Research on Self-thermal Insulation Wall Construction Technology of Autoclaved Aerated Concrete Block

Abstract

To promote the application of autoclaved aerated concrete(AAC) block self-thermal insulation system in severe cold and cold zones, this paper proposes the construction of self-thermal insulation wall, shear wall insulation treatment measures and the detail construction of beam column thermal bridge. According to design standard for energy efficiency of residential building, this paper analyzes the thermal performance of self-thermal insulation wall of AAC block, and focuses on the inner surface condensation trouble by illustrating the example of 200mm-thick reinforce concrete shear wall in Jinan region. The research results show that, AAC block of different levels with different thickness can meet the requirements of residential building energy conservation design standard in the cold and severe cold zones. The construction treatment of pasting heat-thermal plates outside concrete shear wall and smearing thermal-insulating mortar can avoid the inner surface condensation trouble of AAC block self-thermal insulation system wall.
