Construction method for reinforcing existing masonry wall through FRP
The invention relates to the technical field of wall body structure reinforcement, in particular to a construction method for reinforcing an existing masonry wall through FRP, a wall body, an FRP rib material and a protection layer are included, the FRP rib material is arranged on the outer side of the wall body, an adhesive layer is arranged between the FRP rib material and the wall body, the protection layer covers the outer side of the FRP rib material, the protection layer and the wall body are fixed by arranging bolts, and the FRP rib material is arranged on the outer side of the protection layer. The FRP rib material is pasted on the outer wall of the wall body, so that the shear bearing capacity and the shock resistance are improved, and the ductility of the column is improved; the FRP rib materials are pasted on the side face of the wall in the longitudinal and transverse direction or the oblique direction in a crossed and striped mode, the direction corresponds to the main stress direction in the masonry under the action of horizontal force, the masonry is stressed more evenly, the effective constraint area on the masonry is increased, the integrity of the masonry can be maintained, the shear resistance of the masonry is improved, and therefore the reinforcement effect of the masonry is more obvious.
本发明涉及墙体结构加固技术领域，具体为一种采用FRP加固既有砌体墙的施工方法，包括墙体、FRP筋材与保护层，FRP筋材设于墙体外侧，FRP筋材与墙体之间设有粘接胶层，保护层覆盖设于FRP筋材外侧，保护层与墙体通过设置螺栓进行固定，本发明通过在墙体外壁上粘贴设置FRP筋材，提高抗剪承载力和抗震能力，提高柱的延性；通过将FRP筋材纵横向或斜向交叉分条粘贴在墙的侧面，与水平力作用下砌体中的主应力方向相应，使砌体受力更均匀，对砌体的有效约束面积增大，有利于维持砌体的整体性，提高砌体的抗剪能力，从而使得砌体加固效果更明显。
