1. external steel plate reinforcement skills
Strengthening reinforced concrete structural members with steel plates can significantly improve the bearing capacity and damage resistance of the original design. This is because once the steel plate is fixed, the reinforcement of the original structural members will be improved, and the tensile strength, bending and shear mechanical functions of the structural members will also be improved accordingly. These functions are based on the excellent adhesion function of structural adhesive. The steel plate and concrete are firmly connected to form a complete car body, and the tension is effectively transmitted to ensure the joint action.
2. Strengthening technology of carbon fiber fabric sticking outside.
The carbon fiber sheet is connected to the outside of the member through the corresponding connection data, and the spiral dragon wall reinforcement treasure makes the carbon fiber sheet in a tensile state, which is in harmony with the deformation of concrete. The fiber fabric has excellent physical properties, such as high strength, light weight, corrosion resistance and fatigue resistance, as well as excellent adhesion and wide applicability. Strengthening concrete structures with carbon fiber sheets instead of steel plates is common in the world, and it has become more and more in recent years. New skills
3. Increase this part of the strengthening skills.
Also known as the reinforcement ability of external concrete, it is to increase the cross section and reinforcement of components to improve the strength, stiffness, stability and crack resistance of components, and also to repair cracks. It can reinforce plates, beams, columns, roots and frames.
According to different intentions and reinforcement requirements, this skill can be divided into main reinforcement and reinforcement, or both. By strengthening the section reinforcement, in order to ensure the normal operation of additional concrete, the structural reinforcement must be complete. Need reinforcement based on reinforcement. In order to ensure the normal work of steel bars, the section size must be appropriately increased according to the distance of steel bars and the structure of protective layer. In the reinforcement, the reinforcement must be welded and a connection must be established between the new concrete and the old concrete.
4. Plant strengthening skills.
The technology of "planting steel bars", also known as the rooting ability of steel bars, is to drill holes in the original concrete structure, inject structural glue and drill new steel bars in the holes. This ability is widely used in design changes, reinforcement and reconstruction projects, such as beams, columns, cantilever beams and slabs.
This ability of Sparrun wall to reinforce treasures puts forward a method of opening a hole in reinforced concrete structure with a hammer, and taking the reinforcement around the hole as a method to avoid the damage along the structure in construction. Hole-forming technology has been used in plates, cutting walls and central cylinders of many high-rise buildings.
The above is the specific use method of Sibairun wall reinforcement treasure that Bian Xiao told you. When strengthening the building structure, it will also be strengthened and there will be a deeper understanding.
