Embodiment Construction
[0038] Examples see Figure 1-5 As shown, a prefabricated exterior wall panel with phase change material wrapped in steel grid and aluminum film, including reinforced concrete outer leaf plate 1 of the same size, reinforced concrete inner leaf plate 2 and a phase change sandwiched between them Composite insulation. The outer leaf plate is used as the protective layer of the phase change composite insulation layer, and the thickness is usually 50mm-60mm; the inner leaf plate is used as the load-bearing part of the shear wall, and the steel bars are configured according to the design, and the thickness is usually 100mm-120mm; the usual thickness of the phase change composite insulation layer 40mm-70mm.
[0039] The phase-change composite thermal insulation layer includes a core board 3 , an insulation metal foil 4 wrapped on the surface of the core board, and a supporting connection box 5 for supporting the core board.
[0040] The core board is integrally made of composite ph...
