Thin-wall square box anti-floating structure and construction method thereof

Abstract

The invention provides a thin-wall square box anti-floating structure. The thin-wall square box anti-floating structure comprises a floor slab supporting framework, a formwork for pouring concrete is arranged on the floor slab supporting framework, a plurality of thin-wall square boxes are laid on the formwork, bottom plate rebars are further arranged at the bottoms of the thin-wall square boxes, anti-floating pressing ribs are arranged on the tops of the thin-wall square boxes, the anti-floatation pressing ribs on the two sides of the thin-wall square boxes are fixedly connected with the bottom plate rebars through first pulling connection parts, and the bottom plate rebars are fixedly connected with the floor slab supporting framework through second pulling connecting parts. By arranging the first pulling connection parts and the second pulling connection parts, the thin-wall square boxes are fastened to the formwork, the requirement for floating prevention of the thin-wall square boxes is met, and meanwhile, the construction efficiency of operators for punching operation and the operation for tying iron wires to the frame body is effectively improved.

Description

technical field [0001] The invention belongs to the technical field of building engineering, and its specialty is building structure and construction technology, in particular to an anti-floating structure of a thin-walled square box used in the construction process of a hollow floor and a construction method thereof. Background technique [0002] In the prior art, the hollow-core slab framework used for pouring hollow-core slabs includes formwork for concrete pouring, and a plurality of hollow thin-walled square boxes are spread on the formwork at equal intervals, and bottom steel bars are also arranged at the bottom of the thin-walled square boxes. The top is provided with upper row of steel bars. Usually, the four sides of each thin-walled square box are punched on the formwork, and steel wires are used to pass through the formwork to fix the upper layer of steel mesh to the frame support system under the bottom formwork. Due to the large length of the steel wire, the an...

AI Technical Summary

Problems solved by technology

[0003] In order to overcome the defects existing in the prior art, the object of the present invention is to provide a thin-walled square box anti-floating structure and its construction method, which solves the problem of relatively poor anti-floating effect in the prior art, the number of holes punched on the formwork, and the number of turnover times of the formwork. Low, high labor intensity of workers, low construction efficiency and construction speed
