Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial application] The present invention relates to a net fence having a net formed by arranging a large number of thin net rods in an intersecting shape and welding the intersecting portions.

[Prior Art] Conventionally, a net fence of this type has been constructed by directly fastening a net made up of a large number of net thin rods to a column that is erected at appropriate intervals by a fastener such as a clip.

[Problems to be Solved by the Invention] In the above-described conventional net fence, the net is directly attached to the support, so that the net is supported only by the attachment part of the support, and the space between the support Since it is not supported at the part of, the net has the defect that it bends when the distance between the columns is large.

In order to prevent such bending of the net, it is necessary to reduce the interval between the columns, and there is a disadvantage that a large number of columns must be installed.

[Means for Solving the Problems] In the present invention for solving the above-mentioned conventional problems, a thin net bar composed of a vertical bar and a horizontal bar is welded and fixed to upper and lower bars arranged at predetermined upper and lower positions. Are attached to columns that are erected at appropriate intervals.

More specifically, a net formed by arranging a number of vertical thin rods and horizontal thin rods in an intersecting shape and welding the intersecting portions is provided, and the upper and lower edges of the net are formed. Each has a folded edge that is folded back in the same side direction,
A hollow upper and lower bar is attached to one side of the net, and the expected width of this upper and lower bar corresponds to the folded width of the above-mentioned folded edge portion. The lower bar is arranged above the folded-back edge of the lower edge of the net, and the net contact portions of the upper and lower bars are welded to the net thin rods contacting the upper and lower bars. The nets are attached to the pillars standing upright at appropriate intervals via the upper and lower crosspieces.

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

1 to 5 show a net fence according to an embodiment of the present invention.

In the net fence of the present embodiment, basically, the net 1 made of a net thin rod is welded and fixed to the upper and lower bars 2a and 2b extending in the lateral direction, and the upper and lower bars 2a and 2b are erected on the pillars 3 standing at appropriate intervals. Installed and configured.

The net 1 is constructed by arranging and assembling net thin rods composed of a large number of vertical rods 11 and horizontal rods 15 in a cross shape, and welding and fixing the respective crossing portions 13 thereof. In the net 1, the vertical bar 11 is bent at a wider angle from the vicinity of the upper and lower ends, and the upper and lower ends of the vertical bar 11 are folded back so that the upper end is downward, and the lower end is upward. The folded back edge portions 12a and 12b are respectively formed. The horizontal bars 15 at the upper and lower edges of the net 1 are arranged in correspondence with the shapes of the folded edge portions 12a and 12b.

The folded edge portions 12a, 12b of the net 1 are folded in the same lateral direction, and the folded widths of the folded edge portions 12a, 12b and the expected widths of the upper and lower bars 2a, 2b correspond to each other.

The upper and lower crosspieces 2a, 2b are attached at predetermined upper and lower positions of the net 1, respectively, and the upper crosspiece 2a is arranged below the folded edge portion 12a of the upper edge of the net 1 and the lower crosspiece 2b is arranged on the lower edge of the net 1. It is arranged above the folded edge 12b. The upper and lower bars 2a and 2b are
As shown in the drawing, it is formed in a hollow shape having a rectangular cross section, and a U-shaped connecting portion 22 is projected from the side surface on the side of the column 3. The upper and lower rails 2a and 2b fix the net 1 at the net contact portion 21 by welding a thin net rod in contact with the upper and lower rails 2a and 2b. The upper and lower rails 2a, 2b are fixed to the column 3 by engaging the U-shaped portions of the connecting portions 22 with the mounting brackets 4a, 4b and screwing one end of the mounting brackets 4a, 4 together. There is. The length of the upper and lower crosspieces 2a, 2b is substantially equal to the lateral width of the net 1.

The columns 3 and the upper and lower crosspieces 2a, 2b are formed of an extruded material such as aluminum.

As shown in FIG. 2, the net fence of the present embodiment is configured by arranging the nets 1 in upper and lower two stages. However, depending on the height of the support column 3, the nets 1 may be provided in one stage or three or more stages. May be arranged.

The method of fixing the net 1 to the upper and lower bars 2a and 2b, and the method of attaching the upper and lower bars 2a and 2b to the support column 3 are not limited to those in the above embodiment. Further, although the vertical bars 11 of the net 1 are arranged vertically in the present embodiment, they may be arranged parallel to each other in the oblique direction.

As described above, in this embodiment, the nets 1 are attached to the upper and lower crosspieces 2a and 2b by welding and fixing the net thin rods that abut the net abutting portions 21, respectively. Since it can be supported at a large number of welding points, the bending of the net 1 can be prevented.

[Effects of the Invention] As described above, the net fence of the present invention is configured such that the thin net bar composed of the vertical bar and the horizontal bar is welded and fixed to the upper and lower bars arranged at predetermined upper and lower positions, and the upper and lower bars are appropriately arranged. Since the nets are attached to the columns via the upper and lower rails to which the thin nets are welded and fixed, the nets can be supported at multiple supporting points in the lateral direction. Therefore, there is an effect that the bending of the net can be prevented.

Further, since the net is supported by the hollow upper and lower crosspieces and the bent portions by the folded edge portions are arranged at the upper and lower edges of the net, the net can be reinforced against the force from the upper, lower, left and right sides. There is an effect that strength and safety can be improved.

Further, since the folded edge portions of the upper and lower edge nets are arranged above and below the upper and lower bars, respectively, and the folded width and the expected width of the upper and lower bars are made to correspond to each other, the upper and lower bars have sufficient strength. On the other hand, there is an effect that the appearance of the net fence is further improved by staying within the folded width of the folded edge.
