Furthermore, although this example shows an example in which two horizontal bars 2 are provided, one above the other, three or more horizontal bars 2 may be provided.

Reference numeral 6 denotes a vertical bar, and the vertical bar 6 has the following structure on the front side (or the rear surface) of the horizontal bar 2, so that the upper end of each vertical bar 6 protrudes above the horizontal bar 2 above. A large number of the vertical bars 6 are arranged and fixed so that the lower ends thereof protrude further downward than the lower horizontal bars 2. That is, as shown in FIGS. 3 and 4, the horizontal bar 2
On the mounting surface of the small vertical beam 6, that is, on the front in this example,
Two upper and lower horizontal bar protrusions 7 protruding toward the vertical bar 6 side,
8 is provided over almost the entire length of the horizontal bar, and on the other hand, on the surface of the small vertical bar 6 facing the horizontal bar, that is, the rear surface in this example, there are two left and right vertical bar protrusions 9, 10 that protrude toward the horizontal bar. Each of the vertical bar protrusions 9 and 10 is provided with two cuts 11 at the same height, with an interval equal to the distance between the two horizontal bar protrusions 7 and 8, and at two locations, upper and lower. , 12 are provided, and these notches 1
The deep portions 11a and 12a of the first and second portions 1 and 12 are formed in an enlarged shape so as to be close to the other notch side.

When fixing the small vertical bar 6 to the horizontal bar 2, as shown in FIGS.
12, and as shown in FIG. By caulking, the tips 7a, 8a of the horizontal bar protrusions 7, 8 are bent along the enlarged shape of the inner parts 11a, 12a of the cuts 11, 12, as shown in FIG. . As a result, the horizontal bar protruding portion 7,
8 are prevented from coming off through the notches 11 and 12, and the small vertical bars 6 are coupled to the horizontal bars 2.

FIG. 8 shows another embodiment of the present invention, in which an enlarged inner part 12a is formed only in one of the cuts 11 and 12, and the horizontal bar protrusions 7 and 8 are formed in the cut 11. , 12 and crimped, only the horizontal bar projection 8 bends along the curved part of the inner enlarged part 12a, and the small vertical bar 6 is fixed to the horizontal bar 2. . It is possible to prevent the fence from falling out with such a structure, and by curving only the lower horizontal bar protrusion 8 as in this example, when the fence is installed on a site, etc., it can be secured by caulking. There are no visible traces of pressure, which is aesthetically pleasing.

In addition, the horizontal bar protrusions 7 and 8 are as shown in FIG.
It may be provided protrudingly on the ventral surface 2a of the surface facing the small vertical bar 6, or a horizontal bar protrusion may be formed on the vertically protruding portion 2b, as shown in the tenth item 8.
In addition, the specific shape and structure of each part can be changed in various ways when implementing the present invention.

(Effect of the invention) As described above, in the present invention, the two upper and lower horizontal bar protrusions provided on the horizontal bar are replaced by the two upper and lower notches provided on the left and right vertical bar protrusions of the vertical bar. At the same time, the vertical bar is connected to the horizontal bar by crimping at least one of the two horizontal step protrusions with the enlarged deep part of the notch, and the horizontal bar is connected to the horizontal bar. There is no need for fixing devices such as screws as a means of connecting between the crosspiece and the two can be easily connected.
Suitable for mass production and can be provided at low cost.

Further, since the two horizontal bar protrusions and the two vertical bar protrusions are coupled in a state where they intersect at right angles, a strong coupling structure can be obtained.

In addition, as a structure in which two horizontal bar protrusions and two vertical bar protrusions intersect at right angles, a cut is provided in the horizontal bar protrusion and the vertical bar protrusion is fitted into the cut. However, with such a structure, a certain number of vertical bars are connected to a horizontal bar of a certain length, so the dimensional accuracy of the notch intervals must be high, and in some cases, large However, in the present invention, since notches are provided in the vertical bars, there is less requirement for dimensional accuracy, and the advantage is that manufacturing is easy and large equipment is not required. .

Also, Utility Model No. 60-75504 and Utility Model Application No. 60-
Publication No. 22649 shows a structure in which the upper and lower parts of the vertical bars are connected to the horizontal bars.According to this conventional structure, only two horizontal bars are provided at the top and the bottom. Horizontal bars can be joined above and below vertical bars. Moreover, as a result, it can also be used as a reinforcing material for tall fence bodies.

Furthermore, according to the structure described in each of the above-mentioned publications, after one end of all the vertical bars is connected to one horizontal beam, the other horizontal beam must be connected to the other ends of all the vertical bars at once. First, the assembly work is difficult, and moreover, the manufacturing precision of the joint portion is required.

On the other hand, in the present invention, the vertical bars can be connected to the horizontal bars one by one, the assembly work is easy, and manufacturing precision is not required.

In addition, the structures described in each of the above-mentioned publications are such that the groove or connecting piece of the vertical bar is fitted into a single protrusion provided on the horizontal bar or a groove provided in this. It becomes easy to bend, wobble, and rotate around the center of the vertical bar.

On the other hand, the present invention has a structure in which two protrusions are provided on each of the vertical and horizontal bars to connect them.
