Description

[Detailed explanation of the idea] <Industrial application field> The present invention relates to a planter.

<Conventional technology> Conventionally, this type of device had a peripheral wall made of FRP, the upper end of which was bent outward to provide a rim, into which soil was directly poured.

<Problems with conventional technology> Even though conventional products are made of FRP, they have low pressure resistance and are at risk of destruction because they receive earth pressure only on the surrounding walls, and the soil is in close contact with the walls and bottom, making it difficult for plants to grow. It had poor root circumference and was prone to root erosion and water withering, which was not favorable for growth, and furthermore, it had a poor appearance and a poor sense of nature.

<Means for solving the problem> The surface is made into a crater shape, a urethane coating film or an acrylic coating is formed on the surface, the upper edge of the peripheral wall is bent inward to provide a flange, and a reinforcing plate is installed on the inner surface. and a heat insulating board, and a net is laid on the bottom while maintaining an air layer.

<Function> By the above means, the surface becomes an uneven, tile-like glossy surface, the surrounding wall has increased strength due to multiple walls and insulation from external heat, and the soil does not come into close contact with the surrounding wall and the bottom surface.

<Example> An example of the implementation of the present invention will be described with reference to the drawings. The main body A is made of FRP with a form and structure well known in this technical field, and the surface of the peripheral wall 1 is sprayed with water-based epoxy resin. It is formed into a crater shape 2 and a urethane coating film or an acrylic coating film 3 is formed on its surface, the upper edge of the peripheral wall 1 is bent inward to provide a flange 4, and the bottom surface 5 is provided with a recess 6 as appropriate. At this position, a net receiving part 7 is provided in a protruding manner within the recessed part 6, and a foot part 8 is made to protrude outward.

Reinforcing plates 9 and heat insulating plates 10 are alternately arranged along the inner surface of the peripheral wall 1 at predetermined width intervals, and the circumferential wall 1 and the reinforcing plates 9 or the heat insulating plates 10 form a double wall.

The flange 4 is formed by bending the upper end of the peripheral wall 1 inward, and consists of a horizontal flange 4' and a lower heavy flange 4'' whose tip is further bent downward.

The reinforcing plate 9 is made of an FRP board, a composite laminate made by impregnating polyester resin into a polyester short fiber nonwoven fabric containing microballoons and integrating a glass resin layer, or other composite board, and is formed into a predetermined width. They are formed along the inner surface of the peripheral wall 1 at appropriate intervals.

The heat insulating board 10 is made of a plate-shaped part having a heat insulating effect, such as styrofoam or soft urethane foam.
The reinforcing plates 9 are formed to have a predetermined width and are formed along the inner surface of the peripheral wall 1, and are alternately provided with reinforcing plates 9.

A recess 6 for air storage and water storage is provided on the bottom 5, and a net 11 is laid on the bottom 5 to maintain an air layer between the bottom of the recess 6 and the net 11.
A net receiving portion 7 is provided in a protruding manner at a predetermined location of the recess 6, and the net 11 is supported by the net receiving portion 7 and the bottom surface 5. A recessed part that becomes the foot part 8 is provided on the outside of the recessed part 6, and the recessed part is filled with a filler 12 such as hydrous polyester resin or resin concrete so that it is substantially flush with the bottom surface of the recessed part 6. A drain plug 13 having a drainage hole is installed at an appropriate position on the bottom of the recess 6 so that a predetermined amount of water does not accumulate in the recess 6.

The net 11 is a net-like material through which the air in the recess 6 flows, and it catches the soil put into the main body A, prevents it from falling into the recess 6, and replenishes air to the soil through the air circulation. This net includes, for example, a reinforcing net 11' made of polyethylene with a thick and coarse mesh as the lower part, and a support net 11'' with a thin and dense mesh as the lower part.
The support net 1 is formed by a double net with
Soil is placed on top of the net 11. A water absorbing tube 14 is suspended from the net 11, and a water absorbing filler 15 is filled inside the net 11, and water in the recess 6 is absorbed by the filler 15.
It is absorbed into the soil through .

Furthermore, 17 in the figure is a polystyrene for a net receiver placed in the recessed part 6.

<Effects> This invention makes the surface of the FRP body into a crater shape with water-based epoxy resin, forms a urethane coating or acrylic coating on the surface, and bends the upper edge of the peripheral wall inward to provide a rim. A reinforcing plate and a heat insulating plate are placed along the inner surface of the peripheral wall, and a net is laid on the bottom to maintain an air layer, so even if the main body is filled with soil, the peripheral wall will be reinforced by the reinforcing plate. It will not be deformed or destroyed by earth pressure. Furthermore, the presence of the heat insulating board allows the inside to be kept warm by insulating it from the outside, and the soil does not come in close contact with the surrounding wall, resulting in a good root circumference. Moreover, since the net is laid on the bottom surface, excess water during irrigation does not accumulate on the bottom surface, preventing it from falling down and uprooting, and air circulation is also improved, so plants grow very well.

In addition, even if it is made of FRP, the surface is crater-shaped and has a urethane coating or acrylic coating on the surface, so it looks thick in appearance and gives the appearance of a natural object. It can also provide gloss and coloring that can be maintained for a long period of time.
