The invention does not need to modify and upgrade the existing equipment during operation, has easy and simple operation, is convenient for actual operation of workers, and effectively ensures the perforation rate of the high-strength bolts of the on-site beam column.
Description
Technical Field
The invention belongs to the connection, manufacturing and processing of steel structure beams and columns, and particularly relates to a method for ensuring the perforation rate of high-strength bolts of a steel structure.
Background
The high-strength bolt is connected with the steel structure after rivet connection and welding, and has the characteristics of simple and convenient construction, rapidness, easiness in mastering, detachability and replacement, good stress performance, high bearing capacity, safety, reliability and the like, so that the high-strength bolt is developed into a common method for connecting and applying the steel structure building. In particular, overseas projects, they claim as little as possible welding on site, all by bolting. For this reason, all the steel columns, the steel beams, the vertical supports, the horizontal supports and other members are connected by high-strength bolts, and the number of the high-strength bolts is large. Therefore, the manufacturing precision of the high-strength bolt connection structure plays an important role in field installation, and the procedures of component assembly, high-strength bolt hole making, pre-assembly and the like must be strictly controlled.
