前言 近代各种大型公共建筑的平面尺寸远超过建建设计规范中温度伸缩缝的许可间距。因此,根据规范在建筑物上每隔一定间距就必须设置温度伸缩缝。这种贯通整个公共建筑(基础以上)的温度伸缩缝对建筑物的美观起着不良影响。特别是在某些纪念性公共建筑上设置伸缩缝是建筑师们最感苦恼的事。在—些带有巨型大厅的公共建筑中,例如具有各种壳体屋盖的车站,剧院,会堂,杂技馆等建筑中,做伸缩缝不仅对建筑艺术起不良作用,而从桔构受力观点看来,往往是不 Foreword The size of various large-scale public buildings in modern times far exceeds the permitted spacing of temperature expansion joints in the construction and design specifications. Therefore, a temperature expansion joint must be set at regular intervals on the building according to the specifications. This temperature expansion joint running through the entire public building (above the foundation) has an adverse effect on the aesthetics of the building. In particular, the installation of expansion joints in certain monumental public buildings is the most frustrating thing for architects. In public buildings with giant halls, such as stations, theaters, auditoriums, acrobatics and other buildings with various shell roofs, doing expansion joints not only adversely affects the architecture art, but also exerts force on the orange structure. From the viewpoint, it is often not
