The Fatigue Research of Straight Thread Sleeve Connection for Beijing South Railway Station

Abstract:

As for Beijing South Railway Station, railway track just lies on the roof slab of the basement, in railroad bridge or the railroad station orbit layer structure, the reinforcing bar designs general is used thick diameter reinforcing bar.However weld can’t assure the quality, and the reinforcing bar is dense, it is hard to site operation;But the mechanical connection has many advantages, such as have high quality, convenient construction,high productivity ,so now more and more project will choose it.Railroad station orbit layer has a total of 500 000 steel bar joints inside and directly bears the live load of moving trains,which need to do a fatigue search for assuring its satisfy use and specification request.Finally,through the test and application,the result is very good, gives reference for other construction projects of machinery connectivity on the live load.
