties of permeability, polymerization time and mechanical performance suitable for the assembly of the structure 1.

[0037] The structure 1 optionally comprises a sealing gasket 10 making it possible, in particular, to prevent the infiltration of water or dust. The gasket 10 is arranged in contact with the second face 4b of the insulating glazing 4 and the opening 3.

[0038] Referring now to [Fig. 3], there is illustrated a sectional view of a structure 101 according to a second embodiment of the invention. The structure 101 comprises an opening 103 of rectangular shape and a wall 102 having a first face 102a and a second face 102b. In an alternative, the opening 103 has a shape square. With reference to [Fig. 4], the opening 103 has a first side 103a on which a first batten 111a is arranged, the first side 103a being intended to be oriented vertically when the structure 100 is installed in the building, a second side 103b intended to be oriented horizontally, in the upper part of the wall 2 on which a second batten 111b is arranged and a third side 103c intended to be oriented vertically on which a third batten 111e is arranged. With reference again to [Fig. 2], the structure 100 comprises an insulating glazing unit 104, having technical characteristics similar to those of the insulating glazing unit 4 presented in the first embodiment, in contact with the first batten 111a, the second batten 111b and the third batten 111e. The insulating glazing 104 has a first face 104a intended to be oriented towards the interior of the building, and a second face 104b intended to be oriented towards the exterior.An adhesive joint 109 is arranged between the cleats 111a, 111b, 111c and the second face 104b of the insulating glazing 104.

[0039] In one alternative, the cleats are directly integrated into the wall 102. In another alternative, the wall 102 has offsets in place of the cleats.

[0040] In an alternative of the second embodiment, a fourth cleat 11 Id (not shown) is arranged in the lower part of the opening 103. The glue joint 109 is also arranged on the fourth cleat 11 Id.

[0041] According to the invention, the structure 101 comprises damping means 200. These damping means 200 are arranged between the insulating glazing and the structure. These damping means are used to attenuate or even eliminate the vibrations transmitted to the glazing.

[0042] In a first embodiment visible in [Fig. 5], the damping means 200 comprise at least one elastic strip 202. This elastic strip 202 is made of an elastically deformable material. This elastically deformable material is a plastic, polymer or rubber. For example, the deformable material is an expanded or crosslinked polyethylene. This strip of elastic material is arranged between the face of the glazing 4 in contact with the cleats and the cleats 111a, 111b, 111c, 111d.

[0043] The elastic strip 202 is installed in several ways. A first way consists of gluing the elastic strip to the cleats and gluing the glazing 4 to said elastic strip.

[0044] A second way consists of screwing the elastic band 202 onto the cleats 11a, 111b, 111c, 111d. For this, the elastic band 202 is placed on the cleat(s) and a screw is inserted. In a variant, the elastic band 202 is hollowed out, this hollowing is arranged so that the screw is inserted therein.

[0045] This first embodiment is compatible with the first embodiment or the second embodiment.

[0046] In the first embodiment, the elastic strip 202 is arranged at the interface between the glazing 4 and the wall 2 visible in [Fig.7]. It is then understood that the elastic strip is arranged between the surface of the glazing 4 facing the wall and said wall.

[0047] The elastic strip 202 may, furthermore, be arranged between the glazing and the cleat 6. In this case, the elastic strip 202 is arranged on the edge of the glazing as visible in [Fig.8]. In this case, the elastic strip may have an L-shaped section as visible in [Fig.6]. Furthermore, this elastic strip 202 may be arranged between the glazing, the cleat 6 and the glazing bead and have a U-shape, as visible in [Fig.6], and therefore be in contact with the edge of the glazing and the facing surface of the wall 2 and the facing surface of the glazing bead 5 as visible in [Fig.9].

[0048] In the case of the second embodiment, the elastic strip 202 is arranged at the interface between the glazing 4 and the wall 2 as visible in [Fig. 10]. It is then understood that the elastic strip is arranged between the edge of the glazing and said wall. The elastic strip 202 can, furthermore, be arranged between the glazing and the cleats 6 as visible in [Fig. 11]. In this case, the elastic strip can have an L-shaped section. It is then understood that the elastic strip is in contact with the edge of the glazing and the elastic strip between the surface of the glazing and the cleats.

[0049] In this first embodiment, the damping means 200 comprise at least one strip 202 made of elastic material or a plurality of strips. In the case of several strips, these are distributed over the surface of the glazing. In the case of a single strip, this extends mainly or partly around the periphery of the glazing.

[0050] Optionally, the elastic strip 202 is overmolded onto the glazing. This overmolding makes it possible to avoid a step of positioning the elastic strips while ensuring their correct positioning.

[0051] In a second embodiment, the glazing is mounted in the opening by means of damping means 200 in the form of at least one profile 204 as visible in Figures 12 and 13. This profile is made of metal or plastic and has a straight or L-shaped shape and a U-shaped or L-shaped section. This profile 204 is then arranged to at least partially encapsulate the glazing. The profile 204 can extend over at least a portion of at least one side of the glazing. The profile 204 is assembled to the glazing by gluing or by force-fitting or screwing. In the case of screwing, the glazing and the profile are pierced.

[0052] In this second embodiment, the profile 204 comprises at least one damping element 205.

[0053] In a first option, the damping element 205 is a pad made of an elastic material. This pad is fixed to the profile by gluing or by snap-fastening. For snap-fastening, a possible solution is to have a pad which comprises a projecting part which snaps into a housing of the profile.

[0054] The glazing and its profile(s) are then installed in the location provided for this purpose. The pads are arranged on the profile(s) so that the pad forms an interface, directly or indirectly, between the glazing and the wall as seen in Figures 14 and 15. In the case of a profile with an L-shaped or U-shaped section, each branch of the L or L may have one or more pads. Similarly, the damping elements may be arranged on the face of the profile in contact with the glazing or in contact with the wall or the cleats.

[0055] In a second option, the damping elements are springs. In this variant, the springs are preferably helical.

[0056] In this second embodiment, the damping elements are arranged at the interface between the profile and the glazing and / or between the profile and the surface in contact with the profile once mounted, i.e. the wall or the cleats.

[0057] It is possible to combine the execution modes. For example, it is possible to have a metal profile comprising pads on its outer face and on its inner face, that is to say its surface in contact with the glazing, one or more strips of elastic material.

[0058] Of course, the present invention is not limited to the illustrated example but is susceptible to various variations and modifications which will appear to the person skilled in the art.
