Hereinafter, the structure and operation of the present invention will be described in more detail with reference to the accompanying drawings. In describing the present invention, terms and words used in the present specification and claims are to be construed in accordance with the principles of the present invention, on the basis that the inventor can properly define the concept of a term in order to best explain his invention It should be construed as meaning and concept consistent with the technical idea of.

1 and 3, the modules 10 and 10a for artificial soil recording according to the present invention include a water reservoir 11, a connection top plate 12, a module coupling unit 15, The drainage channel 17, and the seat 14 in common. For the sake of convenience, the same reference numerals are assigned to common components.

First, a first embodiment (basic example) will be described with reference to Figs. 1 and 2. Fig.

The artificial soil recording module 10 of this embodiment has a bottom surface 11a and a plurality of water storage tanks 11 each formed by a cross wall 11b erected along the peripheral edge of the bottom surface 11a, A connecting upper plate 12 extending in the shape of a cross connecting the upper ends of the water storage tanks 11 of the water tank 11 and a peripheral upper surface of the lower water tank 11 and the connection upper plate 12, A module coupling portion 15 formed at the upper end of the peripheral wall 16 and closely fitted to the peripheral wall 16 of the adjacent module 10 and connected to the lower portion of the connection top plate 12; A drain channel 17 formed along the extension direction of the upper plate, and a seat 14 mounted on the upper surface of the connection upper plate 12. [

A reinforcing support 18a disposed between the base end portion of the connection upper plate 12 and the inner side of the circumferential wall 16 and a reinforcing supporter 18 protruding from the lower surface of the connection upper plate 12 18b.

The module 10 of the present embodiment has a rectangular container shape. The container-shaped module 10 basically functions as a boundary for separating the artificial soil portion such as a roof and the vegetation soil. As shown in FIG. 2, And the planting layer 19, which is a growth medium for the plant. That is, as shown in FIG. 2, in the module 10 of the present embodiment, the planting layer 19 is filled in the space (including the water storage tank 11) formed inside the peripheral wall 16, So that various plants grow.

The module 10 of the present embodiment has a plurality of water storage tanks 11 arranged in a lattice form and a drainage channel 17 is formed between the water storage tanks 11 . The module 10 of the present invention is connected to the drainage port 17 through the drainage port 17. The drainage port 17 is connected to the drainage port 17 through the connection top plate 12, 121 are formed in a closed structure.

The water storage tank 11 is designed to store water and is designed to meet the rainfall conditions of Korea, which has a flood season and a dry season. That is, in the case of the water storage tank 11, the soil forming the planting layer 19 is filled with water that flows into the soil located in the upper part of the connecting top plate 12, The water is drained to the outside through the drain hole 121 and the water impregnated into the lower portion of the connection top plate 12 is held in the pores of the soil filled in the water storage tank 11. A simple analysis of the water balance for the main rooftop green grass reveals that there is sufficient water supply between April and September, but water that is not actually stored in the planting layer (19) leaks out, Effective moisture is far less than that.

Therefore, the presence of the water reservoir 11 implemented in the module 10 of the present embodiment can be said to be very useful. As a result, the module 10 of the present embodiment performs smooth drainage and a sufficient water-storage function at the same time, so that it is not necessary to construct a separate drainage layer and a low-water layer, which are required in the existing rooftop greening technology.

When the module 10 is connected to the drainage channel 17, the drainage channel 17 functions as a drainage pipe extending in all directions. Therefore, even in the case of intensive rainfall, the water flows directly through the drainage port to the waterproof layer, In addition, since the flow of air through the drain channel 17 is free, it helps root rooting of the plant planted in the module 10, and the presence of such an air layer greatly alleviates the heat exchange between the building and the surrounding environment through the module.

Preferably, in the module 10 of the present embodiment, the drain channel 17 is 200% wider than a conventional similar structure so as to serve as a drain hole for allowing water exceeding the storage capacity at the time of rainfall to rapidly exit, Of the total floor area of the module is 60% of the total floor area of the module. In the period when water does not flow, more than 60% of the total floor area of the module between the roof top and the module will float without contact, and an air layer will be formed therebetween. Therefore, the "improvement of the thermal environment by rooftop greening Research "(Furukawa Nobuhisa, University of Tokyo, Japan). As reported in the International Symposium on Greening of Rooftops in Korea and America (Seoul, Korea, 2003), the insulation effect is better than when the whole area is filled with soil.

In addition to the insulation effect, the existence of the drainage channel 17 reduces the amount of soil material by 60%, thereby greatly alleviating the burden due to the building load. Also, in terms of the amount of soil material, it is possible to save about 60% (by volume) of the soil in the channel structure module, and to reduce the load burden thereof, This has a greater effect when the planting layer 19 contains water as shown in Fig. Therefore, it can be seen that the module 10 in which the drain channel 17 of the present embodiment is implemented has a remarkable technical difference from the block or box structure having a narrow drainage passage of the conventional partitioning type.

Further, preferably, the total area of the drain holes 121 occupies about 4-5% of the entire plane of the module (which means the floor area occupied by the module in this specification), so that the surplus water quickly flows into the drainage channel 17 It is reasonable to be able to escape to.

Therefore, there is no fear of disturbance of planting soil due to inundation and poor drainage even in extreme heavy rainfall. In the case of rooftop greening, most of the materials used as planting soil are small in artificial lightweight soil, which causes flooding of planting layer (19) during flooding. Therefore, rapid drainage of surplus water is very important condition for rooftop greening module.

Meanwhile, a soil material having a small particle diameter can be drained through the drain hole 121 formed in the connection top plate 12, and the roots of the plant growing in the plant material layer 19 extend out of the module through the drain hole 121, There is a high possibility of causing damage to the apparatus.

In order to solve this problem structurally, the connecting top plate 12 is provided with a seat 14 so that the water can be passed through the drain 121 and the functions of blocking and ventilating the fine soil can be expressed. (Water) and the air layer are simultaneously performed by passing only water through the sheet 14 having a gap smaller than the drain hole 13 and blocking the fine soil and roots.

In other words, since the conventional technology can not solve this problem structurally, it is mentioned in the specifications that the filtration layer and the air layer are separately laid out, which limits the efficiency and convenience of the construction. Therefore, as in the present embodiment, the module 10 equipped with the seat 14 having the filtration and navigation function can be provided with the module 10 without additional work and immediately filling the planting layer 19 to plant the plant Alternatively, the rooftop recording can be performed only by directly installing the plant in the module 10 in the field, which enables quick and simple construction compared to the conventional rooftop greening technology.

In the present invention, when the sheet 14 is attached to the connection top plate 12, it can be attached by a primer, but when the primer is attached by the primer, the gap of the sheet 14 is filled, The performance of the module 10 of the present invention may be deteriorated.

Thus, in this embodiment, the connection upper plate 12 is provided with a groove-like mounting groove 122 and an insertion protrusion 123 as a sliding movement protrusion. That is, the seat 14 is placed in the mounting groove 122 and the insertion protrusion 123 is inserted into the fastening hole 141 formed in the seat 14, so that the seat 14 is slid from the connection upper plate 12 .

The reason for such construction is that when the planting layer 19 is filled and used in the module 10 of the present embodiment, the soil of the planting layer 19 is shrunk during the dry season, Stress may be applied to the seat 14 to cause lifting of the seat 14. This lifting may cause leakage of the soil and penetration of the root into the drain hole 121.

Thus, in the present embodiment, the connection groove 122 and the insertion protrusion 123 are formed on the connection upper plate 12, and the coupling hole 141 is formed on the seat 14. In addition, the reinforcement support 18a, So that the fastening hole 142 is formed.

The module connecting portion 15 is formed at the upper end of the peripheral wall 16 to prevent separation and warping when the modules 10 are coupled to each other and is in contact with the peripheral wall 16 of the adjacent module, . That is, the female engaging portion 151 and the male engaging portion 152 are respectively formed, and fastening between the modules 10 is performed by the forced fitting method.

Next, the second embodiment will be described with reference to FIGS. 3 and 4. FIG.

The artificial soil recording module 10a of the present embodiment also has a bottom surface 11a and a plurality of water storage tanks 11 formed by intersecting walls 11b provided upright along the peripheral edge of the bottom surface 11a, A connecting upper plate 12 extending in a cross shape connecting the upper ends of the water storage tanks 11 and a connecting upper plate 12 formed at the upper end of the rim of the latticed structure formed by the water storage tank 11 and the connecting upper plate 12, A module connecting portion 15 for allowing the module 10a to be fastened to the connecting top plate 12, a drain channel 17 formed along the extending direction of the connecting top plate below the connecting top plate 12, As shown in Fig.

However, unlike the embodiment shown in Fig. 1, the present embodiment does not have the constitution of the peripheral wall 16, and as shown in Fig. 4, the modules 10a of the present embodiment are assembled, And the boundary edge 16a is provided separately as the peripheral wall 16 does not exist while the food material layer 19 is formed on the upper part.

Also in this embodiment, the connection top plate 12 is provided with a drain hole 121, a mounting groove 122 and a slip resistant wall, which are optional in the case of the drain hole 121 or formed in a part of the connection top plate 12 As shown in FIG. 3, a plurality of drain holes 121 are formed parallel to each other in the lattice-shaped connection upper plate 12, and the mounting groove 122 is also formed into a bar-shaped groove.

3, the sheet 14 is formed in a bar shape. In the case of the slip ring, the sheet 14 is also constituted by a plurality of engagement ends 124 protruding from the upper end of the attachment groove 122 and contacting the sheet 14 So that the sheet 14 is fixed by the plurality of latching ends 124 while being placed in the mounting groove 122.

In this embodiment, the flow path 125 is formed in the connection top plate 12 so that the adjacent water reservoirs 11 communicate with each other. The flow path 125 includes a drain hole 121 Is formed in the connection upper plate (12) which is not formed, so that water can easily flow between the water storage tanks (11).

The reason for configuring the flow pathway 125 is that the water introduced into the module 10a from the upper portion of the connecting top plate 12 is drained to the outside through the drain hole 121 and flows into the lower portion of the connecting top plate 12 The inflow water is stored in the pores of the soil. Depending on the case, depending on the difference in the gap leading to the flow of water in the soil above the connection upper plate 12, Excessive inflow of water into the water storage tank 11 may occur.

Such excessive inflow of water may cause floating of the soil at the portion. In this embodiment, the flow path 125 is formed so that the water flowing into the lower portion of the connection upper plate 12 can flow the water between the water storage tanks 11 And to solve the problem of structural integrity deterioration which may be caused by non-uniform water storage.

In the present invention, the module 10 or 10a may be made of various materials, but in the present invention, it is preferable that 2 to 10 parts by weight of the isocyanate compound, 30 to 60 parts by weight of the silica powder, 10 to 20 parts by weight of titanium, 5 to 10 parts by weight of aluminum oxide, 1 to 3 parts by weight of a thickener, 1 to 3 parts by weight of pigment, 3 to 5 parts by weight of sodium lauryl sulfate and 0.5 to 1 part by weight of catechin An example is shown in which the module 10, 10a is manufactured.

First of all, the polyethylene resin is used as a main component of the composition. The polyethylene resin is excellent in chemical resistance and cold resistance, has excellent impact resistance, and has a semi-permanent life. More preferably, it is preferable to use a high density polyethylene (HDPE) resin.

The isocyanate compound is used as a curing agent. When the isocyanate compound is blended below the blending range, the blending property is lowered. If the blending range is exceeded, the appearance is defective.

The silica powder reinforces the strength by acting as a filler in the composition. In particular, since the silica has a plurality of voids formed therein, the modules 10 and 10a function not only as a deodorant but also as a heat insulating layer, To block the transmission of heat between the structure of the inner structure 19 and the inner structure layer 19.

The titanium dioxide is blended as a photocatalyst. The titanium dioxide itself exhibits a photo-oxidation effect by ultraviolet rays and does not emit secondary pollution by-products such as gas. Particularly, . That is, the oxidation of the modules 10 and 10a as well as the waterproof layer of the structure is prevented by the oxidation by the organic material.

The reason why the titanium dioxide is limited to the above-mentioned blending range is that if the blending range is exceeded, there is a problem such as a decrease in strength due to a change in the physical properties of the other composition due to the photooxidation reaction of titanium dioxide.

However, in the case of mixing only the titanium dioxide, there is a problem that the function of self-purification can not be realized when the amount of light irradiation is insufficient in the wet season and the shade. If such a self-cleaning function is not properly implemented, harmful organic matter may be released, which may also cause deterioration.

The aluminum oxide is blended with a phosphorescent pigment in addition to titanium dioxide in addition to titanium dioxide. The aluminum oxide is blended as a phosphorescent pigment. When the light irradiation amount is insufficient in the wet season or the like, the self-purification function of the titanium dioxide is continuously .

The aluminum oxide has a spinel structure and is a composition having no emission of harmful harmful substances to the human body, having a long luminescence time (maximum afterglow time of 2,000 minutes) and having excellent weather resistance. That is, the aluminum oxide has such a constitution as to complement the continuous expression of the self-cleaning ability of the titanium dioxide by using afterglow when the light irradiation amount is insufficient. The reason why the compounding ratio of aluminum oxide is limited is as described above for reasons of afterglow effect, strength drop, stable dispersion with other composition, and the like.

The thickener is added to the above-mentioned composition in the form of a curing agent, and in addition, a thickener is added to increase the moldability. A known thickener composition can be used. In consideration of moldability and filling property, .

Further, microbubbles are also formed in the matrix of the polyethylene resin or the like in the composition, so that the entire module 10, 10a functions as a heat insulating layer. To this end, 3 to 5 parts by weight of sodium lauryl sulfate is added to 100 parts by weight of the polyethylene resin.

Sodium lauryl sulfate allows fine bubbles to be formed in the matrix. When the amount is less than 3 parts by weight, the effect of generating microbubbles is insignificant. When the amount is more than 5 parts by weight, the microbubbles are excessively generated, will be.

However, even if sodium lauryl sulfate is added in the above mixing range, bubbles having a comparatively large particle diameter can be inherent to the matrix due to microbubbles bond. Such large-sized bubbles may cause a decrease in strength of the coating layer, The air bubbles are likely to be blown out, and the gas may be discharged thereby causing problems such as internal oxidation and oxidation of the waterproof layer.

In the composition, 0.5 to 1 part by weight of catechin is added to 100 parts by weight of the polyethylene resin to prevent oxidation that may occur in the matrix, thereby causing a problem of durability deterioration of the modules 10 and 10a itself To be controlled.

On the other hand, the non-woven fabric having a gap smaller than that of the drain hole 121 can be used for the sheet 14. On the other hand, when only general non-woven fabric is used, moisture content is maintained by the internal gap. The corrosion of the nonwoven fabric may be caused by corrosion of the nonwoven fabric. Such corrosion may be caused by the tearing and lifting of the sheet 14 due to the deformation of the planting layer 19, There is a problem that can not be.

Accordingly, the present invention provides a sheet 14 that is prepared by coating or impregnating a nonwoven fabric with a composition containing green tea extract. The reason for using the sheet 14 prepared by coating or impregnating the nonwoven fabric with the green tea extract composition is to prevent the nonwoven fabric from being oxidized due to the presence of the catechin ingredient in the green tea extract.

The green tea extract contained in the composition can be obtained by using various extraction methods known in the art, and is preferably (a) water, (b) an anhydrous or hydrated lower alcohol having 1 to 4 carbon atoms (methanol, ethanol Propanol and butanol), (c) a mixed solvent of the lower alcohol and water, (d) acetone, (e) ethyl acetate, and (f) chloroform as an extraction solvent. If necessary, it can be obtained after the above-mentioned solvent treatment by an additional purification process.

In addition, the present invention further provides an example in which aluminum powder and activated carbon powder are included in the composition containing the green tea extract.

The reason for including the aluminum powder is to suppress the growth point of the myocardium in the plant growing in the planting layer 19 of the modules 10 and 10a and to allow the root roots to move into the planting layer 19, (14) and the drain hole (121) so as to prevent the waterproof layer and the structure from being staked.

The reason why the activated carbon powder is further added is to prevent the waterproof layer from being deteriorated by carbon dioxide gas or the like by adsorbing carbon dioxide gas or the like discharged from the root of the plant.

That is, the aluminum powder and the activated carbon powder are intended to further double the function of the sheet 14 as an air layer.

On the other hand, when the water flowing into the modules 10 and 10a is discharged through the drain port 121 and the water is supplied through the water storage tank 11 but the water is excessively introduced during rainfall or the like, There may arise a problem such that the plant material 19 is separated from the plant material layer 19 because the plant material layer 19 is made up of lightweight artificial soil and floated.

In the present invention, as shown in FIG. 5, the water reservoir 111 is placed in at least one of the plurality of water storage tanks 11 so that sufficient water storage space can be secured. A plurality of flow holes 111-2 are formed in the outer shell 111-1 and a plurality of flow holes 111-2 are formed in the outer shell 111-1 The outer sheet 111-3 is formed of the same material as that of the sheet 14 to prevent the fine soil from flowing into the outer shell 111-1 by the outer sheet 111-3 So that the water in the food material layer 19 is allowed to flow so that the inflow water can be stored in the water storage space inside the shell 111-1.

It is preferable that the outer shell 111-1 is opposed to the shape of the water reservoir 11. The outer shell 111-1 is formed in a hexagonal shape communicating with the outside by the flow hole 111-2, So as to be fastened.

In the water storage tank 11, water is stored by the pores of the soil, but the water storage tank 111 is provided with a water storage space inside the shell 111-1 so that a sufficient water storage space is assured. By storing water in the water reservoir 111, it is possible to prevent floating of the planting layer 19 by securing a sufficient water storage space at the time of rainfall or the like. In the dry season, moisture can be re-introduced into the planting layer 19 So that no separate care is required.

The number of the water storage pools 111 to be installed in the water storage tank 11 can be selectively selected in consideration of the type of plant to be grown and the natural environment so that the size of the modules 10 and 10a can be fixed, It is possible to do.

It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit or scope of the invention. Therefore, the technical scope of the present invention should not be limited to the contents described in the detailed description of the specification, but should be defined by the claims.
