Description

[0001]
[Industrial application fields]
The present invention relates to a metal fastening material used for fastening a plurality of articles to each other.
[0002]
[Prior art]
To fasten the articles together, for example, as described in Japanese Patent Application Laid-Open No. 2001-9751, a wire is applied to the article, and the ends of the wire are turned forward for about one rotation, twisted with a hand to form a ring shape, There is a means in which a hook provided on a rotor of a tool is hooked on the front side of a ring-shaped wire, and the wire is twisted by rotating the rotor.
[0003]
[Problems to be solved by the invention]
In the conventional example, since the hook is hooked on the ring-shaped wire during the twisting operation by the tool (rotor), the wire may be wound around the hook. For this reason, the twisting operation must be moderated. In addition, after the twisting operation, the hook must be artificially removed from the wire.
[0004]
Since the wire has to be made into a ring shape once from the beginning, the work is complicated.
[0005]
The present invention pays attention to the disadvantages of such a conventional example, and it is possible to fasten articles by twisting using a tool having a rotor with a hook, and the hook is automatically detached from the fastening material after fastening. The invention has been invented for the purpose of providing a fastening material suitable for handling.
[0006]
[Means for Solving the Problems]
It is set as the structure which provided the ring piece which latches the hook with which the rotor of the rotary tool was equipped at both ends of the linear main body wound around articles | goods helically.
[0007]
【Example】
FIG. 1 is a perspective view, FIG. 2 is a sectional view showing a use state, and FIG. 3 is an explanatory view.
[0008]
In the figure, A is a fastening material according to the present invention, and the fastening material A is formed by bending a metal (stainless steel in the embodiment) wire, and arc-shaped portions 1b and 1b are opposed to both ends of the central upper portion 1a. In addition, the ring pieces 2 and 2 are spirally provided at both ends of the substantially U-shaped linear main body 1 (the free ends of the arcuate portions 1b and 1b) as a whole. is there.
[0009]
In an old tunnel, an accident of falling a concrete piece on the wall surface is likely to occur. To prevent the accident, a support rod 11 made of H-shaped steel is provided along the wall surface of the tunnel. A means for stretching the wire mesh 12 between the eleventh and eleventh is adopted. In FIG. 2, the case where the fastening material A is used in order to fasten this support rod 11 and the wire mesh 12 is shown.
[0010]
That is, a wire mesh 12 is arranged inside the outer piece 11a of the support rod 11, and the linear main body 1 of the fastening material A is passed through the wire mesh 12 through a through-hole 13 formed at an appropriate position of the outer piece 11a to rotate the tool. When hooks 15, 15 provided by bifurcating the tip side of the child 14 are engaged with the ring pieces 2, 2 and the rotor 14 is rotated, the arcuate portions 1 b, 1 b of the linear main body 1 are rotated. Are twisted with each other, and the wire mesh 12 (the end thereof) is fastened and fixed to the support rod 11.
[0011]
During the rotation operation of the rotor 14, the ring piece 2 is formed in a spirally wound ring shape, so that the spiral shape is scattered (sometimes cut by the load of the rotational force of the rotor 14 to the hook 15). The ring piece 2, that is, the fastening material A, is in a state where both the articles 11 and 12 are fastened and is automatically detached from the hook 15.
[0012]
Note that the rotor 14 of the embodiment is provided with a pair of hooks 15, 15, but a tool with a rotor used so that the ring pieces 2, 2 are assembled to each other in a single hook. Of course, may be used.
[0013]
The fastening material A does not have to be limited to the shape of the embodiment, but when used for fastening the support rod 11 and the wire mesh 12 shown in FIG. In addition, after insertion, the inner edge of the straight portion 1a of the main body 1 contacts the wire mesh 12, so that the twisting operation can be performed without difficulty, and when fastening at the ceiling of the tunnel, It is preferable because it can be suspended from the wire mesh 12 in a stable state due to the presence of the shape portion 1a (FIG. 2).
[0014]
Although it is the helical pitch which comprises the ring piece 2, although it is so favorable that a pitch is about 1 to 2 pitches and it is small, it should be decided by the raw material of the fastening material A.
[0015]
【The invention's effect】
Since this invention is a structure as above-mentioned, a product with favorable workability | operativity can be provided as a fastening material which fastens articles | goods using a lower transfer tool.
