The reference plate portion 52 extends from the substantially central portion of the pressing plate portion 51 so as to be substantially perpendicular. The width of the reference plate portion 52 is the same as that of the pressing plate portion 51. Protruding pieces 52 a are provided at both corners of the extending edge portion of the reference plate portion 52. The attachment plate portions 53 and 54 are flat plate portions extending from the protruding edge portion of the protruding piece 52a so as to be substantially parallel to the pressing plate portion 51. The interval between the mounting plate portions 53 and 54 is configured to be larger than the width dimension of the bowl-shaped passage 21 a provided in the base material 20. As is apparent from the drawing, one mounting plate portion 53 has a larger width than the other mounting plate portion 54 and protrudes inward from the protruding piece 52a.

  In the base material 20 to which the holding metal fitting 50 is attached, a seating surface 60a is formed on the both sides of the outside of the bowl-shaped passage 21a. The seat surface 60a is configured on the upper surface of the flat plate portion 60 provided so as to be horizontal from the upper portion of the partition wall portion 61 located on both sides of the bowl-shaped passage 21a toward the directions away from each other. The position of the seat surface 60 a is set lower than the upper end of the partition wall 61. More specifically, the distance between the upper end of the partition wall 61 and the seating surface 60 a is set to be slightly smaller than the projecting dimension of the projecting piece 52 a from the reference plate part 52. Further, this distance is such that the head of the mounting screw S2 is separated from the upper surface 20a of the base material 20 even when the mounting screw S2 is screwed in a state where the mounting plate portions 53 and 54 of the holding metal fitting 50 are arranged on the seating surface 60a. It is set not to protrude.

  An inclined plate portion 62, a bottom plate portion 63, and a side plate portion 64 are continuous with the flat plate portion 60 constituting each seating surface 60a in a direction away from the bowl-shaped passage 21a. The inclined plate portion 62 extends so as to be gradually lowered from the edge portion of the flat plate portion 60. The bottom plate portion 63 extends horizontally from the lowermost end of the inclined plate portion 62. 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 20 a of the base body portion 21. That is, a substantially horizontal seating surface 60a is configured at a position lower than the upper end of the partition wall portion 61 outside the bowl-shaped passage 21a at a portion of the base material 20 facing the deck material 30a. A flange portion 65 is constituted by the inclined plate portion 62, the bottom plate portion 63, and the side plate portion 64 at a portion adjacent to the portion 60a. Between the inner bottom surface 65a of the flange portion 65 and the seat surface 60a, an inclined surface 62a formed by the inclined plate portion 62 is continuously formed.

  Furthermore, the edge part 26 is provided in the partition part 61 of the bowl-shaped channel | path 21a, respectively. The edge plate portion 26 extends substantially horizontally from the upper end of the partition wall portion 61 and covers the both side edges of the bowl-shaped passage 21a and slightly protrudes so as to cover the upper portion of the seat surface 60a. The protruding amount of the edge plate portion 26 toward the seat surface 60a is substantially equal to the protruding size of the mounting plate portion 53 from the protruding piece 52a in the holding metal fitting 50 described above.

  With respect to the base material 20 having the above-described configuration, the holding metal fitting 50 mounts the mounting plate portions 53 and 54 on the seating surface 60a, and configures the seating surface 60a via the mounting plate portions 53 and 54 from this state. The flat plate portion 60 is attached to the base material 20 by screwing a mounting screw S2. At this time, if the protruding edge portion of the wide attachment plate portion 53 is disposed between the seat surface 60a and the edge plate portion 26, the holding metal fitting 50 is engaged with the base material 20 before the attachment screw S2 is screwed. It will be in the state. The holding metal fitting 50 attached to the base material 20 is in a state in which the pressing plate portion 51 faces the upper surface 20 a of the base material 20, and the sandwiching portion of the deck material 30 between the pressing plate portion 51 and the upper surface 20 a of the base material 20. 31 can be held. Further, since the seating 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, rain that has fallen on the upper surface 30a of the deck member 30 in the rain is guided forward according to the inclination of the deck member 30, and falls downward from the respective front end edges. Rainwater that has dropped from the front edge of the deck material 30 is received on 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. Then, it falls from the end and is received by the beam rod 17. The rain that falls between the front girder 14 and the attachment 40 is received by the girder 16 of the front girder 14, guided toward the end beam 12 or the intermediate joist 13, and falls from the end portion to reach the girder 17. It is accepted. The rainwater of the beam fence 17 is guided forward and then guided to the ground surface via the drainage fence 18.

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

  That is, since rainwater that has reached the upper surface 20a of the base material 20 is received by the bowl-shaped passage 21a that opens upward, the rainwater is guided toward the end beam 12 or the intermediate joist 13 in the bowl-shaped passage 21a, and falls from the end. It is received by the beam 樋 17. Further, the rainwater that has reached the upper surface 20 a of the base material 20 is directly guided toward the end beam 12 or the intermediate joist 13, falls from the end portion, and is received by the beam rod 17. Even if the 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 main body portion 21 and the bent portion 23b, It is surely guided to the beam rod 17 without falling. Therefore, a situation in which rainwater that has passed between the deck materials 30 falls directly on the ground surface is not caused.

  Here, some of the rainwater that has passed through the deck material 30 reaches the seating surface 60 a of the base material 20. However, in the above-mentioned balcony, the seat surface 60a is provided at a position lower than the lower surface 30b of the deck material 30, and the flange portion 65 extending along the longitudinal direction is provided at a position lower than the seat surface 60a, and An inclined surface 62a that is gradually inclined downward toward the flange 65 is provided at a portion adjacent to the seat surface 60a. For this reason, the rainwater that has reached the seat surface 60a is guided to the flange portion 65 through the inclined surface 62a and is discharged to the beam rod 17 through the flange portion 65, and does not stay on the seat surface 60a. Accordingly, even when the holding metal fitting 50 is attached to the base material 20 by applying the attachment screw S2, there is no possibility of causing problems such as rust and corrosion to the attachment screw S2 and the holding metal fitting 50. Moreover, the seat surface 60a is provided outside the bowl-shaped passage 21a, and further, the edge plate portion 26 is provided at the upper end of the partition wall section 61 interposed between the bowl-shaped passage 21a and the seat surface 60a. It is provided. For this reason, even when a large amount of rainwater flows into the bowl-shaped passage 21a, there is no possibility that the water will reach the seat surface 60a, and there will be a situation in which problems such as rust and corrosion occur on the mounting screw S2 and the holding bracket 50. It can be surely prevented.

  In the embodiment described above, the seat surface 60a is provided outside the bowl-shaped passage 21a. However, the seat surface 60a may be provided inside the bowl-shaped passage 21a. In this case, the inclined surface 62a does not need to be in contact with the inner bottom surface of the bowl-shaped passage 21a, and may be inclined so as to be lowered from the seat surface 60a toward the bowl-shaped passage 21a. Moreover, since the balcony arrange | positioned so that the extension direction of the base material 20 may cross | intersect with the extension direction of the deck material 30, water, such as rain water which passed between the deck materials 30, is shown. Although it is received by the bowl-shaped passage 21a, the lower horizontal plate portion 23a of the base material 20, and the hook portion 65, the deck portion 10 may be configured by extending the base material 20 and the deck material 30 in the same direction. good. Furthermore, although the attachment 40 is interposed between the front beam 14 and the base material 20, the attachment 40 is not necessarily provided.

  In the above-described embodiment, the inclined surface 62a constitutes a part of the flange portion 65. However, an inclined surface may be provided separately from the flange portion 65 as long as it is continuous with the seat surface.
