Description

  The present invention relates to a roof structure in which a photovoltaic power generation panel is installed on at least one roof surface of the roof, and a construction method thereof.

  In recent years, interest in global environmental issues and energy issues has increased, and from the standpoint of using natural energy, solar panels have been installed to use solar power generation systems on tiled roofs such as Japanese tiles. There are many more. In this case, in order to leave the characteristics of the tiled roof, the photovoltaic power generation panel is often installed in the central region leaving the tiled part around the roof surface.

  Conventionally, when installing a photovoltaic power generation panel on an existing tiled roof, as in the example of Patent Document 1, the roofing material such as a roof tile is left as it is, and the photovoltaic power generation panel is supported and installed thereon. Was common. In this case, it is necessary to fix the supporting material for supporting and fixing the photovoltaic power generation panel to the roof plate or the rafter constituting the roof base by penetrating the roofing material or removing the roofing material of the part. It requires a special support structure and is difficult to install in consideration of the waterproof property of the roof. In addition, since the photovoltaic power generation panel is supported to protrude higher than the roof surface portion of the tiled roof, the entire roof surface is looked up from the front even if the roof surface portion of the tiled roof is left in the peripheral portion. In some cases, the part of the photovoltaic panel is conspicuously visible, detracting from the appearance of the tiled roof, and is very unpleasant.

  In addition, when installing a photovoltaic power generation panel on a newly built or existing tiled roof, as seen in Patent Document 2, for example, tiles in the installation area of the photovoltaic power generation panel on the roof surface (also simply referred to as panel installation area), etc. A waterproof sheet-like mounting panel is fixed to the roof base with the roofing material removed with an adhesive, a solar cell module is mounted on the top surface of the mounting panel, and a rainwater passage is formed below the mounting panel. It has been proposed to hold and install in a secure manner.

  In this case, in addition to the roof surface part other than the panel installation area, that is, the eaves area that extends forward and downward from the panel installation area, the roof surface part adjacent to the upper part of the panel installation area and the left and right side parts has the original tiled structure. The height from the roof base surface to the roof top surface is not so high. Therefore, the solar power generation panel composed of the solar cell module installed with the air passage and the rainwater passage in the lower part protrudes higher than the other roof surface portion, and the roof surface is also looked up from the front. In this case, even if the solar power generation panel is conspicuous and a tiled roof surface part is left in the peripheral part, the appearance of the tiled roof is damaged, and it is very unnatural.

  Instead of the mounting panel described above, a metal roofing material is laid on the roof base, and a solar power generation panel is installed on the metal roofing material. Although it is conceivable, the same problem as described above also occurs in this case.

  Even in the case of a slate roof or metal roof, if a solar power generation panel is installed in a part of the area, the solar power generation panel becomes considerably high with respect to the peripheral roof surface part, and the appearance is not good. Appearance.

  Next, embodiments of the present invention will be described based on examples shown in the drawings.

  The photovoltaic power generation panel P installed and used on the roof surface in the present invention is substantially the same as the configuration of the conventional photovoltaic power generation panel, and includes a solar cell module including a plurality of solar cells, and a frame that supports the peripheral portion thereof. Therefore, since a conventionally known structure can be used as it is, a detailed description thereof is omitted here.

  In at least one roof surface 1 of the tiled roof, the photovoltaic power generation panel P is placed on a predetermined region of the roof surface 1, for example, in a central region excluding the peripheral portion of the roof surface 1 as shown in FIG. With the roof material 2 removed, the solar power generation panels P are installed side by side in the vertical and horizontal directions, and the roof material 2 is installed in other areas. The first embodiment of FIGS. 1 to 6 shows a case of a tiled roof in which tiles 2 a are installed as the roofing material 2. Reference numeral 3 in the figure denotes an area where the photovoltaic power generation panel P is installed (in the present invention, it is referred to as a panel installation area), 4 denotes an eaves area that continues to the front lower side of the panel installation area 3, Reference numeral 5 denotes both side regions, and 6 denotes an upper region.

  The basic structure of the roof is the same as in the past, and rafters 7 extending from the ridge toward the eaves are arranged in parallel in the horizontal direction perpendicular to the gradient direction (vertical direction) of the roof surface at the required interval. A lower base plate 8 is laid on the base plate 8 and, if necessary, a roofing material 9 such as a waterproof sheet is laid on the lower base plate 8 to form the original first roof base 10 by the lower base plate 8. Has been.

  In the case of the present invention, the roof surface 1 on which the photovoltaic power generation panel P is installed has the longitudinal core material 11 arranged in parallel with the required distance in the horizontal direction on the first roof base 10 by the lower base plate 8 over the entire surface. Has been placed. The arrangement of the vertical core member 11 can be set as appropriate. However, in practice, it is preferable to arrange the vertical core member 11 at a position corresponding to the rafter 7 and fix it to the rafter 7 in order to maintain support strength.

  And the roof surface part of each said area | region other than the panel installation area | region 3 in the roof surface 1 where the vertical core material 11 is arrange | positioned, ie, each roof surface part of the said eaves area | region 4, the side part area | regions 5, 5, and the upper area | region 6. In this case, an upper base plate 12 is laid on the vertical core member 11, and a roofing member 13 such as a waterproof sheet is laid on the upper base plate 12 as necessary. A foundation 14 is formed, and a tile 2a as a roofing material 2 is installed on the second roof foundation 14, that is, the roof foundation 14 positioned higher than the original first roof foundation 10 to form a tiled structure. There is no. In the case of this embodiment, the tile 2a as the roofing material 2 is installed by a so-called hooking method in which the roofing material 2 is hooked to the horizontal railing 15 arranged on the second roof base 14. A space 16 corresponding to the height of the vertical core member 11 is provided between the first roof base 10 and the second roof base 14.

  In the panel installation area 3, a thin plate-like roof material 17 covering the surfaces of the vertical core material 11 and the first roof base 10 along the same is laid and covered with the thin plate-like roof material 17. The solar power generation panel P is installed on the vertical core member 11 so as to have a gap 18 below it. The thin plate-like roof material 17 has a convex shape corresponding to the vertical core material 11 at the vertical core material 11, and the gap 18 is formed on the thin plate-like roof material 17.

  In the case of the illustrated embodiment, the sheet-like roof material 17 is continuous with the panel installation area 3 and the eaves area 4 that extends below the front thereof, and the surfaces of the vertical core material 11 and the first roof base 10. The second roof base 14 by the upper base plate 12 of the eaves edge region 4 is provided on the vertical core member 11 covered with the thin plate-like roof material 17. . Thereby, the space | gap 18 held under the photovoltaic power generation panel P of the said panel installation area | region 3 is connected to the eaves 19 through the space | gap 16 under the said 2nd roof base | substrate 14, The inside of the said panel installation area | region 3 Rain water or the like can flow to the eaves 19 through the gap 16 under the second roof base 14. Usually, a gutter (not shown) is provided at the eaves portion.

  As the thin plate-like roof material 17, a metal roof material such as an iron plate such as tin or a steel plate or a copper plate is processed and laid and used along the surfaces of the vertical core material 11 and the first roof base 10. A sheet-like roof material such as a waterproof sheet can be used alone or in combination, but the ease and strength of sheet metal processing along the surfaces of the vertical core material 11 and the first roof base 10 In view of the above, a metal roofing material is particularly preferably used.

  When a metal roof material is used as the thin plate-like roof material 17, it is not always necessary to use a single metal plate material over the entire panel installation region 3, and the waterproof effect of a plurality of metal plate materials is impaired. It can be configured in combination so as not to. Usually, since the metal roofing material is processed from a long metal plate material having a predetermined width, in use as the thin plate-like roofing material 17 in the panel installation region 3, it is mainly continuous in the roof gradient direction. It is desirable that a plurality of pieces are connected in the lateral direction of the roof.

  For example, as shown in FIG. 6, metal plate members 25 separately formed with each vertical core member 11 or every other or plural vertical core members 11 as a boundary are arranged between the vertical core members 11, 11 serving as the boundary. The side end portion 25a is bent upright along the side surface of the vertical core member 11, and the metal plate material 26 processed into a concave shape in the vertical core member 11 portion is attached to the vertical core member 11. It covers so that it may be clamped from the outside of the side end portion 25a along both side surfaces, and is fixed to the vertical core member 11 with wood screws, screw nails or the like (not shown). This facilitates processing and construction of the metal roofing material.

  The thin plate-like roofing material 17 has edge portions 17a on both left and right side edges, the roofs of both side regions 5, 5 adjacent to the left and right sides of the panel installation region 3 or both the left and right sides of the panel installation region 3 and the eaves region 4. It ends under the second roof base 14 of the surface portion, bends upward and rises up, and in the case of wind and rain, the rainwater in the panel installation area 3 becomes the second roof base of the other roof surface portion. 14 is formed so as to drain water when entering under 14 so that rain leakage can be prevented. The edge 17b at the upper end of the thin plate roof material 17 is also inserted under the second roof base 14 in the roof surface portion of the upper region 6, and the thin plate roof material 17 and the second roof base in this portion are inserted. 14 is filled with plaster 20 for face doors so that rainwater does not enter the upper part.

  In addition, the space | interval dimension of the direction orthogonal to the roof surface of the space | gap 16 under the said 2nd roof base | substrate 12 and the space | gap 18 under the photovoltaic power generation panel P is suitably with the height dimension of the said vertical core material 11. For example, it is set in the range of 1.0 to 3.0 cm, but it is of course possible to set the dimensions outside the above range.

  As means for fixing and supporting the solar power generation panel P to the portion of the vertical core member 11, for example, as shown in FIG. Is fixed to the vertical core member 11, the lower base plate 8 and the rafter 7 with a fixing tool 21 such as a wood screw, a screw nail, or a bolt, and the vertical core member 11 is placed on the vertical core member 11. Various fixing means can be used, such as arranging a transverse frame material (not shown) to cross and fixing the photovoltaic power generation panel P with the frame material.

  Reference numeral 24 in the drawing is a covering protective material made of a metal plate covered at the upper end of the eaves area 4, that is, at the end on the panel installation area 3 side, and rainwater is placed between the second roof base 14 and the roofing material 2. Is to prevent the intrusion and protect the end.

  Note that the thin roof material 17 is laid only in the panel installation region 3, and rainwater flowing on the thin roof material 17 in the panel installation region 3 flows out to the upper surface of the roof material 2 in the eaves region 4. However, in this case, it is necessary to process the lower end portion of the thin plate-like roof material 17 into a shape that can guide rainwater to the upper surface of the roof material in the eaves region 4. In the case of a tiled roof having a complicated shape on the top surface of the roofing material, the thin plate-like roofing material 17 is laid in the eaves region 4 continuously to the panel installation region 3 as in the above-described embodiment, and rainwater or the like is provided. It is preferable that the air gap 15 below the second roof base 14 in the eaves area flows.

  8 and 9 show a second embodiment of a slate thatched roof. This second embodiment is basically the same as the first embodiment described above except that the slate 2b is used as the roofing material 2, so that the same components and components are denoted by the same reference numerals. Detailed description is omitted.

  The outline of the second embodiment will be described. The roof surface 1 on which the photovoltaic power generation panel P is installed has a horizontal required distance on the first roof base 10 by the lower base plate 8 and the roofing material 9 over the entire surface. A vertical core member 11 is arranged in parallel with each other. In addition, the roof surface portions of the eaves region 4, the side regions 5, 5, and the upper region 6 other than the panel installation region 3 are formed by the upper base plate 12 and the roofing material 13 on the vertical core material 11. Two roof bases 14 are provided, and a plate-like slate 2b as a roofing material 2 is provided on the roof base 14 to form a so-called slate-fired roof structure. A gap 16 is held under the second roof base 14.

  Moreover, the metal which covers the surface of the 1st roof base | substrate 10 by the said vertical core material 11 and the lower field board 8 in the panel installation area | region 3 of the said roof surface 1, and the eaves edge area | region 4 following the front lower part along this. A thin plate-like roof material 17 such as a roof-made roof material is continuously laid in the both regions 3 and 4. Therefore, in the eaves edge region 4, the second roof base 14 made of the upper base plate 12 and the roofing material 13 is provided on the vertical core material 11 covered with the thin plate-like roof material 17. The laying form and edge processing of the thin plate roof material 17 are the same as those in the first embodiment.

  In the case of this slate-roofed roof, a climbing tree 22 is arranged at the end of each roof surface portion of both side areas 5 and 5 on the panel installation area 3 side, and the climbing tree 22 is covered and the slate 2b. A metal edge member 23 is provided so as to protect the end of the slate 2b and to be waterproofed. The upper end portion of the eaves area 4 is covered with a covering protective material 24 made of a metal plate.

  The roof with the photovoltaic power generation panel as described above can be constructed mainly as follows on a newly built roof, a modified roof, and the like.

  In the case of a new roof, first, a first roof base 10 in which a roofing material 9 is laid on the lower base plate 8 is formed over the entire roof surface 1 on which the photovoltaic power generation panel P is installed. On the first roof base 10, the vertical core member 11 is arranged in parallel with the required distance in the horizontal direction. At this time, the vertical core member 11 is arranged and fixed in accordance with the position of the rafter 7. In this way, in the panel installation region 3 and the eaves region 4 that extends below the front thereof, the thin roof material 17 that covers the surfaces of the vertical core member 11 and the first roof base 10 along this is provided in the regions 3 and 4. Lay continuously.

  Next, an upper base plate 12 is laid on the vertical core member 11 in the roof surface portions of the eaves region 4, the side regions 5, 5, and the upper region 6 other than the panel installation region 3, and the roofing material 13 And a second roof base 14 is provided. In particular, in the eaves area 4, the second roof base 14 is provided on the vertical core material 11 covered with the thin plate-like roof material 17.

  Then, the roof material 2 is installed on the second roof base 14 of each roof surface portion of the eaves region 4, the side regions 5, 5, and the upper region 6 other than the panel installation region 3. For example, in the case of a tiled roof, a tile 2a as a roofing material is installed by hooking as shown in FIGS. 2 and 4, and a process such as covering the upper end portion of the eaves region 4 with a covering protective material 24 is performed. . In the case of a slate-roofed roof, the slate 2b as a roofing material is installed as shown in FIGS. 8 and 9, and the metal edge member 23 is provided at the end of the both side regions 5 and 5 on the panel installation region side. And a necessary finishing process such as covering the upper end of the eaves area 4 with the covering protective material 24 is performed.
