いためである。In the present invention, when carrying the bearing device 5 into the filed recess 15, the bearing device 5 is first moved in the direction perpendicular to the bridge axis by the hanging transport frame 38 that moves along the guide rail 26. 15 to the front side of the opening, and then the bearing device 5 is moved in the direction of the bridge axis by the carriage 40 with a lifting platform that moves along the rail 46, and is stored and moved in the deep portion inside the filet recess 15. The reason why the bearing device 5 is moved by the movement in two perpendicular directions is as follows. That is, the filet recess 15 has a substantially U-shape when viewed from a plane, and its opening is in the bridge axis direction (that is,
(In the middle of the bridge girder), and a temporary receiving jack base 8 and a temporary receiving jack 12 supported by the mounting stand are present in the direction perpendicular to the bridge axis of the filet recess 15, so that the temporary receiving jack base 8 is provided. This is because the support device 5 cannot be carried in only by one-way movement from the direction perpendicular to the bridge axis.

実用上すぐれた効果がある。As described above, according to the present invention, when exchanging old and new bearings at the upper part of the abutment, a heavy-weight bearing device is suspended from the upper part of the bridge girder at a position substantially at the same height as the upper part of the abutment. , Mounted on a suspended transport frame that travels along the rail, and the suspended transport frame stops moving to the position in front of the opening of the filet recess where the new bearing device is to be installed, that is, the position on the side in the bridge axis direction. Then, at this position, it intersects with the runway of the suspended transport frame, travels in the direction of the bridge axis at right angles to this, and moves on a carriage with a lift platform that travels along a rail extending to the inside of the recess. By moving this bogie forward, the new bearing device can be carried into the narrow installation space above the abutment and the underside of the bridge girder, so that it is possible to carry the bearing device quickly and safely with a small number of operators and quickly and safely according to the manual. Excellent effect in practical use There is.

入方法。Claims: 1. Installed between an abutment upper surface and a bridge girder lower surface,
A method of carrying a bearing device supporting the bridge girder onto the upper surface of the abutment, wherein a guide rail extending in a direction perpendicular to the bridge axis through a lower surface of the bridge girder is provided by being supported on a side wall of the bridge girder and an upper slab side wall. A supporting device with a base plate is suspended from above on a suspended transport frame suspended via a trolley traveling along the guide rail, and the suspended transport frame is mounted on an abutment. It is moved to the front of the opening located in the axial direction, temporarily stopped, and then disposed in the bridge axis direction so as to intersect with the runway of the suspended transport frame, and the tip extends along the bottom surface of the filet recess and extends therefrom. The bearing device with the base plate is mounted on a lift platform of a bogie equipped with an elevator that travels along a rail that reaches the rail, and the bogie is moved to the shearing recess, and then anchored to the underside of the bridge girder. The upper part of the support device supported by the lift is fixed to a sole plate previously attached via a bolt via bolts, and then the lift is lowered to move the bogie out of the filer recess, and An abutment for a bearing device, comprising: removing a rail from a concave portion; and then filling the filling concave portion with filling concrete so that a lower anchor bolt temporarily supported on a base plate attached to the bearing device is embedded. How to carry in to the upper part.
