Can be installed at the same time.
[0018]
In the corner portion of the building, as the draining material 2, the corner corner draining material 2 a having a substantially L-shaped horizontal section projecting toward the front side and the horizontal section having a substantially L-shaped projecting toward the back side are formed. Using the entrance corner draining material 2b, the both ends of the exit corner draining material 2a and the entrance corner draining material 2b are constructed so as to overlap the ends of the linear long draining material 2 located on both sides. Is. Here, the surface of the water draining sloped piece 3 provided on the outlet corner drainer 2a and the surface of the water draining sloped piece 3 provided on the entrance corner drainer 2b are also narrow recesses as in the case of the linear long drainer 2. Or the convex horizontal stripe part 4 is formed.
[0019]
In addition, the connecting member 5 for connecting the linear draining materials 2 is also provided with an inclined piece that is inclined downward so as to be lower toward the distal end side.

In the state in which the draining material 2 and the outer wall material 1 are constructed as described above, the draining inclined piece 3 which is inclined downward so as to be lower toward the tip of the draining material 2 is lower than the lower end of the outer wall material 1 as shown in FIG. In FIG. 5, the outer wall material 1 protrudes outward from the surface.
[0021]
Thus, the rainwater flowing down from the surface of the outer wall material 1 flows on the draining inclined piece 3 projecting outward from the surface of the outer wall material 1 below the lower end of the outer wall material 1 and flows on the surface of the draining inclined piece 3. In this case, even if rainwater is blown upward along the surface of the draining inclined piece 3 by the wind, the wall flows down along the draining hanging piece 8 and flows down from the lower end of the draining hanging piece 8. Intrusion is prevented by the material receiving piece 7, and even if it rises along the wall material receiving piece 7, it is returned by the water return piece 9 to prevent further intrusion. Furthermore, even if water intrudes beyond the water return piece 9, the presence of the fixing vertical piece 6 can surely prevent further intrusion of water.
[0022]
By the way, when the rain water flowing down from the outer wall material 1 flows on the surface of the draining inclined piece 3, the narrow horizontal stripe 4 is formed on the surface of the draining inclined piece 3, so that the rainwater flows down in the vertical direction as it is. As shown in FIG. 4, in the concave horizontal stripe 4 portion, the water droplet 15a moves laterally along the horizontal stripe portion 4 and becomes larger, while the other horizontal water drop 15b is in contact with the other water droplet 15b. Becomes a larger water droplet 15c, and the larger water droplet 15c straddles the two horizontal streak portions 4 to form a larger water droplet, and the water droplet is enlarged while repeating the above, resulting in a state of a large water droplet. It is something that falls. Thus, when it is dropped in the state of large water droplets, vertical streaks such as raindrops can be prevented.
[0023]
The action of enlarging the water droplets 15 by the horizontal streaks 4 is performed in the same way on the drained corner draining material 2a, the corner draining material 2b, the connecting member 5 and the stop member 16, and vertical streaks such as raindrops. Is to prevent.
[0024]
Here, the arrangement is such that the horizontal streaks 4 respectively provided in the linear long draining material 2, the protruding corner draining material 2a, the entering corner draining material 2b, the connecting member 5 and the stop member 16 are continuous in the lateral direction. By doing so, water droplets can flow laterally so as to extend over the adjacent horizontal stripes 4 and can be enlarged.
