Description

[Detailed description of the invention] As shown in Fig. 1, the wire mesh fence consists of a wire mesh 1,
It is composed of a furring 2 that supports the wire mesh 1 at its upper and lower ends, and struts 3 that support the furring 2. The connection between this rim 2 and the strut 3 is a joint 4'.
It is carried out by

The joints 4' include an upper intermediate joint 40' that supports the rim 2 on both sides of the column 3, a lower intermediate joint 41', and an upper end joint 42' that supports the rim 2 on one side of the column 3. ,
It is divided into lower end joints 43', each having a different configuration. These joints 4' fit the cylindrical furrow fitting part 10' into which the furrow 3 is fitted, and the strut 3, and the strut fitting part 1 which is a connecting part that connects the struts.
It has a tubular structure with 1'. There are two furring fitting parts 10' at the upper intermediate joint 40' and lower intermediate joint 41', one at the upper end joint 42' and lower end joint 43', and the strut fitting part 11 is at the upper intermediate joint 41'. 1 piece at joint 40' and upper end joint 42',
Lower intermediate joint 41' and lower end joint 4
3', two are formed.

By the way, the wire mesh fence having the above-mentioned structure is normally installed in a straight line, but when it is bent, it is necessary to prepare a special bending joint. However, in actual installation work, there are many cases where slight bending is required, and there is no need to use a bending joint, so if a certain degree of bending can be achieved using a normal joint, the effect would be very large. becomes.

This idea was made to improve the above-mentioned drawbacks of the conventional wire mesh fence, and aims to provide a wire mesh fence that can be bent by about 10 to 15 degrees, which was impossible with conventional wire mesh fences. This is the purpose. Therefore, the basic feature of this invention is that the inner diameter of the intermediate joint, excluding the end, is enlarged to make the diameter larger, and the sleeve can be bent horizontally to fit. It is.

An embodiment of the present invention will be described below based on the drawings.

FIG. 2 is a plan view of the structure, showing the structure bent at an angle of about 10 degrees.

FIG. 3 is a horizontal sectional view of the upper intermediate joint 40, in which the side surfaces 12 and 13 of the furring fitting portion 10 are inclined at a predetermined angle. That is, one side surface 12 forms a straight portion 120 at its end, but forms an inclined portion 121 that slopes upward in the drawing toward the center. One side of the other side 13
Similarly, a straight portion 130 and an inclined portion 131 which is inclined vertically in the drawing are formed. Inclined part 1
21, 131 terminate in a central straight section 122, 132 in this embodiment. Due to these inclined parts 121 and 131, the inner diameter of the furring fitting part 10 is gradually expanded from the end toward the back, and becomes larger in diameter.

The length m of the straight portion 120 and the straight portion 130 is the total length
In contrast to L140-150mm, in this example it is 15mm. In addition, the length n of the straight parts 122 and 132 is 20
mm.

The inclination angle a of the inclined portion 121 and the inclined portion 131 is 4 degrees in this embodiment. These specific lengths and angles may be determined as appropriate depending on the diameters and lengths of the struts 3 and the trunk 2.

FIG. 4 is a horizontal cross-sectional view of the lower intermediate joint 41, showing side surfaces 12 and 13 of the furring fitting portion 10.
, a straight section 120, an inclined section 121, and a straight section 130.
and an inclined portion 131 are formed, respectively.

In the above configuration, the furring 2 fitted to the joint 4 has the inclined portion 121 or the inclined portion 13.
Since it can be tilted according to the slope 1, the furring 2 can be bent here. Therefore,
A bent wire mesh fence is not required except in special cases.

FIG. 5 is a horizontal sectional view showing another embodiment of the upper intermediate joint 40, in which the inner diameter of the furring fitting portion 10 is larger than the outer diameter of the furring 2, forming a large diameter portion 20. . A small diameter portion 21 is further formed at the end of this furring fitting portion 10. In this embodiment, the small diameter portion 21 is a protruding piece that protrudes in the inner diameter direction at the end of the furring fitting 10. The inner diameter of the small diameter portion 21 is approximately the same diameter as the outer diameter of the barrel rim.

FIG. 6 is a horizontal sectional view of the lower intermediate joint 41, in which the inner diameter of the furring fitting portion 10 is a large diameter portion 20 larger than the outer diameter of the furring 2. FIG. Further, a small diameter portion 21 is formed at the end thereof. In the above configuration, the furring 2 fitted into the joint 4 is supported by the small diameter portion 21;
Since the distal end portion is free, it can be bent by the difference between the diameter of the large-diameter portion 20 and the diameter of the rim 2.

As mentioned above, the wire mesh fence of the present invention has an enlarged inner diameter excluding the end of the joint where the rim fits, so the rim can be bent in the horizontal direction accordingly. , which was previously impossible
It has the advantage that it can be installed with a bend of about 10 to 15 degrees.
