[0008] Hereinafter, embodiments of the roof structure of this disclosure will be described with reference to the drawings. In this embodiment, an example in which the roof structure is applied to a carport 1 will be described. In this embodiment, the carport 1 has parking space for multiple cars below the roof body 4. In this embodiment, an example in which the roof structure is applied to a carport 1 will be described, but it is not limited to this. Furthermore, the roof structure may be applied to structures other than carports, such as bicycle parking areas, shelters, rest areas, terraces, bus stops, and so on.

[0009] In the descriptions of the first to fifth embodiments, the direction in which the first beam 3 of the carport 1 extends is also referred to as the front-to-back direction Y. In the front-to-back direction Y in which the first beam 3 extends, the side on which the first support column 2 extends is also referred to as the rear side Y1, and the side opposite to the first support column 2 is also referred to as the front side Y2. In the first to fifth embodiments, the roof body 4 is sloped downwards in the front-to-back direction Y, from the front side Y2 (the tip side of the first beam 3) to the rear side Y1 (the base end side of the first beam 3), with the front side Y2 also referred to as the upstream side and the rear side Y1 also referred to as the downstream side. The direction in which the multiple long profiles 41 (long members) constituting the roof body 4 extend, which intersects the direction in which the first beam 3 extends, is also referred to as the left-to-right direction X.

[0010] First, the overall structure of the carport 1 of the first embodiment will be described. As shown in Figures 1 to 3, the carport 1 of this embodiment is a carport in which the roof body 4 is supported at the rear side Y1 in the front-rear direction Y by two first support columns 2, and connected to a first beam 3 connected to the upper end of the first support columns 2, and supported on both sides in the left-right direction X by second support columns 5. The roof body 4 of the carport 1 of this embodiment is formed to be large enough to cover the area above when multiple cars are parked. Furthermore, the carport 1 of this embodiment is configured as a suspension structure in which the roof body 4 is suspended and connected to the lower part (below) of the first beam 3 connected to the first support columns 2.

[0011] As shown in Figures 1 and 2, the carport 1 of this embodiment comprises two first support columns 2 erected on the ground, two first beams 3, a roof body 4 positioned below the two first beams 3, a pair of second support columns 5 positioned on both sides of the roof body 4 in the left-right direction X at a position closer to the front Y2 of the roof body 4 in the front-rear direction Y, and a pair of second beams 6 positioned on the outside of each of the two first beams 3 in the left-right direction X, connecting the second support columns 5 and the first beams 3. The first support columns 2, first beams 3, second support columns 5 and second beams 6 are formed from extruded aluminum profiles and have a hollow structure with a hollow cross-section.

[0012] As shown in Figures 1 to 3, the two first support columns 2 are positioned at the rear end Y1 in the front-to-back direction Y of the carport 1, separated in the left-to-right direction X. The first support columns 2 extend in the vertical direction.

[0013] As shown in Figure 1, the two first beams 3 are each connected to the upper end of the first support column 2 and extend from the upper end of the first support column 2 in a direction intersecting the first support column 2. Both first beams 3 extend in the front-rear direction Y of the roof body 4. The rear end Y1 of each of the two first beams 3 in the front-rear direction Y is connected to the upper end of the first support column 2 via an L-shaped connecting member 21, as shown in Figure 4. The roof body 4 is connected to the lower parts of the two first beams 3. With the roof body 4 connected to the lower parts of the two first beams 3, the two first beams 3 are positioned above the roof body 4 and extend in the front-rear direction Y along the upper surface 4a of the roof body 4.

[0014] As shown in Figures 1, 3, and 4, the two first beams 3 each have a beam body portion 31 having a hollow section with a rectangular tubular cross-section and an extended plate portion 32.

[0015] The extension plate portion 32 extends from the lower end of the beam body portion 31 toward the inside in the left-right direction X of the roof body 4 (towards the side of the first beam 3 other than the first beam 3 in question) and is formed as a plate that extends in the front-rear direction Y. As shown in Figures 3 and 4, the extension plate portion 32 is fixed to the roof body 4 by a plurality of screws 101 arranged in the front-rear direction Y.

[0016] As shown in Figure 1, the roof structure 4 is a suspended structure in which the roof structure 4 is suspended and positioned below the two first beams 3, and is connected to the lower parts of the two first beams 3. The roof structure 4 is constructed by connecting a plurality of long profiles (long members) 41 in a row in the front-rear direction Y along which the first beams 3 extend, and fitting together to connect them. The roof structure 4 is formed with a downward slope from the side away from the first support column 2 (front side Y2 in the front-rear direction Y) towards the side of the first support column 2 (rear side Y1 in the front-rear direction Y).

[0017] As shown in Figure 4, the upper surface 4a of the roof body 4 is formed with a downward slope in the front-rear direction Y of the roof body 4, for example, at an inclination angle α, and the slope descends from the front side Y2 (right side in Figure 4) to the rear side Y1 (left side in Figure 4) in the front-rear direction Y of the roof body 4. Therefore, in terms of the flow of water over the upper surface 4a of the roof body 4, the front side Y2 is the upstream side and the rear side Y1 is the downstream side. In this embodiment, for example, the inclination angle α in the front-rear direction Y of the roof body 4 is set to about 1° to 2°. Also, the roof body 4 is not inclined in the left-right direction X and extends horizontally.

[0018] As shown in Figures 1 to 3, the multiple long profiles 41 all extend in the left-right direction X of the carport 1 (a direction perpendicular to the direction in which the first beam 3 extends). The multiple long profiles 41 are all formed from extruded aluminum profiles. Of the multiple long profiles 41, the intermediate profile 43 and the upstream end profile 44 have a hollow structure with a hollow section formed in a hollow cross-section. The roof body 4 has a flat (planar) upper surface 4a and lower surface 4b.

[0019] As shown in Figure 4, the multiple elongated profiles 41 that make up the roof body 4 are arranged in a line in the front-rear direction Y, and include a downstream gutter profile 42 located at the rearmost Y1, an upstream end profile 44 located at the frontmost Y2, and a plurality of intermediate profiles 43 located between the downstream gutter profile 42 and the upstream end profile 44.

[0020] Multiple long profiles 41 are attached to adjacent long profiles 41 by interlocking, and each of the multiple long profiles 41 is directly fixed and connected to the extended plate portion 32 of the first beam 3 by screws 101. Details of the multiple long profiles 41 that make up the roof body 4 (downstream gutter profile 42, intermediate profile 43, upstream end profile 44) will be described later.

[0021] As shown in Figures 1 to 3, the pair of second support columns 5 are positioned on the sides of both ends of the roof body 4 in the left-right direction X (the direction intersecting the direction in which the first beam 3 extends), near the front Y2 of the roof body 4 in the front-rear direction Y. Each of the pair of second support columns 5 extends in the vertical direction. In this embodiment, each of the pair of second support columns 5 is positioned in the front-rear direction Y, closer to the front Y2 than the center of the front-rear direction Y.

[0022] The second support column 5 is indirectly connected to the side surface of the first beam 3 via the second beam 6. In this embodiment, the second support column 5 is indirectly connected to the side surface of the first beam 3 via the second beam 6, but this is not the only way. The second support column 5 may also be directly connected to the side surface of the first beam 3. Furthermore, the position of the second support column 5 in the front-rear direction Y (the direction in which the first beam 3 extends) can be set to any position depending on the surrounding circumstances where there are positions where the second support column 5 cannot be installed. This makes it possible to install the second support column 5 and the second beam 6 at any position in the front-rear direction Y in which the first beam 3 extends.

[0023] The two second beams 6 are each positioned above the roof body 4, along the upper surface 4a of the roof body 4, on the outer side in the left-right direction X of each of the two first beams 3, and are formed at approximately the same height as the two first beams 3, extending in the left-right direction X that intersects the front-rear direction Y from which the first beams 3 extend. The two second beams 6 are each positioned between the side of the first beam 3 and the upper end of the second support column 5, and are positioned on the outer side in the left-right direction X of each of the two first beams 3, extending between the side of the first beam 3 and the upper end of the second support column 5. The two second beams 6 each connect the side of the first beam 3 and the second support column 5.

[0024] As shown in Figure 5, the outer end (first portion) of the second beam 6 in the left-right direction X is connected to the upper end of the second support column 5 via an L-shaped connecting member 51. The inner end (second portion) of the second beam 6 in the left-right direction X is connected to and fixed to the side surface of the first beam 3 by a pair of L-shaped brackets 61 and 62 (mounting brackets), as shown in Figures 3, 5, and 6.

[0025] As shown in Figures 3, 5, and 6, at the connection point between the inner end of the second beam 6 in the left-right direction X and the side surface of the first beam 3, the L-shaped bracket 61 is positioned on the rear side Y1 of the second beam 6 in the front-rear direction Y, and the L-shaped bracket 62 is positioned on the front side Y2 of the second beam 6 in the front-rear direction Y.

[0026] As shown in Figures 3 and 6, the L-shaped bracket 61 is formed in an L-shape and is positioned at the rear Y1 side in the front-to-back direction Y of the second beam 6 at the inner end of the second beam 6 in the left-to-right direction X, straddling the outer side of the first beam 3 in the left-to-right direction X and the rear Y1 side of the second beam 6 in the front-to-back direction Y. The L-shaped bracket 61 has a plate-shaped first fixing plate 611 that follows the outer side of the first beam 3 in the left-to-right direction X, and a plate-shaped second fixing plate 612 that is formed by bending outward in the left-to-right direction X from the front Y2 end of the first fixing plate 611 and follows the rear Y1 side of the second beam 6 in the front-to-back direction Y. The first fixing plate 611 is screw-fixed to the outer side of the first beam 3 in the left-to-right direction X. The second fixing plate 612 is screw-fixed to the rear Y1 side in the front-to-back direction Y of the second beam 6 at the inner end of the second beam 6 in the left-to-right direction X.

[0027] As shown in Figures 3 and 6, the L-shaped bracket 62 is formed in an L-shape and is positioned at the front Y2 side in the front-to-back direction Y of the second beam 6 at the inner end of the second beam 6 in the left-to-right direction X, straddling the outer side of the first beam 3 in the left-to-right direction X and the front Y2 side of the second beam 6 in the front-to-back direction Y. The L-shaped bracket 62 has a plate-shaped first fixing plate 621 that follows the outer side of the first beam 3 in the left-to-right direction X, and a plate-shaped second fixing plate 622 that is formed by bending outward in the left-to-right direction X from the rear Y1 end of the first fixing plate 621 and follows the front Y2 side of the second beam 6 in the front-to-back direction Y. The first fixing plate 621 is screw-fixed to the outer side of the first beam 3 in the left-to-right direction X. The second fixing plate 622 is screw-fixed to the front Y2 side of the second beam 6 at the inner end of the second beam 6 in the left-to-right direction X.

[0028] In this embodiment, the side surface of the first beam 3 and the second beam 6 are connected by L-shaped brackets 61 and 62, but the invention is not limited to this configuration. The side surface of the first beam 3 and the second beam 6 may be directly connected.

[0029] Further explanation will be given regarding the structure of the roof body 4. Details of the multiple long profiles 41 (downstream gutter profile 42, intermediate profile 43, and upstream end profile 44) that make up the roof body 4 will be explained.

[0030] As shown in Figure 4, the downstream gutter structural member 42 is arranged in parallel at the rear end Y1 of the multiple long structural members 41 of the roof body 4, where the multiple long structural members 41 are lined up in the front-to-back direction Y. In this embodiment, the downstream gutter structural member 42 is formed from a solid member without a hollow section, and is formed in a U-shape in cross-section with the upper side opening upwards.

[0031] The downstream gutter component 42 forms a roof-side gutter component 40 at the rear Y1 end of the roof body 4 in the front-rear direction Y, receiving and circulating water that flows from the front Y2 to the rear Y1 on the upper surface 4a of the roof body 4 and reaches the end of the rear Y1. The roof-side gutter component 40 is formed extending in the longitudinal direction of the long component 41.

[0032] Since the upper side of the roof-side gutter component 40 is open, when the roof-side gutter component 40 is viewed from below the roof 4, only the flat (planar) lower surface of the long profile 41 is visible, and the gutter can be constructed without making it apparent that a gutter exists on the upper surface 4a of the roof 4, thereby improving the aesthetic appearance.

[0033] As shown in Figure 7, the downstream gutter component 42 has a solid end-side solid gutter component 421 formed on the rear side Y1 of the roof body 4 in the front-rear direction Y and open upward, a front upper outward extending piece 427 formed on the front side Y2 of the roof body 4 in the front-rear direction Y, and a front lower outward piece 428 formed on the front side Y2 of the roof body 4 in the front-rear direction Y.

[0034] The end-side solid gutter component 421 includes a roughly U-shaped concave gutter component body 422 that is open at the top, a rear upper inward extension piece 423 positioned on the rear side Y1 in the front-rear direction Y of the roof body 4, a front upper inward extension piece 424, a water drainage fin 425, and a rear upper wall 426.

[0035] The gutter component body 422 receives water that flows from the upper surface 4a of the roof body 4 towards the first support column 2, by introducing it from the open upper portion. An outlet opening 422a (drain outlet) is formed on the rear side Y1 of the gutter component body 422 in the front-rear direction Y. A guide member 22 is connected to the outlet opening 422a. The guide member 22 guides the water that flows into the roof body side gutter component 40 and accumulates there to the support column side gutter component 20.

[0036] The rear upper inward extension piece 423 protrudes from the inner surface of the front Y2 above the end solid gutter component 421 at the rear Y1 of the end solid gutter component 421 to the front Y2. The extension plate portion 32 of the first beam 3 is positioned on the upper surface of the rear upper inward extension piece 423. The extension plate portion 32 of the first beam 3 and the rear upper inward extension piece 423 are fastened together with a screw 101.

[0037] The front upper inward extension piece 424 protrudes from the upper end of the end-side solid gutter component 421 to the rear side Y1 at the front side Y2 in the width direction of the end-side solid gutter component 421. A hooking projection piece 424a that protrudes downward is formed at the rear side Y1 end of the front upper inward extension piece 424.

[0038] When attaching the downstream gutter component 42 to the first beam 3, the downstream gutter component 42 can be temporarily placed on the underside of the extension plate portion 32 of the first beam 3 by hooking the hooking projection 424a of the downstream gutter component 42 onto the rising plate 110a of the hook portion 110 fixed to the underside of the extension plate portion 32 of the first beam 3. Furthermore, with the hooking projection 424a of the downstream gutter component 42 hooked onto the rising plate 110a of the hook portion 110 fixed to the underside of the extension plate portion 32 of the first beam 3, the downstream gutter component 42 can be positioned in the mounting location by rotating the downstream gutter component 42 around the hooking projection 424a.

[0039] The water drainage fins 425 protrude downward from the lower end of the gutter component body 422 at the rear Y1 of the roof body 4 on the gutter component body 422. The water drainage fins 425 direct water transmitted from the front Y2 to the rear Y1 in the front-rear direction Y by the side frame material 45 (see Figure 1) (described later) downward to the roof body 4 so that it does not flow around to the lower surface 4b of the roof body 4.

[0040] The rear upper wall 426 is formed by standing upright from the upper surface 4a of the roof body 4 at the end of the rear side Y1 of the roof body 4. The rear upper wall 426 reduces the splashing of water at the end of the rear side Y1 of the roof body 4.

[0041] The front upper outer extension piece 427 extends from the upper end of the front side Y2 in the front - rear direction Y of the roof body 4 in the gutter component body 422 toward the front side Y2 in the front - rear direction Y. The front upper outer extension piece 427 is disposed at the upper end of the end of the front side Y2 in the front - rear direction Y of the downstream gutter forming member 42 and is fixed to the extension plate portion 32 of the first beam 3 by the screw 101.

[0042] At the end of the front side Y2 in the front - rear direction Y of the roof body 4 on the front upper outer extension piece 427, a side extension wall 427b extending sideward and a downward extension wall 427c are formed.

[0043] On the surface of the downward extension wall 427c at the front side Y2 in the front - rear direction Y of the roof body 4, a bead material 401 (water - stop material) attached to the end of the rear side Y1 of the adjacent intermediate member 43 is pressed. The bead material 401 functions as a water - stop portion disposed at the connection portion between the downstream gutter forming member 42 and the intermediate member 43. The bead material 401 is formed to extend along the direction in which the connection portion between the downstream gutter forming member 42 and the adjacent intermediate member 43 (long - shaped member 41) extends, that is, along the long - shaped direction (longitudinal direction) of the long - shaped member 41. The portion water - stopped by the bead material 401 constitutes the primary water - stop structure in the roof body 4.

[0044] As shown in FIG. 7, the front lower outer piece 428 extends from the lower end of the front side Y2 in the front - rear direction Y of the roof body 4 in the gutter component body 422 toward the front side Y2. At the end of the front side Y2 on the front lower outer piece 428, a hook engaging portion 428a protruding upward is formed.

[0045] The engaging portion 428a is formed at the lower end of the downstream gutter forming member 42 at the front end Y2 in the front-rear direction Y of the downstream gutter forming member 42 attached to the first beam 3. The engaging portion 428a rises upward from the front lower outer piece 428 disposed at the lower end of the downstream gutter forming member 42 at the front end Y2 in the front-rear direction Y of the downstream gutter forming member 42 attached to the first beam 3, and is formed in a T-shape extending in the width direction orthogonal to the longitudinal direction of the long member 41 at the raised upper end portion.

[0046] The engaging portion 428a of the downstream gutter forming member 42 is engageable with a rear lower protruding piece 436 (described later) protruding to the rear side Y1 from the side surface of the lower end of the rear side Y1 of the adjacent intermediate member 43 and a engaging piece 435b (described later) of the engaging extension piece 435 formed at the end of the rear side Y1 of the adjacent intermediate member 43.

[0047] On the upper surface of the front lower outer piece 428, water that has overflowed from the middle gutter component 410 (middle water receiving portion, water stopping portion) in the adjacent intermediate member 43 flows between the vertical wall portion 422b on the front side Y2 of the gutter component main body 422 and the downward extension piece 435a of the engaging extension piece 435 formed at the end of the rear side Y1 of the adjacent intermediate member 43. The middle gutter component 410 stops water that could not be stopped by the bead material 401, which is a primary water stopping structure, in the middle in the vertical direction at the connecting portion between the adjacent long members 41, and is a secondary water stopping structure in the water stopping structure of the roof body 4. The middle gutter component 410 is disposed in the middle in the vertical direction at the connecting portion between the adjacent long members 41. Details of the middle gutter component 410 will be described later.

[0048] The upper surface of the front lower outer piece 428 constitutes a lower gutter component 420 (lower water receiving portion, water stopping portion) located in the lower stage in the vertical direction inside the roof body Ⅳ together with the vertical wall portion 422b on the front side Y2 of the gutter component main body 422 and the downward extension piece 435a (described later) of the engaging extension piece 435 formed at the end of the rear side Y1 of the adjacent intermediate member 43.

[0049] The lower gutter component 420 is positioned in the lower position in the vertical direction at the connection point between adjacent elongated profiles 41. The lower gutter component 420 has the function of a gutter for draining water and also functions as a water-stopping section. The lower gutter component 420 receives water that passes through the bead material 401 and is received by the middle gutter component 410 (described later), and receives water that overflows from the middle gutter component 410. The lower gutter component 420 directs the water that overflows from the middle gutter component 410 to both ends in the left-right direction X of the elongated profiles 41. The lower gutter component 420 has the function of receiving and stopping water that overflows from the middle gutter component 410 when it cannot be stopped by the bead material 401 which constitutes the first water-stopping structure and flows to the middle gutter component 410 which constitutes the second water-stopping structure, thus constituting the third water-stopping structure in the water-stopping structure of the roof body 4.

[0050] As shown in Figure 4, the multiple intermediate profiles 43 are arranged side by side between the downstream gutter profile 42 and the upstream end profile 44 in the front-rear direction Y of the roof body 4. The multiple intermediate profiles 43 are formed from elongated profiles having a hollow structure with a hollow section.

[0051] As shown in Figure 8, the intermediate profile 43 includes a first intermediate hollow portion 431 positioned on the rear side Y1 in the front-rear direction Y, a second intermediate hollow portion 432 positioned on the front side Y2 in the front-rear direction Y of the first intermediate hollow portion 431, a bead material mounting recess 433 formed on the side surface of the upper end of the rear side Y1 of the first intermediate hollow portion 431, a middle trough portion 434 connected below the bead material mounting recess 433 and having an inclined portion 4342 that slopes downward from the front side Y2 toward the rear side Y1 in the front-rear direction Y, an L-shaped hook extension piece 435 extending downward from the middle of the inclined direction of the inclined portion 4342 of the middle trough portion 434, a rear lower projection piece 436 projecting toward the rear side Y1 from the side surface of the lower end of the first intermediate hollow portion 431 on the intermediate profile 43 side, a front upper outward extension piece 437, and a front lower outward piece 438.

[0052] The bead material mounting recess 433 is positioned opposite the downwardly extending wall 427c of the downstream gutter component 42 adjacent to the rear side Y1. The bead material mounting recess 433 extends in the direction in which the connecting portion of the adjacent long component 41 extends, that is, along the longitudinal direction (longitudinal direction) of the long component 41.

[0053] A bead material 401 is attached to the bead material mounting recess 433. While attached to the bead material mounting recess 433, the bead material 401 presses against the downwardly extending wall 427c of the downstream gutter component 42 adjacent to the rear side Y1. The bead material 401 is positioned at the upper end of the connection between the downstream gutter component 42 and the intermediate component 43 and functions as a watertight seal. The configuration in which watertight seals are provided by the bead material 401 is the primary watertight seal in the watertight seal structure of the roof body 4. The bead material 401 (watertight seal) is positioned between adjacent long components 41 at the upper end of the connection between adjacent long components 41.

[0054] The upper surface 433a of the bead material mounting recess 433 is formed at a position lower than the upper surface 4a of the roof body 4. A lateral extension wall 427b is positioned on the upper surface 433a of the bead material mounting recess 433. The lateral extension wall 427b is positioned overlapping the upper surface 433a of the bead material mounting recess 433. As a result, the bead material 401 is not directly exposed to the outside, which improves the weather resistance of the bead material 401 and reduces deterioration of the bead material 401.

[0055] The intermediate gutter section 434 constitutes an intermediate gutter component 410 located in the middle of the vertical direction within the roof body 4. The intermediate gutter component 410 is formed in the middle of the vertical direction of the connecting portion between adjacent long profiles 41. The intermediate gutter component 410 is formed above the fitting space opening 439, straddling the fitting space opening 439, and extends to the outside in the width direction of the fitting space opening 439.

[0056] As shown in Figure 8, the fitting portion arrangement space opening 439 is formed below the middle gutter component 410 (middle water receiving portion). The fitting portion arrangement space opening 439 is formed to open downwards and is formed by a space enclosed by an upright plate 431a positioned on the rear side Y1 of the first intermediate hollow portion 431 and rising upward from the bottom surface, an L-shaped hook extension piece 435, and the inclined portion 4342 of the middle gutter portion 434. The fitting portion of the connecting portion between adjacent long profiles 41 is arranged in the fitting portion arrangement space opening 439. The joint portion 46 at the bottom of the connecting portion between adjacent long profiles 41 is arranged in the fitting portion arrangement space opening 439.

[0057] Opposing protrusions 439a and 439b are formed at the opening edge of the fitting space opening 439, projecting inward from the opening edge of the fitting space opening 439 and facing each other. In this embodiment, the opposing protrusion 439a is made up of a rear lower protruding piece 436. The opposing protrusion 439b is made up of a hooking piece 435b (described later) of an L-shaped hooking extension piece 435. The opposing protrusions 439a and 439b project inward from the fitting space opening 439 so that they move closer to each other.

[0058] As shown in Figure 8, the intermediate gutter section 434 that constitutes the intermediate gutter structure 410 has an upstream end water receiving section 4341, an inclined section 4342, and a downstream end projection 4343 (projection) formed at the downstream end of the inclined section 4342 and projecting upward.

[0059] The upstream end water receiving portion 4341 is positioned at the upper end in the vertical direction of the intermediate trough portion 434, at the front end Y2 in the front-rear direction Y of the intermediate trough portion 434, thereby being positioned at the most upstream side of the intermediate trough portion 434. The upstream end water receiving portion 4341 is positioned to protrude substantially horizontally in the front-rear direction Y2 from the upper end of the upright plate 431a that rises upward from the lower surface of the rear side Y1 of the first intermediate hollow portion 431 in the intermediate trough portion 434, at a position that avoids the fitting portion arrangement space opening 439 in a plan view.

[0060] The inclined portion 4342 is formed as a downward slope that descends from the rear end Y1 in the front-rear direction Y of the upstream end water receiving portion 4341, and from the front end Y2 in the front-rear direction Y towards the rear end Y1. The downstream end of the inclined portion 4342 is positioned in a location that avoids the fitting portion arrangement space opening 439 in a plan view. The inclined portion 4342 guides water that has entered the middle section gutter component 410 to the lower section gutter component 420 (lower water receiving portion). As a result, the middle section gutter component 410 is configured to guide water to the lower section gutter component 420 (lower water receiving portion) by the inclined portion 4342.

[0061] The downstream end projection 4343 is formed to protrude upward at the downstream end of the inclined section 4342 (in this embodiment, the rear end Y1). In a plan view, the downstream end projection 4343 is positioned to avoid the fitting space opening 439. In the middle section of the gutter 410, the downstream end projection 4343 and the downstream end of the inclined section 4342 allow water to accumulate at the downstream end of the inclined section 4342.

[0062] The intermediate gutter component 410, configured as described above, has the function of a gutter for water to flow and also functions as a water-stopping section. The intermediate gutter component 410 receives water that has passed through the bead material 401, which is the primary water-stopping structure, and guides the water to the lower gutter component 420, which is located on the downstream end side of the inclined section 4342, and distributes the water to both ends in the left-right direction X.

[0063] In the downstream gutter component 42 and intermediate component 43 configured as described above, when adjacent downstream gutter component 42 and intermediate component 43 are connected, the hooking engagement portion 428a of the downstream gutter component 42 is positioned inside the fitting portion arrangement space opening 439 of the adjacent intermediate component 43, and engages with the opposing protrusions 439a and 439b (rear lower protruding piece 436 and hooking piece 435b of the L-shaped hooking extension piece 435) to restrict vertical movement.

[0064] The L-shaped hook extension piece 435 has a downward extension piece 435a that extends downward from the middle of the inclined direction of the inclined portion 4342 of the middle section of the gutter 434, and a hook extension piece 435b that bends toward the front side Y2 from the lower end of the downward extension piece 435a. The hook extension piece 435b can engage with a hook engagement portion 428a formed at the other end of the downstream gutter component 42 adjacent to the rear side Y1. When engaged with the hook engagement portion 428a, the hook extension piece 435b can rotate around the hook engagement portion 428a.

[0065] When attaching an intermediate profile 43 adjacent to the front Y2 next to the downstream gutter profile 42, the intermediate profile 43 can be temporarily placed below the first beam 3 by hooking the hook extension piece 435 of the intermediate profile 43 onto the hook engagement portion 428a of the downstream gutter profile 42 to which the extension plate portion 32 of the first beam 3 is connected. Alternatively, with the hook extension piece 435 of the intermediate profile 43 hooked onto the hook engagement portion 428a of the downstream gutter profile 42, the intermediate profile 43 can be positioned at the attachment location by rotating the intermediate profile 43 around the tip of the hook extension piece 435.

[0066] When the intermediate profile 43 is positioned at the mounting location, the intermediate profile 43 is attached to the front side Y2 in the front-rear direction Y of the downstream gutter profile 42, with the hook extension piece 435 of the intermediate profile 43 fitted into the hook engagement portion 428a of the downstream gutter profile 42.

[0067] The front upper outward extension piece 437 and the front lower outward extension piece 438 of the intermediate profile 43 are similar in structure to the front upper outward extension piece 427 and the front lower outward extension piece 428 of the downstream gutter profile 42, insofar as they are not described. Therefore, the structure of the front upper outward extension piece 437 and the front lower outward extension piece 438 of the intermediate profile 43 is denoted by reference numerals corresponding to the structure of the downstream gutter profile 42 in Figure 8, and its explanation is omitted.

[0068] As shown in Figure 9, the roof structure 4 is waterproofed at the connection points between adjacent elongated members 41 by a bead material 401 that constitutes a primary waterproofing structure at the upper end. The roof structure also includes a middle gutter component 410 positioned in the middle and constituting a secondary waterproofing structure that receives water that could not be completely stopped by the bead material 401, and a lower gutter component 420 positioned in the lower part and constituting a tertiary waterproofing structure that receives water guided by the middle gutter component 410. The roof structure includes a two-tiered gutter structure consisting of the middle gutter component 410 and the lower gutter component 420. The middle gutter component 410 and the lower gutter component 420 are provided at the connection points between adjacent elongated members 41.

[0069] Furthermore, since the configurations of the multiple intermediate profiles 43 that are arranged in a row are all the same, their explanation will be omitted. As shown in Figure 8, when attaching an adjacent intermediate profile 43 next to an intermediate profile 43 connected to the first beam 3, the intermediate profile 43 can be temporarily placed below the first beam 3 by hooking the hook extension piece 435 of the intermediate profile 43 onto the hook engagement portion 438a of the intermediate profile 43 connected to the extension plate portion 32 of the first beam 3, similar to when attaching an intermediate profile 43 next to a downstream gutter configuration profile 42. In addition, with the hook extension piece 435 of the intermediate profile 43 hooked onto the hook engagement portion 438a of the intermediate profile 43, the intermediate profile 43 can be positioned at the attachment location by rotating the intermediate profile 43 around the hook extension piece 435. When adjacent intermediate profiles 43 are positioned at their mounting locations, the adjacent intermediate profiles 43 are attached to the front side Y2 of the intermediate profile 43 in the front-rear direction Y, with the hooking extension piece 435 of the adjacent intermediate profile 43 fitted into the hooking engagement portion 438a of the intermediate profile 43.

[0070] As shown in Figure 4, the upstream end profile 44 is arranged in parallel with the front end Y2 of the roof body 4 in the front-rear direction Y, where multiple long profiles 41 are lined up. In this embodiment, the upstream end profile 44 is formed from a long profile having a hollow structure with a hollow section. The configuration of the rear end Y1 of the upstream end profile 44 is the same as the configuration of the rear end Y1 of the intermediate profile 43. Therefore, the explanation of the upstream end profile 44 will be omitted by referring to the explanation of the intermediate profile 43.

[0071] As shown in Figure 1, the roof structure 4 has a pair of side frame members 45 (cover parts) positioned at both ends of the roof structure 4 in the left-right direction X. As shown in Figures 1 and 10, the pair of side frame members 45 extend in the front-rear direction Y of the roof structure 4 (a direction perpendicular (intersecting) to the longitudinal direction of the long profile 41) at both ends of the roof structure 4 in the left-right direction X.

[0072] As shown in Figure 10, the pair of side frame members 45 are formed at both ends of the roof body 4 in the left-right direction X, extending in the front-rear direction Y (intersecting direction) which intersects the left-right direction X from which the multiple elongated profiles 41 extend, and are arranged to cover the longitudinal ends of the elongated profiles 41. The side frame member 45 has an upper cover portion 451 (upper plate portion), a side cover portion 452 (vertically extending portion), and a lower side water receiving channel portion 453 (cover water-stopping portion).

[0073] The upper cover portion 451 is fixed to the upper surface of the roof body 4 by a plurality of screws 102 arranged in the front-rear direction Y of the roof body 4. An upper sealing member 451a is positioned between the lower surface of the upper cover portion 451 and the long profile 41.

[0074] The side cover portion 452 is formed extending in the vertical direction and is positioned on the outside of the sides of the longitudinal ends of the elongated profiles 41, facing the end faces of the multiple elongated profiles 41, so as to cover the left-right X ends of the roof body 4.

[0075] The lower water receiving channel section 453 is positioned below the lower surface 4b of both ends of the roof body 4 in the left-right direction X, and extends from the lower inner surface of the side cover section 452 toward the elongated profile 41. The lower water receiving channel section 453 is formed in a concave shape with the top open.

[0076] The lower water receiving channel section 453 receives and stops water flowing from the left-right ends of the roof body 4, allowing the water to circulate from the upstream side (front side Y2) to the downstream side (rear side Y1) of the roof body 4, and also functions as a water-stopping section to stop the water. The lower water receiving channel section 453 is formed in the side frame material 45 and extends in the front-rear direction Y along which the side frame material 45 extends, and receives water led out from the longitudinal end of the downstream end of the inclined portion 4342 of the middle gutter component 410 and the longitudinal end of the lower gutter component 420.

[0077] The water received by the lower water receiving channel section 453 flows downstream in the longitudinal direction Y, which is the end of the rear Y1 of the roof body 4. The water that has been carried downstream in the longitudinal direction Y of the roof body 4 by the lower water receiving channel section 453 falls downward at the end of the rear Y1 on the downstream side of the roof body 4. In addition, a portion of the water that has flowed over the upper surface of the lower water receiving channel section 453 is transmitted from the downstream end of the roof body 4 in the longitudinal direction Y to the drainage fins 425 (see Figure 7). From the drainage fins 425, the water transmitted from the lower water receiving channel section 453 falls downward to the roof body 4.

[0078] Next, the flow of rainwater in carport 1 will be explained. In carport 1 shown in Figure 1, rainwater falling on the upper surface 4a of the roof body 4 flows along the slope of the upper surface 4a of the roof body 4, from the upstream side to the downstream side in the direction of the slope of the roof body 4 (from the front side Y2 to the rear side Y1 in the front-to-back direction Y). The water that flows downstream of the roof body 4 then flows into the roof body side gutter component 40. The water that flows into the roof body side gutter component 40 then flows into the support column side gutter component 20 (see Figure 4).

[0079] Water that flows into the column-side gutter component 20 falls through the column-side gutter component 20 and is discharged to the outside of the first column 2 at the lower part of the first column 2.

[0080] Furthermore, rainwater falling on the upper surface 4a of the roof body 4 flows along the slope of the upper surface 4a of the roof body 4. In the multiple long profiles 41 that make up the roof body 4, bead material 401 is placed at the upper end of the connecting portion between adjacent long profiles 41, as shown in Figures 7 and 8. Therefore, the water flowing on the upper surface 4a of the roof body 4 can be stopped by the bead material 401, which acts as a primary water-stopping structure, at the upper end of the connecting portion between adjacent long profiles 41. By stopping the water flow with the bead material 401, it is possible to prevent water flowing on the upper surface 4a of the roof body 4 from penetrating into the interior of the roof body 4 from the connecting portion between the long profiles 41.

[0081] Furthermore, even if water seeps into the interior of the roof body 4 from the area where the bead material 401 is placed at the upper end of the connecting portion between adjacent long profiles 41, the interior of the roof body 4 is provided with a middle gutter component 410 and a lower gutter component 420 in a stepped manner in two consecutive stages, forming a double watertight seal. Therefore, water seeping into the interior of the roof body 4 from the area where the bead material 401 is placed at the upper end of the connecting portion between adjacent long profiles 41 flows into the middle gutter component 410, which is the second watertight seal. The water that flows into the middle gutter component 410 flows to the downstream end of the inclined portion 4342 of the middle gutter component 410 and is guided towards the lower gutter component 420. The water that overflows from the middle gutter component 410 flows into the lower gutter component 420, which is the tertiary watertight seal. The two-tiered gutter structure, consisting of the middle gutter component 410 and the lower gutter component 420, allows water to flow and stop along the direction in which the connecting portion of adjacent long profile members 41 extends, that is, along the longitudinal direction of the long profile member 41. This further suppresses water from falling from the lower surface 4b of the roof body 4.

[0082] Water introduced into the middle gutter section 410 and the lower gutter section 420 flows toward the left-right ends of the roof body 4. The water that has flowed toward the left-right ends of the roof body 4 is introduced into the side frame members 45 (see Figure 10) provided at both ends of the roof body 4 in the left-right direction X.

[0083] In this embodiment, as shown in Figure 9, water that enters the middle section of the gutter 410 is guided towards the lower section of the gutter 420 by the inclined portion 4342. The upstream end water receiving portion 4341 is positioned to protrude substantially horizontally to the front Y2 in the front-rear direction Y, avoiding the fitting portion arrangement space opening 439 in a plan view, and the inclined portion 4342 guides the water towards the lower section of the gutter 420. Therefore, the water flowing through the downstream end of the inclined portion 4342 of the middle section of the gutter 410 and the lower section of the gutter 420 is introduced into the side frame material 45 from both longitudinal ends of the downstream end of the inclined portion 4342 of the middle section of the gutter 410 and both longitudinal ends of the lower section of the gutter 420, at a position in the front-rear direction Y that avoids the position of the fitting portion arrangement space opening 439 formed below the connecting portion between adjacent elongated profiles 41. Therefore, it is possible to suppress the introduction of water into the side frame material 45 at the fitting portion of the connecting part between adjacent long profiles 41, and to suppress the dripping of water from the joint portion 46 of the lower fitting portion of the connecting part between adjacent long profiles 41 at both ends of the long profiles 41 in the left-right direction X.

[0084] Water introduced into the side frame member 45 is received by the lower water receiving channel section 453 (see Figure 10) (water-stopping section) located at the lower end of the side frame member 45, and flows along the slope of the roof body 4 to the rear side Y1 on the downstream side in the front-rear direction Y of the roof body 4. The water that flows towards the first support column 2 side in the lower water receiving channel section 453 of the side frame member 45 flows to the rear side Y1 on the downstream side of the roof body 4, and falls downward from the end of the rear side Y1 on the downstream side of the roof body 4.

[0085] A portion of the water that flows downstream in the lower water receiving channel section 453 of the side frame material 45 is transmitted from the downstream end of the roof body 4 to the water drainage fin 425 (see Figure 7), which is provided protruding downward from the lower end of the downstream gutter component 42 of the roof body 4, and falls downward via the water drainage fin 425.

[0086] The embodiment described above provides the following effects. In this embodiment, the roof body 4 has a middle gutter component 410 positioned in the middle of the vertical direction and having a downward sloping section 4342 at the connection point between adjacent long profiles 41, and a lower gutter component 420 positioned in the lower of the vertical direction. The sloping section 4342 guides water that has entered the middle gutter component 410 towards the lower gutter component 420. As a result, water that has entered the middle gutter component 410 is guided to a position that avoids the fitting portion of the connection point between adjacent long profiles 41, thereby suppressing water from dripping from the fitting portion of the connection point between adjacent long profiles 41 and improving water-stopping performance.

[0087] Furthermore, in this embodiment, a downstream end projection 4343 that protrudes upward is formed at the downstream end of the inclined portion 4342 of the middle section gutter component 410, and water can be stored at the downstream end of the inclined portion 4342 by the inclined portion 4342 and the downstream end projection 4343. As a result, by storing water at the downstream end of the inclined portion 4342, it functions as a gutter that stores and drains water at the downstream end of the inclined portion 4342 at a position that avoids the fitting portion of the connecting portion between adjacent long profiles 41, and also functions as a water-stopping section, thereby improving water-stopping performance.

[0088] Furthermore, in this embodiment, a fitting space opening 439 is formed below the middle section of the gutter 410, where fitting portions of connecting adjacent elongated profiles 41 are arranged. The downstream end of the inclined section 4342 is positioned to avoid the fitting space opening 439 in a plan view. As a result, when water flows to the downstream end of the inclined section 4342, the water can be guided to the downstream end of the inclined section 4342, which is positioned to avoid the fitting space opening 439, thereby improving water-stopping performance.

[0089] Furthermore, in this embodiment, a fitting space opening 439 is formed below the middle section gutter component 410, where fitting portions of connecting parts between adjacent elongated profiles 41 are arranged. The middle section gutter component 410 is formed straddling the fitting space opening 439 and extends to the outside of the fitting space opening 439 in the width direction. This allows the downstream end of the inclined portion 4342 of the middle section gutter component 410 to be positioned to avoid the fitting space opening 439, and water can be guided to the downstream end of the inclined portion 4342, thereby improving water-stopping performance.

[0090] Furthermore, in this embodiment, a bead material 401 is placed at the upper end of the connecting portion between adjacent long profiles 41, which is positioned between adjacent long profiles. This prevents water flowing on the upper surface 4a of the roof body 4 from penetrating into the interior of the roof body 4.

[0091] Furthermore, in this embodiment, the structure includes side frame members 45 formed to extend in intersecting directions that intersect the directions in which the multiple elongated profiles 41 extend, and arranged to cover the longitudinal ends of the elongated profiles 41. The side frame members 45 have a lower water receiving channel section 453 formed thereon, which extends in the direction in which the side frame members 45 extend and receives water discharged from the longitudinal end of the downstream end of the middle section 410 and the longitudinal end of the lower section 420. As a result, the water-stopping performance can be improved by receiving and distributing water discharged from the longitudinal end of the downstream end of the middle section 410 and the longitudinal end of the lower section 420 through the lower water receiving channel section 453.

[0092] Furthermore, the carport 1 of this embodiment includes a first support column 2, a first beam 3 connected to the first support column 2 and extending in the front-rear direction Y which intersects the direction in which the first support column 2 extends, a roof body 4 directly or indirectly connected to the first beam 3, and a second support column 5 positioned to the side of the end of the roof body 4 in the left-right direction X which intersects the front-rear direction Y in which the first beam 3 extends, and directly or indirectly connected to the side surface of the first beam 3. This allows the position of the second support column 5 to be placed at a distance from the left-right direction X of the roof body 4, thereby improving the degree of freedom in the position where the second support column 5 is installed.

[0093] Furthermore, this embodiment includes a second beam 6 that connects the first beam 3 and the second support column 5. This allows for a simple configuration of the connection between the first beam 3 and the second support column 5. Also, because the connection between the first beam 3 and the second support column 5 is simple, construction of the connection between the first beam 3 and the second support column 5 can be easily carried out.

[0094] Furthermore, in this embodiment, the first beam 3 is positioned above the roof structure 4. The second beam 6 is positioned above the roof structure 4, to the side of the first beam 3. The outer end of the second beam 6 in the left-right direction X is connected to the second support column 5, and the inner end of the second beam 6 in the left-right direction X is connected to the side surface of the first beam 3. This makes it possible to easily configure the connection between the side surface of the first beam 3 and the second support column 5.

[0095] Furthermore, in this embodiment, the roof body 4 is formed with a downward slope from the side away from the first support column 2 towards the side towards the first support column 2. This makes it possible to realize a carport 1 having a roof body 4 with a front-to-back slope that slopes downward from the front side Y2 to the rear side Y1 in the front-to-back direction Y, with a simple configuration.

[0096] Furthermore, in this embodiment, the second support column 5 and the second beam 6 can be installed at any position in the front-to-back direction Y along which the first beam 3 extends. This improves the degree of freedom in the position where the second support column 5 is installed.

[0097] The configuration of the first embodiment has been described above. However, the configuration is not limited to the above embodiment. Next, an embodiment different from the first embodiment will be described with reference to the drawings.

[0098] [Second Embodiment] As shown in Figure 11, the carport 1A (roof structure) of the second embodiment further comprises a pair of second support columns 5A and a pair of second beams 6A, in addition to the pair of second support columns 5 and a pair of second beams 6 of the carport 1 (roof structure) of the first embodiment shown in Figure 1.

[0099] As shown in Figure 11, the carport 1A of the second embodiment includes a pair of second support columns 5 and a pair of second beams 6 positioned near the front Y2 side of the roof body 4 in the front-rear direction Y, and a pair of second support columns 5A and a pair of second beams 6A positioned near the rear Y1 side of the roof body 4 in the front-rear direction Y, with two sets of pairs of second support columns 5, 5A and pairs of second beams 6, 6A arranged along the front-rear direction Y on which the first beam 3 extends.

[0100] The pair of second support columns 5A are positioned on the sides of the roof body 4 in the left-right direction X, near the rear Y1 of the roof body 4 in the front-rear direction Y. The second beam 6A extends from the upper end of the second support columns 5A toward the first beam 3. Thus, both sides of the roof body 4 in the left-right direction X are supported by two pairs of second support columns 5, 5A and a pair of second beams 6, 6A.

[0101] In the second embodiment, the configuration other than the pair of second support columns 5A and the pair of second beams 6A is the same as in the first embodiment. In the second embodiment, the structure for connecting the second beam 6A to the second support columns 5A and the side surface of the first beam 3 is the same as the structure for connecting the second beam 6 to the second support columns 5 and the side surface of the first beam 3 in the first embodiment. Furthermore, the configuration of the roof body 4 and the waterproofing structure of the roof body 4 in the second embodiment are the same as the configuration of the roof body 4 and the waterproofing structure of the roof body 4 in the first embodiment.

[0102] According to the second embodiment, the roof body 4 is supported on both sides in the left-right direction X by two pairs of second support columns 5, 5A and a pair of second beams 6, 6A, thus providing stable support for the roof body 4. In this embodiment, the roof body 4 is supported by two pairs of second support columns 5, 5A and a pair of second beams 6, 6A, but the embodiment is not limited to this, and the roof body 4 may be supported by three or more pairs of second support columns 5, 5A and a pair of second beams 6, 6A.

[0103] [Third Embodiment] As shown in Figure 12, the carport 1B (roof structure) of the third embodiment differs from the first embodiment in that the position where the second support column 5B, which is located on one side in the left-right direction X of the pair of second support columns 5 of the carport 1 (roof structure) of the first embodiment shown in Figure 1, is installed, and the length of the second beam 6B, which is located on one side in the left-right direction X of the pair of second beams 6.

[0104] As shown in Figure 12, in the third embodiment, the second support column 5B is positioned further outward in the left-right direction X of the roof body 4 than the position where the second support column 5 is positioned in the first embodiment. The second beam 6B is formed extending longitudinally outward from the outside of the roof body 4 and extends further outward in the left-right direction X than the second beam 6 in the first embodiment.

[0105] In the third embodiment, the configuration other than the second support column 5B and the second beam 6B is the same as in the first embodiment. In the third embodiment, the structure connecting the second beam 6B to the second support column 5B and the side surface of the first beam 3 is the same as the structure connecting the second beam 6 to the second support column 5 and the side surface of the first beam 3 in the first embodiment. Furthermore, the configuration of the roof body 4 and the waterproofing structure of the roof body 4 in the third embodiment are the same as the configuration of the roof body 4 and the waterproofing structure of the roof body 4 in the first embodiment.

[0106] According to the third embodiment, by configuring the second beam 6B to extend longitudinally to the outside of the roof body 4, the position of the second support column 5B can be positioned at a location far to the outside in the left-right direction X of the roof body 4, thereby improving the degree of freedom in the position where the second support column 5B is installed.

[0107] In this embodiment, the second support column 5B located on one side of the roof body 4 in the left-right direction X is positioned at a distance from the outside of the roof body 4 in the left-right direction X, and the second beam 6B is extended outwards from the roof body 4 in the left-right direction X, but the embodiment is not limited to this. The second support column 5 located on the other side of the roof body 4 in the left-right direction X may be positioned at a distance from the outside of the roof body 4 in the left-right direction X, and the second beam 6 may be extended outwards from the roof body 4 in the left-right direction X. Alternatively, the second support columns may be positioned at a distance from the outside of the roof body 4 in the left-right direction X on both sides of the roof body 4 in the left-right direction X, and the second beam may be extended outwards from the roof body 4 in the left-right direction X.

[0108] [Fourth Embodiment] As shown in Figure 13, the carport 1C (roof structure) of the fourth embodiment differs from the carport 1 (roof structure) of the first embodiment shown in Figure 1 in that the first support column 2C and the first beam 3C are positioned closer to the left-right direction X end of the roof body 4 than the first support column 2 and the first beam 3 of the first embodiment, and the length of the left-right direction X of the second beam 6C, which is positioned outside the left-right direction X of the first beam 3C, is shorter than the length of the second beam 6 of the first embodiment.

[0109] As shown in Figure 13, in the fourth embodiment, the first support column 2C and the first beam 3C are positioned further outward in the left-right direction X of the roof body 4 than in the positions where the first support column 2 and the first beam 3 are positioned in the first embodiment. The second support column 5 is positioned in the same position as the second support column 5 in the first embodiment. The second beam 6C is configured such that the length in the left-right direction X between the second support column 5 and the side surface of the first beam 3C is shorter than that of the second beam 6 in the first embodiment.

[0110] In the fourth embodiment, the configuration other than the first support column 2C, the first beam 3C, and the second beam 6C is the same as in the first embodiment. In the fourth embodiment, the structure connecting the second beam 6C to the second support column 5 and the side surface of the first beam 3C is the same as the structure connecting the second beam 6 to the second support column 5 and the side surface of the first beam 3 in the first embodiment. Furthermore, the configuration of the roof body 4 and the waterproofing structure of the roof body 4 in the fourth embodiment are the same as the configuration of the roof body 4 and the waterproofing structure of the roof body 4 in the first embodiment.

[0111] According to the fourth embodiment, even when the first support column 2C is positioned further outward in the left-right direction X of the roof body 4 than the position where the first support column 2 is positioned in the first embodiment, a structure can be realized in which the side surface of the first beam 3C and the second support column 5 are connected via the second beam 6C. Therefore, the degree of freedom in the position where the first support column 2C is installed can be improved. Note that the length of the second beam 6C in the left-right direction X is not limited to the length of the first or fourth embodiment, but can be set as appropriate.

[0112] [Fifth Embodiment] As shown in Figure 14, the carport 1D (roof structure) of the fifth embodiment differs from the first embodiment shown in Figure 1 in that, while the inner ends of a pair of second beams 6 in the left-right direction X are connected to the sides of a pair of first beams 3, in the fifth embodiment the upper ends of a pair of second support columns 5D are located above the upper ends of a pair of second support columns 5 in the first embodiment, and one second beam 6D is arranged above the pair of first beams 3, extending across the left-right direction X of the roof body 4, and one second beam 6D is connected to the sides of the pair of first beams 3. The configuration of the roof body 4 and the waterproofing structure of the roof body 4 of the fifth embodiment are the same as those of the roof body 4 and the waterproofing structure of the roof body 4 of the first embodiment.

[0113] The carport 1D of the fifth embodiment includes, in place of the pair of second support columns 5 and pair of second beams 6 of the carport 1 of the first embodiment, a pair of second support columns 5D whose upper end length is longer than that of the second support columns 5 of the first embodiment, and a second beam 6D that connects the upper ends of the pair of second support columns 5D and extends in the left-right direction X.

[0114] As shown in Figure 14, in the fifth embodiment, similar to the first embodiment, the first beam 3 is positioned above the roof body 4. On the other hand, in the fifth embodiment, the second beam 6D is positioned above the roof body 4 and above the first beam 3, and extends in the left-right direction X, which intersects the front-rear direction Y in which the first beam 3 extends. In this embodiment, the second beam 6D is positioned on the upper surface of the first beam 3.

[0115] As shown in Figures 15 to 17, both ends (first portion) of the second beam 6D in the left-right direction X are connected to a pair of second support columns 5D. The lower surface of the middle portion (second portion) of the second beam 6D in the left-right direction X is connected to the sides of a pair of first beams 3 by a pair of L-shaped brackets 63 and 64 (mounting brackets) in the middle of the left-right direction X.

[0116] At the connection point between the middle of the second beam 6D in the left-right direction X and the side surface of the first beam 3, as shown in Figure 15, the L-shaped bracket 63 is positioned on the outside of the first beam 3 in the left-right direction X, and the L-shaped bracket 63 is positioned on the inside of the first beam 3 in the left-right direction X.

[0117] As shown in Figures 15 and 16, the L-shaped bracket 63 is formed in an L-shape and positioned on the outside of the first beam 3 in the left-right direction X, straddling the outer side surface of the first beam 3 in the left-right direction X and the lower surface of the second beam 6D midway along the left-right direction X. The L-shaped bracket 63 has a plate-shaped first fixing plate 631 that runs along the outer side surface of the first beam 3 in the left-right direction X, and a plate-shaped second fixing plate 632 that is formed by bending outward in the left-right direction X from the upper end of the first fixing plate 631 and runs along the lower surface of the second beam 6D. The first fixing plate 631 is screw-fixed to the outer side surface of the first beam 3 in the left-right direction X. The second fixing plate 632 is screw-fixed to the lower surface of the second beam 6D.

[0118] As shown in Figures 15 and 17, the L-shaped bracket 64 is formed in an L-shape and positioned on the inside of the first beam 3 in the left-right direction X, straddling the inside side surface of the first beam 3 in the left-right direction X and the lower surface of the second beam 6D midway along the left-right direction X. The L-shaped bracket 64 has a plate-shaped first fixing plate 641 that follows the inside side surface of the first beam 3 in the left-right direction X, and a plate-shaped second fixing plate 642 that is formed by bending inward in the left-right direction X from the upper end of the first fixing plate 641 and follows the lower surface of the second beam 6D. The first fixing plate 641 is screw-fixed to the outside side surface of the first beam 3 in the left-right direction X. The second fixing plate 642 is screw-fixed to the lower surface of the second beam 6D.

[0119] In the fifth embodiment, the side surface of the first beam 3 and the second beam 6 are connected by L-shaped brackets 63 and 64, but the embodiment is not limited to this.

[0120] [Sixth Embodiment] As shown in Figures 19 and 20, the carport 1E (roof structure) of the sixth embodiment differs from the carport 1 (roof structure) of the first embodiment in the support structure of the roof body 4. The carport 1E of the sixth embodiment is a carport with a double support structure. In the description of the sixth embodiment, the direction in which the beam 3E of the carport 1E extends is also referred to as the left-right direction A. The direction that intersects the direction in which the beam 3E extends, and in which the multiple long profiles 41 (long members) constituting the roof body 4 extend, is also referred to as the front-back direction B. Components similar to those of the first embodiment may be given the same reference numerals and their description may be omitted.

[0121] As shown in Figures 19 and 20, the carport 1E of the sixth embodiment is a so-called double-supported carport (double-supported structure) in which the roof body 4 is supported by a pair of support columns 2E on each side in the left-right direction A. Furthermore, the carport 1E of this embodiment is configured as a suspension structure in which the roof body 4 is suspended and connected to the lower part (below) of the beam 3E connected to the support columns 2E. The configuration of the roof body 4 of the carport 1E of the sixth embodiment is the same as the configuration of the roof body 4 of the carport 1 of the first embodiment.

[0122] As shown in Figure 18, the carport 1E of the sixth embodiment comprises two pairs of support columns 2E erected on the ground, two beams 3E extending from the upper ends of the support columns 2E in a direction intersecting the support columns 2E, and a roof body 4 connected to the lower part of the two beams 3E. Similar to the first embodiment, the support columns 2E and beams 3E are formed from extruded aluminum profiles and have a hollow structure with a hollow cross-section.

[0123] As shown in Figure 19, the two pairs of support columns 2E are arranged side by side in the front-to-back direction B. The pairs of support columns 2 are positioned opposite each other on the outside of both ends of the carport 1E in the left-to-right direction A, with the roof body 4 in between, and are connected to both ends of the beam 3E in the left-to-right direction A.

[0124] The two beams 3E are positioned apart in the front-to-back direction B of the carport 1E. Each of the two beams 3E connects the upper ends of a pair of support columns 2E and extends in the left-to-right direction A of the roof body 4. Both beams 3E are formed with a downward slope in the left-to-right direction A, decreasing from one side A2 to the other side A1. The upper ends of the support columns 2E are positioned outside both ends of the two beams 3E in the left-to-right direction A. The roof body 4 is connected to the lower parts of the pair of beams 3E.

[0125] The configuration of the roof body 4 in the sixth embodiment is the same as that of the roof body 4 in the first embodiment. In the sixth embodiment, the direction of inclination of the roof body 4 is different from that of the first embodiment. While the roof body 4 in the first embodiment was formed with a downward slope that descends from the front side Y2 to the rear side Y1 in the front-rear direction B, the roof body 4 in the sixth embodiment is formed with a downward slope in the left-right direction A, from the other side A2 to the one side A1. The roof body 4 is a suspended structure that is suspended and arranged below the two beams 3E, and is connected to the lower part of the two beams 3E. The connection structure between the roof body 4 and the pair of beams 3E is the same as in the first embodiment.

[0126] Similar to the first embodiment, the roof structure 4 is constructed by connecting a plurality of long profiles (long members) 41 in a row in the direction in which the beam 3E extends, and fitting them together. Each of the plurality of long profiles 41 extends in the front-to-back direction B of the carport 1E (a direction perpendicular to the direction in which the beam 3E extends).

[0127] Each of the multiple elongated profiles 41 is formed from an extruded aluminum profile and has a hollow structure with a hollow section formed in a hollow cross-section. The roof body 4 has a flat (planar) upper surface 4a and a flat lower surface 4b.

[0128] The multiple elongated profiles 41 constituting the roof body 4 are configured, as in the first embodiment shown in Figure 4, as shown in Figure 20, with a downstream gutter configuration profile 42 positioned at the downstream end, an upstream end profile 44 positioned at the upstream end, and a plurality of intermediate profiles 43 positioned between the downstream gutter configuration profile 42 and the upstream end profile 44, in the left-right direction A.

[0129] The configuration of the multiple elongated profiles 41 (downstream gutter configuration profiles 42, intermediate profiles 43, and upstream end profiles 44) constituting the roof body 4 in the sixth embodiment is the same as the configuration of the multiple elongated profiles 41 (downstream gutter configuration profiles 42, intermediate profiles 43, and upstream end profiles 44) constituting the roof body 4 in the first embodiment. In the roof body 4, the bead material 401 constituting the first waterproofing structure, the middle gutter configuration 410 constituting the second waterproofing structure, and the lower gutter configuration 420 constituting the tertiary waterproofing structure are also the same as in the first embodiment. The roof body 4 of the sixth embodiment also has the same waterproofing structure as in the first embodiment and has the same waterproofing performance as the roof body 4 of the first embodiment.

[0130] Although a preferred embodiment of the roof structure of this disclosure has been described above, this disclosure is not limited to the embodiment described above and can be modified as appropriate.

[0131] For example, in the first to fifth embodiments, the second support column is indirectly connected to the side surface of the first beam by connecting it to the side surface of the first beam via the second beam, but the invention is not limited to this. The first support column and the first beam may be placed at the left-right end X of the roof body 4, and the second support column may be directly fixed to the side surface of the first beam without going through the second beam.

[0132] Furthermore, in the first to fourth embodiments, the side surface of the first beam 3 and the second beams 6, 6B, and 6C are connected by L-shaped brackets 61 and 62, but the invention is not limited to this. For example, as shown in Figures 18A and 18B, the side surface of the first beam 3 and the second beam 6 may be connected by a bracket 65 placed inside the tip of the second beam 6, with a backing plate member 33 placed inside the first beam 3. Specifically, as shown in Figures 18A and 18B, a cylindrical backing plate member 33 is placed inside the first beam 3 at a position corresponding to the connection portion between the side surface of the first beam 3 and the second beam 6. In this state, the U-shaped bracket 65 is placed inside the tip of the second beam 6 with the outer surface of the closed side of the U-shape of the bracket 65 facing the side of the first beam 3. The closed side plate portion 651 of the U-shape of the bracket 65 is fixed to the side of the first beam 3 by screws 601 that pass through the plate portion 651 of the bracket 65, the side of the first beam 3, and the plate portion of the backing plate member 33 placed inside the first beam 3 in this order, and the pair of open side plates 652 of the U-shape of the bracket 65 are fixed to the second beam 6 by screws 602. In this way, by placing the backing plate member 33 inside the first beam 3 and connecting the side of the first beam 3 and the second beam 6 with the bracket 65, the side of the first beam 3 and the second beam 6 can be connected without exposing mounting hardware such as L-shaped brackets as in the first to fourth embodiments to the outside.

[0133] Furthermore, in the first embodiment described above, the connecting member 21 connecting the first support column 2 and the first beam 3 was formed in an L-shape, but is not limited to this. The shape of the connecting member is not limited, and for example, the connecting member may be made of a T-shaped member and placed inside the first support column 2 and the first beam 3, with the connecting member connecting the first support column 2 and the first beam 3.

[0134] Furthermore, in the above embodiment, the roof body 4 was directly connected (fixed) to the first beam 3 below the first beam 3, but the invention is not limited to this, and the roof body 4 may be indirectly connected (fixed) to the first beam 3 via other members.

[0135] Furthermore, in the above embodiment, the roof body 4 is configured to be suspended from the first beam 3, but it is not limited to this, and may be configured as an upper-mounted structure positioned above the first beam 3. If the roof body 4 is configured as an upper-mounted structure positioned above the first beam 3, for example, the second beam may be positioned below the first beam so that the second beam is connected to the lower surface of the first beam.

[0136] Furthermore, in the first to fifth embodiments, the roof body 4 is configured to be inclined in the front-rear direction Y, but the invention is not limited to this, and the roof body 4 may also be configured to be inclined in the left-right direction X.

[0137] Furthermore, although the sixth embodiment described the case in which the roof body 4 is applied to a carport 1E (roof structure) with a double-support structure, it is not limited to this. The roof body 4 may also be applied to a carport (roof structure) with a single-support structure.

[0138] Furthermore, in the sixth embodiment, the roof body 4 is configured to be inclined in the left-right direction A, but the invention is not limited thereto, and the roof body 4 may be configured to be inclined in the front-rear direction B. Also, in the first to fifth embodiments, among the plurality of long profiles 41 (long members) constituting the roof body 4, the intermediate profile 43 (long member) and the upstream end profile 44 (long member) are configured as hollow structures having a hollow portion, but the invention is not limited thereto, and they may be configured as solid structures with no upper surface portion of the hollow portion and the upper side open.
