Description

This disclosure relates to a roof structure.

Conventionally, a roof structure is known that includes a front frame (front member), a rafter hanger (rear member), a number of rafters extending between the front frame and the rafter hanger and arranged side by side in the direction in which the front frame and the rafter hanger extend, a number of rafters extending between adjacent rafters, and a panel material supported and attached to the rafters and rafters between the adjacent rafters (see, for example, Patent Document 1).

JP 2008-208671 A

In order to improve the design of roof structures, there is a demand for structures that do not use furring strips. If furring strips are not used, there is less support for the panel material, and the panel material may bend downwards due to loads such as snow accumulation.

The objective of this disclosure is to provide a roof structure that can prevent the panel material from bending downward while improving the design.

The present disclosure relates to a roof structure comprising a front member extending in a predetermined direction, a rear member extending parallel to the front member, a plurality of rafters extending across the front member and the rear member and arranged side by side in the longitudinal direction of the front member and the rear member, a plurality of panel members attached between adjacent rafters and arranged side by side in a direction perpendicular to the longitudinal direction of the rafters, and a fixing member for restricting movement of the panel members.

The end cover member 513 is fixed to the end rafter body 511 by a cover fixing screw 531 that penetrates the end rafter 51 in the vertical direction near the outer side in the left-right direction and is screwed into the screw fixing groove portion 511b of the end rafter body 511. As shown in FIG. 2, the cover fixing screws 531 are arranged in a row at a predetermined interval in the longitudinal direction of the end rafter 51. The end cover member 513 is fixed at a predetermined interval in the longitudinal direction of the end rafter 51 by a plurality of cover fixing screws 531.

As shown in FIG. 4, the end cover member 513 has an end cover member upper plate 513a formed in a flat shape, and an end cover side gasket fitting portion 513b formed at the lower part of the inner end in the left-right direction of the end cover member upper plate 513a. The end cover side gasket fitting portion 513b is formed in a groove shape, is formed on the lower surface of the end cover member upper plate 513a with an open downward direction, and extends in the front-rear direction (the longitudinal direction of the end rafter 51). An end cover side gasket 514 is placed in the end cover side gasket fitting portion 513b.

The end cover side packing fitting portion 513b is composed of a pair of T-shaped fitting pieces 513c. The pair of fitting pieces 513c are arranged apart in the left-right direction and have a pair of falling protrusions 513d that fall downward from the lower surface of the end cover member upper plate 513a, and a pair of fitting protrusions 513e formed at the lower ends of the pair of falling protrusions 513d. The pair of fitting protrusions 513e each protrude a predetermined length on both sides in the left-right direction from the lower ends of the falling protrusions 513d.

The end cover side gasket 514 has an attachment portion 514a that is disposed between the pair of falling projections 513d, a constricted portion 514b that is disposed between the pair of engagement projections 513e and extends downward from the attachment portion 514a, and a deformation pressing portion 514c that is connected to the lower end of the constricted portion 514b and is disposed between the lower surface of the pair of engagement projections 513e and the upper surface of the panel material 6.

The end cover member 513 is fixed to the top of the end rafter body 511 with the cover fixing screw 531, so that the left and right ends of the panel material 6 are sandwiched and held between the end rafter body 511 and the end cover member 513 by the end body side gasket 512 attached to the end body side gasket fitting portion 511d and the end cover side gasket 514 attached to the end cover side gasket fitting portion 513b.

The intermediate rafter 52 is formed in a symmetrical shape as shown in FIG. 3. The intermediate rafter 52 has a structure for holding the panel material 6 in the end rafter 51 on both the left and right sides.

As shown in FIG. 3, the intermediate rafter 52 has an intermediate rafter body 521 (rafter body) and an intermediate cover member 523 (rafter cover member). The intermediate rafter body 521 is disposed below the intermediate rafter 52, and extends downwardly from the rafter hanger 3 toward the front frame 4 as shown in FIG. 1.

As shown in FIG. 5, the intermediate rafter body 521 has a hollow intermediate hollow portion 521a, a screw fixing groove portion 521b formed in the center of the upper surface of the intermediate hollow portion 521a in the left-right direction, a pair of intermediate body side packing fitting portions 521d formed at both ends of the outer left-right direction of the upper surface of the intermediate hollow portion 521a, and a pair of gutter forming portions 521h formed between the screw fixing groove portion 521b and the intermediate body side packing fitting portion 521d in the left-right direction of the upper surface of the intermediate hollow portion 521a.

The screw fixing groove 521b is composed of a pair of opposing rising walls 521c with a width that allows the shaft 532a of the cover fixing screw 532 to be screwed in and fixed. When fixing the intermediate cover member 523 to the intermediate rafter body 521, the shaft 532a of the cover fixing screw 532 that passes through the intermediate cover member 523 is screwed into the screw fixing groove 521b.

The gutter component 521h is formed by a downwardly inclined portion 521i that extends downwardly from the lower portion of the screw fixing groove portion 521b to the outside, and a horizontal portion 521j that extends horizontally from the lower end of the downwardly inclined portion 521i to the outside. The gutter component 521h directs water that has entered the interior of the intermediate rafter 52 toward the front frame 4.

The intermediate body side packing fitting portion 521d is formed at the outer end of the intermediate rafter 52 in the left-right direction. The intermediate body side packing fitting portion 521d is formed in a groove shape, is formed to open upward on the upper surface of the intermediate hollow portion 521a, and extends in the front-to-rear direction (the longitudinal direction of the intermediate rafter 52). The intermediate body side packing fitting portion 521d is formed in a roughly C-shaped groove that opens upward. The intermediate body side packing fitting portion 521d is where the intermediate body side packing 522 is placed.

The intermediate body side packing fitting portion 521d is composed of a pair of L-shaped fitting pieces 521e. The pair of fitting pieces 521e are arranged opposite each other in the left-right direction and have a pair of rising protrusions 521f rising from the upper surface of the intermediate hollow portion 521a and a pair of fitting protrusions 521g formed at the upper ends of the pair of rising protrusions 521f.

The pair of fitting protrusions 521g protrude toward each other in the direction of closing the groove-shaped opening of the intermediate body side packing fitting portion 521d. The intermediate body side packing 522 has an attachment portion 522a arranged between the pair of rising protrusions 521f of the intermediate body side packing fitting portion 521d, a constricted portion 522b arranged between the pair of fitting protrusions 521g and extending upward from the attachment portion 522a, and a deformation pressing portion 522c connected to the upper end of the constricted portion 522b and arranged between the upper surface of the pair of fitting protrusions 521g and the lower surface of the panel material 6.

The intermediate cover member 523 is placed on the upper part of the intermediate rafter body 521. The intermediate cover member 523 is fixed to the intermediate rafter body 521 by a cover fixing screw 532 that penetrates the intermediate rafter 52 in the vertical direction at the center of the left-right direction and is screwed into the screw fixing groove portion 521b of the intermediate rafter body 521. The cover fixing screws 532 are arranged in a row at a predetermined interval in the longitudinal direction of the intermediate rafter 52. As shown in FIG. 2, the intermediate cover member 523 is fixed at a predetermined interval in the longitudinal direction of the intermediate rafter 52 by a plurality of cover fixing screws 532.

5, the intermediate cover member 523 has an intermediate cover member upper plate 523a with a flat upper surface, and an intermediate cover side gasket fitting portion 523b formed at the lower part of the inner end portion in the left-right direction of the intermediate cover member upper plate 523a. The intermediate cover side gasket fitting portion 523b is formed in a groove shape, is formed on the lower surface of the intermediate cover member 523 so as to be open downward, and extends in the front-rear direction (the longitudinal direction of the intermediate rafter 52). An intermediate cover side gasket 524 is disposed in the intermediate cover side gasket fitting portion 523b.

The intermediate cover side packing fitting portion 523b is composed of a pair of T-shaped fitting pieces 523c. The pair of fitting pieces 523c are arranged apart in the left-right direction and have a pair of falling protrusions 523d that fall downward from the lower surface of the intermediate cover member upper plate 523a, and a pair of fitting protrusions 523e formed at the lower ends of the pair of falling protrusions 523d. The pair of fitting protrusions 523e each protrude a predetermined length on both sides in the left-right direction from the lower ends of the falling protrusions 523d.

The intermediate cover side gasket 524 has an attachment portion 524a that is disposed between the pair of falling projections 523d, a constricted portion 524b that is disposed between the pair of engagement projections 523e and extends downward from the attachment portion 524a, and a deformation pressing portion 524c that is connected to the lower end of the constricted portion 524b and is disposed between the lower surface of the pair of engagement projections 523e and the upper surface of the panel material 6.

When the intermediate cover member 523 is fixed to the top of the intermediate rafter body 521 by the cover fixing screw 532, the left and right ends of the panel material 6 are sandwiched and held between the intermediate rafter body 521 and the intermediate cover member 523 by the intermediate body side gasket 522 attached to the intermediate body side gasket fitting portion 521d and the intermediate cover side gasket 524 attached to the intermediate cover side gasket fitting portion 523b.

As shown in FIG. 2, among the multiple panel materials 6 arranged side by side in the left-right direction, in the multiple panel materials 62 other than the panel materials 61 arranged at both ends, the left-right ends of the panel materials 62 are held by the intermediate rafters 52 and fixed to the intermediate rafters 52 at predetermined positions in the longitudinal direction of the intermediate rafters 52 by panel fixing screws 54 (fixing members). The panel fixing screws 54 fix the intermediate rafters 52 and the panel materials 6 so as to restrict the movement of the panel materials 6.

The longitudinal position of the intermediate rafter 52, where the left and right ends of the panel material 6 are fixed by the panel fixing screws 54, is the longitudinal middle part of the intermediate rafter 52. The longitudinal middle part of the intermediate rafter 52 is the longitudinal center C of the intermediate rafter 52 or a position closer to the center. The longitudinal center position of the intermediate rafter 52 means a position closer to the center C than the end T when comparing the longitudinal center C and the end T of the intermediate rafter 52, as shown in FIG. 2.

In this embodiment, the intermediate rafter 52 is fixed at the center C or a position close to the center in the longitudinal direction of the intermediate rafter 52, for example, by two panel fixing screws 54 aligned in the longitudinal direction of the intermediate rafter 52. It is preferable that there are at least two panel fixing screws 54. The two panel fixing screws 54 are arranged at the same positions as the cover fixing screws 532 in the longitudinal direction of the intermediate rafter 52. The two panel fixing screws 54 are arranged aligned in the left-right direction with the cover fixing screws 532 at the same positions in the longitudinal direction of the intermediate rafter 52. The two panel fixing screws 54 are arranged, for example, about 100 mm to 200 mm apart in the longitudinal direction of the intermediate rafter 52. In this embodiment, the panel fixing screws 54 are arranged aligned in the left-right direction with the cover fixing screws 532 at the same positions in the longitudinal direction of the intermediate rafter 52, but this is not limited to this.

The reason why there are two panel fixing screws 54 is that it is difficult to obtain stable fixation when fixing with one panel fixing screw 54, but by fixing with two panel fixing screws 54, stable fixation can be obtained with a minimum number of screws. Note that there is no limit to the number of panel fixing screws 54.

As shown in FIG. 5, the panel fixing screws 54 are screwed vertically into the portion of the intermediate rafter 52 that holds the panel material 6. The panel fixing screws 54 are screwed vertically at a position, for example, about 5 mm to 10 mm inward from the left and right ends of the intermediate rafter 52.

When screwing in the panel fixing screw 54, as shown in FIG. 5, for example, a pilot hole P1 is drilled into a part of the intermediate cover member top plate 523a of the intermediate cover member 523 and a part of the inner fitting piece 523c in the left-right direction of the pair of fitting pieces 523c of the intermediate cover side gasket fitting portion 523b. The panel fixing screw 54 is then screwed in, from top to bottom, into the intermediate cover member top plate 523a of the intermediate cover member 523, a part of the inner fitting piece 523c in the left-right direction of the pair of fitting pieces 523c of the intermediate cover side gasket fitting portion 523b, a part of the intermediate cover side gasket 524, the panel material 6, a part of the intermediate body side gasket 522, a part of the inner fitting piece 521e in the left-right direction of the pair of fitting pieces 521e of the intermediate cover side gasket fitting portion 523b, and a part of the upper surface of the intermediate hollow portion 521a of the intermediate rafter body 521. As a result, the panel fixing screw 54 fastens the intermediate cover member 523, the panel material 6, and the intermediate rafter body 521 together, thereby fixing the intermediate rafter 52 and the panel material 6.

The panel fixing screw 54 is arranged to penetrate the intermediate cover member upper plate 523a of the intermediate cover member 523, a part of the inner fitting piece 523c in the left-right direction of the pair of fitting pieces 523c of the intermediate cover side packing fitting portion 523b, a part of the intermediate cover side packing 524, the panel material 6, a part of the intermediate body side packing 522, and a part of the inner fitting piece 521e in the left-right direction of the pair of fitting pieces 521e of the intermediate cover side packing fitting portion 523b, and is arranged in a state where it does not penetrate the upper surface of the intermediate hollow portion 521a of the intermediate rafter body 521. Since the panel fixing screw 54 is arranged in a state where it does not penetrate the upper surface of the intermediate hollow portion 521a of the intermediate rafter body 521, it is possible to prevent water from entering the interior of the intermediate hollow portion 521a.

As described above, among the multiple panel materials 6 arranged side by side in the left-right direction, in the multiple panel materials 62 other than the panel materials 61 arranged at both ends, the ends of the panel materials 6 are held by the intermediate rafters 52 and fixed to the intermediate rafters 52 by the panel fixing screws 54 at the center C in the longitudinal direction or at a position close to the center. This makes it possible to prevent the panel material 6 from shifting left-right even when pressure is applied to the top surface of the panel material 6 due to a load such as snow. Therefore, by not providing a rafter, the design is improved, while downward bending of the panel material 6 can be prevented without providing a rafter.

Here, among the multiple panel materials 6 arranged side by side in the left-right direction, the panel materials 61 arranged at both ends of the roof body 2 in the left-right direction are not fixed to the panel fixing screws 54. Even if pressure acts on the upper surface of the panel material 61 due to a load such as snow accumulation, the end rafters 51 can temporarily fall outward in the left-right direction to absorb the load acting on the upper surface of the panel material 61. By releasing the pressure due to the load on the panel material 61, the end rafters 51 and the panel material 61 can return to their original position. As a result, even if the panel materials 61 arranged at both ends of the left-right direction of the roof body 2 are not fixed by the panel fixing screws 54, the end rafters 51 can temporarily fall outward in the left-right direction to absorb the load acting on the upper surface of the panel material 61 while suppressing the bending of the panel material 61. Therefore, in this embodiment, the ends of the panel materials 61 arranged at both ends of the left-right direction of the roof body 2 are not fixed by the panel fixing screws 54.

The roof structure 2 of the first embodiment described above provides the following advantages:

The roof body 2 of this embodiment comprises a number of rafters 5 extending across the front frame 4 and the rafter hanger 3 and arranged in a line in the longitudinal direction of the front frame 4 and the rafter hanger 3, a number of panel materials 6 attached between adjacent rafters 5 and arranged in a line in a direction perpendicular to the longitudinal direction of the rafters 5, and panel fixing screws 54 that fix and restrict the movement of the panel materials 6. This improves the design while preventing the panel materials 6 from bending downward.

In this embodiment, the panel fixing screw 54 fixes the intermediate rafter 52 to the panel material 6 so as to restrict movement of the panel material 6. This allows the panel fixing screw 54 to fix the intermediate rafter 52 to the panel material 6 while ensuring the fixing strength at any position along the length of the intermediate rafter 52.

In this embodiment, the middle part of the intermediate rafter 52 in the longitudinal direction is the center C of the intermediate rafter 52 or a part close to the center. This allows the intermediate rafter 52 and the panel material 6 to be fixed with the panel fixing screw 54 at the minimum point at the center or close to the center of the intermediate rafter 52 in the longitudinal direction while ensuring the fixing strength.

In this embodiment, of the multiple panel materials 6, the panel materials 61 arranged at the ends in a direction perpendicular to the longitudinal direction of the rafters 5 are not fixed to the panel fixing screws 54. Even if the panel materials 61 arranged at both ends in the left-right direction of the roof body 2 are not fixed with the panel fixing screws 54, the end rafters 51 temporarily fall outward in the left-right direction, thereby preventing the panel materials 61 from bending and absorbing the load acting on the upper surface of the panel materials 61.

In this embodiment, the panel fixing screw 54 fixes the intermediate rafter 52 and the panel material 6 by tightening the intermediate cover member 523, the panel material 62, and the intermediate rafter body 521 together. This allows the panel fixing screw 54 to firmly fix the intermediate rafter 52 and the panel material 6 in a state that is unlikely to fall over.

In this embodiment, the panel fixing screws 54 are positioned so that they do not penetrate the upper surface of the intermediate rafter body 521. This prevents water from entering the interior of the intermediate rafter body 521.

Next, the roof body 2A of the second embodiment will be described. The roof body 2A of the second embodiment differs from the roof body 2 of the first embodiment mainly in that, while the rafters 5 (end rafters 51, intermediate rafters 52) of the first embodiment are composed of a rafter body and a rafter cover member, the rafters 5A (end rafters 56, intermediate rafters 57) of the second embodiment are composed without a rafter cover member. The rest of the configuration of the second embodiment is the same as that of the first embodiment. In describing the configuration of the second embodiment, the description of the same configuration as that of the first embodiment may be omitted.

As shown in Figs. 6 and 7, the roof body 2A of the second embodiment includes a rafter hanger 3 (rear member), a front frame 4 (front member) arranged at a distance from the rafter hanger 3, a plurality of rafters 5A arranged extending between the rafter hanger 3 and the front frame 4, and a plurality of panel materials 6 arranged between adjacent rafters 5A. The plurality of rafters 5A include two end rafters 56 arranged at both ends of the roof body 2A in the left-right direction, and a plurality of intermediate rafters 57 (rafters) arranged side by side in the left-right direction between the two end rafters 56. The end rafters 56 clamp and fix the end of the panel material 6 in the vertical direction on one side of the end rafter 56 in the left-right direction. The intermediate rafters 57 clamp and fix the end of the panel material 6 in the vertical direction on both left-right sides of the intermediate rafter 52.

As shown in FIG. 8, the end rafter 56 has an end hollow section 561 having a convex section 561a that protrudes upward on the outer side in the left-right direction, an end rafter top plate 562 that extends horizontally inward in the left-right direction from the upper surface of the convex section 561a of the end hollow section 561, an end rafter gasket fitting section 563 formed at the lower part of the inner end in the left-right direction of the end rafter top plate 562, a bead material arrangement section 564 that protrudes upward at a position lower than the convex section 561a at the inner end in the left-right direction of the end hollow section 561, and a gutter forming section 565 formed between the convex section 561a and the bead material arrangement section 564 in the left-right direction of the upper surface of the end hollow section 561.

The gutter component 565 is formed by a downwardly inclined portion 565a that extends downwardly outward from the lower portion of the convex portion 561a of the end hollow portion 561, and a horizontal portion 565b that extends horizontally outward from the lower end of the downwardly inclined portion 565a. The gutter component 565 directs water that has infiltrated inside the end rafter 56 toward the front frame 4.

The end rafter packing fitting 563 is formed in a groove shape, is formed on the underside of the end rafter upper plate 562 with an open downward direction, and extends in the left-right direction (the longitudinal direction of the end rafter). An end rafter side packing 566 is placed in the end rafter packing fitting 563.

The end rafter packing fitting portion 563 is composed of a pair of T-shaped fitting pieces 563a. The pair of fitting pieces 563a are arranged apart in the left-right direction and have a pair of downward projections 563b that extend downward from the lower surface of the end rafter upper panel 562, and a pair of fitting projections 563c formed at the lower ends of the pair of downward projections 563b. The pair of fitting projections 562c each protrude a predetermined length on both sides in the left-right direction from the lower ends of the downward projections 563b.

The end rafter side gasket 566 has an attachment portion 566a that is arranged between a pair of downward projections 563b, a constricted portion 566b that is arranged between a pair of fitting projections 563c and extends downward from the attachment portion 566a, and a deformation pressing portion 566c that is connected to the lower end of the constricted portion 566b and is arranged between the lower surface of the pair of fitting projections 563c and the upper surface of the panel material 6.

The bead material placement section 564 is formed in a convex shape that protrudes upward and extends in the front-to-rear direction (the longitudinal direction of the end rafter 56). The bead material placement section 564 is positioned below the end rafter packing fitting section 563. A bead material 567 is placed in the bead material placement section 564. The bead material 567 is placed between the panel material 6 and the bead material placement section 564 with the panel material 6 inserted between the end rafter upper plate 562 and the bead material placement section 564. The bead material 567 sandwiches the end of the panel material 6 between the end rafter side packing 566 attached to the end rafter packing fitting section 563.

With the panel material 6 inserted between the end rafter top plate 562 and the bead material placement section 564, the bead material 567 is pushed between the underside of the panel material 6 and the bead material placement section 564, whereby the left and right ends of the panel material 6 are sandwiched and held between the end rafter side gasket 566 attached to the end rafter gasket fitting section 563 and the bead material 567 placed in the bead material placement section 564.

The intermediate rafter 57 is formed in a symmetrical shape as shown in FIG. 7. The intermediate rafter 57 has a structure for holding the panel material 6 in the end rafter 56 formed on both the left and right sides.

As shown in FIG. 9, the intermediate rafter 57 has an intermediate hollow section 571 having a convex section 571a that protrudes upward in the center in the left-right direction, an intermediate rafter upper panel 572 (upper fin portion) that extends horizontally on both left-right sides from the upper surface of the convex section 571a of the intermediate hollow section 571, an intermediate rafter gasket fitting portion 573 formed at the lower part of the outer left-right end of the intermediate rafter upper panel 572, a bead material placement portion 574 (lower receiving portion) that protrudes upward at a position lower than the convex section 571a at the inner left-right end of the intermediate hollow section 571, and a gutter forming portion 575 formed between the convex section 571a and the bead material placement portion 574 in the left-right direction on the upper surface of the intermediate hollow section 571.

The gutter component 575 is formed by a downwardly inclined portion 575a that extends downwardly from the lower portion of the convex portion 571a of the intermediate hollow portion 571 to the outside, and a horizontal portion 575b that extends horizontally from the lower end of the downwardly inclined portion 575a to the outside. The gutter component 575 directs water that has infiltrated inside the intermediate rafter 57 toward the front frame 4.

The intermediate rafter packing fitting 573 is formed in a groove shape, is formed on the lower surface of the intermediate rafter upper plate 572 with an open downward direction, and extends in the front-to-rear direction (the longitudinal direction of the intermediate rafter 57). An intermediate rafter side packing 576 is placed in the intermediate rafter packing fitting 573.

The intermediate rafter packing fitting portion 573 is composed of a pair of T-shaped fitting pieces 573a. The pair of fitting pieces 573a are arranged apart in the left-right direction and have a pair of falling protrusions 573b that fall downward from the lower surface of the intermediate rafter upper panel 572, and a pair of fitting protrusions 573c formed at the lower ends of the pair of falling protrusions 573b. The pair of fitting protrusions 573c each protrude a predetermined length on both sides in the left-right direction from the lower ends of the falling protrusions 573b.

The intermediate rafter side gasket 576 has an attachment portion 576a that is positioned between a pair of falling projections 573b, a constricted portion 576b that is positioned between a pair of fitting projections 573c and extends downward from the attachment portion 576a, and a deformation pressing portion 576c that is connected to the lower end of the constricted portion 576b and is positioned between the lower surface of the pair of fitting projections 573c and the upper surface of the panel material 6.

The bead material placement section 574 is formed in a convex shape that protrudes upward and extends in the front-to-rear direction (the longitudinal direction of the intermediate rafter 57). The bead material placement section 574 is positioned below the intermediate rafter packing fitting section 573. A bead material 577 (clamping member) is placed in the bead material placement section 574. The bead material 577 is placed between the panel material 6 and the bead material placement section 574 with the panel material 6 inserted between the intermediate rafter upper plate 572 and the bead material placement section 574. The bead material 577 clamps the end of the panel material 6 between the intermediate rafter side packing 576 attached to the intermediate rafter packing fitting section 573.

With the panel material 6 inserted between the intermediate rafter top plate 572 and the bead material placement section 574, the bead material 577 is pushed between the underside of the panel material 6 and the bead material placement section 574, whereby the left and right ends of the panel material 6 are sandwiched and held between the intermediate rafter side gasket 576 attached to the intermediate rafter gasket fitting section 573 and the bead material 577 placed in the bead material placement section 574.

As shown in FIG. 6, among the multiple panel materials 6 arranged side by side in the left-right direction, in the multiple panel materials 62 other than the panel materials 61 arranged at both ends, the left-right ends of the panel materials 62 are held by the intermediate rafters 57 and fixed to the intermediate rafters 57 at predetermined positions in the longitudinal direction of the intermediate rafters 57 by panel fixing screws 58 (fixing members) in the same manner as in the first embodiment. The panel fixing screws 58 fix the intermediate rafters 57 and the panel materials 6 so as to restrict the movement of the panel materials 6.

The longitudinal position of the intermediate rafter 57, where the left and right ends of the panel material 6 are fixed by the panel fixing screws 58, is the longitudinal middle part of the intermediate rafter 57. The longitudinal middle part of the intermediate rafter 57 is the longitudinal center C of the intermediate rafter 57 or a position closer to the center. The longitudinal center position of the intermediate rafter 57 means a position closer to the center C than the end T when comparing the longitudinal center C of the intermediate rafter 57 with the end T, as shown in FIG. 6.

In this embodiment, the intermediate rafter 57 is fixed at the center C or a position close to the center in the longitudinal direction of the intermediate rafter 57 by, for example, two panel fixing screws 58 aligned in the longitudinal direction of the intermediate rafter 57. It is preferable that there are at least two panel fixing screws 58. The two panel fixing screws 58 are arranged, for example, about 100 mm to 200 mm apart in the longitudinal direction of the intermediate rafter 57.

As shown in FIG. 9, the panel fixing screws 58 are screwed vertically into the portions of the intermediate rafters 57 that hold the panel material 6. The panel fixing screws 58 are screwed vertically at positions, for example, about 5 mm to 10 mm inward from the left and right ends of the intermediate rafters 57.

When screwing in the panel fixing screw 58, as shown in Figure 9, for example, pilot holes P2 are drilled into a part of the intermediate rafter top plate 572 and a part of the inner left-right fitting piece 573a of the pair of fitting pieces 573a of the intermediate rafter gasket fitting portion 573, and the panel fixing screw 58 is screwed, in order from the top to the bottom of the intermediate rafter 57, into the intermediate rafter top plate 572, a part of the inner left-right fitting piece 573a of the pair of fitting pieces 573a of the intermediate rafter gasket fitting portion 573, a part of the intermediate rafter gasket, the panel material 6, a part of the intermediate rafter side gasket 576, a part of the bead material 577, and a part of the upper surface of the bead material placement portion 574 formed at the inner left-right end of the intermediate hollow portion 571. As a result, the panel fixing screw 58 fastens the intermediate rafter top plate 572, the panel material 6, and the bead material placement portion 574 together, thereby fixing the intermediate rafter 57 and the panel material 6.

The panel fixing screw 58 is arranged to penetrate the intermediate rafter top plate 572, a portion of the inner fitting piece 573a in the left-right direction of one of the pair of fitting pieces 573a of the intermediate rafter packing fitting portion 573, a portion of the intermediate rafter packing, the panel material 6, a portion of the intermediate rafter side packing 576, and a portion of the bead material 577, but is arranged in a state where it does not penetrate the upper surface of the bead material arrangement portion 574. Because the panel fixing screw 58 is arranged in a state where it does not penetrate the upper surface of the bead material arrangement portion 574, it is possible to prevent water from entering the interior of the intermediate hollow portion 571.

As described above, among the multiple panel materials 6 arranged side by side in the left-right direction, in the multiple panel materials 62 other than the panel materials 61 arranged at both ends, the ends of the panel materials 6 are held by the intermediate rafters 57 and fixed to the intermediate rafters 52 at the center C in the longitudinal direction or at a position close to the center by the panel fixing screws 58. This makes it possible to prevent the panel material 6 from shifting left-right even when pressure is applied to the top surface of the panel material 6 due to a load such as snow. This makes it possible to prevent the panel material 6 from bending downward while improving the design.

The roof body 2A of the second embodiment provides the same effects as the roof body 2 of the first embodiment, as well as the following effects:

In this embodiment, the panel fixing screw 58 fixes the intermediate rafter 57 and the panel material 6 by tightening the intermediate rafter top plate 572, the panel material 6, and the bead material placement portion 574 together. This allows the panel fixing screw 58 to firmly fix the intermediate rafter 57 and the panel material 6 in a state that is unlikely to fall over.

In this embodiment, the panel fixing screw 58 is positioned so that it does not penetrate the top surface of the bead material placement section 574. This prevents water from entering the interior of the intermediate rafter 57.

Next, the third to sixth embodiments will be described. The third to sixth embodiments are modified versions of the first embodiment, and are different from the first embodiment in the configuration for fixing the panel material 6. The other configurations of the third to sixth embodiments are the same as those of the first embodiment. In the description of the configurations of the third to sixth embodiments, the description of the same configurations as those of the first embodiment may be omitted. Note that in the third to fifth embodiments, only the configurations of the intermediate rafters 52A, 52B, and 52C will be described, but the configuration in which the end rafters (not shown) hold the panel material 6 is the same as the configuration in which the end rafters 51 of the first embodiment hold the panel material 6 on one side in the left-right direction of the intermediate rafters 52A, 52B, and 52C. Therefore, the description of the configuration on one side in the left-right direction of the intermediate rafters 52A, 52B, and 52C can be used to describe the configuration of the end rafters.

The intermediate rafter 52A of the third embodiment will now be described. As shown in FIG. 10, the panel material 6 of the third embodiment is not fixed to the panel fixing screw 54 of the first embodiment, but is fixed to the panel fixing rivet 71. In the third embodiment, the longitudinal position at which the panel material 6 is fixed to the panel fixing rivet 71 is the same as in the first embodiment.

As shown in FIG. 10, the panel fixing rivet 71 penetrates vertically together with the spacer member 72 (regulating member) on the end side of the panel material 6 from the portion where the panel material 6 is sandwiched between the intermediate body side packing 522 attached to the intermediate body side packing fitting portion 521d and the intermediate cover side packing 524 attached to the intermediate cover side packing fitting portion 523b in the left-right direction of the intermediate rafter 52A. The panel fixing rivet 71 penetrates vertically at a position, for example, about 15 mm inward from the left-right end of the intermediate rafter 52A.

The spacer member 72 is attached to the lower surface of the intermediate cover member top plate 523a of the intermediate cover member 523 between the intermediate cover side packing fitting portion 523b in the left-right direction and the portion fixed by the cover fixing screw 532, and is disposed between the lower surface of the intermediate cover member top plate 523a of the intermediate cover member 523 and the upper surface of the panel material 6. The spacer member 72 is disposed in the left-right direction between the downward protruding piece 523f that protrudes downward from the lower surface of the intermediate cover member top plate 523a of the intermediate cover member 523 and the intermediate cover side packing fitting portion 523b. As a result, the spacer member 72 is restricted from moving in the left-right direction by the downward protruding piece 523f of the intermediate cover member 523 and the intermediate cover side packing fitting portion 523b.

When attaching the panel fixing rivet 71, as shown in FIG. 10, the panel fixing rivet 71 is inserted through a part of the intermediate cover member upper plate 523a of the intermediate cover member 523, the spacer member 82, and the panel material 6 in that order, and the pin 711 of the panel fixing rivet 71 is pushed in. This opens the tip 712 of the panel fixing rivet 71, allowing the intermediate cover member 523, the spacer member 82, and the panel material 6 to be fixed by the panel fixing rivet 71. Note that in the third embodiment, the intermediate cover member 523 of the intermediate rafter 52A is fixed by the panel fixing rivet 71, but this is not limited to this and it may be fixed by a screw.

As a result, according to the third embodiment, as in the first embodiment, even if pressure is applied to the upper surface of the panel material 6 due to a load such as snow, it is possible to suppress the left-right displacement of the panel material 6. Therefore, by not providing a furring strip, the design is improved, while downward bending of the panel material 6 can be suppressed without providing a furring strip.

In addition, in this embodiment, a spacer member 72 whose movement in the left-right direction is restricted by the downward protruding piece 523f of the intermediate cover member 523 and the intermediate cover side packing fitting portion 523b is provided, and the panel fixing rivet 71 fixes the intermediate cover member 523, the panel material 6, and the spacer member 72. As a result, the panel fixing rivet 71 fixes the panel material 6 to the spacer member 72 whose movement in the left-right direction is restricted, so that the left-right movement of the panel material 6 can be further restricted. Therefore, downward bending of the panel material 6 can be further suppressed.

Next, the fourth embodiment of the intermediate rafter 52B will be described. As shown in FIG. 11, the panel material 6 of the fourth embodiment is not fixed to the panel fixing screw 54 of the first embodiment, but is fixed to the panel fixing screw 73. In the fourth embodiment, the longitudinal position at which the panel material 6 is fixed to the panel fixing screw 73 is the same as in the first embodiment.

As shown in FIG. 11, the panel fixing screw 73 is screwed in vertically penetrating the intermediate rafter 52B together with the base member 74 (regulating member) at the end side of the panel material 6 closer to the left and right side of the intermediate rafter 52B than the portion where the panel material 6 is sandwiched between the intermediate body side gasket 522 attached to the intermediate body side gasket fitting portion 521d and the intermediate cover side gasket 524 attached to the intermediate cover side gasket fitting portion 523b. The panel fixing screw 73 is screwed in vertically at a position, for example, about 15 mm inward from the left and right ends of the intermediate rafter 52B.

The base member 74 has a lower base portion 741 arranged below the left-right end of the panel material 6, and an upward extension portion 742 extending upward from the inner end of the lower base portion 741. The lower base portion 741 is attached to the upper surface of the gutter component 521h of the intermediate rafter body 521, and is arranged between the lower surface of the left-right end of the panel material 6 and the gutter component 521h. The upward extension portion 742 is arranged between the end face of the left-right end of the panel material 6 and one rising wall 521c of the screw fixing groove portion 521b. The base member 74 is arranged between the rising wall 521c of the intermediate rafter body 521 and the intermediate body side packing fitting portion 521d in the left-right direction. The left-right movement of the base member 74 is restricted by the rising wall 521c of the intermediate rafter body 521 and the intermediate body side packing fitting portion 521d. The base member 74 is made of, for example, an aluminum material.

When attaching the panel fixing screw 73, as shown in FIG. 11, the panel fixing screw 73 is screwed into a part of the upper surface plate 523a of the intermediate cover member 523, the panel material 6, and the lower base portion 741 of the base member 74 in that order, thereby fixing the intermediate cover member 523, the panel material 6, and the base member 74 with the panel fixing screw 73.

As a result, according to the fourth embodiment, as in the first embodiment, even if pressure is applied to the upper surface of the panel material 6 due to a load such as snow, it is possible to suppress the left-right displacement of the panel material 6. Therefore, by not providing a furring strip, the design is improved, while the panel material 6 is prevented from bending downwards even without providing a furring strip.

In addition, in this embodiment, a base member 74 is provided whose movement in the left-right direction is restricted by the rising wall 521c of the intermediate rafter body 521 and the intermediate body side packing fitting portion 521d, and the panel fixing screw 73 fixes the intermediate cover member 523, the panel material 6, and the panel fixing screw 73. As a result, the panel material 6 is fixed to the base member 74 whose movement in the left-right direction is restricted by the panel fixing screw 73, so that the movement of the panel material 6 in the left-right direction can be further restricted. Therefore, downward bending of the panel material 6 can be further suppressed.

Next, the intermediate rafter 52C of the fifth embodiment will be described. As shown in FIG. 12, the panel material 6 of the fifth embodiment is not fixed by the panel fixing screw 54 of the first embodiment, but is fixed by the panel fixing screw 75. In the fifth embodiment, the longitudinal position at which the panel material 6 is fixed by the panel fixing screw 75 is the same as in the first embodiment.

As shown in FIG. 12, the panel fixing screw 75 is screwed in vertically penetrating the intermediate rafter 52C together with the upper reinforcing plate member 76 (regulating member) at the end side of the panel material 6 closer to the left and right side of the intermediate rafter 52C than the portion where the panel material 6 is sandwiched between the intermediate body side gasket 522 attached to the intermediate body side gasket fitting portion 521d and the intermediate cover side gasket 524 attached to the intermediate cover side gasket fitting portion 523b. The panel fixing screw 75 is screwed in vertically penetrating the intermediate rafter 52C at a position, for example, about 15 mm inward from the left and right ends.

The upper reinforcing plate member 76 is formed on the upper surface of the intermediate cover member upper plate 523a of the intermediate cover member 523, extending in the left-right direction. The upper reinforcing plate member 76 is fixed to the intermediate cover member 523 and the intermediate rafter body 521 by a cover fixing screw 532 that penetrates the center in the left-right direction. The upper reinforcing plate member 76 has an upper plate portion 761 that extends in the left-right direction on the upper surface of the intermediate cover member 523, and a pair of downward protruding pieces 762 that are formed on both left-right ends of the upper plate portion 761 and protrude downward.

The upper plate portion 761 has a pair of thick portions 761a. The pair of thick portions 761a are arranged at a distance in the left-right direction and are formed thickly to protrude upward between the intermediate cover side packing fitting portion 523b and the portion fixed by the cover fixing screw 532 in the left-right direction of the upper plate portion 761. The pair of downward protruding pieces 762 protrude downward along the outer side surfaces on both left-right sides of the intermediate cover member 523. The pair of downward protruding pieces 762 of the upper reinforcing plate member 76 are arranged along the outer side surfaces on both left-right sides of the intermediate cover member 523, so that movement in the left-right direction is restricted.

When attaching the panel fixing screw 75, as shown in FIG. 12, with the upper reinforcing plate member 76 placed on the top surface of the intermediate cover member 523, the panel fixing screw 75 is screwed into the thick portion 761a of the upper plate portion 761 of the upper reinforcing plate member 76, a part of the intermediate cover member upper plate 523a of the intermediate cover member 523, and the panel material 6, in that order, so that the panel fixing screw 75 can be tightened in the thick portion 761a of the upper plate portion 761 of the upper reinforcing plate member 76, and the intermediate cover member 523 and the panel material 6 can be fixed by the panel fixing screw 75.

As a result, according to the fifth embodiment, as in the first embodiment, even if pressure is applied to the upper surface of the panel material 6 due to a load such as snow, it is possible to suppress the left-right displacement of the panel material 6. Therefore, by not providing a furring strip, the design is improved, while the panel material 6 is prevented from bending downwards, even without providing a furring strip.

In addition, in this embodiment, a pair of downward protruding pieces 762 are arranged along the outer side surfaces on both left and right sides of the intermediate cover member 523, thereby providing an upper reinforcing plate member 76 whose movement in the left and right direction is restricted, and the intermediate cover member 523 and the panel material 6 are fixed by the panel fixing screw 75. As a result, the panel material 6 is fixed to the upper reinforcing plate member 76 whose movement in the left and right direction is restricted by the panel fixing screw 75, so that the movement of the panel material 6 in the left and right direction can be further restricted. Therefore, downward bending of the panel material 6 can be further suppressed.

In addition, in this embodiment, the upper reinforcing plate member 76 is placed on the upper surface of the intermediate cover member 523, thereby restricting the left-right movement of the upper reinforcing plate member 76. Therefore, when screw fixing with the panel fixing screws 75, by forming screw holes in the upper reinforcing plate member 76, the upper reinforcing plate member 76 can be simply placed on the upper surface of the intermediate cover member 523, and the construction of screw fixing with the panel fixing screws 75 can be easily performed without using a jig for positioning the screw, for example.

Next, the intermediate rafter 52D of the sixth embodiment will be described. As shown in Figures 13 and 14, the panel material 6 of the sixth embodiment is not fixed by the panel fixing screws 54 of the first embodiment, but is fixed by hat-shaped fittings 77 (restraining members). In the sixth embodiment, the longitudinal position at which the panel material 6 is fixed by the hat-shaped fittings 77 is a position including the longitudinal center C of the intermediate rafter 52D, as shown in Figure 13. The hat-shaped fittings 77 extend in the longitudinal direction of the intermediate rafter 52D, including the longitudinal center C of the intermediate rafter 52D, at the longitudinal center C of the intermediate rafter 52D or at a position close to the center.

As shown in Figures 13 and 15, the hat-shaped fitting 77 extends a predetermined length in the longitudinal direction of the intermediate rafter 52D, and as shown in Figure 14, when viewed in the longitudinal direction of the intermediate rafter 52D, it is formed in a hat shape with the center in the left-right direction protruding upward like a square frame. The hat-shaped fitting 77 has a square protruding plate portion 771, a pair of horizontal extension plates 772 that extend horizontally outward in the left-right direction from both left-right ends of the square protruding plate portion 771, and multiple downward protrusions 773 (fixing members) formed by cutting out the horizontal extension plates 772.

As shown in FIG. 14, the square protruding plate portion 771 is formed in an inverted U shape with the upper part closed like a square frame and the lower part open. The square protruding plate portion 771 is arranged above the screw fixing groove portion 521b of the intermediate rafter body 521 so as to cover the upper part of the upper end of the pair of rising walls 521c that constitute the screw fixing groove portion 521b. The hat-shaped metal fitting 77 is restricted from moving in the left-right direction by the square protruding plate portion 771 being arranged so as to cover the upper part of the pair of rising walls 521c that constitute the screw fixing groove portion 521b of the intermediate rafter body 521. The upper plate 771a of the square protruding plate portion 771 is arranged between the intermediate cover member upper plate 523a of the intermediate cover member 523. A through hole 771b through which the shaft portion 532a of the cover fixing screw 532 passes is formed in the center of the longitudinal direction of the upper plate 771a.

As shown in FIG. 14, the pair of horizontal extension plates 772 are formed to extend outward in the left-right direction of the square protruding plate portion 771, and are arranged along the upper surface of the left-right end portion of the panel material 6. The pair of horizontal extension plates 772 are arranged such that their outer left-right end portions are sandwiched between the intermediate cover side gasket 524 attached to the intermediate cover side gasket fitting portion 523b and the panel material 6.

As shown in FIG. 15, three downward protrusions 773 are provided for each horizontal extension plate 772. The three protrusions 733 are arranged at the center and both end sides in the longitudinal direction of the horizontal extension plate 772. The downward protrusions 773 are formed, for example, by cutting downward in a triangular shape, by cutting out a part of the horizontal extension plate 772 into a triangular shape so that they can easily bite into the upper surface of the panel material 6.

As shown in FIG. 14, the hat-shaped metal fittings 77 restrict movement of the panel material 6 by having multiple downward projections 773 of the hat-shaped metal fittings 77 bite into the upper surface of the panel material 6. The cover fixing screws 532 fix the intermediate cover member 523 to the intermediate rafter body 521, and the multiple downward projections 773 of the hat-shaped metal fittings 77 bite into the upper surface of the panel material 6, thereby fixing the intermediate cover member 523, the panel material 6, and the hat-shaped metal fittings 77.

As a result, according to the sixth embodiment, even if pressure is applied to the upper surface of the panel material 6 due to a load such as snow accumulation, it is possible to suppress the left-right displacement of the panel material 6. Therefore, by not providing a furring strip, it is possible to improve the design while suppressing the panel material 6 from bending downwards, even without providing a furring strip.

The pair of horizontal extension plates 772 of the hat-shaped metal fitting 77 are each arranged with their outer left and right ends sandwiched between the intermediate cover side gasket 524 attached to the intermediate cover side gasket fitting portion 523b and the panel material 6. This results in a structure in which the downward protrusion 773 is pressed from above when the intermediate cover member 523 is fixed to the intermediate rafter body 521 with the cover fixing screw 532, and the force with which the downward protrusion 773 bites into the panel material 6 increases, so that the panel material 6 can be held with greater force and the panel material 6 is less likely to be pulled out.

In addition, in this embodiment, the square protruding plate portion 771 is arranged to cover the upper portion of a pair of rising walls 521c that constitute the screw fixing groove portion 521b of the intermediate rafter body 521, thereby providing a hat-shaped metal fitting 77 whose movement in the left-right direction is restricted, and the multiple downward protrusions 773 of the hat-shaped metal fitting 77 bite into the upper surface of the panel material 6, thereby fixing the intermediate cover member 523, the panel material 6, and the hat-shaped metal fitting 77. As a result, the multiple downward protrusions 773 of the hat-shaped metal fitting 77 fix the panel material 6 to the hat-shaped metal fitting 77 whose movement in the left-right direction is restricted, so that the movement of the panel material 6 in the left-right direction can be further restricted. Therefore, downward bending of the panel material 6 can be further suppressed.

Next, the seventh embodiment will be described. The seventh embodiment is a modified version of the second embodiment, and is an embodiment in which the configuration for fixing the panel material 6 is different from that of the second embodiment. The other configurations of the seventh embodiment are the same as those of the second embodiment. In the description of the configuration of the seventh embodiment, the description of the same configuration as that of the second embodiment may be omitted. Note that in the seventh embodiment, only the configuration of the intermediate rafter 57A will be described, but the configuration in which the end rafter (not shown) holds the panel material 6 is the same as the configuration in which the end rafter 56 of the second embodiment holds the panel material 6 on one side in the left-right direction of the intermediate rafter 57A. Therefore, the description of the configuration on one side in the left-right direction of the intermediate rafter 57A can be used to describe the configuration of the end rafter.

As shown in FIG. 16, the panel material 6 in the seventh embodiment is not fixed by the panel fixing screw 58 in the second embodiment, but is fixed by the panel fixing screw 81. In the seventh embodiment, the longitudinal position at which the panel material 6 is fixed by the panel fixing screw 81 in the seventh embodiment is the same as in the second embodiment.

As shown in FIG. 16, the panel fixing screw 81 is screwed in together with the spacer member 82 (regulating member) penetrating vertically on the left-right side of the intermediate rafter 57A, on the end side of the panel material 6, closer to the portion where the panel material 6 is sandwiched between the intermediate rafter side packing 576 attached to the intermediate rafter packing fitting portion 573 and the bead material 577 arranged in the bead material arrangement portion 574. The panel fixing screw 81 is inserted vertically at a position, for example, about 15 mm inward from the left-right end of the intermediate rafter 57A.

The spacer member 82 is attached to the underside of the intermediate rafter top plate 572 of the intermediate hollow portion 571 between the intermediate rafter packing fitting portion 573 in the left-right direction and the left-right central portion of the intermediate rafter 57A, and is disposed between the underside of the intermediate rafter top plate 572 of the intermediate hollow portion 571 and the upper surface of the panel material 6. The spacer member 82 is disposed in the left-right direction between the vertical extension portion 571b formed at the top of the intermediate hollow portion 571 and the intermediate rafter packing fitting portion 573. As a result, the spacer member 82 is restricted from moving in the left-right direction by the vertical extension portion 571b of the intermediate hollow portion 571 and the intermediate rafter packing fitting portion 573.

When attaching the panel fixing screw 81, as shown in FIG. 16, the panel fixing screw 81 can be screwed into a part of the underside of the intermediate rafter top plate 572, the spacer member 82, and the panel material 6 in that order to fix the intermediate rafter top plate 572, the spacer member 82, and the panel material 6. In the seventh embodiment, the intermediate rafter 57A and the panel material 6 are fixed with the panel fixing screw 81, but this is not limited to this and they may be fixed with rivets as in the second embodiment.

As a result, according to the seventh embodiment, as in the second embodiment, even if pressure is applied to the upper surface of the panel material 6 due to a load such as snow, it is possible to suppress the left-right displacement of the panel material 6. Therefore, by not providing a furring strip, it is possible to improve the design while suppressing the panel material 6 from bending downwards, even without providing a furring strip.

In addition, in this embodiment, a spacer member 82 whose movement in the left-right direction is restricted by the vertical extension portion 571b of the intermediate hollow portion 571 and the intermediate rafter gasket fitting portion 573 is provided, and the panel fixing screw 81 fixes the intermediate rafter top plate 572, the spacer member 82, and the panel material 6. As a result, the panel fixing screw 81 fixes the panel material 6 to the spacer member 82 whose movement in the left-right direction is restricted, so that the left-right movement of the panel material 6 can be further restricted. Therefore, downward bending of the panel material 6 can be further suppressed.

The above describes one preferred embodiment of the roof structure of the present disclosure, but the present disclosure is not limited to the above-described embodiment and can be modified as appropriate.

For example, in the above embodiment, the intermediate rafter and the panel material are fixed at the middle part of the intermediate rafter in the longitudinal direction by the fixing members for fixing the panel (panel fixing screws 54, 58, panel fixing rivets 71, panel fixing screws 73, 75, hat-shaped fittings 77, panel fixing screw 81), but this is not limited to this. For example, the fixing members may be used to fix the four members and the panel material at any position on any of the four members surrounding the panel material. Also, for example, the fixing members may be used to fix the intermediate rafter and the panel material at any position along the entire longitudinal length of the intermediate rafter. For example, the fixing members may be used to fix the intermediate rafter and the panel material at positions that divide the entire longitudinal length of the intermediate rafter into thirds.

In the above embodiment, the panel material may be fixed not only to the rafters, but also to the front and rear materials.
