There is a method of wearing a sex sheet. According to this method, the vine plant tends to extend upward along the translucent sheet, but the vine plant cannot be entangled with the translucent sheet. Therefore, it is possible to prevent vine plants from getting over the fence and entering the site inside the fence. In addition, a sheet made of a flexible material can be carried in a rolled state, and can be attached to the fence while the roll is unfolded, making it easy to transport and install. .

  However, a translucent sheet made of nylon is corroded early by bacteria in the soil when it comes into contact with the ground. For this reason, the translucent sheet | seat which consists of nylon is mounted | worn with a fence in the state which left | separated the lower end part from the ground in many cases. In this case, there has been a problem that the vines invade from the gap between the translucent sheet and the ground, and the vines grow on the site. Also, if a translucent sheet made of nylon is attached to the fence in contact with the ground, the lower end of the translucent sheet will corrode early, and eventually vines will invade from the corroded area. There was a problem that.

  Patent Document 1 discloses a herbicidal sheet for preventing plants from growing on the road surface. However, this weedproof sheet is not a sheet for preventing vines from climbing on the fence.

(First embodiment)
Hereinafter, the sheet for preventing vine winding according to the first embodiment of the present invention will be described with reference to the drawings. 1A and 1B are views showing the appearance of a weed prevention sheet according to the first embodiment, wherein FIG. 1A is a front view showing a state in which the weir prevention sheet is attached to a fence, and FIG. (C) is a rear view showing the area indicated by arrow A in (a) in an enlarged manner, and (d) is a side view of the anti-wound sheet shown in (c). (E) is the rear view which expands and shows the area | region shown by the arrow B of (a), (f) is a side view of the anti-wound sheet | seat shown in (e). In FIG. 1B, the left side is the site outside the fence, and the right side is the site inside the fence.

  The vine winding prevention sheet 10 according to the first embodiment is a sheet attached to the fence 11 in order to prevent vine plants from climbing the fence 11.

  In addition, the fence 11 to which the anti-wound sheet 10 is attached includes, for example, a net provided around an undeveloped site, a site of concrete deterioration damage, a radio tower, a substation, a distribution station, a power transmission station, etc. There are fences, aluminum / stainless steel fences, lattice fences, mesh fences, etc.

  The vine winding prevention sheet 10 includes a light-shielding sheet 10b and a translucent sheet 10a.

  The light-shielding sheet 10b is a non-corrosive sheet attached to the fence 11 so as to stand up from the ground. The light shielding sheet 10b is made of a flexible material and can be wound. Although the raw material of the light-shielding sheet 10b will not be specifically limited if it has a softness | flexibility, For example, it can comprise with the nonwoven fabric which consists of a polyester fiber. When the light-shielding sheet 10b is composed of a nonwoven fabric made of polyester fiber, the nonwoven fabric is preferably a recycled product of a PET bottle. Moreover, the surface of the light-shielding sheet 10b has such flatness that vines cannot be entangled.

  The case where the light-shielding sheet 10b is comprised with a nonwoven fabric is demonstrated in detail. The light-shielding sheet 10b uses, for example, 100% polyester fiber, which is a recycled fiber of used PET bottles, and is a high-strength sheet subjected to 700 g of fiber usage per square meter and special baking processing. It is a so-called “Earth-friendly” product.

  In the recycling of PET bottles, the light-shielding sheet 10b is obtained by crushing and washing the collected waste PET bottles to remove foreign substances such as metal, and then obtaining polyethylene terephthalate material in the form of flakes and pellets. It is obtained by remanufacturing as a polyester fiber. Thus, since the light-shielding sheet 10b used for the anti-browsing sheet 10 is made of polyester, corrosion damage caused by bacteria from the soil can be prevented, and durability can be kept high.

  Moreover, since the light-shielding sheet 10b is excellent in water permeability, rainwater is drained naturally.

  Furthermore, since the light-shielding sheet 10b is braided with finer density, it has excellent weather resistance and durability (for example, using recycled fiber for 15 PET bottles per square meter, useful life of 10 years or more). Further, the light-shielding sheet 10b is excellent in chemical resistance and does not cause chemical changes in chemicals such as gasoline and light oil. Furthermore, since the light-shielding sheet 10b is made of polyester, it can be treated as household waste, and even if burned, there is no need to worry about environmental pollution such as dioxins.

  The light-shielding sheet 10b is configured in a strip shape extending in the lateral direction, and the height (band width) before installation is, for example, about 1000 mm. In addition, at the time of installation, the light-shielding sheet 10b is attached to the fence 11 in a bent state so that at least the lower end is grounded to the ground and rises upward from the midway. Therefore, at the time of installation, for example, the width of 500 mm is grounded and the width of 500 mm is raised (see FIG. 1B).

  A belt-like reinforcing sheet 10c that reinforces the light-shielding sheet 10b is attached to the back surface (surface facing the fence 11) of the light-shielding sheet 10b. The reinforcing sheet 10c extends in the horizontal direction, and one or more reinforcing sheets 10c are provided in the middle of the light shielding sheet 10b in the height direction. In the example shown in FIG. The upper side of the reinforcing sheet 10c is sewn to the back surface of the light-shielding sheet 10b, and the lower side is not sewn. A through-hole 12 for attaching the light-shielding sheet 10b to the fence 11 is formed at the lower end of the reinforcing sheet 10c. A reinforcing ring (not shown) for reinforcing the inner peripheral edge is attached to the inner peripheral edge of the through hole 12. Moreover, in the light-shielding sheet 10b, as shown in FIG. 1A, through holes 12 are formed in the left end portion and the right end portion thereof. A reinforcing ring (not shown) for reinforcing the inner peripheral edge is attached to the inner peripheral edge of the through hole 12. The light shielding sheet 10 b is attached to the fence 11 by connecting the through hole 12 and the mesh of the fence 11 with a connector. Although the kind of coupling tool is not specifically limited, For example, it is a wire.

  2A and 2B are diagrams showing components for fixing the lower end portion of the light-shielding sheet 10b to the ground. FIG. 2A is a plan view, a side view, and an end view showing the sheet terminal pressing member, and FIG. The figure which shows the fixed pile for concrete, (c) is a figure which shows the fixed pile for soil.

  As shown in FIG. 1B, the lower end of the light-shielding sheet 10b is pressed from above by a sheet terminal pressing member 13 in which a plurality of through holes 13a (see FIG. 2A) are formed. Then, the fixed pile 14 is driven into the ground from the through-hole 13a, thereby being fixed to the ground. The fixed pile 14 is either a concrete fixed pile 14 a used for the concrete ground 17 or a soil fixed pile 14 b used for the soil ground 18. The concrete fixed pile 14a is higher in strength and shorter than the soil fixed pile 14b.

  As shown in FIG. 1, the translucent sheet 10a is a sheet that is connected to the upper end of the light-shielding sheet 10b and is attached to the fence 11 above the light-shielding sheet 10b. The lower end portion of the translucent sheet 10a is wrapped with the upper end portion of the light shielding sheet 10b, and is sewn together in the wrapped state. The translucent sheet 10a is made of a flexible material and can be wound. The surface of the light-shielding sheet 10b has such flatness that vines cannot be entangled. Although the raw material of the translucent sheet | seat 10a will not be specifically limited if it has a softness | flexibility, For example, it can comprise from nylon or polyvinyl chloride. Since the translucent sheet 10a made of nylon or polyvinyl chloride has a self-lubricating property, entanglement of vines is further prevented. The translucent sheet 10a is configured in a strip shape extending in the lateral direction, and has a height (band width) of about 1000 mm, for example.

  A belt-shaped reinforcing sheet 10c that reinforces the translucent sheet 10a is attached to the back surface (the surface facing the fence 11) of the translucent sheet 10a (see FIGS. 1E and 1F). . The reinforcing sheet 10c extends in the lateral direction, and one or a plurality of reinforcing sheets 10c are provided in the middle of the translucent sheet 10a in the height direction. In the example shown in FIG. As shown in FIG. 1 (f), the reinforcing sheet 10 c has its upper side fixed to the back surface of the light-shielding sheet 10 b with an adhesive, and its lower side is not fixed. FIG. 1 (f) shows the lower side of the reinforcing sheet 10 c separated from the translucent sheet 10 a for convenience in order to show that the lower side of the reinforcing sheet 10 c is not fixed. The reinforcing sheet 10c attached to the translucent sheet 10a is the same as the reinforcing sheet 10c attached to the light-shielding sheet 10b. The translucent sheet 10 a is attached to the fence 11 by connecting the through hole 12 and the mesh of the fence 11 with a connector. Although the kind of coupling tool is not specifically limited, For example, it is a wire.

  In translucent sheet 10a, as shown in Drawing 1 (a), penetration hole 12 is directly formed in the upper end part, the left end part, and the right end part. In the example shown in FIGS. 1C and 1D, the translucent sheet 10a is folded at the upper end, the left end, and the right end of the translucent sheet 10a, and the folded piece is a facing portion. And sewn. Therefore, the upper end portion, the left end portion, and the right end portion of the translucent sheet 10a are reinforced by the folded piece. Through holes 12 are formed in the reinforced upper end portion, left end portion, and right end portion. A reinforcing ring (not shown) for reinforcing the inner peripheral edge is attached to the inner peripheral edge of the through hole 12. The light shielding sheet 10 b is attached to the fence 11 by connecting the through hole 12 and the mesh of the fence 11 with a connector. Although the kind of coupling tool is not specifically limited, For example, it is a wire.

  FIG. 3 is a view showing a state in which the vine prevention sheet 10 is attached to the fence 11 while the vine prevention sheets 10 are connected in the horizontal direction. 4 is an enlarged view of the region indicated by the arrow C in FIG. 3, (a) is a view of the region viewed from above, and (b) is a view of the region viewed from the front. .

  In order to connect the anti-winding sheet 10 to the fence 11 while connecting the anti-winding sheets 10 in the lateral direction, a connector 15 is used. The connector 15 includes, for example, two composite plates 15a having a structure in which a synthetic resin plate is sandwiched between both sides with an aluminum plate, and bolts and nuts 15b that connect the two composite plates 15a. The connector 15a is a lightweight and highly rigid belt-like member, and has a through hole through which the bolt 15b is inserted. The connector 15 is arranged such that its length direction is the vertical direction. The positions of the through holes correspond to the positions of the through holes 12 provided in the left and right end portions of the translucent sheet 10a and the left and right end portions of the light shielding sheet 10b.

  As shown in FIG. 4 (a), two composite plates 15a are arranged in such a manner that the anti-winding sheet 10 and the fence 11 are sandwiched from both sides in a portion where the adjacent anti-winding sheets 10 overlap each other. . At that time, the through holes 12 of each vine prevention sheet 10 and the through holes of each composite plate 15a are aligned. Then, the two composite plates 15a are connected by bolts and nuts 15b so that the anti-wound sheet 10 and the fence 11 are fastened by the two composite plates 15a. Thereby, the vine prevention sheet 10 can be attached to the fence 11 while connecting the vine prevention sheets 10 in the lateral direction. The band width of the composite plate 15a is, for example, 50 mm, and the wrap width between the translucent sheets 10a is, for example, 200 to 500 mm (see FIG. 4B).

  The bolt 15b is, for example, an M8 bolt. A through hole may be formed in the composite plate 15a in advance, but the through hole may be formed by drilling a hole on site. A special primer is applied to a region where the composite plate 15a and the light shielding sheet 10b overlap to bond the composite plate 15a and the light shielding sheet 10b. In addition, the dedicated primer needs to be sufficiently stretched with a metal spatula and bonded to both the upper and lower surfaces.

Next, a procedure for mounting the anti-wound sheet 10 to the fence 11 will be described.
First, when the area around the fence 11 surrounding the substation or the like is unprepared, the worker performs weeding in the installation range of the anti-winding sheet 10.

  After weeding, the operator prepares the ground so as not to be uneven as much as possible on the ground. In addition, when the rolling operation is performed, the finished product after the construction of the anti-bend sheet 10 is improved. In addition, when the ground is concrete, it is effective to clean the surface of the concrete and secure an adhesive surface with the light-shielding sheet 10b.

  Next, as described above, the worker fixes the lower end side of the vine winding prevention sheet 10 to the land surface 18 or the concrete ground 17 using the sheet terminal presser fitting 13 and the fixed pile 14. That is, in a state where the lower end portion of the light shielding sheet 10b is pressed from above by the sheet terminal holding metal fitting 13, the light shielding sheet 10b and the ground (the land surface 18 or the concrete ground 17) from the through hole 13 of the sheet terminal pressing member 13. On the other hand, the fixed pile 14 is driven vertically. When fixing the lower end side of the vine roll prevention sheet 10 to the concrete ground, the concrete ground and the light-shielding sheet 10b are bonded with a dedicated primer before driving the concrete fixing pile 14a. The sheet 10b can be firmly fixed to the concrete ground.

Next, the operator attaches the vine prevention sheet 10 to the wire rod of the fence 11 through a connector such as a wire in the through hole 12 of the vine prevention sheet 10. In addition, when connecting the anti-winding sheet 10 to the fence 11 while connecting the anti-winding sheet 10 in the horizontal direction, the connecting work is performed using the connecting tool 15.
As described above, the operator can firmly fix the vine roll prevention sheet 10 to the fence 11.

  As described above, according to the anti-bend sheet 10, the light-shielding sheet 10b is mounted on the fence 11 so as to rise from the ground, and therefore no gap is generated between the light-shielding sheet 10b and the ground. Therefore, it is possible to prevent the vines from entering between the light-shielding sheet 10b and the ground. Moreover, since the light-shielding sheet 10b is non-corrosive, it is not decomposed by bacteria and does not corrode even if it contacts the ground. In addition, a translucent sheet 10a is connected to the upper end portion of the light-shielding sheet 10b, and the translucent sheet 10a is attached to the fence 11 above the light-shielding sheet translucent sheet 10b. Therefore, the vine plant having habit of extending in the bright direction, after standing up from the ground, extends in the upward direction where the translucent sheet 10a exists, but the light-shielding sheet 10b and the translucent sheet 10a enter the fence 11 of the vine plant. Prevent tangling of When a vine plant rises to a certain height (for example, about 80 cm), it cannot be self-supported and warps backward. Therefore, it is possible to prevent the vine plants from getting over the translucent sheet 10a and the fence 11 and entering the site.

  Further, according to the vine winding prevention sheet 10, both the light shielding sheet 10b and the light transmitting sheet 10a are made of a flexible material and can be wound. Therefore, the user can carry the vine roll prevention sheet 10 while being wound in a roll shape, and can be attached to the fence while unfolding the roll, so that transportation and installation are easy.

  In addition, according to the anti-bend sheet 10, the polyester fiber has high strength, is not decomposed by bacteria, and is hardly corroded. Nonwoven fabrics are excellent in flexibility. Therefore, according to the sheet 10 for preventing vine winding, the sheet 10 for preventing vine winding excellent in non-corrosiveness and flexibility can be provided.

  In addition, according to the anti-bend sheet 10, the non-woven fabric is a recycled product of a PET bottle, and therefore the anti-bend sheet 10 can be manufactured using the recycled product as a material. Therefore, the anti-bend sheet 10 can be an ecological product that is kind to the earth.

  In addition, according to the anti-bend sheet 10, the belt-like reinforcing sheet 10c is attached to the translucent sheet 10a, so that the durability of the translucent sheet 10a can be improved. Further, by connecting the through hole 12 of the reinforcing sheet 10c and the mesh of the fence 11 with a connecting tool (for example, a wire), the translucent sheet 10a is attached to the fence 11, so that the translucent sheet 10a can be easily and reliably attached. It can be attached to the fence 11.

  Further, according to the vine prevention sheet 10, since the reinforcing ring is attached to the inner peripheral edge of the through hole 12 of the reinforcing sheet 10c, the inner peripheral edge of the through hole 12 hits a connecting tool (for example, a wire) and is cut off. Inconvenience can be prevented.

  Further, according to the vine winding prevention sheet 10, the lower end portion of the light-shielding sheet 10 b is pressed from above by the sheet terminal pressing member 13 and fixed to the ground by the sheet terminal pressing member 13 and the fixing pile 14. Therefore, it can prevent that a clearance gap arises between the light-shielding sheet | seat 10b and the ground, and can prevent reliably a vine plant invading from the clearance gap.

  In addition, according to the anti-winding sheet 10, when the concrete fixing pile 14b is used, the light shielding sheet 10b can be fixed to the concrete ground 17, and when the soil fixing pile 14b is used, The light-shielding sheet 10b can be fixed to the earth surface 18.

  Note that the color of the anti-wound sheet 10 can be, for example, a color such as gray or green, and the size of the anti-winding sheet 10 is, for example, 2 m × 40 m (height × full length) or 1 m × 40 m. It can be changed according to the size of the fence 11 such as (height × full length).

  The anti-bend sheet 50 is obtained by stitching a mesh-like translucent sheet 50a to the upper end of the light-shielding sheet 50b. Although the material of this translucent sheet | seat 50a is not specifically limited, For example, it is polyester.

  In addition, the filling ratio representing the ratio of the real area occupied by the mesh in the translucent sheet 50a (where the filling ratio is the ratio of the real area of the net / the outer area of the net) is about 0.3 to 0.9, etc. Various settings can be made according to the environment in which the anti-bend sheet 50 is used. Further, the wind force coefficient of the anti-wound sheet 50 is determined by the filling rate. In addition, the translucent sheet 50a can be used safely because it does not use a halogen-containing substance that causes dioxins during incineration. The mesh filling rate is set so as to ensure flatness that prevents the vines from being entangled.

  As described above, by using the mesh sheet 50a, the wind-preventing sheet 50 can reduce the wind pressure received by the anti-winding sheet 50 and can reduce the weight of the anti-winding sheet 50. Become. Therefore, the installation work to the fence 11 becomes easy, and the weight load to the fence 11 can also be reduced.

  In addition, although the dimension of each member is described in drawing, this dimension is an example, Comprising: It is not limited and can be changed arbitrarily.
