本文初步讨论了建筑材料的热运动理论和■房结构的温度■差问题,结合近代工业建筑的结构特点和建筑材料的特性,作者认为:大部工业厂房中可以不考虑温度影响问题,即不必设立温度伸缩缝或采用其他改善措施。本文还根据我国各地区气候的不同,分别考虑了室外构筑物温度缝的距离问题。对少数室内浇灌的钢筋混凝土构筑物的温度影响问题也作了分析。 This paper discusses the thermal movement theory of building materials and the temperature difference of the building structure. Combined with the structural features of modern industrial buildings and the characteristics of building materials, the author believes that most of the industrial plants can ignore the issue of temperature, ie Set up temperature expansion joints or use other improvements. This paper also considers the distance problem of temperature joints of outdoor structures according to the different climates in different regions of China. The temperature effect of a few indoor-concrete reinforced concrete structures has also been analyzed.
