[0038] Reference Figure 2Specifically, the upper connecting ring 2 is welded and fixed to the circular column body 1, and a plurality of ribs 3 are welded and connected to the circular column body 1. The upper connecting ring 2 is connected to the roof support structure of the underground first floor of the subway hub station, which effectively increases the bearing surface area. The plurality of ribs 3 decompose the weight borne by the upper connecting ring 2 and evenly distribute it on the top of the circular column body 1 to avoid the occurrence of excessive load concentration.

At the same time, several auxiliary connecting plates 6 can play a role of pre-positioning in the process of connecting the lower end of the circular column body 1, which is convenient for the alignment connection of the circular column body 1. After the connection is completed, the auxiliary connecting plates 6 can play a good structural reinforcement role, effectively improve the overall structural strength of the super-high load-bearing steel column structure of the subway station, and meet the super-high load-bearing requirements of the subway hub site.

[0042] Reference Figure 1 and Figure 4The middle section of the super-high load-bearing steel column structure of the subway station is provided with a plurality of connecting frames 7 for connecting with the cross beams. One end of the connecting frame 7 is fixedly connected to the outer side surface of the circular column body 1. The connecting frame 7 includes an upper extension plate 71, a lower extension plate 72 and a web 73. The upper extension plate 71 and the lower extension plate 72 are arranged alternately up and down and parallel to each other. The web 73 is connected between the upper extension plate 71 and the lower extension plate 72 and is perpendicular to the upper extension plate 71 and the lower extension plate 72 respectively.

[0043] Reference Figure 1 and Figure 4 The middle section of the super-high load-bearing steel column structure of the subway station is provided with at least two annular rib plates 8 arranged alternately up and down, the inner circle of the annular rib plates 8 is fixedly connected to the circular column body 1, one end of the upper extension plate 71 and one end of the lower extension plate 72 are respectively fixedly connected to the edges of the corresponding annular rib plates 8, the web 73 extends toward one end of the circular column body 1 to between the two annular rib plates 8 and is fixedly connected to the two annular rib plates 8, and the extending end of the web 73 is fixedly connected to the outer side surface of the circular column body 1.

[0044] Reference Figure 1 The end of the web 73 away from the circular column body 1 is provided with a plurality of first cross beam connecting holes 731 .

[0045] Reference Figure 5 Two groups of steel beam connection components 9 are arranged between the upper extension plate 71 and the lower extension plate 72. The two groups of steel beam connection components 9 are symmetrically arranged relative to the web plate 73. The steel beam connection components 9 include a steel beam connection plate 91, a wing plate 92 and an overload collapse plate 93. The wing plate 92 is vertically fixed to the side of the web plate 73, and the wing plate 92 is parallel to the upper extension plate 71 and the lower extension plate 72. The steel beam connection plate 91 and the overload collapse plate 93 are in the same plane. The steel beam connection plate 91 is vertically fixed to the side of the web plate 73. The steel beam connecting plate 91 is fixedly connected to the side of the web 73, and the upper end of the steel beam connecting plate 91 is fixedly connected to the lower surface of the upper extension plate 71, and the lower end of the steel beam connecting plate 91 is fixedly connected to the upper surface of the wing plate 92. The overload collapse plate 93 is vertically fixed to the side of the web 73, and the upper end of the overload collapse plate 93 is fixedly connected to the lower surface of the wing plate 92, and the lower end of the overload collapse plate 93 is fixedly connected to the upper surface of the lower extension plate 72.

[0046] Reference Figure 5In actual use, the wing plate 92 and the steel beam are connected through the second steel beam connecting hole 911. The wing plate 92 and the overload collapse plate 93 can play a good reinforcing role on the wing plate 92, thereby enhancing the bearing strength of the wing plate 92. At the same time, if an overload occurs, the overload collapse plate 93 will be the first to collapse and deform due to the more concentrated stress. At the same time, the connection between the steel beam and the wing plate 92 is prevented from being directly disconnected due to excessive deformation, thereby reducing safety risks.

[0047] Reference Figure 1 Specifically, the provision of the annular rib plate 8 facilitates the hoisting of the super-high load-bearing steel column structure of the subway station. The connection frame 7 cooperates with the annular rib plate 8 to maximize the structural strength and deformation resistance of the connection between the connection frame 7, the annular rib plate 8 and the circular column body 1, and enhance the load-bearing performance and bending resistance of the connection frame 7. At the same time, it can effectively improve the connection strength and connection stability between the connecting piece and the circular column body 1, thereby improving the overall load-bearing performance of the present application and meeting the super-high load-bearing requirements of the subway hub site.

[0048] Reference Figure 1 The number of the annular rib plates 8 is three, and the three annular rib plates 8 are alternately arranged up and down. The upper extension plate 71 is fixedly connected to the annular rib plate 8 located at the top, and the lower extension plate 72 is fixedly connected to the annular rib plate 8 located in the middle or the bottom. Specifically, the number of the connecting frames 7 is four, among which the lower extension plates 72 of two connecting frames 7 are fixedly connected to the annular rib plates 8 located in the middle, and the lower extension plates 72 of the remaining two connecting frames 7 are fixedly connected to the annular rib plates 8 located at the bottom.

[0049] In actual application, the connecting frame 7 is connected to the steel beam on the ground floor of the subway hub station. Most of the stress borne by the connecting frame 7 will be concentrated toward the bottom of the connecting end of the connecting frame 7. There are four connecting frames 7, of which the lower extension plates 72 of two connecting frames 7 are fixedly connected to the annular rib plate 8 located in the middle, and the lower extension plates 72 of the remaining two connecting frames 7 are fixedly connected to the annular rib plate 8 located at the bottom. The setting can avoid that too much bearing force of the connecting frame 7 is concentrated on one annular rib plate 8 and damage the connection structure of the connecting frame 7 and the annular rib plate 8, can maximize the structural strength and deformation resistance of the connection between the connecting frame 7, the annular rib plate 8 and the circular column body 1, enhance the load-bearing performance and bending resistance of the connecting frame 7, and at the same time can effectively improve the connection strength and connection stability between the connecting piece and the circular column body 1, thereby improving the overall load-bearing performance of the present application and meeting the ultra-high load-bearing requirements of the subway hub station.
