Description of the Related Art Like the wall panel connection structure of Japanese Patent Laid-Open No. 8-135051 shown in FIG. 7, a wall panel 21 is provided with a furring strip 20 attached along the vicinity of the edge of the wall panel body. The furring strip 20 is retracted from the end portion of the wall panel 21 to form a recess 22. The end portions of the wall panel 21 are opposed to each other to form a gap 24 between the outer wall members 23. Further, a joint material 25 having a substantially convex cross section is interposed between the end portions of the wall panels 21, 21, and each projection of the joint material 25 having a substantially convex cross section is fitted into the gap 24 and the recesses 22 on both sides. It fits. And, this outer wall material 23, 2
A sealing material 26 is attached to the gap 24 between the three.

However, in such a wall panel 21 connecting structure, since the side end surfaces of the wall panels 21 and 21 have to be contacted with each other and the joint material 25 must be interposed between them, it takes a lot of time and work to construct the outer wall. Since the joint material 25 with which the materials 23, 23 abut is made of metal such as aluminum or steel plate, it is difficult to absorb the dimension even if the dimension shrinks due to the temperature condition of the outer wall material. There is a problem that the sealing material 26 adhered to the gap 24 is easily separated by the side end portions of the outer wall materials 23, 23.
