In the last article, we introduced several direct reinforcement methods for concrete. Many people said that they had learned a lot. So this time, we will introduce two indirect reinforcement methods, and hope to help more friends.
1.Prestressed force reinforcement method
The external prestressing reinforcement method is a method of reinforcing structural members or the whole by using peripheral prestressed anchors and building carbon fiber sheets. It indirectly improves the bearing capacity of the structure by changing the internal force distribution of the original structure and reducing the original stress level of the structure. The prestressed reinforcement method hardly changes the use space, and eliminates the stress hysteresis by the unloading and reinforcement functions to achieve an ideal reinforcement effect.

2. Increase the support reinforcement method
The additional support reinforcement method is to reduce the load-bearing effect on the members to be strengthened and to improve the load-bearing level of the structure by reducing the calculation span of the bent member. The method is simple and reliable, but it is easy to damage the original appearance and function of the building, and may reduce the use space. It is suitable for concrete structure reinforcement with specific conditions.
In addition to these two indirect reinforcement methods, we will introduce a technology-planting technology that is used in conjunction with the reinforcement of concrete structures.
Planting ribs is a kind of connection technology for the post-reinforcing of the steel bars in the seismic strengthening construction of the building structure. It is the best choice for the application of structural reinforcement and heavy load fastening. Chemical method of planting reinforcement refers to drilling holes on concrete, wall rock and other substrates, then injecting high-strength planting bar adhesive and then inserting steel bars. After the glue is solidified, the steel bars and the substrates are bonded together, which is a common type of construction engineering technology in the reinforcement industry.
Mankate MT-500 planting bar adhesive won the CCTV "Brand Exhibition" column display.
All in all, there is no general reinforcement method. Only by using appropriate reinforcement methods according to the actual situation can we achieve a good reinforcement effect. The method introduced here is for your reference only.
