Due to the complex and changeable natural conditions at the construction site, there are a series of uncontrollable and unpredictable risk factors in open-air processing, so it is often necessary to build a temporary steel bar factory for indoor processing of raw materials.

[0003] Most of the existing steel bar factories use steel pipes welded to form the column and beam skeletons of the lantern frame. Their processing and production are relatively complex, and they use a fully welded form, resulting in a high cost. A steel bar factory is used for an average of about 3 to 4 years in one project. Traditional steel bar factories do not have the function of recycling and reusing the main materials, and their assemblability, turnover rate, and repeated utilization rate are low. Summary of the Utility Model

[0006] Furthermore, the length of the column adjustable section (2) can be adjusted between 0 m and 6 m to meet the requirements of different clear heights of the steel bar factory building; the length of the beam adjustable section (4) can also be adjusted between 0.5 m and 3 m to meet the requirements of different spans of the steel bar factory building; The column standard section (1) in the portal steel frame (14) of the factory building is fixedly connected to the ground-embedded foundation anchor bolts through a flange connecting plate.

[0008] Furthermore, the standard cross-section segment of the crossbeam (3) is composed of variable-section welded H-shaped steel, which can reduce the amount of steel used while meeting the strength and stiffness requirements. The adjustable segment of the crossbeam (4) is composed of variable-section H-shaped steel.

Compared with the two types of purlins, the use of galvanized square tubes can meet the requirements of turnover and reuse, while the C-shaped steel will be deformed and distorted due to its cross-sectional properties during disassembly and transportation. Repeated use requires straightening treatment, which increases the straightening cost, and in severe cases, the purlin will be scrapped. The galvanized square tube has the advantages of being free of painting, easy to install and disassemble, not easily distorted and deformed, and having a high degree of turnover use;
