As described above, according to the vertical joint structure according to the present invention, the metal decorative cap is fitted and integrated with the synthetic resin tile plate, so that the heat between the decorative cap and the tile plate is reduced. There is no bridge, no dew condensation occurs inside the skeleton on the back of the slab, and corrosion of the skeleton can be prevented. Insole th plate also can be formed in any shape for an extruded product made of synthetic resin, is simple form fitting claws of multiple stages. Since a plurality of fitting claws are formed on the stitch plate, it can be adjusted by the engagement depth in accordance with the wall material thickness. The engagement between the fitting claws of the synthetic resin floor plate and the engaging claws of the metal decorative cap is reliable and strong. Springback (elastic deformation force) also acts on the mating piece of the timber plate due to the gap formed in the mating portion of the timber plate, and a synergistic effect with the springback of the engaging piece of the decorative cap causes the engaging force. In addition, the workability is improved, and there is no decrease in the engaging force over time. Since a groove is formed at the lower end of the mating part of the timber plate, even if the fixing piece deforms following the unevenness (unevenness) of the skeleton, the deformation does not act on the mating part, and the gap becomes large. Does not narrow and does not adversely affect engagement. There are features and effects such as.
