Description

  The present invention relates to a solar device fixing structure for installing and fixing solar devices such as a solar battery panel and a solar water heater on a flat roof, outdoors such as on the ground.

  As a fixing structure for installing a solar cell panel on a flat roof, the solar cell panel is generally fixed to a supporting frame installed on the flat roof using bolts and nuts. Specifically, a structure is adopted in which a bolt is passed through an attachment hole formed in the outer frame of the solar cell panel and an attachment hole formed in the support frame and fastened with a nut. However, in the case of this fixing structure, if there is a shift in the positions of both mounting holes due to a manufacturing error, there is a problem that the position adjustment is required and the workability of the fixing work with bolts and nuts is poor.

  On the other hand, as another fixing structure, a structure is also used in which a solar cell panel is sandwiched and fixed on a support frame using a dedicated fixing bracket. Patent Document 1 below discloses a similar structure in which a solar cell panel is fixed to a slate thatched roof instead of a flat roof using a dedicated fixing bracket.

  However, in the case of a fixing structure that uses a fixing bracket, the solar panel is sandwiched between the fixing brackets on the support frame, so a space is required to fix the fixing bracket with the solar panel sandwiched on the support frame. There is a problem that the space efficiency of the solar panel installation is lowered. In other words, in order to sandwich the solar cell panel on the support frame, it is necessary to fix the fixing bracket on the support frame with bolts and nuts in a state where the solar cell panel is sandwiched on the support frame. At that time, a space for fastening bolts and nuts is required on the fixing bracket adjacent to the solar cell panel. As a result, the space occupied by the fixture on the support frame increases, and a large space is required to install the required number of solar cell panels. Or the number of solar cell panels that can be installed in a limited space is reduced.

  In view of such problems, an object of the present invention is to fix a solar device such as a solar battery panel on a support frame installed outdoors using a fixing bracket, and a bolt on the fixing bracket. -By eliminating the need for nut fastening work, the size of the fixture is reduced by the space required for bolt and nut fastening work, and the space efficiency of solar equipment installation is improved.

A solar device fixing structure for fixing and fixing the solar device on the support frame, wherein one of the combination of bolts and nuts is non-rotatably held on the fixing bracket, and the bottom of the support frame The other of the bolt and nut combination is fastened to the one in a state where a fixing bracket is sandwiched with a solar device on a support frame.

  In the first invention, the fixing bracket may be an end fixing bracket that fixes a solar device at an end where no adjacent solar device exists, or may be an intermediate fixing bracket that fixes solar devices adjacent to each other at the same time. Various structures can be adopted as the holding structure that holds one of the bolts and nuts in a non-rotatable manner on the fixture.

  According to a second invention, in the first invention, the fixing bracket is installed between adjacent solar devices among a plurality of solar devices fixed on the support frame, and ends of the solar devices adjacent to each other. Intermediate fixing metal fittings sandwiching the part, between the pair of flange parts engaged with the end parts of both solar devices, a wall surface part is formed so as to hold the head of the bolt unrotatable, The wall portion is in contact with the head of the bolt so as to prevent rotation of the bolt head when the nut is fastened.

  2nd invention WHEREIN: The wall surface part of a fixing metal fitting may protrude and protrude in the side spaced apart from a support frame between a pair of flange parts.

  According to a third aspect of the present invention, in the second aspect of the present invention, the support frame is configured such that the wall surface portion of the fixing bracket forms a space for holding the head of the bolt between the pair of flange portions of the fixing bracket. The bent portion is formed by a bent portion bent to the side, and the bent portion is sandwiched between the end portions of both solar devices, and is prevented by the bent portion so as to prevent rotation of the bolt head when the nut is fastened. A pair of the wall surfaces formed opposite to each other is sized to sandwich the head of the bolt.

An end fixing bracket 30 is fixed on the main frame 12 corresponding to the front end portion of the foremost solar cell panel 20, and the front end portion of the solar cell panel 20 is sandwiched by the flange portion 31 of the end fixing bracket 30. . Moreover, the intermediate | middle fixing metal fitting 40 is fixed on the main frame 12 corresponding to the edge part of the solar cell panel 20 located between adjacent solar cell panels 20, and each edge part of the solar cell panel 20 is the intermediate | middle fixing metal fitting 40. It is clamped by the flange part 41 of.

  The end fixing bracket 30 is fixed to the main frame 12 by passing the bolt 51 through the through hole 33 of the end fixing bracket 30 and a through hole (not shown) on the main frame 12 and fastening a nut 52 to the bolt 51. Is done by that. At this time, the head of the bolt 51 is brought into contact with the wall surface portion 32 a formed by the bent portion 32 of the end fixing bracket 30, and cannot be rotated with respect to the end fixing bracket 30. For this reason, when the female threaded portion of the nut 52 is screwed into the male threaded portion of the bolt 51 and fastened, the bolt 51 is prevented from being rotated. Therefore, it is not necessary to hold the head portion of the bolt 51 with a tool so that the bolt 51 does not rotate when the nut 52 is fastened to the bolt 51, and the head portion of the bolt 51 and the bent portion of the end fixing bracket 30. Therefore, it is possible to eliminate the need to provide a space for inserting a tool between the two. The flange portion 34 of the end fixing bracket 30 is in contact with the front end edge of the main frame 12 so that the end fixing bracket 30 does not rotate relative to the main frame 12.

  In addition, the intermediate fixing bracket 40 is fixed to the main frame 12 by passing the bolt 61 through the through hole 43 of the intermediate fixing bracket 40 and the through hole (not shown) of the main frame 12, and fastening the nut 62 to the bolt 61.

Therefore, it is not necessary to hold the head of the bolt 61 with a tool so that the bolt 61 does not rotate when the nut 62 is fastened to the bolt 61, and the head of the bolt 61 and the bent portion 42 of the intermediate fixing bracket 40 are eliminated. It is possible to eliminate the need to provide a space for inserting a tool between the two.

  Thus, each of the bolts 51 and 61, which is one of the combinations of the bolts 51 and 61 and the nuts 52 and 62, is held on the end fixing bracket 30 or the intermediate fixing bracket 40 so as not to rotate. Each nut 52, 62, which is the other of the combination of 61 and nuts 52, 62, is fastened to each bolt 51, 61 across the end fixing bracket 30 or the intermediate fixing bracket 40 and the main frame 12. Therefore, the space on the end fixing bracket 30 and the intermediate fixing bracket 40 at the heads of the bolts 51 and 61 is small, and the space occupied by the end fixing bracket 30 and the intermediate fixing bracket 40 on the main frame 12 is reduced. be able to. Therefore, the space efficiency of the solar cell panel 20 installation can be improved. Moreover, since the fastening operation | work with respect to each volt | bolt 51 and 61 of each nut 52 and 62 can be performed only from the lower side of the solar cell panel 20, it is the sun for the fastening operation | work with respect to each volt | bolt 51 and 61 of each nut 52 and 62. The work performed on the battery panel 20 can be eliminated, and the risk of damaging the solar battery panel 20 during the fastening work can be eliminated. Moreover, since the lower side of the main frame 12 is an open space, the workability of the fastening operation of the nuts 52 and 62 with respect to the bolts 51 and 61 can be improved. Further, when the fastening work of the nuts 52 and 62 to the bolts 51 and 61 is performed on the upper side of the end fixing bracket 30 or the intermediate fixing bracket 40, the bolts 51 and 61 must be fixed on the main frame 12. It is necessary to prepare nuts separately from the nuts 52 and 62 and perform the fixing. However, as in the present embodiment, the fastening operation of the nuts 52 and 62 to the bolts 51 and 61 is performed on the main frame 12. When performing from the bottom, there is also an advantage that it is not necessary to prepare an extra nut.

  FIGS. 9-11 has shown the mode of the operation | work which fixes the solar cell panel 20 on the two main frames 12. FIG. First, FIG. 9 shows a state in which the frontmost solar cell panel 20 is fixed on the main frame 12. Here, with the end fixing bracket 30 temporarily fixed at the foremost end position of each main frame 12, the solar cell panel 20 is directed toward the bent portion 32 of each end fixing bracket 30 as indicated by a white arrow. Moving on the main frame 12, the front end portion of the solar cell panel 20 is brought into contact with the bent portion 32 of each end fixing bracket 30. In that state, nuts 52 are fastened to the bolts 51, the two front end portions of the solar cell panel 20 are sandwiched by the flange portions 31 of each end fixing bracket 30, and the solar cell panel 20 is Fix on the main frame 12. Since the solar cell panel 20 is sandwiched between the flange portions 31 of the end fixing bracket 30 in this way, the vertical dimension of the end fixing bracket 30 is determined according to the thickness of the solar cell panel 20.

  Next, FIG. 10 shows a state where the rear solar cell panel 20 is fixed adjacent to the frontmost solar cell panel 20 fixed on the main frame 12 as described above. Here, the solar cell panel 20 on the rear side is attached to each intermediate fixture 40 in a state where the intermediate fixture 40 is temporarily fixed on each main frame 12 corresponding to the rear end position of the solar cell panel 20 on the foremost end. It moves on the main frame 12 toward the bent part 42 as shown by the white arrow, and the front end part of the rear solar cell panel 20 is brought into contact with the bent part 42 of each intermediate fixing bracket 40. In that state, the nut 62 is fastened to each bolt 61, and the two rear and front end portions of the two solar cell panels 20 are sandwiched between the flange portions 41 of the intermediate fixing bracket 40, Two solar cell panels 20 are fixed on the two main frames 12. At this time, due to manufacturing variations, the position of the through hole 43 of the intermediate fixing bracket 40 through which the bolt 61 passes and the position of the through hole (not shown) on the main frame 12 may be shifted in the front-rear direction. Even in such a case, it is desirable that the through hole on the main frame 12 is formed long in the front-rear direction so that the bolt 61 can penetrate both through holes. Since the solar cell panel 20 is sandwiched between the flange portions 41 of the intermediate fixing bracket 40 in this way, the vertical dimension of the bolt 61 is determined according to the thickness of the solar cell panel 20.

  Thereafter, similarly, the solar cell panels 20 positioned sequentially on the rear side are fixed onto the two main frames 12 by two intermediate fixing brackets 40. The rearmost solar cell panel 20 is the frontmost solar cell panel. The rear end of the solar cell panel 20 at the rearmost end is fixed on the main frame 12 by the end fixing bracket 30 in the same manner as the front end of 20 is fixed on the main frame 12 by the end fixing bracket 30. FIG. 11 shows a state in which the four solar cell panels 20 are fixed on the two main frames 12 in this way. At this time, since the space around each bolt 51, 61 in the end fixing bracket 30 and the intermediate fixing bracket 40 is small, the space in the front-rear direction for installing four solar cell panels 20 can be reduced. . Therefore, many solar cell panels 20 can be installed in a limited space on the land roof. 1-3 and FIG. 11, although the case where the four solar cell panels 20 were arranged in the front-back direction was demonstrated, it is also possible as needed to arrange the solar cell panel 20 of the more number of sheets in the front-back direction. In this case, the space efficiency improvement effect due to the small space on the main frame 12 of the end fixture 30 and the intermediate fixture 40 is further increased.
