Description

[Technical Field]

[0001] The present invention relates generally to the lining of barriers for barrier or aesthetic purposes, and more particularly to a spacer accessory positioned laterally between a lined barrier and a lining partition to space the partition from the lined barrier. [Background technology]

[0002] Barriers such as walls, ceilings or roofs of buildings are often lined during renovation or new construction to obtain or improve the acoustic or thermal insulation of a building or a particular room. For this purpose, a lining partition (false wall or false ceiling) is placed against a lining frame, which itself is fastened to the structural elements of the barrier to be lined at a given distance from the lining frame. A thermal and / or acoustic insulating filler (often called an insulation system) is fitted between the barrier to be lined and the lining partition.

[0003] An insulation system typically comprises, on the one hand, one or more layers of fibrous insulating material, such as mineral wool, and, on the other hand, at least one wind or water vapor barrier membrane, which is usually placed between the layer of fibrous material and a partition layer, typically glued to the partition, and optionally placed between two layers of fibrous material.

[0004] The fastening of the lining frame to the structural elements of the barrier to be lined is carried out at regular intervals using spacer accessories. Each spacer accessory comprises a rod-shaped body extending perpendicular to the barrier to be lined and to the lining partition, one end of the body comprising means for fastening the spacer accessory in a cantilever manner to the structural elements of the barrier to be lined, and the other end of the body comprising means for assembling the spacer accessory to the lining frame. Such spacer accessories are known, for example, from WO 2006 / 061538.

[0005] During installation, the isolation system, and thus the membrane, is typically attached to the rods of the spacer accessory, which causes multiple punctures in the layer of fibrous material and, if applicable, in the membrane. These punctures are particularly detrimental to the membrane, as they alter its permanent or selective airtight function. Punctures in the membrane can also be the initiation of tears that can widen when tension is applied to the membrane.

[0006] To partially avoid this problem, it is known to arrange the membrane inside the lining frame between this rear part and the lining partition, so that the membrane is not traversed by the spacer accessories and can therefore remain intact, at least initially.

[0007] However, this is only a partial solution: fastening the lining partition to the lining frame involves puncturing the membrane with fasteners (staples, screws, nails, etc.), which to a lesser extent compromises the airtightness of the membrane.

[0008] Positioning the membrane in front of the lining frame creates another technical problem: there cannot be any gap space between the membrane and the lining partition. However, it is often necessary to install various cables or hoses behind the lining partition, especially for water, ventilation, electricity, or communication networks. In that case, it is difficult to imagine placing cables and cable accessories between the membrane and the lining partition. In fact, the cables may not be properly fastened unless holes are made in the membrane. The membrane may also be damaged or overstretched by the cables or by the cladding, fastening, or connection accessories.

[0009] These cables may necessarily be placed behind the membrane, but then it is no longer possible to access them for maintenance or to upgrade the wiring without removing the membrane or making an opening in it. Furthermore, wiring operations may be carried out after the lining of the barrier for logistical reasons or because of needs or technological advances, which likewise requires the removal or opening of the membrane by people who are generally not experts in barrier lining and insulation. Summary of the Invention [Problem to be solved by the invention]

[0010] One object of the present invention is to provide a technical solution for installing a membrane without compromising the integrity or tightness of the membrane. [Means for solving the problem]

[0011] To that end, the invention proposes a spacer device for fastening a lining frame to a structure to be lined, the device comprising:

[0012] - a so-called axially extending main part, one end of which comprises a plate fastened to the structure to be lined and the other end of which comprises a membrane retainer,

[0014] The coupling means is characterized in that it comprises sliding means that allow the second jaw to slide into the first jaw to hold the membrane between the two jaws.

[0015] One of the advantages of the present invention and the sliding of the second jaw into the first jaw is that it simplifies the joining of the two jaws. In fact, the sliding according to the present invention does not require deformation of one of the jaws relative to the other to occur. Therefore, it is absolutely possible for the first jaw and / or the second jaw to be made of a material with low or no elastic deformation.

[0020] According to one example, the first jaw includes a top surface, sides, and walls used to support a ridge or groove, and the second jaw includes a base with two protrusions extending therefrom, each of the protrusions having an outer surface and an inner surface, the inner surfaces of the protrusions being parallel and each supporting a groove or ridge.

[0021] According to one example, the first jaw comprises two disposed half jaws and assembly means for enabling the two half jaws to fit together to form the first jaw.

[0022] According to one example, each disposed half jaw is provided with a notch, the half jaws being such that the notches cooperate to form a housing into which the main portion fits.

[0023] The invention further comprises an apparatus for lining a barrier, the apparatus comprising: at least one spacer device according to the invention, at least one insulating material; - a wind or vapor barrier membrane (M) attached to the spacer accessory (10); Equipped with The membrane is characterized in that it is clamped between a first jaw and a second jaw of the spacer device.

[0024] The present invention also relates to a method for retaining a membrane on a spacer device, the method comprising: - providing a spacer device according to the invention fastened to a barrier, the device comprising a so-called axially extending main part, the main part including one end which is the first jaw of the membrane holder; - providing an insulating material; - providing a wind or vapor barrier or water vapor check membrane; - placing the membrane on the top side of the first jaw; - providing a second jaw and positioning it adjacent to the first jaw, the groove and the ridge being aligned; - moving the second jaw to allow the ridge to fit into the groove, the membrane being positioned between the ridge and the groove; Includes:

[0025] The present invention further relates to a method for installing a barrier lining device, the method comprising: - providing at least one spacer device according to the invention; - fastening the spacer device via its fastening plate to the barrier to be lined; - providing an insulating material and putting it into position; - retaining the membrane on the spacer device using the method for retaining a membrane according to the invention; Includes:

[0026] According to one example, the installation method includes a step of decoupling the second jaw from the first jaw after fastening the spacer device to the barrier and before holding the membrane to the spacer device.

[0027] According to one example, the installation method includes the steps of providing two half jaws forming a first jaw and assembling them around the main part after fastening the spacer device to the barrier and before holding the membrane to the spacer device.

[0029] In the example illustrated in FIG. 1, the particular case is to insulate the loft of a building, which is achieved by lining the exterior walls 1 and the roof 2 of this building.

[0030] The roof 2 here conventionally comprises a wooden framework forming panels 3 supporting rafters 4 on which roof elements 5 rest.

[0031] The lining device according to the invention is arranged against the roof frame and on the exterior walls, and comprises a lining frame which, on the one hand, forms horizontal battens 6 for lining the roof and, on the other hand, forms vertical battens 7 for lining the walls 1. These battens are generally called furring strips in the case of the walls and rafters and / or beams in the case of the roof.

[0032] The lining battens 6 and 7 are fastened to structural elements of the roof 2 and of the wall 1 which is lined by a number of spacer accessories 10, respectively.

[0033] Each spacer accessory 10, visible in Figures 2a and 2b, comprises a central part 11 in the form of a rod 12 extending along an axis X1 and provided with its own fastening means 14 to a barrier, which in a first embodiment may be a roof 2 or a wall 1; the other end of the spacer accessory, called the front, comprises a fitting provided with means 30 for assembling itself with battens 6, 7 that ensure the accessory's retention. When installed, the rod 12 is arranged to extend in a direction substantially perpendicular to the wall 1. In the case of a roof, the rod 12 is arranged to extend in a direction substantially perpendicular to the ground in order to level the false ceiling relative to the ground. Panels of insulating material are arranged between the roof 2 or wall 1 and the battens 6, 7 used to support the lining barrier.

[0034] The spacer accessories 10 used for lining the roof are fastened to the rafters 4. For this purpose, the spacer accessories each comprise, as fastening means 14, a fastening plate or vertical base 141 which is screwed to the side of the corresponding rafter 4. The spacer accessories 10 fastened to the wall 1 each comprise, for this purpose, as fastening means 14, a horizontal fastening plate 142 which is screwed to the wall 1.

[0035] The plates 141, 142 may be part of the same piece as the rod 12 or may be pieces that are attached to the rod 12 by various means.

[0036] According to one advantageous feature visible in FIG. 3 , the rod 12 is designed to allow its length to be adjusted. The rod 12 comprises a first portion 121 and a second portion 123. The fastening means 14 of the rod are arranged on the first portion 121, while the assembly means 19 with the battens 6, 7 that ensure the attachment of the accessories are arranged on the second portion 123, and vice versa. Adjustment means 125 are provided to adjust the position of the second portion relative to the first portion, thereby allowing the length of the rod to be adjusted. Such adjustment means 125, for example, allow the first and second portions to slide relative to each other. This sliding movement can be achieved, for example, by a system of rails or a system using a tube along which a sliding rod slides. However, other systems can be used, such as a system in which the two portions are fastened by a notch.

[0037] Thereby, each spacer accessory has an overall length (corresponding to the distance between its end points along its longitudinal direction) which, when it comprises all the fastening plates, is typically comprised between 100 and 200 to 350 millimeters.

[0038] At one end, opposite the fastening means 14, the rod 12 comprises means 13 for mounting the membrane. These mounting means 13 comprise a first jaw 15 and a second jaw 17. The first jaw 15 is attached to the central part 11 by attachment means or is part of the same piece as the central part 11.

[0039] The first jaw 15 cooperates with the second jaw 17 by means of coupling means 16, as can be seen in Figure 4. These coupling means 16 are supported by the first jaw 15 and the second jaw 17.

[0040] According to the invention, the coupling means 16 comprise sliding or slider means 160. These sliding means 160 are based on a coupling formed by a groove 162 and a ridge 164, as can be seen in FIG.

[0041] According to a first embodiment that can be seen in FIG. 5, the first jaw 15 is provided with a pair of grooves 162 and the second jaw 17 is provided with a pair of ridges 164 .

[0042] The second jaw 17 is in the form of an arbitrarily shaped portion known as a base 170 from which extend two protrusions 172. The protrusions 172 each include an outer surface and an inner surface 172a. The protrusions 172 are arranged so that the inner surfaces 172a are parallel to one another. The inner surfaces 172a each support a ridge 164. The ridges 164 are sized to fit within the grooves 162 of the first jaw 15.

[0043] The first jaw 15 is in the form of a portion 150 of any shape having a side barrier 150a that is substantially parallel to the axis of the central portion. The portion forming the first jaw 15 has an upper surface 150b and a lower surface 150c. The side barrier 150a of the first jaw 15 is used to support at least one groove 162.

[0044] The side barrier 150a may have a single peripheral groove 162, as can be seen in FIG. 6, or may have two parallel extending grooves 162, which or these grooves 162 are arranged to allow a ridge 164 of the second machine 17 to fit therein.

[0045] The presence of the single peripheral groove 162 makes it possible to avoid the need for a special inclined position of the second jaw relative to the first jaw 15. This is particularly true in the case of a first jaw 15 whose portion 150 is circular.

[0046] In fact, the operation of this first embodiment consists in positioning the second jaw 17 laterally of the first jaw 15 by aligning the ridge 164 of the second jaw 17 with the groove(s) 162, whereby it is understood that the ridge 164 faces the groove(s) 162. The second jaw 17 can then move laterally to allow the ridge 164 to enter the groove(s) 162. The second jaw 17 then slides relative to the first jaw 15.

[0047] According to one variant of this first embodiment, which can be seen in Figures 7a, 7b, and 7c, the first jaw 15 is arranged so as to present a discontinuity. The first jaw 15 therefore appears on at least two opposite sides in the form of discontinuous blocks, in order to have a stepped profile. The side barriers therefore consist of two parts, a top part 150a' and a bottom part 150a", resulting in a two-part side barrier. The first jaw 15 comprises at least one groove 162 extending in the plane of the first jaw, perpendicular to the axis 11 of the central part. This groove 162 is arranged in the bottom part or in the side barrier on the top part. This groove 162 can also be arranged between the top and bottom parts.

[0048] In a second embodiment, which can be seen in Figures 8a, 8b, and 8c, the first jaw 15 comprises an arbitrarily shaped portion 150 having a pair of ridges 164, and the second jaw comprises a pair of grooves 162.

[0049] The second jaw 17 is in the form of an arbitrarily shaped portion 170, referred to as a base, from which extend two protrusions 172. Each of the protrusions 172 includes an outer surface and an inner surface. The protrusions 172 are arranged so that the inner surfaces are parallel to one another. The inner surfaces each support a groove 162. The grooves 162 are sized to fit over the ridges 164 of the first jaw 15.

[0050] The first jaw 15 is in the form of an arbitrarily shaped section 150 having a side barrier 150a that is substantially parallel to the axis of the central section. The section forming the first jaw has an upper surface 150b and a lower surface 150c. The side barrier 150a of the first jaw 15 is used to support at least one ridge 164.

[0051] The side barrier may have a single ridge 164 as can be seen in FIG. 9 and a periphery, or may include two parallel extending ridges 164, which or these ridges 164 are arranged to allow the groove 162 of the second jaw 17 to fit therein.

[0052] The presence of the single peripheral ridge 164 makes it possible to avoid the need for a special inclined position of the second jaw 17 relative to the first jaw 15. This is particularly true in the case of the first jaw 15 whose portion 150 is circular.

[0053] In fact, the operation of this second embodiment consists in positioning the second jaw 17 laterally of the first jaw 15 by aligning the groove 162 of the second jaw 17 with the ridge(s) 164 of the first jaw 15. It is thereby understood that the groove 162 faces the ridge(s) 164. The second jaw 17 can then move laterally to allow the groove 162 to enter the ridge(s) 164. The second jaw 17 can then slide relative to the first jaw 15.

[0054] According to one variant of this second embodiment, the first jaw 15 is arranged to present a discontinuity. The first jaw 15 therefore appears on at least two opposite sides in the form of a discontinuous block 150, in order to have a stepped profile. The side barrier 150a therefore consists of two parts, a top part 150a' and a bottom part 150a", with the side barrier 150a consisting of two parts. As can be seen in Figures 10a and 10b, the protrusion(s) 164 of the first jaw are arranged on the side barrier at the bottom part or at the top part.

[0055] 11a and 11b, the protrusion 172 of the second jaw 17 is designed to have an L-shape, with a main portion 172a extending substantially perpendicular to the surface of the second jaw 17 and a sub-portion 172b perpendicular to the main portion 172. The sub-portion 172b extends from the inner surface of the main portion 172a, the surface opposite the first jaw 15.

[0056] Advantageously, according to this variant, the gap E between the surface of the second jaw 17 and the sub-portion forms a housing or "groove" into which the first jaw 15 can fit. In this variant, the first jaw as a whole forms a "ridge". Optionally, the first jaw 15 can exhibit local discontinuities in its lower surface which form a housing into which the sub-portion fits.

[0057] In one variant of the two embodiments visible in Figures 12 and 13, the first jaw 15 comprises two half jaws 15'. This variant applies when the first jaw is not part of the same piece as the central portion. The half jaws 15' are preferentially, but not necessarily, identical.

[0058] The jaw halves 15' are fastened together by assembly means, which can take different forms in order to make it possible to assemble the jaw halves 15'.

[0059] According to a first example, the two half jaws 15' are assembled onto each other by screwing. The half jaws are arranged so that the screws make it possible to assemble the two half jaws.

[0060] According to a second example, the two half jaws 15' are assembled onto each other by clipping. To do so, one of the half jaws 15' comprises at least one deformable lamella with a tab, while the other jaw comprises at least one housing. The deformable lamella can be deformed to enter or exit the housing, and in the latter case comprises a notch that fits into the tab.

[0061] According to a third example, each half jaw 15' comprises a lamina and a housing, the housing being arranged facing the lamina of the other jaw.

[0062] In one variation of the example, the two jaw halves 15' are rigidly connected by a hinge, which may be a strip of deformable material or a strap hinge system, that allows the jaw halves to rotate about an axis parallel to the central axis of the central portion or along an axis perpendicular to the central axis of the central portion.

[0063] Each half jaw 15' further comprises notches such that when the two half jaws 15' are joined, these notches form a recess into which the central portion can fit.

[0064] In another variant, the second jaw 17 is arranged to allow the fastening of a frame. To do so, means 30 for fastening the frame are provided. These means consist, for example, of a peripheral groove 31 or two parallel grooves arranged in the second jaw, which allow the fastening of a U-shaped profile. This is because such a profile consists of a metal or plastic sheet folded to have two parallel arms that allow the profile to achieve a U- or C-shape depending on its orientation. The ends of each arm of the profile exhibit an excess thickness that can fit into the grooves and allow the profile to be fastened.

[0065] Alternatively, the fastening means 30 of the frame comprises two parallel arms 33 which extend from the second jaw 17 in a direction parallel to the axis of the central part and are spaced apart so that they can fit into the space present between the two arms of a U-shaped or C-shaped profile.

[0066] Thereby, the installation means 13 comprising a first jaw 15 and a second jaw 17 is used to fasten or attach the membrane M to the spacer device, which is installed after the process for installing the spacer device on the barrier to be lined.

[0067] The installation method includes fastening the central portion to the barrier P to be lined via visible fastening means 14, which can be seen in Figure 14a. This fastening uses screws or nails or adhesive to fasten the central portion 11 at right angles to the barrier P to be lined.

[0068] Next, as can be seen in Figure 14b, if the central portion 11 is adjustable, a step of adjusting the length of the central portion is carried out, which consists in manipulating the adjustment means 125 to make it possible to adjust the length of the central portion, which comprises a first part and a second part that slide relative to each other.

[0069] After this adjustment step, a step is performed consisting of installing a blocking material with the aid of a spacer accessory, which is positioned between the barrier and the first jaw, depending on the configuration of the spacer device.

[0070] The first way to install the isolator is to insert it onto the rod 12. This method of installing the isolator is possible if the first jaw is an attached part of the rod 12. This attachment is performed before the installation of the first jaw 15.

[0071] A second method of installing the insulating material is to position the insulating material so that it rests on the lower surface 150c.

[0072] This lower surface 150c is, in a first option, provided with teeth that extend perpendicular to the lower surface 150c and that allow the teeth to penetrate the blocking material and hold it in place.

[0073] According to a second option, the spacer device 10 comprises an additional plate fastened onto the rod 12. This plate provides a surface on which the insulating material rests.

[0074] This second method is possible for the first jaw 15 to be part of the same piece as the rod 12 or to be attached to the rod.

[0075] In the case of a first jaw 15 that is not part of the same piece as the rod, an optional step (as can be seen in FIG. 14c) consists of carrying out fastening the first jaw to the main part. Indeed, in this case, the kit of spacer devices comprises a central part, a first jaw and a second jaw, and the first jaw 15 is not necessarily placed together with the central part. It is therefore necessary to have a step of fastening the first jaw 15 to the main part.

[0076] Another optional step (not shown) for the two methods of installing the insulation consists of disassembling the second jaw from the first jaw 15. In practice, the kit of spacer devices comprises a central part, a first jaw 15 and a second jaw 17, the second jaw 17 potentially being pre-attached to the first jaw 15.

[0077] As can be seen in Figure 14c, the membrane attachment / fastening method then consists of providing a membrane M. Advantageously, the membrane M is an airtight membrane and / or a water vapor management membrane, preferably a membrane capable of fulfilling both purposes simultaneously. Advantageously, the water vapor management membrane is a vapor control membrane or hygroregulating membrane, meaning that its permeability to water vapor varies based on the ambient relative humidity. The membrane M consists of one sheet or several sheets assembled together.

[0078] In a second step, which can be seen in Fig. 14d, this membrane M is placed on the first jaw 15. The membrane M is placed so as to cover the upper surface of the first jaw 15, in particular the groove(s) arranged in this first jaw.

[0079] The third step then consists in providing the second jaw 17 and placing it next to the first jaw, as can be seen in Figure 14e, with the groove 162 facing the ridge.

[0080] The fourth step then consists in assembling the second jaw 17 with the first jaw 15. To do so, the second jaw 17 is moved so that the protrusion 164 fits into the groove 162. This insertion is carried out so that the membrane M is placed between the first and second jaws. As can be seen in FIG. 14f, it can be seen that the membrane M is placed between the groove and the protrusion. In fact, the groove 162 and the protrusion 164 are sized to allow a space to exist when the protrusion is inserted into the groove. This space is what allows the membrane to take its position between the groove and the protrusion.

[0081] The second jaw 17 is then slid onto the first jaw 15 for assembly. Ideally, the second jaw 17 has dimensions such that the length of the groove 162 and the length of the ridge 164 are substantially the same.

[0082] The advantage of this spacer device 10 is that it allows the placement of the membrane without violating its integrity, since the membrane M placed between the first jaw 15 and the second jaw 17 is held without the need for puncturing the membrane.

[0083] This membrane attachment / fastening process is repeated for each spacer device that the barrier lining apparatus comprises. Note that such an apparatus comprises at least one spacer device, a wind control or vapor barrier membrane M attached to a spacer accessory according to the present invention.

[0084] In another variant, which can be seen in Figures 15 and 16, the two half jaws forming the second jaw 17 are arranged to allow the fastening of a frame. To do so, means 30 for fastening the frame are provided. These fastening means 30 are arranged on the top surface of at least one half jaw 170. These means 30 consist, for example, of a groove 31 that can be peripheral or form two parallel sections arranged in the second jaw that allow the fastening of a U-shaped profile P. In practice, such a profile consists of a plastic or polymer folded to have two parallel arms that allow the profile to achieve a U- or C-shape depending on its orientation. The ends of each arm of the profile exhibit excess thickness that can fit into the groove and allow the profile to be fastened.
