Also, rainwater that has fallen along the outdoor side surface of the hollow portion 2 is drained from the drainage hole 13 formed in the caulking material 5 by the external water cutting material 11. Even if rainwater flows from the engagement portion with the holder 16 to the back side of the upper draining material 11a, it flows along the upper surface of the lower draining material 11b and is drained to the outdoor side of the base foundation 12. Therefore, rainwater is effectively drained. In addition, the ventilation circulation of the upper and lower hollow portions 2 is not impaired.

Next, FIG. 4 shows an example in which the inner and outer drainers 8 and 11 are provided on both the indoor side and the outdoor side at the lower end of the extruded cement board 1 arranged vertically. An indoor draining material 8 (internal draining material) provided in the same manner is provided, and an outdoor draining material 11 is provided on the outdoor side.

Engagement with the groove 26, the distal end engaging portion 29 at the bent portion at the lower end edge is engaged with the engaging portion 30 at the lower end of the holder 16 at the outward end.

According to the above configuration, since the indoor end of the outside drainer 11 is arranged below the outdoor end of the inner drainer 8, it is guided to the outdoor side by the inner drainer 8. The drained rainwater flows down along the upper surface of the inclined edge 25 of the outside water cutting material 11 and is discharged to the outside from the drainage hole 13 formed in the caulking material 5, so that the drainage efficiency is good. Further, part of the rainwater flows around the backside of the outside water cutting material 11 and is further guided to the hollow portion 2 of the lower extruded cement plate 1 and discharged downward to the outside. Therefore, rainwater is effectively prevented from entering the indoor side. In addition, the drainage material 8 can be sandwiched and fixed between the angle material 3 and the extruded cement board 1, and the construction can be performed easily.

Part of the rainwater circling behind the upper drainer 11a flows along the upper surface of the lower drainer 11b and is drained to the outside. The other part of the rainwater flows downward along the hollow part 2 of the lower cement board 1 and is eventually drained. Therefore, since the rainwater is drained three times, reliable drainage can be realized. In addition, since the lower draining material 11b is superposed and fixed on the upper surface of the extruded cement board 1, and the upper draining material 11a is engaged with the holder 16, the construction is easy.

That is, the outside water cutting material 11 is fixed to the holder 16 fixed on the outdoor side surface of the base 12 by overlapping. The configurations of the holder 16 and the outside water cutting material 11 are the same as those in FIG.

According to this example, the rainwater guided to the outdoor side by the internal water cutting material 8 flows down along the inclined upper surface of the external water cutting material 11 and is discharged to the outdoor side through the drain hole 13 of the caulking material 5. . A part of the rainwater goes around the back side of the outside water cutting material 11, but is discharged to the outdoor side of the base foundation 12 below the outside water cutting material 11. Therefore, rainwater is effectively prevented from entering the indoor side.

It may be configured to be stopped and attached so that the inside water cutting material 8 and the outside water cutting material 11 are connected via a step. The holder 16 can also serve as a drainage joint.
Further, as shown in FIG. 10, the inside of the outside water cutting material 11 is engaged with the outside of the inside water cutting material 8, and the outside water cutting material 11 is connected to the inside water cutting material 8 by fixing with screws 34 to form It may be. A drain joint similar to that shown in FIG. Further, the lowermost end of the extruded cement board 1 can support the support block 24 on the base 12 instead of the angle member 3.

As described above, by integrally forming the inner water cutting material 8 and the outer water cutting material 11, the flow of rainwater is also integrated, and drainage and ventilation are more reliable. That is, the hollow portion of the extruded cement board can be dried quickly by ventilation.
