Problems solved by technology

[0006] The purpose of the present invention is to provide a prefabricated exterior wall panel with phase change materials wrapped in steel grid and aluminum film and its manufacturing method, to solve the problems of the existing sandwich insulation wall panels, the connection reliability is still questionable, and there are cold and hot bridges The technical problem of the phenomenon is to solve the technical problem that the thermal conductivity of the thermal insulation material is low, and there is no function of temperature adjustment and energy storage, resulting in a large temperature difference between indoor and outdoor, loss of energy consumption, and reduction of indoor human comfort.

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...

Abstract

The invention relates to a prefabricated external wall panel for a PCM (phase change material) wrapped by a steel grating aluminum film and a preparation method thereof. The prefabricated external wall panel comprises an internal vane-board, an external vane-board and a phase change composite insulating layer, and the phase change composite insulating layer comprises a core plate, insulating tinsel and a support connecting box; and the core plate is integrally made from a phase change material, the support connecting box comprises a steel grating skeleton and a concrete intercepting web, and gaps between the support connecting box and the core plate form a cavity together. An outer wall of the steel grating skeleton is connected with an inserting rod, the external vane-board and the internal vane-board are respectively connected with the support connecting box through the inserting rod, and two ends in a width direction of the prefabricated external wall panel are corresponding to a convex head end and a concave head end which form pass lengths respectively. The prefabricated external wall panel is good in connecting performance, has advantages of storing energy and reducing indoor and outdoor temperature difference, and realizes the target of combining building energy conservation with a fabricated building.

Description

technical field [0001] The invention belongs to the field of building components, and in particular relates to a prefabricated sandwich exterior wall panel with a steel grid grid aluminum film wrapped in a phase change material and a manufacturing method thereof. Background technique [0002] As a big construction country, our country's annual new building area ranks among the top in the world, which means that there will inevitably be a lot of energy consumption in the construction process, and at the same time, the construction form of buildings has become a problem that our country pays more attention to now. Therefore, the effective combination of building energy saving and assembly has become a hot research topic in today's construction industry. [0003] In recent years, prefabricated buildings have gradually entered the right track, and prefabricated shear wall structures have become an upsurge in assembling integral concrete structures. How to effectively combine ene...
