Embodiment 1
[0073] Embodiment one sees Figure 1-4 , Figure 12 , Figure 13 As shown, this prefabricated composite wall panel with door and window openings has door and window openings 22 (wherein figure 1 The middle is the window opening, Figure 12 The middle is the door opening), and the board body has a structural layer 1, an insulating layer 3 and a protective layer 2 in order from the inside to the outside. There is a steel cage in the structural layer, the insulating layer 3 is extruded polystyrene foam board, and the protective layer 2, there is steel mesh in the concrete, and the structural layer 1, insulation layer 3 and protective layer 2 are interspersed and anchored together by connecting pieces 5 distributed in dots, and the distribution diagram of connecting pieces can be found in Figure 15 . The left and right edges of the protective layer 2 and the thermal insulation layer 3 protrude from the structural layer 1, and the lower edge of the protective layer 2 extends d...
Embodiment 2
[0081] Embodiment two see Figure 5 , the outer surface of the protective layer 2 is connected with an outer decorative layer 4, and the outer decorative layer 4 is a face brick, a paint or a decorative board.
[0082] When the outer side of the protective layer does not need an outer decorative layer, or although an outer decorative layer is required, but the outer decorative layer is not a facing brick, there are two methods for making this prefabricated composite wall panel with door and window openings.
[0083] The first kind: step 1, assembling formwork; Step 2, place reinforcement cage, reinforcement ring 15 and internal thread sleeve 9 on the base form, comprise horizontal tie reinforcement 14, vertical connection reinforcement 10 on the reinforcement cage, reinforce reinforcement sleeve 6 is fixedly connected with the reinforcement cage of the structural layer, and the short grouting pipe 13 and the short grouting pipe 11 are fixedly connected with the steel bar sleev...
