Description

[Detailed Description of the Invention] The present invention relates to an attachment device for attaching a wire mesh to a side frame (trum) in a wire mesh fence.

In order to attach a wire mesh to a crossbeam in a wire mesh fence, a mounting device as shown in FIG. 1 has conventionally been generally employed. That is, by cutting and bending the crosspiece 1 at appropriate intervals to form hook pieces 1A, and hooking the wire 3 threaded through the wire mesh 2 onto the hook pieces 1A, the wire mesh 2 is attached to the crosspiece 1. It is installed on.

In such a mounting device, if the wire mesh 2 gradually loosens from its initial tension state over time or due to repeated shock loads,
The hook state of the wire 3 on the hook piece 1A also becomes loose and easily comes off. Since the hook piece 1A is formed by cutting and bending the crosspiece 1, it is not easy to bend it after hooking to prevent the wire 3 from coming off. For this reason, it has been difficult to prevent the wires from coming off due to deformation of the wire mesh over time.

The object of the present invention is to provide a device for attaching a wire mesh to a crossbeam which eliminates these drawbacks.

To this end, the present invention uses a hollow pipe material with an oval cross section with high bending rigidity to create a net holder, and with this net holder threaded through the wire mesh, it is attached to the side beams using bolts and nuts. It is characterized by being fixed.

Examples will be described below with reference to the drawings.

In the embodiment shown in FIGS. 2 and 3, the crosspiece 10 does not have a mounting piece formed by cutting and bending like the hook piece 1A in FIG. is formed.
The wire mesh 2 is the same as in FIG. As a feature of the present invention, a hollow net holder 12 with an oval cross section is shown threaded through the wire mesh 2. The net holder 12 is made of steel, and has such a cross-sectional shape that it has high bending rigidity and can be easily fixed with the bolts 11. For fixing with the bolts 11, the net holder 12 is also formed with holes 12A for bolt insertion, corresponding to the holes 10A of the crosspiece 10.

Installation of the wire mesh 2 in this configuration is completed as shown in the figure by inserting the net holder 12 into the wire mesh 2, inserting the bolts 11 into the holes 10A and 12A of the crosspiece 10 and the net holder 12, and screwing the nuts 13. do. Of course net holder 12
Bolts 11 and nuts 13 are similarly arranged at appropriate intervals along the longitudinal direction of the holder.

According to this configuration, the net holder 12 has a hollow shape with an elliptical cross section and therefore has high bending rigidity.
The straight state can be maintained by mounting with bolts 11 and nuts 13, which not only provides an excellent appearance but also makes the mounting work extremely easy. Furthermore, the wire mesh can be completely prevented from coming off, making it sufficiently durable for long-term use.
