Abstract: Profiled roofing sheets for buildings are reinforced by supporting members (10) in an area of a roof structural support member (2) carrying the profiled sheets (1). The supporting members (10) are profiled and intended to be placed between the beam (2) and the profiled sheet (1). A supporting member is first placed on the structural support member and a profiled roofing sheet is thereafter laid on top of the supporting member after which a further supporting member is placed on the structural support member, the further supporting member connecting to the previously laid-out profiled roofing sheet and/or the previously placed supporting member in an upwardly guiding way, after which another profiled sheet is laid out on top of the further supporting member etc.

Abstract: The invention relates to a profiled sheet for building purposes, especially roofing and facade sheet, the sheet having a normal profiling and having in addition, at least in certain sections, a corrugated microprofiling deviating from the normal profiling. The microprofiling exhibits flattened and/or pressed-in areas in its crest, valley and/or flank sections resulting in that the thickness of the profiled sheet varies in a direction transversely of the longitudinal direction of the microprofiling which agrees with the longitudinal direction of the normal profiling. The flattened and/or pressed-in areas extend in the longitudinal direction of the microprofiling.

Abstract: The present invention refers to a pallet and a method for manufacturing said pallet. The pallet is made of sheet metal, preferably a one-piece sheet metal blank, said pallet comprising a load-carrying plane (2;2';2") provided with reinforcing grooves (7a,7b,8;7'a,7'b,8';7"a) and lateral pieces (3,4) provided with recesses (5) or openings (6), so arranged that the pallet is accessible from all sides for lifting means inserted beneath the load carrying plane (2;2';2").Significant for the pallet according to the invention is that almost all material in the blank is used. This is expecially brought out when the material sections moved aside, by folding, from the main planes of the lateral pieces (3,4), to create recesses (5) or openings (6), are comprised in box beams (40,41,48;40',41',48') reinforcing the pallet.

Abstract: A system for supporting a pre-shaped thin-walled external roofing (7) on a layer (4) of medium-hard insulation supported on an underlying carrying roof structure (1), which system has the form of a strip, characterized in that the strip comprises a plurality of groove-shaped portions (5a) interconnected by crest-shaped portions (5b), securing members (6) extending through the bottom of the groove-shaped portions (5a) and connected to the carrying roof structure (1). The external roofing (7) is connected to the crest-shaped portions (5b) of the system by fastening members (11).

Abstract: A roofing sheet intended to constitute external roofing, especially for roof constructions for small houses, comprises an upper edge which the mounted state of the sheet extends horizontally and perpendicular to the pitch, and is shaped to act as a beam, a lower edge which extends in parallel with the upper edge and is formed to overlap the upper beam section of an underlying sheet. The upper beam section and the lower edge are connected by groove-shaped portions, which in the mounted state of the sheet extend in the direction of the pitch.
