High-strength subway short sleeper and preparation method thereof
The invention discloses a high-strength subway short sleeper and a preparation method thereof, and relates to the technical field of subway sleepers, the high-strength subway short sleeper comprises a steel plate base, three large steel bar frames are transversely welded to the top end of the steel plate base, and four sets of small steel bar frames are jointly welded to the inner sides of the three large steel bar frames; a concrete sleeper is poured at the top end of the steel plate base and corresponds to the large steel bar frame and the small steel bar frame, fixing holes are formed in the opposite angles of the top end of the concrete sleeper and penetrate through the bottom end of the steel plate base, sleeves are poured and fixed to the inner sides of the fixing holes, and external thread grooves are formed in the lower portions of the outer walls of the sleeves. The short sleeper has the technical effects that through the improved design, the short sleeper is obtained, the defect that the drawing force of the sleeve cannot meet the stress drawing requirement of 100kN under the condition that the size and height of the sleeper are insufficient is overcome, and the problem that tie lines cannot be normally connected due to high-low slab staggering is solved.
本发明公开了一种高强度地铁短型轨枕及其制备方法，涉及地铁轨枕技术领域，其技术要点包括钢板底座，所述钢板底座的顶端横向焊接有三条大钢筋框架，三条所述大钢筋框架的内侧共同焊接有四组小钢筋框架，所述钢板底座的顶端且与大钢筋框架和小钢筋框架对应处浇筑有混凝土台枕，混凝土台枕的顶端对角处均开设有固定孔，固定孔贯通至钢板底座的底端，所述固定孔的内侧浇筑固定有套管，套管的外壁下方开设有外螺纹槽，套管的下端螺纹套接有钢制套筒，技术效果是通过改进后的设计，获得的短制轨枕，克服了由于轨枕在尺寸高度不足的情况下，套管拉拔力不能达到100kN的应力拉拔要求，解决了因高低错台导致的联络线不能正常衔接的问题。
