1. Application of Industrial Bolt Factory's steel structure bolts
  Steel structure bolts are mainly used for steel structure engineering, and are used to connect the connection points of steel structure steel plates. Steel structural bolts are high-strength bolts and standard components. Better fastening performance, used in steel structure and engineering to achieve the fastening effect. In the general steel structure, the required steel structure bolts are all above 8.8, there are 10.9 and 12.9, which are high-strength steel structure bolts. Sometimes the bolts on the steel structure do not need to be plated.
  Second, steel structure bolt classification
  Steel structure bolts are divided into torsion-shear high-strength bolts and large hexagon high-strength bolts.The large hexagon high-strength bolts belong to the high-strength level of ordinary screws, while the torsion-shear high-strength bolts are improved types of large hexagon high-strength bolts for better construction.
  Three, steel structure bolt construction
The construction of the steel structure bolts must be tightened first and then the final tightening.The initial tightening steel structure bolts need to use impact type electric wrench or torque adjustable electric wrench; while the final tightening steel structure bolts have strict requirements, the final tightening torsion shear type steel structural bolts must Use torsional shear type electric wrench, and the final tightening torque type steel structure bolt must use torque type electric wrench

  Characteristics of steel structure
  Steel structure system has comprehensive advantages such as light weight, factory manufacturing, fast installation, short construction period, good seismic performance, fast investment recovery, less environmental pollution, and high degree of industrialization. Compared with reinforced concrete structure, it has more unique advantages. Globally, especially in developed countries and regions, steel structures are widely used in various engineering constructions, such as steel bridges, steel workshops, steel gates, various large pipeline containers, high-rise buildings and tower rail mechanisms.
  Technical process of steel structure installation
   1. According to the normal installation sequence and process requirements, prefabricating and assembling the steel structure on the steel platform must ensure the quality of welding.
  2. The distance between the splice flange joints of the profiled steel and the splice joints of the web should be greater than 200mm. Flange panel splice length cannot be less than 2 times the width of the plate; web splice width should not be less than 300mm, and the length should not be less than 600mm.
  3. In order to facilitate the welding and ensure the welding quality, as far as possible, the stiffener plates, connecting plates, backing plates, beams, etc. on the pillars, beams, etc. are grouped and welded on the ground steel platform according to the construction drawing size.
  4. In addition to the fabrication and assembly of steel components prefabricated on the steel platform by China Stud Supplier in accordance with the construction drawings and specifications, it is also necessary to consider the changes in on-site installation processability and installation dimensions.
