Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a supporting member for supporting a plurality of solar light utilization means, which are installed on a roof of a building, for example, a plurality of solar power utilization means for generating power or collecting heat by utilizing solar energy. Relates to a solar array.

[0002]

2. Description of the Related Art Conventionally, for example, as shown in FIG. 8, a solar cell module M for converting solar energy into electricity is arranged on a roof K of a house S in order to reduce the electric load of a home. There are known solar cell arrays.

In the case of such a solar cell array, in order to install the solar cell module on the roof surface, support members such as vertical rails and horizontal rails are arranged on the roof surface, and the solar cell module is mounted on the horizontal rail or vertical rail. The method of mounting is taken. For example, as disclosed in Japanese Patent No. 3084003, a plurality of vertical rails installed on the roof surface in parallel with each other along the direction of inclination, and a plurality of vertical rails suspended in parallel with each other on the vertical rails. A grid is formed by a plurality of horizontal rails installed in the solar cell module, and the solar cell modules are arranged on the grid. In addition, these support members are usually processed to have different cross-sectional shapes and parts for the purpose, respectively, and are formed by extrusion molding of a metal such as aluminum as a material used for these. In general, a plate material such as an iron material is bent into a substantially C shape.

Next, a method of installing a solar cell array using a supporting member obtained by bending a plate material such as an iron material into a substantially C shape will be described as an example.

As shown in FIG. 7, a solar cell array MA
Is a vertical rail 4 installed along the direction of inclination of the roof, a rail fixing metal fitting 8f for fixing the vertical rail 4 to the roof, and a horizontal rail 2 installed on the vertical rail 4 substantially parallel to the roof ridge. A plurality of solar cell modules M are arranged on the horizontal rail 2.

Further, in order to support the vertical crosspiece 4, the horizontal crosspiece 2, the solar cell module M, etc., the lower plate of the crosspiece fixing metal fitting 8f is fixed to a strong roof support member called rafter with nails or screws. At this time, a roof plate that forms a roof on the rafter and a tile material may be arranged on this.

A vertical rail fixing screw for fixing the vertical rail 4 is welded to the lower plate. Further, it is general that an upper plate is provided on the vertical rail fixing screw in order to better receive the vertical rail 4 so that an error in the height of receiving the vertical rail 4 due to distortion of the roof itself can be corrected. is there.

The vertical rail 4 is fixed to a rail fixing metal fitting 8f. The rail fixing metal fitting 8f is arranged in accordance with a position where a rafter is placed, and moreover, such as a field board or roof tiles laid on the roof. The nails are not necessarily arranged at regular intervals because it is desirable to arrange them so as to avoid locations that are not suitable for hitting nails. Further, for the same reason, the mutual intervals in the vertical rails 4 are also equal to the intervals between the rafters and the like which form the roof, and are not related to the size of the solar cell.

On the other hand, the horizontal rail 2 is fixed to the horizontal rail 2 by a rail fixing metal fitting 6c with a screw or the like, and the solar cell module M is sequentially fixed on the horizontal rail 2 to form a solar cell array MA. It

However, the solar battery module M often has a substantially rectangular shape due to the power generation voltage, the arrangement of the solar battery cells, the shape of the mounting frame, etc., but when installed on the roof of a house, as shown in FIG. In addition, rather than arranging the solar cell modules M in a vertically long shape, it is possible to increase the number of installed solar cell modules by using a solar cell array in which the solar cell modules M are arranged in a horizontally long shape, and vice versa. May be able to increase the number of installation.

Therefore, it is desirable that the solar cell array can support the solar cell module M vertically and horizontally. However, the length of the crosspiece that supports the solar cell module M is the long side 1b of the solar cell module M. Of the solar cell module M on the roof surface because the mounting holes and the mounting holes on the vertical rails 4 and the horizontal rails 2 are different from each other. In order to deal with the case of arranging horizontally and vertically, there are two types of vertical crosspieces (a crosspiece that is an integral multiple of the long side length of the solar cell module M, and a substantially integer of the same short side length). Double cross), and two types of horizontal cross (a cross that is an integral multiple of the long side length of the solar cell module M,
And a total of four types of crosspieces (a length that is an integral multiple of the short side length) must be designed and managed, and there has been a problem that the work of selecting and managing the crosspieces necessary for the site becomes complicated. . Also,
When it is attempted to change the solar cell module from the horizontally long layout to the vertically long layout in order to add more solar cell modules later, it is necessary to newly replace both the vertical rail and the horizontal rail.

Therefore, the present invention solves the above-mentioned problems of the prior art, and easily copes with the installation work of solar light utilization means such as a solar cell module on the roof and the change of support members such as crosspieces due to expansion. It is an object of the present invention to provide an excellent solar array that can be used.

[0013]

In order to achieve the above object, the solar array of the present invention includes a first elongated array on a roof.
A plurality of the solar light utilization means are fixed to a pedestal in which a plurality of support members are arranged substantially parallel to each other and a long second support member is attached to these first support members in a state of being substantially orthogonal to each other. Each of the first and second support members includes a common solar light utilization means installation surface on which the solar light utilization means can be fixed, and a common support member installation surface on which another support member can be mounted and fixed. It is characterized by being The first support member and the second support member preferably have the same structure except for the entire length.

Further, each of the first support member and the second support member is provided with a common through hole which can be fixed to a roof support member constituting the roof.

Specifically, for example, vertical rails installed on the roof surface in parallel with each other along the inclination direction thereof, and a plurality of horizontal rails installed on the plurality of vertical rails in parallel with each other. With, the fixing of the solar cell module, especially the solar cell module, to the horizontal rail can be performed on either the long side or the short side of the solar cell module, while the vertical rail is on the horizontal rail.
By making the horizontal rail a common structure that can be used for the vertical rail,
Even when the installation direction of the solar cell module is changed, the support member can be made of the same component.

When the long side of the flat rectangular solar cell module is fixed to, for example, a horizontal crosspiece (hereinafter referred to as crosspiece A) which is the first support member, that is, the short side of the solar cell module along the inclination direction on the roof surface. When installing so that the sides are located, vertical bars (hereinafter referred to as bars B) that are second support members installed on the roof surface in parallel with each other along the inclination direction thereof.
After installing the plurality of crosspieces A which are installed so as to be laid on the plurality of crosspieces B in parallel to each other, the long side of the solar cell module is fixed to the crosspiece A. At this time, the crosspiece A for fixing the long side of the solar cell module has a length of approximately an integral multiple (including the same size) of the long side of the solar cell module, and the crosspiece B has an approximate length of the short side of the solar cell module. It is an integral multiple (including equal magnification).

On the other hand, when the long sides of the solar cell module are installed along the inclination direction of the roof surface, first, the long sides of the solar cell module are arranged on the roof surface in parallel to each other along the inclination direction, and are substantially integral multiples of the long sides. A crosspiece A having a length (including the same size) is installed, and a crosspiece B having a length of approximately an integral multiple (including the same size) of the short side of the solar cell module is parallel to the crosspiece A. The solar cell module is installed so that the short side of the solar cell module is fixed to the crosspiece B.

Fig. 4 shows how the rail fixing brackets are fixed to the roof.

As shown in FIG. 1, the solar cell array MA
Is a plurality of arranged solar cell modules M, a bar A which is a long first supporting member for fixing the solar cell modules M, a bar B which is a long second supporting member for fixing the bar A, and a bar. A pedestal mainly composed of a crosspiece fixing metal fitting 8f for fixing B to the roof of the house. In addition, a plurality of solar cell modules M are fixed.

Here, the solar cell module M is composed of a substrate having a light-receiving surface side made of glass or resin having a light-transmitting property, and a power generation portion covered with the substrate is made of silicon or a compound semiconductor. A plurality of elements (cells) are connected in series and / or in parallel, and the gap between the cells and the back surface side are protected by a member such as a moisture-resistant resin. Further, in this embodiment, the solar cell module M has a rectangular planar shape, and a frame member is attached to the peripheral portion thereof.
The planar shape of the solar cell module M may be other shapes, and the frame member may not be provided in the peripheral portion thereof.

Further, the crosspiece A and the crosspiece B are a common solar light utilization means installation surface described later on which the solar cell module M can be fixed, and a common support member described below on which other support members can be mounted and fixed. A common through hole that can be fixed to a roof support member (for example, a rafter) that constitutes the roof is provided on each of the crosspieces A and B. As shown in FIG. 2, the crosspiece A and the crosspiece B are formed by bending a plate material such as an iron material into a substantially C shape, a pipe having a substantially square cross section, or an extrusion molding of aluminum or the like. The rail fixing metal fitting 8g is provided with a rail fixing elongated hole 7a (common through hole) on the surface (support member installation surface 3a) through which the vertical rail fixing screw 9g penetrates. Further, the other surfaces 3b and 3c are surfaces on which the solar light utilization means is installed.

As shown in FIGS. 3 and 4, the crosspiece fixing metal fitting 8f is provided.
When securing the roof to the roof, it is desirable to hammer nails or screws to the roof support material called rafters under the base plate or roof tile material to secure the fixing strength, but it is not necessary to strike at fixed intervals. Is not always obtained. Due to the existence of the crosspiece fixing long hole 7a having a long hole shape along the longitudinal direction of the crosspiece, even if the driving position is deviated, it is possible to appropriately cope with the deviation. In addition to such an elongated hole, a large number of holes through which the vertical rail fixing screw 9g penetrates may be provided to cope with the above deviation. Further, on the surface where the long hole is formed, a crosspiece connecting screw hole 7b for fixing the horizontal crosspiece to the vertical crosspiece is provided.

On the other hand, the sun for fixing the solar cell module M is provided on one or two surfaces (sunlight utilization means installation surface) other than the surface through which the vertical rail fixing screws 9g of the rails A and B are penetrated. A battery module fixing screw hole 7d is provided.

With the above-described structure, the vertical bar installed along the slope of the roof surface has a vertical bar A having a length that is approximately an integral multiple of the long side 1b of the solar cell module M having a planar rectangular shape. , Or a crosspiece B having a length that is approximately an integral multiple of the short side 1a of the solar cell module M can be used. Similarly, for a crosspiece installed in parallel along the roof ridge, Either of the bars A or B can be used. In this way, the solar cell module M can be either a horizontally elongated solar cell array or a vertically elongated solar cell array, depending on whether the crosspiece A or the crosspiece B is given the role of a vertical crosspiece or a horizontal crosspiece. It is possible to provide a solar array that is highly versatile. In this example, the difference between the crosspiece A and the crosspiece B is mainly only in the total length.

Next, in order to fix the bar B, which is a vertical bar, on the roof, as shown in FIG. 4, the lower plate 9c of the bar fixing metal fitting 8f has a nail 9d at a strong portion called a rafter 9a of the roof. Or fix it with screws. At this time, the rafter 9a
A roof plate 9e for forming a roof thereon and a tile material 9 on the roof plate
It may be a state in which f is arranged. A vertical rail fixing screw 9g for fixing the vertical rail 4 is welded to the lower plate 9c. However, in order to better receive the vertical rail 4 on the vertical rail fixing screw 9g, the upper plate 9b is provided as shown in the figure. May be provided so that the error in the height for receiving the vertical rail 4 due to the distortion of the roof itself can be corrected.

The vertical bar fixing screw 9g of the vertical bar fixing bracket 8f is connected to the vertical bar B
Through the long holes 7a for fixing the crosspieces in order, and after that, after that,
The crosspiece A is arranged on the crosspiece B in a shape orthogonal to the crosspiece B. At this time, the crosspiece A is arranged in accordance with the interval between the short sides 1a of the solar cell module M. The crosspiece A is fixed to the crosspiece AB connecting screw hole 7b on the crosspiece B by using the crosspiece fitting 6c, the solar cell modules M are sequentially arranged on the crosspiece A, and the solar cell module fixing plate 8g is mounted on the crosspiece A. The battery module is fixed by screwing it into the screw hole 7d for fixing. At this time, the solar cell module M may be directly screwed to the crosspiece A without using the solar cell module fixing plate 8g. Also,
Only the outer frame of the solar cell module M may be supported by the crosspieces A, and the solar cell module M may be embedded in the gap between the crosspieces A to reduce the thickness of the solar cell array MA.

When the crosspiece A is used as the vertical crosspiece and the crosspiece B is used as the horizontal crosspiece, as shown in FIG. 5, the vertical crosspiece B is used as the horizontal crosspiece, and the horizontal crosspiece A is used as the vertical crosspiece. Use as a cross. At this time, the crosspiece A does not use the surface having the solar cell module fixing screw holes 7d used when it was a horizontal crosspiece, but uses the surface having the crosspiece fixing elongated hole 7d, and the crosspiece B uses the crosspiece. The surface having the fixing long hole 7d is not used, but the surface having the solar cell module fixing screw hole 7d is used. The assembling of the respective parts is carried out in the same procedure, and thus the description thereof will be omitted. In this case, the solar cell modules M are arranged vertically.

By the way, as shown in FIG. 8, in the case of a house in which a solar power generation system has already been installed, for example, when the solar cell module M is horizontally arranged, it is not possible to secure a space that is vertically long and has three stages. Therefore, only eight solar cell modules can be installed, but if the solar cell modules M are rearranged vertically as shown in FIG. 6, the number of solar cell modules can be increased to ten. Therefore, when adding a solar cell module after installation is complete,
The crosspieces A and B that have already been used are used by changing the roles of the vertical crosspiece and the horizontal crosspiece, respectively. At that time, if the length of the crosspiece is long, it may be cut, and if it is short, reinforcing material may be added to add it, but if there are too many addition points and the processing man-hour increases, it is better to use a new crosspiece. desirable. By doing so, it is possible to minimize the member of the crosspiece, the transportation cost, and the like required for adding the solar cell module.

Further, although the solar cell array using the solar cell module has been described in the above-mentioned embodiment, it may be applied to a solar heat utilization system utilizing a solar light utilization means such as a heat collector and installed on the roof. The present invention can be suitably applied to a supporting member of various solar light utilizing means described above, and can be appropriately modified and implemented without departing from the scope of the present invention.

[0030]

As described above in detail, according to the solar light utilization array of the present invention, the support member for fixing a plurality of solar light utilization means is a common solar light which can fix the solar light utilization means. By providing a light utilization means installation surface and a common support member installation surface on which another support member can be placed and fixed,
For example, vertical rails that are installed on the roof surface in parallel with each other along the direction of inclination, a plurality of horizontal rails that are mounted and fixed in parallel on a plurality of vertical rails, and a plane rectangular shape that is fixed to the horizontal rails. In the shape solar light utilization means, the solar light utilization means can be fixed to the horizontal rail on either long side or short side, and at the same time, the vertical rail can be used as the horizontal rail and the horizontal rail can be used as the vertical rail. Therefore, even when the installation direction of the solar light utilizing means is changed, the supporting member can be realized by parts of the same standard.

Further, it is not necessary for the operator of the array using solar power to correctly select the shape of the vertical and horizontal crosspieces necessary for the site from among several types,
Moreover, it is possible to reduce the time and effort required for the management as much as possible.

Further, even if the solar light utilization means is changed from a horizontally long arrangement to a vertically long arrangement in order to increase the number of solar light utilization means, simply changing the arrangement of the vertical crosspieces and the horizontal crosspieces,
It is possible to use it as a member other than the additional component, and it is possible to provide a solar array that is excellent in versatility and workability.
