Light Frame Pre-Engineered Steel Warehouse Steel Factory Buildings

Prefabricated steel structure factory building mainly refers to, the main load-bearing components are composed of steel, processed in advance.Including steel columns, steel beams, steel structure foundation, steel roof truss (of course, the span of the workshop is relatively large, basically all steel structure roof truss), steel roof, pay attention to the wall of steel structure can also be maintained by brick wall.

First, steel structure installation procedures

Installation of steel column → installation of support between columns → temporary position of steel crane beam → roof beam and roof support → correction and fixation of steel crane beam, etc. → installation of maintenance structure

Second, steel column installation

(1) Due to the large weight and length of the steel column, it is impossible to make and transport the steel column at one time. Therefore, the method of segmented production and on-site assembly is adopted to make the steel column as a whole and then hoisting is carried out. It is proposed to make the steel column in two sections.The steel column is divided into two sections, the lower lattice section and the upper H-beam section, which are transported to the site.The weight of the steel column is about 6 tons, and the position height is about 17 meters. The truck crane of 50 tons can meet the lifting demand, and then a truck crane of 25 tons can be used for lifting.

(2) Lifting using single machine rotary lifting.Before lifting, wood should be padded at the position of the steel column foot plate, so as not to damage the column foot plate in the process of lifting.When the steel column is hoisted, the crane should hook up and turn the arm at the same time to make the steel column vertical off the ground and put the column into the mouth of the cup.
