Description

The present invention relates to mounting and

  fastening a thin insulation (14) to a U-shaped metal channel (10) of a metal framework used to insulate a roof, walls or walls of buildings.

  Many fastening systems of this type of thin insulation (14) are known, for example, laying a roof under battening when there is complete renovation thereof, laying under the rafters (17) a roof made of stapling the thin insulation under them, however when using this type of thin insulation (14) for the insulation of a roof without disassembly thereof, it is difficult to isolate between the roof and the metal frame without creating an air passage due to the passage of the fastening elements of U-shaped metal profiles (10) under the frame, which is not recommended for effective insulation with this type of thin insulation (14). ).

  To overcome this problem, it is necessary to use an insulation installation mode to create a completely sealed envelope of the thin insulation (14) between the facing (15) and the U-shaped metal profiles (10).

  The invention therefore relates to the system (1) for quickly achieving this method of installation quickly, this mounting and fixing system comprises the following essential elements: A metal plate called mounting plate or spacer (2) ribbed in its length (9) for fixing the thin insulation (14) to the U-shaped metal section (10).

  - Holding flanges (3.5.7) located on the periphery of the plate (2), pointed allowing easy drilling the thin insulation (14) with their ends.

  - Fastening lugs (4.6.8) located at the end of the holding flanges (3.5.7) allowing the fastening on the returns (11.12) of the U-shaped metal section (10) by clipping the system onto the metal section. U (10). (see figure 2/3).

  The plate (2) has two ribs (9) directed towards the thin insulation (14) in the longitudinal direction in order to ensure the rigidity to the system during the clipping of the thin insulation (14) on the metal section. U (10).

  This system makes it possible to perform the following functions: The fastening function of the system allows a connection to be made between the thin insulation (14) and the U-shaped metal section (10).

  - The spacer function of the plate (2) of the system (1) allows the attachment point (16) to create between the facing (15) and the thin insulation (14) a rigid surface identical to that of the metal section U-shaped (10) allowing a good fixing of the facing (15) on the U-shaped metal section (10) without risk of degradation of the facing (15) because the thin insulation (14) is flexible at the point of attachment (16), in fact the facing deteriorates at the point of screwing (16) when screwed onto a flexible surface.

  A last function, see Figure 3 ensures, when laying contiguous plates (15a, 15b) at a metal section U (10) of a metal frame, a leveling of the plates. The fastening system (1) between the thin insulation (14) and the U-shaped metal profile (10) makes it possible to create a rigid surface (2b) at the level of the recovery of the plates (15a, 15b), which makes it possible during screwing (16b, 16c) of the two contiguous plates to ensure horizontal leveling of the two plates (15a, 15b) by eliminating the flexibility of the thin insulation (14) which facilitates the implementation of the finishing product because the lack of flatness is reduced.

  The fastening system (1) will be placed at each fixing point (16) of the facing (15) on a U-shaped metal channel (10).

  The shape and dimensions of the fastening system (1) provided with these holding flanges (3.5.7) with at their ends clipping lugs (4.6.8) depend on the U-shaped metal section (10) forming the metal frame and can be formally determined by a U-shaped metal profile (10) of given dimensions.

  Its manufacturing thickness will be in 5 / 10th mm and 7 / 10th mm galvanized sheet. The holding flanges (3.5.7) of the plate (2), bent at 90 are slightly wider than the metal channel section (10) so that the flanges (3.5.7) can wrap the sides (17.18) of the profile U-shaped metal (10) and that the lugs (4.6.8) located at the ends of the holding flanges (3.5.7) bear on the returns (11.12) of the U-shaped metal section (10).

  The length of the plate (2) will be about 80 to 90 mm.

  The length of the holding flanges (3.5.7) provided with their lugs (4.6.8) must take into account the thickness of the thin insulation (14) used, knowing that it will have to undergo a slight compression, thus avoiding a risk of play between the facing (15) and the U-shaped metal profile (10) during screwing.

  The remarkable advantages provided by the invention of this fastening system (1) are as follows: Firstly, avoid the installation of a system for fixing the thin insulation (4 on the U-shaped metal section (10). ) In addition, it ensures a good maintenance of the insulation without the risk of seeing the thin insulation {14) unhooking the U-shaped metal section (10) even on a large surface.

  On the other hand, the plate (2) by its spacer function provides a rigid surface in contact with the thin insulation (14) which allows a screwing (16) of the facing (15) without deterioration thereof.

  The manufacture of this type of system (1) is to stamp a metal sheet automatically so as to give it the desired shape, before galvanizing, simple and fast realization on an industrial scale.

  Fixing the thin insulation (14) on the U-shaped metal section (10) is obtained in a simple manner by interlocking the fastening system (1), which passes through these pointy holding flanges (3.5.7). thin insulation before coming clipped through its lugs (4.6.8) on the metal channel U (10) of the metal frame.

  The holding flanges (3.5.7) ensure a slight tightening after clipping on the sides (17.18) of the U-shaped metal section (10) so that the lugs (4. 6.8) are in connection with the returns (11.12) of the metal profile. in U (10).

  Other features and advantages of the invention will appear in the description of the accompanying drawings in which: Figure la schematically shows a first embodiment of the system (1) according to the invention for perspective.

  Figure lb is a sectional view along aa of Figure la.

  Figure 2 is the representation of the fastening system with the thin insulation (14) pinched between it and the U-shaped metal section (10).

  FIG. 3 is the sectional representation of the installation that can be made of the system according to the invention for isolating a roof.

  Referring to Figure la and lb, the plate is composed of 3 holding flanges (3.5.7) with clipping pins (4.6.8) at their ends.

  Referring to Figure 2/3 where the fastening system (1) is applied to the thin insulation (14) above the U-shaped metal profile (10), with a hand pressure the fastening system perforates the thin insulation (14) by its holding flanges (3.5.7) until the lugs (4.6.8) are hooked on the returns (11.12) of the U-shaped metal section (10).

  FIG. 3/3 shows an insulation method using the fixing and spacer system according to the invention for an insulation under a roof: this involves insulating a roof with a thin insulation (14) placed between the metal framework (10a.10b.10c) and a gypsum board facing (15a.15b).

  To achieve this insulation, we put in place the fixing lines (13a.13b.13c) on the rafters (17) by screwing. On these lines (13a.13b.13c) is clipped the U-shaped metal sections (10). Once all the metal framework is achieved, we put in place the thin insulation (14) by fixing it by the fastening system (1). The fastening systems will be arranged at each point of screwing (16a.16b.16c.16d) gypsum board (15a, 15b) on the metal frame. Once the insulation (14) is installed I0 using the fixing system (1), position the drywall (15a.15b) on the thin insulation (14) and put in place the fixing screws (16a.16b.16c16d) at the location of each fastening system (1).

  When screwing the screws for fastening plasterboard (15a.15b), there will be no degradation of the plasterboard due to the rigidity of the plates (2a.2b.2c) serving as a rigid spacer, the screws will fit to the desired depth in the facing (15), and it will remain only to proceed with the implementation of the finish without being bothered by the screw heads.

  The invention thus provides a mounting system and particularly reliable and quick to implement and easy to use.
