Reinforcing method for shear wall structure
The invention relates to the technical field of shear wall reinforcing, in particular to a shear wall structure reinforcing method which comprises the steps that a special support is erected and used for supporting beams and plates of an original structure; popping out a concrete replacement range sideline according to the design drawing; an original concrete shear wall is chiseled away through the rope saw technology, soil residues are cleaned, steel bars are trimmed, and formworks are erected; concrete on the original steel bars is removed, and the damaged steel bars are subjected to steel bar planting repairing and binding; pipelines are pre-buried and installed according to design before construction; a concrete formwork is erected, and a wall formwork is built; a high-strength micro-expansion grouting material is poured into the mold, and the mold plates are hit by hammers on the two sides in combination with an attached vibrator to assist in pouring; the concrete is maintained regularly after the formwork is removed, and acceptance inspection is conducted after maintenance is conducted for 14 days; the old building is renovated and reinforced by chiseling off the original shear wall and replacing the original shear wall, so that the construction process is simple, the construction period is shortened, and the stability of the building is improved on the premise of ensuring the construction safety.
本发明涉及剪力墙加固技术领域，具体涉及一种剪力墙结构加固方法，包括搭设特制支撑，用于对原结构的梁、板进行支撑；根据设计图纸弹出混凝土置换范围边线；利用绳锯技术凿除原混凝土剪力墙，并清理土渣、修整钢筋以及进行模板支设；清除原钢筋上的混凝土，对损坏的钢筋进行植筋修复、绑扎；在施工前根据设计预埋安装管道；支设混凝土模板，搭建墙体模板；采用高强微膨胀灌浆料浇筑入模，两侧用锤振击模板结合附着式振动器辅助浇筑；拆除模板后定期对混凝土进行养护，养护14天后验收；通过凿除原剪力墙并置换的方式，对老旧建筑进行翻新加固，在保证施工安全的前提下令施工工序简单，缩短施工工期，提升构筑物稳固性。
