Description

Technical Field

[0001] This utility model relates to the field of deep-buried railway station technology, specifically to a column-free station smoke exhaust and lighting structure that takes into account both fire protection conditions. Background Technology

[0002] With the increasing density and expansion of the rail transit network, the underground stations are greatly affected by factors such as municipal pipelines and transfer lines. Under certain conditions, the station locations are often deep underground stations with three or even four underground levels.

[0003] If the station is located within a roadside plot, this burial depth creates conditions for innovative designs in the station's public area roof space, such as column-free design, vaulted ceilings, skylights, and sunken plazas. When the station is a two-level underground island platform station, the public area of ​​the underground concourse level adopts a column-free structural system, and continuous open skylights are opened in the longitudinal direction of the central span to introduce natural lighting into the underground space of the station and reduce the station's operating energy consumption.

[0004] However, a corresponding drawback of this approach is that the opening of the roof space leads to the loss of wartime functions of the rail transit station. Since underground rail transit stations serve as civil defense evacuation routes and temporary shelters for personnel and materials during wartime, the arrangement of open skylights connects the underground and ground spaces of the station, making the station no longer capable of serving as a fortified site. Therefore, this type of station is often considered as a station that does not serve as a fortified site. Summary of the Invention

[0005] Based on the shortcomings of the existing technology, this patent addresses the issue of stations without columns and with skylights at the top. It utilizes a novel sliding horizontal sealing plate to seal the skylight openings, thereby enhancing the visual landscape of the original column-free, large space within the station while ensuring that the station meets the requirements for fire protection.

[0006] The objective of this utility model is achieved through the following technical solution:

[0007] A column-free station smoke exhaust and lighting structure that takes into account both fire protection conditions and is used in deeply buried stations is characterized by: an open skylight extending upward to the ground on the arched structure of the deeply buried station, through which the public area of ​​the deeply buried station hall is made air-connected with the outside; a horizontal sealing plate is installed in the vertical space of the interlayer on the arched structure. The horizontal sealing plate is a push-pull sealing plate, which is stored at both ends of the equipment interlayer in the upper part of the arched structure and can be pushed out to seal the open skylight.

[0008] The horizontal sealing plate is an electrically controlled push-pull type, which provides the same sealing effect and conversion workload as the original vertical sealing plate. It increases the storage space for the horizontal sealing plate without compromising the open and transparent effect of the station's public area, which is deeply buried without columns and equipped with open skylights, while also providing a dedicated passage for daily access and maintenance from within the station.

[0009] The horizontal sealing plate is installed in the equipment mezzanine within the dome structure.

[0010] The horizontal sealing plate is normally stored in the arched interlayer for concealment, and the open skylight allows for effective communication with the outside. The air-raid shelter sealing device is activated by an electric switch and moves from both ends toward the center of the public area to horizontally seal the skylight, thus achieving the function of air-raid shelter.

[0011] Maintenance channels are provided on both sides of the horizontal sealing plate placement position located in the equipment interlayer.

[0012] Along the extension direction of the buried station, a plurality of open skylights are provided on the arch structure, and each open skylight is provided with a corresponding horizontal sealing plate.

[0013] The open skylights are arranged symmetrically around the center of the public area of ​​the station hall of the buried station.

[0014] The open skylight has maintenance access around the opening in the arch.

[0015] To enhance the effect of the station's public space, the station has further optimized its ventilation ducts by utilizing the spatial characteristics of open skylights and column-free arched structures. Building upon the existing column-free public area, the station has created a fully open underground space with "few or even no pipelines."

[0016] The open skylights allow for direct exhaust of smoke to the outside during a fire, thus eliminating the need for centralized smoke exhaust ducts at the top of the public area and utilizing the open skylights in the roof as dedicated ventilation shafts for external smoke exhaust.

[0017] Advantages of this utility model:

[0018] 1) The station created a column-free space effect in the public area of ​​the station hall, ensuring continuous, unobstructed, and open sightlines in the underground passenger activity area, forming a decorative effect of a large underground space.

[0019] 2) Open skylights are installed on the roof of the station, which creates air circulation between the indoor and outdoor areas and introduces natural light into the dull underground space. In the event of a fire, the station has the ability to directly exhaust smoke to the outside. The use of open skylights on the roof as dedicated ventilation shafts for external smoke exhaust reduces operating energy consumption and puts into practice the concept of a green station.

[0020] 3) New sliding horizontal sealing plates were used to seal the four open skylights in the arch, ensuring that the station has the conditions for fire protection while not affecting the open and unobstructed visual effect of the public area under normal working conditions.

[0021] 4) Taking advantage of the station's burial depth and clearance, an equipment mezzanine is set up above the equipment areas at both ends of the station hall level to serve as storage space for the push-pull horizontal sealing plates under normal working conditions, and maintenance paths are set up from the station to the upper mezzanine and the open section of the skylight.

[0027] The features and other related features of this utility model will be further described in detail below with reference to the accompanying drawings and embodiments, so as to facilitate the understanding of those skilled in the art:

[0028] like Figure 1-5 As shown in the figure, numbers 1-7 represent: 1. Deeply buried station, 2. Open skylight, 3. Sealing plate storage room, 4. Maintenance passage, 5. Horizontal sealing plate, 6. Station hall public area, 7. Arch structure.

[0029] Example: Figures 1 to 5 As shown, in this embodiment, the column-free station smoke exhaust and lighting structure that takes into account the fortification conditions is used for the deep-buried station 1, and the station hall public area 6 adopts an open column-free design.

[0030] Specifically, in this embodiment, the buried station 1 has an arched structure 7, and an open skylight 2 is provided above the arched structure 7. The open skylight 2 extends out of the ground and is connected to the public area 6 of the station hall inside the buried station 1 through the open skylight 2 at the top, so as to carry out natural ventilation and natural smoke exhaust, reduce the operating time of mechanical ventilation facilities to achieve the effect of energy-saving operation, and at the same time reduce mechanical smoke exhaust facilities to ensure that the underground station has both fire protection conditions.

[0031] In this embodiment, the open skylights are symmetrically arranged around the center of the station hall's public area to ensure full utilization of natural lighting to meet the lighting needs of the public area and reduce the lighting load. A shielded roof structure can be used at the opening of the open skylights to prevent rainwater from entering the buried station 1 through the open skylights, for example, during outdoor rain.

[0032] To ensure that the rail transit station meets the requirements of air defense functions, two equipment mezzanines are set up by taking advantage of the space of the equipment area on both sides of the arch and the height of the arch. Under normal circumstances, the horizontal sealing plate 5 is concealed in the sealing plate storage room 3, and the window of the open skylight 2 can effectively communicate with the outside. The horizontal sealing plate 5 is moved from both ends to the center of the platform public area 6 by an electric switch to horizontally seal the open skylight 2, so as to achieve the function of air defense shelter.

[0033] like Figure 1 and Figure 2 As shown, to facilitate the inspection and maintenance needs of operators, maintenance passages 4 are set up around the sealed plate storage room 3 and the open skylight 2 for management personnel to pass through.

[0034] Although the above embodiments have described the concept and embodiments of the present invention in detail with reference to the accompanying drawings, those skilled in the art will recognize that various improvements and modifications can still be made to the present invention without departing from the scope of the claims, and therefore will not be elaborated here.
