Description

Technical Field

[0001] The utility model belongs to the field of bridges, and in particular relates to a decorative column which can be used for improving the landscape of bridges. Background Art

[0002] Urban renewal is a crucial initiative to reshape urban space, stimulate urban vitality, and improve urban functions. It is also a key task in my country's future urban development. With the rapid development of my country's urban economy, people's expectations for the urban environment are increasing, and the aesthetics of bridge architecture are receiving increasing attention. Bridge design no longer solely considers the passage of vehicles or pedestrians; it must also be in harmony with the natural environment and cultural landscape of the bridge itself, so that it can highlight the beauty of the city.

[0003] As important transportation nodes, long-span bridges play a very important role in the landscape. Landscape design is usually based on the principle of "one bridge, one scene", focusing on the natural beauty of the bridge itself - structural beauty, which can be better realized with its own size and mechanical shape.

[0004] However, due to investment and construction constraints, small and medium-span urban bridges cannot be designed according to the "one bridge, one scene" principle. Precast beams (slabs) are often the preferred bridge type due to their favorable economic performance, ease of construction, adaptability, and ease of maintenance. These bridges have been built in significant numbers during past urbanization processes and are expected to continue in large numbers in the future. These beam bridges are straight and strong, simple and powerful, but their uniform construction also impacts the urban landscape.

[0005] In this case, the appropriate decorative structure of the bridge can soften and soothe the rigid structure, making it look rhythmic and becoming a part of people's daily living environment, different from road and railway bridges. Utility Model Content

[0006] The purpose of the utility model is to provide a decorative column that can be used to enhance the landscape of bridges, so as to solve the problem that urban bridges are all the same and have an impact on the urban landscape.

[0007] The technical solution of the utility model is: a decorative column that can be used to enhance the landscape of a bridge, wherein a column body is provided on the side of a pier and a main beam, the upper section of the column body is a semi-cylinder with a variable diameter that is wide at the top and narrow at the bottom, the lower section of the column body is a semi-cylinder, the arc surface of the column body is arranged outward, and the vertical surface of the column body is in contact with the pier and the main beam.

[0008] As a further improvement of the present invention, the top of the column body is a hollow structure, and the hollow structure serves as a flower bed.

[0009] As a further improvement of the present invention, a plurality of column bending steel bars are provided in the column body along the height direction, and the plurality of column bending steel bars are arranged along the outer contour of the column body. The lower end of the column bending steel bars extends into the pedestal, and column stirrups are provided around the column bending steel bars. The column stirrups are provided with longitudinal and transverse column horizontal tension bars.

[0010] As a further improvement of the present invention, a plurality of flower bed bending steel bars are provided along the height direction on the side walls of the flower bed, and the plurality of flower bed bending steel bars are arranged along the contour of the inner wall of the flower bed. Flower bed stirrups are provided around the flower bed bending steel bars, and the flower bed stirrups are connected to the column bending steel bars and the column stirrups through the flower bed horizontal tension bars.

[0011] As a further improvement of the present invention, the arc surface of the column body is provided with a plurality of column grooves along the height direction.

[0012] As a further improvement of the present invention, a steel wire mesh is provided at the ridges between adjacent column grooves, and the steel wire mesh is arranged along the outer contour of the ridges.

[0013] The beneficial effects of this utility model are as follows: By designing the piers and main beam sides with gradually changing semi-cylindrical columns, this utility model softens and soothes the rigid bridge structure, giving the structure a rhythmic appearance and enhancing the bridge's landscape. The utility model also incorporates a flower bed at the top of the column body, allowing for further aesthetic enhancement through the planting of plants. This utility model achieves a superior decorative effect with minimal investment without compromising the main bridge's structural load and usability, thus avoiding the overinvestment often associated with small and medium-sized bridges in pursuit of landscape effects.

[0019] The present invention will be described in detail below with reference to the accompanying drawings.

[0020] like Figure 1-4 As shown, a decorative column that can be used to enhance the landscape of a bridge is provided with a column body 1 on the side of the pier 2 and the main beam 4. The upper section of the column body 1 is a semi-cylinder with a variable diameter that is wide at the top and narrow at the bottom, and the lower section of the column body 1 is a semi-cylinder. The arc surface of the column body 1 is arranged outward, and the vertical surface of the column body 1 is in contact with the pier 2 and the main beam 4.

[0021] The top of the column body 1 is a hollow structure, and the hollow structure serves as a flower bed 11.

[0022] A plurality of column bending steel bars 13 are provided in the column body 1 along the height direction. The plurality of column bending steel bars 13 are arranged along the outer contour of the column body 1. The lower ends of the column bending steel bars 13 extend into the base 3. Column stirrups 14 are provided around the column bending steel bars 13. The column stirrups 14 are provided with longitudinal and transverse column horizontal tension bars 15.

[0023] A plurality of flower bed bending steel bars 16 are provided along the height direction on the side wall of the flower bed 11. The plurality of flower bed bending steel bars 16 are arranged along the inner wall contour of the flower bed 11. Flower bed stirrups 17 are provided around the flower bed bending steel bars 16. The flower bed stirrups 17 are tied and connected with the column bending steel bars 13 and the column stirrups 14 through the flower bed horizontal tension bars 18.

[0024] The arc surface of the column body 1 is provided with a plurality of column grooves 12 along the height direction. The ridges 19 between adjacent column grooves 12 are provided with steel mesh sheets 191 , which are arranged along the outer contour of the ridges 19 .

[0025] The top of the flower bed 11 is flush with the base of the sidewalk railing outside the main beam 4.

[0026] The column body 1 is cast with concrete of a grade not less than C30. It is a deformed body of a cylinder. With the center line of the facade of the pier as the rotation axis and the curve of the wide-mouthed vase as the main line, it rotates 180° to form an inverted "gall vase" shape that is narrow at the bottom and wide at the top. The cross-section of the column body 1 is semicircular. The semicircular diameter of the column body 1 is required to be not less than the width of the pier 2 to ensure that the pier 2 is completely blocked from the side view of the bridge. The column body 1 is cast with a steel formwork with grooves to form column grooves 12 arranged at intervals, which increases the arc changes on the outer surface of the column body 1, making it aesthetically pleasing, and can also be used as installation slots for decorative light strips. In order to prevent the concrete of the ridges 19 between the column grooves 12 from cracking, a steel mesh 19 is arranged along the edge of the ridges 19.

[0027] The top of the column body 1 is tied to an inner formwork to form a cavity, into which concrete is poured to form a flower bed 11. Flower bed 11 is at least 1 meter deep and filled with planting soil, meeting the soil depth requirements for flower planting. The wall thickness of flower bed 11 must be able to withstand internal soil pressure while also meeting the requirements for reinforcement arrangement and minimum cover thickness.

[0028] The column body 1 is connected to the pedestal 3 through the column bending steel bars 13. The column bending steel bars 13 are evenly arranged along the outer contour of the column body 1 to resist the bending moment generated by the deadweight of the column body 1 and external forces. In order to ensure the reliability and stability of the connection of the column body 1, the bending steel bars 13 should be extended into the bottom of the pedestal as much as possible and tied with the pedestal steel bars. Column stirrups 14 are arranged around the bending steel bars 13 to provide the shear bearing capacity of the column body 1 to resist the axial deformation of the concrete of the column body 1, and the two are tied to form a column steel skeleton; transverse and longitudinal column horizontal tension bars 15 are arranged inside the column stirrups 14 to improve the integrity of the column steel skeleton. The column steel skeleton is arranged along the entire length of the column body 1.

[0029] The flower bed 11 is filled with planting soil. Under the action of soil pressure, the inner wall of the flower bed 11 will be subjected to bending moments and shear forces caused by lateral pressure. Therefore, the flower bed bending reinforcement 16 is evenly arranged on the inner wall of the flower bed, and flower bed stirrups 17 are arranged around it. The flower bed bending reinforcement 16 and flower bed stirrups 17 are tied together to form a net, and are tied to the column reinforcement skeleton through the flower bed horizontal tie bars 18.

[0030] The utility model has the advantages of simple structure, convenient construction, safety and reliability, and can achieve good decorative effect with relatively low investment without affecting the stress of the main bridge structure.
