WALL BEAM SECTION

Abstract: A wall beam section consisting of two parallel, mutually spaced wall panel (1) attachment sections (2) interconnected with a connecting member (3). Since in designs known through prior art the member connecting the attachment sections (2) is formed of the same metal sheet as the attachment sections themselves, the wall beam section is sound-transmitting and disadvantageous as regards fire safety. In the invention, the member connecting the attachment sections (2) consists of a plurality of supporting sections (3) affixed to the margins (4) of the attachment sections (2) with a given spacing.

Description: Wall beam section The present invention concerns a wall beam section consisting o-f two parallel, mutually spaced wall panel attaching sections inter¬ connected by a connecting member. In wall beam sections of prior art* the member connecting the attachment sections is a metal plate Integral with the attachment sections, constituting the bottom element in the U shape o-f the wall beam section. The drawback encumbering previously known wall beam sections o-f this kind is that they conduct sound through the wall, and regarding -fire safety it has to be noted that they con¬ duct heat through the wall. Endeavours have also been made to manu facture the wall beam section of the thinnest possible sheet mater iall this again gives rise to the drawback that the attachment section bends inward when the wall panel fixing screws are drilled into the attachment sections. If a partition fitted with wall beam sections of prior art is large in size and the differential temper ature between the two sides αf the wall is remarkable, the attach¬ ment sections of the wall beam sections undergo different expan¬ sion, causing the entire wall to curve. The object of the present invention is to eliminate the drawbacks mentioned. The wall beam section of the invention is characterized i n that the member connecting the attachment sections consists of plurality of supporting sections affixed tα the margins αf the attachment sections with a given spacing. By the aid of the inven¬ tion considerably superior sound insulation is achieved, as well a a partition presenting higher fire safety. The wall beam section will not bend even if the differential temperature of the attach¬ ment sections should vary considerably. An advantageous embodiment of the invention is characterized in that the point where the supporting section is affixed to the attachment section is insulated with plastic for instance. There¬ fore, quite remarkable sound insulation of partitions is attained because there is no metallic part tα conduct sound from one attach¬ ment section to the other. Another embodiment of the invention is characterized in that both margins of the attachment sections are interconnected with support¬ ing sections. Hereby a kind of box-type structure with excellent rigidity is obtained. A third embodiment of the invention is characterized in that the supporting section is affixed to the attachment section with a punched-through deformation juncture. Xn this way a method for fixing the supporting section and the attachment section to each other is obtained which is very fast and favourable, and easy to automate in the manufacturing process. An advantageous embodiment of the invention is furthermore charac¬ terized in that the supporting section is an L-shaped section strip, the ends of its horizontal flange part resting against the inner surface αf the attachment sections. It is hereby achieved that the attachment sections are braced against forces acting from the outside in connection with drilling hales far the fixing screws. The invention is described in the following with the aid of an example, referring to the drawings attached, wherein Fig. 1 presents a wail beam section according to the invention, viewed obliquely from above. Fig. 2 presents a conventional wall beam section, in a partition, in top view. Fig. 3 presents, in a partition, a wall beam section according to the invention, viewed from one end. Fig. 4 presents the wall beam section according to another embodi¬ ment of the invention. Figs 5-7 present various types of fixing between the supporting section and the attachment section. The wall beam section consists αf two parallel, mutually spaced attachment sections 2 for wall panels 1, said attachment sections being interconnected with a connecting member 3. The member 3 cort- necting the attachment sections 2 consists of a plurality αf sup¬ porting sections 3 affixed with a given spacing to the margins 4 α the attachment sections 2. The point where the supporting section is affixed to the attachment section 2 is insulated, for instance with a plastic coating on the supporting section. The rivets 5 by which the sections 2,3 have been interconnected are also coated with insulating plastic. In Fig. 4, both margins of the attachment sections 2 have been Interconnected with supporting sections 3, whereby a box-like structure with excellent rigidity is obtained. In Figs 1, 3, 4 and 5, the supporting section 3 is an L-shaped section strip 3, the ends of its horizontal flange part resting against the inner surface of the attachment sections 2. In Fig. 7, the supporting section 3 has been affixed to the attachment sectio 2 with a punched-through deformation juncture. The partition structure gives substantially better sound insulatio than any wall beam sections of prior art because there is no sound conducting metal between the attachment sections 2. A partition built using the wall beam sections also affords considerably highe ire safety because the heat generated in the event of fire is not at once transmitted from one attachment section 2 to the other attachment section 2. The wall beam section also retains its straight shape. There is a differential temperature of a remarkabl height between both sides of the wall. The L-shaped section strip braces the attachment sections against the screw-tightening and drilling forces F required in fixing the fixing screws 6 of the partition panels 1. It is obvious to a person skilled in the art that the invention ma vary within the scope of the claims following below.
