Description

  The present invention relates to a fence trunk and a fence, in particular, a fence trunk which can be formed easily and in a short period of time, and by using this trunk, it is easily constructed in a short period of time and at a low cost. It can be related to a fence.

  2. Description of the Related Art A wire mesh fence is known in which a rhombus wire mesh is attached between upper and lower ends of a pillar having a cross-sectional shape of a hat shape. The trunk edge is attached to the rhombus metal mesh by hooking an iron wire inserted through the end of the knuckle-shaped rhombus metal mesh onto a claw formed in a vertical portion of the trunk edge.

  The vertical portion of the trunk edge is inserted into a claw formed in the lip portion of the support column, and the horizontal portion of the trunk edge is fixed to the support column via a fixing bracket by a bolt inserted into the peak portion of the support column.

  The wire mesh fence described above is widespread due to its simple structure and the like, but the diamond wire mesh is formed in the vertical part of the trunk edge with the iron wire inserted through its end as described above. Since it was attached to the trunk edge by hooking it on the nail, there was a problem that it was easily detached from the trunk edge.

  A wire mesh fence designed to solve this problem is disclosed in Patent Document 1.

  Hereinafter, this wire mesh fence is referred to as a conventional fence A and will be described with reference to the drawings.

  4 is a front view showing a method for assembling the fence body of the conventional fence A, and FIG. 5 is a partially omitted sectional view showing the fence body of the conventional fence A.

  As shown in FIGS. 4 and 5, the conventional fence A is composed of a fence body 11 attached between columns (not shown). The fence body 11 is composed of a rhombus wire mesh 12 having a knuckle process on an end portion 12 a and a trunk edge 13. The trunk edge 13 includes a spiral wire 14 attached to the end 12a of the rhombus metal mesh 12, and a pipe 15 into which the spiral wire 14 is inserted and in which a slit 15a is formed over the entire length.

  For the knuckle processing, for example, as shown by a solid line in FIG. 4, a horizontal knuckle processing in which the end 12 a of the rhombus metal mesh 12 is bent horizontally, and as shown by a dotted line in FIG. There are a complete knuckle process in which 12a is completely bent and a curl process in which the end of a rhombus metal mesh is bent in a ring shape, as will be described later. Since it takes time to curl, a wire mesh subjected to curl processing is more expensive than a wire mesh subjected to horizontal knuckle processing or complete knuckle processing. In this respect, the conventional fence A is advantageous in terms of cost.

  To assemble the fence body 11, the tip of the spiral wire 14 is inserted into the end 12a of the rhombus metal mesh 12, and the spiral wire 14 is fed while rotating around its axis. Thus, when the spiral wire 14 is attached over the entire length of the end 12a of the rhombus metal mesh 12, the spiral wire 14 is inserted into the slit 15a from one end of the pipe 15. In this way, the fence body 11 is assembled.

  FIG. 6 is a partially omitted sectional view showing a fence body in another wire mesh fence (hereinafter referred to as a conventional fence B).

  As shown in FIG. 6, the conventional fence B consists of the fence main body 16 attached between columns (not shown). The fence body 16 is composed of a rhombus wire mesh 17 and a trunk edge 18 whose end portions 17 a are curled. The trunk edge 18 is formed by inserting an end portion 17 a of a rhombus metal mesh 17 that has been subjected to curling into a pipe 19. A slit 19 a is formed in the pipe 19 over its entire length. To assemble the fence body 16, the end 17 a of the rhombus metal mesh 17 is inserted into the slit 19 a from one end of the pipe 19.

  FIG. 7 is a partially omitted front view showing still another wire mesh fence (hereinafter referred to as a conventional fence C).

  As shown in FIG. 7, the conventional fence C is configured by attaching a fence body 20 to a column 21. The fence body 20 includes a trunk edge 23 formed of a pipe fixed to a support column 21 by a U bolt 22 and a rhombus wire mesh 24. The trunk edge 23 and the rhombus metal mesh 24 are connected via a suspension band 25 attached between the trunk edge 23 and the iron wire 26 inserted through the rhombus metal mesh 24.

JP 2006-283495 A

  According to the conventional fences A to C, it is possible to prevent the rhombus wire mesh from coming off from the trunk edge, but there are the following problems.

  According to the conventional fence A, in order to assemble the fence main body 11, the step of inserting the tip end of the spiral wire 14 into the end portion 12 a of the rhombus metal mesh 12 and feeding the spiral wire 14 while rotating it around its axis; Since it is necessary to insert the spiral wire 14 into the pipe 15 from one end, it takes time and labor to assemble the fence body 11. In addition, since the width of the slit 15a formed in the pipe 15 is narrow, it takes time and labor to insert the spiral wire 14.

  According to the conventional fence B, it is difficult to insert the end 17a of the rhombus metal mesh 17 subjected to curling into the slit 19a of the pipe 19. In addition, as described above, the wire mesh that has been subjected to curling has a higher cost because it takes more time to knuckle processing than a wire mesh that has been subjected to horizontal or complete knuckle.

  An embodiment of the fence of the present invention will be described with reference to the drawings.

  FIG. 1 is a partial front view showing a fence main body in the fence of the present invention, and FIG. 2 is a partial front view showing an assembling method of the fence main body in the fence of the present invention.

  In FIG. 1 and FIG. 2, 1 is a fence main body in the fence of this invention. The fence body 1 is composed of a rhombus metal mesh 2 as a net body and a trunk edge 3 formed on an end portion 2a on which the knuckle processing of the rhombus metal mesh 2 is performed. In addition to the rhombus metal mesh 2, the net body may be a grid metal net obtained by welding steel wires in a lattice shape, an expanded metal, or a resin net obtained by knitting a resin string in a rhombus shape or a lattice shape. The trunk edge 3 is composed of a spiral wire 4 attached to the end 2 a of the rhombus wire mesh 2 and a steel pipe 5 as a trunk edge member inserted into the spiral wire 4. In addition to the pipe 5, the body edge material may be a steel material such as angle steel. A complete knuckle process is applied to the end 2 a of the rhombus wire mesh 2. It may be a diamond wire mesh that has been subjected to horizontal knuckle processing. The diameter of the spiral wire 4 is formed larger than the diameter of the pipe 5.

  In order to form the trunk edge 3, as shown in FIG. 2, the pipe 5 is arranged along the end 2a of the rhombus metal mesh 2, the tip of the spiral wire 4 is inserted into the end 2a of the rhombus metal mesh 2, and the spiral The wire 4 is rotated around its axis and fed along the pipe 5. Thereby, the trunk edge 3 which consists of what the pipe 5 was attached to the edge part 2a of the rhombus metal-mesh 2 via the spiral wire 4 is formed.

  Thus, since the pipe 5 and the diamond wire mesh 2 are connected by the spiral wire 4, the diamond wire mesh 2 is not detached from the pipe 5, and the tip of the spiral wire 4 is connected to the end 2 a of the diamond wire mesh 2. Since the trunk edge 3 can be formed only by inserting and feeding the spiral wire 4 while rotating it about its axis, the trunk edge 3 can be formed more easily than the conventional fence described above.

  The trunk edge 3 according to the present invention first inserts the tip of the spiral wire 4 into the end 2 a of the rhombus metal mesh 2 and feeds the spiral wire 4 while rotating it around the axis. Thereafter, the pipe 5 is inserted into the spiral wire 4. You may form by inserting.

  The above-described trunk edge 3 of the present invention is formed on the end 2a of the rhombus metal mesh 2 which has been knuckle processed. However, as shown in FIG. 3, the knuckle processing of the rhombus metal mesh 2 is performed. It can also be formed at the end 2b on the non-side. The forming method is the same as that for forming the end 2a of the rhombus wire net 2 subjected to knuckle processing.

  In order to construct a wire mesh fence using the trunk edge 3 of the present invention, the fence body is constructed by forming the trunk edge of the present invention on the upper, lower, left and right ends of the rhombus metal mesh 2, and the fence body is placed between the columns It may be attached, or the trunk edges of the left and right ends of the rhombus metal mesh 2 may be known trunk edges.

In the above, the spiral wire 4 is inserted into the end 2a of the rhombus metal mesh 2, and the pipe 5 and the rhombus metal mesh 2 are connected to form the body edge 3. In the present invention , the two in FIG. As shown by the dotted line, the iron wire 6 is inserted into the end 2 a of the rhombus metal mesh 2, and the pipe 5 and the rhombus metal mesh 2 are connected via the iron wire 6 by the spiral wire 4 to form the body edge 3 . As a result, the pipe 5 and the diamond wire mesh 2 can be connected even when the mesh size of the diamond wire mesh 2 does not match the pitch of the spiral wire 4.

  Further, if the iron wire 6 is inserted, the spiral wire 4 having the same pitch can be used even if the diamond metal mesh 2 has a different mesh size.

As described above, according to the present invention, since the trunk rim is formed by attaching the trunk rim material to the end of the mesh body via the spiral wire and the iron wire , there is no possibility that the trunk rim is detached from the mesh body. In addition, it is possible to form the barrel edge only by inserting the tip of the spiral wire into the end of the mesh body and feeding it while rotating the spiral wire around its axis. Yes. Moreover, even if the size of the rhombus metal mesh does not match the pitch of the spiral wire, the pipe and the rhombus metal mesh can be connected. In addition, if an iron wire is inserted, spiral wires having the same pitch can be used even if the rhombus wire mesh has different dimensions. Furthermore, by using this body edge, when using a rhombus wire mesh as a mesh body, coupled with the effect of reducing the cost by eliminating the need to curl the end of the rhombus wire mesh, it is easy and short. Wire mesh fences can be constructed on time and at low cost.
