针对砖混结构房屋的温度裂缝问题 ,选取某一建筑进行温度场测试 ,并与理论分析的结果对照 ;计算了屋面板温度、墙体温度和抗拉强度 ,为改善保温层、降低顶板温度、减小温度应力的抗温度裂缝设计方法提供了依据 .试验结果表明 :屋面昼夜温度呈波状变化 ,有延迟 ;内纵墙更应提高砂浆强度 ;注意保温材料吸湿后隔热性能的变化 Aiming at the problem of temperature cracks in masonry-concrete buildings, the temperature field of a building was selected and compared with the results of theoretical analysis. The roof temperature, wall temperature and tensile strength were calculated. In order to improve the thermal insulation and the roof temperature, Reduce the temperature stress of the anti-temperature crack design provides the basis for the test results show that: roofing day and night temperature changes with a wave, there is a delay; the vertical wall should be to increase the mortar strength;
