Description

[Technical Field]

[0001] The present invention relates to a roof structure including pillars, beams, and a roof body, and a method for constructing the roof structure. [Background technology]

[0002] Conventionally, a cantilevered carport (roof structure) has been known that includes pillars, beams connected to the pillars, and a roof body connected to the beams (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 panel materials arranged inside the frame. Also known is a carport that includes pillars, beams connected to the pillars, a roof connected to the beams, and a ceiling material that is placed below the roof and has a flat underside (see, for example, Patent Document 2). The ceiling material described in Patent Document 2 is placed below the roof so that the underside of the roof is not visible. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Patent No. 5185523 [Patent Document 2] Japanese Patent Application Publication No. 2015-132081 Summary of the Invention [Problem to be solved by the invention]

[0004] The roof of the carport described in Patent Document 1 is composed of a frame and panel materials, so the frame is thicker than the panel materials, and the unevenness of the frame and panel materials is visible from the outside. Therefore, it is desirable to improve the design. Furthermore, in the carport described in Patent Document 1, when attaching the panel materials to the frame at the carport construction site, the panel materials are large and difficult to handle. Therefore, it is desirable to improve the construction of the roof. In addition, the carport described in Patent Document 2 has a roof made of panels attached to a frame, and a ceiling material with a flat underside is placed below it, creating a double structure of the roof and ceiling material. In the carport described in Patent Document 2, the roof has a double structure of the roof and ceiling material, which increases the number of parts and tends to make the structure more complicated. This increases manufacturing costs and makes the construction of the roof more time-consuming. Therefore, there is a demand for a carport (roof structure) that can improve both design and construction efficiency.

[0005] An object of the present invention is to provide a roof structure and a method for constructing a roof structure that can improve design and ease of construction. [Means for solving the problem]

[0006] The present invention relates to a roof structure (for example, a carport 1 described below) comprising a pillar material (for example, a support 2 described below), a beam (for example, a beam 4 described below) connected to the pillar material, and a roof body (for example, a roof body 6 described below) connected to the beam, which has a plurality of long materials (for example, a long shaped material 61 described below) arranged in a predetermined direction and whose underside (for example, a underside 6b described below) is formed flat.

[0007] It is also preferable that the plurality of elongated members are arranged side by side in the direction in which the beam extends.

[0008] It is also preferable that each of the plurality of elongated members is directly fixed to the beam.

[0009] It is also preferable that the roof body be arranged below the beams and suspended from the beams.

[0010] Furthermore, it is preferable that the first long member (e.g., the gutter constituent member 62, intermediate member described below) attached to the beam among the plurality of long members has a first engagement portion (e.g., the hook engagement portions 628a, 638a described below) arranged at one end side in the width direction perpendicular to the longitudinal direction, and the second long member (e.g., the intermediate member described below) attached to the beam adjacent to the first long member among the plurality of long members has a second engagement portion arranged at the end side of the first long member in the width direction perpendicular to the longitudinal direction, which is engageable with the first engagement portion and can rotate around the first engagement portion.

[0011] Furthermore, it is preferable that the second elongated material has a screw fixing portion (e.g., the nut member 601 described below) that is arranged on the end side opposite the second engagement portion in the width direction perpendicular to the longitudinal direction and can be fixed to the beam from above with a screw member (e.g., the screw member 101 described below).

[0012] Furthermore, it is preferable that the elongated member is made of a hollow aluminum material.

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

[0014] This relates to a carport construction method for a roof structure, which includes an arrangement step in which, when attaching the second long material adjacent to the first long material to the beam, the second engaging portion of the second long material is hooked onto the first engaging portion of the first long material, and the second long material is rotated around the first engaging portion and the second engaging portion to place the second long material in an attachment position.

[0015] Furthermore, it is preferable that the second long material has a screw fixing portion that is arranged on the end side opposite the second engagement portion in the width direction perpendicular to the longitudinal direction and can be fixed to the beam from above with a screw member, and that after the arrangement process, a fixing process is provided in which the screw fixing portion of the second long material is fixed to the beam from above with a screw member at the end side opposite the second engagement portion in the width direction perpendicular to the longitudinal direction.

[0016] It is also preferable to include a step of attaching the plurality of elongated members to the beam in order from the pillar member side. [Effects of the Invention]

[0017] According to the present invention, it is possible to provide a roof structure and a method for constructing a roof structure that can improve design and ease of construction. [Brief explanation of the drawings]

[0021] In the description of this embodiment, the direction in which the multiple long members (long members) 61 constituting the roof body 6 of the carport 1 extend is also referred to as the front-to-rear direction, and in Figures 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. The direction perpendicular to the front-to-rear direction in which the long members (long members) 61 extend is also referred to as the left-to-right direction. In the left-to-right direction, the side of the support 2 when viewed from the front side is also referred to as the right side of the carport 1, and the side opposite the support 2 when viewed from the front side is also referred to as the left side of the carport 1. In the direction in which the beams 4 extend, the side of the support 2 is also referred to as the base end side of the carport 1, and the side opposite the support 2 is also referred to as the tip side of the carport 1.

[0022] First, the overall structure of the carport 1 of this embodiment will be described. As shown in Figures 1 and 2, the carport 1 of this embodiment is a so-called cantilevered carport in which a roof body 6 is supported by a pair of support columns 2 at the base end side in the left-right direction (the right side in Figures 1 and 2). The carport 1 of this embodiment is also configured as a suspended structure in which the roof body 6 is suspended and connected to the lower part (below) of the beams 4 connected to the support columns 2.

[0023] 1 to 6, the carport 1 of this embodiment comprises a pair of posts 2 (post members) erected on the ground 11, post cover members 3 (cover members) attached to the sides of the pair of posts 2, beams 4 extending from the upper ends of the posts 2 in a direction intersecting the posts, L-shaped connecting members 5 connecting the posts 2 and the beams 4, a roof body 6 connected to the lower part of the beam 4, an L-shaped guide member 7 (see FIG. 3) that guides water that has flowed over the top surface of the roof body 6 toward the posts 2, a pair of roof body side cover members 8 (cover members), and a roof body tip cover member 65. The posts 2 and beams 4 are formed from extruded aluminum profiles and have a hollow structure with a hollow cross section.

[0024] As shown in FIG. 1, the pair of support pillars 2 are arranged on one side of the carport 1 in the left-right direction (the right side in FIG. 1) and spaced apart in the front-rear direction of the carport 1. The support pillar 2 is formed to extend in the vertical direction, and as shown in Figure 7, has a hollow support pillar-side hollow portion 21 whose cross section is formed in the shape of a square tube, and a pair of cover mounting walls 22 that protrude toward the roof body 6 from the side surface of the support pillar-side hollow portion 21 facing the roof body 6 and extend in the vertical direction. A support pillar cover member 3 is attached to the pair of cover mounting walls 22. A support pillar cap 201 is arranged on the upper end of the support pillar 2 so as to cover the opening at the upper end of the support pillar 2.

[0025] As shown in Figure 1, the support 2 on one side in the front-to-rear direction (the front side in Figure 1) of a pair of support posts 2 has a lower end opening 23 formed at its lower end near the ground 11. The lower end opening 23 is cut out so that the side facing the roof body 6 is open and is recessed from the roof body 6 side toward the inside of the support post 2. A drainage receiving cover member 24 is disposed in the lower end opening 23. The drainage receiving cover member 24 is provided with a discharge opening 24a that opens outward on the front side in the front-to-rear direction. The discharge opening 24a discharges water flowing through a support post side gutter component 20 (described below) formed by the support post 2 and the support post cover member 3 to the outside on the front side.

[0026] As shown in Figure 4, the pillar cover member 3 is attached to a pair of cover mounting walls 22 on the pillar 2. The pillar cover member 3 is composed of a single cover member extending in the vertical direction. The pillar cover member 3 is attached to the pair of cover mounting walls 22 (see Figure 7) so as to cover one side of the pillar 2 facing the roof body 6, and the screw members 102 that secure the pillar 2 to the connecting member 5 (described later). In other words, the pillar cover member 3 is composed of a single cover member without being divided, and is arranged on only one side of the pillar 2 so as to cover four screw members 102 that secure only one side of the connecting member 5. Water flowing over the upper surface 6a of the roof body 6 flows in and flows between the pillar 2 and the pillar cover member 3, so the pillar 2 and pillar cover member 3 are configured as a pillar side gutter component 20 (pillar side gutter structure). In this embodiment, no rain gutter hose or the like is disposed between the support pole 2 and the support pole cover member 3, and the support pole 2 and the support pole cover member 3 alone form a vertical gutter.

[0027] Water discharged from a roof body side gutter component 60 (described later) of the roof body 6 flows between the support pillar 2 and the support pillar cover member 3 (support pillar side gutter component 20). The support pillar side gutter component 20 is not visible from outside the carport 1 because the side of the support pillar 2 facing the roof body 6 is covered by the support pillar cover member 3. Therefore, the fact that the support pillar 2 has a gutter function is not visible from the outside, improving the design.

[0028] As shown in Figure 1, the pair of beams 4 are arranged spaced apart in the front-to-rear direction of the carport 1. Each of the pair of beams 4 extends in the left-to-right direction and is formed with a downward slope that descends toward the support column 2. The base end (right end) of each of the pair of beams 4 is connected to the upper end of the support 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 formed in a rectangular cylindrical cross section, an extending 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 increases from the tip side toward the base end side (the support 2 side) so that the upper end portion on the tip side is slanted and cut out. Therefore, when 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 makes it difficult to see from the ground 11 side below the tip side of the roof body 6. Therefore, since the beam 4 is difficult to see from the ground 11 side below the tip side of the roof body 6, the design can be improved.

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

[0032] 5 and 6, the extension plate portion 42 has a plurality of screw holes 421 formed side by side in the left-right direction, into which screw members 101 are inserted to fix the roof body 6 to the beam 4. The plurality of screw holes 421 are formed from the base end on the support 2 side toward the tip end of the beam 4, and include a first gutter member mounting screw hole 421a, a hook portion mounting screw hole 421b, and a second gutter member mounting screw hole 421c, followed by a plurality of one-side mounting screw holes 421d formed side by side.

[0033] The first gutter member mounting screw hole 421a is provided to fix the base end side portion of the gutter constituent member 62 (described later) in the long member 61 and the extension plate portion 42 of the beam 4 with a screw member 105, as shown in FIG. The second gutter member mounting screw hole 421c is provided for fixing the tip end side portion of the gutter constituent member 62 (described later) in the long member 61 and the extension plate portion 42 of the beam 4 with a screw member 101. The hook portion mounting screw hole 421b is provided to fix the hook portion 110 (see Figure 5) with the screw member 106, which is used to hook and temporarily place the gutter component shape 62 of the long extrusion 61 (described later) when attaching the gutter component shape 62 of the long extrusion 61 to the beam 4. The one-side mounting screw hole 421d is provided to fix the tip end portion of the intermediate extrusion 63 and the extension plate portion 42 of the beam 4 with a screw member 101 when attaching the intermediate extrusion 63 of the long extrusion 61 to the beam 4, as shown in Figure 6.

[0034] 4, the connecting member 5 is formed in an L-shape overall when the carport 1 is viewed in the front-to-rear direction, and has a cylindrical cross section. The connecting member 5 has a vertical cylindrical portion 51 extending in the up-down direction, and a horizontal cylindrical portion 52 extending so as to slope downward on the vertical cylindrical portion 51 side and connected to the vertical cylindrical portion 51.

[0035] The connecting member 5 connects the support pillar 2 and the beam 4. The lower end (one side) of the vertical tube portion 51 of the connecting member 5 is inserted into the support pillar-side hollow portion 21 of the support pillar 2 from the upper end side of the support pillar 2, and is fixed to the support pillar 2 on only one side of the support pillar 2 facing the roof body 6 with four screw members 102 lined up in the vertical direction. The tip end (other side) of the horizontal tube portion 52 of the connecting member 5 is inserted into the beam-side hollow portion 41 of the beam 4, and is fixed by two screw members 103 from above and one screw member 104 from below.

[0036] As shown in Figure 4, the four screw members 102 arranged in the vertical direction that secure the support pillar 2 and the connecting member 5 secure the support pillar 2 and the connecting member 5 at four locations on one side of the support pillar 2 that faces the roof body 6. The screw members 102 exposed on one side of the support pillar 2 that faces the roof body 6 are covered by the support pillar cover member 3 that covers one side of the support pillar 2 and is attached to the support pillar 2 so that they are not visible from the outside. This makes the screw members 102 invisible from the outside, improving the design.

[0037] The multiple screw members 103, 104 that secure the beams 4 and the connecting member 5 secure the beams 4 and the connecting member 5 at two locations on the upper surface of the beams 4 and one location on the lower surface of the beams 4. The two screw members 103 on the upper surface of the beams 4 are positioned so as to be exposed upward and are therefore not visible from below the carport 1. The one screw member 104 on the lower surface of the beams 4 is not visible from below the carport 1 because the roof body 6 is positioned below the beams 4.

[0038] As shown in Fig. 4, the roof body 6 has a hanging structure in which the roof body 6 is hung from the lower parts of a pair of beams 4, and is attached (connected) to the lower parts of the pair of beams 4. The roof body 6 is made up of a plurality of long members (long members) 61 that are arranged side by side in the direction in which the beams 4 extend and are fitted and connected to each other.

[0039] Each of the multiple long members 61 extends in the front-to-rear direction of the carport 1 (a direction perpendicular to the extension direction of the beams 4) and has a predetermined thickness. Each of the multiple long members 61 is formed from an extruded aluminum member and has a hollow structure with a hollow cross section. The roof body 6 has a flat upper surface 6a and a flat lower surface 6b. The roof body 6 is arranged with a downward slope toward the support columns 2, and the upper surface 6a and the lower surface 6b are also formed with a downward slope toward the support columns 2. By connecting multiple long members 61 formed from extruded aluminum members to form the roof body 6, the multiple long members 61 can be used as surface materials for the roof body 6 and the strength of the roof body 6 can be ensured. Furthermore, by forming the multiple long members 61 that form the roof body 6 from members with hollow portions, the roof body 6 itself can be used as a strength member, eliminating the need for additional members to increase the strength of the roof body 6. Therefore, the number of parts that make up the roof body 6 can be reduced.

[0040] As shown in Figure 4, the multiple long members 61 that make up the roof body 6 are composed of a gutter-forming member 62 located at the end closest to the base end on the support pillar 2 side, a tip-end side member 64 located closest to the tip end, and multiple intermediate members 63 that are located between the gutter-forming member 62 and the tip-end side member 64. The multiple long members 61 are each directly fixed and connected to the beam 4 by screw members 101, 105. In this embodiment, an adhesive for preventing loosening is applied to the screw members 101, 105. It is noted that it is not necessary to apply an adhesive for preventing loosening to the screw members 101, 105.

[0041] The gutter-forming shapes 62 are arranged in parallel at the end of the roof body 6 on the support pillar 2 side in the direction in which the multiple long extrusions 61 are lined up. The gutter-forming shapes 62 are long extrusions that are arranged at the end of the multiple long extrusions 61 on the support pillar 2 side in the direction in which the multiple long extrusions 61 are lined up, and are configured as a roof body side gutter structure. As shown in FIG. 5 , the gutter-forming shapes 62 are formed from long extrusions that open upward at the top. In this embodiment, the gutter-forming shapes 62 are formed from solid materials that do not have a hollow portion, and are formed with a U-shaped cross section that opens at the top. However, the gutter-forming shapes 62 are not limited to this, and may be formed into a shape that opens at the top by cutting out the top surface of a long extrusion made of aluminum material with a hollow structure.

[0042] The gutter-forming shape member 62 constitutes a roof body side gutter forming part 60 at the end closest to the base end on the support pillar 2 side of the roof body 6, which receives and circulates water that flows down the upper surface 6a of the roof body 6 toward the base end and reaches the end on the base end side. The roof body side gutter forming part 60 is arranged at the end on the downstream side of the water flowing over the upper surface 6a of the roof body 6. In this embodiment, the roof body side gutter forming part 60 is arranged at the downward sloping end of the roof body 6, at the end of the roof body 6 on the support pillar 2 side of the base end.

[0043] Since the roof body side gutter component 60 is open at the top, when the roof body side gutter component 60 is viewed from below the roof body 6, only the flat (planar) underside of the elongated member 61 is visible, and the gutter can be configured without making it clear that there is a gutter on the upper surface 6a of the roof body 6, thereby improving the design.

[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] 5, the base-end-side upper inward extending piece 623 protrudes inward from the inner surface on the upper side of the gutter forming portion 621 at the base end side of the gutter forming portion 621. The base-end-side upper inward extending piece 623 has a mounting screw hole 623a formed therein into which the screw member 101 is screwed.

[0050] The tip-side upper inward extending piece 624 protrudes inward from the upper end of the gutter-constituting portion 621 on the side opposite the base end of the gutter-constituting portion 621 in the width direction. A hooking protrusion 624a protruding from the lower end is formed at the tip of the tip-side upper inward extending piece 624. When attaching the gutter-constituting shape member 62 to the beam 4, the hooking protrusion 624a of the gutter-constituting shape member 62 can be hooked onto the rising plate 110d of the hook portion 110 fixed to the underside of the extension plate portion 42 of the beam 4, thereby temporarily placing the gutter-constituting shape member 62 on the underside of the extension plate portion 42 of the beam 4. Furthermore, by rotating the gutter-constituting shape member 62 about the hooking protrusion 624a with the hooking protrusion 624a of the gutter-constituting shape member 62 hooked onto the rising plate 110d of the hook portion 110 fixed to the underside of the extension plate portion 42 of the beam 4, the gutter-constituting shape member 62 can be positioned in the attachment position. As shown in Figure 5, the hook portion 110 has an attachment plate 110a attached to the underside of the extension plate portion 42 of the beam 4, a vertical extension plate 110b extending downward from the tip end of the attachment plate 110a, a bottom plate 110c extending from the lower end of the vertical extension plate 110b toward the tip end, and a rising plate 110d rising from the tip end of the bottom plate 110c.

[0051] The hooking protrusion 624a of the gutter-constituting shape member 62 is positioned above the hook portion 110 when the gutter-constituting shape member 62 is fixed to the beam 4. As a result, even if the screw members 105, 101 that secure the gutter-constituting shape member 62 come loose when the gutter-constituting shape member 62 is fixed to the beam 4, the hooking protrusion 624a can be hooked onto the rising plate 110d of the hook portion 110, preventing the gutter-constituting shape member 62 from falling.

[0052] 5, the drip fin 625 protrudes downward from the lower end of the gutter forming part main body 622 on the base end side of the roof body 6 in the gutter forming part main body 622. The position of the lower end 625a of the drip fin 625 is located lower than the upper end 31 of the support pole cover member 3 in the vertical direction.

[0053] The drain fin 625 transmits water guided from the water receiving flow path section 822 of the roof body side cover member 8 described later, and drops the water transmitted by the water receiving flow path section 822 of the roof body side cover member 8 below the roof body 6 so that it does not flow around to the underside 6b of the roof body 6.

[0054] Furthermore, the position of the lower end 625a of the drainer fin 625 is located below the upper end 31 of the pole cover member 3 in the vertical direction, so the drainer fin 625 can cover the portion where the guide member 7 is located above the upper end 31 of the pole cover member 3. This allows the guide member 7 to be hidden from the outside, improving the design.

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

[0056] The tip-side upper outward extending piece 627 extends toward the tip side from the upper end of the gutter-forming section main body 622 on the tip side (left side) of the roof body 6. The tip-side upper outward extending piece 627 is arranged at the upper end of the tip-side end of the gutter-forming shape member 62, and constitutes a fixing part that is fixed to the beam 4 by a screw member 101. The tip-side upper outward extending piece 627 is formed above the hook engagement portion 628a of the intermediate shape member 63. A screw hole 627a is formed in the tip-side upper outward extending piece 627. When attaching the tip-side end of the gutter-forming shape member 62 to the beam 4, a screw member 101 is inserted from above the second gutter-form member mounting screw hole 421c of the extension plate portion 42 of the beam 4 and is inserted into the screw hole 627a, and the screw member 101 is screwed into a nut member 601 arranged below the tip-side upper outward extending piece 627. The tip-side upper outward extending piece 627 is fixed to the extending plate portion 42 of the beam 4 by a screw member 101 above the hook engaging portion 628a of the intermediate frame 63.

[0057] A lateral extending wall 627b and a downward extending wall 627c are formed at the end of the tip side (left side) of the roof body 6 of the tip side upper outward extending piece 627. A tip side locking piece 627d protrudes laterally from the side surface of the base end side of the downward extending wall 627c. At a position opposite to the tip side locking piece 627d, a base side locking piece 627e is formed, which extends downward from below the tip side upper outward extending piece 627 and is bent midway toward the tip side locking piece 627d. Below the tip-side upper outward extending piece 627, the nut member 601 is locked by the tip-side locking piece 627d and the base-end side locking piece 627e.

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

[0059] The tip-side lower outer piece 628 extends toward the tip side (left side) from the lower end of the tip side (left side) of the roof body 6 in the gutter configuring part main body 622. A hook engagement portion 628a (first engagement portion, first fitting portion) that protrudes upward is formed at the tip side (left side) end of the tip-side lower outer piece 628.

[0060] 5, the hook engagement portion 628a is formed at the lower end of the gutter-constituting frame 62 at the end on the tip side (one end side in the width direction perpendicular to the longitudinal direction) of the gutter-constituting frame 62 attached to the beam 4. The hook engagement portion 628a rises upward from the tip-side lower outer piece 628 arranged at the lower end of the gutter-constituting frame 62 at the end on the tip side (one end side in the width direction perpendicular to the longitudinal direction) of the gutter-constituting frame 62 attached to the beam 4, and is formed in a T-shape at the rising upper end extending in the width direction perpendicular to the longitudinal direction. The hook engagement portion 628a has a rising portion 628b, a first hook portion 628c (hook portion) extending from the upper end of the rising portion 628b toward the tip side, and a second hook portion 628d (hook portion) extending from the upper end of the rising portion 628b toward the opposite side from the tip (the base end side, the support side).

[0061] The first hook portion 628c of the hook engagement portion 628a of the intermediate extrusion 63 is engageable with a base end lower protruding piece 636 (second fitting portion) protruding toward the base end from the side surface of the lower end portion on the base end side of the adjacent intermediate extrusion 63. In addition, the second hook portion 628d of the hook engagement portion 628a of the intermediate extrusion 63 is engageable with a return hook portion 635b (second engagement portion, second fitting portion) (described later) of a hook extension piece 635 formed at the end portion on the base end side (the end side on the gutter-constituting extrusion 62 side in the width direction perpendicular to the longitudinal direction) of the adjacent intermediate extrusion 63.

[0062] Water that overflows from a middle gutter component 610 (described below) (first second water stop portion) of the intermediate extrusion 63 of the adjacent long extrusion 61 flows onto the upper surface of the tip-side lower outer piece 628. The upper surface of the tip-side lower outer piece 628 forms a lower gutter component 620 located at the lower level in the vertical direction inside the roof body 6. The lower gutter component 620 functions as a gutter that allows water to flow and also functions as a water stop portion (second second water stop portion). The lower gutter component 620 receives water that has passed through the packing member 602 and been received by the middle gutter component 610 and overflows from the middle gutter component 610 (first second water stop portion), and allows the received water to flow to both end sides in the front-to-rear direction. In other words, the roof body 6 has a two-stage gutter structure at the connecting portion of adjacent long extrusions 61, and is equipped with a middle gutter component 610 that is arranged on the upper side and receives water on the upper side, and a lower gutter component 620 that is arranged on the lower side and receives water that overflows from the middle gutter component 610 on the lower side. The middle gutter component 610 and the lower gutter component 620 extend in the direction in which the connecting portion of adjacent long extrusions 61 extends, i.e., along the longitudinal direction of the long extrusions 61.

[0063] The gutter-forming shape member 62 is fixed to the beam 4 by moving the screw member 105 from above at the base end side, and the screw member 105 passed through the first gutter-forming shape member mounting screw hole 421a of the extending plate portion 42 of the beam 4 is screwed into the mounting screw hole 623a of the base-end upper inward extending piece 623. In addition, in the gutter-forming shape member 62, as shown in Fig. 5, the nut member 601 is attached to the inside of the gutter-forming shape member 62 at the tip end side of the gutter-forming shape member 62. The gutter-forming shape member 62 is fixed to the beam 4 by moving the screw member 101 from above at the tip end side, and the screw member 101 is inserted through the one-side mounting screw hole 421d of the extending plate portion 42 of the beam 4 and the screw hole 627a of the tip end upper outward extending piece 627 and screwed into the nut member 601.

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

[0065] As shown in Fig. 5, an opening 639 that opens downward is formed below the base-side end of the middle gutter section 634. The opening 639 is formed by an end side 631a extending in the vertical direction and located on the base-side of the first intermediate hollow section 631 of the middle gutter section 634, and an L-shaped hook extension piece 635. At the opening edge of the opening 639, opposing protrusions 639a (second fitting portions) are formed that protrude from the opening edge of the opening 639 toward the inside of the opening 639 in an opposing relationship. In this embodiment, the opposing protrusions 639a are constituted by the base-side lower protrusion 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 constituent shape members 62 and intermediate shape members 63 configured as described above, when adjacent gutter constituent shape members 62 and intermediate shape members 63 are fitted together, the first hook portion 628c of the hook engagement portion 628a of the gutter constituent shape member 62 engages (fits) with the base end side lower protruding piece 636 of the adjacent intermediate shape member 63, and the second hook portion 628d of the hook engagement portion 628a of the gutter constituent shape member 62 engages (fits) with the return hook portion 635b (described later) of the hook extension piece 635 of the adjacent intermediate shape member 63, so that the adjacent gutter constituent shape members 62 and intermediate shape members 63 are fitted together. In this embodiment, when adjacent gutter constituent shapes 62 and intermediate shapes 63 are connected, the hook engagement portion 628a (first hook portion 628c and second hook portion 628d) of the gutter constituent shape 62 is positioned inside the opening 639 of the adjacent intermediate shape 63, and hooks onto and engages with the opposing protrusion 639a (base end side lower protrusion piece 636, return hook piece 635b of the L-shaped hook extension piece 635) so as to restrict movement in the vertical direction.

[0067] The packing mounting recess 633 is disposed opposite the downward extending wall 627c of the adjacent gutter constituent shape member 62 on the base end side. The packing mounting recess 633 extends in the direction in which the connecting portion of adjacent elongated shape members 61 extends, i.e., along the longitudinal direction of the elongated shape members 61. A packing member 602 is attached to the packing mounting recess 633. When attached to the packing mounting recess 633, the packing member 602 presses against the downward extending wall 627c of the adjacent gutter constituent shape member 62 on the base end side. The packing member 602 is disposed at the connecting portion between the gutter constituent shape member 62 and the intermediate shape member 63, and functions as a water stop portion (first water stop portion).

[0068] The middle gutter section 634 has a bottom wall section 634a and an upright piece 634b. The middle gutter section 634 constitutes a middle gutter component 610 located in the middle section in the vertical direction inside the roof body 6. The middle gutter component 610 has a gutter function to allow water to flow, and also functions as a water stopping section (first second water stopping section). The middle gutter component 610 receives water that has passed through the packing member 602 and was not able to be stopped by the packing member 602, and allows the received water to flow to both end sides in the front-to-rear direction.

[0069] The L-shaped hook extension piece 635 has a downward extending piece 635a and a return hook piece 635b (second fitting portion, hook protrusion) that extends from the lower end of the downward extending piece 635a back toward the first intermediate hollow portion 631. The return hook piece 635b is engageable with a hook engagement portion 628a (first fitting portion) formed on the end portion on the tip side of the adjacent gutter constituent shape member 62. When engaged with the hook engagement portion 628a, the return hook piece 635b is rotatable around the hook engagement portion 628a.

[0070] When attaching an adjacent intermediate extrusion 63 next to a gutter-forming extrusion 62 connected to a beam 4, the intermediate extrusion 63 can be temporarily placed below the beam 4 by hooking the hook extension piece 635 of the intermediate extrusion 63 onto the hook engagement portion 628a of the gutter-forming extrusion 62 attached to the beam 4. Furthermore, with the hook extension piece 635 of the intermediate extrusion 63 hooked onto the hook engagement portion 628a of the gutter-forming extrusion 62, the intermediate extrusion 63 can be placed in the attachment position by rotating the intermediate extrusion 63 around the tip of the hook extension piece 635. When the intermediate extrusion 63 is placed in the mounting position, the intermediate extrusion 63 is attached to the tip side of the beam 4 of the gutter component extrusion 62 with the hook extension piece 635 of the intermediate extrusion 63 engaged with the hook engagement portion 628a of the gutter component extrusion 62.

[0071] The tip-side upper outward extending piece 637 and tip-side lower outer piece 638 of the intermediate extrusion 63 are similar in structure to the tip-side upper outward extending piece 627 and tip-side lower outer piece 628 of the gutter-forming extrusion 62, except for the points that will not be described. Therefore, the structures of the tip-side upper outward extending piece 637 and tip-side lower outer piece 638 of the intermediate extrusion 63 are assigned the same symbols in Figure 6 as those of the structure of the gutter-forming extrusion 62, and description thereof will be omitted.

[0072] 6, the nut member 601 is attached to the inside of the intermediate extrusion 63 at the tip end side of the intermediate extrusion 63 (the end side opposite the return hook piece 635b (second engagement portion) in the width direction perpendicular to the longitudinal direction). At the tip end side, the intermediate extrusion 63 is fixed to the beam 4 by the screw member 101 being moved from above, and the screw member 101 being inserted into the one-side mounting screw hole 421d of the extension plate portion 42 of the beam 4 and the screw hole 637a of the tip end side upper outward extension piece 637 being screwed into the nut member 601.

[0073] Furthermore, among the multiple intermediate extrusions 63 arranged successively, the configuration of the intermediate extrusion 63 arranged adjacent to the tip end side of the intermediate extrusion 63 connected to the beam 4 is similar to the configuration of the intermediate extrusion 63 arranged adjacent to the tip end side of the gutter-forming extrusion 62 connected to the beam 4. Therefore, a description of the configuration of the intermediate extrusion 63 arranged adjacent to the intermediate extrusion 63 will be omitted.

[0074] When attaching an adjacent intermediate extrusion 63 next to an intermediate extrusion 63 connected to a beam 4, similar to when attaching the intermediate extrusion 63 next to a gutter-constituting extrusion 62, the intermediate extrusion 63 can be temporarily placed below the beam 4 by hooking the hook extension piece 635 (second engagement portion) of the intermediate extrusion 63 to the hook engagement portion 638a (first engagement portion) of the intermediate extrusion 63. Furthermore, with the hook extension piece 635 of the intermediate extrusion 63 hooked to the hook engagement portion 638a of the intermediate extrusion 63, the intermediate extrusion 63 can be rotated around the tip of the hook extension piece 635, thereby placing the intermediate extrusion 63 at the attachment position. When the adjacent intermediate extrusion 63 is placed in the mounting position, the adjacent intermediate extrusion 63 is mounted on the tip side of the beam 4 of the already mounted intermediate extrusion 63 with the hook extension piece 635 of the adjacent intermediate extrusion 63 fitted into the hook engagement portion 638a of the already mounted intermediate extrusion 63.

[0075] As shown in FIG. 4, the tip-side extrusion 64 is disposed at the tip end of a plurality of intermediate extrusions 63 connected to the beam 4. The tip-side extrusion 64 has one hollow portion 641. Furthermore, the shape of the base end side of the tip-side extrusion 64 on the support 2 side is the same as the shape of the intermediate extrusion 63 on the support 2 side, and therefore the description of the intermediate extrusion 63 will be used and its description will be omitted. Furthermore, when an adjacent tip-side extrusion 64 is attached next to an intermediate extrusion 63 connected to the beam 4, it is the same as when the intermediate extrusion 63 is attached next to the gutter-forming extrusion 62. When the tip-side profile 64 is positioned at the mounting position, the tip-side profile 64 is attached to the tip side of the beam 4 of the intermediate profile 63 adjacent to the tip-side profile 64, with the hook extension piece (not shown) of the tip-side profile 64 engaged with the hook engagement portion 638a of the intermediate profile 63.

[0076] 8 and 9, the tip end side member 64, which is located at the tip end side of the multiple long members 61 constituting the roof body 6, has both longitudinal ends of the tip end side member 64 fixed to the respective top cover parts 81 of a pair of roof body side cover members 8 (described later) by screw members 107. As shown in FIG. 1, the pair of roof body side cover members 8 extend in a direction perpendicular to (intersecting with) the longitudinal direction of the tip end side member 64 (the direction in which the beam 4 extends) at both longitudinal ends of the tip end side member 64 (both longitudinal ends of the roof body 6).

[0077] In the roof structure configured as above, as shown in Figure 4, the multiple long members 61 in the roof body 6 are connected in a line from the base end side to the tip end side of the beam 4 in the order of a gutter-forming member 62, multiple intermediate members 63, and tip end member 64. The gutter-forming member 62, multiple intermediate members 63, and tip end member 64 are each fitted and connected at the base end side of the beam 4, and are fixed to the beam 4 at the tip end side by screw members 101.

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

[0079] As shown in FIG. 1, the pair of roof body side cover members 8 are arranged at both ends of the long extrusion 61, extending in a direction perpendicular to (intersecting with) the longitudinal direction of the long extrusion 61. The pair of roof body side cover members 8 are arranged at both ends in the front-to-rear direction of the roof body 6 so as to cover the sides of the long extrusion 61. Each of the pair of roof body side cover members 8 extends along the inclination direction of the roof body 6, with the support column 2 side sloping downward. 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 top cover part 81 is formed to have a width in the left-right direction, and is formed in the shape of a plate that extends in the left-right direction along the inclination direction of the roof body 6. The top cover part 81 is positioned by being engaged with the top surface 6a of the roof body 6.

[0081] The side cover parts 82 are connected to the outside of the side parts of the ends of the top cover part 81, and are formed to have a width in the vertical direction, and are formed in the shape of a plate that extends in the left-right direction along the inclination direction of the roof body 6. The side cover parts 82 are arranged so as to cover the sides of the ends of the roof body 6 in the front-to-rear direction.

[0082] The side cover portion 82 has an upper protrusion 821 that protrudes upward, a water receiving flow path portion 822 (third water stopping portion) formed on the lower side and extending inward from the inner surface, a water drain protrusion portion (water drain fin) 823 that protrudes downward from the lower part of the water receiving flow path portion 822, and two protrusion 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 section 822 receives water that is led out from the middle gutter component 610 and the lower gutter component 620 and flows toward the front-to-rear ends of the roof body 6. The water receiving channel section 822 forms a channel for water to flow from the tip end side to the base end side of the roof body 6, and also functions as a water stopper section that stops the water. The water received in the water receiving channel section 822 flows toward the base end because the side cover section 82 is configured with a downward slope that slopes toward the base end. The water that is flowed toward the base end side of the roof body 6 by the water receiving channel section 822 falls below the roof body 6 at the end on the base end side.

[0084] Here, a drip fin 625 is arranged on the base end side of the side cover portion 82, extending downward from the lower end of the gutter constituent member 62 formed to extend in a direction perpendicular to the side cover portion 82. Therefore, a portion of the water flowing over the upper surface of the water receiving channel portion 822 of the side cover portion 82 is transmitted to the drip fin 625. The water transmitted from the water receiving channel portion 822 of the side cover portion 82 falls from the drip fin 625 below the roof body 6 on the base end side of the roof body 6.

[0085] In the carport 1 configured as described above, the lower surface 6b is flat when the roof body 6 is viewed from below, which improves the design. Furthermore, because the roof body 6 is constructed by lining up multiple long members 61, it can be constructed without using a frame (frame body). This allows the thickness of the roof body 6 to be thinner than when a frame (frame body) is used, and also allows the underside 6b of the roof body 6 to be flat with no irregularities.

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

[0087] Furthermore, since the roof body 6 is constructed by arranging a plurality of long members 61, the manufacturing cost can be reduced compared to a roof body constructed with a double structure consisting of a roof body and a ceiling material with a flat underside. Furthermore, since the roof body 6 is disposed below the beams 4 and suspended from the beams 4, the beams 4 located above the roof body 6 are hidden by the roof body 6 when the carport 1 is viewed from below, making them difficult to see. This improves the design of the carport 1.

[0088] Next, a method for constructing a carport will be described with reference to FIGS. First, as shown in Fig. 10, the support pillar 2 is installed and the beam 4 is connected to the support pillar 2. Specifically, after the lower end of the support pillar 2 is fixed to the ground 11, the lower end of the L-shaped connecting member 5 is inserted into the upper end of the support pillar-side hollow portion 21 of the support pillar 2. The lower end of the connecting member 5 and the upper end of the support pillar 2 are fixed together with four screw members 102 aligned vertically on the side surface of the upper end of the support pillar 2 facing the roof body 6.

[0089] Next, as shown in Figure 10, the support pole cover member 3 is attached to the side surface of the support pole 2 facing the roof body 6 so as to cover the four screw members 102. This makes the four screw members 102 that secure the connecting member 5 to the upper end of the support pole 2 invisible from the outside, thereby improving the design.

[0090] Furthermore, the pillar cover member 3 is arranged on only one side of the pillar 2 so as to cover the four screw members 102 that secure only one side of the connecting member 5 (see FIG. 4). This allows for a reduction in the number of parts and costs compared to providing cover members on both sides of the pillar 2. Furthermore, because the pillar cover member 3 only needs to be attached to one side of the pillar 2, the ease of installation for attaching the pillar cover member 3 is improved. Furthermore, compared to providing cover members on both sides of the pillar 2, the width of the pillar 2 can be prevented from increasing.

[0091] Furthermore, the support pole cover member 3 is composed of a single cover member that extends in the vertical direction. Therefore, compared to a configuration consisting of multiple cover members, the number of parts can be reduced and costs can be reduced. Furthermore, because the support pole cover member 3 is composed of a single cover member, installation work is easy and workability is improved. Furthermore, because the support pole cover member 3 is composed of a single cover member, the design can be improved compared to a configuration consisting of multiple cover members where the cover members are arranged separately.

[0092] Water flows between the side surface of the support pillar 2 and the support pillar cover member 3. The side surface of the support pillar 2 and the support pillar cover member 3 form a support pillar side gutter component 20. The support pillar side gutter component 20 is not visible from the outside, which improves the design. Furthermore, the support column cap 201 is fixed to the upper end of the connecting member 5 by screwing so as to cover the opening at the upper end of the support column 2.

[0093] Next, the lateral end portion on the other end side of the connecting member 5 is inserted into the base end side of the beam-side hollow portion 41 of the beam 4. Then, the connecting member 5 and the beam 4 are fixed with three screw members 103, 103, and 104. The beam 4 and the connecting member 5 are fixed from the upper surface side of the beam 4 with two screw members 103, and the beam 4 and the connecting member 5 are fixed from the lower surface side of the beam 4 with one screw member 104. In addition, an end cap 43 is attached to the end portion on the tip side of the beam 4. In addition, the guide member 7 is attached so that the lower end opening 72 is positioned between the support column 2 and the support column cover member 3.

[0094] Next, as shown in Fig. 10, the 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 extension plate portion 42 of the beam 4 one by one in order from the end side of the base end side (the support 2 side) of the beam 4.

[0095] In detail, first, as shown in FIG. 10, the worker attaches the gutter-forming shape member 62 to the underside of the extension plate portion 42 of the beam 4 at the base end side (the support pillar 2 side) of the roof body 6. As shown in Figure 12, when installing the gutter-constituting shape member 62 on the beam 4, the worker temporarily places the gutter-constituting shape member 62 on the underside of the extension plate portion 42 of the beam 4 by hooking the hooking protrusion 624a of the gutter-constituting shape member 62 onto the hook portion 110 fixed to the underside of the extension plate portion 42 of the beam 4. This allows the worker to temporarily release his or her hands from the gutter-constituting shape member 62, allowing the work to be performed by a single worker and improving workability when attaching the gutter-constituting shape member 62 to the beam 4.

[0096] Thereafter, the worker places the gutter-constituting shape member 62 in the attachment position by rotating the gutter-constituting shape member 62 about the hooking protrusion 624a while hooking the hook portion 110 fixed to the underside of the extension plate portion 42 of the beam 4. Therefore, the gutter-constituting shape member 62 can be easily moved from the temporary placement state to the attachment position, improving the workability when attaching the gutter-constituting shape member 62 to the beam 4. Simply by hooking the hooking protrusion 624a onto the hook portion 110 and rotating it, the long shape member 61 can be placed in the attachment position to the beam 4. This improves the workability when constructing the roof body 6.

[0097] Next, the worker fixes the gutter-forming frame 62 to the extending plate portion 42 of the beam 4 with the screw members 101 and 105. Specifically, the worker moves the screw member 105 from above at the base end side of the gutter-forming frame 62, and threads the screw member 105, which has been inserted through the first gutter-forming frame mounting screw hole 421a of the extending plate portion 42 of the beam 4, into the mounting screw hole 623a of the base-end upper inward extending piece 623, thereby fixing the base end side of the gutter-forming frame 62 to the beam 4. Furthermore, the worker moves the screw member 101 from above at the tip end side of the gutter-forming frame 62, and threads the screw member 101, which has been inserted through the second gutter-forming frame mounting screw hole 421c of the extending plate portion 42 of the beam 4 and the screw hole 627a of the tip-end upper outward extending piece 627, into the nut member 601, thereby fixing the tip end side of the gutter-forming frame 62 to the beam 4. The gutter-forming shape member 62 forms the roof body side gutter forming portion 60. The roof body side gutter forming portion 60 is not visible from below the roof body 6, which improves the design.

[0098] Next, as shown in FIG. 11, the worker attaches an intermediate frame 63 to the underside of the extension plate portion 42 of the beam 4, adjacent to the tip end side of the gutter constituent frame 62 attached to the most base end side. As shown in Figure 13, when installing an intermediate extrusion 63 on a beam 4 next to the tip end of a gutter-constituting extrusion 62, a worker temporarily places the intermediate extrusion 63 below the beam 4 by hooking the return hook piece 635b of the hook extension piece 635 of the intermediate extrusion 63 onto the hook engagement portion 628a of the gutter-constituting extrusion 62 attached to the beam 4. This allows the worker to temporarily release his or her hands from the intermediate extrusion 63, allowing the work to be performed by a single worker and improving workability when attaching the gutter-constituting extrusion 62 to the beam 4.

[0099] Thereafter, with the hook extension piece 635 of the intermediate extrusion 63 hooked to the hook engagement portion 628a of the gutter constituent extrusion 62, the intermediate extrusion 63 is rotated about the return hook piece 635b (and the hook engagement portion 628a) of the hook extension piece 635, thereby arranging the intermediate extrusion 63 at the attachment position (arrangement step). This allows the intermediate extrusion 63 to be easily moved from the temporary placement state to the attachment position, improving workability when attaching the intermediate extrusion 63 to the beam 4. Furthermore, by simply hooking the return hook piece 635b to the hook engagement portion 628a and rotating it, the long extrusion 61 can be arranged at the attachment position to the beam 4. This improves workability when constructing the roof body 6.

[0100] Next, the worker fixes the intermediate extrusion 63 to the extending plate portion 42 of the beam 4 with the screw member 101. Specifically, the worker moves the screw member 101 from above at the tip end side of the intermediate extrusion 63, and threads the screw member 101, which has been passed through the one-side mounting screw hole 421d of the extending plate portion 42 of the beam 4 and the screw hole 637a of the tip end side upper outward extending piece 637, into the nut member 601, thereby fixing the tip end side of the gutter configuring extrusion 62 to the beam 4 (fixing process).

[0101] Here, the base end side of the intermediate extrusion 63 is engaged in a state in which the hook extension piece 635 of the intermediate extrusion 63 is hooked onto the hook engagement portion 628a of the gutter-forming extrusion 62, without being fixed with a screw member. Therefore, by fixing only the tip end side (one side) of the intermediate extrusion 63 with the screw member 101, the intermediate extrusion 63 can be fixed to the beam 4. Moreover, the intermediate extrusion 63 can be fixed to the beam 4 simply by moving the screw member 101 from above. This improves the workability when attaching the gutter-forming extrusion 62 to the beam 4.

[0102] Next, as shown in Figure 11, multiple intermediate extrusions 63 are attached consecutively in order from the base end side of the roof body 6 toward the tip end side, adjacent to the tip end side of the intermediate extrusions 63 attached to the beam 4. Specifically, multiple intermediate extrusions 63 are temporarily placed in order from the base end side of the roof body 6, rotated, and fixed with screw members 101, and this process is repeated. These methods are the same as when attaching intermediate extrusions 63 adjacent to the gutter-forming extrusions 62 described above, so explanations will be omitted. After attaching multiple intermediate extrusions 63 to the beam 4, a tip end extrusion 64 is attached to the tip end of the roof body 6. Then, a roof body tip cover member 65 is attached to the tip of the tip end extrusion 64.

[0103] In this way, after the long extrusions 61 are temporarily placed, they can be rotated and fixed to the beams 4 with the screw members 101, allowing a worker to easily assemble the carport 1 by himself. Furthermore, when attaching the long extrusions 61 (gutter-forming extrusions 62, intermediate extrusions 63, tip-side extrusions 64) to the beams 4, they can be attached one by one from the base end side (the support 2 side), and the long extrusions 61 can be fixed to the beams 4 simply by moving the screw members 101 from above, making the attachment work easy. This improves workability when constructing the carport 1.

[0104] Furthermore, the intermediate extrusion member 63 can be attached to the beam 4 simply by fixing one side of the intermediate extrusion member 63 in the width direction. This improves the ease of construction of the roof body 6. Furthermore, since the multiple long extrusions 61 are attached to the beams 4 in order starting from the support 2 side, the long extrusions 61 can be installed in order starting from the support 2 side, making it easy to align the long extrusions 61. Furthermore, when arranging the long extrusions 61, the long extrusions 61 can be installed in order on the side farther away from the support 2, so the support 2 is less likely to get in the way. This improves the ease of installation of the roof body 6. Furthermore, the construction method for the carport 1 of this embodiment includes a step of attaching multiple long extrusions 61 to the beams 4 in order starting from the support posts 2 side. Therefore, since the long extrusions 61 can be constructed in order starting from the support posts 2 side, it is easy to align the long extrusions 61. Furthermore, the support posts 2 are unlikely to get in the way when placing the long extrusions 61. This improves the ease of construction when constructing the roof body 6.

[0105] Next, the flow of rainwater in the carport 1 will be described. Rainwater that falls on the upper surface 6a of the roof body 6 flows along the slope of the upper surface 6a of the roof body 6 toward the support pillar 2 on the base end side, as shown in Figure 1. The water that flows toward the support pillar 2 flows into the roof body side gutter component 60, and flows into the support pillar side gutter component 20 between the support pillar 2 and the support pillar cover member 3 via the guide member 7 connected to the outlet opening 622a of the roof body side gutter component 60. The water that flows into the support pillar side gutter component 20 falls down the support pillar side gutter component 20 toward the ground 11, is received by the drainage receiving cover member 24, and is discharged outside the support pillar 2 from the discharge opening 24a located near the ground 11.

[0106] 5 and 6, a packing member 602 is disposed at the connection portion between the long members 61. Therefore, the packing member 602 can stop water flowing over the upper surface 6a of the roof body 6 at the connection portion between the long members 61. As a result, the packing member 602 stops water flowing over the upper surface 6a of the roof body 6, and water can be prevented from falling from the lower surface 6b of the roof body 6.

[0107] Furthermore, even if water passes through the packing member 602, the roof body 6 is provided with a middle gutter component 610 and a lower gutter component 620, which are arranged in two consecutive stepped stages, forming a double water stop section. Water that passes through the packing member 602 (first water stop section) flows into the lower gutter component 620 (first second water stop section). Water that overflows from the middle gutter component 610 (first second water stop section) flows into the lower gutter component 620 (second second water stop section). The two-stage gutter structure of the middle gutter component 610 and the lower gutter component 620 allows water to flow in the direction in which the connecting portions of adjacent elongated members 61 extend, i.e., along the longitudinal direction of the elongated members 61, thereby stopping the water from falling from the underside 6b of the roof body 6.

[0108] Water introduced into the middle gutter component 610 (first second water stopping portion) and the lower gutter component 620 (second second water stopping portion) flows toward the front-to-rear end portions of the roof body 6. The water that has flowed toward the front-to-rear end portions is introduced into the roof body side cover members 8.

[0109] Water introduced into the roof body side cover members 8 is received by a water receiving channel section 822 (see Figure 8) (third water stop section) formed at the lower end of the roof body side cover members 8, and is channeled along the slope of the roof body 6 toward the support column 2 on the base end side. The water channel section 822 of the roof body side cover members 8 channels the water toward the support column 2 on the base end side of the roof body 6, and falls downward from the end of the roof body 6 on the support column 2 side on the base end side. Therefore, the water receiving channel section 822 channels the water in a direction that intersects with the connecting portion of adjacent elongated members 61, thereby channeling the water toward the base end side of the roof body 6 and preventing water from falling from parts of the underside 6b of the roof body 6 other than the end.

[0110] At the same time as the water falls downward from the base end of the roof body 6 on the support column 2 side, some of the water that has been channeled toward the support column 2 in the water receiving channel section 822 flows from the base end of the roof body 6 on the support column 2 side to the drip fin 625 (see Figures 5 and 8) that protrudes downward at the lower end of the base end of the gutter-forming shape member 62 of the roof body 6, and falls downward via the drip fin 625 at the base end end of the gutter-forming shape member 62 of the roof body 6. By allowing the water to fall from the drip fin 625, it is possible to prevent the water from flowing around to the underside 6b of the roof body 6. This makes it possible to prevent water from falling from parts of the underside 6b of the roof body 6 other than the end.

[0111] Next, we will explain the fall prevention structure for the roof body 6 of the carport 1. Figure 14 is a diagram explaining the fall prevention structure for the intermediate shape members 63 in the roof body 6. Figure 15 is a diagram explaining the fall prevention structure for the gutter-forming shape members 62 in the roof body 6.

[0112] First, we will explain the fall prevention structure for the intermediate extrusions 63 in the roof body 6. In the present invention, as shown in Fig. 6, when adjacent intermediate extrusions 63 are connected, at the tip end of the intermediate extrusions 63, the hook engagement portion 638a (first hook portion 638c and second hook portion 638d) of the intermediate extrusions 63 is positioned inside the opening 639 of the adjacent intermediate extrusions 63 and is hooked and fitted into the opposing protrusions 639a (the base end side lower protrusion piece 636 and the return hook piece 635b of the L-shaped hook extension piece 635) so as to restrict movement in the up and down direction.

[0113] Therefore, at the tip end of the intermediate extrusion 63 that is fixed by the screw member 101, even if the screw member 101 that fixes the tip upper outward extension piece 637 of the intermediate extrusion 63 to the extension plate portion 42 of the beam 4 comes loose, as shown in Figure 14 (a), at the lower part of the connecting portion below the screw member 101 of the adjacent intermediate extrusion 63, the hook engagement portion 638a of the intermediate extrusion 63 is hooked onto and engaged with the opposing protrusion portion 639a of the adjacent intermediate extrusion 63, and at the upper part, the intermediate extrusions 63 abut and interfere with each other, so that the engagement between adjacent intermediate extrusions 63 is unlikely to come loose.

[0114] Furthermore, in this embodiment, even if the screw member 101 that secures the intermediate extrusion 63 comes loose in the portion of (a) in Figure 14, the intermediate extrusion 63 from which the screw member 101 has come loose is still fitted and connected on both sides with adjacent intermediate extrusions 63. As a result, the intermediate extrusion 63 from which the screw member 101 has come loose is restricted from moving downward by being fitted on both sides with the adjacent intermediate extrusions 63. Therefore, even if the screw member 101 comes loose, the roof body 6 will only bend slightly downward at the point where the screw member 101 has come loose, and the roof body 6 will be prevented from falling.

[0115] 14(b), in a state in which the hook engaging portion 638a of the intermediate extrusion 63 is caught on the return hook piece 635b of the hook extension piece 635 of the adjacent intermediate extrusion 63, the intermediate extrusion 63 from which the screw member 101 has come loose simply rotates around the return hook piece 635b of the hook extension piece 635, and does not fall, hanging from the adjacent intermediate extrusion 63. Therefore, since the intermediate extrusion 63 does not fall, it is possible to prevent the roof body 6 from falling.

[0116] Next, we will explain the fall prevention structure for the gutter-forming member 62 arranged at the end of the roof body 6 on the support pillar 2 side. When the gutter-forming member 62 is connected to the beam 4, as shown in Figure 15, the hook portion 110 is arranged below the hooking protrusion 624a of the gutter-forming member 62. Therefore, in the gutter-forming member 62 arranged closest to the support pillar 2 among the multiple long members 61 that make up the roof body 6, even if the screw members 101, 105 at both ends in the extension direction of the beam 4 come loose, as shown in Figure 15, the upper inward extending piece 624 on the tip side of the gutter-forming member 62 will hook on the rising plate 110d of the hook portion 110, and the gutter-forming member 62 will be prevented from falling. This makes it possible to prevent the roof body 6 from falling.

[0117] Next, we will explain the fall prevention structure for the tip side profile 64 arranged at the tip end of the roof body 6. Of the multiple long profiles 61 that make up the roof body 6, the tip side profile 64 (see Figure 4) that is arranged at the tip end side has both longitudinal ends of the tip side profile 64 fixed to the top cover parts 81 of the pair of roof body side cover members 8 by screw members 107, as shown in Figures 8 and 9. Therefore, even if the screw members 101 (see Figure 4) that fix the tip end of the tip side profile 64 come loose, the tip side profile 64 can be prevented from falling because it is fixed to the roof body side cover members 8 by the screw members 107 at both longitudinal ends.

[0118] The carport 1 of this embodiment described above provides the following effects. The carport 1 of this embodiment comprises pillars 2, beams 4 connected to the pillars 2, and a roof body 6 connected to the beams 4, which has a plurality of long members 61 arranged in a row in a predetermined direction and has a flat underside 6b.

[0119] Therefore, when the roof body 6 is viewed from below, the lower surface 6b is flat, which improves the design. Furthermore, because the roof body 6 is constructed by lining up multiple long members 61, it can be constructed without using a frame (frame body). This allows the thickness of the roof body 6 to be thinner than when a frame (frame body) is used, and also allows the underside 6b of the roof body 6 to be flat with no irregularities. Furthermore, since the roof body 6 is constructed by arranging a plurality of long members 61, the manufacturing cost can be reduced compared to a roof body constructed with a double structure consisting of a roof body and a ceiling material with a flat underside.

[0120] Furthermore, in the carport 1 of this embodiment, the multiple long extrusions 61 are arranged side by side in the direction in which the beams 4 extend. Therefore, the multiple long extrusions 61 can be arranged so that the longitudinal direction of the multiple long extrusions 61 extends in a direction intersecting the direction in which the beams 4 extend, and therefore the multiple long extrusions 61 can be directly fixed to the beams 4. As a result, when connecting the multiple long extrusions 61 to the beams 4, it is not necessary to connect the multiple long extrusions 61 to the beams 4 via support members or the like. Therefore, since it is not necessary to connect the beams 4 and the multiple long extrusions 61 using support members or the like, the number of parts can be reduced and construction efficiency can be improved. Furthermore, since it is not necessary to arrange support members or the like between the beams 4 and the multiple long extrusions 61, the height dimensions of the beams 4 and the roof body 6 can be reduced.

[0121] Furthermore, in the carport 1 of this embodiment, the roof body 6 is arranged below the beams 4 and suspended from the beams 4. Therefore, when the carport 1 is viewed from below, the beams 4 located above the roof body 6 are hidden by the roof body 6 and are therefore difficult to see. This improves the design of the carport 1.

[0122] Moreover, in this embodiment, the gutter-forming frame 62 has a hook engagement portion 628a, and the intermediate frame 63 attached to the beam 4 adjacent to the gutter-forming frame 62 has a return hook piece 635b that can engage with the hook engagement portion 628a and can rotate around the hook engagement portion 628a. Moreover, the intermediate frame 63 has the hook engagement portion 628a, and the intermediate frame 63 attached to the beam 4 adjacent to the intermediate frame 63 has a return hook piece 635b that can engage with the hook engagement portion 628a and can rotate around the hook engagement portion 628a. Therefore, the long frame 61 can be positioned at the attachment position to the beam 4 simply by hooking the return hook piece 635b onto the hook engagement portions 628a, 638a and rotating it. This improves the ease of construction of the roof body 6.

[0123] Furthermore, in this embodiment, the intermediate extrusion 63 has a nut member 601 that is arranged on the end side opposite the return hook piece 635b in the width direction perpendicular to the longitudinal direction and can be fixed to the beam 4 from above with a screw member 101. This allows the intermediate extrusion 63 to be attached to the beam 4 simply by fixing one end of the intermediate extrusion 63 in the width direction. This improves the ease of construction of the roof body 6. Furthermore, because the screw member 101 is fixed from above, the screw member 101 cannot be seen from below. This improves the design.

[0124] In this embodiment, the long extrusions 61 are made of hollow aluminum extrusions. By arranging them in a predetermined direction, the upper surface 6a and / or the lower surface 6b can be easily formed into a flat surface. Furthermore, since they can be easily fitted together when arranged in a predetermined direction and are easy to handle, workability can be improved. Furthermore, by forming them thin, they can be easily formed into a simple appearance, improving design. Furthermore, by constructing the multiple long extrusions 61 that make up the roof body 6 from extrusions with hollow spaces, the roof body 6 itself can be used as a strength member, eliminating the need for additional members to increase the strength of the roof body 6. Therefore, the number of parts that make up the roof body 6 can be reduced.

[0125] In this embodiment, the upper surface 6a of the roof body 6 is formed in a flat shape, which allows water to easily flow over the upper surface 6a of the roof body 6, and makes it easier to guide rainwater that falls on the upper surface 6a of the roof body 6 in a predetermined direction.

[0126] Furthermore, the construction method for the carport 1 of this embodiment includes an arrangement step in which, when attaching the intermediate extrusion 63 adjacent to the gutter-forming extrusion 62 (intermediate extrusion 63) to the beam 4, the return hook pieces 635b of the intermediate extrusion 63 are hooked onto the hook engagement portions 628a (hook engagement portions 638a) of the gutter-forming extrusion 62 (intermediate extrusion 63), and the intermediate extrusion 63 is rotated about the hook engagement portions 628a, 638a and the return hook piece 635b to arrange the intermediate extrusion 63 in the attachment position. Therefore, the intermediate extrusion 63 can be arranged in the attachment position to the beam 4 simply by hooking the return hook pieces 635b onto the hook engagement portions 628a, 638a and rotating the intermediate extrusion 63. This improves the ease of construction of the roof body 6.

[0127] Furthermore, the construction method for the carport 1 of this embodiment includes, after the placement step, a fixing step of fixing the nut member 601 of the intermediate extrusion 63 to the beam 4 from above with the screw member 101 at the end side opposite the hook piece 635b in the width direction perpendicular to the longitudinal direction. This allows the intermediate extrusion 63 to be attached to the beam 4 simply by fixing only one side of the intermediate extrusion 63 in the width direction. This improves the ease of construction of the roof body 6.

[0128] Furthermore, the construction method for the carport 1 of this embodiment includes a step of attaching multiple long extrusions 61 to the beams 4 in order starting from the support posts 2 side. Therefore, since the long extrusions 61 can be constructed in order starting from the support posts 2 side, it is easy to align the long extrusions 61. Furthermore, the support posts 2 are unlikely to get in the way when placing the long extrusions 61. This improves the ease of construction when constructing the roof body 6.

[0129] Next, a carport 1A according to a second embodiment of the present invention will be described. Figure 16 is a cross-sectional view showing the fixing structure between the support pillar 2A and the connecting member 5A, and the support pillar cover member 3A, in the carport 1A according to the second embodiment of the present invention. The carport 1A according to the second embodiment differs from the carport 1 according to the first embodiment in the direction in which the screw member 102 that fixes the support pillar 2A and the connecting member 5A is attached, and in the surface of the support pillar 2A on which the support pillar cover member 3A is arranged. In describing the second embodiment, the same components as those in the first embodiment will be assigned the same reference numerals, and their description will be omitted or simplified.

[0130] In the second embodiment, the lower end of the connecting member 5A and the upper end of the support 2A are fixed only on the inner side surface of the support 2A in the front-rear direction by four screw members 102 aligned in the vertical direction. The support pillar 2A has a pair of cover mounting walls 22A that protrude from the rear side surface toward the rear. The support column cover member 3A is attached to the pair of cover attachment 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 arranged such that the lower end opening 72A is inserted into the support-post side gutter forming portion 20A between the support post 2A and the support post cover member 3A.

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

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

[0133] The third embodiment differs from the first embodiment in that, whereas in the first embodiment an adhesive for preventing loosening is applied to the screw members 101, in the third embodiment an anti-loosening structure 66 is applied to the screw members 101A. In this embodiment, the anti-loosening structure 66 is applied to the screw members 101A that fix the gutter-forming members 62, the intermediate members 63, and the tip-end 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 fits onto the heads of the screw members 101A that fix the gutter-forming members 62, the intermediate members 63, and the tip-end member 64 to the beam 4, thereby preventing the screw members 101A from loosening.

[0134] As shown in Figures 17 and 18, the anti-loosening fitting member 67 has a plate-shaped fitting member main body 671 with a through hole 671a formed therein, a plate-shaped extension piece 672 extending laterally from the fitting member main body 671, and a locking piece 673 extending upward from the end of the extension piece 672 opposite the fitting member main 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 main body 671. When the anti-loosening fitting member 67 is fitted onto the head of the screw member 101A from above, the anti-loosening fitting uneven edge portion 671b fits into the corners of the head of the screw member 101A. As a result, the corners of the head of the screw member 101A fit into the anti-loosening fitting uneven edge portion 671b, and the anti-loosening fitting member 67 prevents the screw member 101A from loosening.

[0136] When the locking fitting member 67 is fitted onto the head of the screw member 101A, the locking piece 673 is locked into and fixed in the lower end groove 401 formed between the lower end of the hollow portion 41 of the beam 4 and the extending plate portion 42. As a result, when attaching the locking fitting member 67 to the head of the screw member 101A, by locking and fixing the locking piece 673 into the lower end groove 401 of the beam 4, the locking fitting member 67 can be fixed to the beam 4 with the locking fitting member 67 attached to the head of the screw member 101A.

[0137] The roof structure of the third embodiment described above provides the following effects. The roof structure of this embodiment is a roof structure comprising a support 2, a beam 4 connected to the support 2, and a roof body 6 connected to the beam 4, the roof body 6 having a plurality of long extrusions 61 arranged in a row in the direction in which the beam 4 extends and which are fitted together and connected to each other, and the plurality of long extrusions 61 (gutter constituent extrusions 62, intermediate extrusions 63 and tip end extrusions 64) are each fixed to the beam 4 by screw members 101A having an anti-loosening structure 66.

[0138] Therefore, the roof body 6 is fixed to the beam 4 with the screw members 101A that secure the gutter-forming members 62, the intermediate members 63, and the tip-end side members 64 secured by the locking fitting members 67, and the gutter-forming members 62, the intermediate members 63, and the tip-end side members 64 are fitted together and connected to each other. This prevents the roof body 6 from falling.

[0139] Furthermore, in this embodiment, the locking mechanism 66 has a locking fitting member 67 that is fixed to the beam 4 and fits onto the head of the screw member 101A to prevent the screw member 101A from loosening. This makes it possible to prevent the screw member 101A from loosening while it is fixed to the beam 4, with a simple structure in which the locking fitting member 67 fits onto the head of the screw member 101A.

[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 modified as appropriate. For example, in the first embodiment, the connecting member 5 was fixed to the support 2 on the side of the support 2 facing the roof body 6, and in the second embodiment, the connecting member 5A was fixed to the support 2A on the side of the support 2A on the far side. However, this is not limited to this. The connecting member 5 may also be fixed to the side of the support 2 on the near side using a screw member, or the connecting member 5 may be fixed to the side of the support 2 opposite the roof body 6. In these cases, the screw members can be covered by covering the side of the support fixed with the screw members with a support cover member.

[0141] In addition, in the above embodiment, the plurality of long members 61 are configured to be directly fixed and connected to the beam 4 by the screw members 101, 105, respectively, but this is not limiting.
