摘要
直立锁缝钢屋面通过可滑移支座消除屋面板与屋面结构间因热胀冷缩内应力带来的损害。本研究通过测温实验,实测了金属屋面的热胀冷缩量,构造了数理模型,并以LSⅢ镀锌钢板屋面系统为例,得出施工时此类屋面系统的最大单坡长度的计算公式。
The damages of standing seaming steel roof structures due to thermal expansion and contraction can be avoided by using moveable supporting blocks. The deformation of the metal roof is measured by temperature measure test. The mathematical model of it is constructed. The paper points out the maximum length calculating formula of single slope of this roof systems with an example of LS Ⅲ galvanized steel roof system.
