FIG. 3 is an exploded perspective view showing the configuration of the roof 10 around the antenna 41. In FIG. 3, the rafter 22, the field plate 23, the purlin bracket 31, the fixing bolt 32, the connection reinforcing member 33, the crosspiece 35, the support fixture 43, and the waterproof member 57 are not shown.

  As shown in FIG. 3, the antenna 41 corresponds to an electrical device as a relatively small building facility, and is attached to an upper end portion of an antenna column 42 as a support member erected on the roof 10. The antenna column 42 is a steel pipe column formed of a metal material, and is fixed to the purlin 21 by a column fixing tool 43 in a state of penetrating the ridge tile 24a and the purlin 21 up and down. Thereby, the fixing strength of the antenna support 42 with respect to the purlin 21 is increased.

  The purlin 21 and the roof tile 24a are respectively provided with column insertion holes 45 and 46 for inserting the antenna column 42, and these column insertion holes 45 and 46 are arranged side by side so as to be in communication with each other.

In the purlin 21, support post insertion holes 45 are provided in the respective flanges 21 b, and any support post insertion holes 45 are arranged vertically so as to communicate with the support post insertion holes 46 of the roof tile 24 a. .

  In addition to the purlin 21 and the roof tile 24a, the antenna column 42 penetrates the receiving bracket 37 vertically, and the receiving bracket 37 is also provided with insertion holes that communicate with the column insertion holes 45 and 46 of the purlin 21 and the roof tile 24a. ing.

  Incidentally, the antenna 41 constitutes electrical equipment and building facilities. Moreover, the support | pillar insertion hole 45 formed in the purlin 21 corresponds to a purlin hole, and the support | pillar insertion hole 46 formed in the roof tile 24 corresponds to a finishing material hole.

  The antenna 41 is electrically connected to an audiovisual device installed in the building by an antenna cable 51 as electric wiring. A cable connector 52 for the antenna cable 51 is provided in the building, and the antenna cable 51 is connected to the audiovisual device by being connected to the cable connector 52. The cable connector 52 is housed in a connector case 53, and the connector case 53 is provided below the purlin 21. In this case, the connector case 53 is provided in the attic space.

  The antenna cable 51 has one end connected to the antenna 41 and the other end connected to the cable connector 52 while being inserted into the hollow portion of the antenna support 42. The antenna support 42 is provided with a cable lead-out port 55 as a wiring lead-out port at each of an upper end portion and a lower end portion thereof. In this case, the upper cable outlet 55 is disposed outdoors, and the end of the cable connected to the antenna 41 is drawn from the cable outlet 55. On the other hand, the lower cable outlet 55 is disposed indoors, and the end of the cable connected to the cable connector 52 is drawn from the cable outlet 55. The outdoor cable outlet 55 is provided with a draining structure such as a waterproof hood.

  A waterproof member 57 formed of an elastic material such as rubber is attached to the antenna column 42 in the column insertion hole 46 of the roof tile 24a. The waterproof member 57 has a waterproof property, and provides a waterproof function to the gap between the inner peripheral surface of the column insertion hole 46 and the outer peripheral surface of the antenna column 42.

  The column fixing tool 43 is disposed on the lower surface side of the lower flange 21b of the purlin 21 and fixes the lower end portion of the antenna column 42 to the lower flange 21b. The support fixture 43 includes a first contact part 43a that contacts the peripheral surface of the antenna support 42 and a second contact part 43b that contacts the lower surface of the lower flange 21b. The portion 43a is fixed to the lower end portion of the antenna column 42 with screws or the like, and the second contact portion 43b is fixed to the lower flange 21b with bolts or the like.

  In the present embodiment, a plurality of support insertion holes 45 are arranged side by side along the longitudinal direction of the purlin 21 in the purlin 21. In this case, even if the purlin 21 is not processed to newly form the column insertion hole 45, the antenna column 42 extends in the direction in which the building 12 extends by changing the attachment target of the antenna column 42 to another column insertion hole 45. The mounting position of can be changed. In the receiving metal fitting 37, a plurality of through holes penetrating vertically through the receiving metal fitting 37 are provided in accordance with the respective column insertion holes 45 of the purlin 21.

  In the roof tile 24a, the column insertion hole 46 is provided in a portion where the antenna column 42 is erected, but is not provided in a portion where the antenna column 42 is not erected. On the other hand, as described above, each of the ridge tiles 24a has substantially the same size and shape, so that the positions of the ridge tile 24a with the column insertion holes 46 and the ridge tile 24a without the column insertion holes 46 are switched. Thus, the position of the column insertion hole 46 can be changed. The roof tile 24a with the column insertion holes 46 corresponds to the perforated material, and the roof tile 24a without the column insertion holes 46 corresponds to the perforated material.

  In the purlin 21, each pillar insertion hole 45 is arranged in accordance with the roof tile 24 a existing above each. In this case, each column insertion hole 45 is arranged so that the relative positional relationship with the roof tile 24 a existing above each column is the same for all column insertion holes 45. Specifically, the plurality of ridge tiles 24 a are arranged at positions determined by a predetermined dimension L along the longitudinal direction of the ridger 21 above the ridger 21, and the column insertion holes 45 of the ridger 21 are predetermined. They are arranged at intervals of the dimension L. The predetermined dimension L corresponds to the width of the roof tile 24a.

  Here, the support insertion holes 45 may be provided corresponding to some of the roof tiles 24a. For example, in the purlin 21, the column insertion hole 45 may be disposed below the n-th building tile 24 a from the building tile 24 a having the column insertion hole 46. In this case, the interval between the adjacent column insertion holes 45 is n times (L × n) the predetermined dimension L. Incidentally, n is a natural number.

  The predetermined dimension L is the length dimension of the portion where the roof tile 24a is exposed upward in the longitudinal direction of the purlin 21. Therefore, when the adjacent ridge tiles 24a are provided in a state where a part of each other is overlapped, the predetermined dimension L is the difference between the width dimension of the ridge tile 24a and the overlap width of the adjacent ridge tiles 24a. When the ridge tile 24a does not overlap, the predetermined dimension L is the width dimension of the ridge tile 24a.

  As described above, since each pillar insertion hole 45 of the purlin 21 is arranged in accordance with the roof tile 24a, even when the roof tile 24a with the pillar insertion hole 46 is installed above any pillar insertion hole 45, The pillar insertion hole 46 of the ridge tile 24a communicates with the pillar insertion hole 45 of the purlin 21 vertically. Moreover, the column insertion hole 46 can be increased by replacing the existing roof tile 24a without the column insertion hole 46 with the new building tile 24a with the column insertion hole 46.

  The connector case 53 is formed in a long shape, and is disposed below the purlin 21 so as to extend along the longitudinal direction of the purlin 21. A plurality of cable connectors 52 are provided in the connector case 53, and are arranged side by side along the longitudinal direction of the purlin 21 so as to correspond to the column insertion holes 45 of the purlin 21. In this case, even if the antenna column 42 is fixed to the plurality of column insertion holes 45 in the purlin 21, the cable connector 52 is disposed in the vicinity of the cable outlet 55 at the lower end portion of the antenna column 42.

  Next, an operation procedure for changing the position of the antenna 41 will be described.

  First, the antenna 41 is removed together with the antenna support 42 from the current position. Specifically, the antenna cable 51 is extracted from the cable connector 52 in the attic space and is extracted from the hollow portion of the antenna support 42. Further, the support fixture 43 is removed from both the antenna support 42 and the purlin 21 in the attic space, and the antenna support 42 is extracted from the support insertion holes 45 and 46 of the purlin 21 and the roof tile 24a toward the roof.

  Thereafter, in order to transfer the column insertion hole 46 of the ridge tile 24a, the ridge tile 24a as the transfer source and the ridge tile 24a as the transfer destination are replaced. Then, the antenna support 42 is inserted from above the roof into the support insertion holes 45 and 46 of the purlin 21 and the roof tile 24a at the transfer destination, and the antenna support 42 is fixed to the purlin 21 by attaching the support fixture 43 in the attic space. . Further, the antenna cable 51 is inserted from the cable outlet 55 at the upper end of the antenna support 42, pulled out from the cable outlet 55 at the lower end, and the antenna cable 51 is inserted into the nearby cable connector 52.

  When the antenna 41 is added, the existing roof tile 24a is replaced with the new roof tile 24a having the new column insertion hole 46 at the expansion destination, the antenna 41 is attached to the antenna column 42, and the antenna column 42 is moved in the same manner. Installation of the antenna support 42 and connection work of the antenna cable 51 are performed. In this case, the position of the column insertion hole 46 in the new roof tile 24a is the same as that of the existing roof tile 24a. That is, the column insertion holes 46 are arranged at predetermined positions in any of the roof tiles 24a. For this reason, the column insertion holes 45 and 46 of the ridge tile 24a and the timber 21 are arranged vertically even at the position where the new ridge tile 24a is attached.

  When a solar panel 61 that performs solar power generation is installed on the roof 10, the solar panel 61 may be supported by the purlin 21. Here, the support structure of the solar panel 61 will be described with reference to FIG. 4A and 4B are diagrams showing the configuration of the roof 10 around the solar panel 61. FIG. 4A is a plan view of the roof 10, and FIG. 4B is a longitudinal sectional view of the roof 10 around the purlin 21. FIG.

  As shown to Fig.4 (a), (b), the solar panel 61 is each installed on the roof 10 on a pair of inclined roof part 10a. In each inclined roof portion 10a, the solar panels 61 are respectively arranged below the ridge 12 so as to extend along the longitudinal direction of the purlin 21. In this case, the upper end portions of the solar panels 61 are gathered on the ridge 12 side of the roof 10. The solar panel 61 corresponds to a relatively large building facility.

  The column insertion holes 45 of the purlin 21 are provided on both ends of the flange 21b with the web 21a interposed therebetween, and are arranged side by side along the longitudinal direction of the purlin 21 on each of the both ends. Similarly, the column insertion holes 46 of the ridge tile 24a are also provided on both sides of the ridge 12, and are arranged side by side along the longitudinal direction of the purlin 21 on both sides. In this case, the plurality of ridge tiles 24 a having the column insertion holes 46 are arranged above the plurality of column insertion holes 45 of the purlin 21.

  In a plurality of locations in the longitudinal direction of the purlin 21, the panel column 62 that supports the solar panel 61 is fixed in a state in which the panel column 62 is inserted into the column insertion holes 45 and 46 of the purlin 21 and the roof tile 24 a like the antenna column 42. The tool 43 is fixed to the purlin 21. The panel column 62 is a steel tube column made of a metal material, similarly to the antenna column 42, and has cable outlets 55 at both upper and lower ends.

  The upper end portion of each panel support 62 is connected to the upper end portion of the solar panel 61 by a connecting tool 63 such as a wire. In this case, the solar panel 61 is supported by the purlin 21 via the plurality of panel columns 62 in each of the pair of inclined roof portions 10a.

  The solar panel 61 is electrically connected to a power storage device or a power supply device installed in the building by a power cable 65 as electrical wiring. The power cable 65 is inserted into the hollow portion of at least one panel column 62 among the plurality of panel columns 62, one end is connected to the solar panel 61, and the other end is a power storage device or a power supply unit in the building. It is connected to the.

  In the configuration in which the solar panels 61 are installed on each of the pair of inclined roof portions 10a, the upper ends of the solar panels 61 are gathered on the ridge 12 side. This is convenient for connecting the optical panel 61 to the purlin 21. For example, since the solar panel 61 is fixed to the purlin 21 having a high structural strength, even the solar panel 61 having a relatively large weight can be favorably supported. Furthermore, it can suppress that the support structure of the solar panel 61 becomes complicated.

  According to the embodiment described in detail above, the following excellent effects can be obtained.

  In the configuration in which the antenna column 42 is installed in a state of penetrating the purlin 21 and the tile 24a, a plurality of column insertion holes 45 are arranged along the longitudinal direction of the purlin 21 in the purlin 21, and the column insertion holes of the ridge tile 24a are arranged. The position 46 can be changed. For this reason, the installation position of the antenna column 42 in the longitudinal direction of the purlin 21 can be changed without changing the fixing method of the antenna column 42 by an easy operation of changing the insertion target of the antenna column 42 to the other column insertion holes 45 and 46. Can be changed. Similarly, by adding the column insertion hole 46 of the roof tile 24a, the antenna column 42 can be expanded by an easy operation of inserting the new antenna column 42 into the column insertion holes 45 and 46.

  Further, when the solar panel 61 is installed on the roof 10, the purlin 62 is inserted into the column insertion holes 45 and 46 at a plurality of positions along the longitudinal direction of the purlin 21. The solar panel 61 is supported by these panel support columns 62. Here, the purlin 21 is strong enough to support the plurality of rafters 22. Therefore, even if the plurality of panel columns 62 are fixed, any of the panel columns 62 can be suitably supported.

  As a result, the building facilities installed on the roof 10 can be favorably supported.

  The antenna cable 51 inserted through the hollow portion of the antenna column 42 can be pulled out from the cable outlet 55 at the upper and lower ends of the antenna column 42 above and below the ridge tile 24a. For this reason, the installation method of the antenna cable 51 can be unified in addition to the fixing method of the antenna column 42 in each place where the column insertion holes 45 and 46 are provided. Therefore, in addition to the installation work of the antenna support 42, the installation work of the antenna cable 51 can be facilitated. The same applies to the installation work of the panel support 62 and the installation work of the power cable 65 when the solar panel 61 is installed.

Since it is assumed that the antenna cable 51 is connected to the cable connector 52, the installation work of the antenna 41 can be further facilitated.

  The column insertion hole 46 can be moved by changing the position of the roof tile 24a having the column insertion hole 46. In this case, in the configuration in which a plurality of column insertion holes 45 are provided in the purlin 21, it is not necessary to form the column insertion hole 46 by processing the building tile 24 a with respect to the installation position of the antenna column 42. The transfer work and expansion work of the hole 46 can be facilitated. That is, the work of forming the column insertion hole 46 of the ridge tile 24a according to the column insertion hole 45 of the purlin 21 can be facilitated.

  In the configuration in which each of the roof tiles 24a is arranged with a predetermined dimension L, since each pillar insertion hole 45 of the purlin 21 is arranged at an interval of L × n (n is a natural number), any of the roof tiles 24a has the pillar insertion hole 46. Even if the ridge tile 24a is provided, the pillar insertion holes 45 and 46 of the ridge tile 24a and the purlin 21 can be arranged side by side. In this case, since the positions of the ridge tiles 24a can be interchanged, it is not necessary to use the new ridge tile 24a when changing the position of the column insertion hole 46. Therefore, cost reduction can be achieved for the transfer of the column insertion hole 46.
