Wall greening panel and wall greening structure using it

The present invention is made bodywork detachably on the wall of a building, to a green wall structure using the same and green wall panel greening walls of different designs can be constructed.

Today, not only the rooftop of buildings but also the greening of walls is being proposed as a measure to improve the landscape and the so-called heat island phenomenon, and various techniques for greening the walls are being offered.
When the wall surface is greened, by reducing the amount of solar heat transmitted from the wall surface, it is possible to reduce the rising temperature of the living space configured inside the building and to reduce the cooling load. Therefore, realizing wall greening of the building contributes to mitigating the heat island phenomenon. In addition, the greening of the wall gives a natural harmony by changing the inorganic wall surface to a human-friendly landscape.

As an example of wall greening technology, a net having a lattice of about 10 cm formed of a metal material or the like is attached away from the wall surface, and a wire or the like is provided along the net in a vertical direction to climb a vine plant. It was. In this case, since the plant support is a wire that stands upright with the grid-like net, there was a significant limitation on plants having climbability.

Another wall greening technology is a system that directly attaches a mat made of sheet metal such as coconut shell fiber and a metal net to the wall surface to vegetate vine plants and attached root type plants. Problems, such as property, mat coloration, wall air permeability, and wall surface contamination.

Furthermore, a method of greening a vertical wall surface by arranging a base made of felt or non-woven fabric on the wall surface and planting a plant seedling therein is adopted. However, with this method, the plant planted on the base grows almost parallel to the ground, so when the plant grows, the base is deformed by the weight of the plant and the force the plant receives from the wind. There is also a risk that the plant will peel off from the base.

  Furthermore, a method has been proposed in which a pocket is formed in a substrate made of a plastic material, and a plant grown in a pot is placed in this pocket. In this proposal, the pocket is inclined so that the plant grows slightly upward with respect to the ground. However, since plant roots can only grow in pockets, large plant growth cannot be expected. In addition, it is necessary to irrigate each pocket with a predetermined frequency during the dry season when there is little rainfall.

Moreover, a wall surface greening technique is also disclosed in which a pocket is provided in a planting panel that is locked to a wall surface and has a water retention / absorption means on the back surface, and plants in the pocket are grown by the water retention / absorption means. However, with this technique, there is a problem that the moisture in the water retention / absorption means is unevenly distributed in the lower part due to the influence of gravity and does not spread evenly to the roots of the plant, and the removal and transfer of the panel is not easy.

The technology related to the present invention is disclosed in the following document.

May be configured .

In the wall panel of paragraph 0012 , a plurality of the through grooves may be formed in a U shape.

In the wall greening panel of paragraph 0011, the plant root holding part is constituted by a plurality of planting mats arranged side by side with a gap in the vertical direction, and the moisture uneven distribution preventing means is constituted by a gap between the plurality of planting mats. In some cases, the gap space is dropped from the lower end of the upper planting mat toward the upper end of the next planting mat .

Moreover, in any one of the wall surface greening panels, the planting mat may be formed of a nonwoven fabric.

In the wall greening panel according to paragraph 0015, the nonwoven fabric may be a mixture of a cotton material and a synthetic fiber material.

The present invention also includes a wall greening panel detachably mounted on a wall surface, and irrigation means installed at an upper end of the wall greening panel, wherein the wall greening panel is configured as described in any one of paragraphs 0010 to 0016. In order to solve the above-described conventional problems, a wall surface greening structure including the above is provided.

Further, in the wall surface greening structure described in paragraph 0017, a plurality of wall surface greening panels are installed, and the side end portions of the wall surface greening panels adjacent in the horizontal direction are joined so that the plant root holding portions of the respective wall greening panels communicate with each other. The plant root planted in the pocket part may be configured to advance to a plant root holding part that communicates.

Furthermore, the wall surface greening structure according to paragraph 0017 or 0018, wherein the irrigation means is a perforated hose that drops water on the plant root holding part.

Still further, the present invention provides a wall greening panel according to any one of paragraphs 0010 to 0016, wherein the wall greening panel is locked to a wall surface so that the plant root holding portion of each wall greening panel is in contact with and communicates with the wall greening panel. A wall greening structure is provided in which irrigation means is provided and water is supplied to the entire wall greening panel by diffusing each plant root holding part communicating with water supplied from the irrigation means by contact as a water channel.

In the wall surface greening structure described in paragraph 0020, the plant root planted in the pocket portion may be advanced into the plant root holding portion between the wall surface greening panels communicating in the horizontal direction.

The present invention has the following effects.
(1) The wall surface can be greened quickly and easily inside and outside the building.
(2) Since large-scale construction is not required, installation cost, management cost or removal cost is low.
(3) Each wall surface greening panel can be attached to and detached from the wall surface, and various design configurations of the greening surface can be easily and freely made according to the location and time of day, such as the entire wall surface being greened or scattered. The removal of the green surface is also easy.
(4) Although the structure of the irrigation means is very simple, plants can be properly grown with a small amount of water supply.

The wall greening panel is made of a metal material or a resin material for both the front panel and the back panel, and the pocket provided in the front panel may be formed integrally with the front panel by injection molding or an opening formed in the front panel. You may attach the pocket part formed separately in the periphery.
Since the pocket portion holds the root portion of the plant, the shape thereof is various such as a rod shape, a truncated cone shape, and a cylindrical shape.

The plant root holding part interposed between the above-mentioned front and back panels is composed of a planting mat formed of a water absorbing / water holding material. This planting mat is provided with water unevenness preventing means for preventing water from being unevenly distributed between the upper part and the lower part due to gravity. That is, when the planting mat is formed of a water-absorbing / water-holding material such as sponge or non-woven fabric, water in the water-absorbing / water-holding material is easily accumulated in a large amount in the lower part due to the influence of gravity, and is unevenly distributed at the top and bottom. In order to prevent this uneven distribution and supply water uniformly to the plant roots, a water uneven distribution preventing means is required.

  This moisture uneven distribution prevention means is constituted by, for example, U-shaped through-grooves drilled in the horizontal direction in the planting mat, and if this is scattered, the water supplied at the upper part of the planting mat absorbs and retains water. The inside of the material moves to the through groove, and the movement is blocked by the through groove and stays in the vicinity of the through groove. If the staying amount exceeds a predetermined amount, the water drops from the upper side of the through groove and falls to the lower side opposite thereto, and then permeates and diffuses into the subsequent water absorption / water retention material. In this way, uneven distribution of moisture is prevented.

The moisture uneven distribution preventing means can also be configured as follows. That is, the plant root holding part is constituted by a plurality of planting mats arranged side by side with a gap in the vertical direction, and the moisture uneven distribution preventing means is constituted by a gap between the plurality of planting mats. Moisture that has reached the lower end of the upper-side planting mat once stops the transfer here, but when the retention amount reaches a predetermined amount or more, the moisture drops into the next-stage planting mat by dropping the gap , It penetrates and diffuses into the water-absorbing and water-holding materials that make up the planting mat in the next stage . In this way, uneven distribution of moisture is prevented.

Water absorption / water retention materials that make up the planting mat can be made of various materials such as resin water absorption materials, but non-woven fabrics can easily control the water retention rate by changing the moisture penetration rate and the laminated thickness of the nonwoven fabric. From this point, it is preferable.

If the non-woven fabric is composed of a mixture of cotton and synthetic fiber, the water supply and water retention can be controlled more precisely. That is, cotton is excellent in the penetration of moisture in the horizontal direction, and synthetic fiber is quick in draining and excellent in form maintenance.

A wall greening structure is configured by locking a predetermined number of the above-mentioned wall greening panels to the wall of the building so as to be detachable. And the irrigation means is installed in the upper end of the wall surface greening panel. This irrigation means is composed of a perforated hose that is connected to a water supply source and drops water onto the plant root holding part.

A plurality of wall greening panels are installed in the horizontal direction, and by joining the side edges of adjacent wall greening panels, the plant root holding part of each wall greening panel is communicated and planted in the pocket part If the root is connected to the plant root holding part, the rooting of the plant becomes good, which is preferable for the growth of the plant.

Water may be supplied to each wall greening panel directly from the perforated hose as the irrigation means, but a plurality of wall greening panels are connected to the wall surface so that the plant root holding part of each wall greening panel is in contact with and communicates with the wall greening panel. Lock and provide irrigation means on any one of the wall greening panels, and infiltrate and diffuse each plant root holding part that communicates the water supplied from this irrigation means by contact as a water channel. If water is supplied to the greening panel, the irrigation system can have a simple configuration.
