Description

  The present invention relates to a greening curtain wall that is used as an outer wall of a building and greens a wall surface of the building.

  Conventionally, wall greening has been performed by planting the walls of buildings in order to mitigate heat island phenomena in urban areas, absorb carbon dioxide in the atmosphere, and create amenity spaces.

  And in this kind of wall greening system, for example, as disclosed in Patent Documents 1 to 3, a plurality of pipe-shaped planting units are hung along the wall of the building with a wire, and greening is performed. The soil foundation is housed in a plurality of boxes provided on the frame, and the frame is fixed to the wall of the building so that it is greened, or an ivy plant planted in the planting soil in the planter is provided above Some of them are grown while being supported on a net and are greened. Further, for example, as disclosed in Patent Document 4, a support member is fixed to the wall surface of a building, and a greening unit in which a cultivation base is inserted into a mesh frame formed in a bowl shape is hooked on the support member. There is also a wall greening system that installs and greens buildings.

  However, in the wall surface greening system disclosed in Patent Documents 1 to 3, in order to hang the planting unit from the roof, the degree of freedom of design is low, in order to install the unit type planting base on the frame built on the wall surface There are problems such as high cost and low degree of freedom in selecting plants for growing plants so as to cover the wall surface while being supported by a net installed on the wall surface.

  On the other hand, the wall surface greening system disclosed in Patent Document 4 can easily install the greening unit by hooking it on a support member, and has a high degree of freedom in design and plant selection. It is easy, and it is possible to flexibly cope with maintenance of buildings and wall greening systems (greening units). However, in this wall surface greening system including the wall surface greening system of Patent Documents 1 to 3, since the greening unit is installed separately from the exterior material (outer wall) of the building that has been built in advance, auxiliary materials for installation, etc. Cost.

On the other hand, for example, as disclosed in Patent Document 2 and Patent Document 5, a curtain wall (exterior panel) used as an outer wall (non-bearing wall) of a building such as a middle- or high-rise building is, for example, a box-shaped frame. In some cases, there is a soil base that is placed in a frame and a net that is fixedly attached to the frame and holds the soil base. In this greening curtain wall, it becomes possible to perform wall greening directly on the outer wall of the building, as compared with the case where the greening unit is installed separately from the conventional exterior material of the building. This eliminates the need for auxiliary materials for greening, thereby reducing costs.

  However, since the conventional greening curtain wall is configured to hold the cultivation base with a net installed on the surface side thereof, the plant grows greatly after being installed as the outer wall of the building, and the wall surface is plant. Until it was covered, the soil foundation was exposed as a wall surface, and there was a problem that it looked bad.

  In addition, when the greening curtain wall is exposed to wind and rain, the soil foundation may be deteriorated, and when the soil foundation is deteriorated as described above, the soil is dropped from the net of the net.

  Furthermore, because the soil foundation is simply held on the net, the soil foundation is easy to dry, rainwater cannot be actively taken into the soil foundation, and the water content is maintained so that the plant grows properly. In order to do so, there was a problem that the watering frequency to the soil foundation was required to be high.

  In view of the above circumstances, the present invention can improve the appearance until the plant grows, can prevent the soil from falling due to the deterioration of the soil foundation, prevent the soil foundation from drying and effectively use rainwater. It aims at providing the greening curtain wall which can reduce irrigation frequency aiming at.

  In order to achieve the above object, the present invention provides the following means.

  The greening curtain wall of the present invention comprises a soil base on which planting is performed, and a base holding member that is provided so as to cover the surface of the soil base disposed in the vertical direction and holds the soil base. A greening curtain wall used as an outer wall of a building, wherein the base holding member extends in a vertical direction, and is provided with a pair of vertical members respectively disposed on both sides of the soil base in the horizontal direction, and the pair of vertical walls. A plurality of cross members that extend in the horizontal direction by connecting both ends to the material and are arranged at predetermined intervals in the vertical direction, and the cross members are formed in a plate shape, and the soil base It is provided so that it may protrude outside from the surface side of this, and it is provided so that the other side edge part may be distribute | arranged upwards rather than the one side edge part of the surface side of the said soil foundation.

  In this invention, since the base holding member consisting of a pair of vertical members and a plurality of cross members arranged at predetermined intervals in the vertical direction is provided so as to cover the surface of the soil base, This foundation holding member can reliably hold the soil foundation and form the curtain wall.

  And since the cross member of this base | substrate holding member is formed in plate shape, it protrudes outside from the surface side of a cultivation base, and since the other side edge part is distribute | arranged upwards rather than one side edge part, it is provided. For example, since the cross member is provided so as to gradually incline upward from one side end to the other end, it is installed as an outer wall of the building, and the plant is greatly enlarged between the adjacent horizontal members up and down. Until it grows, when looking up from the bottom, the soil foundation is not visible, and the lower surfaces of the plurality of cross members are visible in a continuous state in the vertical direction. As a result, when the base holding member is made of a metal such as aluminum, an appearance as if a metal curtain wall is installed can be formed, compared with the case where a net is used as the base holding member. Thus, it is possible to improve the appearance until the plant grows large (until the wall is greened suitably).

  In addition, when the crossing material is provided as described above, even when the soil foundation is deteriorated, the dropped soil is retained by the crossing material, and the soil is dropped to the outside from the net of the net as in the past. Can be surely prevented.

  Further, by providing the cross member as described above, it becomes possible to positively take rainwater into the cultivated soil base side with the cross member at the time of rain. Moreover, since the surface of the cultivation base is covered with a plate-like cross member, drying of the cultivation base can be suppressed. Thereby, it is possible to easily maintain the cultivated soil base in a water-containing state suitable for the growth of the plant by the cross member, and to reduce the frequency of irrigation.

  In the greening curtain wall of the present invention, it is desirable that the cross member is connected to the vertical member so as to be rotatable and / or detachable about an axis extending in the horizontal direction.

  In the present invention, the cross member can be rotated to increase the gap between the cross members adjacent in the vertical direction, or the cross member can be removed. Thereby, even if it is a case where planting is carried out from the surface side to a cultivation foundation, it becomes possible to plant a cultivation foundation easily and suitably, without a crosspiece getting in the way.

  Furthermore, in the greening curtain wall of the present invention, a water storage portion having a concave cross section for temporarily storing water that has flowed from the upper end side of the soil foundation to the lower end side on the lower end side of the base holding member. It is more desirable that it is provided.

  In the present invention, for example, water supplied from an irrigation tube provided on the upper end portion side of the cultivating base and flowing down from the upper end side to the lower end side of the cultivating base can be temporarily stored by the water storage portion. As a result, it is possible to reliably prevent the soil foundation from drying, and to reduce the irrigation frequency to allow the plant to grow appropriately.

  Moreover, in the greening curtain wall of the present invention, it is further desirable that the cultivating base is provided with a water retaining part that temporarily retains the water supplied to the cultivating base from the upper end side on the upper end side. .

  In this invention, the water supplied to the cultivation base flows down from the upper end side to the lower end side, and the upper end side of the cultivation base is often in a dry state and the lower end side is in an overhumid state. By providing a water retention part that temporarily retains water on the upper end side of the soil, it is possible to prevent the upper end side of the soil foundation from becoming dry, and more reliably to maintain the moisture content of the soil foundation. It becomes possible to maintain in a state suitable for the growth of rice.

  Furthermore, in the greening curtain wall of the present invention, it is desirable that the base holding member is formed by applying a highly reflective paint on at least the surface of the cross member.

  In the present invention, since the highly reflective paint is applied to the surface of the base holding member, it is possible to prevent the soil base held by the base holding member from becoming excessively hot. As a result, it is possible to prevent the soil foundation from drying and to reduce the irrigation frequency so that the plant can be suitably grown.

  Further, in the greening curtain wall of the present invention, the base holding member is provided with a rain water introduction part for introducing rain water flowing down the joints extending in the vertical direction of adjacent curtain walls into the culture base. Is desirable.

  In this invention, generally, when the outer wall of a building is constructed with a curtain wall, a lot of rainwater will flow down the joints of the curtain wall adjacent to each other at the time of rainfall, but the rainwater flowing down the joints is used as a rainwater introduction part. By leading to the soil foundation, it will be possible to make more effective use of rainwater. Thereby, it is possible to easily maintain the cultivated soil base in a water-containing state suitable for the growth of the plant by the rainwater introduction part in addition to the cross member, and it becomes possible to reduce the irrigation frequency.

  According to the greening curtain wall of the present invention, a pair of vertical members, and a plurality of plate-like cross members provided such that the other side end portion is arranged above the one side end portion on the surface side of the cultivation base. It is possible to improve the appearance until the plant grows, to prevent the soil from falling due to deterioration of the soil foundation, and to prevent the soil foundation from drying. It is possible to reduce the frequency of irrigation by making effective use of rainwater.

  Hereinafter, with reference to FIGS. 1-5, the greening curtain wall which concerns on one Embodiment of this invention is demonstrated. This embodiment is installed as an outer wall (non-bearing wall) of a building by being attached to, for example, a marion (orientation) fixed to the outer periphery of a building across a plurality of floors or a fastener fixed to each floor. It is about greening curtain wall.

  As shown in FIGS. 1 to 4, the greening curtain wall A of the present embodiment covers the soil foundation 2 on which planting (plant 1) is applied and the surface 2a of the soil foundation 2 arranged in the vertical direction T1. And a base holding member 3 for holding the cultivating base 2 is provided.

  The soil foundation 2 includes, for example, heat-bonding fibers, and is formed in a square disk shape using heat-bonding soil (culture soil) that is solidified by heat treatment. The heat-sealing culture soil is a mixture of soil and inorganic foam (foam) such as pearlite and heat-fusible fibers. The heat-fusible fibers are bonded to each other by heat treatment, or fibers and foams, fibers. It is formed as a three-dimensional network structure by adhering to the soil. Thereby, soil is hold | maintained and the shape solidified is hold | maintained suitably. Further, the weight per unit volume of the inorganic foam is, for example, 0.5 kg / liter or less, and by mixing this inorganic foam, the heat-sealing culture soil and thus the soil foundation 2 can be reduced in weight. Appropriate water retention and drainage for the growth of 1 is given.

  Further, as shown in FIGS. 2 and 4, the cultivating base 2 is provided with an irrigation tube 4 on the upper end 2 b side, and the irrigation tube 4 supplies water W to the upper end 2 b side of the cultivating base 2. It is formed to be able to. Furthermore, in this embodiment, as shown in FIG.1 and FIG.2, the water retention part 5 is provided in the upper end part 2b side of the soil foundation 2, This water retention part 5 is the upper end part side of a heat-fusion culture soil, for example It is formed by adding a water-retaining material.

  On the other hand, the base | substrate holding member 3 of this embodiment is formed in the front view shape of the magnitude | size substantially the same as the soil-growing base | substrate 2, as shown in FIGS. And this base | substrate holding member 3 is extended in the up-down direction T1, and is equipped with a pair of vertical material 6 each arrange | positioned by the horizontal direction T2 both-sides edge part 2c, 2d side of the soil foundation 2, respectively, and both ends to a pair of vertical material 6 7a and 7b are connected to each other, and are provided with a plurality of cross members 7 that extend in the horizontal direction T2 and are arranged at predetermined intervals in the vertical direction T1.

  Each cross member 7 is formed in a flat plate shape and is provided so as to protrude outward from the surface 2 a side of the soil foundation 2. Further, each cross member 7 is arranged such that the other side end portion 7d is arranged higher than the one side end portion 7c on the surface 2a side of the cultivation base 2, that is, from the one side end portion 7c to the other side end portion 7d. It is provided so as to be gradually inclined upward as it goes to. Thereby, the board | substrate holding member 3 is formed in the shape of a louver.

  Moreover, in this embodiment, each cross member 7 is connected so that one end part 7a and the other end part 7b can rotate around an axis O1 extending in the horizontal direction T2 with respect to the vertical member 6. At this time, the axis O1 is arranged on the one side end 7c side of the cross member 7, and each cross member 7 is provided to rotate in the vertical direction T1 about the axis O1 on the one end 7c side by an appropriate means. ing. Further, the substrate holding member 3 is formed of a metal such as aluminum, for example, and is formed by applying a highly reflective paint on at least the surface (upper surface and lower surface) of the cross member 7.

  Moreover, as shown in FIG.1 and FIG.2, the bottom holding | maintenance member 3 is connected to the lower end part 3a side so that the lower end part of a pair of vertical material 6 may be connected, and the back surface side (horizontal side) of the base holding member 3 is shown. A water storage portion 10 having a concave cross section is provided so as to protrude outward from the one end portion 7 c side of the material 7.

  And the greening curtain wall A of this embodiment inserts the lower end part 2e side of the cultivation base 2 in the water storage part 10 of the foundation holding member 3, the cultivation foundation 2 is hold | maintained at the foundation holding member 3, and the cultivation foundation 2 of The surface 2 a is integrally formed so as to be covered with the substrate holding member 3.

  For example, as shown in FIG. 5, the greening curtain wall A is installed as an outer wall of a building by attaching the base holding member 3 outwardly to a marion or fastener (not shown) fixed to the outer periphery of the building. At this time, as shown in FIG. 5, the greening curtain wall A of the present embodiment includes a glass curtain wall (glass panel 11), a metal curtain wall (metal panel 12), a stone curtain wall (stone panel 13), and the like. It is attached to any position according to the design, such as the waist wall and pillar.

  Next, the operation and effect of the greening curtain wall A having the above configuration will be described.

  The greening curtain wall A of the present embodiment plants the plant 1 on the cultivating base 2 before installing it as the outer wall of the building. At this time, the plant 1 is planted on the surface 2 a of the cultivated soil base 2 from the gap between the horizontal members 7 adjacent to the top and bottom of the base holding member 3. And when planting the plant 1 in this way, since the cross member 7 of the base holding member 3 is connected to the vertical member 6 so as to be rotatable, the cross member 7 is connected to the axis on the one end 7c side. It rotates so that the surface becomes horizontal at the center of O1, and the clearance gap between the horizontal members 7 adjacent up and down is enlarged. Thereby, even when planting 1 from the surface 2a side to the cultivating soil base 2, the cultivating substrate is easily and suitably passed through the gap between the lateral members 7 which are adjacent to each other without the cross member 7 being in the way. Plant 1 is planted in 2. And after giving planting 1 in this way, the some cross member 7 is rotated, and it returns to the predetermined position which inclines upward gradually as it goes to the other side edge part 7d from the one side edge part 7c, respectively.

  Next, the greening curtain wall A to which the planting 1 has been applied is fixed to a marion, a fastener or the like together with the glass curtain wall 11, the metal curtain wall 12, the stone curtain wall 13, and the like and installed on the outer periphery of the building.

  Here, at the stage where the greening curtain wall A is installed as the outer wall of the building, the plant 1 does not grow greatly. In a conventional curtain wall configured to hold the culture base 2 with a mesh, the culture base 2 is exposed in this state, so that it does not look good. On the other hand, in the greening curtain wall A of the present embodiment, the cross member 7 of the base holding member 3 that holds the culture base 2 is inclined upward to cover the surface 2 a of the base 2. For this reason, when this greening curtain wall A is looked up from the bottom until the plant 1 grows greatly between the horizontal members 7 adjacent to the upper and lower sides, the cultivated soil base 2 cannot be seen, and the plurality of horizontal members 7 The lower surface can be seen in a continuous state in the vertical direction T1. Thereby, by forming the base holding member 3 with a metal such as aluminum, an appearance as if the metal curtain wall 12 is installed is formed, and until the plant 1 grows large (preferably wall greening) Until it is applied), the appearance is not impaired as in the case where a net is used as the substrate holding member.

  Further, water W is supplied from the irrigation tube 4 to the cultivating base 2 of the greening curtain wall A thus installed, for example, automatically or manually periodically. At this time, the water W supplied from the irrigation tube 4 flows down from the upper end 2b side to the lower end 2e side of the cultivating base 2, as shown in FIG. And the water W supplied to this cultivation base 2 flows down from the upper end part 2b side to the lower end part 2e side, and the upper end part 2b side of the cultivation base 2 will be in a dry state, and the lower end part 2e side will be in an overhumid state in many cases. However, in the greening curtain wall A of the present embodiment, since the water retaining part 5 is provided on the upper end 2b side of the cultivation base 2, the water W supplied from the irrigation tube 4 is temporarily retained in the water retaining part 5. Then, it is gradually supplied to the lower end 2e side. For this reason, the supplied water W does not rapidly flow down the cultivating base 2, and the upper end 2b side of the cultivating base 2 is not in a dry state and the lower end 2e side is not in an overhumid state.

  Moreover, the water storage part 10 is provided in the lower end part 3a side of the base | substrate holding member 3, and the water W which flowed down to the lower end part 2e side of the soil cultivation base | substrate 2 is temporarily stored by this water storage part 10. FIG. For this reason, it becomes possible to supply again the water W which flowed down the soil foundation 2 from the water storage part 10 to the soil foundation 2 and the drying of the soil foundation 2 is prevented reliably.

  Furthermore, in the greening curtain wall A of this embodiment, since the surface 2a of the cultivation base 2 is covered with the cross member 7 of the foundation holding member 3, the temperature rise of the cultivation base 2 due to direct sunlight or the like is prevented. In addition to this, since the highly reflective paint is applied to the surface of the cross member 7, the temperature rise of the soil base 2 is suppressed, and the drying of the soil base 2 is suppressed. For example, even when the temperature of the soil foundation 2 reaches 40 to 50 ° C. due to direct sunlight, it can be suppressed to about 35 ° C. by applying a highly reflective paint. As a result, the soil foundation 2 can be more reliably prevented from drying.

  In this way, the water content of the cultivating base 2 is the growth of the plant 1 by the water retaining part 5 provided on the cultivating base 2, the water storage part 10 provided on the base holding member 3, the cross member 7, and the highly reflective coating applied to the cross member 7 The plant 1 is reliably maintained in a state suitable for the plant 1 and the plant 1 is preferably grown even if the irrigation frequency is reduced.

  Further, in the greening curtain wall A of the present embodiment, since the cross member 7 is provided so as to be gradually inclined upward from the one side end portion 7c toward the other side end portion 7d, as shown in FIG. At times, the rainwater W ′ is actively taken into the cultivation base 2 by the cross member 7. As a result, the rainwater W 'can be effectively used to prevent the soil foundation 2 from drying more reliably, and the irrigation frequency can be further reduced.

  And by maintaining the water-containing state of the cultivation base 2 in a suitable state as described above, as shown in FIG. 2 to FIG. 4, the plant 1 grows greatly outside through the gaps between the adjacent horizontal members 7. Eventually, the green curtain wall A, which looked like a metal curtain wall, is transformed into a green panel by the plant 1. Thereby, suitable greening is given to the wall surface of a building.

  On the other hand, when the greening curtain wall A installed as the outer wall of the building is exposed to the wind and rain, the cultivating soil base 2 may deteriorate and the cultivating soil may fall off. However, in the greening curtain wall A of the present embodiment, the crosspiece 7 Is gradually inclined upward as it goes from the one side end portion 7c to the other side end portion 7d, the deteriorated soil is held by the cross member 7. For this reason, the soil does not fall outside from the mesh of the conventional net.

  Therefore, in the greening curtain wall A of the present embodiment, the base support member 3 composed of a pair of vertical members 6 and a plurality of cross members 7 arranged at predetermined intervals in the vertical direction T1 is provided as the soil cultivation base 2. Therefore, it is possible to form the curtain wall A by reliably holding the cultivating base 2 by the base holding member 3.

  And the cross member 7 of this base | substrate holding member 3 is formed in plate shape, protrudes outside from the surface 2a side of the soil cultivation base | substrate 2, and the other side edge part 7d is distribute | arranged upwards rather than the one side edge part 7c. (Because the cross member 7 is provided so as to be gradually inclined upward from the one side end 7c toward the other end 7d), it is installed as an outer wall of the building and is adjacent to the top and bottom. When the greening curtain wall A is looked up from the bottom until the plant 1 grows greatly from between the cross members 7, the cultivated soil base 2 is not visible, and the lower surfaces of the plurality of cross members 7 are continuous in the vertical direction T1. Visible in state. As a result, when the substrate holding member 3 is formed of a metal such as aluminum, for example, it is possible to form an appearance as if a metal curtain wall is installed, compared with the case where a net is used as the substrate holding member. And it becomes possible to improve the appearance until plant 1 grows large (until wall surface greening is performed suitably).

  Further, since the cross member 7 is provided as described above, even when the soil foundation 2 is deteriorated, the fallen soil is held by the cross member 7, and the soil is removed from the net of the net as in the past. It can be reliably prevented from falling outside.

  Furthermore, by providing the cross member 7 as described above, it becomes possible to positively take rainwater W 'into the cultivating base 2 side with the cross member 7 during rain. Moreover, since the surface 2a of the cultivation base 2 is covered with the plate-shaped cross member 7, drying of the cultivation base 2 can be suppressed. Thereby, it is possible to easily maintain the cultivated soil base 2 in a water-containing state suitable for the growth of the plant 1 by the cross member 7 and to reduce the irrigation frequency.

  Further, since the cross member 7 is provided so as to be rotatable around the axis O1 extending in the horizontal direction T2 with respect to the vertical member 6, the cross member 7 is rotated so that the cross members 7 adjacent to each other in the vertical direction are rotated. The gap can be increased. Thereby, even if it is a case where planting 1 is given to the cultivation base 2 from the surface 2a side, it is possible to apply the planting 1 to the cultivation base 2 easily and suitably without the cross member 7 being in the way. become. In addition, the green curtain wall A can be easily maintained.

  Furthermore, water W (rain water W ′) that has flowed down from the upper end 2b side to the lower end 2e side of the cultivating base 2 is provided by providing the water storage portion 10 having a concave cross section on the lower end 3a side of the base holding member 3. The water storage unit 10 can temporarily store the water. As a result, it is possible to prevent the soil foundation 2 from drying more reliably, and to reduce the irrigation frequency and allow the plant 1 to grow appropriately.

  Moreover, it can suppress that the upper end part 2b side of the cultivation base 2 will be in a dry state by providing the water retention part 5 in the upper end part 2b side, and forming the cultivation foundation 2 more reliably. It becomes possible to maintain the water-containing state in a state suitable for the growth of the plant 1.

  Further, since the base holding member 3 is formed by applying a highly reflective paint on at least the surface of the cross member 7, the soil base 2 held by the base holding member 3 can be prevented from becoming excessively hot. As a result, it is possible to prevent the soil base 2 from being dried and to reduce the irrigation frequency so that the plant 1 can be suitably grown.

  Therefore, according to the greening curtain wall A of the present embodiment, the pair of vertical members 6 and the other end portion 7d are arranged above the one end portion 7c on the surface 2a side of the soil foundation 2 so as to be disposed above. By providing the base holding member 3 composed of a plurality of plate-like cross members 7, it is possible to improve the appearance until the plant 1 grows, and the culture soil falls due to the deterioration of the culture base 2. This makes it possible to prevent the soil foundation 2 from drying and to effectively use the rainwater W ′ to reduce the frequency of irrigation.

  As mentioned above, although one Embodiment of the greening curtain wall concerning this invention was described, this invention is not limited to said one Embodiment, In the range which does not deviate from the meaning, it can change suitably. For example, in this embodiment, the cross member 7 of the base holding member 3 is provided so as to be rotatable with respect to the vertical member 6, and the cross member 7 is rotated to increase the gap between the cross members 7 adjacent to each other in the vertical direction. To make planting and maintenance easy. On the other hand, the base material holding member according to the present invention may be provided with the cross member 7 fixedly connected to the vertical member 6. Moreover, the cross member 7 may be detachably connected to the vertical member 6, and in this case as well, by removing the cross member 7, planting and maintenance on the cultivated soil base 2 can be performed as in the present embodiment. It can be carried out easily and suitably.

  Further, in the present embodiment, the cross member 7 of the base holding member 3 is formed in a flat plate shape, and is provided so as to be gradually inclined upward from the one side end portion 7c toward the other side end portion 7d. However, for example, as shown in FIG. 6, the base holding member 3 may be configured by including the cross member 7 formed in a substantially L shape, and in this case, the same effect as in the present embodiment can be obtained. it can. Therefore, in the base holding member according to the present invention, the cross member 7 is formed in a plate shape and is provided so as to protrude outward from the surface 2a side of the soil base 2, and one side of the surface 2a side of the soil base 2 As long as the other end portion 7d is disposed above the end portion 7c, the configuration of the present embodiment is not necessarily limited.

  On the other hand, as shown in FIG. 5, when curtain walls A, 11, 12, and 13 are installed as the outer walls of the building, in the vertical direction T1 between the adjacent curtain walls A, 11, 12, and 13 when it rains. Rainwater W ′ flows down the extending joint 15. In the present embodiment, the rainwater W ′ is effectively used only by the cross member 7. For example, as shown in FIG. 7, the curtain wall A, 11, 12, 13 adjacent to the base holding member 3 is used. A rainwater introduction section 16 for introducing rainwater W ′ flowing down the joint portion 15 extending in the vertical direction T1 into the cultivation base 2 may be provided to constitute the greening curtain wall A. In this case, for example, as shown in FIGS. 7 and 8, rainwater W ′ flowing down the joint portion 15 is supplied to the soil foundation 2 by the rainwater introduction portion 16, and the soil foundation 2 is moved from the upper end 2b side to the lower end. The rainwater W ′ flowing down to the 2e side is again discharged from the water reservoir 10 to the joint 15. For this reason, rainwater W 'flows down the joint portion 15 while being sequentially supplied / discharged from the soil cultivation base 2 of the greening curtain wall A installed above to the soil cultivation base 2 of the greening curtain wall A below. Thereby, it is possible to easily maintain the cultivated soil base 2 in a water-containing state suitable for the growth of the plant 1 by the rainwater introduction unit 16 in addition to the cross member 7, and to further effectively use the rainwater W ′ and to reduce the irrigation frequency. It becomes possible to reduce.
