Welcome to Qingdao Steel Building Co., Ltd.
Steel structure is the most economical, durable and widely used building material. Because of the excellent performance of steel, steel structure workshop has the advantages of large span and light weight.
The design of steel structure plant adopts high-strength steel, which can withstand the impact of external bad weather and ensure the safety of indoor personnel and equipment.
It is divided into embedded bolt connection and insert type cup mouth connection. The common connection mode of ordinary steel structure workshop is mainly embedded bolt connection. Including hinge connection and rigid connection.
Embedded bolts are usually "L" shaped and made of steel rods. Diameter and length shall be determined according to design requirements. Usually φ24~φ64mm. The tightening force of a single bolt can reach 300KN.
Columns and roof beams of steel structure factory buildings are usually made of section steel and H-section steel made of steel plate. Posts and beams welded with steel plates need to be corrected after assembly and welding to prevent deformation of H-beams due to welding deformation. Steel columns and beams, usually welded or bolted, are the main load-bearing structure of the workshop.
Roof and wall panels are divided into two types: corrugated veneer and sandwich board. Monochrome panels are commonly used in buildings that have no insulation requirements and rely on purlins or wall beams to form roof and wall enclosures.
Sandwich board is mainly used in buildings requiring thermal insulation. The core materials of sandwich board mainly include polystyrene, polyurethane foam, rock wool, glass wool and so on.
