And the field edge 9 extended in the left-right direction is attached to two places before and behind the lower side of the beam 6, and the roof 3 is attached to the lower side of the field edge 9. More specifically, the field edge 9 is made of a material having a substantially rectangular cross section. As shown in FIG. 2, the upper fixture 91 is bolted to the lower surface of the beam 6. The upper fixture 91 has two drooping pieces 92 that oppose each other in the front-rear direction. The field edge 9 is sandwiched between the drooping pieces 92 and is fixed by bolting from the front and rear. Further, a substantially C-shaped attachment groove 93 is formed on the lower surface of the field edge 9, and a lower attachment tool 94 is engaged with the attachment groove 93 and attached thereto. The lower mounting tool 94 has a flat mounting surface 95 parallel to the beam 6 on the lower side, and the mounting surface 95 is brought into contact with the upper surface of the roof 3 and fixed with bolts. The roof 3 is formed by connecting a hollow flat roof member 31 extending in the front-rear direction to the left and right, and a lower fixture 94 is provided for each roof member 31. By attaching in this way, the roof 3 is oriented parallel to the beam 6, that is, it is inclined downward toward the rear side (column 1 side).

  As shown in FIG. 4, the pillar 1 includes a pillar body 10 and a pillar cover 2. The column main body 10 is made of a hollow shape, and has a shape obtained by cutting off approximately 1/3 of the front side of a substantially elliptical shape that is long in the front and rear, and a U-shaped cross section that opens toward the rear side on the front side surface. The front groove portion 11 is formed, and a rear groove portion 12 having a U-shaped cross section that opens toward the rear side is formed on the rear side surface. Moreover, the substantially rectangular and hollow protrusion part 13 is formed in the inner peripheral side of the left and right side surfaces. Furthermore, the left and right ends of the front side surface are formed with engaging portions 14 that extend toward the front side and have a tip bent toward the inner peripheral side. On the other hand, as shown in FIG. 5, the beam 6 is made of a hollow material, and three ribs 61 extending in the longitudinal direction (front-rear direction) are formed on the inner peripheral side of the left and right side surfaces. . The column main body 10 and the beam 6 configured as described above are connected by a corner member 7. As shown in FIGS. 1 and 6, the corner member 7 is an approximately L-shaped metal fitting having one arm portion 71 and the other arm portion 72 and having a substantially rectangular cross section, and the one arm portion 71 extends downward. The other arm 72 extends toward the front side. However, the other arm portion 72 is inclined downward toward the rear side. When connecting, one arm portion 71 of the corner member 7 is inserted into the upper end portion of the column main body 10, and the other arm portion 72 is inserted into the rear end portion of the beam 6. In the column main body 10, as shown in FIG. 4, the corner member 7 is positioned front, rear, left, and right by the bottom surface of the front groove portion 11, the back surface (front side surface) of the rear groove portion 12, and the inner peripheral side surfaces of the left and right protrusions 13. It is bolted from the front and rear direction. In particular, with respect to the rear bolt, a bolt hole is formed in the bottom surface of the rear groove portion 12 of the column body 10, and the head of the bolt is housed in the rear groove portion 12. The rear groove portion 12 is covered with a bolt cover. 15 is covered. As shown in FIG. 4, the bolt cover 15 is curved and forms a continuous curved surface with the outer peripheral surface of the column main body 10. As shown in FIG. 5, in the beam 6, the corner member 7 is positioned vertically and horizontally by the upper surface, the lower surface, and the left and right ribs 61 and is bolted from above and below. In addition, the notch part which opens upwards is formed in the front side surface of the upper end of the column main body 10, and the corner member 7 is formed from the front side of the column main body 10 because the other arm part 72 of the corner member 7 is accommodated in the notch part. The other arm portion 72 protrudes and the beam 6 is positioned on the front side (side) of the column main body 10. The beam 6 is fixed to the other arm portion 72 so that the rear end portion (end portion on the column 1 side) is separated from the front surface of the column main body 10.

  Further, as shown in FIG. 1, at the rear end (the column 1 side end) of the roof 3, a horizontal bar 4 extending left and right is provided. As shown in FIG. 3, the horizontal bar 4 has a substantially horizontal bottom surface portion 45, a wall surface portion 46 extending substantially vertically upward from the rear end portion of the bottom surface portion 45, and a substantially rectangular cross section formed at the front end portion of the bottom surface portion 45. The L-shaped attachment piece 43 provided on the upper surface of the hollow portion 42 is screwed to the lower surface of the roof 3, and the upper end of the wall surface portion 46 and the upper surface of the roof 3 extend back and forth. They are connected by a connecting member 44. The horizontal bar 4 is located immediately in front of the column body 10 with a slight gap from the front side surface of the column body 10. A column cover 2 is attached to the lower side portion of the horizontal bar 4 on the front side surface of the column main body 10. As shown in FIG. 7, the column cover 2 extends from a position immediately below the horizontal ridge 4 to a lower portion of the column main body 10. As shown in FIG. 4, the column cover 2 has a substantially semicircular cross section and is formed with a substantially L-shaped engaged portion 21 at both ends, and the engaged portion 21 is engaged with the column main body 10. The column main body 10 is engaged with and attached to the portion 14 to form a continuous curved surface, and the column main body 10, the column cover 2, and the bolt cover 15 are substantially elliptical symmetrical in the front-rear direction. And the vertical rod 5 extended up and down is incorporated in the pillar cover 2 (between the pillar main body 10 and the pillar cover 2). The vertical gutter 5 is made of a circular tube, and is fixed to the front side of the column main body 10 by fixing a band member 52 wound around the outer circumference of the vertical gutter 5 to an attachment base 51 screwed to the front side surface of the column main body 10. It is. As shown in FIG. 6, a cylindrical drainage 53 is inserted into the upper end of the vertical gutter 5, and the upper end of the drainage 53 is fixed to the bottom surface 45 of the horizontal gutter 4. A drainage hole 41 is opened at a connection portion of the drainage portion 53 of the bottom surface portion 45 of the horizontal rod 4 (immediately above the vertical rod 5). ing. By providing the horizontal gutter 4 and the vertical gutter 5 in this way, the rainwater accumulated on the upper surface of the roof 3 flows to the rear side (column 1 side) along the slope, flows into the horizontal gutter 4, and drains 41 and drains. It flows into the vertical gutter 5 through the part 53 and is drained. As shown in FIG. 1, the column cover 2 is also provided on the upper part of the horizontal bar 4, and has a structure in which only the part where the horizontal bar 4 is located is cut out (the upper column cover of the upper side of the horizontal bar 4 is located above. The column cover 2a is used, and the part of the column cover cut out is called the cut-out portion 2b). That is, the recumbent ridge 4 is swallowed by the cut portion 2b formed in the pillar cover. The upper column cover 2a extends from directly above the horizontal bar 4 to the upper end of the column main body 10, and has a notch that opens upward on the front side surface of the upper end. When the beam 6 is accommodated in the cutout portion, the beam 6 protrudes from the front side of the upper column cover 2a, and the rear end portion (column 1 side end portion) of the beam 6 is covered with the upper column cover 2a.

  Thus, since the vertical gutter 5 is located directly under the horizontal gutter 4, rainwater flows smoothly and it is difficult for dust to collect. Thereby, a drain elbow connecting the horizontal gutter 4 and the vertical gutter 5 is not necessary. Further, there is no drain elbow, and the vertical rod 5 is covered with the column cover 2 so that it cannot be seen from the outside. Further, the outer peripheral surfaces of the column body 10 and the column cover 2 form a continuous curved surface and become an integral shape. Therefore, the design property is good.

  Moreover, as shown in FIG.1 and FIG.5, the water stop member 8 is provided in the upper surface and side surface of the rear-end part (column 1 side edge part) of the beam 6. As shown in FIG. The water stop member 8 is made of a prismatic resin member, and is adhered and attached to the beam 6. The water stop member 8 passes through the upper surface from the lower end of one side surface perpendicular to the longitudinal direction of the beam 6. It extends to the lower end of the other side. However, the water stop member 8 attached to the upper surface and the water stop member 8 attached to the side surface are separate bodies. As described above, the rear end (column 1 side end) of the beam 6 is covered and hidden by the upper column cover 2a, and the water stop member 8 is also accommodated inside the upper column cover 2a, so that it can be seen from the outside. Therefore, the design is not impaired. And the water stop member 8 is located above the reed 4 provided in the rear end (column 1 side end) of the roof 3. By providing the water stop member 8 on the beam 6 in this way, as shown in FIG. 6, rainwater traveling along the upper surface and side surfaces of the beam 6 flows to the rear side (column 1 side) along the slope, and the water stop member It is blocked by 8 and flows down. And since the horizontal gutter 4 is located directly under the water stop member 8, the rainwater that has flowed down from the beam 6 flows into the horizontal gutter 4 and flows into the vertical gutter 5 through the drain hole 41 and the drainage portion 53 and is drained. .

  As described above, since the water stop member 8 is provided on the beam 6, rainwater traveling on the upper surface and the side surface of the beam 6 is blocked by the water stop member 8, and the beam 6 and the column main body 10 are separated from each other. The rainwater flows down in front of the column main body 10 and does not enter the column main body 10. Therefore, the corner member 7 does not get wet and corrode. And since the horizontal gutter 4 is located directly under the water stop member 8, rainwater is smoothly drained via the horizontal gutter 4 and the vertical gutter 5.

  The present invention is not limited to the above embodiment. For example, the shape and the mounting structure of the reed, the vertical reed, and the column cover may be any, and the shape and the mounting structure of the water stop member may be any. Moreover, the beam may be in contact with the side surface of the column main body. Even in this case, the rainwater is blocked by the water stop member and does not enter the inside of the column main body. Furthermore, the notch part which accommodates a corner member in the upper end part of a pillar main body may not be formed, but a beam may be supported in the position higher than the upper end of a pillar. In this case, the corner of the corner member is covered with another member. Moreover, since the roof has a structure in which roof members are continuously arranged on the left and right, the left and right lengths can be freely changed by changing the number of the roof members. As in the above embodiment, a roof with a short left-right width is used for a carport or the like, and a roof with a longer left-right width is used for a passage roof or the like. In addition, when a roof becomes long right and left, a pillar is also added suitably.
