Description

[Detailed description of the invention] [Industrial application field] This invention relates to a net fence made by stretching a net made of vertical and horizontal bars welded between upper and lower furring strips.

[Prior art and problems to be solved] Conventionally, in a net fence in which this type of net is stretched between the upper and lower body edges, the upper and lower ends of the vertical bars forming the net are connected by using metal fittings or by directly welding them. The net was stretched by connecting it to the upper and lower body edges using methods such as tying.

However, both the cases of using metal fittings and the cases of direct welding have the disadvantage that it takes a lot of effort to stretch the net. Furthermore, when the ends of the vertical rods are directly welded and fixed, there is a problem that the nets are likely to fall off or bend.

[Means for Solving the Problems] The present invention solves the above-mentioned conventional problems in a net fence in which a net made by welding a vertical bar and a horizontal bar is stretched between the upper and lower body edges. In addition to providing the above-mentioned horizontal bar on one side or both sides of the end,
The end of the vertical bar protrudes from the horizontal bar by approximately the diameter of the horizontal bar, and the upper and lower furring edges are formed completely hollow, and the lower and lower parts of the hollow part of the upper furring edge are formed. In the upper part of the hollow part of the body rim, a fitting groove part is provided in which the upper and lower edges of the net are slidably fitted, and the fitting groove parts are provided at the bottom and on both left and right sides, and the fitting groove parts are provided at the bottom and on both left and right sides, and the fitting groove parts are provided at the bottom and on both left and right sides. It is configured to form a recess into which the horizontal bar is fitted.

[Example] Hereinafter, an example of the present invention will be described in detail with reference to the drawings.

FIGS. 1 to 4 show a network system according to an embodiment of the present invention.

The net fence of this embodiment is constructed by fixing laterally extending furrows 5 and 6 to pillars 20 which are erected at appropriate intervals, and by stretching the net 1 between the furrows 5 and 6.

The net 1 has a vertical bar 2 and a horizontal bar 3 made of steel.
It is constructed by assembling them in a lattice shape and welding their intersections. In Net 1 above,
A horizontal bar 3 is provided on one side near the upper and lower ends of the vertical bar 2,
As shown in the figure, the upper and lower ends 2a and 2b of the vertical bar 2 are connected to the horizontal bar 3.
It is made to protrude by a predetermined length in the vertical direction. Then, horizontal bar 3 and vertical bar 2 on both sides of this upper and lower end
The upper and lower end portions 2a and 2b form fitting portions for the upper and lower edges of the net 1 to the furring edges 5 and 6.

The flanges 5 and 6 support the upper and lower edges of the net 1, and are formed in a hollow shape with a rectangular cross section as shown in the figure. Therefore, it is fixed to the support column 20. In addition, the length of the furring edges 5 and 6 is the same as that of the net 1.
It is made almost equal to the left and right width of .

Fitting grooves 7, 7 into which the upper and lower edges of the net 1 are slidably fitted are integrally formed on one side of the upper and lower furring edges 5, 6.

The fitting groove 7 is provided in the longitudinal direction of the flanges 5 and 6, and has a U-shaped recess 8 in cross section located at the center of the bottom and into which the upper and lower ends 2a and 2b of the vertical bar 2 are fitted. , has recesses 9, 9 located on both the left and right sides of the recess 8, into which the horizontal bars 3 at the upper and lower ends of the net 1 are fitted.

Here, the recess 8 is formed to have a width approximately equal to the diameter of the upper and lower ends 2a, 2b of the vertical bar 2 protruding from the horizontal bar 2 at the upper and lower ends, and a depth approximately equal to the length of the upper and lower ends 2a, 2b. There is. In addition, the recesses 9, 9
has a U-shaped cross section that allows the horizontal bar 3 to fit in any direction, and is formed symmetrically with an interval approximately equal to the diameter of the vertical bar 2.

The flanges 5 and 6 are fixed to the support column 20 with their fitting grooves 7 and 7 facing downward and upward, respectively, and facing each other. Then, the net 1 inserts the upper and lower ends 2a, 2b of the vertical bar 2 into the recesses 8, 8 of the fitting grooves 7, 7 of the upper and lower furring edges 5, 6.
By slidingly fitting the horizontal bars 3, 3 at the upper and lower ends into the recesses 9 of one of the fitting grooves 7, 7, the flanges 5, 6 are stretched in the longitudinal direction as shown in the figure.

Furthermore, the mounting bracket 15 for fixing the furring 5 to the support column 20 is formed into a substantially L-shape as shown in the figure.
The furring 5 is held against the struts 20 by gripping the furring 5 from above. Further, the mounting fittings 16 of the furring 6 are shaped to receive and hold the furring 6 from below.

Further, the furring edges 5 and the furring edges 6 are connected to each other by a short connecting member 17 and extend in the lateral direction.

In addition, in the above embodiment, the recess 9 of the fitting groove 7,
9 are formed symmetrically on the left and right sides of the recess 8. By forming the nets 9 symmetrically on the left and right sides of the recess 8, it is possible to fit the net 1 without considering the orientation of the furring edges 5 and 6. The furring can be used as is for the upper and lower furrings 5 and 6.

In addition, although the case where the horizontal bar 3 is provided on one side of the upper and lower ends of the vertical bar 2 is shown, two horizontal bars 3 are provided facing each other on both sides of the upper and lower ends, and the two horizontal bars 3 are fitted. It may be slidably fitted into the left and right recesses 9, 9 of the groove 7.
Furthermore, the shapes of the furrings 5 and 6 and the method of fixing them to the support columns 20 are not limited to those of the above embodiments. Incidentally, the furring edges 5 and 6, the struts 20, etc. are formed using extruded materials such as aluminum.

[Effects of the invention] As explained above, the NetFence of the invention has horizontal bars on one or both sides of the upper and lower ends of the vertical bars, and the ends of the vertical bars are made to protrude beyond the horizontal bars.
The upper and lower body edges are provided with fitting grooves into which the upper and lower edges of the net are slidably fitted, and the fitting grooves have recesses at the bottom and on both left and right sides into which the ends of the vertical bars and the horizontal bars at the upper and lower ends fit. By forming the net, the net can be stretched between the furring edges with a simple operation of slidingly fitting the upper and lower edges of the net.

Furthermore, in the invention of the present application, by forming the furring rim in a completely hollow shape, there is an effect that the furring rim is structured strongly. Moreover, since the fitting groove is also formed integrally with the furring at this time, there is an effect that not only the fitting groove but also the fitting groove is formed firmly. In addition, since the protruding dimension of the end of the vertical bar is short, it is easy to perform the net tensioning work, and the end of the vertical bar is not easily deformed even before sliding fitting.

On the other hand, in the present invention, by forming recesses at the bottom of the fitting groove and on both left and right sides, both horizontal bars can be fixed even in a net having horizontal bars on both sides. Therefore, such a net can be fixed more firmly. Moreover, this recessed portion has the effect that in the case of a net having a horizontal bar on one side, the net can be slidably fitted regardless of whether the horizontal bar is on either side. Therefore, there is no need to carry out the tensioning work while checking the front and back sides of the net surface, and work efficiency can be further improved.
