The steel structure house represents the new pattern of residential development in the future. Its advantages are: greatly save the construction time, not affected by the season; Enlarging housing
       Space use area; Reduce construction waste and environmental pollution, building materials can be reused; Promote the development of other new building materials industry; Good seismic performance; use
       Easy to transform, flexible and convenient; Give people comfort and so on.
       1. Process flow chart of steel structure installation before installation and construction of high-rise steel structure
       2. Reasonably divide the construction flow section;
       3. Determine the installation sequence of steel components;
       4, in the case of crane lifting capacity allows, can be assembled on the ground structure as far as possible on the ground assembly, such as steel column and steel support, steel truss assembly, can be lifted in place;
       5, installation of water section, can be divided according to the steel structure building plane shape, structural form, construction period, site construction conditions and the number of installation machinery range;
       6, component installation sequence, the plane should be from the middle core area, namely the standard frame to the four sides of the development, vertical should be installed from the bottom up one by one;
       7, flow section, component installation, correction, fixing practices (including reserved welding shrinkage, after the determination of general component welding sequence: the plane should be symmetrical development from the middle to the periphery, vertical according to the process process to develop the welding sequence
       8. After the installation of beams on each layer of a column, install stairs and molding steel plates immediately. The pile shall not exceed the bearing capacity of the beam plate.
       9, steel component installation and floor steel concrete construction, the two operations should not be more than 5 layers apart; When it must be more than 5 layers, it should be checked by the designer in charge.
