Description

  The present invention relates to a waterside covering material that can be combined with a photovoltaic power generation panel with a roof material.

  The prior art will be described with reference to FIGS. 5 to 7A and 7B.

  FIG. 5 is based on FIG. 5 in “Solar power generation panel with roofing material and eaves with roofing material” filed by the applicant as Japanese Patent Application No. 2011-507486. In this application, the upper side of the solar power generation panel with a roof material attached to the uppermost stage is a problem. In particular, when installing a solar power generation panel with a roofing material in a heavy snowy region, snow accumulates on the water side of the solar power generation panel with the roofing material attached to the uppermost stage. As a result, the solar power generation panel with a roof material is subjected to a force in the flow direction due to a snow load, and the snow may be frozen.

  Application of the technique shown in FIG. 6 or 7A and 7B to the technique shown in FIG. 5 can be considered. FIG. 6, FIG. 7A and FIG. 7B are draining techniques for preventing rainwater from entering a place where a photovoltaic power generation panel is fixed on a roof.

  FIG. 6 is a technique for shielding the upstream opening 12 a of the corrugated metal plate 12 with the draining metal plate 10 in the attachment in which the solar cell panel 18 is attached to the corrugated metal plate 12.

  7A and 7B show a roof structure with a solar cell panel in which an engaging piece portion 26d is formed on the module draining member 26, which is engaged with the engaging portion 23 of the horizontal frame 20, and the fixing plate This is a technique for fixing by the portion 26a.

Patent No. 4478240 Japanese Patent No. 3499725

  When the technique of FIG. 6 is applied to FIG. 5, the force plate 20 is attached and the draining metal plate 10 is locked there. Therefore, it takes time for construction. Moreover, since the draining metal plate 10 shields the upstream side opening part 12a of the corrugated metal plate 12, the drainage and ventilation which are the effect of a solar power generation panel with a roof material will be inhibited.

  In the case of applying the technique of FIG. 7A and FIG. 7B to FIG. 5, in addition to the module draining member 26, the vertical frame draining member 32 and the like are necessary. In this way, the number of members increases, and it is necessary to make them a complex combination in consideration of the rain, so that it takes time for construction. Further, in the technique of FIGS. 7A and 7B, there is a gap between the engaging piece portion 26d and the engaging portion 23, and a fastener is driven from the fixing plate portion 26a to fix the draining member for the module. Otherwise, they cannot be engaged. This is because the purpose is to press-fit the vertical frame draining member 32 under the engagement piece portion 26d.

  In addition, even when the techniques of FIGS. 7A and 7B are applied to FIG. 5, as in the case of applying the technique of FIG. Since it is shielded by the frame draining member 32 and the like, drainage and ventilation are hindered.

  In the waterside covering material of the present application, the underwater side is combined with a solar power generation panel with a roof material, and the lower surface side is combined with a drainage plate.

  The solar power generation panel with a roof material combined with the waterside covering material of the present application has a roof material in which a mountain part, a valley part, and a space communicating in the eaves direction are formed, and a water fitting part is formed on the water side. And a frame.

  The drainage plate combined with the waterside covering material of the present application has a mountain part, a valley part, and a space communicating in the eaves ridge direction, and is stacked on the waterside of the roofing material.

  The waterside covering material of the present application is a covering surface in which a fitting portion that fits into the water fitting portion of the lower roof solar power generation panel is formed on the waterside, and extends from the fitting portion to the waterside. Is formed, and a face door portion is formed which extends from the covering surface and is folded between the ridge portions of the drainage plate.

  The waterside covering material of the present application has a fastening portion that is fixed to the peak portion of the drainage plate.

  When the waterside covering material of the present application is fixed to the peak portion of the drainage plate, the face door portion is folded between the peak portion and the peak portion of the drainage plate, and the waterside end of the face door portion and the drainage plate valley A drainage gap is formed between the two parts.

  The waterside covering material of the present application can be fitted to the water fitting portion of the lower solar photovoltaic panel with roof material and fixed to the drain plate at the fastening portion, or drained at the fastening portion in advance. Since it can be attached simply by fixing the drainage plate on the roof by fitting the fitting part to the water fitting part of the photovoltaic panel with roof material in the lower stage while fixing to the board, there are few necessary members This simplifies on-site construction.

  Moreover, the waterside covering material of this application guides the snow accumulated on the waterside of the photovoltaic power generation panel with a roof material to the photovoltaic power generation panel (light receiving surface) and further to the eaves by the face door portion and the covering surface. Can do. As a result, it is possible to reduce the force in the flow direction due to a snow load, and to prevent leakage due to freezing.

  Furthermore, the waterside covering material of the present application forms a drainage gap between the waterside end of the face door and the trough of the drainage plate, so that the snow melting water can be removed from the lower roofing solar power generation panel. It can be drained through a space communicating in the direction of the eaves. At the same time, since the warmed air can be ventilated by the lower roof-covered solar power generation panel by the drain gap portion, the temperature increase of the solar power generation panel can be prevented, and the decrease in power generation efficiency can be suppressed.

Although FIG. 5 is explanatory drawing of a prior art, it is an Example of the solar power generation panel with a roof material combined with the waterside coating | covering material of this application.

  First, examples of the water-side covering material of the present application, a solar power generation panel with a roof material and a drain plate combined therewith will be described with reference to FIGS. 1 to 3 and FIG. 5.

  As shown in FIG. 3, the waterside covering material 1 of the present application is combined with a solar power generation panel B with a roofing material on the underwater side. Further, the water-side covering material 1 of the present application is combined with the drain plate 2 on the lower surface side.

  As a specific example of the solar power generation panel B with a roof material combined with the waterside covering material 1 of the present application, there is a structure as shown in FIG. It has the roofing material 5 in which the mountain part 51, the trough part 52, and the space connected in the eaves-ridge direction were formed, and the frame 6 in which the water fitting part 61 was formed in the water upper side. The roof material 5 may have a wave shape in which the mountain parts 51 and the valley parts 52 are alternately formed, or may have a shape in which the valley parts 52 are widened or a shape in which the valley parts 52 are narrowed.

  As shown in FIG. 2, the drain plate 2 has a mountain portion 21, a valley portion 22, and a space communicating with the eaves ridge direction. If the drainage plate 2 can be drained when combined with the roofing material 5 as shown in FIG. 3, the drainage plate 2 may be a corrugated shape in which the ridges 21 and the valleys 22 are alternately formed, or the valleys 22 are widened. The shape or the shape which narrowed the trough part 22 may be sufficient. In addition, it is good to use the thing of the same shape as the roofing material 5 of the photovoltaic power generation panel B with a lower roofing material as the drain plate 2. FIG.

  As shown in FIG. 3, the drainage plate 2 is overlaid on the water side of the roofing material 5 of the photovoltaic power generation panel B with the roofing material attached to the lower stage. When the invention of the present application is applied to the photovoltaic power generation panel B with the roofing material shown in FIG. 5, the photovoltaic power generation panel B with the roofing material forms the fastening portion 53 on the water side of the roofing material 5. On this, the underwater side of the drainage plate 2 is overlapped as shown in FIG. By overlapping, it will be in the state which covers the fixing part 53 of the lower roof material 5 from the top, Therefore The water stop process etc. in attachment of the photovoltaic power generation panel B with a lower roof material become unnecessary.

  As shown in FIGS. 1 and 4, the water-side covering material 1 is formed with a fitting portion 11 that fits on the water-fitting portion 61 of the photovoltaic power generation panel B with the roof material on the lower side. A covering surface 12 extending from the portion 11 to the water side is formed, and a face door portion 13 extending from the covering surface 12 and being folded between the peak portion 21 and the peak portion 21 of the drainage plate 2 is formed, It has a fastening part 141 that is fixed to the peak part 21 of the drainage plate 2. In the embodiment of FIGS. 1 and 4, an abutment surface 14 that abuts against the peak portion 21 of the drainage plate 2 is provided. A fastening portion 141 is formed on the contact surface 14.

  The fitting part 11 forms a shape that fits into the water fitting part 61 of the lower roof solar photovoltaic panel B. The fitting portion 11 is combined with the lower water fitting portion 61 so that the water-side covering material 1 of the present application is combined so as not to move upward. For example, as shown in FIG. 3, the fitting portion 11 is combined so as to be inserted between the lower water fitting portion 61 and the roof material 5, and the lower water fitting portion 61 holds the fitting portion 11 from above. It is desirable to be in a state. By adopting such a combination of shapes, it is easy to construct and can withstand a negative pressure.

  The covering surface 12 extends from the fitting portion 11 to the water side and covers the drainage plate 2. It is desirable that the water-side end of the covering surface 12 is at a slightly higher position than the light receiving surface (upper surface) of the lower roof solar photovoltaic panel B. By doing so, it can guide, without accumulating snow, from the waterside covering material 1 of the present application to the light receiving surface of the photovoltaic power generation panel B with the roof in the lower stage. If the water-side end of the covering surface 12 is lower than the light-receiving surface of the lower roofed solar power generation panel B, snow may accumulate there and the effect may not be sufficiently obtained. Conceivable. Further, if the water-side end of the covering surface 12 is significantly higher than the light-receiving surface of the lower roof solar photovoltaic panel B, when the water-side covering material 1 of the present application is attached, Therefore, it is necessary to form an inclination enough for the snow to slide down, so that the waterside covering material 1 itself may be increased in size or the design properties may be impaired.

  The face door portion 13 extends from the covering surface 12 and is folded between the crest portion 21 and the crest portion 21 of the drainage plate 2. As shown in FIG. 3, the water-side edge of the covering surface 12 is bent so as to come into contact with the crest portion 21 of the drainage plate 2 to form the contact surface 14, and is further extended therefrom to extend the drainage plate 2. It is good to form the face door part 13 folded down between the peak part 21 and the peak part 21. FIG.

  In addition, the face door portion 13 is a face door that is easy to attach in a state of being folded downward and prevents a large amount of snow from entering by making the shape to match the cross section between the mountain portions 21 and 21. Can play a role.

  As shown in FIG. 3, the fastening portion 141 is formed on the contact surface 14 that is a portion that contacts the peak portion 21 of the drainage plate 2. However, it is not necessary to form the fastening portion 141 on all the contact surfaces 14 that are in contact with the ridges 21 of the drainage plate 2. The fastening portion 141 may be formed at any location.

  For example, as shown in FIG. 3, the fastening portion 141 may be formed on the contact surface 14 extending from the covering surface 12 to the face door portion 13, or the covering surface 12 may be formed as shown in FIG. 4 described later. You may form in the contact surface 14 formed in the lower surface side.

  Even if the waterside covering material 1 of the present application is placed on the drainage plate 2, the drainage plate 2 may be damaged by setting the portion of the drainage plate 2 that contacts the peak portion 21 to be a planar contact surface 14. Can be difficult to deform. Therefore, by forming the contact surface 14 and forming the fastening portion 141 there, the waterside covering material 1 of the present application can be stably fixed to the drainage plate 2.

  When the waterside covering material 1 is fixed to the peak portion 21 of the drainage plate 2, a drainage gap portion 3 is formed between the waterside end portion of the face door portion 13 and the valley portion 22 of the drainage plate 2. ing. The drain gap 3 can be drained and ventilated and can be of any size as long as the face door 13 can prevent a large amount of snow from entering. Further, the water-side end of the face door 13 may have any shape as long as the effect of the drain gap 3 is not hindered.

  The attachment of the waterside covering material 1 will be described with reference to FIG. First, the lower side of the drainage plate 2 is overlapped and fixed on the upper side of the roof material 5 of the photovoltaic power generation panel B with the lower roof material.

  Next, the waterside covering material 1 of the present application is attached. The fitting part 11 of the waterside covering material 1 is fitted to the water fitting part 61 of the photovoltaic power generation panel B with the roofing material attached on the roof, and the fastening device 4 is driven into the fastening part 141 and the drainage plate Fasten to 2 peak portions 21.

  As described above, when the fastening device 4 is driven and fixed from the surface side of the water-side covering material 1 to the peak portion 21 of the drainage plate 2, the fastening device 4 is used by using a screw with packing as the fastening device 4. It is better not to leak water due to penetration.

  Further, a method of sandwiching a sealer material between the contact surface 14 and the peak portion 21 of the drain plate 2 is also effective. The fastening method may be a method that does not use the fastening tool 4 as long as it can secure the strength enough to withstand snow load and wind load as a result of fastening on the roof.

  Next, the Example which integrated the waterside coating | covering material 1 and the drain plate 2 of this application is demonstrated in FIG. Prior to installation on the roof, the fastening device 4 was driven from the back side of the peak portion 21 of the drainage plate 2 to the fastening portion 141, and the waterside covering material 1 and the drainage plate 2 of the present application were integrated. It is set as the water upper side covering material A with a drain plate. Thus, by setting it as the waterside coating | covering material A with a drain plate, the installation operation on a roof can further be simplified.

  In this case, installation work only fits fitting part 11 in water fitting part 61 of photovoltaic power generation panel B with a roof material attached on the roof, and fixes drainage board 2 on the roof.

  In the embodiment of FIG. 4, since the fastening portion 141 is formed on the lower surface side of the covering surface 12, the portion into which the fastening device 4 is driven is not exposed on the surface. This eliminates the need for a water stop treatment and further saves labor on the roof.

  Next, the shaping | molding of the waterside coating | covering material 1 of this application is demonstrated in FIG.1 and FIG.4. The waterside covering material 1 of the present application may be formed by folded plate processing as shown in FIG. 1 or may be formed by extrusion processing as shown in FIG.

  In addition, the waterside covering material 1 is divided into a plurality of members depending on the size of itself, the shape of the solar power generation panel with roofing material to be combined, the drainage plate, and the like, and is integrated into the waterside covering material 1. It is good also as a shape.
