Abstract
The utility model relates to a preset hollow hard thin-wall member type cast-in-place reinforced concrete hollow slab, which is composed of a steel reinforcement, concrete, and a hollow hard thin-wall member preset in the steel reinforcement, wherein, the hollow hard thin-wall member is positioned by a fixing and positioning member; the hollow hard thin-wall member can be a hollow hard thin-wall cylinder or a hollow hard thin-wall box; the cross-sectional shape of the hollow hard thin-wall member can be circular, or square or other shaped, and the material is water insoluble hard material. The utility model has the advantages of simple and convenient construction, high safety, wide applicability, effectively ensured design requirement, material saving, low cost, etc.
Description
The utility model belongs to a kind of cast-in-situ reinforcing steel bar concrete hollow slab, mainly be applicable to the floor of industry and civil building, also can be applicable in the cast-in-situ reinforcing steel bar concrete hollow slabs such as hollow bridges, hollow road surface, basic hollow base plate, basic hollow pile, hollow stair, hollow step, hollow shear wall slab.
At present, cast-in-place building (roofing, basis) plate (containing prestressed slab) adopts solid slab, solid slab concrete consumption is many, from great, amount of reinforcement is big, span is little, cap is big, has increased post and basic load simultaneously, and is very uneconomical.Cast-in-place rib ellbeam plate body exposes a lot of primary and secondary beams or little girt strip at the bottom of tying up to plate, and is not attractive in appearance, needs furred ceiling, can not carry out large bay and separate, and is unfavorable for the installation of water power air conditioning piping.Beam has reduced headway.Because of top board is very thin, sound insulation is poor, so the beam slab system is uneconomical, and function of use is poor.Precast hollow slab has and is suitable for little, the easy crack of span, easy to leak, structural integrity is poor, can only be that one-way slabs is used, and earthquake resisting performance is poor, the distortion that causes of factor such as basic differential settlement irresistibly, be used for multilayer, little span building more, can not be used for highrise building.
In the patent documentation of notification number CN2228503Y, disclose a kind of cast-in-place hollow slab with permanent fetal membrane, this In-situ cast concrete board is " containing hollow fetal membrane in the In-situ cast concrete board inside of making ", and this cast-in-place hollow slab with permanent loose tool has following shortcoming:
1, cast-in-place difficult forming, unreasonable structure.Described in prospectus and accompanying drawing, hollow mould is when the concrete moulding by casting, and loose tool makes concrete upper strata attenuate because of cast vibration concrete slurry causes the loose tool come-up, and concrete plate upper strata is a pressure zone, and structure tension performance is unreasonable.
2, cavity is not sealed at the hollow mould two ends, and the concrete slurry easily enters hollow mould and makes the decline of hollowcore slab hollow rate during the concrete moulding.
3, hollow mould is as described in prospectus and the accompanying drawing, and cross sectional shape is trapezoidal, square, circular or other shape.Arranged direction is the unidirectional cloth loose tool, and the concrete hollow board of formation is an one-way slabs, is single load bearing under construction, can not make two-way slab and use.Can not satisfy the needs of the multidirectional stressed form of structure of building.
4, because disclosed hollowcore slab belongs to the Cast-in-place concrete member, adopt hardboard, rigid foam or potter's clay etc. to make hollow mould, the former two has reduced the fireproof performance of hollowcore slab building, latter's potter's clay potter's clay pug when concrete formation is entered in the concrete by the softening back of bubble potter's clay, the intensity of concrete reduces significantly, hardboard bubble after-tack loose tool easily subsides, and increases the concrete amount.
The purpose of this utility model is to overcome the prior art shortcoming, provides a kind of construction simple and easy, and applicability is wide, stress performance is reasonable, quality safety is reliable, and is rational in infrastructure, and can effectively guarantee the cavity hard thin-wall members formula that the presets cast-in-situ reinforcing steel bar concrete hollow slab that design strength requires.
The utility model presets cavity hard thin-wall members formula cast-in-situ reinforcing steel bar concrete hollow slab, is made up of reinforcing bar, concrete, the cavity hard thin-wall members that is preset in the reinforcing bar, and described cavity thin-wall member is by stationary positioned member location.
Below in conjunction with description of drawings the utility model is elaborated.

Fig. 7 is the schematic diagram of expression cavity hard thin-wall members stationary positioned form embodiment two.
Fig. 8 can make things convenient for the pre-buried hollowcore slab finished product user mode schematic diagram of water, electric line and airduct for expression cavity hard thin-wall members.
As Figure 1-3, the utility model is made up of reinforcing bar 1, concrete 2, the cavity hard thin-wall members 3 that is preset in the reinforcing bar, and before the concrete cast, cast cavity hard thin-wall members 3 is by stationary positioned member 4 location.Described cavity hard thin-wall members can be cavity hard thin-wall tube or cavity hard thin-wall box, and its cross sectional shape can be circular, square or other is special-shaped, as shown in Figure 4, is orthohexagonal.The pipe of described cavity hard thin-wall members (box) wall is water-fast hard material, can be Cement fibre stereoplasm tube (box) or organic/inorganic composite material horniness thin-walled tube (box) or steel pipe (box) or plastic pipe (box) or hard paper tube (box).Described cavity hard thin-wall members can be the enclosed cavity combined member of single sealed hollow member or the formation of a plurality of open type hollow unit combination rear enclosed both ends open, as shown in Figure 5.Unidirectional being arranged in parallel of cavity axis of described cavity hard thin-wall tube, or cross arrangement in length and breadth, or multidirectional arrangement, as shown in Figure 1, 2.The embodiment that Fig. 1-3 provides, cavity hard thin-wall members all are arranged on the concrete hollow board middle part, fit up cabling in order to satisfy, and some specific (special) requirements, and the cavity hard thin-wall members also can be arranged on top or bottom or the portion or portion position on the upper side on the lower side of hollowcore slab.
Fig. 6, Fig. 7 have provided the stationary positioned embodiment of cavity hard thin-wall members, shown in Fig. 6,7, the stationary positioned member 4 of cavity hard thin-wall members can be Y type bearing and bearing and closes and buckle 4-1,4-2, or be " n " shape iron wire 4-3, or be the reinforcing bar 4-4 that bears down on one, fastening iron wire 4-5 and locating piece 4-6.Also can adopt other members and method control cavity hard thin-wall members to pour into a mould buoyancy produces in the process of vibrating fluctuating or moving horizontally, to avoid cavity to form irregular or not meet designing requirement, to guarantee hollowcore slab intensity and quality at concrete.For example adopt locating bar 4-7 control mobile, realize the location, before the concrete cast, be inserted between the cavity hard thin-wall members, not dried preceding taking-up the after the concrete cast.
The utility model presets cavity hard thin-wall members formula cast-in-situ reinforcing steel bar concrete hollow slab, requires to be formed with beam porous plate, no beam porous plate, no post according to different designs and emits porous plate, secretly beam porous plate, porous foundation slab, hollow pile, stair, step, shear wall or above combination.Have following advantage:
1, easy construction, safety, reliable, quick, construction cost is low.
2, applicability is wide, is applicable to building, road surface, the basis of various spans and various loads.Multilayer and highrise building floor as large span, big load, large space have more superiority.
3, can effectively guarantee designing requirement and requirement of strength.
4, save material, reduce comprehensive cost, the one, the steel bar concrete cost reduces; The 2nd, the template loss reduces; The 3rd, can utilize the pre-buried water of cavity hard thin-wall members, electric line, airduct (as shown in Figure 8), can save water, electric line, airduct sleeve pipe, save outer making up and use.
