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

C1 is a resin mat laminated on the upper surface of the roof guard B, C2 is a fiber mat polymerized on this resin mat C1, and this fiber mat C2 is impregnated with excess water as described later to absorb water. It is designed to store and hold. C3 is a drain plate made of resin, and a large number of truncated cone-shaped convex portions C31 and substantially conical concave portions C32 are alternately and continuously formed over the front surface, and the planar top portion 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 F and the drain plate C3, which will be described later, so as to prevent soil and the like of the planting layer F from flowing out toward the drain plate. The water retention and drainage means C is defined by C1 to C4 above.
Is configured. D1 is a gravel layer provided on the filter layer C4, D2 is a soil layer D2 laminated on the gravel layer D1, and various plants are planted by the gravel layer D1 and the soil layer D2. A planting layer D is formed.

E is a net material E interposed between the gravel layer D1 and the soil layer D2. The net material E has a size that allows the root hairs of the plants planted in the planting layer D to pass through sufficiently. It has a mesh. F is a wire made of stainless steel as a long body that connects the net material E and the waterproof layer A vertically at a plurality of points. The wire F has its upper end locked to the waterproof layer A, and
The upper end portion penetrates the root guard B and the water retention / drainage means C and is locked to the net material E. In this embodiment, a wire made of stainless steel is used as the elongated body, and an intermediate portion bent on the hairpin is inserted into and locked by the waterproofing means A, and both ends of the water retaining / water draining means C are penetrated. It is locked to the net material E. The wire F is inserted into the water permeable hole C31a formed in the drain plate C3.

Next, the operation of this embodiment will be described based on the above configuration. Due to precipitation or removal of water from the planting layer F, part of the water is impregnated and held in the planting layer F, and the other passes through the filter layer C4 and falls to the drain plate C3 and is stored in the recess C32 ( (See FIG. 3).

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

When the amount of water L retained in the planting layer F is reduced and the plant is dried, the water retained on the fiber mat C2 of the water retaining layer is used as water vapor Lg to form the drain plate C3.
The water reaches the planting layer D through the water permeable holes C31a of the convex portion C31 to appropriately supply water (see FIG. 4). In addition,
Since the inner portions of each convex portion C31 communicate with each other,
At any time, it serves as an air passage and fresh air is supplied to the roots of the plants (see the arrow in FIG. 5), and various pests can be prevented.

As described above, in this embodiment, since proper water retention and drainage can be obtained, the thickness of the planting layer should be kept to the minimum necessary thickness in consideration of the length of the hair root of the plant. Although it is possible to significantly reduce the load on the building, the installation state is extremely stable while being lighter.

That is, since the gravel layer D1 which is apt to be displaced in the waterproof layer A is pressed by the mesh material E connected to the waterproof layer A, the sloping wall surface S of the apparatus is provided as shown in FIG. The planting layer D will not be displaced or blown off from the initial installation position even when it is attached to a wall or the like, or when it is exposed to strong wind, and is firmly installed on the wall surface. Further, the soil layer D2 is not pressed by the net material E1, but the soil layer D2 is viscous and thus is less likely to be displaced, and the roots of the planted plant have the net material E.
Since the soil and the gravel layer D1 are entangled and integrated with each other, the soil layer D2 is also held in place together with the other layers.

Incidentally, in FIG. 6, the waterproof layer is adhered to the concrete slab surface S inclined with respect to the horizontal plane h, and is fixed at a plurality of places by bolts BL. Also,
FT is a flushing tape adhered to a fixed position 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 the side end of the apparatus in this embodiment. It has become.

By the way, in the above embodiment, the waterproof layer A, the root guard B, the resin mat C1, the fiber mat C
2, the wire F is inserted in advance through the drain plate C3, the filter layer C4, the net material E, etc. to form the unit section Y, which facilitates the work in the installation work.

That is, in the case where the unit portion Y is constructed as described above, after fixing the waterproof layer A, the gravel p is held on the filter layer C4 while being held upward as shown by the alternate long and short dash line in FIG. Gravel layer D1 until it is sent and has an appropriate thickness
After that, the earth and sand e may be fed onto the net material E to form the customer soil layer D2. In this way, the gravel layer D1 is formed.
By forming the wire, the wire F is not completely buried in the gravel layer D1, and the meshing work with the mesh material E can be performed efficiently, so that the work can be advanced efficiently. .

In the above embodiment, the net material E is provided between the gravel layer D1 and the soil layer D2, but the net material E may be on the gravel layer D1. Soil layer D2
It is also possible to lay it in the inside, and depending on the size of the mesh, it can also be laid on the upper surface of the soil layer D2. In addition to this, a plurality of net materials may be provided at different positions in the planting layer D at different positions in the vertical direction, and these may be connected by a connecting member such as the wire F.

On the other hand, as the connecting member for connecting the net material and the waterproof layer, it is possible to apply other than the wire F as described above. For example, the waterproof layer and the net material may be connected by a resin wire material, a belt-shaped member, or the like, and it is also possible to use a rod-shaped member. However, when using a rod-shaped member, it is desirable to use one having flexibility so that it does not hinder walking.

Further, as the connecting member, it is also possible to use the members shown in FIGS. 7 and 8. The connecting member G shown here is composed of a locking plate G shown in FIG. 7 and a wire F connecting the locking plate G and the net material E, and the locking plate G is fixed to the upper surface of the waterproof layer A. The bottom portion G1 has a rising portion G2 that rises vertically. In addition, here, a bent portion G that bends horizontally at the upper end of the rising portion G2.
2a is formed, and an insertion hole G2a1 for inserting the wire F is formed in the bent portion G2.

When this connecting member G is used, first, the rising portion G2 has the drain plates C3, C3 ...
The bottom surface G1 is fixed to the waterproof layer A, and the wire F is inserted into the insertion hole G2a of the bent portion G2.
It suffices to insert the wire F into the mesh material E and to lock the upper end portion of the wire F to the mesh material E, whereby the mesh material E is connected to the waterproof layer A. Thus, when the connecting member G is used, the wire F is attached to the rising portion G2 located above the drain plate C3.
Since it is sufficient to insert and lock the waterproof layer A at the bottom
In addition, the installation work becomes easier as compared with the case where the wire is directly inserted and locked, and since it is not necessary to make a hole in the waterproof layer A, there is no fear of impairing the waterproof property.

Further, in the above-mentioned embodiment, the water supply / drainage means is composed of the members C1 to C4, but the resin mat C1 and the filter layer C4 can be eliminated, and only the fiber mat C2 or the drain can be used. It is also possible to provide only the mat C3, 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, the net material is laid on at least the gravel layer of the soil layer and the gravel layer forming the planting layer, and the net materials are connected. Since it is connected to the waterproof layer fixed on the structure such as the roof or roof by the member, there is no fear that the planting layer will be blown off even in places or areas where strong winds blow, and the sloped surface of the roof etc. When it is installed in the plant, the planting layer will not be displaced or fallen off, and a solid installation state can be obtained. Furthermore, if the unit part is configured by inserting the connecting member fixed to the waterproof layer into the water retaining layer and the net material, the connecting member will be inside the planting layer when the planting layer is formed during installation work. The installation work can be performed efficiently without being buried in, and the construction cost can be reduced.
