[0023] In order to further illustrate the present invention, the following describes the present invention in detail with reference to the accompanying drawings and embodiments, but they should not be understood as limiting the protection scope of the present invention.
[0024] Such as figure 1 As shown, the present invention is a π-type track beam applied to a beam on a large-span high-speed maglev line, comprising a π-type track beam 1, an adjustable support 6 and a load-bearing box beam. The π-type track beam 1 and the The load-bearing box girder is connected by the adjustable support 6 to form a long-span rail girder structure. The load-bearing box girder adopts a single-line track or a double-line or multi-line track. Such as Figure 6-8 As shown, the π-shaped track beam 1 is mainly composed of a π-shaped beam main body 4 and a π-shaped beam support 5. The π-shaped beam main body 4 is a longitudinally extending three-dimensional π-shaped beam, with flanges extending from th...
