PURPOSE: A flexible joining device for a bridge is provided to extend a life time with high intensity, to be easily maintained by simply adjusting the height, to enhance safety and reliability by suppressing the crack generation without vibration and noise, to smoothly discharge rain or impurities, to semi-permanently use a drainage hole, to prevent from being damaged even if a snowplow is used, to be rapidly repaired and to enhance waterproof property. CONSTITUTION: A flexible bridge joining devices(100) consists of; a space unit(140) formed between right and left structures(1); supporting units(110) integrated with each structure by inserting angles(111) into the corresponding faces of two structures and stuck to the angles by exposing the angles to be equalized with the side and the upper face and by combining frames(112) with the corresponding faces of the structures; a drainage unit(130) containing a cylindrical rain holder(131) in the space unit, an opening portion(133) in the upper side of the rain holder, a combining piece(132) horizontally placed in both sides of the opening portion, and holes(134) corresponding to screw holes(113) of the frames; and flexible joining units(120) containing main plates(121) combined with the rain holder, combining holes(122) having sills equalized with the screw holes of the supporting units and the holes of the drainage unit, on the main plate, combining bolts(123) connecting the combining holes and the holes of the drainage units, and height adjusting plates(125) adjusting the height of the main plates.
