Description

DETAILED DESCRIPTION OF THE INVENTION According to the present invention, a fitting convex piece protruding outward is formed on one side plate of a substantially U-shaped member opening downward, and a fitting convex piece concave inwardly is formed on the other side plate. An architectural board comprising a groove formed therein, a partially protruding tile-like convex portion on the upper surface of the substantially U-shaped member, and a transparent coating layer provided only on the surface of the tile-like convex portion, Its purpose is
Even though it is an interlocking type and easy to install, after installation, the glossy tiles become an integrated finished surface that looks like mortar has been applied, and the tile-like protrusions stand out, giving a three-dimensional effect. The purpose of the present invention is to provide a construction board that gives a dignified appearance.

Hereinafter, the present invention will be explained based on the drawings.

The construction board shown in FIGS. 1 and 2 is an embodiment of the present invention, in which a fitting convex piece 3 protruding outward is formed on one side plate 2 of a substantially U-shaped member 1 that opens downward. , a fitting groove 4 concave inwardly is formed in the other side plate 2', and a tile-shaped protrusion 5 is formed partially protruding on the upper surface of the substantially U-shaped member 1. A transparent coating layer 6 is provided only on the surface of the portion 5.
The substantially U-shaped member 1 is made of hard synthetic resin, and a substantially U-shaped metal core material 7 is inserted therein.
It is integrally extruded with the fitting convex piece 3 and the fitting groove 4, and at this time, a joint material 8 made of hard synthetic resin is placed on the outer surface of one side plate 2, and a soft material is placed on the outer surface of the other side plate 2'. A packing material 9 made of synthetic resin is integrally provided. The tile-shaped protrusions 5 are rectangular and are formed on the upper surface of the substantially U-shaped material 1 in a row in the longitudinal direction. In this case, the metal core material 7 is inserted into the substantially U-shaped material 1 made of hard synthetic resin, so that the tile-like convex portions 5 are clearly formed without losing their shape. It is. The back side of the substantially U-shaped material 1 after the tile-like convex portions 5 are formed is filled with a synthetic resin foam 10, and an aluminum sheet 11 is attached to the back side of the synthetic resin foam 10. . The transparent coating layer 6 has tile-like convex portions 5 as shown in FIG.
A photopolymerizable paint is applied only to the surface of the surface. That is, the conveyor 12
First, a photopolymerizable paint is applied only to the surface of the tile-like convex portion 5 on the upper surface of the substantially U-shaped material 1 that is conveyed in the direction a, using a sponge roll 13 that rotates in synchronization with the direction a, and then After leveling the coated surface in section l until it becomes an uneven surface with appropriate smoothness, the photopolymerizable paint is polymerized and cured by irradiation with ultraviolet rays by the ultraviolet irradiation device 14, and the transparent coating layer 6 is formed. It is something that can be done. The surface of the transparent coating layer 6 is glossy, has a texture due to the diffused reflection effect of the smooth uneven surface, has a good texture, and is very similar to the surface of a ceramic tile. Therefore, the construction board can be easily constructed by inserting and fitting the fitting convex pieces 3 into the fitting grooves 4 and sequentially connecting them, as shown in FIG. After the connection is completed, the tile-shaped convex portions 5 stand out and the seamless joints become inconspicuous, creating an integrated finished surface that looks like the glossy rectangular tiles are covered with mortar, creating a solid and three-dimensional effect. is obtained. In addition, in this embodiment, especially after the connection construction, the sealing material 9 is interposed in the joint, so it is highly waterproof, and the joint is covered and hidden by the joint material 8, so it looks good, and the shape is approximately U-shaped. The back side of the shaped material 1 is filled with synthetic resin foam 10 and the aluminum sheet 11 is attached to the back side, so it has excellent heat insulation and soundproofing properties, and also has a texture when the surface of the substantially U-shaped material 1 is struck. It is rich.

In addition, in the construction board of the present invention, a plurality of pairs of fitting convex pieces 3 and fitting grooves 4 may be formed as in the embodiment shown in FIG. A metal core material 7 is laminated on the back side of the mold material 1, and tile-like protrusions may be provided with random shapes and arrangements as in the embodiment shown in FIG. In the architectural board of the invention,
It is possible to apply gravure, offset, screen, etc. printing to the surface of the tile-shaped convex portion and then provide a transparent coating layer.In this case, if the printed area is raised by screen printing, an even more three-dimensional effect can be obtained. It is something that will make you rich.

As described above, the construction board of the present invention has a substantially U-shaped member that opens downward, and has a fitting convex piece that protrudes outward on one side plate, and a fitting convex piece that is concave inward on the other side plate. A concave groove is formed, a partially protruding tile-like protrusion is formed on the upper surface of the substantially U-shaped member, and a transparent coating layer is provided only on the surface of the tile-like protrusion.
It can be easily constructed by inserting and fitting the mating convex pieces into the mating grooves and connecting them one after another.However, after the connection construction, some parts protrude and a transparent coating layer is formed on the surface. The tile-like protrusions are visible compared to other parts where the transparent coating layer is not provided, and the seamless seams are not noticeable, creating an integrated finished surface that looks like the glossy tiles are covered with mortar. This gives a solid feel with a three-dimensional feel.
