Therefore, since the sealing material or caulking material, which is also a durable adhesive, has a high viscosity, it is difficult for the sealing material or caulking material to flow into the gap between the back surface side portion of the end surface of the outer wall material and the side surface of the spacer portion, and the outer wall material Difficult to adhere to the back side of the end face.
That is, the bonding area between the sealing material or the caulking material and the end surface of the outer wall material is narrowed, and there is a high possibility that the bonding between the two will be peeled off due to the shrinkage of the outer wall material. Watertightness of joint of outer wall material is not high.

As shown in FIG. 2, the joint structure of the outer wall material of this example is such that the fixing portions 5 on both sides of the joiner are respectively
It is fixed by sandwiching it between the end of the ceramic-based outer wall material 11 such as a rectangular cement plate and the wall base 12, and the back side edges of the end faces of the outer wall materials 11 on both sides are the roots of the spacer portion 2 at the center of the joiner. The spacer portion 2 of the joiner is projected to the joint 13 between the end faces of the outer wall members 11 on both sides. A caulking material 14 made of a synthetic resin such as acrylic, modified silicone or urethane is filled in a recess between the surface of the spacer portion 2 of the joiner and the end surfaces of the outer wall material 11 on both sides. The joint 13 between the end faces is watertight.

In the spacer portion 2 of the joiner of this example, both side surfaces 3 are inclined flat surfaces having a V-shape, and the gap between the back surface side portion of the end surface of the outer wall member 11 and the side surface 3 of the spacer portion 2 is wide. Therefore, when filling the caulking material 14,
Even if the material has a high viscosity, it easily flows into the gap between the back surface side portion of the end surface of the outer wall material 11 and the side surface 3 of the spacer portion 2, and extends along the inclined plane of the side surface 3 of the spacer portion 2 to the depth of the gap. It is pushed in and adhered to the entire end surface of the outer wall material 11.
