Description

Technical Field

[0001] The utility model belongs to the field of bridges, and in particular relates to a side decoration system for improving the landscape of beam bridges. Background Art

[0002] As an integral part of a city, the landscape design of bridges directly impacts its overall aesthetic. The coordination of bridge landscapes with specific surrounding spatial environments allows them to organically blend into their surroundings, imbuing them with distinctive local landscape elements. This imbues urban landscape design with a rich sense of development, thereby enhancing the city's overall aesthetic.

[0003] In the past, urban bridges with spans of 20 to 35 meters were often constructed using prefabricated beam (or slab) bridges, which are inexpensive, easy to construct, and highly adaptable. While this type of bridge offers advantages in areas with limited beam height and high functional requirements, its relatively fixed structure can make it monotonous in some cases, lacking variety and aesthetic appeal, making it difficult to adapt to diverse landscape requirements.

[0004] Therefore, a good bridge side decoration can help improve the aesthetics of the bridge, improve the safety and stability of the bridge, make up for the lack of visual perception, meet people's visual aesthetics and spiritual pursuits, and has positive significance in the field of urban renewal and transformation.

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

[0021] like Figure 1-7 As shown, a side decoration system for improving the landscape of a beam bridge is provided. A decorative plate 1 is provided on the side of the main beam 4, and a decorative column 2 is provided on the abutment 3. The decorative column 2 is located outside the decorative plate 1.

[0022] The decorative panel 1 is provided with a decorative panel longitudinal structural rib 12, a decorative panel stirrup 13 and a decorative panel tension rib 14. The decorative panel longitudinal structural rib 12 is arranged along the length direction of the decorative panel 1, the decorative panel stirrup 13 is arranged on the periphery of the decorative panel longitudinal structural rib 12, and the decorative panel tension rib 14 is arranged along the thickness direction of the decorative panel 1. The decorative panel tension rib 14, the decorative panel longitudinal structural rib 12 and the decorative panel stirrup 13 are tied and connected.

[0023] The decorative panel 1 is arranged on the abutment 3 via a support system 6 .

[0024] The support system 6 includes a plate rubber support 61, oil felt 62 and a mortar leveling pad 63 which are arranged in sequence from top to bottom.

[0025] The decorative column 2 is provided with decorative column vertical steel bars 21, decorative column stirrups 22 and decorative column tension bars 23. The decorative column vertical steel bars 21 are arranged along the height direction of the decorative column 2, the decorative column stirrups 22 are arranged on the periphery of the decorative column vertical steel bars 21, and the decorative column tension bars 23 are arranged along the thickness direction of the decorative column 2. The decorative column vertical steel bars 21, decorative column stirrups 22 and decorative column tension bars 23 are tied and connected.

[0026] Example 1

[0027] During prefabrication, abutment 3 was symmetrically extended 57.5cm beyond the bridge edge in the transverse direction to reserve installation space for the decorative system. Decorative column 2 uses a solid concrete rectangular cross-section with a cross-sectional dimension of 170×80cm (longitudinal direction × transverse direction). Four columns are installed throughout the bridge, symmetrically arranged at the outermost side of abutment 3, with the exterior surface of decorative column 2 flush with abutment 3. Decorative column 2 can be cast in situ simultaneously with abutment 3, or it can be cast a second time using pre-buried steel bars. When casting decorative column 2, a 2.5cm deep groove 26 is formed on its exterior surface using decorative formwork, creating shadow differences on the concrete surface, softening and soothing the rigid structure. The capital of decorative column 2 is locally gradiented using decorative formwork to form a double-layer melon-shaped capital, giving the column a simple and exquisite shape. The decorative column 2 is connected to the abutment 3 through vertical steel bars 21. The decorative column vertical steel bars 21 are evenly arranged along the cross section of the decorative column 2, extending downward into the bottom of the abutment 3 and tied to the base steel bars. The decorative column vertical steel bars 21 extend upward to the top of the decorative column 2. Decorative column stirrups 22 are arranged around the decorative column vertical steel bars 21, and decorative column tension bars 23 are arranged at intervals inside the decorative column stirrups 22. The outer surface of the decorative column 2 has a relatively thick protective layer due to the grooves 26. To prevent concrete cracking, a column body anti-cracking steel mesh 25 is set on the surface of the decorative column 2 around the grooves 26; a column head anti-cracking steel mesh 24 is arranged on the top of the decorative column 2 at the location where the protective layer is thickened due to the corrugated pattern of the decorative column 2.

[0028] A brick retaining wall 5 is built in the space below the cantilever of the main beam 4. The outer surface of the brick retaining wall 5 is flush with the edge of the main beam 4, and the inner surface of the brick retaining wall 5 is ensured to have a gap of about 1 cm between it and the main beam 4 to ensure that the lateral deformation of the main beam 4 is not restricted. The brick retaining wall 5 not only prevents the decorative panel 1 from tilting inward, but also serves as a block for the main beam.

[0029] An arched decorative panel 1 is set between the decorative column 2 and the brick retaining wall 5. The decorative panel 1 is 33 cm thick. The bottom of the decorative panel 1 is placed on the support system 6, and the top surface of the decorative panel 1 is flush with the base of the main bridge railing. The bottom curve of the decorative panel 1 is an ellipse (or a circular curve, a parabola). The curve parameters can be adjusted appropriately according to the shape requirements without affecting the clearance under the bridge. The decorative panel 1 is arranged with decorative panel bending steel bars 11 on the bottom surface and supporting section along the longitudinal direction to withstand the bending moment caused by its own weight; the decorative panel longitudinal structural bars 12 are evenly arranged along the cross section of the decorative panel 1 at other positions to resist deformation caused by temperature changes and concrete shrinkage; decorative panel stirrups 13 are arranged around the decorative panel longitudinal structural bars 12, and are tied with the decorative panel longitudinal structural bars 12 and the decorative panel bending steel bars 11 to form a steel skeleton to resist the shear force caused by wind loads; decorative panel tension bars 14 are arranged at intervals inside the stirrups 12 in a plum blossom shape to improve the integrity of the steel skeleton. A 2.5cm deep decorative groove is provided on the exterior of the decorative panel 1. Because the decorative groove causes the protective layer to thicken locally, anti-cracking steel mesh 15 is installed around the groove to improve its crack resistance. The decorative panel 1 is prefabricated and then hoisted into place. Due to its thin-walled structure and limited lateral load-bearing capacity, the panel should be flipped over with the formwork to a vertical position after prefabrication before hoisting.

[0030] The bearing system 6 consists of a plate rubber bearing 61, a felt pad 62, and a mortar leveling layer 63. Before installation, the surface of the abutment 3 is leveled with a mortar leveling layer 63, with a thickness of at least 2 cm. After the mortar reaches the designed strength, the felt pad 62 is laid on top to protect the bottom surface of the decorative panel from moisture. Finally, the plate rubber bearing 61 is placed. The bearing system 6 transmits the bearing reaction force and deformation of the decorative panel 1.

[0031] In this embodiment, the simply supported hollow slab bridge is decorated into an arch bridge shape by means of classical decorative columns 2 and arched decorative panels 1, which makes the structure look rhythmic and reflects the structural beauty of the bridge.
