Description

[Detailed explanation of the idea] This invention relates to the improvement of wire mesh fences.

For example, as described in Japanese Utility Model Application Publication No. 57-131949, it has a support with an L-shaped hook on the side, a wire mesh with a frame around which a horizontal frame and a vertical frame are attached; A wire mesh fence is known in which a framed wire mesh is attached between adjacent posts by providing mounting holes at the ends of the horizontal frames of the wire mesh and inserting and fixing the hooks into the mounting holes.

However, conventional wire mesh fences of this type have had the following problems.

a. Since the framed wire mesh is supported only by the mounting portion facing in the perpendicular direction at the end of the hook, this mounting portion is likely to bend when a large load from the framed wire mesh is applied.

b. Because the hooks protrude along the sides of the horizontal frame, depending on where the wire mesh fence is installed, it may not be aesthetically pleasing.

The object of the present invention is to provide a wire mesh fence that increases the supporting strength of the hook and at the same time prevents the hook from protruding from the side of the horizontal frame.

In order to achieve this purpose, the wire mesh fence of the present invention includes a wire mesh with a frame having a horizontal frame and a vertical frame around the wire mesh, a main body part parallel to the horizontal frame of the wire mesh with a frame, and a mounting part perpendicular to the horizontal frame. A mounting hole is provided at the end of the horizontal frame of the wire mesh with a frame, and the mounting portion of the hook is inserted and fixed into the mounting hole, so that the adjacent In the case where a wire mesh with a frame is attached between the supports, a groove is provided on the side surface of the horizontal frame of the wire mesh with a frame to fit the main body of the hook and prevent the hook from swinging or rattling. It is characterized by:

Hereinafter, an embodiment of the present invention will be described in detail based on the drawings. In Fig. 1, 1 indicates columns erected at regular intervals, and 2 indicates a wire mesh with a frame attached between adjacent columns 1. ing.

The above-mentioned support 1 is constructed of a metal pipe, and the upper and lower sides of the support 1 are shown in FIGS. 2 and 3.
As shown in the figure, the L
The letter-shaped hooks 3 and 3 are fixed. This hook 3 consists of a main body portion 3a parallel to the framed wire mesh 2, and a mounting portion 3b perpendicular to the framed wire mesh 2.
A screw is cut into b so that a nut 4 can be screwed into it.

Further, the framed wire mesh 2 has a horizontal frame 6 and a vertical frame 7 having a groove-shaped cross section attached around the wire mesh body 5, and these horizontal frames 6 and vertical frames 7 are attached to the upper and lower ends of the vertical frame 7. are inserted into the horizontal frame 6 and connected in a rectangular frame shape by fixing them by means such as welding,
As shown in FIGS. 2 to 4, at the end of the horizontal frame 6 (FIG. 5) having a narrow width portion 6a at the center, the horizontal frame 6
A long mounting hole 8 is bored in the axial direction of the horizontal frame 6, and a part of the side wall of the narrow portion 6a is bulged outward at a position overlapping the mounting hole 8 on one side of the horizontal frame 6. Therefore, a long concave groove 9 is formed in the axial direction of the horizontal frame 6 into which the main body 3a of the hook 3 can be inserted without rattling, and a narrow groove 9 is formed on the other side of the horizontal frame 6. A flat portion 10 is formed around the mounting hole 8 by bulging a portion of the side wall of the portion 6a outward. Then, the groove 9
With the body portion 3a of the hook 3 fitted therein, the attachment portion 3b of the hook 3 is inserted into the attachment hole 8, and the nut 4 is screwed onto the attachment portion 3b from the flat portion 10 side.

Here, if friction portions 11 and 12 are provided by unevenness on the side surface of the horizontal frame 6 in the groove 9 and the side surface of the main body portion 3a of the hook 3 that abuts thereon, respectively, these hooks 3 and the horizontal frame 6, the framed wire mesh 2 can be stably fixed by preventing slippage between the main body 3a of the hook 3 and the horizontal frame in the groove 9, as shown in FIG. A friction member 13 made of metal, synthetic resin, or the like can also be interposed between the contact member 6 and the contact member 6 . In this case, the friction portion 1 as described above is provided on the contact surface between the horizontal frame 6 and the friction member 13.
4 and 15 may be provided.

Note that instead of being provided in the groove 9, the friction part 11 may be provided in the flat part 10 that the nut 4 comes into pressure contact with to prevent slippage between the nut 4, or It can also be provided on both the flat part 10 and the flat part 10.

Further, the wire mesh body 5 may be formed of a welded wire mesh, a crimped wire mesh, or the like, in addition to the illustrated expanded metal wire mesh.

As described above, according to the present invention, a concave groove is provided on the side surface of the horizontal frame of the wire mesh with a frame, and the hook and the wire mesh with a frame are connected with the main body of the hook fitted into the groove. Therefore, the above connection can be performed stably by preventing the hook from swinging or rattling, and the load of the wire mesh with frame is distributed and acts not only on the attachment part at the end of the hook but also on the main body. Therefore, bending, twisting, etc. of the attachment part can be prevented, and furthermore, since the main body part of the hook does not protrude from the side surface of the horizontal frame, the appearance of the wire mesh fence is not spoiled.
