Description

  The present invention relates to a greening system for roofs such as inclined roofs, flat roofs (rooftops), or folded-plate roofs using vine plants, and more particularly, greening of tin roofs, folded-plate roofs, slate roofs, etc. that have relatively low durability against loads. It is related with the greening system of a roof suitable for.

  In August 2001, due to the revision of the Urban Green Space Conservation Law, a greening facility maintenance plan certification system was established. In order to preserve and create a good environment in the city, this greening facility maintenance plan certification system recognizes the greening facility maintenance plan on the rooftop of buildings, open spaces, and other outdoor greenery facilities, and is an exception to the taxation of property tax. The purpose is to take measures and promote greening in cities such as rooftop greening.

In detail, those who intend to maintain a greening facility on the site of a building in the district designated as a district that focuses on the promotion of greening (limited to rooftops, open spaces and other outdoor areas of the building) create a greening facility development plans described greening facilities Outline of certain criteria (site area 1000 m ² or more, greening of 20% or more, etc.) if appropriate, the certified this greening facility development plan municipal length can do.

  As a means for greening a conventional building, for example, Patent Documents 1 to 5 disclose a greening system that fixes vines such as cocoons on the outer wall surface and roof of a building. Hereinafter, these conventional greening systems will be briefly described.

  In the greening system of Patent Document 1, a through hole is formed in the outer wall surface of a building, and a soil container is disposed inside the building, and vines such as vines planted in the soil container are transferred from the through hole to the building. It was the structure which made it extend to the outer side of this and to fix to an outer wall surface or a roof.

  The greening system of Patent Document 2 includes a vegetation soil and a slow-acting fertilizer in a cylindrical or bowl-shaped container such as bamboo, and is composed of a concrete retaining wall or a natural bedrock by a pot planted in the vegetation soil. The wall was greened.

  The greening system of Patent Document 3 is a planting unit in which a cocoon is planted in a greening base material having an irrigation pipe for supplying water and nutrients and grown in a plastic greenhouse. It was attached to the wall surface, and then connected to a supply pipe for supplying moisture and nutrients to the irrigation pipe of the plant unit, and the entire plant unit was covered with an induction net for guiding the straw to the entire wall surface of the building.

  In the greening system of Patent Document 4, a long-eluting coking fertilizer and a trace element are mixed in a sheet in which plant fibers and a nonwoven fabric are bonded together, and a greening sheet is completed in house cultivation by vegetating cocoons in this. The greening sheet was constructed on the wall of the structure to make it green.

The greening system of Patent Document 5 includes a plurality of acrylic or ABS resin boxes, and these boxes are continuously combined in four directions to form a waterproof root-proof hydroponic tank. It was configured to green the city buildings.
JP 2006-121911 A JP 2003-27507 A JP 2000-300079 JP-A-10-98937 JP 2002-176850 A

  When planting facilities such as industrial plants where factories, warehouses, parking lots, etc. are constructed, it is considered preferable to plant roofs that are not used at all from the viewpoint of effective use of the site. However, folded roofs, slate roofs, or tin roofs are often used for roofs of factories, warehouses, parking lots, etc., and it is difficult to greenen these folded roofs using the conventional greening system described above. there were.

  That is, if it is going to green a folded-plate roof etc. by the tree planting system of patent documents 1-3, since the stem and leaf of a vine plant will be in direct contact with the folded-plate roof etc. which became high temperature by receiving sunlight. However, there was a problem that a favorable breeding environment could not be formed for vine plants.

  Moreover, since the greening system of patent document 4 is a structure which grows a vine on a sheet | seat, the grown stem and leaf do not contact a folded-plate roof directly, but the adventitious root (underground stem of a vine) Roots other than the roots generated from the roots pass through the sheet and reach the folded plate roof or the like, and the folded plate roof or the like deteriorates due to root acid or the like.

  Furthermore, since the greening system of patent document 5 becomes a structure which hydroponically cultivates the straw with the hydroponic tank made from an acrylic or ABS resin, the above two problems do not arise, but a plurality of hydroponic tanks Must be continuously combined in four directions and installed on the roof, and there is a problem that the folded roof with a relatively low durability cannot be constructed because the weight is too large.

  The present invention has been made in view of the above problems, and can protect the roof from deterioration without imposing a burden on the roof, and can quickly green the roof in a short period of time. An object of the present invention is to provide a roof greening system that can effectively use the site of the facility while increasing the greening area, and can contribute to the prevention of global warming.

  In order to achieve the above object, a roof greening system according to the present invention is a roof greening system using vine plants, which is installed on a planter section for planting the roots of the vine plants, and on the roof of a building. A land portion for fixing the elongated stem of the vine plant, and the planter portion includes at least a waterproof container body and main culture soil accommodated in the container body, and The land portion includes at least a support frame that is placed or fixed on the roof and that forms a ventilation path between the land and the roof, and a growth net that is mounted on the support frame. .

  According to such a configuration, without placing a planter part containing the main culture soil in the container body on the roof, the burden is placed on the roof by the light vine plant stem and leaf part, the growing net, and the support frame. It can be green without hanging.

  In particular, according to the present invention, a tin roof, a folded plate roof, a slate roof or the like having a relatively low durability against a load can be greened, and a factory, a warehouse, a parking lot, or the like equipped with these roofs has been constructed. In facilities such as industrial plants, it is possible to effectively use the site while increasing the greening area.

  In addition, the vine plant grows relatively fast (about 3 to 5 mm per year if ex. Persimmon), so it can quickly cover the roof with a stem and leaves in a short period of time, and the vines can be greened. The covered roof is protected from direct sunlight, rain, etc., and its deterioration is reduced, and the temperature rise in the building equipped with this roof can be reduced.

  Furthermore, since a ventilation path is formed between the vine plant and the roof by the support frame, for example, when the greening system is provided on a metal roof such as a folded-plate roof or a tin roof, these metal The roof made of heat can dissipate heat by ventilation and form a good growing environment for vines. In particular, in the case of a folded plate roof, a sufficiently wide ventilation path is formed by the total of the interval formed by the support frame and the interval formed by the continuous uneven shape of the folded plate roof. Can be effectively dissipated.

  Here, the “roof” widely includes various forms or materials such as an inclined roof, a flat roof (rooftop), a folded-plate roof, a slate roof, a tin roof, and the like. The roof of the form or material can be greened.

  The “vine plant” includes a wide variety of plants such as pods, morning glory, wisteria, roses, and the like that anchor the elongated stalks to the growing net, for example, by the stems themselves, curly mushrooms, stabs, cocoons, suckers, roots, and the like.

  The "support frame" is made of metal or synthetic resin with excellent corrosion resistance, which can form a space in the vertical direction (including the slanted vertical direction in the case of an inclined roof) between the roof and the growing net. A frame structure is widely included. For example, a lattice structure in which a pair of upper and lower frame bodies extending in the horizontal direction with respect to the roof are connected by bundle pillars in the vertical direction with respect to the roof is used as a frame structure assembled on the four sides and the center of the roof. it can. The support frame is preferably as light as possible from the viewpoint of not placing a burden on the roof.

  The “growth net” is for fixing stems and leaves of vines and holding a growth sheet and a root prevention sheet described later. The material of the net is preferably one that has little expansion and contraction due to heat and does not deteriorate due to long-term use. For example, it can be formed of polyester fiber or resin. Further, from the viewpoint of weight reduction, the net stitches should be appropriately sized, and the warp member and weft member should be the minimum number necessary.

  The “main culture soil” includes a wide range of natural soil alone or soil obtained by mixing fertilizer, humus, lime, etc. at a certain ratio. In addition, “main culture soil” for growing the roots of vine plants (roots generated from the rhizomes) and “subculture soil” described later for growing the adventitious roots of vine plants (roots other than the fixed roots) Is only a primary and secondary relationship for convenience, and both are similar culture soils.

  Preferably, the land portion includes a water-impermeable root-proof sheet laid on the support frame, and a growth sheet made of fibers having water retention properties provided on the root-proof sheet.

  According to such a configuration, the adventitious root generated from the stem of the vine plant can be fixed on the growing sheet, and the adventitious root can be grown by the water stored in the growing sheet. In addition, the non-permeability of the root-proof sheet can protect the roof from rainwater, and can prevent vine plants from eroding the adventitious root roof.

  Here, the “root-proof sheet” is considered to be capable of preventing root erosion at the same time as long as it has water impermeability. For example, a sheet material made of synthetic resin, a synthetic fiber, or a natural fiber weave Various sheet materials that are impermeable to water and do not pass through the roots of vines are widely included, such as a sheet material obtained by coating a cloth or a nonwoven fabric with a synthetic resin material. For example, a sheet material obtained by coating a polyester fiber woven fabric with a polyester resin is less stretchable by heat, has high durability, and is suitable for a root-proof sheet.

  The “growing sheet” includes a wide range of woven or non-woven fabrics of synthetic fibers or natural fibers capable of storing moisture. For example, linen sheet material, which is a natural fiber fabric, not only has water retention but also has good adhesion to powders and granules such as subculture soil and fertilizer, which will be described later, and adversely affects vine plants and the surrounding environment. Does not affect. Furthermore, since hemp bags are widely used industrially, waste materials can be reused, which is suitable as a growing sheet.

  Preferably, the growing sheet of the land portion is formed in a bag shape, and the subculture soil is stored in the bag.

  According to such a structure, by making the growing sheet into a bag shape, the subculture soil can be favorably retained, and the outflow due to wind and rain of the subculture soil in the bag can be reduced. Moreover, when using the hemp bag mentioned above as a cultivation sheet, the hemp bag which is a waste material can be reused as it is, without processing anything. Therefore, it is low-cost, can be easily constructed without trouble, and can satisfy a public interest request for effective use of resources.

  Preferably, the roof is a folded plate roof or a slate roof, and a support frame of the land portion is fastened to a bolt for fixing the folded plate roof or the slate roof.

  According to such a configuration, a special part for fixing the support frame is not required, and the configuration can be simplified, the number of steps can be reduced by reducing the number of components, and the cost can be reduced. In addition, as described above, the folded plate roof or the slate roof that is frequently used in buildings of industrial plants can be greened without load with a very lightweight configuration, so increasing the greening area of such industrial plants, The site can be used effectively. Furthermore, as described above, in the case of the folded plate roof, a sufficiently wide ventilation path is formed in total of the interval formed by the support frame and the interval formed by the continuous uneven shape of the folded plate roof. The metal roof can effectively dissipate heat.

  Preferably, the planter part includes a heat insulating sheet interposed on the inner peripheral surface of the container body.

  According to such a configuration, the heat insulating sheet can reduce the influence of ambient temperature change and keep the inside of the planter part within a predetermined temperature range. It becomes possible to do. As the heat insulating sheet, a sheet material having a low thermal conductivity, for example, a vinyl sheet can be used.

  Preferably, the planter part is a water-insoluble and light-weight granular member housed under the main culture soil in the container body, and a water-permeable member interposed between the main culture soil and the granular member. And a filter member.

  According to such a configuration, the granular member can raise the main culture soil to reduce the weight of the planter part, and the granular member prevents the vine plant root (constant root) from extending in all directions. Without creating a good training environment. Further, the filter member is partitioned so that the main culture soil and the granular member are not mixed, and the granular member is prevented from floating and flowing out when a large amount of rainwater flows into the container body.

  Here, the granular member aims to raise the weight of the planter part by raising the main culture soil. Therefore, the “light weight” of the granular member means that the weight per unit area is lighter than at least the main culture soil. Further, as the “particulate member”, a water-insoluble natural or synthetic solid or hollow material can be used. For example, solid or hollow foamed plastic particles such as polystyrene foam are suitable. is there. Furthermore, as the “filter member”, for example, a woven or non-woven fabric of synthetic fibers or natural fibers can be used. When the filter member is a woven fabric, the texture should be small enough to substantially prevent passage of the main culture soil and the granular member.

  Preferably, the planter unit supports a growth frame having a side wall and a water-permeable bottom wall for storing the granular member in the container body, and supports the bottom wall of the growth frame to support the bottom part of the container body. And a pedestal frame that forms a space serving as a water retention layer.

  According to such a configuration, the granular member is accommodated in the growing frame, and the growing member is covered with the filter member so as to surround the granular member and prevent the floating and outflow more reliably. Further, the pedestal frame forms a water retaining layer by storing water that has passed through the main culture soil, the filter member, the granular member, and the bottom wall of the growth frame. This water retaining layer supplies water directly or indirectly to the roots (constant roots) of vine plants.

  Here, the “growing frame” is preferably made of a synthetic resin having a certain degree of strength and excellent corrosion resistance. The side wall and the bottom wall of the growing frame may be integrally formed. For example, only the bottom wall may be a separate synthetic resin or metal net and assembled to the side wall. Note that the mesh of the bottom wall may be smaller or larger than the granular member. When the mesh of the bottom wall is made smaller than the granular member, the water retaining layer formed by the pedestal frame is not filled with the granular member. Conversely, when the mesh of the bottom wall is made larger than the granular member, the water retaining layer is filled with the granular member.

  Preferably, a predetermined allowable water retention amount is set in the container main body of the planter unit, and a drain outlet is provided at a position corresponding to the water level of the allowable water retention amount in the container main body.

  According to such a configuration, excess water exceeding the allowable water holding capacity of the container body is discharged from the drain outlet, so that the allowable water holding capacity can be easily maintained, and the root of the vine plant can be easily configured. Rot can be prevented.

  Here, the “drainage port” is preferably provided at a position filled with the granular member, and as its form, for example, a hole intended to prevent the granular member from flowing out by a filter or the like, a plurality of holes smaller than the granular member, a hole Various forms such as one in which the drain pipe is connected to the pipe to control the direction of drainage are widely included.

  According to the roof greening system of the present invention, the roof can be protected from deterioration without imposing a burden on the roof, and the roof can be quickly greened in a short period of time, thereby increasing the greening area. In addition, the site of the facility can be used effectively, which can contribute to the prevention of global warming.

  Hereinafter, a roof greening system according to an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a perspective view showing a building in which a roof greening system according to an embodiment of the present invention is implemented. FIG. 2 is a cross-sectional view of the main part showing the greening system. FIG. 3 is a side cross-sectional view of a planter portion that constitutes the greening system. FIG. 4 is a perspective view showing a growing frame and a pedestal frame constituting the planter unit. FIG. 5 is an exploded perspective view of a land portion constituting the greening system. FIG. 6 is a plan view of a land portion constituting the greening system.

  1 and 2, reference numeral 1 denotes a greening system according to an embodiment of the present invention, which mainly includes a planter unit 10, a land unit 20, and a vine plant 30. The planter unit 10 is fixed to the upper end of the front wall of the building 100 by a bracket (not shown). On the other hand, the land portion 20 is installed on the folded plate roof 110 of the building 100. Then, vines 30 such as cocoons planted in the planter unit 10 grow, and the extended stems 32 and leaves 33 are fixed on the land unit 20.

<Description of the planter unit 10>
As shown in FIG. 3, the planter unit 10 has a configuration in which the exterior of the container body 12 is covered with an exterior member 11. Inside the container main body 12, the below-mentioned means 13-18 for growing the vine plant 30 (refer FIG.1 and FIG.2) are accommodated.

  The exterior member 11 is made of, for example, a lightweight decorative board, and preferably has various decorative designs that match the building 100. The exterior member 11 hides the appearance of the container body 12 made of a bag-shaped water-resistant sheet.

  The container body 12 is a bag-like member extending in the longitudinal direction having a substantially U-shaped cross section formed of a water-resistant sheet obtained by impregnating synthetic fibers with rubber. A frame (not shown) is attached to the inside of the container body 12 to maintain the flexible container body 12 in a predetermined container shape.

  Further, a simple heat insulating sheet 13 such as a vinyl sheet is interposed on the inner surface of the container main body 12 to prevent heat transfer inside and outside the container main body 12. Thereby, the temperature in the container main body 12 can be set to a low temperature in summer and a high temperature in winter as compared with the outside air, which is good for growing the roots 31 of the vine plant 30 (see FIG. 2, the same applies hereinafter). It forms a comfortable temperature environment.

  Further, inside the heat insulating sheet 13 of the container main body 12, a growing frame 17 and a pedestal frame 18 that store the main culture soil 14, the filter member 15, and the granular member 16 are sequentially stacked from above. is there.

  The main culture soil 14 is soil in which fertilizer, humus soil, lime, and the like suitable for growing the vine plant 30 are mixed at a certain ratio. The composition of the main culture soil 14 is not particularly limited, and either natural or artificial soil can be used.

  The filter member 15 is divided so that the main culture soil 14 and the granular member 16 do not mix, and prevents the granular member 16 from floating and flowing out when a large amount of rainwater flows into the container body 12. It is. As such a filter member 15, for example, a non-woven fabric or a woven fabric having water permeability can be used while substantially preventing passage of the main culture soil 14 and the granular member 16.

  The granular member 16 is for raising the weight of the main culture soil 14 to reduce the weight of the planter unit 10, and is a water-insoluble material that is lighter in weight per unit area than at least the main culture soil 14. For example, it is made of expanded polystyrene particles. The fixed root 31 of the vine plant 30 planted in the main culture soil 14 described above passes through the filter member 15 as it grows, and reaches the granular member 16. The granular member 16 forms a good growing environment without preventing the constant root 31 from extending in all directions.

  Such a granular member 16 is housed in a square-shaped growth frame 17 as shown in FIG. The growing frame 17 is made of a synthetic resin that has a certain degree of strength to withstand the weight of the outer shell and the main culture soil 14 and is excellent in corrosion resistance. The bottom wall has a smaller diameter than the granular member 16. A large number of through holes 17a are formed. Water that has passed through the main culture soil 14, the filter member 15, and the granular member 16 is supplied to the pedestal frame 18 below the through holes 17 a. In addition, when accommodating the granular member 16 also in the base frame 18, you may make the diameter of the through-hole 17a of the growth frame 17 larger than the granular member 16. FIG.

  As shown in FIGS. 3 and 4, the pedestal frame 18 has a quadrangular shape having the same dimensions as the growth frame 17, and has a substantially C-shaped column 18 a that supports the bottom wall of the growth frame 17 at the center. Is standing. Such a pedestal frame 18 stores the water that has passed through the through holes 17a of the growth frame 17 and forms a water retention layer 18b. The water stored in the water retention layer 18b directly or evaporates and contributes to the growth of the fixed root 31 of the vine 30.

  Although not shown in the drawing, the pair of growth frames 17 and pedestal frames 18 described above are arranged side by side in the longitudinal direction inside the container body 12 and occupy almost the lower half of the volume of the container body 12. ing.

  Here, in the present embodiment, a predetermined allowable water retention amount is set in the container main body 12, and a drain port (drain pipe) 19 is provided at a position corresponding to the water level W (see FIG. 3) of the allowable water retention amount in the container main body 12. Is provided. The drain port 19 penetrates the exterior member 11, the container main body 12, and the heat insulating sheet 13 and communicates with the inside of the growing frame 17 that houses the granular member 16.

  Since the excess water exceeding the allowable water holding capacity of the container body 12 is discharged from the drain port 19, it becomes possible to easily maintain the allowable water holding capacity and prevent root decay of the vine plant 30 with an extremely simple configuration. can do.

<Description of the land part 20>
As shown in FIG. 5, the land portion 20 includes a plurality of support frames 21, 21, 21... In a lattice shape on the folded roof 110 of the building 100. The growing sheet 23 and the growing net 24 are stacked in order.

  The single support frame 21 has a lattice shape in which a pair of parallel frame bodies 21a, 21a are connected by a plurality of bundle pillars 21b, 21b, 21b,. In the present embodiment, the support frame 21 is made of steel and galvanized in order to have good corrosion resistance.

  When the steel material is galvanized, the cost of the support frame 21 can be reduced, but the support frame 21 may be formed of stainless steel or synthetic resin. Such a support frame 21 is preferably as light as possible from the viewpoint of not placing a burden on the folded plate roof 110.

  For example, as shown in FIG. 6, if the dimension of the folded roof 110 of the building 100 is 5 m × 5 m, the total length L1 of the single support frame 21 is set to 2.5 m, and each support frame 21 is set. The two are assembled with bolts so as to intersect each other at the four sides of the folded plate roof 110 and at the center thereof.

  In addition, as shown in FIG. 2, each support frame 21 and the folded plate roof 110 are fastened with a nut 112 to an extra length portion of a bolt 111 that connects the folded plates 110 a and 110 a constituting the folded plate roof 110. Yes (see enlarged view in FIG. 2). Thereby, the ventilation (25 cm) of the interval (25 cm), which is the sum of the interval formed by the support frame 21 (which substantially corresponds to the total length of the bundle column 21 b of approximately 10 cm) and the interval formed by the continuous uneven shape of the folded roof 110. A path F is formed below the root prevention sheet 22.

  Note that the L-shaped frame, which is the material of the frame body 21a, and the cylindrical pipe, which is the material of the bundle column 21b, are all general-purpose products, so the end materials or remaining materials of these L-shaped frame and cylindrical pipe are reused. Thus, the support frame 21 can be manufactured.

  Next, as shown in FIG. 2 and FIG. 5, the root-proof sheet 22 is coated with a non-permeable sheet material, for example, a synthetic resin sheet material, a synthetic fiber or a woven or non-woven fabric of natural fiber, with a synthetic resin material. The sheet material can be formed of various sheet materials that are impermeable to water and do not pass adventitious roots 32a grown from the elongated stem 32 of the vine plant 30 (see the enlarged view in FIG. 2).

  In the present embodiment, the root prevention sheet 22 is formed of a sheet material obtained by coating a polyester fiber fabric with a polyester resin. Such a root-preventing sheet 22 has high durability because it has less water expansion and contraction, in addition to good water permeability and blocking ability of the indefinite root 32a.

  Further, a plurality of eyelet fittings 22a, 22a, 22a... Are attached to the four sides of the root prevention sheet 22 at a predetermined interval, and a string (not shown) is passed through these eyelet fittings 22a and tied to the frame body 21a of the support frame 21. Thus, the root prevention sheet 22 is stretched on the support frame 21.

  The growing sheets 23, 23, 23... Are made of a woven or non-woven fabric of synthetic fibers or natural fibers that can store moisture. In the present embodiment, hemp bags that have been used for other purposes are reused as they are as the growing sheets 23. In each growing sheet 23, a small amount of subculture soil 23a for growing adventitious roots 32a grown from the stem 32 of the vine plant 30 is put. The subculture soil 23a has the same components as the main culture soil 14 described above.

  The growth sheet 23 made of hemp, which is a natural fiber fabric, not only has water retention, but also has good adhesion to powders or granular materials such as subculture soil 23a and fertilizer, and adversely affects the vine plant 30 and the surrounding environment. There is no effect. Furthermore, since hemp bags are widely used in industry, it is possible to reuse waste materials.

  The growth net 24 is for fixing the extended stem 32 and the leaf 33 of the vine plant 30 and holding down the growth sheet 23 and the root prevention sheet 22 described above. The material of the growing net 24 is preferably a material that does not expand and contract due to heat and does not deteriorate with long-term use, and can be formed of, for example, polyester fiber or resin. Further, from the viewpoint of weight reduction, the stitches of the growing net 24 should be appropriately sized, and the warp member and the weft member should be the minimum necessary number.

  Further, a plurality of eyelet fittings 24a, 24a, 24a,... Are attached to the four sides of the growing net 24 at predetermined intervals, and a string (not shown) is passed through these eyelet fittings 24a and tied to the frame body 21a of the support frame 21. Thus, the growing net 24 is stretched on the support frame 21. Note that the same string may be passed through the eyelet fitting 24a and the eyelet fitting 22a, and the growing net 24 and the root prevention sheet 22 may be connected to the frame body 21a and stretched together.

<Action and effect>
According to the roof tree planting system 1 according to the present embodiment described above, when the vine plant 30 planted in the planter unit 10 grows, the stem 32 and the leaf 33 grow by entwining a curly mushroom, a sucker or an adventitious root (not shown). It can be fixed on the net 24 and the entire folded plate roof 110 of the building 100 can be greened.

  Further, according to the roof greening system 1 according to the present embodiment, the relatively heavy weight planter portion 10 is not provided on the folded plate roof 110, and only the lighter land portion 20 is placed on the folded plate roof 110. Therefore, greening can be performed without placing a burden on the folded-plate roof 110 having relatively low durability. Thereby, in facilities, such as an industrial plant in which buildings 100, such as a factory, a warehouse, and a parking lot, equipped with folded-plate roof 110 were constructed, the site can be effectively used while increasing the greening area.

  Further, since the vine plant 30 grows relatively quickly, it can be quickly greened by covering the folded plate roof 110 with the stem 32 and the leaf 33 in a short period of time, and the folded plate roof covered with the stem 32 and the leaf 33. 110 is protected from direct sunlight, rain, etc., and its deterioration is reduced, and the temperature rise in the building 100 can be reduced.

  Furthermore, since the ventilation path F is formed by the support frame 21 between the vine plant 30 and the folded-plate roof 110, the metal folded-plate roof 110 is radiated by the wind passing through the ventilation path F, and the vine plant is radiated. 30 good growth environments can be formed. In particular, in the case of the folded plate roof 110, a sufficiently wide ventilation path F is formed in total of the interval formed by the support frame 21 and the interval formed by the continuous uneven shape of the folded plate roof 110. The metal folded plate roof 110 can be radiated effectively.

  In addition, the adventitious root 32 a generated from the stem 32 of the vine plant 30 can be fixed on the growing sheet 23, and the adventitious root 32 a can be grown with the moisture stored in the growing sheet 23. Further, the non-permeable nature of the root-preventing sheet 22 can protect the folded-plate roof 110 from rainwater, and also prevents erosion of the indefinite root 32a of the vine plant 30 on the folded-plate roof 110, thereby folding the folded plate with root acid. Deterioration of the roof 110 can be prevented.

  Furthermore, according to the roof greening system according to the present embodiment, since the end material, the remaining material, or the waste material can be reused for the support frame 21 and the growing sheet 23, it is low-cost and can be easily and easily constructed.
