Abstract: With the rapid rising of labor costs and the disappearance of demographic dividend, traditional nationalconstruction industry is facing transformation, precast assembly buildings have been widely used in practical projects.Avoiding the disadvantages of the instability of grout socket connection quality control, double-superimposed shear wall withinsulation not only has good overall performance, but also achieves the integration of structure and thermal insulation, andhas a same life cycle as the structure, which has dominated application and research in recent years. The research progressof double-superimposed shear wall with insulation at home and abroad and the key problems existing in the promotion weresummarized, including the structural innovation of horizontal and vertical connection, the innovation of the insulationconnection of the shear wall with insulation, moisture transmission and temperature effect of the wall, and the fullycomposite panel, etc. , which provides reference for promoting the research and application of double-superimposed shearwall with insulation.

Keywords: double-superimposed shear wall with insulation; horizontal connection; vertical connection; insulationconnection; temperature effect; fully composite superimposed shear wall
