Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to greening of all artificial structures, and more particularly to a greening unit for guiding greening of a place where waterproofing is required, such as a roof surface, and a method of constructing the greening unit. Things.

[0002]

2. Description of the Related Art As urbanization progresses, concrete construction and reinforcement work has been increasing not only from houses to large buildings, but also river revetments, roads, parks, and the like. In recent years, greening has been called out from the viewpoint of the landscape and the environment, and construction for the purpose of greening is being actively carried out. The present inventor has already filed Japanese Patent Application Nos. 10-33807 and 10-156.
579 proposes a thin layer greening method. In the above proposal, by combining extremely strong plants with strong drying and culture medium materials incorporating a strong grid-like plate, we provide independent panels that are not particular about the surface to be greened, and are lightweight and simplify construction. We have been providing systems that use measurable nets.

[0003] In the stand-alone panel, taking advantage of the characteristic that plants to be used hardly require soil and water, by incorporating a plate for tensile strength roots, it is necessary to stick to the shape and material of the target surface. There is a feature that it can be installed without any need, and the range of greening objects has been greatly expanded.
However, since the installation method is a method of joining panels of the same size and finishing it, it is suitable for greening a certain area, but if it is used for a large area, the work of connecting and fixing will increase and the cost will increase. Therefore, it was not suitable for a wide range of greening. The net-using system uses two continuous nets, and the method of finishing the plant by uniformly sandwiching the plants between the nets simplifies both production and construction. Was useful. Since this net system is not a stand-alone type, it is necessary to separately provide a layer of artificial soil or porous concrete that allows roots to enter on the surface to be greened. There were also issues such as the need for labor.

[0004]

SUMMARY OF THE INVENTION The present invention relies on the labor required for constructing a large area in a previously developed stand-alone ultra-thin greening panel, artificial soil and porous concrete in a thin-layer greening net system. We will pursue the issues of the construction method and efficiently handle a wide area while being independent. In addition, the present invention provides a completely independent type of greening unit that enables construction without being affected by environmental conditions and seasons, thereby expanding the range of use, and furthermore, the invention itself has a fixed function.

[0005]

In order to achieve the above object, the present invention provides a growth base which is lightweight and compact, yet retains water and drains itself, and has both tensile strength and adhesive strength. Use In addition, as an epoch-making method that eliminates the need for soil, the propagation material of the plant is wrapped in a mat and made independent as a green plant. Select the plants that can be used in harsh environments. Furthermore, an adhesion layer is attached to the growth base to form a growth base, and a separate and unnecessary tool for connecting and fixing is not required, so that simple and accurate construction can be performed. A thin-layer unit having the required functions with a simple structure as described above.

[0006]

BEST MODE FOR CARRYING OUT THE INVENTION As shown in FIG. 1, in the present invention, a green plant 5 in which a propagation material of the plant is covered with a mat having air permeability and water retention property is provided on an upper part, and a growth base 1 is provided on a lower part. In combination with a growth base 4 composed of a mat 2 and an adhesive layer 3 which are easy to obtain. The growth base 4 and the green plant 5 are produced and stored in different places, respectively, and the growth base 4 and the green plant 5 required at the construction site or the cultivation site are combined.

[0007] The growth base is formed integrally from the growth base to the adhesive layer. The adhesive layer has its own adhesive strength, and the waterproof layer adheres to a mat which easily obtains adhesive strength by using an additional adhesive. The mat which is easy to obtain the adhesive strength is fixed to the growth base by metal fittings such as sewing or stapling.

[0008] As one of the growth bases having a water retention / drainage function which leads the present invention to a stand-alone type, a plurality of mats having water retention / drainage combined in consideration of the environment of the installation place are sewn or glued. One mat is used by fixing with a metal fitting such as a stapler. In consideration of the work efficiency of transportation, the width of the growth base is 1 m, and the weight of one roll is 2
It should be around 0kg.

A non-woven fabric which is inexpensive and available in large quantities is used as a material for the mat which needs a water retention function and a drainage function. Artificial fibers such as polyester, polyethylene, polypropylene, and rayon, and natural fiber materials such as coconut fiber, cotton, wool, hemp, and pulp can be used. Water retention required for woven fabric, asbestos, sponge, rock wool, etc.
The material is not particularly limited as long as it has a drainage function and can be processed into a planar shape. Use them properly depending on the situation of the place of use and the type of plant used. In the case of a nonwoven fabric, thin fibers are used for producing a mat having a water retention function, and thick fibers are used for a mat having a drainage function. If large voids are created with thick fibers and solidified with resin or adhesive, a mat having high drainage power can be obtained. As the thread or metal fitting to be sewn, use a material such as polyethylene or stainless steel which is stable for a long time and can obtain strength.

A water retention agent, a water retention material, or a fertilizer can be incorporated into or between the mats used for the growth base, and a growth base having a thin layer and sufficient moisture holding ability can be obtained.

When the installation location is a flat surface or a slope of 5 ° or less, the growth base is basically composed of a mat having a water retaining function on the upper part and a mat having a drainage function on the lower part. In order to avoid this, the effects of environmental conditions such as sunshine conditions, wind power, and rainfall shall be fully taken into consideration, and drainage materials shall be separately incorporated as necessary. Drainage power is increased on slopes and vertical surfaces of 30 ° or more, so it is necessary to retain moisture as much as possible. The growth base shall be composed of a mat that has a water retention function on both the top and bottom, avoiding a mat that has a drainage function. Further, in order to guide the roots of the plant downward, that is, to the target surface, and to create stable vegetation, a lower mat similar to the upper mat or one having a higher water retention capacity is used. It is also possible to incorporate a water retention material / water retention agent separately.
On an inclined surface of 5 ° or more, one mat having a water retention function can be used as a growth base.

As the water retaining material, a light soil cultivation having high water retaining ability such as peat moss, coco dust, vermiculite, etc. is used. Incorporate between mats of greenery or from the manufacturing stage of the mat. As will be described later, in the present invention, it is necessary to eliminate as much as possible fine powdery materials such as buried soil in order to adopt a construction method using an adhesive layer. If there is a risk of the soil spilling, the whole is hardened with water-soluble glue. Moreover, what processed the said cultivation soil into a small block or a mat shape is used. The small block compresses the cultivated soil to form a sphere or cube,
The surface should be covered with a water-soluble glue or covered with a net. Utilizing water-soluble glue, it can be processed into mats instead of small blocks. In the case of a mat shape, a net having a tensile strength for easy handling can be incorporated at the same time. A high molecular polymer is used as the water retention agent. Incorporate solid and organic fertilizers as needed.

As another growth base, one mat having both water retention and drainage functions can be used. A nonwoven fabric made of a combination of fibers having different water holding powers, a combination of fibers having different thicknesses, or a nonwoven fabric composed of a group of water retention balls 8 as shown in FIG. 2 is also promising. The water retention ball 8 serves as a water retention layer, and the gap serves as a drainage layer 9 through which excess moisture flows down. The water retention ball 8 is made of a small block processed from the peat moss, coco dust, vermiculite, or the like, or made of fine fiber cotton or low denier rayon processed into a spherical shape. For 9, a thick polyethylene fiber or the like is used. Water retention agents and solid fertilizers can be incorporated during the manufacturing process. FIG. 2 is a sectional view of the growth base 1 using a plurality of mats and a single mat.

If necessary, a mat or net having a reinforcing function is incorporated in the growth base. In the case of a multi-mat growth base, either
Between the upper and lower mats, or below the lower mat,
Alternatively, they may be incorporated in both. When incorporated below the lower mat, the mat also becomes easy to obtain the adhesion described later, and a single sheet has the function of reinforcing and fixing the adhesive layer. In the case of a single mat, it is incorporated inside during the manufacturing process. Mats having a reinforcing function provide the growth base with resistance to various weather conditions and tensile strength.

The material of the mat or net having a reinforcing function is preferably stable for a long period of time, although it depends on the gradient of the target surface and environmental conditions such as wind force, and polyester, polyethylene, polypropylene and the like can be applied. When using on steep slopes, it is necessary to guide the roots downward, and use a material that allows the roots to pass through.

[0016] Since the present invention is a fixing method using an adhesive layer, dust or powder at the construction site causes a reduction in the effectiveness of the adhesive layer or the adhesive. It is also effective to prevent the generation of dust and the like by covering the surface of the growth base of the plurality of mats and the single mat with a water-soluble glue which does not hinder the growth of the plant.

The mat located under the growth base and having good adhesive strength functions effectively for providing an adhesive layer. It plays a role in securely attaching an adhesive layer that is difficult to adhere to the growth base made of a nonwoven fabric and a waterproof layer that should avoid making holes as much as possible to the growth base. As the material of the mat, a material having a long-term stability, such as strong polyethylene or polypropylene, is used, and also serves as a reinforcing material for enhancing the tensile strength of the present invention. It also has the function of protecting the adhesive layer and the waterproof layer.

The adhesive layer provided at the bottom has four main types. FIG. 3 shows a partial adhesive layer in which an adhesive layer is partially disposed. For the adhesive layer 3, a tape-shaped double-sided pressure-sensitive adhesive sheet is used. There are two methods for mounting the double-sided adhesive sheet as shown in FIG. An adhesive layer 3 having a width of 10 to 15 cm is attached to a growth base 1 to which a mat 2 which easily obtains an adhesive strength is fixed, by about 50 c
Attach every m. Conversely, width 1m on both sides of 1m width and center
It is provided in a band shape at 0 to 15 cm. In the case of connection, it is possible to connect firmly because the one attached in a band shape uses the entire adhesive portion. When used on an inclined surface, if a drainage gap is made as shown in the figure, it can be placed vertically or horizontally. Use the method appropriate for the environment of the installation site. In both cases, a drainage layer is provided in a space formed between the partial adhesive layers, and is used particularly in a place where a drainage function is required.

The entire surface adhesive layer having an adhesive layer on the entire surface is attached to the entire surface using a double-sided pressure-sensitive adhesive sheet. Steep slopes and strong winds
Use in harsh environments that are prone to wind and rain. At least one side of the adhesive layer is protruded about 10 cm in order to secure a connection portion in both the partial adhesive layer and the entire adhesive layer. A sticking prevention sheet 11 is provided on the surface of the adhesive layer 3 to facilitate handling. When sticking on the target surface, as shown in FIG. 4, the sticking prevention sheet 11 is fixed while being peeled off.

A waterproof double-sided pressure-sensitive adhesive sheet having a waterproof function is used for the waterproof overall adhesive layer. Since the waterproof double-sided pressure-sensitive adhesive sheet having sufficient adhesive strength has elasticity, even if there is a difference in expansion force between the invention itself and the material of the target surface, it does not affect the adhesive force. The present invention having a waterproof type full-surface adhesive layer has a feature as a mat for lucrativeness having a waterproof function by itself. Used when greening places where waterproofing equipment is required, such as rooftops, to save the labor of waterproofing equipment construction. In particular, when a waterproof function is required, a separate waterproof layer is provided or an adhesive layer formed by stacking a plurality of waterproof layers is provided under the present invention at the time of construction.

As an adhesive layer, a waterproof layer 16 and a separate adhesive 7
Has the same effect as the waterproof type full-surface adhesive layer. The waterproof layer 16 is made of a high-density material, and the adhesive 7 increases its effectiveness. In consideration of waterproofing, at least one side of the waterproofing layer 16 extends about 10 cm from the growth base 1 like the adhesive layer, and is used for connection between inventions. As shown in FIG. 5, the entirety of the invention connected by using the waterproof layer 16 with the adhesive 7 is further fixed to the target surface with the adhesive 7. The above-mentioned method enables construction with reduced costs. In addition, this method is used on a greening target surface which cannot be fixed with an adhesive, such as soil, even though it needs to be waterproof. The present invention having a waterproof layer can also be applied to a waterproof layer of an industrial waste disposal plant or a alien substance growing on a plant such as a strongly acidic soil. A waterproof sheet that is easy to handle can be used for the waterproof layer.

There is also a method of separately fixing only the growth base from which the adhesive layer has been removed from the growth base and the mat which is easy to obtain an adhesive strength with an adhesive. It utilizes the strength of the mat and can be used when a waterproof layer is separately provided or when there is no need for waterproofing, and cost reduction is expected.

FIG. 6 is a cross-sectional view of a working example of a growth base having a whole surface adhesive layer and a waterproof type whole surface adhesive layer. At least one side of the adhesive layer 3 protrudes about 10 cm from the growth base 1, and when connecting and fixing the present invention, peel off the sticking prevention sheet 11 of the adhesive layer 3 on the extra part, and remove another sheet. While peeling off the sticking prevention sheet 11 of the bottom surface of the present invention,
Connect it on top of it. Extra adhesive layer 3
One side serves as a connector, and at the same time, prevents water from leaking and dust from the connected portion, and prevents root invasion.

The following relates to the green plant located at the top of the present invention. The plant is characterized by having resistance to severe conditions such as drying, low temperature, and high temperature, but when subjected to a severe environment for a certain period of time, the plant itself becomes extremely strong against the environmental pressure. Many crassulaceae, such as the periwinkle and the Mexican nightcrop, fall into a dormant state as a method of withstanding environmental pressure.
At the same time, make small buds near the ground. Small buds are also dormant. Shown below are the structures and breeding methods for green plants that take full advantage of the tough nature of the dormant plants and small buds produced in harsh environments.

As shown in FIG. 7, the propagation material 1 of the plant
The dormant plants or small buds produced under the harsh environment, which are referred to as No. 4, are replaced with a mat 12 having air permeability and water retention.
Then, what was covered from above and below and wound in a roll shape is referred to as a green body 5. The air-permeable and water-retentive mat 12 is substantially in the form of a pad, so that it is preferable to incorporate one net 13 in order to facilitate the handling during winding and spreading. Net 13 also provides tensile strength. The width of the roll is the same as the growth base. Considering the transport work, the standard is 20kg unit, but it should be the same as the length of the growth base. The mat used for the upper part is preferably a mat having a hole through which the plant comes out at the time of growth or a material that can be easily penetrated. Cotton, hemp, rayon, pulp, etc. are applied to the mat. Absorbent cotton is preferable because it ensures high air permeability required during storage when dried, and high water retention required for plant survival when wet without water repellency.

The green plant is characterized in that it can be stored in a roll for a long period of time and that it grows well under severe conditions after construction. The installation time is not limited because it can be installed in a harsh environment such as a rooftop or the like, which is always exposed to direct sunlight, wind and rain, in midsummer or midwinter, which is almost impossible.

By utilizing the strong fertility of the plant or the small bud that is dormant in a harsh environment or the bud newly generated from the plant, instead of the mat as a material for covering the green plant. It is also possible to use a net with a small water retention capacity. The dormant plant and small buds are covered from above and below with a 6mm cotton net.
In an experiment set up on the growth substrate, it was found that small buds and buds newly generated from the plant grew well under the net and grew and covered the entire surface in 6 months. Water-retaining cotton nets offer the convenience and cost savings commonly available.

The method of covering the green body with a mat has the advantage that the surface to be installed is not stained or wet, and is most suitable for the present invention using an adhesive layer. In addition, seedlings of propagation materials should not be washed away by rain and wind.Also, the transpiration from plants should be suppressed and appropriate water content should be maintained, so that the plants will be able to survive and grow at an early stage. There are advantages such as being able to be efficiently performed between them.

It is also possible to cover the mat with a small seedling having the foliage of the plant in an active stage and a cultivated soil in the active stage, which have rooted in another place, to form a green plant. By having rooted and having soil, the appearance of dead plants can be minimized. Although the storage period is about several weeks because of the active plant, there is an advantage that the growth is fast and a high coverage can be obtained in a short period of time. It can be used for construction that requires short-term production and early greening.

Small seedlings 15 having cultivation are prepared on a plate 18 having a large number of cells. The plate 18 may be made its own, but generally used plates are used because the size and arrangement of cells correspond to the seeder.
It is particularly useful when a seeding machine is used in combination. The generally used plate 18 has about 10,000 to 20,000 cells per 1 m ^{2, and although} it varies depending on the plant to be cultivated, 10,000 to 20,000 cells are used.
Ten thousand seedlings are produced. When a green plant 5 is produced using a small seedling 15 having a cultivation soil, a green plant corresponding to about 15 m ² is produced from a seedling made from a 1 m ² plate. Adjusted by the density that requires 15 m ² a guideline. As shown in FIG. 8, the paper tape 17 may be used to form a chain.

In order to root the foliage of the plant, the foliage is extremely resistant to drying. The foliage of the plant is lined up on the surface of the cultivated soil in a place that is not exposed to much wind, and the root is rooted. it can. Those that have passed for two months have firm roots and a high survival rate, but those with about two weeks can be used satisfactorily.

The green plant can be cultivated in advance. By cultivating, it is expected that a high coverage will be obtained early.

The following are the experimental results supporting the relationship between the green plant and the environmental pressure. In the experiment, the scorpion family Sedum sp. The experimental materials were a small seedling A with cultivation in the active phase, a small seedling B with cultivation in the dormant phase under severe conditions, foliage C of the plant in the active phase, and cultivation in the active phase. Seedling D having no seedling, and seedling E having no cultivated soil in a dormant period under severe conditions. Prepare what is grown on the farm and what is not, and put one on the rooftop.
Left for years. A, B, C, D and E all showed good growth on the farm prepared for the experiment.

As a result of the experiment, it was found that A, B, C, D, and E all grew on the roof even when cultivated on the farm. As for those not cultivated, A, B, D, and E could grow, but those that grew reliably in midsummer and midwinter were B.
And E only. C foliage not grown on the farm almost died. Further, regarding the storage in a place where the temperature is low, B and E were not damaged even after one year, and the others were damaged in about two weeks.

From the above results, B and E, which grow without difficulty under any conditions such as long-term storage, cultivation, and severe conditions, that is, the presence of the plant or small seedling in a dormant state generated in a harsh environment, In the present invention utilizing vegetative propagation, to enable long-term storage and minimize dead plants,
It can be said to be a breakthrough that enables efficient production. The use of non-cultivated B and E is the most reliable and the most cost-effective. However, when the amount of green is desired early or at an event site where flowering is desired from the beginning of construction, this can be realized by using a green plant cultivated in another place.

To cultivate the green plant, a watering facility is used in another place, and sufficient water is given to supplement the water retention function. It is also possible to combine the green plant and the growth base at the cultivation site, which are usually performed at the construction site, and to transport the integrated product to the installation site. The growth substrate stores moisture and entangles the roots of the plant that the green plant has, so that only rainwater or simple irrigation is enough to save the labor of management. In addition, early growth is anticipated, and because the green plant and the growth base have already been integrated, there is no temporary decline in growth due to changes in the environment after construction, and the roots have survived and strong winds Don't worry about being skipped.

When a green plant or a green plant integrated with a growth base is cultivated in another place in advance, it is necessary that the green plant is not contaminated as much as possible. Therefore, it is better to cultivate after laying a plastic film or the like. By finishing the green body without dirt and dust, the work of removing the dirt at the installation location can be omitted and the work can be performed efficiently. Inexpensive agricultural mulching sheets can be applied to plastic films.

It is necessary to pay attention to dirt and moisture on the surface to be installed, especially in construction that also serves as waterproofing. By hardening the green body with water-soluble glue or glue such as vinyl acetate, the generation of dust is prevented. In an experiment in which the plant was covered with a water-soluble spray paste to cover the green plant, no dust or other obstacles were generated, and it also prevented the decomposition of the green plant and the loss of plants. The plants also showed almost normal growth. However, when the water-soluble glue is used, the storage stability deteriorates.

The connection between the growth base and the green plant is made directly at the construction site, but may be integrated in advance at the green plant cultivation site as described above. Although the roots of the green plants grow and entangle with the growth base, they are tightly bound. To temporarily fix the roots until they are firmly established, use a stapler or other metal fittings.
FIG. 9 shows a schematic diagram in the case of construction on a rooftop.

Since the growth substrate and the green plant are produced independently of each other, they can be used for applications utilizing their respective characteristics. For example, Japanese Patent Application No. Hei 10 (1994), which has a structure in which the plant is sandwiched between two upper and lower nets developed by the present inventors.
If the net system for thinning and greening is arranged on the above-mentioned growth base body, the net system can be reduced in cost and a simple construction method which does not require a fixture. In addition, the green plant can be installed on a growth base using a fixture, so that the soil is not required.

The plant which is extremely resistant to drought is
It is a succulent plant belonging to the family Crassulaceae, Oxalis, Cruciferae, Lily. In particular, there are many useful ones in the genus Sedum and the genus Ginseng.

The plant grows with an amount of water that can hold soil of 2 cm or less where most plants cannot grow. In order to increase the number of applied plants, it is absolutely necessary to increase the amount of water that can be held. Peat moss, coco dust, vermiculite, etc., which have high water retention ability and are used as a water retention material, are used for the growth base of the vertical surface or steeply inclined surface. The cultivation may be made into small blocks as described above. Light-weight soil with high water retention is extremely thin in the dry state, but increases its capacity and weight when it contains moisture.
It is lightweight and, after construction, gains capacity and weight to enable stable fixing.

As a method of expanding the width of the plant applied to the present invention, there is also a method of taking the form of a small seedling having the above-mentioned soil. It was considered difficult to use Misebaya with pink flowers because rooting from foliage is poor, but it can be used by producing small seedlings with cultivated soil and incorporating it into the green plant of the present invention Becomes In an experiment in which the green plant was placed on a growth substrate, almost no dead plants were observed, and the result of early full-surface coating was obtained.

Incorporation of a lightweight soil with high water retention,
In addition, by adopting the form of small seedlings with cultivated soil, the types of the plants that can be used are widened, and it is possible to obtain the color and shape of the changing flower. Red, pink, and orange flowers, such as Misebaya, Matsubagiku, Matsubabotan, and Livingstone Daisy, are added to the flowers that used to be white and yellow before that, enabling more beautiful greening in design.

【The invention's effect】

Fixing with an adhesive, which previously required a complicated system, or fixing relying on anchors that inevitably pierce the target surface, can be achieved by providing an adhesive layer at the bottom to fix the greening target surface. It enables construction without drilling holes.
In particular, since the waterproof-type full-surface adhesive layer has a waterproof function, if it is applied to, for example, a roof surface, it becomes possible to perform greening at the same time as waterproofing, and the need for installation is expanded.

Since the present invention itself has the adhesive layer, almost no other connecting tool or fixing tool is required.

[0047] The problem of eliminating the gap and overlap at the time of connection / fixing and deciding the connection point and the fixing point was solved by providing an adhesive layer.

Since the green plant is covered with the mat, the effectiveness of the adhesive layer and the adhesive is not reduced, and the propagation material is not washed away by wind and rain. It is also a great advantage that the earth is not required.

A green plant using the dormant plant or small buds produced in a harsh environment enables long-term preservation, has a good plant viability, and is suitable for construction in harsh seasons such as midsummer and midwinter. Removed time restrictions.
