The drainage of the solar energy conversion module integrated exterior structure in which the solar energy conversion module is introduced into a part of the roof surface. Concerning structure.

  Solar power generation, which converts light energy into electrical energy, is expected to be widely used as a means of obtaining clean energy. In recent years, it has been applied to the roofs and walls of buildings, and it is a system that supplements the power required for daily life. Has been put to practical use.

As a method of installing a solar energy conversion module such as a solar cell on a roof, a solar cell is assembled on a side-mounted exterior panel, and many roof structures using this exterior panel have been proposed. There has also been proposed a roof structure in which a solar cell is assembled to a vertical-type exterior panel and the exterior panel is used.
In Patent Document 1, water generated for various reasons on the back surface of a solar cell is discharged from a drain hole and allowed to flow down from a drainage member along the water flow direction.

JP 2007-332774 A

However, Patent Document 1 is intended for drainage of the exterior panel itself, and drainage of the entire roof surface is exclusively due to drainage members.
For this reason, for example, the roof is limited to a roof (type) in which rainwater is guided to the drainage member, and the entire surface may be repaired.

  In recent years, the number of cases in which a solar energy conversion module is introduced to only a part of the roof surface has increased. As a result, one roof surface can be divided into an exterior surface with a solar energy conversion module and an exterior surface without a solar energy conversion module. It is becoming more and more composed.

  Therefore, the present invention can be applied to a new roof or an existing roof, and does not limit the type of roof to be constructed, and a solar energy conversion module capable of introducing a solar energy conversion module to a part of various roof surfaces. It aims at providing the drainage structure of a module integrated exterior structure.

As a result, rainwater can be led from the waterproof sheet to the surface of the exterior material and allowed to flow down. And since this aspect can be easily used together with the case where the said drainage part is located higher than a foundation | substrate surface, for example, it can achieve a double rainy structure as a 2nd drainage part.

Moreover, the connection of the flow direction of panel material 1F and 1F is connected using the horizontal support material 3F provided with the vertical piece 381 which stands | starts up from the flowing water part 31F, and the horizontal piece 382 and 382 which face the flow direction in the middle of the height. . And the water lower end and water upper end of the panels 1F and 1F are supported by the horizontal pieces 382 and 382 and arranged to abut against the vertical piece 381, and an elastic water stop material 39 such as silicone rubber is arranged. Connected.

In the general structure located on the left side (under water) in FIG. 6A, the uppermost panel 9 is arranged in the space O between the base surface 4 and the drainage part 87F as described above. The rainwater flowing through the waterproof sheet 41 can be guided onto the panel 9 and can flow down along the roof surface of this general structure. Further, a substantially L-shaped eaves metal fitting 9y is attached to the water lower end of the vertical support material 8F, and the covering material 9z is attached to the eave metal fitting 9y so that the water lower edge is along the end surface of the panel 9. Installed to prevent rainwater from entering. The covering material 9z is formed with a ventilation port 91 that opens downward, and the air blown from the ventilation port 91 enters the space on the back surface side of the panel material 1F as indicated by the broken large arrow.
In the general structure located on the right side of FIG. 6B, a substantially L-shaped discard plate 9A is fixed on the side surface of the vertical support member 8F and the base 4, and the support member is placed on the discard plate 9A. 9B and the panel 9 are mounted, and a cover member 9C is attached so as to cover the support member 9B and the panel 9, and the fixing member 61 is fixed together with the cover member 6F to prevent intrusion of rainwater.

In the illustrated embodiment, the cap material 2 covering the opening edge is fitted into the through hole 40 penetrating the back surface provided in the roof base 4, and the wiring 16 of the solar energy conversion module 10 is connected to the cap material 2. A wiring lead-in structure is adopted in which the lead-in is led from the opening to the back side of the base 4 through the through hole 40.
The cap member 2 extends from a cylindrical portion 21 fitted into the through hole 40, a curved portion 22 that curves outwardly from the upper edge of the cylindrical portion 21, and a lower end of the curved portion 22. The mounting portion 23 extends along the base surface 4.

The cylindrical portion 21 is formed in a substantially cylindrical shape according to a circular hole 40 in a plan view provided in the roof base 4, and its lower edge is slightly expanded.
In addition, although the upper edge of this cylinder part 21 is expanded outside outward, this structure is mentioned later as the curved part 12. FIG.
The bending portion 22 is configured by a curved surface that curves in a convex shape outward from the upper edge of the cylindrical portion 21. This convex top is called the opening edge 221 because it is the upper end of the opening formed in a substantially bowl shape.
The attachment portion 23 extends from the lower end of the curved portion 22 and extends along the base surface 4 (waterproof sheet 41). At that time, the attachment portion 23 is bonded to the waterproof sheet material 41 through a sealing material.

In the drainage structure of FIG. 6, since the drainage portion 87F of the vertical support member 8F is positioned higher than the base surface 4 by the legs 88 as in the embodiment of FIG. 4, the base surface 4 and the drainage portion 87F The panel 9 located on the uppermost water side can be easily disposed in the space O between the two. That is, since the lower end portion of the drainage portion 87F is disposed on the panel 9 located on the upper side of the water adjacent to the underwater side, the rain water flowing down the drainage portion 87F is surely provided in the exterior structure adjacent to the underwater side. Can lead.
The space O can also be used as a space for passing a cable (not shown) by notching the underwater side of the leg portion 88 as described above, and the solar cells of the panel materials 1F and 1F adjacent in the left-right direction. Ten cables can be easily connected.

Further, in this embodiment, since the wiring 16 is drawn using the cap material 2, the wiring 16 can be exposed not only from the underwater side but also from four sides (surroundings) to the through hole 40 provided in the base 4. Since the opening edge 221 that is the convex top of the curved portion 22 of the cap material 2 is located above the mounting portion 23, the opening edge even if rainwater enters the waterproof sheet material 41 laid on the base surface 4. Inflow from 121 can be prevented.
Furthermore, since the curved portion 22 that comes into contact with the wiring 16 is formed of a curved surface, the wiring 16 does not break or be damaged due to friction.
Further, as described above, the wiring 22 can be exposed not only from the underwater side but also from four sides (surroundings), so that it is easier to use than the case where at least the wiring 16 is limited from the underwater side, and the through hole The number of holes 40 may be small.
In the illustrated embodiment, the wiring 16 is disposed so as to be bent upward by the curved portion 22 of the cap material 2, so that the condensed water adhering to the wiring 16 is connected to the outside of the hole 40. It is possible to prevent the water from entering the through hole 40.
