摘要

The roof arches consist of at least one beam(5) which consists of two parallel sections. The roof arches are connected by their ends to the upper ends of bearing supports(1) by metal plates(10,15) fitted between the beam sections, and interconnected in the region of the apex(4). The metal plates are connected to the bearing supports especially by welding. Holes are provided in the metal plates for the fitting of screws(20) by which the beam sections are interconnected and connected to the plates.
