Next, after a nut is fastened to the shaft portion of the bolt 19a, the first fixing member 12 and the second fixing member 14 are sandwiched between the bolt 19a and the nut. Thereby, the first upper portion 16 of the first stationary member 12 and the second lower portion 29 of the second stationary member 14 are secured together.
The operation and effect of the present embodiment will be described below.
(1) The fixing structure of the solar panel stand according to the present embodiment includes: a frame structure body that supports the solar panel; an installation surface side structure 1A, the installation surface side structure 1A being disposed on an installation surface; and a fixing member 10A for connecting and fixing the frame structure and the installation surface side structure 1A in a relatively tiltable manner by the fixing member 10A. The fixing member 10A includes: a first fixing member 12, the first fixing member 12 being tiltable around a first axis 11; and a second fixing member 14, the second fixing member 14 being tiltable around a second axis 13 intersecting the first axis 11.
When the frame structure is fixed to the installation surface side structure 1A, the frame structure needs to be fixed so as not to be twisted. Otherwise, the support surface of the solar panel of the frame structure may be twisted, which may hinder the support of the solar panel. Since the fixing members 10A (the first fixing member 12 and the second fixing member 14) for connecting and fixing the frame structure of the mount for a solar panel to the installation surface-side structure 1A have the function of being inclined in two different directions, the frame structure can be relatively easily fixed without twisting.
As described above, according to the fixing structure of the mount for a solar panel of the present embodiment, it is possible to cope with inclination in two directions with a relatively simple structure.
(2) The first fixing member 12 has a first lower portion 15 and a first upper portion 16, the first lower portion 15 is fixed to the installation surface-side structure 1A, and the first upper portion 16 is fixed to the second fixing member 14.
Thereby, the first fixing member 12 can be fixed to the installation surface side structure 1A so that the first fixing member 12 is inclined at a desired inclination angle.
(3) The first upper portion 16 of the first fixing member 12 has a first receiving portion 25, the first receiving portion 25 receiving at least a part of the second fixing member 14, and the first receiving portion 25 has a first intermediate portion 17 and a pair of upper side portions 26, 26 extending upward from both side portions of the first intermediate portion 17, and is formed in a U shape. An uneven structure 28 is formed on the outer surface of the upper side surface portion 26, and a plurality of concave portions and convex portions are formed in the uneven structure 28 at intervals in the height direction of the first fixing member 12.
By forming the first receiving portion 25 in the first upper portion 16 of the first fixing member 12, the first fixing member 12 and the second fixing member 14 can be stably fixed, and the second fixing member 14 can be easily inclined with respect to the first fixing member 12. Further, by forming the concave-convex structure 28 on the outer side surface of the upper side surface portion 26 of the first fixing member 12, the bolt and nut fixation is performed using the spacer 47 formed with the similar concave-convex structure 48 (see fig. 3), whereby the fixing strength of the first fixing member 12 and the second fixing member 14 can be improved.
(4) The first lower portion 15 of the first fixing member 12 has: a first boss portion 20, the first boss portion 20 defining a first axis 11; and a pair of first inclined surface portions 21, the pair of first inclined surface portions 21, 21 extending from both side portions of the first intermediate portion 17 toward the first boss portion 20. The center axis (first axis 11) of the first boss portion 20 is arranged parallel to a line bisecting the first intermediate portion 17 in the width direction, and the first lower portion 15 has a shape symmetrical with respect to the width direction.
By connecting the first intermediate portion 17 of the first fixing member 12 to the first boss portion 20 by the pair of first inclined surface portions 21, it is possible to provide a structure that is less likely to interfere with the installation surface-side structure 1A when the first fixing member 12 is inclined. Thus, the tilt range of the first fixing member 12 can be enlarged. Further, by providing the first fixing member 12 in a shape symmetrical with respect to the width direction, the center of gravity balance of the first fixing member 12 can be kept well.
(5) The second fixing member 14 has a second lower portion 29 and a second upper portion 30, the second lower portion 29 is fixed to the first fixing member 12, and the second upper portion 30 is fixed to the frame structure via a bracket member 32.
Thereby, the second fixing member 14 can be fixed to the first fixing member 12 so that the second fixing member 14 is inclined at a desired inclination angle. Further, by sandwiching the bracket member 32 between the second fixing member 14 and the frame structure, the position of the frame structure can be finely adjusted.
(6) The second upper portion 30 of the second fixing member 14 has: the second intermediate portion 31; and a pair of engaging portions 37, the pair of engaging portions 37, 37 being formed continuously with both side portions of the second intermediate portion 31, the engaging portions 37 engaging with the holder member 32.
This allows the bracket member 32 to be temporarily fixed using the engaging portion 37, and allows other elongated members to be easily fixed to the second fixing member 14, for example.
(7) The second lower portion 29 of the second fixing member 14 has: a second sleeve portion 33, the second sleeve portion 33 defining a second axis 13; and a pair of second inclined surface portions 34, the pair of second inclined surface portions 34, 34 extending from both side portions of the second intermediate portion 31 toward the second boss portion 33. The center axis (second axis 13) of the second boss portion 33 is arranged parallel to a line bisecting the second intermediate portion 31 in the width direction, and the second lower portion 29 has a shape symmetrical with respect to the width direction.
By connecting the first fixing member 14 from the first intermediate portion 31 to the second boss portion 33 by the pair of second inclined surface portions 34, it is possible to provide a structure that is less likely to interfere with the first fixing member 12 when the second fixing member 14 is inclined. Thus, the tilt range of the second fixing member 14 can be enlarged. Further, by providing the second fixing member 14 with a shape symmetrical with respect to the width direction, the center of gravity balance of the second fixing member 14 can be kept well.
(8) The bracket member has: a housing part 41, the housing part 41 being disposed in a pair at the center in the width direction and being capable of housing the head of a bolt or a nut; a hollow portion 42, the hollow portion 42 being disposed outside the width direction so as to sandwich the housing portion 41; and a bracket-side engaging portion 43, the bracket-side engaging portion 43 being formed on an outer side surface of the hollow portion 42.
By forming the housing portion 41 above and below the central portion of the bracket member 32, it is possible to easily position the bolt or the nut, and to ensure a large contact area with the target member (the frame structure, the second fixing member 14) on the upper and lower surfaces. Further, by forming the hollow portion 42 in the holder member 32, the strength of the holder member 32 can be improved. By forming the holder-side engaging portion 43 in the holder member 32, the holder member 32 can be temporarily fixed using the holder-side engaging portion 43, and the holder member 32 can be easily fixed to the second fixing member 14.
(9) The first fixing member 12, the second fixing member 14, and the bracket member 32 are formed of an extruded profile made of an aluminum alloy.
Accordingly, the entire fixing member 10A and the bracket member 32 can be made lighter in weight as compared with the case where each member is formed of a steel material. In addition, the dimensional accuracy of each member can be improved, the solar panel stand can be easily and accurately installed, and excellent corrosion resistance and appearance can be obtained. Further, since the aluminum alloy is excellent in recyclability, the materials of the first fixing member 12, the second fixing member 14, and the bracket member 32 can be reused after the solar panel mount is removed.
(10) The fixing member 10A includes: a first fixing member 12, the first fixing member 12 being tiltable around a first axis 11; and a second fixing member 14, the second fixing member 14 being tiltable around a second axis 13 intersecting the first axis 11. The first stationary member 12 has a first lower portion 15 and a first upper portion 16. The first upper portion 16 of the first fixing member 12 has a first receiving portion 25, the first receiving portion 25 receiving at least a part of the second fixing member 14, and the first receiving portion 25 has a first intermediate portion 17 and a pair of upper side portions 26, 26 extending upward from both side portions of the first intermediate portion 17, and is formed in a U shape. The first lower portion 15 of the first fixing member 12 has: a first boss portion 20, the first boss portion 20 defining a first axis 11; and a pair of first inclined surface portions 21, the pair of first inclined surface portions 21, 21 extending from both side portions of the first intermediate portion 17 toward the first boss portion 20, a central axis (first axis 11) of the first boss portion 20 being disposed parallel to a line bisecting the first intermediate portion 17 in the width direction, and the first lower portion 15 having a shape symmetrical with respect to the width direction.
The fixing member 10A (the first fixing member 12 and the second fixing member 14) for connecting and fixing two structures has a function of inclining with respect to two different directions, and therefore, the two structures can be inclined at a desired inclination angle and fixed.
In summary, according to the fixing member 10A, it is possible to cope with inclination with respect to two directions by a relatively simple structure.
Further, by connecting the first intermediate portion 17 of the first fixing member 12 to the first boss portion 20 by the pair of first inclined surface portions 21, it is possible to provide a structure that is less likely to interfere with a structure to be fixed when the first fixing member 12 is inclined. Thus, the tilt range of the first fixing member 12 can be enlarged. Further, by providing the first fixing member 12 in a shape symmetrical with respect to the width direction, the center of gravity balance of the first fixing member 12 can be kept well.
(11) At least one first hollow portion 23 is formed in a region surrounded by the first intermediate portion 17, the first boss portion 20, and the pair of first inclined surface portions 21, 21 of the first fixing member 12.
By forming the first hollow portion 23 in the first fixing member 12, the strength of the first fixing member 12 can be improved.
(12) The upper side surface portion 26 of the first fixing member 12 is formed to vertically stand from the first intermediate portion 17.
This allows the other member (second fixing member 14) fixed to the first upper portion 16 of the first fixing member 12 to be sandwiched between the pair of upper side surface portions 26, and the first fixing member 12 and the other member (second fixing member 14) to be stably fixed.
(13) An uneven structure 28 is formed on the outer surface of the upper side surface portion 26 of the first fixing member 12, and a plurality of concave portions and convex portions are formed in the uneven structure 28 at intervals in the height direction of the first fixing member 12.
By forming the concave-convex structure 28 on the outer side surface of the upper side surface portion 26 of the first fixing member 12, the bolt and nut fixation is performed using the spacer 47 formed with the similar concave-convex structure 48 (see fig. 3), whereby the fixing strength between the first fixing member 12 and another member (the second fixing member 14) can be improved.
(14) The second stationary member 14 has a second lower portion 29 and a second upper portion 30. The second upper portion 30 of the second fixing member 14 has: the second intermediate portion 31; and a pair of engaging portions 37, the pair of engaging portions 37, 37 being formed continuously with both side portions of the second intermediate portion 31 and engaging with another member. The second lower portion 29 of the second fixing member 14 has: a second sleeve portion 33, the second sleeve portion 33 defining a second axis 13; and a pair of second inclined surface portions 34, the pair of second inclined surface portions 34, 34 extending from both side portions of the second intermediate portion 31 toward the second boss portion 33, a central axis (second axis 13) of the second boss portion 30 being arranged parallel to a line bisecting the second intermediate portion 31 in the width direction, and the second lower portion 29 having a shape symmetrical with respect to the width direction.
By connecting the second intermediate portion 31 to the second boss portion 33 of the second fixing member 14 by the pair of second inclined surface portions 34, it is possible to provide a structure that is less likely to interfere with another member (the first fixing member 12) when the second fixing member 14 is inclined. Thus, the tilt range of the second fixing member 14 can be enlarged. Further, by providing the second fixing member 14 with a shape symmetrical with respect to the width direction, the center of gravity balance of the second fixing member 14 can be kept well.
Further, the other member (the holder member 32) can be temporarily fixed by using the engaging portion 37, and for example, the other elongated member can be easily fixed to the second fixing member 14.
(15) At least one second hollow portion 36 is formed in a region surrounded by the second intermediate portion 31, the second boss portion 33, and the pair of second inclined surface portions 34, 34 of the second fixing member 14.
By forming the second hollow portion 36 in the first fixing member 14, the strength of the second fixing member 14 can be improved.
(16) The two structures are a frame structure of a mount for a solar panel and an installation surface side structure 1A.
Accordingly, the frame structure of the mount for a solar panel and the installation surface-side structure 1A can be fixed so as to be inclined with respect to each other, and the inclination with respect to two directions can be coped with by a relatively simple structure as the mount for a solar panel.
(17) The first fixing member 12 and the second fixing member 14 are formed of an extruded profile made of an aluminum alloy.
Accordingly, the weight of the entire fixing member 10A can be reduced as compared with the case where each member is formed of a steel material. In addition, the dimensional accuracy of each member can be improved, the solar panel mount can be easily and accurately installed, and excellent corrosion resistance and appearance can be obtained. Further, since the aluminum alloy is excellent in recycling property, the materials of the first fixing member 12 and the second fixing member 14 can be reused after the solar panel mount is removed.

Further, an uneven structure 68 is formed on the outer side surface of the upper side surface portion 66, and a plurality of concave portions and convex portions are formed on the uneven structure 68 at intervals in the height direction of the first fixing member 52.
The second fixing member 54 has: a second lower portion 69, the second lower portion 69 constituting a lower portion of the second fixing member 54; and a second upper portion 70, the second upper portion 70 constituting an upper portion of the second fixing member 54. The second lower portion 69 is fixed to the first upper portion 56 of the first fixing member 52 via the second fastening member 59, and the second upper portion 70 is fixed to the frame structure via the beam 71.
The second lower portion 69 of the second fixing member 54 has: a cylindrical second sleeve portion 72, the second sleeve portion 72 defining a second axis 53; and a pair of second inclined surface portions 73, the pair of second inclined surface portions 73, 73 extending from the second upper portion 70 toward the second boss portion 72. The second bushing portion 72 has a second lower bolt hole 74, and the bolt 59a of the second fastening member 59 is inserted through the second lower bolt hole 74.

At least one second hollow portion 75 is formed in a region surrounded by the second upper portion 70, the second boss portion 72, and the pair of second inclined surface portions 73, 73. In the present embodiment, one second hollow portion 75 is formed in the above-described region.
The second upper portion 70 of the second fixing member 54 has a plate-like portion 76, the plate-like portion 76 extends in the width direction of the second fixing member 54, and the plate-like portion 76 is fixed to the beam 71. An uneven structure 77 is formed on the lower surface of the plate-shaped portion 76, a plurality of concave portions and convex portions are formed on the uneven structure 77 at intervals in the width direction of the second fixing member 54, and the beam 71 is placed on and fixed to the upper surface of the plate-shaped portion 76. Therefore, the plate-shaped portion 76 has a second upper bolt hole 79 formed therethrough, the bolt 78 for fixing the beam 71 to the second fixing member 54 is inserted through the second upper bolt hole 79, and the second upper bolt hole 79 is formed in an elongated hole shape extending in the width direction W of the mount for a solar panel.
The beam 71 is formed of a profile having a hat-shaped cross section and extends in the width direction of the second fixing member 54 (i.e., the extending direction of the first axis 51). The beam 71 is placed on and fixed to the second upper portion 70 (plate portion 76) of the second fixing member 54. Specifically, the beam 71 includes: a bottom plate portion 80; a pair of side plates 81, the pair of side plates 81, 81 extending upward from both side portions of the bottom plate 80; and a protruding plate portion 82, the protruding plate portion 82 protruding outward in the width direction of the beam 71 from the upper end of the side plate portion 81.

The beam-side lower bolt holes 83 (see fig. 6) are formed in a long hole shape extending in the depth direction D of the solar panel mount, and the beam-side upper bolt holes 84 are formed in a circular hole shape. Since the bolt hole of the beam 71 (beam-side lower bolt hole 83) and the bolt hole of the second fixing member 54 (second upper bolt hole 79) are long holes extending in directions orthogonal to each other, positioning with respect to the front-rear direction and the width direction is easy when the beam 71 and the second fixing member 54 are fixed.
In the present embodiment, a plurality of assemblies (modules) 85 each including the first fixing member 52 and the second fixing member 54 are arranged. Further, one end of the beam 71 is fixed to the second fixing member 54 of one assembly 85, and the other end is fixed to the second fixing member 54 of the other assembly 85. That is, the beam 71 is bridged and fixed between the plurality of second fixing members 54 (plate-shaped portions 76), thereby forming a rigid frame structure (column-beam structure).
The first fixing member 52, the second fixing member 54, and the beam 71 are formed of a press-formed material made of an aluminum alloy, similarly to the pillar member 6 having a hat-shaped cross section.
The first lower portion 55 of the first fixing member 52 is fastened to the pillar member 6 of the installation surface-side structure 1B by the first fastening member 58 including the bolt 58a and the nut (not shown).

Next, when a nut is fastened to the shaft portion of the bolt 58a, the first fixing member 52 and the pillar member 6 are sandwiched between the bolt 58a and the nut. Thereby, the first lower portion 55 of the first fixing member 52 and the pillar member 6 of the installation surface-side structure 1B are fastened together.
The first upper portion 56 of the first fixing member 52 and the second lower portion 69 of the second fixing member 54 are fastened by a washer (washer) 86 and a second fastening member 59 composed of a bolt 59a and a nut 59 b.

Thereby, the first upper portion 56 of the first fixing member 52 and the second lower portion 69 of the second fixing member 54 are fastened together.
The operation and effect of the present embodiment will be described below.
(1) The fixing structure of the solar panel stand according to the present embodiment includes: a frame structure body that supports the solar panel; an installation surface side structure 1B, the installation surface side structure 1B being disposed on an installation surface; and a fixing member 10B for connecting and fixing the frame structure and the installation surface side structure 1B in an inclinable manner by the fixing member 10B. The fixing member 10B includes: a first fixing member 52, the first fixing member 52 being tiltable around a first axis 51; and a second fixing member 54, the second fixing member 54 being tiltable around a second axis 53 intersecting the first axis 51.
When the frame structure is fixed to the installation surface side structure 1B, the frame structure needs to be fixed so as not to be twisted. Otherwise, the support surface of the solar panel of the frame structure may be distorted, and there is a possibility that the support of the solar panel may be hindered. Since the fixing members 10B (the first fixing member 52 and the second fixing member 54) for connecting and fixing the frame structure of the mount for a solar panel to the installation surface-side structure 1B have the function of being inclined in two different directions, the frame structure can be relatively easily fixed without twisting.
As described above, according to the fixing structure of the mount for a solar panel of the present embodiment, it is possible to cope with inclination in two directions with a relatively simple structure.
(2) The first fixing member 52 has a first lower portion 55 and a first upper portion 56, the first lower portion 55 is fixed to the installation surface-side structure 1B, and the first upper portion 56 is fixed to the second fixing member 54.
Thereby, the first fixing member 52 can be fixed to the installation surface-side structure 1B so that the first fixing member 52 is inclined at a desired inclination angle.
(3) The first upper portion 56 of the first fixing member 52 has a first receiving portion 65, the first receiving portion 65 receiving at least a part of the second fixing member 54, and the first receiving portion 65 has a first intermediate portion 57 and a pair of upper side portions 66, 66 extending upward from both side portions of the first intermediate portion 57, and is formed in a U shape. An uneven structure 68 is formed on the outer surface of the upper side surface portion 66, and a plurality of concave portions and convex portions are formed on the uneven structure 68 at intervals in the height direction of the first fixing member 52.
By forming the first receiving portion 65 in the first upper portion 56 of the first fixing member 52, the first fixing member 52 and the second fixing member 54 can be stably fixed, and the second fixing member 54 can be easily inclined with respect to the first fixing member 52. Further, by forming the concave-convex structure 68 on the outer side surface of the upper side surface portion 66 of the first fixing member 52, the bolt and nut fixation is performed using the spacer 86 in which the similar concave-convex structure 87 (see fig. 6) is formed, whereby the fixing strength of the first fixing member 52 and the second fixing member 54 can be improved.
(4) The first lower portion 55 of the first fixing member 52 has: a first boss portion 60, the first boss portion 60 defining a first axis 51; and a pair of first inclined surface portions 61, the pair of first inclined surface portions 61, 61 extending from both side portions of the first intermediate portion 57 toward the first boss portion 60. The center axis (first axis 51) of the first boss portion 60 is arranged parallel to a line bisecting the first intermediate portion 57 in the width direction, and the first lower portion 55 has a shape symmetrical with respect to the width direction.
By connecting the first fixing member 52 from the first intermediate portion 57 to the first boss portion 60 by the pair of first inclined surface portions 61, it is possible to provide a structure that is less likely to interfere with the installation surface-side structural body 1B when the first fixing member 52 is inclined. Thus, the tilt range of the first fixing member 52 can be enlarged. Further, by providing the first fixing member 52 with a shape symmetrical with respect to the width direction, the center of gravity balance of the first fixing member 52 can be kept well.
(5) The second fixing member 54 has a second lower portion 69 and a second upper portion 70, the second lower portion 69 is fixed to the first fixing member 52, and the second upper portion 70 is fixed to the frame structure via a beam 71.
Thereby, the second fixing member 54 can be fixed to the first fixing member 52 so that the second fixing member 54 is inclined at a desired inclination angle. Further, by sandwiching the beam 71 between the second fixing member 54 and the frame structure, the position of the frame structure can be finely adjusted.
(6) The second upper portion 70 of the second fixing member 54 has a plate-like portion 76, and the plate-like portion 76 extends in the width direction of the second fixing member 54. An uneven structure 77 is formed on the lower surface of the plate-like portion 76, a plurality of recesses and boss portions are formed in the uneven structure 77 at intervals in the width direction of the second fixing member 54, and the beam 71 is placed on and fixed to the upper surface of the plate-like portion 76.
By forming the concave-convex structure 77 on the lower surface of the second upper portion 70 (plate-shaped portion 76) of the second fixing member 54, bolt-and-nut fixing is performed using a spacer (not shown) formed with the same concave-convex structure, whereby the fixing strength between the second fixing member 54 and the beam 71 can be improved.
(7) The second lower portion 69 of the second fixing member 54 has: a second bushing portion 72, the second bushing portion 72 defining a second axis 53; and a pair of second inclined surface portions 73, the pair of second inclined surface portions 73 extending from the lower surface of the plate-like portion 76 toward the second boss portion 72. The center axis (second axis 53) of the second boss portion 72 is arranged parallel to a line bisecting the second upper portion 70 in the width direction, and the second lower portion 69 has a shape symmetrical with respect to the width direction.
By connecting the second upper portion 70 (plate-like portion 76) of the second fixing member 54 to the second boss portion 72 by the pair of second inclined surface portions 73, a structure is formed in which interference with the first fixing member 52 is less likely when the second fixing member 54 is inclined. Thus, the tilt range of the second fixing member 54 can be enlarged. Further, by providing the second fixing member 54 with a shape symmetrical with respect to the width direction, the center of gravity balance of the second fixing member 54 can be kept well.
(8) A plurality of assemblies 85 each including the first fixing member 52 and the second fixing member 54 are arranged. One end of the beam 71 is fixed to the second fixing member 54 of one assembly 85, and the other end is fixed to the second fixing member 54 of the other assembly 85.
By erecting and fixing the beam 71 between the plurality of second fixing members 54 (plate-shaped portions 76), a rigid frame structure (column-beam structure) can be formed, and a high-strength fixing structure can be obtained.
(9) The first fixing member 52, the second fixing member 54, and the beam 71 are formed of an extruded profile made of an aluminum alloy.
As a result, the entire fixing member 10B and the beam 71 can be made lighter than when the members are made of steel. In addition, the dimensional accuracy of each member can be improved, the solar panel stand can be easily and accurately installed, and excellent corrosion resistance and appearance can be obtained. Further, since the aluminum alloy is excellent in recyclability, the materials of the first fixing member 52, the second fixing member 54, and the beam 71 can be reused after the solar panel mount is removed.
(10) The fixing member 10B includes: a first fixing member 52, the first fixing member 52 being tiltable around a first axis 51; and a second fixing member 54, the second fixing member 54 being tiltable around a second axis 53 intersecting the first axis 51. The first stationary member 52 has a first lower portion 55 and a first upper portion 56. The first upper portion 56 of the first fixing member 52 has a first receiving portion 65, the first receiving portion 65 receiving at least a part of the second fixing member 54, and the first receiving portion 65 has a first intermediate portion 57 and a pair of upper side portions 66, 66 extending upward from both side portions of the first intermediate portion 57, and is formed in a U shape. The first lower portion 55 of the first fixing member 52 has: a first boss portion 60, the first boss portion 60 defining a first axis 51; and a pair of first inclined surface portions 61, the pair of first inclined surface portions 61, 61 extending from both side portions of the first intermediate portion 57 toward the first boss portion 60, a central axis (first axis 51) of the first boss portion 60 being disposed parallel to a line bisecting the first intermediate portion 57 in the width direction, and the first lower portion 55 having a shape symmetrical with respect to the width direction.
The fixing member 10B (the first fixing member 52 and the second fixing member 54) for connecting and fixing two structures has a function of inclining with respect to two different directions, and therefore, the two structures can be inclined at a desired inclination angle and fixed.
In summary, according to the fixing member 10B, it is possible to cope with inclination with respect to two directions by a relatively simple structure.
Further, the first fixing member 52 is connected from the first intermediate portion 57 to the first boss portion 60 by the pair of first inclined surface portions 61, so that the first fixing member 52 is provided with a structure that is less likely to interfere with a structure to be fixed when tilted. Thus, the tilt range of the first fixing member 52 can be enlarged. Further, by providing the first fixing member 52 with a shape symmetrical with respect to the width direction, the center of gravity balance of the first fixing member 52 can be kept well.
(11) At least one first hollow portion 63 is formed in a region surrounded by the first intermediate portion 57, the first boss portion 60, and the pair of first inclined surface portions 61, 61 of the first fixing member 52.
By forming the first hollow portion 63 in the first fixing member 52, the strength of the first fixing member 52 can be increased.
(12) The upper side surface portion 66 of the first fixing member 52 is formed to vertically stand from the first intermediate portion 57.
Thus, the other member (second fixing member 54) fixed to the first upper portion 56 of the first fixing member 52 can be sandwiched by the pair of upper side surface portions 66, and the first fixing member 52 and the other member (second fixing member 54) can be stably fixed.
(13) An uneven structure 68 is formed on the outer surface of the upper side surface portion 66 of the first fixing member 52, and a plurality of concave portions and convex portions are formed on the uneven structure 68 at intervals in the height direction of the first fixing member 52.
By forming the concave-convex structure 68 on the outer side surface of the upper side surface portion 66 of the first fixing member 52, the bolt and nut fixation is performed using the spacer 86 formed with the same concave-convex structure 87 (see fig. 6), whereby the fixing strength between the first fixing member 52 and another member (the second fixing member 54) can be improved.
(14) The second stationary member 54 has a second lower portion 69 and a second upper portion 70. The second upper portion 70 of the second fixing member 54 has a plate-like portion 76, the plate-like portion 76 extending in the width direction of the second fixing member 54, and an uneven structure 77 on the lower surface of the plate-like portion 76, the uneven structure 77 having a plurality of recesses and projections formed at intervals in the width direction of the second fixing member 54. The second lower portion 69 of the second fixing member 54 has: a second bushing portion 72, the second bushing portion 72 defining a second axis 53; and a pair of second inclined surface portions 73, the pair of second inclined surface portions 73, 73 extending from the lower surface of the plate-like portion 76 toward the second boss portion 72, a central axis (second axis 53) of the second boss portion 72 being arranged parallel to a line bisecting the second upper portion 70 in the width direction, and the second lower portion 69 having a shape symmetrical with respect to the width direction.
By connecting the second fixing member 54 from the second upper portion 70 (plate-like portion 76) to the second boss portion 72 by the pair of second inclined surface portions 73, the second fixing member 54 is provided with a structure that is less likely to interfere with another member (the first fixing member 52) when the second fixing member 54 is inclined. Thus, the tilt range of the second fixing member 54 can be enlarged. Further, by providing the second fixing member 54 with a shape symmetrical with respect to the width direction, the center of gravity balance of the second fixing member 54 can be kept well.
(15) At least one second hollow portion 75 is formed in a region surrounded by the plate-like portion 76, the second boss portion 72, and the pair of second inclined surface portions 73, 73 of the second fixing member 54.
By forming the second hollow portion 75 in the second fixing member 54, the strength of the second fixing member 54 can be increased.
(16) The two structures are a frame structure of a mount for a solar panel and an installation surface side structure 1B.
Accordingly, the frame structure of the mount for a solar panel and the installation surface-side structure 1B can be fixed to each other so as to be inclined to each other, and the inclination in two directions can be coped with by a relatively simple structure as the mount for a solar panel.
(17) The first fixing member 52 and the second fixing member 54 are formed of an extruded profile made of an aluminum alloy.
As a result, the entire weight of the fixing member 10B can be reduced as compared with the case where each member is formed of a steel material. In addition, the dimensional accuracy of each member can be improved, the solar panel stand can be easily and accurately installed, and excellent corrosion resistance and appearance can be obtained. Further, since the aluminum alloy is excellent in recycling property, the materials of the first fixing member 52 and the second fixing member 54 can be reused after the solar panel mount is removed.
However, the fixing structure and the fixing member of the mount for a solar panel according to the present invention have been described by way of example of the above-described embodiment, but the present invention is not limited to the above-described embodiment, and various other embodiments may be adopted without departing from the scope of the present invention.
