Description

  The present invention provides a structure for fixing an existing fence and an upper joint metal fitting, in particular, when using an existing fence post made of hat-shaped steel as it is and remodeling an existing fence into a new fence, It is related with the fixing structure of the existing support | pillar and an upper joint metal fitting which can fix the upper joint metal fixture fixed to the existing support | pillar reliably by one touch.

  There is a net fence as a fence that has been widely constructed. As shown in FIGS. 7 and 8, the net fence is composed of a pillar 1 made of hat-shaped steel, an upper part made of angle steel fixed between the pillars 1, and a lower trunk edge 2 (only the upper trunk edge is shown). And a rhombus wire mesh 3 attached between the upper and lower waist edges 2. The upper trunk edge 2 is attached to the upper end portion of the rhombus metal mesh 3 by hooking an iron wire 4 inserted through the upper end portion of the knuckle-shaped rhombus metal mesh 3 onto a claw 2A formed at a vertical portion of the upper trunk edge 2. Yes. The attachment of the lower trunk edge to the rhombus metal mesh 3 is the same as that of the upper trunk edge except that the direction of the claw 2A is upside down.

  The vertical part of the upper trunk edge 2 is inserted into an upper claw 1A formed at the upper part of the lip of the support column 1, and the horizontal part of the upper trunk edge 2 is fixed to the fixing bracket 6 by a bolt 5 inserted through the web of the support column 1. It is fixed through. The fixing bracket 6 has a groove 6 </ b> A into which the horizontal portion of the upper trunk edge 2 is fitted, and is fixed by a cap nut 7. The structure of fixing the lower trunk edge to the support column 1 is the same as that of the upper trunk edge except that the direction of the upper claw 1A is upside down.

  In the case of a net fence constructed in this way, when the years have passed, the aesthetics are significantly impaired due to rust generated on the support pillars 1, the torn or deformed rhombus wire mesh 3, and in some cases the function as a fence is lost. There is also.

  It is best to reconstruct a fence having such a defect, but since it is expensive to construct, it is advantageous to replace only the damaged part with a new member. Therefore, when refurbishing to a new fence by using the existing fence post as it is, it is desired to easily and reliably fix the new fence fence main body to the existing post via a joint fitting.

  However, a fixing structure for the upper part of the fence main body for a new fence that satisfies such a request has not been proposed at present.

  On the other hand, mesh fences, which are gaining popularity due to their superior aesthetics compared to net fences using rhombus wire mesh 3, are becoming mainstream in recent years. The mesh fence is constructed as a fence panel by welding a steel wire horizontal beam to a steel wire vertical beam formed by bending the upper and lower ends into various shapes and forming a trunk edge, and forming a fence panel. Thereafter, this panel is coated with a resin.

  Therefore, the purpose of the present invention is to use the upper fence fitting fixed to the upper trunk edge of the new fence main body when refurbishing the existing fence into the new fence, using the existing fence post made of hat-shaped steel as it is. An object of the present invention is to provide a fixing structure between an existing support column and an upper joint metal fitting that can be fixed to an existing support column with a single touch.
