Vertical plate type wind barrier of railroad bridge

Abstract

The invention discloses a vertical plate type wind barrier of a railroad bridge, the vertical plate type wind barrier comprises pre-embedded assemblies pre-embedded in a bridge vertical wall and a curtain board, wind shielding vertical plates distributed in an array and cross rods, the wind shielding vertical plates extend along the direction of a railway track, and wind shielding flat plates are arranged between the wind shielding vertical plates; a first fixing bolt is arranged on the cross rod, the first fixing bolt sequentially penetrates through the cross rod, the wind shielding flat plate and the wind shielding vertical plate to be fixed, and a second fixing bolt is arranged between the wind shielding vertical plate and the wind shielding flat plate; the wind shielding vertical plate comprises a bottom plate, the embedded assembly comprises U-shaped anchor bolts, locking nuts and leveling nuts, the U-shaped anchor bolts, the locking nuts and the leveling nuts are symmetrically distributed on the bottom plate, the locking nuts and the leveling nuts are located on the U-shaped anchor bolts, and the locking nuts and the leveling nuts are located on the two sides of the bottom plate respectively. The vertical plate type wind barrier is formed by splicing the multiple pre-embedded assemblies, the multiple wind shielding vertical plates, the wind shielding flat plates and the transverse rods, and has the advantages of being light in structure self weight, convenient to install, good in bending resistance and good in wind shielding performance.

Description

Technical field [0001] The present invention relates to the field of railway bridges, and is specifically a standing wind barrier of a railway bridge. Background technique [0002] With the continuous improvement of the operation speed of the high-speed railway train, the impact of strong side-on-side fees is more highlighted. The railway wind barrier is a device that reduces the pneumatic power of the rail train in the horizontal wind, by setting a wind barrier to ensure that the train can safely travel safely under high wind climate. At present, the main effective measures that are widely taken at home and abroad are to build a windshield or wind grille in the wind zone. [0003] At present, the railway bridge is mainly based on the grid structure wind barrier. The engineering example shows that the structure is small in the region, its windshield and its own anti-winding ability are sufficient; but for the construction of the Yamou Canyon Regions, as well as a variable region ...

AI Technical Summary

Problems solved by technology

[0003] At present, the grid structure wind barriers are mainly used on railway bridges. Engineering examples show that the wind-shielding performance and wind resistance of this structure are sufficient in areas with small wind loads; areas, as well as areas with drastic changes in airflow such as offshore, the wind barrier has obvious limitations
