Description

Anti-unlocking and Vibration Absorbing System of Bridge Inspection Path}

The present invention relates to a device for preventing loosening of a bridge inspection path and a vibration absorbing device, and more particularly, to absorb or minimize the amount of vibration and impact generated from the scaffolding panel when the worker moves, and the amount of vibration and impact generated from vehicles moving through the bridge. By absorbing or minimizing, it is possible to prevent loosening of the bolting fixing part in the bridge inspection path including the scaffolding panel, and accordingly, the loosening prevention and vibration absorbing device of the bridge inspection path that can prevent safety accidents in the bridge inspection path in advance. It is about.

In general, various types of bridges are installed on highways, national highways, and roads that cross rivers or seas. In addition, in such a bridge, it must be possible to inspect the main structure at all times without restricting the traffic flow in consideration of all conditions such as temporary location, crossing condition, structure type, bridge width, and lower support condition.

Accordingly, the bridge is equipped with facilities such as access, inspection, and lighting to check or inspect the functional status, deterioration and defects of each part of the bridge structure, as well as to efficiently manage maintenance, etc. Is being installed.

In particular, the bridge inspection facility is mainly installed at the lower part of the bridge, that is, on the upper side of the pier supporting the bridge so that it does not interfere with the flow of traffic. It is composed of entrance stairs including ladders, etc.

These bridge inspection paths include a pier bracket that has a certain length and is fixed to the wall of the pier, a scaffold support bracket with one end vertically fixed to the lower side of the pier bracket, and a scaffold support bracket that is vertically connected to the other end of the scaffold support bracket.
