JP 2012-149441 A

  When many solar cell panels are installed on the corrugated slate roof, the solar cell panels cannot be installed beyond the length of the vertical beam. For this reason, a gap is formed between other modules similar to the module of the solar cell panel fixed by one vertical rail, and the installable area of the solar cell panel is reduced on the roof. Because the position where the bracket can be fixed on the corrugated slate roof is limited to the position where the purlin exists, it corresponds to the gap between the ends of the two vertical bars connected in the vertical direction between the vertical brackets Thus, an area where the solar cell panel cannot be installed is formed.

  In view of such a problem, an object of the present invention is to provide two vertical beams connected in the vertical direction by metal fittings in a support device that installs an installation object on a roof such as a solar cell panel on a roof via metal fittings and vertical rails. By connecting the ends of each other, a gap corresponding to the gap between the metal fittings arranged in the vertical direction is not formed between the installation objects on the roof fixed by the two vertical bars connected in the vertical direction. It is in suppressing that the installation possible area of an installation thing on a roof reduces on a roof.

  A first invention is a roof support device for installing an installation on a roof on a corrugated roof having a shape in which a plurality of mountains are arranged in a lateral direction. A plurality of brackets fixed to the main building of the cabin set at predetermined intervals in each horizontal direction, and the vertical brackets that are fixed over the plurality of brackets arranged in the vertical direction and support the installation on the roof A metal fitting for fixing at least an end of the vertical beam among the metal fittings is formed so that two vertical beams continuous in the vertical direction can be fixed together.

  According to the first aspect of the present invention, the metal fitting for fixing at least the end of the vertical beam among the metal fittings is capable of fixing two vertical beams connected in the vertical direction together. Vertical bars will be connected in the vertical direction. Therefore, the installation on the roof is the same as that fixed to the vertical beam elongated in the vertical direction, and is installed without leaving a gap at the end of the vertical beam. Therefore, it is possible to suppress a reduction in the installable area of the installation object on the roof.

  Examples of corrugated roofs include corrugated slate roofs and folded plate roofs. Moreover, there exist a solar cell panel, a solar water heater, etc. as an installation on a roof. Furthermore, the metal fitting may be fixed across adjacent mountains, or may be fixed to one mountain. Furthermore, the metal fittings that can fix the two vertical bars may have a side-by-side structure in which the two vertical bars are displaced from each other in the horizontal direction and fixed side by side in the horizontal direction. A vertical connection structure may be used in which the crosspieces are fixed so as to be connected to each other in the vertical direction without being displaced in the horizontal direction. The horizontal structure metal fittings are formed with a large horizontal dimension, and the vertical connection metal fittings are formed with a large vertical dimension.

  According to a second invention, in the first invention, the metal fitting for fixing at least the end of the vertical rail among the metal fittings is configured to straddle three adjacent peaks of the corrugated roof, and is continuous in the vertical direction. The vertical bars of the book are fixed to the metal fittings in parallel with each other on two valleys between the three peaks.

  According to the second invention, since the metal fitting is configured to straddle the three adjacent peaks of the corrugated roof, the load from the installation on the roof can be distributed to the three peaks, and two It is possible to secure a sufficient width for arranging and fixing the vertical bars in the horizontal direction.

  A third invention is the above-mentioned second invention, wherein the metal fitting for fixing at least the end of the vertical beam among the metal fittings is a combination of two metal fittings configured to straddle two adjacent peaks of the corrugated roof It is constructed so as to straddle three mountains, and the ends of the two metal fittings are stacked one above the other so as to be fixed to the central mountain of the three mountains, and arranged on the upper side in the overlapping part A height adjustment metal fitting is provided below the other end of the metal fitting so as to suppress the inclination of one metal fitting in the lateral direction.

  According to the third aspect of the invention, it is possible to configure a bracket that straddles three peaks using a bracket that straddles two peaks, and the required shape depends on whether one type of bracket is used in combination or used alone. It is possible to correspond to the brackets for fixing the end of the vertical beam and for fixing the intermediate part of the vertical beam.

  According to a fourth aspect of the present invention, in the second or third aspect of the invention, the metal fitting is positioned between a mountain abutment portion that abuts each other on tops of adjacent ridges of the corrugated roof and a mountain abutment portion adjacent to each other A vertical beam support portion for supporting the vertical beam, and the mountain contact portion is formed in a mountain shape so as to contact both hem sides of the top of the corrugated roof, and the vertical beam support portion Is characterized in that a flat surface portion is formed at a position higher than the top of the mountain-shaped mountain contact portion.

  According to the fourth aspect of the present invention, the mountain contact portions of the metal fittings are formed in a mountain shape so as to contact the both hem sides of the top of the roof material, so that the entire mountain to which the metal fittings are attached is well balanced. The load applied to the metal fitting can be borne. Therefore, it can be used even when the strength of the roofing material is weak. In addition, since the vertical beam support portion of the metal fitting has a flat surface portion formed at a position higher than the top of the mountain-shaped mountain contact portion, it does not interfere with the mountain contact portion on the flat surface portion of the vertical beam support portion. Vertical rails and rooftop installations can be installed. Thus, since the metal fitting is composed of a mountain contact portion formed in a mountain shape and a vertical beam support portion formed between two mountain contact portions and formed at a position higher than them, two pieces are provided. The mountain contact portions of the metal fittings can be stacked one above the other. Therefore, it is possible to configure one metal fitting that fixes the end portion of the vertical beam only by overlapping and combining the two metal fitting end portions.

  According to a fifth aspect of the present invention, in the fourth aspect of the present invention, the vertical beam support portion is formed with a through hole into which the vertical beam fixing bolt is inserted in the flat surface portion, and the through hole is in the direction of the mountain contact portion. A flange portion is formed on the end edge portion along the longitudinal direction of the through hole, and a flange portion is formed by extending the end edge portion to the roof side. The extension length of the flange portion to the roof side is: The rotation stop corner portion between the head portion and the screw portion of the vertical beam fixing bolt inserted into the through hole has a length that does not protrude on the flat surface portion of the vertical beam support portion. .

  According to the fifth invention, since the through hole is formed in the flat surface portion of the vertical beam support portion and the through hole is formed long in the direction of the mountain contact portion, the vertical beam is fixed to the vertical beam support portion. The fixing position of the vertical beam fixing bolt can be adjusted by moving within the through hole. In addition, since the flange is formed in the through hole, the rotation stopper corner portion of the vertical beam fixing bolt inserted into the through hole is accommodated within the extension dimension of the flange portion, and on the flat surface portion of the vertical beam support portion. It is possible to prevent the rotation stop corner from affecting the vertical rail when the vertical rail is fixed on the flat surface portion.

  And a flange part functions as a reinforcement rib with respect to a flat surface part, and can raise the bending strength with respect to the load of the direction perpendicular | vertical to the flat surface part added by the installation thing on a roof via a vertical rail. As a result, the vertical dimension of the metal fitting can be reduced. The metal fittings are fixed to the main building of the roof with sandwiching the roofing material, but the roofing material is also fixed to the roofing by fastening the roofing material fixing bolts to the main building. Since both of them interfere with each other at the portion to be fixed, it is generally performed to remove the roof material fixing bolt at the portion where the metal fitting is fixed. However, according to the fifth aspect, since the metal fitting can be made small, the interference can be avoided, and the work for removing the roof material fixing bolt can be made unnecessary.

  6, 7 and 16 show a first embodiment of the present invention. 1st Embodiment is the example which applied this invention to the support apparatus for roofs for installing the solar cell panel 5 (equivalent to the installation thing on a roof of this invention) on the corrugated slate roof 6 which is a corrugated roof. Show. In the first embodiment, a combination of two metal fittings 10 is used as the metal fitting 1 for fixing the end portions of the two vertical bars 3 and 3 that are continuous in the vertical direction on the corrugated slate roof 6. The individual metal fittings 10 are commonly used as the intermediate part fixing metal fittings of the vertical bars 3.

  1-3 show the metal fitting 10. The metal fitting 10 is attached over the top of the adjacent mountain of the corrugated slate roof 6, and is configured to fix the vertical rail 3 on the valley between the mountains. Specifically, the metal fitting 10 includes two crest abutting portions 10a that abut each of the tops of the crests, and a vertical beam supporting portion 10b that is positioned between the crest abutting portions 10a and supports the vertical beam 3. And have. The mountain contact portion 10 a is formed in a mountain shape having an inner inclined portion 13 and an outer inclined portion 14 so as to contact both hem sides of the top of the peak of the corrugated slate roof 6. On the other hand, the vertical beam support portion 10b has a leg portion extending from each end of the inner inclined portions 13 so that the flat surface portion 11 is formed at a position higher than the flat surface portion 15 forming the top of the mountain-shaped mountain contact portion 10a. 12 are raised, and a flat surface portion 11 is formed between the compatible legs 12.

  The vertical beam support portion 10b is formed with a through hole 11a through which the vertical beam fixing bolt 18 (see FIGS. 6 and 7) is inserted into the flat surface portion 11, and the through hole 11a is long in the direction of the mountain contact portion 10a. Is formed. A flange portion 16 is formed at the end edge portion along the longitudinal direction of the through hole 11a. The flange portion 16 is extended to the corrugated slate roof 6 side. The extension length is such that the rotation stop corner portion 18a between the head portion and the screw portion of the vertical beam fixing bolt 18 inserted into the through hole 11a does not protrude on the flat surface portion 11 of the vertical beam support portion 10b. It is said.

  When two metal fittings 10 are combined to form the metal fitting 1 for fixing the ends of two vertical bars 3 and 3 that run in the vertical direction, the ends of the two metal fittings 10 and 10 are used as shown in FIGS. The mountain contact portions 10 a which are the portions are stacked one above the other so that the overlapped portion is fixed to the center mountain of the three peaks of the corrugated slate roof 6. The fixing here is performed by inserting the bolts 17 into the through holes 15 a of the flat surface portions 15 of the respective metal fittings 10, passing through the tops of the peaks of the corrugated slate roof 6, and fastening them to the main building 7. A height adjusting bracket 19 (see FIGS. 4 and 5) is provided on the lower side of the mountain contact portion 10a forming the other end portion of the one metal fitting 10 disposed on the upper side in the overlapping portion. The inclination in the horizontal direction is suppressed. At this time, the height adjusting fitting 19 also has the bolts 17 inserted through the through holes 19a. In the metal fitting 1 configured by combining the two metal fittings 10 and 10 in this way, the height of the one metal fitting 10 at the corrugated slate roof 6 is higher than that of the other metal fitting 10, and thus each flat surface portion 11. Thus, the solar cell panel 5 fixed on each flat surface portion 11 via each vertical rail 3 cannot be fixed on the surface having the same height. Therefore, in the first embodiment, as shown in FIG. 7, the vertical rail 3 is fixed on the flat surface portion 11 of the metal fitting 10 having a low height via the metal fitting 20 for height adjustment serving as a spacer. However, the height adjusting bracket 20 may be provided on the vertical rail 3.

  In the first embodiment, as shown in FIG. 16, the metal fitting 1 that fixes the ends of the two vertical bars 3, 3 is parallel to each other by shifting the two vertical bars 3, 3 connected in the vertical direction in the horizontal direction. It can be fixed together so that Therefore, a plurality of vertical bars 3 and 3 are connected in the vertical direction via the metal fitting 1, and the solar cell panel 5 is fixed to the vertical bars 3 that are elongated in the vertical direction without joints. It will be the same. Therefore, the solar cell panel 5 is installed without leaving a gap at the end of the vertical beam 3, and it is possible to suppress a reduction in the installable area of the solar cell panel 5 on the roof. Here, each purlin 7 is schematically shown by one line.

  As shown in FIG. 15, the reinforcing area that can be supported by the vertical rail 3 in the solar cell panel 5 is limited to the range of 5a and 5b. The reinforcing areas 5 a and 5 b are determined by the structure of the solar cell panel 5. Therefore, it is necessary to determine the positions of the metal fittings 10 and 1 and the vertical rail 3 fixed on the corrugated slate roof 6 so as to be within the reinforcing areas 5 a and 5 b of the solar cell panel 5.

  In FIG. 17, as compared with FIG. 16, an installed state of the solar cell panel 5 according to the conventional technique when the two vertical bars 3 and 3 are connected in the vertical direction is shown. As is clear from this, when the vertical beam 3 is fixed using the conventional metal fitting 100 and the solar cell panel 5 is installed by the vertical beam 3, the vertical beam 3 is formed at the ends of the two vertical beams 3 and 3. The solar cell panel 5 cannot be installed in this portion.

  In addition, since the metal fitting 1 is configured to straddle three adjacent peaks of the corrugated slate roof 6, the load from the solar cell panel 5 can be distributed to the three peaks, and two vertical It is possible to ensure a sufficient lateral width for fixing the crosspieces 3 and 3 in the horizontal direction. Moreover, it is possible to configure the metal fitting 1 that straddles three mountains using the metal fitting 10 that is configured to straddle two mountains, depending on whether one type of metal fitting 10 is used in combination or used alone. It is possible to correspond to the brackets 1 and 10 for fixing the end of the vertical beam 3 having different shapes and fixing the intermediate part of the vertical beam.

  The mountain contact portion 10a of the metal fitting 10 is formed in a mountain shape so as to come into contact with both hems on the top of the peak of the corrugated slate roof 6 by the inner inclined portion 13 and the outer inclined portion 14. The load applied to the metal fitting 10 can be borne in a well-balanced manner over the entire mountain to which the 10 is attached. Therefore, it can be used even when the strength of the corrugated slate roof 6 is weak. Further, the vertical beam support portion 10b of the metal fitting 10 has the flat surface portion 11 formed at a position higher than the top of the mountain-shaped mountain contact portion 10a, so that the vertical beam support portion does not interfere with the mountain contact portion 10a. The vertical beam 3 and the solar cell panel 5 can be installed on the flat surface portion 11 of 10b. Thus, the metal fitting 10 is composed of a mountain contact portion 10a formed in a mountain shape and a vertical beam support portion 10b formed between two mountain contact portions 10a and formed at a position higher than them. Therefore, the mountain contact portions 10a of the two metal fittings 10 can be stacked one above the other. Therefore, one metal fitting 1 can be formed only by overlapping and combining the ends of the two metal fittings 10.

  Further, a through hole 11a is formed in the flat surface portion 11 of the vertical beam support portion 10b, and the through hole 11a is formed long in the direction of the mountain contact portion 10a. Therefore, the vertical beam 3 is fixed to the vertical beam support portion 10b. The fixing position of the vertical rail fixing bolt 18 can be adjusted by moving the through hole 11a. Further, since the flange portion 16 is formed in the through hole 11a, the rotation stop corner portion 18a of the vertical beam fixing bolt 18 inserted into the through hole 11a is accommodated within the extension dimension of the flange portion 16, and the vertical beam. It is possible not to protrude on the flat surface portion 11 of the support portion 10b, and it is possible to prevent the rotation stop corner portion 18a from affecting when the vertical rail 3 is fixed on the flat surface portion 11.

  And the flange part 16 functions as a reinforcement rib with respect to the flat surface part 11, and can raise the bending strength with respect to the load of the direction perpendicular | vertical to the flat surface part 11 applied by the solar cell panel 5 via the vertical rail 3. FIG. As a result, the vertical dimension of the metal fitting 10 can be reduced. As shown in FIG. 8, the metal fitting 10 is fixed to the main building 7 of the shed with the corrugated slate roof 6 interposed therebetween, and the fixing of the corrugated slate roof 6 to the shed is also between the main building 7 and the roof material fixing bolt. 63 is fastened, and both interfere with each other at a portion where both are fixed at the same time. Therefore, the roof material fixing bolt 63 is generally removed at the portion where the metal fitting 10 is fixed. Is called. However, according to 1st Embodiment, since the metal fitting 10 can be made small, the said interference can be avoided and the removal operation | work of the roof material fixing volt | bolt 63 can be made unnecessary.

FIG. 14 shows a state in which a strength test similar to that in the case of FIG. 13 was performed using a flat-plate-shaped test metal fitting 200 having the same material and the same plate thickness as the metal fitting 10. In the strength test of FIG. 13, the struts 300 are inserted into the through holes 15 a formed in the flat surface portions 15 of the mountain contact portions 10 a on both sides of the metal fitting 10, and both ends of the metal fitting 10 are supported on a base (not shown). Is done. Then, the pulling bolt 400 is inserted into the through hole 11a of the vertical beam support portion 10b, and a predetermined force (corresponding to the wind pressure received when the metal fitting 10 fixes the solar cell panel 5 on the roof) in the arrow direction opposite to the base. Towed). In the strength test of FIG. 14, both ends of the test fitting 200 are supported on a base (not shown) by the support 300. At this time, the interval between the columns 300 is equal to the interval between the columns 300 in FIG. And the pulling volt | bolt 400 is fixed to the center part between the both ends of the test metal fitting 200, and it is pulled by the predetermined force similar to the case of FIG. 13 in the arrow direction opposite to a base | substrate. As a result of the test in FIG. 13, the maximum displacement in the flat surface portion 11 was about ¼ to ５ of the maximum displacement of the fixed portion of the pulling bolt 400 of the test fitting 200 in FIG. 14. As described above, the metal fitting 10 of the first embodiment has an increased bending strength in a direction orthogonal to the flat surface portion 11.

  FIGS. 9 and 10 show a case where the roof is repaired by covering the top surface of the corrugated slate roof 6 with the first repair material 61 or the second repair material 62.
