浅议体外预应力技术在现代工程改造中的应用

External Prestressing's Technology Application in Modern Construction Transformation

在现代工程结构改造中,为了完善建筑功能,形成新的大跨度空间,通过体外预应力技术实现托梁抽柱的施工工艺已经越来越多的被设计、施工单位所应用。通过对某大学教学楼会议室改造的设计理论和施工组织的研究探讨,阐明了该技术的可靠性和有效性。

In the transformation of modern engineering structures, in order to improve the building function, prestressing column joist construction process by forming new long-span space technology has been more and more applied in the design and construction. Based on the floor conference room in university teaching design theory and construction organizations, the reliability and validity of the technology are presented.
