Steel plate bonding reinforcement method has been widely used in strengthening engineering, its basic principle is using high performance epoxy adhesive bonded the steel plate to the concrete, so as to form a unified whole,  to achieve the purpose of strengthening and enhancing the strength and stiffness of the original structure.

It has many advantages to reinforce the construction by strengthening the bonded steel plate.

1.sturdy and durable. Through many years' practice of building reinforcement engineering, it is proved that the qualified rate of bonded steel reinforcement project is 100%, which can guarantee the quality of reinforcement engineering, and the strength and rigidity of reinforcement structure can meet the design requirements.

2. simplicity and lightness. Compared with other construction method of reinforcement, steel reinforcement construction is simple, no wet, and thin steel plate, a lightweight, reinforcement of the original structure increased after minimal weight, will not lead to other members of the original structure within the chain of reinforcement.

3. flexible and diverse. The scheme of the bonded steel reinforcement method is diverse, flexible and ingenious. Such as bonded steel, reinforced steel structure and brick masonry structure, etc.

4. the economy is reasonable. Compared with other building reinforcement methods, the cost of reinforcing steel is less and the construction is faster.

But not all building reinforcement can be reinforced by the method of steel bonded reinforcement

1. generally flexural and pulled building structures. (applicable to static force)

2. is suitable for the environment with a temperature of not more than 60 C, a relative humidity of no more than 70% and no chemical corrosion.

3. the concrete strength of the structural members of the original building is less than C15, and it is not suitable to reinforce the steel with sticky steel.

The application of bonded steel plate reinforcement

1.Improve the structural strength of the concrete label;

2. Reinforcement welding point fracture or construction leakage reinforcement;

3. Blast wave damaged beam body reinforcement;

4. Retrofitting and reinforcing of old buildings;

5. Reinforced concrete after fire;

6. Hoisting crane beam to enhance load reinforcement;

7. The beam column is strengthened by chemical corrosion;

8. Bridge crane girder reinforcement;

9. Bridge rupture, old bridge maintenance and reinforcement, etc.
