The present invention relates to a track structure for a magnetic levitation train, and more particularly, a track structure through which the magnetic levitation train passes, and can easily adjust the position of a rail for guiding the magnetic levitation train, and when using a U-girder The present invention relates to a track structure for a maglev train configured to increase rigidity and to allow passengers to move on track in an emergency.

In general, the magnetic levitation train refers to a train that moves a vehicle on a track by using magnetic force. The support and driving guide function performed by a wheel in a general railway vehicle includes an electromagnet installed in a train and a guide installed in a track structure. It is performed by the magnetic force between the rails. Since the magnetic levitation train does not have direct contact with the rail, it has very little noise and vibration, is eco-friendly because it does not emit pollutants, and can maintain high speeds.

In particular, since the urban magnetic levitation train has a small space to be constructed in the city, it is common to install a rail so as not to be disturbed by facilities on the ground and install a rail at a considerable height from the ground. In this way, the maglev train runs on a bridge having a certain height from the ground, so if the train stops due to a breakdown during the departure from a station to the next station, the passengers who get off the train get off the train and follow the bridge. There is no choice but to walk. By the way, in the conventional track structure, it is virtually impossible for passengers to walk along the bridge, ie along the track structure, to the nearest station.

1 shows a structure of a track structure for a conventional magnetic levitation train, referring to the conventional track structure, a pier 10 supporting a lower portion and a girder 20 installed on an upper portion of the pier 10. ), A plurality of cross arms 30 provided on the upper part of the girder 20 at predetermined intervals, and a guide rail 40 formed on the cross arms 30.

In such a conventional track structure, an empty space is inevitably formed between the cross arm 30 and the cross arm 30. In an emergency in which an passenger needs to get off and move along the track structure due to a failure of the train 1, In addition to the narrow width of the structure itself, the movement of passengers is very inconvenient due to the empty space existing between the crossarm 30 and the crossarm 30. Moreover, since the track structure itself is installed at a predetermined height from the ground, passengers are afraid, especially passengers with fear of heights are unable to move unless they are provided with a separate safety facility. Therefore, despite the situation in which passengers need to move quickly, there is a problem that they cannot move quickly.

In addition, the cross arm 30 may be installed on the girder made of the I beam, in which case the cross arm 30 penetrates downward, so in the form of a bridge standing on the ground between the cross arms 30 Since all of the bottom is visible, the fear is maximized, so that there is a problem in that the cross arm 30 cannot be prepared. This problem occurs not only in case of preparation, but also in the case where a worker for maintenance passes.

In addition, the position of the guide rail is very important for the smooth running of the magnetic levitation train. In the case of using the cross arm 30 as described above, the cross arm 30 is completely fixed. The disadvantage is that it is extremely difficult to adjust.

The present invention has been invented to solve the above-mentioned conventional problems, the bottom plate is installed on the girder instead of the cross arm, and provided with guide rails on both sides of the bottom plate, passengers in the train in an emergency It is an object to be able to move safely and quickly through the bottom plate.

In addition, the present invention aims to be able to easily adjust the position of the guide rail according to the need, and in the construction of the bridge, it is an object to reinforce the rigidity of the girder even when using a U-shaped girder. .

In order to achieve the above object, in the present invention, in the construction of the track structure, a bottom plate which is continuous in the axial direction without using a cross arm installed over a width in the axial direction at regular intervals in the axial direction is used. By arranging the guide rails by using the above, the conventional problems are solved and the above objects are achieved.
