Description

Technical Field

[0001] The present invention generally relates to wall surface linings for blocking or aesthetic purposes. Specifically it relates to bracing accessories (fastening accessories) arranged between the wall surface to be lined (the wall surface to be clad) and the cladding material in order to keep the cladding material away from the wall surface to be lined.

Background Art

[0002] As shown in FIG. 1, lining from the inside of the wall surface, such as the walls, ceilings, roofs of a building, etc., is often carried out during renovation or new construction in order to obtain or improve the acoustic or thermal insulation of the building or a specific room. For this purpose, the cladding material 2 is attached to the lining frame, and the lining frame itself is attached to the structural element 1A of the wall surface 1 to be lined at a given distance from the lining frame. Thermal and / or acoustic insulation packing (often called an insulation coating) is inserted between the wall surface 1 to be lined and the cladding material 2.

[0003] The insulation packing typically includes, on the one hand, one or more layers of an insulation product 3 in the form of a foldable panel or roll, such as a biological-derived insulator like mineral wool (glass, stone), wood fiber, or a porous reflective insulator, and, on the other hand, at least one sealing film 4, i.e., a vapor barrier film and / or an erosion vapor inhibitor. This film 4 most often intervenes between the insulation product 3 and the cladding material 2, typically adjacent to the cladding material and / or optionally inserted between two layers of the insulation product. Alternatively, it can also be firmly connected to the insulation product 3 or separately added between the insulation product and the cladding material 2.

[0004] The lining frame is attached to the structural element 1A of the wall surface to be lined 1 by regularly spaced bracing accessories 5 (fastening accessories 5), which are generally called "hangers" for ceiling and roof linings and "bracings" for wall linings. Each bracing accessory includes a rod-shaped body 5A that extends transversely to the wall surface to be lined 1 and to the covering material 2. The first end of the accessory is provided with an attachment 5B that is cantilevered to the structural element 1A of the wall surface to be lined 1, and the second end is provided with a fastener 5C that attaches to the filler plate 6 of the lining frame.

[0005] During installation, the sealing packing is inserted onto the rod 5A of the bracing accessory 5, causing multiple perforations in the sealing product 3 and the membrane 4. In this case, the permanent or selective sealing function of the membrane 4 is impaired, and these perforations particularly damage the membrane 4. Perforations in the membrane 4 may also constitute a trigger for rupture, which can spread if tension is applied to the membrane 4.

[0006] French Patent Application Publication No. 2925929 describes the implementation of a pair of jaws that, in order to ensure the continuity of the seal, are fixed by being clamped in a groove located at the second end of the rod of a hanger, and then clamp the sealing film near the point of perforation by the rod.

[0007] While such hangers are effective, they have several drawbacks, including the fact that their attachment is irreversible unless the jaw section is destroyed. [Overview of the project] [Problems that the invention aims to solve]

[0008] The present invention aims to provide a technical solution to the aforementioned disadvantages. [Means for solving the problem]

[0009] More specifically, in at least one embodiment, the proposed technology relates to a bracing accessory suitable for attaching at least one shielding product to a lined wall surface, comprising a rod having a first end fitted to be attached to a structural element on the wall surface, and a second end fitted to penetrate the shielding product and the sealing film. The bracing accessory described above is characterized by including a sealing element with a hole, preferably a through hole, the periphery of which has a shape complementary to the cross-section of the rod, and being made of an elastic material suitable for enabling reversible elastic mounting of the rod by friction of the sealing element, and the rod being substantially flat in shape and preferably metallic. [Brief explanation of the drawing]

[Figure 7]Figure 7 is a schematic perspective view of an assembly formed by a lined wall surface, bracing accessories, and a filler plate according to a second embodiment of the present invention. [Modes for carrying out the invention]

[0012] The expression "reversible elastic mounting" refers to the non-deterministic mounting of one component to another by elastic deformation. After mounting the bracing accessory to the surface of the wall to be lined, depending on the density of the shielding product to be implemented, the shielding product (mineral wool, honeycomb reflective shielding material) is either inserted directly into the rod, or the shielding product (rigid wood fiber shielding panel) is attached to the rod, thereby sliding the rod between two consecutive shielding panels. In either case, the second end of the rod penetrates the shielding product within the meaning of the present invention. Similarly, the rod preferably penetrates a sealing element in a hole provided for this purpose. After inserting the sealing film onto the second end of the rod, the operator inserts the sealing element around the rod through the hole provided for this purpose, and then slides the sealing element into the film. Due to the elastic properties of the sealing element, under the influence of elastic return, the sealing element can be elastically deformed to conform to the periphery of the rod while a compressive force is applied to the rod. In this way, the sealing element is elastically attached to the rod by overcoming the frictional resistance, i.e., the tribological properties, to its removal. Nevertheless, such a sealing element remains removable if sufficient tensile force is applied by the operator. Due to the elastic properties of the material present at the interface between the rod and the sealing element, the sealing element conforms perfectly to the surface of the rod, and thus the contact surface and desired sealing properties at this interface are maximized.

[0013] Accordingly, the present invention is based on the concept of providing a bracing element (retaining element) that is easy to use and removable while providing satisfactory airtightness around a rod. The implementation of reversible elastic attachment of the sealing accessory to the rod also makes it possible to adapt the position of the sealing accessory according to the operator's requirements, for example, the thickness of one or more sealing products, and in particular the final position of the sealing film. In other words, it is not necessary to pre-define the area for attaching the sealing element to the rod when manufacturing the bracing accessory.

[0014] Within the scope of the present invention, the rod is said to be "substantially flat" in the sense that it extends mostly within the same theoretical plane, while preferably having slight folds and / or embossed lines at its lateral edges to increase rigidity. A substantially flat rod has the advantage of increasing the contact surface for sealing accessories, thus improving satisfactory sealing and reliability.

[0015] According to a particular embodiment, the sealing element includes a raised portion in which the hole is formed, which preferably extends along the axis of the rod over a distance of more than 2 mm, preferably more than 5 mm, and preferably more than 10 mm.

[0016] Such ridges can increase the contact surface between the sealing element and the rod, thereby strengthening the seal at this interface.

[0017] According to a particular embodiment, the raised portion extends from a flat base, preferably circular, elliptical, square, or rhombic, which is preferably coated with an adhesive and / or a grippy coating, and the flat base is adapted to abut against the sealing film when the sealing element is inserted onto the rod.

[0018] Such a flat base, by contacting the sealing film along a plane perpendicular to the rod axis, can cover any possible tears in the film around the insertion opening, thereby strengthening the sealing force.

[0019] According to certain embodiments, the elastic material that constitutes at least the periphery of the hole, or otherwise the entirety of the sealing element, has a Shore A hardness of 20 to 100, preferably 30 to 80, and preferably belongs to the group comprising elastomers such as rubber, butyl, compounds comprising: styrene, butadiene or ethylene, compounds comprising: polyester, polypropylene or EPDM, polyurethane, or thermoplastic olefin.

[0020] By selecting such an elastic material, it becomes possible to easily achieve high reliability, leak resistance, and reversible attachment in the hole.

[0021] According to certain embodiments, the entirety of the sealing element is constituted by the elastic material. The production of such an integrated sealing element is easier compared to a sealing element formed of a plurality of different materials.

[0022] According to certain embodiments, the sealing element includes at least one so-called rigid material, which has a flexural modulus of more than 100 MPa, preferably more than 1000 MPa, preferably belongs to the group comprising metals and thermoplastic plastics, and constitutes the periphery of the flat base and / or the raised portion.

[0023] By selecting such a relatively hard material, it becomes possible to improve the contact between the flat base and the film and / or facilitate the grasping of the sealing accessory by the operator, as compared to the elastic material disposed on the periphery of the through hole.

[0024] According to certain embodiments, the sealing element includes means for reversibly fixing the sealing element to a rod, preferably a wedge.

[0025] The implementation of additional reversible fixing members allows for enhanced attachment of the sealing element to the rod, in addition to the reversible elastic attachment by friction already provided by the sealing element in its hole. This, for example, allows for better support of the weight of the blocking product.

[0026] According to a particular embodiment, the sealing element is formed from two jaws adapted to grip the rod, in a reversible elastic mounting structure by friction of the sealing element onto the rod.

[0027] This implementation of the jaw portion makes it possible to fasten the sealing element directly to the rod without the need to slide the sealing element from the second end of the rod, especially through its tip.

[0028] According to a particular embodiment, the two jaws are connected in a rotatable (pivotable) manner.

[0029] According to certain embodiments, the two jaws are two separate parts, preferably connected by a hinge. According to certain alternative embodiments, the two jaws form part of the same part, which has fold lines adapted to allow one jaw to pivot relative to the other.

[0030] According to a particular embodiment, the rod includes a tip at its second end, which is preferably foldable between a so-called insert structure in which the tip is positioned within the extending direction of the rod and a structure in which all or part of the tip is inclined outward from the axis of the rod.

[0031] The tip at the end of the rod facilitates the insertion of one or more shielding products and membranes. On the other hand, tilting the tip to the side after insertion prevents the operator from touching the tip after installation and allows for optional clipping of the filler plate.

[0032] According to a particular embodiment, the rod includes at its second end a device for fastening to a filler plate, which preferably includes two grooves positioned on the periphery of the rod in a theoretical plane perpendicular to the axis of the rod.

[0033] This allows the bracing accessory rods to be mounted directly to the filler plate, independently of the sealing element, to ensure a satisfactory mechanical connection.

[0034] According to a particular embodiment, the rod has at least one member protruding from the rod for holding the blocking product, which preferably has teeth or flaps.

[0035] Such a retaining member makes it possible to hold the barrier panel in place, for example, when the barrier panel tends to slide along the rod under its own weight.

[0036] According to a particular embodiment, the rod has a rough surface adapted to contact the periphery of the hole in the sealing element.

[0037] Compared to the rest of the rod, these surface areas with increased roughness allow for a stronger attachment of sealing accessories to the rod by increasing the frictional resistance of the rod as it becomes loose.

[0038] According to a particular embodiment, the bracing accessory has a cup which is adapted to be positioned between the sealing product and the membrane and is adapted to form an opposing support to the sealing element for clamping the membrane around the insertion opening of the membrane.

[0039] According to a particular embodiment, the cup is adapted to be mounted so as to swivel and slide around the rod.

[0040] According to an alternative embodiment, the cup is attached to the rod by a friction-based, reversible elastic mounting and / or reversible fixing member.

[0041] The present invention also relates to an assembly including a lined wall surface having a structural element to which at least one such bracing accessory is attached, wherein the bracing accessory penetrates at least one barrier product and at least one sealing film.

[0042] According to an alternative embodiment, the shielding panel is either pre-equipped with a sealing film or does not have a sealing film, in which case the film is separately inserted into the rod of the bracing accessory.

[0043] According to a particular embodiment, at least one of the bracing accessories is attached to a filler plate, and the filler plate itself is attached to a covering material.

[0044] According to a particular embodiment, the assembly has at least one acoustic damping member at the interface between the bracing accessory and the filler plate.

[0045] According to a particular embodiment, the sound dampening member is positioned between the end of the rod near a bend and the filler plate to limit the propagation of sound waves and possible clicking sounds between the rod and the filler plate.

[0046] The present invention also relates to a method for attaching at least one shielding product to a wall surface to be lined, and includes at least the following steps, in this order:

[0047] - The first end of the rod of such a bracing accessory is attached to the structural element on the wall surface.

[0048] - The step of positioning at least one barrier product against the wall surface such that the rod described above passes through it,

[0049] - A step of inserting the sealing film and the sealing element of the bracing accessory into the second end of the rod.

[0050] The present invention also relates to a method for lining a wall surface, which includes the following methods: attaching at least one such blocking product to the bracing accessory, installing at least one filler plate, and installing a covering material on the filler plate.

[0051] Further features and advantages of the present invention will become apparent from the following description of specific embodiments, which are given merely as illustrative and non-limiting examples, as well as from the accompanying drawings.

[0052] The various elements shown in the figures are not necessarily shown to actual scale, and the focus is on illustrating the general operation of the present invention. In the various figures, unless otherwise indicated, the same reference numeral represents a similar or identical element.

[0053] Some specific embodiments of the present invention are shown below. It should be understood that the present invention is by no means limited by these specific embodiments, and that other embodiments are entirely possible.

[0054] Figures 2 and 3 show, respectively, a rod 5A and a sealing element 7 of a bracing accessory 5 according to a first embodiment of the present invention, where the rod 5A of the accessory 5 is substantially flat in shape and metallic. Figure 4 shows an assembly formed by a wall surface to be lined 1, such a bracing accessory 5, and a filler plate 6.

[0055] In the context of the lining method according to this first embodiment, first, the first end of the rod 5A of the bracing accessory 5 is attached to the structural element 1A of the wall surface 1. More specifically, as shown in Figure 4, this attachment is carried out through a screw-in hole formed in the plate-shaped portion 5B of the rod 5A.

[0056] According to an alternative embodiment, such fastening of the rod to the structural element may be provided by any equivalent fastening system, for example, by a head positioned at the first end of the rod and adapted to be attached to a filler plate, the filler plate itself being fixed to the surface of the wall to be lined.

[0057] Once the bracing accessory 5 is attached to the wall surface 1, at least one bracing product 3 is positioned relative to the wall surface 1, as shown in Figure 4, so that the rod 5A penetrates the bracing product 3 from one side to the other.

[0058] According to the alternative embodiment, the blocking product 3 is inserted directly onto the rod 2A, or the rod 2A is attached to the blocking product 3, thereby sliding the rod 2A between two consecutive blocking panels 3. Figure 4 considers these two alternative embodiments, and the apparent cross-section of the blocking product 3 needs to be considered as a cross-section in the first case, or as the end of the blocking product 3 to which the rod is attached in the second case.

[0059] In particular, during this step of installing the shut-off product 3, attention should be paid to the implementation of teeth 5E on the rod, which enable the shut-off product to be held on the rod. These teeth may be within or directly beneath the thickness of the shut-off product.

[0060] Next, the sealing film 4 is inserted onto the rod 5A. By mounting the tip 5D on the second end of the rod 5A, the perforation of the film 4 and subsequent insertion become easier.

[0061] It should be noted that, according to the alternative embodiment, the membrane 4 is fixed to the blocking product 3 during its manufacture, in which case they are inserted together at the same time, or they are manufactured separately, in which case the installation of the blocking product 3 and the membrane 4 is carried out in two different steps.

[0062] Subsequently, the sealing element 7 of the bracing accessory 5 is inserted onto the rod. More specifically, as shown in Figure 3, such a sealing element has a circular base 7C, with a through hole 7A formed in its center, extending along an axis perpendicular to the flat base by a raised portion 7B more than 10 mm in height. According to this first embodiment, the hole 7A is a substantially flat slot in order to have a shape complementary to the cross-section of the rod. The majority of the flat base 7C and raised portion 7B of the sealing element 7 are made of a so-called hard thermoplastic material with a flexural modulus greater than 100 MPa. Only the slot 7A is coated with soft rubber with a Shore A hardness of 30 to 80.

[0063] To insert the sealing element 7, the operator inserts the sealing element 7 around the rod 5A through a slot 7A provided for this purpose, and then slides the sealing element 7, particularly its flat base 7C, onto the film 4. According to this first embodiment, the outer surface of the base 7C of the sealing element 7, i.e., the surface intended to face the film 4, is coated with adhesive to enhance its sealing force. Due to the elastic properties of the rubber constituting the inside of the slot 7A, it can be elastically deformed to conform to the periphery of the rod 5A while applying a compressive force to the rod 5A under the effect of elastic return. The sealing element 7 is also elastically attached to the rod 5A by counteracting the frictional resistance to its removal, i.e., the properties of tribology. Nevertheless, such a sealing element 7 remains removable if sufficient pulling force is applied by the operator. Furthermore, the elastic properties of the rubber used at the interface between the rod 5A and the sealing element 7 allow the sealing element 7 to perfectly conform to the surface of the rod 5A, thus maximizing the contact surface and desired sealing properties at this interface.

[0064] Before installing the filler plate 6, as shown in Figure 4, the end of the tip 5D is tilted outward from the axis of the rod (5A) along the fold line indicated by the dashed line in Figure 1. Subsequently, the filler plate 6 is inserted into two dedicated grooves 5C located at the rear of the tip 5D. According to a particular embodiment (not shown), an acoustic damping member is placed in these grooves or between the end of the rod 5A near the fold and the filler plate to limit the propagation of sound waves and possible clicking sounds between the rod 5A and the filler plate 6.

[0065] Finally, this lining method can be completed by attaching the covering material 2 (not shown in Figure 4, but shown in Figure 1) to the filler plate 6, for example, by screwing it in. Thus, the covering material 2 is kept at a distance from the wall surface 1 by the bracing accessory 5.

[0066] Figures 5 and 6 show the rod 5A and sealing element 7 of the bracing accessory 5 according to a second embodiment, respectively. This embodiment differs from the first embodiment in that the rod 5A has a solid tubular shape and is made of a thermoplastic material. According to this second embodiment, the rod 5A has a plate 5B at a first end that is adapted to be screwed to a structural element 1A of the wall surface 1. According to alternative embodiments not shown, such fasteners 5B may be provided by any equivalent system, for example, by a perforated plate positioned along the rod, along the axis of the rod. By mounting the flap 5E on the rod 5A, it becomes possible to hold the blocking product 3 on the rod, particularly during the step of installing the blocking product 3.

[0067] According to this second embodiment, as shown in Figure 7, the blocking product 3 and the sealing film 4 are provided separately and separated from each other in the final assembly by a cup 8 that is slidably pivoted and mounted on the rod 5A. According to this second embodiment, the cup 8 has a geometric shape similar to that of the sealing element 7, and together with the sealing element 7, the cup 8 forms an opposing support for clamping the film 4 around the coupling opening. However, according to an alternative embodiment, the cup may have any geometric shape adapted to perform this opposing support function and may have any type of mechanical connection to the rod, such as irreversible mounting, reversible elastic mounting by friction, or reversible mounting by screw or bayonet. In the latter case, the cup 8 may provide a complementary function of holding the blocking product 3 in place to reduce the stress applied to the sealing element 7 by the blocking product 3.

[0068] As shown in Figures 6 and 7, the sealing element 7 includes a cylindrical through-hole 7A in addition to a conical flat base 7C, and extends from this flat base 7C along an axial direction perpendicular to it by a tubular shape 7B exceeding 10 mm in height. Similar to the first embodiment, the periphery of the hole 7A is coated with soft rubber. In a manner similar to the first embodiment, due to the shape complementarity and elastic properties of the rubber constituting the inside of the hole 7A, under the effect of elastic return, the rubber constituting the inside of the hole 7A can elastically deform to conform to the periphery of the rod 5A while applying a compressive force to the rod 5A. Thus, satisfactory sealing at this interface and reversible attachment by friction are ensured. In a supplementary and non-essential manner, a blind hole 9A is created around the rod 5A, and in cooperation with the through-hole created above 9B of the sealing element 7, a wedge 9 can be inserted. This can strengthen the attachment of the sealing element 7 to the rod 9A, and as a result, it can better support the weight of, for example, the sealing product. In a supplementary or alternative manner, the rod 5A may have a surface with increased roughness on a portion of its periphery to enhance the attachment of the sealing accessory to the rod by increasing the frictional resistance of the loosening rod.

[0069] After joining the sealing elements, the lining method can be completed, similar to the first embodiment, by attaching the filler plate 6 and then the covering material 2. Thus, the covering material 2 is kept at a distance from the wall surface 1 by the bracing accessory 5.
