[0003] [Patent Document 1] JP 2013-213320 A Summary of the Invention [Problem to be solved by the invention]

[0004] The roof of the carport described in Patent Document 1 is composed of a frame and a panel material, so the unevenness of the frame and the panel material is visible from the outside. Therefore, it is desirable to improve the design. In addition, the carport described in Patent Document 1 has a hanging structure in which the roof is suspended by a hanging device between the beam and the roof, so the beam protrudes significantly upward when viewed from below, so it is desirable to make the roof structure compact and improve the design. In addition, in roof structures such as carports, the roof body may be sloped to guide rainwater that runs along the top surface of the roof body. In such cases, it is necessary to improve the drainage performance of the roof structure.

[0005] An object of the present invention is to provide a roof structure that can improve design and drainage performance with a simple configuration. [Means for solving the problem]

[0006] The present invention relates to a roof structure (for example, a carport 1 described below) comprising a pillar material (for example, a support 2 described below), a beam (for example, a beam 3 described below) connected to the pillar material, and a roof body (for example, a roof body 4 described below) directly or indirectly connected to the beam, the roof body having a plurality of long materials (for example, a long material 41 described below) arranged in a predetermined direction, the roof body having a flat lower surface (for example, a lower surface 4b described below) and a concave gutter structure (for example, a roof body side gutter structure 40 described below) on at least a portion of an upper surface (for example, an upper surface 4a described below).

[0007] It is also preferable that the roof body is constructed so that at least a portion of it includes a plurality of long members each having the gutter structure.

[0008] It is also preferable that the roof body is constructed including a plurality of long members, at least in part of which has the gutter structure and a hollow structure in which a hollow portion is formed.

[0009] In addition, it is preferable that the upper surface of the roof body is provided with portions which are directly or indirectly connected to the beams (for example, the upper inward extension piece 423 on one side, the upper inward extension piece 443 on the other side, and the upper outward extension pieces 427, 437 on the other side, which will be described later), and that the roof body is arranged below the beams and hung directly or indirectly from the beams.

[0010] It is also preferable that the upper surface of the roof body is directly connected to the beam.

[0011] It is also preferable that the roof body be inclined downward from one side to the other side in the longitudinal direction of the elongated material.

[0012] It is also preferable that the long member is formed from an aluminum shaped member and has a hollow structure having a hollow portion at least in a part thereof. Effect of the Invention

[0013] According to the present invention, it is possible to provide a roof structure that can improve the design and has improved drainage performance with a simple configuration. [Brief description of the drawings]

[0017] In the description of this embodiment, the direction in which the multiple long members (long members) 41 constituting the roof body 4 of the carport 1 extend is also referred to as the front-rear direction (the longitudinal direction of the long members 41). In addition, in FIG. 1, the left front side of the carport 1 is also referred to as the front side, and the right rear side of the carport 1 is also referred to as the rear side. In this embodiment, the roof body 4 is inclined in the front-rear direction, and the front-rear direction of the roof body 4 is also referred to as the inclination direction, the left front side in FIG. 1 is also referred to as the downstream side, and the right rear side in FIG. 1 is also referred to as the upstream side. In addition, the direction in which the beams 3 extend and which is perpendicular to the front-rear direction in which the long members (long members) 41 extend is also referred to as the left-right direction (the direction intersecting the longitudinal direction of the long members 41).

[0018] First, the overall structure of the carport 1 of this embodiment will be described. As shown in Figures 1 to 3, the carport 1 of this embodiment is a so-called double-supported carport in which a roof body 4 is supported on each of the left and right sides by a pair of support columns 2. The carport 1 of this embodiment is also configured as a suspended structure in which the roof body 4 is suspended and connected to the lower part (lower part) of the beams 3 connected to the support columns 2.

[0019] As shown in Figures 1 to 3, the carport 1 of this embodiment includes two pairs of support columns 2 (pillar members) erected on the ground 11, two beams 3 extending from the upper ends of the support columns 2 in a direction intersecting the support columns 2, a roof body 4 arranged below the two beams 3, a roof body downstream gutter structure 45 arranged at the end of the front side (downstream side in the tilt direction) in the front-to-rear direction of the roof body 4, a pair of lower side inclined gutter structures 46 connected to the lower part of the roof body downstream gutter structure 45, a roof body upstream end cover member 8, and multiple roof body downstream end cover members 9. The support columns 2 and the beams 3 are formed of extruded shapes of aluminum material, and have a hollow structure with a hollow section in cross section.

[0020] 1 to 3, two pairs of support columns 2 (pillar members) are arranged side by side in the front-to-rear direction. The pair of support columns 2 are arranged on both left-right sides of the carport 1, facing each other with the roof body 4 in between, and are connected to both left-right ends of the beams 3.

[0021] As shown in Fig. 1, the two pairs of pillars 2 are arranged spaced apart in the front-rear direction of the carport 1. The pillars 2 are formed to extend in the vertical direction. As shown in Fig. 1, the pillars 2 have a hollow pillar main body 21 whose cross section is formed into a rectangular tube shape, and a pair of cover mounting walls 22 that protrude from the side surface of the pillar main body 21 facing the roof body 4 toward the roof body 4 and extend in the vertical direction. A pillar cover member 23 is attached to the pair of cover mounting walls 22. A pillar cap 24 is arranged on the upper end of the pillar 2 so as to cover the opening at the upper end of the pillar 2.

[0022] As shown in Figures 4 and 5, water discharged from a downward inclined gutter structure 46 (described later) flows between the pillar 2 and the pillar cover member 23. Since water discharged from a downward inclined gutter structure 46 (described later) flows into and between the pillar 2 and the pillar cover member 23, the pillar 2 and the pillar cover member 23 are configured as a pillar side gutter component 20 (pillar side gutter structure) as shown in Figure 6.

[0023] As shown in Fig. 1, the two beams 3 are arranged spaced apart in the front-to-rear direction of the carport 1. The two beams 3 each extend in the left-to-right direction of the roof body 4. Both left-to-right ends (right and left ends) of the two beams 3 are connected to the upper ends of the pillars 2 via L-shaped connecting members 25, as shown in Fig. 5. The roof body 4 is connected to the lower parts of the two beams 3.

[0024] 1 and 4, each of the two beams 3 has a beam-side hollow portion 31 formed in a rectangular cylindrical cross section, and an extension plate portion 32. In this embodiment, the two beams 3 are disposed facing each other with a space therebetween in the front-to-rear direction of the roof body 4, and the configurations of the opposing surfaces of the beams 3 (the surfaces of the beams 3 facing the opposing other beam 3) are the same.

[0025] The extending plate portion 32 extends from the lower end of the beam side hollow portion 31 toward the center side of the roof body 4 in the front-to-rear direction (the side of the beam 3 other than the beam 3 of a pair of beams 3) and is formed in the shape of a plate extending in the left-right direction.

[0026] As shown in Figs. 4 and 5, the extending plate portion 32 is fixed to the roof body 4 at the extending plate portion 32 by a plurality of screw members 101 arranged side by side in the left-right direction.

[0027] 1, the roof body 4 has a hanging structure in which the roof body 4 is hung from the lower parts of two beams 3, and is attached (connected) to the lower parts of the two beams 3. The roof body 4 is composed of a plurality of long members (long members) 41 that are arranged side by side in the direction in which the beams 3 extend and are fitted and connected to each other.

[0028] As shown in Fig. 3, the upper surface 4a of the roof body 4 is formed in a downward inclination, for example, at an inclination angle α in the front-to-rear direction of the roof body 4, with the front side in the front-to-rear direction descending (inclined downward from one side to the other in the longitudinal direction of the long member 41). Therefore, the front side in the front-to-rear direction of the roof body 4 is the downstream side of the flow of water flowing on the upper surface 4a of the roof body 4. In this embodiment, for example, the inclination angle α in the front-to-rear direction of the roof body 4 is set to about 1° to 2°. Moreover, the upper surface 4a of the roof body 4 is not inclined in the left-to-right direction.

[0029] 1 and 4, the multiple long members 41 each extend in the front-to-rear direction of the carport 1 (a direction perpendicular to the direction in which the beams 3 extend). Each of the multiple long members 41 is formed of an extruded aluminum material. Each of the multiple intermediate gutter constituent members 43 among the multiple long members 41 has a hollow structure having a hollow portion whose cross section is formed to be hollow.

[0030] The roof body 4 has, on a part of its upper surface 4a, a plurality of concave roof body side gutter structures 40 (gutter structures) extending in the longitudinal direction of the long member 41. The lower surface 4b of the roof body 4 is formed flat (planar). In this embodiment, the upper surface 4a of the roof body 4 conceptually includes, as shown in FIG. 5, the upper surface of an end side solid gutter constituent portion 421 of the one end side gutter constituent shape member 42 described later, the upper surface of an intermediate solid gutter constituent portion 432 of the intermediate gutter constituent shape member 43, the upper surface of an intermediate hollow portion 431 of the intermediate gutter constituent shape member 43, and the upper surface of an end side solid gutter constituent portion 441 of the other end side gutter constituent shape member 44.

[0031] The multiple concave roof body gutter structures 40 are formed concavely on the upper surface 4a of the roof body 4, and extend in the longitudinal direction of the elongated members 41. The multiple concave roof body gutter structures 40 are formed concavely on the upper surfaces of the multiple elongated members 41, respectively. The roof body 4 is constructed by connecting a plurality of long members 41 each having a concave roof body side gutter structure 40. In addition, in the portion where a plurality of intermediate gutter constituent members 43 are connected (at least a portion of the roof body 4), the roof body 4 is constructed by connecting a plurality of intermediate gutter constituent members 43 each having a concave roof body side gutter structure 40 and a hollow structure in which a hollow portion is formed.

[0032] In this embodiment, the concave roof body gutter structures 40 are formed on all of the upper surfaces of the multiple long members 41. The multiple concave roof body gutter structures 40 are arranged side by side in the left-right direction of the roof body 4. In the multiple concave roof body gutter structures 40, water flowing over the upper surface 4a of the roof body 4 flows from the upstream side to the downstream side (from the rear side to the front side in the front-to-rear direction) along the longitudinal direction of the long members 41.

[0033] The ratio (%) of the total length, which is the sum of the lengths of the concave roof body side gutter structures 40 in the left-right direction relative to the length of the lower surface 4b of the roof body 4 in the left-right direction (the direction perpendicular to the longitudinal direction of the long material 41) (hereinafter also referred to as the "ratio of roof body side gutter structures 40"), is appropriately set in consideration of drainage performance based on the overall balance of the structure of the roof body 4. When water is made to flow into the roof body side gutter structure 40, the ratio (%) of the roof body side gutter structure 40 is preferably, for example, about 20% or more. Also, considering that dirt (for example, fallen leaves) also flows together with rainwater when it flows, it is preferable that about half or more of the width (for example, 150 mm) of the long material 41 is the roof body side gutter structure 40, and the ratio (%) of the roof body side gutter structure 40 is preferably, for example, about 50% or more.

[0034] In this embodiment, a plurality of concave roof body gutter structures 40 are formed on the upper surface 4a of the roof body 4. Therefore, the bottom surfaces of the plurality of concave roof body gutter structures 40 are located below the lower ends of the beams 3. This allows water flowing on the upper surface 4a of the roof body 4 to flow along the inclined surface of the roof body 4 below the beams 3 without passing through the portion where the beams 3 are arranged. The plurality of concave roof body gutter structures 40 allow water flowing through the roof body 4 and dirt washed away by the water (e.g., fallen leaves, etc.) to pass through, and flow the water and dirt washed away by the water from the upstream side to the downstream side in the front-to-rear direction of the roof body 4.

[0035] In the following description of the long member 41, when it is necessary to distinguish between the left and right directions, the right side in Figs. 5 to 7 etc. will be referred to as one side, and the left side in Figs. 5 to 7 etc. will be referred to as the other side.

[0036] The multiple long members 41 constituting the roof body 4 are arranged side by side in the left-right direction as shown in Figures 5 to 7, and are composed of a one-end gutter component shape member 42 arranged at an end on one side, an other-end gutter component shape member 44 arranged at an end on the other side, and multiple intermediate gutter component shapes 43 arranged in the left-right direction between the one-end gutter component shape member 42 and the other-end gutter component shape member 44. Each of the multiple long members 41 is connected to the beams 3.

[0037] As shown in FIG. 5, the one-end gutter component shape member 42 and the other-end gutter component shape member 44 are long-length shapes arranged at one end or the other end of the long-length shapes 41 in the direction in which the long-length shapes 41 are arranged, and are arranged in parallel at the one end or the other end of the long-length shapes 41 in the direction in which the long-length shapes 41 are arranged in the roof body 4. The one-end gutter component shape member 42 and the other-end gutter component shape member 44 are formed of solid members that do not have a hollow portion, and are formed of long-length shapes whose upper side opens upward. As a result, the one-end gutter component shape member 42 and the other-end gutter component shape member 44 are formed as roof body end gutter structures 40a, 40c that are concavely recessed from the upper surface 4a of the roof body 4. The roof body end gutter structures 40a, 40c are formed by extending along the longitudinal direction of the long-length shapes 41 (the one-end gutter component shape member 42 and the other-end gutter component shape member 44).

[0038] The intermediate gutter forming members 43 are arranged in a line between the one end side gutter forming member 42 and the other end side gutter forming member 44 in the left-right direction of the roof body 4. The intermediate gutter forming members 43 are formed of a member having an intermediate solid gutter forming portion 432 of a solid middle stage gutter portion 434 that is open at the top, and an intermediate hollow portion 431 of the hollow intermediate gutter forming member 43. In this way, the intermediate gutter forming member 43 has a hollow structure having a hollow portion in a part. The intermediate gutter forming member 43 is formed as a concave roof body intermediate gutter structure 40b that is concave from the upper surface 4a of the roof body 4. The roof body intermediate gutter structure 40b is formed by extending in the longitudinal direction of the long member 41 (the intermediate gutter forming members 43).

[0039] 5, one side portion in the left-right direction of the gutter component shape member 42 at one end of the long extrusion 41 and the extension plate portion 32 of the beam 3 are fixed with a screw member 102 out of a plurality of screw members 101. In addition, the other side portion in the left-right direction of the gutter component shape member 42 at one end of the long extrusion 41 and the extension plate portion 32 of the beam 3 are fixed with a screw member 103 out of the plurality of screw members 101. The other side portion of the intermediate gutter configuring member 43 in the long member 41 and the extension plate portion 32 of the beam 3 are fixed together by a screw member 103 out of the plurality of screw members 101 . The other left-right side portion of the one-end side gutter constituent shape member 42 in the long shape member 41 and the extension plate portion 32 of the beam 3 are fixed by a screw member 104 out of the plurality of screw members 101 .

[0040] As shown in Fig. 6, the one-end side gutter component member 42 has a solid end side solid gutter component part 421 that is open upward and formed on one side in the left-right direction of the roof body 4, an other-side upper outward extending piece 427 (connected part) formed on the other side in the left-right direction of the roof body 4, and an other-side lower outer piece 428 formed on the other side in the left-right direction of the roof body 4.

[0041] The end side solid gutter component 421 has a gutter component main body 422 which is roughly U-shaped and concave and open at the top, a one side upper inward extending piece 423 (the connected part) which is arranged on one side in the left-right direction of the roof body 4, the other side upper inward extending piece 424, a drain fin 425, one side end wall 426a, and one side upper wall 426b.

[0042] The gutter forming body 422 receives water that has flowed toward the support pillars 2 on the upper surface 4a of the roof body 4 from an open portion at the top. A one-side end wall 426a is erected on one side surface of the gutter forming body 422 in the left-right direction.

[0043] 6, the one-side upper inward extending piece 423 protrudes to the other side from an upper end of one-side end wall 426a of the end-side solid gutter configuring part 421 on one side of the end-side solid gutter configuring part 421. The extending plate part 32 of the beam 3 is disposed on the upper surface of the one-side upper inward extending piece 423. The extending plate part 32 of the beam 3 and the one-side upper inward extending piece 423 are fastened together by a screw member 102.

[0044] The other-side upper inward extending piece 424 protrudes inward from the upper end of the end-side solid gutter configuring part 421 on the other side opposite to one side in the width direction of the end-side solid gutter configuring part 421. A hook protruding piece 424a protruding downward is formed at one end of the other-side upper inward extending piece 424.

[0045] When attaching the one-end gutter component shape member 42 to the beam 3, the hooking protruding piece 424a of the one-end gutter component shape member 42 can be hooked onto the rising plate 110d of the hook portion 110 fixed to the underside of the extending plate portion 32 of the beam 3, thereby temporarily placing the one-end gutter component shape member 42 on the underside of the extending plate portion 32 of the beam 3. Furthermore, with the hooking protruding piece 424a of the one-end gutter component shape member 42 hooked onto the rising plate 110d of the hook portion 110 fixed to the underside of the extending plate portion 32 of the beam 3, the one-end gutter component shape member 42 can be placed in the attachment position by rotating the one-end gutter component shape member 42 about the hooking protruding piece 424a.

[0046] As shown in Figure 6, the hook portion 110 has an attachment plate 110a fixed to the underside of the extension plate portion 32 of the beam 3 by screw member 105, a vertical extension plate 110b extending downward from the other end of the attachment plate 110a, a bottom plate 110c extending to the other side from the lower end of the vertical extension plate 110b, and a rising plate 110d rising from the other end of the bottom plate 110c.

[0047] The hooking protrusion 424a of the one-end gutter constituent shape member 42 is disposed above the hook portion 110 when the one-end gutter constituent shape member 42 is fixed to the beam 3. As a result, even if the screw members 102, 103 that secure the one-end gutter constituent shape member 42 come loose when the one-end gutter constituent shape member 42 is fixed to the beam 3, the hooking protrusion 424a can be hooked onto the rising plate 110d of the hook portion 110 to prevent the one-end gutter constituent shape member 42 from falling.

[0048] The drip fin 425 protrudes downward from the lower end of the gutter configuring part main body 422 on one side of the roof body 4 in the gutter configuring part main body 422. The drip fin 425 falls below the roof body 4 so as not to wrap around the underside 4b of the roof body 4.

[0049] The one-side upper wall 426b is formed standing from the upper end of the one-side end wall 426a (upper surface 4a of the roof body 4) at one end of the roof body 4. The one-side upper wall 426b reduces water splashing out at the one end of the roof body 4.

[0050] The other-side upper outward extending piece 427 extends from the upper end of the gutter configuring body 422 on the other side in the left-right direction of the roof body 4 (the left side in FIG. 6) toward the other side in the left-right direction. The other-side upper outward extending piece 427 is disposed at the upper end of the other end of the one-end side gutter configuring shape member 42 in the left-right direction, and constitutes a fixed part (connected part) that is fixed to the extending plate part 32 of the beam 3 by the screw member 103. The other-side upper outward extending piece 427 is formed above the hook engagement part 428a of the intermediate gutter configuring shape member 43.

[0051] At the end of the other side in the left-right direction of the roof body 4 (the left side in FIG. 6) of the other-side upper outward extending piece 427, a lateral extending wall 427b extending laterally and a downward extending wall 427c are formed.

[0052] A bead material 401 (water-stopping material) attached to one end of the adjacent intermediate gutter-constituting shape member 43 is pressed against the other surface of the downward extending wall 427c in the left-right direction of the roof body 4. The bead material 401 functions as a water-stopping section arranged at the connection portion between the one-end side gutter-constituting shape member 42 and the intermediate gutter-constituting shape member 43. The bead material 401 is formed so as to extend in the direction in which the connection portion of the one-end side gutter-constituting shape member 42 and the adjacent intermediate gutter-constituting shape member 43 (long shape member 41) extends, i.e., along the long length direction (lengthwise direction) of the long shape member 41.

[0053] The other-side lower outer piece 428 extends to the other side from the lower end portion of the gutter configuring portion main body 422 on the other side in the left-right direction of the roof body 4. A hook engagement portion 428a protruding upward is formed at the other end portion of the other-side lower outer piece 428.

[0054] 6, the hook engagement portion 428a is formed at the lower end of the one-end side gutter constituent shape member 42 at the other left-right end of the one-end side gutter constituent shape member 42 attached to the beam 3. The hook engagement portion 428a rises upward from the other-side lower outer piece 428 arranged at the lower end of the one-end side gutter constituent shape member 42 at the other left-right end of the one-end side gutter constituent shape member 42 attached to the beam 3, and is formed in a T-shape extending in the width direction perpendicular to the longitudinal direction at the rising upper end.

[0055] The hook engagement portion 428a of the intermediate gutter constituent shape member 43 is engageable with a lower protruding piece 436 on one side protruding to one side from the side surface of the lower end portion on one side of an adjacent intermediate gutter constituent shape member 43, and with a hook piece 435b of a hook extension piece 435 formed on an end portion on one side of an adjacent intermediate gutter constituent shape member 43 (described later).

[0056] Water that overflows from the middle gutter component 410 (water stop section) of the intermediate gutter component shape member 43 of the adjacent long member 41 flows onto the upper surface of the other side lower outer piece 428. The upper surface of the other side lower outer piece 428 forms the lower gutter component 420 located at the lower level in the vertical direction inside the roof body 4. The lower gutter component 420 has a gutter function to drain water and also functions as a water stop section. The lower gutter component 420 receives water that passes through the bead material 401, is received by the middle gutter component 410, and overflows from the middle gutter component 410 (water stop section). The lower gutter component 420 allows water that overflows from the middle gutter component 410 and is received to flow to both ends in the front-to-rear direction.

[0057] That is, the roof body 4 has a two-stage gutter structure at the connecting portion of adjacent long members 41, as shown in Fig. 6, with a middle gutter component 410 that is arranged on the upper side and receives water on the upper side, and a lower gutter component 420 that is arranged on the lower side and receives water that overflows from the middle gutter component 410 on the lower side. The middle gutter component 410 and the lower gutter component 420 extend in the direction in which the connecting portion of adjacent long members 41 extends, i.e., along the long direction (lengthwise direction) of the long members 41.

[0058] As shown in FIG. 6, the one-end side gutter constituent shape member 42 is fastened together with the extension plate portion 32 of the beam 3 on one side in the left-right direction of the roof body 4 by a screw member 102 moved from above. In addition, the one-end side gutter constituent shape member 42 has the other-side upper outward extending piece 427 fastened together with the extending plate portion 32 of the beam 3 by a screw member 103 moved from above on the other side in the left-right direction of the roof body 4.

[0059] As shown in Figure 7, multiple intermediate gutter constituent shapes 43 are arranged in a row between a one-end side gutter constituent shape 42 arranged on one end side in the left-right direction of the roof body 4 and an other-end side gutter constituent shape 44 arranged on the other end side. As shown in Figure 7, the intermediate gutter forming member 43 has an intermediate hollow section 431 arranged on one side, a solid intermediate solid gutter forming member 432 arranged on the other side in the left-right direction of the intermediate hollow section 431, a bead material mounting recess 433 formed on the side of the upper end portion of one side of the intermediate hollow section 431, an L-shaped middle gutter section 434 extending from approximately the center in the up-down direction to the intermediate gutter forming member 43 side on the surface of the intermediate hollow section 431 facing the intermediate gutter forming member 43, an L-shaped hook extension piece 435 extending downward from the lower end of one end of the middle gutter section 434, a one-side lower protruding piece 436 protruding to one side from the side of the lower end portion of the intermediate hollow section 431 facing the intermediate gutter forming member 43, an other-side upper outward extending piece 437 (connected portion), and a other-side lower outer piece 438.

[0060] As shown in FIG. 7, an opening 439 that opens downward is formed on the lower side of one end of the middle gutter section 434. The opening 439 is formed by an end side 431a extending in the vertical direction arranged on one side of the intermediate hollow section 431 in the middle gutter section 434 and an L-shaped hook extension piece 435. On the opening edge of the opening 439, an opposing protrusion 439a is formed that protrudes from the opening edge of the opening 439 to the inside of the opening 439 in an opposing relationship to each other. In this embodiment, the opposing protrusion 439a is composed of a lower protrusion piece 436 on one side and a hook piece 435b (described later) of the L-shaped hook extension piece 435, and protrudes and extends toward the inside of the opening 439 so as to approach each other.

[0061] In the one-end side gutter constituent shape member 42 and intermediate gutter constituent shape member 43 constructed as described above, when the adjacent one-end side gutter constituent shape member 42 and intermediate gutter constituent shape member 43 are connected, the hook engagement portion 428a of the one-end side gutter constituent shape member 42 is positioned inside the opening 439 of the adjacent intermediate gutter constituent shape member 43 and hooks onto and fits into the opposing protrusion 439a (the lower protrusion piece 436 on one side, the hook piece 435b of the L-shaped hook extension piece 435) so as to restrict movement in the vertical direction.

[0062] The bead material mounting recess 433 is disposed opposite the downward extending wall 427c of the adjacent one-end side gutter configuring shape member 42 on one side. The upper surface 433a of the bead material mounting recess 433 is formed at a position one step lower than the upper surface 4a of the roof body 4. The side extending wall 427b is disposed on the upper surface 433a of the bead material mounting recess 433. In other words, the side extending wall 427b is disposed overlapping a part of the upper surface 433a of the bead material mounting recess 433. The bead material mounting recess 433 extends in the direction in which the connecting portions of adjacent elongated shapes 41 extend, i.e., along the long dimension direction (lengthwise direction) of the elongated shapes 41.

[0063] A bead material 401 is attached to the bead material attachment recess 433. When attached to the bead material attachment recess 433, the bead material 401 presses against the downward extending wall 427c of the adjacent one-end side gutter component shape member 42 on one side. The bead material 401 is disposed at the connection portion between the one-end side gutter component shape member 42 and the intermediate gutter component shape member 43, and functions as a water stopper portion. As described above, the side extending wall 427b is disposed so as to overlap a portion of the upper surface 433a of the bead material mounting recess 433. Therefore, the bead material 401 is not directly exposed to the outside, so that the weather resistance of the bead material 401 can be improved and deterioration of the bead material 401 can be reduced.

[0064] The middle gutter section 434 has a bottom wall section 434a and an upright piece 434b. The middle gutter section 434 constitutes a middle gutter component 410 located in the middle section in the up-down direction inside the roof body 4. The middle gutter component 410 has a gutter function to allow water to flow, and also functions as a water stopper. The middle gutter component 410 receives water that has passed through the bead material 401 and was not able to be stopped by the bead material 401, and allows the received water to flow to both end sides in the front-to-rear direction.

[0065] The L-shaped hook extension piece 435 has a downward extension piece 435a and a hook piece 435b extending from a lower end of the downward extension piece 435a toward the widthwise center of the intermediate shape member 43. The hook piece 435b is engageable with a hook engagement portion 428a formed on the other end of the adjacent one-end side gutter constituent shape member 42. The hook piece 435b is rotatable about the hook engagement portion 428a in a state of being engaged with the hook engagement portion 428a.

[0066] When attaching an adjacent intermediate gutter configuring shape member 43 next to a one-end side gutter configuring shape member 42, the intermediate gutter configuring shape member 43 can be temporarily placed below the beam 3 by hooking the hook extension piece 435 of the intermediate gutter configuring shape member 43 onto the hook engagement portion 428a of the one-end side gutter configuring shape member 42 to which the extension plate portion 32 of the beam 3 is connected. Furthermore, with the hook extension piece 435 of the intermediate gutter configuring shape member 43 hooked onto the hook engagement portion 428a of the one-end side gutter configuring shape member 42, the intermediate gutter configuring shape member 43 can be rotated around the tip of the hook extension piece 435, so that the intermediate gutter configuring shape member 43 can be placed in the attachment position. When the intermediate gutter constituent shape member 43 is placed in the mounting position, the intermediate gutter constituent shape member 43 is mounted on the other side in the left-right direction of the one-end side gutter constituent shape member 42 with the hook extension piece 435 of the intermediate gutter constituent shape member 43 engaged with the hook engagement portion 428a of the one-end side gutter constituent shape member 42.

[0067] Regarding the points which will not be described, the other-side upper outward extending piece 437 and the other-side lower outer piece 438 of the intermediate gutter configuring shape member 43 are similar in structure to the other-side upper outward extending piece 427 and the other-side lower outer piece 428 of the one-end side gutter configuring shape member 42. Therefore, regarding the structures of the other-side upper outward extending piece 437 and the other-side lower outer piece 438 of the intermediate gutter configuring shape member 43, reference numerals corresponding to the structure of the one-end side gutter configuring shape member 42 in Fig. 7 are used, and description thereof will be omitted.

[0068] Moreover, since the configurations of the multiple intermediate gutter constituent shapes 43 arranged in succession are all the same, the description thereof will be omitted. When an adjacent intermediate gutter constituent shape 43 is attached next to an intermediate gutter constituent shape 43 connected to a beam 3, similarly to the case of attaching an intermediate gutter constituent shape 43 next to a one-end side gutter constituent shape 42, the intermediate gutter constituent shape 43 can be temporarily placed below the beam 3 by hooking the hook extension piece 435 of the intermediate gutter constituent shape 43 to the hook engagement portion 438a of the intermediate gutter constituent shape 43 connected to the extension plate portion 32 of the beam 3. Moreover, by rotating the intermediate gutter constituent shape 43 about the hook extension piece 435 with the hook engagement portion 438a of the intermediate gutter constituent shape 43 hooked, the intermediate gutter constituent shape 43 can be placed at the attachment position. When the adjacent intermediate gutter constituent shape member 43 is placed in the mounting position, the adjacent intermediate gutter constituent shape member 43 is mounted on the other left-right side of the intermediate gutter constituent shape member 43 with the hook extension piece 435 of the adjacent intermediate gutter constituent shape member 43 engaged with the hook engagement portion 438a of the intermediate gutter constituent shape member 43.

[0069] The other-end gutter component shape member 44 arranged at the other end in the left-right direction of the roof body 4 has a configuration on one side that is similar to the configuration of one end of the intermediate gutter component shape member 43, and the configuration other than that on one side is similar to the configuration of the one-end gutter component shape member 42 arranged at the other end by mirroring it left-right. Therefore, a description of the other-end gutter component shape member 44 arranged at the other end in the left-right direction of the roof body 4 will be omitted.

[0070] As shown in Figs. 5 to 7, the roof body 4 constructed as above is constructed by connecting a plurality of long shaped members 41 formed of extruded aluminum material, so that the plurality of long shaped members 41 can be used as the surface material of the roof body 4 and the strength of the roof body 4 can be ensured. In addition, the plurality of long shaped members 41 constituting the roof body 4 are configured to drain water by a plurality of concave roof body side gutter structures 40, and the intermediate gutter constituent member 43 is formed with an intermediate hollow portion 431, so that the roof body 4 itself can be used as a strength member. This eliminates the need to provide a separate member for increasing the strength of the roof body 4. Therefore, the number of parts constituting the roof body 4 can be reduced. In addition, the bead material mounting recess 433 is provided on one side of the intermediate hollow portion 431 of the intermediate gutter constituent member 43, so that the strength of the portion where the bead material 401 is attached can be ensured.

[0071] Furthermore, since the roof body end gutter structures 40a, 40c and the roof body intermediate gutter structure 40b are open at the upper side and form the multiple concave roof body side gutter structures 40 of the roof body 4, when viewed from below the roof body 4, only the flat (planar) lower surface 4b of the long material 41 is visible, and the gutter can be configured without making it clear that there is a gutter on the upper surface 4a of the roof body 4. This improves the design.

[0072] 1, the roof body upstream end cover member 8 is disposed at the upstream end of the roof body 4 in the front-to-rear direction, extending in the left-to-right direction of the roof body 4 (a direction perpendicular (intersecting) the longitudinal direction of the long member 41). The roof body upstream end cover member 8 is disposed at the upstream end of the roof body 4 in the front-to-rear direction, so as to cover the upstream side (end) of the long member 41.

[0073] As shown in Figures 8 to 10, the multiple roof body downstream end cover members 9 are arranged at the end of the roof body 4 on the downstream side in the tilt direction (front side in the front-rear direction). The multiple roof body downstream end cover members 9 are each arranged so as to cover the downstream end faces of the intermediate hollow sections 431 of the intermediate gutter configuring shapes 43 arranged at a distance in the left-right direction. This prevents the open end faces of the intermediate hollow sections 431 of the intermediate gutter configuring shapes 43 from being exposed to the outside at the front ends of the multiple long shapes 41 that make up the roof body 4.

[0074] In addition, as shown in Figure 9, each of the multiple roof body downstream end cover members 9 has a shielding inclined plate 91 that slopes downward from the upstream side to the downstream side, and a downward opening 92 formed between the lower end of the shielding inclined plate 91 and the lower end of the long member 41.

[0075] The downward opening 92 is formed facing downward at the lower end of the roof body downstream end cover member 9. Water flowing inside the long member 41 is discharged downward from the downward opening 92. A roof body downstream gutter structure 45 (described later) is arranged below the downward openings 92 of the multiple roof body downstream end cover members 9. Since the multiple roof body downstream end cover members 9 open downward, water flowing inside the intermediate hollow portion 431 of the intermediate gutter configuring member 43 flows into the roof body downstream gutter structure 45.

[0076] Furthermore, in the multiple roof body downstream end cover members 9, the upper end of the inclined shielding plate 91 is located inside the roof body 4, and the inclined shielding plate 91 is inclined downward as it goes from the upstream side to the downstream side, so that it is difficult to see from the ground 11 side below the other end side of the roof body 4. This improves the design of the roof body 4.

[0077] The roof body downstream gutter structure 45 is disposed below the downstream (front in the fore-aft direction) ends of the multiple long members 41 constituting the roof body 4, and is fixed to the lower parts of the downstream ends of the multiple long members 41. The roof body downstream gutter structure 45 is formed in a gutter shape that is open at the top, and extends across the entire area of ​​the roof body 4 in the left-right direction.

[0078] The roof body downstream gutter structure 45 has a downstream gutter main body 451 that is open at the top, an upstream inward extending piece 452 that extends approximately horizontally from the upstream upper end of the downstream gutter main body 451 to the inside of the downstream gutter main body 451, an upstream lower bent piece 453 formed upstream of the upstream lower end of the downstream gutter main body 451, a downstream inward extending piece 454 that extends approximately horizontally from the downstream upper end of the downstream gutter main body 451 to the inside of the downstream gutter main body 451, and a downstream upward protruding piece 455 that protrudes upward from the downstream upper end of the downstream gutter main body.

[0079] The undersides of the downstream ends of the multiple long members 41 are disposed on the upper surface of the upstream inward extending piece 452 of the roof body downstream gutter structure 45, and the upstream inward extending piece 452 of the roof body downstream gutter structure 45 is fixed to the undersides of the multiple long members 41 at their downstream ends by screw members 106, as shown in Figures 8 and 10. The upstream inward extending piece 452 of the roof body downstream gutter structure 45 and the downstream ends of the multiple long members 41 are fastened together and fixed by screw members 106 which are moved from above the roof body gutter structure 40, as shown in Figure 8.

[0080] Here, as shown in Figure 10, even if screw holes 402 through which screw members 106 pass are formed in the long members 41 of the roof body 4, the roof body downstream gutter structure 45 is disposed below the screw holes 402. Therefore, water from the screw holes 402 drops into the roof body downstream gutter structure 45 and is received by the roof body downstream gutter structure 45. This makes it possible to attach the roof body downstream gutter structure 45 to the roof body 4 while preventing water from dropping below the roof body 4.

[0081] Water that has flowed through the multiple concave roof body gutter structures 40 formed on the upper surface 4a of the roof body 4 and water discharged from inside the multiple long members 41 that make up the roof body 4 flow into the roof body downstream gutter structure 45. Discharge openings 45a are formed on the underside of both left and right ends of the roof body downstream gutter structure 45, as shown in Figure 8.

[0082] 8, the pair of downward-side inclined gutter structures 46 are arranged below the roof body 4, at both ends of the roof body 4 in the direction in which the elongated members 41 are arranged. The downward-side inclined gutter structures 46 have an introduction portion 461, an inclined gutter portion 462, and a connection guide portion 463.

[0083] The introduction section 461 is formed in a cylindrical shape with its front side open upward in the front-to-rear direction of the roof body 4 and connected to the discharge openings 45a on the underside of the left-to-right ends of the roof body downstream gutter structure 45. The introduction section 461 is formed with its rear side open to the rear in the front-to-rear direction of the roof body 4 and connected to the inclined gutter section 462.

[0084] The inclined gutter section 462 is formed in a generally C-shaped cross section with an open upper portion. One end of the inclined gutter section 462 is connected to the introduction section 461, and extends from the front to the rear in the front-to-rear direction of the roof body 4 below the one-end gutter component shape 42 or the other-end gutter component shape 44 along the longitudinal direction of the one-end gutter component shape 42 or the other-end gutter component shape 44. The inclined gutter section 462 inclines downward as it moves from the front to the rear of the roof body 4. A connection guide section 463 is connected to the downstream end of the inclined gutter section 462.

[0085] The connection guiding section 463 has a rear opening 463a formed on the rear side of the roof body 4, and a side opening 463b opening to the outside in the left-right direction of the roof body 4. The rear opening 463a of the connection guiding section 463 is connected to the downstream end of the inclined gutter section 462. The side opening 463b of the connection guiding section 463 is connected to the side of the support column 2, and is connected to a support column side gutter component 20 (see FIG. 5) provided inside the support column 2.

[0086] Next, the flow of rainwater in the carport 1 of this embodiment will be described. In the carport 1 shown in Figure 1, rainwater falling on the upper surface 4a of the roof body 4 flows from the upstream side to the downstream side in the inclination direction of the roof body 4 (from the rear side to the front side in the fore-and-aft direction) along multiple concave roof body side gutter structures 40 extending in the longitudinal direction of the long members 41 formed on the upper surface 4a.

[0087] Water flowing downstream on the front side of the upper surface 4a of the roof body 4 in the front-to-rear direction passes through multiple concave roof body side gutter structures 40 formed on the upper surface 4a of the roof body 4, flows downstream in the inclination direction of the upper surface 4a of the roof body 4, passes under the beams 3, and reaches the roof body downstream side gutter structure 45. This allows water flowing through the roof body 4 and dirt washed away by the water (e.g., fallen leaves, etc.) to pass through the multiple concave roof body side gutter structures 40 below the beams 3, and allows the water and dirt washed away by the water to flow from the upstream side to the downstream side in the inclination direction of the roof body 4. This improves drainage performance.

[0088] Inside the long member 41, water introduced into the middle gutter component 410 and the lower gutter component 420 flows toward the downstream end in the fore-aft direction of the roof body 4. The water that has flowed toward the downstream end in the fore-aft direction is discharged from the lower openings 92 at the bottom of the multiple roof body downstream end cover members 9 at the downstream end to the roof body downstream gutter structure 45.

[0089] Water that has flowed over the upper surface 4a of the roof body 4 and water discharged from the internal gutter components (middle gutter component 410 and lower gutter component 420) of the multiple long members 41 that make up the roof body 4 flow into the roof body downstream gutter structure 45. A discharge opening 45a (see Figure 8) is formed in the underside of one end of the roof body downstream gutter structure 45 in the left-right direction.

[0090] Water that has flowed into the roof body downstream gutter structure 45 is guided through discharge openings 45a formed on both left and right end sides of the roof body 4, and through a downward inclined gutter structure 46 arranged below the roof body 4 at the end side in the direction in which the long members 41 of the roof body 4 are lined up, to a pillar side gutter component 20 (see FIG. 5) provided inside the pillar 2. The water that has flowed into the pillar side gutter component 20 falls through the pillar side gutter component 20 and is discharged below the pillar 2 to the outside of the pillar 2.

[0091] In the roof structure configured as above, a plurality of concave roof body side gutter structures 40 are formed on the upper surface 4a of the roof body 4. Therefore, water flowing on the upper surface 4a of the roof body 4 passes below the beams 3 and flows toward the downstream side in the inclination direction of the roof body 4 (the front side in the front-to-rear direction). This improves drainage performance.

[0092] In addition, since the upper surface 4a of the roof body 4 is provided with multiple concave roof body side gutter structures 40, the beam 3 can be directly connected to the roof body 4 without the need for a hanger or the like between the beam 3 and the roof body 4. Therefore, the beam 3 and the roof body 4 can be arranged in close contact with each other. As a result, the beam 3 can be installed at a low position above the roof body 4, so that the beam 3 does not protrude upward significantly when viewed from below, making the thickness of the roof structure including the roof body 4 appear thin, and the roof structure can be formed compactly. Therefore, a smart carport 1 can be realized and the design can be improved.

[0093] In addition, the roof body 4 is formed by arranging multiple long members 41 in a row, and the underside 4b of the roof body 4 is formed in a flat shape, which improves the design when the roof body 4 is viewed from below.

[0094] The carport 1 of this embodiment described above provides the following advantages. The carport 1 of this embodiment includes a support 2, a beam 3 connected to the support 2, and a roof body 4 connected directly or indirectly to the beam 3, the roof body 4 having a plurality of long members 41 arranged in a row in a predetermined direction. The roof body 4 has a flat lower surface 4b and a plurality of concave roof body side gutter structures 40 on at least a part of the upper surface 4a. Therefore, since the beam 3 and the roof body 4 are provided with a plurality of concave roof body side gutter structures 40, water flowing through the roof body 4 and dirt washed away by the water (e.g., fallen leaves, etc.) can pass through the plurality of concave roof body side gutter structures 40 and flow toward the downstream side of the inclination direction of the roof body 4. This improves drainage performance. In addition, since the lower surface 4b of the roof body 4 is formed in a flat shape, the design can be improved.

[0095] Furthermore, in this embodiment, the roof body 4 is configured to include a plurality of long members 41 each having a concave roof body gutter structure 40. This makes it possible to form a plurality of roof body gutter structures 40 on the upper surface 4a of the roof body 4 simply by connecting a plurality of long members 41 together. This makes it possible to improve drainage performance with a simple configuration.

[0096] Furthermore, in this embodiment, in the portion where the multiple intermediate gutter constituent shapes 43 are connected, the roof body 4 is configured to include multiple intermediate gutter constituent shapes 43 having a concave roof body side gutter structure 40 and a hollow structure in which a hollow portion is formed. As a result, in the intermediate gutter constituent shapes 43 of the roof body 4, the roof body side gutter structure 40 ensures water circulation, while the hollow structure ensures the strength of the roof body 4. Furthermore, since the intermediate gutter constituent shapes 43 have a hollow structure, they have strength as shapes. Therefore, the workability when connecting the multiple intermediate gutter constituent shapes 43 is good, and the workability when constructing the roof body 4 can be improved.

[0097] In this embodiment, the upper surface 4a of the roof body 4 is provided with a portion that is directly connected to the beam 3 (the one-side upper inward extending piece 423 and the other-side upper outward extending piece 427 of the one-end side gutter component shape member 42, the other-side upper outward extending piece 437 of the intermediate gutter component shape member 43, and the other-side upper inward extending piece 443 of the other-end side gutter component shape member 44), and the roof body 4 is disposed below the beam 3 and directly suspended from the beam 3. Therefore, the beam 3 and the roof body 4 can be disposed in close contact with each other. As a result, the beam 3 can be installed at a low position above the roof body 4, so that the beam 3 does not protrude upward significantly when viewed from below, and the thickness of the roof structure including the roof body 4 can be made to look thin, and the roof structure can be formed compactly. Therefore, a smart carport 1 can be realized, and the design can be improved.

[0098] Furthermore, in this embodiment, the roof body 4 is inclined downward from one side to the other side in the longitudinal direction of the long member 41. Therefore, the roof body 4 is inclined in the direction in which the multiple concave roof body side gutter structures 40 extend. This makes it easier for water flowing through the roof body 4 and dirt washed away by the water (e.g., fallen leaves, etc.) to pass through the multiple concave roof body side gutter structures 40 and be guided to the downstream side of the roof body 4. This further improves drainage performance.

[0099] In this embodiment, the long member 41 is made of an aluminum material and has a hollow structure having a hollow portion at least in a part thereof. This allows the strength of the roof body 4 to be ensured by the hollow structure having a hollow portion.

[0100] A preferred embodiment of the carport (roof structure) of the present invention has been described above, but the present invention is not limited to the above-mentioned embodiment and can be modified as appropriate. For example, in the above embodiment, the roof body 4 is directly connected (fixed) to the beam 3 below the beam 3, but this is not limited to this, and the roof body 4 may be indirectly connected (fixed) to the beam via other members.

[0101] Further, in the above embodiment, the roof body 4 is configured to be suspended from the beams 3, but this is not limited thereto, and the roof body 4 may be configured to be disposed above the beams 3.

[0102] In addition, in the above embodiment, the roof body 4 is constructed by connecting a plurality of intermediate gutter constituent shapes 43 each having a roof body side gutter structure 40 and a hollow structure, but this is not limited to the above. The roof body side gutter structure 40 and the hollow structure may be constructed separately, and the roof body 4 may be constructed by connecting a plurality of roof body side gutter structures 40 and a plurality of hollow structures.

[0103] In addition, in the above embodiment, all of the long members 41 of the roof body 4 have the concave roof body side gutter structure 40, but this is not limited to the above. The roof body 4 may be configured to include a plurality of long members 41 having at least a concave roof body side gutter structure 40. In addition, in the above embodiment, all of the intermediate gutter constituent members 43 of the roof body 4 have the concave roof body side gutter structure 40 and a hollow structure, but this is not limited to this. The roof body 4 may be constituted by including a plurality of long members, at least some of which have the concave roof body side gutter structure 40 and a hollow structure.

[0104] In addition, in the above embodiment, the roof body 4 is formed by continuously connecting a plurality of long shaped members 41 each having a roof body side gutter structure 40, but the present invention is not limited to this. For example, a long shaped member 41 not having a roof body side gutter structure 40 may be connected next to a long shaped member 41 having a roof body side gutter structure 40. For example, the roof body 4 may be formed by connecting a mixture of long shaped members 41 having a roof body side gutter structure 40 and long shaped members 41 not having the roof body side gutter structure 40.

[0105] Furthermore, in the above embodiment, the roof body 4 is configured to be inclined in the front-rear direction, but this is not limiting, and the roof body 4 may be configured to be inclined in the left-right direction.

[0106] In addition, in the above embodiment, the carport has been described as a so-called double-support structure carport, in which the roof body 4 is supported by a pair of pillars 2 on each of the left and right sides, but this is not limited to this, and the carport may also be a so-called cantilever structure carport, in which one end of the roof body 4 in the left and right direction is supported by a pillar.
