Technical Field

[0001] The utility model belongs to the technical field of bridge design, and in particular relates to a space-combined suspended landscape platform unit. Background Art

[0002] As a key element in scenic areas, viewing platforms not only offer visitors a unique experience of ascending to distant horizons, but also become a significant attraction through their distinctive shape and structural design. However, with the booming tourism industry and the increasing demands of visitors for a truly immersive experience, traditional viewing platform designs are gradually showing their limitations, facing severe challenges in terms of carrying capacity, sensory experience, and structural innovation.

[0003] Currently, most viewing platforms feature a single, narrow corridor extending outward from the mountain. This monotonous design and insufficient sensory experience are pressing challenges facing these platforms. Conventional viewing platforms often lack variety and depth in their design, making it difficult to offer visitors a rich and diverse sensory experience. In the increasingly competitive tourism market, enhancing the visitor experience has become crucial for scenic area development. As key nodes in scenic areas, design innovation for viewing platforms is particularly crucial and urgent.

[0004] Therefore, in response to the above problems and challenges, the present invention aims to design a spatial combination suspended landscape platform unit. Utility Model Content

[0005] To address the challenges of existing technologies, this utility model provides a spatially combined suspended viewing platform unit. This design breaks away from the traditional planar structure and, through innovative spatial combinations, offers visitors unprecedented visual effects and a unique touring experience. Furthermore, the design fully considers requirements for load capacity, sensory experience, and structural innovation, aiming to meet the diverse needs of visitors while promoting innovation and development in scenic viewing platform design.

[0006] The utility model is realized in this way, a spatial combination suspended landscape platform unit, characterized in that: the bridge body includes a main landscape platform and a first viewing channel connected to the main landscape platform; at least one cantilevered landscape platform is provided around the main landscape platform, and the cantilevered landscape platform and the main landscape platform are not at the same horizontal height; a second viewing channel is provided between the main landscape platform and the cantilevered landscape platform.

[0007] Preferably, there are two cantilevered viewing platforms, which are distributed on both sides of the main viewing platform in a mirror-symmetrical manner.

[0008] Preferably, one of the two cantilevered viewing platforms is located above the main viewing platform, and the other is located below the main viewing platform.

[0009] Preferably, when there are two or more cantilevered viewing platforms, one of the two adjacent cantilevered viewing platforms is located above the main viewing platform, and the other is located below the main viewing platform.

[0010] Preferably, the cantilevered viewing platform is provided with a third viewing passage connected to the next main viewing platform or the cantilevered viewing platform.

[0011] Preferably, the main viewing platform includes a main viewing platform frame, and the main viewing platform frame is paved with a floor or a perspective glass plate; the main viewing platform frame is surrounded by fences or guardrails.

[0012] Preferably, the cantilevered viewing platform includes a cantilevered landscape frame, on which a floor or a perspective glass panel is laid; and the cantilevered landscape frame is surrounded by fences or guardrails.

[0013] Preferably, the fence is a transparent glass fence.

[0014] The advantages and technical effects of this utility model are as follows: This utility model is mainly reflected in the structural stability and safety, optimization of viewing experience, design flexibility and space utilization and visual effects, and the unique advantages of the cantilevered viewing platform design, providing tourists with a safer, more comfortable and pleasant viewing experience.

[0015] First, in terms of structural stability and safety, this technology significantly enhances the overall structural stability and safety of the viewing platform through the meticulously designed main frame, cantilever frame, main viewing platform support platform, and cantilever support platform. In actual construction, the cable bridge-style structure, combined with the main cable and wind-resistant cables, forms a single, force-bearing structure with the connected main components. This design effectively resists external wind pressure, visitor loads, and other forces, ensuring the stable operation of the viewing platform in various environmental conditions and safeguarding the personal safety of visitors.

[0016] Secondly, in terms of optimizing the viewing experience, the design of the main landscape enclosure and the cantilevered landscape enclosure not only provides necessary safety for visitors, but also guides visitors' sights through their unique design aesthetics, greatly enhancing the viewing experience. Furthermore, the rational layout of the first and second viewing paths allows visitors to easily reach different locations on the viewing platform and fully appreciate the diverse landscape, meeting their needs for convenience and comfort.

[0017] Furthermore, this technology offers design flexibility and space utilization, enabling the creation of a richer range of spaces. A modular design approach allows the structural form of the main frame and cantilever frame to be flexibly adjusted based on site conditions and viewing requirements. This design flexibility not only helps achieve a harmonious integration between the viewing platform and its surroundings, but also, through the rational layout of the support platform and viewing path, fully utilizes limited space resources, improves space utilization, and achieves efficient land use.

[0018] Furthermore, the use of triple-layer explosion-proof glass enhances the viewing experience. Using modern materials like triple-layer explosion-proof glass for the support platform and fencing not only meets structural safety requirements but also imbues the viewing platform with a unique perspective and suspended effect, enhancing its overall aesthetics and visual impact. This triple-layer explosion-proof glass not only enhances the viewing platform's sense of technology and modernity, but also provides visitors with a more stunning viewing experience.

[0019] The design of the cantilevered viewing platform is a highlight of this technology. By placing it on a different plane from the main viewing platform, it adds a sense of layering and spatial depth to the scenery. This design expands the viewing area, bringing visitors closer to nature and providing a broader perspective. Furthermore, the use of the cantilevered structure demonstrates the innovative nature of the structural design. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0032] Given the limited design and sensory experience of traditional viewing platforms, they are no longer able to meet the growing and diverse needs of modern tourists. Especially in the context of increasingly competitive tourism markets, innovative design of viewing platforms is particularly urgent. To this end, this utility model was created to break the constraints of conventional design through an innovative spatial combination method. The result is a spatially combined suspended viewing platform unit, designed to provide tourists with unprecedented visual effects and a unique touring experience, thereby comprehensively enhancing the attraction of scenic spots and leading a new trend in viewing platform design.

[0033] Example 1, please refer to Figures 1 to 3 A spatial combination suspended landscape platform unit, connecting the bridge body including a main landscape platform 1, a first viewing channel 2 connected to the main landscape platform; at least one cantilevered viewing platform 3 is provided around the main landscape platform. In this embodiment, one cantilevered viewing platform is provided, and the cantilevered viewing platform and the main landscape platform are not at the same horizontal height; a second viewing channel 4 is provided between the main landscape platform and the cantilevered viewing platform.

[0034] The spatial combination of the suspended landscape platform unit described above achieves multiple technical effects through its unique design layout, which are analyzed in detail as follows:

[0035] Enhanced visual hierarchy and spatial experience: The main viewing platform (1), serving as the core area, is integrated with at least one cantilevered viewing platform (3), with the two platforms at different heights. This design significantly enriches the visual hierarchy of the viewing platforms. Visitors can experience landscape perspectives from different heights as they move, adding to the fun and sense of discovery within the visit.

[0036] Enhancing viewing diversity and interactivity: The first viewing path, Path 2, connects to the main viewing platform. It not only provides access to the platform but also serves as a bridge connecting different viewing points, facilitating visitor mobility and interaction between different areas. The second viewing path, Path 4, connects the main viewing platform with the cantilevered viewing platform. This design not only ensures safe passage but also allows visitors to gradually adapt to changes in height as they move, allowing them to enjoy the scenery at different heights and enhancing the continuity and diversity of the views.

[0037] Optimizing Space Utilization and Landscape Integration: The design of the cantilevered Observation Deck 3 not only effectively utilizes space but also cleverly integrates it into the natural landscape. It allows visitors to enjoy the scenery from a closer vantage point to the natural landscape or the city skyline, enhancing the interaction between people and the environment and making the viewing experience more vivid and profound.

[0038] Example 2, please refer to Figures 4 to 6 The two cantilevered viewing platforms are mirror-imaged and arranged on either side of the main viewing platform. Visual balance and aesthetic enhancement: The mirror-image symmetry creates a sense of visual balance, making the entire viewing platform appear more harmonious and unified. This symmetry not only aligns with human aesthetic preferences but also enhances the overall beauty of the landscape, leaving a deep impression on visitors.

[0039] Enhanced Sense of Space and Flow: Two cantilevered viewing platforms flank the main viewing platform, creating an open spatial layout that allows visitors to view the scenery from multiple angles and heights. This design promotes spatial flow, encouraging visitors to move freely within the viewing platform and explore different perspectives.

[0040] Enhancing the diversity of viewing experiences: Because the two cantilevered viewing platforms are located in different locations, they offer different viewing experiences. Visitors can choose different viewing platforms based on their interests and preferences, thus enjoying a richer and more diverse viewing experience.

[0041] Increased Interaction and Social Opportunities: The mirrored, cantilevered viewing platforms offer visitors more opportunities for interaction and socializing. Visitors can move back and forth between the two viewing platforms, sharing their experiences with friends and family, making the visit more engaging and interactive.

[0042] Structural stability and safety: From a structural design perspective, the mirror-symmetrical layout helps maintain the structural stability of the entire viewing platform unit. Through reasonable mechanical design and material selection, the cantilevered viewing platform remains stable under various loads, thereby ensuring the safety of visitors.

[0043] Preferably, one of the two cantilevered viewing platforms is located above the main viewing platform, while the other is located below it. The upper one is designated as upper cantilevered viewing platform 3-1, while the lower one is designated as lower cantilevered viewing platform 3-2. This technical solution enriches spatial hierarchy: by placing one cantilevered viewing platform above the main viewing platform and the other below, the design creates a distinct spatial hierarchy. This layout not only increases viewing diversity but also allows visitors to experience different perspectives, from high to low and vice versa, making the viewing experience more vivid and interesting.

[0044] Unique landscape perspectives: Cantilevered viewing platforms above the main viewing platform offer visitors a broader view of the surrounding scenery, potentially even encompassing the distant horizon or city skyline. Cantilevered viewing platforms below, on the other hand, can bring visitors closer to the ground or water, allowing them to experience different natural elements, such as breezes and ripples, for a more intimate experience.

[0045] Enhanced Exploration and a Sense of Surprise: The design of cantilevered viewing platforms at varying heights stimulates visitors' desire for exploration. As visitors move from one viewing platform to another, they experience changes in height, which not only creates a visual impact but also a psychological sense of surprise, adding to the fun of the visit.

[0046] Adapting to Different Visitors: Visitors of different ages, physical abilities, and interests may have different preferences for viewing heights. This design can meet the needs of more visitors, whether they prefer to look down from above or appreciate the scenery from below, they can find a viewing position that suits them.

[0047] Structural Design and Challenges: From an engineering perspective, placing one cantilevered viewing platform above the main viewing platform and another below it placed higher demands on the structural design. During actual bridge construction, the load-bearing requirements were met based on the different geographical locations through the design of the main cables 6, wind-resistant cables 7, stay cables 8, support rods 9, and dampers. For example, at least two main cables and two wind-resistant cables were connected to the main viewing platform, with stay cables installed between the main cables and the wind-resistant cables. The suspended viewing platform can be connected to the support rods connected to the main cables to ensure the stability, safety, and durability of the structure. Natural factors such as wind pressure and temperature fluctuations were also considered to ensure the safety of visitors.

[0048] Preferably, when there are two or more cantilevered viewing platforms, one of the two adjacent cantilevered viewing platforms is located above the main viewing platform, while the other is located below it. This design demonstrates remarkable structural innovation through the staggered layout of multiple cantilevered viewing platforms, particularly the placement of adjacent platforms above and below the main viewing platform. This innovation not only overcomes the structural challenges posed by uneven heights, ensuring the stability and safety of the platforms, but also cleverly utilizes the height differences to provide visitors with a unique viewing experience. This breakthrough in structural design not only enhances the functionality of the viewing platforms but also strengthens their artistry and aesthetic appeal, making it a major highlight of the scenic area.

[0049] Preferably, the cantilevered viewing platform is provided with a third viewing passage 5 connected to the next main viewing platform or the cantilevered viewing platform. Preferably, in this embodiment, the upper cantilevered viewing platform is provided with the third viewing passage.

[0050] Enhanced connectivity and convenience: The existence of the third viewing channel ensures smooth connection between various viewing platforms. Whether it is the main viewing platform or the cantilevered viewing platform, visitors can easily move from one platform to another through these channels, greatly improving the convenience and smoothness of the tour.

[0051] Enhanced viewing experience: Connected viewing paths not only provide visitors with a continuous viewing path, but also make the entire tour process more coherent and interesting. Visitors can freely shuttle between different viewing platforms, enjoying the scenery at different heights and angles, thereby gaining a richer and more comprehensive viewing experience.

[0052] Adapting to terrain and distance: In actual construction, multiple viewing units can be flexibly arranged according to the shape of the mountain or the distance between the two main towers, and connected by a third viewing channel. This design allows the viewing platform to better adapt to complex terrain conditions and also provides greater flexibility for scenic area planning.

[0053] Structural stability and safety: While each cantilevered viewing platform and main viewing platform are independent structures, the connection of the third viewing channel makes the entire viewing system a more stable and secure whole. During the design and construction process, the interaction between the various platforms can be comprehensively considered to ensure the structural stability and safety of the entire system.

[0054] Preferably, the main viewing platform 1 includes a main viewing platform frame 1-1, on which a floor or a perspective glass plate (not marked in the figure) is laid; and fences 1-2 or guardrails are provided around the main viewing platform frame.

[0055] Preferably, the cantilevered viewing platform includes a cantilevered landscape frame 3-3, on which a floor or a perspective glass plate (not marked in the figure) is laid; and fences 3-4 or guardrails are provided around the cantilevered landscape frame.

[0056] Structural stability and safety of the cantilevered viewing platform and main viewing platform: The main viewing platform frame, as the supporting structure of the entire viewing platform, must be designed to ensure sufficient strength and stability to withstand external forces such as visitor loads, wind pressure, and deadweight. The stability of the frame is directly related to the safety and service life of the viewing platform.

[0057] Optimization of viewing experience: Transparent glass panels (such as tempered glass) laid on the floor allow visitors to have a wider field of view when viewing the scenery. They can even directly see the landscape under their feet, such as cliffs, gurgling water, etc., which greatly enhances the shock and immersion of viewing.

[0058] Safety protection: Fences or guardrails are important measures to ensure the safety of tourists. They can effectively prevent tourists from accidentally falling, especially at high altitudes or steep terrain. These protective facilities are particularly important.

[0059] Preferably, the fences are transparent glass fences, which not only blend harmoniously with the overall design with their streamlined appearance, but also provide solid safety protection at critical moments, allowing every visitor standing on the viewing platform to immerse themselves in the magnificent scenery before them without worries.

[0060] In terms of structural design, the main viewing platform frame, cantilevered landscape frame, main passageway, and first, second, and third passageways are preferably constructed of high-strength steel, connected by welding or bolts to form a stable framework. Steel's high strength, light weight, and corrosion resistance make it an ideal material for constructing the high-altitude viewing platform framework. During the design process, the spacing and cross-sectional dimensions of the steel beams, as well as the main cables connecting the main viewing platform framework, can be rationally arranged based on factors such as load size and wind direction and force to ensure the overall stability and safety of the framework.

[0061] The main viewing platform, cantilevered viewing platform, second and third viewing passages and first viewing passage all adopt continuous steel box girder structure, made of Q460C. The main viewing platform beam is 1.8m high, the cantilevered viewing platform beam is 1.0m high, the first viewing passage steel beam is 1.5m high, and the cantilevered beams of the second and third viewing passages gradually increase in height from 1.8 to 1.0m.
