Description

  The present invention relates to a method for refurbishing an existing fence and a new fence, and more particularly, a method for refurbishing an existing fence and a new fence refurbished by this method, which can renovate an existing net fence into a mesh fence in a short time and at a low cost. It is about.

  There is a net fence as a fence that has been widely constructed. As shown in FIGS. 20 and 21, the net fence is composed of a support column 1 made of hat-shaped steel, an upper body made of angle steel, and a lower body edge 2 (only the upper body edge is shown) fixed between the support columns 1. 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 waist edge (not shown) to the rhombus metal mesh 3 is the same as that of the upper waist 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 net fence configured as described above, as time passes, the aesthetics are remarkably impaired due to the rust generated in the support column 1 and the torn and deformation of the rhombus wire mesh 3, and in some cases the function as a fence is lost. In some cases.

  It is best to reconstruct a fence having such a defect. However, since the construction cost and the construction period are high, it is advantageous to replace the damaged part with a new member. Even in the case of refurbishment, it is strongly desired to construct it at a lower cost in a shorter period of time.

  However, there has not been proposed a method for refurbishing existing fences that satisfies such demands 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.
