Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sloped roof, such as a gable roof or a ridge roof.

[0002]

2. Description of the Related Art Japanese Patent Application Laid-Open No. 2000-166375 discloses a technique in which a plant cultivation facility is provided on a roof surface to enhance the heat insulating effect of a house, to beautify a cityscape, and to prevent environmental degradation. I have. By the way, in order to suppress damage during an earthquake, it is essential to reduce the weight of the roof, and it is difficult to store a large amount of water on the roof for plant cultivation. Therefore, when plants are grown on the south-facing slope of the roof that is exposed to the intense sunlight in summer, the plants may die due to lack of water. In addition, a technique of installing solar energy utilization equipment such as a solar panel incorporating a solar cell on a roof in order to effectively utilize solar energy is also well known. However, the efficiency is poor because the amount of light is small on the north-facing slope of the roof and sufficient sunlight cannot be captured.

[0003]

The present invention takes advantage of the characteristics of the south-facing slope and the north-facing slope to efficiently utilize the roof surface for plant cultivation, solar power generation, etc., and to provide a heat insulating property for houses. And to provide a roof that contributes to environmental improvement.

[0004]

In the roof of the present invention, solar energy utilization equipment is installed on a south-facing slope, and a plant cultivation device is installed on a north-facing slope. In the present invention, southward and northward not only mean true south and true north, but also include directions shifted to the east or the west, respectively. The solar energy utilization equipment is installed on the south-facing slope, so that solar energy can be used efficiently. By installing a plant cultivation device on the north-facing slope, it is possible to prevent plants from withering due to direct sunlight in summer.

[0005] The north-facing slope is stepped with a metal plate on which a weir plate along the horizontal direction is erected, and the outer surface of soil having a predetermined thickness is wrapped with a water-permeable sheet above the incline of the weir plate. A plant cultivation device composed of a vegetation sheet may be locked.
Prevents plant cultivation equipment from falling on the weir plate. The rainwater flowing down to the eaves accumulates on the upstream side in the gradient direction of the weir plate and is distributed uniformly in the horizontal direction.

[0006]

Embodiments of the present invention will be described below in detail with reference to the drawings. As shown in FIGS. 1 and 2,
The roof 1 is a gable roof. The solar energy utilization facility 3 is installed on the south-facing slope 2, and the plant cultivation device 5 is installed on the north-facing slope 4. Examples of the solar energy utilization equipment 3 include a passive solar system that uses solar energy for heating and cooling, and a solar power generation panel system that incorporates a solar cell. Such a solar energy utilization facility 3 is installed on the south-facing slope 2 of the roof 1 in the same manner as in the related art.

As shown in FIG. 3, the north-facing inclined surface 4 of the roof 1 is provided with a waterproof sheet 7 laid on a field board 6, and the surface thereof is stepped with a metal plate 8. Near the lower end of the metal plate 8 in the gradient direction, a weir plate 9 along the horizontal direction is erected at an angle of about 90 degrees, and a lower end 10 is formed by folding the lower end of the gradient direction to the back side. . The upper end of the metal plate 8 in the gradient direction is turned back to the front side, and the upper
1 is formed, and in order to enhance the waterproofness, the groove portion 12 is extended from the upper hand 11 to the upstream side in the gradient direction, and the tip thereof is turned back to the surface side to form the water return piece 13. Then, the groove 12 is nailed to the field board 6, or the upper seam 11 or the water return piece 13 is fixed to the field board 5 with a suspender, and the metal plate 8 is attached along the horizontal direction. The lower plate 10 is locked to the lower metal plate 11 at 11.

When the metal plate 8 is stepped in this manner, the weir plate 9 stands upright at right angles to the roof surface, and the rainwater 14 flowing down along the slope is received by the respective weir plates 9 and stays there, and stays in the horizontal direction. Will be evenly distributed. In addition, the connection structure of the metal plate 8 is not limited to the above as long as rainwater does not flow to the field board 6 through the joint. For example, a waterproof strip may be backed at the engagement portion between the lower and upper hairs, or a caulking material may be filled at the engagement portion.

The plant cultivation apparatus 5 is composed of a vegetation mat in which soil of a predetermined thickness mixed with plant seeds, fertilizers and the like is wrapped with a sheet of permeable fiber or the like. The width of the plant cultivation apparatus 5 in the gradient direction is substantially equal to the width of the metal plate 8 in the gradient direction. And the plant cultivation apparatus 5 is locked above the slope direction of the weir plate 9 of the metal plate 8 so as not to slip down to the eaves side, and fitted between the weir plates 9 of the vertically adjacent metal plates 8,
It is laid on the entire north-facing slope 4. In addition, the lower end of the plant cultivation device 5 locked above the weir plate 9 in the gradient direction is immersed in the rain water 14 received and retained by the weir plate 9, and the rain water 14 is sucked up to above the soil by the capillary phenomenon.

The plants to be planted in the plant cultivation apparatus 5 are resistant to temperature changes and drying, do not require frequent care, and do not generate a large amount of dead leaves and dead flowers, for example, turf, weeping lab Glass, ivy, etc. are suitable. If necessary, it is also possible to install a watering facility for watering the north-facing inclined surface 4. Furthermore, the shape of the roof may be any shape as long as it has a slope, and a roof with a ridge, a mansard roof, or the like may be used.

[0011]

According to the first aspect of the present invention, the solar energy is efficiently used by utilizing the characteristics of the south-facing slope and the north-facing slope of the roof, and plants are cultivated under favorable conditions. As a result, the heat insulation performance of the house can be improved, which contributes to environmental improvement such as absorption of CO ₂ and mitigation of the heat island phenomenon. Claim 2
According to the invention according to the present invention, it is possible to stably support the plant cultivation device so as not to slip down, to store the rainwater flowing down to the eaves at once for each weir plate, and to distribute the water uniformly in the horizontal direction. It becomes possible to supply to a plant cultivation device.
