[Conventional technology]

In general, a wall material formed in a sandwich structure using a metal plate as a surface material, a synthetic resin foam as a core material, and a sheet-shaped material as a back surface material or a wall material made of an inorganic material in a horizontal stretch When forming, the vertical joints, so-called vertical joints, are formed by butting the wall materials in the longitudinal direction, and there is a method in which the vertical joints are simply butted and the caulking material is planted in the vertical joints. However, the caulking material has a drawback that it cannot maintain waterproofness and designability for a long period of time due to weathering change and ultraviolet deterioration. Further, in the wall material using the synthetic resin foam as the core material, the deformation of the metal plate whose end portion in the longitudinal direction is the surface material is likely to occur, and it is not easy to plant the caulking material. Further, since the wall material made of an inorganic material is brittle, the end portion of the wall material is likely to be chipped, which is disadvantageous in that the aesthetics of the vertical joints are lacking. Therefore, there is a method of using a joiner having an H-shaped cross section for the vertical joint. However, in this method, it is necessary to insert the wall material into the U-shaped member formed on both of the joiners, and at this time, the wall material is deformed, damaged, and the joiner itself is deformed. There was a flaw that was lacking.
