Fixed connection structure used for high speed railway sound barrier transparent cell boards

Abstract

The invention provides a fixed connection structure used for high speed railway sound barrier transparent cell boards, belonging to the field of railway components. The structure comprises a sound barrier 1, a main buffering sealing joint strip 2, an aluminium alloy section frame 3, a side buffering sealing joint strip 4, an aluminium alloy bracket 5, a steel angle plate 6, a steel angle plate pulling plate 7 and an aluminium rivet 8, wherein the aluminium alloy section frame 3 is provided with a groove 31, a long groove 33, a side groove 34, a side hole 35 and a rectangle center hole 36; a wall board 32 is arranged under the aluminium alloy section frame; the groove 31 is used for placing the main buffering sealing joint strip and then placing the sound barrier; the long groove 33 is arranged on the wall board 32 and connected with a hook of a steel angle pulling plate bend angle 71; the side groove 34 is used for placing the side buffering sealing joint strip 4; the side hole 35 is inserted with the aluminium alloy bracket 5; and the rectangle center hole 36 can be inserted with the steel angle plate 6 which is riveted with the wall board 32 after punching through with the connection angle of 90 degrees. The fixed connection structure has the advantages of being capable of bearing the impact effect of pulsating wind loading generated by high speed train, and being capable ofstably bearing the load of air mechanics for a long time.

Description

technical field [0001] The invention belongs to the field of railway components, and relates to a unit plate structure of a sound barrier, in particular to a fixed connection structure for a transparent unit plate of a sound barrier of a high-speed railway. Background technique [0002] The technical level of high-speed railways has been quite developed around the world, and the running speed of its EMUs is in the range of 230-400km / h. It is necessary to control the pollution caused by noise, and the development of sound barrier technology is also born. The structural form of the sound barrier adopts the metal plate type and the concrete integral type. The former is mostly used for viaducts, and the latter is mostly used for roadbeds. The shape and structure of the sound barrier are mostly upright and inverted L-shaped, and some locations have outward-inclined and inward-inclined types. The metal plug-in structure is to place the sound barrier unit board between the H-shap...

AI Technical Summary

Problems solved by technology

In the early stage, due to insufficient understanding of the pulsating force of the train, the strength of the unit plate itself and the insufficient connection strength between the sound barrier column and the bridge, etc., caused the resonance and fatigue damage of the unit plate

The static load and dynamic load of the sound barrier are not taken into account in the design of the viaduct bridge, resulting in restrictions on the structure, material and connection method of the sound barrier, resulting in insufficient strength
