ができる。With the rail supporting structure as described above, the following effects can be obtained. That is, in the above structure, as shown in FIG.
As shown in FIG. 5, a rail pedestal 5 for receiving the rail 2 is attached to the bottom surfaces of the vertical girders 4 and 4, and the rail 2 is mounted on it. The depth of the sleeper storage groove 51 recessed in the rail cradle 5 can be freely set. However, as shown in FIG. 6, the lower surface of the rail 2 cannot be installed below the cross beam 3. Therefore, the position of the rail 2 is determined by the upper surface of the cross beam 3. From the above, as shown in FIG. 2, the distance from the upper surface of the rail 2 to the lower surface of the cross girder 3 in the structure of the temporary railway bridge of the present invention is [rail height] + [cross girder height] is there. On the other hand, in the structure of the conventional temporary bridge for railway, as shown in Fig. 9, this is [height of cross girder] + "height of longitudinal girder" + [height of sleepers] + [height of rail]. Met. Further, in the case of FIG. 10, the stringer is in the belly of the crossing girder,
Since the girder must have a corresponding girder height, the height of the girder is limited by the height of the girder. Since the span length of the rail pedestal 5 is smaller than the span length of the vertical girder in FIG. 10, the height of the rail pedestal is lower than that of the vertical girder connected to the antinode of the transverse girder. With the above points and the cross girders shaped like boats and eliminating the wasted space below them, the structure of the present invention can significantly reduce the height from the lower end of the temporary railway bridge to the rail surface. .

It is a member configured by disposing a diagonal beam 13 between the two. The main structure 1 is formed by connecting a plurality of lower side girders 11 with a diagonal girder 13 and further connecting an upper side girder 12. At this time, as shown in FIG. 7, the lower girders 11 and the upper girders 12 have equal lengths, but at least one part of the upper girders 12 located near the center of the temporary bridge for railways is used. , The extension side girder 14 which is longer than the other upper side girders 12 is used. As a result, the upper side girder group 12 of the main structure 1
It will be longer than the group, and will be raised to the temporary bridge for railway construction. In order to prevent the railroad temporary bridge from curving downward due to the weight of the railroad temporary bridge, the climbing is given in advance to warp the railroad temporary bridge upward. As a result, it becomes possible to build the temporary railroad bridge by bending it upwards, and the temporary railroad bridge is returned to a substantially horizontal level due to its own weight (dead load). In accordance with the scale of the temporary bridge for railway constructed in this way, at least one upper side girder 12 of the main structure 1 is an extension side girder 14 whose total length is adjusted to an appropriate length, so It is possible to add appropriate climbing to the temporary railway bridge.
