The full name of steel bolts in the production is called steel structure bolt connection. Generally not simply called high-strength bolts. Steel structure bolts are mainly used in industrial,civil construction, railway bridge, highway bridge, pipeline bridge, tower mast structure, boiler frame, boiler steel structure, large span industrial building, high-rise civil building, various tower, light steel structure, heavy machinery and other steel structure connected building construction.
Each coupling pair includes a bolt, a nut, and two washers. According to the installation chracterastic, there are two type of steel structure bolt connection.They are hexagon bolts and torsional shear bolts. High-strength torsional shear bolt-type vice-assembly, the nut with a round table side should be towards the gasket side of the chamfer. Steel structure with high-strength torsional shear bolt connection is a large hexagon bolts steel connection improved. The main advantage is construction of large hex bolts is simple. It requires small construction space.Electric wrenches directly twisted off the tail of the plum blossom head,which is safe and quick. Also checking the construction quality is very convenient. No need of professionals or equipment, just general visual inspection to confirm plum blossom head has been twisted to ensure construction quality.
The strength of the torsional shear type bolts to connect the production cost of the larger hexagon bolts high. Torsional shear type bolt connector GB / T3632 Each set contains a bolt, a nut, a gasket. Large hexagonal head bolted steel joint assembly, the bolt head under the gasket chamfer side should be facing the bolt head. Large hexagonal head high-strength bolts need to use torque wrench construction, which requires operating space and twisting two completed, the construction of some of the relative torsional shear bolt trouble. Quality inspection also need to check the torque,which need professional equipment and quality control personnel.
