Description

[0001]
[Industrial applications]
The present invention relates to a device that can easily plant plants, flowers and other plants, particularly a planting device provided for growing plants on the roof or roof of a building, and a planting device of this type. On the drain pan.
[0002]
[Prior art]
2. Description of the Related Art In recent years, attempts have been actively made to plant inorganic plants in urban areas by planting plants on a large scale on the rooftop and other spaces of buildings.
In such a case, in many cases, a concrete layer of the presser is formed on the waterproof layer on the slab surface of the building or the like, and a gravel layer made of sand, gravel, etc. Plants are planted by stacking layers sequentially.
[0003]
However, in order to obtain sufficient water retention and drainage for plants, it is necessary to introduce a considerable amount of sediment into the waterproof layer, and since the concrete layer has a considerable weight, these weights have an adverse effect on buildings. Problem.
Therefore, the present applicant has previously disclosed a lightweight planting apparatus having excellent water retention and drainage properties (see, for example, Japanese Patent No. 2531542).
[0004]
This planting apparatus fixes a waterproof layer on a slab surface formed on the roof of a building or the like, and on the upper surface of the waterproof layer, a water retention material having a nonwoven fabric or the like, and a drain having a concave portion and a convex portion 2. A water retention / water supply / drainage means composed of a board or the like is provided, and a planting layer composed of a gravel layer and a soil layer is further laminated above the water retention / water supply / drainage means. Drainage can be obtained.
For this reason, the concrete layer provided in consideration of drainage becomes unnecessary, and the planting layer is also set to a necessary minimum thickness in consideration of the length of root hairs of plants and the like, for example, about 50 mm by improving water retention. It is possible.
[0005]
[Problems to be solved by the invention]
Therefore, the above-mentioned conventional planting apparatus has an excellent function of reducing the weight of the entire apparatus and avoiding adverse effects on buildings, but still has some problems to be improved. .
That is, no measures against the wind are taken. This type of equipment is often installed in high places such as the rooftops of buildings, but in such high places there is always an irregular wind, which causes the soil in the guest soil layer to scatter. Cheap.
In addition, it is desirable to construct the guest soil layer as thin as possible from the viewpoint of load on a building or the like. However, if it is made too thin, the roots of the planted plant will not be stretched and will collapse even in a slight wind. This is particularly remarkable when plants are planted, and in the case of plants that grow to a certain height, it is difficult to erect them even when there is no wind.
[0006]
Furthermore, once the soil layer is constructed, it is difficult to cultivate the soil of the soil layer with this type of equipment, which results in poor ventilation below the soil layer, which has a serious effect on plant growth. Will be.
Furthermore, at present, there is also a request from users who wants to plant trees not only on a horizontal surface such as a rooftop but also on an inclined surface such as a sloped roof, etc. When applied, the installation state becomes unstable, and it is particularly difficult to maintain the soil of the guest soil layer.
A technique for solving such a point is disclosed in Japanese Patent No. 2717632. However, in this technique, there are problems that the fixing of the device is complicated, the construction cost increases, and the construction takes time.
The present inventors have further worked on research and development of a new planting device, and the planting device has been registered as Patent No. 3,280,912, Patent No. 3,286,753, and Patent No. 3,328,583.
However, in these planting apparatuses, the drain plate (water retention / drainage means) and the truncated cone-shaped hollow body as the fixing means are integrally formed, and the overall shape is complicated and large. Therefore, when the drain plate is formed of a resin material, it is not easy to manufacture a mold and the cost increases. In addition, storage and transport of the product also require time and effort.
For this reason, the drain plate and the hollow body are composed of different members, and first, the hollow body is installed and fixed, and then, an attempt is made to install the drain plate through the hollow body at the opening of the drain plate. However, there is an inconvenience that work efficiency is not improved.
[0007]
[Means for Solving the Problems]
The present invention relates to a plant planting device installed on the rooftop, roof or the like of a building, a waterproof layer provided at the bottom of the device, and the waterproof layer for preventing plant roots or the like from leaking out of the device.

In addition, the shape of the bracket part 5 is formed in a square with one side of about 129 mm. On the other hand, the opening 5 has a square shape with one side slightly larger than the bracket portion 5, and an upright wall 7 having an inclined surface is formed above the periphery of each side of the square. Therefore, by inserting the hollow body 4 from above the opening 5, the edge of the bracket 6 of the hollow body 4 slides down the inclined surface of the upright wall 7, and the bracket 6 is easily cut in the opening 5. The work efficiency is remarkably improved because it is fitted in the opening 5.
[0015]
In FIGS. 2 and 3, ventilation holes for circulating air to the soil layer are provided by small through holes provided in rectangular projections formed at intersections of the straight pipes 2a and through holes formed at the top of the hollow body 4. A mechanism is configured to allow air to circulate through the hollow body, the drain, and the soil layer.
[0016]
FIG. 4 is a perspective view showing a base of the drain pan C. A base 8 is constituted by a plurality of straight pipes 2 a crossing each other to form a water retaining section 1 and a drain section (path), and the opening 5. I have. FIG. 5 is a perspective view of the drain pan C including the base 8 of the drain pan C and the hollow body 4 fitted into the opening 5 of the base 8.
[0017]
Next, construction of a planting device on a rooftop surface using the drain pan according to the above configuration will be described.
First, in FIG. 1, a root guard B corresponding to the shape area of the planting device to be constructed is installed on the surface of the waterproof layer A.
Next, a double-sided adhesive tape T is applied to the entire surface of the root guard B, the peeling seal on the surface is removed, and the base 8 of the drain pan C shown in FIG. At this time, the adhesive surface of the double-sided adhesive tape T is exposed at the opening 5 in the base 8 of the drain pan C. In this state, each side of the bracket 6 of the hollow body 4 is replaced with each side of the opening 5. The hollow body 4 is pushed into the opening 5 approximately correspondingly.
Then, as shown in FIG. 3, the edge of the bracket 6 slides down the slope of the upright wall 7 formed on the periphery of the opening 5, so that the bracket 6 is easily and accurately inserted into the opening 5 as shown in FIG. 5. Is fixed to the adhesive surface of the adhesive tape T in a state of conforming to.
[0018]
Next, the soil is incorporated on the set drain pan C in accordance with the height of the hollow body 4 to form the customer soil layer D. Next, after the seeds of a desired plant are scattered or plant seedlings or plants are fixed on the guest soil layer D, the wind control net E is installed on the surface of the guest soil layer D. Then, the wind prevention net E is locked to the hollow body 1 by screwing.
[0019]
【The invention's effect】
As described above, the invention of the present application is configured such that the hollow body and the drain pan base are formed by different members, and the assembling of the hollow body to the drain pan base during the construction of the planting apparatus in the configuration related to the two is very important. Since it can be easily and quickly performed, effects such as improvement of work efficiency of planting equipment construction, easy handling of drain pans, reduction of manufacturing cost, and the like can be obtained, which greatly contributes to realization of greening of urban space.
