Steel structure engineering inspection work is very important to ensure the quality of steel structure workshops and light steel villas. Yili Steel Structure Editor summarizes the steel structure engineering inspection contents for everyone as follows:
First, steel structure material testing
(1) Structural material inspection
The inspection of structural steel materials in Yangang includes the material branch test, cold incubation performance test, fatigue test, hardness test, impact tree test, physical and chemical performance test, etc.
(2) Connection and welding material inspection
The inspection of steel structure connection and welding materials includes the inspection of high-strength bolts, ordinary bolts, anchors, welding rods, welding wires, etc .;
(3) Material testing for steel structure protection
The inspection of materials used for structural protection of steels includes the chemical composition of coatings, physical properties, film surface gloss performance, corrosion resistance, and surface quality of the Xu layer.
Second, steel structure sampling test
When entering the site of the steel structure workshop, the processing of members must be checked to prevent the lending of steel structures of different projects. After the verification is correct, the next procedure can be performed to avoid affecting the subsequent overall progress of the steel structure plant project or assembly errors Quality accident.
Third, steel structure connection detection
The connection detection content of the steel structure includes the following points:
(1) Tight state connection detection. Focus on testing the connection form, number, and configuration, material, looseness and shape, corrosion, fatigue, etc.
(2) Welding connection inspection of steel structure columns, including on-site inspection and non-destructive inspection, on-site splicing, and inspection of installation welds, shall be carried out in accordance with the inspection plan approved by the chief engineer. The minutes of the meeting passed during the discussion shall prevail, and its detection value shall not be less than the lower limit of the specification value.
Fourth, the performance test of the steel structure workshop
The performance testing content of the Yansteel structure workshop mainly includes the following points:
(1) Inspection of structure and component geometry;
(2) Detection of component defects and damages;
(3) Detection of structural member deformation;
(4) Structural inspection;
(5) Anti-corrosion and rust detection of Li structure;
(6) Testing of fire performance of structures.
Fifth, pre-weld inspection of steel structure
Steel structure engineering uses different materials and raw materials. Pre-welding of rods of different materials is required before field assembly. After actual field testing, the design parameters or specifications are compared.
