FIG. 2G is a plan view showing a state in which the polygonal veneer block shown in FIG. 2E is assembled by tongue and groove, and FIGS. 3 to 7 illustrate a polygonal veneer block formed using pieces of polygonal veneer of different shapes. Top view.

Hereinafter, for convenience of description, a plate member and a method for manufacturing the polygonal veneer according to the present invention regularly arranged around a veneer veneer formed by combining four hexagonal veneer pieces to form one hexagonal veneer block and arranging them continuously. Explain.

1 and 2A, a plate member in which the polygonal veneer according to the present invention is regularly arranged is cut into polygons so that a plurality of pieces of veneer 1a can be regularly combined, and then the pieces of the veneer of the cut polygon are fixed. The veneer sheet 3 bonded to each other by combining to have a pattern is used.

To this end, screening veneer to be used as a surface material among the woodcuts cut from solid wood is selected (101), and the selected veneer is cut into polygons that can be regularly combined (103). In this case, various shapes such as a pentagon, a ladder, a square, a hexagon, or an octagon may be selected as illustrated in FIGS. 2G to 7, and as shown in FIG. 6 if necessary. It can also be cut into a rhombus 27. The polygon veneer pieces (1a, 1b) thus produced are regularly combined according to a predetermined pattern and then bonded (105). The bonding method used here is a butt-joining method in which a thermosetting resin such as melamine resin or urea resin is applied to the bonding surface and then bonded, or a zig zag splicing method using a thermoplastic bonding yarn. , A taping bonding method using a tape, or the like can be used. These joining methods can be used mainly for dry veneer with a thickness of 0.2 mm or more. However, if the veneer is less dry and does not reach dryness or breaks well, kraft paper, impregnated paper or non-woven fabric may be placed. In addition, there is no limit to the natural veneer species (樹 사용될) that can be used for carving polygonal veneer, all species of veneer existing on the earth can be used, and all kinds of dyed veneer and laminated veneer can be used. Since the final size of the veneer sheet (3) made by joining the polygonal veneer pieces (1a, 1b) is the size of the base plate to be described later, the veneer sheet (3) that has not reached the size of the base plate is joined to each other in the horizontal and vertical directions To match the size of (107). The size of the board is 3 characters × 6 characters, 3 characters × 7 characters, 3 characters × 8 characters, 4 characters × 6 characters, 4 characters × 7 characters, 4 characters × 8 characters, 4 characters × 10 characters, 5 characters × Various sizes, such as 8 characters, 5 characters × 10 characters, can be selected.

1 and 2B, the veneer sheet 3 made by the method described above needs to be kraft paper 9 impregnated with a phenol resin, melamine resin, or the like as needed to reinforce the physical properties such as strength. At this time, between the resin impregnated paper (9) and the veneer sheet (3) is not only exhibit the adhesive force itself when hot pressing, but also inserts an adhesive film (7) that can prevent the penetration of the phenol resin to the veneer. It is preferable to use the film which impregnated thermosetting resin, such as resin which mixed melamine resin or an acrylic resin, melamine resin, etc. in thin paper as said adhesive film 7. An upper surface of the veneer sheet 3 may be further provided with a transparent surface protection film 5 to protect the veneer surface layer. To this end, the resin impregnated kraft paper (109), the adhesive film is produced (113), the surface protection film is prepared (111), and then the resin impregnated kraft paper (9), adhesive film, veneer from below The sheet and the surface protective film are sequentially laminated (115), hot press put, and then bonded (117), followed by cooling and curing (119) to obtain a resin impregnated paper backing veneer board.

Referring to FIGS. 1 and 2C, the resin-impregnated paper backing veneer board 11 made by the above-described process is bonded onto a base plate such as plywood or fiberboard, which is relatively thick and has high strength and hardness (121). . Figure 2d shows the finished large backing veneer veneer (15). As shown in FIG. 2D, the finished veneer veneer veneer board 15 is regularly arranged with a beautiful veneer pattern implemented by polygonal veneer pieces. Although the shape of the large backing veneer board 15 shown in FIG. 2D appears to be regular arrangement of five-pointed veneer patterns, the four five-membered veneer forms a hexagonal block. It is also.

1 and 2E, another feature of the present invention is a veneer veneer veneer board 15, in which a veneer sheet 3, an adhesive film 7, a resin impregnated paper 9, and a base 13 are combined. NC routers are used to cut tongues and grooves on the sides while cutting in regular blocks along the boundaries of veneer pieces (123). Within each polygonal veneer board block, four pieces of veneer 1a may be enclosed, as in FIG. 1G, two pieces of veneer 1b may be enclosed, as in FIG. A piece of veneer may be included.

Referring to FIG. 2F, a tongue a corresponds to a convex portion formed on a side surface of the polygonal veneer board 17, and a groove is joined to and coupled to the tongue b. Corresponds to

In the hexagonal veneer board blocks 17, 19, and 21 shown in Figs. 2G, 3, and 4, tongues a are formed on three consecutive surfaces, and grooves b are formed on the other three surfaces. In the square veneer board block 23 shown in Fig. 5, the tongue a is formed on two consecutive surfaces, and the groove b is formed on the other two surfaces.

In the pentagon wood veneer block 25 shown in FIG. 6 and the octagon wood veneer block 29 shown in FIG. 7, when these are assembled, a mismatch gap exists between each block, as shown. The mismatch gap between the veneer board blocks 25 is filled with a rhombus block 27 consisting of one rhombic veneer piece, and the mismatch gap between the octagonal block 29 is a square block consisting of one square piece of wood veneer. Filling with (31) is preferred. To this end, grooves b are formed on all sides of the pentagon wood veneer block 25 and the octagon wood veneer block 29, and the rhombic block 27 and the quadrangle block 31 filling the gap are formed. Tongues (a) are formed on all sides, and a bar-shaped coupling member (c) is formed on the groove (b) of the side where the pentagonal veneer board blocks 25 meet or the side where the octagonal veneer board blocks 29 meet. Is preferably inserted.

According to the present invention, it is possible not only to manufacture a veneer sheet having a very high form and texture while using a piece of veneer, but also to improve the physical properties (strength, hardness, water resistance, absorbency, heat resistance, chemical resistance, etc.) of the sheet. It has the effect of extending the life. In addition, according to the present invention, it is possible to use even a small braid veneer has an effect that can significantly increase the yield of veneer.
