{Railing brace for inspection railing of angle-adjusted bridges}

The present invention relates to a balustrade post for an inspection handrail of a bridge in which the angle of the guardrail constituting the inspection handrail of the bridge can be adjusted according to the installation conditions of the pier, and more particularly, the Even when the shape and bending section are in the form of an inclined section rather than a right-angle section, the gear-type inner and outer rotating bodies are rotated accordingly and the horizontal handrail supports adjacent to both sides are accurately connected and installed at the corresponding inclination angle without any difficulty. It is related to the balustrade post for the inspection handrail of the bridge that can be adjusted to the angle.

In general, various types of bridges are installed on highways, national roads, or roads crossing rivers or seas. These bridges are equipped with facilities such as access, inspection, lighting, and ventilation so that the main structures can be inspected at all times without traffic restrictions in consideration of various conditions such as temporary location, intersection conditions, structural types, cross-section bridges, bridge widths, and lower support conditions. A bridge safety inspection facility has been installed to improve the efficiency of management, such as checking and inspecting the functional state and aging defects of each part of the structure, and maintenance.
