[0003] [Patent Document 1] JP 2018-199978 A Summary of the Invention [Problem to be solved by the invention]

[0004] In some cases, it may be necessary to extend the beams to the outside of the roof body depending on the site where the roof structure is to be installed. However, when a skimmer fin is provided at the end of the roof body, if a beam extended to the outside of the roof body is used, the skimmer fin protrudes below the upper surface of the beam, causing interference between the skimmer fin and the beam. Therefore, there is a demand for a roof structure that can prevent interference between the skimmer fin and the beam.

[0005] The present disclosure aims to provide a roof structure comprising a pillar material, a beam, and a roof body placed on top of the beam, in which a drain fin is provided at the end of the roof body, and which can prevent interference between the drain fin and the beam. [Means for solving the problem]

[0006] The present disclosure relates to a roof structure comprising a pillar material, a beam connected to the pillar material, a roof body disposed on top of the beam and having a drip fin protruding downward, and a beam spacer disposed between the beam and the roof body.

[0008] Hereinafter, a first embodiment of the roof structure of the present disclosure will be described with reference to the drawings. The roof structure 1 of this embodiment can be applied to, for example, a carport. The roof structure may also be applied to structures other than carports, such as bicycle parking lots, shelters, rest areas, terraces, bus stops, and the like.

[0009] In the description of this embodiment, the direction in which the multiple rafters 43 of the roof body 4 extend is also referred to as the front-to-rear direction. In addition, in Fig. 1, the left front side of the roof structural body 1 is also referred to as the front side, and the right rear side of the roof structural body 1 is also referred to as the rear side. Also, the direction in which the beams 3 extend, which is perpendicular to the front-to-rear direction in which the rafters 43 extend, is also referred to as the left-to-right direction. In the drawings, the front side is referred to as "FRONTSIDE" and the rear side is referred to as "BACKSIDE".

[0010] First, a description will be given of the overall structure of the roof structural body 1 of this embodiment. As shown in Figures 1 to 5, the roof structural body 1 of this embodiment is a carport with a so-called double-supported structure in which a roof body 4 is supported by two pairs of support columns 2 on each of the left and right sides.

[0011] 1 to 5, the roof structural body 1 of this embodiment includes two pairs of pillars 2 (pillar members) erected on the ground 11, two beams 3 extending from the upper ends of the pillars 2 in a direction intersecting the pillars 2, a roof body 4 arranged on the upper parts of the two beams 3, a beam spacer 5 arranged between the beams 3 and the roof body 4, a plurality of beams 6 (beam members), and two vertical gutters 7. The pillars 2 and beams 3 are formed from extruded shapes of aluminum material, and have a hollow structure with a hollow cross section.

[0012] As shown in Fig. 1, the two pairs of support columns 2 are arranged side by side with a space between them in the front-to-rear direction. The pairs of support columns 2 are arranged separately on both sides in the left-right direction of the roof body 4 (the rear left side and the front right side in Fig. 1) and are connected to both ends in the left-right direction of the beam 3. The support columns 2 are formed to extend in the vertical direction.

[0013] A vertical gutter 7 is provided on each of the pair of front support pillars 2. As shown in Fig. 2, the vertical gutter 7 has a vertical portion 71 extending in the up-down direction of the pair of support pillars 2 arranged on the front side, and an inclined portion 72 connected to the upper end of the vertical portion 71 and formed with a downward inclination from the front end of the roof body 4 toward the support pillar 2.

[0014] As shown in Figs. 1 to 5, the two beams 3 are arranged spaced apart in the front-to-rear direction of the roof structural body 1. The two beams 3 each extend in the left-to-right direction of the roof structural body 1. Both left-to-right end portions of the two beams 3 (the end portions on the rear left and front right sides) are connected to the upper ends of the columns 2. A roof body 4 is arranged on the top of the two beams 3.

[0015] Of the two beams 3, the beam 31 located on the front side is located at the bottom of the roof body 4 and does not extend outward in the left-right direction of the roof body 4, as shown in Figures 1 and 2. Of the two beams 3, the beam 32 located on the rear side is located on one side of the roof body 4 in the left-right direction, extending outward from the roof body 4.

[0016] The two beams 3 are each configured with a hollow structure having a cross section formed into a square tube shape. As shown in Fig. 2 and Fig. 6, each of the two beams 3 is configured by connecting a first divided beam portion 351 and a second divided beam portion 352 via a connecting sleeve 353 (connecting member).

[0017] 6, the connecting sleeve 353 is formed in a cylindrical shape and is disposed inside the first divided beam portion 351 and the second divided beam portion 352, straddling the first divided beam portion 351 and the second divided beam portion 352. The first divided beam portion 351 and the connecting sleeve 353 are fastened by a bolt 354 (first screw member). The second divided beam portion 352 and the connecting sleeve 353 are fastened by a bolt 355 (second screw member). Heads 354a and 355a of the bolts 354 and 355 are disposed above the upper surface 3a of the beam 3.

[0018] The roof body 4 is placed on top of the two beams 3. As shown in Figures 1 and 3, the roof body 4 has a front frame 41, a rear frame 42, a plurality of rafters 43, a pair of side frames 44, a plurality of ribs 45, and a plurality of panel materials 46 (roof materials). The roof body 4 is formed with a downward slope on the front side in the front-to-rear direction.

[0019] The front frame 41 is disposed on the front side of the roof body 4 and extends in the left-right direction. The rear frame 42 is disposed on the rear side of the roof body 4 and extends in the left-right direction.

[0020] The multiple rafters 43 are each formed to extend in a direction perpendicular to the longitudinal direction of the beam 3, and thus extend in the front-to-rear direction of the roof body 4. The multiple rafters 43 are arranged side by side in the left-to-right direction of the roof body 4 and spaced apart from each other in the left-to-right direction. The multiple rafters 43 include a pair of end rafters 431 and multiple intermediate rafters 432.

[0021] 1 and 3, the multiple intermediate rafters 432 are arranged side by side in the left-right direction between the pair of end rafters 431 so as to partition the insides of the front frame 41, the rear frame 42, and the pair of end rafters 431, 431. As shown in Figures 7 and 8, the intermediate rafter 432 has a hollow frame 432a and a pair of panel holding portions 432b.

[0022] 1 and 3, a pair of end rafters 431 extend in the front-rear direction at both left-right end sides of the roof body 4. As shown in Figures 7 and 8, the end rafter 431 has a hollow frame portion 431a, a panel holding portion 431b, and an open frame portion 431c formed on the outside of the hollow frame portion 431a in the left-right direction.

[0023] At both left and right end sides of the roof body 4, a pair of side frames 44 are arranged on the left and right outer sides of the end rafters 431. As shown in Figures 7 and 8, the pair of side frames 44 each extend in the longitudinal direction of the end rafters 431. The side frames 44 are formed in a frame shape connected to the left and right outer sides of the end rafters 431 so as to cover the open portion of the open frame portion 431c of the end rafters 431.

[0024] The side frame 44 has an upper lateral protruding frame 441 formed on the upper side and protruding laterally, and a drip fin 442 formed on the lower side and protruding downward below the lower surface of the end rafter 431.

[0025] As shown in Fig. 7, above the front beam 31 of the two beams 3, the beam 31 does not extend to the outside in the left-right direction of the roof body 4, so the drain fin 442 protrudes downward from the upper surface of the front beam 31 on the outside of the left-right direction of the upper part of the beam 31. As shown in Fig. 8, above the rear beam 32 of the two beams 3, the beam 32 extends to the outside of one side in the left-right direction of the roof body 4, so that the roof body 4 is raised by the beam spacer 5 described later, and the drain fin 442 is located above the upper surface of the beam 32.

[0026] 1, the multiple ribs 45 are arranged between adjacent rafters 43 of the multiple rafters 43. The multiple ribs 45 are arranged side by side between the adjacent rafters 43 at a distance in the front-rear direction and extend in the left-right direction. Each of the multiple ribs 45 is connected to an adjacent rafter 43.

[0027] Inside the front frame 41, the rear frame 42 and the pair of end rafters 431, 431, in the portion partitioned by the multiple intermediate rafters 432, panel materials 46 (face materials) are attached in a line in the longitudinal direction of the beam 3. The panel materials 46 have their undersides supported by multiple middle ribs 45.

[0028] A configuration in which the roof body 4 is disposed on the upper parts of the front beam 31 and the rear beam 32 will be described. First, a configuration in which the roof body 4 is disposed on the upper part of the front beam 31 will be described. As shown in Figures 2, 7 and 13, a plurality of beams 6 are disposed on the upper part of the front beam 31. The plurality of beams 6 are disposed between the front beam 31 and the intermediate rafters 432 of the roof body 4. The plurality of beams 6 have a predetermined width in the width direction of the beam 31, and extend a predetermined length in the longitudinal direction of the beam 31, as shown in Figure 14.

[0029] 7, the multiple beams 6 are not arranged under the intermediate rafters 432 on both end sides in the left-right direction of the roof body 4 in the front beam 31, but one beam 6 of height H1 is arranged inside it, and multiple beams 6 of height H2 are arranged side by side on the left and right inside the one beam 6 of height H1. By making the height H2 of the central beam 6 higher than the height H1 of the beam 6 on the end sides, it is possible to prevent the central side of the roof body 4 from bending downward in the left-right direction even if the central side of the beam 31 bends downward in the left-right direction.

[0030] 9 and 10, a pair of beam-upper-side locking portions 33 are formed on the upper surface 31a (upper portion) of the beam 31. The pair of beam-upper-side locking portions 33 are arranged spaced apart in the width direction on the upper surface 31a of the beam 31, as shown in FIG. 13, and are formed in a groove shape extending in the longitudinal direction of the beam 31.

[0031] As shown in Fig. 10, a bundle lower side locking portion 61 is formed at the lower part of the bundle 6. The bundle lower side locking portion 61 is formed in a convex shape that protrudes downward and extends in the longitudinal direction of the beam 3. The bundle lower side locking portion 61 is locked to the beam upper side locking portion 33 of the beam 31. In this state, as shown in Fig. 14, in the portion of the beam 31 where the bundle 6 is located, the intermediate rafter 432, the bundle 6, and the beam 31 are fastened together and fixed with screws.

[0032] In this way, at the front side of the roof body 4, with multiple beams 6 interposed between the front beam 31 and the roof body 4, the intermediate rafters 432, the beams 6 and the beams 31 are fastened together and fixed with screws, and the roof body 4 is positioned on top of the front beam 31.

[0033] Next, a configuration in which the roof body 4 is disposed on the upper part of the rear beam 32 will be described. As shown in Figs. 2, 8 and 13, a beam spacer 5 is disposed on the upper part of the rear beam 32. The beam spacer 5 is disposed between the rear beam 3 and the roof body 4. The beam spacer 5 extends along the longitudinal direction of the beam 3. As shown in Fig. 2, the beam spacer 5 extends between the beam 3 and the roof body 4 over the entire area of ​​the roof body 4 in the left-right direction.

[0034] 11 and 12, a pair of beam-upper-side locking portions 33 are formed on the upper surface 32a (upper portion) of the beam 32. The pair of beam-upper-side locking portions 33 are arranged spaced apart in the width direction on the upper surface 32a of the beam 32, as shown in FIG. 13, and are formed in a groove shape extending in the longitudinal direction of the beam 32.

[0035] As shown in Figures 11 and 12, the beam spacer 5 has, in cross-section, a hollow spacer body 51, a pair of spacer upper side engagement portions 52 formed on the upper surface (upper portion) of the spacer body 51, a pair of lower leg portions 53 protruding downward from both widthwise ends of the spacer body 51, and a lower recess 54 (recess) formed in the lower portion of the spacer body 51.

[0036] As shown in FIG. 15, the pair of spacer upper side locking portions 52 are disposed on the upper surface 5a of the beam spacer 5 so as to be spaced apart in the width direction, and are formed in the shape of a recessed groove extending in the longitudinal direction of the beam 32.

[0037] 11 and 12, the pair of lower legs 53 are disposed spaced apart in the width direction of the beam 32. Each of the pair of lower legs 53 is formed in an inverted T shape in cross section. The lower leg 53 has a vertical plate portion 531 extending downward from both ends of the spacer body 51 in the width direction, and a horizontal plate portion 532 formed at the lower end of the vertical plate portion 531.

[0038] The pair of horizontal plate portions 532 are disposed on the upper surface of the beam 32, spaced apart in the width direction of the beam 32. The horizontal plate portion 532 has a predetermined width in the width direction of the beam 32, and extends in the longitudinal direction of the beam 32. A spacer lower side locking portion 532a is formed at the lower end of each of the pair of horizontal plate portions 532 on the inner side in the width direction of the beam spacer 5. The spacer lower side locking portion 532a is formed in a convex shape protruding downward at the lower portion of the beam spacer 5, and extends in the longitudinal direction of the beam 32. The spacer lower side locking portion 532a is locked to the beam upper side locking portion 33 of the beam 32.

[0039] The lower recess 54 is formed below the center in the width direction of the beam spacer 5, between the pair of lower legs 53, so as to recess from the lower side to the upper side. The lower recess 54 recesses from the lower side to the upper side so as to avoid the head 354a of the bolt 354 fastening the first divided beam portion 351 and the connecting sleeve 353, and the head 355a of the bolt 355 fastening the second divided beam portion 352 and the connecting sleeve 353.

[0040] 2, 8 and 13, a plurality of bundles 6 are arranged on the upper part of the beam spacer 5. The plurality of bundles 6 are arranged between the beam spacer 5 and the intermediate rafter 432 of the roof body 4. The plurality of bundles 6 have a predetermined width in the width direction of the beam 3, and extend a predetermined length in the longitudinal direction of the beam 3, as shown in FIG.

[0041] 8, the multiple beams 6 are not arranged under the intermediate rafters 432 on both end sides in the left-right direction of the roof body 4 on the upper surface of the beam spacer 5, but one beam 6 of height H1 is arranged inside it, and multiple beams 6 of height H2 are arranged side by side inside the one beam 6 of height H1. By making the height H2 of the central beam 6 higher than the height H1 of the beam 6 on the end sides, it is possible to prevent the central side of the roof body 4 in the left-right direction from bending downward even if the central side of the beam 32 bends downward in the left-right direction.

[0042] 12, a bundle lower side locking portion 61 is formed at the bottom of the bundle 6. The bundle lower side locking portion 61 is formed in a convex shape that protrudes downward and extends in the longitudinal direction of the beam 3. The bundle lower side locking portion 61 is locked to a spacer upper side locking portion 52 formed at the top of the beam spacer 5. In this state, as shown in FIG. 16, in the portion of the beam spacer 5 where the bundle 6 is placed, the intermediate rafter 432, the bundle 6, and the beam spacer 5 are fastened together and fixed with screws.

[0043] Here, in the embodiment, the bundle lower side locking portion 61 formed at the lower part of the bundle 6 is configured to be lockable with the spacer upper side locking portion 52 formed at the upper part of the beam spacer 5, and is also configured to be lockable with the beam upper side locking portion 33 formed at the upper part of the beam 32. As a result, as shown in Fig. 12, when the beam spacer 5 is provided at the upper part of the beam 32, the bundle 6 can be arranged at the upper part of the beam spacer 5, and as shown in Fig. 10, even when the beam spacer 5 is not provided at the upper part of the front beam 31, for example, the bundle 6 can be arranged at the upper part of the beam 31.

[0044] In this way, at the rear of the roof body 4, a beam spacer 5 is positioned on the upper part of the rear beam 32, and with multiple beams 6 interposed between the beam spacer 5 and the roof body 4, the intermediate rafter 432, the beams 6 and the beam spacer 5 are fastened together and fixed with screws, and the roof body 4 is positioned on the upper part of the rear beam 32.

[0045] The roof structure 1 constructed as above can avoid interference between the skidding fins 442 of the side frames 44 and the beams 32 by placing the beam spacers 5 between the roof body 4 and the beams 32 and raising the bottom of the roof body 4. Furthermore, since the roof structure 1 has a structure in which the roof body 4 is connected by fixing a plurality of rafters 43 to the beam spacers 5 as shown in Fig. 13, the roof body 4 can be easily moved to any position in the longitudinal direction of the beams 3 by simply moving the attachment position of the beam spacer 5 along the longitudinal direction of the beams 32 with the plurality of rafters 43 arranged side by side on the beam spacer 5 and fixed thereto.

[0046] The roof structure 1 of this embodiment described above provides the following effects. The roof structure 1 of this embodiment includes the pillars 2, the beams 32 connected to the pillars 2, the roof body 4 arranged on the upper part of the beams 32 and having a drip fin 442 protruding downward, and the beam spacer 5 arranged between the beams 32 and the roof body 4.

[0047] As a result, when the beam 32 is extended in the longitudinal direction, the beam spacer 5 is placed between the beam 32 and the roof body 4 to raise the bottom of the roof body 4, thereby preventing the water cutter fins 442 of the side frames 44 from interfering with the beam 32. Also, by configuring the beam spacer 5 as a separate member from the roof body 4 and the beam 3, it is possible to attach it to the beam 32 that is normally used to raise the bottom of the roof body 4. As a result, when the beam 32 is extended, the beam spacer 5 can easily prevent interference between the water cutter fins 442 of the side frames 44 and the beam 32 while reducing costs.

[0048] In this embodiment, the beam spacer 5 extends along the longitudinal direction of the beam 32. Therefore, with a plurality of rafters 43 aligned and fixed to the beam spacer 5, the roof body 4 can be easily moved to any position in the longitudinal direction of the beam 32 simply by moving the mounting position of the beam spacer 5 along the longitudinal direction of the beam 3.

[0049] In this embodiment, a beam upper side locking portion 33 is formed on the upper portion of the beam 32, and a spacer lower side locking portion 532a that can be locked to the beam upper side locking portion 33 is formed on the lower portion of the beam spacer 5. Therefore, when the beam spacer 5 is disposed on the upper portion of the beam 32, lateral displacement of the beam spacer 5 in the width direction of the beam 32 can be suppressed. As a result, the beam spacer 5 is less likely to fall off the beam 32 during construction. This improves workability.

[0050] In this embodiment, the beam upper side locking portion 33 is formed in a groove shape extending in the longitudinal direction of the beam 32, and the spacer lower side locking portion 532a is formed in a convex shape extending in the longitudinal direction of the beam 3. This makes it possible to suppress lateral displacement of the beam 32 in the beam spacer 5 in the width direction with a simple configuration.

[0051] In this embodiment, the beam spacer 5 is provided with a bundle 6 arranged between the beam spacer 5 and the roof body 4, and the upper part of the beam spacer 5 is formed with a spacer upper side locking portion 52, and the lower part of the bundle 6 is formed with a bundle lower side locking portion 61 that can be locked to the spacer upper side locking portion 52. Therefore, when the bundle 6 is arranged on the upper part of the beam spacer 5, lateral displacement of the bundle 6 in the width direction of the beam 32 can be suppressed. As a result, the bundle 6 is less likely to fall off the beam spacer 5 during construction. This improves workability.

[0052] In this embodiment, the spacer upper side locking portion 52 is formed in a groove shape extending in the longitudinal direction of the beam 32, and the bundle lower side locking portion 61 is formed in a convex shape extending in the longitudinal direction of the beam 32. This makes it possible to suppress lateral displacement of the beam 32 in the bundle 6 in the width direction with a simple configuration.

[0053] In this embodiment, the bundle lower side locking portion 61 is configured to be lockable with the beam upper side locking portion 33 formed on the upper portion of the beam 3, and is also configured to be lockable with the spacer upper side locking portion 52 formed on the upper portion of the beam spacer 5. This allows the bundle 6 to be placed on the upper portion of the beam spacer 5 when the beam spacer 5 is provided on the upper portion of the beam 32, and allows the bundle 6 to be placed on the upper portion of the beam 31 even when, for example, the beam spacer 5 is not provided on the upper portion of the front beam 31.

[0054] In this embodiment, the heads 354a, 355a of the bolt 354 fastening the first split beam portion 351 and the connecting sleeve 353 and the bolt 355 fastening the second split beam portion 352 and the connecting sleeve 353 are both arranged above the upper surface of the beam 32, and the beam spacer 5 has a lower recess 54 recessed from the lower side to the upper side so as to avoid the heads 354a, 355a of the bolts 354, 355. Therefore, the lower recess 54 can avoid the heads 354a, 355a of the bolts 354, 355. As a result, when the beam spacer 5 is installed on the upper part of the beam 32, the heads 354a, 355a of the bolts 354, 355 do not get in the way, so that the beam spacer 5 can be easily installed on the upper part of the beam 32.

[0055] A second embodiment will be described. In the description of the second embodiment, differences from the first embodiment will be described.

[0056] The roof structural body 1A of the second embodiment has a configuration in which two roof bodies 4A, 4B are connected together, as shown in Figures 17 and 18. The roof structural body 1A includes two pairs of posts 2 (pillar members) erected on the ground 11, two beams 3 extending from the upper ends of the posts 2 in a direction intersecting the posts 2, two roof bodies 4A, 4B arranged on the upper parts of the two beams 3, a beam spacer 5 arranged between the beams 3 and the roof bodies 4A, 4B, and a plurality of beams 6.

[0057] The two beams 3 extend in the left-right direction across the two roof bodies 4A, 4B. The two roof bodies 4A, 4B are disposed above the two beams 3.

[0058] The two roof bodies 4A, 4B have a first roof body 4A arranged on one side in the left-right direction and an other roof body 4B arranged on the other side in the left-right direction. The two roof bodies 4A, 4B are connected to the left and right while being shifted forward and backward. The side frames 44 of the two roof bodies 4A, 4B are connected to each other by a side frame connecting member 47.

[0059] 19, the side frame connecting member 47 has an upper connecting member 471 and a lower connecting member 472. The upper connecting member 471 and the lower connecting member 472 connect the upper lateral protruding frames 441 of the side frames 44 by sandwiching them together.

[0060] The two roof bodies 4A, 4B are disposed on top of the two beams 3, respectively. Both of the two beams 3 extend in the left-right direction across the two roof bodies 4A, 4B. The two beams 3 extend in the longitudinal direction below the side frame connecting member 47 at the connecting portion of the two roof bodies 4A, 4B. The two beams 3 extend outward in the left-right direction at one end side of the one-side roof body 4A, and extend outward in the left-right direction at the other end side of the other-side roof body 4B.

[0061] In the second embodiment, a beam spacer 5 similar to that in the first embodiment is arranged on each of the upper portions of the two beams 3, and a plurality of beams 6 similar to that in the first embodiment are arranged on the upper portions of the beam spacers 5. As a result, when the beams 3 are extended in the longitudinal direction outside the left-right direction of the roof structure 1, the bottoms of the roof bodies 4A and 4B are raised as in the first embodiment, so that the drip fins 442 can be prevented from interfering with the beams 3. Also, when the beams 3 extend in the longitudinal direction at the connecting portion of the two roof bodies 4A and 4B, the bottoms of the roof bodies 4A and 4B are raised, so that the drip fins 442 can be prevented from interfering with the beams 3.
