摘要
The present invention relates to a passage installed outside the pier of the bridge for the maintenance and inspection of the bridge state; The purpose is standardized, high productivity, low specific gravity, easy handling and installation, beautiful appearance, and permanent coloring at the time of production. It is easy to be absorbed, has excellent absorption and alleviating effects in shaking, and provides a plastic integrated bridge maintenance check passage having a property of excellent corrosion resistance and electrical insulation as a plastic with reinforcing material.;The present invention for achieving the above object is installed in the outer pier of the bridge in the passage for maintaining and checking the bridge state, one side has a 'c' shaped cross section having a plurality of bolt holes (2) for fastening to the wall surface A fixing unit 13 is formed, a supporting unit 12 formed perpendicularly to the lower fixing unit 13, and having a reinforcing structure at the end of the supporting unit 12 and bent upwards to form a plurality of penetrating circular shapes. A handrail 11 having a hole is mounted on the handrail post 10 formed of an integral type, a handrail bar 14 inserted into and coupled to a plurality of circular holes of the handrail 11, and an upper portion of the base 12. A plurality of standardized plates that can be stepped on by the inspector for inspection and are positioned at right angles to the support plate 15 and formed so that the inspector can move up and down to the maintenance and inspection passage 18 on the bridge. By combining the length of the dog It is a plastic integrated bridge maintenance passage consisting of a possible access ladder 16 and the entrance safety net 17 is installed to surround the access ladder 16 in a circular shape.;In addition, the handrail post (10), the support plate (15), the access ladder (16) and the access safety net (17) are manufactured by press-molding method of plastic with a high-strength light metal reinforcement (18) in the inner center. After fastening to (4), the bolt (4) was finished with silicon to consider the safety of passengers.
