Aiming at the general problems of envelop wall panel about the existing building, such as large surface density, low strength, poor service performance and high maintenance cost, a kind of high-performance composite wall panel is proposed in this paper. This wall panel takes high toughness cement-based composite material as shell and inorganic light thermal insulation material as core part. Its surface density equals to or is less than 70 kg/m2, heat transfer coefficient equals to or is less than 1 W/ (m2·K ), and the minimum bending failure load equals to or is more than 8 times of wall panel weight. Combined with the characteristics of high-performance composite wall panel, the “removable connection system” and “beveled tongue and groove type” joint structure are proposed to realize the construction of high-performance composite wall panel without moisture, nondestructive free disassembly and green recycling.
