Existing building masonry load bearing wall reinforcing structure and construction method thereof
The invention discloses an existing masonry load bearing wall reinforcing structure. The existing masonry load bearing wall reinforcing structure comprises a masonry load bearing wall and a steel reinforcement framework, a plurality of through-wall holes are formed in the masonry load bearing wall, the steel reinforcement framework comprises steel reinforcement meshes which are arranged on the two faces of the masonry load bearing wall and steel tie bars which are connected with the steel reinforcement meshes on the two faces, the steel reinforcement meshes are formed by binding longitudinal reinforcing steel bars and horizontal reinforcing steel bars according to a preset interval, after the tie steel bars penetrate through the through-wall holes, the two ends hook the steel reinforcement meshes on the two faces of the masonry load bearing wall respectively, the through-wall holes are filled with expansion mortar, and the two faces of the masonry load bearing wall are covered with a layer of concrete spraying layer. Compared with the prior art, the invention provides a treatment method of an existing old building, compared with traditional abandonment or direct demolition reconstruction, the structural bearing capacity and safety requirements after reinforcement and reconstruction are met, new use functions can be provided for the existing building, sustainability of the existing building engineering is facilitated, and the purpose of comprehensive utilization of the existing building is achieved.
本发明公开了一种既有砌体承重墙加固结构，包括砌体承重墙与钢筋骨架，所述砌体承重墙上设置有若干穿墙孔洞，所述钢筋骨架包括设置在砌体承重墙两面上的钢筋网片与连接两面钢筋网片的拉结钢筋，钢筋网片由纵向钢筋与水平钢筋按照预设间距绑扎形成，拉结钢筋穿过穿墙孔洞后两端分别勾住砌体承重墙两面的钢筋网片，所述穿墙孔洞内通过膨胀砂浆进行填充，所述砌体承重墙的两面上覆盖有一层混凝土喷射层。与现有技术相比，本发明提供了一种既有老建筑的处理方法，与传统废弃或直接拆除重建比，在满足了加固改造后的结构承载力和安全性要求；又能提供既有建筑物新的使用功能，有利于既有建筑工程的可持续性，达到既有建筑的综合利用的目的。
