Background technology
Building roof is an important component part of architectural exterior-protecting construction, and its power consumption accounts for about 10% of whole building.Since cold in winter and hot in summer, the wind and rain invasion and attack, the weathering at sunshine, the selection of the thermal insulation of roof roofing, waterproof, efflorescence prevention and construction are more and more paid attention in the industry.Existing roofing construction technical scheme is to be followed successively by on building roof concrete core unit (or cast-in-situ concrete) substantially: cement mortar screeding layer, vapour barrier, insulation layer, a slope layer, leveling layer, waterproofing course, fish tail and waterproof layer, back-up coat etc.The inverted roof structure then is that waterproofing course is descending, and insulation layer makes waterproof roll avoid weathering last, and has saved 2 procedures.The inverted roof material product that occurs just at present, more with cast-in-place thermal-insulating layer, construction technology is still comparatively complicated.At present, though the situation of thermal insulation thermal insulation board also occurred partly using, because rain erosion, weathering, used warming plate is fragile, all need make topping in addition on warming plate, has not only increased building costs, and construction is complicated, easy-maintaining not.
Summary of the invention
The purpose of this utility model is to be the deficiency that solves the problems of the technologies described above, and a kind of high insulating effect is provided, long service life, and the roof heat insulation heat-insulating composite panel that is used for the inverted roof structure of water proof anti-seepage.
The utility model is the deficiency that solves the problems of the technologies described above, the technical scheme that is adopted is: a kind of inverted roof heat-insulating composite plate, form by the cement sand bed and the light granules bed of material, the cement sand bed and the light granules bed of material are one-time formed integrative-structure, are provided with the guiding gutter parallel with the edge on the surface of cement sand bed.
The utility model, the thickness of the described light granules bed of material are 30~100mm.
The utility model, described cement mortar layer thickness is 10~30mm.
The utility model on the surface course of cement sand bed, also is provided with colored lacquer painting.
The utility model, the guiding gutter of cement mortar laminar surface setting is used for the water conservancy diversion rainwater, can effectively improve the anti-permeability performance of warming plate, and expanding with heat and contract with cold of can preventing that variations in temperature from causing cause the cracking of heat-insulating composite plate, improves application life.
The utility model, the cementitious matter that the light granules bed of material is made up of polystyrene foaming granule material and cement, Calcium Carbide Ash and salt gypsum etc. mix and constitute, and have good heat-insulating property.
The utility model, cement sand bed hard such as porcelain, light is dazzling, has the thermal-radiating effect of reflection sun in summer light, can effectively completely cut off heat and enter within doors, reduces the interior temperature in summer; Have the erosion of resisting the elements, efflorescence prevention weather resistance, increase the service life.If then albedo is stronger to use white cement.Though the light granular material layer material belongs to light material but still water proof anti-seepage, avoid sleet to infiltrate freeze-thaw damage.The cement sand bed and the light granules bed of material closely are composited, and do not add layer in the middle of not needing on the structure, one-time cast-forming, and combination in the table, muddy is one, has complementary advantages.
The utility model, heat-insulating composite plate do not need supporting leg built on stilts; When laying roof panel, sit the slurry jointing, one-shot forming.Be particularly useful for robbing the roofworks that works to tight deadlines.
The beneficial effects of the utility model are:
1, heat-insulating composite plate has excellent heat insulation performance.
2, water proof anti-seepage, efflorescence prevention, long service life.
3, the surface need not to do in addition overcoat, has simplified construction technology, has saved cost simultaneously.
The specific embodiment
In conjunction with the accompanying drawings, a kind of inverted roof heat-insulating composite plate, form by the cement sand bed 1 and the light granules bed of material 2, the cement sand bed 1 and the light granules bed of material 2 are one-time formed integrative-structure, be provided with the guiding gutter parallel 3 on the surface of cement sand bed 1 with the edge, guiding gutter 3 is divided into horizontal and vertical both direction setting, and the guiding gutter 3 that vertical and horizontal are provided with intersects mutually, is latticed.
The thickness of the described light granules bed of material 2 is 30~100mm.
Described cement sand bed 1 thickness is 10~30mm.
On the surface course of cement sand bed 1, also be provided with colored lacquer painting.
Marginal surface at cement sand bed 1 tilts, and makes after two warming plate butt joints, forms a guiding gutter at seam crossing.
