Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a solar cell panel mounting structure for a building roof, and can be used for installing or adding solar cell panels to a roof of a house or a store.

[0002]

BACKGROUND ART In recent years, housing needs have been diversified, and a range of roof slopes and roof finishes has been widened. Regarding the roof shape, in addition to the conventional gabled roof, dormitory roofs and flat roofs are becoming more prominent, and complex shapes such as iris roofs and roof roofs can be seen. In addition, since the attic has come into widespread use, there are some that are equipped with a top light for daylighting, and some have a rooftop balcony with part of the attic open to the outside. At the top of this rooftop balcony, louvers, etc. made of steel aggregate that is assembled to extend from the roof surface may be formed in consideration of the appearance, etc. It has an effect.

On the other hand, in modern life, electric power is used for various operations such as lighting, heating, power, cooling and heating. Usually, electric power is supplied from public commercial power sources, and in rare cases hospitals and the like also used emergency private power generation. In recent years, the power generation efficiency of solar cells has improved,
As prices have fallen, private power generation using solar power has come to be adopted in buildings such as ordinary houses and offices.

Conventionally, a solar cell used for solar power generation has been provided as a panel having a predetermined standard size.
A certain number of panels are arranged when arranged on the roof to receive sunlight. These solar cell panels are arranged with both side edges supported by rail-shaped members laid parallel to the roof surface.

[0005]

However, when the solar cell panel is installed on the roof surface, it is necessary to lay the above-mentioned rail-shaped member or the like on the roof surface. In addition, when installing in a place that does not have a roof surface such as a rooftop balcony, for example, form a roof surface so as to cover the rooftop balcony and waterproof it, and then lay the rail-shaped member. You have to do it. As described above, there is a problem that the work of constructing the solar cell panel is complicated and time-consuming.

When a solar cell is installed on the roof by renovation, a rail-shaped member, a solar cell panel, etc. are installed on the upper surface of the roof, so that the exterior of the original roof is hidden or an accessory such as a louver is attached. There is a problem that the exterior before remodeling is wasted in installing the solar cell panel, such as when the solar cell is removed. In addition, when installing solar cells on the roof part due to design changes, there is no waste like these, but it is necessary to order new support members for solar cell panel placement, etc., which is troublesome and lacks speed. There is a problem.

An object of the present invention is to install a solar cell panel on a roof of a building quickly and easily, and
It is intended to provide a solar cell panel mounting structure for a building roof that can effectively utilize the exterior material of the roof regardless of the presence or absence of the solar cell panel.

[0008]

SUMMARY OF THE INVENTION The present invention is intended to achieve the above object by supporting a solar cell panel on a framed frame structure having an exterior. Specifically, referring to the drawings, the solar cell panel mounting structure for a building roof according to the present invention has a frame assembly structure 26, 61, 62 in which the shaft members 25 are combined.

When installing solar cells by remodeling, the frame structure 26, 61, 6 used as the exterior material of the roof.
Since 2 can also be used as a support frame for the solar cell panel 41, it is not necessary to replace the exterior material with the support frame, the exterior material of the roof is not wasted, and the solar cell panel 4 is not used.
Construction of 1 becomes easy. Even when a solar cell is installed due to a design change, it is not necessary to prepare a support member for the solar cell panel 41 again, and the frame assembly structure 26, 61, 62 is directly used.
Since the solar cell panel 41 can be used to support the solar cell panel 41, the work after the design change can be performed easily and quickly, and the degree of freedom of the design change can be increased.

As described above, the frame assembly structures 26, 61, 62
Since it can be used with high flexibility in two ways as an exterior material and a support base for the solar cell panel 41, it is possible to easily install the solar cell panel 41 on the roof of the building at low cost and to effectively use the roof exterior material. Can be used for.

Further, the frame assembly structures 26, 61 and 62 can support the solar cell panel 41 and can also serve as an exterior material when the solar cell panel 41 is absent. The aesthetics of the roof is maintained regardless. That is, the frame assembly structures 26, 61, 6
Even when the solar cell panel 41 is locally installed only in a part of 2, since the shaft member 25 is provided with the exterior, the appearance of the portion where the solar cell panel 41 is not arranged is not deteriorated. Therefore, if the number of solar cell panels 41 that can be installed in the frame structure 26, 61, 62 is less than or equal to the maximum number, the number of solar cell panels 41 installed can be selected in a wide range.

As described above, the frame assembly structures 26, 61, 62
Can be used regardless of the number of solar cell panels 41,
Even when the solar cell panel 41 is removed, it is not necessary to apply waterproofing or exterior processing to the removed portion. That is,
It is possible to easily increase or decrease the number of installed solar cell panels 41 simply by arranging or removing the solar cell panels 41. In addition, conventionally, the addition and removal of the solar cell panel 41 required complicated work such as installation and removal of the support member each time in order to maintain the appearance of the roof. , 61, and 62, the good appearance is maintained even if the solar cell panels 41 are not arranged, so that the complexity is further reduced and the number of solar cell panels 41 to be installed can be easily adjusted. Become. With these, the above object is achieved.

The shaft assembly structures 26, 61, 62 are provided with at least a pair of parallel vertical shaft members 240 extending in the vertical direction as the supporting shaft members 24 for supporting the solar cell panel 41. The material 240 is the solar cell panel 4
It is desirable to be able to support both lateral edges of 1.

As a result, the above-mentioned frame assembly structures 26 and 6 are provided.

BEST MODE FOR CARRYING OUT THE INVENTION An embodiment of the present invention will be described below with reference to the drawings. In FIGS. 1 and 2, a building 1 is a building used as a house in which a roof portion 2 is installed on a building frame 3. The building skeleton 3 is configured by combining a plurality of box-shaped rectangular parallelepiped building units 30.

The roof portion 2 is a gable roof constructed by combining the roof units 20. The roof unit 20 constitutes a side unit 210 and an eaves side unit 211 having a sloping roof 210A, and a walkable rooftop 220A. It is composed of a unit 220 and a penthouse unit 221. A penthouse unit 221 is arranged in the center of the roof portion 2, and the penthouse unit 2
Middle units 220 are installed on both sides in the ridge direction of 21. Eave side units 211 are arranged on both sides of the penthouse unit 221 in the eaves direction, and side units 210 are installed on both sides of the middle unit 220 in the eaves direction.

The penthouse unit 221 has a glass roof portion 222 formed by a glass sash substantially continuous with the pitched roof 210A, and a door 2 for entering and exiting the roof 220A.
And a wall portion 223 including 24. The floor of the side unit 210 and the roof 220A of the middle unit 220
The roof top surface 225 formed in (1) does not have a roof surface, and thus is waterproofed.

Above the roof top surface 225, a frame assembly structure 26 including the ridge shaft member 23 and a plurality of vertical shaft members 240 is provided. The main shaft member 23 and the vertical shaft member 240 are long steel members, and are coated by surface coating to ensure waterproofness and good appearance. The ridge shaft member 23 has a substantially rectangular cross section and is provided so as to extend horizontally from the ridge of the penthouse 221. As shown in FIG. 3, the vertical axis member 240 includes a convex portion 242 and a flat surface portion 241 formed on both sides of the convex portion 242.
It has a substantially inverted T-shaped cross section including and, and is provided so as to extend from the ridge shaft member 23 so as to be substantially continuous from the pitched roof 210A.

As described above, the plurality of longitudinal members 240 are arranged in parallel and the arrangement pitch l of the solar cell panel 41 is arranged.
Are arranged at a predetermined interval corresponding to. That is, a position (l = m) where the center distance m between adjacent vertical axis members 240 is equal to the arrangement pitch 1 of the solar cell panels 41.
The vertical frame member 240 is fixed to the shaft assembly structure 26. In addition, of the vertical axis members 240, the solar cell panel 41
The length P in the solar cell array arrangement direction of the flat surface portion 241 arranged at a position where the solar cell panel 241 can be supported is an integral multiple of the vertical dimension p of the solar cell panel 41 (P = n × p, n is a natural number). There is.

The ridge shaft member 23 and the vertical shaft member 240 form a frame structure 26 having a substantially gable roof shape. Since only the frame assembly structure 26 is provided above the side unit 210 and the middle unit 220, both sides of the penthouse 221 are open to the outside. Therefore, the roof portion 2 has a shape in which both ends of the gable roof are cut out, but the grate roof shape is adjusted by the frame structure 26.

In this embodiment as described above, when the solar power generation device 40 is installed by remodeling or the like, the solar cell panels 41 having a standardized size are arranged. The solar cell panel 41 has a predetermined number of solar cells housed inside a flat waterproof case. In arranging the solar cell panels 41, the pair of opposing flat surface portions 241 of the pair of adjacent vertical axis members 240 support both lateral edges of the solar cell panel 41.

When the vertical end portions of the solar cell panel 41 are abutted against each other and sequentially arranged along the vertical axis member 240, the length P of the vertical axis member 240 is equal to the vertical dimension p of the solar cell panel 41. Since it is an integral multiple, a predetermined number of solar cell panels can be accommodated without forming a non-arrangeable gap in the end of the vertical axis member 240. By arranging the solar cell panels 41 in this way, an inclined light receiving surface 42 is formed, and the back surfaces of the light receiving surfaces 42 are arranged so as to face each other with the ridge shaft member 23 interposed therebetween. Become.

According to this embodiment as described above, the following effects can be obtained. That is, since the framed frame structure 26 with the exterior is installed on the roof part 2, the framed frame structure 26
The appearance of the roof can be maintained and waterproofness can be ensured even if no other exterior is applied to the part where is installed.

When the solar power generation device 40 is installed, the vertical axis member 240 has the flat portion 241 capable of supporting the lateral side edges of the solar cell panel 41 and the arrangement pitch l of the solar cell panel 41. The solar cell panel 41 is arranged along the pair of longitudinal members 240.
The solar cell panel 41 can be installed quickly and easily, and the shaft member 25 has an exterior.
Since the waterproof treatment is applied to the solar cells, the solar cell panels 41 can be immediately arranged without performing the waterproof treatment, which simplifies the construction and reduces the installation cost. In this way, the solar cell panel 4 can be used without wasting the frame structure 26 used as the exterior material of the roof 2.
The construction of 1 can be easily performed.

Since the vertical members 240 extend in the direction of the slope of the slope roof 210A and are arranged in a plurality, they can be used as a substitute for an existing support member and the existing solar cell panel 41 can be arranged as they are.

Furthermore, since the length P of the vertical axis member 240 is an integral multiple of the vertical dimension p of the solar cell panel 41, there is a surplus portion where the solar cell panels 41 cannot be arranged at the end of the vertical axis member 240. It is possible to avoid the occurrence of steps and gaps, ensure the appearance of the roof, and eliminate the need for adjusting members for eliminating steps and gaps, thereby reducing installation costs and simplifying construction work.

The vertical axis member 240 is inclined along the slope of the roof part 2, and the inclined light receiving surface 42 is formed by the arrangement of the solar cell panels 41, so that a relatively large light receiving area is secured and power generation is performed. The efficiency can be improved. The frame structure 26 is
Since the vertical axis member 240 is assembled in a mountain shape via the ridge shaft member 23 to have a so-called gable roof shape, it can be easily installed above the roof top surface 225 having no inclined roof surface.

The present invention is not limited to the above-described embodiment, but includes other configurations and the like that can achieve the object of the present invention, and the following modifications and the like are also included in the present invention. That is, in the above embodiment, the shaft member 2 made of steel is used.
Although No. 5 is used, it may be formed of synthetic resin or other inorganic material. The exterior of the shaft 25 is
Any material can be used as long as it can adjust the appearance and impart waterproofness, and the application is not limited to surface coating, and may be performed by attaching or attaching a surface material. When the shaft material is formed of synthetic resin or the like and the appearance and waterproofness are originally good, it is not necessary to dare to paint. In short, it is sufficient that the shaft member has at least a good appearance and waterproofness.

In the above embodiment, the solar cell panel 41 is used.
The shape of the vertical axis member 240 that is the support shaft member 24 that supports the
Although it was a long material with an inverted T-shaped cross section, a long material with a substantially C-shaped, U-shaped, H-shaped, I-shaped cross-section, etc. can be used as the supporting shaft material, and it is a lateral part that is the supported portion of the solar cell panel. Alternatively, it may be provided with a supporting portion corresponding to the shape of the side edge in the vertical direction or the bottom surface.

In the above-described embodiment, the length P of the vertical axis member 240 is an integral multiple of the vertical dimension p of the solar cell panel 41, but when the solar cell panels are arranged in the horizontal direction, the length P is set in the horizontal direction. The length of the extending supporting shaft member 24 may be an integral multiple of the lateral dimension of the solar cell panel. In short, it suffices that the supporting shaft member extending in the arrangement direction of the solar cell panels has a length that does not cause a portion where the solar cell panels cannot be arranged.
Even if a gap or a step is formed, the appearance will not be impaired if the adjusting member is installed, but it takes time and cost. Therefore, it is preferable that the length P of the supporting shaft member corresponds to the dimension p of the solar cell panel.

In the above-described embodiment, the vertical members 240 are arranged in the vertical direction along the slope direction of the slope roof 210A, but they may be arranged in the horizontal (ridge) direction or the oblique direction. In short, when forming the solar cell panel supporting portion, the direction is arbitrary as long as the supporting shaft members are fixed at intervals according to the arrangement pitch. The light receiving surface formed by installing the solar cell panel on the support shaft member may be provided horizontally or vertically. However, if an inclined light receiving surface is obtained, the power generation efficiency is increased, which is preferable.

Then, the frame assembly structure 26 of the above-mentioned embodiment
Is composed of only the ridge shaft member 23 and the vertical shaft member 240, but in addition to these, it may be structured to include a shaft member for exterior use and a support shaft member 24 for supporting the solar cell panel due to another shape. Good. That is, as long as a portion capable of supporting at least one solar cell panel is formed in the frame assembly structure, the shape and arrangement of the shaft members in the other portions are arbitrary.

In the above embodiment, a plurality of longitudinal members 240 are provided.
Are arranged at intervals according to the arrangement pitch 1 of the solar cell panels 41 and assembled in a gable roof shape to form the frame structure 26.
However, the shape of the framed frame structure is not limited to the shape of the roof such as the gable roof shape or the hipped roof shape, and may be a flat plate shape or a prismatic shape, and is arbitrary. In short, the shape of the frame structure is arbitrary as long as at least a pair of shaft members of the frame structure has a shape capable of supporting the solar cell panel and is fixed corresponding to the arrangement pitch.

In the above embodiment, as many solar cell panels 41 as possible are installed along the vertical axis member 240.
Several solar cell panels may be locally installed only in a part of the frame structure, and the number of solar cell panels to be installed is arbitrary as long as it is equal to or less than the maximum installable number. At this time, since the shaft member is provided with the exterior, the appearance of the portion where the solar cell panels are not arranged is not deteriorated.

The solar cell panel is not limited to a flat plate type, and for example, an engaging structure that can be fixed by fitting is formed on the side surface of the solar cell panel which is adjacent to the solar cell panel when the solar cell panels are arranged. The specific size, shape, etc. of the solar cell panel may be appropriately selected for implementation. However, the frame structure must be formed according to the selected solar cell panel.

In the above-described embodiment, the mountain-shaped frame structure 26 is applied to the roof top 225 of the gabled roof, but such a frame structure is applied to the flat roof 60. Good. That is, as shown in FIG. 4, when the mountain-shaped frame structure 61 is installed on the roof top surface 601 of the flat roof 60, substantially the same effect as that of the above-described embodiment is obtained, and the horizontal roof surface 601 is inclined. The light receiving surface 42 described above can be easily formed, and at the same time, an appearance like a triangular slope roof can be obtained.

Further, as shown in FIG. 5, when a building 6 having a flat roof 60 is provided with a courtyard or the like in the center so that the roof is open to the roof, the roof portion 602 of the roof is parallel to the roof 601. The frame assembly structure 62 may be installed. The installation position of the frame structure 26 is not limited to the roof part of the uppermost floor, and may be the roof part of any floor. In short, the installation place is arbitrary as long as it is the part where the roof is formed in the building.

In the above-mentioned embodiment, the building 1 is formed by combining the building unit 30 and the roof unit 20, but other prefabricated construction methods such as a panel construction method or a conventional construction method may be used. It may be a building.

[0050]

As described above, according to the present invention,
By installing a framed frame structure that has an exterior and can support solar cells on the roof part, this framed frame structure can be freely used in two ways, as an exterior material and a solar cell panel support frame. The solar panel can be easily installed and removed at low cost on the roof of the building, and the exterior material of the roof can be effectively used.

That is, if the frame structure is installed on the roof, it can be used as an exterior material because the shaft material has an exterior, and the appearance of the roof is maintained. When installing a solar cell panel, the frame structure has a part that can support the solar cell panel, so simply by arranging the solar cell panels without waterproof treatment, the solar cell panel can be quickly and easily installed. Can be arranged, and the installation cost can be reduced.

Further, since the aesthetic appearance of the roof is maintained regardless of the presence or absence of the solar cell panel in the frame structure, the appearance is impaired even if the solar cell panel is locally installed only in a part of the frame structure. There is no such thing. Therefore, if the number of solar cell panels that can be installed in the frame structure is less than or equal to the maximum number, the number of solar cell panels installed can be selected in a wide range. Since the solar cell panel can be easily removed, the number of installed solar cell panels can be freely increased or decreased.

Further, by forming at least a pair of parallel vertical shaft members extending in the vertical direction as shaft members for supporting both lateral edges of the solar cell panel in the frame assembly, as an alternative to existing support members. It can be used and existing solar panels can be arranged as is.

Further, if the length of the shaft member supporting the solar cell panel in the solar cell panel arrangement direction is an integral multiple of the size of the solar cell panel, the aesthetic appearance of the roof can be secured, and the steps and gaps can be secured. Since adjustment members for elimination are not required, installation cost can be reduced and construction work can be simplified.

By arranging the light receiving surface formed by the solar cell panel in an inclined manner on the frame structure, a large light receiving area can be secured and power generation efficiency can be improved. At this time, the two opposing surfaces of the frame assembly structure are assembled in an inclined mountain shape, and the outsides of the two surfaces are light-receiving surfaces, whereby a frame assembly structure having a so-called gable roof shape is obtained. The solar cell panels can be arranged in a slanted manner simply by installing the solar cell panels on a roof portion such as a rooftop balcony that does not have a slanted roof surface, and the solar cell panels can be easily installed at efficient positions.
