In addition, when a plurality of embodiments and modifications are included in the following, it is assumed from the beginning that these characteristic portions are used in appropriate combinations.

  Although the case where a solar cell module is installed in the metal roof where a roof material consists of a metal plate is demonstrated below, it is not limited to this. The present invention may be applied to other forms of roof such as slate tiles.

  FIG. 1 is a view showing a state in which a solar cell module (partially cut out) is attached to a roof using the solar cell module fixture fixing structure according to an embodiment of the present invention. .

  As shown in FIG. 1, a solar cell module 10 in which the fixing structure of the present embodiment is used is installed on a roof 100 by a long frame 12 to which a plurality of mount frames are connected and an anchor (attachment tool) 14. Is done. The long frame 12 is installed along the building direction of the roof 100.

  In FIG. 1, two gantry frames 12 a and 12 b are connected by a connecting member 16 to constitute one long frame 12. Thereby, a plurality of solar cell modules 10 can be installed side by side in the direction of the roof of the roof 100. However, the long frame 12 may be configured by only the gantry frame 12a or 12b so that one or two solar cell modules 10 can be installed.

  The solar cell module 10 includes a solar cell panel 18 in which a plurality of solar cell elements are sandwiched by protective members such as glass plates, and a module frame 20 (hereinafter simply referred to as “frame 20”) installed on the periphery of the panel. Have. The frame 20 protects the periphery of the solar cell panel 18 and also functions as a member for attaching the solar cell module 10 to the long frame 12.

  In the present embodiment, the solar cell module 10 is arranged on the long frame 12 so that the longitudinal direction of the solar cell module 10 having a substantially rectangular shape in plan view is substantially orthogonal to the longitudinal direction of the long frame 12. ing. The plurality of solar cell modules 10 are arranged so that, for example, the long sides and the short sides are substantially parallel to each other between adjacent modules. In the above description, “plan view” refers to a direction viewed from a direction perpendicular to the light receiving surface of the solar cell panel 18.

  The frame 20 preferably has a flange 22 along each long side. The flange 22 protrudes outward in the width direction of the frame 20 on the side opposite to the side on which the solar cell panel 18 is disposed. Moreover, the cross section cut | disconnected in the width direction of the flame | frame 20 has the substantially L shape, for example. The solar cell module 10 is fixed to the long frame 12 using the flange 22 by pressing the flange 22 with a pressing member 24 fixed to the frame 20 with a bolt.

  The long frame 12 is fixed to the anchor 14 so that the longitudinal direction thereof is along the direction of the roof of the roof 100. On the long frame 12, the frame 20 of the solar cell module 10 is placed and fixed. In the girder direction of the roof 100 (direction perpendicular to the building direction), a plurality of gantry frames 12a and 12b are arranged substantially parallel to each other with an appropriate interval. It is preferable to arrange two or more long frames 12 under one solar cell module 10.

  The anchor 14 is an attachment for installing the solar cell module 10 on the roof 100 via the long frame 12. The anchor 14 needs to have sufficient strength to support the weight of the solar cell module 10 and is preferably made of metal, for example.

  As shown in FIG. 2, the anchor 14 has a base plate 26 that is fixed to the roof, for example, in a rectangular shape in plan view, and a shaft portion 28 that is erected substantially perpendicular to the upper surface of the base plate 26. In the base plate 26, for example, insertion holes 27 are formed at four corners. Accordingly, the anchor 14 is fixed by inserting a fastening member such as a wood screw from the insertion hole 27 into the roof 100. Details of fixing the anchor 14 will be described later. Note that the position and number of the insertion holes 27 formed in the base plate 26 of the anchor 14 can be appropriately changed according to the shape, size, and the like of the base plate 26.

  The shaft portion 28 of the anchor 14 is a bolt having a thread on its outer periphery. A lower nut (not shown) is inserted into the shaft portion 28 while rotating, and a long hole 13 (see FIG. 1) formed in the long frame 12 is inserted into the shaft portion 28 protruding from the lower nut. . Then, an upper nut (not shown) is inserted into the shaft portion 28 while rotating the long frame 12 between the lower nut and the shaft. Thereby, the long frame 12 to which the solar cell module 10 is attached is fixed to the anchor 14.

  Next, a fixing structure of the anchor 14 (hereinafter simply referred to as “fixing structure” as appropriate) will be described. First, the conventional fixing structure will be described with reference to FIG. 3, and then the fixing structure 30 of the present embodiment will be described with reference to FIGS. 4 to 6.

  FIG. 3 is a view showing a state in which a large hole is formed in the waterproof sheet by a screw penetrating a gap between the rose plates in a roof having a field plate made of rose plates. As shown in FIG. 3, the roof 100 on which the solar cell module 10 is installed includes a field plate 102, a waterproof sheet 104 laid on the field plate 102, and a roof material 106 disposed on the waterproof sheet 104. It consists of and.

  The field board 102 is configured by arranging a large number of long rose boards fixed in the rafters with nails or the like along the girder direction in the building direction. In FIG. 3, only two loose plates 102a and 102b are shown, and a gap S having a width w is formed between them.

  The waterproof sheet 104 is for preventing water from entering the attic, and for example, asphalt roofing is preferably used. Further, the roof material 106 is formed by, for example, laying a large number of metal plates on the waterproof sheet 104. Each metal plate which comprises the roofing material 106 is connected so that peripheral parts may be wound, for example. For this reason, rainwater or the like cannot enter between the metal plates.

  The anchor 14 that is the above-described fixture for the solar cell module is installed on the surface of the roof material 106. A waterproof tape 32 is provided between the bottom surface of the base plate 26 and the surface of the roof material 106. For the water stop tape 32, for example, a conventionally known butyl tape having a water stop function and adhesiveness is suitably used. If butyl tape is attached in advance to the bottom surface of the base plate 26, the anchor 14 can be fixed efficiently. Thus, by providing the water stop tape 32 between the anchor 14 and the roof material 106, it is possible to effectively prevent rainwater and the like from entering between the two.

  The anchor 14 is fixed to the roof 100 by a fastening member 34. As the fastening member 34, for example, a wood screw with a sharp tip can be suitably used. The anchor 14 can be fixed to the roof 100 by inserting the fastening member 34 into the insertion hole 27 of the base plate 26 from above and screwing it into the field plate 102 through the roof material 106 and the waterproof sheet 104.

  A caulking agent 36 is placed around the head of the fastening member 34. By applying the caulking agent 36 in this way, it is preferable to prevent water from entering the insertion hole 27 of the base plate 26.

  When the anchor 14 is fixed to the roof 100 as described above, the screw portion of the fastening member 34 may be inserted into the gap S between the rose plates 102a and 102b constituting the field plate 102. In this case, when the fastening member 34 is screwed into the waterproof sheet 104 at a position corresponding to the gap S, the back surface of the portion through which the screw portion of the fastening member 34 passes is not supported by the loose plates 102a and 102b. As a result, a hole 103 larger than the screw portion of the fastening member 34 is formed in the waterproof sheet 104. In particular, when the width w of the gap S is increased due to drying contraction of the rose plates 102a and 102b or the waterproof sheet 104 is hard and brittle due to the passage of time since the construction of the house, the hole 103 is formed large. easy.

  When the large hole 103 is formed in the waterproof sheet 104 in this way, rainwater that has entered the gap 105 between the roofing material 106 and the waterproof sheet 104 and water generated by condensation in the gap 105 are transferred from the hole 103 to the attic. Intrusion into the water will cause problems of water leakage. Therefore, in the fixing structure of the present embodiment, the anchor 14 is fixed on the roof 100 so as not to impair the function of the waterproof sheet 104 as follows.

  FIG. 4 is a cross-sectional view taken along the line AA in FIG. 1, showing the fixing structure 30 of the present embodiment. Here, the same components as those described with reference to FIG. 3 are denoted by the same reference numerals, and redundant description will be omitted.

  As shown in FIG. 4, in the anchor fixing structure 30 of the present embodiment, the filling material 40 is arranged in the gap S between the rose plates 102 a and 102 b corresponding to the anchor fixing scheduled position on the roof material 106. In other words, the gap S between the bulk plates 102 a and 102 b is filled with the filling material 40. The stuffing material 40 can be composed of, for example, one or more combinations selected from a piece of wood, a caulking agent, a resin, a plastic, and rubber. The stuffing material 40 is preferably made of a hard material, but may be made of a relatively soft material such as rubber as long as the back surface of the waterproof sheet 104 can be supported while being stuffed in the gap S.

  FIG. 5 shows an example in which a piece of wood is used as the filling material 40. In this example, a material in which two pieces of wood 40a having a thickness t of about 2 mm and a height h of about 10 mm are overlapped is used as the stuffing material 40. The two pieces of wood 40a may be bonded together and then packed into the gap S, or may be simply stacked without bonding.

  Further, the length of the wood piece 40a is preferably set to a length that allows the wood piece 40a to be easily fitted into the gap S by cutting the wood piece 40a in accordance with the length of the gap S to be filled in the digit direction. Furthermore, you may stick the auxiliary | assistant piece 40b which has adhesiveness, such as a butyl tape, for example on the upper surface of the two laminated wood pieces 40a. The auxiliary piece 40b has a function of bonding the stacked wooden pieces 40a, a function of adjusting the difference in thickness between the rose plate 102a and the wooden piece 40a, or a function of bonding the wooden piece 40a and the waterproof sheet 104. Accordingly, it is possible to prevent water from entering the wooden piece 40a packed in the gap S along the shaft portion of the fastening member 34 and being immersed therein.

  By filling the gap S with the stuffing material 40 in this way, the back surface side of the waterproof sheet 104 is supported at the penetration position of the fastening member 34. When inserting the fastening member 34 while rotating, a through hole corresponding to the diameter of the shaft portion of the fastening member 34 is opened in the waterproof sheet 104, but a through hole having a size that is unlikely to cause water leakage is opened in the waterproof sheet 104. . Therefore, the waterproof sheet 104 can easily form a state in which the peripheral edge portion of the through hole is in close contact with the shaft portion of the fastening member 34. As a result, the waterproof sheet 104 can maintain the function of preventing water intrusion into the attic, and can prevent leakage of rainwater and the like.

  A reinforcing plate 44 made of, for example, plywood is provided on the lower surface side of the stuffing material 40 to support the stuffing material 40 from below. When the fastening member 34 is inserted into the stuffing material 40, the support of the stuffing material 40 can be made stronger, so that the base plate 26 of the anchor 14 can be firmly fixed to the base plate 102. As will be described later, the reinforcing member 44 may be inserted through the fastening member 34 while being pressed by an operator from the attic side, or fixed to the loose plates 102a and 102b adjacent to the gap S with screws 46. Also good. When the reinforcing plate 44 is fixed with the screw 46, the one having a length that penetrates the reinforcing plate 44 but does not penetrate the loose plates 102a and 102b is used.

  Furthermore, when a small gap remains between the filling material 40 and the loose plates 102a and 102b after the filling material 40 is packed in the gap S between the loose plates 102a and 102b, for example, as shown in FIG. A wedge-shaped auxiliary filling material 40c may be driven to fill the small gap. In this way, the stuffing material 40 is more tightly packed in the gap S, and the stuffing material 40 is prevented from falling down (ie, the attic side) when the fastening member 34 is inserted without providing the reinforcing plate 44. can do.

  Next, a procedure for fixing the anchor 14 in the anchor fixing structure 30 as described above will be described.

  The fixing work of the anchor 14 is performed jointly by two workers. First, a worker on the roof 100 (hereinafter referred to as a “rooftop worker”) uses a drill having a smaller diameter than the fastening member 34 at a position where the anchor is to be fixed on the roof material 106, and the roof material 106 and the waterproof sheet 104. In addition, a leading hole is formed through the loose plates 102a and 102b. At this time, the position of the tip hole is a position corresponding to one insertion hole 27 formed in the base plate 26 of the anchor 14.

  Another worker in the attic (hereinafter referred to as “attic worker”) confirms the drill position that has penetrated and estimates the position corresponding to the remaining insertion hole 27 with reference to the tip hole position. Mark. Since the formation position of the insertion hole is known depending on the type of the anchor 14 used for installing the solar cell module 10, it is possible to easily mark the positions of the remaining insertion holes 27 as described above. In this case, the outer contour (for example, a square) of the base plate 26 of the anchor 14 may be marked together.

  Subsequently, the attic worker checks whether or not the gap S between the loose plates adjacent to the marking portion is included. In this case, when a wood screw having a shaft diameter of, for example, 5 mm is used as the fastening member 34, the filling material 40 is inserted and temporarily fixed in the gap S having a width w of, for example, 4 mm or more. At this time, for example, there may be a case where temporary fixing cannot be performed only with the filling material 40 made of the piece of wood 40a as shown in FIG. In that case, what is necessary is just to pack in the clearance gap S so that it may be temporarily fixed using other packing material 40 from which thickness and material differ, or auxiliary packing material 40c shown in FIG.

  Next, the attic worker presses the reinforcing plate 44 against the rose plates 102a and 102b so that the marking portion is located at the approximate center of the reinforcing plate 44 on the opposite side of the roof material 106 of the rose plates 102a and 102b. In this state, give a voice signal to the worker on the roof. At this time, the reinforcing plate 44 may be fixed to the loose plates 102a and 102b with screws 46 as described above.

  Upon receiving the above signal, the worker on the roof surface inserts the fastening member (for example, wood screw) 34 into the insertion hole 27 of the base plate 26 of the anchor 14 toward the reinforcing plate 44 while rotating. Accordingly, the anchor 14 is fixed to the roof 100 by the fastening member (for example, wood screw) 34 penetrating to the reinforcing plate 44.

  As described above, according to the present embodiment, when the anchor 14 is fixed to the roof 100 composed of the field plate 102, the waterproof sheet 104, and the roof material 106 composed of the rose plates, the waterproofing function of the waterproof sheet 104. The anchor 14 can be fixed on the roofing material 106 without damaging it.

  Further, by providing the reinforcing plate 44 as described above, the anchor 14 can be firmly fixed to the roof 100 also by the fastening member 34 inserted through the filling material 40 in the gap S.

  FIG. 7 is a cross-sectional view taken along line AA in FIG. 1 showing a fixing structure 30 according to a modification of the present embodiment. Here, the same components as those described with reference to FIG.

  In the embodiment described with reference to FIG. 4, the reinforcing plate 44 is fixed to the loose plates 102 a and 102 b using screws 46. On the other hand, in the modification shown in FIG. 7, the reinforcing plate support member 110 is fixed to the rafter 108 to which the loose plates 102a and 102b are fixed using screws 112, and the reinforcing plate 44 is fixed to the loose plates 102a and 102b and the reinforcing plate support member. 4 and different from the embodiment shown in FIG. The rafter 108 is a columnar building material to which the field plate 102 such as the rose plate 102b is fixed. By fixing the reinforcing plate 44 using the reinforcing plate support member 110, the reinforcing plate 44 can be fixed more firmly. Specifically, by fixing the reinforcing plate 44 using the reinforcing plate support member 110, it is possible to increase resistance to a force applied in the insertion direction of the fastening member 34 called a compression load.

  Next, another fixing structure of the anchor 14 will be described. The fixing structure here is substantially the same as that shown in FIG. 7 except that the stuffing material provided in the gap between the loose plates is made of a sealing agent and the construction procedure is different. Therefore, the same components already described are denoted by the same reference numerals and redundant description is omitted. In addition, as the sealing agent, the same caulking agent 36 as described with reference to FIG. 4 around the head of the fastening member 34 may be used, or a different caulking agent or sealing agent may be used. .

  Next, with reference to FIGS. 8 to 11, a procedure for fixing the anchor 14 using a sealing agent as a stuffing material will be described. The work here can be performed by one person, unlike the above-described example, but it is preferable to perform the work by two or more persons. 8 shows the loose plates 102a and 102b to show the cross section in the building direction, while FIGS. 9 to 11 show the cross sections in the girder direction along the gap S between the loose plates 102a and 102b. The plates 102a and 102b are not shown.

  First, as shown in FIG. 8, the worker places the anchor 14 at a position where the anchor is to be fixed on the roof material 106 that constitutes the roof surface. In this state, the operator drills the front holes 50 by drilling through all the insertion holes 27 formed in the base plate 26 of the anchor 14. The front hole 50 is formed through the roof material 106, the waterproof sheet 104, and the rose plates 102a and 102b. Moreover, it is preferable to form the tip hole 50 in a hole having a smaller diameter than the screw diameter of the fastening member 34 used later. This is because if the leading hole 50 is formed to have a diameter equal to or larger than that of the fastening member 34, the anchor fixing force cannot be obtained.

  Subsequently, as shown in FIG. 9, the worker arranges the reinforcing plate 44 in correspondence with the formation position of the front hole 50 from the attic. The reinforcing plate 44 is attached in the same manner as described with reference to FIG. That is, the reinforcing plate 44 is covered by covering the position where the tip hole 50 is formed, and both ends of the reinforcing plate 44 extending to the vicinity of the rafter 108 are supported from below by the reinforcing plate support member 110 fixed to the rafter 108 with screws 112. And fix. At this time, it is preferable that the screw 112 is inserted into the reinforcing plate support member 110 and the rafter 108 while rotating so that the tip thereof is inclined about 10 degrees with respect to the back surface of the reinforcing plate 44. Accordingly, the reinforcing plate support member 110 is pressed against the reinforcing plate 44 by tightening the screws 112, and as a result, the reinforcing plate 44 can be more firmly fixed to the loose plates 102a and 102b.

  Subsequently, as shown in FIG. 10, the operator injects an appropriate amount of the sealing agent 52 into the front hole 50 from the roof surface. Thereby, the sealing agent 52 is filled in the gap S between the bulk plates 102a and 102b. Further, since the lower part of the gap S is blocked by the reinforcing plate 44, for example, the gel-like sealing agent 52 does not fall on the attic during injection. Here, before the reinforcing plate 44 is attached, a back-up material made of, for example, foamed polystyrene or the like is filled so as to fill the lower portion of the gap S from the attic, and the amount of the sealing agent 52 used is injected into the sealing agent 52 in that state. There is an advantage that can be reduced.

  Then, as shown in FIG. 11, the operator inserts the fastening member (for example, wood screw) 34 into the insertion hole 27 of the base plate 26 of the anchor 14 toward the reinforcing plate 44 while rotating. And the anchor 14 is fixed to the roof 100 because the fastening member 34 penetrates to the reinforcing plate 44. At this time, the sealing agent 52 that is filled in the tip hole 50 and is in a state before being completely cured enters the screw groove of the fastening member 34, so that the occurrence of water leakage through the fastening member 34 can be more reliably prevented. .

  As described above, the same effect as that of the fixing structure 30 can be obtained by the anchor fixing structure in this aspect. In other words, the sealing agent 52 is filled in the gap S between the rose plates 102a and 102b and the back surface side of the waterproof sheet 104 is supported. Therefore, the waterproof sheet 104 is formed with a through-hole having a diameter corresponding to the shaft portion of the fastening member 34 and a size that is unlikely to cause water leakage. Therefore, it becomes easy to form a state in which the peripheral edge portion of the through hole of the waterproof sheet 104 is in close contact with the shaft portion of the fastening member 34. As a result, the waterproof sheet 104 can maintain the function of preventing water intrusion into the attic, and can prevent leakage of rainwater and the like.

  In addition, the fixing structure and fixing method of the solar cell module fixture according to the present invention are not limited to the above-described embodiment and its modifications. It goes without saying that various changes and improvements may be made within the scope of matters described in the claims of the present application and equivalents thereof.
