Summary:To provide a corner structure for concrete structures capable of disposing multiple composite reinforcements also at a corner part.SOLUTION: In the corner structure of a bridge pier 1, multiple spiral columns 2, 2A composed of an H-shaped steel 3 and a rebar assembly 4 enclosing the same are disposed. The corner structure includes: an H-shaped steel 3A disposed at a joint of a corner part 10; spiral columns 2, 2 disposed on both sides having the H-shaped steel 3A therebetween; and a corner part rebar assembly 5 that encloses the H-shaped steel 3A and is connected to the H-shaped steel 3, 3 of the spiral columns 2, 2.SELECTED DRAWING: Figure 1 【課題】隅角部においても複数の複合補強材を配置することが可能となるコンクリート構造物の隅角部構造を提供する。【解決手段】Ｈ形鋼３とそれを包囲する鉄筋組立体４とによって形成されたスパイラルカラム２，２Ａが配置された橋脚１の隅角部構造である。そして、隅角部１０の節点に配置されたＨ形鋼３Ａと、Ｈ形鋼３Ａを挟んだ両側に配置されたスパイラルカラム２，２と、Ｈ形鋼３Ａを包囲しつつスパイラルカラム２，２のＨ形鋼３，３に接続された隅角部鉄筋組立体５とを備えている。【選択図】図１
