Steel structure engineering reinforcement method

 What methods are used to reinforce steel structures? Let me tell you:

1. Enlarge the reinforcement of the component section

When using enlarged section to strengthen steel members, the selected section form should be conducive to the reinforcement technical requirements and consider the existing defects and damage. The reinforcement of steel structure engineering needs to be based on actual conditions. In many cases, different parts have different requirements for the quality of reinforcement. Therefore, steel structure engineering should choose appropriate reinforcement methods and conduct reinforcement at different parts.

2. Connection reinforcement and the connection of the reinforcing member

The connection method of steel structure includes welding seam, rivet, ordinary bolt and high-strength bolt connection method, which should be determined according to the reason, purpose, force condition, structure and construction conditions of the structure that needs to be reinforced, and considering the original connection method of the structure. . Steel structure engineering reinforcement should generally be connected by welding seams and friction-type high-strength bolts. When there is a basis, a mixed connection of welded seams and friction-type high-strength bolts can also be used. When welding is used for connection, the qualified welding process and connecting materials shall be used. The connection of steel structure can be divided into welded and non-welded parts. The welded part can be reinforced by welding seam, and the non-welded part can be reinforced by friction type high-strength bolts. If the steel structure engineering requires both of them to be reinforced,Mixed reinforcement can be adopted.

3.Crack repair and reinforcement

When the structure of the steel grid structure has an expansive or brittle fracture tendency due to repeated loads and improper material selection, structure, manufacturing, construction and installation, etc., it should be repaired.

Before repairing, it is necessary to analyze the causes of cracks and the severity of their effects, and take targeted measures to improve the actual work of the structure or to strengthen the structure. The components that are not suitable for repair and reinforcement should be removed and replaced. Due to the pressure of different loads on the steel structure space frame, many steel components are damaged to varying degrees.

Therefore, when the steel structure is a space frame, the damaged steel components can be replaced and then reinforced to improve the overall quality of the steel structure project.
