Analysis of thermal bridge of door and window opening of low-rise fabricated steel structure with ultra-low energy consumption

According to the characteristics of climate zones in Hebei Province, this paper analyzes the low-rise fabricated steel structure ultra-low energy building door and window openings without thermal bridge optimization, and studies the temperature and the heat flux of the door and window opening under the addition of C-shaped steel reinforcement and the addition of anti-corrosive wood, Different optimization schemes with external and external installations method, different thermal insulation frame lengths. Through simulation analysis and experimental verification, when conditions permit, the low-rise fabricated steel structure ultra-low-energy building door and window openings are selected to add anti-corrosion wood, external installation, and insulation material compression frame of 100 mm. The temperature distribution is uniform and there is no serious thermal bridge defect.
