These terms are used solely for the convenience of describing this application and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application. The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. That is, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. Furthermore, unless otherwise stated, "a plurality of" means two or more.

[0020] Furthermore, the technical features involved in the different embodiments of this application described below can be combined with each other as long as they do not conflict with each other.

[0021] like Figures 1-2 As shown, the station hall structure of the underground station in this embodiment of the present invention includes frame columns 1, upturned beams 2 and roof slab 3.

[0022] The frame column 1 includes a column body 11 and column reinforcement bars 12 disposed within the column body 11. The frame column 1 is used to support the upward-turning beam 2.

[0023] The upturned beam 2 is connected to the upper end of the frame column 1. The upturned beam 2 has an upturned part 21, an inclined part 22, and a horizontal part 23. The inclined part 22 is located on both longitudinal sides of the upturned part 21, and the horizontal part 23 is located on the side of the inclined part 22 away from the upturned part 21. The top surface of the upturned part 21 is higher than the top surface of the horizontal part 23, and the bottom surface of the upturned part 21 is higher than the bottom surface of the horizontal part 23. The upturned beam 2 includes a beam body 24 and horizontal bars 25, longitudinal bars 26, and stirrups 27 provided in the beam body 24. The horizontal bars 25 are connected to the longitudinal bars 26, and the stirrups 27 are connected to the longitudinal bars 26. The upturned part 21 is provided to create an installation space at the bottom of the upturned beam 2 for installing pipelines, thus avoiding affecting the height of the suspended ceiling.

[0024] The top slab 3 is connected to both sides of the upward-turning beam 2. The top slab 3 is made of reinforced concrete to ensure the stability of the underground station hall structure.

[0025] In this embodiment, the upper end of the column reinforcement 12 is located inside the beam 24, and the longitudinal reinforcement 26 passes through the column reinforcement 12. Thus, the longitudinal reinforcement 26 and the column reinforcement 12 do not need to be mutually anchored; only a binding connection is required. This improves construction efficiency and enhances the concrete pouring conditions at the joint area between the frame column 1 and the upturned beam 2.

[0026] Based on the above structural configuration, the upturned beam 2 has an upturned part 21, an inclined part 22, and a horizontal part 23. By setting the upturned part 21, an installation space is formed at the bottom of the upturned beam 2 to install pipelines, thus avoiding affecting the height of the suspended ceiling.

[0027] like Figure 1 As shown, in some embodiments, the top surface of the top plate 3 is flush with the top surface of the horizontal portion 23. This facilitates the pouring and construction of the top plate 3 and the horizontal portion 23.

[0028] like Figure 1 As shown, in some embodiments, the bottom surface of the top plate 3 is flush with the bottom surface of the upturned part 21. This facilitates the pouring and construction of the top plate 3 and the upturned part 21.

[0029] like Figure 1 As shown, in some embodiments, the frame column 1 includes a first frame column 13 and a second frame column 14. The first frame column 13 is located below the connection between the upward-turning part 21 and the inclined part 22, and the second frame column 14 is located below the connection between the inclined part 22 and the horizontal part 23. In this way, the first frame column 13 and the second frame column 14 can effectively support the upward-turning beam 2.

[0030] In some embodiments, the distance between the two first frame columns 13 is 12-18m, and the distance between the first frame column 13 and the second frame column 14 is 8-10m. It should be noted that when the distance between the two first frame columns 13 is greater than 18m, the upturned beam 2 adopts a steel-concrete composite beam structure.

[0031] like Figure 1 As shown, in some embodiments, the top surface of the upward-turning portion 21 is 0.2-0.5m higher than the top surface of the horizontal portion 23. This helps to ensure the thickness of the upward-turning portion 21.

[0032] like Figure 1As shown, in some embodiments, the bottom of the upward-turning portion 21 has a first plane 211, inclined surfaces 212 arranged longitudinally on both sides of the first plane 211, and a second plane 213 arranged on the side of the inclined surface 212 away from the first plane 211. The first plane 211 is higher than the second plane 213. The first plane 211 is flush with the bottom surface of the top plate 3, and the second plane 213 is flush with the bottom surface of the horizontal portion 23. In this way, the bottom of the upward-turning portion 21 can provide space for installing pipelines, avoiding affecting the height of the suspended ceiling.

[0033] like Figure 1 As shown, in some specific embodiments, the angle between the inclined plane 212 and the horizontal direction is 30-45°.

[0034] like Figure 1 As shown, in some specific embodiments, the length of the second plane 213 along the longitudinal direction is 1.5-4m.

[0035] like Figure 1 As shown, in some specific embodiments, column 11 is a concrete column and beam 24 is a concrete beam. This facilitates casting and shaping.

[0036] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of the present utility model, and these improvements and substitutions should also be considered within the protection scope of the present utility model.
