Abstract

本实用新型公开了一种置于轨枕座下的混凝土轨枕枕下用多层垫板,包括都制有沟槽的顶面和底面,其主要由上层垫板(1)与下层垫板(2)相互连接而成,下层垫板底面沟槽(3)的槽口宽度为20~60mm;由于本实用新型的上层垫板(1)专门解决静刚度问题,下层垫板(2)以及下层垫板底面沟槽(3)的槽口宽度为20~60mm是专门解决匹配和适应粒度在20~60mm之间的、不规则的、带有锋利棱边及尖角的道碴问题;因此本实用新型能够将性能优异的不同材料组合在一起、实行强强联合,从而取得更好的综合性能。
The utility model discloses a multi-layer tie plate which is arranged below a sleeper seat and used below a concrete sleeper. The multi-layer tie plate comprises top surfaces and bottom surfaces with trenches and is mainly formed by mutually connecting an upper layer die plate (1) and a lower layer die plate (2), and the width of a rebate of the trench (3) of the bottom surface of the lower layer tie plate is 20-60mm. The upper layer tie plate (1) of the utility model specially solves the static rigidity problem, while the lower layer tie plate (1) and the width of the situation that the rebate of the trench (3) of the bottom surface of the lower layer tie plate is 20-60mm specially solve the problem of matching and adapting to irregular ballast with particle size of 20-60mm and sharp edges and sharp corners, so that the multi-layer tie plate can combine different materials with excellent performances together, realize the win-win combination and further obtain better comprehensive performance.
