Description

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. More specifically, the present invention relates to a lightweight cultivation floor for gardening which has excellent drainage properties.

[0002]

2. Description of the Related Art In recent years, gardening has become widespread in homes and parks, and many horticultural plants have been cultivated. In such gardening, it is necessary to form a well-drained horticultural cultivation floor.

[0003] As a method of draining the cultivation floor, generally, a porous drainage material is buried to form an underdrain, but in order to form the underdrain, civil works such as formation of a ditch are required. , It will take time and effort. In addition, when using a culvert, there is a problem that the drainage material is easily clogged and it is difficult to use the drainage material for a long time. Therefore, there is a demand for the development of a drainage plant cultivation floor that can be easily constructed and hardly causes clogging.

[0004] Further, when vegetation is vegetated on the slope, it is difficult to work on site, so it is desirable to prepare a cultivation floor in advance and lay it down, and the cultivation floor should have a structure that is easy to construct. desirable.

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. In such gardening, well-drained and lightweight horticultural cultivation is required. Floor is needed.

[0006] For this reason, there is a demand for a horticultural cultivation floor which is easy to produce, well drained, lightweight, and easy to transport and construct.

[0007]

SUMMARY OF THE INVENTION The present invention provides a horticultural cultivation floor which is excellent in productivity, well drained, light in weight and easy to carry and construct.

[0008]

Means for Solving the Problems The present invention has been made as a result of intensive studies in order 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 cultivation floor for gardening with excellent drainage characteristics, comprising forming a plate-like body having a plurality of recesses on the upper surface of the plate-like body, and mounting a cultivation soil for plant cultivation thereon. Is provided.

[0009] The present invention also provides a cultivation floor for horticulture with excellent drainage properties, wherein the soil for plant cultivation is filled in a concave portion on the upper surface of the plate-like body, and the effluent water, wherein the expanded synthetic resin particles are expanded polystyrene. The present invention provides a gardening cultivation floor having excellent drainage properties, wherein the expanded synthetic resin particles are spherical particles having a diameter of 3 to 15 mm.

Furthermore, the present invention provides the above-mentioned cultivation floor for horticulture with excellent drainage, wherein the cultivation soil for plant cultivation is coco peat, aquatic plant or perlite.

[0011]

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

As the foamed synthetic resin, 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, but generally, a chemical blowing agent such as dinitrosopentamethylenetetramine, p-toluenesulfonylhydrazide, azodicarbonamide, diazoaminobenzene, etc. 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 by 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-shaped body 2 in the present invention includes not only a typical plate-shaped body having a small thickness in the vertical and horizontal directions, but also a plate-shaped 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. However, in general, from the viewpoint of ease of construction and handling, 15 cm × 20 cm or more
It is about 200 cm × 300 cm. The thickness is 1-6
It is generally about 0 cm.

Concave portions 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 (A), a plurality of recesses 4 are provided on the upper surface of the plate-like body 1.
4 can be formed independently. FIG. 2 (B)
As shown in (1), the groove-shaped concave portions 4 and 4 can be formed in one direction.

The cultivated soil 5 is placed on the formed concave portions 4 and 4. In the present invention, cultivation soil is a material that widely vegetates plants, soil, sand, coco peat formed by loosening the bark, aquatic plants such as peat moss, fibrous materials such as sparrows,
Materials generally used for plant vegetation, such as perlite, zeolite, charcoal, and urethane foam, are meant.

FIG. 3 shows a method for placing the cultivation soil 5.
As shown in FIG. 3A, the upper surface of the plate-shaped body 2 may be covered entirely, or as shown in FIG. 3B, only the concave portions 4 and 4 may be filled.

When plants are vegetated using the horticultural cultivation floor 1 of the present invention, the platy body 2 is laid at the position where vegetation is to be laid, and then the cultivation soil 5 is put on the platy body 5 over the entire upper surface of the platy body 1. Or
By filling the recesses 4, 4, the preparation of the cultivation bed is completed. When the preparation is completed, vegetation is performed by sowing or planting seedlings at the positions corresponding to the recesses 4 and 4 of the plate-like body 2.

The cultivation may be applied after laying the plate-like body 2 as described above. However, when the shaped compost is used, the compost is previously loaded into the recesses 4 and 4 of the plate-like body 2. This may be laid.

[0023]

According to the present invention having such a structure, it is possible to form a horticultural cultivation floor with a light weight and simply by laying a plate-like body. Further, since the plate-shaped body has the concave portion, the side wall thereof is less likely to be clogged, and can exhibit the drainage function for a long time.

Further, in the present invention, since a plate-shaped body having shape retaining properties is used as a drainage material, plants grow and grow in height, and roots extend into the plate-shaped body to hold the plate-shaped body. It is possible to obtain a horticultural cultivation floor that does not fall down due to the wind.

Further, since it is formed by using the foam particles, it is possible to obtain a practical horticultural cultivation floor which has excellent heat insulating properties and also has a function of preventing a rise in the temperature inside the building when used on the roof of the building. Can be.
