By devising such a joint shape, there is an effect that the interior workability and construction efficiency of floor materials, wall materials, ceiling materials, etc. can be greatly improved.

Thus, since the decorative material of the present invention has a structure in which the concave and convex fitting direction between the front and back concave grooves and the outer convex portions for connecting the end portions is perpendicular to the laying surface, it is applied. On the other hand, it is possible to perform construction by simply fitting the side edge fitting part of the next cosmetic material from above onto the side edge fitting part of the decorative material already arranged on the laying surface, greatly improving the workability and construction efficiency. There is an effect that can be done.

Since the base material of the decorative material of the present invention uses a thermoplastic resin as a main material, moderate elasticity can be obtained, which makes it easy to fix and remove, and in the fitted state, external force during use. Etc., it cannot be easily disengaged.

In the case where the base material of the decorative material of the present invention is a molded body by extrusion molding of a thermoplastic resin (the direction along the both ends where the outer end convex portion and the concave groove portion of the base material are formed is the extrusion direction). Since the concave / convex fitting direction at both ends of the base material is perpendicular to the laying surface, the cross-sectional shape of the base material is a point-symmetrical shape, and the concave / convex fitting direction is the same as that of a conventional decorative base material. Unlike the asymmetrical shape in the direction parallel to the laying surface, the molded body is less likely to warp and exhibits excellent effects in moldability and productivity.

In addition, it is important that the mating part of the base material in the decorative material of the present invention is easy to fit at the time of construction, cannot be easily detached after daily use after construction, and can be easily removed at the time of replacement at the time of repair. However, as the physical properties required for the decorative base material at that time, an appropriate bending stress and restoring property are required. That is, it has a so-called hinge property such that when a certain external force is applied during fitting and removal, the fitting portion opens and closes again when the external force is released.

In order to obtain an appropriate bending stress and restorability, a polyolefin-based resin is preferable as the resin used for the substrate. In a hard resin such as polystyrene and polyester, a large force is required to open the fitting portion, and at the same time, there is a poor restoration property when the fitting portion is opened too much, which may come off. Since the base material has a composite structure in which a wood filler such as wood powder is mixed, the strength properties can be adjusted by adjusting the mixture quantitatively or positionally, for example, increasing the content of wood powder As a result, the bending stress can be increased.

Further, in the present invention, the bending stress can be reduced while maintaining appropriate strength properties by foaming the base resin to form a resin / foam (void) composite structure.

In addition, the resin base material containing the above wood-based filler reduces the strength when cutting from the resin itself in addition to bending stress and resilience. Even in this case, it can be easily cut and removed with a cutting edge such as a cutter.

Furthermore, the tension and flatness of the entire base material can be adjusted by extending and sticking the decorative sheet laminated to the base material to the uneven part of the fitting part, thereby enhancing the “hinge” There is.

Further, the decorative material of the present invention is a resin molded body made of a thermoplastic resin, or a base material made of a wooden resin molded body containing a thermoplastic resin and a wooden filler, or a resin molded body thereof, and is foamed. Since a base material made of a resin foam molded body or a wood resin foam molded body is used, and a decorative sheet mainly composed of a thermoplastic resin similar to the thermoplastic resin is laminated on the surface of the base material, It is also excellent in workability such as cutting and nailing, and high design properties with a decorative sheet can be obtained.

In addition, when a base material made of a wood resin molded body or a wood resin foam molded body is used as a decorative material, the visual and tactile sensation of the base material itself can be applied to the decorative material without laminating a decorative sheet on the surface of the base material. It can have a typical wood texture.

Moreover, when a decorative sheet mainly made of the same thermoplastic resin as the base material is used for the decorative sheet laminated on the surface of the base material, there is no need to separate the base material from the decorative sheet. In particular, in the case of using polyolefin resin as a thermoplastic resin, it is inexpensive and excellent in processability, and waste materials that are not suitable for recycling depending on the application mode can be incinerated. is there.
