2021-12-01
The Plastic Sleeve is made of glass fiber reinforced nylon composite material by injection molding process and has thread inside and outside. A:The inner thread matching with the spike is serrated single bevel thread,the bevel of the thread is large bevel Angle,the match between the Plastic Nylon Sleeve and the spike is a loose match,the force of the plastic sleeve and its components is better,thus greatly prolonging the service life of the Nylon Plastic Dowel and its components. B:The outer thread combined with the concrete sleeper is the thread groove with the same pitch as the inner thread.Full thread or half thread can be selected according to the different requirements of road conditions.At the same time,a transverse boss is added at both ends of the casing,and the boss is provided with an insertion hole,which is easy to insert steel bars when embedded,and improves the pull resistance of the casing to the sleeper.It can be widely used in concrete related engineering projects,such as railways,roads,Bridges,houses and so on.Especially suitable for railway sleepers,embedded in concrete turnout pillow can improve the train speed,improve the turnout speed.
