The specific embodiment
Below in conjunction with drawings and Examples in detail the present invention is described in detail.
Concrete composite wallboard of the present invention, as shown in Figure 1, be the big cavity concrete structure of cuboid, form by bar frame 1 and the layer of concrete 2 that is cast in around the bar frame 1, the thickness of layer of concrete 2 is average out to 20～50mm, bar frame 1 is that the main grid structure 5 of rectangle is formed with the fabricated bar 4 that inner three rows that are provided with are fixedlyed connected with the upper and lower of main grid structure by the longitudinal section, is sound-insulating plate 2 in the formed big cavity of steel concrete.Main grid structure 5 is an individual layer, also can be double-deck.Also can be provided with wire gauze or fiberglass gridding cloth, to play the effect that strengthens intensity and cracking resistance in the inboard or the outside of main grid structure 5.
The sound-insulating plate can adopt polystyrene foam plastics EPS plate (expansion type) or XPS plate (extrusion type), perhaps adopts phenolic resins warming plate, rock cotton board, pearlite heat-insulation plate, foam glass board or mineral wool board.Concrete is light weight concrete construction or ordinary concrete or high-strength concrete.
The surface density of the combined wall board of making is 90kg/m
