Abstract
Description
本発明は、枠体を複数層状に重ねる芝生などの保護材における上部枠の保護技術である。 The present invention is a technique for protecting an upper frame in a protective material such as lawn in which frames are stacked in a plurality of layers.
芝生やその他の植物を育成させた広場として、ゴルフ場、運動場、公園、庭園、工場の路側、各種の敷地空間内があり、古くは芝生保護のため芝生内は立ち入り禁止とする場合が普通であった。最近では芝生内に立入る人の、あるいは車の踏圧から植物を保護するための図９に示すような踏圧部と透孔部からなる植物保護材（特開平2-145137、特開平4-75541、特開平5-56724）などが各種提案され使用されている。これらの植物保護材は格子状のリブの交点に踏圧部を設け、踏み圧部で囲まれた空間を透水部として芝生などの植物の育成区間とし、同時に雨水が地中に浸透する領域としている。また、これら芝生などの保護材で、踏圧からの反動を和らげるため、地盤に設置する基礎枠の上部に柔らかい素材もしくは踏圧の面積を大きくした上部枠を接続した複層の保護材がある。
更に小中学校の校庭あるいは保育園の園庭など子供たちに緑の芝生に親しんでもらう目的のため上部踏み圧部をエラストマー等の柔軟な素材を用いた筒状とし踏み圧により収縮し、内部の空気を噴出すことにより更に踏み圧を軽減した植物保護材が本発明者らにより特開2008-35856に開示されている。
本保護材においては上部踏み圧部が長期の使用の場合、斜めからの力により折り曲げられ亀裂などを発生する危惧がありその解消策が求められていた。
There are golf courses, playgrounds, parks, gardens, factory roadsides, and various site spaces as open spaces where lawns and other plants were nurtured. there were. Recently, a plant protective material comprising a stepping pressure portion and a through hole as shown in FIG. 9 for protecting a plant from the pressure of a person entering the lawn or a car (JP-A-2-145137, JP-A-4-75541). JP-A-5-56724) has been proposed and used. These plant protection materials are provided with a treading pressure section at the intersection of the grid-like ribs, and the space surrounded by the treading pressure section is used as a water permeable section to grow plants such as lawns, and at the same time, rainwater penetrates into the ground. . Moreover, in order to relieve the reaction from the treading pressure with a protective material such as lawn, there is a multi-layered protective material in which a soft material or an upper frame with a larger treading pressure area is connected to the upper part of the foundation frame installed on the ground.
Furthermore, for the purpose of allowing children to become familiar with the green lawn, such as elementary and junior high school schoolyards or nursery school gardens, the upper treading pressure part is made into a cylindrical shape using a flexible material such as elastomer, and the inside air is shrunk by the treading pressure. JP 2008-35856 discloses a plant protective material in which the stepping pressure is further reduced by ejecting the water.
In this protective material, when the upper stepping pressure part is used for a long period of time, there is a concern that it may be bent by a force from an oblique direction to cause a crack or the like, and a solution for the problem has been demanded.
本発明は、枠体を複数層状に重ねる芝生などの保護材における上部枠の保護方法の提案にある。 This invention exists in the proposal of the protection method of the upper frame in protection materials, such as a lawn which piles up a frame body in multiple layers.
本発明は、地盤に接する基礎枠と基礎枠上に接続される中間枠と中間枠上に接続される上部枠からなり、基礎枠は左右前後に連結可能な連結部を有し、中間枠および上部枠は各枠同士を左右前後に連結する連結部を保有せず、基礎枠は基礎踏み圧部と基礎透孔部からなり、基礎踏み圧部は筒状の突部で互いに連結され、その頂部で上方から掛かる踏み圧を支えると共に中間枠との接続部を備え、基礎透孔部は基礎踏み圧部に囲まれた空間若しくは筒部内部であり、中間枠は網目状の枠であってその網目の交点の一部はその裏面で基礎踏み圧部の頂部と係合可能とされ、網目の交点の上部には棒状の挿入部が設けられ、上部枠は基礎枠と比較し柔軟な素材で形成され、上部枠は頂部が閉じ下方が開放された中空の筒である上部踏み圧部を網目状に接続した形状とされ、筒により囲まれた空間が上部透水部とされ、前記中間枠の棒状の挿入部が上部枠の筒に挿入可能とされた芝生等の保護材において、上部枠の上部踏み圧部の下部を囲む保護管を連結した上部踏み圧部保護枠を重ねた4層構造とした芝生等の保護材である。
斜めの力に対して、上部踏み圧部がその根元で折り曲げられることを防止するため、上部踏み圧部の周囲を保護管で囲った。
本第2の発明は、上記発明である４層構造とした芝生等の保護材において、基礎枠を除いた3層の芝生等の保護材である。踏み圧として小さな荷重のみが期待できる場合は、基礎枠なしでも十分踏み圧の吸収が可能となるため基礎枠を外すことができる。
The present invention comprises a foundation frame in contact with the ground, an intermediate frame connected on the foundation frame, and an upper frame connected on the intermediate frame, the foundation frame having a connecting part that can be connected to the left and right, front and rear, The upper frame does not have a connecting part that connects the frames left and right and back and forth, the base frame consists of a basic treading pressure part and a basic through hole part, and the basic treading pressure part is connected to each other with a cylindrical protrusion, It supports the stepping pressure applied from the top at the top and has a connection part with the intermediate frame, the basic through hole part is the space surrounded by the basic stepping pressure part or inside the cylinder part, and the intermediate frame is a mesh frame Part of the intersection of the mesh can be engaged with the top of the foundation treading pressure part on the back side, a bar-shaped insertion part is provided above the intersection of the mesh, and the upper frame is a flexible material compared to the foundation frame The upper frame is formed in a mesh shape with the upper stepping pressure part being a hollow cylinder with the top closed and the lower open In a protective material, such as lawn, in which the space that is connected and the space surrounded by the cylinder is the upper water-permeable portion, and the rod-shaped insertion portion of the intermediate frame can be inserted into the cylinder of the upper frame, the upper step of the upper frame It is a protective material such as lawn that has a four-layer structure with an upper treading pressure part protection frame connected to a protective pipe that surrounds the lower part of the pressure part.
In order to prevent the upper stepping pressure part from being bent at the base against an oblique force, the upper stepping pressure part was surrounded by a protective tube.
The second invention is a protective material for lawn or the like having a four-layer structure according to the above-described invention, such as a three-layer lawn or the like excluding a basic frame. When only a small load can be expected as the stepping pressure, the foundation frame can be removed because the stepping pressure can be sufficiently absorbed without the foundation frame.
本発明は、柔軟な材料で形成される上部踏み圧部の下部をリング状の保護管で覆ったため、斜めからの力が断続的に長期に加わった場合でも上部踏み圧部が傾いたりしないので疲労などによる亀裂による破損・脱落が防止できる。 In the present invention, since the lower part of the upper stepping pressure part formed of a flexible material is covered with a ring-shaped protective tube, the upper stepping pressure part does not tilt even when an oblique force is applied intermittently over a long period of time. It can prevent damage and dropout due to cracks due to fatigue.
以下本発明を図により詳細に説明する。
図１から図４までは、本発明に係る植物保護材を構成する基礎枠、中間枠、上部枠および上部枠保護枠の例を示す概念図である。
図１は、基礎枠の概念図である。図１ａは平面図、図１ｂは、A-A線での断面図である。
図１に示すように、基礎枠は戴円錐形の踏み圧部が連結されたもので、踏み圧部で囲まれた領域が土壌を充填し芝等の育成場所となると共に雨水等が地中に浸透する場所となっている。踏み圧部頂部には、後述する中間枠が係合できるよう十字の溝が設けられている。基礎枠の相接する2辺には雄継ぎ手、他の2辺には雌継ぎ手が設けられ互いに連結しながら左右前後に連結可能とされている。
基礎枠は図示した形状に限らず、角筒をハニカム状に並べ、角筒縁を基礎踏み圧部、角筒内部を基礎浸透部とするものであってもよい。
Hereinafter, the present invention will be described in detail with reference to the drawings.
1 to 4 are conceptual diagrams showing examples of a basic frame, an intermediate frame, an upper frame, and an upper frame protective frame constituting the plant protective material according to the present invention.
FIG. 1 is a conceptual diagram of a basic frame. 1a is a plan view, and FIG. 1b is a cross-sectional view taken along the line AA.
As shown in FIG. 1, the foundation frame is a conical stepping pressure part connected, and the area surrounded by the stepping pressure part is filled with soil and becomes a growing place for grass and rainwater etc. It has become a place to penetrate. A cross groove is provided at the top of the stepping pressure portion so that an intermediate frame described later can be engaged therewith. A male joint is provided on the two sides of the foundation frame that are in contact with each other, and a female joint is provided on the other two sides.
The base frame is not limited to the illustrated shape, and square tubes may be arranged in a honeycomb shape, and the edge of the square tube may be a basic stepping pressure portion and the inside of the square tube may be a basic permeation portion.
図２は、本植物保護材を構成する中間枠の例を示す概念図である。図２ａは、平面図、図２ｂは、A-A線での断面図である。
中間枠は、網目状であるが図では格子状とされ、格子の表面の交点に上方に突出する棒状の挿入部が設けられている。裏面には基礎踏み圧部と対応する部分に基礎枠と係合するための契合具が設けられている。本契合具は基礎踏み圧部頂部を十字状に溝を設けた際に残る扇形の縁部を押し下げるように押し込み、前記縁部が再び元の位置に戻ることで係合を確実としている。基礎踏み圧部頂部と中間枠の係合は本方法に限らず既存の方法で実施可能である。
FIG. 2 is a conceptual diagram showing an example of an intermediate frame constituting the plant protection material. 2a is a plan view, and FIG. 2b is a cross-sectional view taken along the line AA.
The intermediate frame has a mesh shape but is a lattice shape in the figure, and a bar-shaped insertion portion that protrudes upward is provided at the intersection of the surface of the lattice. On the back surface, a fitting for engaging with the foundation frame is provided at a portion corresponding to the foundation treading pressure portion. In this engagement tool, the top of the basic stepping pressure part is pushed in so as to push down the fan-shaped edge remaining when the groove is provided in a cross shape, and the edge is returned to the original position again to ensure the engagement. The engagement between the top of the basic stepping pressure portion and the intermediate frame is not limited to this method, and can be implemented by an existing method.
図３は、本植物保護材を構成する上部枠の例を示す概念図である。
図３ａは、平面図、図３ｂは、A-A線での断面図である。
図に示すように上部枠は、上部踏み圧部と上部浸透部からなり、上部踏み圧部は、上部が閉端し下方に開口した筒状部をリブで繋げた構成を有する。上部浸透部は上部踏み圧部で囲まれた領域であり、基礎浸透部と連通するように構成される。
本上部枠は他の枠体と異なり柔軟な素材であるエラストマー、ゴムなどで成形されることが好ましい。各筒状部内に中間枠の挿入部が挿入されるようになっている。本上部踏み圧部は、人の踏み圧により収縮し、中の空気が押し出されるためより柔らかい踏み圧となり、小中学校の校庭、保育園の園庭など児童・生徒に優しい芝生保護材となる。
FIG. 3 is a conceptual diagram showing an example of an upper frame constituting the plant protection material.
3A is a plan view, and FIG. 3B is a cross-sectional view taken along the line AA.
As shown in the figure, the upper frame is composed of an upper stepping pressure portion and an upper permeation portion, and the upper stepping pressure portion has a configuration in which a cylindrical portion whose upper end is closed and opened downward is connected by a rib. The upper permeation part is an area surrounded by the upper stepping pressure part, and is configured to communicate with the basic permeation part.
The upper frame is preferably formed of an elastomer, rubber or the like, which is a flexible material unlike other frame bodies. An insertion part of the intermediate frame is inserted into each cylindrical part. This upper stepping pressure part is shrunk by a person's stepping pressure, and the air inside is pushed out, so that it becomes a softer stepping pressure.
図４は、上部枠保護枠は円筒状の保護管をリブで連結した構造を有し、各保護管が各上部枠踏み圧部の基礎部を囲むように構成されている。そのため、好ましくは上部枠の上部踏み圧部を連結するリブ、上部枠保護枠の保護管を連結するリブは平坦なものが好ましい。
各保護管が上部踏み圧部の基礎部を囲むことにより、上部踏み圧部に斜めからの踏み圧が掛かる場合であっても、本保護管により保護されているため、上部踏み圧部が倒れたり、あるいは上部踏み圧部が挿入棒から外れるなどして上部踏み圧部の基礎部を損傷するような事態が防止でき、長期の使用が可能となる。
In FIG. 4, the upper frame protective frame has a structure in which cylindrical protective tubes are connected by ribs, and each protective tube is configured to surround the base portion of each upper frame stepping pressure portion. Therefore, it is preferable that the rib connecting the upper step pressure portion of the upper frame and the rib connecting the protective tube of the upper frame protection frame are flat.
Since each protective pipe surrounds the base of the upper stepping pressure part, even if a stepping pressure is applied to the upper stepping pressure part from an oblique direction, the upper stepping pressure part falls down because it is protected by this protective pipe. Or the situation where the upper stepping pressure part is detached from the insertion rod and the base part of the upper stepping pressure part is damaged can be prevented, and long-term use is possible.
図５、および図６は基礎枠、中間枠、上部枠および上部枠保護枠を、組立て本植物保護材とする手順を示している。本第1の植物保護材は、図６ａ、ｃに示したとおり、下から順に基礎枠、中間枠、上部枠および上部枠保護枠を組み合わせた構造となっている。また本第2の植物保護材は、図６ｂ、ｄ、ｅに示したとおり、中間枠、上部枠および上部枠保護枠を組み合わせた構造となっている。図６ｄは、図６ｂのA-A’線での断面図、図６ｅはB-B’線での断面図である。 5 and 6 show a procedure in which the base frame, the intermediate frame, the upper frame, and the upper frame protection frame are assembled into the plant protection material. As shown in FIGS. 6a and 6c, the first plant protection material has a structure in which a base frame, an intermediate frame, an upper frame, and an upper frame protection frame are combined in order from the bottom. In addition, the second plant protection material has a structure in which an intermediate frame, an upper frame, and an upper frame protection frame are combined as shown in FIGS. 6d is a cross-sectional view taken along the line A-A 'of FIG. 6b, and FIG. 6e is a cross-sectional view taken along the line B-B'.
図７ａは、本第1の植物保護材を複数並べた状態を示しており、基礎枠は互いに前後に連結されているが、その他の中間枠、上部枠、上部枠保護枠は互いを連結することなく自由な状態となっている。これは、本第1の植物保護材を広い範囲に敷き設した場合、地盤のでこぼこなどにより、歪が溜まり上部に行くほど連結が困難となる。また、連結が成された場合においても、冬季、夏季の施工時期の差による熱歪による延び縮みで植物保護材が盛り上がったりすることがあるため、これらの不都合を避けるため中間枠より上部の枠相互間の連結は行わないことが好ましい。 FIG. 7a shows a state in which a plurality of the first plant protection materials are arranged, and the basic frame is connected to the front and back, but the other intermediate frame, upper frame, and upper frame protection frame are connected to each other. It is in a free state without. This is because, when the first plant protection material is laid in a wide range, the strain becomes accumulated due to bumps in the ground and the connection becomes more difficult as it goes to the upper part. In addition, even when the connection is made, the plant protection material may rise due to expansion and contraction due to thermal strain due to differences in construction time in winter and summer, so in order to avoid these disadvantages, the frame above the intermediate frame It is preferable not to connect each other.
図７ｂは、本第2の植物保護材を複数並べた状態を示している。
本第２の植物保護材は、図に示すとおり、上記４層構造の第1の植物保護材のうち基礎枠を外した3層構造の植物保護材である。
踏み圧が小さく、例えば幼児などの集う保育園などに適応できるものである。
FIG. 7 b shows a state in which a plurality of the second plant protection materials are arranged.
This 2nd plant protection material is a plant protection material of the 3 layer structure which removed the basic frame among the 1st plant protection materials of the said 4 layer structure, as shown in a figure.
The stepping pressure is small, and it can be applied to a nursery school where infants gather.
図８は、本第1および第２の植物保護材が適応され芝が育成された状態を示してある。図に示すように、基礎透水部に土壌が充填され、そこで芝などが育成される。図８ａは4層構造である第1の植物保護材の例であり、図８ｂは３層構造である第2の植物保護材の例である。第2の植物保護材では土壌の上に直接敷き設される。、
芝は、上部枠の上部浸透部から延伸し、全体が緑の芝で覆われるようになる。
FIG. 8 shows a state where the first and second plant protection materials are applied and grass is grown. As shown in the figure, the basic water-permeable portion is filled with soil, where turf and the like are grown. FIG. 8a is an example of a first plant protection material having a four-layer structure, and FIG. 8b is an example of a second plant protection material having a three-layer structure. The second plant protection material is laid directly on the soil. ,
The turf extends from the upper permeation part of the upper frame and is entirely covered with green turf.
基礎枠、中間枠および上部枠保護枠までポリプロピレンあるいはポリエチレン等の熱可塑性樹脂が使用できる。上部枠は特に踏圧を和らげるため上述したようにエラストマーあるいはゴム製とすることができる。 Thermoplastic resins such as polypropylene or polyethylene can be used up to the base frame, intermediate frame and upper frame protective frame. The upper frame can be made of an elastomer or rubber as described above in order to alleviate the pedaling pressure.
