Description

o central screw for fixing to the adjustment bracket (2).

  The present invention relates to a cladding profile, or tray, and to a wall or roofing wall for a building, produced by an assembly of

such trays.

  We know from patent application FR 97 14782 filed in the name of the applicant a plate capable of constituting a wall element, comprising a pad, means for supporting a counter-cladding, and fitting means adapted to restrict movement relative of adjacent trays in a direction

  substantially perpendicular to said range.

  There is shown in Figure 1 such a plate H. As can be seen in this figure, the means for supporting a counter-cladding (not shown) comprise two wings a 1, 2 extending substantially on the same

  height h from range 3.

  As clearly appears in FIG. 2, where two nested plates D1, D2 have been shown, the abovementioned nesting means are obtained thanks to

  a particular geometry of the wings a1, a2.

  The wing a1 of the plate H1 indeed has a spout 1 which comes to bear on an inclined face 2 of the wing 2 of the plate D2, and a lip \ 1 which comes to rest under a lip X2 of the wing 2 of the plate n2, which makes it possible to restrict the relative displacements of the plates H1, H2 in the two directions of the direction dl perpendicular to the

tracks 31, 32.

  As taught by patent application FR 97 14782, this restriction of displacements makes it possible to maintain the lips \ 1, X2 contiguous during the fixing of a counter-cladding, without it being necessary to resort to fast techniques idious and expensive like

  than the "stitching" of the beaches of the plateaus.

  Although it offers satisfaction in many respects, this tray of the prior art has a geometry which makes its stacking particularly bulky. In such a stack, in fact, as shown in FIG. 3, the plates Ul, H2 are

  grouped in pairs and placed in opposition.

  Although such an arrangement makes it possible to obtain a certain stability, particularly desirable in particular for the storage and transport of the trays, it can easily be seen that the height of a stack of 2n trays of height h is substantially equal to nxh, this who is

quite considerable.

  We therefore find ourselves in a situation where the volume stored or transported is mainly occupied by vacuum, that is to say by spaces E (see Figure 3)

  located between each pair of trays l, H2.

  This ultimately results in high storage and transport costs relative to the amount of material

actually transported.

  It will also be noted that in order to place the plates Ul, H2 in opposition in accordance with FIG. 3, manual intervention is necessary, by which one plate out of two leaves out of the chain of

production.

  This manual intervention weighs heavily

production costs.

  Similarly, when the trays arrive on site, significant handling is necessary to recover

each tray.

  The object of the present invention is to overcome the

disadvantages mentioned above.

  This object of the invention is achieved with a plate capable of constituting a wall element, comprising a pad, means for supporting a counter-cladding, and fitting means adapted to restrict the relative movements of adjacent plates in a direction. substantially perpendicular to said area, remarkable in that said support means comprise a single wing connected to said area, and in that said interlocking means comprise on the one hand an edge of said area opposite to said wing, and on the other hand, a fold formed in said range extending at the

vicinity of said wing.

  The nesting function is therefore ensured by the track itself, so that it is no longer necessary to provide, on each plate, pairs of wings of complementary shapes. We can in particular choose to keep only one wing, which gives each tray an asymmetry defining a very open volume particularly conducive to compact stacking, no longer requiring to place the

  opposing panels for transport.

  According to other characteristics of the invention: - said wing comprises a doubled lip, - said wing comprises a doubled foot, - said pad is partly doubled, - said edge is folded back on itself, - said fold is distinct from said wing and inclined relative to said range, - said plate further comprises a rib formed in said range and defining with said wing a stop adapted to restrict the relative movements of adjacent plates in a direction substantially parallel to said range, - said fold is formed at the junction of said beach

and of said wing.

  The present invention also relates to a wall for a building wall or roof, remarkable in that it comprises cladding formed of an assembly of

  trays in accordance with the above.

  According to other characteristics of this wall: - it comprises a counter-cladding fixed on the wings of said plates, the lines of joints of said counter-cladding being substantially perpendicular to those of said cladding, - it comprises a counter-cladding fixed on the wings said plates by means of spacers, the lines of joints of said counter-cladding being substantially parallel to those of said cladding, - a layer of insulating material is placed in said cladding, - a layer of insulating material is interposed between

  said cladding and said counter cladding.

  Other features and advantages of the invention

  will appear on reading the description which follows

  and on examining the appended drawing, in which: - Figures 1 to 3 represent trays of the state of the art, described above, Figure 4 is a sectional view of a first embodiment of the tray according to the invention, - Figure 5 is a sectional view of an interlocking of two trays according to Figure 4, - Figure 6 is a sectional view of a stack of four trays according to Figure 4, and - Figures 7 to 9 are views similar to Figures 4 to 6 respectively, for a second mode of

  realization of the tray according to the invention.

  In these figures, award-winning references (that is to say followed by the sign "prime") deign bodies or sets of bodies identical or similar to those

  deigned by non-award winning references.

  Referring to FIG. 4, in which we see that, according to a first embodiment, the plate P according to the invention comprises a single wing al connected to a

range a3.

  The wing al comprises a foot p slightly inclined relative to the direction dl perpendicular to the range a3, and a lip L extending towards the outside of the plate P.

  in a direction substantially parallel to the range a3.

  The foot p and the lip L are preferably doubled, the doubling being obtained by folding the wing al

on herself.

  The plate P also comprises a fold 3 formed in the range a3 at the junction of this range with the wing al, and pointing towards the inside of the plate P. Opposite the wing al, the plate P comprises a edge 5 folded so as to define a complementary nesting with fold 3, as can be seen in FIG. 5, ol 'there is shown a nesting of two

adjacent plates P1, P2.

  Each tray P can also include a

  plurality of longitudinal reinforcements 7, 9 (see Figure 4).

  Referring to FIG. 6, it can be seen that when plates P1, P2, P3, P4 are stacked, the feet p of their wings al are placed side by side, and the range a3 of each of them rests both on the fold 3 and on edge 5

of the lower plate.

  Reference is now made to FIG. 7, in which a second embodiment of the plate P ′ according to the invention has been shown, the description of which will be limited to

  differences from the previous embodiment.

  Preferably, as shown, the wing has folded back on itself so as to double the lip

  The, the foot p 'and part of the beach a3'.

  The fold 3 'is distinct from the wing a', and inclined by

  relative to the range a3 ', preferably about 45.

  The edge 5 ′ is folded so as to define a complementary nesting with the fold 3 ′, as shown in FIG. 8, where a

  interlocking of two adjacent plates Pl ', P2'.

  Each plate P 'has a locking rib ll' formed in the range a3 'and defining with the wing has a stop adapted to restrict the relative movements of the plates Pl', P2 'in a direction d2 substantially parallel to the range a3 '' (see figure 8), as well as a

longitudinal reinforcement 7 '.

  Referring to FIG. 9, it can be seen that when plates Pl ', P2', P3 'are stacked, their folds 3' and their ribs ll 'fit together, so that their wings have', their ranges a3 'and their 5' edges are

noticeably joined.

  In the first as in the second embodiment which have just been described, the plates P.

  P 'can be formed from galvanized sheet steel.

  The advantages of the invention result directly from

  the description which has just been made.

  The mutual interlocking function of the P. P 'plates allowing to rest the relative movement of these plates in the direction dl is ensured by the folds 3, 3' and by the edges 5, 5 ', c in fact by

parts of ranges a3, a3 '.

  It is therefore no longer necessary, contrary to what was the case in the state of the prior art, to provide that each plate has wings of complementary shapes making it possible to obtain said restrictive interlocking. Thanks to the absence of such a constraint, provision can in particular be made for each plate P. P 'to have a single wing al, capable of supporting profiles of

counter cladding (not shown).

  P. P ′ trays are thus obtained having a strong asymmetry defining a very open volume which is particularly conducive to very compact stacking: it suffices in fact to refer to FIGS. 6 and 9 to clearly see that the stacking of 2n trays has a height significantly less than n times the height of one

of these trays.

  It will be noted that, in a particularly advantageous manner, this stacking makes it possible to dispense with the need to place the trays in pairs in opposition for the purpose of their storage or their transport, and therefore to eliminate dangerous and costly manipulations both

  at the end of the production chain than on site.

  The second embodiment will be particularly preferred, on the one hand because it allows a less bulky and more stable stacking than the first embodiment, and on the other hand because it allows, thanks to the inclination of the fold 3 'and the presence of the rib 11', to obtain a restriction of the relative movements of adjacent plates in the direction d2, in addition to the

  restriction in the direction dl (see figures 7 and 8).

  The plates P. P 'which have just been described can be used to form the cladding of a wall

  "double skin" for wall or roof.

  In this case, according to a first variant, counter-cladding profiles (not shown) are fixed on the lips L, L 'of the wings al, a' of the plates P. P ', so that the joining lines of the counter -cladding are substantially perpendicular to the lines of

siding join.

  According to a second variant, counter sections

  cladding are fixed to the lips of the wings of the cladding plates by means of spacers so that the joining lines of the counter cladding are

  substantially parallel to the seam joining lines.

  It will be noted that the doubling of the lips of the cladding plates (see FIGS. 4 and 7) makes it possible to make the attachment of the counter cladding to the cladding particularly solid, and that it makes it possible to comply with the European standards in force according to which the thickness material in which the counter cladding is fixed must be

equal to at least 1.5 mm.

  When this doubling extends at the foot p, p 'of the wing al, al' (see Figures 4 and 7), a wall is obtained

  particularly rigid "double skin".

  When this doubling extends to a part of the range a3 ′ (see FIG. 7), the fixing of the cladding to support means such as posts (not shown) can be made particularly solid, by means of

example of 13 'screw (see figure 8).

  Of course, as is known per se, it is possible to place a layer of insulating material inside the cladding, or else to interpose a layer of insulating material.

  between the cladding and the counter cladding.

  Of course, the present invention is not limited to the embodiments described and shown, supplied to

  title of illustrative and nonlimiting examples.

  Thus, for example, it could be envisaged that the range of the profile according to the invention comprises transverse reinforcements, that is to say extending in a direction substantially perpendicular to that of the wing.

of this profile.

  Such reinforcements could for example be made

by embossing the profile.
