Description

  The present invention relates to a lattice body formed by arranging a plurality of lattice components in a lattice shape and a fence using the lattice body.

  A mesh fence combining a lattice body and a support column is used as a means for partitioning a boundary with a road, a boundary between sites, and the like. This grid body is generally a vertical wire and a horizontal wire used as a grid constituent material, the vertical wire and the horizontal wire are arranged in a grid, and the intersections are joined by welding. Further, the welded intersection is often subjected to a surface treatment with a synthetic resin. As a result, the corrosion resistance can be enhanced and the landscape can be enhanced, but the production process is complicated accordingly.

  Therefore, Patent Document 1 proposes a method of manufacturing a grid body using crosspieces as a grid constituent material. This manufacturing method arranges a plurality of crosspieces in an orthogonal shape and fixes the intersecting positions. The inner surface of the crosspiece arranged in one direction has a circular shape with a non-circular through hole extending from the inner surface, and a circular cross section is formed in the through hole. After the insertion, the crosspieces are fixed by pressing the raised portions of the crosspieces in which the through holes are formed.

JP-A-1-304281

  However, in the lattice body described in Patent Document 1, a crosspiece with a circular cross-section is continuously inserted into the circular through-holes of a large number of cross-pieces, and the crosspieces in which the through-holes are drilled are used. When the raised portion is pressed, it is necessary to fix the cross-shaped crosspiece, so that high accuracy is required for processing the through hole.

  The present invention solves the above-mentioned problems, uses a wire and a crosspiece as a grid component, and easily engages the wire and the crosspiece at the intersection of the lattice body composed of the wire and the crosspiece. It is intended to provide a lattice body that can be made and a fence using the lattice body.

In order to achieve the above object, the present invention is configured as follows.
That is, the lattice body according to the present invention is a lattice body composed of crosspieces and wires crossed in a lattice shape at intersections, and at each intersection, the wire is a long hole provided in the crosspieces. A flat portion that is penetrated by the through-hole and that extends on both sides across the through-hole is provided with a thin flat portion, and the wire is rotated about its longitudinal direction as a flat portion. The flat portion is allowed to pass through the through-hole in a state in which the spreading direction of the flat portion and the longitudinal direction of the through-hole are combined, and in the state in which the spreading direction of the flat portion and the longitudinal direction of the through-hole are orthogonal to each other, the flat portion Is not allowed to pass through the through hole, and the wire and the crosspiece are engaged at the intersection, and at the intersection where the wire and the crosspiece are engaged, both side surfaces of the through hole and the wire Is characterized in that it is made not to interfere .

  In the lattice according to the present invention, the wire rods at each intersection may be configured such that the crossing angle in the vertical direction with respect to the crosspieces can be changed.

In the grid according to the present invention, the flat portion may be formed by pressing a part of the wire.

  According to the grid according to the present invention, at each crossing portion, the wire is penetrated through a long through hole provided in the crosspiece, and is thinned at positions on both sides of the through hole. In the state in which the flat portion extending laterally is provided, and the wire is rotated about its longitudinal direction as the axis so that the spreading direction of the flat portion matches the longitudinal direction of the through hole, the flat portion penetrates. In a state in which the hole is allowed to pass and the spreading direction of the flat part is orthogonal to the longitudinal direction of the through hole, the flat part cannot pass through the through hole, and the wire and the crosspiece are engaged at the intersection. Therefore, when assembling the lattice body, first, align the spreading direction of the flat part of the wire with the longitudinal direction of the through hole of the crosspiece, and insert the through hole through the wire through the crosspiece of the crosspiece. The flat part is placed on the wire, and then the wire is rotated to make it flat. If the spreading direction and the longitudinal direction of the through-holes are orthogonal, the flat portion cannot pass through the through-holes at each intersection, and the wire and the crosspiece are engaged at the intersection. Easy assembly and disassembly of the body.

  In the grid according to the present invention, the wire rods at the respective intersections can change the grid shape of the grid even after the grid is assembled if the crossing angle in the vertical direction with respect to the crosspiece can be changed. It can be changed to a rectangular shape or a parallelogram shape.

  According to the fence according to the present invention, since the lattice body is supported between the columns that are erected at intervals on the installation surface, so as to follow the undulations of the installation surface when installing the fence. The lattice shape of the lattice can be changed to a rectangular shape, a parallelogram shape, or the like.

  Next, the best mode for carrying out the present invention will be specifically described with reference to the drawings.

  In the drawings, 1 is a support column, 2 is a lattice body supported by the support column 1, and the fence P according to the present invention is mainly composed of the support column 1 and the lattice body 2.

  FIG. 1 is an explanatory view showing a first embodiment of a fence P according to the present invention, and FIG. 1 is a schematic front view. The column 1 is generally a round pipe-shaped steel pipe that is stable in strength and low in cost, but may be a square pipe-shaped steel pipe, such as an H-shaped, T-shaped, or hat-shaped steel material. It may be a support made of. Further, it may be formed from other metals such as stainless alloy and aluminum alloy. The support column 1 is attached with a cap 11 on the upper end, and a plurality of the support columns 1 are provided at intervals.

  In the lattice body 2, a plurality of wires 3 extending in the horizontal direction are arranged at intervals in the vertical direction, and a plurality of crosspieces 4 extending in the vertical direction are arranged so as to cross the wires 3 at intervals in the horizontal direction. It is engaged at the intersection 21 and formed in a lattice shape. And the trunk edge 22 which covers the upper end part and lower end part of the crosspiece 4 is attached to the upper-lower-end part of the grid | lattice body 2, respectively.

  In this embodiment, the lattice body 2 is fixed to the support column 1 via the connecting member 5. In this embodiment, the connecting member 5 is arranged so as to fix the upper, middle, and lower steps of the end of the grid 2 to the column 1, but the grid 2 is interposed between adjacent columns 1. Any form that can be firmly fixed is acceptable.

  FIG. 1 shows a so-called fixed column type in which a grid 2 is arranged between columns 1 standing upright on an installation surface, and the grid 2 is fixed to the left and right sides of the column 1 via a connecting member 5. Although the fence P is shown, although not shown, the grid body is arranged on the front side or the rear side of the column, and the grid unit is fixed to the column via a fixing bracket such as a hook bolt attached to the column. The fence P according to the present invention may be configured by using the lattice body 2 according to the present embodiment in a so-called free column type fence.

  Next, the crossing portion 21 of the lattice 2 will be specifically described with reference to FIGS. First, in FIGS. 2 to 3, at each crossing portion 21 where the wire 3 and the crosspiece 4 constituting the lattice body 2 cross each other, the wire 3 includes a rod-like portion 31 extending along the longitudinal direction and both sides thereof. Two flat portions 32 which are thinner than the rod-shaped portion 31 and extend laterally are provided at intervals. On the other hand, the crosspiece 4 is formed with a through hole 41 having a substantially oval shape in side view, which penetrates in the left-right direction and is elongated in the up-down direction. And the rod-shaped part 31 of the wire 3 has penetrated the through-hole 41 of the crosspiece 4, and the said flat part 32 is arrange | positioned on both sides of the through-hole 41.

  In this embodiment, the rod-shaped portion 31 of the wire 3 is formed into a substantially circular cross-section of the shape of the wire 3 that is not processed at all, and is penetrated through the through hole 41 of the crosspiece 4. It can be rotated in the X direction or the Y direction with the longitudinal direction of the axis as the axis. Each of the two flat portions 32 has an expanded width H1 that is narrower than the longitudinal dimension K1 of the through-hole 41 and wider than a lateral dimension K2 orthogonal to the longitudinal direction. Yes. Thereby, if the expansion direction of the flat part 32 and the longitudinal direction of the through-hole 41 are matched, the flat part 32 can be penetrated through the through-hole 41, so that one flat part 32 is penetrated through the through-hole 41 and penetrated. Two flat portions 32 can be disposed on both sides of the hole 41. Then, if the wire 3 is rotated in the X direction or the Y direction so that the spreading direction of the flat portion 32 is in a direction perpendicular to the longitudinal direction of the through hole 41, the flat portion 32 cannot pass through the through hole 41. In the intersection part 21, it can be set as the state which the wire 3 and the crosspiece 4 engage, and cannot mutually remove | deviate. It should be noted that the spreading direction and the spreading width H1 of the two flat portions 32 do not have to be exactly the same, and may be different within a range that satisfies the above relationship.

  If the rod-shaped part 31 of the wire 3 has a circular cross section as in the present embodiment, it can be rotated in the X direction or the Y direction as long as it is penetrated through the through hole 41 of the crosspiece 4. However, as long as the flat portion 32 of the wire 3 can be changed between a state where it can pass through the through hole 41 and a state where it cannot pass, it is not shown, but for example, an elliptical cross section or a polygonal cross section may be used.

  The flat portion 32 of the wire 3 has a substantially oval shape in plan view in which the central portion is crushed so as to be wider than the diameter of the rod-like portion 31, but the wire 3 is rotated in the X direction or the Y direction. However, the shape of the flat portion 32 may be a disc shape, an elliptical shape, a polygonal shape, or the like in plan view, although not shown in the drawings. Further, the flat portion 32 may be able to pass through the through-hole 41 even when the spreading direction and the longitudinal direction of the through-hole 41 are deviated, and conversely, the spreading direction and the longitudinal direction of the through-hole 41 are different from each other. There may be a case where the through hole 41 cannot be passed even when not orthogonal.

  In this embodiment, the crosspiece 4 has a vertical plate portion 42 in which the through-holes 41 are provided at intervals in the vertical direction, that is, at each position where the wire 3 is located, and the vertical plate portion 42. The front plate portion 43 and the rear flange 44 provided at the front and rear are formed in a substantially H shape in plan view. If the crosspiece 4 is formed in a substantially H shape in plan view, the through hole 41 in the vertical plate portion 42 is formed. Since the thin-walled part in the vicinity where the is provided can be reinforced, it is preferable.

  Since the through-hole 41 of the crosspiece 4 is a long hole that is long in the vertical direction, the crossing angle of the wire 3 with respect to the crosspiece 4 can be changed as shown in FIG. That is, the through-hole 41 has an oval shape in which the center part of both side surfaces is substantially parallel to the vertical direction, and the rod-shaped part 31 penetrated through the through-hole 41 extends in the vertical direction (S direction or T direction in FIG. 9). Even if it is inclined, it is difficult to interfere with both side surfaces of the through-hole 41, and the crossing angle between the wire 3 and the crosspiece 4 can be changed in a wide range. Thereby, in each crossing part 21, since the crossing angle of the up-down direction of the wire 3 and the crosspiece 4 can be changed in a wide range, the shape of the lattice 2 is reversibly changed to a rectangular shape or a parallelogram shape. As shown in FIG. 1, the grid body 2 can be arranged in accordance with the undulations of the installation surface.

  Therefore, the shape of the through hole 41 may be any shape as long as it can secure a change range of the crossing angle where the wire 3 is required, and may be another shape such as an elliptical shape or a vertically long rectangular shape. In addition, the oval shape of the through hole 41 is preferable because the longitudinal direction is the vertical direction and the horizontal width of the vertical plate portion 42 of the crosspiece 4 is not unnecessarily widened. The longitudinal direction may be the other direction, and the other direction may be the longitudinal direction.

  The wire 3 is generally formed by crushing a part of a round wire from the front and the back by pressing to form a flat portion 32. Since the surface treatment layer such as galvanization applied to the surface remains, corrosion resistance, etc. It is preferable because performance degradation can be suppressed and the thickness of the flat portion 32 can be easily adjusted. Moreover, the cross-sectional shape of this wire 3 should just be substantially circular, and does not need to be a perfect circle. That is, in general, a steel wire is wound in a coil shape and is used by unwinding it, which may cause twisting and the like. For this reason, if the cross-sectional shape is a square shape or a hexagonal shape, if the press working is performed in a state where twisting occurs, the first flat portion 32 may be flattened or distorted. On the other hand, if the cross-sectional shape as in the present embodiment is substantially circular, the above-described flatness and distortion are less likely to occur, which is preferable.

  In this embodiment, the wire rod 3 is arranged in the horizontal direction, the crosspiece 4 is arranged in the vertical direction, and the wire rod 3 is supported by the crosspiece 4. In order to support the crosspiece 4, the wire 3 is arranged in the vertical direction, the crosspiece 4 is arranged in the horizontal direction to form the grid body 2, and the crosspieces 4 positioned at both side ends of the grid body 2 are supported It may be fixed to 1 and formed as a fence P.

  10 to 12 are partially enlarged front views showing a second embodiment according to the lattice body 2 of the present invention. Compared to the first embodiment, the shapes of the front flange portion 43 and the rear flange portion 44 of the crosspiece 4 are partially different, and the other forms are the same, so only the differences will be described. That is, the crosspiece 4 is formed with notches 45 and 46 from the front flange portion 43 and the rear flange portion 44 toward the vertical plate portion 42. A part of the flat portion 32 of the wire rod 3 is inserted into the cutout portions 45 and 46 so as to be locked. As a result, the flat portion 32 does not rotate carelessly, so that the engagement state between the wire 3 and the crosspiece 4 can be firmly maintained at the intersection 21.

  Since one wire 3 forms a crossing portion 21 with a large number of crosspieces 4, at least one crosspiece 4 out of the crosspieces 4 is provided with notches 45 and 46 and the flat portion 32 of the crosspiece 3. If the wire is locked, the wire 3 can be prevented from rotating carelessly.

  The notches 45 and 46 may be provided in advance before installation. However, if the installation surface is not substantially horizontal and has undulations as shown in FIG. Parts 45 and 46 may be provided. Thereby, even if the shape of the grid body 2 is changed to a parallelogram shape in accordance with the undulations of the installation surface, the engagement between the wire 3 and the crosspiece 4 can be firmly maintained, so that it is similar to the case shown in FIG. In addition, the lattice body 2 can be arranged according to the undulations of the installation surface.

  The lattice body 2 according to the present invention is configured such that a lattice constituent material is composed of a wire material and a crosspiece, and the wire is passed through a long through hole provided in the crosspiece so as to intersect in a lattice shape. Therefore, the assembly and disassembly of the grid body is easy, and in addition, if the crossing angle in the vertical direction of the wire 3 and the crosspiece 4 connected in a grid shape at the crossing portion can be changed, for example, For all uses, such as beast damage prevention fences installed around mountainous cultivated land to prevent the invasion of animals, and plant growth support fences planted along paths such as slopes, roads and sidewalks It can be suitably used as a fence.
