Anti-floating construction method for metal square box cast-in-place concrete hollow floor slab
The invention relates to the field of buildings, in particular to a metal square box cast-in-place concrete hollow floor anti-floating construction method which comprises the steps that S1, lofting is conducted according to a construction drawing; s2, rib beam steel bars and bottom plate steel bars are bound, and pipelines are pre-buried; s3, bottom plate pouring is carried out, bottom plate concrete is compacted and flattened through vibration, surface finishing treatment is carried out after pouring is completed, and the upper surface of the bottom plate is subjected to chiseling treatment; s4, the square boxes are placed in the grids formed by the ribbed beams, surface layer steel bars and plate end supporting negative reinforcements are bound, and the square boxes are circumferentially limited through the plate end supporting negative reinforcements; and S5, concrete pouring is conducted on the floor slab, and the floor slab is poured to the preset elevation. The bottom plate concrete is firstly poured and formed, then the square box is fixed in an anti-floating mode, then the bottom plate concrete is poured to the preset elevation, the traditional mode that an iron wire penetrates through a metal box or a formwork is replaced with the layered pouring mode, the metal box does not need to be punched, the material cost is reduced, the labor efficiency is obviously improved, and the labor amount and the labor cost are reduced.
本发明涉及建筑领域，具体涉及一种金属方箱现浇混凝土空心楼板抗浮施工工法，步骤S1，根据施工图纸进行放样；步骤S2，绑扎肋梁钢筋及底板钢筋，并预埋管线；步骤S3，进行底板浇注，通过振捣使底板混凝土紧实平整，浇注完成后进行收面处理，并对其上表面进行凿毛处理；步骤S4，将方箱放入各肋梁所形成的方格内，绑扎面层钢筋和板端支撑负筋，通过板端支撑负筋对方箱进行周向限位；步骤S5，对楼板进行混凝土浇注，将楼板浇注至预设标高。底板混凝土先浇筑成型后进行方箱抗浮固定，然后浇注至预设标高，用以上分层浇筑的方式替代传统的铁丝穿过金属箱或者模板的方式，金属箱无需打孔，降低材料成本，明显提高劳动效率，降低用工量，降低人工成本。
