摘　　要：利用自身建筑物顶部结构作张拉墩,在高空进行预应力筋张拉、混凝土浇筑、预应力筋放张。该技术可以提高工作效率,降低劳动强度,降低工程成本,而且不受场地限制,能充分利用多种机械进行机械化施工,施工进度快,减少了预制、运输和吊装带来的技术和质量问题,结构整体性好。Roof structue of the building being utilized for tensioning construction, pre-tensioning and concrete pouring as well as release of the tensioning bar were carried out high in the air. This technology may improve work efficiency, reduce laboring strength and cut down costs. Being not restricted by site conditions, it could also make full use of construction machines to speed up the construction, and reduce the technical and quality problems caused by pre-fabrication, transportation and installation. The structure therefore had a good integrity.
