建造物における外断熱の効果が認知されて、今日では、建物の屋上等においても下地に断熱材を敷設する工法が広く採用されている。 他方、建造物の屋上やその他の空間に大規模に植物を植栽し、都市部における無機的な空間の緑化を図る試みが盛んになされるようになっている。 そして、両者の併設により効率的な省エネ効果を実現することができる。   The effect of external heat insulation in a building has been recognized, and today, a construction method in which a heat insulating material is laid on the ground is widely adopted even on the roof of a building. On the other hand, plants are planted on a large scale on the rooftops of buildings and other spaces, and attempts are being made to greenen inorganic spaces in urban areas. And an efficient energy-saving effect is realizable by coexistence of both.

図４は、従来の外断熱と屋上緑化の複合構造を示す一部切欠断面図である。図において、１はコンクリート下地、２はコンクリート下地１上に張設される防水層、３は植物の毛根等の侵出を防止するために前記防水層２上に固着張設されるルートガード、４はルートガード３上に設けられる断熱基盤で、発泡スチロールなどの断熱材から形成されている。 この断熱基盤４上にはフィルター５を介して客土層６が積層され種々の植物が植栽されるようになっている。 そして、前記断熱基盤４の表面すなわちフィルター５を介して客土層６に接する面には通水溝４a、４aが格子状に配設され、裏面すなわち防水層２と接する面には排水溝４ｂ、４ｂが格子状に配設されていて、排水溝４ｂを流れる水は、別途の廃水処理機構（不図示）に流下することになる。   FIG. 4 is a partially cutaway cross-sectional view showing a conventional composite structure of outer heat insulation and rooftop greening. In the figure, 1 is a concrete base, 2 is a waterproof layer stretched on the concrete base 1, 3 is a root guard fixedly stretched on the waterproof layer 2 to prevent the extruding of plant hair roots, etc. Reference numeral 4 denotes a heat insulating base provided on the root guard 3 and is formed from a heat insulating material such as polystyrene foam. On this heat insulation base 4, the soil layer 6 is laminated | stacked through the filter 5, and various plants are planted. Water passage grooves 4a and 4a are arranged in a lattice pattern on the surface of the heat insulating base 4, that is, the surface in contact with the soil layer 6 through the filter 5, and the drainage groove 4b on the back surface, that is, the surface in contact with the waterproof layer 2. 4b are arranged in a lattice shape, and the water flowing through the drainage grooves 4b flows down to a separate wastewater treatment mechanism (not shown).

上記従来の外断熱と屋上緑化の複合構造にあっては、上述のような構成を有することにより、客土層６における雨水、潅水の余剰分は通水溝4aを解して排水溝4bに至りここを流れて廃水処理機構に移動する。 このことは、防水層２を介してであるが下地１上を水が常に移動することを意味しており、この移動により下地１、防水層２における熱エネルギーが流水により外部へ移動廃棄されてしまい、折角断熱基盤４を使用した意味が損なわれることになる。   In the conventional combined structure of the outside heat insulation and the rooftop greening, by having the above-described configuration, the excess rainwater and irrigation water in the soil layer 6 passes through the water channel 4a and becomes the drainage channel 4b. It reaches here and moves to the wastewater treatment mechanism. This means that the water always moves on the base 1 through the waterproof layer 2, and this movement causes the thermal energy in the base 1 and the waterproof layer 2 to be moved and discarded to the outside by running water. Therefore, the meaning of using the folded heat insulating base 4 is impaired.

最良の実施形態Best Embodiment

植物の断熱植栽構造は、下地上に形成される防水層と、植物の毛根等の侵出を防止するために前記防水層上に固着張設されるルートガードと、ルートガード上に設けられる断熱基盤と、この断熱基盤上に積層される客土層と、前記断熱基盤と客土層との間に敷設されるフィルターとを具えて構成されるが、客土層には降水、潅水等により水が浸透する。その大部分は土壌中に保持されるがある量の水は土壌から下方の断熱基盤に滲出する。 この滲出水あるいは漏水に対する措置を講じておかないと、すなわち、断熱基盤への水の流出を確保しておかないと土壌中に過剰な水分が滞留して植物の根腐れ等の原因になる。   The heat insulating planting structure of the plant is provided on the root guard, a waterproof layer formed on the base, a root guard fixedly stretched on the waterproof layer in order to prevent the extruding of plant roots, etc. It comprises a heat insulation base, a guest soil layer stacked on the heat insulation base, and a filter laid between the heat insulation base and the customer soil layer. Water penetrates. Most of it is retained in the soil and a certain amount of water oozes out of the soil into the insulating base below. Unless measures are taken against this exudate or leakage, that is, unless the outflow of water to the heat insulation base is secured, excessive moisture will remain in the soil, causing plant root rot and the like.

そこで、本願発明では、断熱基盤に水を滞留させる蓄熱手段を設けて断熱基盤に流下する滲出水あるいは漏水に対処するようにしている。断熱基盤に流下した水をそこから外部に流したり、あるいはルートガード、防水層表面を通過させて外部に流出させると、すなわち常に水が移動できる状態におくと、その水は流れる過程で流域から熱を奪い外部に放出することになる。本願発明では、蓄熱手段により水を外部に流出させることなく接した箇所から収熱した状態で滞留させて断熱効果を挙げるようにしている。換言すれば、蓄熱手段はある種の断熱手段とも言うことができる。滞留水による補助断熱手段である。   Therefore, in the present invention, heat storage means for retaining water in the heat insulation base is provided to cope with exudation water or water leakage flowing down to the heat insulation base. If the water that has flowed down to the insulation base flows out of it or passes through the surface of the root guard or waterproof layer and flows out of the water, that is, if the water can always move, the water flows from the basin in the process of flowing. It takes heat away and releases it to the outside. In this invention, it is made to retain in the state collect | recovered from the location which contact | connected, without making water flow out outside by a thermal storage means, and it is trying to obtain the heat insulation effect. In other words, the heat storage means can also be called a kind of heat insulation means. It is an auxiliary heat insulation means by staying water.

蓄熱手段は、客土層、断熱基盤、ルートガード・防水層の間に形成される水の滞留経路で構成する。客土層からの滲出水あるいは漏水はその大部分が滞留経路に保持されて移動することがないから水の流出に熱交換したカロリーを外部に放出することがない。   The heat storage means is constituted by a water retention path formed between the soil layer, the heat insulation base, and the root guard / waterproof layer. Most of the exuded water or leaked water from the guest soil layer is retained in the retention path and does not move, so that calories that are heat-exchanged to the outflow of water are not released to the outside.

前記滞留経路の形態は種々可能であるが、断熱基盤の表面に複数形成され客土層からの漏水を受ける受水部と、これら受水部から溢れ出た水の保水部と、この保水部と断熱基盤底面との間に形成される細管とから構成し、受水部、保水部、細管に水を滞留させるようにする。 Although the form of the staying path can be various, a plurality of water receiving portions that are formed on the surface of the heat insulating base and receive water leakage from the soil layer, a water holding portion that overflows from these water receiving portions, and the water holding portion And a thin tube formed between the bottom surface of the heat insulating base and water is retained in the water receiving portion, the water retaining portion, and the thin tube.

滞留経路の構成に関しては、前記断熱基盤の表面には多数の突起部を形成して、前記受水部は突起部の頂部に形成した凹陥部により構成し、前記保水部は前記突起部間に形成される凹部により構成するとともに、この凹部と断熱基盤底面とを結ぶ細管により構成する。そして、断熱基盤底面には細管の各開口部を結ぶ溝部を形成する。 この溝部は、受水部、保水部、細管とともに滞留経路を構成することになり、ここに水の大部が滞留して、下地部からのルートガード、防水層を介して熱伝導により水への熱移転が生じるが水は滞留するため、熱が外部に放出されることはなく、下地以下の断熱効果が全うされることになる。 なお、断熱基盤は種々の断熱材により形成できるが、発泡スチロール等の汎用されている素材が好ましい。 Regarding the structure of the stay path, a large number of protrusions are formed on the surface of the heat insulation base, the water receiving part is formed by a recessed part formed at the top of the protrusion, and the water retaining part is between the protrusions. In addition to being formed by the formed recess, it is formed by a thin tube connecting the recess and the bottom surface of the heat insulating base. And the groove part which connects each opening part of a thin tube is formed in a heat insulation base bottom face. This groove portion constitutes a retention path together with the water receiving portion, the water retention portion, and the narrow tube, where most of the water stays here, and is transferred to the water by heat conduction through the root guard and the waterproof layer from the base portion. However, since water is retained, heat is not released to the outside, and the heat insulating effect below the base is achieved. In addition, although a heat insulation board | substrate can be formed with various heat insulating materials, the raw material currently used widely, such as a polystyrene foam, is preferable.

蓄熱手段としての前記滞留経路の容量には限りがあるから、大量の降雨に備えて客土層の囲繞壁等の上部から客土層および滞留経路の保持量を超える量の水を排水できるようにしておくことが望ましい。
したことを特徴とする断熱植栽構造。 なお、滞留経路における滞留水は、客土層の乾燥時にはフィルターを介して水分又は水蒸気として客土層へ還流する水分補給源となることがある。 Since the capacity of the staying path as a heat storage means is limited, in order to prepare for a large amount of rainfall, it is possible to drain water from the upper part of the surrounding wall of the guest soil layer in excess of the retained amount of the guest soil layer and staying path. It is desirable to keep it.
Insulated planting structure characterized by In addition, the staying water in the staying path may become a moisture supply source that returns to the soil layer as moisture or water vapor through a filter when the soil layer is dried.

発明の実施例Embodiment of the Invention

以下、この発明の実施例を図面に基づき説明する。 図１は、本願発明に係る断熱植栽構造の一実施例を示す一部切欠断面図である。
図において、２１はコンクリート下地、２２はコンクリート下地２１上に張設される防水層、２３は植物の毛根等の侵出を防止するために前記防水層２２上に固着張設されるルートガード、２４はルートガード３上に設けられる断熱基盤で、発泡スチロールなどの断熱材から形成されている。
この断熱基盤２４上にはフィルター２５を介して客土層２６が積層され種々の植物が植栽されるようになっている。 そして、前記断熱基盤２４の表面すなわちフィルター２５を介して客土層２６に接する面には、複数の突起２７，２７が形成されその頂部には凹陥部２８が形成されている。 そして、後述の図２に示すように、前記突起２７の周囲には凹部溝２９が格子状に形成されている。また、３０は、凹部溝２９底部と断熱基盤２４の底部を結ぶ細管で、断熱基盤２４の底面において開口しており、前記細管３０の各開口部を結んで断熱基盤２４の底部表面には格子状に形成された溝部３１が形成されている。 Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a partially cutaway cross-sectional view showing an embodiment of a heat-insulating planting structure according to the present invention.
In the figure, 21 is a concrete base, 22 is a waterproof layer stretched on the concrete base 21, 23 is a root guard fixedly stretched on the waterproof layer 22 in order to prevent the extruding of plant hair roots, Reference numeral 24 denotes a heat insulating base provided on the root guard 3 and is formed from a heat insulating material such as polystyrene foam.
On this heat insulation base 24, the soil layer 26 is laminated | stacked through the filter 25, and various plants are planted. A plurality of protrusions 27 and 27 are formed on the surface of the heat insulating base 24, that is, a surface in contact with the soil layer 26 through the filter 25, and a recess 28 is formed on the top. As shown in FIG. 2 described later, concave grooves 29 are formed in a lattice pattern around the protrusions 27. Reference numeral 30 denotes a narrow tube that connects the bottom of the recessed groove 29 and the bottom of the heat insulating base 24 and opens at the bottom surface of the heat insulating base 24, and connects each opening of the thin tube 30 to the bottom surface of the heat insulating base 24. The groove part 31 formed in a shape is formed.

図２は、前記断熱基盤２４の一部切欠斜視図である。前述のように、断熱基盤２４の表面には突起２７が多数形成されていて、結果として突起２７周りには凹部溝２９が格子状に形成されることになる。
突起２７の頂部には凹陥部２８が形成され、格子状に形成された凹部溝２９には多数の細管３０が形成され、凹部溝２９と断熱基盤２４の底部とを結んでいる。細管３０の上端は前記凹部溝２９に開口しており、下端は断熱基盤２４の底部表面で開口しており、底部表面の開口部は格子状に形成された溝部３１で結ばれている。 FIG. 2 is a partially cutaway perspective view of the heat insulation base 24. As described above, a large number of protrusions 27 are formed on the surface of the heat insulating base 24, and as a result, recessed grooves 29 are formed around the protrusions 27 in a lattice pattern.
A concave portion 28 is formed at the top of the protrusion 27, and a large number of thin tubes 30 are formed in the concave groove 29 formed in a lattice shape, and connects the concave groove 29 and the bottom of the heat insulating base 24. The upper end of the thin tube 30 is open to the recess groove 29, the lower end is opened on the bottom surface of the heat insulating base 24, and the opening on the bottom surface is connected by a groove 31 formed in a lattice shape.

上記実施例において、断熱基盤２４における蓄熱手段を構成する客土層からの漏水の滞留経路は、断熱基盤の表面に複数形成され客土層２６からの漏水を受ける受水部と、これら受水部から溢れ出た水の保水部と、この保水部と断熱基盤底面との間に形成される細管３０と、細管３０の下部開口端を断熱基盤２４底面において結ぶ溝部３１とから構成されている。 In the said Example, the retention path of the water leakage from the customer soil layer which comprises the thermal storage means in the heat insulation base 24 is formed in the surface of a heat insulation base, and the water receiving part which receives the water leak from the customer soil layer 26, and these water receiving A water retention part overflowing from the part, a narrow tube 30 formed between the water retention part and the bottom surface of the heat insulation base, and a groove 31 connecting the lower opening end of the thin tube 30 at the bottom surface of the heat insulation base 24. .

そして、該実施例において、受水部は、前記突起２７の頂部に形成される凹陥部２８により構成されている。 また、保水部は突起２７周りに格子状に形成される前記凹部溝２９により構成されている。
なお、突起２７の頂部に形成される前記凹陥部２８の開口部には、図３に示すように溢れ出る水の通路２８aを設ける場合がある。 In this embodiment, the water receiving portion is constituted by a recessed portion 28 formed at the top of the protrusion 27. Further, the water retaining portion is constituted by the concave grooves 29 formed in a lattice shape around the protrusions 27.
In addition, in the opening part of the said recessed part 28 formed in the top part of the processus | protrusion 27, as shown in FIG.

客土層２６における降雨、潅水の大部は客土層２６の土壌に吸収保持されるが余剰の一部はフィルター２５を通り断熱基盤２４に達する。 断熱基盤２４に達した余剰水は、まず突起２７の頂部における凹陥部２８に保持される。 まれに、余剰水の量が凹陥部２８に全量収容できない場合は、余剰水の一部は凹部溝２９に溢れ出て、その量が多いときは細管３０とこれに連通する溝部３１とによる空間に蓄積され外部に流出移動することなく滞留する。そして、突起２７の頂部における凹陥部２８、凹部溝２９、細管３０、溝部３１に収容される水は滞留して外部に移動することがないから、下地２１の熱も水を介して外部に放出されることがない。 すなわち、突起２７の頂部における凹陥部２８、凹部溝２９、細管３０、溝部３１およびこれに収納される水は、いわば蓄熱手段あるいは断熱基盤２４の断熱機能に取り込まれるあるいはこれと協働する断熱手段としての機能をはたすことになり、断熱基盤２４は雨水、潅水等により本来の断熱性能に影響を受けることがない。 Most of the rain and irrigation in the customer soil layer 26 is absorbed and held in the soil of the customer soil layer 26, but a part of the surplus passes through the filter 25 and reaches the heat insulation base 24. The surplus water that has reached the heat insulating base 24 is first held in the recessed portion 28 at the top of the protrusion 27. Rarely, when the amount of excess water cannot be accommodated in the recessed portion 28, a part of the excess water overflows into the recessed groove 29, and when the amount is large, the space is formed by the narrow tube 30 and the groove portion 31 communicating with this. It accumulates in the water and stays without flowing out. And since the water accommodated in the recessed part 28 in the top part of the protrusion 27, the recessed groove 29, the thin tube 30, and the groove part 31 stays and does not move to the outside, the heat of the base 21 is also released to the outside through the water. It will not be done. In other words, the recessed portion 28, the recessed groove 29, the narrow tube 30, the groove portion 31 and the water stored in the top of the protrusion 27 are taken into the heat storage means or the heat insulating function of the heat insulating base 24, or the heat insulating means that cooperates therewith. Thus, the heat insulation base 24 is not affected by the original heat insulation performance due to rain water, irrigation, or the like.
