Description

INSULATION PANEL MOUNTING SYSTEM FOR INSULATION

  ROOF AND PROFILE USED.

  The present invention relates to the insulation of sub-

  11 roofs using in particular self-supporting panels

  gloves based on mineral fibers and in particular, based

glass wool.

  It relates more particularly to a new system using a profile for mounting said panels between the structural members and the roof, as well as the

profile used.

  Insulation using insulating panels of the

  roofs of buildings and in particular buildings

  industrial, commercial, sports, etc., provides these buildings with thermal, acoustic and visual comfort, and different systems using profiles for mounting the insulating panels between the frame and the roof

have already been proposed.

  One of the known systems uses as profiles IPE beams already used as purlins in

  the frame, the lower bar of the I-shaped profile

  killing the support of the ends of the insulating panels,

  association with profiles of another type making of-

  fice of spacers between neighboring panels.

  One of the disadvantages of using IPE beams is their weight Another disadvantage is the limitation

  in the choice of the dimensions of the IPE.

  To overcome these drawbacks, it has already been proposed to use purlins and rails made of folded or profiled Z-shaped sheet which provide a weight saving of about 50%.

compared to IPE failures.

  A drawback of using Z-shaped metal purlins is that this profile shape does not have supporting surfaces or edges allowing the direct mounting of the insulating panels on the profile. Additional elements must then be used as a support. , these elements being themselves supported by jumpers overlapping the Z-section, or else screwed as described in US 4,375,742 on the underside of the Z-section.

  The use of additional elements and the operations

  mounting rations greatly increase the cost

under-roof insulation.

  The invention provides a new system comprising a

  profile acting as purlin or smooth, this system

  putting to support the insulating panels at the level

  which is particularly easy and quick to install.

taller.

  The system according to the invention for mounting the pan-

  self-supporting insulating elements comprises a profile having a central core ensuring rigidity and determining the height of the profile, extending between two parallel bases, the lower base allowing the profile to be fixed to elements of the frame, the upper base allowing the fixing of the cover on the profile, and two wings

  extending on either side of the profile core and per-

  putting to support the insulation panels at level

  desired under the roof covering.

  The upper level of the wings belonging to the system, corresponding to the support line of the insulating panels, is determined by the thickness of the insulation to be used and by the total height of the profile, and so that the difference in level between the support line and the upper cover receiving base, increased the case

  thickness of an interlayer or a joint between

  tre this cover and the profile, is substantially equal

  the thickness of the insulation to be used.

  In one aspect of the invention, the mounting system essentially comprises a profile having two

  wings extending on either side of the soul.

  According to an embodiment of this aspect of the invention, the profile has the shape of two opposite Z and joined with

  raised lower ends forming the two wings.

  In this embodiment, the core is formed of two substantially vertical and substantially parallel sides, connected

  at their upper ends by a flat surface cor-

  corresponding to the upper bars of the Z and forming the upper base of the profile, the lower base being 1.5 it constituted by the lower bars of the Z.

  This profile can be formed advantageously and easily-

  by profiling or bending a thick sheet

  suitable, especially galvanized steel sheet.

  In an alternative embodiment of the profile, it has the shape of an I, the base of which is provided with two raised wings such as a double hook shape, and of which

  the core is made up of two thicknesses adjoining ma-

  face, in particular a sheet as in the pre-

  cedent. Advantageously, the profile has a symmetry which

facilitates installation.

  In one advantageous aspect of the invention, the profile has a nestable shape which facilitates its

  packaging and its transport Thus, in the realization

  tion that the profile has the sensitive shape-

  ment of two adjacent and opposite Z's, the two flanks constitute

  kills the rigid core have a flared shape down

which allows said nesting.

  In another advantageous aspect of the invention, the

  profile has specific structural characteristics

  putting to fix, in particular by clipping on its wings,

  a cover covering its lower part.

  In addition to the aesthetic function, the cover allows

  keep any sheath or wire in the body of the profile.

  Under the hood or integrated into its structure may be provided lighting means The hood may be transparent or

  translucent and be part of a light system.

  In the variant where the core is formed by two separate sides, the space between these two sides can be filled with a fire retardant material, maintained where necessary by

the hood.

  In another aspect of the invention, the mounting system consists essentially of the profile and of a cover 0 of a shape suitable for its mounting in particular by clipping onto the base of the profile, the walls of the cover extending beyond the level from the lower base of said profile, thereby forming the wings extending on either side of the core of the profile and intended to support the insulating panels at the desired height. Under this aspect of the invention, the profile can then

  present a simplified structure, able to fill single-

  the mounting function of the cover on the char-

  slope and the hood hold function, the latter as-

  ensuring the support function of the insulating panels at the

desired height.

  Advantageously, the cover is provided with means

  putting its assembly in particular by clipping, at different

  levels, depending on the height of the profile and the thickness

of the insulation used.

  Thus, the cover can have on these two walls two series of ribs allowing its fixing by clipping

  on the lower base of the profile.

  According to one embodiment of the invention, the mounting system is used for a so-called "hot roof" insulation using self-supporting insulating panels, and it comprises the profile described above and the two wings

  support of the panels as well as a wedge or strip, preferably

  made of a rigid and insulating material, arranged at the

  placement of the reception of the roof and which has a structure making it possible to maintain the end of the insulating panels by pinching between said strip and the wings of the

  system, either from the profile or from the cover.

  Other advantages and characteristics of the invention

  will appear in the following description of examples of

  achievements of the insulation panel mounting system

  according to the invention made with reference to the figures.

  Figure 1 shows in a perspective view a profile essentially constituting the mounting system

  according to the invention, used as a purlin for an iso-

lation under roof.

  Figure 2 shows in perspective a variant of

  profile used in the mounting system according to the invention

  Figure 3 shows in perspective another variation.

  laughing profile used in the mounting system according to the invention. Figure 4 shows in section, the profile according to Figure 1 provided with a cover. Figure 5 shows a variant of the mounting system according to the invention comprising a profile and a cover

  whose wings support the insulating panels.

  FIG. 6 represents, in a perspective view,

  a mounting system for insulating panels according to the invention

  tion using a profile according to Figure 1.

  Figure 7 shows a section of the

  mounting of the insulating panels shown in figure 6.

  Profile 1 shown in Figure 1 has the general shape of two Z 2, 3 opposite and joined The core 4 of the profile consists of two sides 5, 6 slightly inclined relative to the vertical plane p in the figure which is a plane of symmetry, being flared downward, so as to allow the profiles to fit together during their packaging and transport The two sides 5, 6 are

  connected by an upper base 7 adapted to receive the cou-

  groove (not shown) after interposition or not of a

strip of insulating material.

  The lower ends of the two sides are pro-

  bordered by two horizontal parts 8, 9 forming the lower base 10 parallel to the upper base 7 These two horizontal parts 8, 9 constituting the lower base 10 are intended to bear on the elements of the

frame of the building to be insulated.

  Two wings 11, 12 oriented upwards extend the

  lower base 10 These wings 11, 12 are intended for sup-

  wear the insulating panels not shown in this figure

  gure The height of these wings 11, 12 is determined by the thickness of the insulation that it is desired to use and by the total height of the profile, knowing that the thickness of

  the insulation corresponds substantially to the difference h of ni-

  calves between the upper ends 13 of the two wings and

the upper base 7.

  When using a spacer, for example a strip of insulating material between the cover and the upper base of the profile, the thickness of the insulation corresponds to the difference in levels between the end of the wings and

  the upper base, increased by the thickness of the interca-

laire.

  The thickness of the insulation is for example 50 mm or

80 mm.

  The wings 11, 12 are preferably inclined outwards relative to the vertical plane p. One of the advantages of the shape shown in Figure 1 is that the two wings 11, 12 in addition to their function of supporting the insulating panels, determine in cooperation with the sides and the lower base, two gutters 14, which can be used for passage of sons

electric for example.

  The profile can be easily manufactured by profiling a sheet, preferably in galvanized steel. The thickness of the sheet can vary according to the dimensions of the profile and

  the loads it has to bear The thickness is gener-

rarely between 1 and 4 mm.

  The section 16 shown in Figure 2 is a va-

  laughing of the profile shown in Figure 1 In this

  variant, the shape of which recalls an I having an in-

  lower extended by two wings, the core 17 is constituted

  two flanks joined 18, 19 The upper base 20 cor-

  corresponds to the upper bar of the I The fixing of the cou-

  the profile can be made on one side or the other

  tre of the vertical plane of symmetry containing the core 17 The lower base 21 is constituted by the lower bar of the I This base 21 is extended by two wings 22, 23 oriented upwards, as in the case of the profile described

  in relation to figure 1 This form also presents

two gutters 24, 25.

  The insulating panels shown in phantom are placed in this variant between the end 26 of the wings 22, 23 and the upper bar of the I, as shown in the figure. Figure 3 shows another variant of the profile

  belonging to the system according to the invention In this va-

  laughing profile 27 which takes the general shape of the profile

  yarn shown in Figure 1, the junctions 28, 29 between

  the upper base 30 and the two sides 31, 32 are in-

  clinched outwards, which makes it possible to maintain the insulation panels shown in phantom by pinching between the upper base 30 and the two wings 33, 34 extending from the lower base 35, formed of

two parts 36, 37.

  Figure 4 shows a profile 1 as described in connection with Figure 1 provided with a bottom cover 38 which

  is mounted by clipping on the two wings 11, 12 of the pro-

  spun In addition to an aesthetic function, such a cover 38 can be used to hold in the profile different materials, in particular fire-resistant materials.

  base 39 and two flanks 40, 41 in flared shape for

  see fit to the profile wings can be transparent

  and in this case be part of a lighting device.

  In Figure 5, there is shown a mounting system according to the invention comprising a profile 42 and a cover 43 in a U acting as a support for the insulating panels 44 shown in phantom The profile 42 comprises an upper base 45 on which is fixes the cover using screws 46, a core 47 consisting of two sides 48,

  49, and a lower base 50 which is fixed on the frame.

using screws 51.

  The ends of the lower base support a cover 43 which is provided on each of its two walls 52,

  53 which form the wings of the system, of a series of nerves

  vures 54 allowing the mounting of the cover at the desired level with respect to the lower base 50 of the profile The mounting level is a function of the height of the profile and of

  the thickness of the insulating panels used.

  In Figures 6 and 7, there is shown the mounting system using profiles described in relation to Figure 1, in an insulation structure with "hot roof" that is to say without free air space between the cover 55

and the insulating panels 44.

  The profiles 1 are fixed to structural elements, for example metal beams 56 using screws 57 which pass through holes provided in one or both

parts of the lower base 10.

  Profiles 1 act as purlins and are available

  laid at regular intervals corresponding to the length

  insulation panels which are here based on mid wool

  mineral and self-supporting These panels are for example rigid panels of glass wool 58 impregnated with resins,

  reinforced with a glass veil and surfaced with aluminum kraft

  minium lacquered 59 such as those marketed under the name

  lation SHEDISOL by ISOVER SAINT-GOBAIN These panels are placed on the upper edges 13 of the wings 11, 12 of the profile 1 A strip 60 of a material

  rigid insulation is placed on the upper base 7 of the pro-

  spun 1 and preferably it has a trapezoidal section

  zoidal 61 so that the sides 62, 63 of the trapezoid 61 come to rest like corners on the upper edge 64

  insulating panels 44 These panels 44 are thus

  firmly held by pinching between the wings 11, 12 of the profile and the rigid strip 60 The cover 55 is placed on the rigid strips 60 and fixed with screws 65 on

  the upper base 7 of the profiles 1, which for this purpose pre-

  feel holes for the passage of screws in the appropriate locations. The insulating panels 44 can thus be installed at the same time as the cover 55. Between the panels 44, in the direction perpendicular to the profiles 1,

  other profiles known per se and not shown, desi-

  generally reached by spacers and which like the panels

  of insulation rest on the wings 11, 12 of the profiles 1.
