Accordingly, it is necessary to apply a sealant having a curing property to the connection between the column 12 and the front girder 13, the connection between the column 12 and the end beam 14, and the connection between the column 12 and the intermediate joist 15. As a result, it is possible to improve the workability in assembling the balcony.

  Moreover, the respective water collecting members 20 and 30 are formed by omitting the side wall portion of the portion in contact with the column 12, the front girder 13, the end beam 14 and the intermediate joist 15, which is advantageous in terms of member cost It becomes. Furthermore, in the bottom wall portions 21 and 31, contact surface portions 26 and 36 are provided on the edge facing the column 12, and the sealing material 40 is interposed between the contact surface portions 26 and 36 and the side surface of the column 12. It is like that. For this reason, the contact area with the sealing material 40 can be largely secured with respect to the side surface of the water collection members 20 and 30 and the pillar 12, and desired water tightness can be secured. In addition, while the previously formed sealing material 40 is attached to the water collecting members 20, 30, the other surface of the sealing material 40 is pressed against the column 12. For this reason, for example, due to the load when a person gets on the balcony, the column 12 and the front girder 13, the end beam 14, and the intermediate joist 15 are displaced relative to each other, thereby the column 12 and the water collecting members 20, 30 Even if relative displacement occurs between them, the sealing material 40 can maintain the pressure-contacted state by appropriately sliding on the side surface of the column 12, and there is no risk of affecting the water tightness. In addition, in the water collection member 30 for intermediate parts, 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 is difficult to fit the column 12. However, in the water collecting member 30 for the intermediate portion, the seal application recess 38 having a rectangular cross section is provided in a portion facing the side surface of the column 12, and the curable application sealing material 40 'is provided in the seal application 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 surface of the water collecting member 30 for the intermediate portion and the side of the column 12, and a triangular seal can be prevented. There is no risk of damage.

  Further, in the balcony of the embodiment, the sealing material 40 is interposed also 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 water collection units 20A and 30A due to the influence of heavy rain or the like, the water of the water collection units 20A and 30A does not leak to the outside. When the water received by the girder 17 falls from the end to the girder 18, a part of the water moves along the lower surface of the girder 17 and falls downward at a position beyond the girder 18 There is a risk of However, even if the water dropped downward along the lower surface of the girder 17 falls between the contact surface portions 23, 33 of the main side wall portions 22A, 32A and the column 12, the water collecting members 20, 30 The seal material 40 of the contact surface portions 23, 33 in contact with the side surfaces of the front girder 13 in the side wall portions 22A, 32A functions to prevent water leakage to the outside.

  By the way, as a place which provides a balcony, a plane view may not necessarily be a rectangle, and as shown in Drawing 15, plane view may be provided in a trapezoidal portion. In such a balcony, the front girder 13 connected to the pillar 12 is inclined with respect to the outer surface of the building, so when the above-described water collecting members 20 and 30 are attached, part of the auxiliary cover portions 21B and 31B May project further forward than the front girder 13. However, according to the above-described water collecting members 20 and 30, the inclined inward side wall 25 is provided at a portion which is inward of the auxiliary side walls 22B and 32B in the auxiliary cover portions 21B and 31B. Therefore, as shown in FIG. 15, if the inward side wall portion 25 is left and the protruding auxiliary side wall portions 22B and 32B are cut out along the separating groove, the outline inclined with respect to the side surface of the pillar 12 is obtained. The water collection members 20 and 30 which have these can be comprised. Thereby, the situation where a part of auxiliary cover parts 21B and 31B is exposed outside from front girder 13 can be prevented, and the situation where auxiliary cover parts 21B and 31B are directly exposed to rain can be prevented.

  In addition, in the embodiment mentioned above, although the balcony is illustrated as an outdoor structure, it is possible to apply also to other outdoor structures. Moreover, although the outdoor structure provided with the middle joist 15 between the end beams 14 is illustrated, it is not necessary to necessarily have the middle joist. In this case, it is not necessary to provide the middle portion water collection member 30 as the water collection member, and it is needless to say that only the corner water collection member 20 may be provided. In addition, since a dedicated intermediate water collecting member 30 is provided at the connection portion between the intermediate joists 15 and the pillars 12 and the front girder 13, it is advantageous in terms of operability, but the water collection for the corners individually It is also possible to provide a member 20. Furthermore, since the seal material accommodation portion 24 is provided in the water collection member 20, 30, the position where the seal material 40 is provided in the contact surface portions 23, 33 is accurately defined. Although a certain degree of water tightness can be expected, it is not always necessary to provide a sealing material storage portion.
