Further, in a state where the hook extension piece 435 of the intermediate gutter constituent shape material 43 is hooked on the hook engagement portion 428a of the one-end side gutter constituent shape member 42, the intermediate gutter constituent shape material centering on the tip of the hook extension piece 435. By rotating the 43, the intermediate gutter constituent lumber 43 can be arranged at the mounting position.
In the state where the intermediate gutter constituent lumber 43 is arranged at the mounting position, the intermediate gutter is engaged with the hooking engagement portion 428a of the one end side gutter constituent lumber 42 on the other side in the left-right direction of the one end side gutter constituent lumber 42. The intermediate gutter constituent lumber 43 is attached in a state where the hooking extension piece 435 of the constituent lumber 43 is fitted.
中間樋構成形材４３の他方側上部外方延出片４３７及び他方側下部外方片４３８については、説明しない点については、一端部側樋構成形材４２の他方側上部外方延出片４２７及び他方側下部外方片４２８の構造と同様である。そのため、中間樋構成形材４３の他方側上部外方延出片４３７及び他方側下部外方片４３８の構造については、図７において一端部側樋構成形材４２の構造に対応する符号を付して、その説明を省略する。
Regarding the other side upper outer extension piece 437 and the other side lower outer outer piece 438 of the intermediate gutter constituent lumber 43, the other side upper outer extension piece of the one end side gutter constituent lumber 42 is not explained. It is similar to the structure of 427 and the lower outer piece 428 on the other side. Therefore, the structures of the other side upper outer extension piece 437 and the other side lower outer outer piece 438 of the intermediate gutter constituent lumber 43 are designated with reference numerals corresponding to the structure of the one end side gutter constituent lumber 42 in FIG. Therefore, the description thereof will be omitted.
また、連続して配置される複数の中間樋構成形材４３の構成は全て同様の構成であるため、その説明を省略する。梁３に接続した中間樋構成形材４３の隣りに、隣接する中間樋構成形材４３を取り付ける場合には、一端部側樋構成形材４２の隣りに中間樋構成形材４３を取り付ける場合と同様に、梁３の延出板部３２に接続された中間樋構成形材４３の引っ掛け係合部４３８ａに、中間樋構成形材４３の引っ掛け延出片４３５を引っ掛けることで、梁３の下方において、中間樋構成形材４３を仮置きできる。また、中間樋構成形材４３の引っ掛け係合部４３８ａに中間樋構成形材４３の引っ掛け延出片４３５を引っ掛けた状態で、引っ掛け延出片４３５を中心に中間樋構成形材４３を回転することで、中間樋構成形材４３を取り付け位置に配置できる。隣接する中間樋構成形材４３を取り付け位置に配置した状態においては、中間樋構成形材４３における左右方向の他方側には、中間樋構成形材４３の引っ掛け係合部４３８ａに、隣接する中間樋構成形材４３の引っ掛け延出片４３５が嵌合した状態で、隣接する中間樋構成形材４３が取り付けられる。
Further, since the configurations of the plurality of intermediate gutter constituent shaped members 43 that are continuously arranged are all the same, the description thereof will be omitted. When the adjacent intermediate gutter constituent lumber 43 is attached next to the intermediate gutter constituent lumber 43 connected to the beam 3, the intermediate gutter constituent lumber 43 is attached next to the one end side gutter constituent lumber 42. Similarly, by hooking the hook extension piece 435 of the intermediate gutter constituent lumber 43 to the hook engagement portion 438a of the intermediate gutter constituent lumber 43 connected to the extension plate portion 32 of the beam 3, the lower part of the beam 3 is hooked. In, the intermediate gutter constituent lumber 43 can be temporarily placed. Further, in a state where the hook extension piece 435 of the intermediate gutter constituent shape member 43 is hooked on the hook engagement portion 438a of the intermediate gutter constituent shape member 43, the intermediate gutter constituent shape member 43 is rotated around the hook extension piece 435. As a result, the intermediate gutter constituent lumber 43 can be arranged at the mounting position. In the state where the adjacent intermediate gutter constituent lumber 43 is arranged at the mounting position, the intermediate gutter constituent lumber 43 is adjacent to the hook engaging portion 438a of the intermediate gutter constituent lumber 43 on the other side in the left-right direction. The adjacent intermediate gutter constituent lumber 43 is attached in a state where the hooking extension piece 435 of the gutter constituent lumber 43 is fitted.
屋根体４の左右方向の他方側の端部に配置される他端部側樋構成形材４４は、一方側の端部の構成が、中間樋構成形材４３の一方側の端部の構成と同様であり、一方側の端部以外の構成が、他方側の端部に配置される一端部側樋構成形材４２を左右反転した構成と同様である。そのため、屋根体４の左右方向の他方側の端部に配置される他端部側樋構成形材４４の説明を省略する。
The other end side gutter constituent shape member 44 arranged at the other end of the roof body 4 in the left-right direction has a structure of one end of the structure of one end of the intermediate gutter structure member 43. The same is true for the configuration other than the one-sided end portion, which is the same as the configuration in which the one-end side gutter constituent shape member 42 arranged at the other-side end portion is horizontally inverted. Therefore, the description of the other end side gutter constituent shape member 44 arranged at the other end of the roof body 4 in the left-right direction will be omitted.
以上のように構成される屋根体４は、図５～図７に示すように、アルミ材料の押出し形材で形成された複数の長尺形材４１を連結して屋根体４を構成することで、複数の長尺形材４１を、屋根体４の面材として使用できると共に、屋根体４の強度を確保することができる。また、屋根体４を構成する複数の長尺形材４１を、複数の凹状の屋根体側樋構造４０により水を流すように構成すると共に、中間樋構成形材４３に中間ホロー部４３１を形成することで、屋根体４自体を強度部材として使用できる。これにより、屋根体４の強度を出すための部材を別に設ける必要がない。よって、屋根体４を構成する部材の部品点数を低減できる。また、中間樋構成形材４３の中間ホロー部４３１の一方側の面にビード材取付凹部４３３を設けたため、ビード材４０１を取り付ける部分の強度を確保できる。
As shown in FIGS. 5 to 7, the roof body 4 configured as described above is formed by connecting a plurality of long profile members 41 formed of extruded aluminum material to form the roof body 4. Therefore, a plurality of long shaped members 41 can be used as a face material of the roof body 4, and the strength of the roof body 4 can be ensured. Further, the plurality of long shaped members 41 constituting the roof body 4 are configured to allow water to flow through the plurality of concave roof body side gutter structures 40, and the intermediate hollow portion 431 is formed in the intermediate gutter constituent shaped members 43. Therefore, the roof body 4 itself can be used as a strength member. As a result, it is not necessary to separately provide a member for increasing the strength of the roof body 4. Therefore, the number of parts of the members constituting the roof body 4 can be reduced. Further, since the bead material mounting recess 433 is provided on one surface of the intermediate hollow portion 431 of the intermediate gutter constituent profile 43, the strength of the portion to which the bead material 401 is mounted can be secured.
また、屋根体端部側樋構造４０ａ，４０ｃ及び屋根体中間樋構造４０ｂは、上部側が開口して屋根体４の複数の凹状の屋根体側樋構造４０を構成しているため、屋根体４の下方から見た場合に、長尺形材４１のフラットな（平面状の）下面４ｂが見えるだけで、屋根体４の上面４ａ側に樋が存在することを認識させずに樋を構成できる。そのため、意匠性を向上できる。
Further, since the roof body end side gutter structures 40a and 40c and the roof body intermediate gutter structure 40b have a plurality of concave roof body side gutter structures 40 having an opening on the upper side, the roof body 4 has a plurality of concave roof body side gutter structures 40. When viewed from below, the gutter can be configured without recognizing the existence of the gutter on the upper surface 4a side of the roof body 4 only by seeing the flat (planar) lower surface 4b of the long profile 41. Therefore, the design can be improved.
屋根体上流側端部カバー部材８は、図１に示すように、屋根体４の前後方向の上流側の端部において、屋根体４の左右方向（長尺形材４１の長手方向に直交（交差）する方向）に延びて配置される。屋根体上流側端部カバー部材８は、屋根体４の前後方向の上流側の端部において、長尺形材４１の上流側の側部（端部）を覆うように配置される。
As shown in FIG. 1, the roof body upstream end cover member 8 is orthogonal to the left-right direction of the roof body 4 (longitudinal direction of the long profile 41) at the upstream end of the roof body 4 in the front-rear direction. It is arranged so as to extend in the direction of crossing). The roof body upstream side end cover member 8 is arranged so as to cover the upstream side portion (end portion) of the long profile 41 at the upstream end portion of the roof body 4 in the front-rear direction.
複数の屋根体下流側端部カバー部材９は、図８～図１０に示すように、屋根体４における傾斜方向の下流側（前後方向の前側）の端部に配置されている。複数の屋根体下流側端部カバー部材９は、それぞれ、左右方向に離間して配置される中間樋構成形材４３の中間ホロー部４３１の下流側の端面を覆うように配置される。これにより、屋根体４を構成する複数の長尺形材４１の前側の端部において、中間樋構成形材４３における中間ホロー部４３１の開口した端面が外部に露出されない。
As shown in FIGS. 8 to 10, the plurality of roof body downstream end cover members 9 are arranged at the downstream end (front side in the front-rear direction) of the roof body 4 in the inclined direction. The plurality of roof body downstream end cover members 9 are arranged so as to cover the downstream end faces of the intermediate hollow portion 431 of the intermediate gutter constituent profile 43, which are arranged apart from each other in the left-right direction. As a result, at the front end portions of the plurality of long shaped members 41 constituting the roof body 4, the open end faces of the intermediate hollow portions 431 of the intermediate gutter constituent shaped members 43 are not exposed to the outside.
また、複数の屋根体下流側端部カバー部材９は、図９に示すように、それぞれ、上流側から下流側に向かうに従って下るように傾斜する遮蔽傾斜板９１と、遮蔽傾斜板９１の下端部と長尺形材４１の下端部との間に形成される下方開口部９２と、を有する。
Further, as shown in FIG. 9, the plurality of roof body downstream end cover members 9 have a shielding inclined plate 91 that inclines downward from the upstream side toward the downstream side, and a lower end portion of the shielding inclined plate 91, respectively. It has a lower opening 92 formed between the and the lower end portion of the long profile 41.
下方開口部９２は、屋根体下流側端部カバー部材９の下端部において、下方を向いて形成される。下方開口部９２からは、長尺形材４１の内部を流通する水が下方に向けて排出される。複数の屋根体下流側端部カバー部材９の下方開口部９２の下方には、屋根体下流側樋構造４５（後述）が配置される。複数の屋根体下流側端部カバー部材９は、下方に向けて開口するため、中間樋構成形材４３の中間ホロー部４３１の内部を流れる水は、屋根体下流側樋構造４５に流入する。
The lower opening 92 is formed at the lower end of the roof body downstream end cover member 9 so as to face downward. From the lower opening 92, water flowing inside the long profile 41 is discharged downward. A roof gutter structure 45 (described later) is arranged below the lower opening 92 of the plurality of roof body downstream end cover members 9. Since the plurality of roof body downstream end cover members 9 open downward, water flowing inside the intermediate hollow portion 431 of the intermediate gutter constituent profile 43 flows into the roof body downstream side gutter structure 45.
また、複数の屋根体下流側端部カバー部材９において、遮蔽傾斜板９１の上端部が屋根体４の内側に位置し、かつ、遮蔽傾斜板９１は、上流側から下流側に向かうに従って下るように傾斜するため、屋根体４の他方側の端部側の下方の地面１１側からは視認しにくい形状である。よって、屋根体４の意匠性を向上できる。
Further, in the plurality of roof body downstream end cover members 9, the upper end of the shielding inclined plate 91 is located inside the roof body 4, and the shielding inclined plate 91 descends from the upstream side to the downstream side. The shape is difficult to see from the ground 11 side below the end side of the other side of the roof body 4 because it is inclined to. Therefore, the design of the roof body 4 can be improved.
屋根体下流側樋構造４５は、屋根体４を構成する複数の長尺形材４１の下流側（前後方向の前側）の端部の下方に配置され、複数の長尺形材４１の下流側端部の下部に固定される。屋根体下流側樋構造４５は、上方が開放した樋形状に形成され、屋根体４の左右方向の全域に亘って延びる。

The roof body downstream side gutter structure 45 has a downstream gutter body 451 with an open upper part and an upstream side inward extending substantially horizontally from the upper end of the upstream side of the downstream gutter body 451 to the inside of the downstream gutter body 451. The extension piece 452, the upstream lower bending piece 453 formed on the upstream side of the lower end portion on the upstream side of the downstream side gutter main body 451 and the downstream side gutter main body 451 from the downstream upper end portion of the downstream gutter main body 451. It has a downstream side inward extending piece 454 extending inward substantially horizontally, and a downstream side upward protruding piece 455 protruding upward from the downstream upper end portion of the downstream side gutter body.
屋根体下流側樋構造４５の上流側内方延出片４５２の上面には、複数の長尺形材４１の下流側の端部の下面が配置され、屋根体下流側樋構造４５の上流側内方延出片４５２は、図８及び図１０に示すように、複数の長尺形材４１の下流側の端部において、ネジ部材１０６により、複数の長尺形材４１の下面に固定される。屋根体下流側樋構造４５の上流側内方延出片４５２及び複数の長尺形材４１の下流側の端部は、図８に示すように、屋根体側樋構造４０の上方から移動されるネジ部材１０６により、共締めされて固定される。
On the upper surface of the upstream inward extension piece 452 of the roof structure downstream side gutter structure 45, the lower surface of the downstream end portion of the plurality of long profiles 41 is arranged, and the lower surface of the downstream end of the roof body downstream side gutter structure 45 is arranged on the upstream side of the roof body downstream side gutter structure 45.

To. The downstream end of the upstream inward extension piece 452 of the roof downstream gutter structure 45 and the plurality of long lumber 41s are moved from above the roof gutter structure 40 as shown in FIG. It is fastened and fixed together by the screw member 106.
ここで、図１０に示すように、屋根体４の長尺形材４１にネジ部材１０６が貫通するネジ孔４０２が形成されても、ネジ孔４０２の下方には、屋根体下流側樋構造４５が配置される。そのため、ネジ孔４０２からの水は、屋根体下流側樋構造４５に落下されて、屋根体下流側樋構造４５に受け止められる。これにより、屋根体４の下方への水の落下を抑制した状態で、屋根体下流側樋構造４５を屋根体４に取り付けることができる。
Here, as shown in FIG. 10, even if a screw hole 402 through which the screw member 106 penetrates is formed in the long profile 41 of the roof body 4, the roof structure downstream side gutter structure 45 is below the screw hole 402. Is placed. Therefore, the water from the screw hole 402 is dropped on the roof body downstream side gutter structure 45 and is received by the roof body downstream side gutter structure 45. As a result, the roof gutter structure 45 on the downstream side of the roof can be attached to the roof 4 in a state where the water does not fall downward from the roof 4.
屋根体下流側樋構造４５には、屋根体４の上面４ａに形成された凹状の複数の屋根体側樋構造４０を流れた水と、屋根体４を構成する複数の長尺形材４１の内部から排出された水とが流入する。屋根体下流側樋構造４５の左右方向の両端部の下面には、図８に示すように、排出用開口４５ａが形成される。

次に、本実施形態のカーポート１における雨水の流れについて説明する。
図１に示すカーポート１において、屋根体４の上面４ａに降り注いだ雨水は、上面４ａに形成される長尺形材４１の長尺方向に延びる凹状の複数の屋根体側樋構造４０に沿って、屋根体４の傾斜方向の上流側から下流側（前後方向の後側から前側）に流れる。
Next, the flow of rainwater in the carport 1 of the present embodiment will be described.
In the carport 1 shown in FIG. 1, the rainwater that has fallen on the upper surface 4a of the roof body 4 is formed along the plurality of concave roof gutter structures 40 extending in the elongated direction of the long profile 41 formed on the upper surface 4a. , Flows from the upstream side to the downstream side (from the rear side to the front side in the front-rear direction) of the roof body 4 in the inclined direction.
屋根体４の上面４ａを前後方向の前側の下流側に流れる水は、屋根体４の上面４ａに形成される凹状の複数の屋根体側樋構造４０を通って、屋根体４の上面４ａの傾斜方向の下流側に流れて、梁３の下方を通過して、屋根体下流側樋構造４５に到達する。これにより、屋根体４を流通する水や水に流される汚れ（例えば、落ち葉など）を梁３の下方において複数の凹状の屋根体側樋構造４０に通過させて、屋根体４の傾斜方向において、水や水に流される汚れを、上流側から下流側に向けて流すことができる。これにより、排水性能を向上できる。
The water flowing from the upper surface 4a of the roof body 4 to the front downstream side in the front-rear direction passes through a plurality of concave roof side gutter structures 40 formed on the upper surface 4a of the roof body 4 and is inclined to the upper surface 4a of the roof body 4. It flows to the downstream side in the direction, passes under the beam 3, and reaches the roof body downstream side gutter structure 45. As a result, the water flowing through the roof body 4 and dirt flowing through the water (for example, fallen leaves) are passed through the plurality of concave roof body side gutter structures 40 below the beam 3, and the roof body 4 is inclined in the inclined direction. Water and dirt that is washed away by water can be washed away from the upstream side to the downstream side. This can improve the drainage performance.
長尺形材４１の内部において、中段樋構成部４１０と下段樋構成部４２０とに導入された水は、屋根体４の前後方向の下流側の端部に向けて流れる。前後方向の下流側の端部に向けて流れた水は、下流側の端部において、複数の屋根体下流側端部カバー部材９の下部の下方開口部９２から、屋根体下流側樋構造４５に排出される。
Inside the long profile 41, the water introduced into the middle gutter component 410 and the lower gutter component 420 flows toward the downstream end of the roof body 4 in the front-rear direction. The water flowing toward the downstream end in the front-rear direction flows from the lower opening 92 at the lower part of the plurality of roof body downstream end cover members 9 to the roof downstream gutter structure 45 at the downstream end. Is discharged to.
屋根体下流側樋構造４５には、屋根体４の上面４ａを流れた水と、屋根体４を構成する複数の長尺形材４１の内部の樋構成部（中段樋構成部４１０及び下段樋構成部４２０）から排出された水と、が流入する。屋根体下流側樋構造４５の左右方向の一方側の端部の下面には、排出用開口４５ａ（図８参照）が形成される。
In the roof gutter structure 45 on the downstream side of the roof, the water flowing through the upper surface 4a of the roof 4 and the internal gutter components (middle gutter component 410 and lower gutter) of the plurality of long shaped members 41 constituting the roof 4 are formed. The water discharged from the component part 420) flows in. A discharge opening 45a (see FIG. 8) is formed on the lower surface of one end of the roof structure 45 on the downstream side in the left-right direction.
屋根体下流側樋構造４５に流入した水は、屋根体４の左右方向の両端部側に形成される排出用開口４５ａを介して、屋根体４における長尺形材４１が並ぶ方向の端部側において、屋根体４の下方に配置される下方側傾斜樋構造４６を介して、支柱２の内部に設けられた支柱側樋構成部２０（図５参照）に誘導される。支柱側樋構成部２０に流入した水は、支柱側樋構成部２０を落下して、支柱２の下方において、支柱２の外部に排出される。
The water that has flowed into the gutter structure 45 on the downstream side of the roof body passes through the discharge openings 45a formed on both ends in the left-right direction of the roof body 4, and is the end portion of the roof body 4 in the direction in which the long shaped members 41 are lined up. On the side, it is guided to the column side gutter component 20 (see FIG. 5) provided inside the column 2 via the downward inclined gutter structure 46 arranged below the roof body 4. The water that has flowed into the column-side gutter component 20 falls down the column-side gutter component 20 and is discharged to the outside of the column 2 below the column 2.
以上のように構成される屋根構造体において、屋根体４の上面４ａには、複数の凹状の屋根体側樋構造４０が形成される。そのため、屋根体４の上面４ａを流通する水は、梁３よりも下方を通過して、屋根体４の傾斜方向の下流側（前後方向の前側）に向かって流れる。そのため、排水性能を向上できる。
In the roof structure configured as described above, a plurality of concave roof body side gutter structures 40 are formed on the upper surface 4a of the roof body 4. Therefore, the water flowing through the upper surface 4a of the roof body 4 passes below the beam 3 and flows toward the downstream side (front side in the front-rear direction) of the roof body 4 in the inclined direction. Therefore, the drainage performance can be improved.
また、屋根体４の上面４ａには、複数の凹状の屋根体側樋構造４０が設けられるため、梁３と屋根体４との間に吊り具などを介在させずに、梁３を屋根体４に直接接続できる。そのため、梁３と屋根体４とを密着させて配置することができる。これにより、屋根体４の上方の低い位置に梁３を設置できるため、下方から見た場合に梁３が大きく上方側に突出しておらず、屋根体４を含んだ屋根構造の厚さを薄く見せることができ、屋根構造をコンパクトに形成できる。よって、スマートなカーポート１を実現でき、意匠性を向上できる。
Further, since a plurality of concave roof body side gutter structures 40 are provided on the upper surface 4a of the roof body 4, the beam 3 can be mounted on the roof body 4 without interposing a hanging tool or the like between the beam 3 and the roof body 4. Can be connected directly to. Therefore, the beam 3 and the roof body 4 can be arranged in close contact with each other. As a result, the beam 3 can be installed at a low position above the roof body 4, so that the beam 3 does not greatly protrude upward when viewed from below, and the thickness of the roof structure including the roof body 4 is reduced. It can be shown and the roof structure can be formed compactly. Therefore, a smart carport 1 can be realized and the design can be improved.
また、複数の長尺形材４１が並んで連設されることで屋根体４を構成しており、屋根体４の下面４ｂが平面状に形成されるため、屋根体４を下方から見た場合の意匠性を向上できる。
Further, since the roof body 4 is formed by arranging a plurality of long shaped members 41 side by side and the lower surface 4b of the roof body 4 is formed in a flat shape, the roof body 4 is viewed from below. The design of the case can be improved.
以上説明した本実施形態のカーポート１によれば、以下のような効果を奏する。
本実施形態のカーポート１は、支柱２と、支柱２に接続される梁３と、梁３に直接的に又は間接的に接続される屋根体４であって、所定方向に並んで連設される複数の長尺形材４１を有する屋根体４と、を備え、屋根体４は、下面４ｂが平面状に形成され、上面４ａの少なくとも一部に凹状の複数の屋根体側樋構造４０を有する。そのため、梁３と屋根体４の複数の凹状の屋根体側樋構造４０を備えるため、屋根体４を流通する水や水に流される汚れ（例えば、落ち葉など）を複数の凹状の複数の屋根体側樋構造４０に通過させて、屋根体４の傾斜方向の下流側に向けて流すことができる。これにより、排水性能を向上できる。また、屋根体４の下面４ｂが平面状に形成されることから、意匠性を向上できる。
According to the carport 1 of the present embodiment described above, the following effects are obtained.
The carport 1 of the present embodiment is a support column 2, a beam 3 connected to the support column 2, and a roof body 4 directly or indirectly connected to the beam 3, and is continuously arranged side by side in a predetermined direction. The roof body 4 includes a roof body 4 having a plurality of long shaped members 41 to be formed, and the roof body 4 has a plurality of concave roof body side gutter structures 40 having a lower surface 4b formed in a flat shape and at least a part of the upper surface 4a. Have. Therefore, since the beam 3 and the roof body 4 are provided with the plurality of concave roof body side gutter structures 40, the water flowing through the roof body 4 and the dirt (for example, fallen leaves) washed away by the water are removed from the plurality of concave roof body sides. It can be passed through the gutter structure 40 and flowed toward the downstream side in the inclined direction of the roof body 4. This can improve the drainage performance. Further, since the lower surface 4b of the roof body 4 is formed in a flat shape, the design can be improved.
また、本実施形態においては、屋根体４は、凹状の屋根体側樋構造４０を有する長尺形材４１を複数含んで構成されている。これにより、複数の長尺形材４１を連設するだけで、屋根体４の上面４ａに複数の屋根体側樋構造４０を形成できる。よって、簡易な構成で、排水性能を向上できる。
Further, in the present embodiment, the roof body 4 is configured to include a plurality of long lumbers 41 having a concave roof body side gutter structure 40. As a result, a plurality of roof body side gutter structures 40 can be formed on the upper surface 4a of the roof body 4 only by connecting the plurality of long shaped members 41 in succession. Therefore, the drainage performance can be improved with a simple configuration.
また、本実施形態においては、複数の中間樋構成形材４３が連結される部分では、屋根体４は、凹状の屋根体側樋構造４０と中空部が形成されたホロー構造とを有する中間樋構成形材４３を複数含んで構成されている。これにより、屋根体４の中間樋構成形材４３においては、屋根体側樋構造４０により水の流通を確保しつつ、ホロー構造により屋根体４の強度を確保できる。また、中間樋構成形材４３は、ホロー構造を有するため、形材として強度を有する。そのため、複数の中間樋構成形材４３を連結する際の施工性が良好であり、屋根体４を施工する際の施工性を向上できる。
Further, in the present embodiment, in the portion where the plurality of intermediate gutter constituent members 43 are connected, the roof body 4 has an intermediate gutter structure having a concave roof body side gutter structure 40 and a hollow structure in which a hollow portion is formed. It is configured to include a plurality of shape members 43. As a result, in the intermediate gutter constituent profile 43 of the roof body 4, the strength of the roof body 4 can be ensured by the hollow structure while ensuring the flow of water by the roof body side gutter structure 40. Further, since the intermediate gutter constituent lumber 43 has a hollow structure, it has strength as a lumber. Therefore, the workability when connecting the plurality of intermediate gutter constituent lumbers 43 is good, and the workability when constructing the roof body 4 can be improved.
また、本実施形態においては、屋根体４の上面４ａには、梁３に直接的に接続される部分（一端部側樋構成形材４２の一方側上部内方延出片４２３及び他方側上部外方延出片４２７，中間樋構成形材４３の他方側上部外方延出片４３７、他端部側樋構成形材４４の他方側上部内方延出片４４３）が設けられ、屋根体４は、梁３の下方において梁３に直接的に吊られて配置される。そのため、梁３と屋根体４とを密着させて配置することができる。これにより、屋根体４の上方の低い位置に梁３を設置できるため、下方から見た場合に梁３が大きく上方側に突出しておらず、屋根体４を含んだ屋根構造の厚さを薄く見せることができ、屋根構造をコンパクトに形成できる。よって、スマートなカーポート１を実現でき、より意匠性を向上できる。
Further, in the present embodiment, the upper surface 4a of the roof body 4 has a portion directly connected to the beam 3 (one side upper inward extending piece 423 and the other side upper part of the one-sided side gutter constituent shape member 42). The outer extension piece 427, the other side upper outer extension piece 437 of the intermediate gutter constituent profile 43, and the other side upper upper inner extension piece 443 of the other end side gutter constituent profile 44) are provided, and the roof body is provided. 4 is arranged so as to be directly suspended from the beam 3 below the beam 3. Therefore, the beam 3 and the roof body 4 can be arranged in close contact with each other. As a result, the beam 3 can be installed at a low position above the roof body 4, so that the beam 3 does not greatly protrude upward when viewed from below, and the thickness of the roof structure including the roof body 4 is reduced. It can be shown and the roof structure can be formed compactly. Therefore, a smart carport 1 can be realized and the design can be further improved.
また、本実施形態においては、屋根体４は、長尺形材４１の長手方向の一方側から他方側に向かうに従って下るように傾斜する。そのため、屋根体４は、複数の凹状の複数の屋根体側樋構造４０が延びる方向に傾斜する。これにより、屋根体４を流通する水や水に流される汚れ（例えば、落ち葉など）を、複数の凹状の複数の屋根体側樋構造４０を通過させて屋根体４の下流側に誘導しやすい。よって、排水性能を一層向上できる。
Further, in the present embodiment, the roof body 4 is inclined so as to descend from one side in the longitudinal direction of the long profile 41 toward the other side. Therefore, the roof body 4 is inclined in the direction in which the plurality of concave roof body side gutter structures 40 extend. As a result, the water flowing through the roof body 4 and dirt flowing through the water (for example, fallen leaves) can easily be guided to the downstream side of the roof body 4 by passing through the plurality of concave roof body side gutter structures 40. Therefore, the drainage performance can be further improved.
また、本実施形態においては、長尺形材４１は、アルミ材料の形材で形成され、少なくとも一部に中空部を有するホロー構造を備える。これにより、中空部を有するホロー構造の部分により、屋根体４の強度を確保できる。
Further, in the present embodiment, the long profile 41 is formed of a profile made of an aluminum material, and has a hollow structure having a hollow portion at least partially. As a result, the strength of the roof body 4 can be ensured by the portion of the hollow structure having the hollow portion.
