Abstract
The utility model relates to a filling member for case-in-situ reinforcement concrete, particularly a prefabricated hollow pipe member. The prefabricated hollow pipe member comprises a hard hollow pipe and end plugs, wherein the hard hollow pip is sealed into a sealing inner chamber by the two end plugs, the hollow pipe presents rod-shaped or strip-shaped structure, the cross-section shape of the hollow pipe is a polygon which is combined by a rectangle or a square and two eudipleural bow shapes or a isosceles trapezoid, and the shape of each end plug is matched with the shape of the cross section of the hollow pipe. The prefabricated hollow pipe member of the utility model has the structure that a waist hoop and a positioning hook are arranged on a pipe body of the hollow pipe, and has the advantages of simple structure, light weight, rapid transportation and lift, and convenient construction. The pipe body of the hollow pipe is provided with the waist hoop and a vertical reinforcing rib so that the hollow pipe is used for filling materials of a case-in-situ concrete hollow floor with the non-loose-core hole technology. The utility model has the advantages of high strength and resistance, can reduce self weight of floor structure, improves floor performance, saves consumption of the concrete, and reduces engineering construction cost.
Description
One, technical field: the utility model relates to the noggin piece that a kind of cast-in-situ reinforced concrete is used, and particularly relates to a kind of precast hollow pipe component.
Two, background technology: in the present large-scale building construction process of construction, seldom used prefabricated hollow floor, because of its Heavy Weight, needed lifting, installation, use, transportation are all inconvenient, waste of manpower, material resources, financial resources.After using the on-the-spot installation of cast-in-place technology cassette ceiling instead, for alleviating floor weight, perhaps for reaching heat insulation preferably, soundproof effect, save the concrete consumption simultaneously, on-the-spot some permanent cores that often adopt, as paper tube, plastic pipe, metal bellows, what also have uses the cement fibre pipe, or the like as becoming pole.Because these materials are because each side is big as weight, construction is inconvenient, and perhaps the price height causes the cost height; Be exactly because of intensity difference, can't bear the effect of complicated pulling force, pressure, shearing etc., can not well come into operation, and some can overcome the hollow pipe component structure more complicated of above-mentioned shortcoming, manufacturing cost is higher, uneconomical practicality.Develop a kind of precast hollow pipe component of cast-in-place reinforced concrete filling of novel economy for this reason, just become a current building trade problem demanding prompt solution.
Three, utility model content:
Technical problem to be solved in the utility model:, design a kind of practical precast hollow pipe component simple in structure according to the situation of prior art building trade cast-in-situ concrete hollow pipe component structure more complicated.
The technical scheme that adopts: described precast hollow pipe component, contain hard hollow section and plug, two plugs seal into a closed inner chamber with the hard hollow section, hollow section is bar-shaped or the bar shape structure, its cross sectional shape is rectangle or square and two symmetrical arc or polygons that isosceles trapezoid is combined into, and plug shape and hollow section shape of cross section are complementary.
Described precast hollow pipe component, the plug that connects two hollow sections is as a whole, and the hollow section body is provided with 2, or 3, or 4, or 5 waist hoops, be provided with the outwardly directed hook that is used to locate in waist hoop top.
Described precast hollow pipe component is provided with vertical ribs at the hollow section body, and vertically ribs is fixedlyed connected with the waist hoop, and vertically the material of ribs is Cement fibre or FGC material, or is iron wire or steel band, and the material of waist hoop is an iron wire, or is steel band.
Positive beneficial effect:
1, the utility model precast hollow pipe component is provided with waist hoop and positioning hanger at the hollow section body, and is simple in structure, in light weight, and carrying, lifting are fast located easy construction.
2, by waist hoop and vertical ribs are set at the hollow section body, make it be used as the filler of the non-core-drawing pore-creating technology of hollow cast slab, have higher intensity and drag, can reduce the floor slab structure deadweight, improve the performance of floor, save the consumption of concrete, shorten the construction period, reduce the engineering construction cost.

Five, the specific embodiment:
Embodiment one: referring to Fig. 1, Fig. 2, Fig. 3, the precast hollow pipe component contains hard hollow section 1 and plug 4, hollow section 1 is bar-shaped or the bar shape structure, its cross sectional shape is rectangle or square and two polygons that symmetrical isosceles trapezoid is combined into, plug 4 shapes and hollow section 1 shape of cross section are complementary, two plugs 4 seal into a closed inner chamber with hard hollow section 1, are provided with the waist hoop 2 that has positioning hanger 3 at the body of hollow section 1.
Hollow section 1 body and plug 4 materials are Cement fibre or plant fiber polymerization thing (FGC) material, promptly add the material that special binding agent and glass fiber are made with a kind of material in sawdust, wheat straw, straw, the cornstalk etc.The hollow part of hollow section can partly or entirely be filled and be run foam, polyester, expanded perlite, rock wool, mineral wool or glass wool.
Embodiment two: referring to Fig. 4, Fig. 5, number in the figure is identical with embodiment one, represents meaning identical, does not repeat.Present embodiment precast hollow pipe component and embodiment one difference are that its cross sectional shape is rectangle or square and two symmetrical arc cydariform sections that are combined into.
Embodiment three, four: respectively referring to Fig. 1, Fig. 4, the precast hollow pipe component of this two embodiment, when hollow section is prefabricated, be respectively equipped with waling and horizontal waist hoop at the body of hollow section 1 and the two ends of hollow section, vertically ribs is fixedlyed connected with waist hoop 2, and the material of waling is Cement fibre or FGC material, or is iron wire or steel band, the material of waist hoop is an iron wire, or is steel band.Hollow section 1 body and plug 4 materials can be Cement fibre or plant fiber polymerization thing (FGC) material.
