Abstract

PURPOSE:To improve strength and design feeling of a butting part and contrive an improvement in productivity, by fitting a recessed crosspiecelike material over a projected crosspiecelike material and a pattern where a recession of the same is fitted over a projection of the same is formed on the surface. CONSTITUTION:A fitting recessed part 3 and fitting projection 4 are formed respectively on butting end faces of one side and the other side crosspiecelike material 2a through cutting. Then crosspiecelike materials 2a, 2b obtained by fitting the fitting recessed parts 3 over the fitting projections 4 are collected, a collected intermediate product 5 is sliced and a sliced veneer A on the surface of which a pattern 1 where a recession is fitted over a projection is formed is obtained. Strength of a butting part can be made high and design feeling of the same also can be improved with the pattern where the recession is fitted over the projection, in the sliced veneer A formed like this.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a sliced veneer and a method for manufacturing the same, and more specifically, it improves the strength of the butt of sliced veneers in a dark place, enhances the sense of design, and improves productivity. This is related to the technology you are trying to improve.

[Prior art J] Conventionally, the sliced veneer A'' has a butt pattern 1 in which crosspieces 2 at 2 b are simply butted together, as shown in FIG.
9 appears. Such a sliced veneer A' is obtained by simply butting the crosspieces 21Lt 2 b, assembling these butted crosspieces 2a and 2b, and slicing this assembled intermediate product to obtain a sliced veneer A'. You get it.

[Issues to be solved by the inventionffi] However, since the sliced veneer A'' simply shows the butt pattern 1'', the appearance is monotonous, the sense of design is low, and the butt points are Its strength is also low, and cracks tend to occur in these areas.Also, the manufacturing method tends to lack the butt strength, making it easy for cracks to occur during slicing or storage after manufacturing. There was a problem that productivity was low due to the necessity of

The present invention was made in view of these problems.
The purpose is to provide a sliced veneer and a method for manufacturing the same that can increase the strength of the butt portions of the sliced veneers, enhance the sense of design, and increase productivity.

[Means for Solving the Fi Problem 1] The sliced veneer of the present invention is characterized in that a concave-convex pattern 1 in which cross-shaped members 2a and 2b are fitted in concave-convex shapes is formed on the surface.

In addition, in the method for manufacturing a sliced veneer, a fitting recess 3 is formed in the abutting end surface of one of the crosspieces 2a which has a thickness and length and is butt-connected, and a fitting recess 3 is formed in the butt end surface of the other crosspiece 2b. A mating protrusion 4 is formed, the mating concave part 3 and the mating protrusion 4 are fitted in a concave-convex manner, and the group of cross-shaped members 21Lt 2 b that have been fitted in a concave-convex manner are assembled, and the assembled intermediate product 5 is assembled.
The method is characterized in that a sliced veneer having an uneven pattern 1 formed on the surface is obtained by slicing the veneer.

[Function] In this way, by forming the uneven fitting pattern 1 on the surface in which the crosspieces 2a and 2b are fitted unevenly, the strength of the butt direct contact in the sliced veneer A is increased, and the uneven fitting pattern 1 is formed. This also enhances the sense of design.

In addition, a fitting recess 3 is formed in the abutting end face of one of the bar-like members 2a which has a thickness and length and is butt-connected, and a fitting protrusion 4 is formed in the butting end face of the other bar-like member 2b. , the fitting concave portion 3 and the fitting protrusion 4 are fitted in a concave-convex manner, so that the concave-convexly fitted crosspieces 2 a, 2 b
This increases the connection strength of the laminated intermediate product 5 to prevent cracks from occurring at the joints of the crosspieces 2 at 2 b when slicing the laminated intermediate product 5 to obtain the sliced veneer A. It is designed to prevent damage such as damage and improve productivity and product strength.

[Example 1 Embodiments of the present invention will be described in detail below based on the drawings.

As shown in FIG. 2, a fitting recess 3 is formed on the butted end surface of one of the crosspieces 2a having an appropriate thickness and length.
(not shown). A fitting protrusion 4 is formed on the abutting end surface of the other bar-shaped member 2b by cutting with a cutter.

Then, as shown in FIG. 3, the fitting recess 3 and the fitting protrusion 4 are fitted in a concave-convex manner, and a bar-shaped member 21Lt that is fitted in a concave-convex manner as shown in FIG.
2b are assembled as shown in FIG. 4, and the assembled intermediate product 5 is sliced with a slicing blade to obtain sliced veneer A as shown in FIG.

In this way, in the sliced veneer A, the bar-like members 2a,
Since the concave-convex fitting pattern 1 in which the convex-concave fitting pattern 1 of the sliced veneer 2b is formed on the surface, the strength of the abutting portion of the sliced veneer A is increased, and the concave-convex fitting pattern 1 also enhances the design.

In addition, a fitting recess 3 is formed on the abutting end surface of one of the crosspieces 2a which has a thickness and length and is butt-connected, and a fitting protrusion 4 is formed on the abutting end surface of the other crosspiece 21. The fitting recess 3 and the fitting protrusion 4 are fitted in a convex-concave manner, thereby increasing the connection strength of the cross-fitted crosspieces 2 at 2 b, and slicing the intermediate product 5 into single slices. In order to obtain plate A, it is possible to prevent cracks from occurring at the joints of the crosspieces 2 a and 2 b, and to prevent damage during product storage or construction (increasing productivity and product strength). It also enhances

In addition, as shown in FIG. 5(,), the shapes of the fitting recess 3 and the fitting protrusion 4 are shaped so that it is impossible to pull out the crosspiece 2 at 2 b in the longitudinal direction. By doing so, the connection strength can be further increased. Figure 5 (b
) shows still another embodiment.

In this way, the shape and form of the concave-convex fitting pattern 1 can be changed in various designs.

[Effects of the Invention] In short, the present invention has a concave-convex pattern in which the cross-shaped members are fitted in concave and convex shapes on the surface, thereby increasing the strength of the butt points in the sliced veneer, and creating a design impression with the concave-convex pattern. It has the advantage that it can also be increased.

Further, a fitting opening portion is formed on the butting end surface of one of the crosspieces having thickness and length and being butt-connected,
A fitting protrusion is formed on the abutting end surface of the other bar-shaped member,
Since the fitting recess and the fitting protrusion are fitted in a concave-convex manner, the #? It increases the bonding strength and prevents cracks from occurring at the connection points of the crosspieces when slicing the laminated intermediate product to obtain sliced veneers, and prevents damage during product storage or construction. This has the advantage of increasing productivity and product strength.
