Description

Technical Field

[0001] The present invention relates to a roof structure including a column member, a beam, and a roof body, and a method for constructing the roof structure.

Background Art

[0002] Conventionally, a carport (roof structure) having a cantilever support structure including a column member, a beam connected to the column member, and a roof body connected to the beam has been known (see, for example, Patent Document 1). The roof body of the carport described in Patent Document 1 is composed of a framed frame (frame body) and a panel material disposed inside the frame. In addition, a carport including a column member, a beam connected to the column member, a roof body connected to the beam, and a ceiling material disposed below the roof body and having a flat lower surface has been known (see, for example, Patent Document 2). The ceiling material described in Patent Document 2 is disposed below the roof body so that the lower surface of the roof body is not visible.

Summary of the Invention

Problems to be Solved by the Invention

[0004] Since the roof body of the carport described in Patent Document 1 is composed of a frame and a panel material, the frame is thicker than the panel material, and the unevenness of the frame and the panel material is in a state where it can be visually recognized from the outside. Therefore, it is desired to improve the design property. Further, in the carport described in Patent Document 1, when attaching the panel material to the frame at the construction site of the carport, the panel material is large and difficult to handle. Therefore, it is desired to improve the construction of the roof body. In addition, in the carport described in Patent Document 2, a ceiling material with a flat lower surface is arranged below the roof body in which a panel material is attached to the frame, and a double structure is formed between the roof body and the ceiling material. In the carport described in Patent Document 2, since the roof portion has a double structure of a roof body and a ceiling material, the number of parts increases and the structure tends to become complicated. Therefore, the manufacturing cost increases and the construction of the roof portion tends to be laborious. Therefore, a carport (roof structure) that can improve the design property and the constructability is desired.

[0005] An object of the present invention is to provide a roof structure and a construction method of the roof structure that can improve the design property and the constructability.

Means for Solving the Problems

[0006] The present invention relates to a column member (for example, a support column 2 described later), a beam (for example, a beam 4 described later) connected to the column member, and a roof body (for example, the one described later) connected to the beam, the roof body having a plurality of long members (for example, long-shaped members 61 described later) arranged side by side in a predetermined direction and having a lower surface (for example, a lower surface 6b described later) formed in a planar shape (for example, a roof body 6 described later), and relates to a roof structure (for example, a carport 1 described later).

[0007] Further, it is preferable that the plurality of long members are arranged side by side in the direction in which the beam extends.

[0008] Further, it is preferable that each of the plurality of long members is directly fixed to the beam.

[0009] Further, it is preferable that the roof body is suspended and arranged below the beam.

[0010] Further, among the plurality of long members, the first long member (for example, the gutter forming member 62 and the intermediate member described later) attached to the beam is disposed on one end side in the width direction orthogonal to the longitudinal direction, and has a first engaging portion (for example, the engaging portions 628a and 638a described later). Among the plurality of long members, the second long member (for example, the intermediate member described later) attached to the beam adjacent to the first long member is disposed on the end side on the first long member side in the width direction orthogonal to the longitudinal direction, and preferably has a second engaging portion that can engage with the first engaging portion and is rotatable about the first engaging portion.

[0011] Further, the second long member preferably has a screw fixing portion (for example, the nut member 601 described later) disposed on the end side opposite to the second engaging portion in the width direction orthogonal to the longitudinal direction and fixable to the beam from above with a screw member (for example, the screw member 101 described later).

[0012] Further, the long member is preferably composed of a shaped member of an aluminum material having a hollow structure with a hollow portion.

[0013] Further, the upper surface of the roof body (for example, the upper surface 6a described later) is preferably formed in a flat shape.

After the arranging step, at the end side opposite to the second engaging portion in the width direction orthogonal to the longitudinal direction, a fixing step of fixing the screw fixing portion of the second long member to the beam from above with a screw member is preferably provided.

[0016] Further, it is preferable to include a step of attaching the plurality of long members to the beam in order from the column member side.

[0019] Hereinafter, a first embodiment of the roof structure of the present invention will be described with reference to the drawings. In this embodiment, an example in which the roof structure is applied to the carport 1 will be described. Note that, in this embodiment, an example in which the roof structure is applied to the carport 1 is described, but the present invention is not limited thereto. For example, the roof structure may be applied to structures other than the carport, such as structures such as a bicycle parking lot, a shelter, a rest area, a terrace, and a bus stop.

[0021] In the description of this embodiment, the direction in which a plurality of long members (long members) 61 constituting the roof body 6 of the carport 1 extend is also referred to as the front-rear direction. In FIGS. 1 and 2, the front side of the carport 1 is also referred to as the front side, and the back side of the carport 1 is also referred to as the back side. Further, the direction orthogonal to the front-rear direction in which the long member (long member) 61 extends is also referred to as the left-right direction. Also, in the left-right direction, when viewed from the front side, the column 2 side is also referred to as the right side of the carport 1, and when viewed from the front side, the side opposite to the column 2 is also referred to as the left side of the carport 1. Further, in the direction in which the beam 4 extends, the column 2 side is also referred to as the base end side of the carport 1, and the side opposite to the column 2 is also referred to as the tip side of the carport 1.

[0022] First, the overall structure of the carport 1 of the present embodiment will be described. As shown in FIGS. 1 and 2, the carport 1 of the present embodiment is a so-called cantilevered carport in which a roof body 6 is supported by a pair of columns 2 on the base end side in the left-right direction (the right side in FIGS. 1 and 2). Further, the carport 1 of the present embodiment is configured by a suspension structure in which the roof body 6 is suspended and connected to the lower part (below) of a beam 4 connected to the column 2.

[0023] As shown in FIGS. 1 to 6, the carport 1 of the present embodiment includes a pair of columns 2 (column members) erected on the ground 11, a column cover member 3 (cover member) attached to the side surfaces of the pair of columns 2, a beam 4 extending from the upper end portion of the column 2 in a direction intersecting the column, an L-shaped connecting member 5 connecting the column 2 and the beam 4, a roof body 6 connected to the lower part of the beam 4, an L-shaped guiding member 7 (see FIG. 3) for guiding the water flowing on the upper surface of the roof body 6 to the column 2 side, a pair of roof body side cover members 8 (cover parts), and a roof body tip cover member 65. The column 2 and the beam 4 are formed of extruded profiles of aluminum material and have a hollow structure having a hollow portion with a hollow cross section.

[0024] As shown in FIG. 1, the pair of columns 2 are arranged at intervals in the front-rear direction of the carport 1 on one side in the left-right direction of the carport 1 (the right side in FIG. 1). The column 2 is formed to extend in the vertical direction and, as shown in FIG. 7, has a hollow column-side hollow portion 21 formed with a square tube-shaped cross section, and a pair of cover mounting walls 22 protruding toward the roof body 6 side from the side surface of the column-side hollow portion 21 on the roof body 6 side and extending in the vertical direction. The column cover member 3 is attached to the pair of cover mounting walls 22. A column cap 201 is arranged at the upper end portion of the column 2 so as to cover the opening at the upper end portion of the column 2.

[0025] As shown in FIG. 1, at one side in the front-rear direction (the front side in FIG. 1) of the pair of columns 2, a lower end opening 23 is formed at the lower end near the ground 11. The lower end opening 23 has a side surface on the roof body 6 side open and is cut out so as to be recessed from the roof body 6 side toward the inside of the column 2. A drain receiving lid member 24 is disposed in the lower end opening 23. The drain receiving lid member 24 is provided with a discharge opening 24a that opens outward toward the front side in the front-rear direction. The discharge opening 24a discharges the water flowing through the column side gutter component 20 (described later) constituted by the column 2 and the column cover member 3 to the outside on the front side.

[0026] As shown in FIG. 4, the column cover member 3 is attached to a pair of cover attachment walls 22 of the column 2. The column cover member 3 is constituted by a single cover member extending in the vertical direction. The column cover member 3 is attached to a pair of cover attachment walls 22 (see FIG. 7) so as to cover one side surface of the column 2 on the roof body 6 side and a screw member 102 for fixing the column 2 and the connecting member 5 described later. That is, the column cover member 3 is constituted by a single cover member without being divided, and is disposed so as to cover the four screw members 102 that fix only one side surface of the connecting member 5 on only one side surface of the column 2. Since water flowing on the upper surface 6a of the roof body 6 flows into the space between the column 2 and the column cover member 3 and the water flows, the column 2 and the column cover member 3 are configured as a column side gutter component 20 (column material side gutter structure). In the present embodiment, no hose for a rain gutter or the like is disposed between the column 2 and the column cover member 3, and only the column 2 and the column cover member 3 constitute a vertical gutter.

[0027] The water discharged from the roof body side gutter component 60 (described later) of the roof body 6 flows into the space between the column 2 and the column cover member 3 (column side gutter component 20). Since the side surface of the column 2 on the roof body 6 side of the column side gutter component 20 is covered by the column cover member 3, it is not visible from the outside of the carport 1. Therefore, it is not visible from the outside that the column 2 has the function of a gutter, and the design can be improved.

[0028] As shown in Fig. 1, a pair of beams 4 are arranged at intervals in the front - rear direction of the carport 1. The pair of beams 4 each extend in the left - right direction and are formed with a downward slope that slopes downward toward the column 2 side. The end portion (right - hand end portion) on the proximal - end side of the pair of beams 4 is connected to the upper - end portion of the column 2 via an L - shaped connecting member 5. A roof body 6 is connected to the lower part of the pair of beams 4.

[0029] As shown in Figs. 1 and 4, each of the pair of beams 4 has a beam - side hollow portion 41 with a square - tube - shaped cross - section, an extension plate portion 42, and an end cap 43.

[0030] The tip 41a of the beam - side hollow portion 41 is formed with an upward slope that rises from the tip side toward the proximal - end side (column 2 side) such that the upper - end portion on the tip side is inclined and notched. Therefore, in a state where the roof body 6 is connected to the lower part of the beam 4, the tip 41a of the beam 4 has a shape that is difficult to visually recognize from the ground 11 side below the tip side of the roof body 6. Thus, since the beam 4 is difficult to visually recognize from the ground 11 side below the tip side of the roof body 6, the design property can be improved.

[0031] The extension plate portion 42 extends from the lower - end portion of the beam - side hollow portion 41 toward the center side in the front - rear direction in the roof body 6 (the side of the other beam 4 among the pair of beams 4) and is formed in a plate - like shape that extends in the left - right direction.

[0032] As shown in Figs. 5 and 6, a plurality of screw holes 421 into which screw members 101 used to fix the roof body 6 to the beam 4 are inserted are formed side - by - side in the left - right direction in the extension plate portion 42. The plurality of screw holes 421 are formed with a first gutter - shaped member attachment screw hole 421a, a hook - portion attachment screw hole 421b, and a second gutter - shaped member attachment screw hole 421c from the proximal - end side on the column 2 side toward the tip side of the beam 4, and then a plurality of one - side attachment screw holes 421d are formed side - by - side.

[0033] As shown in Fig. 5, the first gutter - shaped member attachment screw hole 421a is provided for fixing the base - end - side portion of the gutter - forming member 62 (described later) in the long - shaped member 61 and the extension plate portion 42 of the beam 4 with a screw member 105. The second gutter-shaped member mounting screw hole 421c is provided for fixing the tip-side portion of the gutter-forming member 62 (described later) in the long member 61 and the extending plate portion 42 of the beam 4 with a screw member 101. In the hook portion mounting screw hole 421b, when attaching the gutter-forming member 62 in the long member 61 to the beam 4, a hook portion 110 (see Fig. 5) for hooking and temporarily placing the gutter-forming member 62 of the long member 61 is provided for fixing with a screw member 106. As shown in Fig. 6, the single-side mounting screw hole 421d is provided for fixing the tip-side portion of the intermediate member 63 of the long member 61 and the extending plate portion 42 of the beam 4 with a screw member 101 when attaching the intermediate member 63 of the long member 61 to the beam 4.

[0034] As shown in Fig. 4, the connecting member 5 is formed in an L shape as a whole when viewed in the front-rear direction of the carport 1, and its cross-section is formed in a tubular shape. The connecting member 5 has a vertical tubular portion 51 extending in the vertical direction and a horizontal tubular portion 52 extending with a downward inclination such that the side of the vertical tubular portion 51 is downward and connected to the vertical tubular portion 51.

[0035] The connecting member 5 connects the column 2 and the beam 4. For the connecting member 5, the lower end portion (one side) of the vertical tubular portion 51 is inserted into the column-side hollow portion 21 of the column 2 from the upper end portion side of the column 2 and fixed to the column 2 only on one side surface on the roof body 6 side of the column 2 by four screw members 102 arranged in the vertical direction. For the connecting member 5, the tip portion (the other side) of the horizontal tubular portion 52 is inserted into the beam-side hollow portion 41 of the beam 4 and fixed by two screw members 103 from the upper side and also fixed by one screw member 104 from the lower side.

[0036] As shown in Fig. 4, the four screw members 102 arranged in the vertical direction for fixing the column 2 and the connecting member 5 fix the column 2 and the connecting member 5 at four locations on one side surface of the column 2 on the roof body 6 side. The screw member 102 exposed on one side surface of the column 2 on the roof body 6 side is covered by a column cover member 3 attached to the column 2 so as not to be visually recognized from the outside. Thereby, since the screw member 102 is not visually recognized from the outside, the design property can be improved.

[0037] A plurality of screw members 103 and 104 for fixing the beam 4 and the connecting member 5 fix the beam 4 and the connecting member 5 at two locations on the upper surface of the beam 4 and one location on the lower surface of the beam 4. Since the two screw members 103 on the upper surface side of the beam 4 are arranged to be exposed upward, they cannot be visually recognized from the lower side of the carport 1. Since the roof body 6 is arranged below the beam 4 for the one screw member 104 on the lower surface side of the beam 4, it cannot be visually recognized from the lower side of the carport 1.

[0038] As shown in FIG. 4, the roof body 6 has a hanging structure in which the roof body 6 is hung and arranged below a pair of beams 4, and is attached (connected) to the lower portions of the pair of beams 4. The roof body 6 is configured by a plurality of long members (long bars) 61 arranged side by side in the direction in which the beam 4 extends and fitted and connected to each other.

[0039] The plurality of long members 61 each extend in the front-rear direction of the carport 1 (a direction orthogonal to the direction in which the beam 4 extends) and have a predetermined thickness. The plurality of long members 61 are each formed of an extruded aluminum material and have a hollow structure having a hollow portion formed in a hollow shape in cross section. The upper surface 6a and the lower surface 6b of the roof body 6 are formed flat (planar). The roof body 6 is arranged in a downward slope with the support column 2 side downward, and the upper surface 6a and the lower surface 6b are formed in a downward slope with the support column 2 side downward. By connecting the plurality of long members 61 formed of an extruded aluminum material to form the roof body 6, the plurality of long members 61 can be used as the facing material of the roof body 6, and the strength of the roof body 6 can be ensured. Further, by configuring the plurality of long members 61 constituting the roof body 6 with members having hollow portions, the roof body 6 itself can be used as a strength member, and there is no need to separately provide a member for providing the strength of the roof body 6. Therefore, the number of parts of the members constituting the roof body 6 can be reduced.

[0040] As shown in FIG. 4, the plurality of elongated members 61 that constitute the roof body 6 include a gutter-forming member 62 disposed at the most proximal end on the strut 2 side, a tip-side member 64 disposed at the most distal end, and a plurality of intermediate members 63 disposed between the gutter-forming member 62 and the tip-side member 64. The plurality of elongated members 61 are each directly fixed to and connected to the beam 4 by screw members 101 and 105. In the present embodiment, an adhesive for preventing loosening is applied to the screw members 101 and 105. Note that it is not necessary to apply an adhesive for preventing loosening to the screw members 101 and 105.

[0041] The gutter-forming member 62 is arranged in parallel at the end on the strut 2 side in the direction in which the plurality of elongated members 61 are arranged in the roof body 6. The gutter-forming member 62 is an elongated member disposed at the end on the strut 2 side in the direction in which the plurality of elongated members 61 are arranged among the plurality of elongated members 61, and is configured as a roof-body side gutter structure. As shown in FIG. 5, the gutter-forming member 62 is formed of an elongated member with an upper side opening upward. In the present embodiment, the gutter-forming member 62 is formed of a solid material having no hollow portion and is formed in a U-shaped cross section with an upper side opening. Note that the gutter-forming member 62 is not limited to this, and it may be formed in a shape in which the upper side is opened by cutting out the upper surface of an aluminum material of a hollow structure having a hollow portion.

[0042] The gutter-forming member 62 constitutes a roof-body side gutter component 60 that receives and distributes the water that has flowed from the upper surface 6a of the roof body 6 to the proximal end side and reached the proximal end side at the most proximal end on the strut 2 side of the roof body 6. The roof-body side gutter component 60 is disposed at the downstream end of the water flowing on the upper surface 6a of the roof body 6. In the present embodiment, the roof-body side gutter component 60 is disposed at the end of the downward slope in the roof body 6 and at the end on the strut 2 side on the proximal end side of the roof body 6.

[0043] Since the upper side of the roof-body side gutter component 60 is open, when the roof-body side gutter component 60 is viewed from below the roof body 6, only the flat (planar) lower surface of the elongated member 61 can be seen, and the gutter can be configured without recognizing that there is a gutter on the upper surface 6a side of the roof body 6, thereby improving the design property.

[0044] The gutter forming member 62 has a gutter forming portion 621 formed on the support pillar 2 side at the base end of the roof body 6, a tip side upper outward extension piece 627 (fixed portion) formed on the tip side of the roof body 6, and a tip side lower outer piece 628 formed on the tip side of the roof body 6.

[0045] The gutter component 621 has a gutter component main body 622 that is approximately U-shaped and open at the top, a base end upper inward extending piece 623 that is arranged on the base end side of the roof body 6, a tip end upper inward extending piece 624 that is arranged on the tip end side of the roof body 6, a drain fin 625, and a base end upper wall 626.

[0046] The gutter forming body 622 receives water that flows toward the support pillars 2 on the upper surface 6a of the roof body 6 from an open portion at the top. An outlet opening 622a (drain outlet) is formed on the side of the gutter forming body 622.

[0047] 3 and 5, the outlet opening 622a is formed by penetrating the side surface of the gutter forming portion main body 622 laterally toward the support 2 side in a portion where one of the pair of support columns 2 on the near side in the front-rear direction is disposed. A side opening 71 (described later) of the L-shaped guide member 7 is connected to the outlet opening 622a.

[0048] As shown in Figures 3 and 5, the guide member 7 guides water that has flowed into and accumulated in the roof body side gutter component 60 to the support pillar side gutter component 20. When viewed from the front to back, the guide member 7 is formed in an L-shaped tube shape, and has a side opening 71 and a bottom opening 72. The side opening 71 on one side of the guide member 7 is connected to an outlet opening 622a formed on the side of the gutter component main body 622 (roof body side gutter component 60), and the bottom opening 72 on the other side is inserted between the support pillar 2 and the support pillar cover member 3 and opens into the interior of the support pillar side gutter component 20. Because the guide member 7 is positioned between the support pillar 2 and the support pillar cover member 3, the bottom opening 72 of the guide member 7 can be positioned on the support pillar 2 side without having to cut out the support pillar 2.

[0049] As shown in Fig. 5, the base-end side upper inner extension piece 623 protrudes inward from the inner surface on the upper side of the gutter component 621 at the base-end side of the gutter component 621. An attachment screw hole 623a into which the screw member 101 is screwed is formed in the base-end side upper inner extension piece 623.

[0050] The tip-end side upper inner extension piece 624 protrudes inward from the upper end of the gutter component 621 on the side opposite to the base-end in the width direction of the gutter component 621. A hook projection piece 624a protruding downward at the tip is formed at the tip of the tip-end side upper inner extension piece 624. When attaching the gutter forming member 62 to the beam 4, the gutter forming member 62 can be temporarily placed on the lower surface of the extension plate portion 42 of the beam 4 by hooking the hook projection piece 624a of the gutter forming member 62 on the rising plate 110d of the hook portion 110 fixed to the lower surface of the extension plate portion 42 of the beam 4. Further, with the hook projection piece 624a of the gutter forming member 62 hooked on the rising plate 110d of the hook portion 110 fixed to the lower surface of the extension plate portion 42 of the beam 4, the gutter forming member 62 can be arranged at the attachment position by rotating the gutter forming member 62 about the hook projection piece 624a. As shown in Fig. 5, the hook portion 110 has an attachment plate 110a attached to the lower surface of the extension plate portion 42 of the beam 4, a vertically extending plate 110b extending downward from the end on the tip side of the attachment plate 110a, a bottom plate 110c extending from the lower end portion of the vertically extending plate 110b to the tip side, and a rising plate 110d rising from the end on the tip side of the bottom plate 110c.

[0051] The hook projection piece 624a of the gutter forming member 62 is arranged above the hook portion 110 in a state where the gutter forming member 62 is fixed to the beam 4. Thereby, even when the screw members 105 and 101 for fixing the gutter forming member 62 come off in a state where the gutter forming member 62 is fixed to the beam 4, the hook projection piece 624a is hooked on the rising plate 110d of the hook portion 110, and the fall of the gutter forming member 62 can be suppressed.

[0052] As shown in FIG. 5, the water cutoff fin 625 projects downward from the lower end of the gutter component body 622 at the proximal end side of the roof body 6 in the gutter component body 622. The position of the lower end 625a of the water cutoff fin 625 is located below the upper end 31 of the support cover member 3 in the vertical direction.

[0053] The water cutoff fin 625 transmits the water derived from the water receiving channel portion 822 of the roof body side cover member 8 described later, and drops the water transmitted by the water receiving channel portion 822 of the roof body side cover member 8 below the roof body 6 so as not to flow onto the lower surface 6b of the roof body 6.

[0054] Further, since the position of the lower end 625a of the water cutoff fin 625 is located below the upper end 31 of the support cover member 3 in the vertical direction, the water cutoff fin 625 can cover the portion where the guiding member 7 is disposed above the upper end 31 of the support cover member 3. Thereby, since the guiding member 7 can be hidden from the outside, the design property can be improved.

[0055] The proximal end side upper wall 626 is formed to stand upright from the upper surface 6a of the roof body 6 at the proximal end side end of the roof body 6. The proximal end side upper wall 626 reduces the splash of water at the proximal end side end of the roof body 6.

[0056] The upper outer extension piece 627 on the tip side extends toward the tip side from the upper end portion on the tip side (left side) of the roof body 6 in the gutter component body 622. The upper outer extension piece 627 on the tip side is disposed at the upper end portion of the tip-side end portion of the gutter forming material 62, and constitutes a fixing portion fixed to the beam 4 by the screw member 101. The upper outer extension piece 627 on the tip side is formed above the hook engaging portion 628a in the intermediate member 63. A screw hole 627a is formed in the upper outer extension piece 627 on the tip side. When attaching the tip-side end portion of the gutter forming material 62 to the beam 4, the screw member 101 inserted from above the second gutter-shaped member attachment screw hole 421c of the extension plate portion 42 of the beam 4 is inserted into the screw hole 627a, and the screw member 101 is screwed into the nut member 601 disposed below the upper outer extension piece 627 on the tip side. The upper outer extension piece 627 on the tip side is fixed to the extension plate portion 42 of the beam 4 by the screw member 101 above the hook engaging portion 628a in the intermediate member 63.

[0057] On the end portion on the tip side (left side) of the roof body 6 in the upper outer extension piece 627 on the tip side, a side extension wall 627b and a downward extension wall 627c are formed. From the side surface on the base end side of the downward extension wall 627c, a tip-side locking piece 627d protrudes laterally on the base end side. At a position facing the tip-side locking piece 627d, a base-end-side locking piece 627e is formed which extends downward from below the upper outer extension piece 627 on the tip side and bends toward the tip-side locking piece 627d midway. Below the upper outer extension piece 627 on the tip side, the nut member 601 is locked by the tip-side locking piece 627d and the base-end-side locking piece 627e.

[0058] On the surface on the tip side (left side) of the downward extension wall 627c, a packing member 602 attached to the end portion on the base end side of the adjacent intermediate member 63 is pressed. The packing member 602 functions as a water stop portion (first water stop portion) disposed at the connecting portion between the gutter forming material 62 and the intermediate member 63. The packing member 602 is formed so as to extend along the direction in which the connecting portion between the gutter forming material 62 and the adjacent intermediate member 63 (long member 61) extends, that is, along the longitudinal direction of the long member 61.

[0059] The distal lower outer piece 628 extends from the lower end of the distal end side (left side) of the roof body 6 in the gutter component body 622 to the distal end side (left side). At the end of the distal end side (left side) of the distal lower outer piece 628, a hook engaging portion 628a (first engaging portion, first fitting portion) protruding upward is formed.

[0060] As shown in FIG. 5, the hook engaging portion 628a is formed at the lower end of the gutter forming member 62 attached to the beam 4 at the end of the distal end side (one end side in the width direction orthogonal to the longitudinal direction) of the gutter forming member 62. The hook engaging portion 628a rises upward from the distal lower outer piece 628 disposed at the lower end of the gutter forming member 62 at the end of the distal end side (one end side in the width direction orthogonal to the longitudinal direction) of the gutter forming member 62 attached to the beam 4, and is formed in a T shape extending in the width direction orthogonal to the longitudinal direction at the raised upper end portion. The hook engaging portion 628a includes a rising portion 628b, a first hook portion 628c (hook portion) extending from the upper end portion of the rising portion 628b to the distal end side, and a second hook portion 628d (hook portion) extending from the upper end portion of the rising portion 628b to the side opposite to the distal end (base end side, support side).

[0061] The first hook portion 628c of the hook engaging portion 628a of the intermediate member 63 can engage with a base end lower protruding piece 636 (second fitting portion) protruding from the side surface of the lower end of the base end side of the adjacent intermediate member 63 to the base end side. Further, the second hook portion 628d of the hook engaging portion 628a of the intermediate member 63 can engage with a return hook piece 635b (second engaging portion, second fitting portion) (described later) of a hook extending piece 635 formed at the end of the base end side (the end side on the gutter forming member 62 side in the width direction orthogonal to the longitudinal direction) of the adjacent intermediate member 63.

[0062] On the upper surface of the lower outer piece 628 at the tip side, water overflowing from the middle gutter component 610 (described later) (the first second water stop portion) in the intermediate member 63 of the adjacent long member 61 flows. The upper surface of the lower outer piece 628 at the tip side constitutes the lower gutter component 620 located in the lower stage in the vertical direction inside the roof body 6. The lower gutter component 620 has a gutter function for flowing water and functions as a water stop portion (the second second water stop portion). The lower gutter component 620 receives the water that has passed through the packing member 602 and has been received by the middle gutter component 610 and has overflowed from the middle gutter component 610 (the first second water stop portion), and distributes the received water to both end sides in the front-rear direction. That is, the roof body 6 is provided with a two-stage gutter structure at the connecting portion of the adjacent long members 61, and includes a middle gutter component 610 that is arranged on the upper stage side and receives water on the upper stage side, and a lower gutter component 620 that is arranged on the lower stage side and receives the water that has overflowed from the middle gutter component 610 on the lower stage side. The middle gutter component 610 and the lower gutter component 620 extend along the direction in which the connecting portion of the adjacent long members 61 extends, that is, along the longitudinal direction of the long member 61.

[0063] The gutter forming member 62 is fixed to the beam 4 at the base end side by screwing the screw member 105 that has been moved from the upper side and passed through the first gutter-shaped member mounting screw hole 421a of the extended plate portion 42 of the beam 4 into the mounting screw hole 623a of the inner extended piece 623 at the upper part of the base end side. Also, in the gutter forming member 62, as shown in FIG. 5, the nut member 601 is attached inside the gutter forming member 62 at the tip end side of the gutter forming member 62. The gutter forming member 62 is fixed to the beam 4 at the tip side by screwing the screw member 101 that has been inserted through the one-sided mounting screw hole 421d of the extended plate portion 42 of the beam 4 and the screw hole 627a of the outer extended piece 627 at the upper part of the tip side into the nut member 601 by the screw member 101 that has been moved from the upper side.

[0064] The intermediate members 63 are arranged in a plurality and placed between the gutter-shaped forming members 62 and the tip-side members 64. As shown in FIG. 6, the intermediate member 63 includes a first intermediate hollow portion 631 disposed on the intermediate member 63 side, a second intermediate hollow portion 632 disposed on the tip side of the first intermediate hollow portion 631, a packing mounting recess 633 formed on the side surface of the upper end portion on the base end side in the first intermediate hollow portion 631, a middle gutter portion 634 as an L-shaped second water stop portion extending from approximately the center in the vertical direction on the surface of the first intermediate hollow portion 631 on the intermediate member 63 side toward the intermediate member 63 side, an L-shaped hook extension piece 635 extending downward from the lower end portion of the end portion on the base end side of the middle gutter portion 634, a base end side lower protruding piece 636 (second fitting portion, hooking protruding portion) protruding from the side surface of the lower end portion on the intermediate member 63 side in the first intermediate hollow portion 631 toward the base end side, a tip side upper outer extension piece 637 (fixing portion), and a tip side lower outer piece 638.

[0065] As shown in FIG. 5, an opening 639 that opens downward is formed below the end portion on the base end side of the middle gutter portion 634. The opening 639 is formed by an end side 631a extending in the vertical direction disposed on the base end side of the first intermediate hollow portion 631 in the middle gutter portion 634 and the L-shaped hook extension piece 635. Opposing protruding portions 639a (second fitting portions) that protrude toward the inside of the opening 639 and oppose each other are formed on the opening edge of the opening 639. In the present embodiment, the opposing protruding portions 639a are constituted by the base end side lower protruding piece 636 and a return hook piece 635b (described later) of the L-shaped hook extension piece 635, and protrude and extend toward the inside of the opening 639 so as to approach each other.

[0066] In the gutter forming member 62 and the intermediate member 63 configured as described above, when the adjacent gutter forming member 62 and the intermediate member 63 are in a fitted state, the first hooking portion 628c of the hooking engagement portion 628a of the gutter forming member 62 engages (fits) with the base end side lower protruding piece 636 of the adjacent intermediate member 63, and the second hooking portion 628d of the hooking engagement portion 628a of the gutter forming member 62 engages (fits) with the return hooking piece 635b (described later) of the hooking extension piece 635 of the adjacent intermediate member 63. Thus, the adjacent gutter forming member 62 and the intermediate member 63 are fitted to each other. In the present embodiment, in a state where the adjacent gutter forming member 62 and the intermediate member 63 are connected, the hooking engagement portion 628a (the first hooking portion 628c and the second hooking portion 628d) of the gutter forming member 62 is disposed inside the opening 639 of the adjacent intermediate member 63 and is hooked and fitted to the opposing protruding portion 639a (the base end side lower protruding piece 636, the return hooking piece 635b of the L-shaped hooking extension piece 635) so as to restrict movement in the vertical direction.

[0067] The packing mounting recess 633 is disposed to face the downward extending wall 627c of the gutter forming member 62 adjacent to the base end side. The packing mounting recess 633 extends along the direction in which the connecting portion of the adjacent long member 61 extends, that is, along the longitudinal direction of the long member 61. A packing member 602 is attached to the packing mounting recess 633. The packing member 602 presses the downward extending wall 627c of the gutter forming member 62 adjacent to the base end side in a state of being attached to the packing mounting recess 633. The packing member 602 is disposed at the connecting portion between the gutter forming member 62 and the intermediate member 63 and functions as a water stop portion (the first water stop portion).

[0068] The middle gutter portion 634 has a bottom wall portion 634a and a standing piece 634b. The middle gutter portion 634 constitutes a middle gutter component 610 located in the middle in the vertical direction inside the roof body 6. The middle gutter component 610 has a gutter function for flowing water and functions as a water stop portion (the second water stop portion of the first). The middle gutter component 610 receives the water that has passed through the packing member 602 that could not be stopped by the packing member 602 and distributes the received water to both end sides in the front-rear direction.

[0069] The L-shaped hook extension piece 635 has a downward extension piece 635a and a return hook piece 635b (a second fitting part, a hook protrusion part) extending from the lower end part of the downward extension piece 635a back toward the first intermediate hollow part 631 side. The return hook piece 635b can be engaged with a hook engagement part 628a (a first fitting part) formed at the end part on the tip side of the adjacent gutter structure forming member 62. The return hook piece 635b can rotate around the hook engagement part 628a in a state of being engaged with the hook engagement part 628a.

[0070] When attaching the adjacent intermediate member 63 next to the gutter structure forming member 62 connected to the beam 4, the intermediate member 63 can be temporarily placed below the beam 4 by hooking the hook extension piece 635 of the intermediate member 63 on the hook engagement part 628a of the gutter structure forming member 62 attached to the beam 4. Also, with the hook extension piece 635 of the intermediate member 63 hooked on the hook engagement part 628a of the gutter structure forming member 62, the intermediate member 63 can be arranged at the attachment position by rotating the intermediate member 63 around the tip of the hook extension piece 635. In a state where the intermediate member 63 is arranged at the attachment position, the intermediate member 63 is attached on the tip side of the beam 4 in the gutter structure forming member 62 with the hook extension piece 635 of the intermediate member 63 fitted to the hook engagement part 628a of the gutter structure forming member 62.

[0071] Regarding the upper outer extension piece 637 and the lower outer piece 638 on the tip side of the intermediate member 63, for points not described, they are the same as the structures of the upper outer extension piece 627 and the lower outer piece 628 on the tip side of the gutter structure forming member 62. Therefore, regarding the structures of the upper outer extension piece 637 and the lower outer piece 638 on the tip side of the intermediate member 63, corresponding reference numerals to the structure of the gutter structure forming member 62 are given in FIG. 6, and the description thereof is omitted.

[0072] In the intermediate member 63, as shown in FIG. 6, the nut member 601 is attached inside the intermediate member 63 at the tip side in the intermediate member 63 (the end side opposite to the return hook piece 635b (second engaging portion) in the width direction orthogonal to the longitudinal direction). At the tip side of the intermediate member 63, a screw member 101 that is moved from the upper side is inserted through the one-side attachment screw hole 421d of the extension plate portion 42 of the beam 4 and the screw hole 637a of the tip-side upper outer extension piece 637. By screwing the screw member 101 into the nut member 601, the intermediate member 63 is fixed to the beam 4.

[0073] Also, among the plurality of intermediate members 63 arranged continuously, the configuration of the intermediate member 63 arranged adjacent to the tip side of the intermediate member 63 connected to the beam 4 is the same as the configuration of the intermediate member 63 arranged adjacent to the tip side of the gutter forming member 62 connected to the beam 4. Therefore, the description of the configuration of the intermediate member 63 arranged adjacent to the intermediate member 63 is omitted.

[0074] When attaching an adjacent intermediate member 63 next to the intermediate member 63 connected to the beam 4, similar to the case of attaching an intermediate member 63 next to the gutter forming member 62, by hooking the hooking extension piece 635 (second engaging portion) of the intermediate member 63 on the hooking engaging portion 638a (first engaging portion) of the intermediate member 63 attached to the beam 4, the intermediate member 63 can be temporarily placed below the beam 4. Further, with the hooking extension piece 635 of the intermediate member 63 hooked on the hooking engaging portion 638a of the intermediate member 63, by rotating the intermediate member 63 around the tip of the hooking extension piece 635, the intermediate member 63 can be arranged at the attachment position. In a state where the adjacent intermediate member 63 is arranged at the attachment position, on the tip side of the beam 4 in the already attached intermediate member 63, with the hooking extension piece 635 of the adjacent intermediate member 63 fitted to the hooking engaging portion 638a of the already attached intermediate member 63, the adjacent intermediate member 63 is attached.

[0075] As shown in Fig. 4, the tip-side member 64 is disposed on the tip side of a plurality of intermediate members 63 connected to the beam 4. The tip-side member 64 has one hollow portion 641. Also, since the shape of the proximal end side of the tip-side member 64 on the side of the support column 2 is the same as the shape of the intermediate member 63 on the side of the support column 2, the description thereof is omitted by referring to the description of the intermediate member 63. Further, even when attaching an adjacent tip-side member 64 next to the intermediate member 63 connected to the beam 4, it is the same as the case of attaching the intermediate member 63 next to the gutter-forming member 62. In a state where the tip-side member 64 is disposed at the attachment position, the tip-side member 64 is attached in a state where a hook extension piece (not shown) of the tip-side member 64 is fitted to the hook engagement portion 638a of the intermediate member 63 on the tip side of the beam 4 in the intermediate member 63 adjacent to the tip-side member 64.

[0076] Also, among the plurality of long members 61 constituting the roof body 6, in the tip-side member 64 disposed at the most tip side, as shown in Figs. 8 and 9, both end portions in the longitudinal direction of the tip-side member 64 are fixed to the upper surface cover portions 81 of a pair of roof-body side cover members 8 (described later) by screw members 107 as shown in Figs. 8 and 9. As shown in Fig. 1, the pair of roof-body side cover members 8 extend in a direction (the direction in which the beam 4 extends) orthogonal (intersecting) to the longitudinal direction of the tip-side member 64 at both end portions in the longitudinal direction of the tip-side member 64 (both end portions in the front-rear direction of the roof body 6).

[0077] In the roof structure configured as described above, as shown in Fig. 4, the plurality of long members 61 in the roof body 6 are arranged and connected in the order of the gutter-forming member 62, the plurality of intermediate members 63, and the tip-side member 64 from the proximal end side to the tip side of the beam 4. The gutter-forming member 62, the plurality of intermediate members 63, and the tip-side member 64 are respectively fitted and connected at the proximal end side of the beam 4, and are fixed to the beam 4 by screw members 101 at the tip side of the beam 4.

[0078] The roof body tip cover member 65 is attached to the tip of the tip side profile member 64 at the very tip of the roof body 6. The roof body tip cover member 65 extends in the front-rear direction of the roof body 6. As shown in FIG. 4, the roof body tip cover member 65 has a fin 651 that protrudes downward at the lower end portion on the tip side.

[0079] As shown in FIG. 1, a pair of roof body side cover members 8 are arranged to extend in a direction orthogonal (intersecting) to the longitudinal direction of the long profile member 61 at both ends of the long profile member 61. The pair of roof body side cover members 8 are arranged to cover the sides of the long profile member 61 at both ends in the front-rear direction of the roof body 6. Each of the pair of roof body side cover members 8 has a downward slope with the support column 2 side lower and extends along the inclination direction of the roof body 6. As shown in FIG. 8, the roof body side cover member 8 has an upper surface cover portion 81 and a side surface cover portion 82.

[0080] The upper surface cover portion 81 is formed to have a width in the left-right direction and is formed in a plate shape that extends in the left-right direction along the inclination direction of the roof body 6. The upper surface cover portion 81 is arranged to be locked to the upper surface 6a of the roof body 6.

[0081] The side surface cover portion 82 is connected to the outside of the side portion of the end portion of the upper surface cover portion 81, is formed to have a width in the up-down direction, and is formed in a plate shape that extends in the left-right direction along the inclination direction of the roof body 6. The side surface cover portion 82 is arranged to cover the side portions of the end portions in the front-rear direction of the roof body 6.

[0082] The side surface cover portion 82 has an upper protruding portion 821 that protrudes upward, a water receiving flow path portion 822 (third water stop portion) that is formed on the lower side and extends inward from the inner surface, a water draining protruding portion (water draining fin) 823 that protrudes downward from the lower portion of the water receiving flow path portion 822, and two protruding portions 824 that protrude inward from the inner surface on the upper side of the water receiving flow path portion 822.

[0083] The water receiving channel portion 822 receives the water that is led out from the middle gutter component portion 610 and the lower gutter component portion 620 and flows to the front and rear ends of the roof body 6. The water receiving channel portion 822 constitutes a channel through which water flows from the distal end side to the proximal end side of the roof body 6 and functions as a water stop portion for stopping water. Since the water received by the water receiving channel portion 822 is configured to have a downward slope in which the side cover portion 82 slopes toward the proximal end side, it flows toward the proximal end side. The water that is flowed to the proximal end side of the roof body 6 by the water receiving channel portion 822 drops below the roof body 6 at the proximal end side.

[0084] Here, at the proximal end side of the side cover portion 82, a drain fin 625 that extends downward from the lower end portion of the gutter forming member 62 that is formed to extend in a direction orthogonal to the side cover portion 82 is disposed. Therefore, a part of the water that flows on the upper surface of the water receiving channel portion 822 of the side cover portion 82 is transmitted to the drain fin 625. From the drain fin 625, the water transmitted from the water receiving channel portion 822 of the side cover portion 82 drops below the roof body 6 at the proximal end portion side of the roof body 6.

[0085] In the carport 1 configured as described above, since the lower surface 6b is planar when the roof body 6 is viewed from below, the design property can be improved. Further, since the roof body 6 is configured by arranging a plurality of long members 61, the roof body can be configured without using a framed frame (frame body). Thereby, the thickness of the roof body 6 can be formed thinner than in the case of using a frame (frame body), and the lower surface 6b of the roof body 6 can be made into a flat shape without unevenness.

[0086] In addition, a plurality of long members 61 are arranged side by side in the direction in which the beam 4 extends. Therefore, among the plurality of long members 61, the longitudinal direction of the long member 61 can be arranged to extend in a direction intersecting the direction in which the beam 4 extends, so that the plurality of long members 61 can be directly fixed to the beam 4. As a result, when connecting the plurality of long members 61 to the beam 4, it is not necessary to connect the plurality of long members 61 to the beam 4 via a support member or the like. Therefore, since it is not necessary to connect the beam 4 and the plurality of long members 61 using a support member or the like, the number of parts can be reduced and the workability can be improved. In addition, since it is not necessary to arrange a support member or the like between the beam 4 and the plurality of long members 61, the height dimensions of the beam 4 and the roof body 6 can be reduced.

[0087] In addition, since the roof body 6 is configured by arranging a plurality of long members 61 side by side, the manufacturing cost can be reduced compared to a roof body configured with a double structure of the roof body and a ceiling material having a flat lower surface. In addition, since the roof body 6 is suspended from the beam 4 below the beam 4, the beam 4 located above the roof body 6 is shielded by the roof body 6 when the carport 1 is viewed from below, so that it is difficult to be visually recognized. Thereby, the design property of the carport 1 can be improved.

[0088] Next, a construction method of the carport will be described with reference to FIGS. 10 to 13. First, as shown in FIG. 10, the support column 2 is installed and the beam 4 is connected to the support column 2. Specifically, after fixing the lower end portion of the support column 2 to the ground 11, the lower end portion of the L-shaped connecting member 5 is inserted into the upper end portion of the hollow portion 21 on the support column side of the support column 2. The lower end portion of the connecting member 5 and the upper end portion of the support column 2 are fixed by four screw members 102 arranged in the vertical direction on the side surface of the upper end portion of the support column 2 on the roof body 6 side.

[0089] Subsequently, as shown in FIG. 10, the support column cover member 3 is attached to the side surface of the support column 2 on the roof body 6 side so as to cover the four screw members 102. As a result, the four screw members 102 that fix the connecting member 5 and the upper end portion of the support column 2 are not visually recognized from the outside. Therefore, the design property can be improved.

[0090] Further, the column cover member 3 is arranged to cover the four screw members 102 that are fixed only to one side surface of the connecting member 5 on only one side surface of the column 2 (see FIG. 4). Therefore, the number of components can be reduced and the cost can be reduced as compared with providing cover members on both side surfaces of the column 2. In addition, since the column cover member 3 only needs to be attached to one side surface of the column 2, the workability of attaching the column cover member 3 is improved. Further, it is possible to suppress an increase in the dimension of the width of the column 2 as compared with providing cover members on both side surfaces of the column 2.

[0091] Further, the column cover member 3 is constituted by a single cover member extending in the vertical direction. Therefore, the number of components can be reduced and the cost can be reduced as compared with being constituted by a plurality of cover members. In addition, since the column cover member 3 is constituted by a single cover member, the attachment work is easy and the workability is improved. Further, since the column cover member 3 is constituted by a single cover member, the designability can be improved as compared with the cover members being arranged separately due to being constituted by a plurality of cover members.

[0092] Water flows between the side surface of the column 2 and the column cover member 3. The column side gutter component 20 is constituted by the side surface of the column 2 and the column cover member 3. Since the column side gutter component 20 is not visible from the outside, the designability can be improved. Further, the column cap 201 is fixed to the upper end portion of the connecting member 5 by screwing so as to cover the opening at the upper end portion of the column 2.

[0093] Next, the lateral end portion on the other end side of the connecting member 5 is inserted into the proximal end side of the beam side hollow portion 41 of the beam 4. Then, the connecting member 5 and the beam 4 are fixed by three screw members 103, 103, 104. The two screw members 103 fix the beam 4 and the connecting member 5 from the upper surface side of the beam 4, and the one screw member 104 fixes the beam 4 and the connecting member 5 from the lower surface side of the beam 4. In addition, an end cap 43 is attached to the end portion on the distal end side of the beam 4. Further, the guiding member 7 is attached so that the lower end opening 72 is arranged between the column 2 and the column cover member 3.

[0094] Subsequently, as shown in FIG. 10, a roof body 6 is attached to the lower part of the beam 4. Specifically, a plurality of long members 61 are attached to the lower surface of the extending plate portion 42 of the beam 4 one by one in order from the end side on the proximal end side (strut 2 side) of the beam 4 to the beam 4.

[0095] Specifically, first, as shown in FIG. 10, an operator attaches a gutter structure forming member 62 to the lower surface of the extending plate portion 42 of the beam 4 at the most proximal end side (strut 2 side) of the roof body 6. As shown in FIG. 12, when constructing the gutter structure forming member 62 on the beam 4, the operator hangs the hook protruding piece 624a of the gutter structure forming member 62 on the hook portion 110 fixed to the lower surface of the extending plate portion 42 of the beam 4, thereby temporarily placing the gutter structure forming member 62 on the lower surface of the extending plate portion 42 of the beam 4. As a result, since the operator can temporarily release the hand from the gutter structure forming member 62, even a single operator can perform the work, and the workability when attaching the gutter structure forming member 62 to the beam 4 can be improved.

[0096] Thereafter, with the hook protruding piece 624a of the gutter structure forming member 62 hooked on the hook portion 110 fixed to the lower surface of the extending plate portion 42 of the beam 4, the operator rotates the gutter structure forming member 62 around the hook protruding piece 624a to arrange the gutter structure forming member 62 at the attachment position. Therefore, since the gutter structure forming member 62 can be easily moved from the temporarily placed state to the attachment position, the workability when attaching the gutter structure forming member 62 to the beam 4 can be improved. By simply hooking and rotating the hook protruding piece 624a on the hook portion 110, the long member 61 can be arranged at the attachment position to the beam 4. Thereby, the constructability of constructing the roof body 6 can be improved.

[0097] Next, the operator fixes the gutter forming member 62 to the extending plate portion 42 of the beam 4 with screw members 101 and 105. Specifically, at the proximal end side, the operator moves the screw member 105 from the upper side, inserts the screw member 105 that has passed through the first gutter-shaped member mounting screw hole 421a of the extending plate portion 42 of the beam 4 into the mounting screw hole 623a of the inner extending piece 623 at the upper part of the proximal end side, and screws the proximal end side of the gutter forming member 62 to the beam 4. Also, at the distal end side, the operator moves the screw member 101 from the upper side, inserts the screw member 101 that has passed through the second gutter-shaped member mounting screw hole 421c of the extending plate portion 42 of the beam 4 and the screw hole 627a of the outer extending piece 627 at the upper part of the distal end side into the nut member 601, and screws the distal end side of the gutter forming member 62 to the beam 4. The gutter forming member 62 constitutes the roof body side gutter component 60. Since the roof body side gutter component 60 is not visible from below the roof body 6, the design property can be improved.

[0098] Subsequently, as shown in FIG. 11, the operator attaches the intermediate member 63 to the lower surface of the extending plate portion 42 of the beam 4 adjacent to the distal end side of the gutter forming member 62 attached to the most proximal end side. As shown in FIG. 13, when constructing the intermediate member 63 on the beam 4 adjacent to the distal end side of the gutter forming member 62, the operator hooks the return hooking piece 635b of the hooking extending piece 635 of the intermediate member 63 on the hooking engaging portion 628a of the gutter forming member 62 attached to the beam 4, and temporarily places the intermediate member 63 below the beam 4. Thereby, since the operator can temporarily release the hand from the intermediate member 63, even a single operator can perform the work, and the workability when attaching the gutter forming member 62 to the beam 4 can be improved.

[0099] After that, with the engaging extension piece 635 of the intermediate member 63 hooked on the hooking engaging part 628a of the gutter forming member 62, the intermediate member 63 is rotated about the return hooking piece 635b (and the hooking engaging part 628a) of the engaging extension piece 635 to place the intermediate member 63 at the mounting position (placement step). Thereby, since the intermediate member 63 can be easily moved from the temporarily placed state to the mounting position, the workability when attaching the intermediate member 63 to the beam 4 can be improved. Further, just by hooking and rotating the return hooking piece 635b on the hooking engaging part 628a, the long member 61 can be placed at the mounting position on the beam 4. Thereby, the workability of constructing the roof body 6 can be improved.

[0100] Next, the operator fixes the intermediate member 63 to the extending plate part 42 of the beam 4 with the screw member 101. Specifically, at the tip side, the screw member 101 is moved from above, and the screw member 101 passed through the one-sided attachment screw hole 421d of the extending plate part 42 of the beam 4 and the screw hole 637a of the tip-side upper outer extending piece 637 is screwed with the nut member 601 to fix the tip side of the gutter forming member 62 to the beam 4 (fixing step).

[0101] Here, the base end side of the intermediate member 63 is engaged in a state where the engaging extension piece 635 of the intermediate member 63 is hooked on the hooking engaging part 628a of the gutter forming member 62 without being fixed with a screw member. Therefore, if only the tip side (one side) of the intermediate member 63 is fixed with the screw member 101, the intermediate member 63 can be fixed to the beam 4. Further, the intermediate member 63 can be fixed to the beam 4 just by moving the screw member 101 from above. Thereby, the workability when attaching the gutter forming member 62 to the beam 4 can be improved.

[0102] Subsequently, as shown in FIG. 11, adjacent to the tip side of the intermediate member 63 attached to the beam 4, a plurality of intermediate members 63 are successively and continuously attached in order from the base end side to the tip side of the roof body 6. Specifically, the plurality of intermediate members 63 are temporarily placed, rotated, and fixed by the screw member 101 in order from the base end side of the roof body 6, and this is repeated. Since these methods are the same as the case of attaching the intermediate member 63 adjacent to the gutter forming member 62 described above, the description is omitted. After attaching the plurality of intermediate members 63 to the beam 4, a tip side member 64 is attached to the tip side of the roof body 6. Then, a roof body tip cover member 65 is attached to the tip portion of the tip side member 64.

[0103] In this way, after temporarily placing the long member 61, the long member 61 can be rotated and fixed to the beam 4 by the screw member 101, so that an operator can easily assemble the carport 1 alone. Further, when attaching the long member 61 (gutter forming member 62, intermediate member 63, tip side member 64) to the beam 4, the long member 61 can be attached one by one in order from the base end side (the support column 2 side), and the long member 61 can be fixed to the beam 4 only by moving the screw member 101 from above, so that the attachment work can be easily performed. Thereby, the workability when constructing the carport 1 can be improved.

[0104] Further, the intermediate member 63 can be attached to the beam 4 by fixing only one side in the width direction of the intermediate member 63. Therefore, the workability of constructing the roof body 6 can be improved. In addition, since the plurality of long members 61 are attached to the beam 4 in order from the support column 2 side, the long members 61 can be constructed in order from the support column 2 side, so that the alignment of the long members 61 is easy. Further, when arranging the long members 61, the long members 61 can be constructed in order on the side away from the support column 2, so that the support column 2 is less likely to get in the way. Thereby, the workability of constructing the roof body 6 can be improved. In addition, the construction method of the carport 1 of the present embodiment includes a step of attaching a plurality of long members 61 to the beam 4 in order from the column 2 side. Therefore, since the long members 61 can be constructed in order from the column 2 side, it is easy to align the long members 61. Further, when arranging the long members 61, the column 2 is less likely to get in the way. Thereby, the workability of constructing the roof body 6 can be improved.

[0105] Next, the flow of rainwater in the carport 1 will be described. The rainwater pouring down on the upper surface 6a of the roof body 6 flows along the inclination of the upper surface 6a of the roof body 6 toward the column 2 side on the proximal end side as shown in FIG. 1. The water flowing to the column 2 side flows into the roof body side gutter component 60 and then flows into the column side gutter component 20 between the column 2 and the column cover member 3 through the guiding member 7 connected to the discharge opening 622a of the roof body side gutter component 60. The water flowing into the column side gutter component 20 drops to the ground 11 side through the column side gutter component 20, is received by the drain receiving lid member 24, and is discharged to the outside of the column 2 through the discharge opening 24a disposed near the ground 11.

[0106] Here, as shown in FIGS. 5 and 6, a packing member 602 is disposed at the connection portion between the long members 61. Therefore, the water flowing on the upper surface 6a of the roof body 6 can be stopped by the packing member 602 at the connection portion between the long members 61. Thereby, it is possible to suppress the water flowing on the upper surface 6a of the roof body 6 from falling from the lower surface 6b of the roof body 6 by the packing member 602.

[0107] Even when water passes through the packing member 602, inside the roof body 6, the middle gutter component 610 and the lower gutter component 620 are continuously provided in two steps with a step, forming a double water stop portion. The water that has passed through the packing member 602 (the first water stop portion) flows into the lower gutter component 620 (the first second water stop portion). The water that has overflowed from the middle gutter component 610 (the first second water stop portion) flows into the lower gutter component 620 (the second second water stop portion). Due to the two-step gutter structure of the middle gutter component 610 and the lower gutter component 620, water can be drained along the direction in which the connecting portion of the adjacent long members 61 extends, that is, along the longitudinal direction of the long members 61, enabling water stoppage. Thus, it is possible to further suppress water from falling from the lower surface 6b of the roof body 6.

[0108] The water introduced into the middle gutter component 610 (the first second water stop portion) and the lower gutter component 620 (the second second water stop portion) flows toward the front and rear ends of the roof body 6. The water that has flowed toward the front and rear ends is introduced into the roof body side cover member 8.

[0109] The water introduced into the roof body side cover member 8 is received by a water receiving channel portion 822 (see FIG. 8) (the third water stop portion) formed at the lower end of the roof body side cover member 8 and flows along the inclination of the roof body 6 toward the column 2 on the proximal end side. The water that has flowed toward the column 2 side in the water receiving channel portion 822 of the roof body side cover member 8 flows to the proximal end side of the roof body 6 on the column 2 side and falls downward from the end portion on the proximal end side of the roof body 6 on the column 2 side. Therefore, by flowing water in a direction intersecting the connecting portion of the adjacent long members 61 through the water receiving channel portion 822, water can be drained to the proximal end side of the roof body 6, suppressing water from falling from a portion other than the end portion of the lower surface 6b of the roof body 6.

[0110] At the same time as it falls downward from the end on the base end side on the strut 2 side of the roof body 6, a part of the water that has flowed to the strut 2 side in the water receiving channel portion 822 is transferred from the end on the base end side on the strut 2 side of the roof body 6 to the drainage fin 625 (see FIGS. 5 and 8) that protrudes downward at the lower end on the base end side of the gutter forming member 62 of the roof body 6, and at the end on the base end side of the gutter forming member 62 of the roof body 6, it falls downward through the drainage fin 625. By allowing water to fall from the drainage fin 625, it is possible to prevent water from flowing around to the lower surface 6b side of the roof body 6. As a result, it is possible to prevent water from falling from a portion other than the end of the lower surface 6b of the roof body 6.

[0111] Next, the fall prevention structure of the roof body 6 of the carport 1 will be described. FIG. 14 is a diagram for explaining the fall prevention structure of the intermediate member 63 in the roof body 6. FIG. 15 is a diagram for explaining the fall prevention structure of the gutter forming member 62 in the roof body 6.

[0112] First, the fall prevention structure of the intermediate member 63 in the roof body 6 will be described. In the present invention, as shown in FIG. 6, in a state where adjacent intermediate members 63 are connected, at the end on the tip side of the intermediate member 63, the hooking engagement portion 638a (the first hooking portion 638c and the second hooking portion 638d) of the intermediate member 63 is disposed inside the opening 639 of the adjacent intermediate member 63 and is hooked and fitted to the opposing protruding portion 639a (the base end side lower protruding piece 636, the return hooking piece 635b of the L-shaped hooking extension piece 635) so as to restrict movement in the vertical direction.

[0113] Therefore, at the end on the tip side of the intermediate member 63 on the side fixed by the screw member 101, as shown in FIG. 14, even if the screw member 101 that fixes the tip side upper outer extension piece 637 of the intermediate member 63 to the extension plate portion 42 of the beam 4 comes off, as shown in FIG. 14(a), at the lower part of the connecting portion below the screw member 101 in the adjacent intermediate member 63, the hook engaging portion 638a of the intermediate member 63 is hooked and fitted to the opposing protruding portion 639a of the adjacent intermediate member 63, and at the upper part, the intermediate members 63 are in contact with each other and interfere with each other. Therefore, the fitting between the adjacent intermediate members 63 has a structure that is difficult to come off.

[0114] Also, in the present embodiment, in the portion of FIG. 14(a), even if the screw member 101 that fixes the intermediate member 63 comes off, the intermediate member 63 from which the screw member 101 has come off is fitted and connected to the adjacent intermediate members 63 on both sides thereof. Thereby, the intermediate member 63 from which the screw member 101 has come off is restricted from moving downward by the fitting of the adjacent intermediate members 63 on both sides. Therefore, even if the screw member 101 comes off, the roof body 6 is only slightly deflected downward at the location where the screw member 101 has come off, and the fall of the roof body 6 is suppressed.

[0115] Even if the fitting on one side of the adjacent intermediate member 63 breaks in the intermediate member 63 from which the screw member 101 has come off, as shown in FIG. 14(b), the intermediate member 63 from which the screw member 101 has come off is in a state where the hook engaging portion 638a of the intermediate member 63 is hooked on the return hook piece 635b of the hook extension piece 635 of the adjacent intermediate member 63, and the intermediate member 63 only rotates around the return hook piece 635b of the hook extension piece 635 and does not hang down and fall on the adjacent intermediate member 63. Therefore, since the intermediate member 63 does not fall, the fall of the roof body 6 can be suppressed.

[0116] Next, the fall prevention structure of the gutter forming member 62 disposed at the end on the strut 2 side in the roof body 6 will be described. When the gutter forming member 62 is connected to the beam 4, as shown in FIG. 15, a hook portion 110 is disposed below the hooking projection piece 624a of the gutter forming member 62. Therefore, among the plurality of long members 61 constituting the roof body 6, in the gutter forming member 62 disposed closest to the strut 2 side, as shown in FIG. 15, even if the screw members 101 and 105 at both ends in the direction in which the beam 4 extends are detached, the inner extending piece 624 at the upper part of the tip side of the gutter forming member 62 is hooked on the rising plate 110d of the hook portion 110, and the gutter forming member 62 is suppressed from falling. Thereby, it is possible to prevent the roof body 6 from falling.

[0117] Next, the fall prevention structure of the tip side member 64 disposed at the tip end portion in the roof body 6 will be described. Among the plurality of long members 61 constituting the roof body 6, in the tip side member 64 disposed closest to the tip side (see FIG. 4), as shown in FIGS. 8 and 9, both ends in the longitudinal direction of the tip side member 64 are fixed to the upper surface cover portions 81 of the pair of roof body side cover members 8 by screw members 107. Therefore, even if the screw member 101 (see FIG. 4) that fixes the tip side of the tip side member 64 comes off, the tip side member 64 is fixed to the roof body side cover member 8 by the screw member 107 at both ends in the longitudinal direction, so that it is possible to prevent the tip side member 64 from falling.

[0118] According to the carport 1 of the present embodiment described above, the following effects can be obtained. The carport 1 of the present embodiment includes a strut 2, a beam 4 connected to the strut 2, and a roof body 6 connected to the beam 4, the roof body 6 having a plurality of long members 61 arranged side by side in a predetermined direction and having a lower surface 6b formed in a planar shape.

[0119] Therefore, since the lower surface 6b is planar when the roof body 6 is viewed from below, the design property can be improved. Further, since the roof body 6 is configured by arranging a plurality of long members 61, the roof body can be configured without using a framed frame (frame body). As a result, the thickness of the roof body 6 can be made thinner than when using a frame (frame body), and the lower surface 6b of the roof body 6 can be made into a flat shape without unevenness. Also, since the roof body 6 is configured by arranging a plurality of long members 61, the manufacturing cost can be reduced compared to a roof body configured with a double structure of the roof body and a ceiling member having a flat lower surface.

[0120] In the carport 1 of the present embodiment, the plurality of long members 61 are arranged side by side in the direction in which the beam 4 extends. Therefore, among the plurality of long members 61, the long direction of the long member 61 can be arranged to extend in a direction intersecting the direction in which the beam 4 extends, so that the plurality of long members 61 can be directly fixed to the beam 4. As a result, when connecting the plurality of long members 61 to the beam 4, it is not necessary to connect the plurality of long members 61 to the beam 4 via a support member or the like. Therefore, since it is not necessary to connect the beam 4 and the plurality of long members 61 using a support member or the like, the number of parts can be reduced and the workability can be improved. Also, since it is not necessary to arrange a support member or the like between the beam 4 and the plurality of long members 61, the height dimensions of the beam 4 and the roof body 6 can be reduced.

[0121] In the carport 1 of the present embodiment, the roof body 6 is suspended and arranged from the beam 4 below the beam 4. Therefore, the beam 4 located above the roof body 6 is difficult to be visually recognized because it is shielded by the roof body 6 when the carport 1 is viewed from below. As a result, the design property of the carport 1 can be improved.

[0122] In addition, in the present embodiment, the gutter forming member 62 has a hooking engagement portion 628a, and the intermediate member 63 attached to the beam 4 adjacent to the gutter forming member 62 has a return hooking piece 635b that can engage with the hooking engagement portion 628a and is rotatable about the hooking engagement portion 628a. Further, the intermediate member 63 has a hooking engagement portion 628a, and the intermediate member 63 attached to the beam 4 adjacent to the intermediate member 63 has a return hooking piece 635b that can engage with the hooking engagement portion 628a and is rotatable about the hooking engagement portion 628a. Therefore, by simply hooking and rotating the return hooking piece 635b on the hooking engagement portions 628a and 638a, the long member 61 can be arranged at the attachment position to the beam 4. Thereby, the workability of constructing the roof body 6 can be improved.

[0123] In addition, in the present embodiment, the intermediate member 63 has a nut member 601 that is arranged on the end side opposite to the return hooking piece 635b in the width direction orthogonal to the longitudinal direction and can be fixed to the beam 4 with a screw member 101 from above. Thereby, the intermediate member 63 can be attached to the beam 4 by simply fixing only one end portion on one side in the width direction of the intermediate member 63. Therefore, the workability of constructing the roof body 6 can be improved. Further, since it is fixed from above with the screw member 101, the screw member 101 is not visible from below. Therefore, the designability can be improved.

[0124] In addition, in the present embodiment, the long member 61 is composed of a shaped member made of an aluminum material having a hollow structure with a hollow portion. Thereby, by arranging them side by side in a predetermined direction, it is easy to form the upper surface 6a or / and the lower surface 6b in a planar shape. Also, since they can be easily fitted together by arranging them side by side in a predetermined direction, the handling is easy, so the workability can be improved. Further, it can be easily formed into a simple appearance by forming the thickness thin, and the designability can be improved. Also, by configuring the plurality of long members 61 constituting the roof body 6 with shaped members having hollow portions, the roof body 6 itself can be used as a strength member, and there is no need to separately provide a member for providing the strength of the roof body 6. Therefore, the number of parts of the members constituting the roof body 6 can be reduced.

[0125] In addition, in the present embodiment, the upper surface 6a of the roof body 6 is formed in a planar shape. As a result, water easily flows on the upper surface 6a of the roof body 6, and rainwater poured onto the upper surface 6a of the roof body 6 is easily guided in a predetermined direction.

[0126] In addition, in the construction method of the carport 1 of the present embodiment, when attaching the intermediate member 63 adjacent to the gutter forming member 62 (intermediate member 63) to the beam 4, the return hook piece 635b of the intermediate member 63 is hooked on the hook engaging portion 628a (hook engaging portion 638a) of the gutter forming member 62 (intermediate member 63), and the intermediate member 63 is rotated around the hook engaging portions 628a, 638a and the return hook piece 635b to arrange the intermediate member 63 at the attachment position. Therefore, the intermediate member 63 can be arranged at the attachment position to the beam 4 only by hooking and rotating the return hook piece 635b on the hook engaging portions 628a, 638a. Thereby, the workability of constructing the roof body 6 can be improved.

[0127] In addition, in the construction method of the carport 1 of the present embodiment, after the arranging step, on the end side opposite to the hook piece 635b in the width direction orthogonal to the longitudinal direction, the nut member 601 of the intermediate member 63 is fixed to the beam 4 from above by the screw member 101. Thereby, the intermediate member 63 can be attached to the beam 4 only by fixing only one side in the width direction of the intermediate member 63. Therefore, the workability of constructing the roof body 6 can be improved.

[0128] In addition, in the construction method of the carport 1 of the present embodiment, a step of attaching a plurality of long members 61 to the beam 4 in order from the support column 2 side is provided. Therefore, since the long members 61 can be constructed in order from the support column 2 side, alignment of the long members 61 is easy. Also, when arranging the long members 61, the support column 2 is less likely to get in the way. Thereby, the workability of constructing the roof body 6 can be improved.

[0129] Next, the carport 1A according to the second embodiment of the present invention will be described. FIG. 16 is a cross-sectional view showing the fixing structure of the support column 2A and the connecting member 5A and the support column cover member 3A in the carport 1A according to the second embodiment of the present invention. The carport 1A according to the second embodiment is different from the carport 1 according to the first embodiment in the direction in which the screw member 102 for fixing the support column 2A and the connecting member 5A is attached and the surface on which the support column cover member 3A is disposed on the support column 2A. In the description of the second embodiment, the same components as those in the first embodiment are denoted by the same reference numerals, and the description thereof is omitted or simplified.

[0130] In the second embodiment, only on the rear side surface in the front-rear direction of the support column 2A, the lower end portion of the connecting member 5A and the upper end portion of the support column 2A are fixed by four screw members 102 arranged vertically. The support column 2A has a pair of cover mounting walls 22A protruding rearward from the rear side surface. The support column cover member 3A is attached to the pair of cover mounting walls 22A from the rear side of the support column 2A so as to cover the rear side surface of the support column 2A from the rear side of the support column 2A. The guide member 7A is disposed with the lower end side opening 72A inserted into the column side gutter component 20A between the support column 2A and the support column cover member 3A.

[0131] In the carport 1A of the second embodiment, the connecting member 5A is fixed to the support column 2A by the screw member 102 on the rear side surface of the support column 2A. The support column cover member 3A is attached to the rear side surface of the support column 2A. In the second embodiment, the same effects as those in the first embodiment can be achieved.

[0132] Next, the third embodiment of the present invention will be described. FIG. 17 is a cross-sectional view showing a state in which the screw member 101A is provided with the loosening prevention structure 66 in the third embodiment of the present invention. FIG. 18 is a plan view showing a state in which the screw member 101A is provided with the loosening prevention structure 66 in the third embodiment of the present invention.

[0133] The third embodiment is different from the first embodiment in that the anti-loosening structure 66 is provided on the screw member 101A, while the first embodiment has an adhesive for preventing loosening applied to the screw member 101. In this embodiment, the anti-loosening structure 66 is provided on the screw member 101A for fixing the gutter forming member 62, the intermediate member 63, and the tip-side member 64 to the beam 4. As shown in FIG. 17, the anti-loosening structure 66 includes an anti-loosening fitting member 67. The anti-loosening fitting member 67 is fitted to the head of the screw member 101A for fixing the gutter forming member 62, the intermediate member 63, and the tip-side member 64 to the beam 4, thereby preventing the screw member 101A from loosening.

[0134] As shown in FIGS. 17 and 18, the anti-loosening fitting member 67 includes a plate-shaped fitting member body 671 in which a through hole 671a is formed, a plate-shaped extension piece 672 extending laterally from the fitting member body 671, and a locking piece 673 extending upward from the end of the extension piece 672 on the side opposite to the fitting member body 671.

[0135] An anti-loosening fitting uneven edge portion 671b is formed on the periphery of the through hole 671a in the fitting member body 671. By fitting the anti-loosening fitting member 67 onto the head of the screw member 101A from above, the anti-loosening fitting uneven edge portion 671b fits into the corner portion of the head of the screw member 101A. Thereby, when the corner portion of the head of the screw member 101A fits into the anti-loosening fitting uneven edge portion 671b, the anti-loosening fitting member 67 prevents the screw member 101A from loosening.

[0136] When the anti-loosening fitting member 67 is fitted onto the head of the screw member 101A, the locking piece 673 is locked and fixed to the lower end groove 401 formed between the lower end portion of the hollow portion 41 of the beam 4 and the extension plate portion 42. Thereby, when attaching the anti-loosening fitting member 67 to the head of the screw member 101A, by locking the locking piece 673 to the lower end groove 401 of the beam 4 and fixing it, the anti-loosening fitting member 67 can be fixed to the beam 4 in a state where the anti-loosening fitting member 67 is attached to the head of the screw member 101A.

[0137] According to the roof structure of the third embodiment described above, the following effects can be obtained. The roof structure of this embodiment includes a support column 2, a beam 4 connected to the support column 2, and a roof body 6 connected to the beam 4. The roof body 6 has a plurality of long members 61 arranged side by side in the direction in which the beam 4 extends and fitted and connected to each other. The roof structure is provided with a roof body 6 fixed to the beam 4 by screw members 101A with anti-loosening structures 66 applied thereto.

[0138] Therefore, the roof body 6 is fixed to the beam 4 in a state where the screw members 101A fixing the gutter-forming member 62, the intermediate member 63, and the tip-side member 64 are locked by the anti-loosening fitting members 67, and the gutter-forming member 62, the plurality of intermediate members 63, and the tip-side member 64 are fitted and connected to each other. Thus, the fall of the roof body 6 can be suppressed.

[0139] Also, in this embodiment, the anti-loosening structure 66 has an anti-loosening fitting member 67 that is fixed to the beam 4 and fits into the head of the screw member 101A to prevent the screw member 101A from loosening. Thereby, with a simple configuration of fitting the anti-loosening fitting member 67 to the head of the screw member 101A, the loosening of the screw member 101A can be prevented in a state of being fixed to the beam 4.

[0140] Although a preferred embodiment of the carport (roof structure) of the present invention has been described above, the present invention is not limited to the above-described embodiment and can be appropriately modified. For example, in the first embodiment, the connecting member 5 is fixed to the support column 2 on the side surface of the support column 2 on the roof body 6 side, and in the second embodiment, the connecting member 5A is fixed to the support column 2A on the back side surface of the support column 2A. However, it is not limited to these. The connecting member 5 may be fixed to the front side surface of the support column 2 with a screw member, or the connecting member 5 may be fixed to the side surface of the support column 2 opposite to the roof body 6. In these cases, the side surface of the support column fixed with the screw member can be covered with a support column cover member to cover the screw member.

[0141] In the above embodiment, the plurality of long members 61 are each directly fixed to and connected to the beam 4 by the screw members 101 and 105, but the present invention is not limited to this. For example, the plurality of long members 61 may be configured to be connected to the beam 4 via a support member or the like.
