Torsion shear bolt connection pair for steel structure

The torsion shear bolt connection pair for steel structure is an important connection piece used to connect steel structure components. It has the advantages of strong bearing capacity, easy installation and good seismic performance. The following will introduce the relevant information of the torsion shear bolt connection pair for steel structure in detail.

1. Introduction:

The torsion shear bolt connection pair is a fastener specially used to connect steel structure components. By tightening the bolts and nuts, a certain pre-tightening force is generated between the components, thereby achieving a firm connection of the components. The torsion shear bolt connection pair is usually composed of torsion shear bolts, nuts, washers and other components.

2. Material:

The material of the torsion shear bolt connection pair is usually carbon steel or alloy steel, which has good strength and toughness and can meet the bearing requirements of steel structure connections. At the same time, different surface treatment methods can be selected according to the specific usage scenarios, such as galvanizing, hot-dip galvanizing, phosphating, etc., to improve the corrosion resistance of the connection parts.

3. Process:

The manufacturing process of the torsion shear bolt connection pair mainly includes cold heading, heat treatment, surface treatment and other links. During the cold heading process, wire drawing can be performed according to bolts of different specifications to improve the strength and precision of the bolts; the heat treatment link can adjust the hardness and toughness of the bolts by controlling the heating temperature and cooling speed; the surface treatment is to improve the corrosion resistance and aesthetics of the connector.

4. Parameters:

The parameters of the torsion shear bolt connection pair mainly include the diameter, length, thread specification, bolt grade, etc. of the bolt. Usually, the appropriate bolt specification and grade are selected according to the thickness of the connected components and the load-bearing requirements to ensure the reliability and safety of the connection.

5. Application scenarios:

Torsion shear bolt connection pairs are widely used in steel structure buildings, bridges, tower cranes, steel frame structures and other fields to connect beams, beams, columns and other components. In construction projects, torsion shear bolt connection pairs can effectively improve the construction efficiency and connection quality of the project, and can also meet the connection requirements of different structural systems.

In short, the torsion shear bolt connection pair for steel structure is an important connector with the advantages of strong bearing capacity, easy installation, good seismic performance, etc., and is suitable for various steel structure connection scenarios. In future construction projects, torsion shear bolt connection pairs will continue to play an important role and promote the development and progress of steel structure buildings.
