~■ The padding board is made of synthetic resin and the decorative cap is made of metal, and since the padding board is made of synthetic resin, the heat from the decorative cap does not propagate to the structure, and no condensation occurs on the structure. However, it was impossible to pass the fireproof structure test and the fireproof structure test if the plinth panels were made of synthetic resin. In addition, the decorative cap was unstable, and the aesthetics were poor because the left and right sides fit differently with the wall material. Furthermore, (2) is a two-metal structure, which has drawbacks such as thermal bridges that cause dew condensation inside the structure and corrode the structure. Furthermore, it is very difficult to use a metal plate for the padding and form multiple stages of mating claws at the mating part, and it is not possible to form it with the precision that can be achieved with synthetic resin extrusions. There was a problem with the looseness after it settled.

0004

[Means for Solving the Problems] In order to eliminate such drawbacks, the present invention provides a siding plate formed from a horizontal nail driving piece and a fitting portion into a substantially inverted T-shaped cross section, and a decorative surface portion. In a joiner for vertical joints, which is composed of two members: a decorative cap formed into a substantially T-shaped cross section from a and an engaging part, and whose cross section is formed into an E-shaped cross section by combining the decorative cap and a siding board.
A fitting member made of synthetic resin and having a substantially U-shaped cross section and having multiple stages of fitting claws protruding inward from the inner surface of the internal insertion groove is inserted and integrated into the fitting groove of the main part of the board, and After the siding board is fixed by protruding the tips of two guide pieces formed on the siding board at an angle outward to form a support piece, the wall material is installed, and after the wall material is installed. By fitting the engaging part of the decorative cap to the fitting part of the siding board, construction is facilitated, and it has fire resistance performance that can pass the fire protection structure test and fireproof structure test, and supports the siding board. The present invention relates to a vertical joint structure that prevents the decorative cap from wobbling and fits well by supporting the back side of the decorative surface part of the decorative cap after construction with a piece, and also forms vertical joints with improved workability and design. .
