Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a solar cell roof, and can be used for general buildings having solar cells installed on the roof.

[0002]

BACKGROUND ART In modern life, electric power is used for various operations such as lighting, heating, power, cooling and heating,
Usually, these electric power sources are supplied from public commercial power sources. On the other hand, conventionally, solar energy has been known as energy that does not affect the environment and ecosystem, and solar power generation using a solar cell is adopted to convert this solar energy into electric power and use it. . In recent years, as the power generation efficiency of solar cells has improved and the price has dropped, solar cells have been installed in buildings such as ordinary houses and offices. The solar cell is provided as a panel having a predetermined standard size, and a predetermined number of solar cell panels are arranged when arranged on the roof surface.

The surface of the solar cell panel is mainly formed of non-combustible glass or the like, and by covering the roof surface with such a solar cell panel, the non-combustibility of the roof is secured. On the other hand, the noncombustibility of the solar cell roof is further improved by disposing a noncombustible material on the roof surface covered with the solar cell panel.

As a structure of such a solar cell roof,
There is a structure as shown in FIG. In FIG. 9, a solar cell roof 10 has support members 12 installed on a roof surface 11 so that both side edges of the solar cell panel 13 are supported and arranged, and a colored asbestos board is placed on the roof surface 11 below the solar cell panel 13. 14A and the base iron plate 14B are stretched to form the incombustible layer 14.

When forming such a solar cell roof 10, first, a base iron plate 14B made of a long iron plate is provided in a slope direction of the roof surface 11 on the roof surface 11 having a slope formed by the base plate 11A. Placed along this base iron plate 14
A pair of slender rail-like support members 12 is mounted on the roof surface 1
Install along the gradient direction of 1. Next, a commercially available colored asbestos board is cut into a size corresponding to the installation interval 1 of the pair of support members 12, and the cut colored asbestos board 14A is laid one by one on the roof surface 11 sandwiched between the pair of support members 12. To do.

Then, the arranged colored asbestos boards 14A are used as scaffolds, and the pair of support members 12 are made to support the both side edges of the solar cell panel 13 to perform the arrangement sequentially. According to such a solar cell roof 10, since the non-combustible layer 14 made of the base iron plate 14B and the colored asbestos board 14A is formed on the roof surface 11, the non-combustibility of the solar cell roof 10 is ensured, and
The colored asbestos board 14A makes it possible to obtain a stable scaffold that is not slippery, and the solar cell panel 13 can be arranged smoothly.

[0007]

However, in such a solar cell roof 10, a colored asbestos board 14 is used as the non-combustible layer 14.
Since the A and the base iron plate 14B are separately installed, there is a problem that the construction work is complicated and time-consuming. In order to solve this problem, it is conceivable to form the non-combustible layer only with an iron plate, but the roof surface laid with a flat iron plate is slippery,
There is a problem that the solar cell panels cannot be arranged smoothly. Alternatively, it is conceivable to form the noncombustible layer only with the colored asbestos plate, but since the colored asbestos plate is relatively expensive, there is a problem that the noncombustible layer cannot be formed at low cost.

An object of the present invention is to provide a solar cell roof which can secure sufficient noncombustibility and can be formed quickly and easily at low cost.

[0009]

The present invention will be described with reference to the drawings. A plurality of solar cell panels 13 having a predetermined size are arranged along a roof surface 11 and side edges of the solar cell panels 13 are supported. Solar cell roof 2 having support member 12
The roof surface 11 is covered with a non-combustible surface material 20 having scaffolding projections 21 formed on the surface thereof, and the support member 12 is installed on the non-combustible surface material 20. Is characterized by.

The supporting member 12 may be a rail-shaped long member or a plurality of members arranged in a certain direction. The non-combustible surface material 20 is a non-combustible surface material 20 such as an iron plate, a gypsum board, or a siding material.
It can be formed by 0.

By doing so, one kind of non-combustible face material 2
It becomes possible to form a non-combustible layer on the roof surface 11 simply by sticking 0 to the roof surface 11, and the construction work is simplified, and it is quicker and easier than the case where two asbestos boards and iron plates are constructed as described above. A non-combustible layer can be formed. Further, since the scaffolding projections 21 are formed on the surface of the non-combustible surface material 20, it becomes possible to secure a stable scaffold even when an iron plate or the like is used as the non-combustible surface material 200, and the solar cell panel 13 The arrangement work of can be performed quickly and smoothly.

The solar cell panel 1 is provided on the roof surface 11.
Since the noncombustible layer made of glass or the like used for the surface material of No. 3 and the noncombustible layer made of the noncombustible surface material 20 are formed, the noncombustibility of the solar cell roof 2 can be further improved. further,
Since the non-combustible face material 20 can be formed of a material other than the colored asbestos board, the non-combustible layer can be formed at a lower cost than when a colored asbestos board is used. With these, the above object is achieved.

At this time, it is preferable that the roof surface 11 has a slope and the scaffolding protrusion 21 is a ridge 21A extending in the slope intersecting direction. According to this, since the projections 21 for scaffolding are continuously formed in the slope crossing direction of the roof surface 11, a relatively large number of portions that can be used as scaffolding can be secured, and thus the scaffolding projections 21 can be placed at any position on the roof surface 11. The scaffold can be formed, and the work of arranging the solar cell panels 13 can be smoothly performed.

Further, it is desirable that the scaffolding protrusions 21 are formed at least at positions where they do not overlap the supporting member 12. By doing so, the support member 12 can be installed on the flat surface portion of the non-combustible face material 20, and the support member 12 can be reliably fixed through the non-combustible face material 20.

The non-combustible face material 20 is the non-combustible face material 2
The scaffolding protrusion 21 may be formed by bending 00 into a corrugated plate shape. By doing so, it becomes possible to easily form the scaffolding protrusions 21 continuous in one direction by bending the non-combustible face material 200 such as an iron plate, so that a relatively large scaffolding protrusion 21 can be easily obtained. To be Further, by cutting out a part of such continuous scaffolding protrusions 21, it is possible to efficiently form a plurality of intermittent scaffolding protrusions 21. Further, the scaffolding protrusion 21 can be formed only by the simple noncombustible face material 20 without using another member, and the number of members can be suppressed.

It is desirable that the portion of the above-mentioned scaffolding protrusion 21 that overlaps the support member 12 be cut out. According to this, it becomes possible to install the support member 12 on the flat surface portion of the non-combustible face material 20, and to fix the support member 12 on the non-combustible face material 20 in a stable and reliable manner. it can. In addition, in order to form a continuous non-combustible layer on the roof surface 11, it is preferable that the end portions of the notched scaffolding protrusions 21 be closed. Here, the support member 12 may be attached and closed so as to be in close contact with the notched end portion,
It is difficult to obtain such accuracy. On the other hand, for example, the cap 211 made of a non-combustible material is attached to the scaffolding
The notched end can be easily closed by, for example, fitting it into the end.

The non-combustible face material 20 is a non-combustible face material 20.
The scaffolding protrusion 21 may be formed by bulging 0 from one surface side to the opposite surface side. Alternatively, the non-combustible face material 20 may have the scaffolding protrusion 21 formed by joining another member 21 </ b> B to the non-combustible face material 200.

By doing so, the scaffolding protrusion 2
The shape, arrangement, etc. of 1 can be arbitrarily set. Therefore, the scaffolding protrusions 21 can be easily formed in a shape and a position that do not overlap the support member 12.

When the non-combustible face material 200 is bulged to form the scaffolding protrusions 21, the non-combustible face material 20 can be formed without using any member other than the non-combustible face material 200. Can be suppressed.

When the scaffolding protrusion 21 is formed by joining another member 21B to the non-combustible face material 200, the scaffolding protrusion 21 can be easily formed by adhesion or the like, so that the non-combustible face material 20 is formed. The equipment to be used is simplified. The separate member 21B does not have to be a noncombustible material.

It is desirable that the scaffolding protrusion 21 has a tapered shape and the inner shape is along the outer shape of the other scaffolding protrusion 21. Examples of such scaffolding protrusions 21 include those having a trapezoidal cross section or a triangular cross section. According to this, even if a plurality of non-combustible face materials 20 having the same shape are stacked, the scaffolding protrusions 21 can fit inside the other scaffolding protrusions 21, and the non-combustible face material 20 can be stably and relatively large in number. It can be stacked and requires less space for storage and transportation.

In addition, the wiring opening 2 is formed in the non-combustible face material 20.
3 may be formed, and a cylindrical portion 24 continuous with the wiring opening 23 may be formed in the vicinity of the peripheral edge of the wiring opening 23. The tubular portion 24 is formed on the non-combustible face material 20 by the tubular member 2
It can be formed by fixing 4A. An upper surface opening 242 is formed in the upper part of the tubular portion 24, and a wiring hole is formed in the roof surface 11 at a position corresponding to the wiring opening 23. It is preferable that the space communicates with the inside of the building.

By doing so, the solar cell panel 1
It is possible to introduce a cable 132 or the like that extends to the lower side of the power supply 3 from the upper surface opening 242 in the upper portion of the tubular portion 24 and guide it through the wiring opening 23 to the inside of the building through the wiring opening 23. Moreover, since wiring can be performed by penetrating the non-combustible face material 20, the wiring work can be performed quickly. Further, since the wiring opening 23 is formed inside the tubular portion 24, and the tubular portion 24 is formed so as to rise from the noncombustible face material 20, the solar cell panel 1
It is possible to prevent rainwater or the like that has entered the space below 3 from flowing over the incombustible surface material 20 and into the wiring opening 23. In addition, the tubular portion 24 can be used as a scaffold when the solar cell panels 13 are arranged.

Here, when the tubular portion 24 is formed in advance at the factory, it is preferable that the tubular portion 24 has a tapered shape. According to this, it becomes possible to stably stack the non-combustible face materials 20, and it is possible to transport or store the plurality of stacked non-combustible surface materials 20 to the construction site.

A head member 244 is attached to the upper portion of the tubular portion 24 described above, and a gap of a predetermined interval is formed between the upper end of the tubular portion 24 and the upper surface back side of the head member 244. The outer periphery of the head member 244 is the cylindrical portion 2
4 is arranged at a predetermined distance outside the outer circumference of 4, and
4 may have a hanging portion 245 extending below the upper end of the tubular portion 24. The attachment of the headstock member 244 to the tubular portion 24 as described above is performed by the pillar 2
It can be performed by joining via 49. The planar shape of the head member 244 is preferably larger than the tubular portion 24.

By doing so, even if rainwater or the like enters the space below the solar cell panel 13 and is blown up or down by the wind or the like, the head member 24.
4 prevents water from entering the wiring opening 23.
Further, since the cross-sectional area of the passage communicating from the upper surface opening 242 to the outside can be secured sufficiently large, the wiring work performed through the upper surface opening 242 can be performed quickly and easily, and the space between the solar cell panel 13 and the noncombustible surface material 20 can be increased. Ventilation for cooling the solar cell panel 13 performed in 1 can be smoothly performed.

Further, it is desirable that the plane shape of the non-combustible surface material 20 corresponds to the plane shape of the solar cell panel 13. For example, if the standard size of the solar cell panel 13 is a square with one side P, the nonflammable face material 20 also has one side K =.
P or a square of K = P / 2, and so on. The standard size is mainly the arrangement pitch, and adjacent solar cell panels 1
In the case where a sealing material or the like is filled in between 3 and 3, or the end portions of the solar cell panel 13 are overlapped, the standard size and the actual size are different. According to this, the number of installed non-combustible surface materials 20 can be set together with the number of installed solar cell panels 13, and the number of installed non-combustible surface materials 20 according to the size of the roof surface 11 and the number of installed solar cell panels 13. The time and effort for setting the size and shape separately are eliminated, and the incombustible layer can be reliably formed.

The incombustible face material 20 is preferably formed of an iron plate. According to this, since the iron plate can be easily shaped by bending or pressing, the scaffolding protrusion 21 having a desired shape can be easily formed by a desired processing method. Since the colored asbestos plate described above has flexibility, it is not possible to stably fix the support member 12 and it is relatively expensive. However, when an iron plate is used, the support member 12 can be securely fixed because it has rigidity. It can be done and cost reduction is achieved.

The non-combustible face material 20 is composed of scaffolding protrusions 21 and planar portions 22, and is formed by bending an iron plate 200 which is a non-combustible face material so that these are alternately arranged in the longitudinal direction.

The scaffolding projection 21 is a tapered ridge 21A extending in the width direction of the non-combustible surface material 20, has a substantially trapezoidal cross section, and the inner shape is along the outer shape of the other scaffolding projection 21. There is. Since the supporting member 12 is fixed on the boundary line between the adjacent non-combustible surface materials 20, the supporting member 1 of the scaffolding protrusion 21 is fixed.
The vicinity of the edge overlapping with 2 is cut out, and a cap 211 is fitted and closed at the cut edge.
The cap 211 is made of an incombustible material such as an iron plate or an inorganic surface material (such as an asbestos plate), and is fixed by press fitting or adhesion.

A wiring opening 23 is formed in the planar portion 22 of the incombustible surface material 20 arranged on the eaves side, and an iron tubular member having a substantially trapezoidal cross section is formed at the peripheral edge of the wiring opening 23. Two
4A is joined to form a tapered cylindrical portion 24. The cylindrical member 24A has an upper surface opening 242 on its upper surface, and a collar portion 241 extending from each side surface is riveted to the planar portion 22.

The transportation and storage of such noncombustible face materials 20 are carried out in a stacked state. At this time, the scaffolding protrusion 21 and the tubular portion 24 are replaced by the other scaffolding protrusion 21 and the tubular portion 2.
Stack so that it fits inside 4.

Support member 1 for supporting solar cell panel 13
Reference numeral 2 denotes a long and slender rail-shaped material, which is installed on the non-combustible surface material 20 in parallel along the gradient direction at intervals according to the width of the solar cell panel 13. The support member 12 is a support part 121 that supports the side edges of the two solar cell panels 13.
A, and the gutter-shaped portion 1 formed on the lower surface side of the support portion 121.
22 and the leg 12 formed below the gutter 122.
3 is provided. The support portion 121 is formed in a gutter shape having a substantially U-shaped cross section, supports the adjacent solar cell panels 13 on the lower surface thereof, and allows leakage of water leaked from the solar cell panel 13 side to flow toward the eaves for drainage. It has become.

The trough portion 122 has a substantially trapezoidal cross section, is integrally formed with the support portion 121 on the lower surface of the support portion 121, and is capable of draining water leaking from the support portion 121 toward the eaves. The leg portion 123 is formed so as to extend vertically from the lower surface of the gutter-shaped portion 122, and includes a bottom plate 123A. Attach the bottom plate 123A to the planar portion 22 and the base plate 11 with screws 1
By fixing with 24, the support member 13 is installed along the roof surface 11.

The solar cell panel 13 has a predetermined number of solar cells contained in a flat case,
Glass is used as the surface material. Solar panel 1
3 is a square in which the standard size P is 1 module (M) in length and width, and the actual size S is set smaller than the standard size P. At the opposite side edges of the solar cell panel 13, continuous rising portions 131 extending downward are formed. The solar cell panel 13 is supported by the pair of support members 12 at both ends via the rising portion 131, and a gap is formed between the solar cell panel 13 and the non-combustible surface material 20. Air for cooling the panel 13 is designed to flow. A cable 132 for taking out electric power extends from the solar cell panel 13 and is introduced into the building through the wiring opening 23.

In this embodiment having such a configuration, the solar cell roof 2 is constructed in the following procedure.
First, the non-combustible face material 20 is abutted against the adjacent non-combustible face material 20 on the roof surface 11 formed by the base plate 11 </ b> A without any gap, and a non-combustible layer is formed along the gradient direction. At this time, since the non-combustible face material 20 is a square with the dimension K = P, the number of non-combustible face materials 20 installed is the same as that of the solar cell panel 1.
It is the same as the number of installations of 3. In addition, since the actual size S of the solar cell panel 13 is shorter than the standard size P, a gap is formed between the adjacent solar cell panels 13, and the roof surface 11 is filled with a sealing material (not shown) or the like. To prevent water leakage. Next, the support member 12 is arranged along the boundary line between the adjacent non-combustible surface materials 20, the bottom surface 123A is fixed to the planar portion 22 with the screw 124, and the support member 12 is fixed to the roof surface 11.
Install along the gradient direction of. At this time, the non-combustible surface material 2
Since the dimension K of 0 corresponds to the dimension P of the solar cell panel 13, the support members 12 are installed with a predetermined interval according to the width of the solar cell panel 13. Also, the scaffolding protrusion 2
1 extends continuously through the support member 12 in the girder direction.

Next, the scaffolding protrusion 21 and the tubular portion 2
4 is used as a scaffold, and the support portions 1 of the pair of support members 12 are used.
On the lower surface of 21, the rising portion 131 of the solar cell panel 13
The lower ends of are fixed and are sequentially arranged along the roof surface 11 in the gradient direction. Then, the cable 132 is guided from the upper surface opening 242 into the tubular member 24A, and the wiring opening 23 is formed.
Through the wiring hole (not shown) formed in the base plate 11A through the wiring board into the building for wiring work.

According to the present embodiment, the following effects can be obtained. That is, the non-combustible layer can be formed on the roof surface 11 quickly and easily by simply sticking one kind of non-combustible surface material 20 to the roof surface 11. Also,
Since the scaffolding protrusions 21 are formed on the non-combustible surface material 20, a stable scaffold is secured even with the non-combustible surface material 20 made of iron, and the work of arranging the solar cell panels 13 can be performed quickly and smoothly. Since a non-combustible layer made of glass used for the surface material of the solar cell panel 13 and a non-combustible layer made of the non-combustible surface material 20 are formed on the roof surface 11, the roof surface 11
It becomes possible to further improve the non-combustibility of. Furthermore, since the non-combustible face material 20 is formed of the iron plate 200 which is a non-combustible face material, the non-combustible layer can be formed at a lower cost than a colored asbestos plate or the like.

Further, since the scaffolding projections 21 are continuously formed in the girder direction of the roof surface 11, the roof surface 11 can be widely used as a scaffolding, so that the arrangement work of the solar cell panels 13 can be performed smoothly. it can. And the scaffolding protrusion 21
Is formed by bending an iron plate into a corrugated plate shape, it is possible to easily form a relatively large scaffolding protrusion 21 continuous in one direction and to form the scaffolding protrusion 21 only with the non-combustible face material 200. Furthermore, since the end of the scaffolding protrusion 21 that overlaps the support member 12 is cut out, and the support member 12 can be installed on the flat surface-shaped portion 22, the support member 12 can be fixed onto the non-combustible face material 20. It can be stable and reliable. In addition, the scaffolding protrusions 21 have a substantially trapezoidal cross section and the inner shape is along the outer shape of the other scaffolding protrusions 21, so that they can be stacked and occupy less space during storage and transportation.

Since the wiring opening 23 surrounded by the cylindrical portion 24 having the upper surface opening 242 is formed in the non-combustible surface material 20, the cable 132 is introduced from the upper surface opening 242 to be used for wiring. It can be guided to the inside of the building through the opening 23, and the wiring work can be performed quickly. Also, the tubular portion 24
Rainwater or the like that has entered the space below the solar cell panel 13 due to the side surface of the
It is possible to avoid flowing into 3. And the tubular portion 24
Since it has a tapered shape, it is possible to stably stack and store and transport a plurality of these noncombustible face materials 20. In addition, the tubular portion 24 can be used as a scaffold when the solar cell panels 13 are arranged.

Furthermore, since the dimension K of the non-combustible surface material 20 is the same as the standard dimension P of the solar cell panel 13, it is sufficient to prepare the same number of non-combustible surface materials 20 as the number of installed solar cell panels 13. There is no need to separately set the dimensions and shape of the non-combustible face material 20. Further, since the dimension K of the non-combustible surface material 20 corresponds to the standard dimension P of the solar cell 13, the standard dimension P
If is constant, the solar cell panels 13 having different actual dimensions S can be used.

Since the non-combustible surface material 20 is made of an iron plate, the scaffolding protrusion 21 can be easily formed by bending a flat iron plate, and the supporting member 1
The fixing of No. 2 can be performed more reliably than the case of fixing to the colored asbestos board, and the cost reduction can be achieved.

The present invention is not limited to the above-described embodiments, 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. For example, in the above-described embodiment, the non-combustible face material 20 is formed by bending an iron plate into a corrugated plate shape, but as shown in FIG. 21A bulged from one surface side to the other surface side
It may be formed as. By doing so, the shape, arrangement, etc. of the scaffolding protrusions 21 can be arbitrarily set, and the scaffolding protrusions 21 can be easily formed in a shape and position not overlapping the support member 12. In addition, the non-combustible face material 20
Since the non-combustible face material 20 having the scaffolding protrusions 21 can be formed only by 0, the number of members can be suppressed.

Further, as shown in FIG. 5, the prismatic separate member 2 is used as the scaffolding protrusion 21 on the non-combustible face material 200 such as an iron plate.
1B may be joined by bonding or the like to form the noncombustible face material 20, and as shown in FIG. 6, the block-shaped separate member 21B is intermittently joined to the nonflammable face material 200. The material 20 may be formed. At this time, since the non-combustible face material 200 is arranged below the separate member 21B, the separate member 21
B does not have to be nonflammable. These may be joined by, for example, adhesion with an adhesive, riveting, or soldering, and the joining method is arbitrary.

In this way, the shape and arrangement of the scaffolding protrusions 21 can be set arbitrarily, and the scaffolding protrusions 21 can be easily formed in a shape and position that does not overlap the supporting member 12. Further, since the scaffolding protrusions 21 can be easily formed by adhesion or the like, the nonflammable face material 20 can be formed with simple equipment.

Alternatively, a hollow member may be joined to the opening of the non-combustible face material to form the projection 21 for scaffolding, and the non-combustible face material may be formed. Alternatively, the non-combustible face material 20 may be formed by alternately and continuously joining the planar member formed of the non-combustible face material and the hollow member. Scaffolding protrusion 21
In addition to such pressing and adhesion, for example, when wood or siding material is used, joining with fasteners, when using resin, those formed by injection molding may be adhered, The forming method is arbitrary and may be appropriately selected according to the material used.

In the above-described embodiment, the scaffolding protrusion 21 has a substantially trapezoidal cross section and has a continuous shape in the girder direction. However, for example, as shown in FIG. It may be a ridge 21A that is continuous in the girder direction or a ridge that has a substantially triangular cross section, and may have any shape as long as it can be used as a scaffold.

In the above-described embodiment, the portion of the scaffolding protrusion 21 on which the support member 12 is installed is cut out, but the portion of the leg 123 of the supporting member 12 that overlaps the scaffolding protrusion 21 is cut out. May be. In short, it suffices if the supporting member 12 can be fixed to the planar portion 22 of the nonflammable surface material 20. Further, the support member 12 may be fixed on the scaffolding protrusion 21 without making such a notch. At this time, it is preferable that the non-combustible surface material is formed of a material having a strength capable of stably fixing the support member 12.

In the above-described embodiment, the cap 211 is fitted in the notched portion of the scaffolding protrusion 21, but the notch is formed by attaching another member such as a face material or filling a filling material. It is possible to close the end that has been cut, and the supporting member 1
After the installation of 2, the support member 12 and the notched portion may be closed with a sealing material or the like. In short, the method is arbitrary as long as the notched portion can be closed.

Further, the non-combustible face material 20 has the dimension K corresponding to the standard dimension P of the solar cell panel 13, but, for example, K = 2P or K = 2 / P, which is non-combustible. The face material may correspond to the standard dimension P of the solar cell panel having the dimension K. Further, the non-combustible face material 20 is not limited to a square shape, and may be a rectangle extending in the gradient direction of the roof surface 11 or a wide shape extending in the girder direction, and the shape (dimension K) is arbitrary.

In the above-mentioned embodiment, the non-combustible face material 20 is arranged so that the end faces of the adjacent non-combustible face material 20 are abutted against each other. However, a collar portion is formed on one edge of the non-combustible face material 20, The collar portion may be arranged on the non-combustible face material 20 adjacent to each other so as to overlap each other.

In the above-mentioned embodiment, the non-combustible face material 20 is formed of the iron plate 200 which is a non-combustible face material.
Any material having incombustibility may be used, and for example, it may be formed of gypsum board, incombustible resin, siding material, or the like, and the specific material type may be appropriately selected for implementation. However, it is preferable to use iron, which is easy to process and inexpensive, for the nonflammable face material.

In the above embodiment, the wiring opening 23 and the cylindrical portion 24 are formed in the planar portion 22, but
The wiring opening 23 may be formed in the scaffolding protrusion 21.
According to this, even if the tubular portion 24 is not separately formed, the wiring opening 2 can be easily formed in the portion rising from the planar portion 22.
3 can be formed, and invasion of water leakage can be avoided.

The tubular portion 24 was formed only by the tubular member 24A having a substantially trapezoidal cross section with the upper surface opening 242. However, as shown in FIG. 7, the tubular member 24 provided with the water shield 24B. The head member 244 may be attached to the upper portion of 24A. In FIG. 7, the head member 244 has a substantially quadrangular planar shape that is larger than the tubular member 24A, and has a hanging portion 24.
A water baffle 246 is formed along the lower end of 5. The back side of the upper surface of the head member 244 and the inner wall of the tubular member 24A are joined together via four key-shaped columns 249, and the upper surface 246 of the head member and the upper end of the tubular portion 24 are spaced at a predetermined interval. A gap is formed, and the outer periphery of the headstock member 244 is attached in a state where the outer periphery is a predetermined distance outside the outer periphery of the tubular member 24A. At this time, the lower end of the hanging portion 245 is arranged below the upper end of the tubular portion 24 formed by the tubular member 24A.

As a result, the hanging portion 245 and the cylindrical portion 24
A space is formed between A and between the cylindrical portion 24 and the upper surface of the head member 244, and a passage for communicating the outside with the inside of the cylindrical portion 24 and the inside of the building below the wiring opening 23 is formed. Through this passage, the cable 132 is guided to the upper opening 242, and is guided from the wiring opening 23 into the building. According to this, since the cross-sectional area of the passage communicating from the upper surface opening portion 242 to the outside can be formed sufficiently large, the wiring work performed through the upper surface opening portion 243 can be performed quickly and easily, and the solar cell panel 13 and the noncombustible surface material 20 can be performed. Ventilation between and can be smoothly performed. In addition, the head member 24
Since the upper surface opening portion 242 and the wiring opening portion 23 are covered with 4, water or the like may enter the wiring opening portion 23 even if water leaks from above or rainwater is blown up or down. Can be avoided.

Further, as shown in FIG. 8, a cylindrical member 24A
May be a bottomed cylindrical body having a substantially quadrangular cross section with its upper surface closed. The side surface of the cylindrical member 24A in the gradient crossing direction is cut out, and a side surface opening 243 is formed. The cable 132 is connected to the tubular member 24 through the side opening 243.

It is introduced into the building through a wiring hole (not shown) formed in the.

The tubular portion 24 is the tubular member 2 on site.
4A may be fixed by nailing or the like, and when the headstock member 244 is used, the tubular member 24A
It is also possible to join the headstock member 244 and the wood board member 244 at the factory and attach them to the non-combustible face material 20 on site. At this time, the cylindrical portion 24 does not have to have a tapered shape, and may have any shape as long as it is formed so as to rise from the planar portion 22. Further, although the tubular portion 24 is formed by riveting the tubular member 24A, it may be formed by bonding, soldering, or integrally molding with the nonflammable face material 20,
The forming method is arbitrary.

In the above-mentioned embodiment, the supporting member 12 has the supporting portion 121, the gutter-shaped portion 122 and the leg portion 123.
It may be a supporting member having another shape that does not have the gutter-shaped portion 122 or the leg portion 123. However, it is preferable that the portion of the scaffolding protrusion 21 that overlaps with the support member is appropriately cut out according to the shape of the support member. Further, the shape and performance of the solar cell panel 13 are arbitrary, and the specific type of the solar cell panel may be appropriately selected for implementation.

[0061]

As described above, according to the present invention,
By sticking one kind of non-combustible surface material to the roof surface, it is possible to form a non-combustible layer more quickly and more easily than when installing two asbestos boards and iron boards, and a stable scaffolding is secured. The arrangement work of the solar cell panels can be performed quickly and smoothly. Since the non-combustible layer made of the solar cell panel and the non-combustible layer made of the non-combustible surface material are formed on the roof surface, the non-combustibility of the solar cell roof can be further improved. Furthermore, since the non-combustible face material can be formed of a material other than the colored asbestos board, the non-combustible layer can be formed at a lower cost than when using the colored asbestos board.

Further, by forming the projections for scaffolding as the projections extending in the direction intersecting with the gradient, a relatively large number of portions that can be used as scaffolds are secured, and the work of arranging the solar cell panels can be performed smoothly. Further, by forming the scaffolding protrusion at a position where it does not overlap the support member, the support member can be securely fixed through the non-combustible surface material.

By forming the scaffolding protrusion by bending the non-combustible surface material into a corrugated plate shape, a continuous scaffolding protrusion can be easily formed and the number of members can be suppressed.

Furthermore, the projections for scaffolding are tapered,
By setting the inner shape of the scaffolding protrusion to the outer shape of other scaffolding protrusions, it is possible to store and transport a plurality of noncombustible face materials in a stacked state.
