Improve aseismic performance of the brick concrete structure
The aseismic performance of the brick concrete structure is generally poor, its cross wall space is too large, it is not satisfied with the requirements of the standard, the bearing capacity is insufficient, the width of the house is not satisfied, the length of the window wall is not enough, and so on.
The aseismic performance of the brick concrete structure is generally poor, its cross wall space is too large, it is not satisfied with the requirements of the standard, the bearing capacity is insufficient, the width of the house is not satisfied, the length of the window wall is not enough, and so on.
For brick and concrete structures, the following reinforcement measures can be adopted.
1. the opening of the brick door and window. When the doors and windows of the doors and windows are large and large, the seismic performance of the building structure is too weak. Blocking the original opening can improve its seismic capacity.
2. the splint wall is set up. The splint wall can be reinforced by one side or two sides, with reinforcement net cement mortar splint wall and reinforced concrete splint wall. The splint wall is connected with the ceiling or floor, the upper and lower reinforcement should be pulled as far as possible, and the two sides must have reliable connection with the pulse wall and the reinforced wall.
3. reducing the layer and lowering the height. The main component of brick and concrete structure is the brick wall, and the brick wall itself has the disadvantages of poor shear resistance, small deformation and poor ductility. It is easy to destroy in the earthquake. With the increase of storeys and height, the seismic response is also intensified.
4. the column and the beam are added. The cast-in-place concrete wall column, ring beam and inner wall pull rod form the whole, and become the outsourcing frame. Even if there is no column only without columns, the overall seismic performance of the concrete can be greatly improved.
5. pressure grouting. It is mainly aimed at cracks in brick walls which affect the appearance of cracks and affect the strength. They can be repaired by water glass mortar and other materials.
6. set steel pull rod. When the inner wall needs additional girth and can not be set up, the steel tie rod can be used instead of the ring beam.
