滚轧直螺纹接头在铁路桥梁工程中的应用

Application of rolled parallel thread joints of reinforcement in railway bridges engineering

滚轧直螺纹接头俗称套筒连接,以下统称套筒连接。本文通过研究套筒连接在铁路特大桥中的应用,总结了套筒连接在铁路桥梁工程中的适用条件。同时,也采用其他钢筋连接方式与套筒连接进行比较,得出套筒连接技术具有操作简便、简单易学、安全可靠、质量易控制、施工速度快、节约钢筋等特点。因此建议在铁路桥梁施工中推广使用套筒连接,但也必须注意到它的局限性。

Popular name of rolled parallel thread joints of reinforcement is Sleeve Splicing,The following called sleeve splicing.This paper researched application of sleeve splicing in a large railway bridges to summarize applicable conditions of sleeve splicing.At the same time,Compared with the other way of rebar splicing,Sleeve Splicing has the advanteges of easy operation,easy to learn,safety and reliability,quality control easy,quick speed of construction,Save bars,etc.Therefore i advise to generalize use sleeve splicing in railway bridges building,But you must pay attention to its limitations in application.
