Open-web floor system steel net cage mould box construction method

Abstract

The invention provides an open-web floor system steel net cage mould box construction method which comprises the following steps of construction preparation, folding welding, inspection and acceptance, mounting of a floor system support frame and floor templates, mounting of framed girders and ribbed beam steel bars, correction of beam straight degree, arrangement of a steel net cage mould box, tying of beam steel bars, pouring of concrete to the mould box and engineering quality testing. According to the construction method, the use level of the steel bars is decreased, and the steel bar use level is saved by approximately one third compared with an ordinary reinforced concrete solid floor; and the structural framed girders, the ribbed beam steel bars and the plate bottoms are all in the same horizontal plane, the plates are conveniently laid, formwork supporting construction difficulty is lowered, formwork supporting is accelerated, template consumption is extremely low, the number of turnover times of the templates is decreased, and the construction cost is lowered.

Description

technical field [0001] The invention relates to the technical field of building engineering construction, in particular to a construction method of a steel net box mold box for an empty stomach floor. Background technique [0002] The mold box in the traditional cast-in-place reinforced concrete hollow slab has defects such as vertical anti-floating, horizontal displacement, and poor compatibility, which require isolation and pads, damage, heavy weight, cumbersome construction, and difficult transportation, etc., to achieve buoyancy when pouring concrete And the displacement is uncontrollable, the dense state cannot be directly observed when pouring the bottom concrete, the generation of microcracks in the floor cannot be effectively suppressed, and the appearance quality of the bottom of the concrete pouring cannot be guaranteed. Contents of the invention [0003] In order to solve the above-mentioned technical problems, the present invention provides a method for constru...

Problems solved by technology

[0002] The mold box in the traditional cast-in-place reinforced concrete hollow slab has defects such as vertical anti-floating, horizontal displacement, and poor compatibility, which require isolation and pads, damage, heavy weight, cumbersome construction, and difficult transportation, etc., to achieve buoyancy when pouring concrete And the displacement is uncontrollable. When pouring the concrete at the bottom, its dense state cannot be directly observed, and the generation of micro-cracks in the floor cannot be effectively suppressed, and the appearance quality of the bottom of the concrete pouring cannot be guaranteed.
