Description

Technical Field

[0001] This utility model belongs to the field of grandstand technology and relates to a grandstand step structure. Background Technology

[0002] Grandstands are platforms built next to or around a venue for spectators to watch games or performances. Indoor or outdoor venues such as stadiums, gymnasiums, and playgrounds need to build grandstands. In the current technology, handrails are generally not installed on both sides of the steps of the grandstand to prevent the handrails from affecting the spectators' view. However, grandstands have a large drop, and not installing handrails poses a safety hazard.

[0003] For example, a Chinese patent discloses a grandstand structure for an indoor stadium [application number: 201720412164.4], which includes grandstand steps. The grandstand steps include vertical walls and horizontal walls. The vertical walls of the grandstand steps are provided with retractable flip-up seats. The feature is that the horizontal walls of the grandstand steps near the flip-up seats are provided with evacuation channels for human passage. The evacuation channels are covered with evacuation covers. Escape pipes are provided below the evacuation channels. Buffer nets are provided at the exit of the escape pipes. Utility Model Content

[0004] The purpose of this utility model is to address the above-mentioned problems by providing a grandstand step structure.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A grandstand staircase structure includes a grandstand main body with several stepped grandstand planes. The grandstand main body also has a stepped pedestrian walkway, which consists of the grandstand planes and auxiliary steps set on the grandstand planes. The auxiliary steps are set inside the grandstand planes where the stepped pedestrian walkway is located. The stepped pedestrian walkway is also symmetrically equipped with liftable handrail structures on both sides.

[0007] In the aforementioned grandstand step structure, the lifting handrail structure includes several sets of lifting handrail components arranged sequentially from top to bottom along the stepped pedestrian walkway. A set of lifting handrail components is provided on both the grandstand plane and the auxiliary steps within the stepped pedestrian walkway.

[0008] In the aforementioned grandstand step structure, the lifting handrail assembly includes an inclined handrail and a lifting component connected to the handrail, and the handrails in several sets of lifting handrail assemblies are connected in a straight line.

[0009] In the above-mentioned grandstand step structure, the lifting assembly includes a lifting sleeve embedded in the grandstand body. The lifting sleeve is provided with a pneumatic chamber. The pneumatic chamber is provided with a lifting rod whose top end is fixed to the handrail. The lifting rod is fixed with a lifting piston that abuts against the inner wall of the pneumatic chamber. The upper and lower sides of the lifting sleeve are respectively provided with air inlet and outlet holes connected to the pneumatic chambers on the upper and lower sides of the lifting piston.

[0010] In one of the grandstand step structures described above, a limiting sleeve is also embedded in the grandstand body, and a limiting rod connected to the top of the limiting sleeve and the handrail is slidably connected inside the limiting sleeve.

[0011] In one of the grandstand step structures described above, the auxiliary steps and the grandstand plane are integrally cast.

[0012] In the aforementioned grandstand step structure, the auxiliary steps and the grandstand plane are provided with inwardly recessed storage grooves, and the handrails can be lowered into the storage grooves.

[0013] In one of the grandstand step structures described above, the width and height of the auxiliary steps are half the width and half the height of the grandstand plane, respectively.

[0014] Compared with existing technologies, the advantages of this utility model are:

[0015] 1. The stepped pedestrian walkway is equipped with lifting handrails on both sides, which can be raised when the audience enters or leaves to provide safety protection for the audience walking in the stepped pedestrian walkway. When watching the performance, the lifting handrails can be lowered to prevent obstructing the audience's view. The grandstand plane that makes up the stepped pedestrian walkway is connected to the grandstand plane on the main grandstand. When the audience enters, the lifting handrails located at the grandstand plane can be lowered independently, allowing the audience to enter the grandstand plane outside the stepped pedestrian walkway.

[0016] 2. Installing lifting handrail components on the grandstand plane and auxiliary steps can facilitate the movement of spectators between the grandstand plane and the stepped pedestrian walkway, while the lifting handrail components on the auxiliary steps can always be raised to provide protection for spectators.

[0017] Other advantages, objectives and features of this invention will be partly apparent from the following description, and partly understood by those skilled in the art through study and practice of this invention. Attached Figure Description

Detailed Implementation

[0025] like Figures 1-6 As shown, a grandstand step structure includes a grandstand body 1, on which several stepped grandstand planes 2 are provided. The grandstand body 1 is also provided with a stepped pedestrian walkway 3, which consists of the grandstand planes 2 and auxiliary steps 4 provided on the grandstand planes 2. The auxiliary steps 4 are located inside the grandstand planes 2 where the stepped pedestrian walkway 3 is located. The stepped pedestrian walkway 3 is also symmetrically provided with lifting handrail structures 5 on both sides.

[0026] In this utility model, the stepped pedestrian walkway is equipped with lifting handrails on both sides, which can be raised when the audience enters or leaves to provide safety protection for the audience walking in the stepped pedestrian walkway. When watching the performance, the lifting handrails can be lowered to prevent obstructing the audience's view. The grandstand plane 2 that makes up the stepped pedestrian walkway 3 is connected to the grandstand plane on the main grandstand. When the audience enters, the lifting handrails located at the grandstand plane 2 can be lowered independently, allowing the audience to enter the grandstand plane outside the stepped pedestrian walkway 3.

[0027] Specifically, the lifting handrail structure 5 includes several sets of lifting handrail components 6 arranged sequentially from top to bottom along the stepped pedestrian walkway 3. Each set of lifting handrail components 6 is installed on both the grandstand plane 2 and the auxiliary steps 4 within the stepped pedestrian walkway 3. The installation of lifting handrail components on the grandstand plane 2 and the auxiliary steps 4 facilitates the movement of spectators between the grandstand planes inside and outside the stepped pedestrian walkway, while the lifting handrail components on the auxiliary steps can always remain raised to provide safety for the spectators.

[0028] Specifically, the lifting handrail assembly 6 includes an inclined handrail 7 and a lifting component connected to the handrail 7. Several sets of handrails 7 within the lifting handrail assemblies 6 are connected in a straight line. The lifting component can drive the handrail to rise and fall vertically.

[0029] Specifically, the lifting assembly includes a lifting sleeve 8 embedded within the main body 1 of the grandstand. The lifting sleeve 8 contains a pneumatic chamber 9, and within the pneumatic chamber 9 is a lifting rod 10, the top of which is fixedly connected to the handrail 7. A lifting piston 11, abutting against the inner wall of the pneumatic chamber 9, is fixedly mounted on the lifting rod 10. The upper and lower sides of the lifting sleeve 8 are respectively provided with air inlet and outlet holes 12 connected to the pneumatic chambers 9 on the upper and lower sides of the lifting piston 11. Inflating the pneumatic chamber through the air inlet and outlet holes on the lower side of the lifting sleeve drives the lifting piston upward, thereby raising the lifting rod and the handrail connected to it. Inflating the pneumatic chamber through the air inlet and outlet holes on the lower side of the lifting sleeve drives the lifting piston downward, thereby lowering the lifting rod and the handrail connected to it.

[0030] Preferably, a limiting sleeve 13 is also embedded inside the main body 1 of the grandstand, and a limiting rod 14, whose top is connected to the handrail 7, is slidably connected inside the limiting sleeve 13. The limiting rod, in conjunction with the limiting sleeve, can limit the handrail when it rises or falls, and can also improve the stability of the handrail.

[0031] Specifically, the auxiliary steps 4 and the grandstand plane 2 are integrally cast. Recessed grooves 15 are provided on both the auxiliary steps 4 and the grandstand plane 2, allowing the handrail 7 to descend into these grooves. The recessed grooves allow the handrail to sink completely into the grandstand, preventing spectators from tripping over it.

[0032] Specifically, the width and height of the auxiliary step 4 are half the width and height of the grandstand plane 2, respectively.

[0033] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.

[0034] Although this article frequently uses terms such as grandstand body 1, grandstand plane 2, stepped pedestrian walkway 3, auxiliary steps 4, lifting handrail structure 5, lifting handrail assembly 6, handrail 7, lifting sleeve 8, air pressure chamber 9, lifting rod 10, lifting piston 11, air inlet and outlet 12, limiting sleeve 13, limiting rod 14, and storage groove 15, these terms are used merely to more conveniently describe and explain the essence of this utility model; interpreting them as any kind of additional limitation would contradict the spirit of this utility model.
