The invention discloses a building external wall heat insulation
structural system and a safety degree evaluation method thereof. The building external wall heat insulation
structural system and the safety degree evaluation method thereof aim to solve the problems that concentrated
thermal bridge is generated because of a connecting piece, and the life of the building wall body is short. The structure of the building external wall heat insulation
structural system comprises a concrete pavement, a load-bearing structural wall, a heat
insulation layer, a positioning
cushion block and a connecting component. The connecting component comprises a steel
wire mesh sheet and a connecting piece fixed to the steel
wire mesh sheet, the connecting piece penetrates through the heat
insulation layer and is fixed to the structural wall and the concrete pavement, and the positioning
cushion block is used for fixing the heat
insulation layer and the steel
wire mesh sheet to form a steel wire mesh frame plate. According to the building external wall heat insulation structural
system and the safety degree evaluation method thereof, the method for evaluating the safety degree of the building external wall heat
insulation system for the first time is provided, a heat insulation wall face with the appropriate thickness is selected to be put into use according to a result calculated through the method, and
moisture condensation caused by concentrated
thermal bridge of the connecting piece can be effectively overcome.
