PROBLEM TO BE SOLVED: To provide an effective auxiliary tool for fixing a metal fittings such as a supporting rod for suspending an air-conditioning duct and a ceiling material, etc., from H-steel. SOLUTION: This auxiliary tool, by viewing the H-steel 1 from an end face side which is made for the suspending metal fittings having bolts in the vicinity of a top part, is made of (a) a channel-shaped metal member 3 which is a belt-shaped metal plate of a prescribed width, running along the whole horizontal lower surface of a lower flange 2 of the H-steel 1, with one end extended and the other end bent into an channel shape along a flange surface, and with a bolt insertion hole 8 for the suspending metal fittings provided in the extended part adjacently to an end edge of the lower flange 2 of the H-steel 1, (b) a metal flat plate 4 which is provided with a bolt insertion hole 8 for the suspending metal fittings and is mounted on an upper surface of the lower flange 2 of the H-steel according to the length of the extended part of the channel-shaped member 3, and (c) the combination of metal liner 5 and spacer 6 burying a space on the extension of the lower flange 2 of the H-steel 1 surrounded by the channel-shaped member 3 and the flat plate 4. As a result, cost, of the equipment is reduced, a mounting work is simplified, and a construction period is shortened. |
