Description

  TECHNICAL FIELD The present invention relates to an installation structure for a roofed structure attached to a roof of a building such as a house.

  In recent years, it is common practice to install roofing structures such as solar panels (PV panels), water heaters, and receivers on the roofs of buildings such as houses. Various methods for stable and easy installation have been proposed. For example, when installing a solar cell panel on a roof where a roof tile is installed, a mounting frame is attached to the roof tile in advance, and a solar cell panel is installed on the mounting frame to improve construction efficiency. The installation state is stabilized (for example, see Patent Document 1).

  Alternatively, as shown in FIG. 8, a metal roof material 10 having a plurality of protrusions 11 is laid on a roof base 30, and a roof attachment 20 (sun A base 40 for attaching a battery panel) is fixed, and a roofed article 20 is installed on the base (for example, see Patent Document 2). In FIG. 8A, the gantry 40 is omitted. By installing the roofed article 20 on the metal roof material 10 in this manner, the cost can be reduced as compared with the building material-integrated solar battery panel, and the degree of freedom in construction can be improved.

Japanese Patent Laid-Open No. 11-247378 JP 2007-217904 A

  However, in the case of the structure as disclosed in Patent Document 1, it takes time to mount the gantry frame after rolling the roof tile, and the load on the solar cell panel is directly applied to the roof tile itself, which may damage the roof tile. There was something. Furthermore, since it becomes a structure where a solar cell panel is installed on the roof tile, the solar cell panel has a structure that protrudes greatly above the surrounding roof tile, and the design of the roof is impaired. Also occurs. Moreover, when attaching the mount frame 40 on a roof tile, there also exists a problem that it must work on the roof tile with an unstable scaffold. On the other hand, in the roof having the structure as in Patent Document 2, the metal roof material 10 is visually recognized from the outside, so that it is not suitable for a roof of a house or the like due to a design problem. There also arises a problem that the battery panel protrudes greatly above the periphery. Furthermore, once the metal roofing material 10 is damaged, the waterproofness of the roof may be reduced.

  The present invention has been made in view of the above points, and even if a roofed structure such as a solar battery panel is installed, the appearance of the roof is not easily damaged, and the waterproof property is not easily lowered, and the construction is easy. It is an object of the present invention to provide an installation structure for a roofed article that can stably install a roofed article.

  In the installation structure of the roof attachment according to the present invention, the roof attachment is placed on the upper surface of the metal roof material laid on the roof base, and the upper surface of the metal roof material around the roof attachment. A plurality of roof tiles are spread to cover the metal roof material.

  Moreover, in the installation structure of the above-described roof attachment, the metal roofing material has ridges and flat portions alternately formed in a direction perpendicular to the eaves-ridge direction of the roof, and the roof tile is a mountain portion. The valleys are alternately formed to have a substantially wavy shape, and the distance between the adjacent ridges and the distance between the adjacent ridges of the metal roofing material are substantially the same length. Preferably it is formed.

  Moreover, it is preferable that the installation height of the said attachment with a roof and the installation height of the said roof tile are substantially the same height.

  In the installation structure of the roof attachment according to the present invention, the roof attachment is installed on the metal roof material and the roof tiles are laid around the roof attachment, so that the appearance of the roof is not easily damaged, and the waterproof property is provided. Is easy to install, and can be used for stable installation of roofed objects.

FIG. An example of embodiment of the base which can be used with the installation structure of the roof attachment of this invention is shown, (a) is a front view, (b) is a side view. It is sectional drawing which shows an example of embodiment of the roof which has the installation structure of the roof attachment of this invention, (a) is an enlarged view near roof attachment, (b) is an enlarged view of the eaves part of a roof. . It is sectional drawing which shows other embodiment of a roof same as the above and shows the vicinity of the side edge of a roof attachment. (A), (b) is the schematic explaining a part of construction method of the roof same as the above. The prior art example of the installation structure of a roof attachment is shown, (a) is the perspective view, (b) is the sectional drawing.

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

  FIG. 1: shows an example of embodiment of the roof which has the installation structure of the roof attachment of this invention, (a) shows a partial perspective view, (b) shows a- in (a). It is the figure which showed the cut surface seen from the eaves side of the roof of a cross section, and expanded one part. In addition, the direction of the block arrow in Fig.1 (a) has shown the direction which goes to the ridge side from the eaves edge of a roof. In the installation structure of the roofed article of the present invention, the metal roofing material 10 laid on the roof base 30, the roofed article 20, and the roof tile 1 are provided.

The metal roofing material 10 can use what was formed in the desired shape by processing a flat metal plate by roll forming or the like. For example, a metal plate having a thickness (plate thickness) of 0.3 to 0.5 mm and a weight per area of 3 to 6 kg / m ² can be suitably used. Moreover, as a kind of metal plate, various things, such as a coated steel plate, a galvanized steel plate, a coated galvalume steel plate (trademark), can be used, and it is preferable that it is especially comprised with the nonflammable material.

  Although the metal roof material 10 can be made into an appropriate shape, as in the embodiment of FIG. 1, on the surface of the metal roof material 10, the ridge portion 11 and the flat plate portion extend in a direction orthogonal to the eaves direction of the roof. It is preferable to use a metal roofing material 10 having a substantially wavy cross section in which 12 and 12 are alternately and repeatedly formed. In this case, the roofed article 20 can be more stably installed, and the roof tile 1 can be easily spread as described later. In addition, the eaves direction of a roof shows the same direction as the inclination direction of a roof.

  The ridge portion 11 is formed so that the metal plate is bent and protrudes upward (in a direction opposite to the roof base 30). Such ridges 11 can be formed over substantially the entire length of the metal roof material 10, for example. Usually, the metal roof material 10 is laid on the roof base 30 so that the extending direction of the ridges 11 is along the eaves-ridge direction. Hereinafter, in the present specification, in the metal roof material 10, the extending direction of the ridges 11 is “the vertical direction of the metal roof material 10”, and the surface of the metal roof material 10 is the direction perpendicular to the vertical direction “metal”. Sometimes referred to as the “lateral direction of the roofing material 10”. That is, the vertical direction and the eaves direction indicate the same direction.

  A plurality of ridges 11 are formed with a predetermined interval in the lateral direction of the metal roof material 10, and the ridges 11 adjacent in the lateral direction are arranged substantially parallel to each other. And between the adjacent protruding item | line parts 11 and 11, it is formed over the substantially whole length of the vertical direction of the metal roof material 10 as the substantially flat flat plate part 12. FIG. Both side surfaces of the ridge 11 may be formed as inclined surfaces. That is, the ridge portion 11 may be formed so as to be inclined downward from the top surface side end to the flat plate portion 12. Of course, you may form so that it may hang down to the flat plate part 12 from said top surface side end.

  In the installation structure of the roofed article of the present invention, a plurality of metal roof materials 10 may be laid on the roof base 30. In the case of the metal roof material 10 in which the ridges 11 and the flat plate parts 12 are formed as described above, the ridges 11 of the adjacent metal roof materials 10 and 10 are laid so as to overlap each other. That's fine. Thus, if the metal roof material 10 is laid, it will become excellent in waterproofness and stability of a laid state.

  The metal roofing material 10 can be manufactured by, for example, a known roll forming machine, may be manufactured by a bender processing machine, and end processing may be performed by hemming bending or pressing. The vertical and horizontal dimensions of the metal roof material 10 may be set as appropriate in accordance with the area of the roof base 30 and the like. For example, the vertical length may be 1000 to 2500 mm, and the horizontal direction may be 300 to 1100 mm. .

  The metal roof material 10 should just be laid in the range wider than the area | region in which the roof attachment 20 is mounted, and of course, may be laid over the substantially whole surface of the roof base | substrate 30. The metal roof material 10 can be fixed to the roof base 30 with, for example, screws.

  As the roof base 30, for example, a base material formed by laying a base plate on a main building material, or a base material composed of a pier, a waterproof sheet, a base plate, a rafter, or the like can be used. Moreover, you may make it lay a waterproof sheet etc. as needed.

  As shown in FIG. 1, a roofed article 20 is installed on the upper surface of the metal roof material 10. When the metal roofing material 10 having the plurality of ridges 11 is laid as described above, the roofed article 20 is installed on the top surface of the plurality of ridges 11.

  Examples of the roofed article 20 include a power supply device such as a solar cell panel (also referred to as a solar cell module), a hot water supply system device, a ventilation device, a snow melting device, a receiving device, and the like. In addition, in FIG. 1, the solar cell panel 2 is shown as an example of the structure 20 with a roof. The solar cell panel 2 may be configured by a plurality of panel units. In this case, the solar cell panels 2 can be configured by connecting the panel units to each other (in this embodiment, 4 units). Composed of). As will be described later, the panel units can be connected to each other by interposing a connecting member that enables connection between the panel units (see FIG. 5A described later).

  The roofed article 20 can be fixed to the metal roofing material 10 using, for example, screws, screws, bolts, and the like, and a fixing method may be selected according to the type and structure of the roofed article 20. In the case of the solar cell panel 2, the solar battery panel 2 is usually composed of a light receiving part and a surrounding frame (reinforcing member), and a metal roof is formed by inserting screws, bolts and the like into the frame. It can be fixed to the material 10. For example, a screw or the like can be driven into the frame body, the metal roofing material 10 can be penetrated, and the roofed article 20 can be connected to the metal roofing material 10.

  The roof tile 1 is wound around the upper surface portion of the metal roofing material 10 around the roofed structure 20 and on which the roofed structure 20 is not placed (also referred to as being laid). In other words, in the metal roofing material 10, when the region where the roofing fixture 20 is installed (or the region where the roofing fixture 20 occupies the upper surface of the metal roofing material 10) is set as the “installation region”, this installation is performed. The roof tile 1 is sown in an area other than the area (referred to as “non-installation area”). In addition, when there is a portion of the roof base 30 where the metal roof material 10 is not laid, the roof tile 1 may also be installed in the roof base 30 portion. In short, the roof tile 1 can be spread over portions other than the installation area.

  The roof tile 1 may be formed of a metal material or may be formed of an inorganic material such as cement. In addition, the shape and size of the roof tile 1 are not particularly limited as long as the effect of the present invention is not hindered. For example, the roof tile 1 having a substantially corrugated cross section can be used. Such a roof tile 1 has a mountain part 1a and a valley part 1b. A plurality of peaks 1a and valleys 1b may be formed while being alternately repeated. Such a substantially wave-like roof tile 1 also improves the design of the roof, and is excellent in drainage properties such as rainwater.

  The roof tile 1 can be fixed with screws, screws, bolts, and the like. For example, the roof tile 1 may be inserted from the mountain portion 1a of the roof tile 1 to penetrate the metal roof material 10 and the roof base 30.

  Further, a cover member 32 for preventing intrusion of rainwater or the like may be provided between the side end portion of the roofed article 20 and the roof tile 1. The configuration of the cover member 32 will be described later (see FIG. 3B described later).

  As shown in FIG. 2, the roof tile 1 is wound on the non-installation area of the metal roof material 10 (the upper surface portion of the metal roof material 10 on which the roofed article 20 is not placed), so that this non-installation area is It is covered with the roof tile 1. In FIG. 2, in order to clarify that the roof tile 1 is spread on the metal roof material 10, the roof tile 1 is shown in a partially removed state. As shown, the non-installation area of the metal roof material 10 is covered. Thus, the metal roofing material 10 is in a state of being covered with the roofed article 20 placed in the installation area and the roof tile 1 installed in the non-installation area. It is in a state where the metal roofing material 10 is not clearly visible.

  Since the non-installation area of the metal roof material 10 is covered and covered by the roof tile 1 being rolled as described above, the metal roof material 10 laid on the roof base 30 can be made invisible from the outside. The design of the roof appearance is excellent. In a building such as a house, when a member such as the metal roofing material 10 is clearly visually recognized on the appearance, there is a possibility that the design property may be lacking. However, the installation structure of the roof attachment according to the present invention is applied to the roof. Then, since the metal roof material 10 cannot be seen, it is possible to form a roof that gives a natural impression. Further, since the roofed article 20 is not placed on the roof tile 1, the installation state of the roofed article 20 becomes stable, and the roof tile 1 is not damaged by the load of the roofed article 20. Moreover, the roof tile 1 is spread on the metal roof material 10 to improve the waterproof property of the roof itself, and a roof having a double waterproof function is formed with the lower metal roof material 10. Become.

  In the roof tile 1 having a substantially wavy cross section, the length (distance) between the adjacent ridges 1a is substantially the same as the length (distance) between the adjacent ridges 11 in the metal roof material 10. It is preferable that the length L is formed. The length between the adjacent peak parts 1a here means the shortest distance between the peak part 1c of the peak part 1a and the peak part 1c of the peak part 1a adjacent to the peak part 1a. The top part 1c refers to the highest part of the peak part 1a. Moreover, the length between adjacent protruding item | line parts 11 means the shortest distance from the top surface center part of the protruding item | line part 11 to the top surface center part of the protruding item | line part 11 adjacent to this. In the case of the roof tile 1 formed in this way, as shown in FIG. 1 (b), the mountain portion 1a of the roof tile 1 and the protruding strip portion 11 of the metal roof material 10 are opposed to each other vertically. The roof tile 1 is rubbed, and the valley portion 1b is rubbed against (contacts with) the upper surface of the flat plate portion 12. By being configured as described above, the appearance of the entire roof is improved, so that the design is further improved, and only the metal roofing material 10, the roof tile 1, and the roofing fixture 20 are provided on the roof base 30. Since the roof can be formed with this structure, the roof can be easily accommodated.

  The length between the above-mentioned peak parts 1a in roof tile 1 can be 200-350 mm, for example, and the length between the above-mentioned convex strip parts 11 in metal roofing material 10 can be 200-350 mm. However, it is not limited to these.

  As shown in FIG. 1 (b), the roof tile 1 further includes a plane passing through the top 1c of each roof tile 1 installed, and a roof attachment 20 ( The roof tile 1 is preferably formed so that the top surfaces of the solar cell panels 2) are substantially flush with each other. That is, it is preferable that the roofed article 20 does not protrude greatly with respect to the roof tile 1 sown around this. In this case, the entire roof surface becomes more integrated, and the design of the roof can be further improved. Moreover, even if a strong wind is blown on the roof because the roofed article 20 does not protrude larger than the surroundings, the roof tile 1 can reduce the influence of the wind from the eaves building direction on the roofed article 20, The vibration of the roofed article 20 can be suppressed. Therefore, the installation state of the roofed article 20 is stable over a long period of time. Here, the height H1 from the surface of the roof base 30 to the top surface of the roof attachment 20 (referred to as the installation height H1 of the roof attachment 20), and the top surface (top 1c) of the roof tile 30 from the surface of the roof base 30. If the difference from the height H2 (referred to as the installation height H2 of the roof tile 1) is within ± 20 mm, there is no problem. Of course, the difference between the installation height H1 of the roofing fixture 20 and the installation height H2 of the roof tile 1 is not limited to the above range, and depending on the shape of the roofing fixture 20 and the roof tile 1 and the like, It may be beyond the range as long as it is at least a deviation that does not impair the aesthetics.

  As shown to Fig.3 (a), the roof tile 1 can also employ | adopt the tile (for example, metal tile) formed in elongate, In this case, the workability of a roof can be improved. . Moreover, it is also possible to cut | disconnect and use for desired length. Such a long roof tile 1 is particularly suitable for spreading the roof tile 1 on the side of the roofed article 20 as shown in FIG. 3B, and can shorten the construction time. Become.

  FIG.3 (b) is sectional drawing which shows the roof storage of the side of the roof attachment 20, and represents the cut surface along the direction orthogonal to the eaves-ridge direction. A cover member 32 may be provided between the roofed structure 20 and the roof tile 1. The cover member 32 can be provided along substantially the entire length of the side end of the roofed article 20. The side edge part of the roofed article 20 here refers to the left and right side edges when the roofed article 20 is viewed from the roof eaves direction.

  The cover member 32 is formed by bending a metal plate or the like, for example. In this embodiment, the cover fixing part 32a fixed to the metal roofing material 10 and the cover part 32b covering the roof tile 1 adjacent to the roofed article 20 are formed. A part of the cover fixing portion 32a is disposed so as to be sandwiched between the roof attachment 20 and the metal roofing material 10, and the connector 5 that is driven into the roof attachment 20 penetrates the cover fixing portion 32a. The metal roof material 10 and the pedestal 3 are fixed. The connector 5 and the base 3 will be described later (see FIG. 5A). The cover portion 32b is bent at the tip of the cover fixing portion 32a to have a substantially L-shaped cross section and is arranged so as to cover one end portion of the roof tile 1 adjacent to the roofed article 20. It covers the valley 1b and peak 1a at the side edges. Further, one side end of the cover portion 32b is bent along the inclined surface of the peak portion 1a, and the tip end portion thereof is bent back and formed into a substantially U shape, and the cover member 32 is lifted by a strong wind. Is preventing.

  In addition, screws or the like are driven into the cover fixing portion 32a, and the cover fixing portion 32a is fixed by penetrating the mountain portion 1a of the roof tile 1, the metal roof material 10, and the roof base 30. When a screw or the like is driven into the cover fixing portion 32a, a packing member 60 may be interposed between the cover fixing portion 32a and the peak portion 1a as shown in FIG.

  By providing the cover member 32 in this manner, it is possible to prevent rainwater and the like from entering between the roof-attached structure 20 and the roof tile 1, and to further enhance the waterproof performance of the roof. Moreover, there exists an advantage which prevents that the metal roof material 10 is visually recognized from the outer side between the roofing thing 20 and the roof tile 1, and the design property can also be improved.

  Moreover, the base 3 may be provided in the roof base | substrate 30 like embodiment of FIG.3 (b). In this case, the pedestal 3 is arranged so as to be covered with the protruding strips 11 of the metal roof material 10 laid on the roof base 30. Hereinafter, the configuration of the base 3 will be described.

  As shown in FIG. 4, the pedestal 3 includes a base 3a having a convex shape (substantially inverted U-shaped cross section or a substantially inverted U-shaped cross section) and a flat plate extending outward from both ends of the base 3a. A substantially hat-shaped cross section having a pair of support portions 3b, 3b can be used. Such a pedestal 3 can be formed, for example, by bending a metal plate. Of course, the pedestal 3 may have a shape such as a rectangular column such as a rectangular parallelepiped or a cube other than the above-described substantially hat-shaped cross section. However, it is preferable to use the pedestal 3 having a substantially hat-shaped cross section as shown in FIG. 4 in that the state of attachment to the roof base 30 is stable and the weight does not become too large. Moreover, you may provide the protrusion part 3c which protruded upwards in the top surface of the base part 3a. Since the protrusion 3c is provided, when the metal roofing material 10 is laid on the top of the pedestal 3, the shape of the protrusion 3c is transferred to the surface of the metal roofing material 10. Therefore, the position of the pedestal 3 is changed. It is possible to grasp from above the metal roof material 10. The width M of the pedestal 3 is formed to be shorter than at least the lateral width of the top surface of the ridge 11 so that the ridge 11 can cover the pedestal 3.

  A plurality of pedestals 3 can be provided on the roof base 30, and can be attached and fixed by a fixing tool 6 such as a screw, for example. The fixing tool 6 may be driven into the roof base 30 from the support portion 3b. If a rafter 31 is provided below the roof base 30, the fixing tool 6 is also driven into the rafter 31. May be. Further, the pedestal 3 is arranged on the roof base 30 so that both side surfaces of the pedestal portion 3a face the eaves ridge direction side. A plurality of pedestals 3 may be provided while being separated along the extending direction of the ridges 11.

  As described above, since the pedestal 3 is fixed to the roof base 30, it is possible to prevent the metal roofing material 10 from being laterally shifted and to be a mark for alignment when the metal roofing material 10 is laid. The workability can also be improved.

  As illustrated in FIG. 3B, the roofing fixture 20 and the pedestal 3 can be connected to each other with the metal roofing material 10 (projection strip portion 11) interposed by the connector 5. In this case, for example, a bolt or the like is used as the connection tool 5, the connection tool 5 is driven into the roofed object 20, and the protruding portion 11 and the top portion of the base portion 3 a of the base 3 are penetrated. The roofed structure 20 and the pedestal 3 may be connected. By setting it as such a connection structure, the installation state of the roofing thing 20 can be made more stable.

  As shown in FIG. 5A, when the roofed article 20 is the solar battery panel 2, it can be connected to the base 3 using the support member 25. Here, Fig.5 (a) has shown the cut surface along the eaves-ridge direction of a roof, and is an enlarged view of solar cell panel 2 vicinity. Hereinafter, the connection to the base 3 of the solar cell panel 2 using the support member 25 will be described in detail. In the embodiment of FIG. 5 (a), each panel unit of the solar cell panel 2 is formed in a box shape with an opening at the bottom. For example, as in the known solar cell panel 2, the light receiving unit (Module) and the frame (reinforcing member) which covers this peripheral surface shall be comprised.

  The support member 25 is bent at a substantially right angle at the front end of the panel connection portion 25c and sandwiched between the panel units of the solar cell panel 2, and is arranged on the roof material 10 (projection strip portion 11). ) And a fixed portion 25b on a substantially flat plate fixedly arranged on the flat plate). In addition, the upper end of the panel connection portion 25c is formed with a pair of engagement pieces 25a and 25a having a substantially m-shaped cross section symmetrically to the left and right. The engaging pieces 25a are hooked and engaged with the engaged pieces 2a that can be engaged with the engaging pieces 25a formed on the frame of the solar cell panel 2, so that the units of the adjacent solar cell panels 2 are connected to each other. Can be connected. In addition, if the support member 25 is a piece shape, it can provide with two or more between adjacent panel units. The support member 25 may be formed in a long shape. In addition, the support member 25 is shown as an example, and of course may have other configurations, and particularly if it is formed in a configuration that allows the solar cell panel 2 and the roof material 10 to be connected. The shape is not limited.

  A connector 5 such as a screw, a screw, or a bolt is driven into the fixing portion 25b, and penetrates the top of the ridge portion 11 and the base portion 3a of the pedestal 3. By providing the connector 5 in this way, the solar cell panel 2 is connected to the base 3 with the metal roof material 10 interposed.

  When the connection structure using the pedestal 3 as described above is used, the distance between the connection members can be shortened as compared with the case where the solar cell panel 2 and the roof base 30 are directly connected. For this reason, even if the solar cell panel 2 vibrates due to an external force such as a wind force or an earthquake, the vibration at the connection portion is less likely to be amplified than when the distance between the connection members is long. As a result, the solar cell panel 2 Therefore, the positional deviation is less likely to occur, and the installation state is stabilized. Furthermore, since the pedestal 3 is firmly fixed to the roof base 30 and arranged, it is difficult to give a large vibration to the solar cell panel 2. Moreover, when installing the solar cell panel 2 in the metal roof material 10, since the connector 5 should just be driven in toward the base 3 immediately under, the possibility that the connector 5 will be diagonally inserted becomes small. Therefore, the solar cell panel 2 is more firmly fixed, and the connection is easily performed, so that the workability is excellent.

  Furthermore, since the base 3 is provided on the lower side of the metal roof material 10, even when a heavy object such as the solar battery panel 2 is placed, the metal roof material 10 is not easily bent or distorted. Even if the external force is applied, vibration to the roofed article 20 can be suppressed.

  The connector 5 is preferably not inserted into the roof base 30. That is, it is preferable that the connector distal end portion 5 a that is the distal end on the insertion side of the connector 5 does not reach the roof base 30. If the connector 5 is inserted into the roof base 30, for example, if rainwater or the like has entered the inside of the base 3a (that is, the space between the base 3 and the roof base 30), There is a risk that rainwater will leak through the connector 5 to the indoor side. However, when the connector 5 is not inserted in the roof base 30, it becomes easy to prevent such a water leak to the indoor side, and can improve waterproofness. In addition, although the fixing tool 25 currently inserted in the support part 3b has inserted the roof base 30, in this case, since the support part 2 and the roof base 30 are closely_contact | adhered, rain water to this insertion part The intrusion of etc. is difficult to occur.

  FIG. 5B shows an example of the eaves of the roof, and particularly shows an example in the case where a Japanese tile is used as the roof tile 1. As in this embodiment, the pier 35 is fixed to the upper surface of the roof base 30 on which the metal roofing material 10 is not laid, and the protrusions formed at the lower part of the roof tile 1 as conventionally done. It is also possible to hook the roof tile 1 by hooking it on the pier 35. In this case, it is possible to suppress the roof tile 1 from shifting. Note that, for example, when the metal tile as described in FIG. 3A is used as the roof tile 1, it is not necessary to provide the pier 35, and it can be directly installed on the roof base 30. Moreover, the eaves tip part of the eaves tip of the roof base | substrate 30 may be provided with the eaves tip member 36 comprised with a well-known nose cover and a penetration board, and also in order to stabilize the state of the laying of a tile in this top May be provided with a roof tile 33 (eave pier). In addition, although illustration is abbreviate | omitted, it does not restrict | limit especially about construction on the ridge side, What is necessary is just to construct to a well-known structure.

  FIG. 6 shows another form of storing the periphery of the roofed article 20. In this embodiment, sleeve tiles 18 and 19 are laid as the roof tile 1 on the upper surface of the roof base 30 around the roofed article 20 and on which the metal roof material 10 is not laid. In this embodiment, the left sleeve tile (sleeve tile 18) and the right sleeve tile (sleeve tile 19) are wound along the side edge of the roofed article 20. The sleeve tile 18 is wound so that the sleeve drooping portion 18 a is disposed on the metal roof material 10 side, and the sleeve tile 19 is a through plate 38 having the sleeve drooping portion 19 b provided on the side edge of the roof base 30. It is struck so that it may protrude outward. Further, a pier 35 (vertical pier) can be fixedly provided on the roof base 30, and sleeve tiles 18, 19 are placed on one side of the pier 35 along the inner sides of the sleeve hanging portions 18 a, 19 b. Can be ugly.

  By arranging the periphery of the roof attachment 20 as described above, the design of the roof itself can be further improved, and a natural finished roof can be provided. The sleeve tiles 18 and 19 may be made of metal or may be made of an inorganic material such as cement.

  In order to construct the roof having the installation structure of the roof attachment according to the present invention, for example, the following method can be used.

  As shown in FIG. 7, when the pedestal 3 is provided, the pedestal 3 is first fixed at a predetermined position of the roof base 30. Specifically, the pedestals 3 are sequentially arranged and fixed at a predetermined interval in a direction orthogonal to the eave building direction, and further, the pedestals 3 are sequentially arranged and fixed from each pedestal 3 at a predetermined interval in the eave building direction. The pedestals 3 are arranged in a grid pattern on the roof base 30. The position for fixing the pedestal 3 may be determined in advance so that the pedestal 3 is positioned below the roofed structure 20 when the size of the roofed structure 20 to be installed is taken into consideration. . Further, when the base 3 is fixed, as shown in FIG. 7A, a fixing tool 6 such as a screw may be driven into the pair of support portions 3b.

  Next, as shown in FIG. 7B, the metal roofing material 10 is laid so as to cover the pedestal 3 with the ridges 11, that is, so that the ridges 11 and the pedestal 3 face each other vertically. Of the plurality of ridges 11, there may be a ridge 11 that does not cover the pedestal 3. In laying the metal roof material 10, in the adjacent metal roof material 10, the ridge portion 11 of one metal roof material 10 and the ridge portion of the other metal roof material 10 may be overlapped vertically. Preferably, in this case, the metal roof material 10 is stably laid on the roof base 30. In FIG.7 (b), although the protruding item | line part 11 in the most side end of the one metal roof material 10 and the protruding item | line part 11 in the most side end of the other metal roof material 10 are piled up mutually, It is not limited to this. That is, by adjusting the overlapping dimension of the metal roof material 10, the plurality of ridge portions 11 of one metal roof material 10 are laid so as to overlap the plurality of ridge portions 11 of the other metal roof material 10, respectively. You may let them. Further, in order to facilitate the mutual overlapping of the metal roof materials 10, the width of the ridges 11 of the lower metal roof material 10 is the width of the ridges 11 of the upper metal roof material 10. It is preferable that the length is shorter than that.

  Further, since the pedestal 3 shown in FIG. 7 (a) has the projection 3c formed on the top surface of the pedestal 3a, the metal roofing material 10 is laid after the metal roofing material 10 is laid as described above. When pressed to the roof base 30 side, the shape of the protrusion 3 c is transferred to the ridge 11. And since the installation position of the pedestal 3 on the lower side of the metal roofing material 10 can be visually recognized by using the transfer pattern of the projection 3c as a mark, positioning of the solar cell panel 20 to be installed after this becomes easy. .

  On the metal roofing material 10 laid as described above, the roofed article 20 such as the solar battery panel 2 is placed and fixed. In the case where the roof attachment 20 is the solar battery panel 2 and is composed of a plurality of panel units, each panel unit is moved from the eave side (under water) to the ridge side (over water). Connect each panel unit while installing them sequentially. Moreover, when fixing the solar cell panel 2 using the supporting member 25 like the form of Fig.5 (a), it can construct as follows.

  First, the panel unit is arranged at the position closest to the eaves side of the installation area of the solar cell panel 2, and the support member 25 is attached to the eaves side front end of the panel unit. At this time, one of the pair of engaging pieces 25a of the support member 25 is hooked and engaged with the engaged piece 2a formed on the frame of the panel unit, and the connector 5 is driven into the fixing portion 25b. Then, the ridge portion 11 and the top surface of the base portion 3a are penetrated. In addition, since the shape of the protrusion part 3c of the base 3 is transcribe | transferred to the protruding item | line part 11 of the metal roof material 10 as mentioned above, the arrangement position of the solar cell panel 2 and the supporting member 25 is made into this as a mark. Can be determined.

  After fixing one end of the panel unit as described above, one of the engagement pieces 25a of the other support member 25 is connected to the other end (ridge side) of the panel unit to the engaged piece 2a of the panel unit. In the same manner, the coupling 5 is driven into the fixing portion 25b in the same manner as described above. Next, a panel unit is prepared separately and arranged on the ridge side of the existing panel unit, and is similarly hooked and engaged with the other engagement piece 25a of the support member 25 engaged with the existing panel unit. .

  By installing the panel unit from the eave side to the ridge side in the same procedure as described above, the solar cell panel 2 is fixed to the metal roof material 10 and connected to the pedestal 3. Further, if necessary, peripheral members such as the above-described cover member 32 and the pier 35 may be provided in advance. In addition, although the solar cell panel 2 was demonstrated here as an example, of course, it is possible to connect with the pedestal 3 also with the roof attachment 20 other than the solar cell panel 2, and it is made to connect suitably according to the structure. You can do it.

  Then, the roof tile 1 is placed around the roofed article 20 on the roof base 30 on which the metal roofing material 10 (non-installation region) or the metal roofing material 10 is not laid, and the fixture 6 By fixing the roof tile 1, it is possible to form a roof having the installation structure of the roof attachment according to the present invention.
