Steel structure of bridge structure preventing vibration

摘要

The present invention relates to a bridge made of steel structure and more particularly to a bridge using a steel structure 60 in which steel boxes 10 are connected to each other and supported by supports 50 of piers 40, , An insertion hole (12) formed on one side surface of the base plate (1) so as to penetrate to the inside and the outside; An air injection member 20 which is inserted into the through hole 12 and installed in the steel box 10 and which absorbs vibration of the steel box 10 by filling air with the injection hole 22; A fixing bolt 40 inserted in a screw hole 32 is fastened to a plurality of fastening holes 14 formed in an outer circumferential surface of the insertion hole 12 of the steel box 10, The steel structure of the steel structure of the bridges preventing the vibration, which is constructed of the shielding plate 30 for blocking the vibration of the steel structure, the vibration of the steel structure of the bridge is absorbed by the air injection member, Is prevented from being damaged and broken.
