Description

  The present invention relates to an attachment structure for a snow stop member, and more particularly to an attachment structure for a snow stop member for attaching a snow stop member to a solar power generation system in which a plurality of solar cell modules are installed on a roof. is there.

  As a solar power generation system that installs multiple solar cell modules on the roof, it is placed on the top of the crosspiece members across a plurality of long crosspiece members arranged at intervals on the roof and a plurality of crosspiece members There has been proposed a solar power generation system including a plurality of solar cell modules that have been formed and a fixing member that presses and fixes the solar cell module to a crosspiece member (for example, Patent Documents 1 to 3). When snow accumulates on the solar cell module, the upper surface of the solar cell module is flat and slippery, so that there is a problem that the accumulated snow slides at a time.

  In order to solve this problem, a technique has been proposed in which a cover that covers between the solar cell modules is provided with a snow stopper that extends upward in a plate shape (for example, Patent Document 4). Thereby, it is possible to prevent the accumulated snow from sliding down at a time by the snow stopper.

  However, in the technique of Patent Document 4, the fixing member for fixing the solar cell module is provided with a locking claw, and the cover is locked to the locking claw and attached. For this reason, when a load is applied to the cover via the snow stopper due to the accumulated snow, there is a possibility that the engagement with the engagement claw is released and the cover falls off.

  On the other hand, it is conceivable to extend the snow stopper from the fixing member instead of the cover. In this case, since the fixing member is fixed to the crosspiece member by a bolt, a nut, or the like, even if a load acts on the snow stopper due to the accumulated snow, the fixing member does not fall off. However, in this case, if the snow stopper is damaged by the accumulated snow load, it is necessary to remove the fixing member that fixes the solar cell module in order to replace the fixing member provided with the snow stopper. There is a problem that it takes time to mount and remove (replace) the member (snow stopper).

  Therefore, in view of the above circumstances, the present invention provides an attachment structure for a snow stop member that can be easily attached to and detached from a photovoltaic power generation system and that does not fall off even when a load due to accumulated snow acts. It is to be an issue.

In order to solve the above-mentioned problem, the mounting structure of the snow stopper member according to the present invention includes: “a plurality of long crosspiece members arranged on the roof at intervals in a direction perpendicular to the longitudinal direction; A plurality of solar cell modules placed across the top surfaces of the plurality of crosspiece members, a male screw portion projecting upward from the top surface of the crosspiece member between the adjacent solar cell modules, and the male screw A fixing member that penetrates through the fixing member and is in contact with a part of the solar cell module from above, a fixing nut that is fastened to the male screw portion that passes through the fixing member, and an upper side of the fixing nut A flat plate-shaped mounting plate portion in which the male screw portion penetrates and the shape in plan view is a rectangle that is long in a direction perpendicular to the flow direction of the roof, from one long side of the mounting plate portion of the solar cell module It extends upward from the top surface and The snow retaining portion extending to the direction perpendicular to the flow direction, and in that it is inserted between the solar cell module adjacent extended upward or downward from the pair of short sides of the mounting plate portion Comprising a snow stop member having a blocking portion that prevents the solar cell modules from approaching each other, and a mounting nut fastened to the male screw portion that penetrates the mounting plate portion of the snow stop member. '' Features.

  Here, as the “crosspieces” supported on the roof, “crosspieces arranged at intervals on the roofing material constituting the surface of the roof”, “intervals on the roofing material constituting the surface of the roof” A crosspiece member (crosspiece member assembled in the shape of a cross) supported on the upper side of the long support member arranged with a gap therebetween can be exemplified. Moreover, the longitudinal direction of the crosspiece member may be the flow direction of the roof, or may be a direction perpendicular to the flow direction of the roof (lateral direction of the roof).

  Further, as “a solar cell module placed on the top surface of the crosspiece member”, “a part of one side forming the outer periphery of the solar cell module is placed on the crosspiece member so as to intersect the longitudinal direction of the crosspiece member. "Solar cell module", "Solar cell module in which one side forming the outer periphery of the solar cell module is placed on the cross member over the entire length", and the like.

  The “male screw part” includes “a male screw part of a bolt having a head having a diameter larger than that of a male screw part such as a hexagonal bolt or a root bolt”, and a “male screw part of a bolt including only a male screw part”. And the like. The “male screw portion extending upward from the top surface of the crosspiece member” includes “a male screw portion supported so as to be slidable in the longitudinal direction of the crosspiece member” and “male male portion whose position is fixed to the crosspiece member. An example of the “thread portion” can be given.

  Furthermore, “the fixing member that is in contact with a part of the solar cell module from above” includes “the fixing member that is in contact with the upper surface of the solar cell module” and “the upper surface of the portion protruding from the side surface of the solar cell module”. Examples of the fixing member in contact with each other, “the fixing member in contact with the upper surface of the portion recessed from the side surface of the solar cell module”, and the like.

  Further, the “mounting plate portion” of the snow stop member may be disposed above the upper surface of the solar cell module, or may be disposed below the upper surface of the solar cell module. In addition, the “blocking portion” only needs to be able to block the solar cell modules from approaching each other. The “blocking portion extending to approximately the same length as the interval between the solar cell modules” and the “side surface of the solar cell module” In the case of a fixing member having a pair of extending portions extending along the blocking member, the blocking portion is inserted between the pair of extending portions and extends to substantially the same length as the distance between the pair of extending portions. '' Etc. can be illustrated.

  According to the mounting structure of the snow stopper member of the present invention, the snow retaining member is formed by fastening the mounting nut to the portion protruding upward from the fixing nut in the male screw portion passing through the fixing member fixing the solar cell module. The member is attached. That is, unlike the conventional technique in which the snow stopper member is attached to the fixing member via the locking claw, the snow stopper member is attached to the photovoltaic power generation system with the male screw portion (bolt) and the attachment nut. Therefore, even if a load acts on the snow stopper due to the accumulated snow, it is possible to prevent the snow stopper from falling off. Also, since the snow stop member is attached by tightening the mounting nut to the male thread that protrudes upward from the fixed nut, when replacing the snow stop member due to damage or the like, snow can be removed without removing the fixing nut or the fixing member. The stop member can be removed, and the snow stop member can be easily replaced.

  By the way, the solar cell module includes a flat plate solar cell panel whose plan view is formed in a polygonal shape such as a quadrangle, and a frame member that supports the outer periphery of the solar cell panel. The frame member of the solar cell module is generally formed to be hollow inside, and supports the solar cell panel near the top. And as a solar power generation system, when snow accumulates on the solar cell module (solar cell panel) installed on the inclined roof, the load by which the solar cell panel is pushed to the eaves side by the weight of the accumulated snow acts. It becomes. And there exists a possibility that the frame member arrange | positioned at the eaves side of a solar cell module may deform | transform with this load, or a fixing member may deform | transform depending on the shape of a fixing member.

  On the other hand, in the snow stop member mounting structure of the present invention, since the blocking portion is inserted between the adjacent solar cell modules, the blocking portion prevents the adjacent solar cell modules from approaching each other. Can do. Therefore, even if a load that pushes the solar cell panel of the solar cell module toward the eaves side is acted on by the accumulated snow, the load can be received by the blocking portion, so that the frame member of the solar cell module, the fixing member, etc. Deformation can be suppressed.

  Moreover, since the blocking part is inserted between the adjacent solar cell modules, the blocking part abuts against the solar cell module, thereby preventing the snow stop member from rotating around the male screw part. Therefore, when attaching the snow stop member to the solar power generation system, the orientation of the snow stop portion can be easily positioned by simply inserting the blocking portion between adjacent solar cell modules. Workability can be improved. In addition, when a load is applied to the snow stop portion due to the accumulated snow to rotate the snow stop member around the male screw portion, the blocking portion comes into contact with the solar cell module, so that the snow stop member Since the rotation is blocked, it is possible to prevent the direction of the snow stopper from changing due to the load, and the snow stopper effect can be maintained.

In addition to the above-described configuration, the snow stop member mounting structure according to the present invention is "the mounting plate portion has a length that the pair of opposed short sides straddle the adjacent solar cell modules". It is good as a feature.

  According to the mounting structure of the snow stopper member of the present invention, when the snow stopper member is mounted so that the mounting plate portion is placed on the upper surfaces of the solar cell modules on both sides across the adjacent solar cell modules, The mounting nut for attaching the snow stop member compared to the case where the mounting plate portion, that is, the mounting nut is arranged between the solar cell modules, is attached to the upper side of the solar cell module. This makes it easy to perform the rotation operation, and makes it easy to attach and remove the snow stopper.

  Thus, according to the present invention, it is possible to provide an attachment structure for a snow stopper member that can be easily attached to and detached from a photovoltaic power generation system and that does not fall off even when a load due to accumulated snow acts. Can do.

Then, in the same manner as described above, the fixing hole 15d of the intermediate fixing member 15A is passed through the male screw portion 14a of the root bolt 14A protruding upward from the upper surface of the crosspiece member 12 between the adjacent solar cell modules 13. At the same time, by fastening the fixing nut 16, the ridge side of the upper surface of the solar cell module 13 on the eave side and the eave side of the upper surface of the solar cell module 13 on the ridge side are pressed against the crosspiece member 12 by the intermediate fixing member 15A. And fix. Furthermore, when arrange | positioning the solar cell module 13 on the ridge side, the said operation | work is repeated and the solar cell module 13 is fixed to the crosspiece member 12. FIG.

  After that, when the eave side of the solar cell module 13 closest to the ridge is fixed to the crosspiece member 12, the length of the male screw portion 14a is short from the ridge side end of the crosspiece member 12 to the fixing groove 12b of the crosspiece member 12. The head 14b of the root bolt 14B is inserted and slid to the vicinity of the ridge side of the solar cell module 13. Then, the abutting portion 15c is brought into contact with the upper surface of the solar cell module 13 through the fixing hole 15d of the end fixing member 15B with respect to the male screw portion 14a. Thereafter, the flat washer 26 and the spring washer 27 are inserted into the male screw portion 14a, and the fixing nut 16 is fastened. Thereby, the ridge side of the upper surface of the solar cell module 13 is pressed against the crosspiece member 12 by the contact portion 15c of the end fixing member 15B, and the solar cell module 13 on the most ridge side is fixed to the crosspiece member 12. .

  And the installation of the solar power generation system S on a roof is completed by attaching the crosspiece cover 19 to the edge part of the ridge side of the crosspiece member 12 using the screw which is not shown in figure.

  When the photovoltaic power generation system S is installed on the roof, the male screw portion 14a of the male screw member 14 projecting upward from the upper surface of the solar cell module 13, that is, the hexagon bolt 14A and the root angle bolt 14B excluding the most ridge side. Each male screw portion 14a is inserted into the attachment hole 1d of the snow stopper member 1 from below. Then, the pair of blocking portions 1c of the snow stop member 1 are inserted between the adjacent solar cell modules 13 or between the eaves cover 18 and the solar cell module 13, and the mounting plate portion 1a is inserted into the solar cell module 13. It is mounted on the upper surface (the upper surfaces of the pair of contact portions 15c of the intermediate fixing member 15A). In this state, the plain washer 28 and the spring washer 27 are inserted into the male screw portion 14a, and the mounting nut 29 is fastened. Thereby, it will be in the state where the snow stop member 1 was attached to the photovoltaic power generation system S. The snow stop member 1 may be attached during the installation work of the solar power generation system S.

  Here, when attaching the snow stop member 1, it attaches so that the snow stop part 1b may become the eaves side. Thereby, since the snow stop part 1b becomes a position away from the solar cell module 13 on the ridge side, it is possible to reduce the snow stopped by the snow stop part 1b from staying on the solar cell module 13 on the ridge side. Therefore, it can suppress that the solar cell panel 13a of the solar cell module 13 is covered with the snow stopped by the snow stop part 1b, and power generation efficiency falls.

  Moreover, by attaching the snow stopper 1b toward the eaves side, the shadow of the snow stopper 1b is less likely to be applied to the solar cell module 13, and a reduction in power generation efficiency can be suppressed. In other words, the height of the snow stopper 1b can be further increased (for example, a height of 25 mm to 35 mm) within a range in which the power generation efficiency is not reduced. Thereby, the snow stop member 1 having a high snow stop portion 1b can be used, and a more excellent snow stop effect can be exhibited while maintaining power generation efficiency.

  Further, the diameter of the plain washer 28 for attaching the snow stopper member 1 is set to a length straddling the pair of contact portions 15c of the intermediate fixing member 15A as shown in FIGS. Thereby, since the mounting plate part 1a of the snow stop member 1 can be reinforced by the large diameter flat washer 28, the mounting plate part 1a is prevented from being bent when the mounting nut 29 is fastened.

  Thus, according to the mounting structure of the present embodiment, the male screw portion 14a penetrating the fixing member 15 (intermediate fixing member 15A) fixing the solar cell module 13 protrudes upward from the fixing nut 16. The snow stopper member 1 is attached to the portion by fastening the attachment nut 29. That is, the snow stop member 1 is attached by the male screw portion 14 a (bolt) and the attachment nut 29. Therefore, even if a load acts on the snow stop 1b due to the accumulated snow, the snow stop member 1 can be prevented from falling off. Further, since the snow stopper member 1 is attached by fastening the mounting nut 29 to the male screw portion 14a protruding upward from the fixing nut 16, when replacing the snow stopper member 1 due to damage or the like, the fixing nut 16 or the fixing member The snow stopper member 1 can be removed without removing 15 or the like, and the snow stopper member 1 can be easily replaced.

  Moreover, in the attachment structure of this embodiment, since the prevention part 1c is inserted between the adjacent solar cell modules 13, it can prevent that the adjacent solar cell modules 13 approach by the prevention part 1c. . Therefore, even if a load that pushes the solar cell panel 13a of the solar cell module 13 toward the eaves side is applied by the accumulated snow, the load can be received by the blocking portion 1c, and therefore the frame member 13b of the solar cell module 13 And the deformation of the fixing member 15 and the like can be suppressed. For example, in the intermediate fixing member 15A, the upper end sides of the pair of extending portions 15b can be prevented from being deformed in a direction in which they approach each other.

  Further, since the blocking portion 1c is inserted between the adjacent solar cell modules 13, the snow stop member 1 rotates around the male screw portion 14a when the blocking portion 1c contacts the solar cell module 13. Is blocked. Therefore, when attaching the snow stop member 1 to the photovoltaic power generation system S, the orientation of the snow stop portion 1b can be easily positioned by simply inserting the blocking portion 1c between the adjacent solar cell modules 13. The workability of attaching the stopper member 1 can be improved. In addition, when a load for rotating the snow stopper member 1 around the male screw portion 14a is applied to the snow stopper portion 1b by the accumulated snow, the blocking portion 1c comes into contact with the solar cell module 13 to Since the rotation of the stopper member 1 is prevented, it is possible to prevent the direction of the snow stopper portion 1b from being changed by the load, and the snow stopper effect can be maintained.

  Further, in the mounting structure of the present embodiment, the short side of the mounting plate portion 1a is set to a length straddling the adjacent solar cell modules 13, and the mounting plate portion 1a extends across the two solar cell modules 13 so that the solar cell modules 13 on both sides. The snow stopper member 1 is attached so as to be placed on the upper surface. As a result, the mounting nut 29 to which the snow stopper member 1 is attached is located above the solar cell module 13, so that the mounting nut 29 can be easily rotated, and the snow stopper member 1 can be easily attached and removed. Can do.
