[0008] Preferably, a slot matching the limiting rod is provided on the upper surface of the limiting plate.

[0009] Preferably, an outer wall of the side wall is provided with a mounting groove.

[0010] Compared with the prior art, the embodiments of the present application have the following beneficial effects:

[0011] When installing the side wall, the side wall is placed on the station base, and the two sliders are moved away from each other by rotating the wheel, so that the limit plug rod protrudes from the outer wall of the side wall and is inserted into the limit hole on the station base, thereby fixing the side wall on the station base, and the two side walls can be assembled together by inserting the plug block on the next side wall into the slot of the previous side wall.

[0018] The embodiment of the utility model provides a station side wall connection device, such as Figure 1-3 As shown, it includes a station base 1 and a side wall 2, the left outer wall of the side wall 2 is fixedly connected with an insert block 3, and the right outer wall of the side wall 2 is provided with a slot 4 matching the insert block 3, the right outer wall of the side wall 2 is provided with a slot 4, and the slots 4 are distributed on the outer wall of the insert block 3, the upper surface of the side wall 2 is provided with an equipment slot 6, and the equipment slots 6 are distributed on the lower surface of the side wall 2, the inner wall of the equipment slot 6 is slidably connected to the limit plate 7, and the upper surface of the limit plate 7 is provided with a limit plug rod 8, the outer wall of the station base 1 is provided with a limit hole matching the limit plug rod 8, and the inner wall of the equipment slot 6 is rotatably connected with a bidirectional screw 9, the inner wall of the equipment slot 6 is slidably connected with a slider 10, and the sliders 10 are symmetrically distributed along the bidirectional screw 9, the slider 10 is threadedly connected to the bidirectional screw 9, and the upper surface of the slider 10 is hinged with one end of a support rod 11, the other end of the support rod 11 is hinged to the limit plate 7, and the outer wall of the support rod 11 is fixedly connected with a wheel disc 12.

[0019] It should be noted that, since the matching construction can reduce the amount of temporary support engineering and the consumption of building formwork, and reduce construction waste compared to the full cast-in-place construction scheme, there are few actual projects for applying it to other underground projects such as subway stations, and the disassembly and assembly of the prefabricated side walls of the station is not convenient enough. In this scheme, when installing the side wall 2, the side wall 2 is placed on the station base 1. By rotating the wheel 12, the two sliders 10 are moved away from each other, so that the limiting plug rod 8 protrudes from the outer wall of the side wall 2 and is inserted into the limiting hole on the station base 1, thereby fixing the side wall 2 on the station base 1. By inserting the plug block 3 on the next side wall 2 into the slot 4 of the previous side wall 2, the two side walls 2 can be assembled together. At this time, the pin hole 5 on the side wall 2 and the pin hole 5 on the plug block 3 coincide with each other. By inserting the pin into the overlapping pin hole 5, the plug block 3 is fixed in the slot 4, which ensures the firmness of the connection between the adjacent side walls 2. There is no need to cast in place or fix the connection with bolts, making the disassembly and assembly of the side wall 2 convenient and improving the installation efficiency of the side wall 2.

[0020] In a further preferred embodiment of the present invention, Figure 3 As shown, the outer wall of the wheel disc 12 is provided with anti-slip grooves.

[0021] In this embodiment, the anti-skid grooves increase the friction of the outer wall of the wheel disc 12 , thereby preventing a person from slipping when operating the wheel disc 12 .

[0022] In a further preferred embodiment of the present invention, Figure 2 As shown, the outer wall of the wheel disc 12 is provided with a cross groove.

[0023] In this embodiment, an external rotating rod is used, and a cross plug matching the cross groove is provided on the rotating rod. By inserting the rotating rod into the cross groove, it is convenient for personnel to rotate the wheel 12 using an external tool.

[0024] In a further preferred embodiment of the present invention, Figure 1 As shown, a slot matching the limiting rod 8 is provided on the upper surface of the limiting plate 7 .

[0025] In this embodiment, the limiting rods 8 and the limiting plates 7 are snap-fitted to facilitate adjustment of the positions and number of the limiting rods 8 .

[0026] In a further preferred embodiment of the present invention, Figure 1 As shown, a mounting groove 13 is formed on the outer wall of the side wall 2 .

[0027] In this embodiment, the installation groove 13 is a position reserved for installing wall gypsum board. By installing the gypsum board in the installation groove 13 of the adjacent side wall 2, the gypsum board can cover the gap between the two side walls 2, thereby improving the flatness between the adjacent side walls 2 and facilitating subsequent construction on the surface of the side wall 2.
