Construction method capable of accurately controlling thickness of concrete cast-in-place floor slab
The invention relates to a construction method capable of accurately controlling the thickness of a concrete cast-in-place floor slab. The construction method comprises the following steps of: carrying out internal bent support erection on a pouring floor to be constructed, and carrying out internal bent support elevator lofting rechecking and correction through measurement calculation; arrangingfloor steel bars on a beam plate formwork, binding the steel bars, and fixedly arranging a control block; pouring concrete, and determining the concrete pouring thickness according to the height of the control block in the concrete pouring process; inserting an adjustable floor slab thickness control steel chisel into the poured concrete to adjust the paving thickness of the concrete; after pouring is finished, using a darby for scraping and leveling by referring to a concrete prefabricated block, and finishing concrete pouring; and curing concrete after range and elevator rechecking is finished. The construction method is easy to operate, applicable, and the problem that quality hidden dangers are caused by inaccurate floor slab thickness control is solved. According to the construction method, fine control is carried out before, during and after concrete floor slab pouring before preliminary solidification of concrete, and it is ensured that the thickness flatness of the floor slab meets specification and design requirements through three way action.
本发明涉及一种精确控制混凝土现浇楼板厚度施工工法，包括以下步骤：对待施工浇注楼板进行内排架支撑搭设，通过测量计算对内排架支撑标高放样复核和修正；在梁板模板上布设楼板钢筋，对钢筋进行绑扎固定布置控制块；浇注混凝土，混凝土浇注过程中依据控制块高度确定混凝土浇注厚度；使用调节楼板厚度控制钢钎插入浇注的混凝土中调节混凝土的铺注厚度；浇注完成后使用刮尺参照砼预制块刮平收光，砼浇筑完成；在极差和标高复测完毕后对混凝土养护。本发明施工工法操作简单适用，避免了楼板厚度控制不精确造成质量隐患等问题。该工法在混凝土楼板浇筑前、浇筑过程中、浇筑后砼初凝前均进行了精细化把控，三管齐下，保证了楼板厚度平整度满足规范和设计要求。
