[0018] The present invention will now be described in detail with reference to the accompanying drawings and embodiments: like Figures 1 to 8 As shown, a modular prefabricated steel cage structure for the main structure of a subway station includes a top plate module 1 at the top, vertical and parallel side wall modules 4 connected to the lower two sides of the top plate module 1, a horizontal middle plate module 2 between the two side wall modules 4, and the lower end of the middle plate module 2 connected to the bottom plate module 3. The modular top plate module 1, middle plate module 2, bottom plate module 3, and side wall modules 4 are connected as a whole.

[0019] The top plate module 1 includes a top plate corner module 5 located at the top corner and a top plate middle module 7 located in the horizontal middle. The top plate middle module 7 is connected to the horizontal connecting section of the top plate corner module 5 on both sides through a top plate connecting module 6.

[0020] The base plate module 3 includes a base plate corner module 12 located at the bottom corner and a base plate middle module 14 located in the horizontal middle. The two sides of the base plate middle module 14 are connected to the horizontal connecting section of the base plate corner module 12 through the base plate connecting module 13.

[0021] The side wall module 4 includes an upper side wall module 15 located at the top. The upper end of the upper side wall module 15 is connected to the vertical section of the top plate corner module 5. The lower end of the upper side wall module 15 is connected to the middle side wall module 16. The lower end of the middle side wall module 16 is connected to the lower side wall module 17. The lower side wall module 17 is connected to the vertical section of the bottom plate corner module 12.

[0022] The middle module 16 of the side wall is connected to the middle plate module 2.

[0023] The middle plate module 2 includes a middle plate module 11 located in the middle, which is connected to the side wall middle module 16 through a horizontal block group of the middle plate.

[0024] The middle plate horizontal segment group includes a middle plate connecting module 10, which includes a horizontal first connecting segment, a second connecting segment, and a downwardly inclined third connecting segment.

[0025] The first connecting segment is connected to the middle module 11 of the middle plate, and the first connecting segment and the middle module 11 of the middle plate are coplanar.

[0026] The second connecting segment is connected to the upper corner module 8 of the middle plate, and the upper corner module 8 of the middle plate is connected to the side wall of the middle module 16 of the side wall.

[0027] The third connecting section is connected to the lower corner module 9 of the middle plate, and the lower corner module 9 of the middle plate is inclinedly connected to the side wall of the middle module 16 of the side wall.

[0028] Specifically, the upper corner module 8, the middle plate connecting module 10, and the lower corner module 9 of the middle plate form a triangular connecting structure.

[0029] Specifically, such as Figure 1 As shown, in the overall structure, the top plate module 1, the middle plate module 2, the bottom plate module 3, and the side wall module 4 are all connected by steel cage module units.

[0030] Specifically, such as Figure 2 As shown, the segmented structure is a further subdivision of the overall structure, including the top plate corner module 5, the top plate connection module 6, the top plate middle module 7, the middle plate upper corner module 8, the middle plate lower corner module 9, the middle plate connection module 10, the middle plate middle module 11, the bottom plate corner module 12, the bottom plate connection module 13, the bottom plate middle module 14, the upper side wall module 15, the middle side wall module 16, and the lower side wall module 17. The above segments are also connected by steel cage module units.

[0031] Specifically, the longitudinal length of the steel cage module unit is approximately 3m.

[0032] More specifically, the longitudinally adjacent steel cage modules are assembled using a staggered and mutually anchored distribution bar configuration.

[0033] More specifically, the connection surfaces of horizontally adjacent steel cage module units are set at the point where the stress is less in the one-fifth span of the slab, or at the point where the stress is less in the one-third span of the wall or in the point where the structural stress is less.

[0034] Specifically, each of the steel cage module units is made of transverse reinforcing bars 18, longitudinal distribution bars 19, and structural stirrups 20.

[0035] Specifically, such as Figures 3 to 8 As shown, the transverse reinforcing bars 18 extend beyond the connection surface of the reinforcing cage module unit at both ends. The transverse reinforcing bars 18 of adjacent modules can be connected by lap splicing, mechanical connection or welding, and meet the joint percentage requirements specified in the standard.

[0036] More specifically, when the transverse reinforcing bars 18 are mechanically connected, straight threaded steel bar joints, grouting sleeves or extrusion sleeves are used.

[0037] More specifically, when the transverse reinforcing bars 18 adopt a combination of prefabricated reinforcing cages and on-site tied reinforcing bars, the mechanical connection adopts a combination of double spiral sleeves and positive and negative threaded sleeves.

[0038] Specifically, the longitudinal distribution reinforcement 19 is a closed rectangular structure, and the longitudinal distribution reinforcement of adjacent steel cage module units adopts a staggered mutual anchoring form to meet the anchorage length.

[0039] Specifically, the intersection of the transverse reinforcing bars 18 and the longitudinal distribution bars 19 is secured with fasteners or wires to improve the integrity of the reinforcing mesh, ensure the continuity of force transmission, and the closed rectangular structure has good stability and can support the upper main bars. At the same time, the longitudinal distribution bars 19 and the main bars together form a reinforcing cage, which can effectively prevent the reinforcing cage from deforming during transportation and hoisting.

[0040] Specifically, the stirrups 20 of the steel cage module unit adopt U-shaped open stirrups or diagonal tie bars to connect the transverse reinforcing bars 18 on the soil-facing and soil-repellent sides of the steel cage module. This ensures the shear strength of the structural slab and side walls while also taking into account construction convenience.

[0041] Specifically, the height of the side wall module 4 must match the position of the steel support in the subway station's enclosure structure. This ensures the adaptability of the prefabricated steel cage's modular form to the construction procedures of the subway station's main structure.

[0042] Specifically, the top slab corner module 5 is equipped with two 300×300 pouring and vibration holes. The reinforcing bars are cut off, and after pouring and vibration are completed, short lapped reinforcing bars are tied to fill the gaps. This ensures that the concrete pouring is dense.

[0043] After determining the modular form of the prefabricated steel cage for the main structure of the subway station, the construction of the prefabricated steel cage is completed through the following steps: The first step is to prefabricate assembled steel cage module units; The second step is to install and fix the prefabricated steel cage module units of the same cross section at the corresponding positions in the foundation pit. The transverse reinforcing bars 18 can be connected into a whole by means of tying, mechanical connection or welding. The third step is to assemble the prefabricated steel cage module units of adjacent sections into a whole, and to complete the staggered and mutually anchored assembly with the longitudinal distribution bars 19 of the pre-constructed whole steel cage along the longitudinal direction. The fourth step is to construct formwork and pour concrete to form the main structure of the subway station.

[0044] The above description details one embodiment of the present utility model, but it is merely a preferred embodiment and should not be construed as limiting the scope of the present utility model. All equivalent variations and improvements made within the scope of the present utility model application should still fall within the patent coverage of the present utility model.
