Abstract

Disclosed is a mould for concrete flat roof contraction joint leakage-proof construction, which adopts the scheme that a T-shaped moulding bed and two plastic film layers for covering both sides and the bottom face of a steel plate internal mold are arranged; the T-shaped moulding bed comprises a square wood pattern and a rectangular wood pattern symmetrically fixed on the bottom face, the square wood pattern and the rectangular wood pattern have the equal length, and the thickness of the steel plate internal mold is 0.5mm, defects of easy ageing and nondurable waterproofing material, high cost of manufacture, maintenance demand after a period of time and unavailable water storage are overcome in the prior art, and the utility model is applied to contraction joint waterproof and leak-proof layers of various concrete flat-topped houses.

Description

Concrete flat roof shrinkage joint leak-proof construction mould

Technical field

The utility model relates to a kind of concrete flat roof shrinkage joint leak-proof construction mould.

Background technology

At present, the leakage cause of concrete flat roof shrinkage joint and flat roof comprises that the shrinkage joint is different because of the coefficient of expansion that the various materials of making the concrete flat roof expand with heat and contract with cold, and produces be full of cracks, and roofing is heated inhomogeneous and is heated and successively produces be full of cracks; For the waterproof leakproof, the constructor adopts various waterproofing materials manufacturings and maintenance roofing, but various waterproofing materials has a common shortcoming: easily aging, not durable, the cost height needs repairing in use for some time, can not retaining.

Summary of the invention

At above-mentioned situation, it is the waterproof application of anti-leakage layers at external mold and concrete flat roof shrinkage joint with the thin mould of plastics that the utility model provides a kind of, and it is simple to make concrete flat roof expanded joint structure, the concrete flat roof shrinkage joint leak-proof construction mould that cost is low.

For achieving the above object, a kind of concrete flat roof shrinkage joint leak-proof construction mould comprises T shape loose tool and wraps up two layers of plastic sheeting of steel plate internal mold both sides and bottom surface; Described T shape loose tool comprises fixedly rectangle wooden model of square wooden model bottom surface symmetry.

In order to realize result optimizing, improve, improve combination property of the present utility model, further step is:

The thickness of described steel plate internal mold is 0.5mm.

The utility model adopts two layers of plastic sheeting of T shape loose tool and parcel steel plate internal mold both sides and bottom surface; T shape loose tool comprises fixedly rectangle wooden model of square wooden model bottom surface symmetry, the equal in length of square wooden model and rectangle wooden model, and the thickness of steel plate internal mold is the scheme of 0.5mm, it is easily aging, not durable to have overcome in the prior art waterproofing materials, the cost height, need repairing defective that can not retaining over time.

The beneficial effect that the utility model is produced compared to existing technology:

1, make shrinkage joint, concrete flat-top room waterproof application of anti-leakage layers with two layers of plastic sheeting, and the earth that on concrete flat-top room, tiles, cover plastic sheeting, play the maintenance effect, plastic sheeting is not aging for a long time, does not damage; Tiling earth plays heat-blocking action on the concrete flat-top room, and the plantation flowers and plants.

2, simple in structure, easily manufactured, cost is low.

3, mould, concrete flat roof and shrinkage joint need not keeped in repair.

4, mould, concrete flat roof and shrinkage joint long service life.

The utility model is applicable to makes various concrete flat roofs shrinkage joint waterproof application of anti-leakage layers.

Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.

The specific embodiment

By accompanying drawing Fig. 1, Fig. 2, Fig. 3, Fig. 4, shown in Figure 5, a kind of concrete flat roof shrinkage joint leak-proof construction mould comprises T shape loose tool 1 and wraps up two layers of plastic sheeting 5 of steel plate internal mold 4 both sides and bottom surface; Described T shape loose tool 1 comprises fixedly rectangle wooden model 3 of square wooden model 2 bottom surfaces symmetry, the equal in length of square wooden model 2 and rectangle wooden model 3, and the thickness of steel plate internal mold 4 is 0.5mm; When making the concrete flat roof; earlier at the good and sound hollowcore slab of roofing; after tying seam; on hollowcore slab, spread the thick sand of 35mm; at sand upper berth one deck malthoid; make separation layer; on separation layer, lay T shape loose tool 1; the square wooden model 2 of T shape loose tool 1 is following; rectangle wooden model 3 is last; be laid to wide 2 meters; the long horizontal fritter that is no more than 10 meters parallel rule; facade fritter with wall; laying sandstone concrete and jolt ramming are floating in fritter; take out T shape loose tool 1; stay the T shape dead slot of making by T shape loose tool 1 size this moment on the concrete roof; vertical storing and fixing steel plate internal mold 4 on the center line of T shape dead slot with two layers of plastic sheeting, 5 parcel both sides and bottom surface; the opening of plastic sheeting 5 is made progress; cast contains the step surface of husky concrete to T shape dead slot; the outer layer plastic film 5 that is wrapped in steel plate internal mold 4 is tiled in containing on the husky concrete of steel plate internal mold 4 both sides; then cast contains husky concrete on the outer layer plastic film 5 of tiling; until concordant with the sandstone concrete plane; again inner plastic film 5 is tiled in and contains on the husky concrete; extract steel plate internal mold 4 out; two layers of plastic sheeting 5 with contain husky concrete binding; form two layers of V-arrangement plastic sheeting 5 seam, manufacture the shrinkage joint application of anti-leakage layers, plastic sheeting 5 is in that contain can be anti-aging under the cement-soil; therefore on the roof, shrinkage joint that plastic sheeting 5 is made, lay earth not only to 5 protections of two layers of V-arrangement plastic sheeting but also can save the fabricating cost of concrete flat roof isolation layer, kind of the grass of can also growing flower.
