THERMAL PRESTRESSED STEEL BEAM WITH LAMINATED ECCENTRIC BRACKET

摘要

PURPOSE: A steel girder to which thermal prestressing is applied using a laminated eccentricity bracket is provided to solve e a structural problem of a connection unit and to be recycled by being laminated at a predetermined height. CONSTITUTION: A steel girder to which thermal prestressing is applied using a laminated eccentricity bracket comprises a girder main body(11), a laminated eccentricity bracket(12), and a prestressing steel plate(13). The laminated eccentricity bracket is installed at the lower part of the girder main body and comprises a structure in which a plurality of unit modules is laminated and is connected to each other. Both ends of the prestressing steel plate are fixed to the lower part of the laminated eccentricity bracket and apply thermal prestressing to the girder main body. The laminated eccentricity bracket comprises an upper unit module(121) and a lower unit module(123). A slip prevention plate is connected to the lower part of the upper unit module and controls the slip of the lower unit module.
