Railway bridge wind barrier

Abstract

The present invention discloses a railway bridge wind barrier, which relates to the technical field of railway bridge wind resistance, including prefabricated walls, limit frames and wind screen units. The present invention buffers the strong wind thrust borne by the main rubber columns on the horizontal main wind screen plate, the inclined rubber columns on the inclined wind screen plate and the horizontal support plates on the horizontal support wind screen plate. Since the horizontal main wind screen plate, the inclined wind screen plate and the horizontal support wind screen plate are separated from each other, they can independently buffer the strong wind thrusts of different angles and directions. In addition, the horizontal main wind screen plate and the inclined wind screen plates on both sides form a channel for strong wind to pass through. The inclined wind screen plates on both sides can buffer the side force of the strong wind, and the strong wind is discharged through the upper part thereof, reducing the impact of the strong wind on the train. In addition, the spring of the buffer component can buffer the horizontal main wind screen plate, the inclined wind screen plate and the horizontal support wind screen plate again when strong wind comes, so as to avoid damage from strong wind.

Technical Field

[0001] The present invention relates to the technical field of wind resistance of railway bridges, and particularly relates to a wind barrier for railway bridges. Background Art

[0002] When building long-span railway bridges, the design of wind resistance performance is particularly important. The wind resistance performance of the bridge directly affects the safety of railway transportation. Therefore, a wind barrier is built in the strong convective wind area of the railway bridge to weaken the wind speed of the flowing wind and ensure the safety of railway transportation. Although there are also metal plates with buffer mechanisms used to achieve wind resistance, it is difficult to buffer at multiple angles when the direction angle of the strong wind blowing towards the metal plate is uncertain. Summary of the Invention

[0003] The purpose of the present invention is to provide a wind barrier for railway bridges to overcome the above-mentioned defects in the prior art.

[0004] A wind barrier for railway bridges includes a precast wall, a limit frame and a wind screen unit. The precast walls are symmetrically arranged on both sides of the railway bridge. The limit frame is detachably connected to the top of the precast wall. A number of wind screen units are evenly distributed between the limit frame and the precast wall.

[0005] Preferably, the wind screen unit includes a horizontal main board, vertical rods and buffer components. The vertical rods are located between the limit frame and the precast wall. A number of horizontal main boards are arranged from top to bottom between the two vertical rods. Oblique support plates are respectively provided at both ends of the horizontal main board. A horizontal support plate is provided at the end of the oblique support plate. The horizontal support plate is connected to the vertical rod through a buffer component. The front side of the horizontal main board is connected with a horizontal main wind screen board through a number of evenly distributed main rubber columns. The front side of the oblique support plate is connected with an oblique wind screen board through a number of evenly distributed oblique rubber columns. The front side of the horizontal support plate is connected with a horizontal support wind screen board through a number of evenly distributed support rubber columns. Ventilation holes are provided on the horizontal main wind screen board, the oblique wind screen board and the horizontal support wind screen board.

[0006] Preferably, the buffer component includes a spring, a guide rod and a fixing ring. The fixing ring is sleeved on the vertical rod and connected to the vertical rod through a screw. Connecting ears are respectively provided on both sides of the fixing ring. The guide rod is slidably connected to the connecting ears and its front end is connected to the horizontal support plate. A stop disc is provided at the rear end of the guide rod. The spring is sleeved on the guide rod and is located between the horizontal support plate and the connecting ear.

[0007] Preferably, the upper end of the vertical rod is located in the limit hole of the limit frame, and the lower end of the vertical rod is located in the positioning hole of the precast wall.

[0008] Preferably, the limit frame is in a "U" shape with the opening facing downwards, and the lower end of the limit frame is connected to the precast wall through a U-shaped bolt预埋 in the precast wall.

[0009] The present invention has the following advantages:

[0010] When the present invention is in use, the strong wind thrust borne is buffered by the main rubber columns on the horizontal main wind screen panel, the oblique rubber columns on the oblique wind screen panel and the horizontal support panels on the horizontal support wind screen panel. Since the horizontal main wind screen panel, the oblique wind screen panel and the horizontal support wind screen panel are separated from each other, they can independently buffer the strong wind thrusts of different angles and directions. In addition, the horizontal main wind screen panel and the oblique wind screen panels on both sides form a channel for strong winds to pass through. When strong winds pass through, the oblique wind screen panels on both sides can buffer the side force of the strong wind, and the strong wind is discharged through the upper part thereof, reducing the impact of the strong wind on the train. In addition, the spring of the buffer component can buffer the horizontal main wind screen panel, the oblique wind screen panel and the horizontal support wind screen panel again when strong winds come, so as to avoid damage from strong winds.
