Description

  The present invention relates to a solar cell module fixing member for fixing a solar cell module on a roof, and a solar cell module fixing structure.

  Conventionally, as a fixing structure for fixing a solar cell module formed in a panel shape on a roof, for example, as shown in Patent Document 1, to a field plate as a building structural member on which a roofing material such as a roof tile is laid. After attaching the roof fixing brackets at a predetermined interval, attach a long vertical bar to the roof fixing bracket, and then add a plurality of long horizontal bars to bridge the multiple vertical bars The solar cell modules are fixed on the roof by attaching them at intervals and supporting the solar cell modules with adjacent horizontal members.

JP 2006-37545 A

  However, in the conventional fixing structure of the solar cell module, in order to fix the solar cell module on the roof, many members such as a roof fixing metal fitting, a vertical gutter material, and a horizontal gutter material are required. The members had to be assembled on a roof with a poor scaffold, and there was a problem that the labor involved in installing the solar cell module increased and the cost increased.

  In addition, the solar cell module is fixed on the roof through the vertical and horizontal gutters assembled in a cross-beam shape, and particularly the solar cell module on the upper side of the roof material as shown in the cited document 1. Is fixed, the step between the surface of the roofing material and the surface of the solar cell module becomes large, and there is a problem that the appearance is deteriorated.

  Therefore, the solar cell module can be directly mounted and fixed on the roofing material or the field plate using a predetermined fixing member without using the vertical and horizontal members that are assembled in a cross-beam shape, thereby reducing the number of parts. It is conceivable to reduce the level difference from the roofing material. However, in this case, since the external dimensions of the conventional solar cell module do not correspond to the laying pitch of the roofing material, the position where the fixing member is attached to the roofing material varies, and the same fixing member should correspond. Therefore, it is necessary to prepare a plurality of types of fixing members. More specifically, when a fixing member must be attached to the boundary between the roofing material and the roofing material, there is a step between the roofing material and the roofing material, so that the fixing member has a shape that can absorb the step. It is necessary to. In addition, when slate is used as the roofing material, if a fixing member is fixed to the part where the slate exposed on the surface and the slate directly below it overlap, capillarity occurs between the slate and rainwater flows to the back of the roofing material. There is a problem that causes infiltration of rain and leaks. Therefore, it is necessary to prepare a plurality of fixing members having a shape corresponding to the position to be attached to the roofing material, or special brackets are required, which can be troublesome by increasing the number of parts or using expensive brackets. There is a problem that costs.

  Therefore, in view of the above situation, the present invention provides a solar cell module fixing member and a solar cell module fixing structure capable of reducing the number of parts and reducing the cost and fixing the solar cell module in a suitable state. Is an issue.

The solar cell module fixing member according to the present invention includes: “a support portion for supporting a solar cell module whose outer dimension is an integral multiple of a laying pitch of a roof material laid on a building structure member; The solar cell module supported by the support portion is substantially parallel to the building structure member, and is fixed to the building structure member via the roof material with respect to a portion that is integrally formed and exposed on the surface of one roof material. And a fixing portion having a bottom surface that is inclined so as to be . ” In the following description, the “solar cell module fixing member” is also simply referred to as “fixing member”.

  Here, examples of the “roof material” include slate (color vest), ceramic tile, metal tile, cement tile, and tin. In addition, as the “integer multiple”, the laying pitch of the roofing material is usually about 150 mm to 450 mm, and is desirably 2 to 8 times the pitch. Or it is desirable to set it as the integer multiple which the one side of the external dimension of a solar cell module becomes in the range of 500 mm-2000 mm.

  In addition, the “supporting portion” includes “a fitting projection that fits into the fitting groove formed in the solar cell module”, “a claw shape that engages with the engaged portion formed in the solar cell module. And the like "," one provided with both the fitting protrusion and the engaging part ", and the like. Moreover, as a support part, while being able to support each (two) solar cell module arrange | positioned adjacent on both sides of a solar cell module fixing member, the surface of the solar cell module arrange | positioned adjacently is substantially on the same surface. It is desirable to support it.

  According to the present invention, the solar cell module fixing member for fixing the solar cell module on the roof by fixing the solar cell module whose outer dimension is an integral multiple of the laying pitch of the roof material laid on the building structure member, The battery module is configured by a support portion that supports the battery module and a fixing portion that is integrated with the support portion and is fastened to the building structure member.

  Thereby, a solar cell module can be installed on a roof, without using a vertical fence material or a horizontal fence material conventionally, and the kind of member for installing and fixing a solar cell module can be reduced. At the same time, since the solar cell module is directly fixed to the building structure member such as a field board or a rafter by the fixing member, the labor involved in installing the solar cell module can be simplified and the cost can be reduced. .

  In addition, since the solar cell module is directly fixed to the building structural member by the fixing member, compared to the case where the solar cell module is installed by assembling the vertical bar material and the horizontal bar material like a conventional one, The level difference between the surface of the solar cell module and the surface of the roofing material can be reduced as much as possible, and the appearance can be prevented from being deteriorated when installed on the roof.

  Furthermore, since the outer dimensions of the solar cell module are an integral multiple of the laying pitch of the roof material, the position where the fixing member that supports the solar cell module is arranged (fixed) to the roof material is a substantially constant position. The solar cell module can be fixed with the same type of fixing member, the number of parts can be reduced, the cost can be reduced, and each solar cell module is fixed with the same type of fixing member, so the type of fixing member Can be saved, and workability can be improved.

  Moreover, since the external dimensions of the solar cell module are an integral multiple of the laying pitch of the roof material, it is avoided that the fixing member for fixing the solar cell module is disposed at a position where the roof materials overlap each other. When the slate is used as the roofing material, it is possible to avoid the occurrence of capillary action between the overlapping slate, and to prevent the installation of the solar cell module from causing rain leakage.

  In addition, it is desirable that the fixing member is configured to be slidable along the side supporting the solar cell module, whereby the optimum position (for example, for the roof structure member, for example, regardless of the position of the solar cell module). It is easy to fix and fix the fixing member at the position where the capillarity phenomenon is difficult to occur between the overlapping roof materials, the position where the rafters are arranged, etc., to prevent the occurrence of rain leakage and the fixing of the solar cell module The strength can be increased.

  In addition, the solar cell module itself may be provided with a function as a roofing material. In the portion where the solar cell module is installed, a double roof structure is formed with the solar cell module and the lower roofing material. The function can be further enhanced, and the fixing member is not directly exposed to wind and rain, and the occurrence of rain leakage at the site where the fixing member is fastened can be prevented.

  According to the present invention, the solar cell module is fixed by the solar cell module fixing member on the upper and lower sides of the solar cell module with respect to the flow direction of the roof, and further, the fixing portion of the fixing member is constructed through the roof material. The solar cell module supported by the support portion is inclined so that the solar cell module supported by the support portion is substantially parallel to the building structure member.

  Thereby, even if the inclination angle of a roof material differs from the inclination angle of a building structure member, the inclination angle of the solar cell module supported by a fixing member can be made into the substantially same inclination angle as a building structure member. In particular, when the adjacent solar cell modules are supported on substantially the same surface in the support portion of the fixing member, a plurality of solar cell modules installed on the roof by the fixing member are arranged and fixed on the substantially same surface, respectively. Can get a good aesthetic.

  Moreover, since the solar cell module is fixed by the fixing member on the upper and lower sides with respect to the flow direction of the roof, the solar cell module can be prevented from moving downward in the flow direction by the fixing member. As a result, the fixing member can be slid with respect to the side supporting the solar cell module, and the fixing member is fastened and fixed to the optimal position with respect to the roof material regardless of the installation position of the solar cell module. Thus, the solar cell module can be installed on the roof in good condition.

  Furthermore, the solar cell module fixing member according to the present invention has, in addition to the above configuration, “the support portion has an engaging portion that engages with an engaged portion formed in the solar cell module”. It is characterized by that.

  According to the present invention, the support portion of the solar cell module fixing member is provided with the engaging portion that engages with the engaged portion formed in the solar cell module. Thereby, the solar cell module can be fixed and supported more firmly by the fixing member, and even if a load such as strong wind acts on the solar cell module installed on the roof, it is difficult to come off and the solar cell is in a good state. Module can be fixed.

The fixing structure of the solar cell module according to the present invention is “with respect to a portion of the solar cell module fixing member according to claim 1 or 2 exposed on the surface of the roof material laid on the building structural member, In the flow direction of the roof, the solar cell module is fixed in the vicinity of the lower end of the roofing material arranged on the upper side and in the roof girder direction within a range of a predetermined distance from the boundary of the girder side. Features.

Within the range to the bottom of the material. Further, the “predetermined dimension from the border on the digit side” is within the range of 30 mm to 100 mm, preferably 50 mm to 80 mm from the border. If the dimensions are smaller than the above-mentioned dimensions, there is a possibility that capillarity occurs between the overlapping roofing materials and may cause rain leakage, and if the dimensions are larger than the above-mentioned dimensions, the fixing member is attached to the exposed part of the roofing materials. This is because it may be difficult to secure a space for fastening.

  According to the present invention, the solar cell module fixing member described above has a predetermined dimension from the boundary in the girder direction in the vicinity of the lower end of the roof material laid on the upper side in the flow direction with respect to the portion exposed on the surface of one roof material. The solar cell module is fixed within the range of the distant position.

  Thereby, by fixing and fixing a fixing member in the above-mentioned range, it can prevent that a capillary phenomenon generate | occur | produces between the overlapping roof materials, and can cause a rain leak. In particular, when a slate such as a color vest is used as a roofing material, the slate is thinner and easier to deform than a tile. However, it is possible to prevent the occurrence of capillarity at the end of the roofing material by keeping the fixing member within the above range away from the end of the roofing material that becomes the source of rainwater and other intrusions. Can be avoided.

'' It is characterized by that.

  According to the present invention, the solar cell module whose outer dimension in the flow direction is an integral multiple of the laying pitch of the roofing material, and the engagement with the engaged portion formed at the upper end in the flow direction of the solar cell module. A support part that has a joint part and supports the upper and lower ends of the solar cell module, is formed integrally with the support part and is fastened to the building structure member via the roofing material, and the solar cell module is substantially parallel to the building structure member A solar cell module fixing member having a fixing portion having a bottom surface inclined to the upper side in a flow direction with respect to a portion exposed on the surface of the roofing material laid on the building structural member.

The fixing member 3 may be fitted by inserting the fixing member 3 from a direction perpendicular to the longitudinal direction of the frame body 6 or by inserting the fixing member 3 from the longitudinal end portion of the frame body 6. When the fixing member 3 is fitted from a right angle direction, the engaging portion 3i and the engaged portion 6d, whose tips are tapered to each other, are elastically deformed and easily engaged. The part 3i and the engaged part 6d can be engaged with each other.

  Then, after the fixing member 3 is fitted into the upper frame body 6 of the solar cell module 4, the fixing member 3 is appropriately slid in the spar direction and arranged within the above-described range in the exposed roof material 2, and the fastening screw 7 The fixing member 3 is fastened and fixed to the building structure member 1 by using. In addition, in this example, since the dimension of the flow direction of the solar cell module 4 is an integral multiple of the laying pitch Pa of the roofing material 2, the upper side of the solar cell module 4 is supposedly above the roofing material 2. The position in the flow direction of the fixing member 3 to be supported is arranged at substantially the same position as the position of the fixing member 3 to support the lower side of the solar cell module 4, and the flow direction is automatically within the range described above. Be placed. Further, the bottom surface of the fixing member 3 is inclined as described above, and the solar cell module 4 fixedly supported by the fixing member 3 is in a state substantially parallel to the building structure member 1.

  In the solar cell module 4 fixed by the fixing member 3, the lower surface of the lower frame body 6 is placed on the second pedestal portion 3 f of the fixing member 3, and the lower surface of the upper frame body 6 is fixed to the fixing member 3. Is placed on the first pedestal 3e. As a result, the solar cell module 4 is supported not only by the first projecting piece 3a and the second projecting piece 3b of the fixing member 3, but also by the first pedestal 3e and the second pedestal 3f, Movement in the direction perpendicular to the direction in which the structural member 1 extends is restricted. Further, as shown in FIG. 2, the solar cell module 4 is configured such that the tips of the upper and lower pieces constituting the lower groove 6 c of the frame body 6 come into contact with the standing wall piece 3 c of the fixing member 3. Movement in the flow direction is regulated.

  After fixing the lowermost solar cell module 4 on the roof in this way, subsequently, a new solar cell module 4 is arranged on the upper side, and the fixing member 3 fixed on the roof is attached to the fixing member 3 as described above. The lower frame 6 of the solar cell module 4 is supported, and then a new fixing member 6 is further fitted into the upper frame 6, and the fixing member 6 is fixed to the roofing material 2 in the same manner as described above. Thus, the upper solar cell module 4 is fixed. As shown in the figure, the first projecting piece 3a and the second projecting piece 3b of the fixing member 3 extend so as to be continuous with the standing wall piece 3c interposed therebetween, and the sun disposed vertically with the fixing member 3 interposed therebetween. The battery module 4 is fixed and supported on substantially the same surface. And a plurality of solar cell modules 4 will be installed on a roof by repeating the above-mentioned work one by one.

  The decorative cover 8 may be attached to the fixing member 3 when the lowermost fixing member 3 is fixed to the roofing material 2, or may be attached to the fixing member 3 after fixing the solar cell module 4. Anyway.

  As described above, according to the fixing member 3 of the present embodiment, the solar cell module 4 can be installed on the roof without using a vertical fence material or a horizontal fence material as in the prior art, and a member for fixing the installation. Since the solar cell module 4 is directly fixed to the building structural member 1 such as a field board or a rafter by the fixing member 3, the labor involved in the installation of the solar cell module 4 can be simplified. This can reduce the cost.

  Moreover, since the solar cell module 4 is directly fixed to the building structure member 1 by the fixing member 3, the case where the solar cell module 4 is installed by assembling the vertical fence material and the horizontal fence material in a conventional manner. In comparison, the step difference between the surface of the solar cell module 4 and the surface of the roofing material 2 can be reduced as much as possible, and deterioration in appearance can be suppressed when installed on the roof.

  Furthermore, since the outer dimension of the solar cell module 4 is an integral multiple of the laying pitch Pa of the roof material 2, the position where the fixing member 3 that supports the solar cell module 4 is arranged and fixed with respect to the roof material 2 is approximately. The solar cell module 4 can be fixed with the same type of fixing member 3, and the cost can be reduced by reducing the number of components, and each solar cell module 4 with the same type of fixing member 3 can be fixed. Therefore, the labor of selecting the type of the fixing member 3 can be saved, and workability can be improved.

  Moreover, since the external dimension of the solar cell module 4 is an integral multiple of the laying pitch Pa and Pb / 2 of the roof material 2, the roof member 2 is overlapped with the fixing member 3 that fixes the solar cell module 4. It is possible to avoid being arranged at a position, to prevent the capillary phenomenon from occurring between the roofing materials 2 made of overlapping slate, and the installation of the solar cell module 4 causes rain leakage. Can be prevented.

  Moreover, since the fixing member 3 is configured to be slidable along the side supporting the solar cell module 4, an optimal position (for example, relative to the roof structure member 1) regardless of the position of the solar cell module 4. The fixing member 3 can be fastened and fixed to a position where the capillarity is unlikely to occur between the overlapping roofing materials 2, the position where the rafters are arranged, etc., and it is possible to prevent the occurrence of rain leakage, The fixing strength of the module 4 can be increased.

  Furthermore, even if the inclination angle of the roofing material 2 is different from the inclination angle of the building structural member 1, the inclination angle of the solar cell module 4 supported by the fixing member 3 can be set to be substantially the same as that of the building structural member 1. Therefore, the plurality of solar cell modules 4 installed on the roof by the fixing member 3 can be arranged and fixed on substantially the same plane, and a good aesthetic appearance can be obtained.

  Further, since the support portion of the fixing member 3 is provided with the engaging portion 3i that engages with the engaged portion 6d formed on the solar cell module 4, the solar cell module 4 is thereby fixed by the fixing member 3. The solar cell module 4 can be fixed in a good state because it is difficult to come off even when a load such as strong wind acts on the solar cell module 4 installed on the roof. .

  Furthermore, since the fixing member 3 is fixed within the above-described range with respect to the portion exposed on the surface of one roofing material 2, this causes capillary action between the overlapping roofing materials 2. It is possible to prevent the occurrence of rain leakage by preventing it from occurring.

  The present invention has been described with reference to preferred embodiments. However, the present invention is not limited to these embodiments, and various modifications can be made without departing from the spirit of the present invention as described below.
