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...

Abstract

The invention discloses a precast composite wallboard with door/window holes and a manufacturing method thereof. The body of the precast composite wallboard is provided with door/window holes thereon and is also sequentially provided, from inside to outside, with a structural layer, a heat preservation layer and a protective layer, wherein the structural layer is internally provided with a reinforcing cage, concrete of the protective layer is internally provided with a reinforcing mesh, the structural layer, the heat preservation layer and the protective layer are anchored with each other in a penetrative manner via connectors which are distributed in a spotted manner, the left and right edges of the protective layer and the heat preservation layer protrude to the structural layer, the lower edge of the protective layer extends downwards out of a convex opening, the top parts of the protective layer and the heat preservation layer protrudes upwards to the structural layer, and the upper edge of the protective layer is provided with a concave opening corresponding to the convex opening of the adjacent precast composite wallboard at the upper layer. The wallboard has the advantages of simplifying construction procedures, speeding up construction speed and reducing project cost. In addition, the products precast in factory are consistent in specification and quality, the construction quality of building structure can be fully guaranteed, and the wallboard can be extensively applied to the construction of reinforced concrete buildings in the construction industry.

Description

technical field [0001] The invention relates to a prefabricated reinforced concrete external thermal insulation wallboard and a manufacturing method thereof. Background technique [0002] The current residential construction adopts the method of pouring concrete on site. The on-site construction of the main structure of the outer wall generally needs to go through the construction process of supporting formwork, laying steel bars, pouring concrete and then removing the formwork. A series of tedious work such as thermal insulation layer construction, exterior decoration layer construction and interior decoration construction. Each square meter of housing will cause energy consumption equivalent to 20 kg of standard coal, 0.05 cubic meter of water consumption, 3% loss of concrete, 3% loss of steel and 0.05 cubic meter of wood consumption. Calculated based on the currently commonly used rough house delivery model, during the renovation process, each household will bring about ...
