Description

i

  The present invention relates to a wall insulation device comprising a lining panel and a method of laying said lining panels.

  The doubling panels are widely used in renovation to improve the thermal and acoustic insulation. They intervene in the doubling of walls, the realization of insulating floors or the insulation under crawling roof ...

  They are then generally screwed to a metal frame of galvanized steel sections. But the lining panels can also be screwed onto wooden battens or directly glued to the support wall.

  These traditional fastening systems generate a lot of dust and do not allow disassembly without prejudice

of the isolation device.

  Metal-frame fastening systems strongly deteriorate the walls to which they are attached (parquet,

  ceiling). They do not allow disassembly without prejudice to the decoration of the room.

  In addition, the fastenings on wooden battens of the screw-in doubling panels rigidly join the panel relative to the support wall. Sound transmissions

  solid way then degrade the sound insulation of the room.

  The panels bonded directly to the support wall are, moreover, fixed without the possibility of correcting the flatness of said panels, which may cause the appearance of defects in the surface of the wall made of doubling panels, or requires the fitter exceptional dexterity.

  The object of the present invention is to provide a wall insulation device comprising a lining panel and a method of laying lining panels, simple in their design and operating mode, clean, removable, nondestructive for the frame and acoustically efficient.

  For this purpose, the invention relates to a device for isolating a wall comprising a doubling panel comprising a

  insulating panel, and fastening means for securing said panel, said fastening means having a cylindrical rod and a head.

  According to the invention, the head bears on the insulating panel to fix said doubling panel. In various embodiments, the present invention also relates to the following features which will have to be considered in isolation or in all their technically possible combinations: the lining panel comprises at least three recesses intended to receive the attachment means, the recesses are at a distance from the edges of the doubling panel greater than their own diameter, - a spring centered on the cylindrical rod of each fastening means is placed between said insulating panel and said wall, the head of each fastening means is isolated from the doubling panel by a flat part not coming into contact laterally with said lining panel, - said part is a washer centered on the cylindrical rod of the fastening means, - the wall comprises at least three recesses in which one places a ankle for receiving the fastening means, - the recesses made in the lining panel p for its fixation are closed with a flexible putty, ready to paint,

  - said putty is an acrylic sealant.

  The invention also relates to a method of mounting an insulation device covering an entire wall of length L and width H using at least one wall insulation device comprising a doubling panel, as defined upper. The isolation device as a whole is placed on a useful wall of length L 'and width H' satisfying L '= L - 2j and H' = H - 2j, where j is the width of an expansion joint, each individual individual doubling panel being of width h and length I and comprising at least five

  recesses of diameter d, one central and each of the other four being centered on one side of said panel.

  In order to always use pieces of lining panel having at least three fasteners (which allows adjustment of the flatness), according to the invention, the dimensions of the first lining panel are defined in the direction of its length, then in the width direction, editing is then started - If there is an integer X such that (X + 1/2) I + 1/2 d <L '<(X + 1) I we start editing with a whole dubbing panel in

the sense of length.

  If such an integer X does not exist, the panel is cut out

  the direction of the length so as to obtain a panel length 1 '= (l + d) / 2.

  - If there exists an integer Y such that (Y + 1/2) h + 1/2 d <H '<(Y + 1) h.

  we start the assembly with an entire doubling panel at the width.

  If such an integer Y does not exist, the doubling panel is cut in the width direction so as to obtain a

  doubling panel width h '= (h + d) / 2.

  In various embodiments, the present invention also relates to the following features which will have to be considered in isolation or in all their technically possible combinations: the wall is vertical, before fixing each doubling panel, the wall is marked to the right of the recesses to With the exception of the central recess, the said wall is pierced at the markings, then the plugs are inserted, the wall is horizontal (or more generally the wall is not vertical), before each doubling panel is affixed, the wall to the right of the central recess, said wall is pierced at the level of this mark and then inserted an ankle, after the fixing of each doubling panel, the wall is marked to the right of the remaining recesses of said doubling panel, it is disassembled and removing said lining panel from the wall, piercing said wall at these marks and inserting pegs, and then fixing said fountain board e that the head of each attachment means bears on the insulating panel, - is placed between the insulating panel and said wall, during attachment, a spring centered on the cylindrical rod of each attachment means, the head of each fastening means being isolated from the lining panel by a washer not coming into contact laterally with said lining panel, - the flatness of said lining panels is adjusted by means of screws and springs, the junctions are filled between doubling panels, recesses and expansion joints with flexible putty ready to be painted, - glue after drying of the flexible putty a painting with sharp joints offset from the doubling panel, - using height wedges j to create the joints of

  dilation when laying the lining panels.

  In various possible embodiments, the invention will be described in more detail with reference to the accompanying drawings in which: - Figure 1 schematically shows a section of an insulation device having a lining panel, according to one embodiment of the invention; FIG. 2 is a schematic representation of the laying of an insulation device comprising a lining panel on a wall, according to one embodiment of the invention; FIG. 3 is a schematic representation of a

  insulation device covering an entire wall, according to the invention.

  The wall insulation device 1 according to the invention comprises a lining panel 2 comprising an insulating panel 3. In a preferred embodiment, said insulating panel 3 is bonded to a gypsum board 4. Insulating panel 3 is made of a material such as flax, cellulose, mineral wool, sheep's wool, hemp, straw, polyurethane or polystyrene or a mixture of these materials. Fastening means 5 comprising a cylindrical rod 6 and a head 7 are used to fix said doubling panel 2. These fastening means 5 are, for example, screws, nails, etc. the terms "attachment means" or "screws" will be used indifferently to designate these elements. To fix said doubling panel 2, the head 7 of the fastening means

  bears on the insulation board 3.

  To further disconnect the insulating device of the wall 1 on which it is fixed so as to limit solid acoustic transmissions and thus achieve a better sound insulation, a spring 8 centered on the cylindrical rod 6 of each means d 5 may be placed between said insulating panel 3 and said wall 1. The spring 8 is for example metal, synthetic foam, rubber or any material having a fast shape memory. The spring 8 is recessed in its axis to the diameter of the cylindrical rod 6 to allow the passage thereof. This spring 8 advantageously allows the adjustment of the flatness while disengaging the insulation device from the wall 1.

  Similarly, the head 7 of each attachment means can be isolated from the lining panel 2 by a flat part 9. This flat part 9 is, for example, a washer centered on the cylindrical rod 6 of the fastening means. If the insulating panel 3 is rigid, the washer 9 is preferably made of rubber or any other material sufficiently flexible to fulfill its function of uncoupling but it can also be rigid and glued on the insulating panel 3 with a flexible adhesive, for example putty. When the insulating panel 3 is flexible, the washer 9 is made of rigid material, for example, metal.

  In a preferred embodiment, the lining panel 2 comprises at least three recesses 10 for receiving the fastening means 5. The lining panel 2 is then perforated twice concentrically for each recess 10. The first perforation It of diameter d is partial. Its diameter d is advantageously greater than that of the washer and its depth greater than a thickness composed of that of the plasterboard 4, the washer 9 and possibly the glue of the washer 9 and less than at least the thickness 2. In the case where the spring 8 is pre-assembled on the insulating panel 3, the diameter and the depth of the first perforation 11 must be greater than

  those of the spring 8, this to allow stacking.

  The second perforation 12 passes through the doubling panel 2 from one side to the other. It is of a diameter greater than that of the cylindrical rod 6 of the attachment means and of a smaller diameter than those of the spring 8 and the washer 9 overall. The diameter of the second perforation 12 is sufficient so that once the cylindrical rod 6 passes inside the washer 9 and the spring 8, it can not touch the edges

insulation board 3.

  The wall 1 may comprise at least three recesses 13 in which are placed pins 14 for receiving the fastening means 5. The set of fastening means is then completely separated from the wall 1 and the lining panel 2 qu she comes to fix. After fixing the lining panel, the recesses 10 made in the panel 2 for its attachment are closed with a flexible mastic. The sealant must be flexible to ensure good separation and ready to paint to allow the adhesion of the glue or the paint underlayment, when laying a canvas to paint. of the

  Acrylic putties perform this function perfectly.

  In order to always use pieces of lining panel with at least three fasteners (which allows adjustment of the flatness), it is necessary to start the assembly with a

  doubling panel piece defines as follows.

  To cover an entire wall of length L and width H using at least one insulation device of a wall comprising a doubling panel, as defined above, the procedure is as follows. The isolation device as a whole is placed on a useful wall of length L 'and width H' satisfying L '= L - 2j and H' = H - 2j, where j is the width of an expansion joint, each individual individual doubling panel being of width h and length I and comprising at least five recesses of diameter d, one central and each of the other four being centered on one side of said panel. In order to always use pieces of lining panel having at least three fasteners (which allows adjustment of the flatness), the dimensions of the first panel are defined in the direction of its length, then in the direction of its width, the editing is then started: - If there is an integer X such that (X + 1/2) I + 1/2 d <L '<(X + 1) I we start the assembly with an entire panel in the direction of the length. If such an integer X does not exist, the panel is cut lengthwise to obtain a length of

panel 1 '= (l + d) / 2.

  - If there exists an integer Y such that (Y + 1/2) h + 1/2 d <H '<(Y + 1) h. we start the assembly with an entire panel at the width. If such an integer Y does not exist, the panel is cut in the width direction so as to obtain a panel width

h '= (h + d) / 2.

  The set of isolation devices being placed on the useful wall 21, a flexible putty ready to paint comes to cover the junctions 27 between devices, the recesses 10 and the expansion joints 22. After drying the flexible sealant, a painting fabric 28 with sharp joints offset from the device is posed. This canvas also serves as calico. The painting fabric 28 is glued with a paint underlayment or with a suitable glue. The painting fabric 28 may be woven or not of glass, polyester, polypropylene or any type of sheet having sufficient internal cohesion to fulfill the calico function ready to paint. These sheets can be coated, printed, inked, complexed etc. The doubling panels 2 are fixed on the useful wall 21 with fastening means 5 comprising a cylindrical rod 6 and a head 7, said head 7 resting on the insulating panel 3 to fix the doubling panel 2. It can be sought disconnecting the insulation device from the wall 21 on which it is fixed so as to limit solid acoustic transmissions. A spring 8 centered on the cylindrical rod 6 of each attachment means is then placed between said insulating panel 3 and

  Said wall 21. The head 7 of each attachment means can be isolated from the lining panel by a washer 9 centered on the cylindrical rod 6 of the attachment means. In a preferred embodiment, the flatness of said panels is adjusted by means of screws and springs 8.

  When the wall 20 is vertical, one can mark the wall to the right of the recesses 10 with the exception of the central recess 20 before fixing each panel doubling. This step makes it possible to drill the useful wall at the marks to insert

ankles 14.

  When the wall is horizontal or more generally as soon as it is not vertical (especially in the attic), for example for a ceiling, it is advantageous to mark before fixing each panel 2, the wall to the right of the centrally recess, and then piercing said wall at this mark to insert a peg 14. The lining panel is then secured at the central recess and the wall is marked to the right of the remaining recesses of said liner panel. It is removed and then removed said doubling panel 2 of the wall 21 and pierced said wall at these new marks. Inserts 14 are inserted before fixing as previously described the panel so that the head 7 of each fastening means bears on the insulating panel 3. After the first panel has been fixed, the other lining panels 2 are applied. in order to cover the whole of the useful wall 21. Once all the panels have been laid, it is possible to adjust the flatness of the

  the set of insulation devices.

  The lining panels 2 comprise at least five recesses 10 so as to always have, in the case of a rectangular wall, at least three fasteners able to adjust

  perfectly the flatness of each piece of panel.

  Once the dubbing panels have been laid, a flexible putty 10 ready to paint is used to cover the perforations 10. The joints 27 between the panels, the recesses 10 and the expansion joints 22 are filled and then smoothed with a coating knife. Wedges 29 of height j can be used to create the expansion joints 22 during the installation of the panels 2. It suffices then simply to remove these wedges 29 after the panels have been laid, so as to make the expansion joints with flexible mastic. 22. This mastic is preferably an acrylic mastic. After drying said putty, it is possible to stick a painting to paint 28 with sharp joints staggered with respect to the panels

dubbing.

  Advantageously, the present invention avoids all work plaster based and sanding them.

  It also allows easy disassembly and reassembly without prejudice, neither for the insulation device, nor for the decoration of

the room.
