METAL PANEL CONSISTING OF A MULTITUDE OF STRETCHED METAL PROFILES FIXED ON CROSSBARS.

FR 3 064 041 - A1 tup Metal panel made up of a multitude of drawn metal profiles (1) fixed on crosspieces (2).

The invention relates to:

- The choice of drawn metal as a material to form the profiles,

- Implementation in various forms in plan or in relief, with rectilinear or curved profiles and regular or variable sequences.

The metal panels according to the invention are particularly intended to meet the needs in the field of architecture, decoration, lighting, acoustics, infrastructure, urban planning and green spaces.

i

The present invention relates to the design of a metal panel composed of a multitude of sections of drawn metal (expanded metal), arranged generally in the same direction, and fixed on cross members oriented perpendicularly, together forming a screened web.

The use of drawn metal profiles, relatively more flexible than solid sheet profiles, extends the possibilities of realization to allow implementing curved geometries in two and three dimensions.

We will designate the invention by the generic name: stretched metal tablecloth.

To date, this type of panel exists under the designation of metallic mesh but the existing technique only implements solid sheet sections, even micro-perforated with low percentage of vacuum. The panels hitherto produced are planar.

The invention consists in placing on the field and in parallel a certain number of sheet metal crosspieces provided with notches, then bringing therein drawn metal sections, by placing them one after the other, perpendicular to the crosspieces, according to a sequence chosen and organized by the notches, before assembling them by welding or by another mechanical means allowing disassembly.

The invention makes it possible to increase the percentage of vacuum of such a structure to improve the passage of air, light, sound or a liquid.

The profiles can be arranged in different configurations so as to obtain flat or raised plies, with regular or variously organized spacings, depending on the objective sought.

The interests of this invention lie in:

1) The use of drawn metal (expanded metal) which offers many advantages:

- The range of possibilities in terms of type and size of mesh makes it possible to meet a multitude of requirements,

- This product is both rigid and malleable,

- This product is produced without waste and remains fully recyclable.

2) The creation of a mechanically resistant structure while preserving a high percentage of vacuum.

3) The possibility of proposing a modular and customizable concept by the choice of drawn metal (expanded metal), of the section of the profiles, of the regular or variable sequence, of a configuration in 2D or in 3D.

4) The ability to produce very large panels up to 10 meters in length in one piece.

The accompanying drawings illustrate the invention:

Figure 1 and Figure 2 illustrate the drawn metal profile and the possible sections.

Figure 3 illustrates the stretched metal sheet formed.

Figure 4 illustrates the principle of the crosshead.

Figures 5, 6, 7, 8 and 9 illustrate the different applicable forms.

This invention allows the production of various openwork structures applicable in multiple fields:

- Construction: cladding of facades, railings, false ceilings, wall cladding or partitions, shutters, fences, gates, technical enclosures.

- Industry: light fittings.

- Infrastructures: anti-blast barriers, acoustic panels.

- Facilities: urban furniture, green walls.

These stretched metal sheets are available in steel, aluminum, copper, zinc and alloys depending on the application.

Detailed description of the figures:

Figure 1 shows a stretched metal profile (expanded metal) - type U, strip of stretched metal folded to obtain a U-section profile.

Figure 2 shows other possible profile sections, section L, section J, section 5 omega.

FIGS. 3 and 4 respectively show the sheet of drawn metal and the cross-piece made of cut sheet metal, where appear: drawn metal sections 1, cross-pieces 2, connection points 3, and notches 4.

The drawn metal profiles are positioned by embedding their edges in the notches 10 cut in the crosspieces. The whole is joined by welding or other permanent or removable mechanical assembly method.

FIG. 5 shows a regular sequence flat sheet, with: a: width of the profile = constant, b: spacing between profiles = constant.

Figure 6 shows a barcode type flat sequence tablecloth, with:

x, y, z, u, ....: profile width = variable, b: spacing between profiles = constant.

FIG. 7 shows a flat sheet with curved profiles, in front view and in side view.

FIG. 8 shows a three-dimensional tablecloth (relief), with regular relief in front view and in side view, and with variable relief.

Figure 9 shows a 3-dimensional tablecloth (relief) randomly, in front view and in side view.
