Can be installed with good workability.

  In the state where the cover 10 is attached to the base 9, as shown in FIG. 4, the cover plate portion 19 of the cover 10 covers the gap S across the outer surfaces of the side end portions of the exterior material 4 adjacent to the left and right. Placed in. At this time, the outer packing 21 is elastically contacted to the outer surface of the edge of the corresponding exterior material 4. That is, a watertight structure is formed between the cover 10 and the outer surface of the exterior material 4 by the outer packing 21. At this time, the inner packing 26 is elastically contacted to the side end face of each exterior material 4 facing the gap S between the exterior materials 4. The elastic contact of the inner packing 26 to the side end surface of the exterior member 4 is such that the left leg 22 is elastically deformed to the left by the central wall 12 and the right leg 23 is moved when the leg 20 is engaged with the mounting groove 11. By being elastically deformed to the right, it is performed with a strong pressing force. That is, according to the engagement of the leg 20 to the mounting groove 11, the construction work from the introduction of the leg 20 to the mounting groove 11 to the engagement and the elastic contact of the inner packing 26 to the exterior material 4 is performed with a single touch. Not only is the work possible and good workability is ensured, but also good water stoppage is ensured by strong elastic contact of the inner packing 26 to the exterior material 4 at the same time. As described above, according to the inner packing 26, a water stop structure is formed on the side end face of the exterior material 4 exposed in the gap S between the exterior materials 4.

  By the way, in the connection part of the upper and lower exterior members 4 connected by actual connection, rainwater that has fallen on the upper exterior member 4 enters the upper end surface of the lower exterior member 4 and at the upper end surface of the exterior member 4. Although the phenomenon of flowing in the lateral direction occurs (see arrow α in FIG. 9), in this example, as described above, a water-stopping structure is formed on the side end surface of the exterior material 4 by the inner packing 26. The rainwater that has flowed laterally along the upper end surface of the exterior material 4 can be stopped so that the rainwater does not enter the gap S between the exterior materials 4. Therefore, the rainwater flows down inside the exterior material 4 and is built. It is possible to prevent the foundation 2 and the like from getting wet and to prevent the deterioration of the building. In this example, the inner packing 26 is formed so as to lie up and down the cover 10 and is elastically contacted with all side end surfaces of the exterior material 4 exposed in the gap S between the exterior materials 4. Needless to say, the above-described effects can be obtained if the inner packing 26 is elastically contacted with at least the upper and lower connecting portions of the exterior material 4 on the side end face of the exterior material 4 exposed in the gap S.

  5 and 6 show a structure in which the exterior material 4 that is adjacently arranged on the left and right sides with the corner B of the protruding corner is connected using a joiner 8.

Since the inner packing 26 is attached to the left side surface of the protruding base region 27 of the left leg portion 22 and the right side surface of the protruding base region 27 of the right leg portion 23 to be the facing surface 29, the gap between the exterior materials 4 The inner packing 26 is elastically contacted to the side end face of each exterior member 4 facing S. The elastic contact of the inner packing 26 to the side end surface of the exterior member 4 is such that the left leg 22 is elastically deformed to the left by the central wall 12 and the right leg 23 is moved when the leg 20 is engaged with the mounting groove 11. By being elastically deformed to the right, it is performed with a strong pressing force. That is, not only the workability is improved but also the good water stoppage by the inner packing 26 is ensured by the engagement of the leg portion 20 with the mounting groove 11 in the joiner 8.

  As described above, according to the inner packing 26, a water stop structure is formed on the side end face of the exterior material 4 exposed in the gap S between the exterior materials 4. Therefore, even when connecting the exterior material 4 adjacent to the left and right using the joiner 8 at the corner B of the protruding corner, the exterior material 4 adjacent to the left and right using the joiner 8 at the portion A of the planar outer wall is connected. As in the case of connection, the inner packing 26 forms a water-stop structure on the side end surface of the exterior material 4, so that rainwater that has flowed laterally along the upper end surface of the exterior material 4 flows between the exterior materials 4. The rainwater is prevented from flowing inside the exterior material 4 to wet the foundation 2 of the building and the like, and the deterioration of the building is avoided. The rainwater that could not enter the gap S between the exterior materials 4 adjacent to the left and right flows down along the outer surface of the exterior material 4, but in this example, the draining piece 30 extends over the portion directly under the exterior. Therefore, the rain water that has flowed down the surface of the exterior material 4 reaches the drain piece 30 from the lower end of the exterior material 4 and is dripped from the lower end of the drain piece 30 onto the ground.
