Articulated concrete block and arch bridge for arch bridge structure

摘要

PROBLEM TO BE SOLVED: To provide an easy-to-manufacture, easy-to-convey and versatile connected concrete block body for an arch bridge structure, which has a high degree of freedom of design, which hardly causes fracture during lifting work, and which prevents blocks at both ends from getting away from an arc line of an arch.SOLUTION: In a connected concrete block body for an arch bridge structure, a group, in which a plurality of arch-stone blocks are integrated together by being connected together by an embedded connecting member, serves as a block group, and the block groups are connected together to wholly serve as a series of integrated connected concrete block body. When the connected concrete block body is lifted to form an arc shape, it can be formed into an arch bridge.SELECTED DRAWING: Figure 2
