Description

[Detailed description of the invention] This invention relates to a decorative board with a beautiful surface and high strength.

Metal siding, wood siding, PC board, etc. are known as architectural board materials, but all have smooth surfaces and are disliked for being too monotonous. The purpose of this invention is to provide a decorative board with a beautiful surface and high strength. One of the decorative boards of this invention that achieves the above purpose is a metal plate that is roll-formed on both sides. The feature is that a rising frame part is formed and a design or pattern is formed by unevenness on the bottom plate part using a press.The other feature is that a fiber-containing inorganic hardened material is laminated and fixed on the back side of the decorative board. It is characterized by the fact that

The attached drawing shows that the rising frame parts 1, 1 are formed by roll forming a metal plate, and the bottom plate part 2 is formed using a press.
On the back side of the decorative board 3, which has a design or pattern formed by unevenness,
A mixture of alkali-resistant glass fibers, cement, fine aggregate, acrylic synthetic resin emulsion, and water is sprayed and laminated to form a cement-based reinforcing layer 4, reinforcing bars 5 are placed inside the layer, and styrofoam is formed. A laminated decorative board is shown in which a mixed cement mortar 6 is poured, and a mixture 4 of alkali-resistant glass fibers, cement, fine aggregate, acrylic synthetic resin emulsion, and water is poured and laminated thereon.

In this invention, instead of the cement mortar 6, aerated cement mortar, aerated gypsum, a mixture of cement mortar or gypsum mortar with lightweight aggregate such as perlite or shirasu balloons may be used, and the reinforcing layer 4 is made of only cement. Alternatively, the fibers can be made of gypsum, and synthetic resin fibers such as asbestos fibers, shirasu wool, and nylon fibers can also be used.

The decorative board of the present invention is constructed as described above and is manufactured by roll forming and pressing, so it is suitable for mass production and can be manufactured economically.It also has high strength due to the unevenness of the upright frame and bottom plate. The laminated decorative board, in which a fiber-containing hydraulic inorganic cured material is laminated and fixed on the back side, has a high stiffness of the reinforcing layer, so the thickness of the metal plate can be made thinner, and the metal plate has a high resistance to water permeation. Not only can it prevent oxidation of the hydraulic inorganic cured product due to rainwater, etc., but it also has excellent sound insulation and fireproofing properties, and has the effect of beautifully finishing the surfaces of structures such as buildings. In this invention, the lamination and fixation of the hydraulic inorganic curing material to the metal plate may be performed not only by spraying but also by injection or casting.
