Construction method for large cavity hollow floor slab
The invention relates to a construction method for a large cavity hollow floor slab. The invention transfers the buoyancy generated by a box mold during pouring and vibrating to a formwork system through floor steel bars, box mold side rib beams, iron wires and formwork keels to form an anti-floating point. By setting the box mold as an inner mold that can replace a template to be erected, the filling and vibrating can be seen during concrete pouring, which can ensure the quality of pouring and vibrating. Through the anti-floating design, the box mold is fixed to prevent the box mold from floating and displacement during pouring and vibrating, thereby ensuring the quality of concrete pouring and vibrating. The construction method provided by the invention is especially suitable for the construction of large-cavity hollow floor slabs, and can solve the problems of inconvenience of large-cavity formwork and easy vibration leakage during concrete pouring to be unable to guarantee the quality.
本发明涉及一种大空腔空心楼板施工方法，本发明将箱模在浇筑、振捣时产生的浮力通过楼板上钢筋、箱模边肋梁、铁丝以及模板龙骨传递到模板体系，形成抗浮点。通过设置箱模作为内模，可以代替模板支设，在混凝土浇筑时填充以及振捣可视，能够保证浇筑以及振捣质量。通过抗浮点的设计，将箱模进行固定，能够防止箱模在浇筑以及振捣时的浮动以及位移，从而保证混凝土的浇筑以及振捣质量。本发明尤其适用于大空腔空心楼板的施工，能够解决大空腔支模不便、混凝土浇筑时容易漏振质量无法保证的问题。
