Carrier construction for building, has center part elements welded with each another such that centre part elements define sequence of apertures in centre part between side parts, where side parts are arranged vertical to center part

摘要

The construction has rafters for carrying a saddle roof of a building, and an I-shaped carrier (1) constructed from a part of the rafters and comprising a center part (2) and two parallel side parts (3, 4). The side parts are arranged vertical to the center part, where a scalloped slot (5) is formed in the center part at a predefined distance relative to the side parts. Two complementary center part elements are welded with each another such that the centre part elements define a sequence of apertures in the centre part between the two side parts. An independent claim is also included for a method for manufacturing a rafter.
