Description

  The present invention relates to a solar cell module mounting structure used when a solar power generation device is installed on a roof surface of a building.

Since solar power generation has a low environmental impact and can conserve resources, development is progressing as a countermeasure for global issues such as environmental pollution caused by exhaust gas containing CO ₂ (carbon dioxide), which is the basis of global warming, and depletion of energy resources. It is also widely used in ordinary homes, including commercial buildings and public facilities.

  By the way, roof materials such as tiles are designed and manufactured without considering the installation of objects on them. Therefore, when installing a solar cell module on the roof material in a detached house, etc., it has a complicated structure, including various conditions such as the roof surface having various slopes and a complete rain finish. Solar cell modules are supported and workability tends to be inferior. Thus, improvements have been made repeatedly, and various mounting structures have been proposed (see, for example, Patent Document 1).

  As one example, in the mounting structure shown in FIGS. 9 and 10, first, as shown in FIG. 9 (A), a through hole d is drilled in the roof material a from above using an electric drill b, and then FIG. As shown in FIG. 9B, in order to maintain waterproofness, the through hole d is filled with a watertight material n such as butyl rubber, and is inserted from above as shown in FIG. The vertical rail g is fixed with a screw e1.

  Further, in the mounting structure shown in FIG. 11, a part (a1) of the roof material a is once removed, and the base plywood i and the space plywood j penetrate the roof baseboard f into the rafter k through the exposed roof baseboard f. It is fixed by the driven screw e2. The Z-shaped metal fitting m in which the substrate m1, the vertical piece m2 rising from the edge of the eaves side of the substrate m1, and the upper piece m3 extending from the upper end of the vertical piece m2 toward the eaves side are bent together. The ridge side of the substrate m1 is fixed on the space plywood j with the screw e3, and the vertical rail g is attached to the upper piece m3. Then, the removed roof material a1 is returned to its original position, and the attachment portion is rained.

JP 2004-162487 A

  However, in the former mounting structure shown in FIGS. 9 and 10, since the load of the solar cell module h is applied to the roof material a through the vertical rail g placed on the roof material a, it is under a strong wind such as a typhoon. When a large stress is generated, the roof material a is likely to be cracked or chipped, the support of the solar cell module h is unstable, and there is a risk of rain leakage. In particular, when installing a photovoltaic power generation facility by renovation on the roof of an existing building, the roof material a is often reduced in strength due to deterioration over time, and there is a high possibility of impairing the rain performance.

  In addition, as shown in FIG. 9C, this construction method inserts the screw e1 into the watertight material n filled in the drilled through hole d and drives it into the roof base plate f to attach the vertical rail g. The water-stopping state due to the water-tight material n later cannot be visually confirmed, and the water-tight material n may be detached from the through-hole d when the screw e1 is inserted, and the reliability of the rain performance is low.

  Furthermore, since the diameter of the through hole d drilled in the roof material a is slightly larger than the screw e1, the state of the thickness, material, degree of deterioration, etc. of the roof base plate f is visually observed through the through hole d. It cannot be confirmed. Accordingly, in the renovation, the fixing strength of the screw e1 cannot be determined. Therefore, it is necessary to fix the screw e1 in a large amount on the basis of the prediction.

  In the latter mounting structure shown in FIG. 11, the vertical rail g is attached to the roof base plate f via the Z-shaped metal fitting m that can extend from the overlapping portion of the roof material a adjacent in the gradient direction. Therefore, the vertical rail g is supported by the upper piece m3 at a position greatly deviated downward from the position fixed to the roof base plate f by the screw e3 on the ridge side of the substrate m1. Therefore, when positive and negative dynamic pressure due to wind load acts on the solar cell module h, the Z-shaped metal fitting m is deformed by the action of bending force, and the support of the solar cell module h becomes unstable.

  In addition, as a problem of the embodiment of the present invention, when the screw e2 is driven and fixed to the rafter k, the roofing sheet may be laid and the position of the rafter k is unknown from the roof base plate f. The rafter tends to be removed, and the mounting strength is insufficient.

  The present invention is based on the fact that the fixture is inserted into a notch formed in the roof material and fixed in a state of being placed on the roof base plate, and the support structure is simple and the solar cell module is stabilized. Therefore, it is an object to provide a solar cell module mounting structure that can be mounted and has excellent workability.

  In the invention which concerns on Claim 4, the said fixture was comprised with the fixing metal fitting which has the fixing bolt which faces upwards for attaching a support body, and provided the coating | coated cover which covers the said notch part and the said fixing metal fitting, and is watertight. Further, in the invention according to claim 5, the fixing bracket includes a U-shaped opening that opens downward, and a mounting flange that extends and bends outward from the lower ends of the opposing vertical pieces of the U-shaped body. The covering cover includes a cover body and a cap disposed on the cover body. The cover body includes a shell portion that surrounds the fixing bracket, and a peripheral portion of the shell portion. And the cap is fitted to the shell portion of the cover body from above.

  In the invention which concerns on Claim 6, the said fixture is fixed to a roof baseplate using an expansion sticker, and the said expansion sticker is penetrated by the attachment hole drilled in a roof baseplate. And a retaining portion that is formed at the lower end of the insertion portion and is inserted into the mounting hole from above and that expands below the roof base plate and engages the roof base plate. The fixture is fixed to the roof base plate using the engagement between the portion and the roof base plate.

  In the invention according to claim 1, since the fixture is inserted into the notch formed in the roof material and fixed to the roof base, the load of the solar cell module is supported by the roof base almost directly through the fixture. . As a result, the support structure is simplified, the mounting strength of the solar cell module is stabilized, the support structure is reliably supported even under strong winds such as typhoons, and the workability is excellent. In addition, since the load of the solar cell module is not applied to the roofing material, damage to the roofing material is prevented, and there is no risk of rain leakage even if the roofing material deteriorates over time when it is attached to an existing building by renovation. . Furthermore, in the reform, since the deterioration state of the roof base plate can be visually confirmed through the notch, it is possible to perform construction corresponding to the situation and improve reliability.

  As in the case of the invention according to claim 2, when fixing to the roof base plate using the separated fixing part, the installation workability is excellent, and the installation height of the solar cell module can be increased by replacing the cylindrical part having a different height dimension. The height can be adjusted arbitrarily. Further, when the space between the cylindrical portion and the inner edge of the notch portion is watertightly sealed as in the invention according to claim 3, the sealing work can be performed while visually checking from above the roofing material. Can be constructed and workability can be improved.

  When configured as in the invention according to claim 4, the support body can be firmly supported by using the fixing bolt and the rain cover with high accuracy can be configured by the covering cover. In the invention according to claim 5, the fixing bracket is attached. Because it is strongly fixed to the roof base plate using a flange, the mounting state of the solar cell module is stable, and the cover body has a collar portion extending along the roof surface, so that it can be stably mounted on the roof surface. Since the rain finish is good and the cap is fitted to the shell portion of the cover body, the rain finish accuracy is further improved.

  Further, as in the invention according to claim 6, when the fixture is fixed to the roof base plate using the spread fixing tool, even if the roof base plate has deteriorated over time in the case of renovation, it is stable without being damaged. Since the attachment strength can be obtained, and the fixture can be fixed regardless of the position of the rafter, the workability is good.

  The roofing material 3 is disposed on a roofing sheet 27 laid on the roof base plate 2 for waterproofing the roof, and each roofing material 3 has a substantially rectangular flat plate shape from the eaves to the ridge direction. On the other hand, the roof base plate 2 is attached to the roof base plate 2 without a gap while overlapping the lower end portion of the roof material 3 on the ridge side with the upper end portion of the roof material 3 on the eave side. The roofing material 3 may employ various types such as a press cement tile, a glazed cement tile, a concrete tile, an smoldering tile, and a metal tile.

  As shown in FIG. 3, a notch 6 is formed in the roof material 3. The notches 6 in this embodiment are circular, and are spaced at a predetermined assigned pitch based on the required support strength of the solar cell module M. The diameter is, for example, about 20 to 80 mm, and in this embodiment, the size is 40 mm, and can be formed by cutting using a hole saw attached to an electric drill. The state of the thickness, material, and deterioration state of the roof base plate 2 is visually confirmed from the top of the roofing material 3 through the notch 6 formed in this way, and the solar cell module M is appropriately selected according to the state. Selection, change, and reinforcement of the fixing means are appropriately performed, and as a result, the reliability of the solar cell module mounting can be improved.
