长沙冰雪世界巨型多截面预应力钢筋混凝土梁叠合法施工技术
Superposition Technology of Huge Super Multi Section Prestressed Reinforced Concrete Beam in Changsha Ice and Snow World
【摘要】 详细阐述了混凝土叠合法浇筑的特点、施工工艺及梁下部支撑体系的设计处理。从现场混凝土浇筑效果来看,叠合法施工技术在保证足够安全储备的前提下,能有效减少下部临时支撑体系的投入,提高了现场模板的周转效率,降低了项目成本。
【Abstract】 The characteristics, construction technology, the design and treatment of the supporting system of the lower beam are described in detail. From the effect of on-site concrete placement, superposition construction technology can effectively reduce the investment of temporary support system under the premise of ensuring enough safety reserve, improve the turnover efficiency of field formworks, and reduce the cost of projects.
