Description

  The present invention relates to a structure for mounting a functional panel having a specific function such as a solar cell module or a solar hot water panel on a roof.

  One method of attaching a functional panel such as a solar cell module on a roof is a method of attaching a functional panel to an existing roof formed by spreading ceramic tiles.

In this construction method, first of all, a plurality of existing roof tiles 5 sown on the roof, the roof tiles 5 at predetermined locations are removed, and the support tiles 6 are attached to the removed locations. The supporting roof 6 supports and attaches the vertical beam 1 that is long in the eaves-ridge direction. Then, after attaching a plurality of vertical bars 1, a horizontal beam 2 is stretched over the vertical beam 1 and the horizontal beam 2 is coupled to the vertical beam 1 to form the frame 3. Next, a plurality of functional panels 4 are fixed to the gantry 3 by fitting and attaching the functional panels 4 between the adjacent horizontal rails 2. In this manner, a plurality of functional panels 4 can be attached to the roof while being supported by the gantry 3 (see FIGS. 3 and 10 to 12, for example, see Patent Document 1).
JP 11-324259 A

  As described above, the frame 3 formed by assembling the vertical beam 1 and the horizontal beam 2 is supported on the roof by the supporting tile 6, and when attaching a plurality of functional panels 4 to the frame 3, the functional panel 4 is a roof eave. Arranged in multiple stages in the building direction (inclination direction of the roof). At this time, when the roof has a square planar shape like a gable roof, as shown in FIG. Can be mounted in an arrangement in which the number of upper and lower steps is the same, and the overall shape is rectangular.

  On the other hand, when the roof has a trapezoidal or triangular planar shape like a dormitory roof, as shown in FIG. 11 and FIG. It is necessary to install in the arrangement to gather. Thus, when forming in the arrangement which gathers in a triangle or trapezoid as a whole, it is functional panel 4 to make what is called a staggered arrangement which arranges functional panel 4 of the upper stage side so that it may straddle between adjacent functional panels 4 of the lower stage side. This is preferable because the number of the installed can be increased.

  However, when the functional panels 4 are arranged in a staggered manner as shown in FIG. 11 and FIG. 12, the functional panels 4 are not aligned in the eaves ridge direction at the upper and lower stages, so that they extend over a plurality of stages as in the case of FIG. The lengthwise vertical rail 1 cannot be used. Accordingly, it is necessary to use a large number of the vertical bars 1 having the length of one functional panel 4 and to use a large number of supporting tiles 6 according to the number of the vertical bars 1.

  For example, in the case of FIG. 11 in which six functional panels 4 are arranged in a staggered manner in the order of 3, 2, 1 from the bottom, the number of vertical bars 1 is 8 and the number of support tiles 6 is 16. is there. In addition, in the case of FIG. 12 in which twelve functional panels 4 are arranged in a staggered manner in order of 5, 4, 3 from the bottom, 14 vertical bars 1 and 28 support tiles 6 are required. is there. In this way, when the functional panels 4 are arranged in a staggered manner, it is necessary to replace a large number of supporting tiles 6 on the roof and attach a large number of vertical rails 1, and the construction cost increases due to an increase in the number of parts and construction time. There was a problem of fear.

  The present invention has been made in view of the above points, and in mounting the functional panels in a staggered manner, the number of vertical rails and the number of supporting tiles can be reduced, and the construction cost can be reduced. The object is to provide a panel mounting structure.

  In the functional panel mounting structure according to claim 1 of the present invention, among the roof tiles 5 installed on the roof, the roof tile 5 at a predetermined location is replaced with the support tile 6 and fixed to the support tile 6. A plurality of vertical beams 1 in the eaves ridge direction are arranged in parallel, and a plurality of horizontal beams 2 are attached in parallel by spanning over the vertical beams 1 to mount the frame 3 composed of the vertical beams 1 and the horizontal beams 2 on the roof. Installed on top and arranged in multiple stages in the direction of the eaves ridge, and placed so that the upper functional panel 4 straddles between adjacent functional panels 4 on the lower side, the number of the upper side from the lower side In the functional panel mounting structure in which a plurality of functional panels 4 are mounted on the roof by fixing the functional panel 4 to the gantry 3 with an arrangement in which the number of functional panels 4 is reduced. Short vertical beam 1 with a length approximately equal to the dimension in the building direction And a long vertical beam 1b having a length substantially equal to an integral multiple of the dimension of the functional panel 4 in the eaves direction, and the short vertical beam 1a at the position where the functional panel 4 is arranged at the lower end. The long vertical rail 1b is fixed to the support tile 6 at a position where the functional panel 4 is arranged on each of the upper and lower stages, while being fixed to the support tile 6.

  The invention of claim 2 uses a plurality of types of horizontal rails 2 having different lengths as in the first aspect, and provides coupling holes 7 at a plurality of locations in the longitudinal direction of the horizontal rails 2. The horizontal beam 2 is coupled and fixed to the vertical beam 1 by a bolt 8 that is passed through.

  According to the present invention, when the functional panels 4 are mounted in a staggered arrangement, the lengths of the functional panels 4 are approximately equal to an integral multiple of the dimension of the functional panels 4 in the eaves-ridge direction at the positions where the functional panels 4 are disposed at the upper and lower stages. Since the long vertical beam 1b is fixed to the support tile 6, the number of the vertical beams 1 can be reduced and the number of the support tiles 6 supporting the vertical beam 1 can be reduced. Yes, the construction cost can be reduced.

  Hereinafter, the best mode for carrying out the present invention will be described.

  An embodiment of a method for attaching a functional panel 4 to a roof of an existing ceramic tile by using a solar cell module as the functional panel 4 will be described. First, among the existing roof tiles 5 laid on the roof, the roof tiles 5 at predetermined locations are removed, and the support tiles 6 are attached to the removed locations. FIGS. 1 and 2 show the arrangement of the roof tiles 5. The roof tiles 5 are removed from the places necessary to fix the vertical rails 1 constituting the gantry 3 and the supporting tiles 6 (FIGS. And the above-described FIGS. 10 to 12 (shown by hatching).

  The support tile 6 is formed of a ceramic tile in substantially the same shape as the roof tile 5, and a bracket receiver 19 is integrally projected on the upper surface of the support tile 6 as shown in FIGS. 3 and 4. . A lower fixing bracket 20 is attached to the bracket receiver 19. The lower fixing bracket 20 can be attached to the bracket receiver 19 by screwing the lower fixing piece 21 provided on the lower fixing bracket 20 so as to protrude from the lower surface and the bracket receiver 19 through bolts and nuts 22. .

  The gantry 3 is formed by assembling a plurality of vertical bars 1 and horizontal bars 2 made of a metal material such as aluminum. The vertical rail 1 is formed in a hollow cylindrical shape, and a slide groove 11 is provided on the upper surface thereof over the entire length in the longitudinal direction, and relative to both sides of the opening edge of the upper surface of the slide groove 11. The locking pieces 12 are provided so as to project in an integrated manner. Furthermore, a fixing groove 25 is formed in the lower part of both side surfaces of the vertical beam 1 and opens laterally over the entire length (see FIG. 6B). Further, the cross rail 2 is formed in a U-shaped cross-section with an open upper surface, and receiving pieces 26 are provided integrally on both sides of the lower end so as to project sideways over the entire length. Further, in the center in the width direction of the bottom of the horizontal rail 2, a coupling hole 7 is formed at a location where it is coupled to the vertical rail 1 (see FIG. 6A).

  When assembling the gantry 3 using the vertical beam 1 and the horizontal beam 2, the vertical beam 1 is attached to the roof in the eaves direction, and first, the vertical beam 1 is arranged along the eaves direction. The vertical rail 1 is attached to and fixed to the support tile 6 by the lower fixing bracket 20. As shown in FIG. 4, a pair of parallel upper fixing pieces 23 are provided on the upper surface of the lower fixing bracket 20, and attachment holes 24 are formed in each upper fixing piece 23. Then, the vertical beam 1 is placed on the lower fixing bracket 20 while being fitted between the upper fixing pieces 23, and the upper fixing piece 23 and the vertical beam 1 are bolted to each other, so that the lower fixing bracket 20 and the metal fittings are mounted. The vertical rail 1 can be fixed and mounted on the support tile 6 by the support 19. Here, as shown in FIG. 4A, holes (not shown) are provided in the fixing grooves 25 on both sides of the vertical rail 1 at the eaves side end portion of the vertical rail 1, and the bolt 27 is attached to the upper fixing piece 23. The vertical beam 1 is fixed to the lower fixing bracket 20 by screwing the nut 28 through the mounting hole 24 of the vertical beam 1 and this hole of the vertical beam 1. As shown in b), nuts 28 are inserted into the fixing grooves 25 on both sides of the vertical beam 1 and attached, and a pair of bolts 27 are threaded into the nuts 28 through the attachment holes 24 of the upper fixing pieces 23. By doing so, the vertical rail 1 is fixed to the lower fixing bracket 20.

  After the plurality of vertical beams 1 are arranged in the direction of the eaves and attached to the support tile 6 as described above, the horizontal beam 2 is arranged in a direction parallel to the eaves (or buildings) and placed on the vertical beam 1. It crosses at right angles and joins the horizontal beam 2 to the vertical beam 1. A plate nut 13 is used for this connection. As shown in FIG. 5, the plate nut 13 is formed by making a screw hole 14 in an elongated rectangular plate and bending and projecting a positioning protrusion 15 upward at one end in the longitudinal direction. The width dimension of the plate nut 13 is formed to be substantially the same dimension (slightly smaller) as the groove width of the slide groove 11 of the vertical beam 1, and the width dimension of the positioning protrusion 15 is the distance between the opposed tips of the locking pieces 12. It is formed smaller than the dimensions. Further, the distance between the inner surface of the positioning protrusion 15 of the plate nut 13 and the screw hole 14 (hole center) is the distance between the tip of the receiving piece 26 of the horizontal rail 2 and the coupling hole 7 (hole center). The plate nut 13 is manufactured so as to be substantially equal to the above. Then, as shown in FIG. 5, the plate nut 13 is inserted into the slide groove 11 from the end of the vertical beam 1, and the plate nut 13 is moved along the slide groove 11 to a position where the horizontal beam 2 is coupled on the vertical beam 1. Move the slide. In this state where the plate nut 13 is inserted into the slide groove 11, the positioning protrusion 15 of the plate nut 13 protrudes upward from the gap between the tips of the locking pieces 12, and the plate nut 13 is slid to the horizontal rail. When the inner surface of the positioning projection 15 is brought into contact with the tip of the receiving piece 26 of the horizontal beam 2, the screw hole 14 of the plate nut 13 is positioned directly below the coupling hole 7 of the horizontal beam 2. The coupling hole 7 and the screw hole 14 can be aligned. Accordingly, with the positioning projection 15 of the plate nut 13 in contact with the receiving piece 26 of the horizontal beam 2, the bolt 8 is inserted into the coupling hole 7 of the horizontal beam 2 from above, as shown in FIG. The bolt 8 can be screwed into the hole 14, and by tightening the bolt 8, the locking piece 12 of the vertical beam 1 is held between the lower surface of the horizontal beam 2 and the plate nut 13, and the vertical beam 1 The crosspiece 2 can be attached on the top.

  In this way, by mounting a plurality of horizontal beams 2 orthogonally on a plurality of vertical beams 1, a plurality of vertical beams 1 in the eave building direction and a plurality of horizontal beams parallel to the eaves (or building). 2 can be formed, and the gantry 3 is supported on the roof by a supporting tile 6. In FIG. 3, 33 is a vertical beam cap attached to the ridge side end of the vertical beam 1, and 34 is a horizontal beam cap attached to both ends of the horizontal beam 2.

  In the present invention, the functional panel 4 is not particularly limited, but a solar cell module can be used. The solar cell module is formed in a rectangular plate shape by arranging a plurality of solar cells in a matrix, and as shown in FIG. The frame 16 is integrally provided with an engagement piece 35 that is bent and protrudes in an L-shaped cross section.

  When attaching the functional panel 4 to the gantry 3, first, the functional panel 4 is fitted between the adjacent horizontal rails 2, and the ends of the functional panel 4 on the eaves side and the ridge side are placed on the receiving pieces 26 of the horizontal rails 2. Placed on. Here, a locking bolt 40 is attached to each horizontal rail 2 as shown in FIG. The locking bolt 40 is formed by standing a bolt 42 on the upper surface of a rectangular slide plate 41, and slide locking grooves so as to face each inner surface of both edges of the upper surface opening of the horizontal rail 2. 43 is provided over the entire length in the longitudinal direction. By sliding the slide plate 41 in the longitudinal direction of the horizontal beam 2 with both ends of the slide plate 41 inserted and locked in the slide locking groove 43, the bolt 42 is attached to the horizontal beam 2 at an arbitrary position of the horizontal beam 2. The locking bolt 40 can be attached to the horizontal rail 2 in a state of protruding upward.

  Next, the cover plate 45 is attached on the horizontal rail 2. The cover plate 45 is provided with engagement pressing pieces 46 bent downward on both side ends, and through holes 47 are provided at predetermined intervals. The cover plate 45 is formed by inserting the bolts 42 of the locking bolts 40 into the through holes 47. When 45 is put on the horizontal beam 2, each engagement pressing piece 46 of the cover plate 45 is engaged with the engagement piece 35 of the outer frame 16 of each adjacent functional panel 4 via the horizontal beam 2. It has become. Then, a nut 49 such as a cap nut is screwed into the bolt 42 of the locking bolt 40 and tightened. The function panel 4 can be fixed to the crosspiece 2 while being pressed by 45, and the function panel 4 can be attached to the gantry 3.

  In FIG. 3, 51 is an eaves cover plate, and 52 is a ridge cover plate. As in the case of the cover plate 45, the locking bolt 40 and the nut are engaged with the engaging piece 35 of the functional panel 4. 49 is attached to the horizontal beam 2 located at the eave side end and the horizontal beam 2 located at the ridge side end. An earth washer 54 is attached to the horizontal rail 2 located between the adjacent functional panels 4. The ground washer 54 is formed of a metal plate, and is provided with an inverted trapezoidal bar contact piece 55 bent downward at the two opposite ends, and a functional panel contact piece at the other two opposite ends. 56 is formed by bending downward. Then, when the through hole 57 provided in the ground washer 54 is inserted into the bolt 42 of the locking bolt 40 attached to the horizontal rail 2 and the ground washer 54 is disposed so as to straddle the horizontal rail 2, each of the ground washers 54 is arranged. The crosspiece contact piece 55 fits into and comes into contact with the upper surface opening of the horizontal crosspiece 2, and each functional panel contact piece 56 is inside the engagement piece 35 of the outer frame 16 of each functional panel 4 adjacent to the horizontal crosspiece 2. Into and touch. By fixing the cover plate 45 from above the earth washer 54 as shown in FIG. 7B, the functional panel 4 is attached to the gantry 2 with the earth washer 54. Can be performed.

  When attaching a plurality of functional panels 4 to the gantry 3 formed by assembling the vertical beam 1 and the horizontal beam 2 as described above, the functional panels 4 are arranged in a plurality of stages along the eave building direction (the inclination direction of the roof). However, when the roof has a trapezoidal or triangular planar shape like a dormitory roof, as shown in FIG. 1 and FIG. By shifting the position of the functional panel 4 by half the width of the functional panel 4, the upper functional panel 4 is arranged so as to straddle between the adjacent functional panels 4 on the lower stage. The functional panel 4 is attached to the gantry 3 in a staggered arrangement so that the upper side is one less than the lower side. Therefore, the function panel 4 located at the end of the lower step in the step adjacent to the upper and lower sides protrudes to the side with a half width of the function panel 4 located at the end of the upper step. become.

  In the present invention, when the functional panel 4 is attached to the gantry 3 in the staggered arrangement as described above, the vertical rail 1 constituting the gantry 3 is a short having a length substantially equal to the vertical dimension (dimension in the eave building direction) of the functional panel 4. A long vertical bar 1a and a long vertical bar 1b having a length substantially equal to an integral multiple of the vertical dimension of the function panel 4 are used. The length of the long vertical bar 1b is preferably set to a length that is an integral multiple of the vertical dimension of the functional panel 4 by the number corresponding to the number of stages of the functional panel 4 installed on the roof. If the length of the long vertical bar 1b is too long, it may be shorter than this. In addition, the length of the short vertical beam 1a or the long vertical beam 1b is precisely the dimension obtained by multiplying the vertical dimension of the function panel 4 by an integer, and is mounted on the short vertical beam 1a or the long vertical beam 1b. This is a dimension obtained by adding the width dimension of the horizontal beam 2 to be mounted (not including the protruding dimension of the receiving piece 26) to the number of attachments.

  As shown in FIG. 1 and FIG. 2, the functional panel 4 arranged at the end of the lower stage is a part of the part protruding sideward from the functional panel 4 at the end of the stage adjacent to the upper side of this stage In the embodiment of FIG. 1 or FIG. 2, the short vertical beam 1a is arranged at the position of the outer end of the functional panel 4 arranged at the end in the first and second stages from the bottom, The support tile 6 is attached as shown in FIG. Further, a long vertical rail 1b is arranged at a position where the functional panel 4 is arranged on each of the upper and lower stages, and is attached to the support tile 6.

  After attaching the short vertical beam 1a and the long vertical beam 1b in this way, the horizontal beam 2 is arranged over the short vertical beam 1a and the long vertical beam 1b and the long vertical beam 1b, The horizontal beam 2 is joined to the short vertical beam 1a and the long vertical beam 1b as shown in FIG. The horizontal beam 2 is arranged along the lower edge and upper edge of each stage where the functional panel 4 is installed. The horizontal beam 2 is connected to the short vertical beam 1a and the long vertical beam 1b, and the frame 3 is attached. Assemble. Thereafter, the functional panel 4 is arranged between the adjacent horizontal rails 2 and the functional panel 4 is fixed to the horizontal rails 2 as shown in FIG. 7, so that the functional panel 4 as shown by a chain line in FIG. Can be arranged in a zigzag arrangement that gathers in a triangular shape as a whole, and as shown by a chain line in FIG. Is.

  Here, as the horizontal beam 2, a plurality of types having different lengths are used. For example, as shown in FIG. 8A, the horizontal beam 2a having the same dimensions as the horizontal width of the functional panel 4 is used. ), The horizontal beam 2b having a size 1.5 times the horizontal width of the functional panel 4, and the horizontal beam 2c having a size twice the horizontal width of the functional panel 4 as shown in FIG. 8C. 2 is used. When the six functional panels 4 are attached in a zigzag arrangement that gathers in a triangular shape as a whole as shown in FIG. 1, there is a horizontal rail between the first eave side edge and the first and second tiers from the bottom. Two 2b are connected and used. One horizontal beam 2c is used between the second and third stages, and one horizontal beam 2a is used at the third ridge side edge. In addition, when twelve functional panels 4 are mounted in a staggered manner as a whole as shown in FIG. 2, the horizontal eaves between the first eave side edge and the first and second tiers from the bottom are shown. 2c is used by connecting a horizontal beam 2b to each end of the 2c, and two horizontal beams 2c are connected between the second and third stages, and a horizontal beam 2b is used at the third ridge side edge. Two are connected and used. Thus, by using different horizontal rails 2 of different lengths, the degree of freedom of arrangement of the vertical rails 1 is increased according to the number of function panels 4 installed. It is easy to reduce the number.

  When the horizontal beam 2 is mounted on the vertical beam 1 as described above, the distance between the short vertical beam 1a and the long vertical beam 1b varies depending on the number and arrangement of the function panels 4. The coupling hole 7 provided in the horizontal beam 2 to couple the horizontal beam 2 to the vertical beam 1 is adapted to the interval between the short vertical beam 1a and the long vertical beam 1b arranged according to the number of function panels 4 installed. As shown in FIGS. 8A, 8B, and 8C, it is formed at a plurality of locations. Of the crosspieces 2, the crosspieces 2 a and 2 c may connect the connected butted portions to the vertical crosspiece 1 (see FIG. 2), so that a semicircular coupling hole 7 is formed at one end of the crosspieces 2 b and 2 c. Is formed. The coupling holes 7 other than the coupling hole 7 at the end are formed as long holes that are long in the longitudinal direction in order to absorb alignment errors between the vertical beam 1 and the horizontal beam 2.

  Further, when connecting the crosspieces 2 as described above, a crosspiece joint 59 having a U-shaped cross section as shown in FIG. 9A is used. That is, the horizontal beam joint 59 is inserted into each horizontal beam 2 to be connected, the end surfaces in the longitudinal direction of each horizontal beam 2 are butted, and then the horizontal beam 2 is connected from the connection hole 60 provided in the horizontal beam joint 59. The bolts 61 are inserted into the connecting holes 7 and the nuts 62 are screwed into the tip portions of the bolts 61, thereby connecting the pair of horizontal beams 2 in the longitudinal direction by the horizontal beam joints 59 as shown in FIG. 9B. It is something that can be done.

  When mounting the functional panels 4 in a zigzag manner as described above, the length of the length approximately equal to an integral multiple of the dimension of the functional panel 4 in the eave building direction at the position where the functional panels 4 are arranged at the upper and lower stages. Since the vertical bars 1b are used, the number of vertical bars 1 can be reduced, and the number of supporting tiles 6 that support the vertical bars 1 can be reduced. For example, as shown in FIG. 1, when six functional panels 4 are installed in a zigzag arrangement that gathers in a triangular shape as a whole, the number of vertical bars 1 is six, and the number of support tiles 6 is twelve. In the conventional example, eight vertical bars 1 and 16 support tiles 6 are required, so that two vertical bars 1 and four support tiles 6 can be reduced. In addition, when the functional panels 4 are installed in a staggered arrangement as a whole in a trapezoidal shape as shown in FIG. 2, the number of vertical bars 1 is 7, and the number of support tiles 6 is 15. In the conventional example of FIG. Since 14 vertical bars 1 and 28 support tiles 6 are required, seven vertical bars 1 and 13 support tiles 6 can be reduced.

  In the embodiment of FIGS. 1 and 2, the functional panels 4 are arranged in a staggered manner at all stages where the functional panels 4 are arranged. However, the present invention is limited to such an arrangement. Instead, there may be a step where the functional panels 4 are aligned vertically and do not have a staggered arrangement in some adjacent steps.
