Description

Technical Field

[0001] The present invention relates to the technical field of bridge wind protection, and in particular to a curved wind-guiding barrier. Background Art

[0002] In recent years, with the rapid development of my country's transportation industry, more and more railways and highways have been built in strong wind areas, and the safety of transportation under the action of crosswinds has attracted more and more attention. At present, setting up wind barriers is the most economical and effective wind protection measure. Commonly used wind barriers include wind-blocking barriers and wind-guiding barriers, which have been widely used in engineering.

[0003] For example, patent CN111155454A discloses a blade-type wind-guiding barrier for a railway bridge, which can divert the crosswind acting on the blade-type wind-guiding barrier to the longitudinal and vertical directions of the bridge, reduce the impact of wind load on the wind field inside the bridge, thereby increasing the safety and stability of train operation and the comfort of passengers on the train. However, this blade-type wind-guiding barrier also has disadvantages, such as the wind-shielding surface has many edges and large wind resistance, which causes the wind-guiding blades to be subjected to greater force, increases the resistance coefficient of the bridge, and increases the overall force of the bridge, especially for large-span bridges that are sensitive to lateral wind. The impact is more obvious; secondly, the area of ​​the wind-guiding surface is small, the wind-guiding effect is weak, and the folded edge structure is adopted, which has low strength and is easy to deform under strong winds. The wind-guiding blades are reinforced by their own bent ribs. Since the panel of the wind-guiding blade is relatively thin, generally only 3 to 5 mm, the structural strength is low, and the vibration is relatively strong under strong winds, which can easily cause deformation and damage of the wind-guiding blades.

[0004] Therefore, it is necessary to design a wind-guiding barrier with small wind resistance, strong wind-guiding effect and high structural strength. Summary of the invention

[0005] In view of this, the present invention aims to propose a curved wind-guide barrier. The first problem that the present application solves is that the wind-guide barrier in the prior art has large wind resistance and weak wind-guiding effect, which increases the drag coefficient of the bridge and increases the overall stress. The second problem that the present application solves is that the wind-guide blades in the prior art have low structural strength and are easily deformed under strong winds.

[0006] To achieve the above object, the technical solution of the present invention is achieved as follows:

[0007] A curved wind guide barrier is arranged on both sides of a bridge along a driving direction, characterized in that it comprises a plurality of wind guide blades, the wind guide blades are streamlined structures, the wind guide blades are fixed to the bridge through anchors, and the wind guide blades are fixed together through longitudinal connecting rods, and the longitudinal connecting rods are arranged on the driving side of the wind shield; the wind guide blades comprise a wind shield, and a plurality of air holes are arranged on the upper part of the wind shield, and the air holes are used to guide the cross wind acting on the curved wind guide barrier;

[0008] A curved plate is provided at the upper end of the wind shield, and the wind shield is used to guide the cross wind acting on the curved wind guide barrier to the oblique lower part of the bridge, and the curved plate is used to guide the cross wind acting on the curved wind guide barrier to the oblique upper part of the bridge;

[0009] The height of the curved plate is h, the height of the windshield is h2, 20%≤h1 / (h1+h2)×100%≤30%;

[0010] The curvature radius of the curved plate is R, 1m≤R≤5m.

[0011] The curved wind guide barrier described in the present application designs the wind guide blades into a streamlined structure, uses a wind deflector to guide the crosswind to the oblique lower side of the bridge, and uses a curved panel to guide the crosswind to the oblique upper side of the bridge. This design can effectively reduce wind resistance, reduce the drag coefficient of the bridge, prevent the crosswind from directly acting on the bridge surface and causing excessive lateral pressure on the bridge, reduce the impact of wind load on the bridge, and improve the stability and structural safety of the bridge.

[0012] The height ratio of the curved panel and the wind shield in the present application can effectively balance the functions of the wind guide blades, maximizing the wind guide effect and reducing wind pressure while ensuring that the wind guide blades have sufficient structural strength;

[0013] The curvature radius of the curved panel in the present application can effectively ensure the stability and uniformity of wind flow guidance, can quickly change the wind flow direction, and improve the guidance efficiency. At the same time, it will not make the structure too bulky and reduce unnecessary wind resistance.

[0014] Furthermore, the wind shield is provided with ribs, which are an integrally formed structure with the wind shield, and the ribs are used to enhance the structural strength of the wind shield; the ribs include a first rib and a second rib, the first rib is arranged at the left end of the wind shield, and the second rib is arranged at the right end of the wind shield, and the first rib and the second rib are symmetrically distributed on the left and right sides of the wind shield.

[0015] The provision of ribs can effectively enhance the structural strength of the windshield, so that the windshield can better withstand the impact of wind pressure, collision or other external forces, thereby reducing the risk of deformation, bending or damage.

[0016] Furthermore, the first rib plate includes a first long rib plate and a first short rib plate, the first long rib plate is arranged at the left end of the wind shield plate, and the first short rib plate is arranged at the left end of the first long rib plate; the second rib plate includes a second long rib plate and a second short rib plate, the second long rib plate is arranged at the right end of the wind shield plate, and the second short rib plate is arranged at the right end of the second long rib plate.

[0017] This design increases the longitudinal stiffness of the windshield, can effectively share the wind pressure of the crosswind, provide additional support on both sides of the windshield, enhance the bending resistance of the board, and prevent the windshield from bending or damage when subjected to strong winds.

[0018] Furthermore, the wind guide blade includes a stiffener, which is arranged on the running surface side of the wind shield plate, and is used to enhance the structural strength of the wind guide blade.

[0019] This design can enhance the structural strength of the wind guide blades, so that the wind shield can maintain high strength and rigidity without using overly thick materials. It not only helps to reduce the amount of material used and reduce costs, but also reduces the weight of the wind guide blades.

[0020] Furthermore, the wind guide blades are fixed by three groups of longitudinal connecting rods, and the three groups of longitudinal connecting rods are arranged in sequence from top to bottom;

[0021] The stiffener comprises a first stiffener and a second stiffener, wherein the first stiffener is located at the left end of the wind guide blade, and the second stiffener is located at the right end of the wind guide blade, and the first stiffener and the second stiffener are symmetrically distributed on the left and right sides of the wind guide blade.

[0022] This design can improve the strength of the air guide blades and prevent the air guide blades from deforming when subjected to excessive force.

[0023] Furthermore, the wind guide blades are fixed by a group of longitudinal connecting rods, and the longitudinal connecting rods are arranged at the upper part of the wind shield; the stiffening members include a first stiffening member, a second stiffening member and a third stiffening member, the first stiffening member is located at the left end of the wind shield, the second stiffening member is located at the right end of the wind shield, the first stiffening member and the second stiffening member are symmetrically distributed on the left and right sides of the wind shield, the third stiffening member is located at the upper end of the wind shield, the third stiffening member is located between the first stiffening member and the second stiffening member, one end of the third stiffening member is connected to the first stiffening member, and the other end of the third stiffening member is connected to the second stiffening member.

[0024] This design can greatly enhance the rigidity and stability of the windshield, effectively share and disperse the external load applied to the windshield, and prevent local deformation or instability.

[0025] Furthermore, the longitudinal connecting rod includes a connecting rod, a pipe clamp and a fastening screw, wherein the pipe clamp is used to fix the connecting rod on the wind guide blade, and the fastening screw is used to fix the pipe clamp and the wind guide blade together.

[0026] This design can simplify the installation steps, improve work efficiency, and facilitate production, manufacturing and maintenance.

[0027] Furthermore, the anchoring member includes a bottom plate, and an outer support plate and an inner support plate are arranged at the upper end of the bottom plate, wherein the outer support plate is located on the windward side and the inner support plate is located on the driving side;

[0028] The outer support plate and the inner support plate are both L-shaped plates. The outer support plate includes an outer vertical plate and an outer bottom plate connected together, and the inner support plate includes an inner vertical plate and an inner bottom plate connected together. The lower end of the wind shield is arranged between the bottom plate, the outer vertical plate and the inner vertical plate, and the outer vertical plate and the rib plate, the inner vertical plate and the rib plate, the outer bottom plate and the bottom plate, and the inner bottom plate and the bottom plate are all fixed together by connecting bolts.

[0030] Furthermore, the angle between the outer vertical plate and the outer bottom plate is α, 78°≤α≤88°, and the angle between the inner vertical plate and the inner bottom plate is β, 94°≤β≤110°.

[0031] The smaller angle between the outer facade and the outer base plate can improve the bending stiffness of the supporting structure, allowing the outer support plate to form a stronger angle support on the windward side, which helps to resist the bending and deformation caused by crosswinds and guide the crosswinds diagonally downward from the bridge, reducing the impact on the bridge.

[0032] Furthermore, an embedded plate is provided at the lower end of the base plate, and the base plate and the embedded plate are fixed together by anchor bolts. A plurality of groups of embedded steel bars are provided at the lower end of the embedded plate, and the embedded steel bars are used to enhance the firmness of the embedded plate.

[0033] This design enhances the stability of the base plate, prevents the base plate from loosening or displacement, and facilitates adjustment and precise installation during construction. By setting multiple groups of embedded steel bars at the lower end of the embedded plate, the tensile, compressive and shear resistance of the embedded plate can be significantly improved, thereby enhancing the stability of the entire anchoring system.

[0034] Compared with the prior art, the curved wind guide barrier of the present invention has the following advantages:

[0035] 1) The wind guide blades are designed to be streamlined, and the wind deflectors are used to guide the crosswind to the oblique lower part of the bridge, and the curved panels are used to guide the crosswind to the oblique upper part of the bridge. This design can effectively reduce wind resistance, reduce the drag coefficient of the bridge, and prevent the crosswind from directly acting on the bridge surface and causing excessive lateral pressure on the bridge, thereby reducing the impact of wind loads on the bridge and improving the stability and structural safety of the bridge;

[0036] 2) By rationally designing the height ratio between the curved panel and the wind shield, the wind guiding effect can be maximized, the wind pressure can be reduced, and the wind guiding blades can be guaranteed to have sufficient structural strength;

At the same time, the structure will not be too bulky, and unnecessary wind resistance can be reduced;

[0038] 4) By designing stiffeners, the structural strength of the wind guide blades can be enhanced, the bearing capacity of the wind guide blades can be improved, and structural damage and bending deformation of the wind guide blades caused by excessive vibration in strong winds can be avoided. The wind shield does not need to use too thick materials to maintain high strength and rigidity, which not only helps to reduce the use of materials and reduce costs, but also reduces the weight of the wind guide blades.
