Description

  The present invention relates to a construction jig used for installing a solar cell module on a roof of a building.

  In the construction of installing a solar cell module on the roof of a building, a plurality of mounting holes are made using a drilling electric tool in a roofing material such as a decorative slate that is wound on the roof. Thereafter, the fixture is installed on the roof material by fixing the fixing screw to each of the attachment holes, and the solar cell module is supported by the fixture. In such an installation method, when a plurality of mounting holes are made in the roof material, a construction jig for defining the positional relationship between the mounting holes is used (for example, see Patent Document 1).

  In the installation method of the solar cell module described above, it is essential to open the mounting holes at predetermined intervals in the roof material, and if the mounting holes are in the wrong position, the mounting tool cannot be installed, Leakage may occur. Therefore, it is required to open the attachment holes at predetermined positions with respect to the roof material. However, although the conventional construction jig disclosed in Patent Document 1 defines the positional relationship between the mounting holes, it is difficult to position the location where the mounting holes are formed with respect to the roofing material.

  Further, when a plurality of solar cell modules are installed so as to be arranged on one surface of the roof, an interval defined by the installation method must be ensured between adjacent solar cell modules. If this interval is shorter than the specified interval, adjacent solar cell modules may collide with each other and be damaged when a metal frame member such as aluminum of the solar cell module expands due to a temperature change.

  Moreover, if the interval is not constant, not only the impression is given and the aesthetic appearance is impaired, but the fixing range defined for each solar cell module is difficult to fix to the roof with a fixture, and the solar cell module itself Strength is not secured. Then, although the space | interval of adjacent solar cell modules is measured with a tape measure or a ruler, it is set as the predetermined space | interval, but it takes time and effort as the number of solar cell modules to be installed increases, and the installation work is prolonged accordingly.

  This invention is made | formed in view of such a point, The objective place positions the formation location of the attachment hole with respect to a roof material, and ensures a predetermined space | interval between adjacent solar cell modules. It is to provide a construction jig.

  The present invention is a work for installing a plurality of solar cell modules next to each other by using a fixture that is installed by fixing a fastener to the mounting hole by making a mounting hole in a roof material that is wound on the roof of a building A flat plate portion having a through hole into which a drilling shaft of a tool used for drilling the mounting hole is inserted, and the thickness of the flat plate portion with respect to the main surface of the flat plate portion A first protrusion protruding to one side in the direction, and the first protrusion is located at a distance from the through hole of the flat plate portion in the first direction, and the flat plate portion is By contacting the eaves side end surface of the roofing material in a state of being directed to the surface of the roofing material, the flat plate portion is positioned in the first direction with respect to the roofing material on the side end surface of the roofing material.

Embodiment 1
In this Embodiment 1, the case where a solar cell module array is installed in the roof of a general house is mentioned as an example about the construction jig which concerns on this invention, and is demonstrated.

  First, an example of the solar cell module array 10 installed using the construction jig 50 according to the first embodiment will be described with reference to FIGS. 1 and 2. FIG. 1 is a top view (plan view) of a roof 101 of a house 100 in which a solar cell module array 10 is installed. FIG. 2 is a partial perspective view of the solar cell module array 10 installed on the roof 101. In FIG. 2, for the sake of convenience, a part of the solar cell module 11 is shown through.

  As shown in FIG. 1, the solar cell module array 10 is installed on one side of a gable roof 101 of a house 100, and a plurality of solar cell modules 11 are arranged in a matrix (21 solar cells in the example shown in FIG. 1). Modules 11 are arranged in 3 rows and 7 columns. The roof 101 has a roof base in which a roofing material or the like is stretched on a base plate supported by a rafter (not shown), and a plurality of decorative slate 102 as a roof material overlaps a part of the roof base. Has a strung structure. Of the makeup slate 102 adjacent in the gradient direction of the roof 101, the lower part (end part on the eaves side) of the makeup slate 102 located on the upper side (ridge side) is the upper part of the makeup slate 102 located on the lower side (eave side) ( It is arranged to cover the ridge side end) and exposed to the outside.

  The solar cell module 11 has a structure in which a metal frame member 13 such as aluminum is mounted on the outer periphery of the solar cell panel 12 (see FIGS. 7 and 9). The solar battery panel 12 is, for example, a solar battery cell that is a photoelectric conversion element using a sealing material between a glass substrate that forms a light receiving surface and a resin back surface protective member that is the opposite surface to the light receiving surface. Is a horizontally-long rectangular flat plate. Although not shown in the figure, a terminal box is fixed to the back surface of the solar cell panel 12, and two cables extend outward from the terminal box. One of the two cables is a positive cable, and the other is a negative cable.

  The solar cell modules 11 are connected in series using the two cables to form one system. And the electric power generated by each solar cell module 11 is drawn indoors using a lead-in cable for every system. Here, as shown in FIG. 2, the solar cell module 11 uses a fixture 20 installed by opening a mounting hole 103 in the decorative slate 102 and fixing a fixing screw 30 as a fastener to the mounting hole 103. Installed.

  The fixture 20 is located within a predetermined distance range from both ends in the width direction (longitudinal direction) of each solar cell module 11, and 2 on the long side on the ridge side and the long side on the eaves side of each solar cell module 11. A plurality of pieces are installed on the roof 101 so as to be supported at a total of four places. The fixture 20 includes a base member 21 disposed on the roof 101, a connection member 22 that engages with the base member 21 and moves along the base member 21, and a presser member 23 that is attached to the connection member 22. including. The base member 21 and the connection member 22 are made of, for example, stainless steel subjected to hot dip aluminum plating. The pressing member 23 is formed, for example, by extruding aluminum.

  The base member 21 is a rail-shaped member whose cross-sectional shape is a so-called reverse hat shape. The connection member 22 includes a top plate portion 24 and side wall portions 25 provided at both ends of the top plate portion 24. The side wall 25 is formed with an engaging groove 27 that engages with a mounting piece 26 corresponding to the flange of the inverted hat-shaped base member 21. The connecting member 22 is assembled to the base member 21 by sliding the mounting piece 26 from one end side in the longitudinal direction of the base member 21 while inserting the mounting piece 26 into the engaging groove 27. The holding member 23 is a rail-shaped member whose cross-sectional shape is a reverse hat shape, and is fastened to the top plate portion 24 of the connecting member 22 by a fastener 28 including a connecting bolt and a nut. The connecting member 22 is positioned on the base member 21 by positioning bolts 29.

  The fixture 20 is screwed to the roof 101 at a plurality of locations (three locations aligned in a straight line in the example shown in FIG. 2) by fixing screws 30 inserted into the mounting holes 103 formed in the decorative slate 102. The base member 21 is installed on the decorative slate 102 in a posture in which the longitudinal direction of the base member 21 is aligned with the gradient direction of the roof 101. The positions of the mounting holes 103 with respect to the cosmetic slate 102 are determined, and it is necessary to form the mounting holes 20 at predetermined intervals in order to securely install the mounting tool 20 and prevent water leakage. The construction jig 50 according to the first embodiment is used for the work of drilling the attachment hole 103 at a predetermined position with respect to the decorative slate 102.

  In the fixture 20, the position of the connection member 22 relative to the base member 21 is changed according to the position relative to the solar cell module array 10. For example, in the case of the solar module array 10 as shown in FIG. 2, the connection member 22 is positioned closer to the eave side end of the base member 21 in the most eaves-side fixture 20, The connecting member 22 is positioned closer to the ridge side end of the base member 21. Further, in the intermediate fixture 20, the connection member 22 is positioned around the middle of the base member 21. And the eaves side cover 40 which hides the said fixture 20 with the eaves side edge part of the solar cell module 11 for every row | line | column of the solar cell module 11 is attached to the fixture 20 of the eaves side.

  The solar cell module 11 has its lower end edge pressed by the mounting piece 26 of the base member 21 by the pressing members 23 of the two fixtures 20 arranged on the lower side (eave side) on the lower side (eave side). The upper edge is pressed onto the mounting piece 26 of the base member 21 by the pressing members 23 of the two fixtures 20 arranged on the upper side (ridge side) on the left and right (girder direction). The solar cell module 11 is held by these four fixtures 20. Thus, the solar cell module 11 is installed on the roof 101 with each long side portion fixed by the two fixtures 20.

  The interval between the solar cell modules 11 adjacent in the row direction corresponding to the eaves ridge direction is defined by the width of the pressing member 23 of the intermediate fixture 20. On the other hand, since the interval D between the solar cell modules 11 adjacent to each other in the row direction corresponding to the digit direction is not determined by the fixture 20, damage due to expansion of the frame member 13 of the solar cell module 11 is prevented and In order to improve the appearance of the battery module array 10, it is necessary to align the solar cell module 11 with a predetermined width when installing the solar cell module 11.

  The distance D varies between a relatively narrow first distance d1 (for example, 26 mm) and a relatively wide second distance d2 (for example, 41 mm) depending on the size of the solar cell module 11 to be installed and the structure of the roof base. You may be asked to do that. The construction jig 50 to be described later is also used for an operation of installing the solar cell module 11 while ensuring a predetermined distance D between the adjacent solar cell modules 11.

  Next, the construction jig 50 according to the first embodiment will be described with reference to FIGS. 3 and 4. FIG. 3 is a perspective view of the construction jig 50. FIG. 4 is a side view of the construction jig 50 as viewed from the direction A.

The flat plate portion 51 has a first main surface 58 and a second main surface 59 that face each other in the jig thickness direction. The first main surface 58 is one main surface of the flat plate portion 51 (the surface having the largest area or the second largest surface). The second main surface 59 is a main surface facing the first main surface 58 of the flat plate portion 51. That is, the first main surface 58 and the second main surface 59 are two surfaces in a relationship in which one of them can be interpreted as “front surface” and the other as “back surface”.

  The flat plate portion 51 is formed by a relatively wide portion 54 corresponding to one side in the jig length direction and a relatively narrow portion 55 corresponding to the other side in the length direction. A plurality of (three in the example shown in FIG. 3) through-holes 56 are formed in the jig length direction in a region from the central portion that is the boundary between the wide portion 54 and the narrow portion 55 to the wide portion 54. Formed in a row at intervals. The through hole 56 is sized so that a drill bit 201 (drilling shaft) of the electric power tool 200 used for drilling the attachment hole 103 into the decorative slate 102 can be inserted. The member inserted into the through hole 56 is not limited to a rotating tool such as the drill bit 201, but may be any tool that forms the attachment hole 103 suitable for inserting and fixing the fixing screw 30. The type is irrelevant.

  Further, notches 57 used for alignment in the girder direction with the decorative slate 102 are respectively formed at both ends of the flat plate portion 51 in the jig length direction. The notch 57 has a triangular shape in which a corner is directed inward of the flat plate portion 51 at a central portion in the jig width direction of each end edge of the flat plate portion 51 in the direction in which the wide portion 54 and the narrow portion 55 are separated from each other. And located on a straight line in the jig length direction with the plurality of through holes 56 interposed therebetween.

That is, two first protrusions 52 and two second protrusions 53 are provided at intervals in the jig width direction. The first protrusion 52 and the second protrusion 53 are rectangular plate pieces bent and raised opposite to each other in the jig thickness direction, and are spaced apart from each other in the jig length direction. And have a function as a spacer for determining an interval between adjacent solar cell modules 11.

  The first protrusions 52 are located on both sides of the edge portion opposite to the wide portion 54 in the jig length direction of the narrow portion 55, and the first protrusions 52 are first with respect to the first main surface 58 of the flat plate portion 51. 1 is bent and raised to the side facing the main surface 58, and is formed at a distance from the through hole 56 in the jig length direction. The first protrusion 52 extends along the plate surface in the jig length direction, and is inclined with respect to the jig width direction and the jig thickness direction from the flat plate portion 51 toward the outside in the jig width direction. It is formed in a posture extending in the direction. That is, when the construction jig 50 is viewed from one side in the jig length direction, the pair of first protrusions 52 have a depression angle on the first main surface 58 side while being separated from the flat plate part 51. Extends into a square shape.

  The height h1 of the first protrusion 52 relative to the first main surface 58 of the flat plate portion 51 is equal to or less than the thickness of the decorative slate 102. This is to prevent the first protrusions 52 from supporting and lifting on the lower row of the cosmetic slate 102 when the construction jig 50 is used to drill the attachment hole 103 in the cosmetic slate 102. Specifically, the height h1 of the first protrusion 52 is set to 1 mm or more and 5 mm or less. The length of the first protrusion 52 in the jig length direction is a dimension that determines the interval D between the adjacent solar cell modules 11, and is set to a size corresponding to the first interval d1, for example, 26 mm. The

It is bent up to the side. The second protrusion 53 extends along the plate surface in the jig length direction, and is inclined with respect to the jig width direction and the jig thickness direction from the flat plate portion 51 toward the outside in the jig width direction. It is formed in a posture extending in the direction. That is, when the construction jig 50 is viewed from one side in the jig length direction, the pair of second protrusions 53 has a depression angle on the second main surface 59 side while being separated from the flat plate part 51. Extends into a square shape.

  The height h <b> 2 of the second protrusion 53 with respect to the second main surface 59 of the flat plate portion 51 is also equal to or less than the thickness of the decorative slate 102. Specifically, the height of the second protrusion 53 is also set to 1 mm or more and 5 mm or less. The length of the second protrusion 53 in the jig length direction is a dimension that determines the interval D between the adjacent solar cell modules 11, and is set to a size corresponding to the second interval d2, for example, 41 mm. The

  The construction jig 50 described above is configured so that the first protrusion 52 is brought into contact with the eaves side end surface of the decorative slate 102 in a state where the flat plate portion 51 is directed to the decorative slate 102, so The flat plate portion 51 is slid in the jig width direction (that is, the girder direction) along the eave side end surface of the decorative slate 102 while positioning the flat plate portion 51 in the jig length direction (that is, the eaves building direction). And the construction jig 50 is the spacer which ensures the 1st space | interval d1 between these solar cell modules 11 by pinching | interposing the 1st protrusion 52 between the solar cell modules 11 adjacent in a digit direction. The second protrusion 53 is sandwiched between the solar cell modules 11 adjacent to each other in the girder direction, thereby functioning as a spacer that secures the second distance d2 between the solar cell modules 11. .

Subsequently, the eaves side cover 40 is attached, the wiring operation for connecting the cables of the solar cell modules 11 is performed while the solar cell modules 11 are arranged at predetermined positions, and the solar cell modules 11 are fixed by the fixtures 20. The construction jig 50 is used for the work of drilling the attachment hole 103 in the decorative slate 102 and the work of arranging the solar cell module 11.

  In the operation of perforating the attachment hole 103 in the decorative slate 102, a flathead screwdriver is inserted under the cosmetic slate 102 perforating the attachment hole 103, the cosmetic slate 102 is floated, and the waterproof sheet 104 shown in FIG. 5 is inserted. Next, as shown in FIG. 5, the construction jig 50 is directed to the surface of the decorative slate 102 from the first main surface 58 side in a posture in which the first protrusion 52 faces the eaves side, The first protrusion 52 is brought into contact with the eaves side end face of the makeup slate 102 to position the flat plate portion 51 in the eaves ridge direction with respect to the makeup slate 102. Further, the construction jig 50 is slid in the jig width direction along the eaves side end face of the decorative slate 102 and the notch 57 is aligned with the inking line 203, so that the through-hole 56 is formed with respect to the decorative slate 102. Position in the direction. Then, by sequentially inserting a drill bit (drilling shaft) 201 to be rotationally driven into each through hole 56 of the construction jig 50 using the drilling electric tool 200, a plurality of mounting holes 103 are formed in a predetermined manner on the decorative slate 102. Leave a certain interval in the position.

  In the operation of arranging the solar cell modules 11, when the interval D between the adjacent solar cell modules 11 in the girder direction is set as the first interval d <b> 1, as shown in FIGS. 6 and 7, between the adjacent solar cell modules 11. The first protrusion 52 is sandwiched in the jig length direction and used as a spacer, thereby securing a first distance d1 between the solar cell modules 11. Further, when the interval D between the solar cell modules 11 adjacent in the digit direction is the second interval d2, as shown in FIGS. 8 and 9, the second protrusion 53 is provided between the adjacent solar cell modules 11. A second space d2 is secured between the solar cell modules 11 by sandwiching them in the jig length direction and using them as spacers. As described above, when the construction jig 50 is used, the interval D between the solar cell modules 11 adjacent in the girder direction can be aligned at two different intervals.

  According to the construction jig 50 according to the first embodiment, the first protrusions 52 are provided at intervals in the jig length direction with respect to the through holes 56 formed in the flat plate part 51. Thus, in a state where the flat plate portion 51 is directed to the surface of the decorative slate 102, the first protrusion 52 is brought into contact with the eaves side end surface of the decorative slate 102, and the through hole 56 is made to the decorative slate 102. The position, that is, the location where the mounting hole 103 is formed is positioned in the jig length direction. Furthermore, at the time of this positioning, the construction jig 50 can also be adjusted so as to be aligned with the cornering line 203 by sliding in the jig width direction. That is, if the construction jig 50 is used, the location where the attachment hole 103 is formed with respect to the decorative slate 102 can be easily and accurately positioned.

  Furthermore, the function as a spacer which determines the space | interval D of the solar cell module 11 adjacent to a 1st protrusion part 52 and the 2nd protrusion part 53 of the construction jig 50 adjacent to a digit direction is provided. Since the space D between the solar cell modules 11 to be secured is made different by the first protrusions 52 and the second protrusions 53, when the solar cell modules 11 are installed, the suns adjacent in the digit direction Even if the distance D between the battery modules 11 is not measured one by one, the first protrusion 52 or the second protrusion 53 is sandwiched between the adjacent solar cell modules 11, so that a predetermined distance is established between the solar cell modules 11. As the interval D, the first interval d1 or the second interval d2 is selectively secured. Therefore, installation work (construction) of the plurality of solar cell modules 11 can be performed efficiently.

However, the present invention is not limited thereto. For example, in addition to the first to third protrusions 52, 53, and 60, the construction jig 50 is provided in a pair in both sides of the flat plate portion 51 in the jig width direction, and is second in the jig thickness direction. A fourth protrusion that is bent and raised on the same side as the protrusion 53 of the solar cell module 11 may be further included so that the intervals D of the solar cell modules 11 adjacent to each other in the girder direction can be aligned at four different intervals. . Further, the construction jig 50 includes the first protrusion 52 and the third protrusion 60, and does not need to include the second protrusion 53.

  Moreover, in the said Embodiment 1, although the construction jig | tool 50 mentioned and demonstrated as an example the form formed by bending a metal plate-shaped member, it does not restrict to this. The construction jig 50 integrates the metal or resin parts to be the first protrusion 52 and the second protrusion 53 by bonding or welding to the metal plate member forming the flat plate portion 51. It may be formed. This is the same for the construction jig 50 of the second embodiment. That is, in the construction jig 50 according to the second embodiment, the first to third protrusions 52, 53, and 60 may be formed of separate parts from the plate-like member that is the flat plate portion 51.

  In the first embodiment, the roof 101 on which the decorative slate 102 is spread is described as an example of the roof 101 on which the solar cell module 11 is installed. However, the present invention is not limited to this. The decorative slate 102 is only an example of a roofing material, and any other roofing material can be used as long as the mounting hole 103 is drilled by a tool and the mounting tool 20 is installed by fixing the fastening tool such as the fixing screw 30 to the mounting hole 103. Solar cell modules are roofs that are covered with any type of roofing material, such as natural slate, which is a slate roofing material, cement-based roofing materials such as press-cement tiles and concrete tiles, and viscosity-type roofing materials such as Japanese tiles. 11 may be set as installation targets.
