高空悬挑现浇混凝土桁架结构的模板支撑体系及其施工

Formwork Support System and its Construction of Overhead Cantilever In-Situ Concrete Truss Structure

三亚美丽之冠大酒店工程为圣诞树建筑造型,施工中需采用现浇预应力钢筋混凝土桁架结构,呈阶梯树状错落悬挑。通过对高空悬挑现浇预应力钢筋混凝土桁架结构模板支撑体系及其施工技术的应用,顺利完成了施工,并取得良好社会效益和经济效益,为以后类似的桁架结构施工提供了可以参照的依据。

Sanya Beauty Crown Grand Hotel has its architectural modeling in shape of Christmas tree, achieved with the cast-in-place prestressed reinforced concrete truss structure overhung at random terraces of tree shape. With applications of the overhead cantilever cast-in-place concrete truss structure formwork support system and the corresponding construction technology, the construction has been successfully completed, which achieved good social and economic benefits, and can provide the basic reference for similar truss structure construction in the future.
