Therefore, the reaction force from the treading pressure part becomes more uniform and reduced.
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上部部材の平面図であり、図１ｂは正面図、図１ｃはA−A’線での断面図、図１ｄはB−B’線での上部接続部を示す拡大部分断面図である。図に示すとおり、本上部部材は格子状のリブの各交点に袋状の上部踏圧部が設けられている。基礎踏み圧部と接続する接続部は、４つの踏み圧部を連結したリブで形成された正方形の内方に各リブに一箇所づつ接続部が設けられ、上部接続部を形成している。上部接続部は水平に突出する板状部材で先端が鋭角状に形成されている。
Hereinafter, the present invention will be described in detail with reference to the drawings.
1a is a plan view of an upper member of the plant protection material, FIG. 1b is a front view, FIG. 1c is a cross-sectional view taken along the line AA ', and FIG. 1d shows an upper connection part taken along the line BB'. It is an expanded partial sectional view. As shown in the figure, the upper member is provided with a bag-like upper treading pressure portion at each intersection of the grid-like ribs. The connecting portion connected to the basic treading pressure portion is provided with a connecting portion for each rib on the inner side of a square formed by ribs connecting the four treading pressure portions, thereby forming an upper connecting portion. The upper connecting portion is a plate-like member that protrudes horizontally, and has a tip formed at an acute angle.
図２ａは本植物保護資材の基礎部材の平面図であり、図２ｂは断面図である。本基礎部材は戴円錐形の突部を上部踏圧部とし、それらをリブで連結したものである。上部踏み圧部で囲まれた空間は最下面に透孔が設けられ、当該空間に土壌を充填し芝などの植物が育成しかつ雨水が地中に浸透する場所となっている。上部部材との接続部である上部接続部は踏圧部の頂部に設けられている。上部接続部は踏圧部の頂部は一段高く形成されその肩口に設けられた透かし孔である。直交するように透かし孔が４箇所設けられている。 Fig. 2a is a plan view of the basic member of the plant protection material, and Fig. 2b is a cross-sectional view. This basic member is a conical protrusion formed as an upper treading pressure portion and connected by a rib. The space surrounded by the upper stepping pressure part is provided with a through hole in the lowermost surface, where the space is filled with soil, plants such as turf grow and rainwater penetrates into the ground. The upper connection part which is a connection part with an upper member is provided in the top part of the treading pressure part. The upper connecting portion is a watermark hole formed at the shoulder of the top of the stepping pressure portion that is formed one step higher. Four watermark holes are provided so as to be orthogonal to each other.
上部部材と基礎部材との接続は、図３に示すとおり、上部接続部の鋭角部が透かし孔に挿入される際、上方に曲がり挿入後元の形状に戻ることで成される。接続部の形状は本例に限らず既存の方法を適宜使用することができる。 As shown in FIG. 3, the connection between the upper member and the base member is made by bending upward and returning to the original shape after insertion when the acute angle portion of the upper connection portion is inserted into the watermark hole. The shape of the connecting portion is not limited to this example, and an existing method can be used as appropriate.
図４は、本植物保護資材における上部部材の他の例を示す概念図である。本例は、リブの交点に袋状の突部は存在せず平坦な交点となっている。接続部の形状は上記例と同一である。 Drawing 4 is a key map showing other examples of the upper member in this plant protection material. In this example, there is no bag-like protrusion at the intersection of the ribs, and this is a flat intersection. The shape of the connecting portion is the same as in the above example.
図５は既存の植物保護資材と本植物保護資材との差異を示す図である。図5ａは従来の植物保護資材を構成する上部部材のリブの交点、即ち上部踏圧部に基礎部材との接続部を設けたものである。図５ｂは本植物保護資材の例を概念的に示したものである。
それぞれ同一形状の基礎部材上に同一間隔に上部踏圧部を設けた上部部材を接続した状態を示している。上部踏圧部を同一間隔に配列したにもかかわらず、同一面積中従来の植物保護資材は25個の上部踏み圧部となり、本植物保護資材は３６個の上部踏圧部となっている。踏み圧部の数が多いほど人がその上を歩くとき、踏圧部から受ける反力は均等となりより柔らかく感じられる。
FIG. 5 is a diagram showing a difference between an existing plant protection material and the present plant protection material. FIG. 5a shows an intersection of ribs of an upper member constituting a conventional plant protection material, that is, an upper stepping pressure portion provided with a connection portion with a base member. FIG. 5 b conceptually shows an example of the present plant protection material.
The state which connected the upper member which provided the upper treading part at the same space | interval on the base member of the same shape, respectively is shown. In spite of arranging the upper stepping pressure parts at the same interval, the conventional plant protection material has 25 upper stepping pressure parts in the same area, and this plant protection material has 36 upper stepping pressure parts. The more the number of treading parts, the more the reaction force received from the treading part is felt when the person walks on it.
雨水等が芝等の植物に供給されるよう、本植物保護資材において、上部透水部と基礎透水部の位置は少なくともその一部は上下に貫通する貫通するように形成されていることが好ましい。本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。 In this plant protection material, it is preferable that at least a part of the position of the upper water permeable portion and the basic water permeable portion is formed so as to penetrate vertically through the plant protective material so that rainwater or the like is supplied to plants such as turf. As the plant protection material, a thermoplastic resin such as polyolefin is generally used.
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.
