The composition and description of the components of the elastic strip SKL fastener

The spring V-shaped fastener (hereinafter referred to as the fastener) is composed of a spring, a pre-embedded iron seat, an insulating gauge block and a rubber backing plate.
1. Spring bars
When laying, you need to choose the appropriate elastic strips. And match with different insulating gauge blocks
1. Embedded iron seat
This part is pre-embedded in the sleeper, and the embedding accuracy should meet the size requirements in the figure below.
1. Insulated gauge block
There are two types of insulating gauge blocks (hereinafter referred to as gauge blocks). Except for the non-black gauge blocks of No. 7, No. 8 and No. 9 joints, other gauge blocks are black.
