Construction method for existing building basement frame column externally penetrating shear wall
The invention relates to the technical field of building construction, in particular to a construction method for an existing building basement frame column externally penetrating through a shear wall. The method comprises the following steps: acquiring plane positioning of a newly-added column; an unloading supporting frame is erected on the inner side of the shear wall needing to be reserved; the shear wall structure needing to be broken is broken through the combination of a water drill and a wire saw; column embedded steel bars including column main steel bars and column stirrups are additionally arranged on a bottom plate and a wall column of the broken shear wall; after the newly-added column is planted with the steel bars, a column formwork is arranged outside the steel bars and reinforced; and concrete is poured into the column formwork, and the newly-added column is obtained. By means of the construction method, the overall reconstruction quality of the project is effectively guaranteed, the construction process can be in a safe, stable, rapid and controllable state, and smooth completion delivery of the project is promoted.
本发明涉及建筑施工技术领域，尤其是涉及一种既有建筑地下室框架柱外穿剪力墙施工方法。所述方法，包括获取新增柱的平面定位；在需保留的剪力墙内侧搭设卸载支撑架；通过水钻结合绳锯破除需破除的剪力墙结构；在破除剪力墙的底板和墙柱上新增柱植筋，包括柱主筋和柱箍筋；新增柱植筋后，在钢筋外设置柱模板并加固；向柱模板内浇筑混凝土，得到新增柱。本发明通过该施工方法，有效保障了工程整体改造质量，且能够使施工过程处于安全、稳定、快速的可控状态，促进工程顺利竣工交付。
