Description

The present invention relates to fence joints, and more particularly to fence joints for securing mesh fence panels to posts.

A mesh fence is constructed by fixing a panel, which is made up of vertical bars and horizontal bars welded in a grid pattern, to posts via fence joints.

An example of a conventional fence joint will be described with reference to the drawings. Hereinafter, this conventional fence joint will be referred to as a conventional joint.

FIG. 10 is a front view showing a state in which the panel is fixed to the column by the conventional joint, FIG. 11 is a plan view showing the state in which the panel is fixed to the column by the conventional joint, and FIG. 12 is a panel fixed to the column by the conventional joint. FIG. 10 is a side view showing a state in which

10 to 12, reference numeral 11 denotes a panel made by welding vertical bars 12 and horizontal bars 13 in a grid pattern. A furring strip 14 of the panel 11 is formed by welding a horizontal bar 13 to the outside of the upper end of a vertical bar 12 bent into a ring shape. In addition, the furring strip of illustration shows an upper furring strip.

15 is a conventional joint for fixing the panel 11 to a post 16 made of a round pipe. The conventional joint 15 consists of an insertion portion 17 inserted into the furring strip 14 and a fixing portion 18 fixed to the strut 16 . A part of the insertion portion 17 is punched out by a press to form a threaded portion 19 for a screw, which will be described later. A bolt hole 20 is formed in the insertion portion 7 and a bolt hole 21 is formed in the fixed portion 18 .

In order to fix the panel 11 to the post 16 by the conventional joint 15 configured in this way, the insertion portion 17 of the conventional joint 15 is inserted into the furring strip 14 of the panel 11, and the fixing metal fitting 22 is applied to the furring strip 14. , the screw 23 is screwed into the threaded portion 19 of the insertion portion 17 through the fixing bracket 22 .

After the conventional joints 15 are fixed to the furring strips 14 of the left and right panels 11 in this way, the bolts 24 are passed through the bolt holes 21 of the fixing portions 18 of one of the conventional joints 15 and through the posts 16, and then the fixing portions 18 of the other conventional joint 15 are attached. and tighten the nut 25. The panel 11 is thereby secured to the post 16 by conventional joints 15 .

As described above, the panel 11 can be fixed to the column 16 with the conventional joints 15, but two joints are required. Therefore, it is desired to reduce the number of joints and improve workability.

One embodiment of the joint for fences of the present invention will be described with reference to the drawings.

FIG. 1 is a front view showing the joint for fence of the present invention, FIG. 2 is a plan view showing the joint for fence of the present invention, FIG. 3 is a side view showing the joint for fence of the present invention, and FIG. FIG. 5 is a rear view showing the fence joint of the invention, and FIG. 5 is a sectional view taken along line AA of FIG.

In FIGS. 1 to 5, 1 is a plate-shaped joint body having a laterally long bolt hole 2 formed in the center in the longitudinal direction. It is a nut that passes through the joint body 1 and is fixed by caulking. The reason why the bolt holes 2 are elongated is to adjust the mounting of the joint body 1 .

An attachment portion (S) of the longitudinal central portion of the joint body 1 to the strut 4 (see FIG. 2) is curved in the longitudinal direction of the joint body 1 in an arc shape. The curvature of the mounting portion (S) is formed larger than the curvature of the strut 4 . As a result, a gap (L) is formed between the post 4 and the mounting portion (S), so that it is possible to accommodate the tilted installation of the panel 11, which will be described later.

Both sides of the joint body 1 are arcuately curved in the width direction of the joint body 1 . As a result, the strength of the joint main body 1 can be increased, and the joint main body 1 and the furring strip 14, which will be described later, come close to each other, thereby improving the appearance. The joint main body 1 is formed with reinforcing ribs 5 on the upper and lower sides, and the joint main body 1 is also reinforced by these ribs.

In order to fix a panel to a post by means of the joint of the present invention constructed as described above, the joint body 1 is applied to the post 4, and the bolt 6 is formed on the post 4, as shown in FIGS. The bolt hole 7 is passed through the bolt hole 2 of the joint body 1, and the nut 8 is tightened.

The panel 11 is formed by welding the vertical beams 12 and the horizontal beams 13 in a grid-like manner in the same manner as the above-described panel. It is formed by welding a crosspiece 13 to the outside of the .

After fixing the joint main body 1 to the strut 4 in this manner, one side of the joint main body 1 is inserted into the furring strip 14 of the panel 11 . As an insertion method, a method of inserting the joint body 1 into the furring strip 14 through a gap (m) (see FIG. 8) formed in the furring strip 14 is adopted.

Next, the fixing metal fitting 9 is applied to the furring strip 14, and the bolt 10 is screwed into the nut 3 through the fixing metal fitting 9 formed with the long hole 9a. The panel 11 is thereby secured to the post 4 by the joint of the invention. By doing this for the left and right panels 11, a mesh fence can be constructed.

As described above, according to the present invention, the panel 11 can be fixed to the post 4 with one joint, so the number of joints can be reduced and the joint body 1 can be provided with a nut function. By doing so, it is possible to improve workability.

Further, according to the present invention, by curving both sides of the joint main body 1 in an arc shape in the width direction of the joint main body, the strength of the joint main body 1 can be increased and the appearance of the joint main body 1 can be improved.

Further, according to the present invention, the attachment portion (S) of the joint main body 1 in the longitudinal direction central portion to the strut 4 is curved in the longitudinal direction of the joint main body 1 in an arc shape, and the curvature thereof is made larger than the curvature of the strut 4. Accordingly, it is possible to cope with the inclined installation of the panel 11 .
