Modern design prefab light steel structure gym

The installation order of modern design prefabricated light steel structure gym steel structure shall be carried out on the steel structure platform according to the installation order and processing technology regulations. The prefabricated components and assembly of steel components shall be carried out on the steel structure platform, and the quality shall be welded by electric welding. The spacing between the splice joint of the flange plate of the channel steel and the splice joint of the beam end should exceed 200mm. The length of the flange plate splicing should not be less than twice the plate width; The total width of beam end splicing shall not be less than 300mm, and the length shall not be less than 600mm.

In order to ensure the convenience and quality of electric welding, it is necessary to perform verification welding on the steel structure platform of the road surface according to the construction drawing specifications, including the reinforcement plates, connecting plates, cushion blocks, and cantilever beams on the upright pole and load-bearing beam as much as possible. Steel components prefabricated on steel structure platforms should not only be assembled according to construction drawings and standards, but also take into account the on-site installation process performance and changes in installation specifications.

Welding engineering is an important link in the production and installation of steel structures. Quality control of welding engineering should be emphasized. Currently, most steel structures use automatic submerged arc welding machines in the production process, some are equipped with semi-automatic gas shielded welding machines, and some parts are welded manually.
