问题描述：
自行车馆工程钢结构型式采用非落地式人字柱支环梁和屋面网壳，钢结构为水平投影直径150m、跨度133.06m的空间双层焊接球球面网壳。自行车馆屋面钢结构型式世界少见，跨度亚洲第一，施工难度国内首创。最后一次提升采用了24根主桅杆加4根附桅杆，52台绞磨，投入提升劳动力600多人，提升时间3小时；网壳整体提升直径110m，重量460t，提升高度12m。
问题解答：
Bicycle Museum steel works non-drive-type character ring beam and roof-support network shell,150m diameter projection for the level of steel, double-span space 133.06m Registration Sphere welding surface shell.Bicycle Museum type steel roof elsewhere in the world, spans Asia, and the construction work is more difficult lifted.Kan used to upgrade the last 24 plus four main mast attached mast, 52 cutter grindinginvested more than 600 upgrade, upgrade time is 3 hours; Shell enhancing the overall diameter of 110m, weighs 460t.the height of 12m
The bicycle house project type of steel structure adopting is not born type person word column ring beam and roofing net shell, steel structure is of 150 m for horizontal projection diameter , the space double-deck welding ball spherical net shell of 133.06 m of span. The bicycle house roofing type world of steel structure is seen less, span Asian first, construction difficulty home initiates. Finally one promotion has adopted 24 main masts to add the 4 masts attached, 52 skeins are ground , put in the promotion persons of labor force more than 600 , promote time for 3 hours; Net shell overall promotion diameter is of 110 m , weight 460 t promotes 12 m altitude.
