JP 2000-204740 A

  Conventionally, the seams of the finished plate material were processed by the various methods described above. However, the method (a) has a problem of high cost because it is necessary to increase the processing accuracy and construction accuracy of the finished plate material. In the method (b), not only is it difficult to harmonize the color of the caulking agent and the color of the finished plate, but there is a problem that the filling operation of the caulking agent is troublesome. Although it was excellent in workability, there was a problem that it was difficult to harmonize the color of the joint material and the color of the finished plate material.

  Further, regarding the method (c), the joint material is made inconspicuous by making the portion exposed on the surface side of the finished plate material transparent or semi-transparent (see Patent Document 1). In the method, the thickness of the transparent or translucent part cannot be sufficiently ensured, so that there is a problem that the color visually recognized through the transparent or translucent part cannot be deepened.

  SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a joint material and joint structure which can be easily constructed at a low cost, and can have a deep color while preventing it from being noticeable.

  According to the first aspect of the present invention, “a linear or semi-transparent main body portion that fills the gap 16 in the linear joint material 10 disposed in the concave gap 16 secured on the side of the end of the finish plate 14. 18 and a colored portion 20 that is formed integrally with the main body 18 and is disposed on the back side of the gap 16 with respect to the main body 18.

  In the present invention, since the color of the colored portion 20 can be visually recognized from the outside through the transparent or translucent main body portion 18 filling the gap 16, it is possible to increase the color while preventing the joint material 10 from conspicuous. it can. In addition, since light can enter the transparent or translucent main body 18, it is possible to prevent black shadow lines from being generated in the gap 16.

    The invention described in claim 2 is the “joint material 10” described in claim 1, wherein “the groove 32 for scattering light is formed on the end surface of the main body portion 18 exposed from the gap 16”. It is characterized by that.

    In the present invention, since the light can be scattered by the grooves 32 formed on the end face of the main body 18, even when the thickness of the main body 18 is thin, the joint material 10 is prevented from standing out and has a deep color. Can be made.

    According to the third aspect of the invention, in the joint structure 24 including the linear joint material 10 disposed in the concave gap 16 secured on the side of the end portion of the finish plate material 14, the joint material 10 has a gap The joint structure 24 includes: a transparent or translucent main body portion 18 that fills 16; and a coloring portion 20 that is formed integrally with the main body portion 18 and disposed on the back side of the gap 16 from the main body portion 18. Is.

    The present invention is a joint structure 24 using the joint material 10 according to claim 1.

    The invention described in claim 4 is the “joint structure 24” described in claim 3, wherein “the end portion of the main body portion 18 exposed from the gap 16 protrudes from the surface of the finished plate 14”. Features.

    In the present invention, since the end portion (surface portion) of the main body portion 18 protrudes from the surface of the finish plate material 14, no recess is formed in the joints A and B of the finish plate material 14, and the finish plate material 14 or the surface thereof is formed. It is possible to prevent the applied decorative layer 14b from turning over.

    According to the “joint material” according to claims 1 and 2, the joint material can be easily attached to the concave gap secured on the side of the end of the finished plate material by adhesion or the like. Further, since light can be taken into the transparent or translucent main body, it is possible to prevent black shadow lines from being generated in the gaps. Therefore, it is not necessary to increase the processing accuracy and construction accuracy of the finished plate material, and the processing and construction costs can be greatly reduced. Furthermore, since the transparent or semi-transparent main body fills the gap, light propagates in the main body in the entire inner space of the gap, and it is possible to prevent uneven coloring of the colored portion visually recognized from the outside. , The color can be deepened.

    FIG. 1 is a perspective view showing a joint material 10 to which the present invention is applied, and FIG. 2 is a cross-sectional view showing the joint material 10. The joint material 10 can be applied to the joints between the finished plate materials constituting the walls, floors, ceilings, etc., but in the following, as shown in FIGS. 3 and 4, the finished plate material constituting the wall 12 is used. A case where the present invention is applied to 14 seams A will be described as an example.

    Here, the finished plate material 14 (FIGS. 3 and 4) has a base material 14a made of plywood, MDF, volcanic glass composite plate (trade name: dielite) or a composite material thereof, and the base material 14a. A decorative layer 14b made of a decorative veneer, decorative paper, a decorative sheet, a paint, or the like is formed on the surface. Moreover, the end surface of the finish board | plate material 14 is formed perpendicularly | vertically with respect to the surface and the back surface. Therefore, when the gap 16 is secured by the “watermark” at the joint A between the finished plate members 14, the cross-sectional shape of the gap 16 becomes a concave quadrangle as shown in FIG. The finished plate 14 may be a board having a large surface area or a tile having a small surface area.

  As shown in FIGS. 1 and 2, the joint material 10 is a linear member disposed in a concave gap 16 (FIGS. 3 and 4) secured in the joint A between the finished plate materials 14. A transparent or semi-transparent main body 18 and a colored portion 20 that is formed integrally with the main body 18 and is disposed on the back side of the gap 16 from the main body 18.

    The main body 18 is made of a transparent or translucent synthetic resin material such as PVC (vinyl chloride), acrylic, ABS, AS (acrylonitrile / styrene), PP (polypropylene), PE (polyethylene), polycarbonate, etc. The cross-sectional shape is set to a substantially square shape along the inner surface of the gap 16. Further, the width of the main body portion 18 gradually increases from the end portion exposed from the gap 16 (hereinafter referred to as “front surface portion”) to the opposite end portion (hereinafter referred to as “back surface portion”). The width is set to be narrow, and a relationship of L1> L3> L2 is established among the width L1 of the front surface portion, the width L2 of the back surface portion, and the width L3 of the gap 16. In addition, the main-body part 18 does not necessarily need to be colorless, and may be colored as long as it does not impair translucency.

    The colored portion 20 is made of colored synthetic resin materials such as PVC (vinyl chloride), acrylic, ABS, AS (acrylonitrile / styrene), PP (polypropylene), PE (polyethylene), polycarbonate, peeled material, plywood, MDF, etc. It is made of a colored wood material or a colored metal material such as aluminum or steel, and the bottom surface of the colored portion 20 is curved in a concave shape so that an adhesive accommodating space 22 can be secured between the bottom surface of the gap 16. . Further, the width of the coloring portion 20 is set to be approximately the same as the width L2 of the back surface portion of the main body portion 18. The colored portion 20 is desirably opaque so that the color can be viewed faithfully from the outside. However, if it is not necessary to consider the influence of the bottom color of the gap 16, the colored portion 20 is colored. It may be transparent or translucent.

    When the colored portion 20 is formed of a synthetic resin material, the colored portion 20 and the main body portion 18 can be simultaneously formed by two-layer extrusion, but the colored portion 20 and the main body can be formed regardless of the material. The portions 18 may be formed separately, and then both may be integrated by a method such as adhesion, fusion, caulking, fitting, or the like. Furthermore, you may form the colored part 20 by apply | coating a colored paint to the back surface of the main-body part 18, or sticking a sheet | seat or a veneer.

    The total height of the joint material 10 including the main body portion 18 and the coloring portion 20 is set slightly higher than the depth of the gap 16. This is to prevent adverse effects (such as “turning up of the finished plate material 14 or the decorative layer 14 b, accumulation of dust, etc.) due to the formation of a recess in the joint A of the finished plate material 14. However, if the surface portion of the main body portion 18 greatly protrudes from the surface of the finished plate member 14, the joint material 10 is conspicuous and the design properties are impaired. Therefore, the protrusion amount L4 is preferably about 1 mm. Further, the width of the joint material 10 is not particularly limited, but it is desirable that the maximum width is 3 mm or more in order to sufficiently capture light into the main body portion 18. Furthermore, the thickness of the main body portion 18 is desirably 3 mm or more so as to give a depth to the color of the colored portion 18 visually recognized from the outside.

    Such a joint material 10 is used to form a joint structure 24 at the joint A between the finished plate members 14 as shown in FIGS. 3 and 4. When the joint structure 24 is configured, as shown in FIG. 4, a plurality of finishing plate members 14 are arranged side by side on the upper surface of the base material 26, and the joint A has a concave gap 16 that accommodates the joint material 10. Secured. The joint material 10 is disposed in the gap 16, and the back surface of the joint material 10 and the bottom surface of the gap 16 are joined using an adhesive 28.

    The width L2 of the back surface portion of the main body portion 18 and the coloring portion 20 in the joint material 10 is narrower than the width L3 of the gap 18 (L3> L2), and therefore the main body portion 18 in a state where the joint material 10 is disposed in the gap 18. A space 30 is secured on the side of the back surface portion and the colored portion 20. Therefore, the adhesive 28 that has not been stored in the adhesive accommodating space 22 protrudes from the adhesive accommodating space 22 and escapes to the space 30, and it is possible to prevent the joint material 10 from being raised by the adhesive 28. The protrusion amount L4 (FIG. 3) of the main body portion 18 protruding from the surface of the plate member 14 can be within an appropriate range.

    In such joint structure 24, the surface portion of the main body portion 18 constituting the joint material 10 protrudes from the upper surface of the finish plate member 14, and the width L 1 of the surface portion is wider than the width L 3 of the gap 16. Since (L1> L3) is set, even when a gap is formed between the inner surface of the opening of the gap 16 and the outer surface of the joint material 10, the gap can be hidden by the surface portion of the joint material 10.

    In the joint material 10 described above, the end face exposed from the gap 16 of the main body portion 18 is formed flat, but a groove 32 for scattering light as shown in FIG. 5 is formed on this end face. May be. When such a groove 32 is formed, light can be scattered by the groove 32, so that even when the thickness of the main body portion 18 is thin, the joint material 10 can be prevented from conspicuous and the color can be deepened. It becomes possible. Therefore, the applicable range can be expanded to the seam B where the depth of the gap 16 such as “actual peel” shown in FIG. 6 or “phase jump” shown in FIG.

    Further, in the above-described embodiment, the joint material 10 and the joint structure 24 are applied to the gap 16 secured in the joint A or B between the finish plate materials 14. However, the joint material 10 and the joint structure 24 are finished. The present invention can be widely applied to the concave gap 16 secured on the side of the end portion of the plate material 14. For example, as shown in FIG. 8, the gap 16 secured between the finished plate material 14 and the floor material 34 is also applicable. Applicable.
