ARCHED WIDER WIDTH WALE AND WALE STRUCTURE BY USING OF IT

摘要

Provided is an arched wide wale comprising: a body unit including an upper flange coming in contact with a retaining wall, a web installed to the upper flange, a lower flange installed to the web, and a front plate installed to both ends thereof; an arch reinforcement unit installed in the lengthwise direction of the body unit to disperse and support load transmitted from the retaining wall; and an end step unit installed on both ends of the body unit to connect the arched wide wales contiguous with each other. The arch reinforcement unit is installed on the entire lengthwise part of the main body to deliver the load transmitted from the retaining wall to both ends of the body unit and has the upper protruding part welded to the upper flange. Both ends of the arch reinforcement unit are welded to both ends of the lower flange, and one side of the arch reinforcement unit in the longitudinal direction is welded to the web. The width of the upper flange is narrower than that of the lower flange, and the width of the arch reinforcement is determined in order for the width of the central part coming in contact with the upper flange to be narrower than the width between both ends coming into contact with the lower flange.
