Hanging construction method for overhanging and downward-hanging type cast-in-place slab
The invention relates to a hanging construction method for an overhanging and downward-hanging type cast-in-place slab. The hanging construction method includes the steps that step 1, a formwork jig frame is assembled; step 2, an upper-layer steel beam and a lower-layer steel beam are hoisted to the corresponding positions of a steel column and installation is finished; step 3, the assembled formwork jig frame and the lower-layer steel beam are fixed together; step 4, a wire tightening buckle is arranged on a sling, the lower end of the sling is fixed to the formwork jig frame, the upper end of the sling is fixed to the upper-layer steel beam, and the sling is initially tightened through the wire tightening buckle; step 5, battens are laid on the formwork jig frame, and formworks are laid on the battens; step 6, structural steel bars are laid on the formworks, and concrete is poured and tamped; and step 7, after the strength grade of the concrete meets the requirement, firstly the wire tightening buckle is loosened, then the formwork jig frame is disassembled, then the battens and the formworks are disassembled, and finally the sling is disassembled, so that the construction of the layer of the overhanging and downward-hanging type cast-in-place slab is completed. The hanging construction method for the overhanging and downward-hanging type cast-in-place slab solves the problems that an existing overhanging and hanging type cast-in-place slab is slow in construction, and an all-round scaffold needs to be built, and has the advantage of being short in construction period.
本发明涉及一种用于悬挑并下挂式现浇板的吊挂施工方法，第一步：拼装模板胎架；第二步：将上、下层钢梁吊装到钢柱相应位置并安装完毕；第三步：将拼装好的模板胎架与下层钢梁固定在一起；第四步：吊索上设置有紧线扣，将吊索下端与模板胎架固定，将吊索上端与上层钢梁固定，并利用紧线扣初紧吊索；第五步：在模板胎架上铺设木方，木方上铺设模板；第六步：在模板上铺设结构钢筋并浇捣混凝土；第七步：待混凝土强度等级达到要求后，首先松掉紧线扣，然后拆卸模板胎架，接着拆卸木方和模板，最后拆卸吊索，至此一层悬挑并下挂式现浇板施工完成。本发明解决了目前悬挑并下挂式现浇板施工慢、需要搭建满堂脚手架的这些问题，具有施工周期短的优势。
