The utility model provides a modularized multi-pass device of a bridge frame for bridge frame construction. The multi-pass device is characterized in that the device comprises a flat plate, connecting ends and a connecting device, wherein the connecting ends are mounted on the side face of the flat plate through the connecting device. With the adoption of the device, when multiple bridge frames are laid on the same horizontal plane and a horizontal three-pass or a horizontal four-pass or even a horizontal multi-pass needs to be mounted, the horizontal passes can be still mounted on the same horizontal plane; not all the bridge frames need to be rolled and bent; a construction method is convenient and quick; the construction speed is increased; elbows are reduced; a cable is more convenient to lay; the construction cost is lowered; a space is saved; and the device is attractive and compact.
