Application and Characteristics of Steel Structural Bolts
Steel structural bolts are commonly referred to as steel structural bolt connection pairs in production and manufacturing, but are not generally referred to as high-strength bolts. Steel structural bolts are crucial for the basic construction of industrial production and industrial buildings, railway tunnels, road and highway bridges, pipeline and highway bridges, tower and mast structures, heating furnace structures, heating furnace steel frame structures, large span factories, high-rise residential industrial buildings, various tower bodies, light steel structures, lifting equipment, and other steel frame structure connection engineering buildings. Each connecting pair contains one bolt, one nut, and two sealing rings.
Steel structural bolts are divided into large hexagonal head bolts and torsional shear type bolts based on installation characteristics. The product cost of the compression strength torsional shear type bolt connection pair is high for hexagonal bolts. When assembling the high toughness torsional shear type bolt connection pair, the side of the nut with a circular table should be facing the side of the sealing ring with a chamfer; The high toughness torsion shear type bolt connection pair used in steel frame structure is an improved version of the large hexagonal bolt connection pair in steel frame structure. The key advantage lies in the construction relativity. The hexagonal bolt is simple, and the required indoor space is small. An electric wrench can be used to immediately unscrew the red plum blossom head at the tail end, which is simple and convenient in safety and inspection of construction quality. It does not require technical professionals or machine equipment, It is generally ensured that the construction quality can be ensured by checking and confirming that the red plum flower head has already been twisted off.
The torsional shear type bolt connection pair GB/T3632 includes one bolt, one nut, and one sealing gasket per piece.
When assembling the connecting pair of large hexagonal steel structural bolts, the side with chamfered corners on the sealing ring under the bolt head should face the bolt head;
When constructing high-strength bolts with large hexagonal heads, torque wrenches must be used. The actual operating room space required is large, and it needs to be divided into two sets: initial and final tightening. The construction of relatively torsional shear bolts is more inconvenient;
Quality inspection also requires torque inspection, and requires technical and professional machinery and equipment as well as quality inspection personnel.
The company's main products include high-strength bolts, high-strength nuts, steel structural bolts, steel structural nuts, grid sealing plates, grid bolts, etc.
