However, the greening structure in which the planting units proposed in Patent Documents 1 to 3 are installed on a wall surface or an inclined roof needs to produce a large number of these planting units in advance, which takes time and costs. There was a problem that became high. Moreover, since the soil is spread over the whole inside of the frame, a single unit weight becomes large. For this reason, since a frame member supports a planting unit with a wall surface or an inclined roof, it is necessary to make a material and a fixed state strong, and material cost is large. Furthermore, since it is necessary to have a structure in which the frame member is incorporated in the installation surface in advance, the construction is troublesome and the cost is high.
Moreover, since the planting base formed by the spraying of patent document 4 sprays soil with fixed thickness over the whole installation surface, there existed a fault that a load became large. For this reason, there is a problem that installation is difficult on an inclined roof or the like where the load is restricted.

  The present invention has been made in view of the above-described problems, and has an object of providing a greening structure of a building with improved workability and reduced cost by having a light weight and simple structure. To do.

In order to achieve the above object, in the greening structure of a building according to the present invention, a net member laid so as to cover an installation surface such as a wall surface of a building or an inclined roof, and a support member fixed at an arbitrary position of the net member; It is characterized by comprising a cultivated soil base supported by a support member and made of a lightweight material, and a plant planted on the cultivated soil base.
In the present invention, by using a lightweight material for the cultivation base, it is possible to simplify the attaching work of the net member, the support member, and the cultivation base, so that the construction time can be shortened and the workability is improved. be able to.

In the building greening structure according to the present invention, the support member is preferably a housing member having an opening.
In the present invention, it is possible to install the culture foundation by a simple operation of simply placing the culture foundation in the housing member.

Moreover, in the greening structure of the building which concerns on this invention, it is preferable that a supporting member is a frame member which supports a cultivation base.
In the present invention, for example, the frame member can be easily fixed to the net member by a frame member having a frame shape.

Moreover, in the greening structure of the building which concerns on this invention, it is preferable that the cultivation base is formed with the material which has a foam as a main component.
In the present invention, for example, a soil foundation can be formed by blending a fiber material having heat-fusibility into an inorganic foam as a main component and solidifying it by heat treatment. Since the fibers are bonded to each other and the fibers and the inorganic foam are bonded to each other to obtain a three-dimensional net-like reinforcing structure, the weight can be reduced and the shape can be maintained. Therefore, the support member and the net member that support the cultivation base made of such a material can have a simple structure.

  According to the greening structure of the building of the present invention, the structure can be simplified by reducing the weight of the support members and net members that support the soil base by using the soil base made of a lightweight material. Cost can be reduced. Moreover, since the attachment operation | work of a net | network member, a supporting member, and a cultivation base can be simplified, construction time can be shortened and workability | operativity can be improved.

Hereinafter, the greening structure of the building by 1st embodiment of this invention is demonstrated based on FIG. 1 and 2. FIG.

As shown in FIG. 1, the greening structure 1 includes a net member 3 that is formed so as to cover a wall surface 2 with a mesh formed therein, and a storage member 4 (support member) fixed at an arbitrary position of the net member 3; It is comprised roughly from the cultivation base 5 which is supported by the accommodation member 4 and which has a lightweight foam as a main component, and the plant 6 planted in the cultivation base 5.
In the present embodiment, a plurality of soil foundations 5 are arranged on the wall surface 2.

The net member 3 shown in FIG. 1 is a net in which linear members made of, for example, lightweight polyethylene or nylon are knitted in a lattice shape. And the method of laying the net | network member 3 in the wall surface 2 is preferable, for example, the method of suspending from the upper direction, and the method of directly fixing to the wall surface 2 with an anchor etc. In addition, the magnitude | size of the net | network member 3 shown in FIG. 1 is arbitrary, and may be divided | segmented into plurality.
As shown in FIG. 2, the housing member 4 is made of a net made of the same material as that of the net member 3, and has an opening 4a on the upper surface. Then, for example, a fastening member such as a string member or a fixing member (not shown) such as a clip is fixed to the net member 3 with the opening 4a facing upward, and the cultivating base 5 is accommodated in the accommodating member 4. Become.

As shown in FIG. 1, the soil foundation 5 is solidified by heat treatment, for example, by mixing heat-fusible fibers with a base material described in JP-A-2002-119130, that is, an inorganic foam such as pearlite. The base material formed is used.
The solidified foundation 5 thus solidified has a special frame because a three-dimensional net-like reinforcing structure is obtained by bonding between fibers having heat-fusibility and bonding of fibers and inorganic foam. There is no need to cover the periphery with a material or bag, and the shape can be maintained. For this reason, it does not scatter due to the influence of wind or the like. Furthermore, since the weight per unit volume of the inorganic foam which is the main component of the soil foundation 5 is, for example, 0.5 kg / liter or less, it is lightweight and has appropriate water retention performance and drainage performance.
Note that the soil foundation 5 used in the present embodiment is previously solidified to a size that can be accommodated in the housing member 4. Further, it may be divided into a plurality of parts so as to be easily carried.

As shown in FIGS. 1 and 2, the plant 6 planted on the cultivation base 5 is preferably a ground cover plant (undergrowth) such as moss or sedum, a vine plant, or the like. In particular, when the plant 6 is a vine, it can be grown and greened so as to cover the entire surface of the net member 3 along the mesh of the net member 3.
Further, as shown in FIG. 1, an irrigation pipe 7 is guided along the net member 3 in order to supply water to the cultivating base 5.

As shown in FIGS. 1 and 2, the greening structure 1 is installed by placing the mesh member 3 on the wall surface 2, attaching the accommodating member 4, and then accommodating the cultivated soil base 5 in the accommodating member 4.
In addition, the accommodation member 4 is fixed to the mesh member 3 in an arbitrary position, for example, in the vertical and horizontal directions of the mesh at predetermined intervals, and a cultivation base 5 is provided in each accommodation member 4. 2 may be fixed.

In the greening structure of the building according to the first embodiment described above, the structure is obtained by reducing the weight of the support member 4 and the net member 3 that support the soil base 5 by using the soil base 5 made of a lightweight material. Can be simplified, and material costs can be reduced. In addition, since the attachment work of the net member 3, the storage member 4 and the soil base 5 can be simplified, the construction time can be shortened and the workability can be improved.
Moreover, the use of the solidified soil eliminates the need for a bag or a pallet frame for storing the soil, thereby simplifying and reducing the configuration of the greening structure 1 and facilitating the construction.
Further, by reducing the weight of the greening structure 1, the applicable range of installation can be widened even in a building with a load limit.
Further, in the present greening structure 1, by installing the installation surface such as the wall surface 2 of the building so as to be covered with the plant 6 and making it green, a temperature reduction effect can be achieved and it can contribute to the suppression of the urban heat island phenomenon.
