DETAILED DESCRIPTION OF THE INVENTION

[0012] (Embodiment 1) The following describes an installation structure for a mounting fixture for a functional component according to one embodiment of the present invention, with reference to the drawings. The figures described in the following embodiments are schematic, and the ratios of the sizes and thicknesses of the components in the figures do not necessarily reflect the actual dimensional ratios. The following embodiments and modifications are merely a portion of various embodiments of the present invention. The following embodiments and modifications can be modified in various ways depending on the design, etc., as long as the object of the present invention can be achieved. The configurations of the modifications can also be combined as appropriate.

[0013] 1. Overview The installation structure of the mounting fixture 100 of the functional member S of this embodiment is formed by using the mounting fixture 100 in a roofing structure 200 (see Figure 1). The roofing structure 200 is formed by installing multiple flat roofing materials 10 with parts overlapping in the eaves-ridge direction. The mounting fixture 100 comprises a base material 2 made of a plate-like member with a roughly J-shaped cross section. The base material 2 has a base material main body 20 and a folded portion 21. The base material main body 20 is arranged on a part of the front side of the flat roofing material 10. The folded portion 21 is located at the front end of the base material main body 20 and enables it to embrace the eaves side end of the flat roofing material 10. The folded portion 21 is inserted between the flat roofing material 10 and a flat roofing material 11 one step closer to the eaves than the flat roofing material 10, and is adhesively fixed to at least the flat roofing material 11 one step closer to the eaves.

[0014] With the fixture 100 of this embodiment, the base material 2 can be installed on a roofing structure 200 to which multiple flat roofing materials 10 have been installed. That is, the base material 2 can be installed by inserting the folded portion 21 between the flat roofing material 10 and the flat roofing material 11 on the first eaves side, and adhesively fixing the folded portion 21 to the flat roofing material 10 and the flat roofing material 11 on the first eaves side. Therefore, the fixture 100 can be installed on the roofing structure 200 after the flat roofing materials 10, 11 have been laid, and this fixture 100 can be used to install the functional member S on the roof afterwards.

[0015] 2.Details 1 shows the installation structure of a mounting fixture 100 for a functional member S of this embodiment. A solar panel is used as the functional member S. In addition to solar panels, examples of the functional member S include water heating systems, antennas, and snow guards.

[0016] <Roofing structure> The roofing structure 200 is a roof structure before the mounting fixtures 100 and functional components S are installed. The roofing structure 200 comprises a plurality of flat roofing materials 10 and a roof underlayment 13. The flat roofing materials 10 are plate-shaped roofing materials with flat front and back surfaces. The flat roofing materials 10 can be ceramic roofing materials that are hardened cement products, but they may also be metal roofing materials. The roof underlayment 13 is a base on which the plurality of flat roofing materials 10 are placed. The roof underlayment 13 comprises flat members 130 such as sheathing boards. The flat members 130 have a flat surface. The roof underlayment 13 also comprises a waterproof sheet 131 such as asphalt roofing. The waterproof sheet 131 is applied over the entire surface of the flat members 130.

[0017] Then, the multiple flat plate roofing materials 10 are placed on the surface of the roof underlayment 13 (the surface of the waterproof sheet 131) and fixed to the flat plate members 130 of the roof underlayment 13 with fasteners 14 such as screws. The multiple flat plate roofing materials 10 are installed with a portion overlapping in the eaves-ridge direction. In other words, the multiple flat plate roofing materials 10 are placed side by side in the eaves-ridge direction on the surface of the roof underlayment 13, with adjacent flat plate roofing materials 10 in the eaves-ridge direction being arranged with a portion overlapping. Here, the eaves-ridge direction means the direction in which the roofing structure 200 slopes relative to the horizontal, and is the direction in which an imaginary straight line connecting the eaves and ridge of the roofing structure 200 extends.

[0018] Of the three flat plate roofing materials 10 lined up adjacently in the eaves-ridge direction, the flat plate roofing material 10 closest to the eaves (first from the eaves side) is placed on top of the flat plate roofing material 10 closest to the eaves. The flat plate roofing material 10 closest to the ridge (third from the eaves side) is placed on top of the middle flat plate roofing material 10. Two flat plate roofing materials 10 adjacent in the eaves-ridge direction overlap each other partially (approximately half) in the eaves-ridge direction.

[0019] Furthermore, between two adjacent flat roofing materials 10 in the eaves-ridge direction, there is a step equal to the thickness of the flat roofing materials 10. Therefore, in the roofing structure 200, multiple flat roofing materials 10 are arranged in a stepped pattern.

[0020] <Mounting fixture> In this embodiment, a fixture 100 is used for the roofing structure 200 as described above. The fixture 100 of this embodiment includes a base material 2. The fixture 100 of this embodiment also includes an erection member 4 and a clamping and fixing means 5. The fixture 100 including the base material 2, the erection member 4, and the clamping and fixing means 5 is referred to as fixture 101.

[0021] <Base material> 2A, 2B, 2C, and 2D show the base material 2. The base material 2 is a member that reinforces the flat roofing material 10. The base material 2 is a member that makes the front end (eaves side end) of the flat roofing material 10 less susceptible to damage such as chipping and cracking.

[0022] The base material 2 is made of metal and can be formed by bending, drilling, or other processes on a thin metal plate having a thickness of, for example, about 0.3 to 0.5 mm. The metal plate can be a painted steel plate or a plated steel plate. The base material 2 is a plate-like member with a substantially J-shaped cross section, and includes a base material main body 20, a folded portion 21, an insertion portion 22, and a front piece 27.

[0023] The base material main body 20 is formed in a rectangular shape in a plan view, with the dimension in the front-rear direction being longer than the dimension in the left-right direction. The base material main body 20 is formed in a flat plate shape with flat front and back surfaces.

[0024] The insertion portion 22 is located at the rear end of the base material body 20. The insertion portion 22 is formed in the shape of a flat plate with flat front and back surfaces.

[0025] The front piece 27 is formed in a rectangular shape when viewed from the front. The front piece 27 is formed to protrude downward from the front end of the base material main body 20 at a substantially right angle.

[0026] The folded portion 21 is provided so as to protrude rearward at a substantially right angle from the lower end of the front piece 27. The folded portion 21 is located at the front end of the base material main body 20 (forward of the center in the front-to-rear direction). Therefore, the back surface (lower surface) of the front end of the base material main body 20 faces the front surface (upper surface) of the folded portion 21 with a gap therebetween. The gap between the front end of the base material main body 20 and the folded portion 21 corresponds to the vertical dimension of the front piece 27. The folded portion 21 has a recessed portion 23, a pair of installation portions 26, a locking piece 24, and a through hole 25.

[0027] The recessed portion 23 is formed near the center in the left-right direction (a direction perpendicular to the front-rear direction in a plan view) of the folded portion 21. The pair of installation portions 26 are formed on both sides (the right and left sides) of the recessed portion 23. The recessed portion 23 protrudes toward the base material main body 20 when viewed from the pair of installation portions 26. In other words, the recessed portion 23 is located above the pair of installation portions 26.

[0028] The locking piece 24 is formed in the recessed portion 23. The locking piece 24 is formed toward the rear in approximately the center in the left-right direction of the recessed portion 23. The locking piece 24 is formed by cutting out a part of the recessed portion 23, leaving one piece on the eaves side. The tip of the locking piece 24 on the ridge side protrudes downward below the underside (back surface) of the recessed portion 23.

[0029] The through holes 25 are located at least on both sides of the recessed portion 23. In this embodiment, a plurality of through holes 25 are provided on both left and right sides of the recessed portion 23. A plurality of through holes 25 are formed in each of the installation portions 26. The plurality of through holes 25 penetrate the installation portion 26 in the up and down direction.

[0030] <Installation members> 3A, 3B, and 3C show the installation member 4. The installation member 4 is a member on which the functional member S is placed and fixed. The installation member 4 is made of metal, and can be formed, for example, by bending or drilling a steel beam having a thickness of about 0.5 to 1.5 mm. Painted or plated steel beams can be used as the steel beam. In this embodiment, the installation member 4 can be formed by processing a C-beam. The installation member 4 comprises an installation material main body 40, an eave-side insertion portion 41, and a ridge-side insertion portion 42. The installation material main body 40, the eave-side insertion portion 41, and the ridge-side insertion portion 42 are integrally formed.

[0031] The construction material body 40 is a member with a generally C-shaped cross section that opens upward. The construction material body 40 is formed long so as to extend in the front-to-rear direction in a plan view. The construction material body 40 has a bottom piece 401, a pair of side pieces 402, and a pair of top pieces 403.

[0032] The bottom piece 401 is formed in a flat plate shape and extends in the front-to-rear direction. The pair of side pieces 402 are provided on the right and left sides of the bottom piece 401, respectively. The pair of side pieces 402 are formed to protrude upward from the bottom piece 401 at approximately a right angle. The pair of upper pieces 403 are provided on the side pieces 402, respectively. The pair of upper pieces 403 are formed to protrude from the side piece 402 at approximately a right angle toward the right or left. The pair of upper pieces 403 are located above the bottom piece 401.

[0033] The eaves side insertion portion 41 has a connecting piece 410, an upper fixing piece 411, a front end piece 412, a lower fixing piece 413, a contact piece 414, and a front insertion piece 415. The connecting piece 410 is formed in a flat plate shape and is formed so as to protrude forward from the front end of the bottom piece 401 of the erection material main body 40. The upper fixing piece 411 is formed in a flat plate shape and is formed so as to protrude forward from the front end of the connecting piece 410. The front end piece 412 is formed in a flat plate shape and is formed so as to protrude downward at approximately a right angle from the front end of the upper fixing piece 411.

[0034] The lower fixed piece 413 is formed in a flat plate shape and protrudes rearward at approximately a right angle from the lower end of the front end piece 412. The abutting piece 414 is formed in a flat plate shape and protrudes downward at approximately a right angle from the rear end of the lower fixed piece 413. The front insertion piece 415 is formed in a flat plate shape and protrudes rearward (towards the ridge) at approximately a right angle from the lower end of the abutting piece 414.

[0035] The eaves side insertion portion 41 has a portion that protrudes forward from the front end of the erection material main body 40. In other words, the upper fixing piece 411, the lower fixing piece 413, and the front end piece 412 of the eaves side insertion portion 41 are positioned so as to protrude forward from the front end of the erection material main body 40.

[0036] The eaves side insertion portion 41 is formed so that its ridge side end is disposed along the recessed portion 23 of the base material 2. Specifically, the front insertion piece 415 at the ridge side end of the eaves side insertion portion 41 is formed so that it is disposed along the back surface (lower surface) of the recessed portion 23.

[0037] On the other hand, the ridge-side insertion portion 42 is formed to protrude downward from the rear end portion of the construction material main body 40. The ridge-side insertion portion 42 has a bent piece 421 and a rear insertion piece 422. The bent piece 421 is formed in a flat plate shape, and is formed to protrude downward from the rear end of the bottom piece 401 of the construction material main body 40. The rear insertion piece 422 is formed in a flat plate shape, and is formed to protrude rearward (toward the ridge side) at approximately a right angle from the lower end of the bent piece 421.

[0038] The ridge-side insertion portion 42 is formed so as to be disposed along the recessed portion 23 of the base material 2. Specifically, the rear insertion piece 422 at the ridge-side end of the ridge-side insertion portion 42 is formed so as to be disposed along the back surface (lower surface) of the recessed portion 23.

[0039] The eaves-side insertion portion 41 and the ridge-side insertion portion 42 each have a locking opening 43. The locking piece 24 of the base material 2 is locked into the locking opening 43 during construction. The locking opening 43 of the eaves-side insertion portion 41 is formed as a front locking opening 431. The front locking opening 431 is formed in the front insertion piece 415. The front locking opening 431 is rectangular in plan view and is formed to pass through the front insertion piece 415 from top to bottom.

[0040] The locking opening 43 of the ridge-side insertion portion 42 is formed as a rear locking opening 432. The rear locking opening 432 is formed in the rear insertion piece 422. The rear locking opening 432 is rectangular in plan view, and is formed to penetrate the rear insertion piece 422 from top to bottom.

[0041] <Pinching and fixing means> The clamping and fixing means 5 is a member that clamps and fixes the erection member 4 to the flat roofing material 10 to which the base material 2 is attached. Specifically, as shown in FIG. 1 , the clamping and fixing means 5 is formed with a bolt 50 and a nut 51. The clamping and fixing means 5 is provided at a location that protrudes forward (toward the eaves) from the front end of the erection material main body 40. Specifically, the clamping and fixing means 5 is provided on the upper fixing piece 411 and the lower fixing piece 413 that are located forward from the front end of the erection material main body 40. The upper fixing piece 411 and the lower fixing piece 413 each have fixing holes 416, and bolts 50 are inserted into the two fixing holes 416 that face each other vertically and are fastened with nuts 51. In this way, the upper fixing piece 411 and the lower fixing piece 413 are clamped vertically between the heads of the bolts 50 and the nuts 51, and the clamping and fixing means 5 can be attached.

[0042] <Installation of fixtures> The fixture 101 is installed on the roofing structure 200 after the flat roofing material 10 has been installed. The fixture 101 is installed on the base material 2 and the erection member 4 in that order.

[0043] As shown in FIG. 1, the base material 2 is attached to the eaves side end of each of multiple flat roofing materials 10. The base material 2 is attached to each flat roofing material 10, approaching it from the eaves side. The base material main body 20 of the base material 2 is positioned so as to cover a portion of the front side (eaves side end) of the flat roofing material 10. The folded portion 21 of the base material 2 is also positioned so as to cover a portion of the back side (eaves side end) of the flat roofing material 10. As a result, the eaves side end of the flat roofing material 10 is sandwiched vertically between the base material main body 20 and the folded portion 21. The eaves side end of the flat roofing material 10 is also embraced (covered) by the base material main body 20, the folded portion 21, and the front piece 27. The base material 2 is positioned with the front piece 27 abutting the eaves side end face (front surface) of the flat roofing material 10.

[0044] The folded portion 21 is inserted between the flat roofing material 10 to which the base material 2 is attached and the flat roofing material 11 one step closer to the eaves than the flat roofing material 10. At this time, the eaves side end of the flat roofing material 10 to which the base material 2 is attached is lifted slightly upward to form a gap between it and the flat roofing material 11 on the one step closer to the eaves, and the folded portion 21 is inserted into this gap.

[0045] The folded portion 21 is also adhesively fixed to at least the flat roofing material 11 on the eaves side of the first step. In this case, liquid adhesive is applied to the installation portion 26 of the folded portion 21 before it is inserted into the gap. The folded portion 21, which has adhesive applied, is inserted and sandwiched between the underside (backside) of the flat roofing material 10 and the top side (front side) of the flat roofing material 11, and the pressure generated at this time spreads the adhesive. The adhesive also spreads over the entire front and back sides of the installation portion 26 through the multiple through holes 25. As a result, the top side of the installation portion 26 is adhesively bonded to the underside of the flat roofing material 10, and the bottom side of the installation portion 26 is adhesively bonded to the top side of the flat roofing material 11.

[0046] Furthermore, because the recessed portion 23 is located higher than the pair of mounting portions 26, the adhesive is less likely to seep in. Therefore, the recessed portion 23 of the folded portion 21 is hardly bonded to the flat roofing materials 10, 11. The underside of the recessed portion 23 faces the upper surface of the flat roofing material 11 on the first-stage eaves side, with a gap between them. The tip of the locking piece 24 of the base material 2 is located in this gap.

[0047] The insertion portion 22 is inserted between the flat roofing material 10 with the base material 2 attached and the flat roofing material 12 one step closer to the ridge than the flat roofing material 10. At this time, the eaves side end of the flat roofing material 12 on the one step closer to the ridge is lifted slightly upward to form a gap between it and the flat roofing material 10 with the base material 2 attached, and the insertion portion 22 is inserted into this gap.

[0048] In this manner, the base material 2 is applied to a plurality of flat roofing materials 10. In this embodiment, the base material 2 is applied to the flat roofing material 10 and the flat roofing material 12 on the first ridge side (the flat roofing material adjacent to the ridge side of the flat roofing material 10). The folded portion 21 of the base material 2 attached to the flat roofing material 12 is located on the surface side of the insertion portion 22 of the base material 2 attached to the flat roofing material 10. It is also preferable to adhere the base material 2 attached to the flat roofing material 12 on the first ridge side, and in this case, it is preferable that the folded portion 21 is located further toward the ridge than the insertion portion 22 of the base material 2 attached to the flat roofing material 10, which makes it easier to adhere the top surface of the flat roofing material 10 to the folded portion 21 of the base material 2 attached to the flat roofing material 12 on the first ridge side.

[0049] Next, the erection member 4 is attached. The erection member 4 is erected on two or more base members 2 arranged side by side in the eaves-ridge direction. In this embodiment, the erection member 4 is bridged between the base member 2 attached to the flat roofing material 10 and the base member 2 attached to the flat roofing material 12.

[0050] The erection member 4 is erected by engaging with the front end of the base material 2. Specifically, the eave side insertion portion 41 of the erection member 4 is engaged with the front end of the base material 2 attached to the flat roof material 10, and the ridge side insertion portion 42 of the erection member 4 is engaged with the front end of the base material 2 attached to the flat roof material 12 on the first ridge side.

[0051] The eaves-side insertion portion 41 is brought close to the eaves side of the base material 2 attached to the flat roofing material 10, and the front insertion piece 415 is inserted into the gap between the recessed portion 23 and the flat roofing material 11 on the first eaves side. This positions the front insertion piece 415 along the back surface of the recessed portion 23. In addition, the locking piece 24 of the base material 2 fits from above into the front locking opening 431 provided in the front insertion piece 415. This causes the locking piece 24 to hook onto the opening edge on the ridge side of the front locking opening 431. In this way, the eaves-side insertion portion 41 of the erection member 4 is locked to the front end of the base material 2 attached to the flat roofing material 10.

[0052] Meanwhile, the ridge-side insertion portion 42 is approached from the eaves side of the base material 2 attached to the flat roofing material 12, and the rear insertion piece 422 is inserted into the gap between the recessed portion 23 and the insertion portion 22 of the base material 2 attached to the flat roofing material 12. As a result, the rear insertion piece 422 is positioned along the back surface of the recessed portion 23. Also, the locking piece 24 of the base material 2 fits from above into the rear locking opening 432 attached to the rear insertion piece 422. As a result, the locking piece 24 hooks onto the opening edge of the rear locking opening 432 on the ridge side. In this way, the ridge-side insertion portion 42 of the erection member 4 is locked to the front end of the base material 2 attached to the flat roofing material 12.

[0053] The abutment piece 414 of the erection member 4 abuts against the eaves side surface of the front piece 27 of the base material 2, and serves as a stopper to prevent the eaves side insertion portion 41 and the ridge side insertion portion 42 from being inserted too far.

[0054] The installation member 4 is also fixed to at least one base material 2. In this embodiment, the installation member 4 is fixed to the base material 2 attached to the flat roofing material 10. A clamping and fixing means 5 is used to fix the installation member 4. Specifically, after the installation member 4 is spanned across two or more base materials 2 in a locked state as described above, the clamping and fixing means 5 is used to fix the installation member 4 to the portion of the eaves-side insertion portion 41 that protrudes from the front end of the installation material main body 40. That is, by tightening the bolt 50 and nut 51 of the clamping and fixing means 5 to reduce the gap between the connecting piece 410 and the front insertion piece 415, the eaves-side end of the flat roofing material 10 is clamped between the connecting piece 410 and the front insertion piece 415. At this time, the base material main body 20 of the base material 2 is interposed between the connecting piece 410 and the upper surface of the flat roofing material 10. In addition, a folded portion 21 is interposed between the front insertion piece 415 and the underside of the flat roofing material 10. This allows the erection member 4 to be fixed to the eaves side end of the flat roofing material 10.

[0055] Furthermore, since the base material 2 is provided at the eaves side end of the flat plate roofing material 10, the eaves side end of the flat plate roofing material 10 can be reinforced with the base material 2, making it less likely that damage such as chipping or cracking will occur at the eaves side end of the flat plate roofing material 10 when the erection member 4 is fixed. Note that it is sufficient that at least the base material 2 closest to the eaves of the base material 2 to which the erection member 4 is attached is adhered to the flat plate roofing material 10, and it is more preferable that the other base materials 2 are also adhered to the flat plate roofing material 10.

[0056] <Installation of functional components> The functional member S is applied to the roofing structure 200 after the fixture 101 has been attached as described above. The functional member S is fixed to the fixture 101 by any fixing means.

[0057] 1, a solar panel, which is a functional component S, is fixed by a fixing jig 6. The fixing jig 6 includes a bolt 60, a locking member 61, a width adjusting member 62, a retainer 63, and a nut 64.

[0058] The head 601 of the bolt 60 is arranged below the upper piece 403 of the erection member 4. The locking device 61 is a plate-shaped member, and the shank 602 of the bolt 60 is inserted vertically through it. The locking device 61 is located between the head 601 of the bolt 60 and the upper piece 403. The width adjustment member 62 is a member with a U-shaped cross section, and the shank 602 of the bolt 60 is inserted vertically through it. The width adjustment member 62 is located above the locking device 61 and the upper piece 403. The clamp 63 has a pair of clamping pieces 631 that protrude in the eaves direction and the ridge direction. The shank 602 of the bolt 60 is inserted vertically through the clamp 63. The clamp 63 is located above the width adjustment member 62. The nut 64 is connected to the shank 602 above the clamp 63.

[0059] Functional members S, which are solar panels, are arranged on the eaves side and ridge side, sandwiching the fixing jig 6. Two functional members S are each placed on the upper piece 403 of the installation member 4. The end faces of the two functional members S abut against the width adjustment members 62, adjusting the distance between the two functional members S. Then, by tightening the nut 64 onto the bolt 60, the locking device 61 is clamped between the head 601 and the upper piece 403, thereby fixing the fixing jig 6 to the installation member 4. Furthermore, by tightening the nut 64 onto the bolt 60, the end of the functional member S is clamped in the vertical direction between the pressing piece 631 of the pressing member 63 and the upper piece 403. This allows the functional member S to be fixed to the mounting fixture 101.

[0060] (Embodiment 2) The mounting fixture 100 for the functional member S according to this embodiment differs from the mounting fixture 101 according to embodiment 1 in the configuration of the base material 2 and the installation member 4. The mounting fixture 100 for the functional member S according to this embodiment also differs from the mounting fixture 101 according to embodiment 1 in the configuration in which it has a fixing member 3.

[0061] Hereinafter, the same components as those in embodiment 1 will be denoted by the same reference numerals and will not be described further. The components described in embodiment 2 can be applied in appropriate combination with the components described in embodiment 1. The fixture 100 in this embodiment is denoted by the reference numeral 102.

[0062] The fixture 102 of this embodiment includes a base member 2, a fixing member 3, and a bridging member 4. The fixture 102 does not include the clamping and fixing means 5 of the first embodiment.

[0063] <Base material> 5A and 5B show the base material 2 of this embodiment. The base material 2 of this embodiment differs from the base material 2 of embodiment 1 in that it does not have the recessed portion 23 and the locking piece 24, but the other configurations are approximately the same. The base material 2 is a plate-like member with an approximately J-shaped cross section, and has a base material main body 20, a folded-back portion 21, an insertion portion 22, and a front piece 27.

[0064] The base material main body 20 is formed in a rectangular shape in a plan view, with the dimension in the front-rear direction being longer than the dimension in the left-right direction. The base material main body 20 is formed in a flat plate shape with flat front and back surfaces.

[0065] The insertion portion 22 is located at the rear end of the base material body 20. The insertion portion 22 is formed in the shape of a flat plate with flat front and back surfaces.

[0066] The front piece 27 is formed in a rectangular shape when viewed from the front. The front piece 27 is formed to protrude downward from the front end of the base material main body 20 at a substantially right angle.

[0067] The folded portion 21 is provided so as to protrude rearward at a substantially right angle from the lower end of the front piece 27. The folded portion 21 is located at the front end of the base material main body 20 (forward of the center in the front-to-rear direction). Therefore, the back surface (lower surface) of the front end of the base material main body 20 faces the front surface (upper surface) of the folded portion 21 with a gap therebetween. The gap between the front end of the base material main body 20 and the folded portion 21 corresponds to the vertical dimension of the front piece 27.

[0068] The folded portion 21 is formed in a flat plate shape. The folded portion 21 has a plurality of through holes 25. The through holes 25 are located at both left and right ends of the folded portion 21. The through holes 25 penetrate the folded portion 21 in the up-down direction.

[0069] <Installation members> The erection member 4 of this embodiment differs from the erection member 4 of embodiment 1 in that it does not have the eaves-side insertion portion 41 and the ridge-side insertion portion 42, but otherwise has approximately the same configuration. The erection member 4 has an erection material main body 40 and a pair of fixing pieces 405. The erection material main body 40 is a member with a roughly C-shaped cross section that opens upward. The erection material main body 40 is also formed long so that it extends in the front-to-rear direction in a plan view. The erection material main body 40 has a bottom piece 401, a pair of side pieces 402, and a pair of top pieces 403.

[0070] The bottom piece 401 is formed in a flat plate shape and extends in the front-to-rear direction.

The pair of side pieces 402 are formed to protrude upward from the bottom piece 401 at approximately a right angle. The pair of upper pieces 403 are provided on the side pieces 402, respectively. The pair of upper pieces 403 are formed to protrude from the side piece 402 at approximately a right angle toward the right or left. The pair of upper pieces 403 are located above the bottom piece 401. The pair of fixing pieces 405 are provided so as to protrude oppositely from the inner walls of the pair of opposing side pieces 402, with a gap between them. The pair of fixing pieces 405 are provided between the bottom piece 401 and the upper piece 403.

[0071] <Fixing material> The fixing member 3 is a member for fixing the erection member 4 to the flat roofing material 10 to which the base material 2 is attached. The fixing member 3 has an upper holding portion 30, a lower support portion 31, a connecting portion 32, and a joining portion 33. The upper holding portion 30 is formed to be curved upward. The lower support portion 31 is formed in a flat plate shape. The upper holding portion 30 and the lower support portion 31 are arranged opposite each other vertically. The connecting portion 32 is located on the eaves side of the upper holding portion 30 and the lower support portion 31, and connects the upper holding portion 30 and the lower support portion 31. The joining portion 33 is provided on the upper holding portion 30 and protrudes upward.

[0072] <Installation of fixtures> The fixture 102 is installed on the roofing structure 200 after the flat roofing material 10 has been installed. The fixture 102 is installed on the base material 2, the fixing member 3, and the erection member 4 in this order.

[0073] The base material 2 is installed in the same manner as in the first embodiment. As shown in FIG. 4, the base material 2 is attached to the eaves side end of each of the flat roofing materials 10. The base material 2 is attached to each flat roofing material 10, approaching it from the eaves side. The base material body 20 of the base material 2 is positioned so as to cover a portion of the front side (eaves side end) of the flat roofing material 10. The folded portion 21 of the base material 2 is positioned so as to cover a portion of the back side (eaves side end) of the flat roofing material 10. As a result, the eaves side end of the flat roofing material 10 is sandwiched vertically between the base material body 20 and the folded portion 21. The eaves side end of the flat roofing material 10 is embraced (covered) by the base material body 20, the folded portion 21, and the front piece 27. The base material 2 is positioned so that the front piece 27 abuts the eaves side end face (front surface) of the flat roofing material 10.

[0074] The folded portion 21 is inserted between the flat roofing material 10 to which the base material 2 is attached and the flat roofing material 11 one step closer to the eaves than the flat roofing material 10. At this time, the eaves side end of the flat roofing material 10 to which the base material 2 is attached is lifted slightly upward to form a gap between it and the flat roofing material 11 on the one step closer to the eaves, and the folded portion 21 is inserted into this gap.

[0075] The folded portion 21 is also adhesively fixed to at least the flat roofing material 11 on the eaves side of the first step. In this case, liquid adhesive is applied to the folded portion 21 before it is inserted into the gap. The folded portion 21, which has adhesive applied, is inserted and sandwiched between the underside (backside) of the flat roofing material 10 and the top side (front side) of the flat roofing material 11, and the pressure generated at this time spreads the adhesive. The adhesive also spreads over the entire front and back sides of the folded portion 21 through the multiple through holes 25. As a result, the top side of the folded portion 21 and the underside of the flat roofing material 10 are adhesively bonded, and the bottom side of the folded portion 21 and the top side of the flat roofing material 11 are adhesively bonded.

[0076] The insertion portion 22 is inserted between the flat roofing material 10 with the base material 2 attached and the flat roofing material 12 one step closer to the ridge than the flat roofing material 10. At this time, the eaves side end of the flat roofing material 12 on the one step closer to the ridge is lifted slightly upward to form a gap between it and the flat roofing material 10 with the base material 2 attached, and the insertion portion 22 is inserted into this gap.

[0077] In this manner, the base material 2 is applied to a plurality of flat roofing materials 10. In this embodiment, the base material 2 is applied to the flat roofing material 10 and the flat roofing material 12 on the first ridge side (the flat roofing material 12 adjacent to the ridge side of the flat roofing material 10). The folded portion 21 of the base material 2 attached to the flat roofing material 12 is located on the surface side of the insertion portion 22 of the base material 2 attached to the flat roofing material 10. It is also preferable to adhere the base material 2 attached to the flat roofing material 12 on the first ridge side, and in this case, it is preferable that the folded portion 21 is located further toward the ridge than the insertion portion 22 of the base material 2 attached to the flat roofing material 10, which makes it easier to adhere the top surface of the flat roofing material 10 to the folded portion 21 of the base material 2 attached to the flat roofing material 12 on the first ridge side.

[0078] Next, the fixing member 3 is attached. The fixing member 3 is fixed to the flat roofing material 10 by sandwiching the eaves side end of the flat roofing material 10 with the base material 2 attached between the upper clamping portion 30 and the lower support portion 31. The lower support portion 31 of the fixing member 3 is inserted between the underside of the folded portion 21 of the base material 2 attached to the flat roofing material 10 and the upper surface of the flat roofing material 11 on the first eaves side of the flat roofing material 10. The upper clamping portion 30 of the fixing member 3 abuts against the upper surface of the base material main body 20 of the base material 2.

[0079] The fixing member 3 is also attached to the eaves side end of the flat roofing material 12, which is one ridge closer to the flat roofing material 10. In this case, the lower support part 31 of the fixing member 3 is inserted between the underside of the folded part 21 of the base material 2 attached to the flat roofing material 12 and the upper surface of the insertion part 22 of the base material 2 attached to the flat roofing material 10.

[0080] Next, the erection member 4 is attached. The erection member 4 is erected on two or more fixing members 3 arranged side by side in the eaves-ridge direction. In this embodiment, the erection member 4 is bridged between the fixing member 3 attached to the flat roofing material 10 and the fixing member 3 attached to the flat roofing material 12.

[0081] The erection member 4 can be fixed to the fixed member 3 by inserting the connecting portion 33 of the fixed member 3 into the bottom piece 401 and sandwiching the bottom piece 401 from above and below between the nut 34 provided on the connecting portion 33 and the upper holding portion 30 of the fixed member 3.

[0082] Then, by tightening the nut 34 provided on the joint 33, the gap between the joint 33 and the lower support part 31 is narrowed, and the fixing member 3 is fixed to the eaves side end of the flat roof material 10. Also, by using a double nut with nuts 34 and 35, loosening can be suppressed.

[0083] <Installation of functional components> The functional member S is installed on the roofing structure 200 after the mounting fixture 102 is attached. The functional member S is fixed to the mounting fixture 102 by any fixing means. In this embodiment, the functional member S can be installed using the fixing jig 6, as in the first embodiment.

[0084] (Embodiment 3) The fixture 100 for the functional member S according to this embodiment differs from the fixture 102 according to the second embodiment in the configurations of the base member 2 and the fixing member 3.

[0085] Hereinafter, the same components as those in the first or second embodiment will be denoted by the same reference numerals and explanations thereof will be omitted as appropriate.

[0086] The fixture 103 of this embodiment includes a base member 2, a fixing member 3, and a mounting member 4. The fixture 103 does not include the clamping and fixing means 5 of the first embodiment.

[0087] <Base material> 7A, 7B, and 7C show the base material 2 of this embodiment. The base material 2 of this embodiment differs from the base material 2 of embodiment 1 in that it does not have the recessed portion 23, the locking piece 24, and the insertion portion 22, but the other configurations are approximately the same. The base material 2 is a plate-like member with an approximately J-shaped cross section, and has a base material main body 20, a folded-back portion 21, and a front piece 27.

[0088] The base material main body 20 is formed in a rectangular shape in a plan view, with the dimension in the front-to-back direction being longer than the dimension in the left-to-right direction. The base material main body 20 has an inclined piece 201 formed in a position forward of the center in the front-to-back direction. The portion in front of this inclined piece 201 is formed as a main body front part 202, and the portion behind the inclined piece 201 is formed as a main body rear part 203. The main body front part 202 and the main body rear part 203 are each formed in a flat plate shape. The main body front part 202 has an insertion hole 204 that penetrates in the up-down direction.

[0089] The front piece 27 is formed in a rectangular shape when viewed from the front. The front piece 27 is formed to protrude downward at a substantially right angle from the front end of the base material main body 20 (the front end of the main body front part 202).

[0090] The folded portion 21 is provided so as to protrude rearward from the lower end of the front piece 27. The folded portion 21 is located at the front end of the base material main body 20 (forward of the center in the front-to-rear direction). Therefore, the back surface (lower surface) of the main body front part 202 of the base material main body 20 faces the front surface (upper surface) of the folded portion 21 with a gap therebetween.

[0091] The folded portion 21 is formed in a flat plate shape. The folded portion 21 has a plurality of through holes 25. The through holes 25 are located at both left and right ends of the folded portion 21. The through holes 25 penetrate the folded portion 21 in the up-down direction. A step portion 211 is provided at the front end of the folded portion 21.

[0092] <Fixing material> The fixing member 3 is a member for fixing the erection member 4 to the flat roofing material 10 to which the base material 2 is attached. The fixing member 3 has a fixing plate 36, a connecting portion 33, and nuts 34 and 35. The connecting portion 33 passes through the fixing plate 36 and protrudes upward. The nut 34 is attached to the connecting portion 33 above the fixing plate 36. The nut 35 is attached to the connecting portion 33 above the nut 34.

[0093] <Installation of fixtures> The fixture 103 is installed on the roofing structure 200 after the flat roofing material 10 has been installed. After the fixing member 3 is attached to the base material 2, the installation member 4 is installed on the fixture 103.

[0094] The fixing member 3 is attached to the main body front part 202 at the front end of the base material 2. At this time, the fixing plate 36 is placed below the main body front part 202, and the connecting part 33 is inserted into the insertion hole 204 from below. Then, the nut 34 is tightened on the upper side of the main body front part 202, thereby attaching the fixing member 3 to the base material 2. In addition, by using a double nut with nuts 34 and 35, loosening can be prevented.

[0095] Next, the base material 2 with the fixing members 3 attached is installed. As shown in FIG. 6, the base material 2 is attached to the eaves side end of each of the flat roofing materials 10. The base material 2 is attached to each flat roofing material 10, approaching it from the eaves side. The base material body 20 of the base material 2 is positioned so as to cover a portion of the front side (eaves side end) of the flat roofing material 10. The folded portion 21 of the base material 2 is also positioned so as to cover a portion of the back side (eaves side end) of the flat roofing material 10. As a result, the eaves side end of the flat roofing material 10 is sandwiched vertically between the base material body 20 and the folded portion 21. The eaves side end of the flat roofing material 10 is also embraced (covered) by the base material body 20, the folded portion 21, and the front piece 27. The base material 2 is positioned so that the step portion 211 abuts the eaves side end face (front surface) of the flat roofing material 10.

[0096] The folded portion 21 is inserted between the flat roofing material 10 to which the base material 2 is attached and the flat roofing material 11 one step closer to the eaves than the flat roofing material 10. At this time, the eaves side end of the flat roofing material 10 to which the base material 2 is attached is lifted slightly upward to form a gap between it and the flat roofing material 11 on the one step closer to the eaves, and the folded portion 21 is inserted into this gap.

[0097] The folded portion 21 is also adhesively fixed to at least the flat roofing material 11 on the eaves side of the first step. In this case, liquid adhesive is applied to the folded portion 21 before it is inserted into the gap. The folded portion 21, which has adhesive applied, is inserted and sandwiched between the underside (backside) of the flat roofing material 10 and the top side (front side) of the flat roofing material 11, and the pressure generated at this time spreads the adhesive. The adhesive also spreads over the entire front and back sides of the folded portion 21 through the multiple through holes 25. As a result, the top side of the folded portion 21 and the underside of the flat roofing material 10 are adhesively bonded, and the bottom side of the folded portion 21 and the top side of the flat roofing material 11 are adhesively bonded.

[0098] In this manner, the base material 2 is applied to multiple flat roofing materials 10. In this embodiment, the base material 2 is applied to the flat roofing materials 10 and the flat roofing material 12 on the first ridge side (the flat roofing material 12 adjacent to the ridge side of the flat roofing material 10). Note that the base material 2 in this embodiment is not inserted between the flat roofing materials 10 where the ridge side end of the main body rear part 203 overlaps in the eaves ridge direction, but is inserted below the step portion 211 of the base material 2 applied to the flat roofing material 12 on the first ridge side.

[0099] The fixing member 3 attached to the base material 2 is arranged with the fixing plate 36 positioned between the upper surface of the eaves side end of the flat roof material 10 and the front part 202 of the main body.

[0100] Next, the erection member 4 is attached. The erection member 4 is erected on two or more fixing members 3 arranged side by side in the eaves-ridge direction. In this embodiment, the erection member 4 is bridged between the fixing member 3 attached to the flat roofing material 10 and the fixing member 3 attached to the flat roofing material 12.

[0101] The erection member 4 can be fixed to the fixed member 3 by inserting the connecting portion 33 of the fixed member 3 into the bottom piece 401 and sandwiching the bottom piece 401 from above and below between the nut 34 provided on the connecting portion 33 and the upper holding portion 30 of the fixed member 3.

[0102] Then, by tightening the nut 34 provided on the joint 33, the gap between the joint 33 and the lower support part 31 is narrowed, and the fixing member 3 is fixed to the eaves side end of the flat roof material 10. Also, by using a double nut with nuts 34 and 35, loosening can be suppressed.

[0103] <Installation of functional components> The functional member S is installed on the roofing structure 200 after the mounting fixture 103 is attached. The functional member S is fixed to the mounting fixture 103 by any fixing means. In this embodiment, the functional member S can be installed using the fixing jig 6, as in the first embodiment.

[0104] (Embodiment 4) The fixture 100 for the functional member S according to this embodiment differs from the fixture 103 according to the third embodiment in the configuration of the base material 2.

[0105] Hereinafter, the same components as those in the first to third embodiments will be denoted by the same reference numerals and explanations thereof will be omitted as appropriate.

[0106] The mounting fixture 104 of this embodiment includes a base material 2, a fixing member 3, and an installation member 4. The mounting fixture 103 does not include the clamping and fixing means 5 of the first embodiment. The fixing member 3 and the installation member 4 of the mounting fixture 104 are formed in the same manner as the fixing member 3 and the installation member 4 of the third embodiment.

[0107] <Base material> The base material 2 of this embodiment is the base material 2 of embodiment 3 with an insertion portion 22 formed therein. The insertion portion 22 is provided so as to protrude rearward from the rear body portion 203. Furthermore, the base material 2 of this embodiment does not have a step portion 211 formed therein as in the base material 2 of embodiment 3.

[0108] <Installation of fixtures> The fixture 104 is installed on the roofing structure 200 after the flat roofing material 10 has been installed. After the fixing member 3 is attached to the base material 2, the installation member 4 is installed on the fixture 104.

[0109] The fixing member 3 is attached to the front body part 202 at the front end of the base member 2 in the same manner as in the third embodiment.

[0110] Next, the base material 2 with the fixing members 3 attached is installed. As shown in Figure 8, the base material 2 is attached to the eaves side end of each of the multiple flat roofing materials 10. The base material 2 is attached to each flat roofing material 10, approaching it from the eaves side. The base material main body 20 of the base material 2 is positioned so as to cover a portion of the front side (eaves side end) of the flat roofing material 10. The folded portion 21 of the base material 2 is also positioned so as to cover a portion of the back side (eaves side end) of the flat roofing material 10. As a result, the eaves side end of the flat roofing material 10 is sandwiched between the base material main body 20 and the folded portion 21 in the vertical direction. The eaves side end of the flat roofing material 10 is also embraced (covered) by the base material main body 20, the folded portion 21, and the front piece 27.

[0111] The folded portion 21 is inserted between the flat roofing material 10 to which the base material 2 is attached and the flat roofing material 11 one step closer to the eaves than the flat roofing material 10. At this time, the eaves side end of the flat roofing material 10 to which the base material 2 is attached is lifted slightly upward to form a gap between it and the flat roofing material 11 on the one step closer to the eaves, and the folded portion 21 is inserted into this gap.

[0112] The folded portion 21 is also adhesively fixed to at least the flat roofing material 11 on the eaves side of the first step. In this case, liquid adhesive is applied to the folded portion 21 before it is inserted into the gap. The folded portion 21, which has adhesive applied, is inserted and sandwiched between the underside (backside) of the flat roofing material 10 and the top side (front side) of the flat roofing material 11, and the pressure generated at this time spreads the adhesive. The adhesive also spreads over the entire front and back sides of the folded portion 21 through the multiple through holes 25. As a result, the top side of the folded portion 21 and the underside of the flat roofing material 10 are adhesively bonded, and the bottom side of the folded portion 21 and the top side of the flat roofing material 11 are adhesively bonded.

[0113] The insertion portion 22 is inserted between the flat roofing material 10 with the base material 2 attached and the flat roofing material 12 one step closer to the ridge than the flat roofing material 10. At this time, the eaves side end of the flat roofing material 12 on the one step closer to the ridge is lifted slightly upward to form a gap between it and the flat roofing material 10 with the base material 2 attached, and the insertion portion 22 is inserted into this gap.

[0114] In this way, the base material 2 is applied to multiple flat roofing materials 10. In this embodiment, the base material 2 is applied to the flat roofing material 10 and the flat roofing material 12 on the first ridge side (the flat roofing material 12 adjacent to the ridge side of the flat roofing material 10). The folded portion 21 of the base material 2 attached to the flat roofing material 12 is located on the surface side of the insertion portion 22 of the base material 2 attached to the flat roofing material 10.

[0115] The fixing member 3 attached to the base material 2 is arranged with the fixing plate 36 positioned between the upper surface of the eaves side end of the flat roof material 10 and the front part 202 of the main body.

[0116] Next, the bridging member 4 is attached. The bridging member 4 is attached to the fixing member 3 in the same manner as in the third embodiment.

[0117] <Installation of functional components> The functional member S is installed on the roofing structure 200 after the mounting fixture 104 is attached. The functional member S is fixed to the mounting fixture 104 by any fixing means. In this embodiment, the functional member S can be installed using the fixing jig 6, as in the first embodiment.
