Claims (1)

[Claims for Utility Model Registration] Contact surfaces 11a, 11a extending in the sleeper width direction and parallel to each other are formed at both ends of the floor plate receiving recess 11 extending in the longitudinal direction of the concrete sleeper 1, and a sliding surface parallel to the contact surfaces. 42a, and sets the position in the width direction of the sleeper by sliding the sliding surface 42a on the contact surface 11a; and a second fastening fitting 5 for fixing the directional position,
The gauge can be adjusted by moving the floor plate 2 in the longitudinal direction of the sleepers, and the fastening bolts 3 are screwed into the embedded plugs 12 buried near both ends of the floor plate receiving recess 11 to connect the first fastening fittings 4 and the first fastening fittings 4. 2. A structure for fastening a floor board to a concrete sleeper, characterized in that the floor board 2 is fastened to the concrete sleeper 1 by connecting two fastening fittings 5. The first fastening fitting has an L-shaped cross section consisting of a flat part 41 extending along the upper surface of the end of the floorboard 2 and a vertical part 42 extending along the side surface of the end, and is attached to the upper surface of the flat part 41 in the width direction of the floorboard. A plurality of parallel carved grooves 41a and a long hole 41 extending in the width direction of the floorboard
b, the vertical portion 42 has a thickness that increases in the floorboard width direction along the edge of the floorboard receiving recess 11, and the second fastening fitting 5 is attached to the lower surface 51 of the first fitting 4. It has a similar parallel carved groove 51a that meshes with the upper surface parallel groove 41a of the flat part 41, and has a round hole 52a through which the fastening bolt 3 is inserted, and the flange part 61 that comes into contact with the upper surface 52 of the second member 5 and the above-mentioned. The insulating member 6 includes a cylindrical portion 62 that is inserted from the insertion hole 52a of the second member 5 into the elongated hole 41b of the first member 4, and after adjusting the first metal fitting 4 in the floorboard width direction, 2 metal fittings 5 are placed, and the width direction position with respect to the floor plate 2 is set by the mutually meshing parallel grooves 41a, 51a, while the fastening bolt 3 is insulated and screwed into the embedded plug 12 with respect to the floor plate 2 by the insulating member 6. A fastening structure for concrete sleepers, characterized in that a floor plate 2 is fixed together.
