Construction method for detachable support of steel-concrete composite beam cantilever cast-in-place slab
The invention discloses a steel-concrete composite beam cantilever cast-in-place slab detachable support construction method. The method comprises the following steps that firstly, when a steel main beam is manufactured, tuyere mounting holes are formed in a stiffening plate on the outer side of an outer web of the steel main beam; 2, when the suspension casting support is machined, a suspension casting support mounting hole is formed; thirdly, a suspended pouring support is installed before the steel main beam is hoisted; fourthly, after the steel girders are positioned, a personnel operation platform and a cast-in-place slab adjusting support are erected; and fifthly, all the jacking heights of the cast-in-place slab adjusting support are adjusted, a bottom formwork is installed, reinforcing steel bars are bound, the steel wedge blocks are fixed, and then concrete is poured. The problem that after the steel main beam is positioned at a high altitude, a support cannot be erected on a cast-in-place slab cantilever part for pouring is solved, and a detachable support composed of a suspended pouring support, a cast-in-place slab adjusting support, a steel wedge block and the like is fixed through tuyere mounting holes in a stiffening plate on the outer side of an outer web of the steel main beam and bolts to serve as a cast-in-place slab cantilever part supporting platform. Welding damage to the steel main beam is not needed, and mounting and dismounting are convenient.
本发明公开了一种钢混结合梁悬臂现浇板可拆装式支架施工方法，步骤如下：步骤一：钢主梁制造时钢主梁外腹板外侧加劲板设置风嘴安装孔；步骤二：悬浇支架加工时设置悬浇支架安装孔；步骤三：钢主梁起吊前安装悬浇支架；步骤四：钢主梁定位后，搭设人员操作平台和现浇板调节支架；步骤五：调整现浇板调节支架所有顶托高度，安装底部模板，绑扎钢筋，固定钢楔形块后，浇筑混凝土。本发明解决了钢主梁高空中定位后，现浇板悬臂部分无法搭设支架浇筑的问题，利用钢主梁外腹板外侧的加劲板上的风嘴安装孔，螺栓固定由“悬浇支架、现浇板调节支架、钢楔形块”等组成的可拆装式支架作为现浇板悬臂部分支撑平台，无需对钢主梁造成焊接损伤、安拆方便。
