Construction process method of steel net cage beam-free hollow floor

Abstract

The invention discloses a construction process method of a steel net cage beam-free hollow floor, which comprises the following steps of 1) detailed design, processing of net sheets of a cage body; 2)erection of a beam-free hollow floor bottom die and positioning by snapping a line; 3) paving of a bottom anti-cracking steel wire gauze; 4) binding of a reinforcement sheet strip and dense rib beamsteel; 5) pre-embedded electromechanical wire box and pipeline: arranging the pre-embedded electromechanical wire box and pipeline on the reinforcement sheet strip or a dense rib beam, so as to prevent the floor from cracking or falling due to thin bottom; 6) field fabrication and installation in place of a steel net cage, anti-floating points setting and inspection; 7) binding of upper reinforcement of the beam-free hollow floor, acceptance of concealed work; 8) paving of concrete pouring shortcuts and preparation before pouring; and 9) concrete pouring and vibrating, as well as form-removingand maintenance of concrete. The steel net cage beam-free hollow floor greatly reduces the dead load of the structure, reduces the ratio of reinforcement, and saves the building cost of projects; furthermore, the construction and installation efficiency of the steel net cage beam-free hollow floor is high, and the construction cost is low.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to a construction method of a steel cage beamless hollow floor. Background technique [0002] How to make effective use of the internal space of the building, reduce the beam height and improve the space utilization rate while meeting the requirements of large-span structure is a major topic in the field of architectural design and construction. However, the conventional cement-made BDF hollow formwork is self-heavy, which greatly increases the structural self-weight load and increases the project cost; in addition, the conventional cement-made BDF hollow formwork is inefficient in site construction and installation, and the production process consumes a lot of natural resources. increase, and cause great pollution to energy consumption and the environment, and cannot meet the requirements of low-carbon, environmental protection, energy conservation, and emission reduc...
