CORRUGATED STEEL WEB BOX GIRDER BRIDGE, AND CONTINUOUS SUPPORT STRUCTURE THEREOF

摘要

PURPOSE: A continuous support structure of a corrugated steel plate web prestressed concrete (PSC) box girder bridge and the corrugated steel plate PSC box girder bridge including the same are provided to reduce the thickness of a wall in a support structure and reduce a self-weight of the corrugated steel plate PSC box girder. CONSTITUTION: A continuous support structure of a corrugated steel plate web PSC box girder bridge with improved capability comprises as follows. A pair of corrugated steel plate webs (1) is individually continued in a longitudinal direction. A reinforced concrete support structure is formed between a pair of the corrugated steel plate webs. A connection plate (2) in which a penetration hole (20) is formed in a section in which a wall is formed is integrally included on the inner surface of the corrugated steel plate web. A plurality of the connection plates is installed with intervals in a longitudinal direction, and a penetrating reinforcing bar (3) is arranged on the penetration hole.
