STEEL MATERIAL FASTENING DEVICE, FASTENING MEMBER AND STEEL MATERIAL FASTENING METHOD
To simply and firmly fasten a steel material by fastening a nut from the outside, the steel material having such a characteristic that it is difficult to put a hand into the inside of a bent plate.SOLUTION PART: A steel material fastening device comprises: a square steel pipe 2 having a flat plate 2a with a first open hole, and a side plate 2b connected to the flat plate 2a; and an L-shaped bolt 8 inserted into the first open hole, and fastened to the steel material by a nut 19. The L-shaped bolt 8 comprises: a fastening shaft 8a, as a first shaft, having a screw thread engaged (screwed) to the nut 19; and a locking shaft 8b, as a second shaft, provided orthogonally to the fastening shaft 8a, and having an end part contacting with an inner surface of the side plate 2b in fastening.SELECTED DRAWING: Figure 1
【課題】屈曲した板の内側に手が入り難い鋼材を外側からのナット締め作業で簡単にかつ堅固に締結する。【解決部】鋼材締結装置は、第１の貫通孔を有する平板２ａと、平板２ａに接続される側板２ｂとを有する角形鋼管２と、第１の貫通孔に挿通され、ナット１９によって前記鋼材に締結されるＬ形ボルト８とを備える。Ｌ形ボルト８はナット１９に係合（螺合）するねじ山を有する第１の軸としての締め付け軸８ａと、この締め付け軸８ａに直交して設けられ、締結時に、側板２ｂの内面に当接する端部を有する第２の軸としての係止軸８ｂとを備える。【選択図】図１
