JOINT STRUCTURE OF STEEL MEMBER AND JOINT METHOD OF STEEL MEMBER

To provide a joint structure of steel members and a joint method of steel members capable of joining steel members easily by a method without fire without welding the steel members with each other.SOLUTION: A joint structure 1 of steel members in which a steel beam (second steel member) 3 is joined to a steel pillar (first steel member) 2 includes a joint steel material 4 joined to the steel beam 3 and a joint screw 5 for joining the joint steel material 4 to the steel pillar 2. The joint screws 5 are inserted in first hole parts 411a, 421a, 432a formed in the joint steel material 4 and second hole parts 21a, 22a formed in the steel pillar 2. The first hole parts 411a, 421a, 432a are formed to have a larger inner diameter than the diameter of a screw part of the joint screw 5, and the second hole parts 21a, 22a are formed to have a smaller inner diameter than the diameter of the screw part of the joint screw 5. The joint screws 5 are screwed with the second hole parts 21a, 22a.SELECTED DRAWING: Figure 1 【課題】鋼製部材どうしを溶接することなく火無し工法で容易に接合することができる鋼製部材の接合構造および鋼製部材の接合方法を提供する。【解決手段】鋼製柱（第１鋼製部材）２に鋼製梁（第２鋼製部材）３を接合する鋼製部材の接合構造１において、鋼製梁３に接合された接合鋼材４と、接合鋼材４を鋼製柱２に接合する接合ネジ５と、を有し、接合ネジ５は、接合鋼材４に形成された第１孔部４１１ａ，４２１ａ，４３２ａおよび鋼製柱２に形成された第２孔部２１ａ，２２ａに挿通され、第１孔部４１１ａ，４２１ａ，４３２ａが接合ネジ５のネジ部の径よりも大きい内径に形成されて、第２孔部２１ａ，２２ａが接合ネジ５のネジ部の径よりも小さい内径に形成されていて、接合ネジ５が第２孔部２１ａ，２２ａに螺合している。【選択図】図１
