Concrete structure is affected by the natural environment, and there will be defects such as insufficient bearing capacity and excessive pressure. Therefore, in engineering construction, it is necessary to improve the bearing capacity of the building through maintenance and reinforcement methods. So what concrete structure reinforcement methods are you using?
What are the common concrete structure reinforcement methods?
1. Increase section reinforcement method
It is mainly to increase the cross-sectional size and number of steel bars of the building to improve the bearing capacity of the building structure. It is particularly suitable for the reinforcement of concrete compressive members and has good stability.
2. External bonding steel reinforcement method
It is mainly to wrap the steel on the outside of the building structure and make the steel and the building surface tightly bonded by bonding materials, thereby improving the bearing capacity of the building structure. It is particularly suitable for structural parts that need to greatly increase the cross-sectional pressure resistance.
3. Bonding steel method
It is mainly to bond the steel plate to the concrete structure through epoxy bonding steel glue, so that the steel plate and concrete are integrated. This method is simple and easy to construct.
4. Carbon fiber cloth bonding method
It is mainly to bond the carbon fiber cloth to the surface of the building component through the use of carbon fiber glue. Forming a composite structure to strengthen structural concrete elements.
Carbon fiber not only has high strength and high elastic modulus, but also has the characteristics of light weight and high durability. As a substitute for reinforcing materials in concrete structures, it is widely available for the seismic reinforcement of highway structures, railways and bridge piers, tunnels and buildings.
