Reserved hole construction method for concrete pouring floor slab
The invention relates to the technical field of building construction, in particular to a reserved hole construction method for a concrete pouring floor. The two ends of the steel corrugated pipe are packaged through thin steel plates in a spot welding mode, the steel corrugated pipe is sleeved with a plurality of reinforcing steel bar hoops at intervals, the reinforcing steel bar hoops are fixed through connecting reinforcing steel bars to form a framework support, the steel corrugated pipe is placed at the position of a designed reserved hole, the framework support and the embedded bolts are fixed in a welding mode, and after concrete is poured, the steel corrugated pipe is fixed. The thin steel plate at the top of the steel corrugated pipe is taken down, then the steel corrugated pipe is pulled upwards till the steel corrugated pipe is completely taken out, and meanwhile a cover plate is laid on the reserved hole; the embedded bolts and the framework supports are welded, it is guaranteed that the steel corrugated pipe cannot move, the accuracy of the position of the reserved hole is guaranteed, the steel corrugated pipe can be pulled out after the thin steel plate on the top is taken down during later dismantling, destructive dismantling is not needed, the steel corrugated pipe can be recycled, the construction cost is reduced, concrete cannot be damaged, and the construction efficiency is improved. And the method can be widely applied to the construction field of large embedded parts on a construction site.
本发明涉及建筑施工技术领域，具体是一种混凝土浇筑楼板的预留洞施工方法。钢制波纹管的两端通过薄钢板点焊包封，钢制波纹管上间隔套设有若干个钢筋箍，钢筋箍之间通过连接钢筋固定形成骨架支撑，将钢制波纹管放至设计的预留洞位置，并将骨架支撑与预埋螺栓焊接固定，混凝土浇筑后，将钢制波纹管顶部的薄钢板取下，然后将钢制波纹管向上拉取直至完全取出，同时在预留洞上铺设盖板；通过预埋螺栓和骨架支撑相焊接，保证了钢制波纹管不会移位，确保了预留洞位置的准确性，后期拆除时将顶部的薄钢板取下后，将钢制波纹管拉出即可，不需要破坏性拆除，且钢制波纹管可以循环使用，施工造价成本降低，不会破坏混凝土，减少安全隐患，可以广泛应用于施工现场大型埋件的施工领域。
