Masonry structures are building structures that are constructed by building load-bearing structural walls with mortar, mainly from components such as bricks or other blocks, and are widely used in the industrial and civil construction fields. However, the masonry structure has poor seismic performance and is easily damaged when an earthquake occurs. Therefore, there is a need to reinforce existing masonry structural walls to improve their seismic performance.
The reinforcing mesh cement mortar reinforcing method is characterized in that a reinforcing mesh cement mortar surface layer is arranged on the surface of the masonry structure wall body, so that the integrity of the wall body can be improved, the strength of the wall body is increased, and the reinforcing mesh cement mortar reinforcing method is applied to the reinforcement of the masonry structure wall body. For example, chinese patent application CN103835521A discloses a method for reinforcing a brick wall, which comprises removing a whitewash layer from the surface of the brick wall to be reinforced, attaching reinforcing mesh sheets to both sides of the brick wall, fixing the reinforcing mesh sheets at both sides of the wall by using tie bars, sandwiching the wall between the reinforcing mesh sheets, and spraying cement mortar. The wall body and the reinforcing body are connected into a whole, so that the bearing capacity, the lateral stiffness and the wall body ductility of the brick wall can be greatly improved.
However, the wall and the foundation of the masonry structure building have poor shear resistance and bending resistance, so that the wall and the foundation are prone to crack during an earthquake, and the wall is prone to damage after displacement. Only adopt reinforcing bar net cement mortar reinforcement method though can strengthen the wholeness of wall body, can not strengthen being connected between wall body and the basis, in addition, reinforcing bar net piece can only rely on the drawknot reinforcing bar between the both sides to fix, and under the relatively poor condition of brickwork intensity, reinforcing bar net piece also is difficult to obtain better fixed effect.
In addition, in the existing masonry structure building, the existing foundation is arranged deeply, and if excavation is performed for effectively connecting the wall body with the foundation, the existing foundation is vibrated due to the deep excavation depth, which is disadvantageous.
Therefore, it is necessary to provide a new anti-seismic reinforcing structure to ensure the safety of the masonry wall.
