  Referring to FIG. 1, a gantry 10 according to an embodiment of the present invention is attached to a roof 110 of a building 100, and a plurality of energy conversion devices 200 are further attached thereon. Here, the roof 110 of the building 100 has at least a ridge top 120 and two roof surfaces 130 sandwiching the ridge top 120, such as a gable roof or a dormitory roof. Further, an eaves plate 150 for fixing a rain gutter (omitted in FIG. 1) is provided at the eaves of the building 100. In addition, the energy conversion apparatus 200 by this Embodiment is a photovoltaic power generation panel or a solar cell module.

  As shown in FIGS. 1 and 2, the gantry 10 according to the present embodiment is formed by connecting lattice-like structures 30 respectively provided on a roof surface 130 by a ridge top metal fitting 20. Each lattice-like structure 30 is formed by fixing a plurality of vertical members 50 and a plurality of transverse members 60 in a lattice shape. In the illustrated lattice-like structure 30, the horizontal member 60 is located on the roof surface 130 side. However, depending on the material of the roof, the lattice-like structure 30 so that the vertical member 50 is located on the roof surface 130 side. It is good also as comprising.

  As best shown in FIG. 1, the ridge top bracket 20 has a shape that allows the lattice structures 30 to be connected to each other in a state of being separated from the ridge top 120 when the gantry 10 is arranged on the roof 110. It has a certain shape. The predetermined shape of the ridge top metal fitting 20 is determined by sufficiently measuring the size of each part of the ridge top 120 of the roof 110 before construction. Since the ridge top metal fitting 20 has a predetermined shape, it is possible to avoid applying a load to the ridge top 120 of the roof 110 in a state where the gantry 10 is disposed on the roof 110. The ridge top metal fitting 20 according to the present embodiment is formed by bending as shown in FIG. 3, but may be configured by welding a metal piece or the like. In addition, as shown in FIG. 3, the ridge-top metal fitting 20 is formed with two sets (two in total) of holes 22 for fixing the vertical member 50 in two places.

  The vertical member 50 and the horizontal member 60 according to the present embodiment are obtained by processing a raceway 70 as shown in FIGS. 4 and 5. This raceway 70 is made of a galvanized steel plate, and even when used on the roof 110, corrosion or the like is unlikely to occur. Further, since the raceway 70 is light as expected from the structure shown in FIG. 5, the lattice-like structure 30 configured using the raceway 70 is also light, and thus the gantry 10 is mounted on the roof 110. There is an advantage that the burden on the roof 110 in the state can be reduced. Furthermore, if the vertical member 50 and the horizontal member 60 are manufactured by processing an inexpensive raceway 70, the total cost of the gantry 10 can be reduced.

  With reference to FIG. 2, when assembling the gantry 10 on the roof 110, first, a plurality of sub-structures 40 are formed by connecting the vertical members 50 with the ridge-top metal fittings 20. Next, by connecting the plurality of sub-structures 40 using the lateral member 60, the two lattice-like structures 30 are formed. When assembled in this procedure, it is not necessary to mount the completed platform 10 on the roof 110 using equipment such as a crane, and the platform 10 is placed on the roof 110 by working on the roof 110 with a small number of people. Can be assembled.

  As shown in FIG. 6, the connection between the vertical member 50 and the horizontal member 60 uses one bolt 72 and two nuts (a first nut 74 and a second nut 76). In the present embodiment, first holes 62 are respectively formed at a plurality of joint portions of the transverse member 60 located on the roof surface 130 side with the longitudinal member 50, and bolts 72 are respectively formed in the first holes 62. It is fixed using a first nut 74. As a result, the bolt 72 protrudes from the lateral member 60. The bolt 72 and the first nut 74 are preferably attached to the cross member 60 before the cross member 60 is raised on the roof 110 in order to minimize the work on the roof 110. On the other hand, the 2nd hole 52 is formed in the some joining location with the horizontal member 60 in the vertical member 50, respectively. When combining these, by inserting the bolt 72 protruding and fixed to the horizontal member 60 into the second hole 52 of the vertical member 50, the bolt 72 is fixed by the second nut 76 different from the first nut 74. The vertical member 50 and the horizontal member 60 are connected to form the lattice structure 30. In this embodiment, since the horizontal member 60 is located on the roof surface 130 side, the bolt 72 is fixed to the horizontal member 60 in advance by the first nut 74, but the vertical member 50 is on the roof surface 130 side. 1, the first hole is formed in the vertical member 50, and the bolt 72 is fixed to the vertical member side in advance by the first nut 74.

  Since the gantry 10 assembled on the roof 110 in this manner is mounted on the two roof surfaces 130 so as to straddle the ridge top portion 120, the gantry 10 is pressed onto the roof 110 by its own weight. That is, the gantry 10 is balanced on the roof 110 by its own weight. Therefore, it is not necessary to perform drilling or the like on the roof 110 when the gantry 10 is mounted on the roof 110. However, when the energy conversion device 200 mounted on the gantry 10 receives wind force, the gantry 10 may be misaligned. In order to prevent such displacement of the gantry 10 due to the wind, the gantry 10 is fixed to the building 100 using the metal fittings 80 and the wires 90 in the present embodiment. Specifically, the fixing position of the metal fitting 80 is the eaves plate 150 provided at the eaves of the building 100. The metal fitting 80 fixed to the eaves plate 150 and the gantry 10 are connected and fixed by a wire 90.

  As shown in FIGS. 1, 7, and 8, in this embodiment, the metal fitting 80 is an L-shaped metal fitting, and has an L-shaped main portion 82 including a first portion 83 and a second portion 84. ing. A hole 86 for connecting the wire 90 is provided at one end of the first portion 83 (that is, one end of the main portion 82). A fixed portion 87 that is fixed to the eave plate 150 is provided at one end of the second portion 84 (that is, the other end of the main portion 82). In the present embodiment, the surface where the main portion 82 exists and the surface where the fixed portion 87 exists are orthogonal to each other.

  When the gantry 10 and the metal fitting 80 are connected by the wire 90, they may be connected only by the wire 90 as on the roof surface 130 on the south side in FIG. 2, or on the roof surface 130 on the north side in FIG. It is good also as connecting with the wire 90 so that the turnbuckle 92 may be included in.

  After the gantry 10 is mounted and fixed on the roof 110 in this way, the energy conversion device 200 is mounted on the gantry 10. Specifically, as shown in FIG. 9, a mim fitting 210 is previously attached to the energy conversion device 200 using bolts 220, and a lattice structure is formed on the roof 110 using the mim fitting 210. The energy conversion device 200 is fixed to 30, thereby installing the energy conversion device 200 on the roof 110.

  In the embodiment described above, the metal fitting 80 for fixing the gantry 10 to the eaves plate 150 is an L-shaped metal fitting, but the present invention is not limited to this. Specifically, as shown in FIGS. 10 and 11, the metal fitting 80a includes an L-shaped main portion 82a composed of a first portion 83a and a second portion 84a, and a fixed portion 87a fixed to the eaves plate 150. And a reinforcing portion 88a. A hole 86a for connecting the wire 90 is formed at one end of the first portion 83a (that is, one end of the main portion 82). The fixed portion 87a is provided at one end of the second portion 84a (that is, the other end of the main portion 82). Also in the case of the metal fitting 80a according to this modification, the surface where the main portion 82a exists and the surface where the fixed portion 87a exists are orthogonal to each other. The reinforcing portion 88a extends from the main portion 82a so that the reinforcing portion 88a and the main portion 82a form an inverted F shape (a shape like a katakana bee). The illustrated reinforcing portion 88a is a plate-like portion, and the surface where the main portion 82a exists and the surface where the reinforcing portion 88a exists intersect. More specifically, the reinforcing portion 88a extends slightly obliquely from the first portion 83a of the main portion 82a toward the fixed portion 87a.

  As shown in FIG. 11, the fixed portion 87 a of the metal fitting 80 a is fixed to the eaves plate 150 on the lower side of the rain gutter 140, and the reinforcing portion 88 a is in contact with the eave plate 150 beyond the rain gutter 140. When the metal fitting 80a is used, even when the wire 90 is pulled upward, the reinforcing portion 88a abuts against the eaves plate 150 and the load applied to the fixed portion 87a can be reduced.

  Furthermore, the metal fitting 80 may be replaced with a metal fitting (dendex screw) 80b as shown in FIG.

  Referring to FIGS. 13 and 14, there is shown a modified example using a gantry 10 a having a ridge top metal part 20 a having a shape different from the ridge top metal part 20 in accordance with the shape of the ridge top part 120 a of the roof 110 a. As shown in FIGS. 15 and 16, the ridge top bracket 20 a extends in the direction intersecting the plate at the tip of a Katakana U-shaped (square C-shaped) plate (a portion straddling the ridge top 120 a). A plate is welded, and a screw fastening hole 22a is formed in a portion connected to the vertical member 50.

  In the example shown in FIG. 13, two means of a metal fitting 80 and a metal fitting (dendex screw) 80 b are used as a fixing means for the gantry 10 mounted on the roof 110. In this way, the metal fittings 80 and 80b may be mixed, or the metal fitting 80a may be further mixed.

  The ridge top bracket may have any shape as long as it does not contact the ridge top. For example, when the ridge top does not protrude, the ridge top bracket 20b may have a shape as shown in FIGS. A plurality of holes 22b are also formed in the illustrated ridge top metal fitting 20b, and the vertical members 50 can be connected with bolts using them.

  Further, as shown in FIG. 19, the energy conversion device 200 is attached and fixed to the lattice structure 30 on the south side roof surface 130, while the three-dimensional support 35 is assembled on the north side roof surface 130. It is good also as attaching to the lattice-shaped structure 30, and attaching and fixing the energy converter 200 to the solid support body 35. FIG. If comprised in this way, since it can obtain equivalent to expanding the roof surface 130 of the south side, the space on the roof 110 can be utilized effectively.

  As described above, the present invention has been described with various specific examples. However, the present invention is not limited to this, and various modifications can be made. For example, as long as the lattice structure formed by connecting the vertical member and the horizontal member is connected by the ridge top metal fitting, the specific configuration of the gantry is not limited. For example, a structure like the gantry 10 shown in FIG. 2 or 20 may be used, or a structure like the gantry 10d shown in FIG. 21 may be used. Furthermore, the mounting direction of the energy conversion device 200 on the gantry 10 or 10d may be vertical as shown in FIG. 20, or may be horizontal as shown in FIG.
