摘要
The subject innovation is installed on the external piers of the bridge towards a passage for the maintenance and inspection of the bridge condition; Object has a high productivity and standardized, and a specific gravity of the handling and installation easier and lighter, appearance is beautiful and, and the corrosion resistance and electrical insulating properties superior to plastic materials, coloring are possible in a separate painting and external maintenance costs are not needed at all, It is easy to manufacture by press forming, and to shake to provide a passage for a plastic one-piece bridge maintenance check having absorption and mitigation action is superior properties.; The invented for achieving the above object, according to the passage is provided in the pier outside of the bridge for maintenance and inspection of the bridge state, one side is shaped "c" having a plurality of bolt holes (2) for fastening to a wall having a cross-section the fixing portion 13 is formed, the fixing portion 13 and the receiving portion 12, which is vertically formed at the lower, had have a reinforcement structure at the end of the receiving portion 12 is bent upwardly on the circular to the plurality of through and a ledge 11 having a hole is made in one-piece railing post 10, a handrail railing bar (14) is coupled is inserted into a hole on a plurality of circular (11), so topped on top of the pedestal section 12 is normalized to be checker is located at right angles to the upper direction of the stepping can carry over to the base plate 15, base plate 15 in the inspection and testers are formed in the bridge superstructure to floating up and down in the maintenance and inspection passage 18 a number combining the pieces to a length adjustment Possible access ladder (16) and, holding a plastic one-piece bridge consisting out safety net 17 that is installed to surround the access ladder (16) in a circular passage for the check.; In addition, after the conclusion of the parts with a bolt (4) the end of the bolt 4 in a siliconized considered the passage's safety.
