The invention relates to a supporting element for the construction of walls containing building panels and the like. The invention also relates to a method of manufacture of such a support element.The supporting elements of this type are described in the "So-vaggkatalogen" ("Catalogue of ceilings and walls"), published in 1994, "Lindab AB", which depicts the installation of so-called "is selected beams, interacting (pages 108-109). Additional examples of supporting elements in the field to which the invention relates, shows, for example, on page 113 and 119 above directory. The term "supporting element" is used hereinafter as a General concept for racks, partitions and beams etc. for the construction of walls, especially walls, in which construction the panels are mounted on the support elements.In addition, in published patent application Sweden SE-B-457,223 (corresponding US-A-4,513,551) described supporting element is U-shaped cross-section, containing wall and two side shelves for support of building panels or the like. To facilitate tightening of the bolts in the installation of building panels on the supporting elements (cf Directory, Lindab, page 105), side shelves have areas of so-called expanded metal, which are guides for the mounting bolts (see Fig. 1 in SE-B-457,223).Such supporting elements, as described above, are made from flat blanks of sheet metal, which in a special molding process is shaped U-shaped section. When this molding in the reference element is often undesirable internal stress, which can provide the data in SE-B-457,223 the presence shelves expanded metal can create a special voltage, which in the worst case will lead to the fact that the free longitudinal edges of the shelves can be bent or take a wavy shape. This wave form may occur even when two sites expanded metal formed on a flat blank of sheet metal, the longitudinal edges of which in unfavorable cases take a wavy shape with such a large amplitude (about 40 mm) that the handling of the blank of sheet metal having the form of a strip, as well as forming it into the desired supporting element, is difficult.Thus, a new reference element, which is less tends to bend and do not take the above-mentioned undesirable wavy shape.Another common requirement, which is well known, consists in that the supporting element must have sufficient rigidity to withstand linear load, perpendicular to the shelves, which arise during installation, and also when finished walls are subjected to loads. To strengthen the supporting elements have been proposed various means, the examples shown on page 113 catalog Lindab, mentioned in the introduction, and in which the wall of the support columns is time require stronger support elements, that was the starting point for the present invention. A new type of the support element, which has improved strength and rigidity and in which the shelves, in particular, hardened so that they have much less distortion in direction to each other under load, for example, in the installation of construction panels.As an additional example of the prior art may be mentioned the support element according to US-A-4,619,098 that in order to reduce heat and goodproduct made with slits. However, this patent did not mention the undesirable internal stress and lack of rigidity.Summary of the invention
The present invention is to solve the above problems (a basic element of high strength and stiffness and, consequently, the creation of an improved support element.These and other objectives, which will be clear from the following description of the invention are accomplished by an elongated support element having a cross section that contains the wall and two side shelves for support of building panels, wall has an elongated zone virani the same and which includes a series of deformations, taking place entirely or partially through the thickness of the material, such as cuts, cracks, patches notch.Preferably, the rows of deformations are located in at least two elongated parallel sections that are narrow compared with the width of the wall and which is parallel to the side shelves.Each of the rows of deformations may contain a large number of closed cuts, spaced rows.It is advisable that between the long, narrow plots was located unprocessed, without cuts material of the wall.The support element may have a U-shaped cross-section and alignment stresses placed symmetrically with respect to a Central plane extending through the supporting element is perpendicular to the wall.Area equalization voltage reference element can contain many narrow sections of the aforementioned type, arranged in pairs and equidistant from the said Central plane.Side shelf support element is made mainly from expanded metal.It is advisable to produce supporting element is made of thin sheet metal.With the ment, having a cross section that includes a wall and two side shelves to support the construction of the panels, is that the surface is flat blanks of sheet metal, which is intended for the formation of this wall, perform zone alignment stresses through what cause the rows of deformations taking place entirely or partially through the thickness of the material, such as cuts, cracks, plots with notches.Preferably, the rows of deformations is performed in the form of relatively narrow width of the wall of elongated parallel sections, which are placed in parallel side shelves and which form the means of a large number of closed incisions arranged in rows and passing completely or partially through the thickness of the material of the wall.In one embodiment, the implementation of the workpiece of sheet metal formed to obtain a cross-sectional U-shape.In another embodiment, the method uses side shelves with lots of expanded metal.Supporting element according to the invention is equipped with a zone equalization of stresses in the wall with rows of deformations, which creates greater rigidity and ability to withstand load, Italy were achieved for designs, in which area of the equalization voltage is made in the form of two elongated sections, narrow relative to the width of the wall and parallel side shelves, each of which consists of a number of closed incisions arranged in rows and extending completely or partially through the material of the wall, and these narrow areas limit the raw material without cuts.A comparative experiment with such a support element is analyzed briefly below.Supporting element length 2400 mm from thin sheet metal in accordance with the above construction, in which the shelf support element have a site expanded metal, had a support at its ends and was subjected to a linear load of 500 N/m Corresponding reference element according to the prior art, essentially in accordance with Fig. 2 in SE-B-457,223 also have shelves of expanded metal, but completely raw wall, was subjected to the same load. The deflection at the center of the support element according to the invention was only half compared with the deflection of the support element according to the prior art (about 5 mm compared to about 10 mm).In accordance with izopet the supporting element according to the prior art. Preliminary undesirable internal stresses in the bearing element are eliminated or changed due to the presence of a zone of equalization of stresses in the wall of the support element.The invention and its many advantages will be described in more detail below with reference to the accompanying schematic drawings, showing the preferred design.Fig. 1 depicts a perspective view of the flat blank of sheet metal;
Fig. 2 is a perspective view of the support element in accordance with the invention, made from blanks of sheet metal, shown in Fig. 1;

Fig. 4 is a view similar to Fig. 3, an alternative design of the wall of the support element.Description of the preferred designs
In Fig. 1, the blank of thin sheet metal generally designated as 1, and it is known by the image contains two sites of expanded metal 2, 3, which are separated by a gap from the two longitudinal edges of the blanks from the sheet metal 1. Between sites expanded metal 2, 3 blank from the metal sheet 1 has an area of alignment and consists of two longitudinal plot 5, 6, each of which consists of a large number of closed incisions arranged in rows and extending partially or completely through the workpiece of sheet metal 1, as will be described in more detail below. Between the two parts 5, 6 is Playground 7 raw material without cuts.The blank of sheet metal, shown in Fig. 1, in a known manner is formed in the support element 8 in accordance with the invention, which is shown in Fig. 2. Elongated supporting element 8 is made with a U-shaped cross-section, containing the wall 9 and two side shelves 10, 11 to support the construction of panels or the like (not shown). The site expanded metal 2, 3 side shelves 10, 11 facilitate the screwing of the fixing elements such as bolts or the like, for mounting building panels. In some cases, construction panels can be attached by gluing (not shown). It should be noted here that the invention is also applicable to supporting elements without such platforms expanded metal shelves.Area equalization voltage 4 is preferably symmetrically to the Central plane M extending through supporting esena in the wall 9. In accordance with the preferred construction area equalization voltage 4 contains two elongated section 5, 6, which are narrow compared with the width of the wall 9, the parallel side shelves 10, 11 and each of which contains a large number of closed incisions 12 arranged in rows and extending completely or partially through the material of wall 9 (see Fig. 3). As mentioned above, narrow sections 5, 6 restrict the space 7 of the raw material of wall 9 without cuts.It must be emphasized that the cuts 12, shown in Fig. 3, can be of different forms and can contain other types of deformation or distortion of the material, such as areas with cuts, cracks, etc. or combinations thereof. An alternative embodiment is shown in Fig. 4, in which the incisions are T-shaped slit 13, located in rows, and they are slightly displaced relative to each other. You need to take into account that there are several other types of dents or distortion; it is only important that the wall 9 of the support element 8 was provided by zone leveling voltages having rows of deformations, providing increased strength and reducing the risk of bending of the support element and Vozniknovenie to extend along the entire distance from one outer end 8A of the support element to the other end 8b. As a variant (not shown) these plots 5, 6 may extend either along the length of the wall 9, or at intervals.In accordance with the design of the invention, which is not shown in more detail, the area of the alignment voltage 4 contains several narrow sections 5, 6 of the above-mentioned type, arranged in pairs, preferably equidistant from the said Central plane M of the Number of narrow plots with notches is not critical to the present invention, if the wall has a corresponding area of the equalization voltage.In the method of manufacturing in accordance with the design of the invention from a flat blank of sheet metal 1 of the support element 8 in accordance with Fig. 2 provides the flat blank of sheet metal 1 zone alignment stresses 4 in the form of several longitudinal sections 5, 6, which are narrow compared with the width of the wall 9 and which are parallel and separated by intervals from one another. In addition, they are formed by cutting a large number of closed incisions 12 or 13, arranged in rows and passing completely or partially through the thickness of the material of the wall of the expanded metal 2, 3.We should mention another advantage of the support element according to the invention. In experiments in practice it was found that the alignment of stresses in the wall has a beneficial effect on the sound-absorbing ability of the support element. This side effect has been so favorable that the supporting element provided in accordance with the invention, it is possible to say that it forms a combination of the support rack and the rack, which in the language of technology is called "sound-hour".The concept of the invention is in no way limited to the design and variants described above, but many modifications are possible in the range of the inventive concept, as it is expressed in the attached claims. Especially necessary to emphasize that the invention can be used in several types of supporting elements, as stated in the introduction. The cross-sectional shape of the support element is not critical to the invention, it may be U-, C - or Z-shaped, etc. in Addition, the area equalization of stresses in the wall of the support element may be within the invention are made differently than described above. 2.
