Abstract
Description
Technical Field
[0001] This utility model relates to the field of bridge engineering technology, specifically to a type of under-deck pedestrian bridge. Background Technology
[0002] With the acceleration of urbanization, pedestrian bridges, as an important component of infrastructure, are receiving increasing attention not only for their transportation function but also for their aesthetics, structural safety, and ease of maintenance. Common bridge types include arch bridges, truss bridges, cable-stayed bridges, and simply supported beam bridges. Each type has its unique applicable scenarios and technical advantages, but also certain limitations.
[0003] Beam bridges, as the most common type of bridge, are simple in structure and inexpensive, but lack design innovation and artistic expression, making it difficult to meet the dual demands of modern cities for aesthetics and functionality. Truss bridges, while able to express different shapes through variations in the upper truss, have complex structures and large web members that can easily obstruct the view from a distance, appearing heavy and cluttered, giving an overly industrial feel. The limited structural elements and morphological variations of truss bridges make it difficult to harmonize with the surrounding landscape and environment, impacting the aesthetic effect. Arch bridges, with their arched structures occupying a large visual space in the landscape and massive arch foundations, restrict the height of roads or sidewalks on both banks, especially in bridges spanning rivers or urban areas, affecting traffic flow. Furthermore, their relatively fixed structural forms make it difficult to express the dynamic and streamlined design required by modern bridges, resulting in limited morphological variations and failing to meet the diverse aesthetic demands of bridge construction.
[0004] Therefore, a new pedestrian bridge structure needs to be designed to effectively improve its aesthetics and structural safety. Utility Model Content
[0005] The purpose of this utility model is to provide a bottom-bearing pedestrian bridge that combines aesthetics and structural safety, so as to better meet the development needs of pedestrian bridges.
[0006] To achieve the above objectives, this application provides a bottom-bearing pedestrian bridge, comprising:
[0007] The main bridge component includes a main beam, a bridge deck, and at least two tie rods. The bridge deck is located above the main beam, and the at least two tie rods are arranged in parallel at intervals on both sides of the bottom surface of the main beam, and the tie rods are detachably connected to the main beam.
[0008] Two bridge substructures are respectively disposed at both ends of the main beam. Each bridge substructure includes a pile foundation and a pile cap. The pile cap is fixedly connected to the top surface of the pile foundation, and both ends of the main beam are fixedly connected to one of the pile caps. Both ends of the tie rod are fixedly connected to one of the pile caps.
[0009] At least one set of bridge suspension components is provided, with the bridge suspension components provided on at least one side of the main beam. The bridge suspension components include an arch rib, two piers, and multiple hangers. The two piers are respectively fixedly connected to the top surface of a pier cap. The arch rib is erected on the top of the bridge deck, and both ends of the arch rib are respectively fixedly connected to the upper part of one of the piers. The multiple hangers are spaced apart between the arch rib and the main beam. The hangers extend vertically, and both ends of the hangers are detachably connected to the arch rib and the main beam, respectively.
[0010] As a preferred technical solution, the under-bearing pedestrian bridge further includes multiple mounting frames, which are symmetrically arranged at intervals on both sides of the bottom surface of the main beam. Each mounting frame has at least one connector inside, which defines a limiting space with the inner wall of the top surface of the mounting frame. Both ends of the mounting frame have openings, and the tie rod is detachably connected to the connector through the openings, with the tie rod located within the limiting space.
[0011] As a preferred technical solution, the connecting member is a pulley, and the tie rod is detachably connected to the pulley.
[0012] As a preferred technical solution, the bridge suspension assembly further includes multiple ear plates, which are spaced apart on the bottom surface of the arch rib and the side of the main beam. The suspension rod is detachably connected to the arch rib and the main beam through the ear plates.
[0013] As a preferred technical solution, the bridge suspension assembly is provided in two sets, and the two sets of bridge suspension assemblies are arranged in parallel at intervals on both sides of the main beam.
[0014] As a preferred technical solution, the bridge suspension assembly further includes multiple cross braces, which are spaced apart between the two sets of bridge suspension assemblies, and both ends of the cross braces are fixedly connected to an arch rib.
[0015] As a preferred technical solution, the under-bearing pedestrian bridge further includes decorative wings, which are disposed on the arch rib and are detachably connected to the arch rib.
[0016] As a preferred technical solution, the under-bearing pedestrian bridge also includes a canopy, which is disposed on the arch rib and is detachably connected to the arch rib.
[0017] As a preferred technical solution, the main beam is a steel box girder, the arch rib is a steel arch rib, and the arch rib is welded to the pier column.
[0018] The advantages of the under-deck pedestrian bridge provided by the above technical solution compared with the prior art are as follows:
[0019] 1. Replacing the traditional arch rib and arch seat structure with an arch rib and pier structure occupies less area and has less visual obstruction, which helps to improve the load-bearing capacity and aesthetics of the bridge.
[0020] 2. The arch ribs are not directly connected to the road surface, which avoids restrictions on road traffic and allows for a higher passage height on both sides of the pedestrian bridge, which helps to reduce traffic bottlenecks;
[0021] 3. Arch ribs can provide support for the installation of structures such as decorative wings or canopies, eliminating the need for separate support structures and improving the aesthetics and functionality of the bridge. Attached Figure Description

[0035] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit its scope.
[0036] Please see Figure 1-6 The present application provides a type of under-bearing pedestrian bridge, comprising: a bridge main component 1, the bridge main component 1 including a main beam 11, a bridge deck 12 and at least two tie rods 13, the bridge deck 12 being disposed above the main beam 11, and at least two tie rods 13 being disposed in parallel at intervals on both sides of the bottom surface of the main beam 11, and the tie rods 13 being detachably connected to the main beam 11;
[0037] Two bridge substructures 2 are respectively disposed at both ends of the main beam 11. Each bridge substructure 2 includes a pile foundation 21 and a pile cap 22. The pile cap 22 is fixedly connected to the top surface of the pile foundation 21, and both ends of the main beam 11 are respectively fixedly connected to a pile cap 22. Both ends of the tie rod 13 are respectively fixedly connected to a pile cap 22.
[0038] At least one set of bridge suspension components 3 is provided on at least one side of the main beam 11. The bridge suspension component 3 includes an arch rib 31, two piers 32 and multiple hangers 33. The two piers 32 are respectively fixedly connected to the top surface of a pier 22. The arch rib 31 is erected on the top of the bridge deck 12, and both ends of the arch rib 31 are respectively fixedly connected to the upper part of a pier 32. The multiple hangers 33 are spaced apart between the arch rib 31 and the main beam 11. The hangers 33 extend vertically, and both ends of the hangers 33 are detachably connected to the arch rib 31 and the main beam 11.
[0039] In this embodiment, the pedestrian bridge consists of a main bridge component 1, two substructure components 2, and at least one set of suspension components 3. The main bridge component 1 includes a main beam 11, a bridge deck 12, and at least two tie rods 13. The two tie rods 13 are spaced apart and parallel on both sides of the bottom surface of the main beam 11, and are detachably connected to the main beam 11. Compared to traditional arch bridges where the tie rods 13 are arranged inside the main beam 11, this application arranges the tie rods 13 outside the main beam 11, providing greater operating space during routine inspection and maintenance, facilitating inspection and maintenance of the tie rods 13 and the main beam 11, and reducing maintenance costs and complexity. The substructure components 2 include pile foundations 21 and abutments 22. The bottom of the pier 32 and the abutment 22 are provided with corresponding foundations to ensure the structural stability of the pier 32 and the abutment 22. The bridge suspension component 3 includes an arch rib 31, two piers 32 and multiple hangers 33. The arch rib 31 and the piers 32 form a portal frame structure. The arch rib 31 is not directly connected to the road surface at both ends of the bridge deck 12, but is connected to the upper part of the pier 32, which effectively increases the passage height at both ends of the bridge deck 12. At the same time, replacing the traditional arch seat with the pier 32 reduces the overall structure's footprint, which helps to reduce visual obstruction and improve the overall aesthetics of the structure.
[0040] It is worth noting that the number of bridge suspension components 3 can be adjusted according to the actual width and length of the bridge deck 12, so as to further reduce the restriction on road traffic and improve the aesthetics of the pedestrian bridge while ensuring the structural stability of the pedestrian bridge.
[0041] Furthermore, to facilitate the connection of the tie rod 13, multiple mounting brackets 4 are spaced apart on both sides of the bottom surface of the main beam 11. Each mounting bracket 4 has at least one connector inside, which, together with the inner wall of the top surface of the mounting bracket 4, forms a limiting space 42. The mounting bracket 4 has openings at both ends, through which the tie rod 13 is detachably connected to the connector, and the tie rod 13 is located within the limiting space 42. In this embodiment, the connector is a pulley 41, and the tie rod 13 is detachably connected to the pulley 41. Mounting bracket 4 is welded to the crossbeam on the bottom surface of main beam 11. Tie rod 13 enters mounting bracket 4 through an opening at one end of mounting bracket 4 and is supported on pulley 41. It then passes through an opening at the other end of mounting bracket 4. Both ends of tie rod 13 are then fixedly connected to a support platform 22. Pulley 41 effectively supports tie rod 13, ensuring that tie rod 13 is always within the limiting space 42. This prevents tie rod 13 from shaking significantly due to external factors such as strong winds, which could affect the connection strength between tie rod 13 and support platform 22, as well as the service life of tie rod 13.
[0042] Furthermore, the bridge suspension assembly 3 also includes multiple ear plates 34, which are spaced apart on the bottom surface of the arch rib 31 and the side of the main beam 11. The hanger rod 33 is detachably connected to the arch rib 31 and the main beam 11 through the ear plates 34. The hanger rod 33 is hooked onto the ear plates 34 on the arch rib 31 and the main beam 11 respectively, which facilitates the maintenance and replacement of the hanger rod 33 in the future.
[0043] Furthermore, the bridge suspension assembly 3 is provided in two sets, which are arranged parallel to each other on both sides of the main beam 11 at intervals. The bridge suspension assembly 3 also includes multiple cross braces 35, which are spaced apart between the two sets of bridge suspension assemblies 3, and each end of a cross brace 35 is fixedly connected to an arch rib 31. The two sets of bridge suspension assemblies 3 are symmetrically arranged on both sides of the main beam 11, increasing the stability and aesthetics of the overall structure. The cross braces 35 are also provided between the two arch ribs 31 to form the two sets of bridge suspension assemblies 3 into a whole, further enhancing its structural stability.
[0044] Furthermore, the under-bearing pedestrian bridge also includes a decorative wing 5, which is disposed on the arch rib 31 and is detachably connected to the arch rib 31. The shape of the decorative wing 5 can be changed according to design requirements, and the arch rib 31 provides support and installation position for it.
[0045] Furthermore, the under-bearing pedestrian bridge also includes a canopy, which is mounted on the arch rib 31 and is detachably connected to the arch rib 31. In this embodiment, the arch rib 31 provides sufficient installation space and effective support for the canopy, eliminating the need for additional support structures. This satisfies the landscape requirements without adversely affecting the functionality of the pedestrian bridge.
[0046] Furthermore, the main beam 11 used in this application is a steel box beam, specifically assembled from split steel box beams, which facilitates both transportation and installation of the main beam 11; the arch rib 31 and the pier column 32 are both made of steel structure, and the arch rib 31 and the pier column 32 are welded together, effectively ensuring the connection strength between the two.
[0047] In summary, the under-bearing pedestrian bridge provided in this embodiment replaces the traditional arch bridge structure by combining the arch rib 31 with the pier column 32. This effectively reduces the visual and traffic impact of the arch rib 31 and the arch seat, and reduces the overall structural footprint. The arch rib 31 is not directly connected to the road surface, which effectively increases the passage height and helps to reduce traffic bottlenecks. In addition, the tie rod 13 is arranged at the bottom of the main beam 11 and is detachably connected to the main beam 11, which greatly facilitates the later maintenance work.

The scope of this application is defined by the claimed technical solution and includes other instances that would occur to those skilled in the art.
