DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for manufacturing a long press, in which a plurality of pieces of wood 4F2+ +
2+...The entire core material 13) is formed by adhering the entire part,
A plurality of core materials +31 +31... are arranged at a predetermined interval so that the outer surfaces of the wood pieces (1) face each other, and these are interposed and adhered between the upper plate (4) and the lower plate (5), By cutting the upper plate (4) and lower plate (5) along the length of the core material (3) between the core materials ra+ 13), a plurality of bases (6) are created, and then this base is A method for manufacturing long presses, which is characterized in that after applying a decorative board (force) to the outer surface of the book (6) to give a decorative finish, the original book (6) is cut diagonally across the entire length of the book (6) into two parts. This is related to.

In producing this kind of long press,
Publication No. 78 provides a method for its production. In other words, this thing is made by arranging narrow pieces of wood (9) with a rectangular cross section in parallel at predetermined intervals on one wide lower board (8a), h, and between the pieces of wood (9). Insert reinforcing wooden ends 00) of a predetermined size into the gaps at regular intervals (Fig. 1 (a)
1) Cover the soil with the top plate (8b) and attach it to each other, as shown in Figure 1(b).
, divide the wood piece (9) along the longitudinal direction of the center and cut it into #
: To make the individual principal (11) (Fig. 1 (C)), a decorative board 02 such as cypress is glued to the top, bottom, left and right sides of the principal 0υ (Fig. 1 (d)), thus obtained. The original tree aυ is divided diagonally (Fig. 1(e)) to obtain a long press as shown in Fig. 2. However, in this case, when creating the principal (11), the upper and lower plates (8a
) (8b) When cutting k, the piece of wood (9) must be cut together, and the cutting resistance of the saw becomes large, making it difficult to cut in an accurate straight line and making machining difficult.
Irregularities tend to occur on the cut surface of 9), and the irregularities appear on the decorative board (12) that is attached to this surface, resulting in a poor appearance. Furthermore, it is difficult to cut the piece of wood (9) along the center line with a straight line (11r), and the piece of wood (9) cut as shown in Figure 3(a). If the thickness is not constant and the piece of wood (9) that forms the lower side of the long press is thin, the installation strength will be weak when attaching the long press to the lintel (15) etc. by nailing it (116), as shown in Figure 3 (b) K. Therefore, the quality of the mounting strength lacked uniformity. Furthermore, in this product, a large number of pieces of wood (9) and wood ends (10) are individually made of plywood (8).
) There is a base mold to be arranged on top, which takes a lot of time and effort, and it is difficult to arrange these correctly on the axis of rotation, which deteriorates the structural accuracy of long presses.

The present invention #4 has been developed in view of the above points, and the purpose is to provide a method for manufacturing long presses that can be manufactured with high productivity, dimensional accuracy, and structural accuracy. be.

The present invention will be explained in detail below. First, as shown in FIG. 4(a), a plurality of long pieces of wood (17) fI force... which are arranged in parallel at predetermined regular intervals are sandwiched between the substrates 08H1a1 below -H. ) and the substrate (the 1 mark are made into pseudo-rocks.Long piece of wood 07) or the substrate (for the 1 mark, woodblocks, boards, plywood, laminated wood, etc. can be used.Next, the 4th
The substrate 0gI and the long piece of wood 0η are cut in the direction perpendicular to the longitudinal direction of the long piece of wood (17) as shown by the imaginary line in Figure (a), and the board (181 full length A pair of parallel pieces of wood I11 obtained by cutting into lengths +11 A long piece of wood (17)'!z Wood i 1 obtained by cutting into short pieces

) As shown in K, the lower plates (5) made of plywood etc. are arranged parallel to the soil with a predetermined constant gap between them, and the upper plates (4) made of plywood etc. are covered with the upper plates (4). Lower plate 15
) to form a pseudo-rock. Here each core material f3113
The gap between the holes is set to be slightly larger than the thickness of the saw blade. After this, as shown by the imaginary line in FIG. 4(c), the upper plate (4) and the lower plate (5) are attached along the longitudinal direction of the core material 13) at the gap position between each core material +31131. disconnect. At this time, it is only necessary to cut the bottom board (4) and the bottom board (5), so the sawing work can be done easily, and the left and right core materials (3) 13) can be sawed using the wood pieces 111111. By being guided, the upper plate (4) and lower plate (5) can be cut along an accurate straight line. In this way, Figure 4 (dl) and Figure 5 (b)
) You can obtain multiple copies of the principal amount (6) as shown in (6).

In the original (6), the cut ends of the upper plate 14) and lower plate (5) that protrude slightly outward from the outer surface of the wooden piece (1) (1) are cut with a planer, etc., and the upper plate (4) and the lower plate are It is best to finish the end face of (5) flush with the outer surface of the wooden piece (1) (1). Next, the four sides of this principal (6) are decorated with decorative plates, etc.
As shown in Figure 4 (8), the main body (6) is fully finished with a decorative finish, and the diagonal line containing the wood pieces mIr+i ( By cutting the main body (6) along its entire length in step 1), one piece of wood (Ill) has a small trapezoidal cross section, the other piece (1) has a large trapezoidal cross section, and the end (2) It is possible to obtain a long press as shown in FIG. 4(f) in which the cross section is cut into a trapezoidal shape.

The long press obtained in this way is shown in Figure 6 as a lintel (1
It can be fixed by nailing (16) onto the top of 1 with a piece of wood 11) on the lower side, but this long press is reinforced with wood ends (2) at appropriate places and has strong strength, and the wood ends (2
) are in the right place and are not provided over the entire length of the long press, so they can be transformed into @silk and are convenient to transport and handle. Decorative board (Since it is applied with force, it can be installed directly on the lintel (1ω) etc. at the construction site.

- As described in F, in the present invention, a plurality of wood ends are interposed and attached at predetermined intervals between a pair of parallel long pieces of wood to form a core material, and the outer surfaces of the pieces of wood face each other. In this way, a plurality of core materials are arranged at predetermined intervals and placed between the upper plate and the lower plate. Since multiple principal sheets are created by cutting, all that is required to create the principal sheets is to cut the upper and lower plates along the core material, making it possible to cut with less cutting resistance from the saw. In addition to being able to cut while being guided by the core material, it is possible to cut on an accurate straight line, and it is possible to perform processing with accurate dimensional accuracy. Since it is not cut in the longitudinal direction, the thickness of the upper and lower sides of the long press made of wood does not change.
The quality of the long press can be stabilized without the fear that the attachment strength of the long press due to the lower side will not be constant, and since the wood piece is not cut in this way, the surface of the wood piece is smooth and the decorative board can be beautifully applied to the surface of the wood piece. It can be attached to. Furthermore, since the core material, which has been integrated with the wood chips and wood ends, can be sandwiched and glued between the upper and lower boards, it is possible to glue the core material between the upper board and the lower board. In addition to reducing the effort required when inserting the wood between the upper board and the T, it is possible to achieve accurate results by inserting a small number of core materials between the upper board and the T-sama rather than a large number of pieces of wood or wood ends. The 1”P material can be glued between the upper and lower plates due to their parallel positioning, and even if there is an error in the parallel positional relationship of the core materials, the upper and lower plates can be cut at the gap between the core materials. Since the original is created using the same method, it is possible to obtain long presses with accurate dimensions regardless of the parallel positional relationship of the individual core materials.

Next, the present invention will be explained with reference to Examples and specific numerical values.
