Embodiment Construction

[0032] The mechanically welded structure shown in FIG. 1 has a first planar thin metal structural element 10 extending in a plane P, delimited on one side by a straight edge 15, the mechanically welded structure also has a welded connection to the straight edge 15. Second metallic structural element 20 on intermediate element 25 of edge 15 .

[0033] The intermediate element 25 is interposed between the first and second structural elements 10 and 20, the second structural element 20 exerting a force F at at least one point 151 of the straight edge 15, which resolves into at least one force F perpendicular to the straight edge 15. Components extending in plane P.

[0034] In FIG. 1, the intermediate element 25 is a flat metal plate, the first structural element 10 is a rib welded to the first surface 251 of the plate 25, and the second structural element 20 is welded to the first surface 251 of the plate. Another rib on the opposite second surface 252.

Abstract

The mechanically welded structure has a first flat thin metallic structure element (10) extending in a plane and having one side demarcated by a rectilinear edge (15); and a second metal structure element (20) welded to the rectilinear edge of the first metal structure element (10) or an intermediate element (25) coupled to the rectilinear edge (15). The intermediate element is inserted between the first metallic structure element (10) and the second metallic structure element (20) which applies a force, resolving into at least one ingredient extending in the plane vertically to the rectilinear edge (15), on at least one point (151) of the rectilinear edge (15). This invention provides the first structure element (10) with a stress relaxation slit (12) extending in parallel to the rectilinear edge (15) and positioned opposite to a point on which the force is applied.

Description

technical field [0001] This invention relates to the metal construction industry. [0002] More precisely, according to a first aspect, the invention relates to a mechanically welded structure having a first planar thin metallic structural element extending in a plane and delimited by a straight edge on one side, and a second metallic structure element, the second metallic structural element being welded to the straight edge of the first structural element, or to an intermediate element connected to said straight edge and interposed between the first and second structural element, the second structural element being At least one point of said straight edge exerts a force that resolves into at least one component extending in said plane perpendicular to said straight edge. Background technique [0003] Structures of this type are well known in the art and are used in a wide variety of metal structures. [0004] They are used in particular in the construction of liquefied ga...
