LINING GIRDER, TEMPORARY STRUCTURE USING SAME, AND METHOD FOR CONSTRUCTING SAME

摘要

Provided is a lining girder, a temporary structure using same, and a method for constructing same. The lining girder of the present invention comprises: a pair of parallel steel plates including an upper flange, a web, and a lower flange; and a lining part including a pair of side plates arranged opposite one another and a flat plate, wherein the lining part is assembled to the pair of steel plates to constitute a girder structure having a downwardly opened cross-section. At the side plate, a ?-shaped steel beam is coupled to the top surface of the upper flange so as to expose a portion of the top surface of the upper flange on the pair of parallel steel plates. The flat plate is integrally connected between upper ends of the pair of side plates.
