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. Furthermore, since the edges of the wire mesh were exposed, there were problems such as clothes getting caught and getting damaged or injured.

The object of the invention is to provide a wire mesh attachment device that eliminates these drawbacks.

For this purpose, in the present invention, a net holder 10 is applied from above the wire mesh 2 along the edge of the wire mesh 2, and the net holder 10 is fixed to the crosspiece 20 having an L-shaped cross section with bolts 30 and nuts 31. The net holder 10 is a mounting device, and the net holder 10 is
A portion 10B that abuts the bottom side of the wire mesh 2 and a covering portion 10A that forms a space between it and the crosspiece 20 to receive the edge of the wire mesh 2 and cover the surface of the edge of the wire mesh 2 are bent in series. A spring 50 is inserted into the edge of the wire mesh received in the space, a bolt 30 is inserted inside the wire 50, and a nut 31 is positioned in the groove. It is characterized in that it is fastened and fixed to the horizontal beam 20.

Embodiments of the present invention will be described below with reference to FIGS. 2 and 3.

Net holder 10 shown in FIGS. 2 and 3
is formed as an elongated member having a substantially L-shaped cross section with grooves formed on its surface. This net holder 1
0 has a covered part 10A positioned on the surface of the wire mesh 2 and a part that comes into contact with the crossbar, that is, a leg part 10B, and the covered part 10A has a nut 31 to be described later. In order to avoid protrusion, a groove 10C is formed deep enough to sink the nut 31.

Insertion holes 11 for bolts 30 are formed at appropriate intervals in the covered portion 10A of the net holder 10. On the other hand, the horizontal arm 20 is similarly formed with an insertion hole 21 for a bolt 30 instead of the hook piece 1A in FIG. Thereby, the net holder 10 can be fixed to the side beam using the bolt 30 and nut 31.

The edge of the wire mesh 2 is inserted into the groove space 40 formed by the net holder 10 as shown in FIG. 2, and in this state the net holder 10 is fixed with the bolts 30 and nuts 31. Here, the bolt 30 is inserted inside the wire 50 that is inserted through the wire mesh 2. Furthermore, it is preferable that the wire be inserted through a closed eye in the wire mesh 2.

According to the mounting device configured in this way, the wire mesh 2 is screwed into the bolt 30 by the nut 31.
The end surface of the net is held between the crosspiece 20 and the net holder 10. In addition, 30 bolts
is inserted inside the wire 50, preferably through the closed mesh of the wire mesh 2, to more reliably prevent the wire from being pulled out. In this way, the edge of the wire mesh 2 is fixed to the crossbar 20.

As described above, according to the mounting device of the present invention, it is possible to fix the wire mesh to the crossbar without exposing the edge of the wire mesh, and since the net holder used for this purpose has a cross-sectional shape with high bending rigidity, bolts and Fixation with nuts prevents the edges from becoming wavy. This not only improves the appearance, but also prevents damage to clothes, etc., since the nut portion is located in the groove on the surface of the net holder.
