STUD DEVICE FOR WALL CONSTRUCTIONS

Abstract: A stud device for wall constructions, comprising a web (1) and at least one pair of flanges (2, 3, 4, 5) arranged at the longitudinal edges (6, 7) of the web (1) and protruding from the same side of the web (1) substantially parallelly to one another. In order to reduce the number of studs and the amount of work when erecting a right-angled corner, for instance, either facing inwardly or outwardly in the wall, the stud has an angle ( alpha ) between the web (1) and the flanges (2, 4) at one of the longitudinal web edges (6) which, in such a right-angled corner, is 45 DEG , and an angle ( beta ) between the web (1) and the flanges (3, 5) at the opposite longitudinal web edge (7) which, in such a right-angled corner, is 135 DEG .

Description: Stud Device for Wall Constructions FIELD OF THE INVENTION The present invention relates to a stud device for wall constructions, comprising a web and at least one pair of flanges arranged at the longitudinal edges of the web and protruding from the same side of the web substantially parallelly to one another. PRIOR ART In wall constructions, e.g. partition walls for buildings, the studs mentioned above are normally fastened to a bottom and top sill, whereafter an appropriate covering is mounted. Possibly, the wall construction may be provided with a wind and moisture barrier and/or a diffusion barrier and, when needed, it may also be insulated to avoid undesired thermal losses, noise influence, etc. To fasten the covering, e.g. by using screws, the stud may include one or two pairs of parallel flanges protruding from the same or a respective side of the web. As the total costs for the purchasing and mounting of the wall mentioned above are considered as being favourable, its use has been very large in several fields, e.g. the constructional field. However, prior art studs are not very appropriate for use in possible corners. The same is also the situation when an end portion of the wall shall be attached to an adjacent construction in an inclined manner, or the wall has curved configuration. Therefore, in connection with a corner two or more studs are needed to provide an appropriate support for the covering. Accordingly, such wall corners will result in increased costs for the erecting of the wall as more studs have to be purchased and the necessary amount of work increases simultaneously. Regarding the use of the prior art studs in connection with an inclined adjacent construction or a curved wall, the extra costs are mainly due to the increased amount of work. SUMMARY OF THE INVENTION The situations mentioned above concerning the prior art studs are remedied by the present invention wherein, according to the independent patent claim 1 , the angle arranged between the web and the flange(s) at one of the longitudinal edges of the web is less than 90°, and the angle arranged between the web and the flange(s) at the opposite of the longitudinal edges of the web is more than 90°. In connection with for instance a corner in the wall construction this means that the use of only one stud is needed. Further, the stud according to the present invention may be used both in an inward an outward comer by simply turning the stud 180° around its longitudinal axis. Other advantageous features according to the present invention will be apparent from the dependent patent claims and the remainder of the description. BRIEF DESCRIPTION OF THE DRAWINGS In the following part of the description a preferred embodiment of the invention will be explained, with reference to the attached drawings. Fig. 1 shows schematically in side view a longitudinal segment of a stud intended for the use in a right-angled corner of a wall construction. Fig. 2 shows schematically a horizontal section through the stud shown in Fig. 1. DESCRIPTION OF EMBODIMENTS In the shown embodiment the stud for wall constructions includes a web 1 and two pairs of flanges 2, 3, 4, 5. These are arranged substantially parallelly to one another at the longitudinal edges 6, 7 of the web 1 and extend outwardly from each side of the web 1. Further, the stud has an angle α between the web 1 and the flanges 2, 4 at one of the longitudinal web edges 6 which is less than 90°, and an angle β between the web 1 and the flanges 3, 5 at the opposite longitudinal web edge 7 which is more than 90°. The stud according to the illustrated embodiment is intended to be used in connection with a right-angled corner involving that the angle α is 45° at the longitudinal web edge 6 to the right in Fig. 1 , and the angle β is 135° at the opposite longitudinal web edge 7. Further, if during the manufacturing other appropriate sizes of these angles and β are chosen than the illustrated ones being 45° and 135°, the present stud may be used in other corners different from the right-angled, or in a wall having curved configuration. As already mentioned the present stud may also be used both in the outward and inward corners by turning the stud 180° around its longitudinal axis. If the stud according to the present invention in a not illustrated manner only is provided with one pair of flanges at the longitudinal web edges 6, 7, e.g. the two flanges 2, 3 facing to the left in Fig. 2, such a stud may be used at an end portion of the wall which is to be attached to an adjacent construction in an inclined manner. The stud having one pair of flanges 2, 3 may be used in an end portion situated at the rigth or left side of the wall by turning the stud 180° around its longitudinal axis corresponding to a stud having two pairs of flanges 2, 3, 4, 5. It will be understood that the stud according to the invention may be manufactured having dimensions adapted to any actual width of the wall construction, e.g. conventional widths of 100 mm or 150 mm. Moreover, the skilled person in the art will realize that the present stud may be used in any type of wall constructions such as load-bearing and not load-bearing outer and inner walls in buildings, partition walls on board of ships, freestanding wall constructions for instance intended for noise and screening protection or for dividing of areas, etc. There are also few, if any limitations regarding the types of covering that can be used in connection with the respective wall construction. Further, it shall be mentioned that the stud, as well as the bottom and top sills may be manufactured of any appropriate material such as aluminium, cold-rolled steel, plastic, etc., and that the stud web in the known manner may include apertures for throughrunning of tubes, cables, etc., and possibly an insulation against thermal bridges arranged in the web.

Claims: PATENT CLAIMS 1. A stud device for wall constructions, comprising a web (1) and at least one pair of flanges (2, 3, 4, 5) arranged at the longitudinal edges (6, 7) of the web (1) and protruding from the same side of the web (1) substantially parallelly to one another, wherein the angle (α) arranged between the web (1) and the flange(s) (2, 4) at one of the longitudinal edges (6) of the web (1) is less than 90°, and the angle (β) arranged between the web (1) and the flange(s) (3, 5) at the opposite longitudinal edge (7) of the web (1) is more than 90°. 2. A stud device according to claim 1 , wherein the angle (α) is 45° at one of the longitudinal web edges (6), and the angle (β) is 135° at the opposite longitudinal web edge (7). 3. A stud device according to claim 1 or 2, wherein the stud is provided with two pairs of flanges (2, 3, 4, 5) at the longitudinal web edges (6, 7), for use at a portion of the wall construction constituting a corner, or when the wall construction has a curved configuration. 4. A stud device according to claim 1 or 2, wherein the stud is provided with one single pair of flanges (2, 3) at the longitudinal web edges (6, 7), for use at an end portion of the wall construction which, in an inclined manner, shall be attached to an adjacent construction.
