Abstract

PURPOSE:To attempt fixing of a bolt into a fixing hole by an elastic cylindrical body wherein a bolt insertion hole is formed in the center area, and an inclined surface is formed on the lower end and an elastic column body wherein a protrusion for preventing dragged turn is formed on the outer peripheral surface, an inclined surface is formed on the upper end and a nut is molded into the center part. CONSTITUTION:A fixing hole 15 is formed on a fixed surface 14 by using a diamond cutter, etc., and a cylindrical body 2 and a column body 5 are integrally inserted into this hole 15, and a signboard attaching angle 16 is placed thereon, and a tightly fixing bolt 11 is inserted into the cylindrical body 2 from the angle 16 after being braced with a washer 13, and a screw part 12 is screwed into a threaded hole 7a of a nut 7 of the column body 5 and then fastened. Thereby, the column body 5 is raised in the direction of an arrow mark A since its dragged turn is prevented in the hole 15 by a protrusion on the front surface. As a result, the cylindrical body 2 as an elastic body is made eccentric by action of the inclined surfaces 3, 6 and expanded outward by receiving pressure from above and below and then brought in pressure contact with the hole 15 by this action. In this case, the column body 5 is also expanded, and the angle 16 is fixed by the pressure contact action.

【発明が解決しようとする課題】しかし、上記公知例に
おいては、次のような欠点がある。However, the above-mentioned known examples have the following drawbacks.

【０００５】ａ．現場でアンカーボルトを埋め込む方法
の場合、工事が大掛かりとなり、作業に手間と時間及び
経費がかかる。A. The method of embedding the anchor bolts on site requires a large amount of work, which requires labor, time, and cost.

で供廻りをしてしまい、いくらボルト側を廻しても締め
付けができないことが多い。B. In the case of a combination of a nut that causes misalignment and an anchor bolt, the work is simple, but this fixing hole needs to be slightly larger than the nut because it is necessary to first insert the nut into the fixing hole. For this reason, even when trying to tighten the bolt, the nut side circulates within the fixing hole, and it is often impossible to tighten the bolt side no matter how many times it is turned.

If the paved road surface repeatedly expands and contracts due to a change in temperature after the structure is attached, the frictional force between the nut and the fixing hole may be attenuated and slip out.

いという欠点がある。D. Since the nut is made of metal and its surface is smooth, even if misalignment occurs due to bolt tightening, the friction surface with the fixing hole is only one point (a line parallel to the core), not the circumferential surface. Therefore, fixed force (friction force)
Has a disadvantage that it cannot be used for those requiring small strength.

を最小限に抑えて抜け出るのを防止する。In the fixing device, a fixing hole (stupid hole) is formed in the fixing place by using a diamond cutter or the like, the cylindrical body and the cylindrical body are inserted into the fixing hole, and the structure side, such as an angle, is inserted into the fixing surface. Place it, put a washer on it, pass the tightening bolt through, and screw the tip of this tightening bolt into the screw hole of the nut in the cylindrical body to tighten it. At this time, the columnar body does not idle around in the fixing hole due to the action of the anti-rotation projection formed on the outer peripheral surface of the columnar body. When the tightening bolts are tightened in this way, the cylindrical body rises due to the pitch of the screw, and in the course of this rising, the inclined surface acts to cause the cylindrical body to be misaligned (eccentric), and this cylindrical body is fixed in the fixing hole. Press the inner surface. Then, when the tightening further progresses, the cylindrical body has no escape place in the fixing hole, and eventually the compression force from above enlarges (the diameter increases), and the entire outer peripheral surface presses (contacts) with the entire fixing hole. At this time, the columnar body side also expands and press-contacts (contacts) with the fixing hole. Not only does this force not come out due to the frictional force due to this pressure contact, but even if the road surface repeatedly expands and contracts due to changes in temperature, it is absorbed by the elastic action of the cylinder and cylinder, and the damping of frictional force is minimized. Keep it at a low level to prevent it from coming out.
