Abstract

An insulating light floor slab is composed of external concrete layer, reinforcing bars, wood blocks, cennecting bars, core layer and plastic cloth. Its advantages include light weight and high thermal and audio-insulation.

Description

A kind of insulating light floor slab and preparation method thereof

The invention belongs to constructional materials, a kind of specifically insulating light floor slab.

At present the domestic floor that is used for construction work generally is a concrete floor, because its material mainly is: and cement, sand, stone, so, no matter be real core concrete plate, or hollow core slab, it is big that it is not only weight, but also do not have the performance of insulation, sound insulation.Chinese patent literature discloses " multifunctional light gives system floor and preparation method thereof " (1124313A), though it is a kind of novel preferably precast floor slab, but it remains and has adopted traditional core mould construction, the facility that this arts demand is a large amount of, and only limit to produce in factory, in addition, its employed material also all is mineral resources, and these resources are non-renewable.

The objective of the invention is according to above-described problem, a kind of insulating light floor slab that is used for building be provided, with and preparation method.

Realization of the present invention is finished by following technical scheme:

The present invention mainly is made of extexine (1), reinforcing bar (2), sandwich layer (3), Polypropylence Sheet (4) and wooden unit (5) and reinforcing bar (6).Described extexine (1) is meant ordinary concrete, special concrete or cement mortar.Reinforcing bar (2) is embedded in concrete centre.Described sandwich layer (3) is made up of heat insulating material, as: light heat insulation materials such as stalk, shrub branch and particle thereof, polystyrene foam plate, perlite, pumice in lumps, aerating concrete piece, slag, flyash, vermiculite, haydite, cinder concrete are formed.In order to reach better heat insulation effect, in the outer wrap of sandwich layer (3) one deck Polypropylence Sheet (4) (also plastic bag or malthoid).Be drilled with aperture in the middle of the wooden unit (5), the centre that it is evenly distributed in sandwich layer plays a part to support and power transmission.Connect muscle (6) and be through the centre of wooden unit, and be anchored in the concrete on two top layers.

Its preparation method has two kinds:

1, prefabricated: as promptly at first the reinforcing bar of making to be put on the platform of frame, with the concrete casting one deck for preparing, will connect muscle simultaneously and penetrate in the wooden unit, and be fixed on uniformly in this layer concrete, after with sandwich layer (3) be placed on the inside, in order to reach better heat insulation effect, sandwich layer is wrapped up a layer concrete above watering again at last with Polypropylence Sheet, simultaneously the sandwich layer and the slit of frame are all around filled up, and suitably made firm by ramming, at last that the surface is floating, maintenance forms.

2, field fabrication: promptly at first the reinforcing bar of making is put among the template, and pipelines such as electric wire are fixed on above the reinforcing bar,, will connect muscle simultaneously and penetrate in the wooden unit the concrete casting one deck for preparing, and be fixed on uniformly in this layer concrete, after sandwich layer is placed on above, in order to reach better heat insulation effect, sandwich layer is wrapped up with Polypropylence Sheet, a layer concrete above watering again at last, and shaken and smash, at last that the surface is floating, maintenance forms.

Advantage of the present invention is to utilize stalk etc. as sandwich layer,, make the floor middle part become the space of light material combination, thereby solved the problem of " cold bridge " as bilevel force-transmitting pole with wooden unit, reached the purpose of insulation, sound insulation, simultaneously also can be widely as wall body construction.

Below in conjunction with accompanying drawing by embodiment to feature of the present invention, and other correlated characteristic is described in further detail:

Embodiment 1:

Shown in accompanying drawing 1,2, the present invention is made of extexine (1), reinforcing bar (2), sandwich layer (3), Polypropylence Sheet (4) and wooden unit (5) and reinforcing bar (6).Extexine (1) is meant ordinary concrete, special concrete or cement mortar, and its thickness is between 10mm-50mm.Reinforcing bar (2) is embedded in concrete centre, or the load born little when the concrete span of slab hour, reinforcing bar (2) is gauze wire cloth also.Sandwich layer (3) is made up of the particle of stalk, shrub branch or these two kinds of materials, certainly also formed the same wooden unit of its thickness by light heat insulation materials such as polystyrene foam plate, perlite, pumice in lumps, aerating concrete piece, slag, vermiculite, haydites.In order to reach better heat insulation effect, in the outer wrap of sandwich layer (3) one deck Polypropylence Sheet (4) (also plastic bag).Wooden unit (5) is evenly distributed in the middle of the sandwich layer, play a part to support and power transmission, wooden unit is square, also short circle standing tree, and be drilled with aperture in the middle, the aperture is with connecting muscle, and its diameter is between φ 20mm-φ 100mm, height is between 30mm-200mm, and the distance between wooden unit and the wooden unit is generally between the 50mm-300mm, this is the same with quantity with the diameter of the muscle of being advocated in the concrete plate, determined that by its span and the load that bears this is that technician of the same trade is to understand, just repeats no more here, in addition, because it is a stressed member, thus preferably soak or the brushing anticorrisive agent, as pitch etc.Connect the centre that muscle (6) is through wooden unit, its two ends are stretched into and are anchored in the concrete on two top layers, and its diameter is between φ 1mm-φ 25mm.Described stalk is meant: Sunflower Stalk, sorghum stalk, cornstalk, hemp stalk, wheat straw, straw, reed etc., the shrub branch is meant: salix monogolica, red building, caragana microphylla, branch etc., also the particle of above-mentioned these materials or pipe nipple are formed.These core materials mainly have been filling effects, so, but also diffusing shape light heat insulation materials such as filled polystyrene cystosepiment, perlite, pumice in lumps, aerating concrete piece, slag, vermiculite, haydite certainly, or its goods and concrete class.

The enforcement of present embodiment is: at first reinforcing bar is put into mould, thick No. 200 concretes of one deck of pouring 30mm, the wooden unit that will be installed with φ 6mm reinforcing bar simultaneously is fixed therein, and the wooden unit diameter is φ 60mm, high 80mm, the spacing of two direction equates, the Wei @150mm (wooden unit soaked with pitch), then Sunflower Stalk is put between the wooden unit, with till filling up wooden unit gap and wooden unit and filling and leading up, bedding one deck Polypropylence Sheet waters No. 200 concretes of the thick one deck of 30mm at last more thereon, simultaneously the slit, surrounding is filled up.

Embodiment 2:

As shown in Figure 3, except that the technology identical with embodiment 1, difference is that first cement, slag (a) with 1: 6 fills up the slit, surrounding, back with (b) behind 1: 10 cement, saw foam and the water mix, be put on the pocket on sandwich layer stalk surface, floating with the stalk end face, and cancelled Polypropylence Sheet, upper epidermis is to have smeared thick 1: 3 cement mortar of one deck of 25mm.

Embodiment 3:

As shown in Figure 4, except that the technology identical with embodiment 1, difference is that a peripheral frame has been watered on four limits on the bottom concrete earlier, its highly same wooden unit, thickness is 20mm, material is No. 75 cinder concretes (c), and sandwich layer is by behind saw foam and the water mix, inserts between frame and the wooden unit, make real simultaneously, fill and lead up, and set up the steel mesh reinforcement of φ 4mm in the concrete on upper strata, its two-way spacing equates, the Wei @300mm.

Embodiment 4:

Except that the technology identical with embodiment 3, difference is that sandwich layer is made up of perlite and water mix, and has cancelled Polypropylence Sheet.

Embodiment 5:

Except that the technology identical with embodiment 3, difference is that sandwich layer is a slag of doing the shop.
