Construction method facilitating guarantee of hollow floor structural size

Abstract

The invention relates to a construction method facilitating guarantee of hollow floor structural size. The construction method comprises the following steps that S1, a horizontal bottom formwork is laid; S2, a plurality of bottom layer steel bar cushion blocks are arranged on the bottom formwork, and a bottom steel bar layer is laid; S3, a plurality of second connecting pieces are used for connecting the bottom steel bar layer with the bottom formwork; S4, a plurality of placeholder box body cushion blocks are arranged on the bottom formwork, and a placeholder box body layer is laid; S5, an anti-floating steel bar layer is laid on the placeholder box body layer, and the anti-floating steel bar layer is supported by the placeholder box body layer; S6, a plurality of first connecting piecesare used for connecting anti-floating layer and the bottom formwork; S7, a plurality of top layer steel rib cushion blocks are arranged on the placeholder box body layer, and a top steel bar layer islaid; and S8, a plurality of third connecting pieces are used for connecting the top steel bar layer and the bottom steel bar layer. The anti-floating steel bar layer and the first connecting pieces are used for preventing placeholder box body tilting float after concrete slurry pouring, components in the floor are effectively fixed to guarantee the structure size of the floor to meet design sizerequirements and improve floor quality.

Description

technical field [0001] The invention belongs to the technical field of general building structures in buildings, and in particular relates to a construction method which is beneficial to ensure the structural size of hollow floor slabs. Background technique [0002] For frame structure buildings, the commonly used cast-in-place concrete slabs are ordinary solid slabs or ribbed solid slabs. After the force analysis, the floor is a load-bearing member, which undergoes slight bending deformation when it is stressed. The upper layer is a compression area, which bears pressure, and the lower layer is a tension area, which bears tension. In order to reduce the weight of the floor and save the amount of concrete, the middle layer of the floor can be reduced. Concrete, forming the upper and lower reinforced concrete layers and the structural form of reinforced concrete dense ribs required to connect the upper and lower layers so that they can bear the force and resist shear. The red...

Problems solved by technology

[0003] During construction, after the concrete grout is poured on the hollow floor slab, the lightweight space-occupied box is easy to float up and shift horizontally. There is the problem of occupying the box or the inclination of the steel bar, coupled with the influence of the strength of the pouring concrete slurry and the vibration of the tamping rod, the relative position of the structural parts of the floor slab deviates greatly from the design, and the construction quality is poor , affect the quality of building manufacturing and have potential safety hazards
