Project Background：
Vigorously developing ultra-low energy consumption buildings is able to significantly improve building energy conservation efficiencies during their service life and is vital to achieve the targets of "peak carbon dioxide emissions" and “carbon neutrality”. Insulated precast concrete sandwich walls (IPCSWs) is a structural-insulation integrated technology, which realizes the same service life of the insulation system and the main structure. In order to apply IPCSWs in ultra-low energy buildings, it is necessary to comprehensively improve the thermal and combustion performance of the insulation layer, control the wall thickness and their cost and optimize the fiber-reinforced polymer (FRP) connectors.
Aims & Goals:
1. To study the thermal performance and combustion performance of EPS, XPS, PU and PIR;
2. To develop FRP connectors, optimize the mix ratio and manufacture technology, and propose the calculation methods for their tensile and shear capacity, shear-slip model and durability prediction model;
3. To form a set of technologies in design-manufacture-construction of precast concrete sandwich facade (PCSF).
