COLUMN-BEAM JOINT STRUCTURE AND CONSTRUCTION METHOD FOR COLUMN-BEAM JOINT STRUCTURE

OKABE JUNJI

To provide a column-beam joint structure that easily joints a steel beam and a steel column by using a general member without performing special processing, and a construction method using the column-beam joint structure.SOLUTION: A column-beam joint structure 1 is the structure that joints a panel zone 22 jointed to a column part 21 formed by a rectangular steel tube and a steel beam 3 constituted to fix a tabular end plate 31 at a longitudinal edge of a long beam part 32 formed with shaped steel. The column-beam joint structure comprises a joint metal fixture 4 that is formed by fixing bolt heads 41a of first bolts 41 penetrating the panel zone 22 and the end plate 31 to joint them and one end part of second bolts 42 having longer bolt axes than the first bolts 41 in an axial direction onto the plate surface of a tabular fixed plate 43 in non-rotatable manner, and that is inserted to a hollow part S of the panel zone 22. The second bolts 42 protrude bolt axes 42a from positions avoiding the end plate 31 to outsides of the hollow part S, and screw first nuts 5 to the bolt axes 42a protruded from the panel zone 22.SELECTED DRAWING: Figure 2

【課題】特殊な加工を施さず、一般的な部材を使用して容易に鉄骨梁と鉄骨柱とを接合する柱梁接合構造及び柱梁接合構造を用いた施工方法を提供することを目的とする。【解決手段】柱梁接合構造１は、角形鋼管で形成された柱部２１に接合されたパネルゾーン２２と、形鋼で形成された長尺な梁部３２の長手方向の縁端に平板状のエンドプレート３１を固定してなる鉄骨梁３と、を接合する構造であって、パネルゾーン２２及びエンドプレート３１を貫通して接合する第１ボルト４１のボルト頭部４１ａ及び、当該第１ボルト４１よりもボルト軸が長い第２ボルト４２の軸方向の一端部を平板状の固定プレート４３の板面に回動不能に固定して形成され、パネルゾーン２２の中空部Ｓに挿入される接合金具４を備え、第２ボルト４２は、エンドプレート３１を避けた位置から中空部Ｓの外側へボルト軸４２ａを突出させるとともに、パネルゾーン２２から突出させた当該ボルト軸４２ａに第１ナット５を螺合される。【選択図】図２
