PURPOSE: A prefabricated expansion sidewalk for a slope is provided to improve the safety of pedestrians by minimizing the shape change of the sidewalk. CONSTITUTION: A prefabricated expansion sidewalk for a slope comprises vertical frames(800), base brackets(100), multiple square steel members(200), coupling bodies(300), flooring members(400), and a safety fence(500). The base brackets are installed in the vertical frames. The square steel members are installed on the top of the base brackets. The coupling bodies couple the square steel members to the base brackets and are installed in the base brackets so that the square steel members can be expanded depending on a temperature change. The flooring members are installed on the top of the square steel members. The safety fence is installed in the upper flanges of the base bracket. |
