FILLED-SPANDREL TYPE CONCRETE ARCH BRIDGE

摘要

PURPOSE:To reduce rigidity of respective parts, to make intervals between supports large and operation easy by laminating light weight material as filler for an arch bridge provided with arches between plural numbers of support and filled with filler for side walls forming thereof. CONSTITUTION:An arch 5 is extended between supports 1, 1 supported with lower structures 3, and disc bodies 11 made of foamed styrene are laminated and filled between side walls 7, 9 of the arch 5. Moreover, as filler is used that laminated with bar bodies or disc bodies made of formed styrene, or that laminated with pipes made of steel or resin, or disc bodies made of plastics and formed in honeycomb structure. Thereby, rigidity required for respective parts can be reduced while operation can be made easy.
