Description

The present invention relates to a wall surface greening device. In particular, the present invention relates to the structure of a wall surface greening device that can shield a building from direct sunlight and improve the landscape of the building by arranging planters in which plants are planted vertically and horizontally along the wall surface of the building.

In recent years, wall greening in which plants are planted on the outer wall of a building has been attracting attention as it helps to alleviate the heat island phenomenon and save energy. In addition, by arranging plants along the outer wall of the building, it is possible to improve the landscape of the urban area where there are few natural trees. For such wall greening, various construction methods such as climbing type, hanging type, auxiliary material type, and unit type have been proposed or implemented.

In the climbing type wall greening method, the wall surface of a building can be greened by allowing vines having adhering roots that can freely adhere to the wall surface to climb independently on the wall surface. The climbing wall greening method has the advantage of being able to green at low cost, but has the limitation that it is limited to adherent plants with attached roots.

In the hanging wall greening method, the wall of a building can be greened by hanging plants along the wall from a planter installed on the rooftop or veranda. In the auxiliary material type wall greening method, the wall surface of a building can be greened by climbing or hanging a vine using an auxiliary material such as a wire. In the unit-type wall greening method, the wall surface of the building can be greened by arranging units such as planters in which plants are planted vertically and horizontally along the wall surface of the building.

Wall greening tends to be required for buildings built in urban areas. Buildings constructed in urban areas tend to be placed at positions where their outer wall surfaces are close to adjacent land boundaries or road boundaries. For this reason, a method of greening the outer wall surface by a hanging type or an auxiliary material type is generally adopted. However, such a greening method has management problems such as restrictions on the type of plant, restrictions on the water supply method, restrictions on the nutrient supply method, and difficulty in exchanging plants.

On the other hand, the unit-type wall greening method has a feature that there are relatively few restrictions on the types of plants to be planted in planters and the like. In addition, the unit-type wall greening method has the advantage that it is easy to automate irrigation and the like, and even if some plants are depleted, the landscape can be maintained by replacing the planter that cultivated the plants.

In such a unit-type wall greening method, it is a wall greening device in which planters planted with plants are arranged vertically and horizontally along the wall of the building, and it is possible to prevent the water to be irrigated from becoming uneven at each stage. At the same time, a wall surface greening device capable of preventing the planter on the lower stage side from becoming excessively humid than the planter on the upper stage side is disclosed (see, for example, Patent Document 1).

Further, in such a unit-type wall greening method, a semi-gutter-shaped planter is arranged vertically and horizontally on the surface of a panel that can be attached to the wall of a building, and a water guiding structure that guides the water accumulated in the upper planter to the lower planter is provided. A wall surface greening device provided at appropriate intervals in the longitudinal direction of a panel is disclosed (see, for example, Patent Document 2).

When the internal planter 81 is housed in the external planter 82 with reference to FIG. 7, the bottom corner of the internal planter 81 abuts on the inner wall of the slope wall 82s, so that the bottom of the internal planter 81 comes from the bottom surface of the external planter 82. The internal planter 81 can be placed at a distance.

Referring to FIG. 7 or FIG. 9, the external planter 82 has a water storage unit 821 at the bottom capable of storing water Wa. The other piece 85b of the water guide member 85 is immersed in the water Wa of the water storage unit 821. The water Wa of the water storage unit 821 can be guided to the potting soil Sf via the water guide member 85.

Referring to FIG. 7, the external planter 82 fixes the angle member 822 to the rear wall 82b. On the other hand, referring to FIG. 9, a plurality of angle members 823 are fixed to the wall surface We of the building. By mounting the angle member 822 on the angle member 823 and fixing the angle member 822 to the angle member 823 with a bolt member, a plurality of external planters 82 can be arranged in multiple stages in the height direction along the wall surface We of the building. (See FIG. 8).

Referring to FIG. 8, the external planter 82 is provided with a water level maintenance pipe 83 at the end. The water level maintenance pipe 83 can drain the water Wa when the water Wa stored in the water storage unit 821 reaches a predetermined water level or higher. The water level maintenance pipe 83 is connected to the guide pipe 83p. When the water Wa stored in the water storage unit 821 reaches a predetermined water level or higher, the water Wa can be guided from the upper external planter 82 to the lower external planter 82.

Referring to FIG. 8, the wall surface greening device 8 has a water supply pipe 84 arranged at the upper part. A solenoid valve 84v is provided in the middle of the water supply pipe 84. By opening the solenoid valve 84v, water Wa can be supplied to the external planter 82 at the uppermost stage.

Further, referring to FIG. 8, in the wall surface greening device 8, the water level sensor 86s is arranged inside the outermost planter 82 at the lowermost stage. The water level sensor 86s and the solenoid valve 84v are connected by a wire cord 86c.

When the water level sensor 86s detects that the water level of the water storage unit 821 is 1 cm or less with reference to FIG. 7 or FIG. 8, the solenoid valve 84v opens and water supply from the water supply pipe 84 is started.

Next, the configuration of the wall surface greening device according to another embodiment of the prior art will be described. Referring to FIG. 9, the wall surface greening device 80 according to another embodiment connects the rain chain 83c to the water level maintenance pipe 83 instead of the guide pipe 83p shown in FIG.

Referring to FIG. 9, the rain chain 83c has its upper end moored to the water level maintenance pipe 83. Further, the lower end of the rain chain 83c hangs down toward the water storage portion 821 of the lower external planter 82. As a result, water Wa can be guided from the upper external planter 82 to the lower external planter 82 via the rain chain 83c. The rain chain 83c disclosed in the other examples is peculiar to Japanese architecture, and the beauty of the ring can add color to the building.

In the wall surface greening device by the conventional technique, when a certain amount of water is stored in the water storage part of the external planter until the water level of the water stored in the water storage part exceeds the predetermined height, and the water level exceeds the predetermined height. Is sequentially guided to the water storage section of the external planter on the lower stage, so by arranging multiple external planters in multiple stages in the height direction, the amount of water stored in the external planter of each stage becomes uneven. It is said that it can be prevented.

Further, since the wall surface greening device by the conventional technique is equipped with a water guiding member capable of guiding the water stored in the water storage part to the soil of the internal planter, the soil of the internal planter on the lower stage is excessive than the soil of the internal planter on the upper stage. It is said that it can prevent the condition from becoming damp.

However, referring to FIGS. 7 to 9, the wall surface greening device according to Patent Document 1 depends on the nutrients of the potting soil Sf contained in the internal planter 81 in order to grow the plant P. The wall surface greening device according to the prior art can sufficiently supply water for growing the plant P, but there is a concern that nutrients will be insufficient in order for the plant P to continue to grow. Further, if nutrients are absorbed and consumed by the upper planters, there is a risk that the plant P will grow differently in the upper and lower planters.

In a wall greening device in which planters planted with plants are arranged vertically and horizontally along the wall surface of the building, it is possible to circulate water containing nutrients necessary for the plants to grow, that is, a culture solution. preferable. In this case, referring to FIG. 9, it is conceivable to circulate the culture solution supplied from the drip tube to the culture soil of the upper planter through the rain chain 83c to the soil of the lower planter. If the gutter 83c is contaminated, there is a concern that the landscape of the wall surface greening device will be spoiled.

In the wall surface greening device configured to circulate the culture solution, a drainage pipe extending in the horizontal direction is essential to collect the excess culture solution discharged from the bottom of the planter, but this horizontal drainage pipe is a plastic pipe. If the plastic pipes are arranged so that they can be seen from the outside, there is a concern that the landscape of the wall surface greening device will be spoiled. There is a demand for a wall surface greening device that is configured to circulate the culture solution and can improve the design.

FIG. 10 is a front view showing the configuration of a wall surface greening device according to another conventional technique. FIG. 11 is a plan view showing the configuration of a wall surface greening device according to another conventional technique. FIG. 12 is a vertical cross-sectional view showing the configuration of a wall surface greening device according to another conventional technique. It should be noted that FIGS. 10 to 12 of the present application correspond to FIGS. 1 to 3 of Patent Document 2.

Referring to FIGS. 10-12, another prior art wall greening device 9 includes a rectangular panel plate 91 and a pair of semi-gutter-shaped planters 92/92.
