Description

Unified plastic pathway for inspecting safety and maintenance of bridge with quality of electric resistance and rigidness and its manufacturing method}

The present invention relates to a passage for the maintenance and inspection of the bridge state and a method for manufacturing the same, which is installed outside the bridge pier of the bridge, and more particularly, the assembly and installation is possible, the safe passage of the inspector to maintain and inspect the bridge state The present invention relates to a passage for inspecting a plastic-integrated bridge for maintaining high strength, which is simple and economical, and a manufacturing method thereof.

At present, the inspection facilities that are assembled and installed at each site are constructed without any special standards, and thus are inadequate, such as low quality and inconsistent purposes. Normally, the bridge maintenance inspection facilities currently being constructed can be largely divided into inspection passages and access ladders.

In addition, the inspection facilities are mostly installed through the rivers and the sea, and the emphasis is placed on preventing material deformation and corrosion caused by salt and water.

For this reason, in the past, as a material for the bridge maintenance inspection passage, it has been used a lot of general steel which is low in price, easy to weld and bolt, and has excellent installation work in complex structures, but it is heavy and installs in the field. Due to this difficult, expensive installation cost and severe corrosion in the air, additional painting and repairing costs are added periodically, so durability and maintenance are becoming serious problems. In recent years, stainless steels having high efficiency such as high strength deterioration instead of steels, Materials such as aluminum alloys are mainly used.

However, the inspection passage made of the above materials is expensive, and is exposed to the risk of leakage or electric shock from facilities that use electricity such as lightning and high-speed railways that are increasing in use during rainy inspections. In addition, the fastening method also uses the bolt body and the welding, and the incidence of traffic accidents caused by the protruding bolts and the inconvenience of welding, and the number of components are large, resulting in material loss and post-maintenance in assembly and installation. There are many disadvantages.

The present invention is devised to solve such a conventional problem, it is standardized, high productivity, light weight, easy to handle and install, beautiful appearance, high strength reinforcement of the plastic with a corrosion-resistant, durable and electrical Excellent insulation and permanent coloration during product production, eliminating the need for separate painting and exterior repair costs, easy to manufacture by press molding method, and integrated plastic bridge with excellent absorption and relieving effect even during shaking An object of the present invention is to provide a maintenance inspection passage and a method of manufacturing the same.
