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 water heater, a solar battery, etc., on a sloped roof of a building whose roof surface faces east-west. The present invention relates to a roof structure in which a solar energy utilization device can be installed efficiently, without exerting a detrimental effect on the overall aesthetics of the building, in which the heat energy utilization capability is efficiently exhibited, and particularly in a north-south direction. It is suitable for small and medium-sized buildings such as gabled general houses with a wife surface.

[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. In the case of a gabled roof whose north and south sides have a gable side, the installation of the gantry becomes unstable and the design is extremely low.

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 case of a building having a wife surface in the north-south direction, it is possible to obtain harmony with the building by installing the solar energy utilization device on the roof surface facing south where the performance is maximized. On the contrary, if the harmony with the building is prioritized, there is a problem in the installation structure in which the solar energy utilization device cannot be installed in the south direction.

[0007]

The problem to be solved is that when the solar energy utilization device is installed on the roof surface of a building having a wife surface in the north-south direction, the roof surface faces in the east-west direction. Therefore, there is no choice but to give priority to either the direction that maximizes the performance of the solar energy utilization device or the harmony with the building, and it is not possible to obtain a satisfactory installation structure for both. .

[0008]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, a solar energy utilization device is installed on a part of a sloped roof having a wife surface in a north-south direction. A substantially dormer-shaped support member is attached to the installation target roof surface, and a solar energy utilization device is provided on the south side of the support member facing the sun, and a roof is provided on the north side opposite to the solar energy utilization device. A material is attached, and the support member, the solar energy utilization device, and the space between the roof material and the roof surface are each covered with a draining member.

According to the present invention, there is provided a structure for installing a solar energy utilization device on a roof in which a solar energy utilization device is installed on a part of a sloped roof having a wife surface in a north-south direction. The solar energy utilization unit and the roofing material on the north side are attached to the substantially dormer-like support members, respectively, and a substantially dome-shaped solar energy utilization unit is constructed in advance, and the solar energy utilization device faces south toward the sun. The solar energy utilization device unit of the solar energy utilization device unit and the roof material and the roof surface are each covered with a draining member.

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 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 base roof surface is formed on a skeleton and a new roof plate is mounted on the base roof surface. A surface is a roof surface provided with a required number of mounting members to which the support member or the solar energy utilization unit can be mounted and a rain-finished process has been performed as a target installation site when the new shingle is mounted on the base roof surface. There is a feature.

Further, in the present invention, the roof surface is an existing roof surface, and the roof surface to which the solar energy utilization device is to be installed is provided with an attachment member to which the support member can be attached and which has been subjected to a rain closing process. It is characterized in that a required number of roof surfaces are provided on an existing roof plate as the target site.

[0013] In the present invention, the surface of the support member or the solar energy utilization unit opposite to the surface on which the solar energy utilization device is installed is made of a ventilable roof material such as a louver. It is characterized by.

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. In the case where the solar energy utilization device is rectangular, a portion that is a gap with respect to the support member is constructed with the same roof material as that on the opposite side.
In the case of metal, a known metal plate such as a coated steel plate, stainless steel, or aluminum is representative of the material of the roofing material. If the roofing material is not a roof panel or a ventilation louver, as a base material, lay a piece of wood, wood wool cement board, resin insulation board on the horizontal frame and construct the roofing material, but if necessary,
An auxiliary support member such as a metal rafter or each pipe may be interposed.

It is preferable that a portion adjacent to the heat collecting and hot water unit and the solar cell panel constituting the solar energy utilization device is waterproofed by packing or sealing. The substantially dormer-shaped support member is made of a steel material such as iron or stainless steel, an aluminum mold material, or the like, and is assembled by known connection means such as bolt joining or welding. 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 type of roof and whether the roof is new or existing. Note that this mounting member is not limited to the configuration illustrated in FIG. 15, and may have any known configuration. The rain finishing process of the mounting member is the same as described above, but 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. The dormer-shaped support member or the rear surface of the solar energy utilization device unit is appropriately closed with a cosmetic material, but may be formed of a ventilable roof material such as a louver.

[0017]

[Function] A dormer-shaped support member is attached to the roof surface to be installed with a sloped roof having a north-south wife surface, and a solar energy utilization device is used on the south side of the support member facing the sun. Roofing materials are installed on the north side opposite to the device, so even if the building has no roof surface on the south side facing the sun, a solar energy utilization device is installed in the south direction where the performance is maximized. I can do it. Since the supporting member, the solar energy utilization device, and the roof material and the roof surface are each covered with a draining member, the supporting member and the like are not exposed. Is an accent, so the roof design is extremely rich in design. In order to obtain a sense of unity as a roof between the solar energy utilization device and other roof surfaces, it is necessary to consider the structure of the frame, but in this case, the structure above the frame is constructed by the roof contractor. Therefore, it is possible to suppress increases in design costs, frame costs, and management costs irrespective of new construction or renovation.

Since the solar energy utilization device, the roof material and the support member are unitized in advance, the substantially dormer-shaped solar energy utilization device unit can be attached and constructed as one unit.

Since the roof surface to be installed with the solar energy utilization device is a roof surface having the base roof surface formed on the skeleton as an installation target portion, the solar energy utilization device and the roof material in the substantially dormer-shaped support member are: It will also serve as the roof function of the newly installed shingle on the general surface.

The roof surface on which the solar energy utilization device is installed is a roof surface provided with a required number of mounting members on a newly installed shingle to be newly installed on the base roof surface, so that the installation surface of the device is newly installed. The roof plate, the solar energy utilization device and the roof material in the substantially dormer-like support member, and the roof material effectively form a double-roofed roof structure, and the rain-closing performance as the roof is improved.

The roof surface to be installed with the solar energy utilization device is a roof surface provided with a required number of mounting members on the existing roof surface as an installation target site. In effect, the roof structure has a double-roof structure using the solar energy utilization device and the roof material in the support member, and the performance of the rain as a roof is improved.

Since the surface opposite to the surface on which the solar energy utilization device is installed in the support member or the solar energy utilization device unit is formed of a ventilable roofing material such as a louver, the device can be connected to the solar energy utilization device through this ventilation opening. The space formed by the lower roof surface can be ventilated.
