STRUCTURE FOR BLOCKING HEAT TRANSFER THROUGH THERMAL BRIDGE OF CURTAIN WALL BUILDING AND CONSTRUCTION METHOD THEREFOR

摘要

Disclosed are a structure for blocking heat transfer through a thermal bridge of a curtain wall building and a construction method therefor. The structure comprises a curtain wall (11), an indoor metal keel (12), and an indoor decorative board (13). The curtain wall (11) is fixed to an outer side of the indoor metal keel (12). The indoor decorative board (13) is fixed to an indoor exposure portion of the indoor metal keel (12). Heat insulating strips (15) made of aerogel heat insulation blankets and covering the exposure portion are clamped and fixed between the exposure portion of the indoor metal keel (12) and the indoor decorative board (13). The structure for blocking heat transfer through a thermal bridge of a curtain wall building is simple in structure, has a convenient construction process, high structural strength, good fireproof performance and low costs, and can greatly improve the energy-saving effect of the curtain wall building. The structure is especially suitable to improve or reconstruct a curtain wall building with poor heat insulation performance having already been built and in use.
