Title:
耐摩耗プレキャスト部材間の連結構造
Document Type and Number:
Japanese Patent JP6741846
Kind Code:
B2
Abstract:
To provide a connection structure which can prevent push-up of a precast member even when a water pressure in a downward flow direction acts on a joint part of the precast member.SOLUTION: A joint part end face 2 which is installed so as to be positioned on the downstream side of an abrasion-proof precast member 1 laid in the downward flow direction of a front apron part is composed of a reverse-stepped step part projecting whose an upper part 3 projects in a downward flow direction, a joint part end face 5 on the upstream side of a precast member 4 installed on the downstream side is composed of a stepped step part whose a lower part 6 projects to an upstream direction, and both of the precast members 1 and 4 are connected to each other by vertically overlapping on the joint part end faces 2 and 5. A joint part 34 parallel to the downward flow direction formed between the side faces 17 and 17 of the abrasion-proof precast members 1 and 1 installed vertical to the downward flow direction is formed so that a vertical cross section expanded from the upper part side to the depth part side has a trapezoidal shape, and the joint part 34 is filled with a joint member 35.SELECTED DRAWING: Figure 1
