Description

  The present invention relates to a structure in which a functional member such as a solar cell panel (PV panel) is installed on a roof surface.

  Conventionally, a functional member is attached to the roof surface (the upper surface of the roof). In attaching the functional member to the roof surface, a member called a support tile is used (for example, see Patent Document 1). The support tile is formed by integrally providing a support portion on the upper surface of a tile portion having a shape substantially equivalent to the roof material. Then, a part of the many roofing materials to be installed is replaced with the support tile, and the functional member is mounted on the roof surface by mounting the functional member between the support portions of the plurality of support tiles. It is arranged.

However, the above-described support tile has a shape different from that of a normal roof material, and is formed of a metal such as aluminum, and thus requires separate molding and processing. Therefore, as shown in FIG. 7 and the normal upper surface of the roof material 4 fitted with a supporting member 7 is disposed a plurality of support members 7 on the roof surface 2, spanned a function member between the plurality of support members 7 It has been proposed to dispose the functional member on the roof surface 2 by attaching to the roof surface 2.

By the way, in the roof material to which the functional member is attached in this manner, a large load may be applied from above when the functional member is covered with snow. When a load is applied to the roof material from above, as shown in FIG. 7, if a gap 30 is formed between the substantially central portion of the roof material 4 and the roof base 3, the roof material 4 is It could break and break due to buckling. Therefore, as shown in FIG. 8, a receiving material 31 is provided in the gap 30 between the substantially central portion of the roof material 4 and the roof base 3. The receiving material 31 is installed on the roof base 3 below the substantially central portion of the roofing material 4, and the upper surface of the receiving material 31 is in contact with the lower surface of the roofing material 4. The receiving material 31 is made of wood such as plywood. And the roofing material 4 is supported by the receiving material 31, and it becomes difficult to produce breakage, such as a crack, even if a big load is applied.

However, in the above-described conventional example, the upper surface of the receiving material 31 is processed to match the shape of the lower surface of the roofing material 4 so that the upper surface of the receiving material 31 is brought into contact with the lower surface of the roofing material 4 as wide as possible. For this reason, it is difficult to use one type of receiving material 31 in common with the roofing material 4 having different shapes. Therefore, the use of the receiving material 31 may be restricted. Further, as shown in FIGS. 8 and 9, there is a case where the tile rail 28 is used or not used for each construction site, and even when the tile rail 28 is used, the thickness of the tile rail 28 is different for each construction site. There was a change. Since the tile rail 28 is provided between one end portion (for example, the ridge side end portion) of the roof material 4 and the roof base 3, the substantially central portion of the roof material 4 and the roof according to the presence or absence and thickness of the tile rail 28. The vertical dimension of the gap 30 between the base 3 may change. Therefore, there is a problem that the thickness dimension and the installation position of the receiving material 31 have to be adjusted according to the construction site, and the construction takes time. Moreover, when adjustment of the receiving material 31 is not fully performed, the clearance gap 30 arises between the lower surface of the substantially center part of the roofing material 4, and the upper surface of the receiving material 31, and it becomes easy to produce breakage, such as a crack. There was a problem.

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

  As shown in FIG. 1, the present embodiment relates to a structure in which a functional member 1 is installed on a roof surface 2. Examples of the functional member 1 include a solar cell panel, a solar water heater, and a signboard. The roof surface 2 is formed on the upper surface of the roof material 4 when a large number of roof materials 4 are installed on the roof base 3. The roof base 3 can be formed by laying a flat field plate 6 on a roof structure material 5 such as a rafter.

  As shown in FIG. 2A, in this embodiment, a support member 7 and a load receiving material 8 are used. The support member 7 is made of a metal such as a steel material and includes a substrate 9 and a fixing portion 10. The substrate 9 has a recess 11 that is long in the front-rear direction at a substantially central portion thereof, and a convex portion 12 that is long in the front-rear direction on both sides of the recess 11. A female screw hole 13 penetrating in the thickness direction is formed in a substantially central portion of each convex portion 12 in the front-rear direction. Further, an insertion hole 14 penetrating in the thickness direction is provided at the front end portion and the rear end portion of each convex portion 12. The fixed portion 10 includes a substantially flat mounting portion 15, a front surface portion 16 substantially suspended from the front end of the placement surface 15, a rear surface portion 17 substantially suspended from the rear end of the mounting surface 15, and a front surface portion 16 and an attachment piece 18 projecting from each lower end of the rear surface portion 17. A hole 19 that penetrates in the thickness direction is provided at a substantially central portion of the mounting portion 15. A fixing screw portion 20 penetrating in the thickness direction is provided at substantially the center of each of the front surface portion 16 and the rear surface portion 17. Then, by fixing the attachment piece 18 to the bottom surface of the recess 11, the support member 7 can be formed by integrating the substrate 9 and the fixing portion 10.

  The load receiving member 8 is made of a metal such as a steel material, and is provided with a binding member 21 and a leg member 22. The binding material 21 is formed of a screw rod having an external thread on the outer periphery, like a bolt. Further, as shown in FIG. 2B, a substantially spherical fitting convex portion 23 is provided at the lower end of the binding material 21. The leg member 22 is formed in a plate shape such as a disk, and a fitting recess 24 is provided at a substantially central portion of the upper surface thereof. Then, by fitting the fitting convex portion 23 into the fitting concave portion 24, the binding material 21 and the leg material 22 can be integrated to form the load receiving member 8. Here, the fitting convex portion 23 is held in the fitting concave portion 24 so as to be able to roll (turn). Therefore, the coupling member 21 and the leg member 22 are connected to each other so that the angle can be adjusted.

And in installing the functional member 1 in the roof surface 2, it can carry out as follows. As shown in FIG. 1, first, a support member 7 and a load receiving member 8 are attached to a roof material 4 on which the functional member 1 is placed. In this case, a through hole 25 penetrating in the thickness direction is formed in the roof material 4, the support member 7 is placed on the upper surface of the roof material 4, and the through hole 25 and the female screw hole 13 are aligned. Thereafter, the binding material 21 of the load receiving member 8 is inserted into the through hole 25 from the lower side of the roof material 4, and the binding material 21 is inserted while being screwed into the female screw hole 13 from the lower side. Thereafter, a nut 26a for preventing loosening is screwed onto the bonding material 21 protruding above the substrate 9 of the support member 7. In this manner, the support member 7 can be attached to the roof material 4 with the pair of load receiving members 8. A predetermined number of roofing materials 4 to which the supporting member 7 and the load receiving material 8 are attached are prepared.

Next, the normal roof material 4 to which the support member 7 and the load receiving material 8 are not attached and the roof material 4 to which the support member 7 and the load receiving material 8 are attached are installed on the roof base 3. In this case, a plurality of roof materials 4 are arranged vertically and horizontally on the roof base 3, but the roof materials 4 and 4 adjacent in the inclination direction of the roof base 3 (for example, the eaves-and-ridge direction) The front end portion of the roof material 4 on the side) is overlapped on the rear end portion of the roof material 4 on the other side (eave side). Further, the roof material 4 to which the support member 7 and the load receiving material 8 are attached can be arranged at a predetermined position of the roof base 3. In this case, the insertion hole 14 provided in the substrate 9 of the support member 7 is viewed from above. A fixing tool 26b such as a screw is driven. Since the fixture 26b is driven into the roof base 3, it is preferable to dispose the support member 7 above the roof structure material 5 so that the fixture 26b can be driven deeper. In addition, it is preferable to provide a hole or a recess in the roof material 4 at the position of the insertion hole 14 so that the fixing member 26b can be easily driven into the roof material 4. When the roof material 4 to which the support member 7 and the load receiving material 8 are attached in this manner is installed on the roof base 3, the lower leg material 22 of the load receiving material 8 is brought into contact with the upper surface of the base plate 6 of the roof base 3. The Further, the angle of the bonding material 21 is adjusted with respect to the leg material 22 so that the axial direction of the bonding material 21 is substantially perpendicular to the surface direction of the substrate 9 in a state where the leg material 22 is in contact with the upper surface of the base plate 6. Is done. Therefore, the load applied to the support member 7 is less likely to be borne on the roof material 4 and is more likely to be borne on the roof base 3 through the load receiving material 8. Therefore, the roof material 4 is not easily damaged by the load applied to the support member 7.

  After the roof material 4 is installed as described above to form the roof surface 2, the functional member 1 is installed above the roof surface 2. The functional member 1 is provided with a holding member 27 such as a frame member or a rail member, and the holding member 27 is fixed to the support member 7. In this case, the holding member 27 and the support member 7 can be coupled by a bolt or the like screwed into the fixing screw portion 20 of the fixing portion 10 of the support member 7. And the functional member 1 can be installed by arrange | positioning the holding member 27 so that it may span over the several support member 7 provided in the roof surface 2. FIG.

The construction method of the roof material 4 as described above has various structures depending on the construction site. For example, as shown in FIG. 3A, a tile rail 28 can be provided between the rear end portion of the roof material 4 and the roof base 3. Further, as shown in FIG. 3B, it is possible not to provide the tile rail 28 between the rear end portion of the roof material 4 and the roof base 3. Furthermore, as shown in FIG. 3C, the working width can be adjusted by expanding and contracting the overlapping dimension of the adjacent roof materials 4 and 4. In FIG. 3, the fixing part 10, the fixing tool 26 b , the functional member 1, and the like of the support member 7 are not shown. 3A to 3C described above, the dimension between the roof material 4 and the roof base 3 changes depending on the presence or absence of the tile rail 28. In addition, the dimension between the roof material 4 and the roof base 3 also changes depending on the thickness of the roof tile 28. Furthermore, the dimension between the roofing material 4 and the roof base 3 also changes depending on the overlapping dimensions of the adjacent roofing materials 4 and 4, and the inclination angle of the roofing material 4 provided with the support member 7 with respect to the roof base 3 is also changed. Change.

  In the present embodiment, even when the dimension between the roof material 4 and the roof base 3 and the inclination angle of the roof material 4 provided with the support member 7 are changed, the support member 7 and the load receiving material 8 are screwed together. By adjusting the position and the angle of the support member 7 and the load receiving member 8, the load applied to the support member 7 can be easily borne by the roof base 3 through the load receiving member 8. Therefore, the construction according to the construction site is easy to perform, and it is possible to prevent trouble.

  FIG. 4 shows another embodiment. Also in this embodiment, the support member 7 and the load receiving material 8 are used. The support member 7 can be formed in the same manner as described above. The load receiving member 8 is made of a metal such as a steel material as described above, and is provided with a binding member 21 and a leg member 22. The binding material 21 is formed of a bolt having a male screw on the outer periphery. As shown in FIG. 5, the leg material 22 has a top surface formed as a curved surface 29. The curved surface 29 is a concave curved surface having a substantially constant radius of curvature, and is formed so as to gradually increase from the center portion of the leg member 22 toward the front end portion and the rear end portion. The lower surface of the leg member 22 is formed as a flat surface. The binding material 21 and the leg material 22 are not integrated, and are used for construction in separate states.

And in installing the functional member 1 in the roof surface 2, it can carry out as follows. First, the support member 7 and the binding material 21 of the load receiving material 8 are attached to the roof material 4 on which the functional member 1 is placed. In this case, a through hole 25 penetrating in the thickness direction is formed in the roof material 4, the support member 7 is placed on the upper surface of the roof material 4, and the through hole 25 and the female screw hole 13 are aligned. Thereafter, the bonding material 21 is inserted into the through hole 25 from the lower side of the roof material 4, and the bonding material 21 is inserted into the female screw hole 13 while being screwed from the lower side. Thereafter, a nut 26a for preventing loosening is screwed onto the bonding material 21 protruding above the substrate 9 of the support member 7. In this way, the support member 7 can be attached to the roof material 4 with the pair of bonding materials 21. A predetermined number of roofing materials 4 to which the supporting member 7 and the binding material 21 are attached are prepared.

Next, the normal roof material 4 to which the support member 7 and the bonding material 21 are not attached and the roof material 4 to which the support member 7 and the bonding material 21 are attached are installed on the roof base 3. In this case, a plurality of roof materials 4 are arranged vertically and horizontally on the roof base 3, but the roof materials 4 and 4 adjacent in the inclination direction of the roof base 3 (for example, the eaves-and-ridge direction) The front end portion of the roof material 4 on the side) is overlapped on the rear end portion of the roof material 4 on the other side (eave side). Moreover, the leg material 22 of the load receiving material 8 can be arrange | positioned in the predetermined position of the roof base | substrate 3, and the roof material 4 to which the supporting member 7 and the coupling material 21 were attached can be arrange | positioned above it. In this case, similarly to the above, a fixing tool 26b such as a screw is driven into the insertion hole 14 provided in the substrate 9 of the support member 7 from above. When the roof material 4 to which the support member 7 and the bonding material 21 are attached in this way is installed on the roof base 3, the lower end of the bonding material 21 is brought into contact with and joined to the curved surface 29 on the upper surface of the leg material 22. Thereby, the leg member 22 at the lower end of the load receiving member 8 comes into contact with the upper surface of the base plate 6 of the roof base 3. Further, the lower end of the binding material 21 is formed to be movable along the curved surface 29 of the leg member 22 in a state where the leg member 22 is in contact with the upper surface of the base plate 6. Therefore, the angle of the binding material 21 is adjusted with respect to the leg material 22 so that the axial direction thereof is substantially perpendicular to the surface direction of the substrate 9. Thereby, the load applied to the support member 7 is less likely to be borne by the roof material 4, and is easily borne by the roof base 3 through the load receiving material 8. Therefore, the roof material 4 is not easily damaged by the load applied to the support member 7.

  After laying the roof material 4 in this way to form the roof surface 2, the functional member 1 is installed above the roof surface 2 in the same manner as described above.

Also in the present embodiment, the method of constructing the roof material 4 has various structures depending on the construction site. For example, as shown in FIG. 6A, a tile rail 28 can be provided between the rear end portion of the roof material 4 and the roof base 3. In addition, as shown in FIG. 6B, it is possible not to provide the tile rail 28 between the rear end portion of the roof material 4 and the roof base 3. Furthermore, as shown in FIG. 6C, the working width can be adjusted by expanding and contracting the overlapping dimension of the adjacent roof materials 4 and 4. In FIG. 6, the fixing part 10, the fixing tool 26 b , the functional member 1, and the like of the support member 7 are not shown. 6A to 6C described above, the dimension between the roof material 4 and the roof base 3 changes depending on the presence or absence of the tile rail 28. In addition, the dimension between the roof material 4 and the roof base 3 also changes depending on the thickness of the roof tile 28. Furthermore, the dimension between the roofing material 4 and the roof base 3 also changes depending on the overlapping dimensions of the adjacent roofing materials 4 and 4, and the inclination angle of the roofing material 4 provided with the support member 7 with respect to the roof base 3 is also changed. Change.

  And in this Embodiment, even if it is a case where the inclination angle of the roofing material 4 which provided the dimension between the roofing material 4 and the roof base | substrate 3, and the supporting member 7 changes, of the supporting member 7 and the load receiving material 8 By adjusting the screwing position and the angle between the support member 7 and the load receiving member 8, the load applied to the support member 7 can be easily borne by the roof base 3 through the load receiving member 8. Therefore, the construction according to the construction site is easy to perform, and it is possible to prevent trouble.
