Here, the monorail track beam structure includes a track beam, track beam support, anchor case, pier and the like.

A monorail is a means of transporting a vehicle over or under suspension on one track (orbital beam) to move passengers and cargo. The monorail is a small rail, track bus, maglev train, and the like. It is emerging as a new urban means of transportation, and it is a public transportation that belongs to the category of light rail, which is a concept opposite to a heavy subway such as an existing subway.

These monorails have excellent transport capacity, low construction and labor costs due to the intermediate transportation capacity between subways and buses. Especially, they run with rubber wheels, so there is no noise and vibration. Has the advantage. In addition, the use of land can be increased to create a three-dimensional and beautiful urban landscape, so the use is already high in Europe and Japan.

The monorail structure is characterized by a structure that does not require an upper slab because a wheel that runs as a single track beam is driven above the track beam. In addition, such a monolane is a means of transportation that can be applied to downtown areas with high population density and narrow road widths and dense urban areas. At this time, the monorail requires a precise construction because the structure is a direct track. In other words, the structure of the monorail is simple in appearance, but since the direct vehicle runs in the structure, a structure having a smooth surface and matching linearity must be constructed, and it must be manufactured and hypothesized precisely.

First, it receives the load acting on the upper structure between the bridge piers and the track beam, which is the upper structure, and the endurance life of the monorail by accommodating the relative displacement caused by vehicle load or temperature change and the shear displacement acting horizontally (the direction of the bridge). At least one orbital beam support is installed in order to extend.

The orbital beam support may be composed of a fixed end (fixed support) and a movable end (movable support) 200 shown in FIG. 7.

The fixed end is a type of hinge, which transmits vertical and horizontal reactions but does not transmit bending moments because it is free to rotate. At this time, the rotating mechanism includes rolling (line bearing, pivot bearing), sliding (pin bearing, spherical bearing), elastic deformation (elastic bearing, pot bearing).

The movable stage 200 transmits only the vertical reaction force and moves freely with respect to the horizontal and the rotation. Mechanisms of horizontal movement include rolling (roller bearings), sliding (plane bearings, line bearings, port bearings), shear elastic deformation (elastic bearings), and the like. Even in the case of the movable end 200, a slight horizontal resistance force is generated by friction during horizontal movement. At this time, the friction coefficient is one of important factors to be considered in the design.

In addition, when the orbital beam support is a fixed end, there is no horizontal movement amount and thus does not cause shear deformation. However, when the orbital beam support is a one-way movable end, the orbital beam support accommodates expansion and rotation while causing shear deformation and rotational deformation according to the horizontal movement amount.
