High-strength bolt connection is one of the commonly used connection methods in modern prefab steel building. It has the advantages of high connection strength, good corrosion resistance, and convenient construction. To ensure the quality and safety of high-strength bolted connections in prefab steel building, a series of regulations need to be followed. This article will focus on the provisions for high-strength bolted connections of steel structures in prefab steel buildings.
Bolt material
Bolt materials should comply with national standards and specifications and be made of high-quality steel to ensure that their mechanical properties and chemical composition meet standards.
The surface of the bolt should be smooth, without cracks, rust and other defects, and should be treated with anti-rust treatment.
Bolted
Bolt connections should use special connectors, such as nuts, washers, etc., to ensure the stability and reliability of the connection.
Bolt connections should be tightened according to the specified torque to ensure the tightness and stability of the connection.
Bolted connections should be inspected and maintained regularly, and damaged bolts and connections should be replaced in a timely manner.
Construction requirements
A comprehensive inspection of the steel structure should be carried out before construction to ensure that it meets the design requirements and quality standards.
Relevant safety regulations should be followed during construction to ensure the safety of construction workers.
Appropriate construction methods and tools should be used during the construction process to ensure construction quality and progress.
After the construction is completed, the steel structure should be comprehensively inspected and accepted to ensure that it meets the design requirements and quality standards.
Quality requirements
The quality of high-strength bolts for prefab steel building should comply with relevant standards and specifications.
The material quality of connectors and bolts should comply with national standards and specifications.
The processing accuracy and surface quality of connectors should comply with relevant standards and specifications.
The tightening torque of bolts should comply with relevant standards and specifications.
The installation position and spacing of connectors should comply with design requirements and quality standards.
The anti-corrosion treatment of connecting parts should comply with relevant standards and specifications.
Relevant safety regulations and operating procedures should be followed during the construction process to ensure the safety and health of construction workers.
After the construction is completed, the steel structure should be comprehensively inspected and accepted to ensure that it meets the design requirements and quality standards.
Connection parts that do not meet quality requirements should be rectified and repaired in a timely manner.
