Abstract

The utility model provides a sandwich roof tile, which is a roof covering layer, in particular to a roof tile with a heat insulating core layer. The utility model includes an aging preventing surface layer 1, a reinforcing layer 2, and a basic layer 4 which can increase the strength of the roof tile; all the layers are integrated together. The utility model is characterized in that the heat insulating core layer 3 is concreted between the reinforcing layer 2 and the basic layer 4, and the top of the core layer 3 together with the reinforcing layer 4 and the surface layer 1 assume wave shapes. The utility model solves the problem that the present roof tile is ponderous and breakable with poor rigidity; or has unideal heat insulating performance; or although the roof tile has air temperature regulating space inside, the ponderous and complex structure and the complex special mould for producing the tile are troublesome with higher cost. The utility model has the characteristics of excellent strength and rigidity, aging resistance, heat preservation, convenient production, and low cost.

Description

The sandwich roof tile

Technical field

The utility model relates to a kind of roof covering, especially a kind of roof tile that has the sandwich layer of thermal insulation.

Background technology

Existing roof tile commonly used, as grey tile, cement tile, glass steel tile, glass steel corrugated tile etc., preceding two kinds of fragmentations easily, and also very heavy; Though the two kinds of quality in back are light, its is easily fragmentation and poor rigidity still, so very yielding after stressed.Chinese patent 91201721.X disclosed ' the compound hard roof tile of organic-inorganic ', its shortcoming is: heat-insulating property is undesirable, so summer is not heat insulation, winter is not warming.Chinese patent 94209374.7 disclosed ' prestressed reinforced concrete from water-proof roofing watt ', though but it is provided with the space of climate comfort in roof tile, but need special-purpose mould when its structure bulky complex, manufacturing, so make trouble and the more high shortcoming of cost.

Summary of the invention

Technical problem to be solved in the utility model, be to overcome the shortcoming that exists in the above-mentioned prior art, a kind of good effect of heat insulation is provided, quality is light, intensity is high and the sandwich roof tile of good rigidity, and makes it have characteristics such as simple in structure, easily manufactured, that cost is low.

The technical scheme that the utility model adopted is: it includes energy age inhibiting surface layer, enhancement Layer, can increase the basic unit of roof tile intensity, each layer is solidified as a whole each other, be characterized in: fixed sandwich layer that can thermal insulation between enhancement Layer and basic unit, and the top of sandwich layer and enhancement Layer, surface layer are corrugated together.

The utility model sandwich roof tile, its sandwich layer height is not less than 5cm.

The utility model sandwich roof tile, the height that its surface layer height is not less than 0.1mm, enhancement Layer and basic unit is not less than 1mm.

The beneficial effects of the utility model are: 1) by after the sandwich layer of age inhibiting surface layer, enhancement Layer, thermal insulation and basic unit are consolidated into one, not only make the utility model sandwich roof tile have enough intensity, rigidity and good anti ageing property, thereby prolong its application life, but also it is good to make it have in light weight and performance thermal insulation, that is summer can be heat insulation, can be incubated winter; 2) the utility model roof tile is simple in structure, makes the fixed each other one of each interlayer in manufacture process with hot pressing, thus do not need the specialized designs mould, need not smear viscose glue yet, so easily manufactured, cost is low; 3) four layers of composition the utility model sandwich roof tile, except the height of sandwich layer is big, other height of three layers is all very little, and they are all with the material of lightweight, as material such as glass fiber reinforced plastic, polystyrene rigid foams, so it is in intensity height, good rigidity, its quality is also lighter.

Description of drawings

Fig. 1 is the stereogram of the band cutting plane of the utility model sandwich roof tile;

Fig. 2 is the utility model roof tile a kind of connected mode in use, and it links into an integrated entity front and back for two pieces watts in the mode of overlap joint.

The specific embodiment

First embodiment. can see that from Fig. 1 present embodiment sandwich roof tile includes surface layer 1, enhancement Layer 2, sandwich layer 3, basic unit 4, each layer is solidified as a whole each other, and the top of sandwich layer and enhancement Layer, surface layer constitute corrugated together.

Surface layer 1 in the utility model sandwich roof tile is a kind of colored polyester film layer, and it has age inhibiting performance; Enhancement Layer 2 and basic unit 4 all can be by the resin glass fibre reinforced plastics manufacturings, so that roof tile has intensity preferably; Sandwich layer 3 is to be made by self-extinguishing polystyrene rigid foam, and the unit weight of this material is 0.3g/cm ³, thermal conductivity is 0.032mw/mk, so its quality performance light, thermal insulation is good.

The utility model sandwich roof tile during fabrication can be when glass fiber reinforced plastic be made, with surface layer 1, enhancement Layer 2, sandwich layer 3, basic unit's 4 four stacked closing, and pressing on combined shaper, so that their each interlayer is consolidated into one.During pressing, the corrugated of its top also has the ripple one-shot forming because of the cope match-plate pattern of combined shaper.

Second embodiment. different is that it limits the height of sandwich layer with first embodiment for it, and the height of sandwich layer 3 is not less than 5cm, that is sandwich layer height 〉=5cm.

The 3rd embodiment. different is that it limits the height of surface layer, enhancement Layer and basic unit with first and second embodiment for it, and promptly the surface layer height is not less than 0.1mm, just 〉=0.1mm; The height of enhancement Layer and basic unit is not less than 1mm respectively, that is 〉=1mm.

If any actual needs, the bottom of the utility model sandwich roof tile can be the same with the shape at top, and promptly Qi Ding, two sides, the end all can have corrugated.This bottom surface ripple also is the ripple one-shot forming that the lower bolster by combined shaper is carved with.

When using this practical sandwich roof tile, can dissect with reference to the mode of representing among Fig. 2 in advance, then two roof tiles are overlapped into one.
