COLUMN-BEAM JOINT STRUCTURE

To provide a column-beam joint structure capable of improving a joint strength between a column and a beam.SOLUTION: A car port includes a column 2A, a beam 3A, and a roof. The column 2A includes a cylindrical column body 20, and a reinforcing material 25 which reinforces the column body 20 and extends in a vertical direction. A joint body 11 is fixed to the column 2A to which the beam 3A is joined. In a hollow part 251 of the reinforcing material 25, a first backing piece part 141 along a first reinforcing side piece part 28 and a backing body 13 having a second backing piece part along a second reinforcing side piece part 29 are arranged. The first backing piece part 141 and the second backing piece part are joined to each other. The joint body 11 is fixed to the first backing piece part 141 while sandwiching the column body 20 and the first reinforcing side piece part 28 between the joint body and the first backing piece part 141. The second backing piece part is fixed to the second reinforcing side piece part 29.SELECTED DRAWING: Figure 3 【課題】支柱と梁の接合強度を向上できる柱梁接合構造を提供すること。【解決手段】カーポートは、支柱２Ａ、梁３Ａおよび屋根を備える。支柱２Ａは、筒状の支柱本体２０と、支柱本体２０を補強する上下方向に延びた補強材２５とを備える。支柱２Ａには梁３Ａが接合される接合体１１が固定される。補強材２５の中空部２５１には、第一補強側片部２８に沿った第一裏当片部１４１と、第二補強側片部２９に沿った第二裏当片部とを有した裏当体１３が配置される。第一裏当片部１４１および第二裏当片部は互いにつながれている。接合体１１は、第一裏当片部１４１との間に支柱本体２０および第一補強側片部２８を挟んで当該第一裏当片部１４１に固定される。第二裏当片部は、第二補強側片部２９に固定される。【選択図】図３
