The internal spaces of the washer accommodating portion 320, the washer accommodating portion 321, and the head accommodating portion 322 are in communication with each other.

[0033] (2.4) Construction process A plurality of roof accessory installation devices 100 of this embodiment are arranged on a roof surface 51 and are used to install roof accessories 50 such as solar panels.

[0034] FIG. 3 shows a roof 52 on which the roof accessory installation device 100 is installed. The roof 52 is formed of a metal sandwich panel 520. The roof 52 may be formed of folded plates. The metal sandwich panel 520 is formed by providing a core material 522 between two metal skins 521. As the metal skin 521, a galvanized steel sheet, a painted steel sheet, a Galvalume steel sheet (registered trademark), an SGL (registered trademark) steel sheet, or the like is used. As the core material 522, a resin foam such as isocyanurate foam, polyurethane foam, or phenol foam, or an inorganic fiber material such as rock wool or glass wool is used. In this embodiment, the thickness of the metal skin 521 is preferably 0.25 mm to 1.6 mm, which allows the receiving member 20 to be firmly fixed to the roof 52. The density of the core material 522 is 30 to 60 kg / m 3 When the density of core material 522 is within this range, core material 522 is not too hard, and expansion portion 221 can easily expand.

[0035] The metal sandwich panel 520 has a peak 523. The peak 523 is formed long in the front-rear direction (water flow direction of the roof 52). The peak 523 is formed to have a substantially trapezoidal cross section and has a pair of inclined portions 5231 and a peak 5232. Each inclined portion 5231 is formed so as to slope downward from the left end and the right end of the peak 5232, respectively. The peak 5232 is formed flat. The metal sandwich panel 520 has a plurality of peaks 523, and a valley 524 is formed between adjacent peaks 523. The valley 524 is formed flat, and the left end and the right end of the valley 524 are connected to the lower end of the inclined portion 5231 of the adjacent peak 523. Therefore, the peak 523 protrudes upward from the valley 524.

[0036] The metal sandwich panel 520 is fixed to a building frame such as a main house to form a roof 52. In this case, a roof surface 51 which is the upper surface of the roof 52 is made of a metal sheet material 53. That is, of the two metal skins 521 of the metal sandwich panel 520, the upper metal skin 521 becomes the metal sheet material 53 which constitutes the roof surface 51.

[0037] In the roof accessory installation device 100, first, the fixing member 2 is formed on the roof 52, and then the mounting base 1 is fixed to the roof 52. In forming the fixing member 2, the one-sided bolt 25 is used. In this case, first, the mounting hole 54 into which the one-sided bolt 25 is inserted is formed in the roof 52. The mounting hole 54 is formed in the peak portion 523. The mounting hole 54 penetrates the metal plate material 53 in the up-down direction at the top portion 5232 of the peak portion 523. The mounting hole 54 is formed in the peak portion 523 so as to reach the core material 522.

[0038] Next, as shown in Fig. 4, the lower part of the one-side bolt 25 is inserted into the mounting hole 54. The upper end of the mounting hole 54 opens to the roof surface 51 at the apex 5232, and the one-side bolt 25 is inserted from this opening. The one-side bolt 25 has the tubular member 22 and the fastening member 21 inserted into the mounting hole 54 below the packing 28. In this case, the packing 28 comes into contact with the roof surface 51 around the opening of the mounting hole 54.

[0039] Next, the receiving member 20 is formed from the cylindrical member 22 of the one-side bolt 25. In forming the receiving member 20, the fastening member 21 is rotated relative to the cylindrical member 22 with the lower part of the one-side bolt 25 inserted into the mounting hole 54. At this time, the fastening member 21 is rotated about the axial direction (vertical direction), but the fastening member 21 is rotated while holding the cylindrical member 22 so that it hardly rotates so that the cylindrical member 22 does not rotate together with the fastening member 21. In addition, when the fastening member 21 is rotated, the lower part of the fastening member 21 is fastened to the female thread portion 220 of the cylindrical member 22, and the fastening member 21 is rotated while holding the fastening member 21 so that the fastening member 21 does not move downward relative to the cylindrical member 22 due to this fastening. At this time, the nut portion 26 provided on the fastening member 21 suppresses the downward movement of the fastening member 21. That is, the nut portion 26 is caught on the upper end of the tubular member 22 (the upper end of the washer portion 222) via the washer 27, so that the downward movement of the fastening member 21 is suppressed.

[0040] When the fastening member 21 is rotated as described above, the female thread portion 220 moves upward while the deformation portion 225 is deformed. That is, when the fastening member 21 is rotated, a force that pulls the female thread portion 220 upward is generated by the rotation, and the deformation portion 225 is pushed up from the lower end by this force. Then, the deformation portion 225 is bent so as to spread outward near the center in the vertical direction and deforms into a "L" shape. As a result, the female thread portion 220 moves upward while the center of the deformation portion 225 in the vertical direction deforms in a direction away from the fastening member 21. Note that the core material 522 around the deformation portion 225 is a soft material such as rock wool, so the deformation portion 225 deforms while biting into the core material 522 around it.

[0041] Then, the hook portion 23 is formed by greatly expanding the outer diameter of the expansion portion 221 due to the multiple plastically deformed deformation portions 225. The hook portion 23 is hooked onto the metal plate material 53 inside the metal sandwich panel 520. That is, the hook portion 23 expands to a size larger than the diameter of the mounting hole 54 below the top portion 5232, and is hooked onto the opening edge portion of the mounting hole 54.

[0042] The receiving member 20 can be formed by deforming the cylindrical member 22 as described above. The receiving member 20 is fixed to the roof 52 at the top 5232 by sandwiching the metal plate material 53 at the opening edge of the mounting hole 54 between the washer portion 222 and the hook portion 23. Furthermore, since the packing 28 is in close contact with the periphery of the opening of the mounting hole 54 on the roof surface 51, waterproofing is not impaired. Furthermore, the fastening member 21 is held by the receiving member 20 in a state where it is fastened to the female thread portion 220.

[0043] Next, as shown in Figures 5, 6 and 7, the rack 1 is installed on the roof surface 51. In this case, first, the fastening member 21 and one upper washer 27 are removed from the receiving member 20. To remove the fastening member 21 from the receiving member 20, the fastening member 21 is rotated in the opposite direction to that in which the hook portion 23 was formed. This causes the lower thread portion 292 to rotate relative to the female thread portion 220, and the female thread portion 220 and the lower thread portion 292 can be released from each other. Thereafter, the fastening member 21 is pulled upward from the receiving member 20.

[0044] Next, the pedestal 1 is placed on the mountain portion 523. In this case, one washer 27 is positioned between the upper surface of the washer portion 222 and the lower surface of the bottom portion 15 of the pedestal 1. In addition, the opening of the receiving member 20 on the upper surface of the washer portion 222, the opening of the washer 27, and the hole portion 16 of the pedestal 1 are arranged to be aligned in the vertical direction.

[0045] After this, the fastening member 21 is attached to the receiving member 20 again. In this case, the lower threaded portion 292 and the non-threaded portion 291 of the fastening member 21 are inserted in the order of one washer 27, the hole portion 16, the other washer 27, and the opening of the receiving member 20 on the upper surface of the washer portion 222. Then, the lower threaded portion 292 and the female threaded portion 220 are fastened to tighten the fastening member 21 to the receiving member 20. In this way, the base 15 of the groove portion 13 is pressed from above with the nut portion 26, so that the base 1 can be fixed to the fixing member 2. The base 1 is installed so as to straddle the top portion 5232 of the mountain portion 523. The pair of leg lower portions 101 of the base 1 are each placed on the inclined portion 5231 via the cushion material 102.

[0046] (2.5) Construction process of roof accessories The roof accessory installation device 100 of this embodiment is used to install a roof accessory 50. When the roof accessory 50 is a flat solar panel 501 as shown in Figs. 8, 9, and 10, the peripheral end of the solar panel 501 can be placed on the mounting portion 14 of the rack 1.

[0047] In FIG. 8, solar panels 501 are arranged at the front and rear positions sandwiching the fastening member 21. The solar panel 501 is fixed to the roof accessory installation device 100 by the two-sided clamps 6. The two-sided clamps 6 include a base piece 60, a pair of rising pieces 61, and a pair of clamping pieces 62. The base piece 60 is formed in a flat plate shape, and is provided with a hole (not shown) penetrating in the vertical direction. The pair of rising pieces 61 are formed in a flat plate shape. The pair of rising pieces 61 are provided at the front end and rear end of the base piece 60, respectively, and are formed to protrude upward from the base piece 60. The pair of clamping pieces 62 are formed in a flat plate shape. The pair of clamping pieces 62 are provided at the upper ends of the pair of rising pieces 61, respectively. One clamping piece 62 protrudes forward from the rising piece 61 on the front end side. The other clamping piece 62 protrudes backward from the rising piece 61 on the rear end side.

[0048] Then, the base piece 60 is attached to the upper threaded portion 290 of the fastening member 21 through the hole, the front pressing piece 62 is hooked onto the upper surface of the rear end portion of the front solar panel 501, and the rear pressing piece 62 is hooked onto the upper surface of the rear end portion of the front solar panel 501. Thereafter, the fixing nut 63 is attached to the upper threaded portion 290 of the fastening member 21, and the base piece 60 is pressed down from above with the fixing nut 63, thereby allowing the solar panel 501 to be fixed to the roof accessory installation device 100 by the two side pressing devices 6.

[0049] 9 and 10, the solar panel 501 is disposed on the rear side of the fastening member 21, and the solar panel 501 is fixed to the roof accessory installation device 100 by the one-side clamp 7. The one-side clamp 7 includes a base piece 70, a rising piece 71, a clamping piece 72, and a reinforcing piece 74. The base piece 70 is formed in a flat plate shape, and is provided with a hole (not shown) penetrating in the vertical direction. The rising piece 71 is formed in a flat plate shape. The rising piece 71 is provided at the rear end of the base piece 70, and is formed to protrude upward from the base piece 70. The clamping piece 72 is formed in a flat plate shape. The clamping piece 72 is provided at the upper end of the rising piece 71. The reinforcing piece 74 is formed in a flat plate shape. The reinforcing piece 74 is provided at the front end of the base piece 70, and is formed to protrude downward from the base piece 70.

[0050] Then, base piece 70 is attached to upper threaded portion 290 of fastening member 21 through the hole, and pressing piece 72 is hooked onto the upper surface of the front end portion of solar panel 501 rearward of fastening member 21. Thereafter, fixing nut 73 is attached to upper threaded portion 290 of fastening member 21, and base piece 70 is pressed down from above with fixing nut 73, thereby allowing solar panel 501 to be fixed to roof accessory installation device 100 by one-sided pressing tool 7.

[0052] (2.6) Removal of roof attachments 11 and 12 show the structure after removing the roof attachment 50. To remove the roof attachment 50, the fixing nuts 63, 73 are removed from the fastening members 21, and the two-side clamps 6 and one-side clamps 7 are also removed from the fastening members 21. Thereafter, the solar panel 501 (roof attachment 50) is removed from the frame 1 and removed.

[0053] In the roof accessory installation device 100 of this embodiment, when the roof accessory 50 is removed, the mount 1 and the fastening member 21 are also removed. Therefore, the mount 1 and the fastening member 21 do not remain on the roof surface 51 after removal, and the appearance of the roof 52 is not easily deteriorated. The mount 1 can be removed after the fastening member 21 is removed from the receiving member 20. The fastening member 21 is rotated with respect to the female threaded portion 220 in the opposite direction to that when the hook portion 23 was formed, thereby releasing the fastening between the female threaded portion 220 and the lower threaded portion 292, and then the non-threaded portion 291 and the lower threaded portion 292 of the fastening member 21 are pulled upward from the receiving member 20. As a result, the receiving member 20 and the packing 28 remain on the roof 52.

[0054] Next, the bolt 31, which is the decorative member 3, is inserted into the receiving member 20 from above and fastened to the female thread portion 220. Next, if necessary, the cap 32, which is the decorative member 3, is placed over the head 310 and washer portion 222 of the bolt 31.

The washer 27 is accommodated inside the washer accommodating portion 321. The head 310 is accommodated inside the head accommodating portion 322.

[0055] As described above, the cap 32 does not have to be used. In this case, the head 310 of the bolt 31 is located above the washer portion 222. When the cap 32 is not used, the head 310 of the bolt 31 and the washer portion 222 are not covered by the cap 32 and are exposed. Therefore, it is preferable to use the cap 32 from the viewpoint of waterproofing.

[0056] In this way, with the roof accessory installation device 100 of this embodiment, even after the roof accessory is removed, the washer portion 222 is not exposed on the roof surface 51, and the appearance of the roof 52 is not marred. As shown in Fig. 13, with the roof accessory installation device 100 of this embodiment, after the roof accessory is removed, only the cap 32 of the decorative member 3 (if the cap 32 is not used, the washer portion 222 and the head 310 of the bolt 31) is visible on the roof surface 51, and the appearance of the roof 52 is not marred.

[0057] Furthermore, if the roof attachment 50 is to be installed again after the decorative member 3 has been installed, the decorative member 3 can be removed from the receiving member 20 and the fastening member 21 can be attached to the receiving member 20 to form the fixing member 2, and then the mounting base 1 can be attached and the roof attachment 50 can be installed.
