【 摘 要 】

Based on the thermal performance test of precast concrete insulation sandwich wall, the finite element model of the wall is established to analyze the influence of insulation mortar layer thickness and insulation layer material on the insulation performance of the wall. The results show that with the increase of insulation layer thickness, the insulation performance of wall with insulation mortar and EPS as insulation layer can be improved to a certain extent. After EPS is used as insulation material, the insulation performance of the wall can be improved obviously.
