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...
