Moving Prevention Structure for Slab of Grand Bridge

摘要

PURPOSE: A slab moving prevention structure of a grand bridge is provided to increase the interval between main towers of a grand bridge by preventing a slab from being moved by wind. CONSTITUTION: A slab moving prevention structure of a grand bridge comprises a slab member(20), wind shield members(40), and a wind force supporting wire member. The slab member is supported with a cable member connected to a plurality of separated main towers. The wind shield members are arranged separately from each other on both sides of the slab member and moved along the width of the slab member by wind blown from the opposite side. The wind force supporting wire member connects the wind shield members to the slab member and pulls the slab member in the opposite direction to the wind direction by the movement of the wind shield members, thereby supporting the slab member.
