[0002] A subway station is an underground facility where passengers can board, alight, transfer and wait for trains. When building a subway station, a certain space needs to be excavated first, and then the bottom slab needs to be cast. After the bottom slab is cast, the side walls need to be constructed. The side walls are composed of low side walls and upper walls. During the side wall casting process, the low side walls are cast first, and then the upper walls are cast on the low side walls to form the side walls.

[0003] Low side walls are typically constructed using formwork casting. After the low side wall formwork is set up, it needs to be supported to ensure its stability during the casting process. Traditionally, this method uses a top brace method, using steel pipes to support the formwork, forming a triangular structure with the base plate to enhance stability. However, the height of the formwork varies greatly, and traditional steel pipes are not suitable for formwork of different heights. Furthermore, they are not suitable for supporting low side wall formwork of varying curvatures, making them less suitable for use. Utility Model Content

[0017] The present invention will now be described more fully hereinafter with reference to the accompanying drawings, in which presently preferred embodiments of the present invention are shown. However, the present invention can be implemented in many different forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided for thoroughness and completeness, and will fully convey the scope of the invention to those skilled in the art.

[0018] Example 1: A stable structure for the low side wall formwork of a curved bottom plate of a subway station, such as Figures 1-4 As shown, it includes a base 1, which is trapezoidal in shape. The base 1 is trapezoidal in shape for increasing stability. A guide rail 2 is fixed to the base 1, and two electric sliders 3 are slidably connected to the guide rail 2. The guide rail 2 is used to guide the electric slider 3. The two electric sliders 3 are symmetrically arranged. A stabilizing mechanism is provided on the two electric sliders 3. The stabilizing mechanism is used to stabilize the head and tail of the template, can adapt to templates of different heights, and improve applicability.

[0019] The stabilizing mechanism includes a threaded rod 4, and the two electric sliders 3 are rotatably connected to the threaded rod 4. The electric slider 3 is used to drive the threaded rod 4 to move. The threaded rod 4 is provided with threads. The top of the electric slider 3 is fixedly connected to a guide frame 5, and the guide frame 5 is slidably connected to a sliding frame 6. The sliding frame 6 is connected to the threaded rod 4 by threads. The threaded rod 4 is used to drive the sliding frame 6 to move up and down. A contact plate 7 is fixedly connected to one side of the sliding frame 6. The threaded rod 4 drives the sliding frame 6 to move up and down, thereby driving the contact plate 7 to move up and down.

[0020] It also includes a supporting mechanism, the supporting mechanism is provided on the sliding frame 6, the supporting mechanism includes a guide frame 2 8, the guide frame 2 8 is slidably connected between the two sliding frames 6, the guide frame 2 8 is provided with a slide groove, the sliding frame 6 is connected with a bolt 9 by a thread, the upper end of the bolt 9 is located in the slide groove of the guide frame 2 8, the bolt 9 is in contact with the guide frame 2 8, the bolt 9 is used to clamp the guide frame 2 8, and a plurality of sliding seats 10 are slidably connected in the slide groove of the guide frame 2 8, and the plurality of sliding seats 10 are evenly spaced. A hydraulic push rod 11 is fixed to one side of the sliding seat 10, and the sliding seat 10 is used to drive the hydraulic push rod 11 to move horizontally, and the hydraulic push rod 11 is used to support the curved surface of the template.

[0021] Initially, the staff placed the base 1 on the curved bottom plate so that the entire device was located inside the arc of the short side wall formwork, and then aligned one of the electric sliders 3 to one side of the short side wall formwork. The staff then started the other electric slider 3 to move toward the other side of the short side wall formwork, and the other electric slider 3 moved toward the other side of the short side wall formwork, driving one of the threaded rods 4 and the guide frame 1 5 to move toward the other side of the short side wall formwork. One of the guide frames 1 5 moved toward the other side of the short side wall formwork, driving one of the sliding frames 6 to move toward the other side of the short side wall formwork. The other side of the formwork moves, driving one of the contact plates 7 to move toward the other side of the short side wall formwork. After the other electric slider 3 is aligned with the other side of the short side wall formwork, the staff stops the other electric slider 3, and then the staff rotates or reverses the threaded rod 4. Under the action of the thread on the threaded rod 4, the sliding frame 6 will move up or down, and the sliding frame 6 moves up or down, driving the contact plate 7 up or down. Then the staff pushes the base 1 to make the contact plate 7 contact with the head and tail of the short side wall formwork. Through the above operations, the head and tail of the formwork can be stabilized, which can adapt to formworks of different heights and improve applicability.

[0022] Initially, the bolt 9 clamps the guide frame 2 8. Before the electric slider 3 moves, the staff rotates the bolt 9, and the bolt 9 will move upward for a distance and disengage from the guide frame 2 8. The bolt 9 no longer clamps the guide frame 2 8, and the sliding frame 6 moves to drive the bolt 9 to move horizontally along the slide groove of the guide frame 2 8. After the electric slider 3 stops, the staff rotates the bolt 9 in the opposite direction, and the bolt 9 will move upward for a distance and re-contact with the guide frame 2 8. The bolt 9 re-clamps the guide frame 2 8, and then the staff moves the sliding seat 10 to make the hydraulic push rod 11 evenly distributed on the arc-shaped inner side of the short side wall formwork. Then the staff starts the hydraulic push rod 11, and the telescopic rod of the hydraulic push rod 11 extends. When the telescopic rod of the hydraulic push rod contacts and supports the short side wall formwork, the above operation can support short side wall formworks with different curvatures, further improving applicability.

[0023] Example 2: Based on Example 1, Figures 1-4 As shown, a rubber gasket 12 is also included. The top of the telescopic rod of the hydraulic push rod 11 is fixedly connected to the rubber gasket 12. The rubber gasket 12 is used to improve the safety of the template.

[0024] One side of the contact plate 7 is engraved with friction lines, and the friction lines on the contact plate 7 are used to increase the friction between the contact plate 7 and the template.

[0025] The rubber gasket 12 can provide a buffer during support, reduce the possibility of the hydraulic push rod 11 scratching the template, and improve the safety of the template.

[0026] The friction lines on the contact plate 7 are used to increase the friction between the contact plate 7 and the template, making the support more stable.

[0027] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention and are not intended to limit the scope of protection of the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solution of the present invention may be modified or replaced by equivalents without departing from the essence and scope of the technical solution of the present invention.
