Cast-in-place concrete hollow floor structure and construction method thereof
The invention relates to the technical field of hollow floor systems, in particular to a cast-in-place concrete hollow floor system structure and a construction method thereof.The cast-in-place concrete hollow floor system structure comprises a formwork, a polystyrene core mold, bottom-layer steel bars, upper-layer steel bars, lower cushion blocks and upper cushion blocks, the bottom-layer steel bars and the upper-layer steel bars are arranged in parallel up and down, and the bottom-layer steel bars are arranged at the upper end of the formwork; the lower cushion blocks are arranged at the upper ends of the bottom-layer steel bars and are bound with the bottom-layer steel bars through iron wires I; the upper cushion block is arranged at the lower end of the upper-layer steel bar and firmly bound with the upper-layer steel bar through the iron wire I. The polystyrene core mold is arranged between the upper cushion block and the lower cushion block. A preformed hole is formed in the center of the polystyrene core mold, an iron wire II penetrates through the preformed hole, and the two ends of the iron wire II are connected with the mold plate and the upper-layer steel bar respectively and are tensioned; through holes are formed in the outer sides of the periphery of the polystyrene core mold on the mold plate, and iron wires II are connected between the through holes and the upper-layer steel bars. The hollow floor is easy to manufacture, the quality defect problem of the hollow floor is solved, manpower input is reduced, and the construction period is shortened.
本发明涉及空心楼盖技术领域，更具体而言，涉及一种现浇混凝土空心楼盖结构及其施工方法，包括模板、聚苯乙烯芯模、底层钢筋、上层钢筋、下垫块和上垫块，底层钢筋与上层钢筋上下平行设置，底层钢筋设置在模板上端，下垫块设置在底层钢筋上端并通过铁丝Ⅰ与底层钢筋绑扎；上垫块设置在上层钢筋下端并通过铁丝Ⅰ与上层钢筋绑扎牢固，聚苯乙烯芯模设置在上垫块与下垫块之间；聚苯乙烯芯模中心设置有预留孔，预留孔中贯穿有铁丝Ⅱ，铁丝Ⅱ的两端分别连接模板、上层钢筋并拉紧；模板上位于聚苯乙烯芯模的四周外侧均设置有通孔，通孔与上层钢筋之间连接有铁丝Ⅱ。本发明制作简单，消除空心楼盖的质量缺陷问题，减少了人力投入，缩短了工期。
