一、作用和适用范围采用夹板墙加固多层砖房墙体是常用的抗震加固方法之一。当砖墙抗剪强度不满足要求,又不宜采用增加抗震墙的方法加固时,均适用夹板墙加固法。所谓“夹板墙”是指去掉砖墙的粉刷抹灰层,在砖墙一侧或两侧面抹高标号水泥砂浆,或设置钢筋网再抹高标号水泥砂浆,或喷射混凝土对墙体进行的加固,以提高墙体的抗剪强度和房屋的抗震能力。检查砖墙的质量,凡砖墙由于长期使用
First, the role and scope of application Using plywood wall reinforcement multi-storey brick house wall is one of the commonly used method of seismic reinforcement. When the shear strength of the brick wall does not meet the requirements and it is not appropriate to use the method of increasing the seismic wall, the plywood wall reinforcement method is applicable. The so-called “plywood wall” refers to the removal of the stucco plastering layer of a brick wall, and the use of high-grade cement mortar on one or both sides of the brick wall, or the setting of reinforced mesh and then high-grade cement mortar, or sprayed concrete to reinforce the wall. In order to improve the shear strength of the wall and the earthquake resistance of the house. Check the quality of brick walls, where brick walls are used for a long time
