体育场大跨度异形管桁架结构现场整体拼装技术

FIELD INTEGRATION TECHNOLOGY OF LARGE SPAN SPECIAL-SHAPED TUBE TRUSS STRUCTURE IN STADIUM PROJECT

某体育场看台大跨度异形管桁架罩棚、长度大、悬挑跨度大、采用现场整体拼装技术,施工中对拼装场地地面进行加固处理,制作异形管桁架胎架应用BIM技术指导桁架拼装及吊装,保证了异形管桁架的安装质量.

Wide-span specially-shaped tube truss canopy was used for a stadium grandstand in Beijing. It is long and with large cantilever span, so on-site integral assembly technique was adopted. During construction, the ground for assembly was strengthened, specially-shaped tube truss jig was made and BIM technique was used to guide the truss assembly and lifting and to guarantee the installation quality of the specially-shaped tube truss.
