Description

DESCRIPTION

  1 The present invention, called a multifunction snap-in element, relates to a device to be used in the field of roof insulation of industrial buildings, when this insulation is made of rigid panels of glass wool, or rock wool. This insulation can be installed, either between the metal purlins of the building frame, or suspended under

failures.

  According to the current technique, the installation between purlins is carried out as follows: the rigid panels, in glass wool or rock wool, rest on the lower wings of the purlins. A metallic T-shaped connecting spacer, fixed by anti-lifting parts fitted at the end, is placed between each panel. These panels are held by holding latching elements,

attached to the spacers.

  The installation under purlins is carried out in the following way: a framework, composed of load-bearing profiles and metallic spacers, in the shape of a T, is fixed to the purlins using hangers. The insulating panels are held in the profiles by means of fixed retaining elements

on the frame.

  The standard thickness of glass wool panels,

  or rock wool, used to insulate industrial roofs

  trielles, is 40 mm, 50 mm or 80 mm. In addition, double-walled polycarbonate panels, thickness 6 mm, are used for doubling roof lighting, when it has one.

daylight.

  The implementation of insulation, according to the techniques described above, comprises the following essential points - suspension of the framework; - maintenance of insulating panels and lining panels for roof lighting, in the metal framework; 1 - anti-lifting of the assembly, in the event of gusts of wind: significant (industrial buildings often have large doors requiring frequent opening; special attention must therefore be paid to this problem of raising the insulation, in the event of atmospheric turbulence). To meet the requirements formulated above, in terms of holding the panels, it is necessary to use several parts: anti-lifting snap-in elements, placed in the purlins of metal frame; - snap-in elements for holding polycarbonate lining panels; - snap-in elements for holding the insulating panels,

  made up of two parts which fit into each other.

  The device according to the invention makes it possible to meet these requirements with a single multifunction piece, which acts as a locking element for holding the insulating panels and for the polycarbonate lining panels, and anti-lifting locking element for .all

insulation + framework.

  The multifunctional snap-in element can be snapped onto a load-bearing profile, or onto a spacer,

  constituting the mesh intended to receive the insulation.

  This multi-functional snap-in element is designed to

  exercise the function of snap-on latching

  insulated, thanks to two foldable sides on the

  insulating panels, thickness 40 mm, 50 mm or 80 mm.

  It is also designed to be used as a 3rd ratchet element to hold an insulating panel, 40 mm, 50 mm or 80 mm thick, and a panel for lining a roof light, including the thickness is 6 mm. To date, there is no system allowing the use of a single retaining latching element, 5 due to the difference in thickness between the insulating panel and the lining of the roofing light. The system we present solves the disadvantage of the difference

  thick, and avoids the use of two enclosure elements

  different holding quilting (one for the insulating panel, 1 thickness 40 mm, 50 mm or 80 mm, and one for the

lining, thickness 6 mm).

  The multifunction snap-in element can also be used as an anti-lifting snap-in element thanks to these pre-cuts designed for purlins of dimensions mm, 120 mm, 140 mm and 160 mm (usual dimensions for purlins of metal frames). These pre-cuts make it possible to cut the anti-lifting latching device at the desired height, and to come and block it in the failure of the frame. Reinforcement grooves are provided on the part in order to stiffen it, and to avoid the weak point of the precuts. The accompanying drawings illustrate the invention: - Figure 1 is a side view of the multifunction snap-in element; - Figure 2 is a front view of the multifunction latching element; - Figure 3 shows a carrier profile; - Figure 4 is a perspective view; - Figure 5 shows the multifunction latching element used as a latching element for holding an insulating panel, and a polycarbonate lining panel; FIG. 6 shows the multifunction snap-in element used as a snap-fastening element for holding two insulating panels - FIG. 7 shows the multifunction snap-in element,

  seen from the front, used as an anti-snap element

  lifting of the insulation + metal frame assembly (anti-lifting latching element blocked in the metal breakdown), and placed as a latching element for holding insulating panels;

  FIG. 8 represents a profile view of FIG. 7.

  For the understanding of the comments on the drawings, we start with Figure 3: it represents a support profile 10, or a connecting spacer, constituting the mesh of the false ceiling, on which will be placed the multifunction snap-in element. Part 11 of the supporting profile 10 is a bead, intended to hold the various fixing parts used, and to stiffen

the soul of the wearer.

  1. In Figure 1 (side view), the lower part of

  the multifunction snap-in element has three half

  snap-in elements (two are visible in the side view): two fixing snap-in half 2, only one of which is visible in the side view, at the base of which is placed an engaging tab 4, to facilitate the engagement on the bead 11 of the carrier profile 10, and a fixing snap half-element 1, which has, at the base, an engagement and holding tab 5 for polycarbonate panel. The two snap-in half elements of

  fixing 1 and 2 are fixed by pinching on the stuffing

  let 11 of the bearing profile 10. The two half-elements of enclosure

  fixing quet 1 and 2 include retaining lugs 3 providing them with support reinforcement at the bead

  11. The upper part of the multi-latching element

  function constitutes an anti-lifting latching element

  of the insulating panels + framework, thanks to the pre-

  cut-outs 7 which allow the multifunctional snap-in element to be broken at the precise height, calculated to enter inside of purlins of framing of 100 mm, 120 mm, 140 mm or 160 mm (external dimensions). Reinforcement grooves 8 are produced by stamping, to stiffen the part, and avoid the weak point at the precuts. We see in 6 the legs of

  folding intended to fix the insulating panels.

  Figure 2 is a front view of the room, where one

  distinguishes, in the lower part, the two half-elements of enclosure

  fixing quetting 2, with their engagement tab 4, and the

  retaining pins 3. We also see the half-element

  quêtage 1, comprising an engaging and retaining tab 5.

  This tab 5 has a length studied so as to come main-

  hold a polycarbonate panel on a support profile 10 (this function is visible in Figure 5, to which we will return later). The fixing snap-in half 1 also includes a retaining lug 3. The upper part of the multifunction snap-in is composed

  two parts, since there is a separation slot 9.

  This slot 9 is intended to allow the parts 6, called the folding tabs, to be folded down, on the left and right side,

  in order to maintain the insulating panels. This function of elec-

  ment of retaining insulating panels 1 is visible in figure 6. In the case where there is an insulating panel 12, on one side, and a polycarbonate panel 13, doubling a roof lighting , on the other side, the two parts 6 are folded down on the insulating side (see FIG. 5). Breakable precuts 7 are placed on the part in order to allow it to be cut to the precise height, calculated to enter inside purlins of 100 mm, 120 mm, 140 mm or 160 mm (external dimensions), and make enti-lifting function of the entire insulation (panels + framework). Reinforcement grooves 8 are produced by stamping, to stiffen the part, and avoid the weak point at the precuts. Figure 4 is a perspective view of the element

  multi-function locking mechanism described in Figures 1 and 2.

  A distinction is made between the fixing snap-in half elements

  2, with their engagement tab 4, and the retaining pins 3.

  We also see the half-latching element 1 with engaging and retaining tab 5 of a polycarbonate panel 13. The engaging and retaining tab 5 also includes a retaining lug 3. These retaining lugs lock in the bead 11 of the carrier profile 10, ensuring the solidity of the attachment. We see, in the upper part, the slot

  separation 9, folding legs 6. We can also see

  Likewise the breakable precuts 7, and the throats of -renfor-

cement 8.

  Figures 5 and 6 show the snap-in element

  multifunction used as a retaining snap element.

  In FIG. 5, the multifunction latching element is used as a latching element for holding a panel: insulation 12, and a polycarbonate panel, thickness 6 mm, doubled with a roof light. The tab 5 holds the polycarbonate panel 12 which rests on the support profile 10. The insulating panel 12 is held by the folding tabs 6. The tabs are folded on the same side on the insulating panel 12, ensuring its maintenance and the aesthetic appearance . These tabs are not visible from the polycarbonate panel side. The device according to the invention therefore reconciles the fixing of two panels with a thickness

different.

  1 In FIG. 6, the multifunction latching element is used as a latching element for holding insulating panels 12. The engagement and holding tab 5 is embedded

  in the glass wool panel, or rock wool 12.

  The insulating panels 12 rest on the support profile 10,

  and the parts 6 are folded down, on each side, on the pan-

  insulating sleeves 12, ensuring their maintenance.

  In these Figures 5 and 6, we see a half-click element

  stage 2 with engagement tab 4, the half snap-in element

  1 with engaging and holding tab 5 of the polycarbonate panel

  bonate. We see the retaining pins 3 locking on the

bead 11 of the support profile 10.

  Figure 7 is a front view of the enclosure element.

  multifunctional quetting used as an anti-snap element

  lifting of the entire insulation + framework, and

  retaining clip.

  To the right of Figure 7, the multi-latching element

  function has been broken to the desired size, thanks to the pre-

  cutouts 7, and it is used in anti-lifting in a breakdown

14 of 100 mm (external dimension).

  In the central part of FIG. 7, the multifunction snap-in element is seen from the front, snapped onto a bearing profile

  , depending on the locking snap element.

  Figure 8 is the side view of the device described

in figure 7.

  The device thus described finds its application in

  the field of roof insulation for industrial buildings.

  Its innovative aspect resides in the fact that a single piece combines several functions (containment element for holding insulating panels and roofing lining doubling panels, in insulation between purlins or underpanes, ratcheting element d anti-lifting of the insulation + frame assembly in insulation between purlins). The system is also innovative in that a single piece can hold two panels of different thicknesses,

  which did not previously exist.
