Description

Technical Field

[0002] During the construction of single-layer steel structure installation projects, the columns and inter-column supports are generally hoisted by the single-piece flow method. The columns can be installed and corrected at one time before the inter-column supports and other components are installed. When using a truck crane, considering the inconvenience of movement, 2 to 3 axes can be used as a unit for operation. The roof system hoisting usually adopts the "inter-section comprehensive method", that is, one section is completely installed to form a stable unit, and then other units are installed based on this. The number of single-layer steel structures used in venue buildings is increasing. In order to ensure production safety and avoid safety accidents due to non-compliant external frame erection during construction, double-row ground-mounted steel pipe scaffolding is the most convenient and economical scaffolding solution for facade decoration.

[0003] However, in order to ensure the safe use of scaffolding during construction, the setting of external frame wall parts is indispensable. The amount of steel pipes and fasteners is large, the manual operation workload is large and the efficiency is low, which invisibly increases the cost of scaffolding. Traditional steel pipes and steel structure buildings currently do not have a special connection structure, and welding will also cause damage to steel components, which is not allowed during construction. Therefore, the connection between traditional steel pipes and steel components is a technical problem that needs to be solved, and it is particularly important to design a connection structure other than welding.
