The principle is still the same as that of a child riding Lego. The required columns, beams and plates are produced in the factory and assembled one by one on site. According to the structural division of steel structure buildings, steel structures can be divided into frame system, frame-brace (shear wall plate) system and tube system (frame tube, tube in tube, truss tube, tube bundle, etc. ) and mega-frame system, which are different in structure.
The construction process of assembled steel structure building is as follows:
The first steel column is hoisted in place.
Bolting and fixing
Installing steel beam
Spray fire retardant coating
Install the reinforced truss floor and install the floor support system.
Laying hydropower pipeline and main reinforcement
deposit concrete
