CONNECTING STRUCTURE OF SYNTHETIC SLEEPER
Document Type and Number:
Japanese Patent JP2002275805
Kind Code:
A
Abstract:

To provide a connecting structure of a synthetic sleeper for constituting a long size branch sleeper.

This connecting structure of the synthetic sleeper is connected by butting and adhering lengthwise directional end parts of two or more synthetic sleepers 1a and 1b. The mutual connecting end parts of the sleepers are mutually formed as complementary-shaped connecting parts 2a and 2b. The connecting parts are composed of a finger work part having the prescribed length in the sleeper lengthwise direction, and having a plurality of double helical projection parts 6 extending in the width direction of the sleepers. A reinforcing member 3a longer than the connecting parts is arranged on at least one surface of an upper surface, an under surface or front and rear side surfaces of the synthetic sleeper so as to cover the connecting parts 2a and 2b of the synthetic sleeper. The reinforcing member is adhered and joined to a surface of both synthetic sleepers. Reinforcing pins 4 and 5 are driven to obtain flexural strength of a certain degree from the initial stage of adhesion.
