Description

Technical Field

[0001] This utility model belongs to the field of bridge engineering, specifically relating to a decorative hanging panel for enhancing the landscape of small box girder bridges. Background Technology

[0002] Urban renewal is an important measure to reshape urban space, stimulate urban vitality, and improve urban functions. It is also one of the important tasks for urban construction in my country in the future. With the rapid development of my country's urban economy, people's requirements for the urban environment are increasing. The aesthetics of bridge architecture are receiving more and more attention. Bridge design no longer only considers the traffic requirements of vehicles or pedestrians, but also needs to be in harmony with the natural environment and cultural landscape of the bridge itself, so that the bridge can highlight the beauty of the city.

[0003] Long-span bridges, as important transportation nodes, play a very important role in the landscape. They are usually designed according to the principle of "one bridge, one view", which focuses on highlighting the natural beauty of the bridge itself - structural beauty, which can be well realized through its own size and mechanical shape.

[0004] However, due to limitations in investment and construction conditions, urban bridges with small to medium spans cannot be designed according to the principle of "one bridge, one view." Precast beams, which offer good economic indicators, are easy to construct, adaptable, and easy to maintain, are often the preferred bridge type. A vast number of these bridges have been built during past urbanization processes and are expected to continue to be widely used in the future. While these beam bridges are straight, rigid, simple, and powerful, their uniform structural form also negatively impacts the urban landscape.

[0005] In this context, well-designed bridge decorations can soften and soothe the rigid structure, giving it a rhythmic feel and making it a part of people's daily environment, distinguishing it from highway and railway bridges. Utility Model Content

[0006] The purpose of this invention is to provide a decorative hanging panel for enhancing the landscape of small box girder bridges, in order to solve the problem of how to improve the landscape level of bridges.

[0007] The technical solution of this utility model is: a decorative hanging panel for landscape enhancement of small box girder bridges. The decorative hanging panel is set on both sides of the bridge body along the longitudinal direction of the bridge. The decorative hanging panel includes a panel, a steel frame and embedded parts. Multiple reserved steel bars are provided on the back of the panel. The panel is welded to the steel frame through the reserved steel bars. Multiple embedded parts are provided. The embedded parts are embedded in the box girder of the bridge body. The steel frame is welded to the embedded parts.

[0008] As a further improvement of this utility model, the embedded part is made of embedded steel bars and embedded steel plates welded together. The embedded steel bars are tied to the steel reinforcement skeleton of the box girder, the outer surface of the embedded steel plate is exposed above the web of the box girder, and the steel skeleton is welded to the outer surface of the embedded steel plate.

[0009] As a further improvement of this utility model, the pre-embedded steel bars are made of ring-shaped ribbed bars.

[0010] As a further improvement of this utility model, the outer surface of the embedded steel plate does not protrude from the concrete surface of the box girder.

[0011] As a further improvement of this utility model, the panel is bent, forming a structure with alternating concave and convex sections.

[0012] As a further improvement of this utility model, a lighting strip is provided on the outer surface of the panel.

[0013] As a further improvement of this utility model, the lighting strip is set in the recessed part of the outer surface of the panel.

[0014] As a further improvement of this utility model, a corbel is provided on the side of the pier cap beam, and the corbel is connected to the bottom of the panel.

[0015] The beneficial effects of this utility model are as follows: This utility model, through its simple structure, easy construction, and reliable safety, uses decorative panels to soften and soothe the rigid structure, giving it a rhythmic appearance and enhancing the bridge's aesthetic appeal. This utility model achieves a good decorative effect with minimal investment without affecting the main bridge's structural load-bearing capacity or functionality, avoiding excessive investment in small and medium-sized bridges due to the pursuit of aesthetic appeal.

[0020] The present invention will now be described in detail with reference to the accompanying drawings.

[0021] Example 1

[0022] like Figure 1-3As shown, a decorative panel for landscape enhancement of a small box girder bridge is provided. The decorative panel 4 is set on both sides of the bridge body along the longitudinal direction of the bridge. The decorative panel 4 includes a panel 43, a steel frame 42 and embedded parts 41. Multiple reserved steel bars 44 are provided on the back of the panel 43. The panel 43 is welded to the steel frame 42 through the reserved steel bars 44. Multiple embedded parts 41 are provided. The embedded parts 41 are embedded in the box girder 1 of the bridge body. The steel frame 42 is welded to the embedded parts 41.

[0023] The embedded part 41 is made of embedded steel bars 411 and embedded steel plates 412 welded together. The embedded steel bars 411 are tied to the steel reinforcement skeleton of the box girder 1 to ensure that the embedded part 41 is firmly connected to the box girder 1. The embedded steel plate 412 is a 150×150×10mm rectangular steel plate. Its outer surface is exposed above the web of the box girder 1, but does not protrude from the concrete surface of the box girder 1. The steel skeleton 42 is welded to the outer surface of the embedded steel plate 412.

[0024] The embedded steel bar 411 is a 12mm diameter ring-shaped ribbed bar.

[0025] The outer surface of the embedded steel plate 412 does not protrude from the concrete surface of the box girder 1.

[0026] Panel 43 is bent, forming a structure with alternating concave and convex sections, which can effectively improve its resistance to deformation.

[0027] The outer surface of panel 43 is provided with a lighting strip 45.

[0028] The lighting strip 45 is set in the recessed part of the outer surface of the panel 43.

[0029] A corbel 21 is provided on the side of the pier cap beam 2. The corbel 21 extends 80cm beyond the outer surface of the pier cap beam 2 in the transverse direction and is the same width as the pier cap beam 2 in the longitudinal direction. The bottom surface is flush with the bottom of the pier cap beam 2. The corbel 21 is connected to the bottom of the panel 43 and plays a supporting role for the panel 43.

[0030] Box girder 1 is prefabricated in the factory, and the pre-embedded parts 41 are installed simultaneously during the prefabrication of its side beams. The pre-embedded parts 41 are arranged longitudinally along the bridge with a spacing of 1m, with 4 parts at each location, located on the outer side of the cantilever and web of box girder 1. During installation, a level instrument must be used for precise positioning to ensure that the 4 pre-embedded steel plates 412 are located on the same vertical plane.

[0031] The steel frame 42 is the load-bearing component of the decorative panel 4, used to fix and support the panel 43, achieving fixation and wind protection through its own load-bearing capacity. The steel frame 42 is welded from 40×40×2.5mm square tubes with good bending resistance and light weight. According to the arrangement direction, it is divided into vertical tubes, horizontal tubes, and longitudinal tubes, which intersect in three directions to form a beam grid system. Among them, the horizontal and vertical tubes are welded to form the beam grid surface, which is arranged at intervals in the longitudinal direction of the bridge and welded to the embedded parts 41. The welded beam grid surface is connected into a whole by the longitudinal tubes, which are arranged along the longitudinal length of the bridge and welded to the outer vertical tubes to form the base surface for installing the panel 43.

[0032] Panel 43 is a component used to achieve the landscape effect of decorative hanging panels 4. It is arranged on the outer side of the steel frame 42 and is connected to the steel frame 42 as a whole through reserved steel bars 44. Panel 43 is made of stainless steel and is 15mm to 30mm thick. The top surface of the decorative panel 43 is flush with the bottom surface of the cantilever of the box girder 1, and the bottom curve is elliptical (or circular curve, parabola). Without affecting the clearance under the bridge, the curve parameters can be appropriately adjusted according to the design requirements to present the desired landscape effect. By adjusting the vertical length of panel 43, the concave and convex aspects of panel 43 gradually change along the longitudinal direction of the bridge, which softens and soothes the rigid structure. Illuminated light strips 45 are installed on the bent surface of panel 43. The light will reflect and refract on the curved surface, producing a variety of light and shadow effects.

[0033] In this embodiment, the bridge railing 3 is designed as a stainless steel landscape railing, which is used in conjunction with the hanging plate 4 to achieve a landscape effect.
