FR2783543A1 - Profiled component for lining ribbed wall - Google Patents

Abstract

The profiled component comprises on one side a concave shape complementary to that of a ribbing (4) of the wall. On the other side is a partially plane shape on which a lining component (2) is fixed. This side has a cavity in which the head (13) of a fixing screw (12), fixing the profile to the structure (5) supporting the wall, is engaged

Description

- 1 - The present invention relates to a profiled element for the lining

  of a wall, produced using ribbed elements such as corrugated sheets or profiled metal bins, for example made of aluminum or stainless steel of

all kind.

  It applies in particular to the production of overcoverings or overburdenings using doubling elements such as facing plates or even

  protection for example against noise and / or against solar radiation.

  In general, we know that the realization of an overcovering involves the installation of a supporting structure involving posts crossing the cover and an additional framework on which the elements of

overcover are fixed.

  It turns out that this solution is relatively complex, difficult to implement and is therefore expensive. It leads to a noticeable increase in the load-bearing structure of the cover and poses numerous sealing problems, in particular at the level of the crossing of the cover.

by the posts.

  Of course, the resolution of these sealing problems involves taking into account the phenomena of expansion which affect the roof as well.

  than the overcover elements.

  -2- The invention therefore aims in particular to eliminate these drawbacks and

solve these problems.

  To this end, it proposes, for the fixing of the lining elements, a profiled element having, on one side, a concave shape substantially complementary to that of a ribbing of the covering elements and, on the other side, a shape at the less partially planar on which can be fixed a lining element and comprising at least one cavity in which can engage the head of a fixing device used to secure the profile to the wall and / or

  on the frame element supporting said wall.

  Advantageously, the aforesaid second form may have a section in the form of an inverted O, the core of which is common with the soul of the first form, while the two parallel branches are terminated by two lateral wings which extend in the same plane. perpendicular in opposite direction from each other: These wings are used for fixing the lining elements. The cavity of this O-shape then accommodates the heads of the screws or rivets of

  fixing the profile to the cover.

  Of course, the invention also relates to a double wall structure

  using the above profiled element.

  Embodiments of the invention will be described below, by way of nonlimiting examples, with reference to the appended drawings in which: FIG. 1 is a view in vertical transverse section showing the assembly of a double wall on a warm blanket mounted on beams Figure 2 is a cross-sectional view of the profiled element used in the assembly of Figure 1; Figures 3 and 4 are partial vertical longitudinal sections (Figure 3) and transverse (Figure 4) illustrating the principle of assembly of an overcover on a cover laid in a "double skin" mounting (hot cover mounted on insulated tray) ; Figure 5 is a schematic section showing the mounting of an overcover on a corrugated cover using another alternative embodiment of the profile according to the invention; Figure 6 is a schematic section of an alternative embodiment of

  the profiled element according to the invention.

  In the example shown in FIGS. 1 and 2, the profiled element 1 according to the invention is used for fixing an overlay made up of flat facing elements 2, on a so-called hot cover comprising metal trays 3 (by example in prepainted steel) with ribs 4 of trapezoidal section. Eventually, the overcoverage could consist of

traditional blanket.

  This cover 3 is fixed to a frame comprising, conventionally,

  purlins 5 and trusses (not shown).

  In this example, the underside of the metal trays 3 covers a flexible or rigid thermally insulating coating 6 such as, for example, a plastic foam, a glass wool or the like or even a

  insulating felt covered with a vapor barrier film.

  The purlins 5 are here constituted by metallic profiled elements of IPE type, it being understood that they could be made of any other material by

wooden example.

  - 4 - Given the shape of the ribbing of the tanks, the profiled element 1 has, in its upper part, a transverse section in the form of an inverted n comprising a U-shape whose core 7 and the two branches 8 define a rectangular section channel CR and two lateral wings 9 which extend at right angles the two branches 8, opposite the core, in parallel

to this one.

  In its lower part, the profiled element comprises two oblique straight wings 10 which flare out, which extend the branches 8 opposite the wings 9 by delimiting with the core 7 a lower cavity CI of section

  trapezoidal in shape substantially identical to the section of the ribs 4.

  As illustrated in FIG. 1, the profiled elements 1 are placed directly on the cover and fit together thanks to the lower cavity C on the ribs 4, while the facing elements 2 are placed flat on the wings 9 and are there fixed for example with screws 11 or rivets

  expandable engaging in holes provided for this purpose.

  The fixing of the profiled elements 1 on the cover is, for its part, ensured by screwing by means of screws 12 (here self-drilling and self-tapping screws) which pass through holes made successively in the core 7 of the profile 1, in the face upper ribs 4 then in the insulating material 6 for

come and screw in the purlins 5.

  The head 13 of the screws 12 is then housed inside the channels CR and does not

  therefore does not constitute an obstacle to the installation of the facing elements 2.

  The sealing at the level of the bore produced in the ribs 4 of the tanks is ensured by means of a sealing gasket 14 disposed between the core 7 of the profiled element 1 and the upper face of the ribs 4. Of course, the - 5 - holes made in the profiled element 1 and the cover tanks 3 will be designed to allow a slight clearance in order to take account of the differential expansion, in particular between the profile elements 1 and the tanks 3. The seal 14 will therefore designed to ensure watertightness despite this play. Similar arrangements must be made at the end-to-end junctions of the profiled elements 1, the connection of two profiled elements 1

  by means of watertight couplings.

  Of course, the invention is not limited to the embodiment described above. So the blanket could consist of a cold blanket with or without

anticondensation.

  It could also, as shown in FIGS. 3 and 4, be placed on an insulating plate 15 constituted by ribbed plates 16, for example made of prepainted galvanized steel, provided with lateral assembly profiles 18, 19 which delimit with the plates a substantially parallelepiped volume containing an insulating material such as, for example, mineral fibers

or fiberglass.

  In this case, the fixing of the profiled elements is carried out by means of screws passing through holes made in parts overlapping the

  pairs of assembly profiles 18, 19 assembled together.

  In the example shown in Figure 5, the cover 20 is made of corrugated sheet. In this case, the oblique wings 21 of the profiled element 1 ′ may include curved shapes so as to conform to the undulations

of the cover 20.

  -6- Similarly, the shape of the part of the profiled element on which the facing elements are fixed, does not necessarily have a shaped profile

  of inverted Q delimiting a longitudinal channel.

  Indeed, as illustrated in FIG. 6, this part S of the profile could have a T-shaped section comprising a solid vertical central branch 22 extending the core 7 ′ and two lateral branches 23. In this case, blind holes 24 may be provided from place to place to receive the heads of the screws used for fixing the profiled element to its support

(frame or platform).

  Of course, the profiled elements according to the invention can be bent by

  so you can match the shapes of the cover.
