PURPOSE:To realize easy fixing work in a short time and obtain the same durability as that of a fixing tool by the use of a nut by easily disposing a nutlike member in a desired position of a long bolt in a short time so as to apply the nutlike member. CONSTITUTION:There are provided with a tapered nut 5 having a nutlike profile with a female screw 51 and a taper 52, which is contiguous to the female screw 51 and tapered gradually, contained therein, and a split nut 6 housed inside the nut 5 and having a profile corresponding to the inner wall surface of the nut 5, with a screwlike unevenness 62 disposed on the inner wall. Furthermore, an elastic body 7 is contained under the split nut 6 inside the tapered nut 5, a head portion 81 having a nutlike profile is disposed, and a male screw portion 83 is screwed with the female screw 51 of the tapered nut 5. Moreover, a nutlike member is constituted of a through bolt 8 where a through hole 82 having a diameter slightly larger than an outer diameter of a bolt 2 to be tightened is bored. A suspending metal material 3 having a hole and a bending projection 32 formed in an upward bending portion is combined with the nutlike member, thus obtaining a ceiling frame member supporting tool. |
