REINFORCED CONCRETE COLUMN SWITCHING STRUCTURE
To improve workability when switching a reinforced concrete column into a square column and a small cross-section column on an upper side and a lower side with a predetermined upper and lower intermediate portion as a boundary.SOLUTION: Provided is a reinforced concrete column switching structure in which a reinforced concrete column 20 is switched to a rectangular column 20B with a square cross section and a small cross-section column 20C with a small cross section in which four corners of the square cross section are retired toward the center of the column on an upper side and a lower side with a predetermined upper and lower intermediate portion 20A as a boundary. In the column 20, as a main reinforcement 21 of the rectangular column 20B and the small cross-section column 20C, a through main reinforcement 21 is arranged across the rectangular column 20B and the small cross-section column 20C after making the main reinforcement arrangement in the rectangular column 20B and the main reinforcement arrangement in the small cross-section column 20C the same in plan view. Auxiliary reinforcements 24 are arranged at four corners of the rectangular column 20B to hold each corner of a tie bar 22, which is bent into a rectangular shape in plan view according to the cross-sectional shape of the rectangular column 20B while surrounding the through main reinforcement 21.SELECTED DRAWING: Figure 2
【課題】鉄筋コンクリート造の柱を、その所定の上下中間部を境にした上方側と下方側とで四角形柱と小断面柱とに切替える場合の施工性の向上を図れるようにする。【解決手段】鉄筋コンクリート造の柱２０が、その所定の上下中間部２０Ａを境にした上方側と下方側とで、断面四角形の四角形柱２０Ｂと、その断面四角形の四隅を柱中心側に引退させた形状の小断面を有する小断面柱２０Ｃとに切替えられる鉄筋コンクリート造の柱切替え構造において、柱２０には、四角形柱２０Ｂでの主筋配列と小断面柱２０Ｃでの主筋配列とを平面視で同じにした上で、四角形柱２０Ｂと小断面柱２０Ｃの主筋２１として、四角形柱２０Ｂと小断面柱２０Ｃとにわたる通し主筋２１が配筋され、四角形柱２０Ｂの四隅には、通し主筋２１を囲う状態で四角形柱２０Ｂの断面形状に応じた平面視四角形に曲げ形成される帯筋２２の各角部を保持する補助筋２４が配筋されている。【選択図】図２
