Description

[Detailed Description of the Invention] The present invention is an improvement on the metal fittings for fixing wires to posts when stretching wire mesh on a fence.

In the figure, 1 is a fence post, 2 is an upper and lower rim, and 3 is an end rod that is inserted vertically into the wire mesh 6 at the side end thereof.

The present invention is used to fix the tension wire 13 shown in FIG. A semicircular arc surface is formed along the outer surface of the column, arc-shaped guide grooves 8, 8 for holding tension wires are bent out on the upper and lower edges, and bolt holes 10 are formed in the end pieces 9 forming both ends of the curved portion 7 by punching and bending. The hanging piece 11 is bent inward and protruded.

14 is a tension wire holder, and the tension wire 13 comes out from the guide groove 8 in Figs. 3 and 4.
Hold it in place while keeping it tense.

To use the present invention, as shown in Fig. 4, the end rod 3 is curved due to the tension of the wire mesh in Fig. 1 immediately after the wire mesh is stretched, so first hook the hook 11 onto the end rod. Next, hook the hanging piece on the other side to the end of the opposite side pulled to the column side, glue the tension wire restraint pieces 5, 5 along the pillar 1 from the inside and outside, and tighten the tension wire restraint 14. Insert it into the bolt 12 and temporarily fix it with the bolt 12.

Next, the tension wire 13 is stretched. The tension wire 13 is inserted through the opening in the tension wire holder 14, and the tension wire 13 is inserted through the opening. While the tension wire is pulled, the bolt 12 is attached to the corresponding inner and outer end pieces 9. ，
9, bring them close enough and tighten to final tighten.

Next, the tension wire 13 is placed in the guide groove 8, and the tension wire holder 14 at the other end is held in the same manner as described above.

Since the present invention is as described above, simply attaching the wire mesh to the fence posts 1 causes the end rods 3 to bend as shown in FIG.

In order to correct this, tension is applied in the lateral direction using tension wires 13.

In the present invention, when applying the tension wire 13, the bent end rods 3, 3 are pulled in advance by the hanging pieces 11 to reduce the tensile force of the tension wire 13.

Next, the tension wire is tightened with bolts and nuts through the tension wire restrainer, so the tightening force is small and the work is easy and quick.

Finally, it is stored in the guide groove 8, thereby protecting it from external damage and increasing the service life of the tension wire.

Therefore, compared to the conventional method in which the tension wire and the attachment of the tension wire to the fence posts are performed at the same time, the tension wire work is easier and faster, and the tension wire is securely fixed.

Claims (1)

[Claim for Utility Model Registration] A pair of tension wire restraining pieces to be installed on the inner and outer surfaces of the fence and the pillar have a curved part forming a semi-arc surface in the center, and end pieces extend parallel to both ends. In addition to providing tension wire guide grooves above and below the curved portion, a hanging piece to be engaged with the end rod inserted through the end of the wire mesh is protruded from inside the bolt hole portion of both end pieces, and a tension wire restrainer is inserted into the bolt.
