针对轻钢装配式建筑中轻钢龙骨构件与不同部位连接处的热桥问题，提出一种将生物质保温材料对热桥部位进行局部保温的解决方法。运用ANSYS Fluent仿真分析软件对生物质保温材料的应用场景进行稳态传热模拟，分析该保温材料的绝热性能以及保温处理方式对热桥效应的影响。研究结果表明：将生物质保温材料应用于热桥部位，对热桥效应有一定的削弱作用。通过最优的保温处理措施，外墙体热桥、外墙-外墙热桥和外墙-内墙热桥的热桥影响区域分别缩短了35%、4.5%、17.6%，热桥线性系数分别减少了0.07、0.14、0.07 W／（m·K），并且热桥部位耗热量得到大幅降低。

A solution was proposed for locally insulating thermal bridge components of light steel keel systems and various connections in light steel prefabricated buildings through the application of biomass insulation materials. Steady-state heat transfer within relevant application scenarios was simulated using ANSYS Fluent simulation analysis software to evaluate the thermal insulation performance of such materials and investigate the influence of different insulation treatment approaches on thermal bridging effects. The research results demonstrate that implementing biomass insulation materials at thermal bridge locations produces a measurable attenuation effect on thermal bridging phenomena. Through optimized insulation interventions, the affected zones of external wall thermal bridges, exterior-external wall thermal bridges, and exterior-interior wall thermal bridges are reduced by 35%, 4.5%, and 17.6% respectively. Correspondingly, the thermal bridge linear coefficients experiences reductions of 0.07, 0.14, and 0.07 W/(m·K), while significant reductions in heat loss within thermal bridge areas are observed.
