Description

Technical Field

[0001] This utility model relates to the field of high-altitude platform technology, specifically to an arc-shaped rotating platform attached to a high-altitude bridge. Background Technology

[0002] There is now a kilometer-long steel truss suspension bridge in the mountainous area. This bridge not only serves as a key infrastructure connecting the two banks and solving regional transportation bottlenecks, but also, with its majestic appearance and thrilling crossing, has quickly become a popular tourist attraction, drawing countless visitors to take photos and create lasting memories. To further promote the development of "bridge-tourism integration" and enhance the depth and breadth of the visitor experience, the bridge has been specially designed with a performance platform extending outward from the main structure, providing visitors with more diverse and enriching experiences.

[0003] Traditional sightseeing platform designs primarily focus on meeting the load-bearing requirements of large numbers of tourists and ensuring safety and stability. Therefore, they are often structurally bulky and lack flexibility. When these platforms are used as performance stages, their cumbersome support structures often become visual obstacles, obscuring the performers' presence and failing to blend seamlessly with the high-altitude environment, thus failing to achieve the desired sense of suspension and visual impact. There is an urgent need for a performance platform that is attached to a high-altitude bridge and embodies a sense of suspension. Utility Model Content

[0004] The present invention aims to provide an arc-shaped rotating platform attached to a high-altitude bridge to solve the technical problem that existing sightseeing platforms cannot be used for stage performances and meet the requirements of levitation effect.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: an arc-shaped rotating platform attached to a high-altitude bridge, comprising:

[0006] A vertical extension mechanism extends downward from the bottom end of a support structure for attachment and is fixedly connected to the support structure;

[0007] A horizontal extension mechanism extends from the bottom end of the vertical extension mechanism to the outside of the load-bearing structure. The horizontal extension mechanism includes a horizontal plate and an arc-shaped plate. The horizontal plate is fixedly connected to the vertical extension mechanism. The arc-shaped plate is located on the side of the horizontal plate away from the load-bearing structure and is located at the center of that side of the horizontal plate.

[0008] A keel frame is fixedly connected to the side of the horizontal plate with an arc plate. The keel frame includes a variable curvature fan ring frame, which includes an outer arc edge, an inner arc edge, and two ring width edges. The two ring width edges are located on both sides of the outer arc edge and the inner arc edge, and are fixedly connected to form a closed frame. The inner arc edge is attached to the outer edge of the arc plate, and the curvature and arc length of the outer arc edge are both greater than those of the inner arc edge.

[0009] A tempered glass plate is fixedly installed on the keel frame, and the upper surface of the tempered glass plate is flush with the horizontal extension mechanism. The tempered glass plate is a variable curvature fan ring, which includes an outer arc edge, an inner arc edge, and two ring width edges. The inner arc edge of the tempered glass plate is in contact with the inner arc edge of the variable curvature fan ring frame. The ring width edge of the tempered glass plate is longer than the ring width edge of the variable curvature fan ring frame. The curvature of the outer arc edge is the same as the curvature of the outer arc edge, and the arc length of the outer arc edge is greater than the arc length of the outer arc edge.

[0010] The principles and advantages of this scheme are as follows: The vertical extension mechanism is responsible for firmly connecting the platform to the bridge's load-bearing structure, ensuring the stability and safety of the entire platform; the horizontal plate serves as the platform's base, providing stable support; the curved plate is located outside the horizontal plate, and its curvature design not only meets aesthetic requirements and guides the audience's line of sight, enhancing the stage's depth, but also facilitates the installation of the curved tempered glass panel; the keel frame, as the supporting structure for the tempered glass panel, enhances structural stability and visual concealment of the supporting structure through its outer and inner curved edge curvature design; the tempered glass panel, as the main body of the platform, extends beyond the keel frame on its outer edge, forming a cantilever structure, further enhancing the levitation effect.

[0011] Through the variable curvature fan-shaped design and the cantilevered structure of the tempered glass panels, the platform presents a sense of outward expansion and depth, weakening the supporting structure of the keel frame and creating the visual effect of the tempered glass panels floating in the air, perfectly blending with the surrounding high-altitude environment. The curved, spiraling platform design allows performers to perform from multiple angles at high altitudes, and the audience can also view the performance from multiple angles more comprehensively, greatly enhancing the stage effect.

[0012] As an improvement, the keel frame also includes multiple secondary support rods, which are distributed with equal arc lengths on the outer and inner arc edges. The secondary support rods divide the variable curvature fan ring frame into multiple non-uniform curved arc single frames. The tempered glass plate includes multiple glass sub-plates, and the joint between two adjacent glass sub-plates is located on the secondary support rods.

[0013] The beneficial effects of this improvement are: it makes the stress distribution of the entire keel frame more even, effectively avoiding structural damage caused by excessive stress at a single point, thereby enhancing the overall structural stability of the platform. The tempered glass panel is divided into multiple glass sub-panels, with the joints between adjacent sub-panels located on the secondary support rods. This design not only simplifies the installation process of the tempered glass panel but also ensures that each glass sub-panel receives independent support. Although the addition of the secondary support rods increases the structural complexity of the platform to some extent, through reasonable design, the secondary support rods can be cleverly hidden at the joints of the tempered glass panels, thus not significantly affecting the overall visual effect of the platform.

[0014] As an improvement, the glass sub-plate is fixedly connected to the keel frame by a mounting bracket, and a metal damper for earthquake resistance is also provided between the mounting brackets of adjacent glass sub-plates. The metal damper is located on the side of the mounting bracket near the outer arc edge of the tempered glass plate.

[0015] The beneficial effects of this improvement are as follows: The design of the mounting frame makes the connection between the glass sub-panels and the keel frame simpler and more stable. It provides a standardized interface, allowing the glass sub-panels to be quickly installed on the keel frame while ensuring a secure connection. The placement of metal dampers between the mounting frames of adjacent glass sub-panels, particularly on the side of the mounting frame near the outer arc edge of the tempered glass panel, effectively absorbs the propagation of horizontal vibrations from the platform. Due to strong winds at high altitudes and potential jumping movements by performers, vibrations are generated; the metal dampers absorb and dissipate this vibrational energy, thereby improving the platform's stability, extending the lifespan of the glass sub-panels, and reducing fatigue at the connection points caused by vibration.

[0016] As an improvement, multiple metal dampers are also provided between the vertical extension mechanism and the load-bearing structure. The metal dampers are diagonally supported, with one end fixedly connected to the load-bearing structure and the other end fixedly connected to the vertical extension mechanism.

[0017] The beneficial effects of this improvement are as follows: Installing metal dampers diagonally between the vertical extension mechanism and the load-bearing structure significantly eliminates vertical vibrations of the platform. This design is crucial for improving the overall stability of the platform, especially during strong winds or when performers are engaging in strenuous activities, ensuring the platform's safety and reliability. The metal dampers not only provide seismic resistance but also enhance the overall structural strength to a certain extent. As additional support elements, they can share some of the load, reducing the burden on other structural components and thus increasing the overall load-bearing capacity of the platform.

[0018] As an improvement, the metal damper includes an outer cylinder, an inner drive rod, and shear ring plates. The shear ring plates include an inner fixed ring, an outer fixed ring, and multiple hourglass-shaped metal plates. One end of each metal plate is fixedly connected to the inner fixed ring, and the other end is fixedly connected to the outer fixed ring. The inner fixed ring is fitted around the inner drive rod and fixedly connected. The outer side of the outer fixed ring is fixedly connected to the inner wall of the outer cylinder. The multiple shear ring plates are arranged sequentially along the length of the inner drive rod.

[0019] The beneficial effects of this improvement are: when the metal damper is subjected to external force, the metal sheet can undergo elastic deformation and absorb energy; it improves the energy dissipation efficiency of the damper and extends its service life; the axial piston-shaped design makes the installation form of the metal damper more versatile, supporting diagonal support, herringbone support, elbow support, etc.; this metal damper can adapt to vibrations of different directions and intensities, and consumes vibration energy through the elastic deformation of the metal sheet, thereby effectively reducing the vibration amplitude of the platform, transforming the traditional curved metal damper into an axial piston-shaped metal damper, enhancing energy dissipation performance and assembly performance.

[0020] As an improvement, structural adhesive is used to fill the joints between adjacent glass panels.

[0021] The beneficial effects of this improvement are as follows: filling the joints between adjacent glass sub-panels with structural adhesive effectively enhances the platform's sealing performance. This not only prevents moisture, dust, and other impurities from entering the joints and causing corrosion or contamination, but also reduces joint expansion or contraction caused by temperature changes, thereby extending the platform's service life. As a high-strength adhesive, the structural adhesive firmly bonds adjacent glass sub-panels together. Even under extreme conditions (such as strong winds or earthquakes), it ensures the connection strength at the joints, preventing glass sub-panels from detaching or being damaged due to excessive stress.

[0032] Example

[0033] The basics are as follows: Figure 1 Appendix Figure 2 Appendix Figure 3 and attached Figure 4 As shown, an arc-shaped spiral platform attached to a high-altitude bridge includes a vertical extension mechanism 2, a horizontal extension mechanism 3, a frame 4, a tempered glass panel 5, and a load-bearing structure 1 for attachment. The load-bearing structure 1 includes a building or structure. In this embodiment, the load-bearing structure 1 specifically refers to the high-altitude bridge, which serves as the attachment body of the arc-shaped spiral platform.

[0034] A vertical extension mechanism 2 extends downward from the bottom end of the supporting structure 1. The top end of the vertical extension mechanism 2 is fixedly connected to the supporting structure 1 via bolts and welding. A horizontal extension mechanism 3 is fixedly connected to the end of the vertical extension mechanism 2. The horizontal extension mechanism 3 extends outward from the bottom end of the vertical extension mechanism 2 towards the outside of the supporting structure 1. One side of the horizontal extension mechanism 3 is fixedly connected to the vertical extension mechanism 2 via bolts and welding, and the other side of the horizontal extension mechanism 3 is fixedly connected to a frame 4. A tempered glass panel 5 is fixedly installed on the frame 4, and the upper surface of the tempered glass is flush with the horizontal extension mechanism 3.

[0035] In addition, multiple metal dampers 15 are specially provided between the vertical extension mechanism 2 and the load-bearing structure 1. These dampers are diagonally supported, with one end fixed to the load-bearing structure 1 and the other end connected to the vertical extension mechanism 2, which further enhances the stability of the structure.

[0036] The horizontal extension mechanism 3 includes a horizontal plate 6 and an arc plate 7. The horizontal plate 6 is fixedly connected to the vertical extension mechanism 2. The arc plate 7 is connected to the center of the side of the horizontal plate 6 away from the load-bearing structure 1. The arc plate 7 is integrally formed with the horizontal plate 6, and the outer edge of the arc plate 7 is arc-shaped.

[0037] The frame 4 includes a variable curvature fan-shaped frame 8 and secondary support rods 9. The variable curvature fan-shaped frame 8 includes an outer arc edge 10, an inner arc edge 11, and two ring width edges 12. The two ring width edges 12 are located on both sides of the outer arc edge 10 and the inner arc edge 11, respectively, connecting one end of the outer arc edge 10 to one end of the inner arc edge 11 to form a closed frame. The inner arc edge 11 is fitted with the outer edge of the arc plate 7, and the two ring width edges 12 are located on both sides of the inner arc edge 11 and are fitted with the outer edge of the horizontal plate 6. The curvature of the outer arc edge 10 is greater than that of the inner arc edge 11, making the outer arc edge 10 appear as a spiral arc relative to the inner arc edge 11. The secondary support rods 9 are located inside the variable curvature fan-shaped frame 8, and both ends of the secondary support rods 9 are fixedly connected to the outer arc edge 10 and the inner arc edge 11, respectively. There are multiple secondary support rods 9, and the multiple secondary support rods 9 are distributed on the outer arc edge 10 and the inner arc edge 11 with equal arc lengths. The variable curvature fan ring frame 8 is divided into multiple non-uniform curved arc single frames arranged in sequence by the secondary support rod 9. Each non-uniform curved arc single frame is composed of a part of the outer arc edge 10, a part of the inner arc edge 11, the ring width edge 12, and / or the secondary support rod 9.

[0038] The tempered glass panel 5 includes multiple glass sub-panels 13, which are laid flat on the keel frame 4 in sequence. The joint between two adjacent glass sub-panels 13 is located on the secondary support rod 9, which provides support for the joint. The joint between adjacent glass sub-panels is filled with structural adhesive.

[0039] The tempered glass plate 5 is similar to the outer contour of the keel frame 4 in terms of the variable curvature fan ring. The tempered glass plate 5 includes an outer arc edge, an inner arc edge, and two ring width edges. The inner arc edge of the tempered glass plate 5 has the same curvature and arc length as the inner arc edge 11 of the variable curvature fan ring frame 8. The ring width edge of the tempered glass plate 5 is longer than the ring width edge 12 of the variable curvature fan ring frame 8. The curvature of the outer arc edge of the tempered glass plate 5 is the same as the curvature of the outer arc edge 10 of the variable curvature fan ring frame 8, and the arc length of the outer arc edge of the tempered glass plate 5 is greater than the arc length of the outer arc edge 10 of the variable curvature fan ring frame 8. When the tempered glass panel 5 is installed on the keel frame 4, the inner arc edge of the tempered glass panel 5 overlaps with the inner arc edge 11 of the variable curvature fan ring frame 8. The ring width edges on both sides of the inner arc edge extend beyond one end of the ring width edge 12, so that the outer arc edge of the tempered glass panel 5 is located outside the outer arc edge 10 of the variable curvature fan ring frame 8, forming a cantilever structure. This gives the tempered glass panel 5 a sense of outward expansion and depth, weakens the supporting structure of the keel frame 4, and creates a visual effect of the tempered glass panel 5 floating in the air. This makes the platform more integrated with the surrounding high-altitude environment and creates a light and graceful visual effect.

[0040] As attached Figure 5 and attached Figure 6As shown, a mounting frame 14 is also provided between the glass sub-panel 13 and the keel frame 4. The glass sub-panel 13 is fixedly connected to the mounting frame 14, and the mounting frame 14 is fixedly connected to the keel frame 4. Multiple glass sub-panels 13 and mounting frames 14 arranged sequentially completely overlap the keel frame 4, so the outer arc edge of the tempered glass panel 5 is also located outside the mounting frame 14. A metal damper 15 is also provided between adjacent mounting frames 14. The metal damper 15 is located on the side of the mounting frame 14 near the outer arc edge of the tempered glass panel 5. This metal damper 15 absorbs vibrations between adjacent glass sub-panels 13, improving the platform's earthquake and wind resistance.

[0041] As attached Figure 7 and attached Figure 8 As shown, the metal damper 15 includes an outer cylinder 16, an inner drive rod 17, and shearing rings. Each shearing ring includes an inner fixed ring 18, an outer fixed ring 19, and metal plates 20. The metal plates 20 are hourglass-shaped, narrowing inwards from both ends. There are multiple metal plates 20; in this embodiment, four metal plates 20 are provided. These four metal plates 20 are evenly distributed around the inner fixed ring 18. One end of each metal plate 20 is fixedly connected to the inner fixed ring 18, and the other end is fixedly connected to the outer fixed ring 19. The inner side of the inner fixed ring 18 is fitted over and fixedly connected to the inner drive rod 17. The outer side of the outer fixed ring 19 is fixedly connected to the inner wall of the outer cylinder 16. Multiple shearing rings are arranged sequentially along the length of the inner drive rod 17; in this embodiment, three shearing rings are provided.

[0042] The metal damper 15 located near the mounting bracket 14 has its outer cylinder 16 fixedly connected to one of the mounting brackets 14, and its inner drive rod 17 fixedly connected to its adjacent mounting bracket 14. The metal damper 15 located near the vertical extension mechanism 2 has its outer cylinder 16 fixedly connected to the vertical extension mechanism 2, and its inner drive rod 17 fixedly connected to the load-bearing structure 1.
