[0031] Embodiment:

[0032] Figure 1 is the first cross-sectional view of an atrium subway station with earthquake resistance performance provided by an embodiment of the present utility model, Figure 2 is the second cross-sectional view of an atrium subway station with earthquake resistance performance provided by an embodiment of the present utility model, combined with Figure 1 and Figure 2 as shown, the atrium subway station includes a top plate 1, a bottom plate 2, a middle plate 3 and a plurality of side walls 4.

[0033] The top plate 1, the bottom plate 2 and the plurality of side walls 4 are all arched structures, and are all concave and enclose to form a station space. The outer edge of the middle plate 3 is fixedly connected to the plurality of side walls 4 to divide the station space into a concourse space A and a platform space B.

[0034] Figure 3 is the structural schematic diagram of the middle plate provided by an embodiment of the present utility model. As Figure 3 shown, there are at least two atriums 31 arranged at intervals on the middle plate 3. Each atrium 31 communicates the concourse space A and the platform space B. A platform plate 21 parallel to the middle plate 3 is provided on the bottom plate 2.

[0035] For an atrium subway station with earthquake resistance performance provided by an embodiment of the present utility model, since there are at least two atriums 31 arranged at intervals on the middle plate 3, by designing the atriums 31, the visual effect of the subway station space is greatly improved, thereby improving the comfort of passengers passing through.

[0036] Furthermore, since the top plate 1, the bottom plate 2, and the multiple side walls 4 are all arched structures, and they are all concave and enclose to form the station space, the arched structure has high strength. Thus, the structural strength of the atrium subway station is improved through the arched design, and it can effectively make up for the influence of the opening (i.e., the atrium) on the middle plate 3, which weakens the support of the middle plate 3 to the side walls 4. Furthermore, the seismic performance requirements of the station are met, and a large number of columns do not need to be set, thereby further improving the visual effect of the subway station space.

[0037] That is to say, an atrium subway station with seismic performance provided by the embodiment of the present invention not only meets the seismic performance requirements of the station, but also improves the visual effect of the subway station space.

[0038] In one implementation manner of the present invention, a connecting ladder 32 connecting the bottom plate 2 and the middle plate 3 is provided on one side of each atrium 31. The atrium 31 provides space for the installation of the connecting ladder 32, increases the utilization rate of the internal space of the station, and facilitates passengers to enter and exit the concourse space and the platform space.

[0039] Exemplarily, the connecting ladder 32 can be a staircase or an escalator. A guardrail is set at the edge of the atrium 31 to ensure the safety of passengers, and a dust-proof strip is provided inside the guardrail.

[0040] It should be noted that other structures such as ticket gates are also correspondingly provided on the middle plate 3, and the present invention does not limit this.

[0041] In addition, in order to increase the connection strength between the side wall 4 and the top plate 1 or the bottom plate 2, an arch springing structure 9 is provided at the connection, thereby increasing the connection strength at the connection.

[0042] In this embodiment, each atrium 31 is a square structure, and the length of each atrium 31 is 60 - 80 m, and the width of each atrium 31 is 7 - 10 m. The atrium 31 has a large size span, thus providing passengers with an open and bright view.

[0043] In addition, the interval between two atriums 31 is 15 - 20 m, preferably 17 m.

[0044] Exemplarily, the thicknesses of the top plate 1 and the bottom plate 2 are both 1.2 m, the thicknesses of the middle plate 3 and the side wall 4 are both 0.5 m, and the distance between two side walls 4 is 21.5 m. The platform slab 21 is an island platform structure with a width of 12 m.

[0045] Continue to refer to Figure 1 and Figure 2 , there are two support walls 5 arranged in parallel and spaced apart in the platform space B, and the bottom of each support wall 5 is fixedly connected to the bottom plate 2, and the top of each support wall 5 is vertically connected to the platform slab 21.

[0046] In the above-described embodiment, the support wall 5 supports and elevates the platform slab 21, facilitating passengers to get on and off between the train and the platform slab 21.

[0047] Exemplarily, the support wall 5 is of a concrete structure.

[0048] Furthermore, there is a plain concrete backfill layer 6 in the platform space B. The plain concrete backfill layer 6 is laid on the floor slab 2. The bottom of each support wall 5 is embedded in the plain concrete backfill layer 6, and the platform slab 21 is arranged at an interval from the plain concrete backfill layer 6. The plain concrete backfill layer 6 supports the train track and can also assist in supporting the support wall 5.

[0049] In one implementation manner of the present utility model, the bottom surface of the middle slab 3 has two oppositely arranged haunches 7, and one side of each haunch 7 is fixed to the corresponding side wall 4.

[0050] It is easy to understand that the haunches 7 can increase the connection strength between the side wall 4 and the middle slab 3, further compensating for the influence of the opening in the middle slab 3 on the support of the side wall 4 being weakened.

[0051] Exemplarily, the haunches 7 extend along the length direction of the middle slab 3.

[0052] In addition, each haunch 7 is provided with an air duct 71, and the air duct 71 is communicated with the outside atmosphere, thereby realizing the gas exchange between the inside of the subway and the outside.

[0053] In this embodiment, a suspended wall 72 is arranged on the side of each haunch 7 facing the platform slab 21. The suspended wall 72 is arranged at an interval from the platform slab 21 to form an installation space for installing platform doors.

[0054] In the above-described embodiment, the suspended wall 72 can provide a support point, thereby cooperating with the platform slab 21 to clamp and support the platform doors.

[0055] Exemplarily, the suspended wall 72 is directly opposite the edge of the platform slab 21.

[0056] In addition, the atrium subway station further includes a fire passage 8. The fire passage 8 is used to connect the ground 100 and the middle slab 3, so as to evacuate passengers in case of an emergency.

[0057] Those skilled in the art can easily understand that the above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent replacements, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
