Hereinafter, preferred embodiments of the outdoor structure according to the present invention will be described in detail with reference to the accompanying drawings.

1 to 6 show an outdoor structure according to an embodiment of the present invention. The outdoor structure illustrated here is a balcony provided so that the deck portion 10 projects from the outer wall surface W of the upper floor of the building. In the following, for convenience, the direction in which the balcony is separated from the outer wall surface W of the building is referred to as the front, and the direction in which the balcony is close to the building is referred to as the rear.

The deck portion 10 is provided with end beams (cross members) 12 on both sides of a skeleton attachment member 11 attached to the outer wall surface W of the building, and is provided with joists (cross members) 13 at a portion between the end beams 12. , The projecting ends of the end beam 12 and the joist 13 are connected to each other by the front girder (cross member) 14. A plurality of base materials 20 and a plurality of deck materials 30 are arranged side by side in the rectangular region 15 surrounded by the end beam 12, the joist 13, and the front girder 14.

The end beam 12, the joist 13, and the front girder 14 are extruded lumbers formed of a metal such as an aluminum alloy, and are arranged so as to be substantially horizontal. In the present embodiment, the end beam 12, the joist 13, and the front girder 14 which are hollow and have a vertically long rectangular shape and are formed in a square cylinder shape are applied. The inner side surface 14a of the front girder 14 facing the rectangular region 15 is provided with a girder gutter 16 along the length of the front girder 14, and the inner side surfaces 12a and 13a of the end beam 12 and the joist 13 facing the rectangular region 15 are provided. A beam gutter 17 is provided along the lengths of the end beam 12 and the joist 13, respectively.

The gutter 16 is integrally molded with the front gutter 14, and has an inner horizontal plate portion 16a and an inner bent portion 16b. The inner horizontal plate portion 16a is a flat plate-like portion extending substantially horizontally from the inner side surface 14a of the front girder 14 toward the rectangular region 15. The extending edge portion of the inner horizontal plate portion 16a is slightly bent upward. The inner bent portion 16b is a flat plate-shaped portion that protrudes upward from the intermediate portion of the inner horizontal plate portion 16a, and constitutes a gutter portion 16c that opens upward between the inner side surface 14a of the front girder 14. .. The upper end edge of the inner bent portion 16b is set to be lower than the upper end surface of the front girder 14. Both ends of the gutter 16 are open, and the received water can be discharged from both ends.

The beam gutter 17 is configured by attaching a separate gutter member 17A to the inner side surface 12a of the end beam 12 and the inner side surface 13a of the joist 13, and the length of the end beam 12 and the joist 13 below the gutter 16. It extends almost horizontally along. The gutter member 17A is composed of a flat bottom wall plate 17Aa and a side wall plate 17Ab extending upward from both sides of the bottom wall plate 17Aa, via one side wall plate 17Ab. It is attached to the gutter beam 12 and the joist 13. Each beam gutter 17 is closed at both ends, while a drain gutter 18 is connected to the lower surface of each front end portion, and drainage is possible through the drain gutter 18.

The base material 20 is an extruded shape material formed of a metal such as an aluminum alloy. In the present embodiment, the base material 20 is composed of the base main body 21 and the horizontal plate portions 22 and 23 provided on both side edges of the base main body 21. The base body portion 21 has a rectangular tubular shape having a substantially horizontally long rectangular cross section, and has a fastening gutter portion 21a at the center. The fastening gutter portion 21a is a concave groove portion having a rectangular cross section with an open upper surface. The horizontal plate portions 22 and 23 are flat plate-shaped portions extending substantially horizontally from the base main body portion 21, one edge portion of the base main body portion 21 extending from the upper corner portion, and the other edge portion. Extends from the lower corner. Bending portions 24 and 25 are provided on the individual horizontal plate portions 22 and 23. The bent portions 24 and 25 are flat plate-shaped portions extending along the upper and lower sides. The horizontal plate portion (hereinafter referred to as the upper horizontal plate portion 22) provided in the upper corner portion of the base body portion 21 is provided with a bent portion 24 downward from the extending edge portion thereof, and is provided in the lower corner portion. The horizontal plate portion (hereinafter referred to as the lower horizontal plate portion 23) is provided with a bent portion 25 upward from the extending edge portion thereof.

The base material 20 having the above-described configuration is arranged along the front girder 14 with the upper horizontal plate portion 22 facing forward, and both left and right ends are provided on the upper surface and the joist 13 of the beam gutter 17 provided on the end beam 12. A plurality of beams are arranged side by side in the front and rear while being placed on the upper surface of the provided beam gutter 17. The beam gutter 17 is fixed by fastening the screw S via the fastening gutter portion 21a, respectively. The intermediate portion of the base material 20 may be fixed to the bracket 1 provided between the front girder 14 and the skeleton mounting member 11 with screws S. As is clear from the figure, in the base materials 20 adjacent to each other, the bent portion 24 provided on the upper horizontal plate portion 22 faces the lower horizontal plate portion 23, and the bent portion 25 provided on the lower horizontal plate portion 23 is formed. They are arranged side by side so as to face the upper horizontal plate portion 22. That is, between the adjacent base materials 20, the upper horizontal plate portion 22 and the lower horizontal plate portion 23 overlap each other in the vertical direction, and no gap is generated along the vertical direction. Moreover, in the lower horizontal plate portion 23, since the bent portion 25 extends upward from the extending edge portion, it has a function of a gutter, and water drops between the adjacent base materials 20. If so, it can be reliably received on the upper surface of the water without leaking downward.

The deck material 30 is a plate-shaped member that serves as a floor surface of the balcony. In the present embodiment, the floor surface of the balcony is formed by arranging a plurality of deck members 30 having a hollow plate shape formed of a resin containing wood powder in a posture along the beam 12. Each deck material 30 is attached to the base material 20 by a connecting metal fitting 40 provided on the base material 20. In the present embodiment, the deck material 30 is arranged in a slightly inclined state so as to be slightly downward toward the front.

Here, the above-mentioned base material 20 and deck material 30 are arranged on the deck portion 10 with reference to the skeleton mounting member 11. Therefore, with respect to the base material 20, a gap may occur between the gutter 16 of the front gutter 14 and the upper horizontal plate portion 22 of the base material 20, and with respect to the deck material 30, although they are adjacent to each other, the edge end surface 30a may occur. Can be uneven with each other. Therefore, in the present embodiment, the above-mentioned problem is solved by interposing the attachment 50 along the front girder 14 between the gutter 16 of the front girder 14 and the base material 20 and the deck material 30 in the deck portion 10. I am trying to do it.

The attachment 50 is an extruded shape material formed of a metal such as an aluminum alloy. In the present embodiment, an attachment 50 having a flat plate-shaped main body 51 extending along the upper and lower sides and having auxiliary horizontal plate portions 52 and 53 on both side edges of the main body 51 is applied. There is. The main body 51 is set so that when the lower end is placed on the upper surface of the beam gutter 17, the upper end protrudes slightly upward from the upper surface 30b of the deck material 30. The main body 51 is provided with a cover portion 54 at the upper end edge and a gutter contact portion 55 at an intermediate portion. The cover portion 54 is bent and extends at a substantially right angle from the upper end edge of the main body portion 51 toward the rear. The gutter contact portion 55 is a portion that extends substantially horizontally from the front surface of the main body 51 toward the front and then bends upward at a substantially right angle and extends. The gutter contact portion 55 hits the inner bent portion 16b of the gutter 16 when the main body portion 51 is brought into contact with the extending edge portion of the inner horizontal plate portion 16a in the gutter 16 on the upper surface of the beam gutter 17. The dimensions are set so that they touch each other.

The auxiliary horizontal plate portion (hereinafter referred to as the rear auxiliary horizontal plate portion 52) provided on the trailing edge side of the main body portion 51 has a flat plate shape extending substantially horizontally from the lower end edge of the main body portion 51 toward the rear. .. The size of the rear auxiliary horizontal plate portion 52 is larger than the dimension of the upper horizontal plate portion 22 provided on the base material 20. On the other hand, the auxiliary horizontal plate portion (hereinafter referred to as the front auxiliary horizontal plate portion 53) provided on the front edge side of the main body portion 51 has a flat plate shape extending substantially horizontally from the upper end edge of the gutter contact portion 55 toward the front. Is made up of. The auxiliary horizontal plate portions 52 and 53 are provided with auxiliary bending portions 56 and 57 at their extending edge portions, respectively. In the rear auxiliary horizontal plate portion 52, the auxiliary bending portion 56 extends upward, and in the front auxiliary horizontal plate portion 53, the auxiliary bending portion 57 extends downward. The auxiliary bent portion 56 of the rear auxiliary horizontal plate portion 52 is configured such that the vertical dimension is slightly smaller than the height of the base main body portion 21 of the base material 20, and is placed on the upper surface of the beam gutter 17. It is possible to arrange it between the upper horizontal plate portion 22 and the upper horizontal plate portion 22. As is clear from the figure, in the present embodiment, the cover portion 54 is extended forward from the upper end edge of the main body portion 51, and the auxiliary bending portion is extended upward from the front end edge of the front auxiliary horizontal plate portion 53. The hollow portion 58 is formed in the attachment 50 by extending the 57 and connecting the extension portions to each other. As is clear from the figure, the dimensions along the front and rear (short side) of the attachment 50 are shorter than those of the base material 20.

Reference numeral 60 in the drawing is a spacer member provided between the deck material 30 and the end beam 12 and between the deck material 30 and the joist 13. The spacer member 60 does not necessarily have to be provided, and the deck portion 10 may be formed only by attaching the deck material 30 to the base material 20.

According to the balcony configured as described above, since the edge end surface 30a of the deck material 30 is hidden by the main body 51 of the attachment 50, the edge end surface 30a of the deck material 30 cannot be seen even when viewed from the front side. , It is advantageous in terms of appearance quality. Further, since the attachment 50 is provided with the cover portion 54, the upper surface 30b of the deck material 30 is covered. Therefore, even if the edge end faces 30a of the deck material 30 are not accurately aligned at the time of assembly, the cover portion 54 does not appear to the outside, and the assembly work can be facilitated without impairing the appearance quality. become. Further, even if the deck material 30 is unevenly thermally stretched after assembly, the situation is not exposed to the outside and there is no possibility that the design is impaired.

Further, on this balcony, when it rains on the upper surface 30b of the deck material 30 in rainy weather, it is guided forward and falls downward from each front end edge. The rainwater that has fallen from the front end edge of the deck material 30 is received on the upper surface of the rear auxiliary horizontal plate portion 52 between the main body portion 51 and the auxiliary bending portion 56 of the attachment 50, and then directed toward the end beam 12 or the joist 13. Guided, it falls from the end and is received by the beam gutter 17. The rain that falls between the front girder 14 and the attachment 50 is received by the gutter 16 of the front gutter 14, guided toward the wife beam 12 or the joist 13, falls from the end, and is received by the beam gutter 17. Be done. The rainwater in the beam gutter 17 will be guided to the ground surface via the drainage gutter 18 after being guided forward.

During this time, a part of the rain that has fallen on the upper surface 30b of the deck material 30 will travel downward from between the deck materials 30. However, according to the balcony of the present embodiment, since the base material 20 is provided below the deck material 30, rainwater that has passed between the deck materials 30 is received by the base material 20. , There is no risk of falling directly to the surface of the earth. That is, since the rainwater that has reached the upper surface of the base material 20 is received by the fastening gutter portion 21a that opens upward, it is guided toward the end beam 12 or the joist 13 at the fastening gutter portion 21a, and falls from the end portion of the beam. It is received by the gutter 17. Further, the rainwater that has reached the upper surface of the base material 20 is guided as it is toward the end beam 12 or the joist 13, falls from the end portion, and is received by the beam gutter 17. Even if rainwater moving on the upper surface of the base material 20 moves toward the adjacent base material 20 on the way, it is received by the lower horizontal plate portion 23 between the base main body portion 21 and the bent portion 25 and reaches the ground surface. It will surely be guided to the beam gutter 17 without falling. Therefore, the rainwater that has passed between the deck members 30 does not directly fall to the ground surface.

Moreover, since the attachment 50 is provided with the auxiliary horizontal plate portions 52, 53 and the auxiliary bending portions 56, 57, as shown in FIGS. 7A and 7B, the inside of the front girder 14 is provided. By appropriately changing the facing position between the horizontal plate portion 16a and the auxiliary bending portion 57 and the facing position between the upper horizontal plate portion 22 and the auxiliary bending portion 56 of the base material 20, the base material 20 and the front girder located at the frontmost position are appropriately changed. Even for the deck portion 10'with different dimensions from the inner side surface 14a of 14, it is possible to deal with this while maintaining the function of preventing downward water leakage. Specifically, the distance between the attachment 50 and the base material 20 can be adjusted within the range of the dimensions of the upper horizontal plate portion 22 provided on the base material 20, and between the front girder 14 and the attachment 50. The adjustment is possible within the range of the dimensions of the auxiliary horizontal plate portion 53 provided on the attachment 50. As a result, even if the rectangular area 15 of the deck portion 10 is large or small in the actual work site, it can be easily dealt with by adjusting the position of the attachment 50.

In the above-described embodiment, the base material is arranged along the front girder, but the base material may be arranged along the end beam. In this case, it goes without saying that it is necessary to dispose an attachment between the base material and the end beam. Further, although the inner horizontal plate portion and the inner bending portion are integrally provided on the front girder which is the horizontal member, it is not always necessary to be integrally provided, and the inner horizontal plate portion is provided by attaching a separately configured member to the horizontal member. It can also be applied to those constituting the inner bent portion. It is not necessary that the inner bent portion provided on the cross member extends upward from the inner horizontal plate portion. Further, although the balcony in which the front girder is directly connected to the end beam and the joist is illustrated, it can also be applied to the one in which the end beam and the front girder are connected via a pillar.

Further, in the above-described embodiment, as the base material 20, the horizontal plate portion 22 extends from the upper portion on one edge portion, and the horizontal plate portion 23 extends from the lower portion on the other edge portion. Since the existing material is applied, one type of base material may be prepared, but the present invention is not limited to this, and the base material and both edge portions in which the horizontal plate portion extends from above to both edge portions. Two types of base materials in which the horizontal plate portion extends from below may be applied. Similarly, with respect to the attachment 50, the auxiliary horizontal plate portions may be extended from the same height position on both side edges, and auxiliary bending portions may be provided vertically from the individual auxiliary horizontal plate portions in the same direction. I do not care.

Further, in the above-described embodiment, since the cover portion 54 is provided on the attachment 50, as described above, the assembly work can be facilitated without impairing the appearance quality, or the deck generated after assembly can be facilitated. The attachment of the present invention does not necessarily have to have a cover portion, although the non-uniform heat elongation of the material has an action effect such as not being exposed to the outside. In this case, the main body of the attachment does not necessarily have to protrude above the upper surface of the deck material, and may be at the same height as the upper surface of the deck material.
