Description

  The present invention relates to an attachment device and an attachment method for attaching a mount for installing a rooftop equipment such as a solar cell module or a solar water heater to a tiled roof.

  In recent years, homes that have installed solar cell modules on the rooftop and introduced solar power generation systems that use solar power to generate power have become widespread, and are widely used not only in newly built homes but also in existing homes. Has been introduced.

  Various methods have been proposed for the installation of solar cell modules on the roof. For houses with tile roofs, a stand is attached on the tile roof, and the solar cell module is installed on the stand. There are many. In this case, if the gantry is directly supported by the roof tile, the load of the gantry and the solar cell module is applied to the roof tile, and the roof tile is likely to be chipped or cracked.

  Therefore, special tiles are installed together with general tiles on the roof foundation surface, and the support is fixed on the roof foundation surface so as to penetrate the special tiles, and the support is supported by this support body. Thus, there has been proposed an attachment device that eliminates a load load on general roof tiles and dedicated roof tiles (see, for example, Patent Document 1). In an existing house, a part of general roof tiles installed on the roof base surface is removed, and dedicated roof tiles and supports are provided at the removed locations.

Japanese Patent No. 4112405

  In the mounting apparatus described in Patent Document 1, the metal fittings that form the base of the support are formed in an inverted U shape having a pair of side surfaces and an upper surface, and the pair of side surfaces are made of tile roofs. It is erected on the roof base surface so as to be along the inclination direction. In this case, the support bracket can sufficiently resist the external force in the tilted direction of the tile roof, but the strength against the external force in the transverse direction perpendicular to the tilted direction of the tiled roof is not sufficient. There wasn't. For this reason, in addition to the load on the gantry and the solar cell module, if a further load is applied due to an earthquake, strong wind, snow accumulation, or the like, there is a possibility that deformation or buckling occurs in the metal fitting of the support.

  In addition, since the support metal fittings are erected on the roof foundation surface through the dedicated tile, at least the thickness of the dedicated tile and the gap dimension from the bottom surface of the dedicated tile to the roof foundation surface are added. It has a height greater than its dimensions. Therefore, as a fixing screw for fixing such a metal fitting to the roof base surface, a screw having a long length from the screw head to the tip is used. The comparatively long range of the intermediate part between the front-end | tips is the state exposed without being screwed in a roof basement surface. For this reason, the fixing screw also has a problem that deformation and buckling are likely to occur.

  That is, in the mounting device described in the above-mentioned Patent Document 1, although the base is not supported by the roof tile, chipping and cracking of the roof can be eliminated, but the mounting strength of the base is still lacking in reliability. There was room for.

  Accordingly, the present invention provides an attachment device and an attachment method capable of solving the above-described problems and attaching a pedestal for installing a rooftop equipment such as a solar cell module firmly and stably to a tiled roof. Objective.

  The attachment device 1 of the present invention is for attaching a pedestal 55 on which a rooftop equipment 50 is installed to a tile roof, and is a dedicated tile 2 installed together with a general tile 41 on the roof base surface 40 of the tile roof. And the support 3 that supports the gantry 55, and the support 3 is erected on the roof base surface 40 in a state of penetrating the dedicated tile 2 provided on the roof base surface 40.

  The tubular material 10 is provided with a plurality of screw guide portions 11 for inserting the fixing screws 30 from the upper end portion to the lower end portion thereof. Moreover, the said cylindrical material 10 is formed in the cross-sectional hexagon shape, and the said screw guide part 11 is provided in the inner peripheral surface side of the corner | angular part. Further, the tubular material 10 is provided with a reinforcing partition wall 12 along the inclined direction of the tile roof, straddling between the opposing portions of the inner peripheral surface thereof.

Furthermore, the dedicated roof tile 2 is made of the same ceramic as the general roof tile 41.

  The mounting method of the present invention is a method for mounting the mount 55 to a tile roof using the mounting device 1 described above, and the dedicated tile 2 is installed together with the general tile 41 on the roof base surface 40. The tubular material 10 is erected on the roof base surface 40 in a state of penetrating the dedicated tile 2, and the upper end portion of the tubular material 10 is covered with the upper surface opening 10a of the tubular material 10 at the upper end portion. The plurality of fixing screws 30 that are covered with the cover material 20, place the frame 55 on the cover material 20, pass through the frame 55 and the cover material 20, and are inserted into the cylindrical material 10. The base 55 is attached to the tile roof by being screwed into the roof base surface 40.

  When the mounting device of this invention is used to mount the gantry to the roof tile, and the rooftop equipment is installed on the gantry, the load of the gantry and the rooftop equipment is applied to the support. In addition, it is possible to eliminate the load load on the roof tiles and the special roof tiles, and it is possible to prevent damage to these general roof tiles and the special roof tiles. Moreover, since it is the cylindrical material that constitutes the base portion of the support, it can sufficiently resist external forces in the tilting direction and crossing direction of the tile roof and other directions, and the gantry and rooftop Even if an additional load is applied due to an earthquake, a strong wind, snow, or the like in addition to the load on the equipment, it is possible to prevent the tubular material from being deformed or buckled. Thereby, a mount can be attached firmly and stably. In addition, by increasing the mounting strength with the tubular material, it is possible to reduce the size of the support and to reduce the manufacturing cost of the mounting device.

  In addition, by screwing the fixing screw into the roof base surface while being inserted into the screw guide portion of the cylindrical material, the intermediate portion of the fixing screw that is not screwed into the roof base surface is protected by the screw guide portion, and due to external force The deformation and buckling of the fixing screw can be made difficult to occur, and the mount can be attached firmly and stably.

  Furthermore, by providing the screw guide portion on the inner peripheral surface side of the strong corner portion in the hexagonal cross-sectional cylindrical material, the intermediate portion of the fixing screw can be more reliably protected. Furthermore, by providing a reinforcing partition on the tubular material, deformation and buckling of the tubular material can be further prevented.

This special roof tile 2 is made of the same earthenware as the general roof tile 41, and has the same shape as the general roof tile 41 except for the through holes 4 and the frame-like protrusions 5, so that there is no sense of incongruity in appearance. It can be installed together with the general roof tile 41.

  As shown in FIGS. 2 to 4, the support 3 passes through the reinforcing plate 6 on the roof base surface 40 in a state of passing through the through holes 4 of the dedicated tile 2 provided on the roof base surface 40. The tubular member 10 that is erected and the cover member 20 that is placed on the upper end portion of the tubular member 10 so as to cover the upper surface opening 10a of the tubular member 10 and on which the vertical beam 60 of the mount 55 is placed. And a plurality of fixing screws 30.

  The tubular member 10 is an extruded product made of, for example, aluminum having the same cross-sectional shape over the entire length in the axial direction. The cylindrical member 10 includes a plurality of screw guide portions 11 into which fixing screws 30 are inserted so as to be continuous from the upper end portion (upper surface opening 10a) to the lower end portion (lower surface opening 10b), and the tile roof inclination direction. A reinforcing partition wall 12 is formed. Specifically, as shown in FIG. 4, the tubular member 10 is formed, for example, in a hexagonal shape in cross section, and in the inclined direction of the tile roof among the opposing portions of the inner peripheral surface, that is, the six corner portions. The reinforcing partition 12 is formed so as to bisect the internal space of the tubular member 10 across two opposing corner portions, and on the inner peripheral surface side of the remaining four corner portions among the six corner portions, For example, screw guide portions 11 having a C-shaped cross section are formed. Note that the inner diameter of the screw guide portion 11 is slightly larger than the outer diameter of the fixing screw 30.

  As shown in FIG. 3, the tubular member 10 has a lower surface opening 10 b closed by the reinforcing plate 6 in a state where the cylindrical member 10 is erected on the roof base surface 40 via the reinforcing plate 6, and the upper end surface thereof is It protrudes upward from the upper end surface of the frame-like protrusion 5 of the dedicated roof tile 2.

  The cover member 20 includes a rectangular flat surface portion 21 and a frame portion 22 that protrudes downward from the peripheral end portion of the flat plate 21. The flat portion 21 is formed with four screw insertion holes 23 corresponding to the screw guide portions 11 of the tubular member 10.

  As shown in FIG. 3, in the state where the cover member 20 is placed on the upper end portion of the tubular member 10, the flat surface portion 21 does not contact the upper end surface of the frame-shaped protrusion 5 of the dedicated roof tile 2. The frame portion 22 is in contact with only the upper end surface of the tubular member 10 so as to surround the frame-shaped protrusion 5 of the dedicated roof tile 2 from the outside.

  Note that, as shown in FIG. 2, the vertical beam 60 of the pedestal 55 placed on the cover material 20 includes a rail-shaped main body 61 and a pair of flange portions 62 projecting laterally from the main body 61. A plurality of screw insertion holes 63 are formed in the flange portion 62 at equal intervals in the longitudinal direction.

  The fixing screw 30 is used to fix the vertical beam 60 placed on the cover material 20 to the roof base surface 40 together with the cover material 20 and the tubular material 10, and the length from the screw head to the tip is fixed. Long ones are used. 2 to 4, for example, four fixing screws 30 are used for fastening, and these fixing screws 30 are screw insertion holes 23 in which the vertical beam 60 and the cover member 20 are made to coincide with each other. , 63 is inserted into the screw guide portion 11 of the tubular member 10 and is screwed into the roof base surface 40 via the reinforcing plate 6.

  Next, a method for attaching the pedestal 55 to a tile roof in an existing house, for example, using the attachment device 1 having the above configuration will be described. First, as shown in FIG. 5, the general roof tile 41 provided in the vicinity of the installation location of the support 3 is removed, and the reinforcing plate 6 is screwed to the exposed roof base surface 40. Subsequently, as shown in FIG. 6, the special roof tile 2 is installed instead of the general roof tile 41 so as to cover the reinforcing plate 6. In the case of a newly built house, the reinforcing plate 6 is screwed to the roof base surface 40 in advance, and at the same time as the general tile 41 is installed so that the dedicated tile 2 is located at the place where the support 3 is installed. A special roof tile 2 may be installed.

  Subsequently, as shown in FIG. 7, the tubular material 10 is erected on the roof base surface 40 via the reinforcing plate 6 in a state of passing through the through hole 4 of the dedicated tile 2, and the tubular material 10. A cover material 20 is placed on the upper end portion of the tubular material 10 so as to cover the upper surface opening 10a. Then, as shown in FIG. 8, the vertical beam 60 of the pedestal 55 is placed on the cover material 20, and the fixing screws 30 are inserted from above into the screw insertion holes 23, 63 that are aligned with each other, While being inserted into the screw guide portion 11 of the tubular member 10, the roof base surface 40 is screwed through the reinforcing plate 6. Thereby, the vertical beam 60 of the mount 55 is fastened to the roof base surface 40 together with the cover material 20 and the tubular material 10. In this way, the horizontal beam 70 is appropriately attached across the upper surface of the vertical beam 60 attached to the required place of the tile roof. As a result, the gantry 55 is attached to the tile roof via the attachment device 1.

  When the solar cell module 50 is installed on the gantry 55 by attaching the gantry 55 as described above, the loads of the gantry 55 and the solar cell module 50 are applied to the support body 3, The load applied to the special roof tile 2 can be eliminated, and the general roof tile 41 and the dedicated roof tile 2 can be prevented from being damaged.

  Moreover, since it is the tubular member 10 with the reinforcing partition 12 that constitutes the base portion of the support 3, the tile roof has an inclination compared with the conventional inverted U-shaped one. In addition to being able to sufficiently resist the external force in the direction, it can also sufficiently resist the external force in the transverse direction and other directions, in addition to the load of the gantry 55 and the solar cell module 50, the earthquake Even if a further load is applied due to wind, strong wind, snow or the like, deformation or buckling of the tubular member 10 can be made difficult to occur.

  Furthermore, as the fixing screw 30, it is necessary to fasten the relatively tall tubular member 10 penetrating the dedicated roof tile 2 on the roof base surface 40, so that the length from the screw head to the tip is long. A long one is used, and in a fixed state, a relatively long range of an intermediate portion between the screw head and the tip is not screwed into the roof base surface 40 or the reinforcing plate 6. However, the intermediate portion of the fixing screw 30 is inserted into the screw guide portion 11 of the tubular member 10, and the screw guide portion 11 is strong in the tubular member 10 having a hexagonal cross section. Since the intermediate portion is firmly protected by the screw guide portion 11, the fixing screw 30 is not easily deformed or buckled by an external force.

  From these things, the mount 55 can be firmly and stably attached to the tile roof, and the solar cell module 50 can be installed satisfactorily.

  Furthermore, the dedicated roof tile 2 is made of inexpensive ceramics, and the cylindrical member 10 of the support 3 is an extruded product with excellent productivity. Therefore, the manufacturing cost of the mounting device 1 can be reduced. it can.

  The present invention is not limited to the above embodiment, and it is needless to say that many modifications and changes can be made to the above embodiment within the scope of the present invention. For example, the rooftop equipment installed on the gantry is not limited to the solar cell module, but may be a solar water heater or other equipment.
