At this time, since the water stop spatula 16 is elastically deformed, the water stop spatula 16 is caught on the upper outer wall panel 2a and the support member 7 cannot be removed.

  After removing the elastic water-stopping material 10, the support member 7, and the draining member 9 as described above, the elastic water-stopping material 10 is replaced with a new one, and the support member 7 and the water-cutting member 9 are replaced with, for example, the water stopping spatula 16 Then, maintenance such as exchanging the draining spatula 18 is performed, and then the support member 7, the draining member 9, and the elastic water stop material 10 are reattached to the horizontal joint 2c. Specifically, the support member 7 is inserted into the horizontal joint 2c of the outer wall panel together with the watertight support material 28 adhered to the upper surface thereof from the outdoor side, and is inserted into the fixing hole 17 of the fixing piece 14 and the through hole 12 of the mounting member 5. The screw 11 is inserted and fixed, and then the draining member 9 is inserted into the horizontal joint 2c from the outside, and the held claw 31 is held in the holding groove 30 and the locked claw 8 is locked to the locking claw 6. Further, the replaced new elastic water blocking material 10 is pushed into the gap between the lower end of the upper outer wall panel 2a and the draining arm portion 20 from the outdoor side of the horizontal joint 2c.

  Thus, the draining structure 1 of this embodiment can remove and attach the support member 7, the draining member 9, and the elastic water stop material 10 which need maintenance, such as repair and replacement | exchange, very easily. Therefore, the draining structure 1 can be maintained without carrying out a large-scale construction such as removing the outer wall panel 2.

  Needless to say, the embodiment of the present invention is not limited to the above-described embodiment, and can be appropriately changed without departing from the scope of the idea of the present invention.

  In the present embodiment, the water stopping spatula 16 and the water draining spatula 18 are fitted and fixed at the ends of the support member 7 and the water draining member 9, respectively. For example, as shown in FIG. 10, the water stop spatula 16 and the water draining spatula 18 may be bonded and fixed at the ends of the support member 7 and the water draining member 9, respectively.

  Further, the draining structure 1 according to the present embodiment has the attachment member 5 that is inserted at one end between the frame 3 and the beam 4 constituting the housing of a building such as a house and fixed by bolts 25 and nuts 26. Although the support member 7 is fixed to the mounting member 5 on the indoor side of the outer wall panel 2 and protrudes in the outdoor direction, it is not limited to this. For example, as shown in FIGS. 11 and 12, the support member 7 may be one in which the bent piece 15a of the support arm portion 15 is fixed to the lower outer wall panel 2b. That is, for example, the bent piece 15a has an insertion hole 34 into which the screw 33 can be inserted, and the support member 7 can be attached and detached by screwing into the screw hole 35 formed on the outdoor side surface of the lower outer wall panel 2b. The structure may be freely fixed.

  If comprised in this way, since the attachment member 5 becomes unnecessary, while being able to reduce a number of parts and being fixed to the outdoor side of the lower side outer wall panel 2b, compared with the case where it fixes to the back of the horizontal joint 2c. The work becomes easier.

  The draining structure 1 according to the present invention can be suitably used as the draining structure 1 in a house that can be used for an extremely long period of time ranging from 100 years to 200 years.
