[0025] The bottom end of the vertical support rod 8 is fixed with a track pulley 11 by bolts or pins, and the track pulley 11 is located on the tool rail 4 fixed on the ground.

[0026] The top of the triangular truss 10 is fixed with an integral thermal insulation tarpaulin 5, and the four corners of the tarpaulin 5 are respectively fixed to the bottom ends of the four vertical support rods 8 of the two sets of support frames 9 by wires. In this embodiment, the entire shed adopts a closed design, which is tightly sealed on all sides, has a good thermal insulation effect, and can significantly improve the thermal insulation and curing effect of the concrete of the track bed slab in winter. The entire shed structure is lightweight, easy to push and move, and only one person is needed to realize the change of work area, which greatly reduces the labor intensity of the workers. The entire shed movement and installation process is simple and quick, without the need for complicated equipment and a large amount of manpower, which can significantly improve construction efficiency and shorten the construction period. In this embodiment, the connecting parts of each section of the triangular truss 10 are made of lightweight and durable round tubes with a diameter and thickness of 50mm and 1.5mm, respectively.
