1) Process flow chart for steel structure installation before high-rise steel structure installation construction

2) Reasonably divide the construction flow sections;

3) Determine the installation sequence of steel components in sequence;

4) When the lifting capacity of the crane allows, structures that can be assembled on the ground should be assembled as well as possible on the ground, such as steel columns and steel supports, steel trusses, etc., which can be lifted into place at once;

5) The installation of the flow section can be divided according to the plan shape, structural form, construction period, on-site construction conditions, and number of installation machinery of the steel structure building;

6) The installation sequence of components should develop from the central core area, i.e. the standard room frame, to the surrounding areas on the plane, and be installed piece by piece from bottom to top vertically;

7) After determining the flow section, component installation, calibration, and fixing methods (including reserved welding shrinkage), the general welding sequence for connecting components is as follows: on the plane, it should develop symmetrically from the middle to the surrounding areas, and vertically, the welding sequence should be determined according to the process flow

8) After the installation of beams on each floor of a column, immediately install stairs and profiled steel plates. The stacked materials cannot exceed the load-bearing capacity of the beam and slab.

9) The installation of steel components and the construction of steel-concrete floor slabs should not be separated by more than 5 floors; When it is necessary to exceed 5 floors, it should be verified by the supervising designer.
