Construction method of post-cast strip floor slab with independent support

Abstract

The invention discloses a construction method of a post-cast strip floor slab with an independent support. The construction method aims at overcoming the technical defects of high construction cost, long formwork service cycle and the like. The construction method comprises the steps that a bottom formwork vertical supporting system is arranged; a group of vertical supporting PVC pipes are arranged at the connecting end of a floor slab and a post-cast strip; the upper ends of the PVC pipes communicate with the floor slab pouring area; concrete is poured into the floor slab, and the PVC pipes are filled with concrete; concrete curing is completed, and then the vertical supporting system is removed; the connection end of the floor slab and the post-cast strip after concrete pouring is supported by concrete stand columns in the vertical supporting PVC pipes; a post-cast strip pouring formwork is built again, and concrete of the post-cast strip is poured; and after concrete curing of the post-cast strip is completed, all formworks, the PVC pipes and the concrete in the PVC pipes are removed. The construction method has the beneficial effects that the service cycles of the formworks and supporting rods thereof are shortened, and the structural quality is ensured; and the cost is saved by 20% or above.

Description

technical field [0001] The invention relates to the field of building construction, in particular to a construction method with independently supported post-cast belt floor slabs. Background technique [0002] Due to the long interval between concrete pouring between the floor slab and the post-cast zone, there are currently two ways to support the formwork for the floor slab and the post-cast zone concrete pouring. To reduce the cost of formwork use, remove the formwork after the pouring and maintenance of the floor slab and before the pouring of the post-casting belt. When removing the formwork, the joint between the floor and the post-casting belt (that is, the cantilever end of the floor) is re-supported (returned) , but because the re-support (returning) is not timely or the re-supporting (returning) cannot meet the stress requirements, it is difficult to meet the structural force requirements of the connection between the floor and the post-casting belt (ie, the cantil...
