する位置のカーブに応じた円弧状に形成する。<A> Vertical Beam In the present invention, a beam installed in a direction parallel to a railroad track is referred to as a vertical beam 1. The longitudinal beam 1 of the present invention is a precast member made of prestressed concrete manufactured at a factory. Therefore, components manufactured under good quality control can be used. No rails or the like are attached to the surface of the longitudinal beam 1 and it is configured as a simple long block. The planar shape of the longitudinal beam 1 is a straight line in FIG. 1, but is generally formed in an arc shape corresponding to a curve at the installation position.

The block 4 is a concrete arc-shaped long member having the same area as the upper surface of the vertical beam 1 and is formed at a height calculated especially. Since the left and right wheels of a railway vehicle are fixed integrally by an axle, the left and right wheels must pass through a curve while rotating at the same speed. For this purpose, it is necessary to form a gradient on the tread surface of the wheel, and to widen the interval (slack) and change the height of the right and left sides (cant) of the rail at the curved portion. Among them, the spacer block 4 is interposed between the longitudinal beam 1 and the rail for the purpose of obtaining a cant.

Rails and the like are integrally attached to the upper surface of the concrete sleeper 5 at a factory using a fastening device. Rails and other sleepers 5
Since the rails are integrated, the rails can be simultaneously transported and erected by transporting and erection work of the vertical sleeper 5. In the curved portion, it is necessary to change the contact position between the tread surface of the wheel and the rail surface by extending the gauge inside the circular curve. Therefore, when fixing the rail to the vertical sleeper 5,
The rail inside the curve must be fixed in the correct position as calculated. Since this fixing work is also performed in a well-managed factory, it can be reliably fixed at an accurate position.

Therefore, components manufactured under good quality control can be used. Furthermore, each concrete member uses a prestressed one. Therefore, sufficient strength can be expected while being lightweight with a small cross section.

This pier is also a pre-stressed member manufactured at the factory, and therefore its construction is extremely quick as compared with the method of casting and constructing concrete on site.

This crossbeam must, of course, be fixed integrally with the upper end of the pier. For this purpose, crossing steel bars are fixed with cast-in-place concrete, PC steel penetrating the cross beam and the pier is tensioned from the outside of the pier, or the cross beam is mounted on the top of the pier and exposed from the upper end of the pier. P
The transverse beam can be tensioned with C steel, and various other fixing methods can be adopted.

The longitudinal beam 1 is a simple concrete beam as described above, and is firmly fixed directly to the transverse beam. At the time of erection, since the vertical swords 1 are independent for each one, two vertical swords 1 are laid in parallel on the cross beam.

を低減することができる。As described above, the structure of the vertical bridge 1 of the railway viaduct of the present invention has the following effects. <A> A trajectory is constituted by the longitudinal beam 1 and the rail. Therefore, construction of the slab is not required, and a large amount of roadbed mounted on the slab is not required. Therefore, the dead load can be greatly reduced, and as a result, the horizontal inertia force at the time of the earthquake is reduced, so that the cross section of the pier, the foundation structure and other structures and the cross section can be reduced, which is extremely economical. <B> Components manufactured at the factory and assembled using these. Therefore, the number of parts and members is smaller than that of a method in which concrete is cast by assembling a formwork on site, and the construction period can be greatly reduced. <C> Since a beam and a fixed beam are used without using a cast-in-place slab, there is no need to support a slab formwork or the like. Therefore, even when the construction is performed on the upper part of the railway in use, the height can be reduced by the height of the support and the formwork, and economic construction is possible. <D> Only the longitudinal beam 1 of the present invention is erected in the air. Therefore, unlike the conventional slab structure, rain and snow do not accumulate and the processing is simple. <E> A structure in which a block 4 for adjusting the height is interposed between the longitudinal beam 1 and the rail. Therefore, cants and slacks in the curve can be accurately set, and no special maintenance is required for maintaining the dimensions thereafter, and the management cost can be reduced.
