Abstract
The invention relates to a fabricated concrete hollow floor structural system. The fabricated concrete hollow floor structural system is formed by means of stacking and assembling of a floor cast-in-situ layer and a floor pre-fabricated layer; a plurality of hollow structures are arranged in the floor cast-in-situ layer; each hollow structure is a hollow box or a light material body; slab top constructional steel bars are arranged in the floor cast-in-situ layer; pre-fabricated slab constructional steel bars are arranged in the floor pre-fabricated layer; the floor cast-in-situ layer is provided with a ribbed beam top reinforcement, ribbed beam bottom reinforcement, and ribbed beam stirrup, or the bottom of the ribbed beam bottom reinforcement is pre-embedded in the floor pre-fabricated layer; and the ribbed beam top reinforcement and the ribbed beam bottom reinforcement stretch to the side edge of the floor, and become the load-bearing bars lapped with the beam. The fabricated concrete hollow floor structural system has the advantages of being low in cost, being high in efficiency, saving materials, reducing self-weight, being relatively more reasonable in stress, being high in structural strength, and being high in quality.
Description
Technical field
The invention belongs to construction engineering technical field, and in particular to a kind of assembly concrete hollow floor structure system.
Background technology
Full cast-in-place concrete hollow building roof has to be saved construction material, mitigates high excellent of deadweight, good integrity, structural strength
Point.But full cast-in-place concrete hollow building roof needs to carry out substantial amounts of, rolls over template and kit formula supporting system, quantities
Greatly, complex operation, generally requires special wooden model skilled industrial worker, many high costs of template, long construction period, after placing concrete,
Form removal is time-consuming to take a lot of work.Meanwhile, cast-in-place concrete hollow building roof lower flange thickness is relatively thin, and during casting concrete, lower flange is easy
There are the leakiness problems such as bubble, cavity, affect superstructure quality.Additionally, during concreting, empty van is known from experience by larger floating
Power, floats upwards, it is therefore desirable to cushion block positioning is added between reinforcing bar and empty van body, the thickness of top flange is just can guarantee that, therefore,
Ensure that hollow building cover quality difficulty is big.
The content of the invention
The present invention to be solved determine technical problem be：Above-mentioned prior art is solved the problems, such as, and a kind of assembling is provided
Formula concrete hollow building roof structural system, saves, form removal and kit formula supporting system, greatly reduces workload, drops
Low construction cost, there is provided efficiency of construction, saves construction material, significantly mitigates deadweight, and stress is more reasonable, and structural strength is high, quality
It is good.
The technical solution used in the present invention is：A kind of assembly concrete hollow floor structure system, by superstructure in-situ layer
It is assembled with superstructure preformed layer overlapping, multiple hollow-core constructions is provided with superstructure in-situ layer.
In above-mentioned technical proposal, described superstructure preformed layer equally splits the prefabricated panel of width by overlapping steel by polylith
Muscle is connected and composed.
In above-mentioned technical proposal, described hollow-core construction is hollow box or light material body.
In above-mentioned technical proposal, described hollow box is GBF hollow boxs, and the light material body is foams.
In above-mentioned technical proposal, top of the plate cage structure reinforcing bar is provided with the superstructure in-situ layer, in the superstructure preformed layer
It is provided with precoated plate distributing bar.
In above-mentioned technical proposal, between the hollow-core construction and hollow-core construction of the superstructure in-situ layer, girt strip top is provided with
Arrangement of reinforcement, girt strip bottom arrangement of reinforcement and rib beam hoop reinforcement.
In above-mentioned technical proposal, in the superstructure preformed layer position corresponding with rib beam hoop reinforcement girt strip bottom stirrup is provided with.
In above-mentioned technical proposal, described girt strip top rebars and girt strip bottom arrangement of reinforcement stretch out superstructure side, become and beam
The steel bar stress of overlap joint.
Advantage and beneficial effect：
1st, building deadweight is mitigated, because floor deadweight accounts for the 30-40% of building deadweight, therefore, floor weight reduction supports building
The section of the beam, post and basis of plate reduces, weight reduction；
2nd, load effect is reduced, deadweight reduces then vertical load and reduces；Deadweight reduces, and seismic force reduces；
3rd, load effect is little, reduces steel area size and arrangement of reinforcement；Steel are saved, it is energy-saving；
4th, building cost is low；
5th, construction workload greatly reduces, and saves a large amount of templates and supporting support tool, and difficulty of construction is reduced, and construction period subtracts
Short, working performance is greatly improved；
6th, good looking appearance, it is not necessary to furred ceiling, heat preservation energy-saving, soundproof effect is good.
