以下、本発明を図により詳細に説明する。
図１ａは本植物保護資材の裏面から見た平面図であり、図１ｂは使用状態での断面図である。図１ａに示すように本植物保護資材はリブを格子状に配列し、その交点上に中空の上端が閉じた筒が設けられている。断面図で示すように筒部はその上端が閉じられ下端で開口している。さらにリブの交点より棒状部材が柱状に筒内部に設けられている。さらに棒状部材は筒内部の天井部まで立ち上がり天井部と一体的に固着されている。 Hereinafter, the present invention will be described in detail with reference to the drawings.
FIG. 1a is a plan view seen from the back side of the plant protection material, and FIG. 1b is a sectional view in use. As shown in FIG. 1a, the plant protection material has ribs arranged in a lattice pattern, and a hollow cylinder whose upper end is closed is provided on the intersection. As shown in the cross-sectional view, the cylindrical portion has its upper end closed and opened at its lower end. Furthermore, a rod-like member is provided in the cylinder in a column shape from the intersection of the ribs. Furthermore, the rod-shaped member rises up to the ceiling portion inside the cylinder and is fixed integrally with the ceiling portion.

本植物保護資材は、図では格子状のリブの交点上に筒が設けられているが、リブは格子状である必要はなく曲線状のリブの組合せであってもよい。リブの交点上に筒が設けられていればよい。
直線状のリブであれ曲線状のリブであれ、交点で踏み圧を支え、リブ間の隙間から芝生などが育成し伸長し、雨水が地中に浸透できるようになっていればよい。また互いに左右に連結可能な連結具を設けておくこともできる。連結具は既存の手段が適宜利用可能である。 In the drawing, the plant protection material is provided with a cylinder on the intersection of the grid-like ribs, but the ribs need not be grid-like and may be a combination of curved ribs. The cylinder should just be provided on the intersection of a rib.
Whether it is a straight rib or a curved rib, it is sufficient that the treading pressure is supported at the intersection, and lawn grows and extends from the gap between the ribs so that rainwater can penetrate into the ground. Moreover, the connection tool which can be connected mutually right and left can also be provided. Existing means can be used as appropriate for the coupler.

踏み圧からの反力を軽減するため、筒部の上端を柔軟な素材で形成することもできる。例えば、本植物保護資材をポリオレフィンなどの熱可塑性の樹脂で形成し、筒部頂部をエラストマーなどとするなど材料を換えることでもよい。 In order to reduce the reaction force from the stepping pressure, the upper end of the cylindrical portion can be formed of a flexible material. For example, the plant protection material may be formed of a thermoplastic resin such as polyolefin, and the material may be changed such that the top of the cylinder portion is an elastomer.

図2は、本植物保護資材の基礎部に使用する基礎保護資材の一例を示す。本植物保護資材単独でも芝などの保護に使用可能であるが、軽量車輌の出入りする踏み圧が大きくなる場所での芝生などの保護には強度が不足する場合がある。強度不足を補うため、本植物保護資材の下部に使用する。従来から駐車場用などに使用される保護資材であり、突状の踏み圧部と踏み圧部に囲まれた透水部からなっている。透水部には土壌が充填され芝などの植物が育成され、同時に雨水などが地中に浸透できるようになっている。 FIG. 2 shows an example of a basic protective material used for the foundation of the plant protective material. Although this plant protection material alone can be used to protect turf and the like, there is a case where strength is insufficient for protection of turf or the like in a place where the stepping pressure of entering and exiting a lightweight vehicle increases. Use to the bottom of the plant protection material to make up for the lack of strength. It is a protective material conventionally used for parking lots, etc., and consists of a projecting step pressure part and a water permeable part surrounded by the step pressure part. The permeable part is filled with soil and plants such as turf are nurtured, and at the same time rainwater can penetrate into the ground.

図３は上記2つの保護資材を組み合わせた状態を示している。
強度の高い踏圧部を有する図２に示す基礎保護資材である従来の植物保護資材の上に図１に示す本植物保護資材を契合させた使用例である。土壌を部材図２の部材の高さまで充填するため、芝生の育成によりすぐれた環境を提供できる。 FIG. 3 shows a state in which the above two protective materials are combined.
FIG. 3 is a usage example in which the plant protection material shown in FIG. 1 is combined with the conventional plant protection material which is the basic protection material shown in FIG. Since the soil is filled up to the height of the member shown in FIG. 2, an excellent environment can be provided by growing the lawn.

図4〜図６は、本植物保護資材のリブの間に基礎保護資材との契合部を設けた例で上記のものと同様に使用できる。
本植物保護資材は筒部を上として使用するのが普通であるが、筒部を下面にして使用することも可能である。 4-6 is an example which provided the engagement part with the basic protection material between the ribs of this plant protection material, and can be used similarly to the above.
The plant protection material is usually used with the tube portion on top, but can also be used with the tube portion on the bottom surface.

上記二つの植物保護資材と契合するよう、それぞれの植物保護資材に対応して基礎保護資材の頂部には本植物保護資材が契合できるような溝が設けられている。契合方法は本例に限らず既存の方法が使用できる。 In order to engage with the two plant protection materials, a groove is provided at the top of the basic protection material so that the plant protection material can be engaged with the plant protection material. The agreement method is not limited to this example, and an existing method can be used.

雨水等が芝等の植物に供給されるよう、本植物保護資材、基礎保護資材である従来の植物保護資材の透水部は少なくともその一部は上下に貫通するように形成されていることが好ましい。従来の植物保護資材はポリオレフィンなどの熱可塑性樹脂が一般的に使用される。 It is preferable that at least a part of the water-permeable portion of the conventional plant protection material, which is a basic protection material, is vertically penetrated so that rainwater is supplied to plants such as turf. . Conventional plant protection materials generally use thermoplastic resins such as polyolefins.

本植物保護資材は一般的な芝生保護に使用されるが、学校の校庭緑化に最適に使用できる。 This plant protection material is used for general lawn protection, but it can be optimally used for schoolyard greening.
