PROBLEM TO BE SOLVED: To prevent the occurrence of deviation in a rail and a vertical beam, to reduce the oscillation and vibrations of a car and to provide a comfortable ride.
SOLUTION: A sleeper projection 3 protected to the inside or the outside is formed integrally at one place excepting a center in the longitudinal direction of the internal side face or external side face of the vertical beam 2 for a rail supporter 1. The rail supporter 1 is laid on a roadbed 21 under the state in which cushioning materials 25 and 26, a vibration-proof material 23 and a void material 27 are installed, the rail 30 is mounted on the rail supporter 1 and concrete is placed to sections as a horizontal stopper 24 and a base 22. The vibration-proof material 23 or the cushioning materials 25 and 26 are interposed between the vertical beam 2 and the roadbed 21, between the horizontal stopper 24 and the vertical beam 2 and between the horizontal stopper 24 and the sleeper projection 2. Impulses and vibrations from the vertical direction, the rail direction or the rail orthogonal direction are damped and absorbed by the vibration-proof material 23 or the cushioning materials 25 and 26, the deviation of the vertical beam 2 and the rail 30 is prevented and the oscillation and vibrations of the car are reduced.
