STRAP BOLT WITH SPRING
PROBLEM TO BE SOLVED: To provide a strap bolt with a spring that enhances workability by preventing co-rotation of a first connection bolt for certain when tightening with a nut.SOLUTION: A first connection bolt support body 14, into which a first connection bolt 11 fixed on a girder 2 is inserted, is disposed on a base part side of a blade part 13, while a second connection bolt hole, into which a second connection bolt 15 fixed on a beam 3 is inserted, is disposed on a tip part side of the blade part 13. A spring 12 is disposed between a head part of the first connection bolt 11 and the first connection bolt support body 14, and a pair of erected pieces are erected on both sides of the blade part 13 to prevent rotation of the head part of the first connection bolt 11.SELECTED DRAWING: Figure 1
【課題】ナットによる緊結時の第１連結ボルトの供回りを確実に防止して施工性を向上させることができるスプリング付き羽子板ボルトを提供すること。【解決手段】羽根部１３の基部側に桁２に固定される第１連結ボルト１１が挿入される第１連結ボルト支持体１４を設ける一方、羽根部１３の先端部側に梁３に固定される第２連結ボルト１５が挿入される第２連結ボルト孔が設けられ、第１連結ボルト１１の頭部と第１連結ボルト支持体１４との間にはスプリング１２を設ける一方、羽根部１３の両側には、第１連結ボルト１１の頭部の回転を防止するよう起立した一対の起立片部を設けた。【選択図】図１
