い。2. Description of the Related Art Conventionally, iron landscape materials used for guardrails, fences, handrails, etc. installed on streets and the like require members to be assembled locally, and bolts are used for fastening members to each other because of their simplicity.・ Nuts are often used.
For example, if another pipe-shaped member with a smaller diameter is inserted into the pipe-shaped member and fastened, the landscape side material emphasizes the appearance after screwing, so the nut side is inside the pipe. Make appropriate bolt holes in both pipes, overlap those bolt holes, insert bolts of appropriate diameter and length from the outer side of the outer pipe, and insert them in the inner side of the inner pipe. Screw the nut and tighten. Specifically, while holding the nut at the tip of the bolt protruding inward from the bolt hole opening on the inner surface of the inner pipe with one hand or a tool such as a hex wrench, rotate the bolt head with a tool such as a hex wrench. Screw. While screwing in this way,
The nut must be held with one hand or the nut will fall off. However, it is very poor in workability to tighten a bolt or the like with a tool with one hand while holding a nut with one hand inside the pipe and holding the nut with the other hand.

する問題があった。[0003] Therefore, in order to enable fastening without using a nut, a female screw is formed in advance on the inner pipe instead of a bolt hole, and in the field, the bolt can be fastened simply by screwing it into the female screw and tightening. A method of greatly improving workability has been adopted. However, landscape materials are always used in an environment that is exposed to the wind and rain. Therefore, if they are used in a state where they are simply threaded, corrosion progresses therefrom, which not only impairs aesthetic appearance but also shortens the life. Therefore, in the case of this method, it is necessary to thread the pipe, apply plating by doweling or the like, and further remove an extra plating layer adhered to the threaded portion after plating. Had the problem of rising.

Devices and the like are collectively referred to as "fastened materials".

いことも考えられる。As means for solving the above-mentioned problem of workability when fastening a material to be fastened using bolts and nuts, for example, Japanese Unexamined Patent Application Publication No. 10-78018 discloses a technique called “a nut holding portion for fitting a nut. By using a cap for preventing dropping that has a bolt hole insertion part integrally, fitting and fixing a nut to the nut holding part, by inserting the opposite bolt hole insertion part into the inner peripheral surface of the bolt hole, The nut is held and fixed concentrically to the opening of the bolt hole via the cap for preventing the nut from falling off, so that the bolt and the nut can be screwed together without supporting the nut with one hand. " . However, according to the present invention, the above operation and effect can be obtained when relatively small bolts and nuts are used because they are only held and fixed by the frictional force between the cap for preventing falling off and the nut or the bolt hole, When using relatively large bolts and nuts, such as those used for fastening landscape materials, when holding and fixing the cap for preventing falling off in the opening of the bolt hole and inserting the bolt into the bolt hole and screwing it with the nut It is conceivable that the nut or the cap for preventing the cap is accidentally pushed strongly by the bolt, and in this case, there is a high possibility that the nut is detached from the cap for the cap or the cap for the cap is dropped from the bolt hole. Further, even if the bolt and the nut are screwed well, it is conceivable that a large torque may cause the nut to rotate together with the cap for preventing falling off when the bolt is tightened, so that a sufficient fastening force may not be obtained.

性が高い。On the contrary, as a method of holding and fixing a bolt to a material to be fastened, Japanese Patent Application Laid-Open No. Hei 8-27063
Japanese Patent Application Publication No. 2 (1994) discloses a method of mounting a vehicle underfloor part using a temporary holding clip used for mounting a underfloor mounting part such as a heat insulator that is mounted below a floor panel of a vehicle. The provisional holding clip provided with the cylindrical portion and the temporary fixing protrusion protruding outward from the outside of the cylindrical portion is attached to the outer periphery of the bolt of the heat insulator, and the bolt and the temporary holding clip are After inserting the temporary fixing protrusion into the bolt insertion hole of the floor panel from below the floor while elastically deforming it in the direction to reduce the outer diameter, it is locked on the upper side of the floor panel. And finally, the nut is fastened from the upper side of the floor panel to the bolt until the cylinder of the temporary holding clip is crushed. " According to the present invention, since the bolt is held in a state of protruding above the floor panel, it is easy to screw the nut with the bolt, and the possibility of the bolt falling off is reduced. In such a case, there is a high possibility that the bolt is rotated and sufficient fastening force cannot be obtained.

ため、より強い締結力が得られる。With the nut N fitted in the recess 3 of the nut holder 1, the engaging arm 6 is connected to the nut fastening surface 1 of the workpiece Wa.
When the engaging arm 6 is pushed into the engaging arm insertion hole 9 from the side 6, the engaging claw 7 at the tip of the engaging arm 6 projects outward, so that the engaging arm 6 is elastically bent to reduce the diameter, and the engaging claw is engaged. After passing through the arm insertion hole 9, the engaging arm 6 elastically returns to its original state after the passage, the locking claw 7 is engaged with the bottom surface of the recess 11, and the whole nut holder 1 is prevented from coming off. At the same time, the nut N is fitted into the nut rotation preventing portion 17 to prevent the bolt B from being screwed and screwed into the nut N and prevented from rotating. Also, nut holder 1
Since the bolt insertion hole 4 is formed at the bottom of the concave portion 3, the tip of the bolt B can be freely protruded from the bolt insertion hole 4 when the bolt B is tightened. It will not be pushed and fall off. Further, on the joint surface 10 side of the workpiece Wa, the tip end of the engaging arm 6 and the locking claw 7 are located outside the joint surface 10 (the workpiece Wb side).
Is formed so as not to protrude, the tip of the engaging arm 6 and the portion of the locking claw 7 are pinched between the workpieces Wa and Wb when the bolt B is tightened. Therefore, a stronger fastening force can be obtained.

止めされ連れ回りを防止できる。If the bolt B and the nut N are relatively small and the torque when the bolt N is tightened is not so large, the nut holding member 1 can be provided without providing the nut rotation stopper 17 on the workpiece Wa. Since the recess 3 is formed substantially similar to the nut N, the engaging arm 6 is formed wide, for example, so as not to be greatly deformed by the torque at the time of bolt tightening. Everything is stopped, and it is possible to prevent entrainment.

When the nut N is set in the concave portion 3, the nut N can play a little after the nut N is mounted on the concave portion 3. Therefore, even if the bolt B does not enter the bolt hole 8 accurately and straightly, it can be easily screwed with the nut N. It is preferable because the property is improved. Further, it is preferable that the inner size of the nut rotation preventing portion 17 is set slightly larger than the outer size of the nut N so that the nut N can be easily fitted and for the same reason as described above.

It is preferred. Further, the locking claws 7 may be formed inward instead of outward. In this case, by forming the locking arm insertion hole 9 apart from the bolt hole 8, the locking claw 7 is formed between the opening of the locking arm insertion hole 8 and the bolt hole 8 opening on the joint surface 10. And the nut holder 1 is locked.
