Definitions

• Element comprising a bearing face intended to receive a face plate, in particular a plasterboard
• the present invention relates to an element having a bearing surface for receiving a facing plate, in particular a plasterboard.
• Facing plates may be for example plasterboard. This is actually a composite plate having a layer of plaster, or plaster base, sandwiched between two sheets of cardboard.
• the structure against which the facing plates rest is most often made using metal profiles.
• the construction of a vertical partition between a floor and a ceiling is considered here. It is then known to have at the place where it is desired to make the partition a first rail fixed to the ground, a second rail, parallel to the first rail and fixed to the ceiling, the two rails defining the vertical plane of the partition to be made .
• U-shaped or C-shaped studs are then attached between the floor-fixed rail and the ceiling-mounted rail. The interval between two amounts corresponds for example to the width of a facing plate. Facing plates are then positioned each time between two uprights and the edges of each facing plate are fixed on the uprights.
• the stiffness of the wall thus produced depends of course on the stiffness of the facing plates used and the structure, also sometimes called frame, which receives the facing plates.
• a third factor influencing the stiffness of the partition made is the way the plates are fixed to the framework.
• the standards for mounting a plasterboard wall provide for the use of screws of a given type and to make the screwing of the plate with a determined pitch between two neighboring screws. For example, self-drilling screws are provided in the edges of a plate with a pitch of 30 cm.
• the manufacturer's mounting standards are adapted to obtain the desired characteristics. It has been noticed that by increasing the tightening density the stiffness of the partition was improved. It is also known, to improve the stiffness of the partition, to come and stick the facing plate on its supporting structure.
• the disadvantage when increasing the tightening density is that the exposure time is increased.
• the bonding besides the fact that the installation conditions are more restrictive than for a simple screwing, it poses problems when disassembly of the partition is envisaged.
• the present invention therefore aims to provide means for making a wall, vertical or ceiling, whose stiffness is improved without having to increase the screw density, nor having to use a bonding.
• an element comprising a bearing face intended to receive a facing plate and being in the form of a folded sheet and / or cut and / or stamped and / or profiled.
• the bearing face has pointed bosses protruding from the bearing face, the side intended to receive the facing plate.
• bosses makes it possible to improve the connection between the element comprising the bearing face and the facing plate that it is brought to receive. As a result, it is possible to improve the stiffness of a vertical partition or a ceiling.
• the bosses are preferably regularly distributed on the bearing face.
• Plasterboard is a composite sheet in which a plaster core is sandwiched between two sheets of cardboard. It is preferable that in the mounted position of a plasterboard on the bearing face of an element according to the present invention, the pointed bosses pierce a sheet of cardboard and that the tip of the boss enters the plaster core .
• the angle at the top of the cone is preferably less than 30 °.
• the height of a boss relative to the bearing face is for example between one and three times the thickness of the sheet, for example between 1 and 5 mm.
• a boss is for example remote from a nearby boss with a distance of between 1 and 30 cm.
• An element according to the present invention may be a U-shaped or C-shaped element, having a bottom and two side walls, the bearing face corresponding to the outer face of the bottom. This is for example an element taking the general shape of a fur used to make a secondary framework false ceiling.
• An element according to the present invention may also be a U-shaped or C-shaped element, having a bottom and two side walls, each outer face of a side wall constituting a bearing face having bosses. This is for example an amount used to achieve a vertical partition frame.
• the present invention also relates to a vertical partition comprising a lower rail, an upper rail, uprights extending between the lower rail and the upper rail as well as facing plates, characterized in that at least one post is an element such as as previously described.
• the present invention also relates to a false ceiling comprising a primary frame suspended from a ceiling and a secondary frame mounted on the primary frame and having furs arranged parallel to each other as well as facing plates attached to the furs of the secondary frame, characterized in that the furs are elements as described above.
• the facing plates are for example plasterboard.
• the plasterboard comprises for example a plaster core sandwiched between two sheets of cardboard and are screwed onto an element according to the present invention.
• the majority of the pointed bosses of a support face receiving a plasterboard preferably pierce a cardboard sheet of a corresponding plasterboard to penetrate into the core of said plate.
• FIG. 1 is a perspective view of a stub section according to FIG. the present invention can be used for the realization for example of a vertical partition,
• FIG. 2 corresponds to a section along line 11-11 of FIG. 1,
• FIG. 3 is a perspective view of a fur according to the present invention that can be used for example for producing a false ceiling
• FIG. 4 illustrates the mounting of a plasterboard on an element according to the present invention
• FIG. 5 illustrates examples of bosses in elevation
• Figure 6 illustrates examples of boss base shapes.
• Figures 1 and 2 show here a profiled piece that can be used as an amount for the realization of a vertical partition. It may be for example a partition of the type known under the trademark Placostil.
• the element that is shown in Figures 1 and 2 is for example obtained from an amount marketed by Placoplatre Company under the name Stil M48.
• Figures 1 and 2 show a section of amount. This amount is obtained from a profiled piece C. It then comprises a bottom 2, two lateral flanks 4 and flanges 6.
• the bottom 2 is a flat bottom, optionally grooved longitudinally to strengthen it. As the rest of the amount, the bottom 2 is made for example of galvanized steel.
• the thickness of the sheet used here is for example 0.6 mm.
• Each lateral flank 4 extends from the bottom 2, perpendicularly to this bottom 2.
• the two lateral flanks 4 are therefore parallel and extend from the same side of the bottom 2.
• the free edge of each lateral flank 4, c that is to say the edge opposite the bottom 2 is folded at 90 ° to form the flanges 6.
• a metal section described above is already known to those skilled in the art.
• a profiled element is used as an amount. Most often, this amount then extends between a floor and a ceiling and its lower end, on the one hand, and its upper end, on the other hand, are each arranged in a profiled U-shaped rail of suitable dimensions.
• the rails and the amounts connecting them then form a framework on which plates of siding, including gypsum board, can be screwed on both sides of the frame.
• the amounts are arranged so that the side flanks 4 are oriented parallel to the wall to be made, and therefore parallel to the facing plates.
• self-drilling screws are used which, on the one hand, pass through the fixed facing plate and, on the other hand, the corresponding lateral flank 4.
• Stil M48 type registered trademark
• each lateral flank 4 has a plurality of bosses 8 forming a projection towards the outside of the upright.
• the boss 8 is obtained by deformation of the sheet forming the side flanks, or more generally the amount. These bosses 8 may for example be obtained by stamping. On the side of the side flank 4 facing the inside of the upright, there is then a depression corresponding to each boss 8.
• the bosses are pointed and thus have a generally conical shape.
• Figure 5 without claiming to be exhaustive, illustrates different possible forms of elevation points. These shapes are generally conical with variants. A first form shown is purely conical, a second is a combination of two cones of different vertex angles, a third shape is rather ogival shaped and the fourth is diamond-shaped.
• the base of the bosses can then have various shapes such as those illustrated in Figure 6, which are given by way of non-limiting examples.
• the height h of the bosses is for example of the order of 1 to 5 mm. It is thus for example about twice the thickness e of the sheet used to make the amount.
• On a lateral flank there are preferably two rows of bosses 8. Each row extends longitudinally parallel to the plane of the bottom 2. The two rows are spaced from each other by a distance of about 10 at 20 mm. Of course, this distance depends on the dimensions of the lateral flanks. In general, a lateral flank 4 receives the edges of two plates of facing. It is then expected to associate with each edge of the facing plate a row of bosses 8.
• bosses 8 are repeated preferably with a regular pitch. This step is for example of the order of 100 mm.
• Figure 3 shows another element according to the present invention. This is also a C-shaped element.
• the element of FIG. 3 is made from a fur marketed by Placoplatre under the name Stil F530 (trademark Mark). The same references are repeated here for the description of this figure as for the description of FIGS. 1 and 2.
• bosses 8 which are similar to the bosses described above, are made at the bottom 2 of the element. Indeed, it is the outer face of the bottom 2 which is intended to serve as a support surface for receiving facing plates. The bosses 8 are then made in the bottom 2 extending outwardly of the profiled element shown.
• bosses 8 are arranged in pairs in the same transverse plane on the same lateral flank 4.
• FIG. 4 An assembly of a plasterboard 10 on an element according to the present invention is illustrated in section in FIG. 4.
• the plasterboard 10 in a conventional manner, is composed of a plaster core sandwiched between two sheets of plasterboard. as usually illustrated, the gypsum board 10 bears on a support surface of a post or fur which is here an element according to the present invention with 8 pointed bosses.
• the plasterboard is held tightly on the element according to the present invention using self-drilling screws 12. In the mounting position, by tightening the screws 12, the bosses pierce the cardboard sheet of the plasterboard 10 and penetrate into the core of the plasterboard.
• bosses were made differently from the proposal made in the description above. Instead of coming to deform the sheet by stamping, one could consider making the bosses for example continuously during the profiling operation by means of stamping rolls.
• the bosses can also be obtained by cutting or can also be reported on the support surface using for example adhesive tapes. A large sandpaper type sandpaper could also take place on the support surface to form the bosses.
• the shape of the bosses may be irregular, as well as the arrangement of the bosses. It can thus have bosses of different heights.
• the bosses may be aligned or not, placed randomly or along all kinds of curved lines and / or broken.
