JP 2013-144917 A

  In general, when a solar panel, for example, is installed as a functional panel on the roof surface of a building, it is desired that the number of solar panels installed on the roof surface is large in order to increase the total power generation amount. On the other hand, periodic maintenance is required for the roof surface and the solar panels installed on the roof surface. Therefore, when the number of installed solar panels is large, the amount of work such as removal of the solar panels at the time of maintenance has been great. In particular, when the back surface side of the solar panel is fixed with respect to the roof surface, it is difficult to access the back surface side of the solar panel, which is a fixed portion, and workability is reduced.

  An object of this invention is to provide the fixing member which can fix a functional panel so that the back side of a functional panel can be accessed easily.

  One embodiment of the present invention includes an upper surface portion or a bottom surface portion extending in one direction, a first side surface portion bent from one end in the width direction of the upper surface portion or the bottom surface portion, and other width directions of the upper surface portion or the bottom surface portion. A fixing member for fixing a functional panel above a cross member having a second side surface portion bent from the end and facing the first side surface portion, wherein the fixing member is fixed to the cross member; And a movable part fixed to the functional panel, and a shaft part that rotatably connects the fixed part and the movable part, wherein the axis of the shaft part is the second side surface part from the center in the width direction of the cross member. On the side, it is parallel to the extending direction of the cross member, and the fixing portion is provided with a fixing structure for abutting at least one of the upper surface portion and the first side surface portion of the cross member and fixing to the cross member. ing.

  According to such a fixing member, the functional panel can be tilted with the shaft portion as a fulcrum at a position closer to the second side surface than the center in the width direction of the cross member. It can be tilted by lifting the first side surface side from the center. In this case, by tilting the functional panel, it becomes easy to access the space on the back side of the functional panel. In particular, it becomes easy to access the upper surface portion and the first side surface portion side of the cross member to which the fixing portion is fixed.

  Moreover, the fixing | fixed part may have a contact part contact | abutted to the upper surface part of a cross member. Thereby, the fixing member is more stably fixed to the cross member.

  The contact portion extends at least beyond the second side surface portion in the width direction orthogonal to the extending direction of the cross member, and the movable portion is a shaft portion at a position exceeding the second side surface portion in the contact portion. May be connected to the fixed part. Since the contact portion connected to the movable portion is in contact with the upper surface portion of the cross member, the load of the functional panel applied to the movable portion can be stably supported. Moreover, since the shaft portion is disposed at a position beyond the second side surface portion, it is possible to suppress interference between the functional panel and the fixing member when the functional panel is tilted.

  The fixed portion includes a first abutting piece disposed on either the inner side or the outer side sandwiched between the first side surface portion and the second side surface portion and abutting on the first side surface portion, and a first abutting piece. And a second abutting piece that is disposed on one side and abuts against the second side surface portion. Thereby, since the fixing part of the fixing member comes into contact with and is supported by the first side surface part and the second side surface part of the cross member, the fixing member is prevented from falling.

  In addition, the vertical length of the first contact piece may be longer than the vertical length of the second contact piece. According to this, for example, when the vertical length of the first side surface portion of the cross member is longer than that of the second side surface portion, the fixing member can be supported more stably.

  The functional panel includes a panel main body and a frame portion provided on the outer periphery of the panel main body and protruding to a side where the cross member is disposed from the panel main body, and the movable portion is fixed to the frame portion. The shaft portion may be disposed closer to the panel body than the fixed position between the movable portion and the frame portion. In this way, the position of the functional panel can be lowered because the shaft portion is positioned closer to the panel body. Moreover, it becomes difficult to see the functional panel from the outside of the building, which is advantageous in terms of design.

  Further, the frame portion of the functional panel may be in contact with the upper surface portion of the cross member. When the frame portion of the functional panel is in direct contact with the cross member, the installation state of the functional panel is stabilized.

  According to the fixing member of the present invention, the functional panel can be fixed so that the back side of the functional panel can be easily accessed.

  Embodiments according to the present invention will be specifically described below with reference to the drawings. For convenience, the same reference numerals are given to substantially the same elements, and the description thereof may be omitted. In the following description, an example is shown in which the functional panel is fixed to the roof surface of the building, but the fixing position of the functional panel is not limited to the roof surface of the building.

(First embodiment)
As shown in FIG. 1, the building 1 is an industrialized house having a steel frame frame structure, and the frame is configured by a combination of structural members that have been standardized (standardized) in advance. In addition, although this embodiment demonstrates to an example the industrialized house provided with the frame of the steel frame ramen structure, a frame structure (pin brace structure) and a wooden frame may be sufficient. The building 1 has a predetermined planar module. The planar module means a basic dimension that serves as a design standard in architecture, and the building 1 is configured such that the planar dimension is an integral multiple of the planar module. The building 1 in this embodiment is a two-story building having a flat module of 305 mm, for example, and includes a solar panel (functional panel) 50 on a substantially flat land roof (roof) 3 serving as a rooftop. A veranda 5 is formed on the second floor, which is the lower floor of the flat roof 3. The building 1 in the illustrated example is built so that the front side faces the south side, and the solar panel 50 is provided to be inclined toward the south side.

  In the description of the present specification, “south side”, “north side”, “east side”, and “west side” do not strictly indicate just south, true north, true east, and true west. For example, if the south side is defined as “within ± 45 degrees south of azimuth” and the south side is the front, the side that faces the south side on the right side is the east side, the side that faces the east side is the west side, and the south side. The opposite side may be the north side. The definition of the south side is not limited to the above, and may include a wider range. Also, the north-south direction and the east-west direction do not follow a strict direction, and the direction connecting the south side and the north side as defined in this specification and the direction connecting the east side and the west side are defined as the north-south direction and the east-west direction. .

  FIG. 2 is a plan view of the building 1 showing the solar panel installation structure A1. In FIG. 2, the upper side of the drawing shows the north side, and the lower side, the right side, and the left side show the south side, the east side, and the west side, respectively. For convenience of explanation, the lower side in FIG. 2 may be the front and the upper side in FIG. 2 may be the rear. As shown in FIG. 2, a plurality of solar panels 50 are arranged on the flat roof 3 of the building 1. The flat roof 3 of the building 1 has a roof surface that is a rectangular region 3a having a substantially rectangular shape in plan view. The rectangular region 3 a is an inner side in a plan view of the parapet 6 formed along the outer peripheral edge 4 of the roof surface of the land roof 3.

  The outer peripheral edge 4 is the position of the intersection of the virtual vertical plane passing through the center of the outer peripheral beam 2a arranged along the outer periphery of the building 1 among the roof beams 2 constituting the frame of the building 1 and the roof surface. Assumed. The outer peripheral edge 4 is composed of a south end edge 4S which is an outer periphery on the south side, a north end edge 4N which is an outer periphery on the north side, an east end edge 4E which is an outer periphery on the east side, and a west end edge 4W which is an outer periphery on the west side. . A plurality of solar panels 50 are connected in the east-west direction to form a panel row R. In addition, the connection includes not only the case where adjacent solar panels 50 arranged in strict contact with each other but also the case where the solar panels 50 are arranged with a predetermined gap. Moreover, the panel row | line | column R forms the panel row | line group G by arrange | positioning in multiple steps at predetermined intervals in the north-south direction. The panel row R in the present embodiment is formed by six solar panels 50 connected in the east-west direction. Further, the panel row group G is formed by six stages of panel rows R arranged in the north-south direction. The connecting direction (in the east-west direction in the embodiment) of the plurality of solar panels 50 forming the panel row R is relative to the arrangement direction (in the north-south direction in the embodiment) of the plurality of panel rows R forming the panel row group G. Orthogonal.

  As described above, in the present embodiment, since the solar panels 50 are provided to be inclined, adjacent panel rows R are shaded by the shadows of the solar panels 50 (for example, at a point of 34 degrees north latitude in the winter season ( A shadow generated by sunlight of about 32 degrees, which is the south-mid altitude of the winter solstice), is arranged at a predetermined interval so as not to reach the solar panel 50 adjacent to the north side. The interval between the adjacent panel rows R is an east-west passage P1 extending in the east-west direction. That is, the panel row group G formed by the six-stage panel row R includes five east-west passages P1. Of the six rows of panel rows R, the panel row arranged on the most south side is the front end panel row (end panel row) Rf, and the panel row arranged on the most north side is the rear end panel row (end panel row). ) Rr. Between the front end panel row Rf and the rear end panel row Rr, four stages of panel rows R arranged in the north-south direction are arranged.

  An east-west passage P1 is formed between the four panel rows R arranged between the front end panel row Rf and the rear end panel row Rr. Further, an east-west passage P1 is formed between the front end panel row Rf and the panel row R on the north side of the front end panel row Rf. Further, an east-west passage P1 is formed between the rear end panel row Rr and the panel row R on the south side of the rear end panel row Rr.

  The front end panel row Rf is arranged along the south end edge 4S that is the outer peripheral edge on the south side of the rectangular region 3a. A width W1 between the front end panel row Rf and the south end edge 4S is formed to be smaller than the width W2 of the east-west passage P1. In this embodiment, the width W1 between the front end panel row Rf and the south end edge 4S is, for example, about 50 to 140 mm, and the width W2 of the east-west passage P1 is about 200 to 300 mm. Further, the rear end panel row Rr is arranged along the north end edge 4N that is the outer peripheral edge on the north side of the rectangular region 3a. A width W3 between the rear end panel row Rr and the north end edge 4N is formed to be smaller than the width W2 of the east-west passage P1. In the present embodiment, a width W3 between the rear end panel row Rr and the north end edge 4N is, for example, about 100 to 180 mm. The width W1 between the front end panel row Rf and the south end edge 4S is a horizontal distance from a virtual vertical plane passing through the south end edge 4S to the front end panel row Rf. The width W3 between the rear end panel row Rr and the north end edge 4N is a horizontal distance from an imaginary vertical plane passing through the north end edge 4N to the rear end panel row Rr. Thus, the solar panel 50 arrange | positioned at the land roof 3 can be increased by arrange | positioning the front-end panel row | line | column Rf and the rear-end panel row | line | column Rr close to the outer periphery 4.

  A north-south passage P2 extending in the north-south direction is formed between at least one side edge of the east side and west side edges of the panel row group G and the outer peripheral edge 4 of the rectangular region 3a. The north-south passage P2 communicates with the east-west passage P1. Therefore, by passing through the north-south passage P2, it is possible to easily move from one east-west passage P1 to another east-west passage P1. In the present embodiment, the side edge GW on the west side of the panel row group G substantially coincides with the west end edge 4W that is the outer peripheral edge on the west side in plan view. On the other hand, the east side edge GE of the panel row group G is disposed at a predetermined interval from the east end edge 4E which is the east side outer peripheral edge. The north-south passage P2 is formed by the distance between the east side edge GE of the panel row group G and the east end edge 4E. The width W4 of the north-south passage P2 in the present embodiment is formed wider than the width of the east-west passage P1, and is formed to have a width of about 250 to 600 mm, for example. The width W4 of the north-south passage P2 is a horizontal distance from the east side edge of the panel row group G to a virtual vertical plane passing through the east end edge 4E.

  The flat roof 3 is provided with elevating means that leads from the north-south passage P2 down to the floor. In the present embodiment, a ladder La (see FIG. 1) is provided at the east end edge 4E of the flat roof 3 so as to be connected to the downstairs beyond the parapet 6. The ladder La may be permanently installed, but is usually removable with respect to the installable structure formed on the flat roof 3 or the outer wall surface, and is prepared by an operator at the time of maintenance. In the embodiment, a hook as an installable structure is provided on the land roof 3, and the upper end of the ladder La can be attached to the hook. Note that the installable structure is not limited to the hook, but may have a structure for attaching the upper end of the ladder. The lower end of this ladder is connected to, for example, an empty space SP on the ground. Moreover, the ladder (illustration omitted) connected to the veranda 5 may be used as a raising / lowering means connected to the downstairs from the north-south passage P2. For example, an openable door can be provided on the floor of the north-south passage P2 located above the veranda 5, and a ladder connected to the veranda 5 can be installed below the door. Thus, by installing the ladder La leading from the north-south passage P2 to the downstairs, the operator can easily access all five east-west passages P1 from the ladder La via the north-south passage P2.

  Next, the structure for fixing the solar panel 50 to the flat roof 3 will be described in detail with reference to FIGS. As shown in FIGS. 3 and 4, the solar panel 50 is attached to the gantry 30, and the gantry 30 is fixed to and supported by the column base 20. The column base 20 is fixed above the roof beam 2 constituting the frame of the building 1 and protrudes on the land roof 3. The roof beam 2 in the present embodiment has an outer peripheral beam 2a disposed along the outer peripheral edge 4, and a column base 20 is disposed above the outer peripheral beam 2a.

  As shown in FIG. 6, the flat roof 3 includes a floor panel 11 supported by the roof beam 2, a heat insulating material 12 disposed on the upper surface side of the floor panel 11, and a board 13 disposed on the upper side of the heat insulating material 12. And a waterproof sheet 14 attached to the upper surface of the board 13. The floor panel 11 is formed by an ALC panel, for example. A mortar 16 is placed between the floor panel 11 and the outer wall panel 15.

  A waterproof steel plate 18 is provided on the outer periphery of the flat roof 3. The waterproof steel plate 18 covers the inside from the upper end of the outer wall panel 15 forming the parapet 6 along the shape of the parapet 6, and further covers the outer periphery of the roof surface of the land roof 3 with a predetermined width. The inner peripheral edge of the waterproof steel plate 18 is covered with the waterproof sheet 14.

  As shown in FIG. 3, at least a part of the column base 20 (for example, the column base 20 arranged at both ends in the north-south direction) is fixed to the outer peripheral beam 2 a constituting the roof beam 2. Thus, by arranging the column base 20 above the outer peripheral beam 2a, it is possible to install the solar panel 50 up to the most outward position of the roof surface within a range where the center of gravity does not go out.

  In addition, as shown in FIG. 2, a column base 20 is disposed on the flat roof 3 at the center of the building 1 in the north-south direction. A beam extending in the east-west direction as a part of the roof beam 2 is formed below the column base 20. The roof beam 2 has a beam extending in the east-west direction including the outer peripheral beam 2a and a pair of beams extending in the north-south direction at the west and east side edges, and the beam extending in the east-west direction and the beam extending in the north-south direction are mutually Orthogonal. The column base 20 supported by the beam extending in the east-west direction is fixed at a position at least one plane module away from the beam extending in the north-south direction. For example, the column base 20W fixed to the most west side is fixed at a position one plane module away from the beam extending in the north-south direction on the west side, and the column base 20E fixed to the east side is the north-south direction on the east side. It is fixed at a position two modules away from the beam extending in the direction. That is, the column base 20 is not fixed above the west and east beams extending from north to south.

  The column base 20 is a member for supporting the gantry 30 on the flat roof 3. The column base 20 has a column head unit 21, a column base unit 22, and a connection unit 23. The stigma unit 21 has a cylindrical leg portion 21a attached to the pedestal unit 22, and a plate-like support portion 21b joined to the upper end of the leg portion 21a for fixing the joint hardware 41. . The column base unit 22 includes a bottom plate 22a that is joined to the upper flange of the outer peripheral beam 2a, an intermediate portion 22b that is formed in a cross shape in plan view, and an upper plate 22c that is joined to the upper end of the intermediate portion 22b. These are integrally welded. The connection unit 23 is a member for connecting the column head unit 21 and the column base unit 22, and includes a plate-like bottom plate 23 a and a cylindrical connection portion 23 b joined to the upper surface of the bottom plate 23 a. The upper flange of the outer peripheral beam 2a and the bottom plate 22a of the column base unit 22 are joined together by, for example, bolts and nuts. Further, the upper plate 22c of the column base unit 22 and the bottom plate 23a of the connecting unit 23 are joined together by, for example, bolts and nuts. Furthermore, the lower end of the leg portion 21a of the stigma unit 21 is attached to the connecting portion 23b. For example, a groove is formed on the inner peripheral surface of the connecting portion 23b and the outer peripheral surface of the lower end of the leg portion 21a so as to be screwed to each other, thereby joining the connecting portion 23b and the leg portion 21a. In the illustrated example, the height of the intermediate portion 22b is substantially the same as the height of the floor panel 11. The leg portion 21 a projects through the through hole 25 formed in the heat insulating material 12 and the waterproof steel plate 18 and projects upward from the land roof 3. A water stop treatment is applied to the boundary between the leg portion 21a and the waterproof steel plate 18.

  The gantry 30 (see FIG. 2) includes a cross member 34 and a vertical member 31. The cross member 34 extends with the east-west direction, which is the connecting direction of the panel rows R, as the longitudinal direction. The longitudinal member 31 extends with the north-south direction intersecting the longitudinal direction of the transverse member 34 as the longitudinal direction. In the present embodiment, since the solar panels 50 are disposed so as to be inclined in the north-south direction, the cross members 34 extend so as to intersect perpendicularly to the inclination direction of the solar panels 50. The solar panel 50 is supported by the cross member 34, and the cross member 34 is supported by the column base 20 via the vertical member 31. It is also possible to directly support the cross member 34 with the column base 20. However, the number of the column bases 20 can be reduced by interposing the highly rigid vertical member 31 as in the present embodiment. As a result, the construction becomes easier as compared with the aspect in which the cross member 34 is directly supported by the column base 20.

  The gantry 30 is fixed to the column base 20 via a joint hardware 41. The joint hardware 41 (see FIG. 5) is a plate-shaped member having a substantially U-shaped cross section, and includes a rectangular plate-shaped bottom surface portion 41a, a side surface portion 41b erected from one end of the bottom surface portion 41a, and a side surface portion 41b. And a plate-like upper surface portion 41c extending horizontally at the upper end. The joint hardware 41 is fixed to the column base 20 by fixing the bottom surface portion 41 a to the support portion 21 b of the column base 20 with a bolt 42 a and a nut 42 b. The side surface portion 41b having a rectangular plate shape that is long in the horizontal direction is formed with insertion holes 41d for fixing the vertical members 31 to both ends in the longitudinal direction.

  The longitudinal member 31 (see FIG. 3) is fixed to the flat roof 3 so that both ends thereof are fixed to the joint hardware 41 so as to extend from north to south. The vertical member 31 (see FIG. 5) is a long member having a substantially U-shaped cross section, a plate-like bottom surface portion 31a, a side surface portion 31b standing from one end of the bottom surface portion 31a, and an upper end of the side surface portion 31b. And a plate-like upper surface portion 31c extending horizontally. In addition, ribs 31d and 31e that protrude downward and extend in the longitudinal direction are formed at the ends of the bottom surface portion 31a and the upper surface portion 31c opposite to the side surface portion 31b.

  The vertical member 31 is supported by the upper surface portion 41c of the joint hardware 41 on one end side in the longitudinal direction of the joint hardware 41, and the side surface portion 31b of the side metal portion 41b is connected to the side surface portion 41b of the joint hardware 41 by bolts 44a and nuts 44b. Fixed. Similarly, in the vertical member 31, the other end is fixed to a joint hardware 41 fixed to another column base 20. In the present embodiment, as shown in FIG. 2, two vertical members 31 are connected and extend in the north-south direction. One longitudinal member 31 is supported by the column base 20 fixed respectively above the outer peripheral beam 2a on the south side and above the central roof beam 2 in the north-south direction. The other vertical member 31 is supported by the column base 20 fixed to the upper side of the outer peripheral beam 2a on the north side and the upper side of the central roof beam 2 in the north-south direction.

  In addition, in the joint hardware 41 fixed to the outer peripheral side of the flat roof 3, only the insertion hole 41d on the one end side in the longitudinal direction is used. Therefore, in the joint hardware 41, the edge on the side (outside) where the unused insertion hole 41d is formed may be processed into a predetermined shape. For example, the side of the joint hardware 41 where the unused insertion hole is formed is connected to the roof periphery (the upper end of the parapet 6) and the solar panel 50 at the shortest distance from this periphery. You may form so that it may fit in the side. In this case, when the building 1 is looked up from the ground, the joint hardware 41 cannot be visually recognized unless the solar panel 50 is visible, so that the design of the entire building 1 is improved.

  In addition, it is also possible to fix the vertical member 31 directly to the column base 20 without providing the joint hardware 41. However, the vertical member 31 needs a certain height in order to secure a desired strength. When the vertical member 31 is fixed directly to the column base 20, the height of the solar panel 50 increases. Therefore, there is a possibility that it may be easily affected by the oblique line regulation and the appearance design may be deteriorated. By using the joint hardware 41 as in the present embodiment, the height position of the vertical member 31 with respect to the column base 20 can be adjusted. As a result, the strength of the vertical member 31 is ensured while suppressing the height of the solar panel 50. It becomes easy to plan.

  The cross member 34 (refer to FIG. 2) is fixed to the land roof 3 so as to extend in the east-west direction by being installed on the plurality of vertical members 31. In the present embodiment, cross members 34 are used on the front side and the rear side below each panel row R, and these cross members 34 are longitudinal members 31 at predetermined intervals according to the size of the solar panel 50. It is fixed to. In addition, the rear side member 34 corresponding to one panel row R and the front side member 34 of the panel row R arranged on the north side of the panel row R are arranged at a certain interval.

  The cross member 34 (see FIGS. 6 and 10) is a long member having a hat-shaped cross section, and is opposed to the front side wall part (second side part) 34b erected along the longitudinal direction and the front side wall part 34b. It has the rear side wall part (1st side part) 34c arrange | positioned, and the upper wall part (upper surface part) 34a which connects the upper end of the front side wall part 34b and the rear side wall part 34c. In other words, the cross member 34 includes an upper wall portion 34a extending in the longitudinal direction, a front side wall portion 34b bent from one end (front end) in the width direction perpendicular to the longitudinal direction of the upper wall portion 34a, and an upper wall portion. And a rear side wall part 34c bent from the other end (rear end) in the width direction. A base portion 34d extending outward is formed at the lower ends of the front side wall portion 34b and the rear side wall portion 34c. The upper wall portion 34a faces the back surface of the solar panel 50, and is inclined so as to descend to the front side (south side) so as to be substantially the same angle as the installation angle of the solar panel 50. Moreover, the front side wall part 34b is arrange | positioned at the downward direction of the inclination direction, and the rear side wall part 34c is arrange | positioned at the upper direction of the inclination direction. In the present embodiment, the inclination of the upper wall portion 34a is, for example, about 10 degrees. The base portion 34d of the cross member 34 is fixed to the upper surface portion 31c of the plurality of vertical members 31 by bolts 35a and nuts 35b. Since the cross member 34 and the vertical member 31 are fixed in contact with each other by the base portion 34d and the upper surface portion 31c, they are stably fixed. By adjusting the inclination of the upper wall portion 34a to the installation angle of the solar panel 50, the solar panel 50 can be received by the surface, and more stable installation is possible.

  The rear end edge portion (inner edge portion facing the other panel row R adjacent to the north side) 50b and the front end edge portion closer to the lower side in the inclination direction (upward in the inclination direction in the solar panel 50 of the front end panel row Rf) The outer edge part 50a opposite to the inner edge part 50a is fixed to the cross member 34 arranged along each of them. A hinge portion (fixing member) 60 is provided at the front end edge portion 50a of the solar panel 50 in the front end panel row Rf. The solar panel 50 is detachably attached to the cross member 34 of the gantry 30 via the hinge part 60. The hinge portion 60 includes a fastening portion 65 that can be removed from the north side east-west passage P1 side. This removal operation is a tightening / releasing operation of the fastening portion 65, that is, an operation that can be fixed by tightening the fastening portion 65 and can be removed by loosening.

It is arranged on the panel part 51 side with respect to the connecting piece 63a that is a fixed position between the frame 63 and the frame part 53. Thus, the arrangement position of the solar panel 50 can be lowered because the shaft part 62 is located close to the panel part 51 side. Moreover, it becomes difficult to see the solar panel 50 from the outside of the building 1, which is advantageous in terms of design. Moreover, the installation state of the solar panel 50 is stabilized by the frame part 53 of the solar panel 50 being in contact with the upper wall part 34a of the cross member 34.

  Moreover, since the hinge part 60 is installed in the south outer periphery of the building 1, the front edge part 50a of the solar panel 50 located in the south outer periphery of the building 1 is close to the roof surface of the building 1. Therefore, even if wind blows from the south side of the building 1, the force to blow up the solar panel 50 due to the wind exceeding the outer periphery of the south end of the building 1 does not easily act on the solar panel 50. Installation status is more stable.
