Description

  The present invention relates to a plate material, a connection body thereof, and a production method of the plate material, and relates to a plate material such as a decorative board, a construction panel, a building material, an interior material, furniture, a display panel, or a connection body thereof.

  Conventionally, a plurality of wood plates and the like are laminated and bonded to a plate material such as a decorative plate, a construction panel, a building material, an interior material, furniture, and a display panel, and in some cases, a decorative paper is bonded to the surface.

Japanese Patent Laid-Open No. 11-100833 JP 2002-11737 A JP 2004-44251 A

  However, a plywood laminated and bonded with a plurality of such wood boards is heavy and inconvenient to carry. Therefore, it is also conceivable to make the inside of the plate material hollow, to make the front plate and the back plate, and to connect the front plate and the back plate at the periphery. However, although this is lighter, since the inside is hollow, it is difficult to fix the nail to the plate material even if the nail is hit, and it is difficult to connect and fix the plate materials together.

  The present invention has been made in order to solve the above-mentioned problems, and the object of the present invention is to fix the struck nail to the plate material despite being lightweight, and to connect and fix the plate materials together. It is easy to do.

  In order to achieve the above object, the present invention provides two outer plates made of a material that is hardly parallel to each other and hardly deformed, and is located between the two plates and is substantially parallel to the outer plate. One or more inner plates made of a material that is difficult to deform, interposed between the outer plates and the inner plates, and integrally connected to the outer plates and the inner plates. The plate body was kept substantially parallel and had a large number of cavities, and the outer plate body and an intervening body made of a material that was softer and easier to deform than the inner plate body were provided.

  As a result, since the inner plate body is located between the two plate bodies, the hit nail can be fixed to the plate material through the inner plate body, and the plate materials can be firmly connected and fixed through the inner plate body. it can. If there is no inner plate but only the outer plate, the struck nail will loosen.

  Further, the connecting body has a ridge having a thickness substantially the same as the distance between the outer plate body and the inner plate body, and has a concave groove having a distance substantially the same as the thickness of the inner plate body. It is made of a material that is difficult to deform, and is joined to the outer edge of the plate material. As a result, the ridge of the connecting body is pushed between the outer plate body and the inner plate body, the inner plate body is pushed into the concave groove between the ridges of the connecting body, and the connecting body and the decorative plate are firmly attached. It is fixed to the link.

(1) Structure (plate structure) of decorative board 1 (plate material)
1 and 2 show an example of a decorative board 1 as a plate material, and shows a structure (plate structure) of the decorative board 1. The outer plate bodies 2 and 2 are substantially flat and are made of two substantially parallel materials that are not easily deformed. For example, the outer plate bodies 2 and 2 are made of wood or plywood. The thickness is several mm, desirably 1 to 5 mm, for example 2 to 4 mm, and is not easily deformed.

  The inner plate 3 is also substantially flat and is made of one or a plurality of substantially parallel materials that are difficult to deform, for example, wood or plywood. The thickness is several mm, desirably 1 to 5 mm, for example 2 to 4 mm, and is not easily deformed. The inner plate 3 is substantially parallel to the outer plates 2 and 2, and the two outer plates Located between the bodies 2 and 2.

  Interposition sheets 4 and 4 are interposed between the outer plate bodies 2 and 2 and the inner plate body 3. The intervening sheets 4 and 4 have a honeycomb structure in which a large number of thin corrugated paper sheets having a substantially constant width are erected and arranged in a zigzag manner to form a hexagonal shape and have a large number of cavities. The thin long cardboard paper has a thickness of several mm, for example, 1 to 3 mm, a width of several tens to several mm, for example, 5 to 10 mm, and the width is larger than the thickness.

  The intervening sheet 4 is thicker than the outer plate bodies 2, 2 and / or the inner plate body 3, and the inner plate body 3 has substantially the same thickness as the outer plate bodies 2, 2. Adhesive or the like is applied to one side surface of the intervening sheets 4 and 4, and is crimped to the inner surface of the outer plate member 2, and adhesive or the like is also applied to the other side surface of the intervening sheet 4. The inner plate 3 is crimped to both side surfaces.

  In the case where there are a plurality of inner plate bodies 3, in addition to the above, an adhesive or the like is applied to one side surface of the interposition sheet 4 between the plurality of inner plate bodies 3. It is crimped to the inner surface of the plate body 3, and an adhesive or the like is again applied to the other side surface of the interposition sheet 4, and is crimped to both side surfaces of the other inner plate body 3.

  In this crimping, pressure is applied from above and below with a flat press or with a rolling roller. In this way, the interposition sheet 4 is integrally connected to the outer plate bodies 2 and 2 and the inner plate body 3. Since the thickness of the intervening sheet 4 is substantially constant, the outer plate bodies 2 and 2 and the inner plate body 3 are kept substantially parallel. A decorative paper 5 is adhered and adhered to the outside of the outer plate bodies 2 and 2 with an adhesive or the like. This decorative paper 5 is a paper sheet having a wood grain pattern, a single color, and other patterns.

  The outer plates 2 and 2 and the inner plate 3 are not deformable materials such as wood and plywood, but are deformed such as bamboo, hard resin, hard carbon, metal, glass, hard rubber, and mixtures / multilayer laminates thereof. Materials that are difficult to do may be used. The material of the intervening sheet 4 is a cardboard having a honeycomb structure, and is made of a material that is softer and more easily deformed than the outer plate bodies 2, 2 and the inner plate body 3.

  In addition to corrugated paper, the intervening sheet 4 is easily deformed such as soft resin, soft carbon, soft rubber, cardboard, cardboard, cotton, cloth, fiber, urethane, urethane foam, sponge, and mixtures / multilayer laminates thereof. The material may be used. In addition to the hexagonal honeycomb structure, the intervening sheet 4 has a rectangular grid structure, and the above-mentioned material is a pine pattern, a striped pattern, a polka dot pattern, a triangular interspersed pattern, and other interspersed patterns. It is difficult to be deformed by the pressure from the side, and easily deformed by the pressure from the side edge direction.

(2) Connecting tool 11
FIG. 3 shows a perspective view of the connector 11, FIGS. 4 and 5 show a cross section of the connector 11, FIG. 3 shows a “cross-section L-shape”, FIG. 4 shows a “cross-section”, and FIG. It is a “shape”. The connector 11 has an elongated square prism shape, and the square prism has an overall shape along the outer edges of the outer plates 2 and 2. Two rows of ridges 12, 12 that are long in the longitudinal direction protrude from the side surface of the elongated square prism. The thickness of the ridges 12, 12 is substantially the same as the gap between the outer plate bodies 2, 2 and the inner plate body 3.

  A concave groove 13 is formed between the two rows of ridges 12 and 12. The interval / width of the concave grooves 13 is substantially the same as the thickness of the inner plate 3. The concave groove 13 and the ridges 12 and 12 are formed on four side surfaces of the square prismatic connector 11, that is, in different directions / four equiangular directions, respectively.

  The outer edge of the inner plate body 3 is inserted into the concave groove 13, and the ridges 12, 12 are hit by a wooden mallet or the like in the gap between the inner plate body 3 and the outer plate bodies 2, 2. It is pushed in and inserted. Accordingly, the decorative plates 1 are firmly connected and fixed to the connector 11, and the decorative plates 1 are also firmly connected and fixed.

  In this insertion, an adhesive may be applied to the outer edges of the inner plate body 3 and the outer plate bodies 2 and 2 and the outer surfaces of the ridges 12 and 12 and the groove 13 of the connector 11. If the adhesive is not applied, the decorative plate 1 can be removed from the connector 11 and reused, which is useful for recycling and does not generate waste.

  The material of the connector 11 and the ridge 12 is made of a material that is not easily deformed, such as wood, bamboo, hard resin, hard carbon, metal, glass, hard rubber, and a mixture / multilayer laminate thereof. The outer plate bodies 2 and 2 and the inner plate body 3 are also made of a material that is not easily deformed, and the intervening sheet 4 is made of a material and a structure that are easily deformed from the side edge direction / outer edge direction as described above. ing.

  Therefore, the outer plate bodies 2 and 2 and the inner plate body 3 are not deformed even when the connecting tool 11 and the ridges 12 hit. However, when the ridge 12 is pushed into the gap between the inner plate body 3 and the outer plate bodies 2, 2, the intervening sheet 4 is easily deformed from the side edge direction / outer edge direction. 12, the interposition sheet 4 is deformed and pushed.

  In this case, the height of the outer edge of the inner plate body 3 and the height of the outer edges of the outer plate bodies 2 and 2 are the same, and the groove 13 of the connector 11 has the same depth as the bottom of the connector 11, that is, the outer surface of the square prism. That's it. As a result, when the outer edge of the inner plate body 3 comes into close contact with the bottom of the concave groove 13, the outer edges of the outer plate bodies 2 and 2 come into close contact with the outer side surface of the square prism of the connecting member 11, There is no gap between the outer plate bodies 2 and 2.

  Note that the recessed groove 13 may be deeper, or the height of the outer edge of the inner plate body 3 may be lower than the height of the outer plate bodies 2 and 2 with a margin. Thereby, even if there are some errors in the dimensions, the outer edges of the outer plate bodies 2 and 2 are exactly aligned with the outer side surfaces of the square prisms of the connector 11 and there is no gap, so that the appearance is good. The bottom of the groove 13 may be higher or deeper than the outer shape of the connector 11.

  The depth of the groove 13, that is, the height of the ridge 12 is substantially the same as the thickness of the connector 11, but may be larger or smaller than the thickness of the connector 11. When the height of the ridges 12 is large, the ridges 12 and 12 are hard to come off from the decorative plate 1 and become sturdy. If the height of the ridges 12 is small, the decorative panel can be easily disassembled.

  In the example of FIG. 4, the decorative plate 1 is connected in a “cross shape” around the connector 11, the decorative plate 1 is connected in different directions, and the plurality of decorative plates 1 are connected to each other by the connector 11. In FIG. 4, the decorative board 1 connected to the upper direction and the left direction is omitted. If one direction is omitted with respect to the four ridges 12 of the connector 11, the decorative board 1 is connected in a “T-shape” around the connector 11. Further, as shown in FIG. 5, if the two directions are omitted for the four-way protruding strips 12 of the connecting tool 11, the decorative board 1 is connected to the “L-shaped” or “I-shaped” with the connecting tool 11 as the center. The

  Furthermore, if the three directions are omitted for the four different ridges 12 of the connector 11, only one decorative plate 1 is connected to the connector 11. In this case, the ridge 12 and the groove 13 are formed only in one direction / set in the connector 11, and the connector 11 is connected to the outer edge of the decorative plate 1. The outer edge is covered with the connector 11.

  The decorative paper 15 is adhered and pasted with an adhesive or the like to the outer surface of the connector 11 where the ridges 12 are not formed. In addition, not only four directions from which the protruding item | line 12 differs in the outer surface of the coupling tool 11 may be formed in five different directions, six different directions, etc., and the decorative board 1 is connected to each direction.

6, 7, and 8 show a cross-section of the second embodiment of the coupler 11, FIG. 6 is a “cross-section T-shape”, FIG. 7 is a “cross-section L-shape”, and FIG. . In these embodiments, the outer dimensions of the connector 11 are substantially equal to the inner space between the outer plates 2 and 2, and the connector 11 can be completely covered with the outer plates 2 and 2. .

  In the example of “cross section T-shaped” in FIG. 6, the outer dimension of the connector 11 is substantially equal to the inner space between the outer plate bodies 2, 2, and is equal to the outer surface of the protrusions 12, 12 and the outer surface of the connector 11. I'm doing it. Among the decorative plates 1 connected in a T-shape, one outer plate body 2, 2 of the decorative plate 1 in the same direction extends to the center of the connector 11, and the other outer plate member 2, 2 Is shorter by the width of the connector 11, and the inner plate bodies 3 and 3 are the same length as the outer plate body 2 on the shorter side or slightly shorter.

  The outer plate bodies 2 and 2 and the inner plate body 3 of the remaining decorative plate 1 have substantially the same length. The outer plate bodies 2 and 2 are in contact with the outer sides of the shorter outer plate bodies 2 and 2 and are exactly aligned with no gap. The decorative plate 5 is not attached to the surface of the connector 11 without the ridges 12, and the surface of the connector 11 without the ridges 12 is also completely covered with the outer plate 2. Accordingly, the decorative paper 5 is not required on the outer surface of the connector 11 and the joint between the connector 11 and the decorative board 1 can be eliminated.

  In FIG. 6, the joining position of the top two outer plate bodies 2, 2 may be the center of the upper surface of the connector 11, the right end and the left end of the connector 11, or the middle from the right end to the left end.

  The edges of the outer plate bodies 2 and 2 are cut obliquely, and the oblique cut surfaces of the outer plate bodies 2 and 2 are joined to each other without a gap and connected in a state of being orthogonal to each other. Since the connector 11 is completely stored in the outer plates 2 and 2, the connector 11 can be covered with the outer plates 2 and 2. Accordingly, the decorative paper 5 is not required on the outer surface of the connector 11 and the joint between the connector 11 and the decorative board 1 can be eliminated.

  In the example of “I-shaped cross section” in FIG. 8, the external dimensions of the connector 11 are substantially equal to the inner space between the outer plate bodies 2, 2, and are equal to the outer surface of the ridges 12, 12 and the outer surface of the connector 11.
