As a result, the two reticulates connected side by side are integrally connected by the reticulated body connecting tool in such a state that their respective end portions are overlapped in the front and rear with the struts interposed therebetween.

  In the above-described configuration of the present invention, for example, an iron wire is used as the vertical and horizontal wires constituting the net-like body, and the support is configured using a rod-shaped steel material or the like. The longitudinal wire and the transverse wire may have the same diameter, or may have different diameters.

  In a preferred embodiment of the present invention, the nets are arranged at intervals at which the vertical wire rods cannot pass through the target harmful animal, and the horizontal wire rods are at least on the upper end side and the lower end side, respectively. It is arranged two by two, and the lowest horizontal wire on the upper end side is arranged at a height where the target pest will not reach the uppermost horizontal wire on the lower end side. Has been.

  According to this embodiment, since the vertical wire rods are arranged at intervals at which the target pests (for example, wild boars) cannot pass through, the pests cannot pass through the gaps of the reticulate body. Further, at least two horizontal wires are arranged on each of the upper end side and the lower end side, and the lowest horizontal wire on the upper end side is compared to the uppermost horizontal wire on the lower end side. Since the target pest is placed at a height that cannot be reached, even if the pest climbs onto the uppermost horizontal wire on the lower end side, the lowest position on the upper end side from that position The horizontal wire cannot be reached and the net cannot be overcome. Moreover, since at least two horizontal wires are arranged on each of the upper end side and the lower end side, all the vertical wires are firmly connected at the upper end portion and the lower end portion, so that The strength is increased, the deformation of the mesh body can be prevented, and there is no possibility of the mesh body being pierced by a harmful animal.

  If this invention is prescribed | regulated from another viewpoint, this invention concerns on the mesh body connection body for assembling said fence assembly. That is, the fence assembly network connector according to the present invention has two continuous meshes, each of which has a plurality of wires crossed vertically and laterally and to which the crossing portion is fixed, and each end is overlapped in front and back with a post interposed therebetween. A pair of opposed vertical plate portions formed integrally, and between each vertical plate portion, the vertical direction before and after the overlapping end portion of each mesh member is provided. A wire rod insertion groove having a groove width into which the wire rod and a support interposed between the wire rods can be inserted is formed. At the same position of the lower end edge of each vertical plate portion, two notches having a groove width that can be inserted through the horizontal wires crossing the front and rear longitudinal wires inserted into the wire insertion grooves. The grooves are arranged side by side.

FIG. 1 shows a schematic configuration of a fence assembly according to an embodiment of the present invention. In addition, although the thing of the example of illustration is used for a beast harm protection fence, the fence assembly of this invention is applicable also to fences other than a beast harm protection fence.
The fence assembly 1 in the illustrated example is vertically arranged on the ground, and a plurality of mesh bodies 2 and 2 that are successively arranged side by side, and a column 3 that is vertically arranged on the ground at each position where the mesh bodies 2 are joined. The reticulate bodies 2 and 2 are composed of reticulated body couplers 4 and 4 for integrally connecting the reticulated bodies 2 and 2 to the support column 3.
As shown in FIG. 3, the adjacent mesh bodies 2 and 2 are overlapped with the inner end portions 2 </ b> L and 2 </ b> R connected to each other with a slight positional shift. At least one reticulate body connector 4 is disposed at each of the upper and lower positions, and reticulate bodies 2 and 2 are connected in a state where they are overlapped in the front and rear with the support 3 interposed therebetween.

As shown in FIG. 2, each mesh body 2 has a plurality of wire rods 20 and 21 crossing vertically and horizontally in substantially the same plane, and all the crossing portions are integrally fixed by welding. Hereinafter, the vertical wire 20 is referred to as “vertical wire 20”, and the horizontal wire 21 is referred to as “horizontal wire 21”. As shown in FIGS. 3 and 4, the mesh bodies 2 and 2 to be coupled are coupled with a slight positional shift in the front and rear directions, but the vertical wire 20 of each mesh body 2 has a mesh shape of the horizontal wire 21 and the counterpart. Crossing with the body 2 on the opposite side.
In the network 2 of the illustrated example, iron wires having a circular cross section with a diameter r of 5 mm are used as the vertical wires 20 and the horizontal wires 21. In this embodiment, the length of the vertical wire 20 is 1 m and the length of the horizontal wire 21 is 2 m. However, the diameter and length of the iron wire are not limited thereto.
The vertical wires 20 are provided at intervals at which the harmful animal cannot pass through. In this embodiment, a wild boar is assumed as a harmful animal, and the arrangement interval t of the vertical wires 20 is set to 75 mm so that a Weifang (wild boar child) cannot pass through.

  The horizontal wire 21 is disposed on the upper end side and the lower end side with a region S in the center of the height. In this embodiment, the number of the upper end side is set to two, and the number of the lower end side is set to three. By arranging at least two each on the upper end side and the lower end side, all the vertical wires 20 are firmly connected at the upper end portion and the lower end portion, so that the overall strength of the mesh body 2 is increased, deformation, etc. Is prevented.

The two horizontal wires 21 on the upper end side have a distance d1 between the upper end of the vertical wire 20 and the upper horizontal wire 21a of 50 mm, and the distance between the upper horizontal wire 21a and the lower horizontal wire 21b. (Interval) d2 is set to 75 mm.
The three horizontal wires 21 on the lower end side have a distance d5 between the lower end of the vertical wire 20 and the lowest horizontal wire 21e of 65 mm, and a distance d4 between the lowest horizontal wire 21e and the horizontal wire 21d at the intermediate position is 150 mm. The distance d3 between the horizontal wire 21d at the intermediate position and the uppermost horizontal wire 21c is set to 75 mm.

  As shown in FIG. 1, each mesh body 2 is vertically arranged so that the lowest horizontal wire 21 e is located in the ground near the ground surface F. Since the lowest horizontal wire 21e is located in the ground near the ground surface F, it becomes an obstacle for the wild boar to dig up the soil, and can be prevented from passing through the lower side of the net 2. The distance d4 between the lowest horizontal wire 21e and the horizontal wire 21d above it is assumed that the lowest horizontal wire 21e is buried in the ground, and the horizontal wire 21d at the intermediate position and the horizontal wire 21c above it. Is set to be larger than the distance d3.

  The height h of the horizontal wire 21b on the lower side on the upper end side with respect to the uppermost horizontal wire 21c on the lower end side is such that, even if a wild boar rides on the horizontal wire 21c with the rear foot, the rear foot does not reach the horizontal wire 21b. Such height is set to 660 mm in this embodiment. Thus, since there is no horizontal wire that serves as a foothold in the region S in the center of the height between the uppermost horizontal wire 21c on the lower end side and the lower horizontal wire 21b on the upper end side, the boar is reticulated. It is impossible to get over body 2.

  The support column 3 is driven vertically into the ground with the lower end driven deeply into the ground, and it is desirable to sharpen the lower end so that it can be driven into the ground and is easy. Since the support column 3 is driven deeper than the mesh body 2, the length is set to be larger than the height of the mesh body 2 so that the height is substantially aligned with the mesh body 2 when vertically installed. A steel rod having a diameter R of 10 to 13 mm is used for the column 3 of this embodiment, and a spiral strip (not shown) may be formed on the outer peripheral surface in order to make it difficult to escape from the ground.

  As shown in FIGS. 3, 4, and 6, the net-like body connector 4 is formed by bending and folding a rectangular rectangular metal plate material at a right angle at the center of the length, and a pair of opposing vertical plate portions. 41 and 42 and the bent plate part 40 are integrally provided. In this embodiment, a galvanized steel plate is used as the metal plate material, but the present invention is not limited to this. A space surrounded by the vertical plate portions 41 and 42 and the bent plate portion 40 constitutes a wire rod insertion groove 5 into which the support column 3 and the two vertical wire rods 20 and 20 can be inserted. The wire insertion groove 5 is released in each of the up and down directions and one of the front and rear directions, that is, the opposite side of the bent plate portion 40.

  The wire rod insertion groove 5 includes a vertical wire rod 20L at the inner end 2L of one mesh body 2 (front mesh body 2 in FIG. 3) to be connected and the other mesh body 2 (back mesh body in FIG. 3). The groove width w in which the vertical wire 20R of the inner end 2R of 2) and the column 3 sandwiched between the two vertical wires 20L and 20R can be inserted, that is, w> R is set.

  In addition, the wire insertion groove 5 has an intersecting portion between the vertical wire 20L and the horizontal wire 21 of the front mesh body 2 and an intersecting portion between the vertical wire 20R and the horizontal wire 21 of the back mesh 2 inside. Is set to a groove depth y in which the support column 3, the two vertical wires 20L and 20R, and the two horizontal wires 21 and 21 are accommodated, that is, y> R + 2r, and As shown in FIG. 5 to FIG. 7, at the same position of the lower edge of each vertical plate portion 41, 42 so that the horizontal wire 21 passes through each vertical plate portion 41, 42 across the wire insertion groove 5, Two notch grooves 43 and 44 having a groove width u through which the horizontal wire members 21 and 21 intersecting with the front and rear vertical wire members 20L and 20R passing through the insertion groove 5 in the vertical direction are formed into the diameter R of the column 3. Are opened at almost the same interval z.

  In this embodiment, the groove width u of each notch groove 43, 44 is set to a value slightly larger than the diameter r of the horizontal wire 21, and the groove depth v is set so that the horizontal wire 21 does not easily come out. A value sufficiently larger than the diameter r, for example, v = 3r is set. In addition, each of the cutout grooves 43 and 44 has the opening edges 43a and 44a widened to make it easier for the horizontal wire 21 to enter, while the protrusions 45 and 46 are formed on one groove side edge to form the bottom of the cutout grooves 43 and 44. The horizontal wire 21 that has entered until is caught by the protrusions 45 and 46, making it difficult to come off.

  The fence assembly 1 having the above-described configuration is configured by sequentially connecting a plurality of mesh bodies 2 side by side. First, in order to assemble the fence assembly 1, the support pillars 3 are installed in the ground corresponding to positions where the mesh bodies 2 are connected side by side. Set up vertically. Next, after positioning the two mesh bodies 2, 2 connected side by side in a state where the inner end portions 2 </ b> L, 2 </ b> R overlap each other with the support 3 interposed therebetween, each mesh body 2 is connected by the mesh body connector 4. , 2 are connected to the support column 3 integrally. In the illustrated example, the mesh body connector 4 is installed at the position of the upper horizontal wire 21a on the upper end side and at the position of the uppermost horizontal wire 21c on the lower end side. You may install the mesh body coupling tool 4 also in the position of 21b and the position of the other horizontal wire 21d of a lower end side.

  The connecting work by the mesh body connector 4 is performed, for example, on the upper end side above the horizontal wire 21a, the vertical wire 20L before and after the inner end portions 2L and 2R where the mesh bodies 2 and 2 are superimposed on the wire rod insertion groove 5. , 20R and the vertical wire rods 20L, 20R are inserted into the wire rod insertion groove 5 by fitting the mesh member connector 4 so as to be inserted between the vertical wire members 20L, 20R and then inserting the mesh member connector 4 downward. The horizontal wires 21 and 21 crossing the front and rear vertical wires 20L and 20R are inserted into the two cutout grooves 43 and 44 provided in the vertical plate portions 41 and 42, respectively. As a result, the two mesh bodies 2, 2 connected side by side are integrally connected by the mesh body connector 4 with the inner end portions 2 </ b> L, 2 </ b> R overlapped with each other with the support 3 interposed therebetween.

  When the fence assembly 1 is constructed in this way, the vertical wires 20 are arranged at intervals t at which the target harmful animal (for example, wild boar) cannot pass through. Can't go through. In addition, at least two horizontal wires 21 are arranged on each of the upper end side and the lower end side, and the lowest horizontal wire 21b on the upper end side is the target with respect to the uppermost horizontal wire 21c on the lower end side. Since the pests are disposed at a height that cannot be reached by the pests, even if the pests ride on the uppermost horizontal wire 21c on the lower end side, the lowermost horizontal wire 21b on the upper end side from that position. The foot cannot reach the foot and the foot or the toenails cannot be hooked, so the net 2 cannot be overcome. Moreover, since at least two horizontal wires 21 are arranged on each of the upper end side and the lower end side, all the vertical wires 20 are firmly connected at the upper end portion and the lower end portion, and the overall strength of the net-like body 2 is increased. The deformation of the reticulate body 2 can be prevented, and there is no possibility that the reticulate body 2 is broken through by a harmful animal.

  In addition, although said Example is a beast harm protection fence for the boars, Comprising: Although the thing of the structure shown in FIG. 2 is used as the mesh body 2, it differs from this according to the target beast Can be used. Further, in applications other than beast harm protection, for example, various forms such as arranging the vertical wire 20 and the horizontal wire 21 at the same interval can be adopted.
