DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a folded roof greening system.

[0002]

2. Description of the Related Art As a greening technique for folded roofs,
There has been proposed a structure in which a support plate for raising the bottom is installed in a valley of a roof folded plate, a medium is arranged on the support plate in the valley, and a plant is cultivated in this medium (Japanese Patent Application Laid-Open No. HEI 7-1995). -111829).

Further, a plant cultivation container having a predetermined length containing a medium for plant cultivation is oriented in a horizontal direction orthogonal to the direction of the folding plate, and a special installation member is used on the mountain of the roof folding plate. There has also been proposed one in which the mounted and folded roof is greened (Japanese Patent Laid-Open No. 8-266173).

[0004]

However, in the former method, installation of a support plate, arrangement of a medium on the support plate, and planting must be performed on a roof. In addition, there is a trouble in planting that the planting on the roof must be managed in the early stage of development. Further, since the support plate only supports the culture medium from below, there is also a problem that the culture medium comes into direct contact with the roof folding plate, and the folding plate is easily corroded.

[0005] Since the latter uses a plant cultivation container, the culture medium is previously stored in the cultivation container, planting is performed, and the plant may be placed on the roof. Is less. Further, since the culture medium is contained in the cultivation container, and the container is disposed above the folded mountain, the roof folded plate does not corrode. However, on the other hand, since the cultivation container is installed in the horizontal direction orthogonal to the folding flow direction, the installation must be performed using a special installation member, and the installation work is troublesome. Not only that, the whole cultivation container projects above the top of the roof folded plate, so that the cultivation container is easily affected by wind pressure. Therefore, a strong mounting structure that can withstand the wind pressure is used for mounting the container. It is necessary and the cost is high and it is easy to come with it.

In view of the above problems, the present invention has little difficulty in planting, hardly corrodes a folded plate, and can easily perform installation work on a folded roof. Another object of the present invention is to provide a folding roof greening system which is hardly affected by wind pressure.

[0007]

An object of the present invention is to provide a plant cultivation container having a predetermined length containing a medium for plant cultivation, the length direction of which is directed to the flow direction of the roof fold, and Of a folded roof, characterized by being set protruding into the valley.

That is, since a plant cultivation container is used for greening a folded roof, a method can be adopted in which a culture medium is stored in advance in a cultivation container, planting is performed, and the medium is placed on the roof. There is little difficulty in planting, and planting can be easily performed in terms of construction and management.

In addition, since the planting container is used as described above, the culture medium does not directly come into contact with the roof folded plate, and the folded plate is hardly corroded.

[0010] In addition, the cultivation container is set so as to protrude into the valley on the upper surface of the folded roof with the length direction thereof oriented in the flow direction of the roof folded plate.
The protrusion above the roof folded plate can be reduced or eliminated, and the effect of wind pressure on the cultivation container is reduced or eliminated, and the cultivation container is installed on the roof folded plate with a simple structure. can do.

When the cultivation container is set on the roof folded plate, a ventilation space is formed between the surface surrounding the folded valley and the plant cultivation container. And the folds can be dried, thereby further preventing corrosion of the folds.

[0012] Further, the above-mentioned plant cultivation container may be provided with projections for forming a space provided on both side surfaces thereof or both side surfaces thereof.
It is good to install it in contact with the slopes on both sides surrounding the origami valley. With such a structure, the plant cultivation container is automatically placed at a predetermined appropriate position in the lateral direction orthogonal to the folding plate flow direction within the valley simply by fitting the cultivation container into the folded valley. Positioned, the installation work of the cultivation container on the roof can proceed efficiently and properly. Moreover, since the cultivation container is supported from both sides by the two slopes in the folded plate valley, the cultivation container itself does not need to have high strength at that portion.

In the case where the plant cultivation container is provided with outwardly projecting portions on both sides thereof and the outwardly projecting portions are supported on the top of the folded plate hill portion, the mechanical strength of the container portion in the folded plate valley portion is increased. The burden on the cultivation container can be reduced, and undesired deformation due to the weight of the cultivation container can be prevented. Not only that, the lower surface of the outwardly protruding portion and the both sides of the plant cultivation container, or the space forming protrusions provided on both sides of the plant cultivation container cooperate to fold the plant cultivation container. With simple operation just to fit in the valley,
The cultivation container can be set in a proper installation posture, and the construction can be further facilitated.

[0014]

Next, embodiments of the present invention will be described with reference to the drawings.

In the greening system of the first embodiment shown in FIGS. 1 and 2, reference numeral 1 denotes a roof folding plate, and reference numeral 2 denotes a plant cultivation container. The folded plate 1 has a relatively large height dimension, for example, about 150 mm.

The plant cultivation container 2 has a predetermined length,
The length direction thereof is directed to the flow direction of the roof folded plate 1 and is installed in the folded plate valley portion 1a. The height size of the entire container in the height direction of the container is the valley of the roof folded plate 1. It is designed to fit within the part 1a.

The container 2 has a bottom wall 2a and both side walls 2a.
b, 2b are formed in an inverted trapezoidal cross section along three surfaces surrounding the inside of the valley 1a of the folded plate 1, and as shown in FIG. 2 (b), the lower surface of the bottom wall 2a of the container 2, And both side walls 2b, 2
b are provided on the outer surface at intervals in the longitudinal direction, and these convexes 4... are brought into contact with three surfaces surrounding the inside of the folded valley portion 1a, so that the container 2 and the folded valley are arranged. The space part 5 for ventilation is formed between the surface surrounding the part 1a.

The cultivation container 2 may be made of various resin materials such as plastics, and among them, it is preferable to use lightweight, durable and inexpensive styrene foam. A silicon material or the like may be used. The bottom wall 2a of the cultivation container 2 is preferably provided with holes 3 for removing excess water and supplying air to the roots of the plant.

Since planting is performed on the cultivation container 2, it can be performed on the ground, not on the roof. When planting in the cultivation container 2, as shown in FIG.
A drainage layer 6 is provided at the bottom of the plant, and a planting medium 7 is placed on the drainage layer 6.
To form

The medium 7 may be a light soil, a vegetation mat such as rock wool felt, a coconut fiber mat or a wood chip mat, or a vegetation soil obtained by packing a lightweight soil bag in a root-proof sheet bag made of nonwoven fabric or the like. It can be a pack,
In addition, various medium materials may be used.

For planting, seeds may be charged into the culture medium 7, or in the case of a vegetation mat or a vegetation soil pack, a sheet with seeds previously attached thereto, a seed sheet may be attached later, or It may be performed by various methods such as planting seedlings. If management is required at the early stage of planting, this management can be performed before the cultivation container 2 is installed on the roof, and cultivation management can be easily performed. As the plant, for example, various plants such as a ficcus, an herb, an ivy, a vine, and an evergreen plant such as a broom may be used.

After completing the planting in the container 2 as described above,
After the difficulty in planting technology has been resolved and the plant is in a state where it can grow healthy and healthy in the natural world, construction work for installing this cultivation container 2 on a folded roof is performed. In this installation work, it is only necessary to carry the cultivation container 2 after planting on the roof and install it on the roof, and it is not necessary to perform troublesome planting work on the roof.

The cultivation container 2 is installed on the roof,
What is necessary is just to set in the folding valley part 1a toward the flow direction of the folding plate 1. The container 2 is located in the folded valley 1a, and is therefore less susceptible to wind pressure.
With a simple structure that can only be set inside, it can be installed stably and with no problem in strength.

In this installation operation, the cultivation container 2 is configured such that the projections 4, 4 provided on the outer surfaces of the both side walls 2b, 2b are brought into contact with the inclined surfaces on both sides surrounding the inside of the folded valley 1a. Within the valley 1a, the fold 1 is automatically positioned at a predetermined appropriate position in the lateral direction orthogonal to the flow direction. Thereby, the work of setting the cultivation container 2 in the folded valley 1a is performed properly and efficiently.

It should be noted that, due to the inclination of the folded roof, or
The fixed hardware 8 is used to prevent the cultivation container 2 from moving or flying in the direction of the folded plate by a strong wind such as a typhoon.
It is preferable to fix the cultivation container 2 by using. If the fixed roof 8 is of a round goby type,
What is necessary is just to attach using a goby part, and if it is a bolt type, it is sufficient to attach using the bolt.

In this installation state, as described above, the cultivation container 2 has the projections 4, 4 provided on the outer surfaces of the both side walls 2b, 2b in contact with the inclined surfaces on both sides in the folded valley 1a. As a result, both side walls 2b, 2b of the container 2 and the folded valley 1
a space 5 for ventilation is formed between the inclined surfaces on both sides in the container a, and the projections 4 provided on the lower surface of the bottom wall 2a of the container 2 also contact the bottom surface surrounding the folded valley 1a. The space 5 for ventilation is also formed between the bottom wall 2a of the container 2 and the bottom in the folded valley 1a. These ventilation spaces 5 ensure the air permeability between the container 2 and the folded plate 1, and the folded plate 1
Corrosion is prevented. Of course, since the culture medium 7 is accommodated in the container 2 and does not come into contact with the roof folding plate 1, there is no problem of folding corrosion due to direct contact between the culture medium and the folding plate. In addition, when it rains, rainwater can flow through the ventilation space 5 in the valley 1a, and does not impair the rainwater drainage function of the folded roof.

Further, since the container 2 is supported by the both side walls 2b, 2b and the bottom wall 2a on both side slopes and the bottom surface surrounding the inside of the folded valley 1a via the projections 4,... Even if the container 2 itself does not have a large strength, no mechanical trouble is caused.

That is, as shown in FIG. 4, a PVC pipe is used as a raw material, the peripheral side wall thereof is cut to produce an arc-shaped container 2 having an open top, and drainage holes 10 are formed in the cut-out pieces 9 to be cut out. This is set in the container 2 to form the drainage layer 6. Then, the culture medium 7 is set on the drainage layer 6 in the container 2 and planting is performed. Then, the cultivation container 2 planted in this way is set in the valley 1a of the roof folding plate 1 as shown in FIG. Since the cultivation container 2 has an arc shape in cross section, the cultivation container 2 is in line contact with the slopes on both sides surrounding the folded valley 1a as shown in the drawing, and the space between the surface surrounding the folded valley 1a and the container 2 is formed. 5, the installation structure that does not corrode the folding plate 1 can be obtained, and the container 2 in the transverse direction orthogonal to the folding plate flow direction can be obtained simply by setting the container 2 in the folding plate valley 1a.
Positioning is achieved, and the installation work is easy.
