Description

[Technical Field]

[0001] This invention relates to a mounting structure for mounting a solar module (a solar panel) on the roof of a building. [Background technology]

[0002] Conventionally, solar modules have a frame (periphery frame) made of metal or the like around the periphery, and when they are attached to a roof or the like, the frame is held down with metal fittings or the like. However, in recent years, solar modules without such peripheral frames have begun to become popular. Solar modules without peripheral frames are expected to meet expanding needs, as they are lightweight and flexible, allowing them to be installed on curved surfaces. However, since peripheral frames cannot be used for fixing, some ingenuity is required for installation.

[0003] The following Patent Document 1 describes a method for installing a solar module that does not have a peripheral frame as described above. That is, the back surface of the solar module body is attached to the top surface of a long support frame with an adhesive, and the support frame is fixed to a support member using a fixing bolt (shown in the center of the figure, attached with the head facing downwards) or the like, as shown in Figure 9.

[0004] [Patent Document 1] Japanese Patent Application Laid-Open No. 2016-25755 Summary of the Invention [Problem to be solved by the invention]

[0005] The mounting structure described in Patent Document 1 makes it possible to firmly fix and mount a solar module that does not have a peripheral frame. Moreover, because the peripheral portion is not pressed down, there is no risk of damaging the light-receiving surface of the module. However, this mounting structure is not suitable for installing solar modules on roofs. When the support frame with the attached solar module is fixed to the support member with fixing bolts, as shown in Figure 9, the fixing bolts must be operated and tightened from below the solar module. However, when installing on a roof, there is usually no space for workers to insert their bodies or hands between the roof surface and the solar module that is attached to cover it. Even when trying to remove the solar module and its support frame from the roof for various maintenance purposes, this structure makes it extremely difficult to operate the fixing bolts.

[0006] The solar module is then installed on the roof, and the roof is then retracted. This allows the solar module to be easily removed from the roof for maintenance, etc. [Means for solving the problem]

[0007] The solar module is mounted on a roofing material (roof of a building) without a frame on the periphery. The solar module is placed on the upper surface of the upper flange of a plurality of guide rails having a substantially I-shaped cross section (including a substantially H-shaped cross section with flange portions positioned above and below), and is attached with an adhesive. and the lower flange of the guide rail is adapted to be fastened to the roof material or to a support member fixed to the roof material by a screw (i.e., a bolt or a nut) operated from above. Yo It is fixed with a clamp that is fastened by It is characterized by: An example is shown in Figures 4(a) to (d), etc. A guide rail 6 (6A-6B) having a substantially I-shaped (or substantially H-shaped) cross section is fixed onto a support member 3 fixed to a roofing material 2 by pressing a lower flange 6n with a clamping bracket 4 (4A-4B), and a solar module 1 is attached to the upper surface of an upper flange 6m of the guide rail 6 with adhesive 8. The clamping bracket 4 for fixing the lower flange 6n of the guide rail 6 is fastened and fixed to the support member 3 with a nut (screw) 5 attached so that it can be operated and tightened from above. Note that it is not essential to use a support member 3 as shown in the figure; the guide rail 6 (lower flange 6n) can also be fixed by fastening a clamping bracket directly to the roofing material 2 with a screw.

[0008] In the mounting structure of the above device, the solar module is attached with adhesive to the upper surface of the upper flange of the guide rail, which has a cross section of approximately I-shape (H-shape; the same applies below). Therefore, even if the solar module does not have an outer frame, its light-receiving surface is not damaged and it is reliably fixed to the guide rail. The guide rail's lower flange is secured to the roofing material or a support member secured to the roofing material by a clamp fastened with a screw. In other words, the guide rail is secured by pinching the lower flange between the clamp, which is held down by the force of the screw, and the roofing material or the support member. Because the screws are tightened from above, there is no need for workers to enter between the solar module and the roof or reach into the narrow gap between them. Whether before or after attaching the solar modules to the guide rail, workers can easily tighten or loosen the screws to secure or remove the guide rail from above (i.e., from the surface of the solar module) by reaching near the edge of each solar module or between adjacent solar modules.

[0009] Regarding the mounting structure of the above idea, The roof material is a folded-plate roof material with a seam (a streak-like protrusion) at the top, and the support member is fixed to the roof material by clamping the seam from both the left and right sides, and the lower flange of the guide rail is fixed by being clamped between the clamping metal fitting fastened with the screw and the support member. It is even more preferable if the above-mentioned structure is adopted. The examples shown in Figures 4(a) to 4(d) are configured in this manner. Reference numeral 2a denotes the seam portion, and reference numeral 3 denotes the support member.

[0010] As mentioned above, it is possible to fasten the lower flange of the guide rail with a clamp that is directly fastened to the roofing material by a screw operated from above. However, in this case, the roofing material must be specially designed to be able to connect with the screw. This may require modifying the roof or welding additional components to the roof. In this regard, it is advantageous to use folded-plate roofing materials for the roof, fix the support members to the roofing materials by clamping the seams, and fix the lower flange of the guide rail to the support members with clamps and the screws. In this way, the support members can be attached to the roof without any special processing, and the guide rails and solar modules can be placed on top of them. Furthermore, when removing the solar modules, the guide rails and modules can be removed along with the support members and returned to the roof as they were.

[0011] In the mounting structure of the above invention, it is even more preferable that a protrusion or groove extending in the length direction of the guide rail is formed on the upper surface of the lower flange of the guide rail, and that a recess or protrusion that engages with the protrusion or groove of the guide rail is formed on the lower surface of the clamping fixture. 4(a) to 4(d) show examples. A protrusion 6x is formed on the upper surface of the lower flange 6n of the guide rail 6 (6A / 6B), and a recess 4x into which the protrusion 6x of the guide rail fits is formed on the lower surface of the pressing fitting 4 (4A / 4B), and the protrusion 6x and recess 4x mesh with each other. In this way, when the guide rail and the clamping member both have meshing portions, the guide rail is fixed by the clamping member very reliably, and in particular, the widthwise position of the guide rail is prevented from unexpectedly shifting.

[0012] In the mounting structure of the above invention, in the guide rail on which the entire length of one edge of the solar module (i.e., the edge that is one side of the outer periphery) is placed, it is particularly preferable that the upper flange has an upper surface portion (approximately horizontal flat portion) to which the underside near the one edge is adhered, as well as an upward protrusion that allows the outermost edge of the one edge to be attached to position the solar module. An example is shown in Figures 4(b) and (c). An upward protrusion 6p is formed on one edge of the upper surface of the upper flange 6m of the guide rail 6B. When attaching the solar module 1 with adhesive 8, the edge of the solar module 1 is brought into contact with this upward protrusion 6p, as shown in Figure 8(b), to accurately determine its position. In this way, if an upward protrusion is formed on the upper flange of some of the guide rails (i.e., the guide rails on which the entire length of one edge of the solar module is placed), it becomes possible to accurately and easily position the solar module when attaching it.

[0013] In the above mounting structure, it is further preferable that a position-adjustable protruding member is attached to at least some of the multiple guide rails, protruding to a position higher than the upper surface of the upper flange of the guide rail and being fixed in position in the longitudinal direction of the guide rail, thereby enabling positioning of the solar module by aligning another edge that is not parallel to the one edge of the solar module (the edge whose entire length is placed on the guide rail). An example is shown in Figures 7(c) and 8(b) (see the detailed view of the drawer). A position-adjustable protruding member 7 is attached to the side of the guide rail 6A using a bolt 7d or the like. A portion of the protruding member 7 protrudes to a position higher than the top surface of the upper flange 6m of the guide rail 6A, and its position can be adjusted along the length of the guide rail 6A. When the above-described variable-position protruding member is attached to the guide rail at an appropriate position, a portion of the protruding member protrudes above the upper surface of the upper flange of the guide rail. By fitting one edge of the solar module (the other edge described above) to the protruding portion, it becomes possible to position the solar module. Since the solar module is attached to the upper surface of the upper flange of the guide rail with an adhesive and it is difficult to adjust its position after attachment, it is advantageous to use the above-described upward protruding portion and this variable-position protruding member to facilitate positioning. [Effects of the Invention]

[0014] In the solar module mounting structure proposed, a lightweight solar module without a peripheral frame is securely fixed to the roofing material via a guide rail, etc., without damaging the light-receiving surface. The guide rail is fixed with a clamp fastened by a screw operated from above, so the screw can be easily fastened and released, and therefore the guide rail can be easily fixed or removed even after the solar module is attached. Furthermore, if a folded-plate roofing material is used for the roof and the support members are fixed by clamping the seams, and the guide rails are fixed to the support members, the support members can be attached to the roof and solar modules can be placed without any special processing, and they can be easily restored when they are removed.

[0015] In the above mounting structure, if a protrusion or groove is formed on the upper surface of the lower flange of the guide rail and a recess or protrusion is formed on the lower surface of the clamping member, and the two are interlocked together, the guide rail can be fixed very securely by the clamping member. Furthermore, if an upward protrusion is formed on the upper flange along with a substantially horizontal upper surface portion relative to the guide rail on which the entire length of one edge of the solar module is placed, the solar module can be positioned accurately and easily. Furthermore, by attaching a position-variable protruding member to an appropriate position on at least some of the guide rails, the solar module can be positioned by fitting one edge of the solar module to the protruding portion. As described above, by providing the guide rail with an upward protrusion and attaching a position-variable protrusion member to the guide rail and using the same appropriately, it is possible to accurately position the solar module within a two-dimensional plane.

[0017] Hereinafter, an embodiment of the present invention will be introduced with reference to the drawings. Figures 1 and 2 show an overview of a state in which multiple solar modules 1 that do not have frames on the perimeter are attached to a roofing material 2. As shown in Figure 1, the solar modules 1 are arranged on the sloped roofing material 2 from the bottom (referred to as the "eaves side") to the top (referred to as the "ridge side") at intervals of several centimeters to several tens of centimeters. Furthermore, as shown in Figure 2, the solar modules 1 are attached to the roofing material 2 via multiple guide rails 6 arranged in parallel, and each guide rail 6 is fixed to the roofing material 2 by clamps 4 or the like.

[0018] As shown in Figure 3(a), the roofing material 2 is a corrugated sheet with a cross section of repeating trapezoidal steps, and is a folded-plate roofing material with a seam 2a at the top. The seam 2a is a double-round seam with a wide circular cross-section 2c above the neck 2b, and such seam 2a is formed continuously along the length of the roofing material 2. Note that instead of the double-round seam 2a shown in the figure, folded-plate roofing materials with other shapes of seam 2a can also be used, such as a half-round seam with a semicircular cross-section, a square seam with a triangular cross-section, or a cross-section with an inverted L-shape. Then, as shown in FIGS. 3(b) and 3(c), a guide rail 6 is fixed onto the roof material 2 using a support member 3, a clamp 4, and a nut 5.

[0019] The state in which the guide rail 6 is fixed by the support member 3, the pressing metal fittings 4, etc. is as shown in FIGS. 4(a) to 4(d), which are detailed views of parts A to D in FIGS. 3(b) and 3(c).

[0020] That is, first, as shown in Figure 4(a), support member 3 is attached to roofing material 2. Support member 3 consists of a pair of gripping pieces 3a and 3b, each with a roughly C-shaped cross section, fastened together with a bolt 3c and nut 3d. Bolt 3c is passed from below through a through-hole that passes through the overlapping upper parts of gripping pieces 3a and 3b to prevent rotation, and nut 3d is fitted onto the shank of the bolt and tightened. As the upper parts of gripping pieces 3a and 3b overlap more tightly, their lower ends move closer together until they touch. By clamping the seam 2a (neck 2b) of roofing material 2 with these approaching lower ends, support member 3 can be fixed to roofing material 2.

[0021] As shown in Figure 4(a), a guide rail 6 is placed on the support member 3 fixed as described above. A flat portion 3e is formed at the upper end of one of the gripping pieces 3a of the support member 3, and the guide rail 6 is placed on this flat portion 3e. The guide rails 6 (6A and 6B) are extruded aluminum alloy members with a roughly I-shaped cross section, as shown in Figure 4(b) and other figures.

[0022] To secure the guide rail 6 placed on the flat portion 3e of the support member 3, as shown in Figures 4(a) and 4(b), a one-sided presser bracket 4 (4A) is placed on the flat portion 3e and the lower flange 6n of the guide rail 6, and the presser bracket 4 is then pressed down by tightening a nut 5 that fits onto the bolt 3c of the support member 3 from above. A protrusion 6x is formed on the upper surface of the lower flange 6n, and a recess 4x is formed on the underside of one end of the presser bracket 4 to engage with the protrusion 6x. Therefore, when the nut 5 is tightened, the guide rail 6 (lower flange 6n) is sandwiched between the support member 3 and the presser bracket 4, and is firmly fixed in place.

[0023] As shown in Figure 4(b), the solar module 1 is attached to the guide rail 6 fixed to the roofing material 2 in the above manner using an adhesive 8. The upper flange 6m of the guide rail 6 has a substantially horizontal and flat upper surface portion, and the solar module 1 (underside) is attached to this by applying, for example, a silicone resin-based adhesive 8 thereon.

[0024] The installation state of the solar module 1 etc. shown in Figure 4(b) is part B in Figure 3(c), i.e., the edge part closest to the eaves of the solar module 1. Since this edge part is placed over its entire length on the guide rail 6B in Figure 4(b), an upward protrusion 6p extending in the length direction is formed on the end part of the upper surface part of the guide rail 6B closer to the eaves side as described above on the upper flange 6m of the guide rail 6B. The solar module 1 is properly positioned by placing the edge part closest to the eaves of the solar module 1 along this upward protrusion 6p on the upper surface part of the guide rail 6B.

[0025] The installation states of the solar module 1 and the like at parts C and D in FIG. 3(c) are shown in FIGS. 4(c) and 4(d), respectively. Figure 4(c) shows the fixed state of the ridge-side edge of the solar module 1 arranged on the eaves side and the eave-side edge of the solar module 1 arranged on the ridge side. The former (the edge shown on the left side of Figure 4(c)) is attached with an adhesive to the upper surface portion of the upper flange 6m of the guide rail 6A that does not have an upward protrusion, and the latter (the edge shown on the right side of Figure 4(c)) is adhered to the upper surface portion of the guide rail 6B that has an upward protrusion 6p, with its edge aligned along the upward protrusion 6p, as in Figure 4(b).

[0026] To secure the adjacent guide rails 6A and 6B shown on the left and right in Figure 4(c) to the support member 3, a double-sided clamping bracket 4B is attached midway between each guide rail 6A and 6B, pressing down on both lower flanges 6n. A nut 5 is fitted from above onto a bolt 3c that passes through the support member 3 and passes upward through the center of the clamping bracket 4B, and the clamping bracket 4B presses down both guide rails 6A and 6B onto the support member 3. As in the example in Figure 4(b), the protrusions 6x formed on the upper surface of the lower flanges 6n of each guide rail 6A and 6B engage with the recesses 4x formed on the underside of the clamping bracket 4B, so that the guide rails 6A and 6B are pressed down firmly onto the support member 3 by the clamping bracket 4B.

[0027] Figure 4(d) shows the installation state of each solar module 1 at a location that does not include the edge closest to the eaves of the module 1 (i.e., part D in Figure 3(c)). Because the edge closest to the eaves is not being placed, a guide rail 6A without an upward protrusion 6p is used. As in Figure 4(b), the guide rail 6A is pressed against the lower flange 6n by a one-sided pressing metal fitting 4A, and the protrusion 6x of the lower flange 6n is engaged with the recess 4x of the pressing metal fitting 4A to prevent misalignment. The solar module 1 is attached to the upper surface of the upper flange 6m of the guide rail 6A using adhesive 8.

[0028] The construction procedure for the mounting structure of the solar module 1 shown in FIGS. 1 to 4 will be described with reference to FIGS.

[0029] 5(a) is a perspective view of the aforementioned support member 3. A pair of opposing gripping pieces 3a and 3b, each having a roughly C-shaped cross section, are connected by a bolt 3c and a nut 3d, and a flat portion 3e is formed on the top of one of the gripping pieces 3a on which the guide rails 6 (6A and 6B) and the like are placed. The support member 3 is fixed to the appropriate locations on the roof material 2 (locations shown in Figures 2 and 3) as shown in Figure 5(b). That is, before tightening the bolt 3c and nut 3d, the gripping pieces 3a and 3b are opened and placed over the seam 2a of the roof material 2, and then the nut 3d is tightened onto the bolt 3c. This tightening force acts on the joint at the top of the gripping pieces 3a and 3b, causing the lower ends of the gripping pieces 3a and 3b to come together and clamp the neck 2b of the seam 2a.

[0030] As described above, the guide rails 6 are placed and fixed on the flat portions 3e of the support members 3 fixed to the respective locations of the roof material 2. For example, the guide rail 6 (guide rail 6B in FIG. 4(b)) placed closest to the eaves (the lowest part in FIG. 2) is fixed in the following manner. As shown in Figure 6(a), the guide rail 6B (lower flange 6n) is placed on the support member 3 (flat portion 3e) fixed to the roofing material 2, and then the clamp 4A and nut 5 are attached to the support member 3. The clamp 4A is attached so that the bolt 3c of the support member 3 passes through the through-hole near the center and one side of the clamp 4A overlaps the lower flange 6n of the guide rail 6B. The clamp 4A is then positioned and oriented so that the recess 4x on its underside engages with the ridge 6x on the upper surface of the lower flange 6n, as shown in Figure 6(b). A nut 5 is fitted onto the bolt 3c passed through the through-hole of the clamp 4A, and the nut 5 is then tightened from above using a drill driver 10. This allows the guide rail 6B to be firmly fixed to the support member 3 by the action of the nut 5 and the clamp 4A.

[0031] The second to fourth guide rails 6 from the bottom (guide rail 6A in FIG. 4(d)), following the guide rail 6 closest to the eaves in FIG. 2, are fixed onto the support member 3 as shown in FIG. 7(a). That is, the guide rail 6A is placed on the support member 3 fixed to the roofing material 2, and then a clamp 4A and nut 5 are attached to the support member 3. The bolt 3c of the support member 3 is passed through the through-hole near the center of the clamp 4A, and one side of the clamp 4A is positioned over the lower flange 6n of the guide rail 6A. The recess 4x on the underside of the clamp 4A engages with the protrusion 6x formed on the upper surface of the lower flange 6n. Next, the nut 5 is fitted onto the bolt 3c and tightened from above, thereby firmly fixing the guide rail 6B onto the support member 3 with the clamp 4A.

[0032] In locations where two solar modules 1 are adjacent to each other on the eaves and ridge sides, such as the vertical center of Figure 2, two closely spaced guide rails 6 (guide rails 6A and 6B in Figure 4(c)) are fixed to the support member 3 as shown in Figure 7(b). That is, the guide rails 6A and 6B are placed at a predetermined distance near both ends of the support member 3 fixed to the roofing material 2, and a clamping bracket 4B is attached in the middle between them. As shown in Figure 4(c), the clamping bracket 4B is a double-sided clamping type. The bolt 3c of the support member 3 is passed through the central through-hole, and the recesses 4x formed on the undersides of both sides are engaged with the protrusions 6x on the lower flanges 6n of the guide rails 6A and 6B on both sides. In this state, when the nut 5 is fitted onto the bolt 3c from above and tightened, the clamping bracket 4B can simultaneously press and fix the two guide rails 6A and 6B onto the support member 3.

[0033] The other four guide rails 6 (6A) for placing the ridge-side solar modules 1 on the upper side of Figure 2 are attached to the fixed support members 3 in the same manner as in Figure 7(a). By tightening nuts 5 from above onto the bolts 3c of the support members 3, the guide rails 6A are fixed in the state shown in Figure 4(d).

[0034] The position of each solar module 1 on the roofing material 2 shown in Fig. 2 in the vertical direction, i.e., toward the eaves side and ridge side, can be determined by the upward protrusions 6p of the guide rails 6B shown in Figs. 4(b) and 4(c) (or Figs. 6(a) and 7(b)). When placing the vicinity of the edge of the solar module 1 on the upper surface of the upper flange 6m of the guide rails 6B, the position of the solar module 1 in the above direction can be correctly determined by aligning the outermost edge (end) of the edge with the upward protrusions 6p.

[0035] 2 of each solar module 1, i.e., to determine the position of the edge perpendicular to the edge positioned by the guide rail 6B in Fig. 4(b) etc., protruding members 7 are attached to appropriate locations in the length direction of the guide rail 6A as shown in Fig. 7(c). The protruding members 7 are attached to the sides of each guide rail 6A, and when attached, their upper portions 7c protrude above the upper flanges 6m of the guide rail 6A.

[0036] As shown in the detailed view of the drawer in FIG. 7(c), the protruding member 7 has locking ends 7a and 7b on the main body for engaging with the guide rail 6A, and a fastening bolt 7d is inserted into a threaded hole that penetrates the main body. The locking ends 7a and 7b are inserted between the protrusion 6y formed on the underside of the upper flange 6m of the guide rail 6A and the protrusion 6x formed on the upper surface of the lower flange 6n of the guide rail 6A and the web of the guide rail 6A, respectively, so that the protruding member 7 is attached to the guide rail 6A and becomes movable along its length. After moving the protruding member 7 to an appropriate position for positioning the solar module 1, the locking bolt 7d is inserted and the tip is pressed against the web of the guide rail 6A, thereby fixing the position of the protruding member 7. The upper portion 7c that protrudes above the guide rail 6A can be used as a stopper to position the solar module 1 (see FIG. 8(b)).

[0037] As described above, after the guide rail 6 (6A / 6B) is attached to the appropriate location on the roofing material 2 using the support member 3, clamping bracket 4, nut 5, etc. and the protruding member 7 is fixed, adhesive (sealant) 8 is applied to the top surface of the guide rail 6 (upper flange 6m) using a caulking gun 11 as shown in Figure 8(a).

[0038] After applying the adhesive 8 and before it hardens, the solar module 1 is placed on the top surface of each guide rail 6 as shown in Figure 8(b). When placing the solar module 1, as described above, the upward protrusion 6p of the guide rail 6B and the protrusion member 7 of the guide rail 6A are used to position each solar module 1. With the solar module 1 placed in an appropriate position on each guide rail 6, it is advisable to attach the solar module 1 while pressing it with a pressure roller or the like.
