PROBLEM TO BE SOLVED: To provide a sole plate for laying a raceway surface, having a high degree of freedom of the installation positions of fastening elements to a sleeper, and a laying structure thereof.SOLUTION: A sole plate 10b for laying a raceway surface is laid astride two sleepers 2, and has a body part 11 and a connection part 12. The connection part 12 can be connected with a junction part 15 of a sole plate 10a for laying the raceway surface. The average thickness of a joint portion of the connection part 12 of the sole plate 10b for laying the raceway surface is smaller than the average thickness of the body part 11. In a junction state, an overlapping part 30 between the connection parts 15, 12 forms a lamination layer structure positioned on the sleeper 2 and laminated in the thickness direction, and a fastening element 3 is inserted into the overlapping part 30 and fixed to the sleeper 2. |
