The installation of steel structures

The installation of steel structures and the general structure of the installation is common. There are differences.
Installation of steel structure installation of equipment selection, site wide cloth, safety measures and precast reinforced concrete structure
Similar. The difference is some preparatory work before installation, installation of the stability and connection problems.
(a) steel structure installation preparation
1 construction organization design
The construction organization design of steel structure installation should be situation, briefly describe engineering comprehensive engineering quantity statistics, the correct choice of construction machinery and construction methods, reasonable layout, with the drafting of the main installation sequence installation technology, strict measures of installation quality standards and safety standards, careful preparation of project schedule, workforce planning and material supply plan.
Before installation, check the 2 gun
Retest check before installation comprises a steel member approval, construction equipment and measuring instrument test and foundation.
(two) the stability problems of steel structure installation
Steel structure is used in the specific condition. In a relatively random construction conditions, stability conditions of the system or component will change greatly. So when installed, should give full consideration to the overall stability of it in various conditions component monomer stability and structural problems, in order to ensure the safety of construction.
Component monomer stability problem refers to a component in the site piled up, pulling, lifting, bending, bending torsion emplacement occurred in the process of failure and instability. Therefore, for a thin and components of larger size shall consider this problem. When necessary to reinforce the weak axis component with temporary support. Such as a plane truss and the ratio of height to width of considerable I-beam etc..
