Description

[Detailed description of the invention] The present invention provides a fence formed by intersecting a horizontal bar 1 and a vertical bar 2, in which protrusions 3 are provided that extend in the longitudinal direction near the upper and lower ends of the horizontal bar 1, This relates to a fence made by pressure-welding vertical bars 2 to protrusions 3 provided near the upper and lower ends, respectively, and its purpose is to ensure strong adhesion between the vertical bars and horizontal bars. The vertical bars can be fixed at appropriate positions in the longitudinal direction of the horizontal bars, rainwater does not accumulate at the joint between the horizontal bars and the vertical bars, and the protrusions serve as decorative lines for the horizontal bars and reinforcing ribs. To provide a fence that can serve both of the functions of a projection and a projection.

The present invention will be explained in detail by way of examples.

1 in the figure is a horizontal crosspiece formed from a square metal pipe,
Continuous protrusions 3 extending along the entire length in the longitudinal direction near the upper and lower ends of one side of the horizontal beam 1 are formed by roll forming or the like.

However, the vertical bar 2 formed by a metal square pipe on the horizontal bar 1
Fence A is formed by intersecting them.

In this case, since the protrusion 3 is formed over the entire longitudinal length of one side of the horizontal beam 1, the vertical beam 2 can be projection welded at any position in the longitudinal direction of the horizontal beam 1, and the welding strength is The same strength can be achieved at any position in the longitudinal direction of the sheet.

If necessary, as shown in FIG.
Alternatively, the material may be pressure-welded and welded by projection welding.

In this way, the current and pressing force can be further concentrated, and the welding strength can be increased.

As described above, the present invention is a fence formed by intersecting horizontal bars and vertical bars, in which continuous protrusions are provided in the longitudinal direction near the upper and lower ends of the horizontal bars, and protrusions are provided near the upper and lower ends, respectively. Since the vertical bars are pressure-welded to the ridges and projection welded, even if one of the welds comes off, the fence retains its fence shape.Also, the ridges are provided near both the top and bottom ends of the horizontal bars to prevent projection welding. Because it is welded, the horizontal beam is supported at both ends, making it strong and strong.Furthermore, since we have provided protrusions near both the top and bottom ends of the horizontal beam, there is a gap between the horizontal beam and the vertical beam, which prevents it from being exposed to rainwater. However, water will not accumulate in that area, and the horizontal and vertical beams will be less susceptible to rust over the long term.

In other words, with conventional fences in which both the vertical and horizontal beams are in contact and are partially welded by fillet welding, when exposed to rain, capillary action occurs in the non-welded areas where the two sides are in contact. The present invention solves the drawbacks of conventional fences, as they allow water to get in and accumulate, making them prone to rust over the long term.

Furthermore, since the protrusions are provided near the upper and lower ends of the horizontal bars, the protrusions serve as reinforcing knobs for the horizontal bars, further improving the strength of the fence.

Furthermore, since the protruding stripes are provided continuously in the longitudinal direction of the horizontal bar, the protruding strips also serve as lines for decorating the horizontal bar, and the vertical bar can be projection welded to any position on the horizontal bar. It is possible to construct a fence with any vertical beam gap, and if you look at it from a different perspective, the ridges, which are decorative lines for the horizontal beams and reinforcing ribs, are used for projection welding, so the ridges can be Not only can it serve three purposes, and the current and pressure are concentrated to ensure strong fixing, but the protruding stripes are provided along the entire longitudinal length of the horizontal crosspiece, making it easier for the horizontal crosspiece to Projection welding can be performed no matter where the vertical bars are welded in the longitudinal direction, and there is an advantage that even rotation with high strength can be achieved even if the vertical bars are welded at different positions.
