Description

  The present invention relates to an on-roof installation fixing device for fixing an on-roof installation such as a solar cell module installed on a roof onto a roof structure.

  Applicant of the present application as a fixing device for fixing on-roof installations (for example, solar cell modules, solar water heaters, roof greening bodies) on roof structures such as field boards and rafters. Has a tile body that is formed in substantially the same shape as a roof tile rolled on the roof structure and is mounted on the roof structure, and a support bulge that protrudes upward from the center of the upper surface of the tile body. In addition, a support tile in which an installation on a roof is fixed to a support bulge has been proposed (Patent Document 1).

  However, in the technique of Patent Document 1, since the weight of the installation object on the roof acts on the entire support tile, the support tile is formed of a metal having high strength and rigidity so as to withstand the weight. There was room for improvement in that the cost of the device was high.

  On the other hand, the cover structure that is placed on the roof structure and formed in substantially the same shape as the roof tile and has a rectangular through hole, and the roof structure that is inserted into the through hole of the cover body There has been proposed a fixing device including a support body attached to the body, and an installation object on the roof being fixed to the upper surface of the support body (Patent Document 2). In the technique of Patent Document 2, since the support body to which the installation object on the roof is fixed through the through hole of the cover body is attached to the roof structure, the weight of the installation object on the roof does not act on the cover body. A relatively inexpensive material with low strength and rigidity can be used for the body, and the cost for the fixing device can be suppressed.

  However, in the technique of Patent Document 2, the support on which the installation on the roof is fixed is formed in a U-shape by bending a flat plate member, and the free end side of the two portions extending in parallel is formed. It is mounted on the roof structure with the lower end. For this reason, since the weight of the installation object on the roof is concentrated on the lower ends of the two parts extending in parallel, the weight of the installation object on the roof acts on a narrow area of the roof structure. There is a problem that becomes easily damaged.

  By the way, for example, when the four corners of a flat rooftop installation object are installed on the roof using four support tiles or fixing devices, if the top surface of the roof structure is distorted with respect to the plane, Among the two support tiles and the fixing device, a gap is formed between the one support tile and the fixing device and the installation object on the roof. And, in the state where a gap is formed between the installation object on the roof, there is a possibility that the installation object on the roof cannot be fixed at the part or the installation object on the roof may be damaged by forcibly fixing it. There is. For this reason, it is conceived that a spacer having the same thickness is inserted into the gap between the installation object on the roof and the supporting tile or the fixing device to fix the installation object on the roof. However, when the spacer is used, since the distortion is not uniform on the upper surface of the roof structure, the size of the gap with the installation object on the roof varies depending on the place where the support tile and the fixing device are attached. Accordingly, it is necessary to prepare a plurality of spacers having different thicknesses in advance so that the gaps of various sizes can be dealt with, resulting in a problem of labor and cost for managing the parts.

  Therefore, in view of the above situation, the present invention can disperse the weight of the installation object on the roof over a wide range of the roof structure and can install the installation object on the roof even if the upper surface of the roof structure is distorted. It is an object to provide an on-roof object fixing device.

  In order to solve the above-described problems, the on-roof object fixing device according to the present invention includes a flat plate-like main body mounted on a roof structure, a through-hole penetrating the main body up and down, and the through-hole. A covering tile having a peripheral wall portion extending upward from the peripheral edge of the plate, and a flat plate-like first mounting portion that is attached in contact with the surface of the roof structure on the lower side of the covering tile, And a first fixing member having a rod-shaped first male screw portion that extends upward from the first mounting portion and passes through the through-hole, and the first male screw portion of the first fixing member passes therethrough. A flat plate-like second mounting portion, a second standing wall portion extending upward from the second mounting portion, and a flat plate-like placement extending in parallel with the second mounting portion from the upper end of the second standing wall portion And a slit penetrating up and down the mounting portion, and the mounting portion passes through the through hole and the peripheral wall portion A second fixing member in which the second mounting portion is attached to the first male screw portion so as to protrude further upward, a head having a diameter larger than the slit of the second fixing member, and the head And has a rod-like second male screw portion that passes through the slit and is attached to the mounting portion so that the second male screw portion protrudes upward through the slit from below. A flat male ceiling member formed with a second male screw member and a through-hole through which the second male screw part of the second male screw member passes, and is formed larger than the outer periphery of the peripheral wall portion in plan view. A plate member, and a side plate portion extending downward from the periphery of the top plate portion, and a cover member placed on the placement portion so as to cover the upper end opening of the peripheral wall portion. And the installation object on the roof is on the second male screw portion protruding upward from the cover member. Constant is the "be characterized.

  Here, the “roof structure” is a portion below the roof tile in the building, and can include a base plate, a rafter, and the like. Moreover, the “installed object on the roof” can be exemplified by a solar cell module, a solar water heater, and a green plant on the roof.

  Also, the main body of the covering tile is preferably the same shape as a general roof tile that is sown on the roof structure, and examples of this type of roof tile, J-shaped, F-shaped, S-shaped, Spanish-shaped tiles are given. can do.

  Further, as the “first fixing member”, in addition to the “member including only the first mounting portion and the first male screw portion” and “the first mounting portion and the first male screw portion”, the first mounting portion is moved upward. A member that further includes a first standing wall portion that extends and a shelf portion that extends in parallel with the first mounting portion from the upper end of the first standing wall portion, and the first male screw portion extends upward from the shelf portion. "," A member in which the first mounting portion and the first male screw portion are separated from each other ".

  Furthermore, as the mounting of the second fixing member to the first male screw portion, “a hole through which the first male screw portion passes in the second mounting portion is a passage hole having a diameter larger than that of the first male screw portion. The first male threaded portion penetrating the screw is attached by screwing a pair of nuts on both sides so as to sandwich the second mounting portion and fastening the pair of nuts. “Attaching by forming a female screw hole screwed into the single male screw part” can be exemplified.

  Further, only one “second standing wall portion” may extend upward from the second mounting portion, or a plurality of “second standing wall portions” may extend upward from the second mounting portion. The “slit” can be exemplified by a long hole-like slit and a slit that divides the placement portion.

  Further, examples of the “second male screw member” include a root bolt, a hexagon bolt, a pan head bolt, and a hexagon socket head bolt, and a male screw member that cannot be rotated by insertion into the slit is desirable.

  According to the roof installation object fixing device of the present invention, the covering tile and the first fixing member are mounted on the roof structure, and the mounting portion passes through the through hole in the first male screw portion of the first fixing member. The second fixing member is attached so as to protrude upward from the peripheral wall portion. In the second fixing member, the second fixing member is attached so that the second male screw portion protrudes upward through the slit of the mounting portion. Then, the cover member is placed on the placement portion at the upper end of the second fixing member so as to cover the peripheral wall portion of the covering tile from above, and the second male screw portion is located above the cover member through the through hole of the cover member. To protrude. Thereafter, the on-roof installation can be installed on the roof by fixing the on-roof installation on the second male screw portion protruding from the cover member.

  Thereby, the weight of the installation object on a roof acts on a roof structure via a 2nd fixing member and a 1st fixing member. And in the 1st fixing member attached to a roof structure, since the flat 1st attachment part is made to contact on the surface with respect to a roof structure, the weight of an installation thing on a roof is on a roof structure. It can be dispersed over a wide range. Therefore, it is possible to reduce the possibility that the roof structure is easily damaged by acting on the roof structure in a concentrated manner in a range where the weight of the installation object on the roof is narrow.

  Moreover, since the 2nd fixing member to which an installation thing on a roof is attached is attached to the 1st male screw part extended upwards of the 1st fixing member attached to a roof structure, the screw action of a 1st male screw part The second fixing member can be freely moved up and down by using. As a result, even when the top surface of the roof structure is distorted with respect to the plane when installing the rooftop installation on the roof using a plurality of on-roof installation fixing devices, the screw action of the first male screw portion By moving the second fixing member up and down, each second fixing member can be adjusted to be on the same plane. Therefore, when the installation on the roof is placed on the upper surface of each second fixing member (cover member), no gap is formed between the second fixing member and the installation object on the roof. It is possible to reduce a problem that an object cannot be fixed, or when an on-roof installation object is fixed, an excessive force acts on the installation object on the roof to cause damage.

  In addition, by moving the second fixing member up and down by the screw action of the first male screw portion, the gap between the second fixing member and the roof structure can be eliminated without using a spacer. There is no need to prepare a plurality of spacers having different thicknesses in advance. Therefore, it is possible to suppress an increase in the number of parts required for the installation of the installation on the roof, and it is possible to suppress an increase in labor and costs related to parts management.

  By the way, in the technique of patent document 2, an attachment hole is formed in the upper piece which has connected the upper ends of the two parts extended in parallel in a support body, and a long screw is screwed in a roof structure body through an attachment hole from the upper side. Thus, the support is attached. For this reason, in the state which attached the support body, the head part of a screw contact | abuts on the upper surface of an upper piece, and it will be in the state which exposed between the upper piece and the roof structure body in the screw. As a result, when rainwater or the like that has entered the roof structure for some reason comes into contact with the exposed part of the screw, the rainwater or the like penetrates the screw from the exposed part of the screw to the lower side of the roof structure. There is a risk of it. On the other hand, in the present invention, as described above, the flat plate-shaped first mounting portion is brought into contact with the surface of the roof structure, and the screw head for mounting on the roof structure is the first mounting. If the space between the head of the screw and the first mounting portion and the space between the first mounting portion and the roof structure are sealed with rubber, silicone resin, etc. It is possible to prevent other parts of the head from being exposed on the roof structure. Therefore, even if rainwater or the like enters the analogy roof structure, it is possible to prevent the rainwater or the like from entering the roof structure.

  Furthermore, since the second male screw part of the second male screw member extends upward through the slit and the second male screw member can be moved along the slit, the first fixing member and the second fixing member Even after mounting on the roof structure, the second male screw member can be moved along the slit. Thereby, even if it does not remove a 1st fixing member from a roof structure, the position of a 2nd external thread part can be changed with respect to a roof structure. Therefore, for example, when fixing a bar-shaped crosspiece member constituting a roof installation object using a plurality (three or more) of roof installation object fixing devices, a right angle to the longitudinal direction of the fixed beam member By attaching a plurality of roof-mounted object fixing devices to the roof structure so that the slits extend in the direction, the second male screw with respect to the fixing line of the crosspiece member (the line on which the crosspiece member should be fixed on the roof) Even if the portion is deviated, the second male screw member can be made to coincide with the fixing line of the crosspiece member by moving the second male screw member along the slit.

  Moreover, since the 2nd fixing member is attached to the 1st male thread part, a 2nd fixing member can be rotated with respect to a 1st male thread part. Thereby, the second fixing member can be directed in a direction suitable for the installation object on the roof to be fixed, and it is possible to cope with various installation objects on the roof without removing the first fixing member from the roof structure. .

  Further, since the second fixing member can be rotated with respect to the first male screw part, for example, the position of the slit (the axis of the second male screw member) is deviated from the axis of the first male screw part. When the second fixing member is cored, the position of the second male screw member can be changed by rotating the second fixing member without removing the first fixing member from the roof structure. It is possible to cope with larger displacement by using it together with the movement by the slit.

  Furthermore, since the installation object on the roof can be fixed via the mounting portion of the second fixing member extended to the upper side through the through-hole of the covering tile, the weight of the installation object on the roof acts on the covering tile. Therefore, a relatively inexpensive material having low strength and rigidity can be used for the covering tile, and the cost for the roof installation fixture can be suppressed.

  Further, in addition to the above-described configuration, the on-roof object fixing device according to the present invention includes: “The first mounting portion has a pair at regular intervals, and the first fixing member has a pair of A pair of first standing wall portions respectively extending upward from the first mounting portion and a shelf portion that connects the upper ends of the pair of first standing wall portions to each other and extends in parallel with the first mounting portion. And the first male screw portion extends from the shelf portion ”.

  By the way, in the 1st external thread part to which a 2nd fixing member is attached, there exists a property which the site | part becomes easy to bend, so that the site | part below a 2nd attachment part becomes long. And in the state where the first male screw portion is easily bent, when a force in the direction along the upper surface of the roof structure acts by hitting wind or rain on the roof installation object attached to the second fixing member The upper side of the first male screw part is likely to vibrate, and the vibration may cause the first male screw part to fatigue and break, or a problem may occur in the installation on the roof.

  On the other hand, in the present invention, in the first fixing member, the first male screw portion extends upward from the shelf portion provided above the first attachment portion by the pair of first standing wall portions. Therefore, compared with the case where the first male screw portion extends directly upward from the flat plate-like first attachment portion, the length of the lower portion of the first male screw portion than the second attachment portion is reduced. Can be shortened. Therefore, since the first male screw portion is relatively difficult to bend, even if a force in a direction along the upper surface of the roof structure acts due to rain or wind hitting the roof installation object, the first male screw It is difficult for the upper side to vibrate from the portion, and it is possible to reduce the possibility that the first male screw portion breaks due to fatigue due to vibration.

  Moreover, in addition to said structure, the roof installation object fixing device which concerns on this invention is "the said 2nd fixed wall part and said mounting part penetrate the said 1st external thread part through said 2nd fixing member. A pair may be provided symmetrically on both sides of the hole, and the slits may extend in a direction perpendicular to the direction in which the pair of second standing wall portions are separated from each other.

  Thereby, since a pair of mounting part is arrange | positioned symmetrically at the both sides of the hole which a 1st external thread part penetrates in a 2nd fixing member, the weight of an installation thing on a roof can pass through a pair of mounting part. The first male screw portion attached to the second attachment portion can be made to act equally. Therefore, even if the weight of the installation object on the roof acts, the first male screw portion is difficult to bend, and the installation object on the roof can be fixed in a favorable state with respect to the roof structure.

  In addition, since the second male screw portion of the second male screw member is protruded upward from the pair of placement portions, respectively, because the installation object on the roof can be received and fixed by the pair of placement portions, Compared with the case where the installation object on the roof is received and fixed by one mounting part (second male screw part), the installation object on the roof can be more firmly fixed. At this time, since the direction in which the slits extend in the pair of placement portions is a direction perpendicular to the direction in which the pair of second standing wall portions are separated from each other, for example, a plurality of on-roof installation object fixing devices are provided. When fixing one bar-shaped crosspiece member by using a pair of second male screw members along the slits, even if the second male screw portion is displaced with respect to the fixed axis of the crosspiece member, The second male screw portion can be aligned with the fixing line of the crosspiece member, and the crosspiece member can be fixed to the pair of placement portions.

  Furthermore, in addition to the above-described configuration, the on-roof object fixing device according to the present invention is “regulation provided on the second fixing member and abutting on the head of the second male screw member from below. It may be characterized by further comprising a portion.

  Here, the “regulating portion” includes “a pair of locking pieces locked to the upper surface of the mounting portion, and a pair of locking pieces connected to each other on the lower side of the mounting portion, A member provided with a receiving piece for abutting the head portion of the two male screw member ”,“ the head portion of the second male screw member extends downward from the lower surface of the mounting portion and extends along the surface of the mounting portion. The “fitting groove that is fitted from the right direction” and “the extending piece extending from the side surface of the second standing wall portion to the lower side of the head of the second male screw member” can be exemplified.

  Thereby, it can prevent that a 2nd male screw member falls from a mounting part because a control part contacts the head of a 2nd male screw member from the lower side. Therefore, it is not necessary to continue to support the second male screw member so as not to fall when attaching the roof installation object fixing device to the roof structure or fixing the roof installation object to the second male screw part. Workability at the time of installing the installation object on the roof is improved.

  Furthermore, the on-roof installation fixing device according to the present invention includes a flat plate-like main body mounted on the roof structure, a through-hole penetrating the main body up and down, and extending upward from a peripheral edge of the through-hole. A covering tile having a peripheral wall portion, a flat plate-like first mounting portion attached on the roof structure in contact with the surface below the covering tile, and the first mounting portion. A first fixing member that extends upward and has a rod-shaped first male screw portion that passes through the through hole, and the first male screw portion of the first fixing member passes through the first fixing member. A flat plate-like second attachment portion attached to the male screw portion, a second standing wall portion extending upward from the second attachment portion to the upper side of the peripheral wall portion through the through hole, the second standing wall A flat plate-like mounting portion extending in parallel with the second mounting portion from the upper end of the mounting portion, and a slot penetrating vertically through the mounting portion. A second fixing member having a lid, a head having a diameter larger than the slit of the second fixing member and attached to the lower side of the mounting portion, and the slit from the head A second male screw member having a rod-like second male screw portion that protrudes upward from the mounting portion through the side, and the second male screw portion of the second male screw member passes through A flat top plate portion that is formed larger than the outer periphery of the peripheral wall portion in a plan view, and a peripheral edge of the top plate portion. A cover member having a side plate portion extending to a lower side than an upper end of the peripheral wall portion, and an installation object on the roof is formed on the second male screw portion protruding upward from the cover member. It is characterized by being “fixed”. Thereby, there can exist an effect similar to the above.

  Thus, according to the present invention, the weight of the on-roof installation can be distributed over a wide range of the roof structure, and the roof installation can be installed even if the upper surface of the roof structure is distorted. An upper installation fixing device can be provided.

Thereafter, a plain washer 20 and a spring washer 21 are sequentially fitted into the first male threaded portion 12g extending through the second mounting portion 13a, and further, the upper nut 19 is screwed to attach the upper nut 19 to the first male screw portion 12g. Tighten.

  At this time, the pair of mounting portions 13d (second standing wall portion 13c) of the second fixing member 13 is separated from the direction in which the pair of first mounting portions 12a of the first fixing member 12 are separated from each other. The second fixing member 13 is attached to the first male threaded portion 12g so that the direction in which it is located is a right angle. Further, when the height from the lower surface of the first mounting portion 12a of the first fixing member 12 to the upper surface of the mounting portion 13d of the second fixing member 13 is mounted on the roof structure 2, the covering tile 11 The second fixing member 13 is attached to the first male screw member 12g so as to be above the peripheral wall portion 11c.

  Further, in the second fixing member 13, the second male screw portion 14b of the second male screw member 14 is inserted from below into the slit 13e penetrating each of the pair of mounting portions 13d, and the mounting portion 13d The head 14a is brought into contact with the lower surface. As a result, the root angle portion 14c of the second male screw member 14 is positioned in the slit 13e, and the second male screw member 14 is movable along the slit 13e and rotated by the root angle portion 14c and the slit 13e. It becomes impossible.

  Then, with the head 14a of the second male screw member 14 in contact with the lower surface of the mounting portion 13d, the receiving piece 16b of the regulating member 16 is brought into contact with the lower side of the head 14a, and both ends The locking piece 16a is locked to the upper surface of the mounting portion 13d. At this time, the direction in which the receiving piece 16b extends is matched with the direction in which the slit 13e extends. Accordingly, the downward movement of the second male screw member 14 is restricted, and the second male screw member 14 is attached to the second fixing member 13.

  When the covering tile 11 is attached to the roof structure 2, the first fixing member 12 to which the second fixing member 13 is attached is attached to the roof structure 2. Specifically, the covering attached to the roof structure 2 with the first fixing member 12 facing so that the direction in which the pair of first attachment portions 12a are separated from each other is perpendicular to the flow direction of the roof. The pair of attachment portions 12 a are brought into contact with the roof structure 2 by being inserted into the through-hole 11 b of the roof tile 11 from above. Thereafter, the screw 4 is screwed into the roof structure 2 from the upper side through the attachment hole 12b, and the head 4a is brought into contact with the upper surface of the first attachment portion 12a, whereby the first fixing member 12 is attached to the roof structure 2. It is done.

  When the first fixing member 12 is attached, a sheet-like seal member 22 formed of butyl rubber or the like is inserted between the pair of attachment portions 12a and the roof structure 2. The seal member 22 may be pasted on the lower surface of the first mounting portion 12a in advance. The seal member 22 can prevent rainwater or the like from entering the inside or the lower side of the roof structure 2 through the screw 4.

  By attaching the first fixing member 12 to the roof structure 2, the pair of mounting portions 13 d of the second fixing member 13 protrudes above the peripheral wall portion 11 c through the through-hole 11 b of the covering tile 11. It becomes a state. The second male screw portion 14b of the second male screw member 14 extending upward from the pair of mounting portions 13d of the second fixing member 13 has a flat plate shape with a hole formed of rubber. The waterproof members 23 are fitted respectively. Then, the cover member 15 is approached from the upper side of the second male screw portion 14b, the second male screw portion 14b is passed from the lower side through the through hole 15b, and the top plate portion 15a is placed on the placement portion 13d. Thus, the upper side of the through-hole 11b of the covering tile 11 is covered with the cover member 15, and the two second male screw portions 14b protrude upward from the top plate portion 15a of the cover member 15. It becomes.

  Further, by covering the cover member 15 from the upper side of the peripheral wall portion 11c, the waterproof material 17 attached to the inside of the cover member 15 is pushed and deformed by the upper end of the peripheral wall portion 11c, and at the same time, the peripheral wall portion 11c and the side plate portion. 15c, or between the upper end of the peripheral wall portion 11c and the top plate portion 15a, and is sealed in a watertight manner. Thereby, it is possible to prevent rainwater or the like from entering the through-hole 11b (on the roof structure 2) through the space between the peripheral wall portion 11b of the covering tile 11 and the cover member 15.

  And the crosspiece member 1a which comprises the installation object 1 on a roof is fixed with respect to a pair of 2nd external thread part 14b which protrudes upwards from the cover member 15. FIG. Specifically, the crosspiece member 1a is placed on the top plate portion 15a of the cover member 15 by inserting the second male screw portion 14b into a fixing hole (not shown) formed in the bottom surface of the crosspiece member 1a. To do. Then, the crosspiece member 1a can be fixed on the cover member 15 by screwing the nut 5 into the second male screw portion 14b penetrating the fixing hole of the crosspiece member 1a and tightening. Accordingly, the on-roof installation 1 is installed on the roof structure 2 by the fixing device 10.

  When the crosspiece member 1a is fixed, if the second male screw portion 14b is displaced from the fixing line of the crosspiece member 1a (the line on which the crosspiece member 1a is to be fixed on the roof), the second male screw is displaced. By moving the portion 14b (the male screw member 14) along the slit 13e of the second fixing member 13, the second male screw portion 14b can be aligned with the fixed axis.

  In addition, when changing the height at which the crosspiece member 1a is fixed to the upper surface of the roof structure 2, the upper nut 19 attaching the second fixing member 13 to the first male screw portion 12g is loosened, Alternatively, the lower nut 18 is moved up and down by the screw action of the first male screw portion 12g with the upper nut 19 removed from the first male screw portion 12g. Then, the second fixing member 13 is attached to the first male screw portion 12g in a state where the lower nut 18 is moved to a position where the second fixing member 13 is at a desired height, whereby the crosspiece member 1a is fixed. Can be changed.

  In the above fixing method, the first fixing member 12 is attached to the roof structure 2 in a state where the second fixing member 13 is attached to the first fixing member 12. After separating the member 13 and attaching the first fixing member 12 to the roof structure 2 first, the second fixing member 13 may be attached to the first male screw portion 12g of the first fixing member 12. .

  Thus, according to the fixing device 10 of the present embodiment, the first fixing member attached on the roof structure 2 in the first fixing member 12 and the second fixing member 13 on which the weight of the installation object 1 on the roof acts. 12, the flat first attachment portion 12 a is attached in contact with the surface of the roof structure 2 so that the weight of the installation object 1 on the roof is distributed over a wide range on the roof structure 2. Can do. Therefore, it is possible to reduce the possibility that the roof structure 2 is easily damaged by acting on the roof structure 2 while the weight of the on-roof installation object 1 is concentrated in a narrow range.

  Moreover, since the 2nd fixing member 13 to which the installation object 1 on a roof is attached to the 1st male screw part 12g of the 1st fixing member 12 attached to the roof structure 2, the screw | thread of the 1st male screw part 12g is attached. The second fixing member 13 can be freely moved up and down by the action. Thereby, for example, when one crosspiece 1a is fixed using the three fixing devices 10, even if the upper surface of the roof structure 2 is distorted with respect to the plane, the first male screw portion 12g causes the first action. By moving the two fixing members 13 up and down, the second fixing members 13 can be adjusted to be on the same plane. Accordingly, no gap is formed between the second fixing member 13 and the crosspiece member 1a when the crosspiece member 1a is placed on the upper surface of each second fixing member 13 (cover member 15). It is possible to reduce problems that the member 1a cannot be fixed, or that the member 1a is damaged due to an excessive force acting when fixing the crosspiece member 1a.

  Further, by moving the second fixing member 13 up and down by the screw action of the first male screw portion 12g, the gap between the second fixing member 13 and the crosspiece member 1a can be eliminated without using a spacer. Therefore, it is not necessary to prepare a plurality of spacers having different thicknesses in advance. Therefore, the increase in the number of parts concerning installation of the installation object 1 on a roof can be suppressed, and the increase in the effort and cost concerning parts management can be suppressed.

  Further, since the flat first attachment portion 12a is in contact with the surface on the roof structure 2, by sealing the space between the first attachment portion 12a and the roof structure 2 with the seal member 22, Even if rainwater or the like enters the roof structure 2, it is possible to prevent the rainwater or the like from entering the roof structure 2 through the screws 4.

  Further, since the second male screw member 14 can be moved along the slit 13e of the second fixing member 13, the first fixing member 12 and the second fixing member 13 can be moved even after the first fixing member 12 and the second fixing member 13 are mounted on the roof structure 2. The male screw member 14 can be moved along the slit 13e. Thereby, even if it does not remove the 1st fixing member 12 and the 2nd fixing member 13, the position of the 2nd male screw part 14b is changed with respect to the roof structure 2, and the 2nd male screw part 14b is changed to the crosspiece member 1a. Can be matched to the fixed line.

  Further, since the second fixing member 13 is attached to the first male screw portion 12g, the second fixing member 13 can be rotated with respect to the first male screw portion 12g. Accordingly, the second fixing member 13 can be directed in a direction suitable for the crosspiece 1a of the on-roof installation 1 to be fixed, and various roof tops can be obtained without removing the first fixing member 12 from the roof structure 2. This can correspond to the installation object 1. Specifically, in the present embodiment, an example in which the crosspiece member 1a extending in the flow direction of the roof has been shown, but for example, the second fixing member 13 is rotated 90 degrees with respect to the first male screw portion 12g. By doing so, the crosspiece member 1a extending in the direction perpendicular to the flow direction of the roof can also be fixed.

  Moreover, since the 1st fixing member 12 and the 2nd fixing member 13 to which the installation object 1 on a roof is fixed through the through-hole 11b of the covering tile 11 are attached to the roof structure 2, the weight of the installation object 1 on a roof is the weight. It does not act on the covering tile 11. Thereby, the comparatively cheap material with low intensity | strength and rigidity can be used for the roofing tile 11, and the cost concerning the fixing device 10 can be suppressed.

  Further, in the first fixing member 12, the first male screw portion 12g extends upward from the shelf portion 12d located above the first mounting portion 12a by the first standing wall portion 12c. Compared to the case where the first male screw portion 12g extends directly upward from the first mounting portion 12a having a shape, the first male screw portion 12g is lower than the second mounting portion 13a of the second fixing member 13. The length of the part can be shortened. Accordingly, since the first male screw portion 12g is relatively difficult to bend, even if a force in a direction along the upper surface of the roof structure 2 is applied due to rain or wind hitting the installation object 1 on the roof, It is difficult for the upper side from the single male screw portion 12g to vibrate, and the possibility that the first male screw portion 12g breaks due to fatigue due to vibration can be reduced.

  Further, in the second fixing member 13, since the pair of mounting portions 13d are symmetrically disposed on both sides of the passage hole 13b through which the first male screw portion 12g penetrates, the mounting is performed on the roof via the pair of mounting portions 13d. The weight of the thing 1 can be made to act equally with respect to the 1st external thread part 12g attached to the 2nd attachment part 13a. Therefore, even if the weight of the installation object 1 on the roof acts, the first male screw portion 12g is difficult to bend, and the installation object 1 on the roof can be fixed to the roof structure 2 in a good state.

  In addition, since the second male screw portions 14b are extended upward from the pair of placement portions 13d, the roof installation object 1 can be received and fixed by the pair of placement portions 13d. Compared with the case where the installation object 1 on the roof is received and fixed by the two mounting parts (second male screw parts), the installation object 1 on the roof can be more firmly fixed.

  Further, since the second male screw member 14 can be prevented from dropping from the placement portion 13d by the restricting member 16, when the second fixing member 13 is attached to the roof structure 2, the second male screw portion 14b. When fixing the installation object 1 on the roof, it is not necessary to continue to support the second male screw member 14 so as not to fall, and the workability when installing the installation object 1 on the roof is good.

  Further, since the first fixing member 12 can pass through the through-hole 11 b of the covering tile 11, the first fixing member 12 can be attached to the roof structure 2 after the covering tile 11. Therefore, after attaching the covering tile 11 with the position of the other roof tile 3, the first fixing member 12 is attached to the roof structure 2 from the upper side through the through-hole 11 b, so that the first fixing member 12 is properly connected. It can be easily attached to the attachment position, and the attachment work to the roof structure 2 can be simplified.

  The present invention has been described with reference to the preferred embodiments. However, the present invention is not limited to the above-described embodiments, and various improvements can be made without departing from the scope of the present invention as described below. And design changes are possible.

  For example, in the above embodiment, in the first fixing member 12, the main body member 12A and the first male screw member 12B are integrated by welding or caulking. However, the present invention is not limited to this, and the main body member 12A is not limited thereto. On the other hand, the first male screw member 12B may be removable by screw connection.
