Abstract
The invention discloses a brick wall reinforcing method and structure. The method includes the steps of enabling reinforcing mesh pieces to be attached to the two faces of a brick wall after a paint layer is removed from the surface of the brick wall to be reinforced, fixing the reinforcing mesh pieces on the two sides of the wall body through steel ties, enabling the wall body to be clamped between the reinforcing mesh pieces, and then spraying cement mortar. The wall body and a reinforcing body are connected into a whole, and therefore bearing capacity, lateral stiffness and wall body ductility of the brick wall can be greatly improved. According to the brick wall reinforcing method and structure, a traditional brick wall cross section expanding method is changed for reinforcement, and influences on clearance and attractiveness of a building are small. The method is safe and reliable in technology, easy and convenient to implement and high in operability, and practice shows that the reinforcing effect is good as well.
