  According to the present invention, both the upper layer and the lower layer of the ant / weedproof sheet are formed of a non-woven fabric with a small (narrow) gap between the fibers, so that the ant / weedproof sheet is laid on the surface of the ground. Thus, it is possible to suppress the termites in the ground below the ant / weedproof sheet from passing through the ant / weedproof sheet and coming out to the ground surface. In particular, the ant-proof function is given to the lower layer of the ant-proof / weed-proof sheet, and it is avoided that termites break through this lower layer, so the termites break through the ant-proof / weed-proof sheet and come out to the surface. It can prevent more effectively. Therefore, even if an outdoor structure such as a garden deck is installed in the vicinity of the building, the ant / weedproof sheet of the present invention is laid on the surface of the ground below the outdoor structure. It is possible to prevent termites from climbing up the surface on the outdoor side of the foundation of a building that is shaded by a structure or an outdoor structure and entering the building.

  In addition, according to the present invention, since the upper layer of the ant / weedproof sheet blocks light, the growth of weeds is suppressed under the ant / weedproof sheet. Therefore, weeds can be prevented from extending from the ground on which the ant-proof / weed-proof sheet is laid and penetrated through the ant-proof / weed-proof sheet, and termites can be prevented from coming out from the penetrating portion. In addition, since the upper layer of the ant / weedproof sheet is easy to blend with water, the water spreads and penetrates into the upper layer without accumulating on the ant / weedproof sheet. For this reason, it is possible to prevent the ant / weedproof sheet from being submerged during rainy weather, and to prevent a puddle from remaining on the ant / weedproof sheet.

  In the ant-proof / herb-proof sheet of the present invention, preferably, the lower layer contains an ant-preventive agent to provide an ant-proof function.

  According to this configuration, since termites are repelled by the ant-preventing agent contained in the lower layer of the ant-proof / weedproof sheet, it is possible to prevent the termites from passing through the lower layer of the ant-proof / weedproof sheet. This ensures that the lower layer of the ant-proof / weed-proof sheet exhibits the ant-proof function.

  The ant-proof / weed-proof sheet of the present invention is preferably provided with an ant-proof function by the lower layer being a nonwoven fabric made of glass fiber.

  According to this structure, since termites cannot bite and break glass fiber (causes damage), termites are prevented from passing through the lower layer of the ant-proof / weed-proof sheet. This ensures that the lower layer of the ant-proof / weed-proof sheet exhibits the ant-proof function.

  In the ant / weedproof sheet of the present invention, the upper layer and the lower layer are preferably bonded by a needle punch or an adhesive layer.

  According to this configuration, the upper layer nonwoven fabric fiber and the lower layer nonwoven fabric fiber are entangled with each other by the needle punch, or the upper layer nonwoven fabric and the lower layer nonwoven fabric are joined to each other by the adhesive layer. The upper and lower layers of the ant / weedproof sheet are securely integrated.

  According to this configuration, since termites cannot bite (corrupt) the glass fibers, termites are prevented from passing through the lower layer 202 of the ant / weedproof sheet 200. Thereby, the lower layer 202 of the ant-proof / weed-proof sheet 200 surely exhibits the ant-proof function. Further, the upper layer 201 and the lower layer 202 are bonded together by the adhesive layer 203 so that the upper layer 201 and the lower layer 202 of the ant / weedproof sheet 200 are reliably integrated.

  In this case, for the adhesive layer 203, for example, a hot melt adhesive can be used. Basically, the adhesive layer 203 may or may not contain an ant protection agent. However, in this example, the lower layer 202 of the ant-proof / herb-proof sheet 200 is provided with an ant-proof function without using an ant-proof agent (non-chemitype), and similarly, the adhesive layer 203 is also non-chemi-functional. More preferably, it does not contain a type, i.e., an anti-anticide.

  Moreover, in the said embodiment, you may provide the dovetail protruding outside like at least one of the surface of the outdoor side of the foundation C, and the surrounding surface of the support leg 11 of the garden deck 1 like a spear.

  Further, in the ant / weedproof sheets 100 and 200, the upper layers 101 and 201 may be imparted with an ant-repellent function, and the lower layers 102 and 202 may be imparted with light-shielding properties and hydrophilicity.

  Moreover, you may use the ant / weedproof sheets 100 and 200 for an underfloor ant structure.

  For reference, the upper layer includes a non-woven fabric provided with an upper layer and a lower layer, the upper layer includes a light-shielding property, hydrophilicity, and durability (weather resistance), and the lower layer includes a non-functional non-woven fabric. An ant-proof / weed-proof sheet in which an ant-proof agent is contained in an adhesive layer (for example, a hot-melt adhesive) that binds can be proposed as an outdoor ant-proof / weed-proof sheet.

  Also, as a reference, it is composed of only one layer of non-woven fabric with light-shielding properties, hydrophilicity, and durability (weather resistance), and on the bottom surface (the surface that comes into contact with the ground when laid on the ground surface) An ant-proof / weed-proof sheet impregnated with an ant-proof agent can also be proposed as an outdoor ant-proof / weed-proof sheet.

  Needless to say, the various numerical values, materials, shapes, and the like described in the above embodiments are merely examples and are not limited thereto.
