Further preferred, the tensile bond strength > 0.6MPa of the adhesive linkage between described reinforced concrete wall panel layer and insulation layer.
Further preferred, between described heat preservation plate material, adopt concave-convex type, stepped ramp type or falcon to connect type overlapping mode, insulation layer is according to the size of external wall plate, and appropriate design is cut apart the size of heat preservation plate material, avoids overlap joint as far as possible.Described heat preservation plate material, in the time that needs overlap, adopts concavo-convex, step, falcon to connect type overlap joint between sheet material, faying surface adopts cementing agent sealing simultaneously, and the insulation layer " seamless process " that can realize whole facing-wall board connects.
Further preferred, between described reinforced concrete wall panel layer and insulation layer, directly adopt concrete grout to bond between insulation layer and finish coat.
Further preferred, between described reinforced concrete wall panel layer and insulation layer, add fiber reinforced material between insulation layer and finish coat, to improve the performance such as shock resistance, slip-off preventing, anti-cracking of finish coat.
The beneficial effects of the utility model are:
The decoration integrated side fascia of a kind of structural thermal insulation of the utility model, has good structure, insulation and decoration functions.Produce by batch production, effectively reduce the production cycle, save production cost, produce affected by environment little, further compressed products overall manufacturing cost.
