Technical Field
[0001] This utility model belongs to the field of bridge engineering, specifically relating to a column-free, arched, semi-enclosed sky bridge canopy. Background Technology
[0002] As an important component of urban pedestrian spaces, pedestrian overpasses play a vital role in alleviating traffic congestion, dispersing pedestrian flow, and providing a safe and comfortable travel environment for pedestrians. With the acceleration of urbanization, their construction is constantly increasing.
[0003] With the rapid development of my country's urban economy, people's demands for the urban environment are increasing. Overpass design no longer only considers the passage requirements of pedestrians, but also needs to start from the details and carry out humanized design to improve residents' quality of life and happiness.
[0004] As an important component of urban transportation facilities, overpass canopies provide protection for pedestrians, shielding them from the effects of severe weather in rain and snow, and safeguarding the health of citizens. They can also transform overpasses into recreational spaces where citizens can rest, chat, or observe the scenery, enriching their cultural lives. Furthermore, as part of the urban space, their unique shapes and sizes can enrich the spatial layers of the city, making the urban space more three-dimensional and profound, thus representing an important aspect of human-centered design.
[0005] In this context, there is an urgent need to research a canopy structure that is easy to construct, simple in construction, safe and reliable, and aesthetically pleasing, in order to meet the requirements of human-centered design for urban pedestrian overpasses. Utility Model Content
[0006] The purpose of this utility model is to provide a column-free, arc-shaped, semi-enclosed pedestrian bridge canopy to solve the problem that existing pedestrian bridges do not have canopies and cannot provide more convenience for pedestrians.
[0007] The technical solution of this utility model is: a column-free, arc-shaped, semi-enclosed sky bridge canopy, with an arc-shaped canopy frame and canopy keel above the main beam of the sky bridge. The canopy keel is arranged at intervals along the longitudinal direction of the bridge. No canopy keel is set at the connection between the sky bridge and the stairway. The canopy keel is set on both sides of the stairway. The canopy frame and canopy keel are covered with canopy panels. Connecting units are set on both sides of the main beam of the sky bridge. The connecting units are arranged at intervals along the longitudinal direction of the bridge. The two ends of the canopy keel are installed on both sides of the main beam through the connecting units. The two ends of the canopy frame are directly connected to the two sides of the main beam.
[0008] As a further improvement of this utility model, the canopy frame and each canopy keel are connected as one unit by longitudinal beams, and no longitudinal beams are set at the connection between the overpass and the stairway.
[0009] As a further improvement of this utility model, the connecting units are connected as one unit by longitudinal connecting parts.
[0010] As a further improvement of this utility model, a decorative panel is provided on both the outer side of the connecting unit and the outer side of the lower end of the canopy frame.
[0011] As a further improvement of this utility model, decorative tubes are provided between adjacent canopy keels and between the canopy door frame and adjacent canopy keels.
[0012] As a further improvement of this utility model, the canopy panel is made of acrylic sheet.
[0013] The beneficial effects of this utility model are:
[0014] 1. This utility model designs an arc-shaped semi-enclosed pedestrian bridge canopy, employing a column-free structure. This eliminates the need for columns within the width of the pedestrian bridge, does not encroach on its effective clear width, and does not obstruct pedestrians' view, giving a bright and spacious feel. The soaring arch design avoids a sense of oppression, allowing people to have a more pleasant experience when crossing the pedestrian bridge.
[0015] 2. The canopy panels are made of acrylic sheets with good light transmission, which can not only shelter pedestrians from wind and rain, but also not affect the lighting under the bridge, providing good visual conditions.
[0016] 3. This utility model softens and soothes the rigid structure of the overpass, making the overall structure of the overpass look rhythmic and enhancing the landscape of the bridge. Attached Figure Description

[0022] The present invention will now be described in detail with reference to the accompanying drawings.
[0023] Example 1
[0024] like Figure 1-3 As shown, a column-free, arc-shaped semi-enclosed skybridge canopy has an arc-shaped canopy frame 42 and a canopy keel 41 above the main beam 1 of the skybridge. The canopy keel 41 is arranged at intervals along the longitudinal direction of the bridge. The canopy keel 41 is not set at the connection between the skybridge and the stairway. The canopy keel 41 is set on both sides of the stairway. The canopy frame 42 and the canopy keel 41 are covered with canopy panels 44. Connecting units 31 are provided on both sides of the main beam 1 of the skybridge. The connecting units 31 are arranged at intervals along the longitudinal direction of the bridge. The two ends of the canopy keel 41 are installed on both sides of the main beam 1 through the connecting units 31. The two ends of the canopy frame 42 are directly connected to the two sides of the main beam 1.
[0025] The canopy frame 42 and each canopy keel 41 are connected as one unit by longitudinal beams 43. No longitudinal beams 43 are installed at the connection between the overpass and the stairway.
[0026] Each connecting unit 31 is connected as one unit by a longitudinal connecting member 32.
[0027] A decorative panel 33 is provided on the outer side of the connecting unit 31 and the lower outer side of the canopy frame 42. The lower end of the decorative panel 33 extends to connect with the main beam 1.
[0028] Decorative tubes 46 are provided between adjacent canopy keels 41 and between canopy door frame 42 and adjacent canopy keels 41.
[0029] The canopy panel 44 is made of acrylic sheet.
[0030] The main beam 1 is a closed welded steel box girder, prefabricated in sections in the factory and then hoisted and welded in sections on site. The beam is 1.3m high and 3.3m wide. The cantilever and web of the main beam 1 serve as supporting components for the welding of the connecting unit 31. The welded main beam 1 and the connecting unit 31 are used as a whole for the installation of the canopy.
[0031] Connecting unit 31 is the structure that connects the main beam 1 and the canopy, and also serves as the supporting structure for the canopy. The longitudinal spacing of connecting units 31 is 75cm, and they are constructed from 80×80×4mm hot-dip galvanized square steel tubing welded into an F-shaped frame. Figure 4 As shown. The longitudinal connectors 32 are also made of 80×80×4mm hot-dip galvanized square steel pipes, welded together with each connecting unit 31. The longitudinal connectors 32 are set at the welding nodes of the connecting units 31 to form a steel pipe skeleton. In order not to affect the structural shape of the main beam 1, a 3.0mm thick decorative panel 33 is placed on the outside of the steel skeleton formed by the connecting units 31 and the longitudinal connectors 32. The decorative panel 33 is made of aluminum single panel, and the inside is fixed to the connecting unit 31 by connecting bolts. The outer surface is sprayed with fluorocarbon paint to ensure that the color of the decorative panel 33 is coordinated with the overall color of the overpass.
[0032] The canopy frame 41 is the main load-bearing component of the canopy. It is made of 80×80×4mm hot-dip galvanized square steel tubing, with a single piece length of 11278mm. It is bent into a circular curve with a radius of 2550mm. To ensure its durability, the surface coating must not be damaged during the bending process, and the surface must be bright and aesthetically pleasing. The lower part of the canopy frame 41 is welded to the connecting unit 31, and its circular curve is tangent to the outer side members of the connecting unit 31, ensuring a smooth and unobtrusive appearance. The canopy frames 41 are evenly distributed along the bridge direction at 1.5m intervals.
[0033] At the junction of the main beam 1 and the stairway, to ensure sufficient clearance for passage on both the upper and lower bridges, the canopy keel 41 is replaced with a canopy gantry 42, with the spacing increased to 3.5m. Simultaneously, the connecting unit 31 and longitudinal connector 32 at this location are removed. The canopy gantry 42 uses H200×200×12×12mm steel, with a single piece length of 14188mm, and its bottom is welded to the bottom plate and web of the main beam 1. To maintain consistency with the canopy keel 41 in appearance, the canopy gantry 42 is bent into a combination of "circular curve + straight line." The portion below the bridge deck uses a straight line, consistent with the outer members of the connecting unit 31; the upper part is bent into a circular curve with a radius of 2490mm, and its outer surface is flush with the canopy keel 41. The outer surface of the straight section of the canopy frame 42 is covered with a 3.0mm thick decorative panel 33. The decorative panel 33 is made of aluminum single plate and is fixed to the canopy frame 42 on the inside by connecting bolts. The outer surface is sprayed with fluorocarbon paint to ensure that the color of the decorative panel 33 is coordinated with the overall color of the overpass.
[0034] To improve the overall integrity and stability of the bridge's canopy frame 41 and canopy portal frame 42, longitudinal beams 43 are installed on their inner sides to connect them. The longitudinal beams 43 are made of ∅97x4 hot-dip galvanized round steel pipes, running the entire length of the bridge, interrupted only at the junction of the main beam 1 and the stairway. The longitudinal beams 43 extend 1.5m above the top surface of the main beam 1. The longitudinal beams 43 are welded to the inner surface of the canopy frame 41. When intersecting with the canopy portal frame 42, a pre-drilled hole is made at the waist of the canopy portal frame 42, allowing the longitudinal beams 43 to pass through and be welded.
[0035] Decorative tubes 46 with spatial curves are welded between adjacent canopy joists 41. These tubes are irregularly arranged in a crisscross pattern and are located on the same spatial column surface as the canopy joists 41. The irregular arrangement of the decorative tubes 46, combined with the regular arrangement of the canopy joists 41, presents a layered and subtly revealing aesthetic. Decorative tubes 46 with spatial curves are also welded between the canopy frame 42 and adjacent canopy joists 41, arranged at an angle. The decorative tubes 46 are made of ∅97×4mm hot-dip galvanized round steel pipes.
[0036] The outer surface of the canopy keel 41 and canopy gate frame 42 above 1.5m on the top surface of the main beam 1 is covered with an acrylic canopy panel 44. On rainy days, this provides shelter for pedestrians from wind and rain without affecting the lighting under the bridge, ensuring good visibility. The canopy panel 44 is only installed at the top, allowing for ample ventilation on both sides to prevent stuffiness. The acrylic sheet is 20mm thick and uses reinforced acrylic material, meaning nylon strips are filled inside the acrylic sheet. This enhances its mechanical properties and stability, and under lighting, the nylon strips reflect light, creating a photoelectric effect that makes it more visually appealing. The canopy panel 44 is processed at high temperature in the factory to form an arc shape, fitting snugly against the cylindrical curve formed by the canopy keel 41. It is then fixed to the canopy keel 41 and canopy gate frame 42 using canopy mounting clips 45.
[0037] This utility model provides a pedestrian overpass canopy structure that is easy to construct, simple in structure, safe and reliable, and low in cost. It ensures a dry and comfortable crossing environment while giving the overpass a sense of quality and ceremony with its unique shape.
