DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a horticultural cultivation floor using a foamed synthetic resin, and more particularly to a lightweight horticultural cultivation floor having excellent drainage properties.

[0002]

2. Description of the Related Art In recent years, there has been a strong demand for greening the roof of a building for reasons such as air purification and prevention of the occurrence of heat islands. Is required.

[0003] In addition, the roof of a building is often exposed to strong winds, and in order to prevent the lodging of the plants, a cultivation floor capable of holding the plants stably is required. Drainage is good, but on the other hand, water retention is also required to grow plants.

Further, from the viewpoint of preventing the occurrence of heat islands, it is desirable that the cultivation floor has excellent heat insulation.

[0005] For this reason, there is a need for a horticultural cultivation floor which is excellent in heat insulation, drains well, and on the other hand, has excellent water retention for plant cultivation and can prevent lodging of plants.

[0006]

SUMMARY OF THE INVENTION The present invention provides a horticultural cultivation floor which is excellent in productivity and heat insulation, has good drainage and water retention, is lightweight, and can be easily transported and constructed.

[0007]

Means for Solving the Problems The present invention has been made as a result of diligent studies to achieve the above object. Specifically, the present invention has been made by bonding expanded synthetic resin particles with a bonding agent to form a gap between the particles. A plurality of recesses are formed on the upper surface of the plate-shaped body while forming a plate-shaped body having water, and a water retention material is filled in a container capable of storing water, and the container is loaded into the recessed portion. The present invention provides a cultivation floor for horticulture, wherein a cultivation soil is placed on the cultivation floor.

Further, the present invention provides the horticultural cultivation floor wherein the expanded synthetic resin particles are spherical particles having a diameter of 3 to 15 mm, the horticultural cultivated floor wherein the expanded synthetic resin particles are expanded polystyrene, and a water retention material. But pumice, Akadama, Kanuma, shells,
Alternatively, the present invention provides the horticultural cultivation floor, which is perlite, and the horticultural cultivation floor, wherein the container is made of a synthetic resin.

BEST MODE FOR CARRYING OUT THE INVENTION As shown in FIG.
Are formed using a bonding agent.

Examples of the foamed synthetic resin include styrene-based resins such as polystyrene, impact-resistant polystyrene and ABS resin.
Alternatively, polyethylene, ethylene / vinyl acetate copolymer, polypropylene, polyester, polycarbonate, polyamide and the like can be used. These synthetic resins can be colored as needed.

The method for forming the expanded synthetic resin particles 3 and 3 is not particularly limited. Alternatively, foamed synthetic resin particles 3 and 3 can be obtained by heating and foaming synthetic resin particles kneaded or impregnated with a physical foaming agent such as a volatile hydrocarbon such as propane, butane, or pentane or a halogenated hydrocarbon. it can.

A resin obtained by kneading the above-mentioned chemical or physical foaming agent or a resin obtained by kneading nitrogen, carbon dioxide or the like under high pressure is extruded into a strand shape using an extruder and foamed. Can be obtained by cutting into pellets. Among them, propane,
So-called pre-expanded particles obtained by foaming volatile hydrocarbons such as butane and pentane, or polystyrene particles impregnated with halogenated hydrocarbons with steam are preferred.

As the bonding agent for bonding the expanded synthetic resin particles 3, 3, any bonding agent having water resistance may be used, but asphalt, vinyl acetate adhesive, or rubber adhesive is used. Etc. can be used.
The size of the expanded synthetic resin particles 3 is generally a particle having a diameter or a side of 3 to 15 mm, and among them, spherical particles are preferable.

In the present invention, the shape of the plate-like body 2 is arbitrary, and the thickness can be arbitrarily selected. Therefore, the plate-like body in the present invention includes a typical plate-like body having a small thickness in the vertical and horizontal directions, and a plate-like body having a large thickness, which is generally called a block. The size of the plate-like body 2 is determined according to the purpose, particularly the size of the plant to be cultivated.
From 15cm x 20cm to 2 for ease of handling
It is about 00 cm x 300 cm. The thickness is 1cm ~
About 60 cm is common.

As shown in FIG. 2, recesses 4 and 4 are formed in the upper surface of the plate-like body 2 formed by combining the expanded synthetic resin particles 3 and 3.

Although the shape of the concave portion is arbitrary, for example, FIG.
As shown in FIG.
Can be formed independently, and as shown in FIG. 2B, the groove-shaped concave portions 4 can be formed in one direction.

A water retention material 7 filled in a container 6 capable of storing water is loaded in the formed concave portions 4 and 4. The material for forming the container 6 is not particularly limited, and metals, ceramics, thermoplastic resins, and the like can be used. Among them, a thermoplastic resin is preferable, and as the thermoplastic resin, polystyrene, high-impact polystyrene is used. , ABS
A styrene resin such as a resin, or a polyolefin such as polyethylene, ethylene / vinyl acetate copolymer, or polypropylene, as well as polyester, polycarbonate, and polyamide can be used.

These thermoplastic resins can be molded by injection molding, blow molding, vacuum molding or the like, and the synthetic resin can be colored if necessary.

The container 6 has a shape following the shape of the concave portion 4 of the plate-like body 1, and FIG. 3 is formed in a bottomed cylindrical shape.

The container 6 is filled with a water retention material 7. The water retention material 7 used in the present invention includes soil, sand, pumice,
Akatama soil, Kanuma soil, shells, perlite, zeolite, charcoal, urethane foam and the like having excellent water retention properties are used.

Among them, pumice, akadama soil, Kanuma soil, shells, and pearlite powders are preferred. By filling the shaped material, handling such as transportation can be facilitated.

When plants are vegetated using the horticultural cultivation floor 1 of the present invention, a container 6 filled with a water retention material 7 is loaded into the recesses 4, 4 of the plate 2, and a cultivation soil 8 is placed above the container 6. Is placed, and the plant 9 is sown or planted on the soil 8.

The cultivation soil 8 used in the present invention broadly refers to a material for vegetation of plants, such as soil, sand, pumice, Akadama soil, Kanuma soil, shells, perlite, coco peat formed by loosening the bark, It refers to materials generally used for plant vegetation, such as aquatic plants such as peat moss, fibrous materials such as palms, zeolite, charcoal, and urethane foam.

In this way, excess rainwater is guided by the plate-like body 2 and drained, and water necessary for growing the plant is removed from the water held in the container 6 by capillarity. Supplied to

[0025]

According to the present invention having such a constitution, it is possible to form a horticultural cultivation floor which is excellent in water supply to plants and well drained against excessive rainwater. In addition, since the plate-like body is composed of a combination of foamed particles, clogging hardly occurs and a drainage function can be exhibited for a long period of time.

Furthermore, since it is formed into a rigid plate shape using the foam particles, when used on the roof of a building, the plants do not fall down due to strong winds, are excellent in heat insulation, and have excellent heat insulation properties. It is possible to obtain a practical horticultural cultivation floor that also has a function of preventing a rise in temperature.
