A gap 6 having a predetermined interval d2 is provided on the inner surface of the material P facing the outer surface of the outer end convex portion tip portion 5 of the material P.

  The gap d2 of the gap 6 may be set to be non-clearance with d2 = 0. However, the outer end convex portion tip 5 and the engaging projection 5a at one end of one decorative material P are arranged from above with this. In order to enable smooth insertion into the surface concave groove portion 2 of the other decorative material P to be connected, it is appropriate to set a clearance of an interval d2 (for example, about 0.3 to 1.0 mm). Further, the gap 6 with the predetermined interval d2 is used when a part of the decorative material after laying is removed for replacement or the like when a spatula or the like is inserted into the gap 6 and the end of the decorative material P is lifted off. It is used to cut the connecting portion of the decorative material P by inserting the cutting edge of the cutter when it is used or cannot be removed with a spatula or the like, and is therefore necessary within a certain range.

The engaging surface is provided. In addition, the cross-sectional shape of the engaging protrusion surface by the concave-convex fitting method of the engaging protrusions 3a and 5a of the decorative material P can be disconnected at least if an external force is applied, but can be easily connected. There is no particular limitation in the present invention as long as it is an engagement shape surface that does not release the holding.

As shown in FIG. 2, the decorative material according to claim 2 of the present invention has a thickness t of the base material of the decorative material P, a bottom surface thickness of the concave grooves on the substrate surface and the back surface, t1, The relationship between t, t1, and h is t = 2t1 + h, where h is the height of the outer end convex portion that constitutes the concave groove on the back surface. Thus, the engagement structure is provided in a balanced manner at the center portion of the entire thickness of the layer and can be locked, so that there is an effect that the workability and the work efficiency can be greatly improved.

  As the base material 1 for decorative material of the present invention, a molded body made of a thermoplastic resin is applicable. As the thermoplastic resin, polyolefin resins such as polypropylene and polyethylene are preferably used because of disposal problems and the like. However, the thermoplastic resin is not particularly limited thereto, and is particularly limited as long as it has various resistances and processability. Not what you want.

  In addition, a foaming agent is applied to the thermoplastic resin partly or entirely to form bubbles in layers on the back side, the front side, or the intermediate layer, or although not shown, the foams are dispersed throughout. You may make it provide elasticity (cushioning property) by forming. The expansion ratio is suitably about 1.1 to 10.0 times from the viewpoint of appropriate cushioning properties as a decorative material.

  Further, a wood filler such as wood powder may be used as a molding material in the thermoplastic resin. The average particle size of the wooden filler is suitably 1 to 200 μm, and the mixing ratio of the wooden filler in the portion containing the wooden filler is based on 100 parts by weight of the thermoplastic resin. It is appropriate that the amount is 10 to 500 parts by weight. A part containing the wood filler may be at least partially, or may be dispersed throughout and contain the wood filler.

  As a manufacturing method of the base material 1 for decorative material of the present invention, an injection molding method, a hot press molding method, a profile extrusion molding method, a cutting method, a mold casting method, and the like are applicable.

  As the decorative sheet 11 laminated on the decorative substrate 1, a thermoplastic resin similar to the thermoplastic resin or a sheet mainly composed of the thermoplastic resin can be used.

  The decorative sheet 11 is provided with a decorative pattern ink layer (pattern ink layer) by printing on the surface of the colored base sheet, and a transparent protective layer (sheet, film, coating layer) is formed thereon, and a top coat layer is formed on the surface. After coating, an embossed part is appropriately formed on the surface as necessary. This is laminated on the surface of the decorative board substrate 1 to complete the decorative material P of the present invention.

  As described above, the decorative material of the present invention has a structure in which the concave / convex fitting direction between the front and back concave grooves and the outer end convex portion for connecting the end portions thereof is perpendicular to the laying surface. Can be applied in sequence by simply fitting the side edge fitting part of the next cosmetic material onto the side edge fitting part of the decorative material already arranged on the laying surface, which can greatly improve the workability and construction efficiency. effective.

  In addition, since the decorative material of the present invention has a structure in which the concave and convex fitting direction is perpendicular to the laying surface, the decorative material and the structural material of the laying surface were scratched or soiled over the years after construction. In this case, you can easily remove and replace a part of the makeup material that is laid down, insert a spatula into the gap at the edge of the makeup material, lift the edge of the makeup material, and release the fit. It is possible to easily remove and replace only the material, and the newly replaced decorative material can be easily fitted and connected simply by pressing the end of the decorative material against the end of another decorative material from above. And has the effect of significantly improving the construction efficiency.

  In addition, the fitting portion of the decorative material of the present invention has a concavo-convex shape and thickness, and is provided with an engagement protrusion so as not to be easily detached in daily life, and has a structure that can be locked. Fixing by nailing is unnecessary, and there is an effect that the workability and construction efficiency can be greatly improved.

  Further, the decorative material fitting portion of the present invention is provided with a protrusion, and there is an effect that no push-up occurs even if the decorative base material P expands due to a temperature rise in a daily use environment.

  If a thermoplastic resin is used as the main material of the base material of the decorative material of the present invention, moderate elasticity can be obtained, thereby facilitating fitting and fixing and removal, and in the fitted state with external force during use, etc. Cannot be easily disengaged.

  In addition, the base material of the decorative material of the present invention is a molded body obtained by extrusion molding of a thermoplastic resin (the direction along the both ends of the base material on which the outer end convex part tip part and the concave groove part are formed is the extruding 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 laid like a conventional decorative base material. Unlike the asymmetrical shape in the direction parallel to the surface, the molded body is less likely to warp and exhibits excellent 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 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 base material surface. 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.
