Document Type and Number:
Japanese Patent JP2017031683
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a connection structure capable of preventing a precast member from being pushed up, even when flow-down water pressure acts on a joint part of the precast member.SOLUTION: A joint part end surface 2, which is installed to be positioned on a downstream side of a wear-resistant precast member 1 laid on an apron part, has an upper part 3 composed of a reversely-stepwise step part protruding in a flow-down direction. A joint part end surface 5 on an upstream side of a precast member 4 installed on the downstream side has a lower part 6 composed of a stepwise step part protruding in an upstream direction. Both the precast members 1 and 4 are connected together by vertically overlapping each other via the joint part end surfaces 2 and 5.SELECTED DRAWING: Figure 1
