Description

Technical Field

[0001] This utility model relates to the field of subway station construction technology, and in particular to a kind of enclosure for renovation inside a subway station. Background Technology

[0002] As vital transportation hubs in cities, subway stations require continuous renovation and upgrades due to urban development and increasing passenger flow, such as platform expansion and facility updates. During renovations, construction barriers must be erected to ensure safety. These barriers must guarantee both smooth construction progress and the safety of subway operations, while also providing fireproofing, waterproofing, smoke prevention, and noise reduction to minimize disruption to passenger flow and operations. Furthermore, as a gateway to the city, the design of subway station barriers must blend seamlessly with the urban culture and subway environment, utilizing environmentally friendly materials to reduce environmental impact while also ensuring aesthetic appeal and enhancing the passenger experience.

[0003] Existing construction site fencing is typically either fixed or modular. Fixed fencing is mostly made of brick or concrete, which is structurally stable but difficult to dismantle, cannot be reused, has a long construction period, and is costly. Modular fencing uses metal sheets for splicing, which is easy to assemble but has limited functionality and is inadequate in terms of fire resistance, waterproofing, smoke prevention, and noise reduction. It is also difficult to balance environmental protection and aesthetics, making it hard to meet the complex needs of subway station renovation. Summary of the Invention

[0004] The purpose of this utility model is to overcome the above-mentioned defects of the existing technology and propose a fence for the renovation of subway stations. It adopts a modular structure, which is easy to assemble and disassemble, can be reused, can be flexibly adjusted according to the site space, has strong adaptability, and improves construction efficiency.

[0011] The bases of two adjacent plug-in uprights are connected by a ground rubber strip baffle. The ground rubber strip baffle is located directly below the first barrier plate. The ground rubber strip is compressed under the pressure of the first barrier plate, thus playing a sealing role. The base has a wedge-shaped tenon groove on its side and a wedge-shaped protrusion at the end of the floor strip. The wedge-shaped protrusion is fixed in the wedge-shaped tenon groove by interference fit.

[0012] Supporting poles are provided on the side walls along the width direction of the fence. The supporting poles are located at both ends of the fence facing the outer wall. The bottom of the supporting poles is fixed to the ground by the base, and the top of the supporting poles is fixedly connected to the curved poles. Several first barrier plates are provided between the support pole and the corresponding socket-type pole, and the first barrier plates are stacked sequentially along the vertical direction; A ground-mounted rubber strip baffle is connected between the base of the support pole and the base of the socket-type pole, and the ground-mounted rubber strip baffle is located directly below the first barrier plate.

[0013] The fence is provided with a first support pole and a second support pole along the width direction of the side wall.

[0019] Specific details are set forth in the following description to provide a full understanding of the present invention. However, the present invention can be implemented in many ways other than those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0020] like Figure 1 As shown, the subway station renovation enclosure of this utility model includes several vertically arranged plug-in uprights 4, curved uprights 5 connected to the top of the plug-in grooved uprights, a first barrier plate 3 located between two adjacent plug-in uprights, and a second barrier plate 6 located between two adjacent curved grooved uprights. Several first barrier plates 3 form the outer wall of the enclosure, and several second barrier plates 4 form the top wall of the enclosure. The outer wall and the top wall together form the enclosure of this utility model.

[0021] The outer sidewall includes a sidewall along the length direction and a sidewall along the width direction. The sidewall along the length direction includes several plug-in uprights 4, a first barrier plate 3, and a ground rubber strip baffle 1. The plug-in uprights 4 are spaced apart along the length direction of the enclosure. The first barrier plate is clamped between two adjacent plug-in uprights 4. The ground rubber strip baffle 1 is located below the first barrier plate 3.

[0022] The side wall along the width direction includes a support pole 17 arranged in the vertical direction. A first barrier plate 3 is engaged between the support pole 17 and the socket-type pole 4 on its outer side. A ground rubber strip baffle 1 is provided below the first barrier plate 3.

[0023] The bottom of the socket-type upright 4 is fixed to the ground via the base 2. For example... Figure 2 As shown, the main body of the socket-type upright 4 is made of I-beams, which are arranged vertically. A first fixing plate 11 is connected to the bottom of the socket-type upright 4, and the upright 4 is fixedly connected to the first fixing plate 11 by insertion. In this embodiment, a first slot 10 is provided on the top surface of the first fixing plate 11. The first slot 10 is I-shaped, and the bottom of the main body of the socket-type upright 4 is inserted and fixed within the first slot 10.

[0024] The first fixing plate 11 is fixedly connected to the base 2 by several bolts. For example... Figure 3 As shown, the base 2 is provided with a first bolt hole 8, and the corresponding first fixing plate 11 is provided with a second bolt hole 9. The bolt passes through the first bolt hole 8 and the second bolt hole 9 in sequence, thereby realizing the fixed connection between the first fixing plate 11 and the base 2.

[0025] like Figure 3 As shown, the rubber strip baffle 1 and the base 2 are fixedly connected by mortise and tenon joints. In this embodiment, the side of the base 2 is provided with a wedge-shaped tenon groove, and a corresponding wedge-shaped protrusion is provided at the end of the rubber strip baffle 1. The wedge-shaped protrusion is set in the wedge-shaped tenon groove by an interference fit, thereby realizing the fixed connection between the base 2 and the rubber strip 1. At the same time, the base 2 and the socket-type column can be fixedly connected by bolts or by anchor bolts or other methods. The base 2 is fixed to the ground by expansion bolts.

[0026] Several first barrier plates 3 are fixedly installed between two adjacent plug-in uprights 4. These first barrier plates 3 are arranged and stacked sequentially from bottom to top, with both ends of each first barrier plate 3 engaging with the inner grooves of the adjacent plug-in uprights, thus connecting the first barrier plates 3 to the plug-in uprights 4. A ground-level rubber strip baffle 1 is located directly below the first barrier plates 3. The ground-level rubber strip baffle 1 has a certain degree of elasticity. After the first barrier plates 3 are installed, they compress the ground-level rubber strip baffle 1 below them, causing a certain amount of compression. The compressed ground-level rubber strip baffle 1 provides a good seal between itself and the ground and the first barrier plates 3, meaning it acts as a seal between the ground and the first barrier plates 3, thus giving the fence a certain degree of waterproofing.

[0027] like Figure 6 As shown, the first barrier plate 3 is a quadrilateral shell shape, with a cavity inside and a core plate inside the cavity. In this embodiment, the first barrier plate 3 is made of metal, and several holes are provided on the inner surface of the first barrier plate 3 to facilitate the absorption of external noise by the core plate inside the cavity.

[0028] The built-in core board in this embodiment is made of rock wool board, which has the functions of fireproof, waterproof, sound absorption and sound insulation, as well as fatigue resistance and impact resistance.

[0029] The top of the socket-type upright 4 is fixedly connected to the curved upright 5. The curved upright 5 is bent and includes a bent section and a horizontal section. The bottom end of the bent section of the curved upright is fixedly connected to the top end of the socket-type upright 4, and one end of the horizontal section of the curved upright is fixedly connected to the external wall.

[0030] like Figure 4As shown, the body of the curved upright 5 is made of I-beams, and one end of the I-beam of the curved upright 5 is fixedly connected to the socket-type upright 4. The other end of the I-beam of the curved upright 5 is fixedly connected to the second fixing plate 14. The curved upright 5 is fixedly connected to the external wall through the second fixing plate 14.

[0031] The connection structure between the bent section of the curved upright 5 and the socket-type upright 4 is as follows: Figure 5 As shown, a connecting plate 15 is provided at the intersection of the curved upright 5 and the socket-type upright 4. The upper end of the connecting plate 15 is fixedly connected to the body of the curved upright 5 by connecting bolts 16, and the lower end of the connecting plate 15 is fixedly connected to the body of the socket-type upright 4 by connecting bolts 16. Therefore, the connecting plate 15 realizes the fixed connection between the bent section of the curved upright 5 and the top of the socket-type upright 4.

[0032] like Figure 4 As shown, a second slot 13 is provided on one side of the second fixing plate 14. The second slot is I-shaped, and the end of the bent upright 5 is fixedly inserted into the second slot 13, thereby realizing the fixed connection between the bent upright 5 and the second fixing plate 14. A third bolt hole 12 is provided on the second fixing plate 14. The second fixing plate 14 is fixedly connected to the external wall by bolts set in the third bolt hole 12, thereby fixing the fence to the external wall of the subway.

[0033] Several second barrier plates 6 are fixedly installed between two adjacent curved uprights 5. These second barrier plates are arranged sequentially, with their two sides respectively positioned within the grooves of the adjacent curved uprights, thus achieving the connection between the second barrier plates 6 and the curved uprights 5. The second barrier plates 6 are made of metal and have a cavity inside, filled with a core board. Several holes are provided on the inner surface of the second barrier plates 6 to facilitate the absorption of external noise by the core board within the cavity. In this embodiment, the built-in core board can be made of rock wool.

[0034] The bottom of the support pole 17 is fixed to the ground via the base 2, and the top of the support pole 17 is bolted to the curved pole 5. Several first barrier plates 3 are provided between the support pole 17 and the outer socket-type pole 4. The first barrier plates 3 are connected and stacked sequentially from bottom to top to form a sidewall along the width direction. A ground-level rubber strip baffle 1 is connected between the base of the support pole and the base of the socket-type pole. The ground-level rubber strip baffle 1 is located directly below the first barrier plates 3. Under the weight of the first barrier plates 3, the ground-level rubber strip baffle 1 is compressed, thus providing a sealing effect.

[0035] In this embodiment, a side door 7 is provided on one side wall along the width direction. Two vertically positioned support pillars, namely the first support pillar and the second support pillar, are located on this side wall. Both the first and second support pillars are fixedly connected to the horizontal section of the curved pillar 5. Several first barrier plates 3 are stacked sequentially from bottom to top between the first support pillar and the corresponding socket-type pillar 4. The side door 7 is formed between the first and second support pillars, allowing convenient communication between the subway station to be renovated and the outside. The bottom of the first and second support pillars are respectively provided with bases. A floor-mounted rubber strip baffle 1 connects the base of the socket-type pillar to the base of the first support pillar, and also connects the base of the first and second support pillars to the base of the second support pillar. The floor-mounted rubber strip baffle 1 serves a sealing function.

[0036] During the installation of the fence, the foundation is first constructed by mortise and tenon joints between the base strip 1 and the base 2. Once the base strip and base are assembled to the required fence length, the bottom of the insert-type uprights 4 are fixedly connected to the base 2 using bolts or anchors. After the insert-type uprights 4 are installed to the appropriate height, the top of the curved uprights 5 is fixedly connected to the insert-type uprights 4 using connecting plates 15 and connecting bolts 16. Finally, the fence is fixed to the external wall using the second fixing plate 14. This completes the assembly of the fence frame.

[0037] After the fence frame is assembled, the first barrier plate 3 is installed between two adjacent plug-in uprights 4, the first barrier plate 3 is installed between the plug-in uprights 4 and the support uprights 17, the second barrier plate 6 is fixedly installed between two adjacent curved uprights 5, and finally the side door 7 is installed between two adjacent support uprights.
