[Means for Solving the Problems] In order to eliminate the above-mentioned drawbacks, the present invention provides a synthetic resin plinth board formed from a horizontal nail driving piece and a fitting portion to have an approximately inverted T-shaped cross section. A vertical joint is made up of two parts: a decorative surface part and an engaging part, and a metal decorative cap formed into a substantially T-shaped cross section, and the vertical joint is formed into an E-shaped cross section by combining the decorative cap and the floor board. By forming a waterproof fin made of soft synthetic resin on the fitting part of the synthetic resin paving board in the joiner,
The longitudinal ends of the wall material are always sealed due to the elasticity (restoring force) of the waterproof fins, preventing rainwater and wind from entering from the ends of the wall material. The present invention provides a vertical joint structure with improved weather resistance and design properties by covering the joints with the material.
