The present invention relates to process for the friction between collection and fixation of successively arranged, prefabricated plate elements, essentially floor-high, edge of the profiled wall or facade panels, by means of the profile, formed by the edge stamping or roll forming, slightly springs existing quality of steel, and wherein the spring effect is applied to the to ensure density in the joint between two adjacent panel set.

The method according to the invention, thereby establishing lightweight partition walls consisting of storey-high wall panels with profiled vertical edges and of the specially shaped profile, preferably a thin plate sections of steel, and wherein the wall panels will typically be pre-fabricated on the fixed width, and with a profiled vertical edges throughout their extent, the one vertical edge of wall panels is formed with groove and the other vertical edge is formed with both the tongue and groove. The steel profile which thus functions so a kind of stud in the wall structure is dimensioned to ensure the desired wall thickness, and in addition to its profile parts with each other to fix, join, stabilize and lock the four panel edges which meet in pairs, mutual engagement, where two panels are assembled end to end in a wall surface.

The combination with the specially shaped steel profile, and in particular corrugated sheet edges for co- action therewith, is known from many other constructions. Examples include U.S. Patent No. 3 49 529 and Danish patent No. 143459, as for the latter patents, are also designed to provide a solution for creating partition walls, without the occurring friction, as the wall panels is inserted into engagement and end to end in a wall surface.

The special and characteristic is obtained according to the invention consists in that the panels are inserted in the construct without the friction during the joining, and in that close and firm assembling with each other between the panels thus obtained by a rotary process, in which the panel pair of which is during mounting, it will affect pre-mounted pane! par to activate the springs existing capacity of the steel profile, which then represents the force which finally ensures a firm and compact assembly of the four panel where the edges meet, a two-panel pairs assembled end to end over a steel section. To yield the steel springs properties in the manner of the simultaneous and moreover, the two mutually facing panel edges are not independent of each other can be pressed into the structure after the installation, which would be the case if the steel springs properties had been applied to the inside, and the clamping into the cavity at the opposite rear sides of a panel pairs

For example, one could imagine, with reference to Patent No. 143459, the plate body (5) was designed as a steel profile, which springs backhoe could range from the rear of the panels (7), to thereby create a spring existing pressure against the back of the groove end panel portion (1 ). In such a situation would be exactly the springs backhoe undesirably allow the panels (6-7) able to be moved independently of each other inwardly of the structure, increasing the possibility of formation of cracks, if the wall next to be filled, or papered. The effect of using plate elements via a barbell function to draw an assembly profile of the springs absorbing material as a sheet metal into its final shape and simultaneously to apply the same steel section to ensure the mutual distance between the plate elements, is known from

French Patent No. 270317. The invention of this specification assumes that there is only along one of the panel pair of edges, that the lever function can be exploited for which reason a subsequent panel pairs will not be included as weight rods for the steel profile, which must be brought into engagement with the edge zone of a preceding panel pairs. Lever function according to the French patent relates not to use steel profile springs sparkling effect to ensure each set of consecutive panel pair, and, according to his principle could not be drawn to it.

Thus steel profiles form in conjunction with the principle of the panel's edge profiling, which together form the system which creates the opportunities of the present invention. The key is steel profile that is substantially shaped as a U-profile, Z-shaped lugs that are so long relative to the thickness that the forces that transformed the structure of the actual inter panel jointing, used to pulling the U-section Z- shaped tabs from one another such that the steel spring effect will ensure firm fastening of the panels with each other.

The method according to the invention will now be further explained with reference to Figures 1 and 2 of the accompanying drawings, in which the of the figure 1 seen in a horizontal nits, how the interaction between the metal profiles, the panel edge the groove and the panel edge to both the groove and groove co-operates, and with each other and mutually locked and to stabilize each other.

Figure 2 shows how the steel gauge principle is formalized.

The system and method of the invention is explained in more detail with reference to the accompanying drawings.

Of the horizontal nits in Figure 1 shows how the panels (1 ) is joined to the panels (2) over steel profile (3). The edge detail is shown for the panels (1 ) indicates how the identical panels along one edge is shaped with tongue and groove end fold, and the edge of the detail of the panels (2) shows how the panels along the opposite parallel edge is profiled with a groove in which the rebate portion down bear against the back of the folding of the end edge (8) of the panels (1 ). It is apparent from Figure 1 that the steel profile (3) is inserted in the notes of the panel pair (1 ), and that the panel pair (2) is inserted in the construct in such a way that their bending portion (7) abuts against the back of the fold edge (8) of panel pairs (1 ), and the panel pair (2) with their backs resting against the corners) of the steel section (3).

When the steel profile (3) of Figure 2 is dimensioned such that the angles (10) is made slightly smaller than they would be when the profile has assumed its final function of the structure, and consequently the distance between the profile parts (9), and also be less than the distance will be between the same profile parts when the steel profile has assumed its final function after installation. It is this relationship that creates the desired spring effect. The function and interaction of structural components, thus occurs during the actual installation where an extension of an already established panel pair (1 ) then continue with the next panel pair (2).

The first thing that will happen is that the steel section (3) introduced into the groove (4). Panel couple (1 ) will then because of the steel profile undersize between the flaps, be pulled slightly closer together than their final mutual distance. When the bar pair (2) then rotated into its engagement in the construct, as indicated by the dashed lines and arrows, it will make contact with the back of the folding portion (8) of the panel pair (1 ) and with a steel profile corner (5) before the panel pair (2) is completely at his place in the wall surface. Panel two (2) will straddle a little. When the panel pair (2) pressed finalized the pressure on the groove portions (6) as a result of the panel's position against profile corners (5) enforcing the steel profile tabs are pulled apart so that the angles (10 Figure 2) is opened slightly. This gives the desired spring effect which ensures the solid fixing of all the structural components interacting with each other.

Figure 2 also shows that the angle (10) is significantly less than 90 degrees. The intention is to create the necessary space for the corner (1 1 ) on panel pair (2) as is necessary, it is possible to introduce the panels diagonally from the outside without resulting friction and resistance. The utilization of the power spring in this manner implies that the angle (10) is always less than 90 degrees.
