Abstract

The utility model relates to a light weight roof plate, which is characterized in that the utility model is composed of an upper and a lower plastic foam layers, a steel wire net layer arranged between the plastic foam layers, and a surface glass steel composite layer. The utility model has light self-weight, the strength of plate material can be raised by the steel wire net layer in a plate, the breakage-proof effect is better, the waterproof performance of the plate material is enhanced by the glass steel composite layer of the upper surface, and the heat-insulating and the shockproof effects of the utility model are also ideal. The utility model has the low production cost, can reduce the engineering cost and the construction difficulty, and is a generation changing product of the existing roof plates.

Description

Light wt. roofing slab

The utility model relates to the used light weight board in a kind of building roof.

The used shingle of common fixed buildings is generally cement pre-fabricated panel, and the big thing of concrete prefabricated plate body is heavy, the cost of production height, and difficulty of construction is big, and it is heat insulation, waterproof and shockproof effect are all undesirable.The used shingle of simple building then mostly is sheet asbestos or glass plate, and the shortcoming of this class sheet material is to use the life-span short, and intensity is low, cracky, and effect of heat insulation is more undesirable, and its deadweight that kicks the beam makes its windproof poor performance.

At the problem of above-mentioned existence, the utility model proposes a kind of novel roof precast plate of, long service life good from heavy and light, intensity height, insulating water-proof shockproof properties.

The technical solution of the utility model is as follows:

The utility model is a stratiform structure, and clamping has a steel screen layer between upper and lower plastic foam layer, and one deck glass fiber reinforced plastic composite bed is arranged above the above-mentioned last plastic foam layer.

Because the main material of this product is a plastic foam, the weight of shingle is greatly reduced, the steel screen layer that is provided with in the plate can improve the intensity of sheet material greatly, the breakage-proof effect is splendid, the glass fiber reinforced plastic composite bed of upper surface improves the water resistance of sheet material greatly, and the heat insulation shockproof effect of this product is also more satisfactory.This production cost is low, can reduce construction costs and difficulty of construction, is the regeneration product of existing shingle.

4 times plastic foam layers of plastic foam layer 3 glass fiber reinforced plastic composite bed on 1 steel screen layer 2

Below in conjunction with description of drawings embodiment of the present utility model:

Select a plane gauze wire cloth (1) for use, adopt common plastic foamed technology directly to make the plastic foam laminate and also above-mentioned steel screen layer (1) is wrapped in the middle of plastic foam layer (2) and the following plastic foam layer (4), paper one deck glass fiber reinforced plastic composite bed (3) gets final product on last plastic foam layer (2) again.

Claims

1, a kind of Light wt. roofing slab is a stratiform structure, it is characterized in that clamping has a steel screen layer (1) between last plastic foam layer (2) and following plastic foam layer (4), top one deck glass fiber reinforced plastic composite bed (3) in addition of above-mentioned last plastic foam layer (2).
