大跨度装配式框架结构中心岛波浪式施工流程建造技术

Construction Technology of Wave Construction Process for Center Island of Large Span Fabricated Frame Structure

以上海地区某立体式公交停车场项目为例,结合双T板厂家生产运输能力,现场吊装专业水平,和缓凝结预应力张拉时限制订相应的施工方案。通过施工方案比较,吊装顺序及合理分块施工方案优化,波浪式施工吊装流程有效地节约了工期,为类似工程提供实践经验。

Taking a three-dimensional bus parking lot project in Shanghai as an example,combined with the production and transportation capacity of double-t-plate manufacturers,the professional level of on-site hoisting,and the limitation of the construction scheme during the tension of slow setting prestress is tensioned.Through the comparison of construction schemes,the hoisting sequence and reasonable block construction scheme optimization,the wave construction hoisting process effectively saves the construction period,and provides valuable practical experience for similar projects.
