Embodiment 1

[0025] A construction method for a steel cage beamless hollow floor, comprising the following steps:

[0026] 1) Deepen the design and processing of the mesh of the box body: according to the plan layout of the hollow mold box in the design drawing, carry out the plane typesetting of the steel net box, the typesetting is carried out from the four sides to the middle, and the layout is set in the middle of the plane typesetting according to the actual size Non-standard plates and the size, specification and quantity of the steel cages are determined through the layout deepening design, and then the processing of the cage meshes is completed through rapid punching, pressing and stretching, positioning cutting, and fixed-length indentation processes using galvanized sheets as raw materials;

[0027] 2) Support the bottom formwork of the beamless hollow floor slab and the positioning of the spring line: the formwork is installed from one side, and the formwork installed later must ...

Embodiment 2

[0036] A construction method for a steel cage beamless hollow floor, comprising the following steps:

[0037] 1) Deepen the design and processing of the mesh of the box body: according to the plan layout of the hollow mold box in the design drawing, carry out the plane typesetting of the steel net box, the typesetting is carried out from the four sides to the middle, and the layout is set in the middle of the plane typesetting according to the actual size Non-standard plates and the size, specification and quantity of the steel cages are determined through the layout deepening design, and then the processing of the cage meshes is completed through rapid punching, pressing and stretching, positioning cutting, and fixed-length indentation processes using galvanized sheets as raw materials;

[0038] The compressive load on the top surface of the steel cage is 1000N, and the compressive load on the side is 800N. The mechanical wire boxes and pipelines embedded in the structure are ...

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...
