Description

  The present invention relates to an architectural decorative board.

  Conventionally, as the final finishing construction of the outer wall of the wooden building, the roof plaster part P is covered with the windbreak plate 19a as shown in FIG. 14, or the eaves part Q is covered with the nose cover plate 19b as shown in FIG. The appearance around the roof R is trimmed.

  In the case of a two-story building, as shown in FIGS. 14 and 16, a curtain 19c is attached to the boundary T of the wall surface between the first floor part 17 and the second floor part 18 to accentuate the exterior of the wall surface of the building. Widely done.

By the way, the windbreak plate 19a, the nasal cover plate 19b, the curtain plate 19c, etc. are formed by using a long and narrow plate-like body as a base and applying various decorations to the edge and the surface. For example, as shown in a cross section in FIG. 17, several types of decorative boards are prepared by building modules from the widest one 20a to the narrowest one 20d, and the widths corresponding to the size of the building respectively. Decorative plates 20a to 20b were used. (Non-Patent Document 1)

That is, in order to solve the above-described problems, the decorative board for building of the present invention has the same decoration formed on the longitudinal edges on both sides in the width direction of the longitudinal body, and the longitudinal body is cut and divided into arbitrary widths. The split piece can be used as a target decorative plate, and a pinhole is inserted along the width direction on the back surface of the longitudinal end of the vertically long main body to insert a cutting line positioning pin to be locked to the starting end of the black line. It is formed at predetermined intervals.
The decorative board for architecture of the present invention has the same decoration formed on the longitudinal edges on both sides in the width direction of the longitudinal main body, and uses each divided piece as a target decorative board by cutting and dividing the longitudinal main body into an arbitrary width. The notch groove in the length direction is formed at regular intervals along the width direction only at both ends in the length direction of the back surface of the vertically long main body, and the notch groove has a shape in which the groove inner wall has parallel surfaces. It is characterized by making.

  Since the same decorative edge is formed on both sides, if it bisects with a line parallel to the center line in the width direction, any cut piece can be used as a decorative board for construction, and only one type should be molded It is possible to adjust a building decorative board having an arbitrary width at a construction site.
