大跨度后张曲线预应力现浇框架梁的施工工艺

Construction Technology of Cast-in-place Roof Beams of Frame with Large Span and the BehindTension Curve Pre-stressed Force

安阳某多层厂房的框架梁采用了后张曲线预应力混凝土结构,本文介绍了波纹管曲线放样、钢绞线编束、波纹管就位固定、钢绞线束张拉等工序的施工工艺,同时对曲线预应力选材进行了对比分析。

The roof beams of frame of some multi - layer workshops in Anyang City are concrete structure of the behind tension curve pre - stressed force. It involves construction technology of working procedure ： the curve lofting of corrugated pipes, the steel stranded wire arranged ties, fixing of the corrugated pipes, tension of the steel wires the and so on, at the same time, selected materials with the curve pre - stressed force should be paid attention to.
