  The prior art will be described with reference to FIGS. 9 to 11.

  FIG. 9 is FIG. 1 of JP-A-2017-75527. In FIG. 9 (a), the long side of the solar cell panel 1 is disposed parallel to the flow direction of the disposed roof so that the long side of the solar cell panel 1, 1 'is along the flow direction of the folded plate roof 30 In a fixed state. And with respect to the go parts 35 and 35 'of the folded plate roof 30, the carrying out fitting 4 is attached by predetermined spacing, and the solar cell panel 1 is attached on it. (B) has shown the carrying out metal fitting 4, and the main body 4A, the connection frame 4B, and the vertical bolt 4C are combined in the engaged state.

  However, the prior art shown in FIG. 9 does not disclose the description on the installation of the solar cell module to the pitch of the folded plate roof. Since the pitch of the folded plate roof and the short side length of the solar cell panel are different from each other, they may not be combined well, and it may be necessary to reduce the number of installation with respect to the roof area. In addition, in order to install the solar cell module in contact with the connecting frame 4B and install it according to the pitch of the folded plate roof, the main body 4A, the connecting frame 4B and the vertical bolt 4C are engaged. It was necessary to combine in the shape and to set it as the carrying out bracket 4. Furthermore, in the case of the mounting members 6A and 6B in the case where the roofs are inclined in the flow direction, the body has to be set to a height and a length corresponding to the inclination angle.

  In the prior art shown in FIG. 10, in order to change the frame interval of the solar cell module, the variation of the cover body 40 was required. Moreover, a solar cell module is put in order and installed in the flow direction of a roof, and a mounting bracket is arrange | positioned between the frames of adjacent modules. Therefore, in the case where the solar cell module is mounted in an inclined manner, another mechanism has been required to make the frame interval of the solar cell module constant.

  In the prior art shown in FIG. 11, since the solar power generation unit is fixed at the end of the roof in the flow direction, the holding low holding tool and the holding high holding tool are the size and inclination of the solar power generation unit. Many variations were needed depending on the combination of angles.

  The present application is a mounting structure of the installation on the roof using a fixing member attached to the ridge of the vertical roof and a spacer for securing a space between the installation on the roof adjacent in the direction perpendicular to the flow of the roof. is there. This spacer is combined with the fixture, and the distance between the on-roof installations secured by the spacer is approximately equal to the integral multiple of the roof pitch, the sum with the short side length of the on-roof installation. The short side of the installation on the roof is disposed in a direction perpendicular to the flow of the roof, and the long side of the installation on the roof is mounted on the fixture.

  Further, in addition to the above, in the ridges of the vertical roof, a fixture in which low pedestals are combined and a fixture in which high pedestals are combined are attached. An installation on the roof is attached in an inclined manner on the low pedestal and the high pedestal.

  The spacer of the present application can be easily achieved because it is only combined with standing bolts such as fasteners and spacer mounting grooves. The cost is low and the installation is easy. Therefore, the installation on the roof in the row direction can be stably fixed according to the pitch of the vertical roof. Moreover, what is necessary is just to prepare the thing of the angle and height according to the inclination angle about the low pedestal and high pedestal of this application.

  The present application can cope with various spacings on the roof installation only by replacing the spacers having different spacings in the row direction. Moreover, the spacer of this application is arrange | positioned between the roof top installations which adjoin in the direction orthogonal to the flow of a roof. Therefore, even if the installation on the roof is installed by being inclined, the same spacer can be used without providing another mechanism.

  In the present application, the side (long side) orthogonal to the flow of the roof is fixed, not the flow direction of the roof, so the low pedestal and the high pedestal may be only those according to the inclination angle, and the size of the installation on the roof It does not matter. Moreover, since a continuous intermediate support member etc. are not used, the space | interval of the solar cell modules adjacent in the flow direction of a roof can be easily expanded / contracted in the field.

  An embodiment of the mounting structure for installation on a roof according to the present application will be described with reference to FIGS. 1 to 8.

FIG. 2: is explanatory drawing which shows the Example of the attachment structure of the installation on a roof of this application. FIG. 3: is explanatory drawing which shows the Example of the fixing tool used by the attachment structure of the roof top installation thing of this application, a spacer, a pressing tool, and a nut. FIG. 4 is an example of a fixture, a low pedestal, a spacer, a presser, and a nut used in the mounting structure of the installation on a roof according to the present invention. FIG. 5 shows an example of a fixture, a high pedestal, a spacer, a presser, and a nut used in the mounting structure of the installation on a roof according to the present invention. 6 to 8 show examples of the mounting structure of the on-the-roof installation of the present application.

  In the present application, the on-the-roof installation item E having a substantially rectangular shape indicates a photovoltaic panel, a solar heat collecting panel, and the like. It is of a so-called panel type (board type), having a predetermined thickness and having a flat and substantially rectangular shape. In the present application, although the size or the like is not limited, it is suitable that the size is set to a certain extent. Among them, the solar panels are most suitable because the majority of them have a short side length of 900 mm or more and less than 990 mm.

  In the present application, the vertical roof Y refers to one having ridges Y12 along the flow of the roof, such as folded plates, tiled bars, and warps. In the present application, the roof pitch P refers to a dimension of one unit constituting a shape in which the same shape is repeated. For example, as shown in FIG. 2, in the case of the goby folded plate, the ridge portion Y 1, the sloped portion Y 2, the valley portion Y 3, and the sloped portion Y 2 form one unit. In the present invention, the roof pitch P is most preferably 333 mm or 500 mm, which is large for the folded flaps.

  In the case where the on-the-roof installation E is attached to the vertical roof Y, the fixing tool K may be attached to the protrusion 12. Generally, the long side of the on-roof installation E is disposed in a direction perpendicular to the flow of the roof, and the long side is fixed at the lower side end and the upper side end of the water. This is because the position at which the installation E on the roof is fixed is limited to the vicinity of immediately above the ridge 12 of the vertical roof Y, so the long side, which is the longer side, is combined for easy alignment. In this way, on-roof installations E of various sizes are attached to the vertical roof Y of various roof pitches P.

  On the other hand, although it is not common, a method is used in which the short side of the on-roof installation E is disposed in the direction perpendicular to the flow of the roof, and the short side is fixed at the lower water end and upper water end. In some cases, In this case, the roof pitch P may not be met unless the arrangement distance between the roof-mounted objects E and E adjacent to each other in the direction perpendicular to the flow of the roof is set. Moreover, the fixed position of the on-the-roof installation E is separated by the length of the long side on the water side and the water upper side, so the stability of the mounted state is low. Therefore, it is preferable to fix the long side, but it is necessary to make the short side length W of various on-roof objects correspond to various roof pitches P. For example, a structure corresponding to various roof pitches P is often used by using a long horizontal bar or the like. But this was costly.

  Here, when the short side length W of the installation on the roof such as a photovoltaic panel is 900 mm or more and less than 990 mm, if the interval of several tens of mm can be adjusted without using a long horizontal bar etc. It can be attached to the folded plate in an arrangement corresponding to an integral multiple of 333 mm or 500 mm. The spacer S of the present application secures a space between the roof-mounted objects E and E adjacent to each other in the direction orthogonal to the flow of the roof.

  The spacer S of the present embodiment shown in FIG. 1 has a shape in which a strip-like plate material is stepped. The substantially central portion of the strip-shaped plate material is raised in a substantially inverted U-shape, and has a hole S1 at the top, and the combined raising surface is the on-roof installation object contact portion S2 · S2. Moreover, the both ends are folded down as rotation stop part S3. A conductive projection S4 is formed between the rotation stopping portion S3 and the on-the-roof installation provided contact portion S2 to project to the upper surface side.

  The holes S1 and the rotation stoppers S3 of the spacer S of this embodiment are used when combined with the fixture K of the on-the-roof installation E. The standing bolt K1 is inserted into the hole S1. Only by this, the spacer S may be combined with the fixture K, and does not have to be fixed using a bolt, a nut or the like. In addition, when the spacer S is combined with the fixture K, the rotation stopping portion S3 of the spacer S is abutted against the side surface of the fixture K to prevent the spacer S from rotating around the standing bolt K1. It has become. Therefore, the on-the-roof installation thing E attached is held down by the spacer S, is not rotated, and can maintain a stable installation state. In the fixing tool K, a spacer mounting groove K21 may be formed in the mounting portion K2 on the upper surface. The spacer mounting groove K21 is formed in a width in which the spacer S fits, and prevents the spacer S from rotating around the erecting bolt K1 of the fixing tool K.

  In the present application, as shown in FIG. 2, the sum of the distance G formed by the spacer and the short side length W of the installation on the roof is substantially equal to an integral multiple of the roof pitch P. For example, when the on-roof installation E having a short side length W of 977 mm is attached to the vertical roof Y having a roof pitch P of 500 mm, the spacing G formed by the spacers is 23 mm, and the roof pitch is It is equal to twice P (500 × 2 = 23 + 977). In addition, when the on-roof installation E with a short side length W of 977 mm is attached to the vertical roof Y with a roof pitch P of 333 mm, the spacing G formed by the spacers is 22 mm. It becomes equal to 3 times the pitch P (333 × 3 = 22 + 977).

  In the prior art described in FIG. 10, the partition protrusion 15 used when the lower side and upper side of the installation on a roof are fixed is formed. The partition projection 15 is positioning on the folded plate roof attachment fitting, and the position also changes depending on the arrangement position of the folded plate roof attachment fitting. On the other hand, the on-the-roof installation attachment parts S2 and S2 of the present application are formed to face the under-water side end or the on-water upper end of the on-roof installation E aligned in the flow direction of the roof. Therefore, the proper spacing between the roof installations E and E adjacent to each other in the flow direction of the roof is secured, and it serves as a guide for mounting at the correct position in the flow direction of the roof. In addition, it plays a role of preventing the installation E on the roof from sliding to the water side. Therefore, the spacer of this application is positioning which defines the attachment position of the on-roof installation thing with respect to a roof surface, Comprising: The partition protrusion 15 of FIG. 10 and the on-roof installation thing contact part of this application are completely different.

  The conductive projections S4 of the spacer S of the present embodiment can electrically connect on-the-roof installed objects E · E such as photovoltaic panels mounted on one fixture K. In this case, the spacer S is most preferably made of a conductive metal. By the conductive projections S4 and S4, the adjacent solar photovoltaic panels in the direction orthogonal to the flow of the roof are simply attached to each other to be in a conductive state, and it is possible to save time and effort for grounding connection.

  Next, the mounting structure (tilted installation) of the installation on the roof of the present application will be described. In the present application, the on-the-roof installation E can be inclined and attached by using the low pedestal L and the high pedestal H having different heights from the roof surface to the on-roof installation. In the present embodiment, in the low pedestal L and the high pedestal H, the hole L1 or the hole H1 is inserted through the erected bolt K1 and placed on the fixture K. Further, the spacer S, the presser O, and the nut N are inserted into and combined with the erecting bolt K1 of the fixture K or the erecting bolt H5 of the high pedestal H.

  The low pedestal L of the present embodiment is a member disposed on the low side when the on-the-roof installation E is attached in an inclined manner. The upper surface on which the predetermined inclination is formed is the placement unit L2. In the mounting portion L2, a spacer mounting groove L21 is formed, and a hole L1 is provided at a substantially central portion thereof. The spacer mounting groove L21 is formed in a width in which the spacer S fits, and prevents the spacer S from rotating around the erecting bolt K1 of the fixing tool K. Further, at the water upper end of the low pedestal L of the present embodiment, a hanging detent piece L3 is provided. When the spacer S is mounted on the spacer mounting groove L21, the rotation stopper piece L3 is in contact with the side surface of the fixture K, and the low pedestal L rotates around the standing bolt K1 of the fixture K Play a role in preventing

  The high pedestal H of the present embodiment is a member disposed on the high side when the installation E on the roof is attached in an inclined manner. The upper surface on which the predetermined inclination is formed is the placement unit H2. A spacer placement groove H21 is formed in the placement portion H2, and has a one-step deep standing bolt groove H4. The spacer mounting groove H21 is formed to have a width in which the spacer S fits, and prevents the spacer S from rotating about the erecting bolt H5 of the high pedestal H. The head of the erecting bolt H5 is slid from the side opening into the erecting bolt groove H4, and combined so as not to be pulled upward. The position of the erecting bolt H5 is determined by combining the spacer S with the spacer mounting groove H21 so that the rotation stoppers S3 and S3 of the spacer S abut on the high pedestal H, and can not slide. . Further, at the lower end of the high pedestal H of the present embodiment, the suspended detent piece H3 is provided. The rotation stopper piece H3 is in contact with the side surface of the fixing tool K, and prevents the high pedestal H from rotating around the standing bolt K1 of the fixing tool K. In the high pedestal H, a hole H1 is formed on the bottom surface. In the high pedestal H, the hole H1 is inserted into the standing bolt K1 of the fixture K, and is attached by a nut N.

  Thus, the spacer S in the present application can be combined with any of the fixture K, the low pedestal L, and the high pedestal H. Also, even when the installation E on the roof is installed with inclination using the low pedestal L and the high pedestal H as in the present embodiment, it is mounted on one fixture K by the conductive projection S4 of the spacer S. Roof mounted objects E and E such as solar panels can be conducted to each other. In this case, the spacer S is most preferably made of a conductive metal. By the conductive projections S4 and S4, the adjacent solar photovoltaic panels in the direction orthogonal to the flow of the roof are simply attached to each other to be in a conductive state, and it is possible to save time and effort for grounding connection. This is not possible with a continuous intermediate support such as the prior art shown in FIG. That is because the ends of the on-roof installation objects are separated from each other on the high side and the low side, and it is necessary to arrange many variations according to the size and inclination angle of the on-roof installation.

  In this embodiment, the fixture K under the water on which the low pedestal L is combined and the fixture K on the upper side of the water where the high pedestal H is combined are adjacent to each other in the flow direction of the roof. It is attached to the ridge. The fixing tool K of the present embodiment is fixed on the roof by sandwiching the projection Y12 of the vertical roof Y at the holding portions K3 and K3. In addition, on the upper surface of the fixing tool K, there is provided a standing bolt K1 whose shaft portion is directed upward. When the low pedestal L is combined, the standup bolts K1 of the fixture K of this embodiment are combined with the spacer S, the presser O, and the nut N. On the other hand, when the high pedestal H is combined, the one having another standing bolt H5 on the upper surface is fixed by a nut. In addition, the spacer S, the pressing tool O, and the nut N are combined with the erecting bolt H5 of the high pedestal H of the present embodiment.

  In the present embodiment, the pressing tool O is used. The installation on the roof E is attached by clamping the nut N so that the long side is sandwiched between the low pedestal L or the high pedestal H and the pressing tool O. In the present embodiment, on the bottom surface of the pressing tool O, there are provided two ridges O2 · O2 formed with the same width as the gap G formed by the spacer. The ridges O2 and O2 play a role of preventing the installation object E on the roof from being blown up by the wind, and the adjacent upper surfaces are close to each other to become substantially V-shaped.

  The mounting structure of the installation on the roof according to the present embodiment can change the inclination angle at which the installation E on the roof is attached, only by changing only the low pedestal L and the high pedestal H to different inclinations. At this time, the same fastener K, spacer S, presser O, nut N, etc. can be used. This is because the roof pitch P and the short side length W of the on-roof installation do not change even if the inclination angle of the on-roof installation P is changed as shown by the broken line in FIG. 7. Therefore, the variation of the members can be reduced.

  In the mounting structure of the installation on the roof according to the present embodiment, the long side length is indicated by a broken line in FIG. 8 if the mounting interval of the fixture K in the flow direction of the roof is constant when the inclination angle is the same. Even in the case of a different on-the-roof installation item E, the same thing can be used as the fixture K, the low pedestal L, the high pedestal H, the spacer S, the presser O, the nut N, and the like. This is determined by the height of the low pedestal L and the height of the high pedestal H and the distance between them, and the inclination angle is determined naturally, so that the installation E on the roof has a long side larger than the attachment distance between the low pedestal L and the high pedestal H If it is, it can be attached similarly. Therefore, the variation of the members can be reduced. Moreover, it is also easy to expand and contract the space between the roof-mounted objects E and E adjacent to each other in the flow direction of the roof. For this reason, it is possible to arrange in consideration of the shadows of nearby standing trees, roof installation itself, etc., or to narrow the distance between roof roof installations E and E adjacent to each other in the flow direction of the roof to maximize the number of installation. Installation according to the situation is possible.
