Do you need to determine the installation sequence of steel components before installing steel structures

The main advantages of Fast Steel steel structure are: greatly save the construction time, not affected by the season; Increased the area of living space; Reduces construction waste and environmental pollution, and can reuse construction materials; It promotes the development of other new building materials industry and has good seismic performance. Easy to convert, flexible and convenient to use; Bring comfort, etc.

The installation process of high-rise steel structure is as follows:

1. Process flow chart of high-rise steel structure before installation;

2. Reasonable division of construction water section; 

3. Determine the installation sequence of steel members; 

4. When cranes are allowed to lift, structures that can be assembled on the ground should be assembled on the ground as far as possible, such as steel columns, steel supports and steel trusses that can be lifted in place at one time; 

5. Stairs and profiled steel plates shall be installed immediately after each beam of the column is installed. Stacking materials shall not exceed the bearing capacity of beams and plates; 

6. Components should be installed from the central core area (the frame of a standard room) to the surrounding area, from bottom to top;

7. The flow section, installation, correction and fixation of components (including residual welding shrinkage, after measurement), the welding sequence of the joint of general components should be symmetrically expanded from the middle of the plane to the periphery, and vertical according to the process requirements; 

8. Installation of steel structural parts and construction of steel concrete floors shall not be more than 5 storeys apart from each other. When the distance must exceed 5 storeys, it shall be checked and calculated by the responsible designer.
