Filling-type heat-insulating bearing composite board for building

A filling-type heat-insulating bearing composite board for building overcomes defects of current building surface board on incapability of independently bearing, etc., and includes upper and lower surface materials and a core material. The peripheries of the upper and lower surface materials clamp a sealed support frame therebetween, a core material filling hole and multiple vent holes are disposed along the periphery of the sealed support frame, and communicate with the closed space enclosed by the upper and lower surface materials and the sealed support frame, respectively; and the core material filled in the closed space is a one-step cast filling core. The composite board provided by the utility model has a reasonable structure design and is easy for manufacturing and construction, has the characteristics of light weight, good heat insulating performance, compression resistance and durability, and can be used alone as a bearing board while further improving the functions such as sound insulation and fire resistance; the natural foaming material can be replaced according to actual requirement, so that the filling core formed from the natural foaming material by solidification can completely satisfy different requirements of heat insulation, sound insulation and other performances; and the application range of the composite board is widened.
