Claims

[Claims for Utility Model Registration] (1) The overall shape is formed into a substantially rectangular parallelepiped, and mounting and engaging portions are formed at the upper corner portions of the sides that substantially intersect with the longitudinal direction, and are installed at predetermined intervals. Both ends engage with the mounting engagement portions of the sleeper bodies that are formed of concrete or the like and are opposed to a large number of sleeper bodies;
and a tread material laid parallel to the upper surface of the sleeper main body by being supported, and characterized in that the sleeper main body and the tread material are laid in combination. Simple roadbed material. (2) The mounting engagement portions of the sleeper main body, in which both ends of the tread plate material are engaged and supported, are notches provided at regular intervals on the left and right in the upper corners of both sides intersecting the longitudinal direction of the sleeper main body. The simple roadbed material for ridge roads according to claim 1, characterized in that it has a concave portion. (3) The simple roadbed material for a ridge road according to claim 1, characterized in that at least the surface of the step board material is appropriately provided with anti-slip means. (4) The length of the tread material placed on the outer circumference side of the tread plate material at the route change section that connects to a straight section of a soft road surface is longer than the length of the tread board material on the inner circumference side, along the curvature of the course change section. The inner and outer ends of the tread plate material are formed so that they can be freely engaged with and detached from attachment engagement parts provided on the side surfaces intersecting the longitudinal direction of the terminal sleeper body, which are arranged at regular intervals in the straight line part. 1. A simple roadbed material for a ridge at a route change section, characterized by forming an inclined notch with a desired angle.
