For the reinforcement technology of steel structures, there are nothing more than three aspects.

The first aspect is to relieve the load of the structure itself from various aspects. However, for a project with a fixed structure, it is impossible to reduce the load caused by its own gravity or its own factors. The only way to reduce the load is to reduce the external load.

The second aspect is to strengthen and change the force system of the structure, so that the force of the structure and the system of transmission force are changed, so as to achieve the purpose of reducing the load force. But since this method is more complicated. Changing the force system of the structure means redesigning the structure, including making substantial changes to the structure, so as to achieve the ideal force system. For some relatively large large-scale structures, this method will inevitably lead to waste of human, material and financial resources. Although the reinforcement effect is good, it is generally not applicable.

The third aspect is to reinforce the steel structure from the nodes or components. The reinforcement of steel structures can not only solve the problems of short service life and insufficient structural firmness. Since it is only operated locally, it can save a lot of time and cost and achieve the desired effect.

Application of Glue Injection Bonding Steel Reinforcement Technology

1. Application in Bridge Crack Reinforcement

In many bridge structures, the actual service life of many bridges does not reach the expected service life. One of the most important reasons is the cracks in the middle of the bridge due to the fatigue of the bridge. The solution to this problem is to fill and strengthen the bridge cracks, thereby extending the service life of the bridge. The main operation steps are to first clean the residual sand and gravel at the bottom of the crack, then bond the steel plate, then inject glue into the middle of the crack, and then raise it to about 50 degrees, and the bonding work is basically completed.

2. Application of Glue Injection Bonding Steel Reinforcement Technology in Seismic Reinforcement

The principle of this process is to weld the steel frame on the surface of the reinforced concrete, and finally seal it with sealant. Finally, glue is injected inside, and after the colloid solidifies, the steel frame of the outer layer and the reinforced concrete inside form a whole, so as to achieve the effect of increasing earthquake resistance.

This method of the project reinforces the building and the house, which can avoid the reconstruction of the house. Only this method can achieve the ideal earthquake resistance effect, so it can save money. After experimental analysis, the reinforcement technology can greatly improve the stability.
