[0002] A wind barrier is a barrier structure used to weaken the impact of wind. It is widely used in places such as bridges and elevated roads that need to withstand wind forces. Wind barriers can effectively reduce the impact of wind on vehicle driving safety and bridge structural stability, and improve the safety and durability of the transportation system. The use of wind barriers is particularly important, especially in strong wind areas or on high-altitude bridges.

[0003] At present, wind barrier structures are usually fixed on bridge guardrails or main structures. Common materials include metal, composite materials or high-strength glass.

This method not only increases the difficulty of construction but also poses a high risk to the personal safety of construction workers. This is especially true at high altitudes and in strong winds, where construction risks are further increased. Therefore, there is an urgent need for an improved beam-column bridge guardrail wind barrier structure to simplify the installation and removal process, reduce construction risks, and improve overall ease of use and safety.

[0029] Unless otherwise defined, all technical and scientific terms used herein have the same meanings as those commonly understood by those skilled in the art in the field of the present invention. The terms used in the specification of the present invention are for the purpose of describing specific embodiments only and are not intended to limit the present invention. The term "and / or" as used herein includes any and all combinations of one or more of the relevant listed items.

[0030] like Figures 1 to 5 The beam-column type bridge guardrail wind barrier structure shown includes: a beam-column mechanism 1 and a wind barrier mechanism 2.

[0031] The beam-column mechanism 1 comprises a number of evenly arranged columns 11, a number of beams 14 vertically connected to the columns 11, and connectors 16 connecting the columns 11 and the beams 14. Figure 1 、 Figure 2 As shown, the present invention connects the column 11 and the crossbeam 14 via a connector 16, which secures them. It should be noted that the connector 16 can be in a variety of forms, including bolts, welding, clamps, or a combination of these. It should also be noted that the crossbeam 14 can have a variety of shapes, including rectangular, double-layered, or multi-cavity, H-shaped, I-shaped, or corrugated.

[0032] The wind barrier mechanism 2 includes a plurality of brackets 21 extending in the same direction as the columns 11 and fixedly connected to each other, a plurality of wind-reducing plates 23 fixed between two adjacent brackets 21, and a fixing member 24 fixing the brackets 21 and the wind-reducing plates 23. Figure 1 、 Figure 2 As shown, each bracket 21 is respectively connected and fixed to each column 11. It should be pointed out here that the fixing member 24 can be in many forms, such as bolt connection, snap connection or welding, clamp or a combination of multiple different forms of connection, etc. It should also be pointed out that the windbreak plate 23 can have many shapes, such as parallel plates, curved plates, louver-shaped plates or wavy shapes. It should also be pointed out that the windbreak plate 23 can have many shapes, such as PC plates, aluminum alloy plates, composite materials or acrylic materials.

[0033] The crossbeam 14 is connected to one end of the column 11 , and the bracket 21 is connected to the other end of the column 11 .

[0034] The utility model simplifies the installation and disassembly process through the beam-column mechanism 1 and the wind barrier mechanism 2, reduces the construction difficulty and significantly improves the construction safety, especially in high altitude and strong wind environments, reduces the risk of workers operating on the outside of the bridge; through the stable frame structure of the columns 11 and the beams 14, and the reasonable distribution of the brackets 21 and the wind-reducing plates 23, the impact of wind on the bridge and vehicles is effectively weakened, and the wind resistance is enhanced; the convenient design of the connectors 16 and the fixings 24 improves the installation and maintenance efficiency and reduces maintenance costs.

[0035] In some embodiments of the present invention, the materials of the columns 11 and the brackets 21 are both HR700F. The HR700F used in the present invention has high strength and excellent impact resistance, which can effectively improve the overall stability and durability of the structure. Under high wind pressure or strong impact conditions, the high yield strength can ensure that the columns 11 and the brackets 21 are not easily deformed, thereby improving the wind resistance of the wind barrier. At the same time, the higher toughness of HR700F helps to absorb part of the energy when the vehicle hits, reduce the risk of secondary damage, and enhance the buffering effect of the guardrail. In addition, the material has good corrosion resistance and can adapt to the harsh environment of long-term exposure of the bridge to the outdoors, extending the service life of the structure and reducing maintenance costs.

[0036] In some embodiments of the present invention, the windbreak plate 23 is made of acrylic. The windbreak plate 23 is made of acrylic material, which has high transparency and can ensure that the wind barrier does not affect the driver's line of sight, thereby improving driving safety and comfort. At the same time, it has good impact resistance, maintaining structural integrity in the event of wind impact or slight collision, and enhancing durability. The lightweight design of acrylic reduces the load on the column 11 and the bracket 21, facilitating installation and maintenance. Its excellent weather resistance allows it to be exposed to the outdoor environment for a long time without aging or corrosion. In addition, acrylic has excellent processing performance and can be made into a variety of shapes to meet the functional and aesthetic requirements of the wind barrier.

[0037] like Figure 2 As shown, each crossbeam 14 comprises multiple tubes 14a. An inner sleeve 14b is nestled between each pair of tubes 14a, connecting two adjacent tubes 14a. The inner sleeve 14b securely connects adjacent tubes 14a, significantly enhancing the overall structural strength and stability of the crossbeam 14. This effectively improves the crossbeam's 14's bending and impact resistance, better dissipating vehicle impact forces, reducing the concentration of force on a single tube 14a, and extending its service life. The inclusion of the inner sleeve 14b simplifies the assembly process between the tubes 14a, improving installation efficiency and ensuring the long-term reliability of the crossbeam 14.

[0038] like Figure 2 、 Figure 5As shown, the crossbeam 14 also has end caps 15 at both ends, which are bent toward the end connected to the column 11. The end caps 15 are connected to the crossbeam 14 via inner sleeves 14b. The crossbeam 14 is designed with end caps 15 at both ends and is bent toward the end connected to the column 11. The end caps 15 are connected to the crossbeam 14 via inner sleeves 14b, which enhances the connection strength between the crossbeam 14 and the column 11, forming a stable overall frame and further improving the impact resistance of the structure. The bent structure of the end caps 15 can better disperse the impact force, preventing the crossbeam 14 from breaking when the force is concentrated, while providing a certain buffering effect to protect the safety of vehicles and personnel. The connection method of the inner sleeve 14b ensures the accuracy and firmness of the installation, simplifies the construction process, and improves the stability and durability of the overall structure.

[0039] like Figure 3 As shown, the cross section of the column 11 is H-shaped. The column 11 includes a first connecting plate 11a connected to the crossbeam 14, a second connecting plate 11b connected to the bracket 21, and a vertical plate 11e connected between the first connecting plate 11a and the second connecting plate 11b. The two ends of the column 11 are also connected to a bottom plate 11c and a top plate 11d. The structure of the utility model enables the column 11 to have good bending and torsional resistance, and can effectively withstand multi-directional forces from the crossbeam 14 and the bracket 21 while maintaining the stability of the overall structure. The H-shaped cross section provides high strength and rigidity. The connection of the vertical plate 11e allows the first connecting plate 11a and the second connecting plate 11b to form a solid whole, further improving the load-bearing capacity. The addition of the bottom plate 11c and the top plate 11d enhances the end strength of the column 11, effectively preventing structural deformation or damage caused by long-term stress.

[0040] In order to make the support capacity of the column 11 more stable, continue as follows Figure 3 As shown, the column 11 also has a plurality of reinforcing ribs 12 arranged parallel to the bottom plate 11c. The reinforcing ribs 12 effectively improve the bending and compression resistance of the column 11, can evenly distribute the pressure and impact force from the outside, and prevent the column 11 from deformation or instability due to local stress.

[0041] In order to make the structural strength of the column 11 stronger, a reinforcing plate 13 is provided between the second connecting plate 11b and the bottom plate 11c. The reinforcing plate 13, the bottom plate 11c and the second connecting plate 11b are all arranged vertically. Figure 3 、 Figure 5As shown, the provision of the reinforcing plate 13 further enhances the structural strength and stability of the bottom of the column 11. The addition of the reinforcing plate 13 can effectively disperse and transmit the external force from the bracket 21 and the wind-reducing plate 23, avoiding structural deformation or damage caused by local stress concentration. The reinforcing plate 13 is vertically arranged with the bottom plate 11c and the second connecting plate 11b to form a multi-directional support frame, which significantly improves the compressive and torsional resistance of the column 11, ensuring the durability and reliability of the overall structure under strong wind or impact conditions.

[0042] like Figure 4 As shown, bracket 21 has an H-shaped cross-section and includes a fixing plate 21a connected to column 11. Fixing plate 21a is provided with a number of cutouts 21a1, within which windbreaks 23 are fixedly connected. One end of column 11 abuts against reinforcing plate 13. Leveraging the high bending resistance and structural stability of the H-shaped cross-section, bracket 21 is more resilient against wind and impact forces. The cutouts 21a1 on fixing plate 21a facilitate the precise installation and fixation of windbreaks 23, enhancing the connection's robustness and seismic resistance, and strengthening the overall stability of the wind barrier.

[0043] In some embodiments of the present invention, Figure 2 As shown, the fixed plate 21a also has a support member 22, which includes an extension plate 22a connected to the top plate 11d and the cross beam 14, and a reinforcing beam 22b vertically connected between the extension plate 22a and the fixed plate 21a. The top plate 11d and the cross beam 14 are connected by the extension plate 22a, forming a continuous force path for the structure, significantly improving the overall bending and compressive resistance. The vertical connection of the reinforcing beam 22b further enhances the rigidity and stability of the support member 22, effectively dispersing the external loads transmitted by the wind barrier and the cross beam 14, avoiding local stress concentration, and strengthening the overall strength of the fixed plate 21a. It prevents deformation or loosening due to long-term use, thereby improving the durability and safety of the entire guardrail wind barrier.
