Description

The present invention relates to a rooftop greening facility for planting plants on a rooftop of a building or the like.

In recent years when global warming is said, the so-called heat island phenomenon in which the temperature in the center of a large city is several degrees higher than in the suburbs has become a problem. As a means for preventing this, it has been proposed to plant plants on the roof of a building. Known greening facilities include those that use lightweight soil, those that are thinly spread with gravel and that are non-irrigated, such as sedum, and those that increase the durability of the building and allow the culture soil to be thickened.

The rooftop planting facility using the light soil described above requires a considerably thick soil to plant trees so as not to fall down. Therefore, the soil unit price may be high, and it will be quite expensive. In addition, lightweight soil is easily blown away by the wind, and it also causes environmental deterioration around the building.

The rooftop greening facility using Sedum is light and inexpensive, but does not have the ability to cool the air in the rooftop environment.

A rooftop greening facility that puts the soil thickly increases the price per unit area and places a heavy burden on the building. Therefore, it can only be constructed in a new building, and the construction cost of that building will be expensive. Moreover, there is a limit to the durability structure, and the installation area of the greening facility cannot be increased so much.

The following requirements must be met when constructing rooftop greening facilities. In other words, it is light enough to green the entire rooftop of an existing building that has not been constructed with a durable structure, is inexpensive, and has a high ability to cool the air in the rooftop environment. Allow people to walk through the whole.

The present invention employs a vine plant that grows rapidly, the water intake changes day by day, and is difficult to manage artificially, and an automatic water supply device that is indispensable for water management of the plant. Thus, it is possible to cover a large portion of the rooftop area of the building despite the use of a flower pot that is relatively small and therefore requires a small amount of soil.

The shelf-type rooftop greening facility of the present invention is very lightweight because it suffices with a plant pot with a small amount of soil that occupies a small part of the rooftop area of the building. Never become. In addition, the flower pots need only be as small as the number of vines, and can be planted at a low price with a large area. In addition, despite the fact that vine plants that are difficult to control artificially because the water intake changes day by day, the cultivation soil in the flower pot is automatically maintained in a state of constant moisture. Water can be supplied. Furthermore, since shelves can be installed at a height that allows people to pass through, the upper part of the air conditioner and the like can be greened, and the maintenance of the air conditioner and the surroundings can be easily cleaned. When re-waterproofing the roof, the removal of the flower pot is easy and re-construction can be performed at a low cost. In addition, chairs and tables can be placed under the shelves to allow a wide space for relaxation. In addition, the wall surface can be greened by installing the shelf vertically.

When a perforated pipe is installed between the hole on the lower side of the automatic water level feeder and the drain on the side of the flower pot, drainage from the drain of the flower pot becomes easy, and air is supplied to the soil in the flower pot. Therefore, oxygen deficiency in the soil can be prevented, and the growth of the plant is extremely good despite the limited size of the flower pot.

The purpose of reducing the amount of soil used and greening the large area of the building was realized by adopting a constant water level automatic water supply device and vines, and placing the vines on shelves with props. .

FIG. 1 is a perspective view of an embodiment of a shelf-type rooftop greening facility according to the present invention, wherein 1 is a flower pot, 2 is a support, 3 is a shelf, and 4 is a vine plant. FIG. 2 is a vertical cross-sectional view of a flower pot part constituting the rooftop greening facility of the present invention.

The shelf-type rooftop greening facility of the present invention includes a flower pot 1, a constant water level automatic water supply device 5 accommodated inside the flower pot 1, a plurality of support columns 2, a shelf 3 attached to the upper part of the support column 2, and a flower pot 1. It consists of a vine plant 4 that is planted and spread on a shelf 3.

The flower pot 1 has a bottomed cylindrical shape or box shape whose bottom is a water reservoir, and the shape is not particularly limited. A drain port 1a is opened on the side surface opposite to the portion where the constant water level automatic water supply device 5 is placed. The material of the flower pot 1 may be anything as long as it does not exude water such as synthetic resin, ceramics, and metal. The flower pot 1 is sufficient in size to plant one vine 4. That is, it is not necessary to be large enough to cover a large part of the roof of the building, and may be relatively small. Therefore, less soil is used. The installation place of the flower pot 1 is a necessary place according to the four corners and the roof area of the building roof. In FIG. 1, six are placed.

The support 2 is erected in or around the flower pot 1. The support 2 supports the shelf 3 and guides the vine 4 to be planted in the flower pot 1 to the upper shelf 3. The number of the columns 2 is sufficient if it is the same as the number of the vine 4. In consideration of the weight of the plant to be sprinkled, it can be increased further.

The shelf 3 is a structure in which beams made of metal, wood, etc. are assembled vertically or horizontally on the upper part (upper end) of the support column 2, or the strength and durability network made of metal, fiber, etc. is removed from the upper end of the support column 2. The one attached so as not to be used is used.

The vine plant 4 is planted in the flower pot 1 and spread from the support 2 to the shelf 3. The types include wisteria, strawberry, loofah, cucumber, strawberry, akebi and the like. Since these vine plants 4 grow rapidly, they can cover a large part of the rooftop area of the building in a short time (period) despite the small number.

The constant water level automatic water supply apparatus 5 is accommodated in the flower pot 1 that is close to the side surface opposite to the side surface where the drain port 1a is provided. The structure includes a nozzle 7 having a water supply pipe 6 directly connected to a water supply or a water tank, a float 8, a needle 9 protruding from the float 8, and a needle 9 provided below the nozzle 7. The water outlet 14 of the nozzle 7 is blocked by the buoyancy of the float 8 when the water level 14 at the bottom of the flower pot 1 reaches a certain height. By employing such a constant water level automatic water supply device 5, water can be automatically supplied to the culture soil 12 placed in the flower pot 1 without requiring any electric power or manpower. Can be kept almost constant. Therefore, the optimal rooting state of the plant can be obtained, the growth is promoted, root rot and no chief are generated, no need for watering, no skill is required, and no fertilizer is lost due to watering . In addition, extra water such as rainwater is discharged from the drain outlet 1 a on the side surface of the flower pot 1.

The constant water level automatic water supply device 5 shown in the figure is merely an example, and any type may be used as long as the water outlet of the water supply pipe is closed by the buoyancy of the float. For example, there is a type in which float buoyancy used in an old flush toilet is transmitted to a ball tap (spherical valve) through an insulator and the outlet of the water supply pipe 6 is closed.

At the bottom of the flower pot 1, a porous tube 11 is provided that connects a hole 5 a provided in the lower side surface of the constant water level automatic water supply device 5 and a drain outlet 1 a on the side surface of the flower pot 1. The perforated tube 11 has many small holes all around. By arranging this porous tube 11, the water level 14 at the bottom of the flower pot 1 is maintained in the lower half of the porous tube 11, and the upper half is a cavity communicating with the drain port 1a. Therefore, not only drainage from the drainage port 1a is facilitated, but fresh air can be supplied to the culture soil 12 in the flower pot 1 through the small hole 11a of the perforated tube 11, thereby reducing oxygen deficiency in the soil. Can be prevented. Therefore, the plant growth is very good despite the limited size of the flower pot 1.

In the flower pot 1, the culture soil 12 is put, but before that, charcoal 13 having water absorption at a depth enough to fill the porous tube 11 is put at the bottom.

The shelf-type rooftop greening equipment configured in this way is a culture soil 12 placed on a layer of charcoal 13 in the flowerpot 1 keeps a certain moisture depending on its quality, but the plant takes moisture from the roots, When water evaporates from the surface of the culture soil 12, the water level 14 decreases accordingly. When the water level 14 is lowered, the float 8 is lowered, the outlet of the nozzle 7 is opened, and water is automatically supplied. In other words, the plant itself adjusts the water supply. Since the vine 4 grows rapidly and the water intake changes day by day, it is difficult and unsuitable for humans to adjust the water amount subjectively. Such a constant water level automatic water supply device 5 is optimal for supplying water to the vine 4.

The shelf-type rooftop greening facility of the present invention can be constructed on the rooftops of buildings in any area as well as buildings in large cities. In addition to being able to green the rooftop in a plane, it is also possible to green the wall surface by installing the shelves vertically.

It is a perspective view of 1 Example of the shelf type rooftop greening equipment of this invention. It is a longitudinal cross-sectional view of the flower pot part which comprises the shelf type rooftop greening equipment of this invention.
