Greening

The present invention is mainly related to greening rafts for construction of roof greening.

In recent years, as a result of the increase in urban greening and other demands, the technology for greening has been gradually developed and popularized in response to the planting of planting plants on the roof of buildings. This kind of roof greening cultivates plants on the roof of the building to soothe the absorption and divergence of heat from the roof, suppress the so-called Heat Island phenomenon, and also cultivate the plants on the roof of the building, trying to achieve Environmental improvement such as air pollution. Therefore, such a technique for roof greening, for example, the following Patent Document 1 and Patent Document 2 have been filed.

Such roof greening technology is generally divided into centralized management type greening and extensive greening. The so-called centralized management type greening is not only to suppress the heat island phenomenon, but also to pay attention to the construction of artificial gardens in order to maintain the aesthetics. Therefore, detailed maintenance is performed in a specific period, just like Centralized management becomes necessary.

In this regard, extensive greening is not as beautiful as centralized management greening, and it is sufficient from the point of view of expertise only, and maintenance is avoided as much as possible. From this point of view of maintenance, in the extensive greening, planting is the use of sedum plants that do not require irrigation water as the main plant.

In addition, the basis of planting of soil plants is to make plants grow well, and it is necessary to accumulate a certain thickness of soil. Compared with other plants, the thickness of the soil layer of the above-mentioned sedum plants can grow even if it is thin, so The roof does not need to carry a heavy stacking weight, and is most suitable for so-called thin-green planting species. It is also one of the reasons why sedum plants are mainly used for extensive greening.

For the technology related to thin layer greening, for example, the following Patent Document 3 is also filed. This patent document 3 is a patent application scope of the patent application filed in the patent document 3, and is a "multiple thin disk having a box type in which an upper portion is opened and previously planted in the thin disk, including evergreen unicorn grass. Thin green structure of green plants."

However, since the thin disk described in the above-mentioned reference 3 is used in the left-right direction of a plurality of installation surfaces laid on a roof or the like, it is not considered to form a structure that can be stacked vertically. Therefore, for example, when the plant-planting base material is preliminarily stored in a thin tray to be transported to the roof, a plurality of thin discs cannot be stacked and can be transported, and the transport efficiency is lowered. For this reason, in order to stack a plurality of thin disks, it is possible to carry them, and it is also prepared to use a shelf for stacking a plurality of thin disks, etc., and the use of such a dedicated shelf or the like has a need for a plurality of stacks.

The prior art documents include: Japanese Laid-Open Patent Publication No. 2003-143940, Japanese Patent Application Laid-Open No. Hei. No. Hei. No. Hei.

In order to solve these problems, an object of the present invention is to provide a greening pot, even if the planting plant is in a state in which the base materials of the stacked plants are planted in the upper and lower stages, the base materials and plants planted in the lower side of the plant are not used for the greening of the upper stage. Since it is smashed, it can be transported in a state in which a plurality of stacked plants are planted and can be efficiently transported to a place such as a roof.

In order to solve these problems, the present invention provides a greening raft having a plant-planting base material accommodating portion for accommodating a plant-based base material such as soil, characterized in that: a protrusion having a binding and fitting function is provided in the foregoing 钵In the state in which the protrusion body having the bonding and fitting function is used to secure the accommodation space of the plant-planting base material of the plant-planting base material accommodation portion, the body body can be stacked in a plurality of stages at the same time. The upper and lower adjacent crucible bodies are combined with each other in a state in which the plurality of stages are stacked; the protrusions having the combining and fitting functions do not ensure the plant-planting base material of the plant-planting base material accommodation portion when the aforementioned crucible body is not used. The accommodating space can be stacked on the upper and lower sides of the cymbal body, and the upper and lower cymbal bodies are fitted to each other.

In the structure of such a projection having a coupling and fitting function, for example, a projection having a coupling and fitting function is provided with a joint space portion for joining the upper and lower adjacent jaw bodies to each other in the side surface of the cartridge body. The fitting protruding portion is provided with a fitting protruding portion for fitting the fitting space portion in which the upper and lower adjacent dam main bodies are fitted to each other on the upper portion of the joining protruding portion.

In such a configuration, the fitting space portion and the joining space portion can be formed into a shape having a long axis portion and a short axis portion as viewed from the bottom surface, forming mutually similar shapes, and forming a slightly cross shape perpendicular to each other. Here, as for the shape having the long axis portion and the short axis portion, for example, a rectangular shape and an elliptical shape form a shape having a longer dimension of a shorter axis in the longitudinal direction. Therefore, for example, squares and circular systems are excluded.

The crucible body may have, for example, a shallow box-shaped disk shape formed by a bottom surface portion and a side surface portion formed to rise upward from the bottom surface portion. In this state, the height of the fitting projection is preferably higher than the height of the side portion of the body.

As described above, the greening enamel of the present invention has a protruding body having a bonding and fitting function, and therefore, when used, the state of the planting base material accommodating space of the plant-planting base material accommodating portion can be ensured, and The plurality of stacking bodies are stacked, and in the state where the plurality of sections are stacked, the upper and lower adjacent body bodies can be combined with each other, and when planting the planting base material and planting the plants in the plant planting base material storage part, the upper and lower adjacent body bodies are The protrusions having the binding and fitting functions are combined with each other, and the plants can be planted by stacking the plant-planting base materials in a plurality of stages.

In the state in which the greening rafts are stacked in a plurality of stages, in order to secure the accommodation space of the plant-planting base material in the plant-based base material accommodating portion, the plant-planting base material is preliminarily contained in the plant-planting base material accommodating portion, even if the plant is planted in the plant. The plurality of stacked greening rafts in the state of the base material are planted in the planting base material of the planting base material accommodating part of the greening hoe in the lower stage, and the plants planted in the planting base material of the plant are not used for the greening of the upper section.钵 垮 垮.

Therefore, the present invention can plant a plant such as a sedum plant and a low-thickness green planting plant in a planting base material in a planting base material accommodating part of the green planting raft, and carry it. Efficiency is carried out in a construction site such as a roof. In this way, even if the plurality of stacked green sheets are transported in a state of being used, the planting base materials and plants of the greening pots in the lower stage are not crushed by the greening of the upper stage, so there is no planting plant. Bad influence.

Further, when the cymbal body is not used, the above-mentioned protrusion having the function of bonding and fitting does not ensure the accommodation space of the plant-planting base material of the plant-planting base material accommodating portion, and can overlap the upper and lower plurality of stages, and can be vertically adjacent. In the case where the greening raft of the present invention is not used as a greening for a roof or the like, the green hoe for the planting of the base material accommodating portion can be accommodated in the planting base material accommodating portion. It will not overlap and overlap, especially when the greening is not used, it does not occupy the storage space.

Further, the fitting space portion and the joining space portion are formed into a shape having a long axis portion and a short axis portion as viewed from the bottom surface, forming a similar shape with each other, and forming a slightly cross shape perpendicular to each other, and the upper and lower portions are In the fitting space portion for the greening, the greening jaws of the upper and lower sections are fitted to each other so that the long-axis portion and the short-axis portion are formed in the same direction, respectively. In addition, when the greening of the upper and lower sections is overlapped, the greening of the upper and lower sections is used to form the intersecting direction of the upper and lower sections, and the greening of the upper and lower sections is not used. The fitting projections for forming the greening rafts of the lower stage are joined to the space for the joint of the green rafts of the upper stage.

In this case, since the fitting space portion and the joint space portion are formed in a similar shape to each other, the fitting projection portion of the greening raft for the lower stage is joined to the state of the space for the combination of the green raft for the upper stage. In the upper and lower sections of the greening, there is no sloshing between them.

Further, the crucible body is formed, for example, a shallow box-shaped disc shape formed by a bottom surface portion and a side surface portion formed up from the bottom surface portion, and the height of the fitting projection portion is formed at a height higher than a side surface portion of the crucible body. In the case where the fitting portion for the greening raft of the lower stage is joined to the space for the combination of the green rafts in the upper stage, there is a space for the plant-planting base material that can secure the plant-based base material accommodating portion. Effect.

In the case where the height of the fitting protruding portion is higher than the height of the side surface portion of the body, the top of the fitting protruding portion having a higher height than the side surface portion can be hung, for example, a net or the like. Even if the top of the fitting projection is hung on the net or the like, there is no advantage that the plant for planting thin layer greening or the like is caught in the net or the like.

For other purposes and functions of the present invention, please refer to the drawings and the embodiments, which are described in detail below.

Hereinafter, embodiments of the present invention will be described.

A cross-sectional view of the line, and Fig. 7 is a cross-sectional view taken along line CC of Fig. 1.

Since the greening tanning system of the present embodiment is used for roof greening, as shown in Fig. 1, the green body 1 of the greening body is formed into a flat square shape as a whole, and is versatile such as polyethylene or polypropylene. Made of synthetic resin. Further, the crucible body 1 is formed in a shallow box-shaped disk shape formed by the bottom surface portion 2 having a flat square shape and the side surface portion 3 formed by rising from the four sides of the bottom surface portion 2.

Therefore, the space portion surrounded by the side surface portion 3 is formed as a plant-planting base material accommodating portion 4 that accommodates a plant-planting base material such as soil. As for this soil, in addition to natural soil, light weight artificial soil can be used. Further, a product obtained by foaming a clay mineral such as pearlite (Pearlite) or the like may be used as a plant-based base material.

In the longitudinal direction and the lateral direction of the bottom surface portion 2 of the crucible body 1, two flat ribs 5 are slightly raised from the bottom surface portion 2, and a total of four flat ribs 5 are formed. At the intersection of the two flat ribs 5 in the longitudinal and lateral directions, the projections 6 having the coupling and fitting functions are erected. Since the above-described projections 6 having the engaging and fitting functions are erected at the intersection of the flat ribs 5, a total of four projections 6 having a bonding and fitting function are provided.

When the greening raft is used, the splicing body 1 can be stacked on the upper and lower sides in a state in which the accommodating space of the plant-planting base material of the plant-planting base material accommodating portion 4 is maintained, and In a state in which the plurality of stages are stacked, the upper and lower adjacent body bodies 1 can be combined with each other; and when not in use, the accommodation space of the plant planting base material of the plant planting base material containing portion 4 is not maintained, and the upper and lower plurality of stages can be overlapped. And the upper and lower adjacent body 1 can be fitted to each other.

In the above-described protrusion 6 having a bonding and fitting function, when the greening cymbal is used, the protruding protrusions 7 for joining the upper and lower adjacent dam bodies 1 in a state of being stacked in a plurality of stages; and not using greening When the crucible is used, the fitting projections 8 in which the plurality of stacking main bodies 1 are fitted to each other are fitted. The joint projection portion 7 and the fitting projection portion 8 are respectively formed into a substantially rectangular shape as shown in Fig. 1, and the joint projection portion 7 projects from the upper portion of the flat rib 5, and the fitting projection portion 8 is formed in a slightly ten-fold shape. The upper portion of the engaging projection 7 is extended in such a manner that the zigzag extends perpendicularly to the direction in which the engaging projection 7 is formed across the engaging projection 7. As shown in FIGS. 3 to 7, the position of the top portion 8a of the fitting projection portion 8 is higher than the top portion 3a of the side surface portion 3.

Therefore, as shown in FIG. 2, the joint protrusion portion 7 and the inner side surface of the fitting protrusion portion 8 form the joint space portion 9 and the fitting space portion 10, respectively. In the case of using the above-described greening raft, and the fitting when not in use, the joint space portion 9 and the fitting space portion 10 are used. As described above, the joint protruding portion 7 and the fitting protruding portion 8 are each formed in a substantially rectangular shape. Therefore, the joint space portion 9 and the fitting space portion 10 are formed in a substantially rectangular shape on the bottom surface, but the joint space is used. The portion 9 and the fitting space portion 10 are formed in a substantially rectangular shape similar to each other. More specifically, when this point is shown, as shown in FIGS. 6 and 7, the fitting protruding portion 8 is formed in a tapered shape from the lower portion to the upper portion, and the cross-sectional shape thereof is completely formed into a similar rectangular shape. Therefore, the top portion 8a of the fitting protruding portion 8 is joined to the joint space portion 9 for the greening raft on the upper side, and in the coupled state, the top portion 8a of the fitting protruding portion 8 is required to be used for the greening of the upper side. The fitting space portion 9 is formed in a non-sloshing state, and as a result, the fitting protruding portion 8 and the coupling protruding portion 7 are formed in a similarly rectangular shape, and thus the joint space portion 9 and the fitting space portion 10 are formed. They are formed into a slightly rectangular shape similar to each other.

Here, the inner diameter of the joint space portion 9 must be larger than the outer diameter of the proximal portion of the top portion 8a of the fitting projection portion 8 inserted into the joint space portion 9. In this case, it is desirable to obtain a combination without sloshing. Therefore, it is not appropriate that the inner diameter of the joint space portion 9 is larger than the outer diameter of the vicinity of the top portion 8a of the fitting projection portion 8, and it is desirable to have a slightly larger size. This means that the inner diameter of the joint space portion 9 is desirably smaller than the outer diameter of the lower portion of the fitting protrusion portion 8.

Further, in the center of the bottom surface portion 2, as shown in FIG. 1, the pedal portion 11 having a substantially circular shape protrudes from the bottom surface portion 2. The step portion 11 is a step which serves as a worker's foot when the plant-planting base material is placed in the plant-planting base material accommodating portion 4, for example, for maintenance, and when the plant is planted with the plant-based base material. From the pedal portion 11 toward the four projections 6 having the coupling and fitting functions, the elongated reinforcing ribs 12 are formed. Further, as shown in FIG. 2, on the inner surface side of the pedal portion 11, a reinforcing rib 13 which is slightly cross-shaped from the bottom surface is formed. As shown in FIG. 5, the lower end portion 13a of the rib 13 on the bottom surface side of the pedal portion 11 is close to the bottom surface portion 2. Further, as shown in FIG. 2, the reinforcing ribs 12 and 13 and the same reinforcing rib 18 are also formed on the inner surface side of the fitting protruding portion 8.

Further, in the side surface portions 3 on the four sides, the notch portions 14 through which the watering pipes are inserted are formed at two locations on each surface. As shown in FIGS. 3 to 7, the notch portion 14 is formed from the top portion 3a of the side surface portion 3 by a notch cut into a square shape. Further, as shown in FIG. 1 and FIG. 2, a tip insertion hole 15 for inserting and fixing a fixing tip or the like of a watering pipe inserted through the notch portion 14 is bored in the bottom surface portion 14a of the notch portion 14.

Further, a long hole 16 is bored in the top portion 3a of the side surface portion 3 on both sides of the notch portion 14. Since the long hole 16 is used arbitrarily, for example, after accommodating the plant-planting base material in the plant-planting base material accommodating portion 4, it is used for the purpose of inserting and fixing a fixing tip of the net covering the upper surface of the cymbal body 1. Further, a short flange 17 is formed outward at the top portion 3a of the side portion 3. Further, a hole 19 for drainage is bored in a portion of the boundary (contact) between the bottom surface portion 2 and the side surface portion 3 of the crucible body 1.

Therefore, as shown in FIG. 8, when the greening tamper 20 formed from such a structure is used, the plant-planting base material 21 containing the soil or the like is planted in the plant-planting base material accommodating portion 4 of the sputum body 1, and the plant 22 is planted on the plant. The base material 21 is planted, and in this state, as shown in the figure, the greening hoes 20, 20 are stacked one above another.

In this case, as shown in the figure, the top portion 8a of the fitting projection portion 8 of the greening raft 20 of the following paragraph is joined to the space for the joint space 9 of the green raft 20 of the upper stage, and the green raft for the upper stage is stacked. 20 The upper part of the greening 钵20 in the lower section. In this case, in the joint space portion 9 of the greening raft 20 of the upper stage, only the top portion 8a of the fitting protruding portion 8 is in a coupled state, so that the plant-planting base material accommodating portion 4 is provided in the plant-planting base material accommodating portion 4 as shown in Fig. 8 . The accommodation space for ensuring that only the plant-planting base material 21, and the planting plant 22 are accommodated is formed.

In this way, in order to ensure that only the plant-planting base material 21 and the storage space of the planting plant 22 are accommodated, the top portion 8a of the fitting space portion 10 of the greening raft 20 of the lower stage is joined to the greening hoe 20 for the greening of the upper stage. In the space portion 9 for the combination, the greening raft 20 of the upper stage is stacked on the upper portion of the green tamping 20 of the lower stage. As shown in Fig. 9, the green hoe 20 is stacked in the upper and lower stages, and the green hoe 20 is also disposed on the left and right sides.

In the state in which the greening rafts are stacked in a plurality of stages, as described above, the accommodation space of the plant-planting base material of the plant-planting base material accommodating portion 4 is secured, so that even if the plant-planting base material 21 is previously accommodated in the plant-planting base material accommodating portion 4, The planting planting base material 21 in the planting base material accommodating portion 4 of the greening hoe 20 of the lower stage is planted in the planting planting base material 21, and the planting planting base material 21 in the planting base material accommodating portion 4 of the greening hoe 20 of the lower stage is planted in The plant 22 in the plant-planting base material 21 is not crushed by the greening stalk 20 of the upper stage. Therefore, plants such as sedum plants and low-thickness green plants can be planted and transported in a planting base material of a plurality of green planting base material storage units stacked in a plurality of stages, and can be efficiently transported. The effect of carrying it to a place such as a roof. In addition, even if the planting of the greening rafts is carried out in a plurality of stages, the planting base materials and plants of the greening hoes on the lower side are not crushed by the greening of the upper stage, so they are not planted. Plants have adverse effects.

In particular, since the position of the top portion 8a of the fitting protruding portion 8 is higher than the top portion 3a of the side surface portion 3, it is easier to secure the plant-planting base material of the plant-planting base material containing portion 4 in a state in which the greening raft is stacked in a plurality of stages. The accommodation space.

Furthermore, as shown in FIG. 9, in the state in which the plant-planting base material 21 is accommodated in the plant-planting base material accommodating portion 4, since the pedal portion 11 is exposed from the surface of the plant-planting base material 21, the greening is stacked in a low number of stages. In the case of the 钵20, the planting planting base material is accommodated in the plant-planting base material accommodating portion 4, for example, maintenance, and the planting plant base material is planted, and the pedal portion 11 can be used as the step of the operator's foot. Use.

On the other hand, when the greening hoe 20 is not used for the landscaping of the roof portion, as shown in Fig. 10 and Fig. 11, the fitting protruding portion 8 of the green hoe 20 of the following stage is fitted to the green hoe 20 of the upper stage. In the fitting projection portion 8, the greening raft 20 of the upper section is stacked on the upper portion of the greening hoe 20 of the lower stage. As shown in the figure, in this case, the accommodation space of the plant-planting base material 21 of the plant-planting base material accommodating portion 4 is not maintained, and the upper and lower plurality of stages can be overlapped, and at the same time, the landscaping for arranging up and down can be used. When it is used for the greening of the planting base material accommodating part 4, it is not possible to increase the use of the planting base material accommodating part 4. The volume of the way to make it overlap, when not using the greening raft, it does not occupy the storage space.

As described above, in the present embodiment, the fitting protruding portion 8 having the fitting space portion 10 on the inner surface side and the joining protruding portion 7 having the joining space portion 9 on the inner surface side are combined and embedded. Since the functioning projections 6 are provided in the dam main body 1, when the green hoe 20 is used, the storage space of the plant cultivating base material 21 can be secured, and the plurality of stacked green hoes 20 can be efficiently transported and then transported. When the greening hoe 20 is not used, it is superimposed so as not to increase the volume of the empty greening shovel which is not contained in the plant-planting base material accommodating portion 4, and can be stored without occupying space.

Further, in the above embodiment, the crucible body 1 is formed in a planar square shape, but the shape of the crucible body is not limited to the above embodiment, and the shape is not specified. Further, in this embodiment, the crucible body 1 is made of a synthetic resin such as polyethylene or polypropylene, but the material of the crucible body 1 is not limited to this embodiment. For example, a synthetic resin other than the above may be used, and a material other than the resin may be used. For example, a metal such as aluminum may be used.

Further, the types of plant-based base materials are not limited to natural soils and artificial soils, and clay minerals such as perlite may also be used.
