Description

The present invention relates to a plant cultivation container for cultivating a plant such as a lawn on a rooftop of a building or on a veranda.

Conventionally, in urban areas, the use of building rooftops and verandas has been studied as a countermeasure against greening. For example, a waterproof sheet or a root-proof sheet is laid on the rooftop or veranda of a building, and mortar processing or synthesis is performed. After spreading a resin board, the soil was laminated | stacked on it and the plant was grown.

However, in the above method, when plant roots grow, they pass through the waterproof sheet or root-proof sheet, reach the rooftop or veranda, and enter the rooftop or veranda concrete to cause water leakage to the building. . Further, the above method has a drawback that it takes time and cost for construction and repair.

Recently, in order to eliminate the above-mentioned drawbacks, a plant cultivation apparatus in which containers for plant cultivation are spread has been proposed. For example, a plurality of interconnected thin boxes that are applied when forming a soil floor for plant cultivation over a certain range on a building roof such as a rooftop of a building or a veranda, and support the soil floor from below. Each of the container units is inclined downward at a gentle angle downward from the lower end of the peripheral frame, A bottom wall having a drainage hole at the lower end position thereof and closing the entire lower range of the peripheral frame, and horizontally disposed in the peripheral frame via a plurality of ribs on an upper surface of the bottom wall, A floor support plate through which water can flow from below, a lid for root prevention provided in the drain hole of the bottom wall, and a plurality of lower surfaces of the bottom wall depending on the bottom, such as on the building floor A plant cultivation apparatus characterized by comprising a support leg fixedly mounted on Are plan (e.g., see Patent Document 1.).
JP 2002-253052 A

However, since the plant cultivation apparatus fills a thin box-shaped container unit with soil, there is a drawback that when the water is poured after filling the soil, the soil flows and drains from the drain hole.

Further, the soil layer in the thin box-like container unit is thin and does not become hard, so it is not suitable for walking on it. For example, when a plant cultivation apparatus is installed on the roof of a hospital and planted on a lawn and used for walking by a patient or walking by a wheelchair, there is a drawback in that a dent is generated and it is difficult to walk or run the wheelchair.

In view of the above-mentioned drawbacks, the object of the present invention is to install on the rooftop or veranda of buildings and grow plants, so that water does not flow out even if watered, and people can walk on it. An object of the present invention is to provide a plant cultivation container that does not generate dents even when traveling in a wheelchair and has good walking ability and wheelchair traveling properties.

The container for plant cultivation according to the present invention has a container-shaped storage portion in which a side wall is erected around a substantially rectangular bottom wall, and an upper portion is open, and a leg portion is formed on the bottom surface of the bottom wall. A filter support member having water permeability, a soil outflow prevention filter, and an insole member are stacked and stored in the storage portion of the container body.

The container main body has a container-shaped storage portion having a side wall standing around a substantially rectangular bottom wall and open upward, and a leg portion is formed on the bottom surface of the bottom wall.

The planar shape of the bottom wall is approximately rectangular, and approximately square is preferable because the workability is good. or,
The bottom wall may be flat or inclined, but it is preferable that the bottom wall is inclined so that the water sprayed on the container for plant cultivation can be appropriately discharged. It is preferable to drill at the lowest position.

In particular, it is preferable that the bottom wall gradually becomes lower from the periphery of the bottom wall toward the center so that the center of the bottom wall becomes the lowest part, and a drain outlet is formed in the center. In this case, in order to hold the insole member, the rib may be erected so that the upper surface has the same height.

Examples of the rib include a rib erected radially from the center to the periphery, a plurality of cylindrical ribs erected concentrically around the center, and a concentric erection around the center. And a plurality of rectangular tube-shaped ribs. In addition, it is preferable that the cylindrical rib and the rectangular tube-shaped rib are provided with a through hole or a notch for drainage.

A side wall is erected around the bottom wall, and a container-shaped storage part is formed in which the upper side is open. However, the side wall may be erected vertically around the bottom wall. It may be erected and curved around. In addition, one or a plurality of step portions may be formed so that the opening area of the side wall increases toward the top. Furthermore, ribs for reinforcement may be formed on the inner and outer surfaces of the side walls.

The legs formed on the bottom surface of the bottom wall form a space between the plant cultivation container and the plant cultivation container construction site (for example, the rooftop of a building), enabling air circulation and drainage. The tube can be installed, and the shape thereof can be any conventionally known shape, for example,
Columnar bodies such as a columnar shape and a prismatic shape, and cylindrical bodies such as a cylindrical shape and a rectangular tube shape are exemplified.

Moreover, it is preferable that 1-5 convex parts are formed between the adjacent protruding item | line and protruding item | line.

It is preferable that a flat portion is formed on the heads of the protrusions and the protrusions, and that the heights thereof are approximately the same, since walking and running properties are excellent. In addition, it is preferable that a plurality of through holes are formed in the valleys between the ridges adjacent to the ridges, because drainage becomes smooth. Furthermore, when the flat part is formed in the head of the convex line and the convex part, a plurality of through holes for draining water may be formed in the flat part.

If the insole unit is bent by pressure from above, the walking performance and running performance deteriorate.Therefore, the insole unit has a flat portion around the ridge so that it is difficult to bend, and the peripheral wall portion stands at the end of the flat portion. It is preferable to be provided.

In addition, any method may be adopted as a method of connecting the side surfaces of the insole unit body, but protrusions and fitting portions are alternately formed in a flat portion around the insole unit body in a plan view. It is preferable that the projecting portion and the fitting portion of adjacent insole unit bodies are fitted and connected to each other so that the walking ability and the running property are excellent.

The insole member has a plurality of insole unit bodies whose side surfaces are connected to each other, but if the protrusions formed on adjacent insole unit bodies are connected so as to be orthogonal to each other, Rather than being connected so that the strips are parallel to each other, it is preferable because the walking performance and running performance are superior.

In particular, when two adjacent sides of a square insole unit are alternately formed with protrusions and fittings that can be fitted to each other, four insole units are adjacent to each other. It is preferable because the insole member can be formed by connecting the ridges formed on each other so as to be orthogonal to each other. In addition, it is preferable that the four insole units have the same shape because they can be stacked and stored and transported in a compact manner.

The insole member and the insole unit are preferably stored so as to cover the entire storage portion of the container body, and the insole member is formed by connecting four insole units. Therefore, the insole unit is preferably 20 cm to 40 cm in both length and width.
