  FIG. 8 is a cross-sectional view showing a conventional roof fixing device attached to a base material through a hole formed in a tile material. The fixing device 111 includes a base 114 fixed to the base material 113 using fixing means such as a bolt 112, a support 115 attached to the base 114 with screws or bolts, and an attachment member such as a rail above the support 115. And a movable portion 119 that covers the hole 118 formed in the roof tile 117 and is movable relative to the support column 115. The movable portion 119 includes a cover portion 119a that covers the hole 118 formed in the roof tile 117, and a guide portion 119b that extends upward from the cover portion 119a and surrounds the outer peripheral surface of the support column 115. The caulking material 120 is filled between the movable portion 119 and the tile material 117, so that rainwater or the like does not enter the roof inside (the base material 113 side) from the hole 118 formed in the tile material 117. ing. In this fixing device 111, even if a load acts on the upper support portion 116 due to the installation of the solar cell module or the like, the load is supported by the base material 113 via the support column 115 and the base 114. The load does not act on the movable portion 119 that can move relative to the support column 115. Thereby, since it can prevent that external force is added to the waterproofing process part (caulking material 120) between the roof tile 117 and the movable part 119, waterproofness can be improved.

  However, in the fixing device having the above-described configuration, the cover portion is attached to the tile material via the caulking material in order to prevent water from entering below the tile material. Exposure to intense solar radiation will cause severe deterioration over time, and there is a risk that coking will deteriorate early due to the solar radiation. When caulking deteriorates, rainwater can easily enter from between the cover portion and the roof tile. In addition, the guide part covers the middle part of the strut protruding from the cover part, but it is unclear how high the middle part can be covered to prevent rainwater from entering. When rainwater of an amount exceeding the height flows on the surface of the tile material, it is considered that rainwater also enters the lower side of the tile material. Moreover, in order to achieve the said structure, it is possible that not only the shape of a movable part will be complicated but attachment will also become difficult.

  Therefore, the present invention primarily prevents rainwater from entering below the roof tile, and even if rainwater enters below the roof tile, the rainwater enters below the base material below the roof tile.

The cover body is made of a waterproof resin material such as vinyl chloride, a metal member coated with a rust preventive paint, or a rust preventive aluminum or steel material.

 Next, a construction procedure for installing the roof fixing device according to the first embodiment on the roof of the house will be described. First, the hole 11 is formed in the tile material 10 disposed on the base material 4 using a drill or the like. Next, a unit composed of the base 5 and the column 6 is inserted through the hole 11, and the base 5 is fastened to the base material 4 using fastening means such as bolts and nuts. At that time, as shown in FIG. 4, in order to improve the water tightness at the contact surface between the lower surface of the base 5 and the surface portion of the base material 4, at least in the region where these contact surfaces are formed, It is preferable that the butyl tape 22 is stretched as the packing member. Next, the bolt (support member) 9 is inserted into the through hole 6 c of the support column 6. Then, the bolt 9 is inserted into the through hole 7 c formed in the cover body 7, and the cover body 7 is installed on the upper wall portion 6 b of the support 6 so as to enclose the support 6. Next, the nut 13 is screwed onto the bolt 9 and then the nut 13 is fastened toward the surface portion of the cover body 7, whereby the upper surface of the upper wall portion 6 b of the column 6 and the upper cover portion 7 b of the cover body 7 are Make contact with the lower surface.

The cover body 7 is attached to the support column 6 with a gap provided between the base material 4 and the cover body 7. It is attached.

 Next, the sealing part 12 is formed by interposing a caulking material, for example, between the side cover part 7b of the cover body 7 and the peripheral part of the hole part 11 formed in the roof tile 10. Further, in order to fix the attachment member 8 for installing the roof installation body on the roof, the nut 14 is fastened with the bolt 9 inserted through the through hole formed in the attachment member 8. Thereby, the attachment member 8 is fixed to the base material 4 via the support member 9, the support column 6 and the base 5.

 As described above, according to this embodiment, the roof tiles are formed through the holes 11 formed in any roof tile 10 formed by laying a plurality of roof tiles 10 on the base material 4. The roof fixing device 1 that is introduced to the lower side of the material 10 and is fixed to the base material 4 and supports the roof installation body above the tile material 10 is fastened to the base material 4 so as to be watertight to the base material 4. A plurality of bases 5 to be fastened; struts 6 connected to the bases 5 and extending upward from the bases 5; support members 9 extending upward from the tops of the struts 6 to support the roof installation body; And a cover body 7 having a through hole 7c through which the support member 9 is inserted. The cover body 7 is provided with a gap between the base material 4 and the cover body 7. It is attached to the column 6. In the roof fixing device 1, the cover body 7 temporarily prevents the rainwater from entering below the roof tile 10, and the base 5 is watertight to the base material 4 even when rainwater enters the cover body 7. Therefore, the rainwater has a double rainwater intrusion function that can reliably prevent the rainwater from entering below the base material 4 below the roof tile 10. As shown in FIG. 5, even when rainwater 31 further enters the cover body 7, the rainwater 31 follows the gradient of the base material 4 from the gap 21 between the lower end portion of the cover body 7 and the base material 4. As a result, it flows out of the cover body 7 and rain water is prevented from accumulating in the cover body 7.

  Further, by providing a packing member such as butyl tape between the base 5 and the base material 4, the watertightness between the base 5 and the base material 4 can be further enhanced. Even when rainwater enters the cover body 7, the rainwater can be more reliably prevented from entering below the base material 4 below the roof tile 10, so that it has a simple structure and is reliable. A high roof fixing device can be provided.

 Further, the cover body 7 is arranged so that the height of the side cover portion 7 a of the cover body 7 is larger than the maximum distance from the surface portion of the base material 4 to the peripheral edge portion of the hole portion 11 formed in the roof tile 10. Since the upper cover portion 7b of the cover body 7 is positioned above the surface portion of the tile material 10, the side cover portion 7a protruding upward from the surface portion of the tile material 10 is formed. The line of intersection with the surface portion of the roof tile 10 has an arc shape, and a smooth drainage path having a downward slope in the direction from the roof ridge side to the eaves side (water gradient direction) of the side cover portion 7a. Since it comprises, the rain water etc. which fall on the tile material 10 in the ridge side rather than the cover body 7 will be smoothly drained along the outer peripheral surface of the side cover part 7a. Thereby, it is possible to prevent rainwater from staying around the cover body 7 on the roof tile 10.

 In addition, since the cover body 7 is formed so that the side cover portion 7a of the cover body 7 has the same height over the entire circumference and the upper cover portion 7b is flat, the upper cover of the cover body 7 The cover body 7 can be installed so that the portion 7 b is parallel to the surface portion of the base material 4. This makes it possible to clearly grasp the inclination of the base material 4 having an inclination different from that of the tile material 10 from the outside of the tile material 10, and simplifies the construction in the installation of the roof fixing device and the installation of the roof installation body. The construction state can be verified. In addition, the inclination of the roof has various inclination angles depending on the building, but since the height of the side cover portion of the cover body is the same over the entire circumference, the cover body on any roof Even if is installed, the inclination angle of the upper cover body can be matched with the inclination angle of the roof. In addition, the height of the side cover portion of the cover body is the same over the entire circumference, and the through hole is formed in the central portion of the upper cover portion, so the direction of the cover body is anisotropic. The cover body can be attached to the support column in any orientation.

  In order to attach the cover body to the upper wall portion of the column in a state where a gap is provided between the cover body and the base material, various configurations can be adopted. As one configuration, the cover body is formed so as to include the base and the support column, and the cover body is attached to the support column with a gap provided between the base member and the base material. As an example, referring again to FIGS. 2 and 3, the diameter of the inner surface of the side cover portion 7 a of the cover body 7 is larger than the total length and the entire width of the base 5, and the side cover portion 7 a of the cover body 7. If the height from the lower end of the upper cover portion 7b to the back surface of the upper cover portion 7b is slightly smaller than the height from the bottom surface of the base 5 to the upper surface of the upper wall portion 6b of the support column 6, 7 can be attached to the upper wall portion of the support column 6 in a state where the base 5 and the support column 6 are enclosed and a gap is provided between the base member 4 and the base material 4.

  As another configuration in which the cover body is attached to the upper wall portion of the support with a gap between the base material and the base body, the cover body is placed on the base and a part of the base is part of the cover body. It can be set as the form which protrudes from the lower end. As an example, FIG. 6 shows a case where the entire length of the base 5 is larger than the diameter of the inner surface of the cylindrical side cover portion 7a and the width of the base 5 is smaller than the diameter of the inner surface of the side cover portion 7a. It is a perspective view which shows the fixing device 1 for roofs. FIG. 7 is a plan view thereof. Since the overall length of the base 5 is larger than the diameter of the inner surface of the cylindrical side cover portion 7a and the width of the base 5 is smaller than the diameter of the inner surface of the side cover portion 7a, a part of the base is It protrudes from the lower end of the cover body. The height from the lower end portion of the side cover portion 7a to the back surface of the upper cover portion 7b is substantially equal to the height from the upper surface of the base 5 to the upper surface of the upper wall portion 6b of the column 6. Accordingly, in the cover body 7, a part of the lower end portion of the side cover portion 7a is in contact with the upper surface of the base 5, but the portion not in contact with the upper surface of the base 5 at the lower end portion of the side cover portion 7a is the base. It is in a state of floating with a gap 21 from the base material 4 by the thickness of 5. Thereby, the gap 21 is formed between the cover body 7 and the base material 4 just by inserting the support member 9 into the through hole 7c of the cover body 7, and even when rainwater enters the cover body 7, It is discharged from a gap 21 formed in a portion that does not contact the upper surface of the base 5.

 It should be noted that the roof fixing device described by the above embodiment is not intended to limit the present invention, but is disclosed for the purpose of illustration. The technical scope of the present invention is determined by the description of the scope of claims, and various design changes can be made within the technical scope of the invention described in the scope of claims. For example, the cover body described in the embodiment includes a cylindrical side cover part and an upper cover part formed so as to cover the inside of the side cover part. For example, a cover body having, for example, a dome shape, which is formed so as to include the support column (and the base) can also be used.
