预应力混凝土柱的施工技术

Construction Technology of Prestressed Concrete Column

随着建筑体量的不断增大,建筑工程对混凝土的质量和性能要求也不断增大,为了满足大跨度小截面构件的需求,预应力技术开始不断发展。本工程中采用的偏心受压预应力混凝土柱的技术,在柱的强度方面得到增强,截面减小,节约能耗,同时提高了混凝土的抗裂性能。通过预应力柱的施工技术有效控制截面,解决柱根部的裂缝问题。

With the increasing volume of building,the quality and performance requirement of concrete is increasing.In order to meet the needs of large-span and small section members,the technology of prestressed concrete is developing constantly.The technology of prestressed column adopted in this project has been reinforced in the strength of columns, reducing the section,saving energy and improving the crack resistance of concrete.Through the construction technology of the prestressed column,the cross section can be effectively controlled to solve the crack problem at the root of the column.
