The roof beam 5 made up of the vertical beam 3 and the horizontal beam 4 conforms to the shape of the outer peripheral end portions of the four sides of the power generation panel 1 and gives sufficient rigidity to the building as the roof beam 5. In other words, the roof beam 5 is configured to have sufficient strength to support the power generation panel 1 so that the power generation panel 1 can be used as a roofing material. In addition, the frame (frame) that covers the cells and wiring parts inside the power generation panel 1, the front cover of the front part of the cells, etc. can withstand sunlight, rain, snow, wind, vibration, etc. It is made of a material with sufficient durability. Furthermore, the frame body and the front cover of the power generation panel 1 have strength and rigidity that can sufficiently withstand these adverse conditions under severe environments such as typhoons and earthquakes. Moreover, it is good that a frame can achieve weight reduction. For example, the frame is lightweight, made of a metal that has been subjected to rust prevention treatment with excellent rigidity, weather resistance, etc., light metal that has been subjected to rust prevention treatment, etc., and is made of synthetic resin, and the front cover is made of tempered glass, It is good that it is made of white plate heat-treated glass. In addition, the power generation panel 1 is provided with a filler, a sealing material, a waterproof sheet, a waterproof jelly, and the like between the front cover and the frame to completely prevent water and the like from entering. That is, the power generation panel 1 has sufficient weather resistance, strength, and rigidity as a roofing material, and can have a long life.

  At the outer peripheral end of the power generation panel 1, a metal strip-shaped (flat plate) pressing plate member 8 a provided on the vertical beam 3, a sheet-like waterproof member 7 a, and a metal flat plate-like plate provided on the upper side of the horizontal beam 4. A pressing plate member 8b and a sheet-like waterproof member 7b are provided. The waterproof members 7a and 7b are provided across the power generation panels 1 arranged in parallel so as to cover the gap between the end faces of the power generation panels 1 arranged in parallel, and prevent water from entering through the gaps. It is a member for. That is, as shown in FIG. 3, the waterproof member 7 a is provided between the power generation panel 1 a and the power generation panel 1 b and between the power generation panel 1 c and the power generation panel 1 d, and prevents water from entering from between them. doing. The waterproof member 7b is provided between the power generation panel 1b and the power generation panel 1c, and between the power generation panel 1d and the power generation panel 1a, and prevents water from entering from this interval. The pressing plate member 8a is a member for pressing the waterproof member 7a from above. The pressing plate member 8b is a member for pressing the waterproof member 7b from above.

  A metal holding plate piece 9, a sheet-like waterproof member 7 c, and the like are provided on top of the joint 6 between the holding plate members 8 b and 8 b and the joint between the holding plate member 8 a and the holding plate member 8 b. ing. The waterproof members 7a to 7c are elastically deformable members (for example, rubber-based sheets, resins (for example), so that watertightness can be exhibited between the power generation panel 1, the pressing plate members 8a and 8b, and the pressing plate piece 9. For example, vinyl chloride etc.) based sheet). Moreover, one or both of the waterproof members 7a to 7c may be in the form of a sticky sheet. The pressing plate members 8 a and 8 b and the pressing plate piece 9 and the like placed on the outer peripheral end of the power generation panel 1 are fastened and fixed to the vertical beam 3 and the horizontal beam 4 by waterproof bolts 26. The waterproof members 7a and 7b exhibit water tightness by being pressed between the presser plate members 8a and 8b and the power generation panel 1 and prevent rainwater from entering between them. The waterproof member 7c exerts water tightness by being pressed between the pressing plate members 8a and 8b and the pressing plate piece 9, and prevents rainwater from entering through the waterproof member 7c. In other words, the waterproof members 7 a and 7 b prevent rainwater and the like from entering the attic 102 from between the power generation panels 1 and 1. The waterproof member 7c prevents rainwater and the like from entering the attic 102 side from the joint 6 or the like of the pressing plate members 8a and 8b.

  As shown in FIG. 5, the threaded portion of the waterproof bolt 26 is screwed into the screw holes 3 b and 4 b formed in the vertical beam 3 and the horizontal beam 4. The screw holes 3b and 4b have a blind hole and become a blind hole. A seal member 26 s is integrally provided on the neck lower seating surface of the head of the waterproof bolt 26. The sealing member 26s prevents rainwater from entering from the neck lower seat surface side of the waterproof bolt 26. Even if a small amount of rainwater invades from the bottom seat surface side of the waterproof bolt 26, it is discharged from the troughs 11a and 11b to the outside of the roof 101 due to the inclination of the trough 11a. . The waterproof bolt may be constituted by a bolt and a seal member (for example, a seal washer) provided separately from the bolt. Moreover, you may waterproof by covering the thread part of a volt | bolt, etc. with a caulking agent (for example, modified silicone). In short, it is sufficient if rainwater can be prevented from entering from the bottom seat surface of the waterproof bolt.

  The waterproof bolt 26 described above is to tighten and fasten a fastening tool (for example, a spanner) from the upper side of the power generation panel 1 to the head of the waterproof bolt 26. However, the waterproof bolt 26A is fastened and tightened from the attic 102 side using a fastening tool (see FIG. 6). The waterproof bolt 26A fastens the power generation panel 1 to the vertical beam 3 (or the horizontal beam 4) by screwing a nut 26n into a threaded portion. On the lower side of the screw shaft portion, a two-side scraping portion 26m, which is an engaged portion, is formed, and the operator applies a fastening tool such as a spanner to the two-side scraping portion 26m and the nut 26n and tightens. Be able to. Further, a seal member 26t is provided between the insertion hole of the vertical beam 3 (or the horizontal beam 4) and the shaft portion of the waterproof bolt 26A. The seal member 26t prevents water from leaking from the troughs 11a and 11b to the attic 102 even if a small amount of rainwater enters from the lower neck surface of the waterproof bolt 26A. The invading rainwater is discharged to the outside of the roof 101 from the troughs 11a and 11b due to the inclination of the trough 11a and the like. The engaged portion may be a slit portion, a cross hole portion, a square shaft portion, a hexagonal shaft portion, or the like.

  The pressing plate members 8 b are arranged side by side so that the end faces in the longitudinal direction are in contact with each other at the joint 6. The pressing plate member 8a is juxtaposed so that the end face in the longitudinal direction is in contact with the side surface in the direction orthogonal to the longitudinal direction of the pressing plate member 8b. The upper surface side in the vicinity of the joint between the presser plate member 8a and the presser plate member 8b covers the joint 6 between the presser plate member 8b and the presser plate member 8b and the joint between the presser plate member 8a and the presser plate member 8b. Further, a sheet-like waterproof member 7c and a pressing plate piece 9 are overlaid and fastened and fixed with waterproof bolts 26 and 26A. By configuring in this way, even if there is precipitation, snowfall, etc. on the upper surface (surface) side of the power generation panel 1 instead of the roof tile, rainwater does not enter the building from the power generation panel 1 side instead of the roof tile. It is the composition. Further, the power generation panel 1 is positioned so that the side surface of the power generation panel 1 is parallel to the troughs 11a and 11b so that the side surfaces of the power generation panel 1 are on top of the troughs 11a and 11b formed on the vertical beams 3 and 4. Therefore, even if rainwater leaks from between the waterproof members 7a, 7b, 7c, etc., it is discharged from the valleys 11a, 11b to the outside of the roof 101 due to the inclination of the valley 11a, etc. It has become so.

  In other words, double waterproofing measures are taken, waterproofing by a waterproofing member and prevention by valley ridges, and rainwater leaks into the building from between the power generation panel 1 instead of the roof tile, the vertical beam 3, and the horizontal beam 4. Does not occur. The presser plate member 8b provided on the upper portion of the cross beam 4 is formed with a drain chamfered portion 10 which is a recess for discharging so that rainwater does not collect on the upper surface side of the power generation panel 1 at a predetermined position. . That is, the rainwater on the upper power generation panel 1 moves to the lower power generation panel 1 via the drain chamfer 10. In this way, rain or the like that has fallen on the top of the power generation panel 1 can easily leak into the building via the roof beam 5, the inclination of the power generation panel 1, the drain chamfered portion 10, the troughs 11a and 11b, and the like. Without discharging, it can be discharged outside the roof 101.

The installation method of the roof structure of this building is demonstrated.
A grid-like roof beam 5 is formed by assembling the vertical beam 3 and the horizontal beam 4 formed to have predetermined dimensions. The grid-like roof beam 5 is fixed to the pillar 25 or the like with a fastening member such as a bolt and a nut and a fastening bracket.

  The power generation panels 1 are sequentially placed on a grid-like roof beam 5 composed of vertical beams 3 and horizontal beams 4, and are fastened and fixed with waterproof bolts 26 or the like. At this time, the power generation panel 1 passes between the roof beams 5 and is lifted from the attic portion 102 side to the upper portion of the roof beam 5 and placed on the roof beam 5. When passing between the roof beams 5, if the power generation panel 1 is directed in the diagonal direction of the grid-like roof beam 5, it can be easily passed. Waterproof members 7 a and 7 b and presser plate members 8 a and 8 b are placed on the upper part of the outer peripheral end of the power generation panel 1, and fastened and fixed with waterproof bolts 26. Further, in the vicinity of the joint between the pressing plate members 8 a and 8 b, the waterproof member 7 c and the pressing plate piece 9 are placed and fastened and fixed with the waterproof bolts 26. This work can be performed by an operator reaching out from the attic 102 side. By such a procedure, most of the power generation panels 1 can be placed and fastened and fixed.

  The power generation panels 1 in the last row are fastened and fixed from the attic 102 side by waterproof bolts 26A. That is, after the power generation panel 1 is placed on the roof beam 5, the waterproof members 7a and 7b and the pressing plate members 8a and 8b are placed on the temporary table provided outside the building, and the fastening bolt 26A is inserted. . In the vicinity of the joint between the pressing plate members 8a and 8b, the waterproof member 7c and the pressing plate piece 9 are placed, and the waterproof bolt 26A is inserted. Thereafter, the nut 26n is screwed into the waterproof bolt 26A from the attic 102 side and fastened and fixed. This fastening and fixing work can be easily performed by applying a fastening tool to the two-side shaving portion 26m and the nut 26n. After installing the power generation panel 1 on the roof beam 5, wiring work such as connection of the connection cable from the attic 102 to the power generation panel 1 and connection of the connection cable in the distribution box is performed. The work from the attic 102 side is very easy and highly safe. In addition, inspection and maintenance of the power generation panel 1 can be performed from the attic 102, and the work is very easy. The waterproof bolt 26A, the nut 26n, and the like constitute a fastening member.

  Thus, the operator does not have to work on the top of an inclined roof beam, etc., and is very safe, and the workability and productivity such as installation, inspection, and maintenance of the power generation panel 1 are very high. It can improve and shorten the enforcement period for power generation panel installation. Moreover, the construction cost for installing the power generation panel can be reduced.
