Installation control of pre-engineering steel structure building

1) before installation, the construction unit of product certification, design documents and deal with members assembled records for inspection, record the size of the component and the reinspection do not coincide.Deformation of steel structure, defects exceed the allowable deviation, should be handled.
Before the installation, should prepare a detailed measurement and correction of the process, the welding of thick steel plate shall be installed in the welding process test of simulated product structure before, prepare the corresponding construction technology.Wriggle through the earth to assemble good roof should be preset a certain degree.
(2) steel structure hoisting in place, after dealing with components such as design requirements for control point positioning axis, elevation measurement marking, for lifting the butt joint quality inspection before welding.Temporary support wave and steel cable is installed in order to make the security and stability of steel roof in construction process.
