Kind Code:
A
Abstract:

To disperse load to a vertical beam in a ladder type crosstie, and to increase vertical resistance force.

The ladder type crosstie is composed of vertical beams 2 installed on the lower sides of a pair of rails along the longitudinal direction of the rails respectively and made of concrete and splicing materials 3 made of steel with externally wound concrete mutually connecting these vertical beams 2 at regular intervals along the longitudinal direction of the vertical beams 2, and the concentration of train load is relaxed.
