Problems solved by technology

The third option is to add columns in the middle span of the bridge, which has a better vibration reduction effect on the middle span of the main beam of the bridge, and a relatively large vibration reduction range for the middle span of the bridge deck, but the more columns are added, the track foundation The greater the degree of increase in vibration caused by transmission, the overall vibration reduction effect does not change much, and it is difficult to add columns in the middle span of the flyover, and the scheme of adding columns is limited by the use

Embodiment Construction

[0029] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments, so that those skilled in the art can better understand the present invention and implement it, but the examples given are not intended to limit the present invention.

[0030] Such as figure 1 , figure 2 and image 3 As shown, the high-speed rail pedestrian bridge vibration reduction ceiling device of the present invention includes 16 corbels 1, 8 dampers 2, 8 springs 3 and a ceiling 6. Each corbel 1 is respectively symmetrically welded to the inner surface of the flyover plank 4 and the flyover structural secondary beam 5 by double-sided fillet welds. The upper ends of the eight dampers 2 are suspended on one corbel 1 respectively. The lower ends of the eight dampers 2 are all connected to the suspended ceiling 6 . The natural frequency of the subsystem composed of the ceiling 6, the spring 3 and the damper 2 maintains a certain frequency d...

Abstract

The invention discloses a high-speed rail pedestrian overbridge vibration reduction suspended ceiling device and a processing method thereof. The device comprises a suspended ceiling, a plurality of brackets, a plurality of springs and a plurality of dampers, wherein each bracket is connected to the inner side face of an overbridge floor board and the inner side face of an overbridge structure secondary beam respectively, the upper end of each spring and the upper end of each damper are connected to each bracket respectively, and the lower end of each spring and the lower end of each damper are connected to the suspended ceiling. The high-speed rail pedestrian overbridge vibration reduction suspended ceiling device and the processing method thereof can resolve the problem of high-speed rail pedestrian overbridge vibration caused by train wind, have the obvious vibration reduction effect, are not restrained by the span of a high-speed rail pedestrian overbridge, and achieve flexible arrangement.

Description

technical field [0001] The invention relates to a vibration damping device on a high-speed railway pedestrian bridge and a processing method thereof, in particular to a vibration-damping ceiling device and a processing method of a high-speed railway pedestrian bridge that needs vibration reduction treatment due to the vibration of the bridge caused by train wind. Background technique [0002] The high-speed railway pedestrian bridge includes several flyover planks spliced ​​with each other arranged horizontally, each flyover plank lower surface is provided with flyover structural secondary beams, and the four flyover structural secondary beams on the lower surface of each flyover plank form a rectangular frame beam. A plurality of flyover purlins are arranged at intervals on the lower surface of the flyover plank located in the rectangular frame girder. The high-speed railway pedestrian bridge needs vibration reduction treatment because the train wind when the high-speed tra...
