Abstract

Abstract

The prefabricated sandwich wall is a new type of wall, which integrates load-bearing, heat preservation and light weight. It consists of inner and outer leaf walls, connector and intermediate insulation board. The connector is a key component for connecting the inner and outer leaf walls and the thermal insulation boards. The current connector on the market are mostly imported from abroad, and the price is very high, it is not conducive to be widely used. Therefore, it is necessary to find a new type of connector with good mechanical properties, thermal insulation performance and low price. In the paper, glass fiber reinforced plastics profile was selected as the material of connector for the sandwich wall. Compared with the conventional connector, it showed the advantages of no cold and heat bridge, high strength, excellent corrosion resistance and low price. The pull-out and shear tests on the prefabricated sandwich wall with different types and sizes of fiberglass reinforced plastics were peformed, including rods, plates, L-section, H-section and C-section profiles. The thermal test of the sandwich wall was also carried out. The results showed that the glass fiber reinforced plastics had good shear and tensile strength as well as thermal insulation performance. The C-section connector had the largest crack-resisting load and ultimate load, which might be more suitable for the inner connector of prefabricated sandwich walls.
