DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure for installing a solar energy utilization device on a roof, and more particularly to a solar energy utilization device such as a solar water heater or a solar cell on a sloped roof of a building. Without compromising the typical aesthetics
The present invention relates to a structure of a roof which can be installed at an angle higher than the roof surface and efficiently, and is particularly suitable for a medium-sized or large-sized building such as a school gym.

[0002]

2. Description of the Related Art When a solar energy utilization device represented by a hot water heater or a power generation device is installed in a building, most of the solar energy utilization device is installed on a roof surface. Installation is rare.

[0003] Therefore, as a stand for installing a solar energy utilization device at a higher angle than the roof surface on a part of a newly built or existing general sloped roof, one having a configuration described in Japanese Utility Model Application Laid-Open No. 63-87853. There is. This configuration of the gantry has an advantage that it can be installed at an angle where solar energy can be efficiently obtained, compared to a configuration in which the device is installed in parallel with the slope of the gentle slope. However, the configuration of the above publication has a drawback that the design properties are extremely low because the support members such as the angle members are exposed. In the first place, the building is designed to match the landscape including the surrounding environment, and the roof occupies about half the weight.
In recent years, among solar energy utilization devices, solar heat collectors and the like have been unitized, and the design as a single item has been considerably improved, but it can not be expected to harmonize with the building when installed on the roof That is the reality. Furthermore, in the configuration of the proposal, since the installation location is limited to the ridge, the amount of energy obtained by the ridge length of the target roof surface is also limited, so it is highly possible that the required energy amount of the installation target property cannot be satisfied. .

In the case of a newly-built property, it is possible to design the slope of the roof surface to be installed at an optimum angle according to the purpose. However, when the roof slope is calculated from the annual average optimum slope angle in Japan (Tokyo). , The gradient is about 6 degrees (approximately 31 degrees).
There is a problem that the frame construction cost increases compared to the roof of (degree).

[0005] The performance of a solar energy utilization device depends on the amount of solar radiation. However, since the amount of solar radiation is determined by the positional relationship between the sun and the earth, it differs depending on the place where it is installed and the season. For example, the optimum tilt angle of the equipment in Tokyo is: 32.7 degrees for the whole year (January to December): 57.0 degrees for winter (December to February): 20.3 degrees for spring (March to May): 7.2 degrees for summer (June to August): 7.2 Degree Autumn (September to November): 41.4 degrees. Regarding hot water heaters, the installation angle of the equipment tends to be set at a steeper angle (> 33 degrees) than the optimal tilt angle for the whole year due to the relationship between the season and the necessity (requirements in winter).
The slope of the slope of buildings in cold districts is generally set to a steep angle, so the roof slope is considered to be close to the optimal slope of 32.7 degrees for the equipment in Tokyo for the whole year, but energy demand in cold districts increases in winter. Therefore, if this is emphasized, the device will be installed at less than 60 degrees.

As described above, in the conventional apparatus, when the solar energy utilization device is installed on the roof surface at an optimum angle at which the performance is maximized, harmony with the building cannot be obtained. If priority is given to harmony with the solar cell, there is a problem in the installation structure that the solar energy utilization device cannot be mounted at an optimum angle.

[0007]

The problem to be solved is that the solar energy utilization device is installed on the roof surface regardless of whether it is a newly built roof or an existing roof, and the performance of the device is improved without impairing the design of the whole building by installing it. That is, it cannot be installed at the optimum angle that is maximized.

[0008]

In order to solve the above-mentioned problems, a solar energy utilization device is installed on a part of a sloped roof surface. , at a steep angle than the installation target roof surface Munakata
Rising to direction, and the vertical frame attachable solar energy utilization system, a water gradient to at least eaves direction, Ri Do and a possible transverse frame attaching roofing, vertical frame top and horizontal frame eaves
A device installation support member having a side end integrally framed is attached in a girder direction of a building, a solar energy utilization device is attached to the vertical frame, and a roof material is attached to the horizontal frame. The support member for installation, the solar energy utilization device, and the roof material and the roof surface are each covered with a drainer.

[0009] In the present invention, the roof surface is a new roof surface on which a base roof surface is formed on a skeleton and a new roof plate is mounted on the base roof surface. The surface is a roof surface having the base roof surface as an installation target portion.

In the present invention, the roof surface is a new roof surface on which a new roof plate is formed on a base body, and a new roof plate is mounted on the lower roof surface. The surface is a roof surface on which a support member for device installation can be attached and a required number of installation members subjected to a rain sewage treatment are provided as installation target sites when the new shingle is attached to the base roof surface. And

Further, in the present invention, the roof surface is an existing roof surface, and the roof surface to be installed with the solar energy utilization device is a mounting member on which a device installation support member can be mounted and which has been subjected to a rain closing process. Is a roof surface provided in a required number on the existing roof surface as an installation target portion.

Further, in the present invention, a part or all of the solar energy utilization device is a power generation device, and a side surface of the installation member is formed as a ventilation surface by a ventilation louver. I do.

In the present invention, the roof material attached to the horizontal frame is a solar cell panel.

Regarding the roof surface to be installed with the solar energy utilization device according to the present invention, whether it is new or existing, the type of roofing of the new roof and the existing roof is not particularly limited. However, the roof material attached to the horizontal frame is a water gradient (about 3 degrees)
Since the slope is extremely gentle, the roofing is suitable for a gentle slope such as a vertical roofing type or a panel type with waterproofing treatment such as packing and sealing. The material of the roofing material, in the case of metal, is a known metal plate such as painted steel plate, stainless steel, aluminum, etc., but in consideration of the walking of workers at the time of maintenance of the utilization device, as a configuration by a waterproof sheet method. Is also good.

When the roofing material is other than a panel, a wooden piece, a wool cement board, and a resin insulation board are laid on the horizontal frame as a base, and the roofing material is constructed. An auxiliary support member such as each pipe may be interposed.

It is preferable that a portion adjacent to the heat collecting unit and the solar cell panel constituting the solar energy utilization device is waterproofed by packing or sealing. The device installation support member is made of a steel material such as iron or stainless steel, an aluminum shape material, or the like, and is assembled by a known connection means such as bolt joining or welding. If the solar energy utilization device to be installed is long in the girder direction, the supporting members for installation of the device will have insufficient strength in terms of the mounting relationship between the base roof surface or the newly installed or existing roof surface. An attachment structure is provided on the support member side and the roof surface side so as not to cause the generation. When the roof surface is a new roof surface, the base roof surface is formed by arranging a base material such as a heat insulating material or a roof plate support member such as rafters on a skeleton such as a steel frame or a concrete structure. There are various types of mounting members depending on the roof type and whether the roof is new or existing. Note that this mounting member is not limited to the configuration illustrated in FIG. 10, and may have any configuration as long as it is a known configuration. Although the rain finishing process of the mounting member is the same as the preceding paragraph, the retrofitting is basically performed in combination with a watertight process such as packing or sealing. However, depending on the type of roofing, there is a case where special rain closing processing is not required, for example, when fitting fittings are attached to vertical roofing. The drainer is generally made of the same material as the roof material. Each draining member is composed of one member or a plurality of members such as a rain gutter and a valley plate, depending on the configuration of the roof surface and the base.

[0017]

[Function] Consists of a vertical frame on which the solar energy utilization device can be attached at a steeper angle than the installation target roof surface, and a horizontal frame that has a water gradient at least in the direction of the eaves and can be fitted with roofing material. A support member for installing the device is mounted in the direction of the girder of the building, a solar energy utilization device is mounted on the vertical frame, and a roofing material is mounted on the horizontal frame, respectively. And since the roof material and the roof surface are each covered with a drainer, the solar energy utilization device can be installed at an optimum angle even on a gentle sloped roof surface, and the solar energy utilization efficiency can be improved. Can be increased. In particular, the solar energy utilization device can be installed at a steep angle of up to 90 degrees, which is effective for relatively steep roof surfaces, and is suitable for areas where energy demand increases in winter. Since the installation base and the like are not exposed and the entire roof surface is provided with a plurality of stages of accents using one to a plurality of rows of solar energy utilization devices, it is possible to provide a roof that is extremely rich in design. In order to obtain a sense of unity as a roof between the equipment and other roof surfaces, it is necessary to consider the structure of the frame, but in this case, the structure above the frame can be constructed by the roof construction company So, new construction,
Irrespective of the renovation, it is possible to suppress an increase in design cost, frame cost, and management cost.

[0018] The roof surface is a new roof surface on which a base roof surface is formed on a frame and a new roof plate is mounted on the base roof surface. Since the roof surface has the roof surface as the installation target portion, the construction cost can be suppressed by using the solar energy utilization device also as the roof function of the newly-installed shingle.

The roof surface is a new roof surface on which a base roof surface is formed on a skeleton and a new roof plate is mounted on the base roof surface. When installing a new shingle on the roof surface,
Since the required number of installation members to which the support members for installation of the equipment can be attached and the installation members that have undergone rain treatment have been provided as installation target parts, the installation surface of the equipment on the new roof surface has been virtually waterproofed. Because it has a double-roofed roof structure,
Rain performance (safety) as a roof is improved. Also,
There is no need to perform special waterproofing for electrical wiring and the like.

The above-mentioned roof surface is an existing roof surface, and the installation target roof surface of the solar energy utilization device is provided with a mounting member to which a device installation support member can be attached and which has been subjected to a rain cut-off process. Since the required number of roof surfaces are provided on the existing roof surface, the installation surface of the same device on the existing roof surface has a double-roofed roof structure due to the waterproofing treatment. ) Is improved.
Also, it is not necessary to perform a special waterproofing process on electric wiring and the like.

A part or all of the solar energy utilization device is a power generation device, and is located on a side of the device installation support member.
Since the surface is formed as a ventilation surface by a ventilation louver, the space formed by the device and the lower roof surface can be ventilated, so the power generation efficiency of the solar cell due to the high temperature of the space Can be prevented from decreasing. In addition, if the ventilation fan is driven by the power of the solar cell provided at least in part, effective ventilation can be performed even if the length of the device in the digit direction is long.

Since the roof material attached to the horizontal frame is a solar cell panel, the horizontal frame has a gentle slope, so that the power generation efficiency in summer is high. Also, if the utilization device installed on the vertical frame is a solar water heater, the steep solar water heater and the gentle slope solar cell panel can exhibit the maximum efficiency in winter and summer respectively and complement each other . Further, when the utilization device installed in the vertical frame is a solar cell, it is possible to correct variations in the amount of power generation in summer and winter, and to stably obtain electric energy.

Even if there is, the solar energy utilization device can be installed at an optimum angle, and the utilization efficiency of the solar energy can be increased.
In particular, the solar energy utilization device can be installed at a steep angle of up to 90 degrees, which is effective for relatively steep roof surfaces, and is suitable for areas where energy demand increases in winter. Since the installation base and the like are not exposed and the entire roof surface is provided with a plurality of stages of accents using one to a plurality of rows of solar energy utilization devices, it is possible to provide a roof that is extremely rich in design. In order to obtain a sense of unity as a roof between the equipment and other roof surfaces, it is necessary to consider the structure of the frame, but in this case, the structure above the frame can be constructed by the roof construction company Therefore, regardless of new construction or renovation, it is possible to suppress increases in design costs, frame costs, and management costs.

According to claim 2, the roof surface is a new roof surface on which a base roof surface is formed on a skeleton and a new roof plate is mounted on the base roof surface. Since the surface is a roof surface having the base roof surface as an installation target portion, the construction cost can be suppressed by using the solar energy utilization device also as a roof function of a newly-installed roof plate.

According to claim 3, the roof surface is a new roof surface on which a base roof surface is formed on a skeleton and a new roof plate is mounted on the base roof surface. The surface is a roof surface on which a required number of mounting members on which a device installation supporting member can be attached and a rain-treated process is provided as a target installation site when the new shingle is attached to the base roof surface. The installation surface of the device on the roof surface has a double-roofed roof structure due to the waterproof treatment, so that the performance of the rain as a roof (safety) is improved. Also, it is not necessary to perform a special waterproofing process on electric wiring and the like.

According to claim 4, the roof surface is an existing roof surface, and the roof surface on which the solar energy utilization device is to be installed is a mounting member to which a device installation support member can be attached and a rain closing process has been performed. Since the required number of roof surfaces are provided on the existing roof surface as the installation target site, the installation surface of the same device on the existing roof surface has a double-roofed roof structure due to the waterproof treatment, so the roof Rain performance (safety) is improved. Also, it is not necessary to perform a special waterproofing process on electric wiring and the like.

According to a fifth aspect of the present invention, a part or all of the solar energy utilization device is a power generation device, and a side surface of the device installation supporting member is formed as a ventilation surface by a ventilation louver. And the space formed by the lower roof surface can be ventilated, so that it is possible to prevent a decrease in the power generation efficiency of the solar cell due to an increase in the temperature of the space. In addition, if the ventilation fan is driven by the power of the solar cell provided at least in part, effective ventilation can be performed even if the length of the device in the digit direction is long.

According to the sixth aspect, since the roofing material attached to the horizontal frame is a solar cell panel, the horizontal frame has a gentle slope, so that the power generation efficiency in summer is high. Also, if the utilization device installed on the vertical frame is a solar water heater, the steep solar water heater and the gentle slope solar cell panel can exhibit the maximum efficiency in winter and summer respectively and complement each other . Further, when the utilization device installed in the vertical frame is a solar cell, it is possible to correct variations in the amount of power generation in summer and winter, and to stably obtain electric energy. Along with that,
When the installation area of the utilization device exceeds the required power amount of the building, surplus power can be sold to a power company.
