  The roof structure according to the present embodiment is a roof structure in which flat tiles 4 and support tiles 2 are overlaid on a roof base 1 and a roof addition facility 5 is further installed. A support member 3 is installed on the support tile 2. The support member 3 is configured to support the roof addition facility 5. The flat roof tile 4 includes a first flat roof tile 41 disposed on the eaves side with respect to the support roof tile 2 and a second flat roof tile 42 disposed on the eaves side with respect to the first flat roof tile 41. The eaves side portion of the support tile 2 and the ridge side portion of the second flat tile 42 are overlapped via the first flat tile 41. The support member 3 is installed in a portion 20 (hereinafter referred to as an overlapping portion 20) that overlaps the ridge side portion of the second flat roof tile 42 in the eaves side portion of the support tile 2.

  Since the roof structure according to the present embodiment has such a configuration, the load of the roof addition equipment 5 is directly below the overlapping portion 20 of the support tile 2, the first flat tile 41, the second flat tile 42, and the roof base 1. Can be received sequentially. Furthermore, the gap between the second flat tile 42 and the roof base 1 is reduced immediately below the overlapping portion 20. For this reason, the flat roof tile 4 which receives the load of the roof addition equipment 5 becomes difficult to bend, and the damage of the flat roof tile 4 is suppressed. In the present embodiment, all the loads applied from the support member 3 to the support tile 2 are applied to the overlapping portion 20, but the present invention is not limited to this. A part of the load applied from the support member 3 to the support tile 2 may be applied to the overlapping portion 20 to such an extent that the first flat plate tile 41 is not cracked. For example, the eaves side portion of the support member 3 may be fixed on the surface of the overlapping portion 20, and the ridge side portion may be fixed to a region other than the overlapping portion 20 in the support tile 2.

  The roof structure according to this embodiment will be described in more detail.

  The roof addition equipment 5 in the roof structure of the present embodiment is not particularly limited as long as it is installed on the roof. The roof addition facility 5 may be a photovoltaic power generation panel, a water heater, a signboard, or the like, or may be a member for installing these facilities. In this embodiment, a frame for installing a photovoltaic power generation panel is installed as the roof addition equipment 5.

  First, the installation structure of the flat roof tile 4 in this embodiment is demonstrated with reference to FIG.

  The flat roof tile 4 in this embodiment is a slate roof tile having a rectangular shape in plan view. The flat roof tiles 4 are all formed in the same shape. A plurality of flat tiles 4 are provided on the roof base 1 in the direction of the eaves of the roof. Further, a plurality of flat tiles 4 are provided on the roof base 1 in a direction orthogonal to the eaves direction of the roof. The flat roof tile 4 may be installed directly on the roof base 1 or may be installed on a roof sheet 1 on which a waterproof sheet or the like is arranged.

  In the present embodiment, a plurality of convex portions 40 having a hexagonal shape in plan view are provided on the non-exposed portion of the flat roof tile 4. These convex portions are arranged in a turtle shell pattern. The non-exposed portion is a portion on the ridge side of the upper surface of the flat roof tile 4 and is a portion that overlaps with the other flat roof tile 4 when the flat roof tile 4 is installed on the roof. For this reason, even if water such as rainwater enters the unexposed portion of the flat roof tile 4, water flows through the gaps between the convex portions, so that it is difficult for the water to reach the ridge side portion of the flat roof tile 4, Water that has entered between the flat roof tiles 4 is easily discharged. In the present embodiment, the plurality of convex portions 40 having a hexagonal shape in plan view are provided. However, the present invention is not limited to this, and there is a gap that allows water such as rainwater to flow between the overlapping flat roof tiles 4. What is necessary is just to form, and uneven | corrugated shapes, such as a grain shape and a stone-splitting shape, and the unevenness | corrugation by sanding painting etc. may be sufficient.

  In addition, in this specification, the eave side is an oblique lower side along the slope of the roof, the ridge side is an oblique upper side along the slope of the roof, and the eaves direction is It is the direction along the slope of the roof.

  The flat roof tile 4 of this embodiment is provided as follows, for example.

  On the ridge side portion of the flat roof tile 4 (for example, the second flat roof tile 42 shown in FIGS. 1 and 4), another flat roof tile 4 (for example, shown in FIGS. The first flat roof tile 41) is overlapped. Of the two flat roof tiles 4 adjacent to each other in the eave building direction, the arrangement position of the flat roof tile 4 on the building side in the direction orthogonal to the eave building direction is the eave building direction with respect to the arrangement position of the flat roof tile 4 on the eave side. Is shifted by a half of the working width in the direction orthogonal to the eaves direction of the flat roof tile 4 in the direction orthogonal to In addition to the ½ shift as in the present embodiment, an arbitrary shift width such as ３ can be selected. The flat roof tile 4 is not limited, but is fixed on the roof base 1 with, for example, nails or screws.

  The support tile 2 of this embodiment is installed as follows, for example.

  As shown in FIG. 2, the support tile 2 is a tile having a rectangular shape in plan view and having substantially the same dimensions as the flat tile 4. The support tile 2 is made of a material having a strength that can support the roof addition equipment 5. Although the support tile 2 is not restrictive, it is made, for example, by casting aluminum. The support roof 2 preferably has an appearance close to that of the flat roof tile 4. In this case, in the roof structure in which the flat roof tile 4 and the support roof 2 are installed, the support roof 2 and the flat roof tile 4 can be familiarized in appearance. Similar to the flat roof tile 4, a plurality of convex portions 22 having a hexagonal shape in plan view are provided on the non-exposed portion of the support roof 2. In this case, it is difficult for water such as rainwater that has entered the exposed portion of the support tile 2 to reach the ridge side of the support tile 2, and the water that has entered between the support tile 2 and the flat roof tile 4 is discharged. It's easy to do. The support tile 2 is arranged in place of the flat tile 4 at a specific position on the roof.

  Here, as shown in FIG. 1, the eaves side portion of the first flat roof tile 41 overlaps the ridge side portion of the second flat roof tile 42. Further, the overlapping portion 20 of the support tile 2 is overlaid on the ridge side portion of the first flat roof tile 41. Furthermore, the eaves side portion of the third flat roof tile 43 overlaps the ridge side portion of the support tile 2.

  In this embodiment, it is preferable that the dimension of the eaves-ridge direction of the overlapping part 20 of the support tile 2 is 50 mm or more. In this case, the waterproofness of the roof is ensured.

  A support member 3 is installed on the support tile 2. The support member 3 is installed on the overlapping portion 20 of the support tile 2. The support member 3 is installed on an arbitrary place on the support tile 2 in a direction orthogonal to the eaves-ridge direction.

  The support member 3 is configured to support the roof addition facility 5. As shown in FIG. 3, the support member 3 of this embodiment includes a support portion 31, a leg portion 32, and a fixed piece 33. A hole 30 is provided in the support portion 31.

The fixing piece 33 protrudes perpendicularly to the leg portion 32 from the lower end of the leg portion 32. The fixed piece 33 is fixed on the support tile 2 by driving rivets or screws into the fixed piece 33 in a state of being arranged on the support tile 2. The support member 3 having the above configuration is not limited, but is manufactured by, for example, bending a metal plate such as a steel plate.

  The roof addition equipment 5 is supported by the support member 3 provided on the support tile 2 as described above. The roof addition facility 5 of this embodiment is supported not only by the support member 3 but also by the auxiliary support member 6. Specifically, as shown in FIGS. 6A and 6B, the roof addition equipment 5 of the present embodiment is supported by the four support members 3 and the four auxiliary support members 6. ing.

  As shown in FIG. 5, the auxiliary support member 6 includes an auxiliary support 61 and a pedestal 62. The auxiliary support 61 is configured to support the roof addition equipment 5. As shown in FIG. 5, the auxiliary support tool 61 of the present embodiment includes a support portion 611, a leg portion 612, and a fixed piece 613.

  A hole 610 is provided in the support portion 611. A screw or the like is inserted into the hole 610, and the roof addition facility 5 is fixed by driving this screw or the like into the roof addition facility 5. The leg portion 612 protrudes downward from each of the two end edges of the support portion 611. The fixed piece 613 protrudes perpendicularly to the leg portion 612 from the lower end of the leg portion 612. The fixed piece 613 is fixed on the pedestal 62 by rivets and screws being driven into the fixed piece 613 in a state of being arranged on the pedestal 62. The auxiliary support 61 having the above-described configuration is not limited, but is manufactured, for example, by bending a metal plate such as a copper plate.

  The pedestal 62 is a plate-like member having a rectangular shape in plan view. The pedestal 62 has an area where the auxiliary support 61 can be installed. The planar view area of the pedestal 62 is narrower than the area of the exposed portion of the flat roof tile 4. Although the base 62 is not restrictive, it is formed from, for example, a metal plate, a resin plate, a ceramic plate, or the like. The auxiliary support 61 of the present embodiment is fixed to the pedestal 62 with the fixing piece 613, but is not limited thereto, and the auxiliary support 61 and the pedestal 62 may be an integral member.

  The auxiliary support member 6 is installed on the auxiliary support flat roof tile 45. The auxiliary support flat roof tile 45 is a flat roof tile 4 on which the auxiliary support member 6 is installed.

  In the present embodiment, when the auxiliary support member 6 is installed on the auxiliary support flat roof tile 45, the elastic material 7 is provided between the auxiliary support flat roof tile 45 and the auxiliary support member 6. In the present embodiment, the elastic material 7 is interposed between the pedestal 62 and the auxiliary support flat roof tile 45. The elastic material 7 is a member having elasticity. The elastic material 7 is not limited, but can include, for example, one or more materials selected from the group consisting of butyl tape, silicone rubber, and ethylene propylene rubber.

  Since the roof structure of the present embodiment has the above-described configuration, the following effects can be obtained.

  Since the roof addition facility 5 is supported by the support member 3 and the auxiliary support member 6, the load of the roof addition facility 5 can be distributed to the support member 3 and the auxiliary support member 6.

  In particular, a load applied to the support tile 2 can be sequentially received by the first flat plate tile 41, the second flat plate tile 42, and the roof base 1 immediately below the overlapping portion 20 of the support tile 2. Further, immediately below the overlapping portion 20, the gap between the second flat tile 42 and the roof base 1 is small. For this reason, the flat roof tile 4 which receives the load of the roof addition equipment 5 becomes difficult to bend, and the damage of the flat roof tile 4 is suppressed.

  In particular, the load applied to the auxiliary support flat roof tile 45 is limited by the elastic force of the elastic member 7 provided between the auxiliary support flat roof tile 45 and the pedestal 62. For this reason, even if it is not formed from materials with high intensity | strength, such as a metal, it is suppressed that the flat roof tile 45 for auxiliary | assistant support is damaged.

  Moreover, in the roof structure of this embodiment, since the roof addition equipment 5 is supported not only by the support member 3 but also by the auxiliary support member 6, the number of support members 3 necessary to support the roof addition equipment 5 is reduced. I can do it. For this reason, the number of the supporting tiles 2 can be reduced.

  In the roof structure of the present embodiment, the support tile 2 has the same shape as the flat tile 4, but is not limited thereto. The support roof 2 may be, for example, a support roof shorter than the flat roof tile 4 (hereinafter referred to as a short support roof 21). The short support tile 21 of the present embodiment is arranged together with the adjustment tile 44.

  As shown in FIG. 7, the short support tile 21 of the present embodiment is a tile whose working width in the direction orthogonal to the eave building direction is 1/3 of the working width in the direction orthogonal to the eave building direction of the flat roof tile 4. is there. The working width of the short support tile 21 in the direction orthogonal to the eaves direction is not limited to this, and if the support member 3 can be installed, for example, the work in the direction orthogonal to the eaves direction of the flat roof tile 4 It may be 1/2 of the width or 2/3. The working width of the short support tile 21 in the eave building direction is the same as the working width of the flat roof tile 4 in the eave building direction. The short support tile 21 of this embodiment is formed by casting aluminum, for example, like the support tile 2. Similar to the support tile 2, a plurality of convex portions 22 having a hexagonal shape in plan view are provided on the non-exposed portion of the short support tile 21. The convex portions 22 are arranged in a turtle shell pattern. In this case, it is difficult for water such as rainwater that has entered the exposed portion of the short support tile 21 to reach the ridge side portion of the short support tile 21, and it is easy to discharge the intruded water. In the overlapping portion 20 of the short support tiles 21, the support member 3 is installed at an arbitrary portion in a direction orthogonal to the eaves-ridge direction.

  The adjustment tile 44 of the present embodiment is made by cutting the flat roof tile 4 with an arbitrary width in the eaves-ridge direction. The working width of the adjustment tile 44 of this embodiment in the direction orthogonal to the eaves-ridge direction is 2/3 because of the flat roof tile 4. This is because the working width of the short support tile 21 in the direction perpendicular to the eave building direction is 1/3 of the working width of the flat roof tile 4 in the direction perpendicular to the eave building direction, as shown in FIG. . For this reason, the combined width of the short support tile 21 and the adjustment tile 44 is the same as the working width of the flat roof tile 4 in the direction orthogonal to the eaves-ridge direction.

  The short support tiles 21 and the adjustment tiles 44 are arranged side by side in a direction orthogonal to the eaves-ridge direction. As shown in FIG. 7, the short support tile 21 of the present embodiment is arranged on the left side in the direction orthogonal to the eave building direction of the adjustment tile 44, but is arranged on the right side in the direction orthogonal to the eave building direction. Also good. Similar to the support tile 2, the short support tile 21 and the adjustment tile 44 are arranged in place of the flat tile 4 at a specific position on the roof. In addition, when the short support tile 21 is arrange | positioned on the left side of the direction orthogonal to the eaves-ridge direction of the adjustment tile 44, the short support tile 21 is formed in the same shape as a part of the left side of the flat roof tile 4. FIG. When the short support tile 21 is arranged on the right side of the adjustment tile 44 in the direction orthogonal to the eaves-ridge direction, the short support tile 21 is formed in the same shape as a part of the right side of the flat roof tile 4.

  In the present embodiment, the drainer 8 is provided so as to overlap the lower surfaces of the short support tile 21 and the adjustment tile 44. The drainer 8 is provided on the lower surface of the joint 9 between the short support tile 21 and the adjustment tile 44. The eaves side end of the drainer 8 reaches the first flat roof tile 41. The drainer 8 is a plate-like member. The drainer 8 includes a drainer piece 81 and a protrusion 82. The protruding portion 82 protrudes upward from the ridge-side end portion of the draining piece 81 (see FIG. 8). The protrusion 82 contacts the ridge side end of the short support tile 21 and the ridge side end of the adjustment tile 44. The draining piece 81 includes a draining recess 83 (see FIG. 8). When water such as rainwater enters from the seam 9, it is received by the draining recess 83 and guided to the first flat roof tile 41. For this reason, it is suppressed that water invades on the roof base 1.

  The short support tiles 21 and the adjustment tiles 44 are arranged on the ridge side of the first flat roof tile 41 in the same manner as the support tiles 2 shown in FIG. Further, on the ridge side of the short support tiles 21 and the adjustment tiles 44, the third flat plate roof tiles 43 are disposed so as to overlap as with the support roof tiles 2.

  When the short support tile 21 and the adjustment tile 44 are installed in place of the support tile 2 shown in FIG. 2, the plan view area of the short support tile 21 is smaller than the support tile 2 shown in FIG. The material cost can be reduced as compared with the case where the supporting tile 2 is installed.

  Moreover, since the short support tile 21 can be arrange | positioned in either the right and left of the direction orthogonal to the eaves-ridge direction of the adjustment tile 44, the freedom degree of the installation position of the support member 3 improves, and installation of the roof addition equipment 5 is carried out. The degree of freedom of position is also improved.

  In the roof structure of the present embodiment, the first flat plate tile 41 and the second flat plate tile 42 are interposed between the eaves side portion of the support tile 2 and the roof base 1, but the present invention is not limited thereto. For example, in addition to the first flat tile 41 and the second flat tile 42, another flat tile 4 may be interposed between the overlapping portion 20 of the support tile 2 and the roof base 1.

  Moreover, although the structure of this embodiment is supported by the auxiliary support member 6 arrange | positioned between the four support members 3 and the support members 3, the roof addition equipment 5 is not restricted to this. For example, any number of support members 3 and auxiliary support members 6 may be installed in accordance with the shape and weight of the roof addition equipment 5. Of course, the roof addition equipment 5 may be supported only by the support member 3.
