摘要
在某楼裙楼幕墙工程中,遇到了点支承玻璃幕墙的竖向拉索与点支承夹层玻璃雨篷的变截面焊接工字钢悬臂梁腹板相交叉构造。传统构造是将竖向拉索处的变截面焊接工字钢悬臂梁作为竖向拉索的一段,使两个不相关的受力体系相连,影响使用功能。通过运用功能定位、排列选择的方法剖析了该构造,创新出过索管替代变截面焊接工字钢悬臂梁腹板交叉段的新构造,使两个受力体系彻底分离,保证了使用功能,安装简便,降低了成本。
In a podium building curtain wall engineering, longitudinal cable of point-supported glass curtain wall and variable section welded I-beam web plate of point-supported laminated glass canopy cross through each other. In traditional construction, the variable section welded I-steel cantilever beam is used as a segment of longitudinal cable to connect two unrelated force systems. The structure is analyzed by using various methods, such as functional positioning and arrangement selection. An innovative structure which uses cable- through tube to replace the cross segment of variable section welded I-steel cantilever beam web plate. In this way, the two force systems are completely separated from each other, ensuring service functions, realizing convenient installation process and reducing the construction cost.
