Large GRPC decorating pendant and manufacturing method

The invention discloses a large GRPC decorating suspended board and a manufacturing method. The large GRPC decorating suspended board comprises underwall reinforced concrete, lightweight aggregate concrete, sidewall reinforced concrete, prefabricated GRC face boards, a GRC face layer and hoisting parts, wherein the GRC face layer is located on the outer side of the prefabricated GRC face boards, the underwall reinforced concrete is located on the GRC face layer, the lightweight aggregate concrete is located on the underwall reinforced concrete, the sidewall reinforced concrete is arranged between the prefabricated GRC face boards and the GRC face layer, bottom transverse frame ribs and sidewall longitudinal frame ribs form a whole frame, the bottom transverse frame ribs serve as secondary beams, and the sidewall longitudinal frame ribs serve as main beams. The large GRPC decorating suspended board is reasonable in structure and overcomes the defects of poor strength and impact resistance of traditional GRC boards. The large GRPC decorating suspended board produced by means of the manufacturing method meets the building design requirement for strength, is good in flatness and appearance effect, meets the strength design requirements and also meets the appearance design requirements.
