摘要： PURPOSE: To increase lateral resistance by fixing and suspending bearing plates having length, in which both ends are abutted against the end faces of adjacent sleepers in a rail turnout section, etc., to the lower sections of the end faces of adjacent sleepers through fittings. CONSTITUTION: The upper ends of bearing plates 11 are brought into press- contact among the vertical sections 18 of fittings 15, to which the bearing plates 11 are fitted, and the end faces 13 of sleepers 12. The horizontal sections 17 of the fittings 15 are fixed onto the top faces 16 of the sleepers 12 by screw spikes 21. Flanges 19 for reinforcement are formed on one sides of the vertical sections 18 while being bent to the outside, thus increasing the rigidity of the fittings 15. Accordingly, lateral load can be transmitted to the deepest sections of the bearing plates while the tendency of the overturn of the bearing plates can be prevented, and the lateral resistance of a device is augmented and the buckling of a rail can be obviated.

摘要： PURPOSE:To connect exremely easily two fittings to each other without using any tools by providing oblong like bolt inserting holes in the fittings while making the axial length of a connecting bolt about two times the thickness of the fittings and forming a rotation blocking part of a square or the like on the proximal part and a locking part on the tip of the connecting bolt. CONSTITUTION:A connecting bolt 13 is inserted into bolt inserting hole 17 in one buckling preventing fitting 11. After a locking part 18 formed on the tip of the bolt 13 is rotated to be orthogonal to the bolt inserting hole 17, a rotation blocking part 133 is fitted in the inserting hole 17. Next, the other buckling preventing fitting 11 is overlaid on one buckling preventing fitting 11 orthogonally thereto. After the locking part 18 of the connecting bolt 13 is fitted in the bolt inserting hole 17, the buckling preventing fitting 11 is rotated to be located parallel to one buckling preventing fitting 11. Thus, the two buckling preventing fittings 11 superimposed on each other are sandwiched by a head 132 and the locking part 18 of the connecting bolt 13 to be held under the connected condition.

摘要： PROBLEM TO BE SOLVED: To prevent a fall of the wheel of a bicycle in a gap by a method wherein a zigzagging auxiliary device of a belt-like elastic material fitted in the upper surface of a protection material of an elastic material is embedded in a gap between the main rail of a railroad crossing and a guard rail. SOLUTION: A fit-in groove 9 having an opening part narrower than a groove width is formed of an elastic material along the longitudinal direction of an upper surface to form a protection material 6. Further, a protection material auxiliary device 7 having a fit-in piece 10 for pull-out prevention formed approximately the same sectional shape as that of a fitting-in groove 9 of a protection material 6 and provided at two ends with engaging stepped parts 11 are a fit-in piece 10 for pull-out prevention are formed on the under surface of an auxiliary device body 8 formed of a belt-like elastic material and narrower than a gap 5 between a main rail 1 and a guard rail 2 of a railroad crossing part and formed in a zigzagging state. The protection material 6 is mounted on the lower part of a gap 5 of the railroad crossing part, a fit-in piece 10 of a protection material auxiliary device 7 is pressed in from the side of the fit-in groove 9 for fitting-in, and the adjoining protection material auxiliary devices 7 are connected to each other through the engaging stepped part 11. The protection material auxiliary device 7 completely fills the gap without disturbing the passage of a train and prevents a fall of the wheel of a bicycle and a wheelchair.
