摘要
以武汉商业服务学院体育馆预应力框架和柱预应力混凝土施工为例,着重介绍了该工程预应力梁跨度大、预应力筋单孔束数多且长、张拉用千斤顶吨位大、预应力柱及部分预应力梁为变角度张拉和张拉端节点复杂等施工难点的解决措施,为后张有粘结预应力混凝土施工提供了参考。
Prestressed concrete frame and column construction of Wuhan Commercial Service College Gym- nasium is taken as an example herein to introduce measures that are adopted to solve construction difficulties in details, such as large span of prestressed beam, many long prestressed steel single pore bundle, high tonnage of prestressing hoisting jack, variable prestressing angle of prestressed column and partial prestressed beam and complex prestressing end nodes, providing references for post-tensioning bonded prestressed concrete construction.
