摘　　要：对夹心秸秆混凝土砌块试点建筑墙体进行了保温性能试验。试验测得夹心秸秆混凝土砌块墙体处夹心秸秆混凝土砌块传热系数为1.04 W(/m2.K),钢筋混凝土芯柱位置传热系数为1.96 W(/m2.K);作为对照混凝土空心砌块墙体处混凝土空心砌块传热系数为1.40 W(/m2.K),钢筋混凝土芯柱位置传热系数为1.82 W(/m2.K)。实验结果与前期实验室试验结果吻合较好。钢筋混凝土芯柱部位为保温隔热薄弱区,需采取加强保温的措施。In this paper,thermal insulation performance of concrete block filled with stalk wall was tested. Also concrete hollow block wall and wall with reinforced concrete core column were tested. The experimental results indicated, that the thermal insulation coefficient of the concrete block filled with stalk wall was 1.04 W/（m2.K）,while the wall reinforced concrete with core column was 1.96 W/（m2.K）. Moreover the thermal insulation coefficient of concrete hollow block of concrete hollow block wall was 1.40 W/ （m2. K） , while the wall with core colunm was 1.82 W/（m2. K）. The site experimental results coincide with former laboratory results. The position of core column has weak thermal insulation performance. Appropriate measures should be taken to increase thermal insulation performance.
