What are the wall reinforcement measures?

When there is concentrated load on the wall between windows, and the wall thickness is not enough to bear its load; Or when the length and height of the wall exceed a certain limit, which affects the stability of the wall, pilasters protruding from the wall are often added at appropriate positions in the wall to improve the rigidity of the wall. When making a doorway in the wall, or at the corner of two walls or at the junction of T-wall, in order to facilitate the placement of the door frame and ensure the stability of the wall, a crib must be set at the corner of the door against the wall or at the junction of T-wall.

2. Set the ring beam

Ring beam is a continuous closed beam around the outer wall and part of the inner transverse wall. The combination of ring beam and floor can enhance the spatial stiffness and integrity of floor plane, reduce the wall cracking caused by uneven settlement of foundation, form a skeleton with constructional column and improve the seismic capacity.

3. Anti-seismic measures

Because brick masonry is a brittle material, its seismic capacity is poor. Therefore, in the seismic fortification area above 7 degrees, there are certain restrictions and requirements on the total height of brick masonry buildings, the spacing between transverse walls, the setting of ring beams and the local size of walls, which must be considered in accordance with the seismic design code. In addition, in order to enhance the overall stiffness and stability of the building, it is also required to improve the strength grade of masonry mortar and adopt reinforced concrete structural columns when necessary. Reinforced concrete structural columns are set from the structural point of view, generally located in the four corners of buildings, the junction of internal and external walls, stairwells, elevators and some long walls. The constructional column must be closely connected with the ring beam and wall to form the spatial skeleton of the whole building. So as to enhance the stiffness of the building, improve the strain capacity of the wall, and make the wall change from brittle to ductile structure, so as to crack without falling down. During construction, the wall must be built first, and the reinforced concrete column body is poured in place section by section with the rise of the wall.
