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. The main members used in the method of the present invention are piers, cross beams, and vertical beams.

In the construction method of the present invention, in particular, a structure in which a rail or a rail frame is integrally attached to the vertical beam 1 is used. That is, it is characterized by using a prestressed sir with a rail in which a rail or the like is integrally attached at a factory. Since the rail or the like is integrated with the vertical beam 1, the rail is simultaneously transported and erected by the transport and installation work of the vertical beam 1.
Furthermore, since the rail and the like are integrated with the vertical beam 1, it is not necessary to separately construct a track bed and the like, and the laying of the rail is completed at the same time when the installation of the vertical beam 1 is completed.

The pier 2 is also a pre-stressed member manufactured at the factory, and therefore, the construction is extremely quick as compared with the method of casting and constructing concrete on site.

A traverse beam 3 is erected. Naturally, the cross beam 3 must be fixed integrally with the upper end of the pier 2. Figure 2
As shown in the above, the intersecting steel bars are fixed with cast-in-place concrete, the PC steel material penetrating the cross beam 3 and the pier 2 is tensioned from the outside of the pier 2, or the cross beam 3 is mounted on the upper portion of the pier 2. The transverse beam 3 can be tensioned with a PC steel material exposed from the upper end of the pier 2, and other various fixing methods can be adopted.

る。<C> Installation of the vertical beam 1 On the upper portion of the cross beam 3 fixed to the upper end of the pier 2, the vertical beam 1 is installed and fixed. The rails or rail frames are directly fixed to the longitudinal beams 1 as described above. Therefore, by laying the vertical beam 1 on the upper portion of the cross beam 3, the process of laying the rail is completed integrally. After that, the crossbeam 3 and the vertical beam 1 are fixed firmly together. At the time of erection, one rail is fixed to one longitudinal beam 1. Since two longitudinal beams 1 are laid in parallel on the transverse beam 3, one set of tracks is completed.

For this purpose, for example, a sound insulating material 4 is attached to the lower surface of the longitudinal beam 1. Further, a sound absorbing material 5 such as a foam material is filled between the vertical beam 1 and the vertical beam 1 and between the vertical beam 1 and the sound insulating material 4. When the above configuration is adopted, the sound generated by the vehicle traveling above the vertical beam 1 is absorbed by the sound absorbing material 5 and further reflected by the surrounding sound insulating material 4 to prevent the sound from propagating to the surroundings. .

用できるものである。As described above, the method for constructing a railway viaduct of the present invention has the following advantages. <B> Use the one in which the longitudinal beam 1 and the rail are already integrated. 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 2, the foundation structure and other structures, the cross section can be reduced, and it is extremely economical. . <B> This is a method of assembling using members manufactured at the factory. 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> The vertical beam 1 is independently connected to the cross beam 3. Therefore, the noise of the vehicle travels widely from the space between the vertical beams 1 to the surroundings, which may be inconvenient in an urban area or the like. Therefore, in the method of the present invention, the periphery of the longitudinal beam 1 is surrounded by a material that blocks sound. Therefore, the noise of the vehicle running hardly propagates around the viaduct and can be used in a wide range.
