摘要
以浙江移动杭州分公司营业中心项目主体结构3.6m预应力梁悬挑结构为例,介绍了采用低松驰高强钢铰线解决悬挑结构的配筋问题。施工中采用性能优良的QM锚具和QMJ挤压锚具,保证了工程质量,提高了层高的净空问题,满足了项目的实际需求。
Taking the main structure prestressed beam with 3.6m long cantilever structure of the Zhejiang mobile Hangzhou branch business center project as an example, using low relaxation and high strength steel hinge line to solve some reinforcement problems of cantilever structure are introduced. It＇s indicated that using QM anchorage and QMJ ex- trusion anchorage with excellent performances can ensure the engineering quality, improve the height clearance problems and meet the needs of the project in the construction.
