Key points of steel structure construction
2023-01-31
(1) There should be a construction process or plan, measurement and correction, high-strength bolt installation, negative zero degree construction and welding process, etc. should be tested or evaluated before installation.
(2) The detection of installation deviation should be carried out after the structure forms a spatial stiffness unit and connects and fixes.
(3) During installation, the construction load of roof, wall platform and other construction loads must be controlled, and ice and snow loads are strictly prohibited to exceed the bearing capacity of beams, trusses, floor panels, roof panels and platform laying.
(4) After the formation of the space unit, the voids of the column floor and the top surface of the foundation should be timely poured with fine stone concrete, grout, etc. (pad with steel pads, spot welding thickness not exceeding 5 pieces).
(5) Suspension objects and fixtures shall not be welded on the crane beam or beam directly bearing the dynamic load, the tensile flange, the crane truss or the truss directly bearing the dynamic load and its tensile chord.
