Claims

[Scope of claim for utility model registration] (1) A tubular rail in which the upper end of a support pile embedded in the ground and a tubular rail are connected by a joint, and the tubular rail is supported at a constant height above the ground. In the installation structure, (a) an adjuster star cap 2 having a connector 3 at the upper end is fitted into the upper end of the support pile 1; The joint 5 is provided with a connector 6 on its lower surface, and the connector 6 is tiltably connected to the connector 3 of the adjuster star cap 2, and the rail receiver 7 has a plurality of engagements in the rail axis direction. A stop part 8 is formed, and c) the tubular rails 14 are connected in series by an inner joint 9 which is fitted into the mouth of the connecting end in an interference fit, and the inner joint 9 It is characterized by having a flange portion 20 having approximately the same diameter as the outer diameter of the tubular rail 14 on the outer periphery of the central portion in the longitudinal direction, and a locking portion 10 that is engaged with the locking portion 8 of the rail receiver 7. Laying structure of tubular rail. (2) The locking part 8 of the rail receiver 7 is connected to the tubular rail 1
The locking groove 10 of the inner joint 9 is a locking groove formed at a predetermined pitch in the axial direction of the rail receiver 7 and at a constant depth in the circumferential direction from the mouth edge of the rail receiver 7. 20. A tubular rail laying structure as set forth in claim 1 of the utility model registration claim, characterized in that the key protrusion is protruded as an extension of the tubular rail.
