Description

  The present invention provides a building surface for greening a building surface such as a sound insulation wall of a road, a bridge pier, a bridge girder, a civil engineering building surface such as a slope after excavation of a dike or a natural ground, a building wall surface or a building building surface such as a rooftop. It is about tree planting method.

In general, methods that contribute to the reduction of the concentration of carbon dioxide in the atmosphere while greening the roof of the building to exhibit the effect of heating and cooling the building with natural plants are becoming widespread. In many cases, this type of conventional rooftop greening method for buildings is to build a space for accommodating planting soil on the roof with the rooftop floorboard, or arrange a planting container to replace this, and place the soil in the interior. A method of filling and greening by sowing or seedling planting is common (for example, Patent Documents 1 and 2). As this kind of rooftop greening plant, one using succulent plant sedum has been proposed.

  In addition, as a method for greening a rising surface or an inclined surface of a civil engineering building or a building, a method of creeping a vine plant is known. For the creeper plant, the use of a type with a sucker such as a nuts and a type with aerial roots or attached roots such as Hedera has been proposed, but it is porous to help climb the wall. A construction method has been proposed in which a climbing aid and a net-like protective material that prevents the climbing aid are attached to a wall surface (Patent Document 3).

  In the above-mentioned conventional rooftop and wall surface greening methods for building, the part where the soil is accommodated is constructed on site, and construction work such as waterproofing and protective mortar is required on the construction site such as the rooftop. In particular, on the rooftop or viaduct, it is not easy to carry in materials, and there are many cases where construction is difficult, and there is a problem that construction requires a long time.

Also, in the conventional method of using a container for planting, a container for planting is installed on the site, and a planting floor is formed by filling culture medium in it, and further sowing or planting seedlings. Therefore, there is a problem that the construction period is long and it takes a long time to complete the greening.

  In view of such conventional problems, the present invention was made for the purpose of providing a building surface revegetation method capable of installing a planting facility in the field in a short period of time and exhibiting a greening effect immediately after installation. It is.

The genus Hedera is used for the vine plant, and after the vine plant planted in the planting medium inside from the downward-facing recess extends to the outside of the planting container, the front, rear, left and right rising walls are placed on the planting container. It is to pile up the raising frame which does not have a baseplate, and to add the cultivation soil for planting in the raising part .

The feature of the invention described in claim 2 is that, in addition to the configuration of claim 1, the planting container has a bottom plate portion and front and rear, left and right rising walls each having a ridge shape having a number of through openings , The peripheral surface is covered with a sheet-like material that prevents the internal planting soil from being washed away, and the planting soil is filled inside.

In the building surface greening method according to the present invention, as described in claim 1, an upper open type box shape that can be stacked up and down in multiple stages is formed. in using a number of planting container with a breathable number of through openings, filled with planting soil containing water retention agent consisting of water-absorbing polymer and the porous material into the planting container, the In a building surface greening method in which a planting unit in which a vine plant is planted in a planting soil is installed on or near the surface of the building to be greened , the planting container has front, rear, left, and right rising walls. One or more of the above have a downwardly recessed part formed at a lower central part of the upper edge, so that the vine planted in the planting culture medium from the downwardly recessed part can extend out of the container for planting. The vine plant uses the genus Hedera Then, after the vine plant planted in the planting soil inside from the downward concave part extends outside the planting container, the raised frame having front and rear left and right rising walls and having no bottom plate is used as the planting container. It is layered on top, and additional soil for planting is applied to the raised part. A planting unit is filled with everything necessary for planting in the container for planting. Since the greening construction is completed by the work of transporting and arranging, the work man-hours at the construction site are small, the construction is completed in a short time, and even in the shade, greening is done, and the horizontal, vertical, All the inclined surfaces can be handled.

  Furthermore, after the planting work, water-absorbing polymers and porous materials are used for the cultivation soil, and after the first watering, the vine plant grows enough by hydration only with rainwater. When the fertilizer component is depleted over time, the cultivation frame and the fertilizer component can be easily added by using the raising frame, and the greening can be maintained semi-permanently at low cost.

  In addition, among the vines, by using the genus Hedera, such as Hedera helix, kizuta, etc., these are evergreen vines that grow by attaching to the trunk and wall of the tree at the air roots of the branches. Even if it piles up and fills culture soil and covers the part of the stalk, it does not die, and growth is promoted. Also, it is an evergreen plant that grows favorably in the shade, so it absorbs carbon dioxide and discharges oxygen through photosynthesis throughout the year.

  Embodiments of the present invention will be described with reference to the drawings.

The code | symbol 1 in the figure has shown the planting unit used for this invention. This planting unit 1 was planted in a planting container 2 in the shape of a flat basket, a sheet-like material 3 laid on the inner surface thereof, a planting soil 4 and a planting soil 4 filled therein. It is comprised from the vine plant 5.

As shown in FIGS. 2 to 4, the planting container 2 is formed in a rectangular flat plate shape, and the front and rear rising walls 11 and 11 and the left and right rising walls 12 and 12 are formed on the periphery of the rectangular bottom plate 10. The peripheral wall which consists of is formed integrally. The bottom plate 10 and the peripheral wall are integrally provided with reinforcing ribs 13 at various places, and flange-like edges 14 and 15 are integrally formed at the upper edge and the lower edge. A large number of window holes 16 penetrating and opening inside and outside are formed between the reinforcing ribs 13 and have air permeability and water permeability.

  The front and rear and the left and right rising walls 11 and 12 constituting the peripheral wall are formed with downwardly recessed portions 11a and 12a in which the upper edge of the central portion is lower than the corner portion.

Legs 17 that fit into the four corners of the upper open part of the planting container 2 are integrally formed at the four corners of the bottom surface, and these leg parts 17 are fitted into the openings of the planting container 2. As a result, the plurality of planting containers 2 and 2 can be stacked so as not to fall off. Moreover, this leg part 17 becomes a leg for forming the air permeable clearance under the container 2 for planting at the time of the installation mentioned later.

By stacking the plurality of planting containers 2 and 2 in this manner, the downwardly recessed portions 11a and 12a of the respective planting containers 2 are opened in the shape of windows.

The sheet-like material 3 is used to prevent the planting soil 4 filled therein from flowing out, and the inner wall side of the peripheral wall is preferably a non-permeable resin sheet to prevent drying. What is necessary is just a corrosion-resistant thing which has water permeability to the extent that the cultivation soil 4 does not flow out, such as fine synthetic resin woven fabric (mesh), sponge-like sheet material, non-woven fabric, porous sheet, etc. Can be used. These are laid down to the lower edge height of the downwardly recessed portions 11a, 12a in the planting container 2, and the cultivation soil 4 for planting is filled therein.

  The soil 4 for planting is a mixture of black soil, compost, peat moss, perlite, powdered or granular charcoal, and a water-absorbing polymer and porous material as a powdered or granular water retention agent, and various fertilizers as necessary. Use the one prepared by addition and mixing. As the water-absorbing polymer, a polymer that can absorb a large amount of water several hundred times to several thousand times the volume when dried and gradually discharge water is used.

  As the vine plant 5, a plant belonging to the genus Hedera, whose growth is vigorous even in the shade, such as Hedera helix, kizuta, etc., is used.

This planting unit 1 fills a planting container 2 with a sheet-like material 3 and a planting soil 4 in a plant or farm, and plantes a seedling of a vine plant 5 on the planting soil 4 to sprinkle water. After waiting for it to settle, it may be carried into the construction site, planting the seedlings of the vine plant 5, carrying it directly into the construction site without sprinkling water, installing it at a predetermined location and sprinkling it to root May be.

  Since conveyance to a construction site can be performed in the state which piled up a plurality of planting units 1 up and down, many conveyance can be made at once, without damaging a seedling.

The planting unit 1 having been planted in the planting container 2 in this way is installed by bringing it into the planting site and is grown so that the vine plant 5 grows on the planned planting surface. The example of installation of the planting unit 1 can be as follows, for example.

  That is, when the horizontal surface 20 such as the rooftop of a building is greened, the planting units 1 are simply arranged side by side with a predetermined interval on the rooftop floor board as shown in FIG.

  Further, when greening the wall surface 22 of a building or other building such as a vertically oriented surface or an inclined surface, the planting unit 1 is installed side by side on the front surface of the lower end of the wall surface 22 as shown in FIG. The plant 5 is greened by growing so as to grow upward while adhering to the wall surface. In addition, by installing the planting unit 1 on the upper side of the wall surface 22 such as the edge of the rooftop, the vine plant 5 grows so as to crawl downward from the upper side of the wall surface 22, thereby greening.

  As shown in FIG. 6, when the photovoltaic power generation panels 21 are installed side by side on the rooftop or on the concrete surface on the ground, they can be installed on the lower surface which is the shade, and the shade portion is thereby also reduced. Including rooftops and other horizontal parts.

Next, when the vine plant 5 grows to some extent, the fertilizer component of the planting soil 4 may be depleted. As a measure in that case, as shown in FIG. 7, the vine plant 5 is formed from the downward depressions 11a and 12a. The raising frame 25 is piled up in the container 2 for planting with the state which has crawled out. The sheet-like material 3 is installed on the inner peripheral surface of the raised frame 25, and the growth of the vine plant 5 is promoted by replenishing the fertilizer component together with the soil by filling the inside with a new soil 4 for planting. be able to.

In addition, although the raising frame 25 can use the thing of the shape which removed the bottom plate 10 part of the planting container 2 mentioned above as shown in FIG. 7, the shape which fits the opening part of the container 2 for planting other than this. Any other frame-shaped material may be used.

  In general, vines are broadly divided into adherent plants and rolled vines, and evergreen and deciduous trees. Adhesive plants climb plants directly on the outer wall without using auxiliary materials such as wires and nets. However, winding vines require auxiliary materials such as wires and nets to wind the plants.

  There are Hedera and Kizuta, etc., which are evergreens that absorb carbon dioxide by photosynthesis and exhale oxygen throughout the year.

  Considering the characteristics of these plants, the best plant for rooftop and wall greening is an adhering plant that climbs while adhering to the wall, is evergreen, has no problems with soil covering and topdressing from the leaves, dried, It is best to use the genus Hela, which is resistant to pests.

In addition, for permanent growth, there is a method of using a large amount of soil from the beginning using a planting container such as a large planter. However, a large amount of soil is not necessary for plant growth from the beginning. Depending on the growth, it is possible to add fertilizer with replenishment of soil using a raised frame as maintenance.

In this building surface greening method, the planting unit 1 in which everything necessary for planting is filled in the planting container 2 in advance is manufactured, and the planting is completed by transporting this to the planting site and arranging it. Therefore, the number of work steps at the construction site is small, the construction is completed in a short time, and even in the shade, greening is achieved, and all of the horizontal, vertical, and inclined surfaces can be handled.

Moreover, a planting unit can convey many by stacking what planted to the container for planting at once, and without damaging planting, and it can construct it at low cost.

  In general, roofs, columns such as bridges, columns such as sound insulation walls, and H-shaped steel collect rainwater around the columns when it rains. Even if it rains, the surface of the building around this waterway is in a wet state (water wetting phenomenon), which accelerates the early deterioration of the concrete structure. It leads to corrosion of reinforcing bars near the surface, expansion, cracks, peeling of concrete pieces, and damage to third parties. The concrete piece has been repaired by vinylon mesh, epoxy resin adhesive, and painting around the drainage at the bottom of the wall railing of concrete viaducts nationwide due to an easy accident, but it costs enormous construction costs such as scaffolding costs for repair.

  In this method, by placing the planting unit in the vicinity of the support column, it is possible to plant the vines of the genus Dela into the araliaceae while using the handrail as a climbing material. There is no water path, and the leaves of the genus Hempella genus repel rain to the outside, so there is no direct infiltration of water into the concrete due to rain, and the durability of the concrete structure can be improved.
