The side plate portion 64 extends upward from the extending edge portion of the bottom plate portion 63 and is connected to a portion constituting the upper surface 20a of the base main body portion 21. That is, in the portion of the base material 20 facing the deck material 30, a seat surface 60a that is substantially horizontal at a height position lower than the upper end of the partition wall portion 61 outside the gutter-shaped passage 21a is formed, and the seat surface is formed. A gutter portion 65 is formed by an inclined plate portion 62, a bottom plate portion 63, and a side plate portion 64 at a portion adjacent to 60a. An inclined surface 62a formed by the inclined plate portion 62 is continuously formed between the inner bottom surface 65a of the gutter portion 65 and the seat surface 60a.

Further, each of the partition wall portions 61 of the gutter-shaped passage 21a is provided with an edge plate portion 26. The edge plate portion 26 extends substantially horizontally from the upper end of the partition wall portion 61, covers both side edges of the gutter-shaped passage 21a, and slightly protrudes so as to cover the upper part of the seat surface 60a. The amount of protrusion of the edge plate portion 26 toward the seat surface 60a is substantially equal to the protrusion dimension of the mounting plate portion 53 of the holding metal fitting 50 described above from the protruding piece 52a.

With respect to the base material 20 having the above-described configuration, the holding metal fittings 50 mount the mounting plate portions 53 and 54 on the seat surface 60a, respectively, and from this state, form the seat surface 60a via the mounting plate portions 53 and 54. It is attached to the base material 20 by screwing the attachment screw S2 into the flat plate portion 60. At this time, if the protruding edge portion of the wide mounting plate portion 53 is arranged between the seat surface 60a and the edge plate portion 26, the holding metal fitting 50 engages with the base material 20 before the mounting screw S2 is screwed. It will be in the state of being. In the holding metal fitting 50 attached to the base material 20, the holding plate portion 51 is in a state of facing the upper surface 20a of the base material 20, and the holding portion of the deck material 30 is sandwiched between the holding plate portion 51 and the upper surface 20a of the base material 20. 31 can be held. Further, since the seat surface 60a is provided horizontally, it is possible to easily perform the work of screwing the mounting screw S2.

In the balcony configured as described above, the rain that has fallen on the upper surface 30a of the deck material 30 in rainy weather is guided forward according to the inclination of the deck material 30 and falls downward from the individual front end edges. Rainwater that has fallen from the front end edge of the deck material 30 is received by the upper surface of the rear auxiliary horizontal plate portion 42 between the main body portion 41 and the auxiliary bending portion 46 of the attachment 40, and then directed toward the end beam 12 or the intermediate joist 13. It is guided by the beam, falls from the end, and is received by the beam gutter 17. The rain that falls between the front girder 14 and the attachment 40 is received by the gutter 16 of the front gutter 14, guided toward the wife beam 12 or the middle joist 13, and falls from the end to the beam gutter 17. It will be accepted. The rainwater in the beam gutter 17 is guided forward and then guided to the ground surface via the drain gutter 18.

During this time, a part of the rain that has fallen on the upper surface 30a 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 from the deck portion 10 to the ground surface.

That is, the rainwater that has reached the upper surface 20a of the base material 20 is received by the gutter-shaped passage 21a that opens upward, so that it is guided toward the end beam 12 or the intermediate joist 13 in the gutter-shaped passage 21a and falls from the end. It is received by the beam gutter 17. Further, the rainwater that has reached the upper surface 20a of the base material 20 is guided as it is toward the end beam 12 or the intermediate joist 13, falls from the end portion, and is received by the beam gutter 17. Even if rainwater moving on the upper surface 20a of the base material 20 moves toward the adjacent base material 20 on the way, it is received by the lower horizontal plate portion 23a between the base body portion 21 and the bent portion 23b, and is received by the lower horizontal plate portion 23a on the ground surface. It will surely be guided to the beam gutter 17 without falling to. Therefore, the rainwater that has passed between the deck materials 30 does not directly fall to the ground surface.

Here, some of the rainwater that has passed through the deck material 30 reaches the seating surface 60a of the base material 20. However, in the above balcony, the seat surface 60a is provided at a position lower than the lower surface 30b of the deck material 30, and the gutter portion 65 extending along the longitudinal direction is provided at a position lower than the seat surface 60a. An inclined surface 62a that is gradually lowered toward the gutter portion 65 is provided at a portion adjacent to the seat surface 60a. Therefore, the rainwater that has reached the seat surface 60a is guided to the gutter portion 65 through the inclined surface 62a and discharged to the beam gutter 17 via the gutter portion 65, and does not stay on the seat surface 60a. As a result, even when the holding metal fitting 50 is attached to the base material 20 by applying the mounting screw S2, there is no possibility of causing problems such as rust and corrosion to the mounting screw S2 and the holding metal fitting 50. Moreover, the seat surface 60a is provided outside the gutter-shaped passage 21a, and further, the edge plate portion 26 is provided at the upper end of the partition wall portion 61 interposed between the gutter-shaped passage 21a and the seat surface 60a. It is provided. Therefore, even if a large amount of rainwater flows into the gutter-shaped passage 21a, there is no possibility that the water will reach the seat surface 60a, and problems such as rust and corrosion may occur in the mounting screw S2 and the holding metal fitting 50. It will be possible to prevent it reliably.

In the above-described embodiment, the seat surface 60a is provided outside the gutter-shaped aisle 21a, but the seat surface 60a may be provided inside the gutter-shaped aisle 21a. In this case, the inclined surface 62a does not need to be in contact with the inner bottom surface of the gutter-shaped passage 21a, and may be inclined so as to be lowered from the seat surface 60a toward the gutter-shaped passage 21a. Further, since the balcony is arranged so that the extending direction of the base material 20 intersects the extending direction of the deck material 30, water such as rainwater that has passed between the deck materials 30 can flow. It will be received by the gutter-shaped passage 21a, the lower horizontal plate portion 23a of the base material 20, and the gutter portion 65, but even if the base material 20 and the deck material 30 extend in the same direction to form the deck portion 10. good. Further, although the attachment 40 is interposed between the front girder 14 and the base material 20, it is not always necessary to provide the attachment 40.

Further, in the above-described embodiment, the inclined surface 62a forms a part of the gutter portion 65, but of course, an inclined surface may be provided separately from the gutter portion 65 as long as it is continuous with the seat surface.
