Application and characteristics of steel structure bolts

In the production and manufacture of steel structure bolt, it is called steel structure bolt connection pair, but it is not called high strength bolt. Steel structure bolts are used for the basic construction of industrial production and industrial buildings, railway tunnels, road and highway bridges, pipeline highway bridges, tower mast structure, heating furnace structure, steel structure of heating furnace, large span workshop, high-rise residential industrial buildings, various tower bodies, light steel structures, lifting equipment and other steel frame structure connection engineering buildings. Each coupling pair consists of a bolt, a nut and two sealing rings.
According to the installation characteristics, steel structure bolts are divided into large hexagon head bolts and torsion shear bolts. The product cost of compression strength torsional shear bolt connection pair is very high, and the hexagonal bolt is high. When assembling the high toughness torsional shear type bolt connection pair, the side of the nut with round table should face the side with the fillet of the sealing ring; the high toughness torsional shear bolt connection pair for steel frame structure is an improved version of the large hexagon bolt connection pair of the steel frame structure. The key advantage depends on the construction relativity. The hexagonal bolt is simple and the construction room space is small. The electric wrench is used to immediately remove the end of the bolt The red plum flower head can be twisted off. The safety is simple and convenient, and it is very convenient to check the construction quality. It is not necessary to use technical professional staff or machinery and equipment. It is only by looking at the inspection and confirming that the red plum flower head has been twisted off, which can ensure the construction quality.

Each pair of torsional shear bolt connection GB / t3632 contains one bolt, one nut and one gasket.
When assembling the bolt connection pair of large hexagon head steel structure, the side with fillet under the bolt head should face the bolt head;
The torque wrench must be used in the construction of large hexagon head high strength bolts. The actual operation room space required is large, and it should be divided into two sets of initial tightening and final tightening, so the construction of relative torsion shear bolts is inconvenient;
Quality inspection must also be torque inspection, technical professional machinery and equipment and quality inspection staff.  
The company's main business: high strength bolt, high strength nut, steel structure bolt, steel structure nut, grid sealing plate, grid bolt, etc.
