轻钢屋面檩间支撑体系探讨

檩间支撑在轻钢屋面系统中占有很重要的位置,它能有效地将檩条倾覆力传递给刚架,起到提高檩条侧向稳定与屋面整体刚度的作用。分析不同形式的檩间支撑及直拉条在不同受力情况下的支撑体系优缺点,并提出用C型钢作直拉条的檩间支撑体系。分析表明:C型檩间支撑刚度好,连接方便,而且有很好的经济效益,是值得推广的一种檩间支撑形式。

INVESTIGATION FOR THE PURLIN BRACE SYSTEM OF LIGHT-GAUGE BUILDINGS

The purlin brace is very important in the light-gauge steel roof system.It can effectively transfer the capsizing force of the purlin to the rigid frame,which can improve the lateral stability of the purlin and the overall rigidity of the roof.Different styles of purlin brace system are studied,and a new purlin brace system of C-purlin brace is also recommended.Analysis shows that the C-purlin brace has better rigidity and connecting convenience,also has good economic benefit.So the C-purlin brace system is...
