Main inspection contents in steel structure engineering
Main inspection contents in steel structure engineering: The components used in steel structures are generally mass-produced by steel mills and are required to have certificates of conformity, so the strength and chemical composition of the materials are well guaranteed. The focus of engineering inspection is on the quality problems generated during the installation and splicing process. The main testing contents in the steel structure project are: (1) Detection of member size and flatness; (2) Detection of surface defects of members; (3) Detection of connection (welding, bolting); (4) Detection of steel corrosion; (5) Fireproof coating thickness test. If there is no factory certificate of conformity for the steel, or if there is doubt about its quality, the mechanical properties test of the steel should be increased, and if necessary, its chemical composition should be tested. (1) Detection of member size and flatness For each size in the member of the 3 parts of the meas...
