[0009] Hereinafter, embodiments of the present invention will be described with reference to the drawings. The embodiments of the invention according to claims 1 and 2 are mainly described in paragraphs

[0018] to

[0020] and

[0031] . Figures 1 to 7 show one embodiment of the structure of the present invention. As shown in Figures 1 and 2, this structure is applied to a carport for two passenger cars. Furthermore, this structure uses solar panels 2 as the roofing material, and serves both as a carport and a solar power generation facility.

[0010] As shown in Figures 1 and 2, this structure comprises two gate-shaped frames 8 spaced apart in the front-to-back direction, each frame having a beam 7 suspended on left and right columns 6, 6, and a roof 9 supported on the frames 8. As shown in Figure 2, the front frame 8 is higher than the rear frame 8, and the roof 9 is sloped so that it is lower at the rear.

[0011] As shown in Figures 1 and 2, the roof 9 is constructed by erecting multiple rafters 1, 1, ... at regular intervals in the left-right direction on two beams 7 aligned in the front-to-back direction, erecting a front frame 10 at the above-water ends of the multiple rafters 1, 1, ..., erecting gutters 11 at the below-water ends of the multiple rafters 1, 1, ..., and erecting solar panels 2 between each rafter 1, 1, .... Five solar panels 2 are installed in the left-to-right direction and three in the front-to-back direction. As shown in Figures 3 and 4, the solar panel 2 has a rectangular frame 12 and a solar cell panel 13 held inside the frame 12.

[0012] The pillars 6 are made of aluminum extrusions with a roughly square cross section, and are installed vertically with their lower parts buried in the ground and the periphery hardened with mortar, and the upper ends of the pillars 6 are fixed to the underside of the beams 7 via connecting fittings 14, as shown in Figure 3. The upper ends of the pillars 6 can be connected to the underside of the beams 7 at any position in the longitudinal direction of the beams 7, and the installation position of the pillars 6 can be moved left and right.

[0013] As shown in Figure 3, the beam 7 is made of an aluminum extrusion with a roughly rectangular cross section. As shown in Figures 1 and 4, the beam 7 protrudes laterally beyond the column 6, and a cap 15 is attached to the end to close the small end. A rafter 1 (end rafter 1a) is installed on the end of the beam 7 protruding from the column 6. As shown in Figure 3, the beam 7 has a flat upper surface to which an auxiliary mounting member 16 made of an aluminum extrusion is attached along the longitudinal direction. The auxiliary mounting member 16 has two holder parts 18 spaced apart in the front-to-rear direction, which hold the back plate 17 so that it can slide freely in the longitudinal direction, and the front and rear holder parts 18, 18 are connected at the top by a connecting part 71. Then, a rafter mounting bracket 19 attached to the side of the rafter 1 is placed across the front and rear holder parts 18, 18, and bolts 20 are screwed from above into the back plates 17, 17 held by the front and rear holder parts 18, 18 and tightened, so that the rafter 1 can be attached to any position in the longitudinal direction of the beam 7.

[0014] The mounting support material 16 has a length that covers almost the entire length of the beam 7, and as shown in Figure 8(a), it is placed on the top surface of the beam 7 and fixed to the beam 7 from above in the holder part 18 with screws 41. Then, as shown in Figure 8(b), the required number of back plates 17 are inserted into the holder part 18 from the small end, and then, as shown in Figure 8(c), caps 42 are attached to the end of the mounting support material 16 to cover the small end.

[0015] In this way, this structure has mounting auxiliary material 16 having holder portions 18, 18 attached to the upper surface of beam 7, so there is no need to form holder portion 18 on beam 7, and mounting auxiliary material 16 can be used in places other than this structure where components cross and connect with each other, thereby reducing costs. The mounting auxiliary material 16 has two integral holder parts 18, 18, making it easy to mount on the beam 7. The two holder parts 18, 18 are connected at the top, and a space 43 (see Figure 3) is formed between the holder parts 18, 18. Therefore, even if a protrusion is formed on the top surface of the beam 7 or the head of a bolt 44 protrudes (see Figure 24), the mounting auxiliary material 16 can be mounted without any problems by accommodating the protrusion or the head of the bolt 44 in the space 43.

[0016] The intermediate rafter 1b, which is installed at the midpoint of the longitudinal direction of the beam 7, is formed from an aluminum profile and, as shown in Figure 6, has a hollow section 21 with a horizontally long rectangular cross-section located at the bottom, a narrower hollow section 22 located above it, gutter sections 23, 23 formed on both the left and right sides of the hollow section 22, a groove section 24 located above the narrow hollow section 22, and support sections 4, 4 extending out to the left and right at the upper end.

[0017] A back plate 25 is held in an upper position within groove 24 so as to be slidable in the longitudinal direction. As shown in Figure 9, back plate 25 is formed with female threaded holes 45 into which bolts 29 for attaching panel retainers 28 (described later) are threaded, and clear holes 46 into which positioning screws (tapping screws) 26 are inserted. Back plate 25, with screws 26 inserted into clear holes 46, is inserted into the upper part of groove 24 from the small end. As shown in Figure 10(a), a pilot hole 46 is formed in the bottom wall 27 of the groove portion 24, into which the tip of the screw 26 can be engaged at a predetermined position in the longitudinal direction.When the back plate 25 is slid longitudinally in the groove portion 24, as shown in Figures 10(a) and (b), the tip of the screw 26 engages with the pilot hole 46, and the back plate 25 is positioned at a predetermined position in the longitudinal direction of the intermediate rafter 1b. 10(c), the back plate 25 is fixed by rotating the screw 26 and screwing it into the pilot hole 46. In this way, the back plate 25 is positioned and installed at a predetermined position in the longitudinal direction of the intermediate rafter 1b.

[0018] As shown in Figure 6, the side edges of the left and right solar panels 2, 2 are placed on the mounting parts 4, 4 of the intermediate rafter 1b, and a panel holder 28 is placed from above between the left and right solar panels 2, 2, and a bolt 29 is inserted into the panel holder 28 from above and screwed into the female threaded hole 45 of the back plate 25 and tightened, thereby sandwiching the left and right solar panels 2, 2 from above and below between the panel holder 28 and the mounting parts 4, 4, and fixing the left and right solar panels 2, 2 to the intermediate rafter 1b. Note that this structure is capable of mounting solar panels 2 with different height dimensions H, as will be described later. A drainage hole (not shown) is formed in the bottom wall 27 of the groove portion 24, and the inside of the narrow hollow portion 22 and the inside of the gutter portions 23, 23 provided on both sides thereof form drainage channels D1, D2 for draining rainwater that seeps in between the solar panels 2, 2, ... into the gutter 11.

[0019] As shown in Figures 3 and 4, below the gaps between the solar panels 2, 2 lined up in the front-to-back direction, groove-shaped cross beams 30 with open tops are installed between the gutter sections 23 of adjacent rafters 1, 1, .... Rainwater seeping in through the gaps between the solar panels 2, 2 lined up in the front-to-back direction flows through the cross beams 30 into the gutter sections 23 of the rafters 1.

[0020] As shown in Figure 7, panel receivers 58 are attached to the upper surfaces of the rafters 1, 1, ... at positions between the solar panels 2, 2 lined up in the front-to-rear direction. The panel receivers 58 are made of metal and have a roughly L-shaped cross section, and receive the underwater ends of the solar panels 2 located above the water, thereby positioning the solar panels 2 in the front-to-rear direction. In addition, a joint material 31 made of an aluminum extrusion is attached to the gap between the solar panels 2, 2 arranged in front and behind, and the gap is closed by the joint material 31. The joint material 31 is attached to the panel receiver 58 by screwing it with a screw 63 from above. The joint material 31 also has a pressing piece 59 that presses down from above the above-water end of the solar panel 2 located below the water.

[0021] The end rafter 1a, which is installed at the longitudinal end of the beam 7, is formed from an aluminum profile, and as shown in Figure 5, has a rectangular cross-sectional hollow portion 21 located at the bottom, a narrower hollow portion 22 located above it towards the outer periphery, a gutter portion 23 formed on the inner periphery of the hollow portion 22, a groove portion 24 located above the narrow hollow portion 22, a support portion 4 that extends inward from the upper end of the inner periphery wall of the groove portion 24, and a side wall 32 formed by extending the outer periphery wall of the groove portion 24 upward. A back plate 25 is held in an upper position within the groove 24 so as to be slidable in the longitudinal direction. Similar to the back plate 25 of the intermediate rafter 1b described above, the back plate 25 is positioned at a predetermined position in the longitudinal direction of the end rafter 1a by inserting a screw 26 from above and screwing it into a pilot hole 46 formed in the bottom wall 27 of the groove 24 (see Figure 10). The side wall 32 has an upper end that is bent obliquely inward to form a receiving portion 5 that receives the end panel retainer 3. The inside of the narrow hollow portion 22 and the inside of the gutter portion 23 on its inner periphery, like the intermediate rafter 1b, serve as drainage channels D1, D2 for draining rainwater that seeps in between the solar panels 2, 2, ... into the gutter 11.

[0022] As shown in Figure 5, an end panel holder 3 that holds down the side edge of the solar panel 2 is attached to the end rafter 1a above the groove 24. The end panel holder 3 has a hollow portion 33, a panel holder portion 34 that extends from the upper wall of the hollow portion 33 toward the inner periphery, a first locking portion 35 that extends from the upper wall of the hollow portion 33 toward the outer periphery, and a second locking portion 36 that protrudes from the outer periphery side at a position spaced downward from the first locking portion 35. The first locking portion 35 is inclined obliquely downward toward the outer periphery and has a downwardly curved tip. The second locking portion 36 is inclined obliquely downward.

[0023] As shown in FIG. 5, this structure is capable of mounting two types of solar panels 2 with different height dimensions H (for example, two types with height dimensions H of 30 mm and 35 mm). When installing the solar panel 2 with the lower height dimension H, as shown in Figure 5(a), the side edge of the solar panel 2 is placed on the support portion 4 of the end rafter 1a, and then the first locking portion 35 of the end panel holder 3 is locked with the receiving portion 5 of the end rafter 1a, and the panel holder portion 34 is locked on the top surface of the solar panel 2. Then, a bolt 29 is inserted into the end panel holder 3 from above and screwed into the back plate 25 held in the groove portion 24 of the end rafter 1a and tightened, thereby sandwiching the solar panel 2 from above and below between the panel holder portion 34 of the end panel holder 3 and the support portion 4 of the end rafter 1a, and fixing the solar panel 2 to the end rafter 1a. The end panel holder 3 holds the solar panel 2 with the panel holder portion 34 on the inner periphery, and is supported by the receiving portion 5 of the end rafter 1a, preventing it from tipping outward. The end panel holder 3 is attached at a slight incline so that the upper surface is slightly higher toward the inner periphery, which allows the inner periphery panel holder 34 to firmly hold down the solar panel 2 and also allows rainwater on the end panel holder 3 to fall to the outer periphery of the roof 9. The first engaging portion 35 also serves as a rain guard that covers the outer periphery of the side wall 32 of the end rafter 1a, thereby preventing rainwater from seeping in between the side wall 32 of the end rafter 1a and the end panel holder 3. The frame 12 of the solar panel 2 is hidden by the side wall 32 of the end rafter 1a and the end panel holder 3.

[0024] When installing a solar panel 2 with a higher height dimension H, the second locking portion 36 of the end panel retainer 3 is locked onto the receiving portion 5 of the end rafter 1a, as shown in Figure 5(b). This allows the end panel retainer 3 to be installed in a higher position than when installing a solar panel 2 with a lower height dimension H (see Figure 5(a)), and the solar panel 2 with a higher height dimension H can be fixed to the end rafter 1a. In this case, too, the end panel retainer 3 holds the solar panel down with the inner panel retainer portion 34, and is supported by the receiving portion 5 of the end rafter 1a, preventing the solar panel from tipping outwards.

[0025] As shown in Figure 3, the front frame 10 is erected on the above-water ends of the multiple rafters 1, 1, ..., and hides the ends of the rafters 1, 1, .... A front panel holder (rising portion) 39 formed separately from the front frame 10 is attached by screws to the top surface of the front frame 10, and the front panel holder 39 hides the frame 12 of the solar panel 2. Furthermore, when the front panel holder 39 is attached to the top surfaces of the rafters 1, 1, ..., the ends of the end panel holders 3 and panel holders 28 that hold down the side edges of the solar panels 2, 2, ... are also hidden by the front panel holder 39, as shown in Figure 18.

[0026] As shown in Figures 3 and 11, the underwater ends of the rafters 1, 1, ... have a hollow portion 21 cut out at the bottom, and a gutter fixing bracket 47 is attached to the underwater ends of the rafters 1, 1, ... from the underwater side so that the hollow portion 21 spans the upper and lower surfaces of the underwater ends of the cut-out rafters 1, 1, ... The gutter fixing bracket 47 is made of an aluminum extrusion and has a panel receiving piece 48 formed on the front upper side for receiving the frame 12 of the solar panel 2, and a mounting piece 49 formed on the rear side for attaching the gutter 11. The lower part of the gutter fixing bracket 47 is formed with a locking groove 50 for locking the gutter 11 and a fixing part 51 for connecting to the rafters 1. A water guide part 52 is formed on the rear side of the fixing part 51 for receiving rainwater flowing from the drainage channels D1, D2 of the rafters 1 and directing it into the gutter 11.

[0027] As shown in Figures 3 and 15, the gutter 11 is installed on the underwater ends of the rafters 1, 1, ... via gutter fixing fittings 47. As shown in Figure 16, the gutter 11 is made of aluminum extrusion and formed with a roughly U-shaped cross section with an open top, and has a locking piece 53 at the upper end of the front (abovewater) side wall that locks into a locking groove 50 of the gutter fixing fitting 47, and has an overlapping piece 54 at the top of the rear (belowwater) side wall that overlaps under the mounting piece 49 of the gutter fixing fitting 47. The rear side wall protrudes upward to form a rising portion 40. As shown in Figure 16(a), when the locking piece 53 of the gutter 11 is engaged with the locking groove 50 of the gutter fixing bracket 47 from the lower rear side and the overlapping piece 54 is abutted against the mounting piece 49 of the gutter fixing bracket 47 from below, the above-water end of the gutter 11 abuts against the lower part of the rafters 1, 1, ... as shown in Figure 16(b), and the gutter 11 will not fall even if you let go of it. With the gutter 11 temporarily placed, a screw (drill screw) 56 is inserted from above into the screw insertion hole 57 previously formed in the mounting piece 49 and locking groove 51 of the gutter fixing bracket 47, and the screw 56 is rotated to screw into the overlapping piece 54 and locking piece 53 of the gutter 11, as shown in Figure 16(c), thereby attaching the gutter 11 to the gutter fixing bracket 47.

[0028] By installing the gutter 11 at the downstream ends of the multiple rafters 1, 1, ..., the edges of the rafters 1, 1, ... are hidden by the gutter 11, as shown in Figure 3. In addition, the rising portion 40 formed on the gutter 11 hides the frame 12 of the solar panel 2 and the edges of the end panel holders 3 and panel holders 28 that hold down the side edges of the solar panels 2, 2, ....

[0029] As described above, in this structure, the gutter 11 is installed on the underwater ends of the rafters 1, 1, ... via gutter fixing fittings 47, so a gap 60 (see Figures 3 and 26) is formed between the underwater ends of the solar panels 2 located on the underwater side and the gutter 11. In order to prevent light from entering the space under the roof through the gaps 60, this structure has a shading element 61 installed between the rafters 1, 1, ... near the underwater end, as shown in Figures 3, 15, and 26. The shading element 61 is made of an aluminum extrusion with an L-shaped cross section, and has a horizontal side 61a that is screwed to the rafter 1 from above, and a vertical piece 61b that rises upward. By attaching the shading part 61 in this way, as shown in Figure 3, light 62 entering through the gap 60 between the underwater end of the solar panel 2 and the gutter 11 is blocked by the shading part 61, preventing the light 62 from entering the space under the roof. The presence of the shading part 61 also prevents rain and wind from entering through the gap 60 between the underwater end of the solar panel 2 and the gutter 11. The shading parts 61 may be attached to the underside of the rafters 1, 1, ..., but by installing the shading parts 61 between the rafters 1, 1, ... as shown in Figures 3 and 26, the shading parts 61 can be easily installed and can be made less noticeable.

[0030] Next, the construction procedure for this structure will be explained. First, as shown in Figure 19-1(a), the lower parts of the pillars 6 are embedded in embedding holes drilled in the ground, and the pillars 6 are erected vertically in the designated positions. Next, as shown in 19-1(b), the beams 7, 7 are connected to the left and right pillars 6, 6 with connecting metal fittings 14 and erected. Next, as shown in Figure 19-2(c), the mounting aids 16 are screwed onto each beam 7 from above. After that, as shown in Figure 8(b), the required number of backing plates 17 are inserted into the holder parts 18 of the mounting aids 16 from the small ends, and as shown in Figure 8(c), caps 42 are attached to the ends of the mounting aids 16. Each backing plate 17 is slid to its approximate position, referring to the mounting pitch of the rafters 1, 1, ... Next, as shown in Figure 19-2(d), the rafters 1,1,... are attached at a specified pitch across the front and rear beams 7,7. At this time, as shown in Figure 13, the rafters 1,1,... can be easily attached at a specified pitch by abutting the slit portions 65 of the scale 64, which are formed to match the pitch of the rafters 1,1,..., against the vertical pieces 19a of the rafter mounting brackets 19 attached to the sides of adjacent rafters 1,1. Note that, as shown in Figures 9 and 10, a back plate 25 is attached in advance to each rafter 1 at a specified position in the longitudinal direction, and as shown in Figure 11, a gutter fixing bracket 47 is attached in advance to the downstream end. Next, as shown in FIG. 19-3(e), horizontal beams 30, 30, . . . and light-shielding parts 61, 61, . . . are attached between the rafters 1, 1, . Next, as shown in Figure 19-3(f), the front frame 10 is erected on the above-water ends of the rafters 1, 1, ... Next, as shown in FIG. 19-4(g), a gutter 11 is installed at the downstream end of the rafters 1, 1, . . . Next, as shown in FIG. 19-4(h), a vertical gutter 66 is installed from the gutter 11 to the pillar 6.

[0031] The following steps are carried out by a solar panel installer. First, as shown in Figure 19-5(i), panel supports 58, 58, ... are attached to rafters 1, 1, .... Next, as shown in Figure 19-5(j), the solar panels 2, 2, ... are placed between the rafters 1, 1, ..., and the panel holders 3, 28 and joint material 31 are attached to fix the solar panels 2, 2, ... to the rafters 1, 1, .... The solar panels 2, 2, ... are installed from either the left or right side to the other, and are installed in order starting from the underwater side. First, as shown in Figure 17(a), the underwater side solar panel 2 is placed between the rafters 1, 1 with its underwater end abutting against the panel support piece 48 attached to the gutter fixing bracket 47. Next, as shown in Figure 17(b), the middle solar panel 2 is placed between the rafters 1, 1 with its underwater end abutting against the panel support 58 attached to the rafter 1. Next, as shown in Figure 17(c), the abovewater side solar panel 2 is similarly placed between the rafters 1, 1 with its underwater end abutting against the panel support 58. After that, the panel holders 3, 28 and joint material 31 are installed to secure the solar panels 2, 2, ... to the rafters 1, 1, ... In this way, by positioning the solar panels 2, 2, . . . based on the panel receiving pieces 48 and panel receiving pieces 58 of the gutter fixing fittings 47, the solar panels 2, 2, . Thereafter, as shown in FIG. 19-6(k), the rising portion 39 is attached to the front frame 10.

[0032] So far we have explained carports for two cars, but by connecting multiple carports together in the left and right direction as shown in Figure 20, this structure can be constructed to accommodate four cars (see Figure 20(b)), six cars (see Figure 20(c)), eight cars, etc., and can be constructed to any length. Even when connecting multiple carports (Figures 20(b) and (c)), the pitch P1 of the pillars 6 is the same as that of a single (2-car) carport (Figure 20(a)). The pitch P2 of the rafters 1 is also a common dimension according to the size of the solar panels 2, and the total length L of the beams 7 is a multiple of the pitch P2 of the rafters 1. The beam 7 has both ends extending from the end columns 6 by the same distance A, and a rafter 1 (end rafter 1a) is attached to the tip of the extending beam 7. The beam 7 is divided into multiple pieces along the length depending on the number of connected buildings (two for a two-unit building, three for a three-unit building), and is connected at the center of the middle column 6. In this structure, the pitch P1 of the columns 6 is the same for a single column, a two-column column, a three-column column, ... a multi-column column, but the overhang length A of the beams 7 from the end columns 6 is different. How much the beams 7 should overhang from the end columns 6 can be easily calculated from the pitch P1 and number of columns 6 and the total length L of the beams 7.

[0033] In this way, this structure is easy to construct because the pitch P1 of the pillars 6 is the same whether it is a single unit or a multiple-unit building, and the only difference is the overhang length A of the beams 7 from the end pillars 6.As in the case of a single unit described above, the rafters 1, 1, ... are attached to the beams 7 at a specified pitch P2, and the solar panels 2, 2, ... are erected sequentially between the rafters 1, 1, ..., allowing the roof 9 to be easily constructed.

[0034] 21 to 26 show another embodiment of the structural body of the present invention, which is applied to a two-unit carport for four cars. As shown in Figure 21, the beam 7 is divided into two parts, left and right beams 7a and 7b, which are connected on the middle column 6. In detail, as shown in Figure 22, a connecting fitting 14 is attached to the underside of a cylindrical sleeve 67 with a substantially rectangular cross section, the sleeve 67 is inserted into the hollow parts of the divided left and right beams 7a and 7b, the beams 7a and 7b and the sleeve 67 are fixed from above and below with bolts 44, the connecting fitting 14 is inserted into the hollow part of the column 6, and the column 6 and the connecting fitting 14 are fixed with bolts 68 from the front and back. Furthermore, as shown in Figure 23, the joints of the beams 7a and 7b are sealed with a sealant, and then a cover 69 is attached to cover the joints of the beams 7a and 7b. As shown in Figures 23 and 24, the heads of the bolts 44 are exposed on the upper surfaces of the beams 7a and 7b, but since the mounting auxiliary material 16 attached to the upper surfaces of the beams 7a and 7b has a space 43 formed between the front and rear holder portions 18, 18, the heads of the bolts 44 can be accommodated in that space 43, allowing the mounting auxiliary material 16 to be attached without any problems.

[0035] As shown in Figures 25 and 26, the gutter 11 is divided into multiple pieces in the longitudinal direction and then connected at the intermediate rafter 1b. In detail, as shown in Figure 25(a), waterstops 70 are attached to the end faces of one and the other of the divided gutters 11a, 11b, and after a sealant is applied to the waterstops 70, the waterstops 70 are butted together. Then, as shown in Figure 25(b), a cover 71 is attached to cover the joint between the gutters 11a, 11b, and the periphery of the cover 71 is also sealed with a sealant. The one and other gutters 11a, 11b connected in this way are connected to the downstream end of the intermediate rafter 1b via a gutter fixing bracket 47, as shown in Figure 26. Rainwater flowing down the drainage paths D1, D2 (see Figure 6) of the intermediate rafter 1b is received by the water guide portion 52 (see Figures 11 and 16) of the gutter fixing bracket 47 and flows into the one and other gutters 11a, 11b (see arrow 72 in Figure 26). This prevents rainwater from falling from the drainage paths D1, D2 of the intermediate rafter 1b into the joint between the one and other gutters 11a, 11b, preventing rainwater from leaking from the joint between the one and other gutters 11a, 11b.

[0036] As described above, this structure comprises rafters 1,1,... and solar panels 2,2,..., with multiple rafters 1,1,... arranged at intervals and having panel holders 58 that support the underwater ends of the solar panels 2,2,..., the solar panels 2,2,... are erected between the rafters 1,1,... based on the panel holders 58, and the solar panels 2,2,... are fixed to the rafters 1,1,... with panel holders 3,28 attached to the rafters 1,1,... (see Figures 3 and 17), making it easy to attach the solar panels 2,2,... and improving workability. Furthermore, the ease of construction of this structure allows costs to be kept down. The manufacturing method of this structure is to attach panel supports 58 that support the underwater ends of the solar panels 2, 2, ... to rafters 1, 1, ... placed at intervals, place the solar panels 2, 2, ... between the rafters 1, 1, ... based on the panel supports 58, and attach panel holders 3, 28 to the top of the rafters 1, 1, ... to fix the solar panels 2, 2, ... (see Figures 3 and 17), which makes it easy to install the solar panels 2, 2, ... and improves workability. Furthermore, the manufacturing method of this structure is easy to install, which helps to reduce costs. A plurality of panel supports 58 are provided at intervals along the longitudinal direction of the rafters 1, 1, ..., and a plurality of solar panels 2, 2, ... are provided in the direction in which the rafters 1, 1, ... are arranged relative to the panel supports 58 (see Figures 3 and 17), so that a large number of solar panels 2, 2, ... can be installed, and the installation work of a large number of solar panels 2, 2, ... can be carried out efficiently. In addition, in this structure, joint material 31 is attached by screwing to panel holders 58 in the gaps between the solar panels 2, 2, ... that are lined up in the longitudinal direction of the rafters 1, 1, ... (see Figures 3 and 7), so that the joint material 31 fills the gaps between the solar panels 2, 2, ... and prevents rainwater from leaking through the gaps between the solar panels 2, 2, ... Since the joint material 31 is made of metal, gaps are prevented from opening between the solar panels 2, 2, . . . in the event of a fire, and the roof 9 can be made fireproof.

[0037] This structure comprises one member (beam) 7, the other member (rafter) 1 arranged to intersect with the first member 7, and an attachment auxiliary member 16. The attachment auxiliary member 16 is provided on either side of the first member 7 along the longitudinal direction of the first member 7 and has a holder portion 18 in the longitudinal direction. The other member 1 can be fixed freely at any position in the longitudinal direction of the first member 7 via the holder portion 18 of the attachment auxiliary member 16 (see Figure 3), making it easy to attach the other member 1 and improving workability. The mounting auxiliary material 16 has a pair of holder portions 18, 18 and a connecting portion 71 that connects the pair of holder portions 18, 18, and the other member 1 is positioned across the pair of holder portions 18, 18 (see Figure 3), so that the spacing between the pair of holder portions 18, 18 is maintained constant and the other member 1 can be firmly fixed via the pair of holder portions 18, 18. This structure has a fixture (back plate) 17 held by holder portions 18, 18 so that it can slide freely in the longitudinal direction, and the other member 1 is fixed by the fixture 17 (see Figure 3), so it is easy to fix the other member 1 to any position in the longitudinal direction of one member 7.

[0038] This structure comprises a rafter 1, one and the other gutters 11a, 11b arranged with their ends facing each other, and a gutter fixing bracket 47, and the gutter fixing bracket 47 fixes the ends of the one and the other gutters 11a, 11b to the downstream end of the rafter 1 (see Figure 26), thereby simplifying the construction of the gutter 11 and improving workability. The rafter 1 has drainage channels D1 and D2 in the longitudinal direction, and water that falls from the drainage channels D1 and D2 is received by the gutter fixing brackets 47 and flows into one and the other gutters 11a and 11b (see Figures 6 and 26), thereby preventing water from leaking from the joints between the one and the other gutters 11a and 11b.

[0039] This structure comprises rafters 1,1,..., left and right roof materials (solar panels) 2,2 placed on the rafters 1,1,..., and a panel holder 28 that secures the roof materials 2,2 to the rafters 1. The rafters 1 have a back plate 25 that can be moved longitudinally, and the back plate 25 has a positioning portion (screw) 26 that can be engaged with an engaging portion (pre-hole) 46 provided on the rafter 1 to position the back plate 25 at a predetermined position longitudinally of the rafter 1. Since the panel holder 28 is fixed to the back plate 25 (see Figures 6 and 10), the roof materials 2,2 can be easily installed, improving workability. The positioning portion 26 is composed of a screw 26 inserted into the back plate 25 from above, and the screw 26 is screwed into the rafter 1 (see Figures 6 and 10), making it easy to engage and fix the positioning portion 26 to the engaging portion 46, and using commercially available screws 26 can reduce manufacturing costs.

[0040] This structure comprises pillars 6, 6, ... arranged at a predetermined pitch P1, beams 7 supported on the pillars 6, 6, ..., and rafters 1, 1, ... arranged on the beams 7 at a predetermined pitch P2, with the overall length of the beams 7 being a multiple of the pitch P2 of the rafters 1, 1, .... The beams 7 extend from the end pillars 6, and rafters 1 are arranged on the ends of the extending beams 7 (see Figure 20), which makes it easy to construct the roof 9 and improves workability. By connecting multiple beams 7 in the longitudinal direction (see Figures 20, 21, and 22), the roof 9 can be constructed to any length in the left-right direction. In this structure, roofing materials (solar panels) 2, 2, ... are installed between each rafter 1, 1, ... (see Figures 4 and 20), which makes it easy to install the roofing materials 2, 2, ..., further improving workability.

[0041] This structure comprises rafters 1,1,..., solar panels 2,2,..., and a front frame 10, with multiple rafters 1,1,... arranged at intervals, the solar panels 2,2,... erected between the rafters 1,1,..., and the front frame 10 erected at the above-water ends of the multiple rafters 1,1,..., conceals the ends of the rafters 1,1,..., and has a rising portion (front panel holder) 39, which conceals the frames 12 of the solar panels 2,2,... (see Figure 3), thereby simplifying the construction of the roof 9 and improving workability. Moreover, because the rising portion 39 of the front frame 10 conceals the frames 12 of the solar panels 2,2,..., the design is also improved. This structure comprises rafters 1,1,..., solar panels 2,2,..., and gutters 11, with multiple rafters 1,1,... arranged at intervals, the solar panels 2,2,... erected between the rafters 1,1,..., and gutters 11 erected at the downstream ends of the multiple rafters 1,1,..., hiding the ends of the rafters 1,1,..., and having rising portions 40 which hide the frames 12 of the solar panels 2,2,... (see Figure 3), which simplifies the construction of the roof 9 and improves workability. Moreover, the rising portions 40 of the gutters 11 hide the frames 12 of the solar panels 2,2,..., which also improves design. This structure has panel holders 3, 28 that hold down the side edges of the solar panels 2, 2, . . . , and the edges of the panel holders 3, 28 are hidden by rising portions 39, 40 (see FIG. 18), further improving the design.

[0042] This structure comprises rafters 1,1, ... spaced apart, roofing materials (solar panels) 2,2, ... erected between the rafters 1,1, ..., frames (gutters) 11 erected on the longitudinal ends of the rafters 1,1, ..., and a shading part 61, which blocks light 62 that shines into the space under the roof from between the ends of the roofing materials 2,2, ... and the frame 11 (see Figure 3), thereby preventing light 62 from shining into the space under the roof from between the ends of the roofing materials 2,2, ... and the frame 11, and further preventing rain and wind from entering between the ends of the roofing materials 2,2, ... and the frame 11, making it easy to use. The light-shielding parts 61 are installed between the rafters 1 (see FIGS. 3 and 15), so that the light-shielding parts 61 can be easily attached and can be made inconspicuous.
