DETAILED DESCRIPTION

[0057] The various elements illustrated in the figures are not necessarily shown to actual scale, the emphasis being more on representing the general operation of the invention. In the various figures, unless otherwise indicated, reference numbers that are identical represent similar or identical elements.

[0058] Several particular embodiments of the invention are presented below. It is understood that the present invention is in no way limited by these particular embodiments, and that other embodiments are perfectly possible.

[0059] FIGS. 2 and 3 respectively show a rod 5A and a sealing element 7 of a bracing accessory 5 according to a first embodiment of the invention wherein the rod 5A of the accessory 5 is of substantially flat shape, and is of metallic nature. FIG. 4 depicts an assembly formed by a wall surface to be lined 1, such a bracing accessory 5 and a filler plate 6.

[0060] In the context of a lining method according to this first embodiment, a first end of the rod 5A of the bracing accessory 5 is first attached to a structural element 1A of the wall surface 1. More specifically, and as illustrated by FIG. 4, this attachment is implemented via perforations formed in a portion in the form of a plate 5B of the rod 5A, in which screws are engaged.

[0061] According to alternative embodiments, such a fastening of the rod to the structural element can be provided by any equivalent fastening system, for example by means of a head arranged at the first end of the rod, and adapted to be attached in a filler plate itself secured to the wall surface to be lined.

[0062] Once the bracing accessory 5 is attached to the wall surface 1, and as illustrated by FIG. 4, at least one insulating product 3 is placed against the wall surface 1, so that the rod 5A passes through the latter right from one side to the other.

[0063] According to alternative embodiments, the insulating product 3 is either plugged directly onto the rod 2A, or attached to the latter, so that the rod 2A is slid between two consecutive insulating panels 3. FIG. 4 allows for these two alternative embodiments, the apparent section of the insulating product 3 needing to be considered a cross-section in the first case, or as the edge of the insulating product 3 in the second case, to which the rod would be affixed.

[0064] Note the implementation on the rod of a tooth 5E which makes it possible to hold the insulating product on the rod, in particular during this step of mounting the insulating product 3. This tooth may be in the thickness of the insulating product or just below.

[0065] A sealing membrane 4 is subsequently plugged onto the rod 5A. The implementation of a tip 5D at the second end of the rod 5A facilitates the perforation and the subsequent plugging of the membrane 4.

[0066] It should be noted that according to alternative embodiments, the membrane 4 is either secured to the insulating product 3 during its manufacture, in which case they are plugged together at the same time, or produced separately, in which case the installation of the insulating product 3 and the membrane 4 is carried out in two distinct steps.

[0067] A sealing element 7 of the bracing accessory 5 is subsequently plugged onto the rod. More specifically, and as illustrated by FIG. 3, such a sealing element comprises a circular base 7C, at the center of which a through-hole 7A is formed extended by a rise 7B with a height greater than 10 mm, along an axis orthogonal to this flat base 7C. According to this first embodiment, the hole 7A is a slot, in order to have a shape complementary to the section of the rod, of substantially flat shape. The flat base 7C and the major part of the rise 7B of the sealing element 7 consist of a so-called rigid thermoplastic material, the flexural modulus of which is greater than 100 MPa. Only the slot 7A is coated with a soft rubber, the Shore A hardness of which is between 30 and 80.

[0068] To plug the sealing element 7, an operator inserts the sealing element 7 around the rod 5A via the slot 7A provided for this purpose, then slides the sealing element 7 and in particular its flat base 7C against the membrane 4. According to this first embodiment, the outer face of the base 7C of the sealing element 7, i.e. the face intended to be oriented toward the membrane 4, is coated with an adhesive in order to reinforce its sealing power. The elastic properties of the rubber constituting the inside of the slot 7A allow it to deform elastically to match the periphery of the rod 5A while exerting on the latter a compression force, under the effect of the elastic return. The sealing element 7 is also resiliently attached to the rod 5A by opposing a frictional resistance, i.e., of a tribological nature, to its removal. Such a sealing element 7 nevertheless remains removable if a sufficient traction force is exerted by an operator. The elastic nature of the rubber used at the interface between the rod 5A and the sealing element 7 also allows the latter to perfectly follow the surface of the rod 7A, and thus to maximize the contact surface and the desired sealing properties at this interface.

[0069] Prior to mounting a filler plate 6, and as shown in FIG. 4, the end of the tip 5D is tilted outside the axis of the rod (5A), along a fold line illustrated by dashed lines in FIG. 1. A filler plate 6 is subsequently inserted into two dedicated grooves 5C arranged at the rear of the tip 5D. According to a particular embodiment (not depicted), an acoustic damping member is arranged in those grooves, or between the end of the rod 5A close to its fold and the filler plate, in order to limit the propagation of sound waves and possible clicking noise between the rod 5A and the filler plate 6.

[0070] Finally, the lining method can be completed by attaching a cladding 2 (not shown in FIG. 4, but visible in FIG. 1) onto the filler plate 6, for example by screwing. The cladding 2 is thus kept at a distance from the wall surface 1 by means of the bracing accessory 5.

[0071] FIGS. 5 and 6 respectively show a rod 5A and a sealing element 7 of a bracing accessory 5 according to a second embodiment, which differs mainly 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 at a first end a plate 5B adapted to be screwed to a structural element 1A of the wall surface 1. According to alternative embodiments, not illustrated, such a fastening 5B can be provided by any equivalent system, for example a perforated plate arranged along the rod, along the axis of the rod.

[0072] The implementation on the rod 5A of a flap 5E makes it possible to hold the insulating product 3 on the rod, in particular during the step of mounting the insulating product 3.

[0073] According to this second embodiment, and as illustrated in FIG. 7, the insulating product 3 and the sealing membrane 4 are provided separately, and separated from one another in the final assembly by a cup 8 mounted slidably pivoting on the rod 5A. According to this second embodiment, the cup 8 has a geometry similar to that of the sealing element 7, with which it forms a counter-support in order to clamp the membrane 4 around its coupling opening. According to alternative embodiments, the cup may however have any geometric shape adapted to fulfill this counter-support function, and have any type of mechanical connection with the rod, for example an irreversible attachment, a reversible elastic attachment by friction, or a reversible attachment by screwing, or bayonet type. In the latter case, the cup 8 can provide a complementary function of retaining the insulating product 3, in order to reduce the stresses exerted by the latter on the sealing element 7.

[0074] As shown by FIGS. 6 and 7, a sealing element 7 comprises, in addition to a flat base of conical shape 7C, a through-hole 7A of cylindrical shape, extended by a tubular shape 7B of a height greater than 10 mm, along an axis orthogonal to this flat base 7C. As in the first embodiment, the perimeter of the hole 7A is coated with a soft rubber. In a manner analogous to the first embodiment, the shape complementarity and the elastic properties of the rubber constituting the inside of the hole 7 A allow it to deform elastically to fit the periphery of the rod 5A while exerting on the latter a compression force, under the effect of elastic return. A satisfactory seal at this interface, as well as reversible attachment by friction, are thus ensured. In a complementary and non-essential manner, a blind hole 9A is produced on the periphery of the rod 9A, for, in collaboration with a through-hole produced in the upward 9B of the sealing element 7, allowing a key 9 to be inserted through. This makes it possible to reinforce the attachment of the sealing element 7 to the rod 9A, such that it can for example better support the weight of the insulating product. In a complementary or alternative manner, the rod 5A can have, on a portion of its perimeter, a surface with increased roughness, in order to reinforce the attachment of the sealing accessory to the rod, by increasing the frictional resistance to the rod coming loose.

[0075] After coupling the sealing element, and similarly to the first embodiment, the lining method can be completed by attaching a filler plate 6 and then a cladding 2. The cladding 2 is thus kept at a distance from the wall surface 1 by means of the bracing accessory 5.
