Claims

[Claims for Utility Model Registration] (1) An upper H-shaped steel with flanges placed up and down is placed so as to intersect with a lower H-shaped steel placed with its flanges up and down, and the lower H-shaped steel A connection structure for H-beams, characterized in that an upper flange of steel and a lower flange of the upper H-beam are held together by fixing fittings, and the upper H-beam is connected to the lower H-beam. (2) The fixing fittings include two upper fixing members that abut on the upper surfaces of both sides of the lower flange of the upper H-shaped steel across the web, and protrude from both sides of the upper flange of the lower H-shaped steel in the width direction; two lower fixing members that respectively abut the lower surfaces of the upper flange of the lower H-shaped steel on both sides sandwiching the web and protrude from both sides of the lower flange of the upper H-shaped steel in the width direction; and the upper fixing member. and a screwing member that screws both ends of the lower fixing member to both ends of the lower fixing member.
Connection structure of the H-shaped steel described. (3) An upper spacer is arranged between the upper fixing member and the upper surface of the upper flange of the lower H-beam, and between the lower fixing member and the lower surface of the lower flange of the upper H-beam, 2. Lower spacers are respectively arranged, and the upper fixing member is screwed to the lower fixing member via the upper spacer and the lower spacer by a screwing member. 2. Connection structure of H-beam steel according to 2.
