Description

  The present invention relates to a pile for firmly fixing a wire mesh to the ground.

  In areas where many wild animals live, they are exposed to various harms caused by wild animals descending from the mountains. For example, wild animals that have invaded the farmland have damaged their crops, trees have suffered damage, or have collided with wild animals that have jumped out on roads and tracks. Exterminating all these wild animals is not realistic. In order to prevent coexistence with wild animals, partition walls and wire netting are provided to prevent wild animals from passing through, separating wild animal habitats from human activity areas and surrounding farmland. Yes.

  However, providing a partition wall made of concrete or a metal plate is expensive and time-consuming, so in many cases, the above-mentioned coexistence of isolation is achieved by extending a wire mesh. For example, as described in Patent Document 1, a highly durable and flexible wire mesh such as a turtle shell wire mesh is often provided between struts ("pile" in the document) driven at intervals. This is because wild animals often rush into the wire mesh, so that the wire mesh lasts longer and the wild animals are not hurt as much as possible.

  However, the rush due to adults of deer and sharks is strong, and there is a risk that the wire mesh will be turned or peeled off even if the support and the wire mesh are firmly installed. When a spear or deer rushes, the lower part of the wire mesh that has received it is pulled away from the ground, creating a gap, which can lead to intrusion.

  Therefore, in order to prevent a gap from being formed in the lower part of the wire mesh, a pile that fixes the lower part of the wire mesh in addition to the support is driven. Various shapes of this pile have been proposed, and it is almost common to have a hook portion for fixing the wire mesh and a return plate for making it difficult to come off the ground. For example, the anchor pin described in FIG. 11 and [0030] of Patent Document 2 can be given.

  The shape of the wire mesh fixing pile 11 disclosed as the anchor pin is shown in a perspective view of FIG. 6A, a front view of FIG. 6B, a side view of FIG. 6C, and a bottom view of FIG. The upper side tip end 13 of about a quarter of the upper part of the round pile 12 made of metal is bent 135 degrees or more and is directed obliquely downward. The bent part is a hooking part 14 for hooking the lower part of the wire mesh. A triangular metal plate serving as a return plate 17 that is difficult to come out after being stabbed into the soil is welded to the side surface in the vicinity of the lower tip 16 that is the lower tip of the support column 15 below the hook 14. . The metal plate of the return plate 17 is welded (20) so as to align with a plane virtually formed by the support column portion 15 and the upper end portion 13. 6C when viewed from the side, and FIG. 6D when viewed from directly below. By aligning the direction of the upper tip portion 13 and the flat surface of the support column 15 in this way, the occupied area for storing can be made thin, so that it is not bulky when it is brought into the field where a large number must be driven.

  The example of the condition which fixes a metal mesh with this pile 11 for metal mesh fixation is shown to Fig.7 (a) (b). A plurality of wire mesh fixing piles 11 and 11 are driven into the bottom latitude line 23 at the lower end portion of the wire mesh strung between the struts 21 and 21 driven into the ground and in contact with the ground. The bottom latitude line 23 may be aligned where it touches the ground, but in order to make it difficult to turn, a part of it is laid on the ground as shown in FIG. 7B, and the tip is fixed with the wire mesh fixing pile 11 There is also. FIG. 8 shows the positional relationship seen from above when the hooking portion 14 of the wire mesh fixing pile 11 is hooked on the bottom latitude line 23 of the wire mesh and driven into the ground.

  However, when the wire mesh fixing pile 11 is driven into the ground as shown in FIG. 8, since the insertable width L is narrow and the triangular return plate 17 is in a positional relationship that easily interferes with the bottom wetting line 23 of the wire mesh, the column portion 15 The positioning for driving the tip of the arm requires a certain degree of precision. For example, it is necessary to devise an arrangement such as inclining as in the driving example of FIG. For this reason, when it was necessary to drive a large number of piles, it took some time to ensure positioning.

  In view of this, an object of the present invention is to increase the efficiency of the work of fixing the wire mesh to the ground by making it difficult to interfere with the wire mesh and making the pile easier to drive when firmly fixing the wire mesh to the ground.

This invention relates to a pile for fixing a wire mesh having a hook part having a structure in which one side which is an upper side tip part of a pile having a rod shape is folded,
On the lower side tip of the other side, the other tip side is pointed and has a flat plate-like return plate having a return part on the opposite side, along the length direction of the pile,
Positioning of the return plate with respect to the folding direction as the upper side tip portion, a positional relationship in which a virtual plane formed by the tip side of the pile and the column portion that is not folded and the return plate are orthogonal to each other By doing so, the above-mentioned problems have been solved.

  The present invention is effective when the lower end portion of a wire net mainly used for animal protection is firmly fixed to the ground. The wire mesh fixing pile according to the present invention is driven into the ground with the wire mesh wire and the return plate aligned in parallel. If this is done, there is a margin in the width for hooking the hook portion on the latitude line of the lower end portion of the wire mesh, and the accuracy of the position required for the driving operation is lowered. Thereby, since the driving operation can be advanced more quickly than before, the lower part of the wire mesh can be fixed more efficiently than before.

  The wire mesh fixing pile according to the present invention can improve the efficiency of the work of fixing the wire mesh to the ground. It becomes easy to fix the wire net for animal protection firmly on the ground, and many piles can be driven quickly. The work efficiency is improved, and the number of driving can be increased and the work can be more firmly fixed to the ground.

  Hereinafter, embodiments of the present invention will be described in detail. The present invention is a wire mesh fixing pile for firmly fixing the lower end side of a wire mesh to the ground, and a wire mesh fixing method using the same.

  An embodiment of a wire mesh fixing pile 1 according to the present invention is shown in FIGS. 1A is a perspective view, FIG. 1B is a front view, and FIG. 1C is a side view. This wire mesh fixing pile 1 is composed of a round pile 2 having a columnar shape and a bent portion in the middle, and a return plate 7 having a pointed end portion 8 that is easy to pierce and a return portion 9 that is prevented from coming off. Both the round pile 2 and the return plate 7 are preferably made of metal, and are preferably made of stainless steel resistant to rust because they are embedded in the soil. From the point of rust resistance, it may be made of a strong resin, but from the viewpoint of durability and strength, those made of chromium-plated iron or stainless steel are preferable. In the case of resin, it can be integrally formed, but in the case of metal, the round pile 2 and the return plate 7 may be joined by welding (20).

  The round pile 2 has the support | pillar part 5 which should be stabbed as a pile, and has the part bent so that it might turn to diagonally downward or the downward direction in about 1/5 to 1/3 of the whole from the upper side. The tip of the side shorter than the bent portion is referred to as the upper tip 3. The side that is longer than the bent portion is a portion that is mainly embedded in the soil as the support column 5. The other side is referred to as a lower end portion 6.

  On the other hand, since the bent portion is a portion to be hooked and fixed as a hooking portion 4 on the wire rod at the lower part of the wire mesh, the support portion 5 and the upper side tip portion 3 are arranged so that the wire mesh does not come off even if it receives an impact. It should be bent at an angle of 135 degrees or more. There is no particular problem as long as the angle is larger than that, and it may be 180 degrees. However, in order to arrange the iron wire constituting the wire mesh inside the bent portion, the curvature radius r inside the hook portion 4 is preferably about 3 mm or more and 1 cm or less.

  Although the diameter of the round pile 2 is not specifically limited, it is easy to utilize that it is about 5 mm or more and 15 mm or less in diameter in general. Further, the length (full length) from the lower tip 6 of the round pile 2 to the upper tip 3 along the curve of the hooking portion 4 is not particularly limited, but it is generally easily driven when it is 30 cm or more and 100 cm or less. . Although the length from the hook part 4 to the upper side front-end | tip part 3 is not specifically limited, it is easy to hook a metal mesh as it is 10 cm or more and 20 cm or less.

  Moreover, when the front-end | tip of the lower side front-end | tip part 6 of the round pile 2 is sharp in the shape of a pyramid or a cone, it is easy to drive in and it is preferable.

  A return plate 7 made of an isosceles triangular plate pointed downward along the support column 5 is attached to the round pile 2 in the vicinity of the lower end portion 6. It is easy to stab into the ground because the lower tip 8 has an acute angle smaller than 45 degrees. On the other hand, the return portions 9, 9 consisting of the other upper two corners are larger than 45 degrees, and after being pierced into the ground, it has the effect of being caught by the soil and not easily coming out. The return plate 7 is preferably a triangle from the viewpoint of manufacturing, but may be deformed like a square having a recess from the return portions 9 and 9 toward the center in order to enhance the return effect. In any form, the lower point is a flat plate that is sharp and easy to stab, and the upper side is a stopper.

  The wire mesh fixing pile 1 according to the present invention is driven into the ground by hooking the wire with the hooking portion 4 in order to fix the wire under the wire mesh to the ground. This embodiment is shown in the front view of FIG. 2A and the side sectional view of FIG. In this figure, a wire mesh composed of lattice-like latitude lines 22 and meridians 24 is taken as an example, but the form of the wire mesh is not limited to this, and a turtle shell wire mesh or the like may be used. In either case, the hook 4 is hooked on the lower hooked portion.

  When the wire mesh fixing method using the wire mesh fixing pile 1 is carried out, that is, when the pile is driven, the return plate 7 is arranged such that the upper end portion 3 and the support column portion 5 bent by the hook portion 4 It becomes arrangement | positioning orthogonal to the virtual plane H formed by these. FIG. 3 shows the positional relationship and the arrangement of the wire mesh wire rod when driven into the ground. This figure is the figure which looked at the hook part 4 from the top, and is a conceptual diagram of the viewpoint of the operator who tries to hit the hook part 4 with a hammer when driving. In the figure, a bottom latitude line 23 which is a latitude line at the lower end portion of the wire mesh crosses to the left and right in the figure. The triangular return plate 7 is parallel to the bottom latitude line 23 at the lower end portion of the wire mesh, and the virtual plane H is orthogonal to the bottom latitude line 23. Positional relationship. That is, the hooking portion 4 can be hooked on the bottom latitude line 23 without the return plate 7 interfering with the bottom latitude line 23.

  4A and 4B are cross-sectional views including the underground in a state where the wire mesh fixing pile 1 is driven into the underground. FIG. 4 (a) shows a case where the tip of the wire mesh is extended and placed on the ground, and FIG. 4 (b) shows a case where the wire mesh is fastened between the columns. That is, in FIG. 4A, the portion ahead of the bottom latitude line 23 at the bottom between the columns 21 extends so as to reach the ground, and the extension latitude line 25 at the tip is fixed to the ground. . On the other hand, in FIG. 4 (b), the bottom latitude line 23 at the lowermost part between the columns 21 is the end of the wire mesh, and this bottom latitude line 23 is fixed to the ground. In any case, as shown in FIG. 3, the return plate 7 is driven without interfering with the extended portion latitude line 25 or the bottom portion latitude line 23.

  Even in the case of not only the lattice-like wire mesh composed of latitudes and meridians but also the turtle shell wire mesh or the like, the wire mesh fixing pile 1 may be driven by arranging the return plates 7 in parallel to the wire constituting the wire mesh.

  Furthermore, when the bottom latitude line 23 between the columns 21 is the end of the wire mesh, an embodiment in which an additional laying wire mesh 26 is provided adjacent to the wire mesh to further increase the anti-beast effect is shown in FIG. Shown in b). As the additional laying wire mesh 26, it is assumed that a lattice type wire mesh composed of laying latitude lines 27 and laying meridians 30 is laid. The laying end latitude line 29 at one end of the laying latitude line is arranged adjacent to the bottom latitude line 23 of the erected wire mesh. Then, the laying end latitude line 29 and the bottom latitude line 23 are collectively hooked and fixed to the hooking portion 4 of one wire mesh fixing pile 1. Further, the wire mesh fixing pile 1 is also driven and fixed separately for the laying end latitude line 28 at the other end of the additional laying wire mesh 26. Thereby, also about the wire mesh which did not have a laying part, it connects with the part laid and fixed, and can improve a beast-proof effect.
