Abstract

The invention discloses an auxiliary adjusting device for bridge crossing steel plates. The auxiliary adjusting device comprises rails and jacking devices mounted on the rails, wherein the length directions of the rails are vertical to the advancing direction of a beam, and the rails are located below the bridge crossing steel plates; and the jacking devices comprise pulleys, jack jacking platforms and jacks, the pulleys are mounted on the rails, the jack jacking platforms are located above the pulleys, the jacks are located above the jack jacking platforms, and after the bridge crossing steelplates are jacked upwards by virtue of the tops of the jacks, the movements of the bridge crossing steel plates in the width direction of a bridge are adjusted by virtue of the movements of the pulleys. The crossing of various types of vehicles can be facilitated by virtue of the steel plates, so that the construction efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of bridge construction, in particular to an auxiliary adjustment device for bridge cross-span steel plates. Background technique [0002] During the construction of expressway bridges, after the installation of the bridge T-beams with prefabricated hoisting beam structures, subsequent bridge deck construction is required. Between every two spans of T-beams, due to the continuous section or expansion joint on the top of the pier in the structural design, temporary cross-span steel plates need to be placed when various construction vehicles pass. Since the wheelbase of each vehicle is different, it is necessary to adjust the position of the cross-span steel plate at any time to accommodate the passage of vehicles. However, cross-span steel plates are generally cumbersome, requiring mechanical or multiple manual cooperation when moving, and each operation is very troublesome. After the vehicle hits the span s...
