DETAILED DESCRIPTION OF THE INVENTION

[0009] Hereinafter, an exemplary embodiment of the present invention (hereinafter abbreviated as "the present embodiment") will be described in detail. The present invention is not limited to the present embodiment, and various modifications can be made within the scope of the gist of the present invention. In the present specification, the upper and lower limits of each numerical range can be combined arbitrarily.

[0010] Fig. 1 is an exploded perspective view showing an example of a solar panel mounting wall structure of the present invention. Fig. 2 is a side view showing an example in which the upper end of a solar panel is attached to a vertical furring strip via a first fixing bracket. Fig. 3 is a perspective view showing an example of a vertical furring strip. Fig. 4 is a side view showing an example of a solar panel. Fig. 5 is a perspective view showing an example of a first fixing bracket. In the figure, the left side of the drawing is the outdoor side, the right side of the drawing is the indoor side, the top side of the drawing is the upper side, and the bottom side of the drawing is the lower side.

[0011] The solar panel mounting wall structure 1 of the present invention comprises a plurality of panels 10 that are lockably mounted to a building frame (not shown), and a solar panel 100 that is mounted on the opposite side of the panel 10 from the building frame. Vertical furring strips 50 arranged in the vertical direction are fixed to the panel 10, and the solar power generation panel 100 is restrained to the vertical furring strips 50 at its upper end via a first fixing bracket and at its lower end via a second fixing bracket.

[0012] The photovoltaic panel mounting wall structure 1 of the present invention is characterized in that the restraining force of the first fixing metal fittings on the photovoltaic panel 100 is greater than the restraining force of the second fixing metal fittings on the photovoltaic panel 100. As a result, even if the panel 10 rocks, the lower part of the photovoltaic panel 100 can be displaced more than the upper part, and therefore the rocking behavior of the panel 10 is not hindered.

[0013] Specifically, the upper end of the solar panel 100 is restrained by the first fixing bracket to the vertical furring strip 50 so as to restrain movement out of the plane, restrain movement in the vertical and horizontal directions within the plane, and allow rotation within the plane, i.e., to act as a pin fulcrum. In addition, the lower end of the solar panel 100 is restrained to the vertical furring strip 50 by a second fixing bracket so as to restrain movement out of the plane and allow horizontal movement and rotational displacement within the plane, i.e., to act as a roller fulcrum.

[0014] As a result, even if the panel 10 rocks, the upper part of the solar panel 100 can rotate within the plane, and the lower part can move horizontally or rotate within the plane, so that the rocking behavior of the panel 10 is more reliably not hindered.

[0015] As a result, the photovoltaic panel mounting wall structure 1 of the present invention can more effectively reduce the load acting on the panel 10 and the photovoltaic panel 100 during an earthquake.

[0016] In this specification, restraint refers to the suppression of out-of-plane displacement and in-plane horizontal and vertical displacement. Examples of restraint include fixing with bolts, pressing with elastic pieces or claws attached to the fixing bracket, or clamping the bracket with a clip. In this way, horizontal displacement in the in-plane direction is prevented from occurring up to a certain stress, and vertical displacement is limited to a certain distance regardless of the load. Fixation includes direct fixation and indirect fixation (via a secondary piece, etc.).

[0017] In addition, in this specification, the terms "horizontal," "vertical," "right angle," "parallel," and "orthogonal" are not strictly defined in the mathematical sense, and allow for errors in design, manufacturing, and installation.

[0018] The panel 10 has at least a rectangular plate-shaped portion, and is embedded with fasteners 30 for fixing the panel 10 to a building frame (not shown) and fasteners 40 for fixing exterior materials for attaching a solar power generation panel 100 to the panel 10.

[0019] The panel 10 is not particularly limited, and inorganic panels generally used as building panels, such as lightweight aerated concrete panels and cement-based extrusion molding panels, can be used.

[0020] In the photovoltaic panel mounting wall structure 1 of this embodiment, the panel 10 is preferably an aerated concrete panel (ALC panel). By using ALC panels that have excellent fire resistance, it is possible to meet fire resistance standards without using highly fire-resistant materials for the exterior materials of the solar power generation panel 100 or the like.

[0021] An example of lightweight aerated concrete is ALC, as described in JIS A 5416. For example, lightweight aerated concrete is made of cement, calcareous raw materials, siliceous raw materials, and water as the main ingredients, and is composed of a hardened body with a bulk specific gravity of about 0.1 to 1.0 that has a large amount of air bubbles mixed in, and a reinforcing material embedded inside.

[0022] The panel 10 is a panel having at least a rectangular plate-shaped portion, and may be a rectangular flat panel. In the following embodiments, a rectangular flat panel will be described as an example of the panel 10. In addition, in the following description, when the terms "main surface," "long side direction," "short side direction," etc. are used with respect to the panel 10 and the solar power generation panel 100, they refer to the "main surface," "long side direction," "short side direction," etc. of the rectangular plate-shaped portion of the panel 10.

[0023] The size of the panel 10 is not particularly limited, but as an example, the panel 10 is a substantially rectangular plate with long sides of 1820 mm, short sides of 606 mm, and a thickness of 50 to 150 mm. However, dimensional errors in the design and manufacturing of the outer shape of the panel 10 are allowed.

[0024] Note that reinforcing materials such as steel bars, wire mesh, and metal wires (not shown) may be embedded inside the panel 10 to ensure strength. The surface of the panel 10 may be bare or painted.

[0025] In addition, when a panel 10 having a solar power generation panel 100 attached as an exterior material is adjacent to a panel 10 having no solar power generation panel 100 attached, it is preferable that the end faces on both sides of the panels be flat without forming any actual structure (unevenness), and further that the end face of the panel 10 adjacent to the panel 10 having the solar power generation panel 100 attached facing the panel 10 having the solar power generation panel 100 attached is also flat.

[0026] As a result, when a load due to the out-of-plane inertial force of the solar power generation panel 100 as an exterior material acts during wind load or an earthquake, and different deflections occur between the panel 10 with the solar power generation panel 100 attached and the panel 10 without the solar power generation panel 100 attached, the sliding is not hindered at the butting surfaces of the panels 10, and they can be locked appropriately.

[0027] Furthermore, it is preferable that the other end faces of the panel 10 have a solid structure (unevenness) formed thereon from the viewpoint of waterproofing and fire resistance.

[0028] In this embodiment, the panel 10 is described as being arranged vertically with the short side oriented horizontally and the long side oriented vertically, but this is not limited to this, and the panel may be arranged horizontally with the short side oriented vertically and the long side oriented horizontally. Furthermore, when the panel 10 is substantially square, the short side is to be read as the first side, and the long side is to be read as the second side perpendicular to the first side.

[0029] One of the main surfaces of panel 10, which faces indoors, has a fastener 30 for fixing to the building structure embedded therein for attaching panel 10 to the building structure, and the other main surface of panel 10, which faces outdoors, has a fastener 40 for fixing to the exterior material embedded therein for attaching a solar power generation panel 100 (non-structural component) to panel 10.

[0030] 6 is an enlarged vertical cross-sectional view of the exterior material fixing fastener 40. The frame fixing fastener 30 has almost the same configuration as the exterior material fixing fastener 40, so a description thereof will be omitted here.

[0031] A rod-shaped or tubular steel material 13 (anchor steel rod) is inserted into the long hole 11 from the end face of the panel 10, and a locking metal fitting 14 is inserted into the countersunk hole 12 from the photovoltaic panel 100 side of the panel 10. Inside the panel 10, the steel material 13 and the locking metal fitting 14 (exterior material locking metal fitting, main body locking metal fitting) are engaged with each other.

[0032] 7, this locking fitting 14 is composed of an O-nut 15 having an engagement hole 15a, a bolt 16, and a washer 17. The steel material 13 is engaged with the engagement hole 15a of the O-nut 15 inside the panel 10.

[0033] Here, in this specification, the fastener 40 for fixing exterior material refers to the exterior material retaining metal fittings 14 + steel material 13 (anchor steel rod), and the fastener 30 for fixing the main body refers to the main body retaining metal fittings 14 + steel material 13 (anchor steel rod).

[0034] The O-nuts 15 may be arranged and fixed to the reinforcing bars (main bars or horizontal bars) inside the panel 10 by welding or mechanically joining them.

[0035] The fasteners 30 for fixing to the building frame are fastened with mounting brackets for attaching the panel 10 to the building frame, and the fasteners 40 for fixing to the exterior material are fastened with base metal fittings 20 for attaching exterior materials such as the solar power generation panel 100 to the panel 10. These mounting brackets and base metal fittings 20 may be made up of multiple metal fittings.

[0036] The embedded positions of the fasteners 40 for fixing the exterior material (and thus the mounting positions of the base metal fittings 20) are arranged in the direction of the long side, approximately in the center of the short side of the panel 10. When the embedded positions of the fasteners 30 for fixing the main body are arranged in the center of the short side of the panel 10, both the panel 10 and the solar panel 100 become easier to lock, and earthquake resistance effects can be expected.

[0037] The base metal fitting 20 has an O-nut 15 embedded in the panel 10, a bolt 16 that screws onto the O-nut 15, a bolt portion 21b that is integral with the first base metal fitting 21, and a nut 23 that screws onto the bolt portion 21b. The bolt portion 21b is disposed approximately parallel to the bolt 16 in a side view.

[0038] The first base metal fitting 21 is disposed on the outdoor surface of the panel 10. The first base metal fitting 21 has an insertion hole (not shown) through which the bolt 16 is inserted, and the first base metal fitting 21 is attached to the panel 10 by threading the O-nut 15 into the bolt 16 through the insertion hole.

[0039] In the example shown in the figure, the cross-sectional shape of the first base metal fitting 21 is I-shaped (flat), but is not limited to this and may be, for example, L-shaped, U-shaped or rectangular.

[0040] The method of fastening the first base metal fitting 21 to the panel 10 is not limited as long as it can be fastened to the panel 10. For example, the first base metal fitting 21 may be fastened to the panel 10 by passing a locking metal fitting such as a bolt fixed to the panel 10 through the insertion hole, without using an O-nut 15. The first base metal fitting 21 may also be fastened directly to the panel 10 using a screw, a post-installed anchor, or the like.

[0041] An exterior material such as a photovoltaic panel 100 is fixed directly or indirectly to the second base metal fitting 22. The second base metal fitting 22 has an insertion hole (not shown) through which the bolt portion 21b is inserted, and the second base metal fitting 22 is attached to the first base metal fitting 21 by threading the bolt portion 21b into a nut 23 through the insertion hole. The second base metal fitting 22 is rotatable within the plane of the first base metal fitting 21, using the attachment axis to the first base metal fitting 21, i.e., the bolt portion 21b, as the rotation axis.

[0042] In the photovoltaic panel mounting wall structure 1 of this embodiment, the vertical furring strips 50 are made of so-called C-shaped steel (lip-shaped steel). Specifically, the vertical furring strip 50 is a long base material with a C-shaped cross section, which comprises a long base plate (flange portion) 51 that is long in one direction, a pair of side plates (web portions) 52, 52 that extend from both widthwise edges of the base plate 51 in the same direction perpendicular to the base plate 51, and a pair of opposing plates (lip portions) 53, 53 that extend from each extended end of the pair of side plates 52, 52 in a direction perpendicular to the side plates 52 and approaching each other, and face the base plate 51 approximately parallel to the base plate 51.

[0043] The vertical furring strips 50 are arranged with the lip portions 53, 53 facing the solar panel 100 side (outdoor side) and are attached to the second base metal fittings 22, for example, by welding or with bolts and nuts. In the example shown in Figures 1 and 2, the vertical furring strips 50 are attached to the second base metal fittings 22 at their flange portions 51 with bolt portions 21b and nuts 23.

[0044] In the example shown in Fig. 3, the cross-sectional shape of the vertical furring strips 50 is a C-shaped cross-section when viewed from above, but is not limited to this and may be, for example, a circular, square, L-shaped, H-shaped, U-shaped, or crank-shaped (Z-shaped) shape. For example, when the cross section is circular or square-shaped, round steel pipes or square steel pipes with a relatively thick plate thickness can be used. Furthermore, the vertical furring strips 50 may be channel steel other than C-shaped steel (lip steel). The vertical furring strips 50 may be attached directly to the first base metal fittings 21 or the panel 10 without using the second base metal fittings 22.

[0045] The solar panel 100 has, for example, a power generating cell between two glass plates. The number of glass plates may be one. Furthermore, the solar panel 100 may have a resin plate instead of a glass plate to reduce weight.

[0046] As shown in FIG. 4 , the solar panel 100 has a frame 110 made of metal or the like attached to its periphery. The frame 110 is attached, for example, by adhesive bonding, so as to grip the periphery of the solar panel 100. The frame 110 may be provided on at least a portion of the upper or lower edge of the solar panel 100. The frame 110 may be provided on the top, bottom, left, and right sides. The frame 110 has locking pieces 111, and is fastened to the vertical furring strips 50 at these locking pieces 111 via the first fixing bracket or the second fixing bracket. This fastens the solar panel 100 to the vertical furring strips 50.

[0047] In the example shown in FIG. 4, the locking piece 111 of the frame 110 on the upper end side of the solar panel 100 protrudes downward, and the locking piece 111 on the lower end side of the solar panel 100 protrudes upward. Furthermore, the locking piece 111 of the frame 110 disposed on the upper end side of the photovoltaic panel 100 is formed with a hole 111a through which a bolt is inserted. The photovoltaic panel 100 and frame 110 may be provided as a pre-assembled unit, or may be provided as separate units and assembled on-site.

[0048] In this embodiment, the solar power generation panel 100 is described as being approximately rectangular and arranged in a so-called horizontal configuration with the short sides oriented vertically and the long sides oriented horizontally, but this is not limited to this and the solar power generation panel 100 may also be arranged in a so-called vertical configuration with the short sides oriented horizontally and the long sides oriented vertically. Furthermore, when the solar panel 100 is substantially square, the short side is to be read as the first side, and the long side is to be read as the second side that substantially intersects with the first side.

[0049] The size of the solar panel 100 is not particularly limited, but as an example, the solar panel 100 is a roughly rectangular plate with long sides of 2000 mm, short sides of 1000 mm, and a thickness of 3 to 20 mm. However, dimensional errors during design and manufacturing are allowed for the outer shape of the panel 10. As an example, the frame is a frame-like shape with a thickness of 30 to 60 mm.

[0050] This embodiment can also be applied to cases where exterior materials other than solar panels are attached. Exterior materials other than solar panels may be attached to the frame, or the exterior materials may be attached to the vertical furring strips without using a frame. This embodiment is preferably applied to exterior materials that suppress damage to the exterior materials when the panel rocks, and that would impair additional functions such as power generation due to damage. Therefore, it may be preferable to apply this embodiment to solar panels that use glass.

[0051] <How to install the solar panel on top> Next, a method for attaching the solar panel to the top will be described. (First embodiment) The upper end of the photovoltaic panel 100 is restrained by the vertical furring strip 50 via the frame 110 and the first fixing bracket 60 . As shown in Fig. 5, the first fixing metal fitting (lightning plate) 60 is formed by pressing a substantially rectangular flat steel material, etc. A step 61 is formed in the center. The step 61 may be inclined or may be at a right angle, etc. The first fixing bracket 60 has an attachment portion 62 that extends from the central portion to one side (across the step 61) and is bolted to the vertical furring strip 50, and a fixing portion 63 that extends to the other side and fixes (restrains) the solar panel 100. The attachment portion 62 is formed with a hole 62a through which the shank of the bolt 67a is inserted, and the fixing portion 63 is formed with a hole 63a through which the shank of the bolt 68a is inserted.

[0052] The first fixing bracket 60 is arranged with the fixing portion 63 on the upper side and the mounting portion 62 on the lower side, and is fixed to the vertical furring strip 50 at the mounting portion 62 by welding, bolts and nuts, etc. In the example shown in Fig. 2, the first fixing bracket 60 is fixed to the vertical furring strip 50 at the mounting portion 62 by bolts 67a and nuts 67b.

[0053] At this time, a washer 65 is arranged inside the vertical furring strip 50 so that the lip portions 53, 53 of the vertical furring strip 50 are sandwiched between the washer 65 and the first fixing bracket 60. The washer 65 has a substantially rectangular, flat washer body 66 and a hole 66a formed in the washer body 66 through which a bolt 67a for fixing the first fixing bracket 60 to the vertical furring strip 50 is inserted. The hole 62a of the mounting portion 62 of the first fixing metal fitting 60 and the hole 66a of the washer 65 are arranged to overlap each other.

[0054] Then, the first fixing bracket 60 is attached to the vertical furring strip 50 by inserting the tip of the bolt 67a through the hole 62a of the mounting portion 62 of the first fixing bracket 60 and the hole 66a of the washer 65 and threading it into the nut 67b.

[0055] The indoor surface of the locking piece 111 of the frame 110 arranged on the upper end side of the solar panel 100 is butted against the outdoor surface of the fixing portion 63 of the first fixing bracket 60, and the hole 63a of the fixing portion 63 is aligned with the hole 111a of the locking piece 111. The locking piece 111 is then fixed to the fixing portion 63 of the first fixing bracket 60 with a bolt 68a and a nut 68b (pin fixing). The bolt 68a may be inserted into the hole 63a of the fixing portion 63 from the indoor side and fastened, or may be inserted from the outdoor side and fastened. A member to improve sliding (rotation) may be provided between the locking piece 111 and the nut 68b. For example, a washer or the like may be provided.

[0056] As a result, the upper end of the photovoltaic panel 100 is restrained by the vertical furring strips 50 via the first fixing brackets 60 and the frame 110 .

[0057] The photovoltaic panel 100 does not necessarily have to be secured to the first fixing bracket 60 with a bolt. A protrusion may be provided on the indoor surface of the fixing portion 63, and the locking piece 111 may be inserted between the protrusion and the vertical furring strip 50, and the protrusion may clamp and press the locking piece 111 against the vertical furring strip 50 to secure the panel. In this case, no hole for inserting a bolt is required in the fixing portion 63. The fixing portion 63 may be bent from the step 61 toward the indoor side to make it easier to press, or the first fixing bracket 60 may be formed without forming the step 61.

[0058] Alternatively, the photovoltaic panel 100 may be positioned so that the power generating cell portion thereof does not overlap with the mounting position of the bolt 68a, and the photovoltaic panel 100 may have a hole at the upper end into which the bolt is inserted, and may be fixed to the fixing portion 63 of the first fixing bracket 60 with a bolt, nut, or the like. In this case, a washer 65 may be used as the first fixing bracket, and the photovoltaic panel 100 may be attached directly to the washer 65.

[0059] For example, if the solar panel 100 is made of a resin plate and has a hole at the upper end, it will be relatively light in weight, making it easy to install at the construction site, and the solar panel 100 can be attached to the fixing portion 63 of the first fixing bracket 60 with a simple structure.

[0060] In this way, the upper end of the solar power generation panel 100 is pinned with bolts, nuts, etc., so even if the panel 10 rocks due to an earthquake, for example, the upper end of the solar power generation panel 100 is restricted from moving vertically and horizontally within the plane, but can rotate within the plane, so the rocking of the panel 10 is not hindered and the load of seismic forces acting on the panel 10 and the solar power generation panel 100 can be reduced.

[0061] FIG. 8 is a side view showing another example in which the upper end of a solar panel is attached to a vertical furring strip via a first fixing metal fitting.

[0062] The first fixing bracket 60 has a shape with a step 61 formed therein, so that when the first fixing bracket 60 is attached to the vertical furring strip 50, as shown in the figure, a gap is formed between the lip portion 53 of the vertical furring strip 50 and the fixing portion 63 of the first fixing bracket 60.

[0063] The photovoltaic panel 100 is arranged so that the locking piece 111 of the frame 110 arranged on its upper end side is inserted into the gap between the lip portion 53 of the vertical furring strip 50 and the fixing portion 63 of the first fixing bracket 60, and the hole 63a of the fixing portion 63 and the hole 111a of the locking piece 111 overlap. The locking piece 111 is then fixed to the fixing portion 63 of the first fixing bracket 60 with a bolt 68a and a nut 68b (pin fixing). The bolt 68a may be inserted into the hole 63a of the fixing portion 63 from either the indoor side or the outdoor side and fastened.

[0064] As a result, the upper end of the photovoltaic panel 100 is restrained by the vertical furring strips 50 via the first fixing brackets 60 and the frame 110 .

[0065] Even in this case, the upper end of the solar power generation panel 100 is pinned with bolts, nuts, etc., so even if the panel 10 rocks due to an earthquake, for example, the upper end of the solar power generation panel 100 is restricted from moving vertically and horizontally within the plane, but can rotate within the plane, so the rocking of the panel 10 is not hindered and the load of seismic forces acting on the panel 10 and the solar power generation panel 100 can be reduced.

[0066] (Second embodiment) Next, a second embodiment of a method for attaching the photovoltaic power generation panel to the upper end will be described. Fig. 9 is a perspective view showing an example of a first fixing bracket in the second embodiment, and Fig. 10 is a side view showing the state in which the upper end of the solar panel is attached to the vertical furring strip via the first fixing bracket.

[0067] The first fixing metal fitting 70 is a square cylindrical member made of aluminum or the like, and has a slit portion 72 for holding the upper end portion of the photovoltaic panel 100. The first fixing bracket 70 has a rectangular cylindrical bracket body 71, a pair of slit portions 72 formed on each of two opposing sides of the bracket body 71, and a pair of elastic pieces 78 that open outward from the bracket body 71 as anti-protrusion portions. The first fixing bracket 70 has its bracket body 71 inserted between the pair of lip portions 53, 53 of the vertical furring strip 50, and is inserted while the pair of elastic pieces 78 are pressed by the pair of lip portions 53, and when the pair of elastic pieces 78 are inserted into the bracket body 71, the elastic pieces 78 are released from their pressed state and open, with the tips of the pair of elastic pieces 78 abutting against the inside of the pair of lip portions 53. In this way, the pair of elastic pieces 78 have a leaf spring mechanism, and by arranging the tips of the elastic pieces 78 abutting against the lip portions 53, the first fixing bracket 70 can be prevented from slipping out of the plane from the inside of the vertical furring strip 50. In addition, instead of the elastic piece 78, the anti-protrusion portion may be provided with a locking portion extending from the indoor surface of the fixture body 71 of the first fixing fixture 70 toward the indoor side, and the locking portion may be engaged with a hole provided in the base plate 51 of the vertical furring strip 50, thereby preventing the first fixing fixture 70 from moving outdoors.

[0068] At this time, a pair of washers 75, 75 are arranged below the first fixing metal fitting 70 so as to sandwich the lip portions 53, 53 of the vertical furring strip 50 therebetween. The washer 75 has a roughly rectangular, flat washer body 76 and a hole 76a formed in the washer body 76 through which a bolt 77a is inserted to fix the first fixing bracket 70 to the vertical furring strip 50, and the holes 75a, 75a of the pair of washers 75, 75 are arranged so as to overlap.

[0069] Then, the pair of washers 75, 75 are attached to the vertical furring strip 50 by inserting the tip of the bolt 77a into the hole 75a of the washer 75 and screwing it into the nut 77b. The first fixing bracket 70 is sandwiched between the pair of lip portions 53, 53, and is fixed in place while being placed on a pair of washers 75, 75. In this way, the first fixing bracket 70 placed on the washers 75 bears the load of the solar panel 100.

[0070] The photovoltaic panel 100 is arranged so that the locking piece 111 of the frame 110 arranged on its upper end side is sandwiched between the slit portion 72 of the first fixing bracket 70. By arranging the locking piece 111 of the frame 110 so that it is sandwiched between the slit portion 72 of the first fixing bracket 70, out-of-plane movement of the frame 110 is suppressed while allowing movement in the horizontal direction within the plane. The hole 71a of the fixing bracket main body 71 and the hole 111a of the locking piece 111 are arranged to overlap. The locking piece 111 is then fixed to the fixing bracket main body 71 of the first fixing bracket 70 with a bolt 73a and a nut 73b (pin fixing).

[0071] As a result, the upper end of the photovoltaic panel 100 is restrained by the vertical furring strip 50 via the first fixing bracket 70 and the frame 110.

[0072] The locking pieces 111 of the frame 110 are not limited to being fixed to the first fixing bracket 70 with bolts. An elastic piece may be provided from the indoor surface (vertical furring strip side) of the bracket body 71 of the first fixing bracket 70 toward the outdoor side, and when the locking pieces 111 are inserted into the slits 72, the elastic piece presses the locking pieces 111 toward the outdoor side, thereby preventing the frame 110 from moving out of the plane and in the horizontal and vertical directions within the plane.

[0073] In this way, the upper end of the solar power generation panel 100 is pinned with bolts, nuts, etc., so even if the panel 10 rocks due to an earthquake, for example, the upper end of the solar power generation panel 100 is restricted from moving vertically and horizontally within the plane, but can rotate within the plane, so the rocking of the panel 10 is not hindered and the load of seismic forces acting on the panel 10 and the solar power generation panel 100 can be reduced.

[0074] FIG. 11 is a side view showing another example in which the upper end of a photovoltaic panel is attached to a vertical furring strip via a first fixing metal fitting.

[0075] The indoor surface of the locking piece 111 of the frame 110 arranged on the upper end side of the solar panel 100 is butted against the outdoor surface of the metal fitting body 71 of the first fixing bracket 70, and the holes 71a of the metal fitting body 71 and the holes 111a of the locking piece 111 are arranged to overlap. Then, the locking piece 111 is fixed to the metal fitting body 71 of the first fixing bracket 70 with a bolt 73a and a nut 73b (pin fixing).

[0076] As a result, the upper end of the photovoltaic panel 100 is restrained by the vertical furring strip 50 via the first fixing bracket 70 and the frame 110.

[0077] Even in this case, the upper end of the solar power generation panel 100 is pinned with bolts, nuts, etc., so even if the panel 10 rocks due to an earthquake, for example, the upper end of the solar power generation panel 100 is restricted from moving vertically and horizontally within the plane, but can rotate within the plane, so the rocking of the panel 10 is not hindered and the load of seismic forces acting on the panel 10 and the solar power generation panel 100 can be reduced.

[0078] <How to install the bottom of the solar panel> Next, a method for attaching the solar panel to the lower end will be described. (First embodiment) Fig. 12 is a perspective view showing an example of a second fixing bracket in the first embodiment, and Fig. 13 is a side view showing a state in which the lower end of the solar panel is attached to a vertical furring strip via the second fixing bracket.

[0079] As shown in Figures 12 and 13, the second fixing bracket (lightning plate) 80 has a step 81 formed in the center by, for example, pressing a substantially rectangular flat steel plate. One side of the step 81 in the second fixing bracket 80 is an attachment section 82 that is bolted to the vertical furring strip 50, and the other side is a fixing section 83 that slides and fixes the solar panel 100. The attachment section 82 has a hole 82a through which the shank of a bolt 87a is inserted. Note that the attachment section 82 may be fixed to the vertical furring strip 50 by welding or the like, in addition to being fixed by a bolt and nut. Note that the second fixing bracket 80 does not necessarily have to have the step 81, as does the first fixing bracket 60.

[0080] In the example shown in Figure 12, the second fixing bracket 80 is arranged with the fixing portion 83 on the bottom and the mounting portion 82 on the top. In this way, the second fixing bracket 80 is attached upside down to the first fixing bracket 70. If the same fittings are used for the first fixing bracket 70 and the second fixing bracket 80, there is no need to go to the trouble of manufacturing fittings with different shapes, which can reduce the cost of manufacturing the fittings and may eliminate the need to increase the number of parts required for construction. The mounting portion 82 is fixed to the vertical furring strip 50 by welding, bolts, nuts, etc.

[0081] The second fixing bracket 80 has a shape with a step 81 formed therein, so that when the second fixing bracket 80 is attached to the vertical furring strip 50, as shown in the figure, a gap is formed between the lip portion 53 of the vertical furring strip 50 and the fixing portion 83 of the second fixing bracket 80.

[0082] The photovoltaic panel 100 is arranged so that the locking piece 111 of the frame 110 arranged on its lower end side is inserted into the gap between the lip portion 53 of the vertical furring strip 50 and the fixing portion 83 of the second fixing bracket 80. This configuration prevents the frame 110 from moving in an out-of-plane direction and allows movement in a horizontal direction within the plane. Therefore, horizontal movement and rotational displacement within the plane of the photovoltaic panel 100 are allowed.

[0083] 13, the second fixing bracket 80 is arranged with the fixing portion 83 on the lower side and the mounting portion 82 on the lower side. The mounting portion 82 of the second fixing bracket 80 is fixed to the vertical furring strip 50 by a bolt 87a and a nut 87b.

[0084] At this time, a washer 85 is arranged inside the vertical furring strip 50 so that the lip portions 53, 53 of the vertical furring strip 50 are sandwiched between the washer 85 and the second fixing bracket 80. The washer 85 has a substantially rectangular, flat washer body 86 and a hole 86a formed in the washer body 86 through which a bolt 87a for fixing the second fixing metal fitting 80 to the vertical furring strip 50 is inserted. The second fixing metal fitting 80 is arranged so that the hole 82a of the mounting portion 82 and the hole 86a of the washer 85 overlap each other.

[0085] Then, the second fixing bracket 80 is attached to the vertical furring strip 50 by inserting the tip of the bolt 87a through the hole 82a of the mounting portion 82 of the second fixing bracket 80 and the hole 86a of the washer 85 and threading it into the nut 87b.

[0086] The indoor surface of the locking piece 111 of the frame 110 arranged on the lower end side of the photovoltaic panel 100 and the outdoor surface of the fixing part 83 of the second fixing metal fitting 80 are butted together. The overlapping portion of the locking piece 111 of the frame 110 and the fixing portion 83 of the second fixing metal fitting 80 is then clamped and restrained by a clip member 120.

[0087] As shown in Figure 14, the clip member 120 is made of metal, resin, etc., and is a member with a U-shaped cross section in which a clip main body 121 is provided with a pair of gripping pieces 122, 122 protruding in the same direction from the ends of the clip main body 121.

[0088] As shown in Figure 13, the clip body 121 is abutted against the abutment portion between the locking piece 111 of the frame 110 and the fixed portion 83 of the second fixing bracket 80, and one of the gripping pieces 122 is clamped so that it abuts against the outdoor surface of the locking piece 111 and the other gripping piece 122 is clamped against the indoor surface of the fixed portion 83, so that the locking piece 111 of the frame 110 and the fixed portion 83 of the second fixing bracket 80 are clamped by the clip member 120 and restrained to each other.

[0089] At this time, by constructing at least the inner surface of the clip member 120 from a material with high slidability, the second fixing metal fitting 80 and the frame 110 become slidable.

[0090] This allows the lower end of the solar panel 100 to be slidably restrained to the vertical furring strip 50 via the frame 110 and the second fixing bracket 80, while ensuring resistance to earthquake forces, wind pressure, material warping, etc., and preventing rotational displacement (movement) and distortion of the solar panel 100 in an out-of-plane direction.

[0091] In this way, the lower part of the solar power generation panel 100 is slidably clamped by the clip member 120 between the locking piece 111 of the frame 110 and the fixing portion 83 of the second fixing bracket 80, rather than being fixed with a bolt, or is simply clamped between the fixing portion 83 of the second fixing bracket 80 and the vertical furring strip 50.Therefore, even if the panel 10 is rocked due to an earthquake, for example, the lower part of the solar power generation panel 100 can slide horizontally within the plane, so the rocking of the panel 10 is not hindered and the seismic force load on the panel 10 and the solar power generation panel 100 can be reduced.

[0092] As with the attachment of the upper end of the solar power generation panel 100, the lower end of the solar power generation panel 100 can also be attached by positioning the solar power generation cell portion of the solar power generation panel 100 so that it does not overlap with the bolt attachment position, and fastening the solar power generation panel 100, which has holes for inserting bolts at its lower end, to the second fixing bracket 80 with bolts, nuts, etc. In this case, a washer 85 can be used as the second fixing bracket, and the solar power generation panel 100 can be attached directly to the washer 85. In this case, if the holes for inserting the bolts of the second fixing bracket 80 or the washer 85 are long in the horizontal direction, horizontal movement can be more easily tolerated. The advantages of using a solar power generation panel 100 formed from a resin plate are the same as those described for the upper end.

[0093] FIG. 15 is a side view showing another example in which the lower end of a solar panel is attached to a vertical furring strip via a second fixing metal fitting.

[0094] The lower end of the solar panel 100 is inserted into the gap between the lip portion 53 of the vertical furring strip 50 and the fixing portion 83 of the second fixing metal fitting 80 and is restrained so as to be able to slide.

[0095] The lower frame 110 of the solar power generation panel 100 may not have a locking piece 111, or the lower end of the solar power generation panel 100 may be directly inserted into the gap formed between the lip portion 53 of the vertical furring strip 50 and the fixing portion 83 of the second fixing bracket 80.

[0096] Even in this case, the lower end of the solar power generation panel 100 is simply inserted into the gap between the vertical furring strip 50 and the second fixing bracket 80. Therefore, even if the panel 10 rocks due to an earthquake or the like, the lower part of the solar power generation panel 100 can slide horizontally within the plane, so the rocking of the panel 10 is not hindered and the seismic force load on the panel 10 and the solar power generation panel 100 can be reduced.

[0097] Second Embodiment Next, a second embodiment of a method for attaching the solar power generation panel to the lower end will be described. Fig. 16 is a perspective view showing an example of a second fixing bracket in the second embodiment. Fig. 17 is a side view showing the state in which the lower end of the solar power generation panel is attached to the vertical furring strip via the second fixing bracket.

[0098] The second fixing metal fitting 90 is made of aluminum or the like and has a rectangular cylindrical shape, and has a slit portion 92 for fixing the lower end portion of the photovoltaic panel 100 thereto. The second fixing bracket 90 has a bracket main body 91 having a square cylindrical shape, a pair of slit portions 92 formed on two opposing sides of the bracket main body 91, into which the lower end portion of the solar power generation panel 100 is inserted, and a pair of elastic pieces 98 that open outward from the bracket main body 91 as a jump-out prevention portion.

[0099] The second fixing bracket 90 has its fixing body 91 inserted between a pair of lip portions 53, 53 of the vertical furring strip 50, and is inserted while a pair of elastic pieces 98 are pressed by the pair of lip portions 53. When the pair of elastic pieces 98 are inserted into the fixing body 91, the elastic pieces 98 are released from their pressed state and open, with the tips of the pair of elastic pieces 98 abutting against the inside of the pair of lip portions 53. By arranging the tips of the pair of elastic pieces 98 abutting against the lip portions 53 in this way, the second fixing bracket 90 can be prevented from slipping out of the plane from the inside of the vertical furring strip 50. As with the first fixing bracket 70, a locking portion provided on the second fixing bracket 90 may be locked into a hole provided in the vertical furring strip 50 to prevent movement in the out-of-plane direction.

[0100] In the example shown in Figure 16, the second fixing bracket 90 is attached upside down to the first fixing bracket 70. If the same metal fittings are used for the second fixing bracket 90 and the first fixing bracket 70, there is no need to go to the trouble of manufacturing metal fittings with different shapes, which can reduce the cost of manufacturing the fittings and may eliminate the need to increase the number of parts required for installation.

[0101] At this time, a pair of washers 95, 95 are arranged below the second fixing metal fitting 90 so as to sandwich the lip portions 53, 53 of the vertical furring strip 50 therebetween. The washer 95 has a substantially rectangular, flat washer body 96 and a hole 96a formed in the washer body 96 through which a bolt 97a for fixing the second fixing bracket 90 to the vertical furring strip 50 is inserted, and the holes 96a, 96a of the pair of washers 95, 95 are arranged so as to overlap.

[0102] Then, the pair of washers 95, 95 are attached to the vertical furring strip 50 by inserting the tip of the bolt 97a into the hole 96a of the washer 95 and threading it into the nut 97b. The second fixing metal fitting 90 is sandwiched between the pair of lip portions 53, 53 and is fixed in place on a pair of washers 95, 95.

[0103] Note that if the second fixing bracket 90 is provided with a mechanism to prevent vertical movement, such as by being firmly clamped by the lip portion 53 of the vertical furring strip 50, and vertical movement can be restricted, then the washer 95 does not have to be provided. For example, elastic tabs may be provided on the back surface of the lip portion 53 or on the surface of the bracket body 91, or unevenness may be provided to restrict vertical movement.

[0104] The lower end of the solar panel 100 is inserted into the slit 92 of the second fixing metal fitting 90 and is slidably restrained. As shown in FIG. 17, the lower frame 110 of the solar panel 100 may not have a locking piece 111, or the lower end of the solar panel 100 may be inserted directly into the slit portion 92 of the second fixing bracket 90.

[0105] Since the lower part of the solar power generation panel 100 is simply inserted into the slit portion 92 of the second fixing bracket 90, even if the panel 10 rocks due to an earthquake or the like, the lower part of the solar power generation panel 100 can slide horizontally in-plane, so the rocking of the panel 10 is not hindered and the seismic force load on the panel 10 and the solar power generation panel 100 can be reduced.

[0106] Elastic claws 93 may be provided on the inside of the metal fitting body 91. By inserting the solar panel 100 into the slit portion 92 against the elastic force of the claws 93, the solar panel 100 can be more securely restrained by the elastic force of the claws 93.

[0107] FIG. 18 is a side view showing another example in which the lower end of a photovoltaic panel is attached to a vertical furring strip via a second fixing metal fitting. The indoor surface of the locking piece 111 of the frame 110 arranged on the lower end side of the solar panel 100 and the outdoor surface of the metal fitting body 91 of the second fixing metal fitting 90 are butted together. The overlapping portion of the locking piece 111 of the frame 110 and the metal fitting body 91 of the second fixing metal fitting 90 is then clamped and restrained by a clip member 120.

[0108] This allows the lower part of the solar panel 100 to be slidably restrained to the vertical furring strip 50 via the frame 110 and the second fixing bracket 90, while ensuring resistance to earthquake forces, wind pressure, warping of the material, etc., and preventing rotational displacement (movement) and distortion of the solar panel 100 in an out-of-plane direction.

[0109] Even in this case, the lower part of the solar power generation panel 100 is simply slidably clamped by the clip member 120 between the locking piece 111 of the frame 110 and the fitting body 91 of the second fixing fitting 90, rather than being fixed with a bolt. Therefore, even if the panel 10 is locked due to an earthquake, for example, the lower part of the solar power generation panel 100 can slide horizontally within the plane, so the locking of the panel 10 is not hindered and the seismic force load on the panel 10 and the solar power generation panel 100 can be reduced.

[0110] In the above-described embodiment, the washer is made of a metal plate, but the washer is not limited to a metal plate, and may be made of other materials such as hard rubber, plastic, etc. Also, a combination of these materials may be used.

[0111] Furthermore, in the above-described embodiment, an example was given in which the panels were arranged vertically and the solar power generation panels were arranged horizontally, but the present invention is not limited to this. For example, the panels may be arranged horizontally and the solar power generation panels may be arranged horizontally, or the panels may be arranged vertically and the solar power generation panels may be arranged vertically, or the panels may be arranged horizontally and the solar power generation panels may be arranged vertically. Furthermore, the panel arrangement (vertical, horizontal) and the solar power generation panel arrangement (vertical, horizontal) can be combined as appropriate.

[0112] In addition, in the above-described embodiment, an example was given in which the solar panel is restrained at multiple points on the top, but this is not limited to this, and it may also be restrained at one point near the center of the top.

[0113] Furthermore, in the above-described embodiment, a case has been described in which a frame is attached to the outer periphery of the solar power generation panel, but this is not limited to this, and it is also possible that a frame is not attached to the outer periphery of the solar power generation panel.

[0114] In addition, the manner in which the solar panel is restrained to the furring strip can be any combination of several forms in which the upper end is fixed and several forms in which the lower end is restrained, as described above.

[0115] The present invention also includes a building equipped with the solar panel mounting wall structure 1 of the present invention. In the building of the present invention, the solar panels do not interfere with the rocking of the panels, and the load of seismic force on the panels and the solar panels can be reduced.

[0116] In the solar panel mounting wall structure according to the present invention and in a building equipped with the solar panel mounting wall structure, by using ALC panels, which are recognized as fire-resistant exterior walls as exemplified in the notice regarding fire-resistant structures of buildings, as the panels on which the solar panels are mounted, the performance required for each structure can be maintained even when solar panels are installed on the surface of the exterior wall (related notices: Building Notices No. 1359 and 1362 of May 24, 2000, No. 1399 of May 30, and No. 1432 of May 31). (Reference: "Explanation of Fire Evacuation Regulations for Buildings 2016," edited by the Japan Building Administration Council, published by Gyosei Co., Ltd., page 14).

[0117] Although the embodiment of the present invention has been described above, the present invention is not limited to this and can be modified as appropriate within the scope of the invention. The present invention is widely applicable to wall structures using the rocking construction method in which solar panels are attached to the panels. [Industrial Applicability]

[0118] By using the solar panel mounting wall structure according to the present invention, exterior materials such as solar panels do not hinder the rocking of the panels, and deformation and damage to solar panels etc. are suppressed, making it possible to widely use the solar panel mounting wall structure in buildings.
