Description

[Technical Field]

[0001] The present disclosure relates to a mounting member for supporting the load of solar panels on a flat roof. [Background technology]

[0002] A "flat roof" (pronounced "rikuyane" or "rokuyane") is a flat roof with no greater slope than a very gentle slope (known as a "water slope") for draining rainwater, etc. Flat roofs are more likely to retain rainwater than roofs with a steeper slope, so their top surface is often covered with waterproofing material. When installing an object (such as a solar panel) on a flat roof covered with waterproofing material, the object is sometimes placed on metal fittings (also known as a "dry foundation") that are erected in advance on the top surface of the flat roof to separate the object from the waterproofing material and prevent it from being damaged.

[0003] Furthermore, a wall-like structure called a "parapet" is often provided around the outer periphery of a flat roof to prevent rainwater and other water from running down the exterior wall. When installing solar panels on a flat roof equipped with a parapet, it is sometimes required that the height of the top surface of the solar panel be equal to or lower than the height of the parapet. For this reason, there has been a need to lower the height of the mounting part that supports the weight of the solar panel when installing solar panels on a flat roof.

[0004] A known prior art technique that can lower the height of a mounting portion that supports the load of a solar panel on a flat roof is disclosed in Patent Document 1, for example. In this prior art, a mounting member with a mounting portion on which an assembly frame for a solar panel is placed is attached to a main metal fitting that is erected on the upper surface of the flat roof. The mounting member extends to a lower position from a protruding piece that supports the load on the main metal fitting, and supports the mounting portion provided at its tip. This allows the height of the mounting portion that supports the load of the solar panel to be lower than the protruding piece of the main metal fitting. [Prior art documents] [Patent documents]

[0005] [Patent Document 1] Japanese Patent Application Publication No. 2018-025013 Summary of the Invention [Problem to be solved by the invention]

[0006] In the above-mentioned conventional technology, the mounting member is attached to the main metal fitting so as to form a cantilever beam. Therefore, in the above-mentioned conventional technology, if the weight of the installed object (such as a solar panel) is heavy, there is a risk that the mounting member will bend and will not be able to properly support the installed object.

[0007] The present disclosure is directed to reducing deflection caused by the load from an installed object in a mounting member that is attached to a metal fitting (dry foundation) erected on the upper surface of a flat roof. [Means for solving the problem]

[0008] According to one aspect of the present disclosure, there is provided a mounting member that is assembled to an assembly section of a dry foundation erected on the upper surface of a flat roof covered with a waterproofing material, and on which a long cross member that supports the load of a solar cell panel is placed. The mounting member has a fixed section that is placed on the upper surface of the assembly section and fixed to the assembly section. The mounting member also has a mounting section on which the cross member is placed. The mounting member also has an extension section that extends from the fixed section to a position below the fixed section to support the mounting section and position the mounting section spaced above the waterproofing material. A pair of mounting sections are positioned to sandwich the dry foundation from the side. A pair of extension sections extend one toward each of the mounting sections. The space between the pair of mounting sections is filled with rigid gap filler plates. The gap filler plates have through holes that prevent the gap filler plates from interfering with the dry foundation.

[0009] Here, the "horizontal member" may be any of the "vertical beams" arranged in the direction along the water gradient, the "horizontal beams" arranged in the direction intersecting the water gradient, and the "frame material" that forms the assembly frame for the solar panel. Also, the "horizontal member" may be a structure that is generally classified as either a "beam," "beam," "beam," or "beam frame."

[0010] According to the above aspect, by filling the gap between a pair of mounting sections that sandwich the dry foundation laterally with gap filler plates, part of the bending moment of the extension section caused by the load received by one of the mounting sections can be transmitted to the extension section supporting the other mounting section. This allows the bending moment caused by the load from the solar cell panel to be distributed and borne by the two extension sections, reducing deflection in the mounting member.

[0011] According to another aspect, the placing portion is capable of placing the end of a cross member having an insertion groove for another member opened at the end face of the upper portion. The extending portion is provided with a positioning portion and a retracting portion, which will be described later. The positioning portion positions the end of the cross member by abutting a portion below the insertion groove against the end face of the cross member. The retracting portion is positioned in a state where it is retracted toward the dry foundation more than the positioning portion, and the gap between the upper portion of the cross member positioned by the positioning portion and the extending portion is wide enough to allow the insertion of the other member.

[0012] Among the cross members that support the load of solar cell panels, there are some that have insertion grooves on their upper end faces (small end faces) for inserting fasteners for the solar cell panels. According to the above aspect, when a cross member with insertion grooves on its upper end face is placed on a mounting member, it is possible to ensure space for inserting the fasteners into the insertion grooves of the cross member while positioning the end of the cross member with the positioning portion of the extension. As a result, the above aspect can improve the workability of fastening the solar cell panels to the cross member.

[0013] According to another aspect, the mounting member is a long horizontal beam arranged to extend in one direction intersecting the water gradient of the flat roof, and the horizontal beam end is arranged so that it does not protrude in the longitudinal direction of the horizontal beam relative to the edge of the solar panel, and the horizontal beam is placed as a horizontal member. Here, the pair of mounting parts are each capable of placing the horizontal beam end of a different horizontal beam on each of the pair of mounting parts.

[0014] According to the above aspect, when the mounting member is attached to a dry foundation provided in a location sandwiched between the horizontal bar ends of two horizontal bars, the horizontal bar ends of different horizontal bars can be placed on this mounting member. As a result, according to the above aspect, the number of dry foundations required to arrange the same number of solar cell panels side by side can be reduced. [Effects of the Invention]

[0015] According to the present disclosure, deflection due to the load from the solar cell panel can be reduced in a mounting member that is attached to a dry foundation that is erected on the upper surface of a flat roof. [Brief explanation of the drawings]

[0017] A mounting member 10 according to one embodiment of the present disclosure will be described below with reference to the drawings. As shown in FIGS. 1 and 2, this mounting member 10 is assembled to a dry foundation 91 erected on the upper surface 90A of a flat roof 90, and is a mounting member on which long cross members 92 that support the weight of solar cell panels 93 are placed. Here, the upper surface 90A of the flat roof 90 is covered with a waterproofing material 90B. This waterproofing material 90B may be made of a coating film such as glass fiber reinforced plastic or urethane, or may be made of a waterproof sheet made of polyvinyl chloride or synthetic rubber.

[0018] In this embodiment, the flat roof 90 has a water slope (not shown) at a certain angle in one predetermined direction (downward in FIG. 1). In the following, for convenience, the directions "front," "rear," "left," and "right" are defined by referring to the side of the flat roof 90 that is lower "below the water" as the "front" and the side that is upper "above the water" as the "rear."

[0019] As shown in FIG. 1, the flat roof 90 is provided with a drainage groove 90C arranged along its linear front edge, and a parapet 90D rising upward from the front edge of the drainage groove 90C.

[0020] The cross members 92 are long horizontal beams extending in one direction (left-right direction) intersecting the water gradient of the flat roof 90, and are arranged in groups of three, spaced at a predetermined interval in the front-to-back direction. Four rectangular solar cell panels 93 are placed across the three cross members 92, and are arranged in a rectangular pattern in the front-to-back and left-to-right directions on each group of three cross members 92. This allows the three cross members 92 to share and support the load of the four solar cell panels 93. In this embodiment, the length of each cross member 92 is set to a length for "standard construction," which is twice the length of the long side of the solar cell panel 93 across which it is placed. Furthermore, each cross member 92 is arranged so that its left and right end portions 92A (corresponding to "cross member end portions" in this disclosure) do not protrude in the left-to-right direction (the longitudinal direction of the cross member 92) beyond the edges of the solar cell panels 93. Two sets of cross members 92 are arranged side by side in the left-right direction, and each set supports the weight of four solar cell panels 93.

[0021] As shown in FIG. 8 , the mounting member 10 can also be used to mount, as cross members, horizontal beams 95 having a length for "reinforced construction" that is the same as the length of the long sides of the solar cell panels 93 to be spanned. The horizontal beams 95 extend in one direction (left-right direction) that intersects with the water gradient of the flat roof 90, and are arranged in sets of three, lined up at a predetermined interval in the front-to-back direction. Two solar cell panels 93 are placed on the three horizontal beams 95 that form a set, and the set shares and supports the weight of the two solar cell panels 93 by being lined up in a row in the front-to-back direction. In this case, each horizontal beam 95 is arranged so that its left and right horizontal beam end portions 95A do not protrude in the left-to-right direction (the longitudinal direction of the horizontal beam 95) beyond the edges of the solar cell panels 93.

[0022] 1 are erected at positions corresponding to the left and right end portions 92A of two sets of six cross members 92. Specifically, the dry foundations 91 are erected at a total of nine locations: three locations corresponding to the right end portions 92A of the cross members 92 in the right set, three locations corresponding to the left end portions 92A of the cross members 92 in the left set, and three locations sandwiched between the end portions 92A of the cross members 92 in the left and right sets.

[0023] In this embodiment, as shown in FIG. 2, the dry foundation 91 includes a flat base 91C provided along the upper surface 90A of the flat roof 90, and a pedestal 91D erected on the base 91C. The pedestal 91D has a disk-shaped mounting portion 91A at its upper portion, and a screw shaft 91H protruding upward from the center of the mounting portion 91A. A hexagonal nut 91E is screwed onto the screw shaft 91H. With the above configuration, the dry foundation 91 can have an object placed on the upper surface 91B of the mounting portion 91A, and the object can be sandwiched from above and below between the mounting portion 91A and the hexagonal nut 91E.

[0024] The dry foundation 91 may be a conventional dry foundation of a different form from that described above. Specifically, for example, instead of the above-described dry foundation 91, a dry foundation 96 (see FIG. 9) may be employed in which the upper end portion of a cylindrical pedestal 96D erected on a flat base 96C serves as an assembly portion 96A, and a screw shaft 96H protrudes upward from the center of this assembly portion 96A.

[0025] As shown in Fig. 1, the mounting members 10 of this embodiment are attached one by one to each of the dry foundations 91 erected at nine locations. These nine mounting members 10 have exactly the same configuration. Therefore, in the following, detailed explanations of the nine mounting members 10 arranged in a grid pattern in Fig. 1 will be given by referring to the central mounting member 10 as a representative. Detailed explanations of the remaining eight mounting members 10 will be omitted.

[0026] As shown in Fig. 2, the mounting member 10 is placed on an upper surface 91B of an assembly portion 91A of a dry foundation 91 and includes a fixed portion 11 that is fixed to the assembly portion 91A by being sandwiched between a hexagonal nut 91E and the assembly portion 91A. As shown in Figs. 4 to 6, the fixed portion 11 of this embodiment is configured such that an elongated hole 11A having a width that allows a screw shaft 91H to be inserted through it is opened in the center of a flat plate, and a washer 11B having approximately the same diameter as the assembly portion 91A is attached. As shown in Fig. 2, the fixed portion 11 is placed on the upper surface 91B of the assembly portion 91A with the screw shaft 91H inserted through the elongated hole 11A. Furthermore, washer 11B is interposed between fixed portion 11 and hexagonal nut 91E with screw shaft 91H inserted therethrough, and is pressed against assembly portion 91A by this hexagonal nut 91E, thereby suppressing wobble of fixed portion 11 fixed to assembly portion 91A. Note that additional washers and / or spring washers (neither of which are shown) may be interposed between washer 11B and hexagonal nut 91E as appropriate.

[0027] The mounting member 10 has a pair of mounting portions 12 positioned on either side of the dry foundation 91 in the left-right (lateral) direction. Each mounting portion 12 is capable of supporting the load of an end portion 92A of a cross member 92 when placed thereon. In this embodiment, the pair of mounting portions 12 are supported by a pair of extending portions 13 that extend from the fixed portions 11 toward each mounting portion 12. These extending portions 13 extend to positions below the fixed portions 11 and above the waterproofing material 90B, positioning each mounting portion 12 at a distance above the waterproofing material 90B.

[0028] In the mounting member 10, the space between the pair of left and right mounting portions 12 is filled with a rigid gap filler plate 14, as shown in Figures 4 and 6. This gap filler plate 14 has a through hole 14A that prevents the gap filler plate 14 from interfering with the dry foundation 91. In this embodiment, the gap filler plate 14 is integrally formed with the fixed portion 11, the mounting portion 12, and the extending portion 13 (see Figure 4). The through hole 14A is formed as a circular (see Figure 6) through-hole that passes through the gap filler plate 14 in the up-down direction (see Figure 4).

[0029] Here, the mounting portion 12 and the extending portion 13 on the left side of the mounting member 10 and the mounting portion 12 and the extending portion 13 on the right side have exactly the same configuration. Therefore, a rear view (not shown) of the mounting member 10 appears the same as a front view (see FIG. 4) of the mounting member 10. Also, a left side view (not shown) of the mounting member 10 appears the same as a right side view (see FIG. 7) of the mounting member 10.

[0030] In the following, detailed explanations of each pair of mounting portions 12 and extending portions 13 that sandwich the dry foundation 91 from the left and right in Fig. 2 will be given by describing the left mounting portion 12 and extending portion 13. Detailed explanations of the right mounting portion 12 and extending portion 13 will be omitted.

[0031] In this embodiment, the cross member 92 is an extruded square aluminum pipe having an insertion groove 92D for an additional member opened in an end face 92C (small end face) of an upper portion 92B thereof, as shown in Fig. 2. Fasteners 93A (see Figs. 2 and 3; not shown in Fig. 1) that fasten the edges of two solar cell panels 93 adjacent in the front-to-rear direction (see Fig. 3) can be inserted as "another member" into the insertion groove 92D from the side of the end face 92C.

[0032] The cross member 92 has a lower portion 92E below the insertion groove 92D, and is provided with engaging flanges 92G extending from a bottom surface 92F on both sides in the width direction (front-rear direction). The leading edge portions of these engaging flanges 92G are raised upward.

[0033] As shown in Fig. 3, the mounting portion 12 is formed so that its widthwise dimension (front-rear direction) is larger than the maximum width of the cross member 92 (the width of the bottom surface 92F including the engaging flange 92G). In addition, an attachment groove 12B is provided on the upper surface of the mounting portion 12 for attaching two bolts 12A that secure the end portion 92A of the cross member 92 to the mounting portion 12. As shown in Figs. 4 to 7, this attachment groove 12B extends linearly in the front-rear direction from the front end to the rear end of the mounting portion 12, and furthermore, a barb 12E (see Fig. 4) is attached to the upper opening to prevent it from coming off.

[0034] As shown in Fig. 4, each bolt 12A is attached with its head 12C facing downward and this head 12C sliding into the attachment groove 12B from the front or rear, with the shank 12D protruding upward from the opening of the attachment groove 12B. Fixing brackets 12G are attached to each of these shanks 12D with flange nuts 12F. As shown in Fig. 3, these fixing brackets 12G engage with engaging flanges 92G protruding on both sides of the cross member 92 in the width direction (front-rear direction), thereby fixing the cross member 92 to the support part 12.

[0035] 2, the extending portion 13 of this embodiment is configured to have a positioning portion 13A, a retracting portion 13B, and a rising portion 13C, each of which will be described later. The rising portion 13C is a plate-shaped portion that rises upward from the end of the mounting portion 12 on the dry foundation 91 side. In a mounted state in which the end portion 92A of the cross member 92 is placed on the mounting portion 12, the rising portion 13C faces an end face 92C of the lower portion 92E of the end portion 92A that is below the insertion groove 92D.

[0036] The positioning portion 13A is a protrusion that protrudes from the plate surface of the rising portion 13C on the side of the placing portion 12. In the above-described placed state, the positioning portion 13A is able to position the end portion 92A of the cross member 92 by abutting against the end surface 92C of the lower portion 92E of the cross member 92. In this embodiment, the positioning portion 13A is formed as a protrusion (see FIG. 3) that extends linearly in the front-rear direction and is provided on the plate surface of the rising portion 13C on the side of the placing portion 12.

[0037] 2, the retraction portion 13B has an angled configuration that connects the end of the fixed portion 11 on the side of the placing portion 12 and the upper end of the rising portion 13C. The retraction portion 13B is positioned in a state where it is retracted closer to the dry foundation 91 than the positioning portion 13A. As a result, in the above-mentioned placed state, the retraction portion 13B makes the gap between the upper portion 92B of the cross member 92 positioned by the positioning portion 13A and the extending portion 13 wide enough to allow the fastener 93A to be inserted.

[0038] According to the above-described mounting member 10, by filling the gap between the pair of mounting portions 12 that sandwich the dry foundation 91 laterally (left and right), with gap filling plates 14, it is possible to transmit part of the bending moment of the extension portion 13 caused by the load received by one of the mounting portions 12 to the extension portion 13 that supports the other mounting portion 12. As a result, the mounting member 10 distributes and bears the bending moment caused by the load from the solar cell panel 93 between the two extension portions 13, and deflection of the mounting member 10 can be reduced.

[0039] Furthermore, with the mounting member 10, when a cross member 92 having an insertion groove 92D formed on an end face 92C (small end face) of an upper portion 92B is placed on the mounting member 10, it is possible to ensure space for inserting the fastener 93A into the insertion groove 92D of the cross member 92 while positioning the end portion 92A of the cross member 92 with the positioning portion 13A of the extension portion 13. As a result, with the mounting member 10, it is possible to improve the workability of fastening the solar cell panel 93 to the cross member 92.

[0040] Furthermore, with the mounting member 10, different cross members 92 can be placed on each of the pair of mounting portions 12. At this time, when the bending moment of the extension portion 13 supporting one of the mounting portions 12 is transmitted to the extension portion 13 supporting the other of the mounting portions 12, it acts to cancel out the bending moment of the other of the extending portions 13. Also, when the bending moment of the extension portion 13 supporting one of the mounting portions 12 is transmitted to the extension portion 13 supporting the other of the mounting portions 12, it acts to cancel out the bending moment of the other of the extending portions 13. This allows the mounting member 10 to reduce deflection when different cross members 92 are placed on each of the pair of mounting portions 12.

[0041] Furthermore, according to the mounting member 10, when the mounting member 10 is assembled to a dry foundation 91 provided in a location sandwiched between the ends 92A of two cross members 92, the ends 92A of different cross members 92 can be placed on this mounting member 10. As a result, the mounting member 10 can reduce the number of dry foundations 91 required to arrange the same number of solar cell panels 93 side by side.

[0042] The above will be explained in more detail. Fig. 10 shows an example of a support configuration for solar cell panels 93 according to the prior art, in which vertical beams 94 are placed as cross members on the above-mentioned dry foundation 91. In this example, two solar cell panels 93 lined up in the front-to-rear direction are placed on two vertical beams 94 that also extend in the front-to-rear direction. Both ends of these vertical beams 94 protrude forward or rearward relative to the solar cell panels 93, and each protruding portion is supported from below by one dry foundation 91. For this reason, in the above example of the prior art, when arranging a predetermined number of solar cell panels 93 (e.g., eight) side by side, it is necessary to secure extra space by the amount of the protruding portions at both ends of the vertical beams 94.

[0043] The number of dry foundations 91 required to arrange solar panels 93 in a rectangle in the above example and an example of the present disclosure that uses the above-mentioned horizontal beams 92 for "standard construction" (see FIG. 1) is compared in Table 1 below. In the following explanation, the "number of rows" refers to the number of solar panels 93 arranged in the front-to-back direction, and the "number of columns" refers to the number of solar panels 93 arranged in the left-to-right direction. Furthermore, it is assumed that a maximum of two columns (in the case of the horizontal beams 92 of the present disclosure (horizontal beams for "standard construction")) or two columns (in the case of the horizontal beams (vertical beams 94) of the conventional technology) of solar panels 93 can be placed on one horizontal beam.

[0044] [Table 1]

[0045] According to Table 1, except when the "number of rows" is "1" (i.e., the solar cell panels 93 are lined up in a single row in the front-to-back direction), it can be said that the present disclosure requires fewer dry foundations 91. Furthermore, the difference in the required number of dry foundations 91 becomes more pronounced as the "number of rows" increases (i.e., the number of solar cell panels 93 lined up in the left-to-right direction increases).

[0046] Furthermore, the number of dry foundations 91 required to arrange solar panels 93 in a rectangular pattern in the above-mentioned example of the conventional technology (see FIG. 10) and the example of the present disclosure (see FIG. 8) that uses the above-mentioned horizontal crosspieces 95 for "reinforced construction" is compared in the following Table 2. Here, it is assumed that no more than two rows of solar panels 93 are placed on each horizontal crosspiece 95 for "reinforced construction."

[0047] [Table 2]

[0048] According to Table 2, except when the "number of rows" is relatively small (for example, five rows or less in the case of four rows), it can be said that the present disclosure requires fewer dry foundations 91. Furthermore, the difference in the required number of dry foundations 91 becomes more pronounced as the "number of rows" increases (i.e., the number of solar cell panels 93 lined up in the left-right direction increases).

[0049] The above-described embodiment has been used to describe the mode for carrying out the present disclosure. However, it will be apparent to those skilled in the art that various substitutions, modifications, and alterations are possible without departing from the scope of the present disclosure. In other words, the mode for carrying out the present disclosure may include all substitutions, modifications, and alterations that do not depart from the spirit and purpose of the claims appended hereto. For example, the following various modes can be implemented as modes for carrying out the present disclosure.

[0050] (1) The present disclosure is not limited to applications to mounting members assembled to the above-described dry foundation 91 (see FIG. 2) or dry foundation 96 (see FIG. 9), but can be applied to mounting members corresponding to dry foundations of various configurations. Examples of dry foundation configurations include a configuration in which fastening bolts are inserted into angle fittings erected on the top surface of a flat roof, or a configuration consisting only of ribs erected on the top surface of a flat roof. In this case, the specific configuration of the fixed part of the mounting member can be changed as appropriate depending on the configuration of the dry foundation to which it is to be assembled.

[0051] (2) The mounting member of the present disclosure is not limited to a pair of mounting sections that sandwich the dry foundation from the left and right, on which the ends of the horizontal beams serving as cross members are placed. In other words, the mounting member of the present disclosure may be a pair of mounting sections positioned to sandwich the dry foundation from the front and back, with the middle portions of the horizontal beams or the ends of the vertical beams placed on one or both of these mounting sections.
