Description

{Bridge Inspection Road with Stress Distribution Structure}

The present invention relates to a bridge inspection road having a stress-dispersing connection structure, and more particularly, by dispersing stress in a connection portion between brackets extending and assembled at right angles to each other in a pier portion of a bridge for safety inspection and repair of the bridge. It relates to a bridge inspection road having a stress dissipation connection structure capable of effectively preventing structural bending of a scaffold by bridge inspection.

In general, various types of bridges are installed on destroyers that cross rivers or seas, including highways and national roads. For these bridges, a bridge inspection facility is installed that can always inspect the main structures without restriction of traffic flow, taking into account various conditions such as the temporary location and structural type, intersection conditions, and sub-support conditions.

This bridge inspection facility is a structure installed to provide efficiency for bridge management, such as checking and inspecting the functional state, age, and defects of each part of the bridge structure, and maintenance. It is mainly installed on the lower side, that is, on the upper side of the pier supporting the bridge, and consists of a bridge inspection path for workers to move and an access staircase including a ladder for accessing the bridge inspection path.

Here, looking at the structure of the bridge inspection path, a pier bracket fixed to the wall of the pier, a scaffold bracket having one end fixedly connected to the lower side of the pier bracket, guide posts and handrails installed along the edge of the other end of the scaffold bracket, It is composed of a scaffold panel that is continuously installed on the upper surface of the scaffold bracket so that the operator can walk.

As a prior art disclosed in relation to the bridge inspection path as described above, Korean Patent Registration No. 1911043 (2018.10.17.) discloses a bracket part mounted on a pier; a support part connected to the bracket part and protruding from the pier in a horizontal direction; a post connected to the support part and protruding vertically from the longitudinal end of the support part; a footrest portion disposed on the support portion while being connected to the support portion or the bracket portion; and a plurality of cross bars provided on the posts, wherein the bracket part includes: a base panel in contact with one surface of the pier and coupled thereto; an insertion panel protruding from the other surface of the base panel and having a space therein; and a reinforcing panel inserted into a space formed in the insertion panel; as it is configured, it provides convenience of installation work, and an inspection table for a bridge that can reduce overall manufacturing cost or installation cost is known.

However, in the prior art described above, since the coupling connection is simply assembled with a lock bolt between the bracket mounted on the pier and the supporting part for supporting the scaffold, shear force is concentrated and directly applied to the bolt whenever a continuous load is applied, making the binding site weak and the structure There was a problem that its stability was not guaranteed.
