Abstract
The utility model discloses a cast-in-situ concrete hollow floorslab of a thin-wall box body, which comprises a closed box body and a mat reinforcement, wherein the upper portion and the lower portionof the box body are respectively provided with the mat reinforcement and a metal mesh, lower four corners of each box body are provided with cushion blocks, the upper portions of two adjacent box bodies are provided with an anti-floating steel rib, two rows of vertical multi-ribbed steel ribs are arranged between the two adjacent box bodies, each row of multi-ribbed steel ribs are attached on twosides of the box bodies, and two anti-floating iron wires are further vertically arranged between the two adjacent box bodies, and pouring concrete is filled between the box bodies and the mat reinforcement and on the mat reinforcement. The cast-in-situ concrete hollow floorslab of the thin-wall box body has the advantages of light sole weight, strong rigidity, excellent thermal-insulation and sound-proof property, low construction cost and strong practicality, lowers energy consumption, is economic and environment-friendly. Compared with a normal cast-in-situ concrete floorslab, the cast-in-situ concrete hollow floorslab reduces the use amount of steel ribs and concrete, is suitable for large-sized and medium-sized public buildings, domestic buildings and industrial buildings, and has excellent popularization values and wide development prospect.
Description
Technical field
The utility model relates to a kind of cast-in-place concrete hollow floor slab, refers in particular to a kind of thin-wall box-body cast-in-place concrete hollow floor slab.
Background technology
The thin-wall box-body cast-in-place concrete hollow floor slab technology is a great innovation of China's building structure field, it also is a kind of utility structure system that adapts to longspan structure, it has improved the mechanical property of total, can satisfy not only that the modern architecture span is big, the space is big, from heavy and light, can free demand at interval, also satisfied building sound insulation, vibration isolation, heat insulation, energy conservation and environment protection simultaneously.Have characteristics such as technology is simple, easy for installation, speed of application is fast, comprehensive cost is low.Thin-wall box-body cast-in-place concrete hollow floor slab can alleviate the floor deadweight effectively in using span scope, save steel, concrete amount, strengthens structural integrity.This structural system can reduce bright beam, post and body of wall, increases the floor clear height to greatest extent, obtains best usage space.But, because casing and reinforcement structure in the cassette ceiling are unreasonable, at present when cast-in-place concrete hollow floor slab, the upwards jacking force that flowing concrete produces during to the buoyancy of casing and vibrating head vibrated concrete, make casing produce come-up, this has brought hidden danger to construction quality.Developing a kind of thin-wall box-body cast-in-place concrete hollow floor slab that is easy to the science construction rational in infrastructure is necessary.
The utility model content
The technical problems to be solved in the utility model provides thin-wall box-body cast-in-place concrete hollow floor slab, this cassette ceiling utilizes the notion combined cast-in-situ floorslab construction characteristic of precast hollow slab, thin-walled cavity casing is imbedded in the concrete floor, the cast in situs moulding, make the solid concrete plate become hollowcore slab, can be used for big-and-middle-sized public building, civilian construction, industrial premises.
The technical problems to be solved in the utility model is realized by following scheme: thin-wall box-body cast-in-place concrete hollow floor slab, the casing, the steel mesh reinforcement that comprise one deck closed, it is characterized in that: the upper and lower of described casing respectively is provided with steel mesh reinforcement and gauze wire cloth, the below of every casing is provided with cushion block for four jiaos, the top of adjacent two casings is provided with an anti-floating reinforcing bar, prevent that to play casing from floating when the concreting, this acts in practice of construction obviously.The vertical close rib steel muscle of two rows is set between adjacent two casings, and the close rib steel muscle of every row all is close to the casing both sides, is used to play the effect of static housing position.Between adjacent two casings two anti-floating iron wires are set vertically also, between casing and the steel mesh reinforcement and the top concreting of all filling of steel mesh reinforcement.
The utility model also comprises following scheme: be the plane in the middle of the bottom surface of described casing, both sides are circular arc camber.Fixedly connected with gauze wire cloth with steel mesh reinforcement respectively in the two ends up and down of described close rib steel muscle.Fixedly connected with gauze wire cloth with the anti-floating reinforcing bar respectively in the two ends up and down of described two anti-floating iron wires.
The utility model has the advantages that: thin-wall box-body cast-in-place concrete hollow floor slab have from heavy and light, rigidity are strong, the heat preservation and soundproof performance is good, construction cost is low, practical, cut down the consumption of energy, plurality of advantages such as economic environmental protection.This thin-wall box-body cast-in-place concrete hollow floor slab when construction, the upwards jacking force problem that has produced when having solved flowing concrete to the buoyancy of casing and vibrating head vibrated concrete.Thin-wall box-body cast-in-place concrete hollow floor slab is compared with corresponding common cast-in-place concrete floor, and amount of reinforcement minimizing 20%, concrete amount reduce 27%.Because the reduction of floor deadweight, make the sectional dimension on post, wall and basis and arrangement of reinforcement, the corresponding minimizing of bright beam, its building integral gross weight reduces 20%.This thin-wall box-body cast-in-place concrete hollow floor slab uses at big-and-middle-sized public building, civilian construction, industrial premises, has not only obtained good economic benefit, has also improved the anti-seismic performance of structure, has excellent generalization values and vast potential for future development.
Description of drawings
