図1aは、平面図、図1bはA-A’線における断面図である。図に示すように下部枠は基礎面から立ち上がる戴円錐形の筒部を連結したものであり、相接する2辺に雄継ぎ手、他の2辺に雌継ぎ手が設けられ、互いに左右に連結可能とされている。筒部が下部踏み圧部を形成し、筒部頂部が人あるいは車からの荷重を受ける部分であり、下部踏み圧部で囲まれた空間が下部透水部を形成し、土壌が充填され芝生等が生育する領域であると共に雨水等が地下に浸透していく領域でもある。下部踏み圧部は本図の構成を有するもの以外に、矩形あるいは多角形の各筒を連結したハニカム形状のものであってもよい。この場合、壁面が踏み圧部に該当し、角筒の内部が透水部に該当する。
Hereinafter, the present invention will be described in detail with reference to the drawings.
FIG. 1 is a conceptual diagram showing an example of a lower frame constituting the lawn protective material constituting the first invention.
FIG. 1A is a plan view, and FIG. 1B is a cross-sectional view taken along the line AA ′. As shown in the figure, the lower frame is a conical cylinder that rises from the base surface, and has a male joint on the two adjacent sides and a female joint on the other two sides. It is said that. The cylinder part forms the lower treading pressure part, the top part of the cylinder part receives the load from the person or the car, and the space surrounded by the lower treading pressure part forms the lower water permeable part, filled with soil, lawn etc. It is a region where rainwater etc. penetrates underground. The lower treading pressure portion may have a honeycomb shape in which rectangular or polygonal tubes are connected in addition to the configuration shown in this figure. In this case, the wall surface corresponds to the stepping pressure portion, and the inside of the square tube corresponds to the water permeable portion.
下部踏み圧部の頂部には十字の溝が切られ、後述する上部枠の網目の交点がその溝にはめ込まれ契合できるようになっている。 A cross-shaped groove is cut at the top of the lower stepping pressure portion, and an intersection of a mesh of an upper frame described later is fitted into the groove so that engagement can be made.
図2は本芝生保護材を構成する上部枠の例を示す概念図である。
図2aは、表面を表にした上部枠の平面図と断面図であり、図2bは裏面を表にした上部枠の平面図と断面図を示している。
FIG. 2 is a conceptual diagram showing an example of an upper frame constituting the lawn protective material.
2A is a plan view and a cross-sectional view of the upper frame with the front side as the front, and FIG. 2B is a plan view and a cross-sectional view of the upper frame with the back side as the front.
上部枠は網目状であり、図では格子状とされている。表面の格子には棒状の突起が設けられている。裏面には格子の交点を中心とする十字状の突起物が設けられ各格子に沿って低くなる滑り止めを形成している。上部枠には下部枠と異なり、上部枠同士を連結するための連結具は設けられていない。下部枠同士を連結した後、上部枠を下部枠上に契合し、上部枠同士を互いに連結すると広い面積に配設した場合、歪が蓄積し上部枠同士の連結が困難となる場合がありその不都合を避けるためである。 The upper frame has a mesh shape, and is a lattice shape in the figure. Bar-shaped protrusions are provided on the surface lattice. On the back surface, a cross-shaped protrusion centering on the intersection of the lattices is provided to form a slip stopper that is lowered along each lattice. Unlike the lower frame, the upper frame is not provided with a connector for connecting the upper frames. After connecting the lower frames, if the upper frame is engaged on the lower frame and the upper frames are connected to each other, if they are arranged in a large area, distortion may accumulate and it may be difficult to connect the upper frames. This is to avoid inconvenience.
図3は、本第1の発明を構成する芝生保護材を構成する第2の上部枠の例を示す概念図である。素材はエラストマーなどの柔らかい弾性に富んだ部材で成形することが好ましい。図に示すように、上端部が閉鎖し、下端が開放された筒状部を連結したものである。図2aに示す上部枠の表面に設けられた棒状の突起物に、筒状部が突起物と筒状部の内壁面との間に隙間を設けて挿入される。人の踏み圧により筒状部がつぶれ、筒状部開放端から内部の空気を放出する。 FIG. 3 is a conceptual diagram showing an example of a second upper frame constituting the lawn protective material constituting the first invention. The material is preferably formed of a soft and elastic member such as an elastomer. As shown in the drawing, a cylindrical portion whose upper end is closed and whose lower end is opened is connected. The cylindrical portion is inserted into the rod-shaped projection provided on the surface of the upper frame shown in FIG. 2a with a gap between the projection and the inner wall surface of the cylindrical portion. The cylindrical part is crushed by the stepping pressure of the person, and the air inside is released from the open end of the cylindrical part.
図4は、下部枠に上部枠を、その表面を上にして契合した状態を示している。
図に示すように棒状の筒状部が林立した状態となっている。上部枠は下部踏み圧部頂部に設けた十字の溝にその格子の交点を対応させるように契合する。
FIG. 4 shows a state in which the upper frame is engaged with the lower frame with its surface facing up.
As shown in the figure, the rod-shaped cylindrical portion is in a forested state. The upper frame engages with the cross groove provided at the top of the lower stepping pressure portion so as to correspond to the intersection of the lattice.
図5は、図4に示した下部枠と上部枠との組み合わせに更に第2の上部枠を契合させた状態を示している。このような3層構造とすることによって下部踏み圧部上にエラストマー製の柔らかい踏み圧によって内部の空気を放出する第2の上部枠が契合可能となる。 FIG. 5 shows a state in which the second upper frame is further engaged with the combination of the lower frame and the upper frame shown in FIG. With such a three-layer structure, it is possible to engage with the second upper frame for releasing the internal air by the soft foot pressure made of elastomer on the lower foot pressure portion.
図6は、下部枠上に上部枠をその裏面を表にして契合した状態を示している。
図に示すようにその表面には格子の交点を頂点として4方に傾斜した山が設けられ人などの歩行時の滑り止めを形成している。
FIG. 6 shows a state in which the upper frame is engaged with the lower frame on the lower frame.
As shown in the figure, the surface is provided with a mountain that is inclined in four directions with the intersection of the lattice as a vertex to form a slip stopper when a person or the like walks.
本芝生保護材の材質は、下部枠はコンクリート製品あるいは射出成形可能なポリオレフィンなどで製造され上部枠は人の踏圧を軽減するため射出成形可能なポリオレフィンなどで製造される。上部枠と下部枠の透水部の少なくとも一部は雨水等が地中に浸透可能となるよう、上下に連通するように配列することが好ましい。また上部枠と下部枠の踏み圧部も、上からの踏み圧を下部枠にて支えるため、少なくともそれら一部は一対一に対応していることが好ましい。
第2の上部枠の材質は、踏圧により空気を供給するためゴムなどを含むエラストマー製が好ましいのは上述したとおりである。
As for the material of this lawn protective material, the lower frame is manufactured from concrete products or injection-moldable polyolefin, and the upper frame is manufactured from injection-moldable polyolefin to reduce human treading pressure. It is preferable that at least a part of the water permeable portions of the upper frame and the lower frame are arranged so as to communicate vertically with each other so that rainwater can penetrate into the ground. Further, it is preferable that at least some of the stepping pressure portions of the upper frame and the lower frame correspond one-to-one in order to support the stepping pressure from above by the lower frame.
As described above, the material of the second upper frame is preferably made of an elastomer containing rubber or the like in order to supply air by a stepping pressure.
本芝生保護材の使用方法は、路盤上に下部枠を連結敷き設し、土壌を下部透水部に充填し、転圧し、芝生をほぐして撒き、上部枠必要に応じて第2の上部枠を契合して、図7に示すような状態となるよう芝の生長を待つ、あるいは転圧後、上部枠を接続し、上部枠の頂部まで土壌と芝の種を混合して充填し芝の成長を待つなど適宜実施することができる。 The lawn protective material is used by linking and laying a lower frame on the roadbed, filling the soil with the lower water-permeable section, rolling it, loosening the lawn, and spreading the second upper frame if necessary. Engage and wait for turf to grow as shown in Fig. 7, or after rolling, connect upper frame, mix soil and turf seeds to top of upper frame, and grow turf It can be implemented as appropriate, such as waiting.
