Description

  The present invention relates to a surface layer material effectively using natural wood and a building material using the same.

  Conventionally, as construction wood, solid parts as shown in FIG. 9 (a), laminated wood as shown in FIG. 9 (b), and base materials as shown in FIG. Thick veneer material in which a thick veneer (grinding plate) 51 of about 3 mm or less is laminated on 50, and a thin protrusion plate 52 of about 0.25 mm to 1 mm is bonded to a plywood 53 as shown in FIG. As shown in FIG. 9 (e), a laminated sheet plywood, which is laminated by bonding a printing sheet 54 to a plywood 53, and the like, is used.

  On the other hand, as a low-cost warp-free, low-cost composite plate that can be used for interior panels around water, using low-quality hardwood chips with low utility value, a single plate is bonded to both sides of the compression composite. Has been proposed (see, for example, Patent Document 1).

JP 09-207272 A

  However, in the above-mentioned conventional example, the solid wood cut out from natural wood as shown in FIG. 9 (a) has natural design and good design, and even if the surface is damaged, it can be repaired by shaving. However, since it is difficult to align the grain, it is impossible to produce a large amount because the grain is difficult to arrange, and the cost is high because it is expensive. In addition, there is a problem that cracking is likely to occur due to drying, and it is not suitable for flooring for floor heating.

  In addition, a laminated material assembled by bonding end materials cut out from natural wood as shown in FIG. 9B can be repaired by shaving even if the surface is damaged, so that the original design can be maintained. Since the seam is exposed on the surface of the object, the design is inferior in that respect, and there is a design limitation that a seamless wide design cannot be achieved. In addition, it is difficult to match the colors of the laminated lumber, and there is a problem that the cost is not as high as that of solid wood.

  In addition, the thick single plate material as shown in FIG. 9 (c) is excellent in design that exhibits a natural feeling comparable to that of a solid material, and does not easily warp. However, since the material structure is a single material, it is cracked by drying. In addition, there is a problem that the thickness of the single plate (grind plate) 51 is increased by the thickness.

  In addition, the thin-ply veneer plywood as shown in FIG. 9 (d) is relatively mass-produced and is excellent in design in that it has a uniform grain, the design is wide in application range, and cracks due to drying are unlikely to occur. Although it is suitable for a flooring or the like, there is a problem that the protruding plate 52 is very thin and is easily damaged unless a protective coating is applied to the surface, and if the surface is damaged, the back plywood 53 is easily exposed, resulting in poor design.

  In addition, the sheet pasting material as shown in FIG. 9 (e) is inferior in design in that the color pattern is stable and the cost is low but there is no natural feeling. In many cases, the printed sheet 54 is not produced, and there is a problem that the entire sheet is forced to be replaced.

  In addition, the double-bonded plate material of Patent Document 1 is likely to crack due to drying depending on the material structure as in the case of the thick single plate material as shown in FIG. 9C, and the cost increases by the thick single plates on both surfaces. There is a problem.

  The present invention solves the above-mentioned problems, and the object of the present invention is to efficiently cut out the good design of natural solid wood from natural wood and discard the remaining solid wood cut out in the past. It is possible to provide a surface layer material and a building material using the surface material that can exhibit the same effect as a good design that exhibits the natural feeling of the original solid wood. When the surface of the board or the finished floor is viewed, it cannot be distinguished from the board shown in FIG. 9A in terms of design and performance (strength, hardness, digging, etc.) and FIG. It is intended to provide a surface material that is better in design and performance than the plate shown in a) and a building material using the same.

Surface layer material according to the present invention for achieving the above object, a first thin solid plate consisting of one sheet, and made of the same species as the first thin solid plate material in multiple layers, wherein the upper surface of the top layer And a second thin solid plate member to which the first thin solid plate member is bonded , and each layer of the second thin solid plate member includes a plurality of laminated members assembled at different densities. To do.

  Here, the same tree species uses tree species having substantially the same woody performance such as color and hardness. For example, timber with the same name cut from the same production area can be applied.

Also, building materials according to the present invention, the second thin solid plate material before Symbol Table layer material is characterized in that it is bonded on the base substrate.

  Here, as the base substrate, plywood, particle board, hard board (hard fiber board), MDF (Medium Density Fiber board), insulation boat (soft fiber board), or synthetic resin can be applied. .

MDF is made by steaming and defibrating wood chips to a fiber level, applying a synthetic resin adhesive to wood fibers formed by air flow, and then forming a processed density by hot compression 0.35 g / cm ³ ~ 0.8g / cm ³ wood material, which removes defects such as knots, cracks, and decay of wood, has a uniform structure, has no grain, and has little warpage and width / length deviation. The cost is low because it is excellent in properties and is suitable for finishing of curved surfaces and engraving.

  Particleboard, on the other hand, is made by crushing wood into small pieces and hot-pressing with an adhesive. It has the same properties as MDF, but has excellent heat insulation and sound insulation properties. Applicable. Originally, MDF and particleboard are manufactured instead of wood using waste materials such as lumber and plywood, and are cheaper than wood and superior in workability. It is often used for building materials.

According to the surface layer material of the present invention, the second thin solid plate material is manufactured by effectively using the remaining end materials after collecting the first thin solid plate material comprising one sheet, 1 of the thin solid sheet, by constructing the surface layer material by laminating a second thin solid plate material multiple condensed Naruhen is being assembled, the total thickness of the surface layer material made of natural solid plate Since the thickness of the substrate can be increased, the degree of freedom in design processing such as groove processing is increased in addition to the good design properties that give a natural feeling, and the groundwork is not exposed by the groove processing and the like, so that the design properties are excellent. In addition, an impregnation type finish of oil or the like is possible, and a surface layer material that exhibits a natural design without impairing the wood texture can be easily obtained.

  In addition, by producing the second thin solid board material by effectively using the end material from the natural log, the surface layer material can be efficiently produced without waste from the limited natural log, to protect the natural environment. Can also contribute to cost reduction.

Further, it is possible to assemble pieces of several to a direction of the grain for a bonded structure of the first thin solid plate to the second thin solid plate on which formed by assembled in horizontal and vertical directions. In this case the aspect By controlling the expansion and contraction in the direction, it is possible to obtain a surface material that hardly warps and does not crack even when dried. Even if the grain direction is the same direction, the second layer, which is the second thin solid plate material, is subdivided more than the first layer, which is the first thin solid plate material, Expansion and contraction can be suppressed as compared with the case of only a single layer, and it can be constructed to be strong against warping and cracking.

Further, since the second thin solid sheet comprises a plurality multiple layers of assembled pieces were assembled in, since the total thickness of the surface layer material made of solid plate material having a natural wood grain further it is possible thicker Furthermore, in addition to the good design that exhibits a natural feeling, the degree of freedom of design processing such as grooving is further increased, and since the groundwork is not exposed even in deep grooving, the design is further improved. In addition, an impregnation type finish of oil or the like is possible, and a surface layer material that exhibits a natural design without impairing the wood texture can be easily obtained.

  In addition, by making effective use of the end material coming from natural logs, the second thin solid plate material with multiple layers can be used to efficiently produce surface layer materials from limited natural logs without waste. End material with a large difference between the grain and color of the first thin solid board material can be arranged in the lower layer to achieve both effective use of the end material and good design, thereby protecting the natural environment This also contributes to further cost reduction.

In addition, since the second thin solid plate material has a structure in which a plurality of laminated pieces are assembled into a plurality of layers, and the first thin solid plate material is bonded to the second thin solid plate material, the second thin solid plate material is used. Of the second layer, the grain direction of one layer is easily different from the grain direction of the first layer, which is the first thin solid plate material. Furthermore, it can be made a surface layer material which is hard to crack.

In addition , each layer of the second thin solid plate material has a plurality of laminated pieces assembled at different densities, so that a smaller end material or an end material having a large difference from the grain or color of the first thin solid plate material is obtained. It can be used effectively, and it can be made a surface layer material that is more difficult to warp by further controlling expansion and contraction in the vertical and horizontal directions, and that is hard to crack even when dried.

Moreover, according to the building material which concerns on this invention, the surface material which exhibits a natural feeling on a base material can be decorated by adhere | attaching the 2nd thin solid board | plate material of the said surface material on a base material. In addition, the surface layer material has a structure in which the first and second thin solid plate materials are laminated so that the entire thickness of the surface layer material made of the solid plate material having a natural grain is thick, and in addition to the good design that exhibits a natural feeling, Even if the surface layer material is uncolored, pale, or bright, the base material is not seen through, so it is not easily affected by the color of the base material, and is easy to finish. The degree of freedom in design processing is increased, and since the base substrate is not exposed even by grooving or the like, the design is excellent.

  An embodiment of a surface layer material according to the present invention and a building material including the same will be described specifically with reference to the drawings. 1A and 1B are a perspective view and a cross-sectional view showing a configuration of a first embodiment of a building material to which a surface layer material according to the present invention is bonded, and FIG. 2 is a building material provided with the surface layer material according to the present invention. The exploded perspective view which shows the structure of 1st Embodiment of this, FIG. 3 (a), (b) is the perspective view and sectional drawing which show the structure of 2nd Embodiment of the building material which adhered the surface layer material which concerns on this invention, FIG. 4 is an exploded perspective view showing the configuration of the second embodiment of the building material provided with the surface material according to the present invention, and FIGS. 5A and 5B are the third of the building material to which the surface material according to the present invention is bonded. FIG. 6 is an exploded perspective view showing a configuration of a third embodiment of a building material provided with a surface layer material according to the present invention, and FIGS. 7A and 7B are books. FIG. 8 is a schematic diagram for comparing the state of grooving between the surface layer material according to the invention and the conventional surface layer material. FIG. 8 shows the first thin solid plate material and the second thin solid plate material from natural logs. Is a diagram illustrating an example of a site that collected.

1 to 6, reference numeral 1 denotes a surface layer material, which is made of the same tree species as the first thin solid plate material 2 made of natural wood and made of one piece in the longitudinal direction, and is also made of natural wood. and a second thin solid plate 3 where a plurality of condensing Naruhen in a first longitudinal direction of the thin solid plate 2 is assembled, the first thin solid plate on the second thin solid plate 3 2 Are integrally formed.

  Here, the same tree species uses tree species having substantially the same woody performance such as grain, color, and hardness. For example, timber with the same name cut from the same production area can be applied.

The second thin solid plate 3 is composed of a double several layers, each layer will be assembled a plurality of collecting Naruhen, each layer of the thin solid plate 3 wherein the second plurality of thin solid Board materials are assembled at different densities. For example, as shown in FIG. 6, assembly density of each assembly piece of the top layer 4 is bonded to the first thin solid plate 2 of the second thin solid plate 3, each assembly piece of the lower layer 5 than It can comprise so that it may become smaller than the assembly density of.

Further, for example, as shown in FIGS. 2, 4 and 6, the second top layer 4 of the thin solid plate 3 which is bonded to the first thin solid plate 2 is first thin solid plate 2 with the same color or select what end material of approximate color is assembled, the lower level layer 5 can be selected those gray color is assembled mixed.

Further, it is possible to place the first grain direction of the thin solid plate 2, the top layer 4 is bonded to the first thin solid plate 2 of the second thin solid plate 3 and a grain direction in the same direction.

  The layer thickness of the first thin solid plate material 2 is preferably 0.6 mm or more and 2 mm or less, more preferably 1 mm or more and 2 mm or less. The thickness of each layer of the second thin solid plate 3 is preferably 0.6 mm or more and 5 mm or less. In addition, it is advantageous in terms of cost if the layer thickness of the second thin solid plate material 3 is larger than the layer thickness of the first thin solid plate material 2.

Moreover, the 1st thin solid board | plate material 2 can also be made into the form which assembled the some assembly piece in the transversal direction (width direction), as shown in FIG.5 and FIG.6.

7 is a building material is obtained by bonding the bottom layer 5 of the second thin solid plate 3 of the surface material 1 on the base substrate 6. As the base substrate 6, plywood, particle board, hard board (hard fiber board), MDF (Medium Density Fiber board), insulation boat (soft fiber board), or synthetic resin can be applied. Moreover, as the building material 7, it can be applied to various building materials such as flooring such as flooring, counters, headboards, joinery frames, window frames, baseboards, waist walls, etc., other furniture, desks, tables, It is also possible to apply to various wood products such as art materials.

The second thin solid plate material 3 shown in FIGS. 1 and 2 is an example in which the grain direction is arranged along the grain direction of the first thin solid plate material 2, and the second thin solid plate material 2 shown in FIGS. thin Solid plate 3, grain direction of the top layer 4 are arranged in a direction (cross direction) crossing the first wood grain direction of the thin solid plate 2, grain direction of the lower layer 5 of the first thin solid plate 2 It is an example arrange | positioned along the grain direction. Thus, by arranging the upper and lower layers of the second thin solid plate material 3 alternately in the cross direction, it is possible to improve the anti-stretching performance and the anti-cracking performance due to drying.

  5 and 6 show an example in which a plurality of the first thin solid plate materials 2 of the surface layer material 1 are arranged and bonded in the short direction (width direction) of the base substrate 6. A plurality of surface layer materials 1 shown in FIGS. 1 to 6 can be bonded in the vertical direction and / or the short direction (width direction).

7 (a) is a diagram showing a state of a groove wall surface in the case where the grooves ranging from the first thin solid plate 2 of the surface layer member 1 to a depth reaching the uppermost layer 4 of the second thin solid plate 3 FIG. 7B is a view showing the state of the groove wall surface when groove processing is performed in the range from the protruding plate 52 to the plywood 53 of the conventional thin protruding plate material shown in FIG. 9D.

As shown in FIG. 7 (b), the conventional thin-projection decorative plywood shown in FIG. 9 (d) is different in color from the veneer 52, and the plywood 53 without wood is exposed and the design of the groove wall surface is significantly lowered. but, as shown in FIG. 7 (a), when the surface layer material 1 according to the present invention, the first thin solid plate 2, the top layer 4 and the shade is the same color or similar colors in the second thin solid plate 3 Since both can be made of natural wood, the groove wall surface can maintain a good design with a natural feeling.

  FIG. 8 is a view showing an example of a portion where the first thin solid plate material 2 and the second thin solid plate material 3 are collected from the natural log 8. The natural log 8 has a different grain direction depending on the part to be collected, and there are few parts from which a beautiful grain can be taken. Further, even in the same log 8, the hue varies depending on the part. Therefore, the portion a where the first thin solid plate material 2 having a uniform color, a fine grain and a single sheet in the longitudinal direction can be collected is rare.

  The remainder obtained by collecting the first thin solid plate material 2 becomes the portions b and c for collecting the end material that collects the second thin solid plate material 3. The second thin solid plate material 3 can be composed of a plurality of layers, and the thin solid plate material 5 in which the pieces collected from the end material portion c where the grain is not clean and the hue is not uniform and is chopped is second. The natural log 8 can be effectively used without waste by arranging it in the lower layer of the thin solid plate 3.

According to the above configuration, the second thin solid plate material 3 is obtained by collecting the first thin solid plate material 2 that is one piece from the natural log 8 in the longitudinal direction and collecting the remaining end materials effectively. to produce a thin solid plate 2 of the first, by the longitudinal direction a plurality of collecting Naruhen to constitute a surface material 1 and the second thin solid plate 3 are laminated, which is assembled, natural solid Since the overall thickness of the surface layer material 1 made of a plate material can be increased, the degree of freedom of design processing such as grooving is increased in addition to the good design that exhibits a natural feeling. Since it is not exposed, it is excellent in design. In addition, an impregnation type finish of oil or the like is possible, and the surface layer material 1 exhibiting a natural design without impairing the wood texture can be easily obtained.

  Further, by producing the second thin solid plate material 3 by effectively using the end material from the natural log 8, the surface layer material 1 can be efficiently produced from the limited natural log 8 without waste. It also contributes to environmental protection and can reduce costs.

In addition, since the first thin solid plate material 2 is bonded to the second thin solid plate material 3 in which a plurality of assembled pieces are assembled in the longitudinal direction, the direction of the grain can be changed to the vertical and horizontal directions. In this case, it is possible to obtain a surface layer material 1 that is difficult to warp by controlling expansion and contraction in the vertical and horizontal directions, and that does not easily crack even when dried. Moreover, even if the grain direction is the same direction, the second layer, which is the second thin solid plate material 3, is subdivided more than the first layer, which is the first thin solid plate material 2. As for the thing, expansion and contraction can be suppressed as compared with the case of only a single layer, and it can be constructed to be strong against warping and cracking.

Since the first thin solid plate member 2 is formed by assembling a plurality of assembled pieces in the short direction, a wide building material 7 can be obtained, and a wide design can be applied.

  Further, when the second thin solid plate material 3 in which a plurality of laminated pieces is assembled is formed into a plurality of layers, the entire thickness of the surface material 1 made of a solid plate material having a natural grain can be further increased. Therefore, in addition to the good design that exhibits a natural feeling, the degree of freedom of design processing such as grooving is further increased, and the base material 6 is not exposed even in deep grooving, and thus the design is further excellent. In addition, an impregnation type finish of oil or the like is possible, and the surface layer material 1 exhibiting a natural design without impairing the wood texture can be easily obtained.

  In addition, the surface layer material 1 can be efficiently manufactured without waste from the limited natural log 8 by manufacturing the second thin solid plate material 3 having a plurality of layers by effectively using the end material from the natural log 8. It is possible to balance the effective use of the mill ends and the good design by arranging the lower mill ends and the end sections that have a large difference with the grain and color of the first thin solid plate 2 in the lower layer. This contributes to the protection of the natural environment and can further reduce costs.

Further, a plurality of the second thin solid plate 3 which collecting Naruhen is assembled as a plurality of layers, first on a thin solid plate 3 of the second is for the second adhesive structure thin solid plate 2 Since the grain direction of one layer of the second layer, which is the thin solid plate material 3, is easily different from the grain direction of the first layer, which is the first thin solid plate material 2, the warping is further controlled by further controlling expansion and contraction in the vertical and horizontal directions. It is difficult to form the surface material 1 which is hard to crack even when dried.

Further, each layer of the second thin solid plate 3 has a plurality of assembled pieces assembled at different densities, so that there is a large difference between the smaller end material and the grain and color of the first thin solid plate 2. The end material can be used effectively, and the surface layer material 1 can be made more difficult to warp by further controlling the expansion and contraction in the vertical and horizontal directions, and further difficult to crack even when dried.

Further, assembly density of each assembly piece of the top layer 4 is bonded to the first thin solid plate 2 of the second thin solid plate 3 is smaller than the assembly density of each assembly piece of the lower level layer 5, Smaller end materials can be used effectively by arranging smaller end materials and end materials having a large difference in grain and color of the first thin solid plate material 2 in the lower layer.

Further, the uppermost layer 4 of the second thin solid plate 3, that has a first thin solid plate 2 and the same color or similar colors, the surface layer material 1 which layers unchanged shade of the groove wall surface even when grooving Since it is difficult to be noticeable, it is possible to maintain a design with a natural feeling.

Further, by the first grain direction of the thin solid plate 2, the grain direction of the top layer 4 is bonded to the first thin solid plate 2 of the second thin solid plate 3 is arranged in the same direction, Since the grain directions of the first and second thin solid plate materials 2 and 3 are aligned, the surface layer material 1 that is laminated without changing the grain direction of the groove wall surface even when the grooves are processed is not noticeable. Can be maintained.

  Even if the first layer, which is the first thin solid plate material 2, can be seen through the second layer, which is the second thin solid plate material 3, the grain direction is the same, so it is difficult to determine whether the two are bonded or not. Therefore, the first layer, which is the first thin solid plate material 2, can be made thin, and therefore the second layer, which is the second thin solid plate material 3, can be made into a thick surface layer material. In terms of appearance, it looks like a single plate and is excellent in design.

The lower level layer 5 of the second thin solid plate 3, when the shading color is assembled with mixed, the uppermost layer 4 of the second thin solid plate 3, first a thin solid plate 2 as the same color or similar colors, while maintaining the design of exhibiting natural feeling since it is difficult that is noticeable is the surface material 1 formed by laminating unchanged shade of the groove wall surface even when grooving, the subordinate layer 5, a shading color By mixing them together, mill ends can be used effectively, contributing to the protection of the natural environment and reducing costs. Further, the size of each assembled piece of the thin solid plate material can be more effectively utilized by reducing the size of each assembled piece in the lower layer.

  Further, when the layer thickness of the first thin solid plate material 2 is set to 0.6 mm or more and 2 mm or less, a larger amount of the first thin solid plate material 2 exhibiting a natural feeling is collected from the natural log 8. I can do it. In addition, when the thickness of each layer of the second thin solid plate 3 is set to 0.6 mm or more and 5 mm or less, the remaining end after the first thin solid plate 2 is collected from the natural log 8. The second thin solid plate material 3 can be collected more from the material, and the surface material 1 can be efficiently and efficiently produced from the limited natural log 8 by laminating them. The overall thickness of the surface layer material 1 made of a solid plate material having a natural grain can be increased by the above, in addition to the good design that exhibits a natural feeling, the base substrate 6 is not seen through, The degree of freedom of design processing such as grooving is increased, and since the base substrate 6 is not exposed even by grooving or the like, the design is excellent. In addition, an impregnation type finish of oil or the like is possible, and the surface layer material 1 exhibiting a natural design without impairing the wood texture can be easily obtained.

  Further, by adhering the second thin solid plate material 3 of the surface layer material 1 onto the base substrate 6, the surface layer material 1 exhibiting a natural feeling can be decorated on the base substrate 6, and the surface layer material 1 is 1. The thickness of the entire surface layer 1 made of a solid plate having a natural grain due to the structure in which the second thin solid plates 2 and 3 are laminated, and in addition to the good design that gives a natural feeling, Even if the material 1 is uncolored, pale, or bright, the underlying substrate 6 is not seen through, so it is not easily affected by the color of the underlying substrate 6 and is easy to finish and has a groove processing. The degree of freedom of design processing such as the above is increased, and since the base substrate 6 is not exposed even by groove processing or the like, the design is excellent.

  In addition, by arranging a plurality of the surface layer materials 1 in the longitudinal direction and / or the short direction of the base substrate 6 and bonding them, it is possible to decorate the large area surface material 1 that gives a natural feeling to the large area base substrate 6. I can do it.

  As an application example of the present invention, it is applied to various building materials such as a surface layer material effectively using natural wood and floor materials such as flooring, counters, headboards, joinery frames, window frames, baseboards, waist walls, etc. using the same. In addition, it can be widely applied to various wooden products such as furniture, desks, tables and art supplies.
