摘要

The building section consists of a continuous metal piece with a straight middle piece (1) on each side of which is a small arm (2) with bent in edge, forming a groove for hooking the section. On the ends of the middle piece (1) are two large parallel arms (3) also with bent in edges (4). Outside the small arms (2) inside the large arms (3) and on the same side as the large arms (3) are parallel arms (5) with curved in edges forming a rectangular inner space. The arms (5) and that part of the middle piece (1) facing them have preferably small pointed ridges (7) on. A long piece of wood (8) is inserted into the rectangular space and locked by fixtures (9) going through the middle piece (1) and into the wood (8).
