  WALL INSULATION DEVICE COMPRISING DOUBLING PANELS

AND METHOD FOR INSTALLING SAID PANELS

  The present invention relates to a device for isolating a wall comprising a lining panel and a method for laying said

doubling 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 floors

  insulation or the insulation under crawling roof ...

  They are then generally screwed on a metal frame of

  galvanized steel profiles. 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 to

isolation device.

  The fastening systems on metal framework strongly deteriorate the walls on which they are fixed (parquet, ceiling). They therefore do not allow disassembly without prejudice to the decoration of

the room.

  In addition, the fastenings on wooden cleats of the screw-in doubling panels rigidly secure the panel with respect to the support wall. Solid sound transmissions then degrade

  the acoustic insulation of the room.

  The panels glued 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 30 composed of doubling panels, or requires the fitter exceptional dexterity. The aim of the present invention is to propose a device for isolating a wall comprising a doubling panel and a method of laying dubbing panels, simple in their design and their operating mode, clean, removable, non-destructive for the building and

acoustically efficient.

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

  comprising a lining panel having an insulating panel, and fastening means for securing said panel, said fastening means having a cylindrical shank and a head.

  According to the invention, the head bears on the insulating panel for

  fixing said lining panel and the lining panel has recesses through which the head is introduced to bear against the insulating panel.

  In different embodiments, the present invention also relates to the following features which should 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 located at a distance from the edges of the doubling panel greater than their own diameter, - the front panel a length I and a larqeur h. at least three recesses are placed in a portion of said panel 1/2 length and width h / 2, a spring centered on the cylindrical rod of each fastening means is placed between said insulating panel and said wall, - the head each fastening means is isolated from the lining 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 attachment means, the wall comprises at least three recesses in which is placed a peg for receiving the fastening means, - the recesses made in the lining panel for fixing are closed with a flexible mastic, 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, such as defined above. 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 is the width of an expansion joint , each individual individual lining 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 a

sides of said panel.

  In order to always use pieces of doubling panel 10 having at least three fasteners (which allows adjustment of the flatness), according to the invention, and in the case where the recesses are at a distance from the edges of the doubling panel greater than their own diameter d, the dimensions of the first doubling panel are defined in the direction of its length, then in the direction of its width, the assembly 15 is then started: - If there exists an integer X such that X + 1/2) I + 1/2 d <L '<(X + 1) I we start the assembly with a complete doubling panel in the direction

of the length.

  If such an integer X does not exist, the first panel is cut lengthwise 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 editing with an entire doubling panel at the level of

the width.

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

doubling panel 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 at the right of the central recess, said wall is pierced at the level of this mark and then an ankle is inserted, after the fixing of each doubling panel, the wall is marked to the right of the remaining recesses of said doubling panel, dismantles and removes said wall panel from the wall, said wall is pierced at these marks and pins are inserted, then said wall panel is fixed; the head of each fastening 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 between panels are filled doubling, recesses and expansion joints with flexible putty ready to paint, - glue after drying of the flexible sealant a paint cloth with 25 sharp joints offset from the lining panel, - we use shims height j to create the expansion joints

  when laying the lining panels.

  Another method of mounting is possible when the recesses are positioned so that it is possible to cut in each elementary panel: at least a portion of length 1/2 and width h / 2 of said panel comprising at least three recesses, then - if there is an integer X such that

(X + 1/2) I <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, we cut the first panel in the direction of the length so as to obtain a panel length 1 '= 1/2 if there exists an integer Y such that (Y + 1/2) h <H '<(Y + 1) h. we start the assembly with an entire panel at the width, if such an integer Y does not exist, we cut the first panel in the direction

  width so as to obtain a panel width h '= h / 2.

  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 an 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 device

  insulation covering an entire wall, according to the invention.

  The insulation device of a wall 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 plasterboard 4. The panel Insulator 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 insulating panel 3 either directly,

either indirectly.

  To further separate the insulating device of the wall 1 on which it is fixed so as to limit solid acoustic transmissions 5 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 10 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 separating 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. The head 7 then bears against the insulating panel 3 indirectly by the flat part 9. This flat part 9 is for example, a washer centered on the cylindrical rod 6 of the attachment means. If the insulating panel 3 is rigid, the washer 9 is preferably of rubber or any other material sufficiently flexible to fulfill its function of separation but it can also be rigid and glued on the insulating panel 3 with a flexible glue, 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 11 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 30 of the glue of the washer 9 and less than at least to the thickness of the lining panel 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 has passed inside the washer 9 and the spring 8, the latter can not touch

the edges of the insulation board 3.

  The wall 1 may comprise at least three recesses 13 in which pins 14 are placed for receiving the attachment means 5. The assembly of the attachment means is then completely

  disengaged from the wall 1 and the doubling panel 2 that it comes 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 in order to allow the adhesion of the glue or the undercoat of paint printing, when laying a canvas to paint. Putties

  acrylics perfectly fulfill this function.

  In order to always use pieces of backing panel having at least three fasteners (which allows adjustment of the flatness), it is advisable to start the assembly with a piece of backboard.

Dubbing defines as follows.

  To cover an entire wall of length L and width H employing at least one wall insulation device 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 whole individual lining panel being of width h and of 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 and in the case where the recesses are at a distance from the edges of the doubling panel greater than their own diameter d), we define the dimensions of the first panel in the direction of its length, then in the direction of its width, the assembly is then started - If there exists an integer X such that (X + 1/2) I + 1/2 d <L '<(X + 1) I start editing with an entire panel in the lengthwise direction. If such an integer X does not exist, the first panel is cut lengthwise 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 panel at the width.

  If such an integer Y does not exist, we cut the first panel in

  the direction of the width 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 sub-coat of paint printing or with a suitable glue. The painting fabric 28 may be woven or non-woven 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 30. seek to separate the isolation device of 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 attachment means. In a preferred embodiment, the

  flatness of said panels by means of screws and springs 8.

  When the wall 20 is vertical, one can mark the wall to the right

  recesses 10 with the exception of the central recess before attaching each doubling panel. This step makes it possible to pierce the useful wall at the marks to insert pegs 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 pierce said wall at this mark to insert an anchor 14. The said doubling panel is then fixed at the central recess and the wall is marked to the right of the remaining recesses of said doubling panel. It is removed and then removed said doubling panel 2 of the wall 21 15 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. so as to cover the whole of the useful wall 21. Once all the panels are laid down, it is possible to adjust the

  flatness of the set of insulation devices.

  The doubling 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 perfectly adjust the flatness of each piece of panel.

  Once the dubbing panels have been laid, a flexible putty ready to paint comes to fill 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. Shims 30 29 of height j can be used to create the expansion joints 22 when laying the

  panels 2. Just then simply remove the wedges 29 after the installation of the panels 2 to achieve the flexible joints with the expansion joints 22. This sealant is preferably an acrylic sealant. After drying said sealant, it is possible to stick a painting to paint 28 with sharp joints 35 offset from the lining panels.

  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.
