Roof slab
The utility model belongs to building materials, relates to a kind of Roof slab.
After the nature that finishes to eat birds and animals raw, occupy from the mankind, just begin to be converted into and settle down life, so the rise in house has just been arranged by grass.Along with the evolution of human civilization degree, the function in house also enlarges gradually.Distinguish with building purposes, can be divided into house, office, industrial building, farm house etc.Although these building application target differences, the modeling structure difference has a common ground: the roof is all arranged.The past roof Material is the most frequently used is exactly watt, or the precast plate made of steel concrete.Then popular in recent years iron sheet roof, iron sheet roof are that zinc-plated or color steel sheet etc. is made with tinplate.This building materials are because easy construction, the extremely favor of building operations department.But the house one on this iron sheet roof is to summer, and sultry difficult retaining often must hang the ceiling that a heat-barrier material is made in addition by means of other heat insulation material or on ceiling.And so, both caused the decline of chamber height, strengthened the cost in house again.Tracing it to its cause is because the iron sheet roof under the radiation of the sun, conducts heat within doors, causes interior temperature to raise, and the people is done not feel like oneself.
The purpose of this utility model is a kind of Roof slab of design, and this plate is laid convenient, and is durable, both can be sun-proof, can reduce noise again.
The purpose of this utility model realizes by following scheme: this Roof slab is the barrier layer that the pressing metallic film is made on the substrate layer of plate shaped sheet metal; Or in above-mentioned double-layer structure the puigging made by the macromolecule foaming thing of pressing one deck again.
Therefore this Roof slab has heat insulation function because the aluminium foil that barrier layer adopts vacuum evaporation to form is made, and smooth surface such as minute surface so when solar radiation, have very strong reflex, can stop heat radiation.General in addition iron sheet roof runs into rainy, can send drip to drip a noise of rattling away, but in the utility model owing to added puigging, above-mentioned noise can not reach indoor, but peaceful in the holding chamber.
Fig. 1 is the generalized section of a kind of structure of the present utility model;
Fig. 2 is the generalized section of another kind of structure of the present utility model;
Be described as follows below in conjunction with drawings and Examples:
In Fig. 1, Roof slab comprises substrate layer and barrier layer double-layer structure, and substrate layer 1 is a metal plate thin slice, and it has rigidity, difficult deformation, can aluminium sheet, iron plate etc. makes.Barrier layer 2 is a metallic film, its surface smoothing light.The material of can aluminizing on polyester film during making, forming aluminium foil be the best.Also can be between above-mentioned double-layer structure pressing one deck puigging 3 again, as shown in Figure 2.Puigging 3 is made for high molecular foam material, is the best with the PE expanded material especially.
When using this plate to build roof, the barrier layer that will have reflex is towards sunlight, and substrate layer is towards indoor, can play heat insulation, every the effect of noise.
