CONE MOUNTING METHOD OF TOP SIDE DECK

摘要

PURPOSE: An installation method of a cone structure in a top side deck is provided to weld a heavy cone structure to a top side deck using a stair tower without an additional scaffold. CONSTITUTION: An installation method of a cone structure in a top side deck is as follows. A top side deck (100) is built on the ground. An existing cone structure installed on a deck support unit (120) is removed. The top side deck is lifted up by installing a jacking column using the position where the existing cone structure is removed as a jacking point. A deck support device (200) is installed on the bottom surface of the top side deck, and a cone structure (110) is installed on a stair tower (600). The stair tower is moved to a position below the installation position of the cone structure. The cone structure is attached to the deck support unit.
