Further, contact surface portions 26, 36 are provided on the edges of the bottom wall portions 21, 31 facing the pillar 12, and a sealing material 40 is interposed between the contact surface portions 26, 36 and the side surface of the pillar 12. I am trying to do it. Therefore, it is possible to secure a large contact area with the sealing material 40 with respect to the side surfaces of the water collecting members 20 and 30 and the pillar 12, and it is possible to secure desired watertightness. In addition, while the preformed seal material 40 is attached to the water collecting members 20 and 30, the other surface of the seal material 40 is pressed against the pillar 12. Therefore, for example, due to the load when a person gets on the balcony, the pillar 12 and the front girder 13, the end beam 14, and the intermediate joist 15 are relatively displaced, whereby the pillar 12 and the water collecting members 20, 30 are displaced. Even if a relative displacement occurs between the two, the sealing material 40 can be maintained in a pressure-welded state by appropriately sliding on the side surface of the pillar 12, and there is no possibility of affecting the watertightness. In the water collecting member 30 for the intermediate portion, since the pillars 12 are fitted between the auxiliary cover portions 31B, the sealing material 40 is attached to the contact surface portion 36 provided on the auxiliary cover portion 31B. It becomes difficult to fit the pillar 12. However, in the water collecting member 30 for the intermediate portion, a seal coating recess 38 having a rectangular cross section is provided in a portion of the pillar 12 facing the side surface, and a curable seal material 40'is provided in the seal coating recess 38. It is applied and cured. Therefore, a large contact area with the curable sealing material 40'can be secured with respect to the side surfaces of the water collecting member 30 for the intermediate portion and the pillar 12, and the situation of forming a triangular seal can be prevented, so that the watertightness is improved. There is no risk of damage.

Further, in the balcony of the embodiment, the sealing material 40 is also interposed between the contact surface portions 23 and 33 of the main side wall portions 22A and 32A and the side surface of the pillar 12. Therefore, even if a large amount of water is stored in the catchment portions 20A and 30A due to the influence of heavy rain and the like, the water in the catchment portions 20A and 30A does not leak to the outside. When the water received by the gutter 17 falls from the end to the beam gutter 18, some water moves along the lower surface of the gutter 17 and falls downward at a position beyond the gutter 18. There is a risk of However, even if the water that has fallen downward along the lower surface of the gutter 17 falls between the contact surface portions 23 and 33 of the main side wall portions 22A and 32A and the pillar 12, the main water collecting members 20 and 30 are used. In the side wall portions 22A and 32A, the sealing material 40 of the contact surface portions 23 and 33 that abuts on the side surface of the front girder 13 functions, and a situation in which water leaks to the outside can be prevented.

By the way, as the place where the balcony is provided, the plan view is not always rectangular, and as shown in FIG. 15, the plan view may be provided in the trapezoidal portion. In such a balcony, since the front girder 13 connected to the pillar 12 is inclined with respect to the outer surface of the building, when the above-mentioned water collecting members 20 and 30 are attached, a part of the auxiliary cover portions 21B and 31B. May protrude forward from the front girder 13. However, according to the water collecting members 20 and 30 described above, the auxiliary cover portions 21B and 31B are provided with the inward side wall portions 25 inclined inward from the auxiliary side wall portions 22B and 32B. Therefore, as shown in FIG. 15, if the inner side wall portion 25 is left and the protruding auxiliary side wall portions 22B and 32B are cut along the groove for separation, the outer shape is inclined with respect to the side surface of the pillar 12. The water collecting members 20 and 30 having the above can be configured. As a result, it is possible to prevent a situation in which a part of the auxiliary cover portions 21B and 31B is exposed to the outside from the front girder 13 and a situation in which the auxiliary cover portions 21B and 31B are directly exposed to rainfall.

In the above-described embodiment, the balcony is illustrated as the outdoor structure, but it can also be applied to other outdoor structures. Further, although an outdoor structure having an intermediate joist 15 between the end beams 14 is illustrated, it is not always necessary to have an intermediate joist. In this case, it goes without saying that it is not necessary to provide the intermediate water collecting member 30 as the water collecting member, and only the corner water collecting member 20 needs to be provided. Further, since a dedicated intermediate water collecting member 30 is provided at the connecting portion between the intermediate joist 15 and the pillar 12 and the front girder 13, it is advantageous in terms of activity, but the water collecting for corners is individually provided. It is also possible to provide the member 20. Further, since the sealing material accommodating portion 24 is provided on the water collecting members 20 and 30, the position where the sealing material 40 is provided on the contact surface portions 23 and 33 is accurately defined, and the sealing material 40 is always provided. A certain degree of watertightness can be expected, but it is not always necessary to provide a sealing material accommodating portion.
