Abstract

PROBLEM TO BE SOLVED: To enhance strength and design of a decorated face, to prevent deterioration in strength between a male type connection part and a female type connection part especially, and to improve workability. SOLUTION: In the center of a decorated face 1, a large recessed bar part 4 with a substantially trapezoidal cross section is formed in the longitudinal direction. In the center part of the decorated face 1 between the large recessed bar part 4 and each of a female type connection part 2 and a male type connection part 3, a small recessed bar part 5, which is smaller in dimension than the large recessed bar part 4 and provided with a V-shaped or a U-shaped cross section, is formed in the longitudinal direction. The female type connection part 2 in a covering material 1 is constructed of a downward external slanting face 2a with a desired inclination and a recess type fitting part 2b with a substantially U-shaped cross section. The male type connection part 3 is constructed of a downward external inclination face 3a formed into the same shape as the downward external slanting face 2a, a projection type fitting part 3b, which can be inserted into the recess type fitting part 2b and provided with a substantially wedge-shaped cross section, and a horizontal projecting tongue piece part 3c protruded horizontally from the projection type fitting part 3b to the outside.

Reference numeral 4 denotes a large concave portion having a substantially trapezoidal cross section formed in the longitudinal direction of the central portion of the decorative surfaces 1a and 1'a. Reference numerals 5 and 5 denote the large concave portion 4 and the female and male connecting portions 2. , 3 formed in the longitudinal direction of the central portion of the flat decorative surface 1a, 1'a, is a small concave portion having a substantially V or U-shaped cross section, and is shallower than the depth dimension of the large concave portion 4. And the width dimension is formed small. Reference numeral 6 denotes a downwardly folded goose formed at the end of the female connecting portion 2, and reference numeral 7 denotes an upwardly bent goby formed at the end of the horizontally projecting tongue-shaped portion 3 c of the male connecting portion 3. Reference numeral 8 denotes a core material uniformly filled in the back surface side of the surface material 1, that is, the concave section 1b, and is made of, for example, a novolak-type phenol foam resin, gypsum, asbestos, and other necessary heat insulating and fireproof materials. I have. Reference numeral 9 denotes a backing material, which is made of various materials such as an aluminum foil sheet and other fireproof and non-combustible cardboard.

[0008]

According to the present invention, male and female connecting portions are formed on both longitudinal edges of a surface member having a concave cross section formed of a strip having a required width and a required length, and the male and female connecting portions are formed. In a building interior / exterior plate in which a surface material portion between the portions is a decorative surface, a large concave portion having a substantially trapezoidal cross section is formed in a longitudinal direction of a central portion of the decorative surface, and the large concave portion and the male and female are formed. A small V-shaped cross-section concave section having a smaller dimension than the large concave section is formed in the longitudinal direction of the center of the decorative surface between the mold connecting sections, and the female connecting section of the surface material is formed with a required gradient. A female connecting portion comprising a downwardly outwardly inclined surface and a concave fitting portion having a substantially U-shaped cross section continuous with a lower end of the downwardly outwardly inclined surface, while connecting the male type connecting portion to the female type connecting portion. At the lower end of the downward outward slope and the same downward downward slope as the downward outward slope A convex fitting portion having a substantially wedge-shaped cross-section, which can be fitted into the concave fitting portion of the female connecting portion, and a horizontal projecting tongue-like portion projecting substantially horizontally outward from the convex fitting portion. Since it is a male connecting part consisting of
The shape and dimensions of the large trapezoidal section with a substantially trapezoidal cross section formed in the longitudinal direction at the center of the decorative surface, and the small concave section with a V or U cross section formed on the left and right sides of the decorative surface The design of the decorative surface is remarkably improved by the groove pattern produced by the difference in the depth dimension of the groove, and the decorative surface is prevented from being twisted and pebbled. By making the concave streak on the decorative surface close to the mold connecting part smaller than the concave streak on the central decorative surface and making the depth of the groove shallow, the strength of the male and female connecting parts is prevented from weakening. There is an effect that the workability can be excellent.
