[0022]

As described above, according to the vertical joint structure of the present invention, since the metal decorative cap is fitted and integrated via the synthetic resin pawl, the space between the decorative cap and the pawl is provided. Because there is no thermal 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,
The formation of the multistage fitting pieces and the waterproof fins is simple.
Since the multi-stage fitting piece is formed on the synthetic resin floor plate, it can be adjusted by the engagement depth according to the dry wall material thickness. The engagement between the fitting piece of the synthetic resin floor plate and the engaging claw of the metal decorative cap is reliable and strong. Since the waterproof fin made of a soft synthetic resin material is always in close contact with the end of the dry wall material under elasticity, the waterproofness and airtightness are maintained. Since a gap was formed between the fitting part and the waterproof part, the rainwater, which was prevented from entering by the waterproof fin, immediately flowed downward through the gap, so that the rainwater fell into the fitting groove of the synthetic resin floor plate. It does not penetrate, the engaging portion of the metal decorative cap does not rust due to rainwater, and the engaging force can be maintained for a long time. There are features and effects such as.
