High strength bolt joint project
 
High strength bolt connection is also one of the most important items of steel structure engineering, and it is also one of the weak links of construction quality at present
(1) high strength bolts are shoddy phenomenon (using an ordinary refined bolts instead of the high strength bolts);
(2) the treatment of high strength bolt joint surface can not meet the requirements of specifications, including surface treatment, formation, sealing, bolt hole quality and so on;
(3) the application of high strength bolts shall not be carried out according to the specifications. If they are finished at the beginning and end of the screw, no torque wrench or subjective evaluation shall be adopted. In order to ensure the construction quality of high strength bolt connection project, engineers must have a high degree of responsibility, strengthen supervision in the contracting units to improve the quality consciousness, quality management, the implementation of quality assurance measures, actively adopt on-site supervision, parallel inspection work method, construction quality is the only way to make the connection of high strength bolt under the strict control
