DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS. In the figure, A is a waterproof layer adhered to the surface of the concrete slab S on the roof of the building,
On the upper surface of the waterproof layer A, a root guard B made of resin is provided to prevent the roots of plants from entering the waterproof layer.

C1 is a resin mat laminated on the upper surface of the root guard B, C2 is a fiber mat polymerized on the resin mat C1, and the fiber mat C2 is impregnated with excess moisture to remove moisture as described later. It is designed to store and hold. C3 is a drain plate made of resin, in which a large number of convex portions C31 having a truncated cone shape and concave portions C32 having a substantially conical shape are formed alternately and continuously over the entire surface, and a top surface of the convex portion C31 has a water-permeable hole C31a. .

C4 is a filter layer such as a non-woven fabric interposed between the planting layer D and the drain plate C3, which will be described later, so as to prevent earth and sand of the planting layer D from flowing out in the drain plate direction. And the water holding / draining means C by C1 to C4.
Is configured. D1 is a gravel layer provided on the filter layer C4, D2 is a soil layer laminated above the gravel layer D1, and various plants are planted by the gravel layer D1 and the soil layer D2. The planting layer D is configured.

E is a net material interposed between the gravel layer D1 and the soil layer D2. The net material E has a mesh size enough for the root hairs of the plants planted on the planting layer D to pass through. have.
F is a stainless steel wire as a connecting member for connecting the net material E and the waterproof layer A up and down at a plurality of locations. The lower end of the wire F is locked by the waterproof layer A, and the upper end of the wire F is locked by the net material E through the root guard B and the water retention / drainage means C. In this embodiment, a stainless steel wire is used as the connecting member, and the intermediate portion bent on the hairpin is inserted and locked in the waterproofing means A, and both ends of the water retaining / supplying / draining means C are penetrated. It is locked to the net material E. Note that the wire F is inserted into a water permeable hole C31a formed in the drain plate C3.

Next, the operation of this embodiment will be described based on the above configuration. A part of the water is impregnated and held in the planting layer D by the precipitation or drainage of the planting layer D, and the other water falls through the filter layer C4 to the drain plate C3 and is stored in the concave portion C32 ( (See FIG. 3).

If the amount of water L reaching the drain plate C3 is large and cannot be accommodated in the concave portion C32, the water L is transferred to the convex portion C3.
1 through the water-permeable hole C31a provided at the top of the fiber mat C
2 is absorbed and retained. When the amount of supplied water exceeds the above-mentioned suction amount, the water L is appropriately drained through a passage formed by the concave portion C32.

When the amount of the water L held in the planting layer D is reduced and the water is dried, the water held in the fiber mat C2 of the water holding layer is converted into the water vapor Lg to form the drain plate C3.
The water reaches the planting layer D through the water permeation hole C31a of the convex portion C31 and is appropriately supplied with water (see FIG. 4). In addition,
Since the inner portion of each convex portion C31 communicates with each other,
Normally, fresh air is supplied to the roots of the plants as an air passage (see arrows in FIG. 5), and various pests can be prevented.

As described above, in this embodiment, since appropriate water retention and drainage properties are obtained, the thickness of the planting layer is reduced to the minimum necessary thickness in consideration of the length of the root of the plant. Although the load on the building can be greatly reduced, the installation state is extremely stable while being lighter.

That is, since the gravel layer D1 which is likely to be displaced in the waterproof layer A is pressed by the net material E connected to the waterproof layer A, as shown in FIG. The planting layer D is not firmly displaced from the initial installation position and is not blown off even when it is attached to the wall or when it is made to be a strong wind, and is firmly installed on the wall surface. The soil layer D2 is not held down by the net material E. However, the soil layer D2 is viscous and hardly shifts, and the roots of the planted plant are entangled with the net material E and the gravel layer D1. , The soil layer D2 is also held in place along with the other layers.

In FIG. 6, the waterproof layer is bonded to the concrete slab surface S inclined with respect to the horizontal plane h, and is fixed at a plurality of locations by bolts BL. Also,
FT is a flushing tape attached to a position fixed by the bolt BL, W1 is a holding member protruding from the peripheral edge of the concrete slab surface S, and this holding member W covers a side end of the apparatus in this embodiment. It has become.

In the above embodiment, the waterproof layer A, the root guard B, the resin mat C1, the fiber mat C
2, a wire F is inserted in advance through the drain plate C3, the filter layer C4, the net material E and the like to constitute the unit portion Y, thereby improving the efficiency of the work in the installation work.

That is, when the unit portion Y is configured as described above, after the waterproof layer A is fixed, the gravel pe is put on the filter layer C4 while being held upward as shown by the dashed line in FIG. Gravel layer D until it reaches appropriate thickness
1 and then water retaining and drainage means by means of a connecting member,
The gravel layer and the net material are connected, and then the earth and sand e may be fed onto the net material E to form the guest soil layer D2. By forming the gravel layer D1 in this manner, the wire F becomes the gravel layer. D
Since it is no longer completely buried in 1 and the work of engaging with the net material E can be performed efficiently, the work can be performed efficiently.

In the above embodiment, the case where the net material E is interposed between the gravel layer D1 and the soil layer D2 has been described, but the net material E may be on the gravel layer D1. Customer soil layer D2
And, depending on the size of the mesh, can be laid on the upper surface of the soil layer D2. In addition, it is also possible to interpose net materials of a plurality of schools in vertically different positions in the planting layer D, and connect them with a connecting member such as a wire F.

On the other hand, a member other than the wire F as described above can be applied as a connecting member for connecting the net material and the waterproof layer. For example, the waterproof layer and the net material may be connected by a resin wire or a band-shaped member, or a rod-shaped member may be used. However, when a rod-shaped member is used, it is desirable to use a member having flexibility so as not to hinder walking.

Further, as the connecting member, those shown in FIGS. 7 and 8 can be used. The connecting member shown here is composed of a locking plate G shown in FIG. 8 and a wire F as an elongated body connecting the locking plate G and the net material E. A rising portion G2 which rises vertically to a bottom portion G1 fixed to the upper surface is formed.
Here, a bent portion G2a that is bent horizontally is formed at the upper end of the rising portion G2, and the bent portion G2a is further formed.
Is formed with an insertion hole G2a1 through which the wire F is inserted.

When this connecting member is used, first, the rising portion G2 is connected to the drain plates C3, C3,.
After fixing the bottom surface G1 to the waterproof layer A, the wire F is inserted into the insertion hole G2a1 of the bent portion G2a, and the upper end of the wire F is locked to the net material E. As a result, the net material E is connected to the waterproof layer A. As described above, when this connecting member is used, the wire F may be inserted and locked to the rising portion G2 located above the drain plate C3. The installation work is easier than in the case where the wire is directly inserted and locked, and since there is no need to make a hole in the waterproof layer A, there is no possibility that the waterproofness is impaired.

In the above embodiment, the water holding / water supply / drainage means is constituted by the members C1 to C4. However, the resin mat C1 and the filter layer C4 can be omitted. Board C
It is also possible to provide only three, and the water retention / drainage means applied to the present invention is not particularly limited to the one shown in the above embodiment. Also, the root guard B and the like can be deleted as necessary.

[0027]

As described above, in the planting apparatus according to the present invention, a net is laid on at least a gravel layer in a soil layer and a gravel layer constituting a planting layer, and the nets are connected. Because it is connected to the waterproof layer fixed on the building such as the roof or roof by the member, there is no risk that the planting layer will be blown off even in places where strong winds blow, areas, etc. In the case where the planting layer is installed, the planting layer is not displaced or dropped, and a firm installation state can be obtained. Furthermore, if the unit member is configured by inserting the connecting member fixed to the waterproof layer through the water holding / supplying / draining means and the net material, the connecting member is used to form the planting layer during installation work or the like. Installation work can be performed efficiently without being buried inside, and the construction cost can be reduced.
