本考案では、軌道の橋絡部に作用する外力は、曲線部の
撓み変形により吸収される。In the present invention, the external force acting on the bridge portion of the track is absorbed by the bending deformation of the curved portion.
以下、本考案の一実施例を図面を参照して説明する。 An embodiment of the present invention will be described below with reference to the drawings.

Ｂ上で曲線部10Cを支持している。In FIG. 1, 10 is a rail of the bridge portion 7 (horizontal rail).
And has a shape having a curved portion 10C between the right and left straight portions 10A and 10B, and is connected to the rail 1 extending in the building A, while the straight portion 10A is fixed to the building A by the support legs 6. , The other straight portion 10B connected to the rail 1 extending in the building B is fixed to the building B by the support leg 6B, and the curved portion 10C is the movable support leg 1
It is supported by 1A and 11B. This movable support leg 11A has a second
As shown in the figure, it has an inverted L shape with a horizontally oriented rail support arm M, a free wheel 12 is attached to the lower end of the leg, and it stands on a rolling plate 13 fixed to the building A. is doing. The movable support leg 11B also has a similar structure. Movable support leg 11A
Supports the curved portion 10C on the building A, and the movable support leg 11B supports the curved portion 10C on the building B.

力Fxは該頂部で最小となる。レール10はレール１と同じ
断面形状を有する薄板の長手部材であるからレール板幅

縮力および引張り力を吸収する。In this configuration, when the buildings A and B shake in the direction of the arrow shown in the figure due to an earthquake, tensile and compressive forces in the directions indicated by the broken line arrows act on the straight horizontal portions 10A and 10B of the bridging portion 7, and the curved portion 10
An X-direction component force indicated by Fx and a Y-direction component force indicated by Fy act on C. The component force Fy becomes maximum at the top of the curved portion 10C, and the component force Fx becomes minimum at the top. Since the rail 10 is a thin plate longitudinal member having the same cross-sectional shape as the rail 1, it has flexibility in the rail plate width direction, and the curved portion 10C has a movable support leg 1
Since it is freely supported by 1A and 11B, the curved portion 10C bends when it receives the above-mentioned component forces Fx and Fy, and when the force acting on the bridge portion 7 is a tensile force, it is compressed into a flatter shape. In the case of a force, it is elastically deformed more smoothly in a mountain shape and absorbs the compressive force and the tensile force.

The rail 14 of the bridge portion 7 is laid on the rail 1 laid on the first floor of the building B and on the second floor of the building A. Bridge with the rail 1. This rail 14 has an upper curved portion 15 continuous with the linear portion 14A, a lower curved portion 17 continuous with the linear portion 14B, and a vertical linear portion 16 continuous with both curved portions between the linear portions 14A and 14B at the left and right ends. It has a structure having, and the linear portion 14A is connected to the rail 1 extending in the building A, while the straight portion 14A is supported by the building 6
The other straight portion 14B fixed to the building B and connected to the rail 1 extending into the building B is fixed to the building B by the support legs 6.

きる。As described above, the present invention utilizes the flexibility of the rail of the track in the rail width direction, and supports the building and the bridge spanning the building with a curved portion so that the curvature can be changed. The force acting on the track due to the difference in the vibration phenomena of both buildings can be absorbed by the curved part, preventing the occurrence of a situation where the carriage is unable to run due to the track being damaged due to an earthquake or the like. The reliability can be improved as compared with the conventional one.
