72m 跨度屋面网架采用累积滑移工艺，场地受限情况下不占比赛区施工。A 72m-span roof frame positioned by incremental sliding — no crane access needed over the court.
本项目体育馆屋面为 72m 跨度螺栓球网架，因场地四周已建配套建筑，大型吊车无法进入比赛区上方作业。
方案采用累积滑移：在馆内一端设置拼装平台，网架分段拼装后逐段向前滑移，直至整体就位。全程无需大型吊车上场，比赛区地面与看台零损伤。
对于场地受限的大跨项目，「拼装位置」和「就位位置」分离的滑移工艺是性价比很高的选择。类似的思路也适用于改扩建项目中的新增屋面。
This gymnasium roof is a 72m-span bolted-ball space frame. With supporting buildings on all sides, large cranes could not work above the court.
The solution was incremental sliding: a platform at one end, sections assembled and slid forward one by one until the whole frame reached position. No heavy crane access required, and the court floor and stands were untouched.
For wide-span projects with constrained sites, separating the assembly zone from the final position is a cost-effective answer — the same idea works for new roofs in renovation projects.
