Installation characteristics of steel structure bolt
Steel structural bolts in the production of the full name of the steel structure bolt connection, generally not referred to as high-strength bolts. Steel structure bolt is mainly used for industrial and civil buildings, railway bridges, highway bridges, bridges, pipelines, boiler tower frame, boiler steel structure, large span industrial workshop, high-rise buildings, tower, light steel structure, lifting machinery and other steel structure connecting building construction.
Each connection pair includes a bolt, a nut, and two washers. According to the characteristics of installation, the steel structure bolt is divided into six big head bolts and torsional shear bolts. High strength torsion type bolt nut assembly, side with round surface should be toward the side of the chamfered washer; steel structure with high strength, torsion and shear type bolt connection of steel structure is improved by six angle bolts, the main advantage is the construction of six large angle bolts is simple, small space required for construction the use of electric wrench, directly to the tail of the plum blossom head can twist off the safety, simple and quick, and check the construction quality is very convenient, no professional personnel or equipment, only the general visual inspection confirmed the plum blossom head has been twisted off to ensure construction quality.
But the production cost of the strength and shear type bolt joint is larger than that of the six angle bolt. Torsional shear type bolt connection GB/T3632 each with a bolt, a nut, a gasket. Six hexagon head bolt for steel structure assembly, one side of the chamfered washer bolt head towards the bolt head; six hexagon head high strength bolt construction requires the use of a torque wrench, the required operation space, should be divided into initial and final screwing two to complete the construction, relative torsional shear bolts some trouble quality inspection; also need to check, need professional equipment and quality inspection personnel.
