Hex Bolt Manufacturers introduced the requirements of high-strength bolts on the joint fusion surface:
1. When the high-strength bolts are tightened, the connecting plate and the connecting matrix generally have to go through a key process of "sandblasting" or "shot blasting" two processes to solve the problem, and must be used in the transportation and construction sites. Make sure to check the surface roughness and cleanliness of the fusion surface before construction. According to regulations, a little bit of soil and debris environmental pollution is not allowed
Fusion surface.
2. When the roughness of the fusion surface of the high-strength bolt fails to meet the requirements of the design plan, sand blasting or shot blasting must be carried out on the spot again, and then the construction work can be carried out. The installation company should pay attention to the cleanliness and frictional surface characteristics of the connecting plate and the connecting surface of the parent body where the high-strength bolts are connected.
3. The high-strength bolt connection pair is manufactured and delivered by the manufacturer in accordance with the batch number and the supporting facilities. Therefore, the high-strength bolts should have a product certificate. The form, specifications and technical standards of the high-strength bolt connection pair should meet the requirements of GB1228-1231-91 (large hexagon). When applying the composition, it must meet the requirements of the national industry standards.
For engineering construction, the high-strength bolt connection pair needs to be stored, transported and supplied with supporting facilities in the same batch. The high-strength bolt connection pair should be installed and handled with care during the whole process of loading, loading and unloading vehicles, transportation and storage, to avoid damage to the packing wooden box and damage to the anchor bolts.
Through the above introduction, Stud Bolt Supplier hopes that you can simply refer to the content of this article in future use.
