[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to modular building elements such as blocks, tiles, and sheets that are used, for example, as building materials or as decorations for furnishings such as furniture. Regarding the provision of this type of product that is rich in sex.

[Prior Art] Conventionally, in a building that is easily visible to the public, the best way to achieve a -MIF is to apply a paint prepared in a color close to that of a natural surface to bring out the design properties of the building.

Also, for example, blocks used for curbstones and block walls contain mortar, colored pigments, and sand.

Colored concrete blocks are used, which are made by pouring a mixture of gravel, cement, etc. into a mold and hardening it by steam heating.

On the other hand, tiles that are often used as interior and exterior materials are generally made of ceramics, linoleum, or the like.

Furthermore, decorative sheets made of vinyl chloride and sheets with patterns transferred thereto are used as decorative sheets for furnishings.

[Problems to be Solved by the Invention] By the way, the coating process relies on the skilled work of the coating operator, which is time-consuming, lacks reproducibility, and takes a long time. Despite the effort put into its preparation, it often peeled off or chipped due to sunlight, wind and rain, making it impossible to maintain its beautiful appearance for a long period of time.

Colored concrete blocks also have disadvantages such as a long time required for heating and drying to produce a product, being heavy and difficult to handle, and being susceptible to impact and easily breaking.

Furthermore, since tiles and sheets are basically patterned on flat surfaces, such as brightly colored patterns, this is sufficient to meet the demand for decorations that look or resemble natural objects. It was difficult to say that they were being met.

This invention was made in view of these circumstances, and provides a decorative cover that can be mass-produced, is light, hard to break, is easy to install, and has an excellent three-dimensional surface pattern. It is weather resistant, stain resistant, easy to clean, scratch resistant, impact resistant, lightweight, and sound absorbing. The purpose of the present invention is to provide a surface cover which is further added with various functions such as being low in cost, having a unique texture, being strong, and not scattering even if broken.

[Means for Solving the Problems] A first means of the present invention for achieving the above-mentioned problems is to engrave the surface of a plate-like object itself, which is shaped to cover any surface with a rubber or plastic material. It has an undulating pattern.

Such an undulating pattern can be easily obtained by injection molding or press molding using a mold engraved with an undulating pattern.

The undulating pattern formed on the surface as described above is preferably a natural real bark pattern such as cedar bark, or a log pattern with wood grain and knots.

In addition, the above-mentioned undulating pattern is such that the thickness of the plate-like material at the deepest groove part is at least 2 mm, and the height from the bottom of the groove part to the top of the highest raised part does not exceed 3 mm. It is best to make sure that all surfaces between the groove and the raised part are sloped so that they can be seen from the front.

The polymer materials used for the rubber and plastics are:
Weather-resistant AES resin, ABS resin, or AC
So-called engineering plastics such as 5II resin are suitable.

A second aspect of the present invention for achieving the above object is to coat or laminate the surface layer of the plate-like object having the above-mentioned undulating pattern, or to provide a foam layer on the plate-like object, or to provide the plate-like object with a foam layer. By providing an inexpensive inner layer or by providing a layer containing various fillers for a plate-like object,
This is a multi-layered plate-like material.

Furthermore, a third aspect of the present invention which achieves the above-mentioned object is to put a reinforcing filler inside the plate-like object.

By preparing a plurality of such decorative covers and covering the surface of the object to be decorated, a mimetic object having a predetermined undulating pattern can be obtained.

As shown in FIG. 2, such an undulating pattern is such that the thickness h +++In of the plate-like body at the deepest groove portion 2a is at least t2 mm, and the highest raised portion 2b is formed from the groove portion 2a. Maximum height h□8 is 3mm
By making the side surfaces from the grooves to the ridges all outward-facing inclined surfaces, it is easy to extract the mold from the undulating pattern of the mold.

Also, according to the undulating pattern shaped as above,
In particular, the shearing force of the raised portion 2b, which tends to break due to external force, can be increased and strengthened.

In addition, as in the above embodiments, in addition to the unidirectional flow of linear grooves and linear ridges that resembles cedar bark,
For example, it may be due to the fine irregularities on the surface of natural stone, the satin pattern, or the undulations of the stone grain pattern.These undulations create a warm and natural three-dimensional feeling as if it were made of natural materials. It becomes something.

FIG. 3 shows a cross-sectional view of a decorative front cover showing an embodiment of the second invention of the present invention. This is what was done. The fluororesin coating layer 3 has good water repellency, improves the weather resistance of the plate-like object 1, and has functions such as being resistant to staining, easily removing stains, and being resistant to scratches.
