现浇混凝土夹芯复合外墙由以下几部分组成: 结构层——外墙的承重结构部分,为现浇钢筋混凝土,根据结构设计需要确定其厚度和配筋。一般厚度为15cm左右。保温层——采用导热系数小于0.698W/(m·K)的高效保温材料,同时应具有一定的抗弯强度,以保证墙体成型时能够抵抗混凝土的侧向压力。一般选用4～5cm厚聚苯乙烯泡沫塑料板(质量密度在20kg/m~3以上)。
The cast-in-situ concrete sandwich composite external wall consists of the following components: Structural layer - The load-bearing structural part of the external wall is cast-in-place reinforced concrete, and its thickness and reinforcement are determined according to structural design requirements. The general thickness is about 15cm. Insulation layer - high thermal insulation material with a thermal conductivity less than 0.698W/(m·K), and a certain degree of bending strength, to ensure that the wall can resist the lateral pressure of the concrete. General use of 4 ~ 5cm thick polystyrene foam board (mass density of 20kg/m ~ 3 above).
