BACKGROUND OF THE INVENTION The present invention relates to an improvement of a long-pressing base material, more specifically, it is easy to apply a thin veneer on the surface,
In addition, the present invention relates to a long press component base material which has less warp and can be easily attached as a product.

2. Description of the Related Art In recent years, useful resources that can be practically used for wood have been depleted with the strengthening of environmental protection, and good quality surface veneer cannot be obtained for plywood and laminated wood of Lauan, which was a representative of inexpensive wood resources. It is in the trend of coming. For this reason, even in long presses that are decoratively attached to a wall surface, it is very difficult to overlay (paste) a decorative thin veneer on the surface of plywood or laminated wood, and surface treatment with putty material is an urgent task.

[0003]

Therefore, as one means, a board is pasted on the entire surface of the plywood or the laminated wood. When the board is pasted on the surface of the plywood or the laminated wood, the plywood or the laminated wood is laminated. However, the warp is strongly generated due to water absorption, which is one of the biggest drawbacks of wood, and contraction and expansion resulting therefrom.

[0004]

The present invention is intended to prevent warpage caused by water absorption, which is the biggest drawback of wood, and contraction and expansion resulting from it, that is, a long press component base for stabilizing dimension. In the provision of wood.

The gist of the present invention is that the sum of the vertical cross-sectional areas of the plywood or the laminated wood is the sum of the vertical cross-sectional area of the plywood or the laminated wood made of lauan or the like on the lower or central part of the back surface of the substrate with the board attached to the surface. It is a long-pressing constituent base material in which a reinforcing rod for preventing warpage of a vertical cross-sectional area is attached in the longitudinal direction so as to have at least a magnification with respect to the vertical cross-sectional area so as not to make the warp noticeable. Next, the present invention will be described in detail with reference to the following embodiments with reference to the drawings.

[0006]

EXAMPLES Generally, when a board is pasted on the surface of a plywood or laminated wood, the warp becomes remarkable unless the thickness of the plywood or laminated wood is more than 5 times the thickness of the board. For example, as shown in FIG. 1, conventionally, unless the thickness of the plywood or the laminated member 2a is 5 times or more the thickness of the board 3a constituting the substrate 1a, the warp of long pressing in which the decorative thin veneer 5a is pasted on the surface of the substrate 1a. Is very noticeable.

The long-pressing base material of the present invention will be described with reference to FIGS. 2 to 6. First, 1 is a plywood or laminated wood 2 made of softwood or lauan wood or the like, and a board 3 attached to the surface of the laminated wood 2. Therefore, the sum of the vertical cross-sectional area of plywood or laminated wood 2 at the lower back surface (FIG. 3, FIG. 6) or the central portion (FIG. 2, FIG. 4, FIG. 5) of the substrate 1 is relative to the vertical cross-sectional area of the board 3. Magnification (5 times or more) that does not cause noticeable length warpage
A reinforcing rod 4 for preventing warpage having a vertical cross-sectional area is attached in the longitudinal direction. In addition, 5 is a thin veneer and 6 is a kamoi.

Now, when the long-pressed substrate 1 is a plywood or laminated wood 2 having a board 3 of about 3 m / m on the front surface and a back surface of about 5 to 9 m / m, unfortunately, the thickness ratio is 1: 3. There is even up to and there is a unilateral warp. Therefore, wood (reinforcing rod 4) is attached to the back surface of the substrate 1 in order to eliminate this balance, but if the height of the long press is 90 to 120 m / m, the vertical cross-sectional area is 5 × 90 to 9 × 120 (mm ² ). The wood (reinforcing rod 4) corresponding to about 2/3 of the above is required. Therefore 12-35
Considering a material thickness of m / m, it is necessary to stick a material (reinforcing rod 4) of about 12 × 25 to 35 × 21 m / m. It should be noted that the reinforcing rod 4 is made of a material similar to or nearly the same as the plywood or the laminated member 2, but if a material which is hard to cause lateral warp is selected, the warp prevention effect may be obtained even with a vertical cross sectional area of 5 times or less. When the reinforcing rod 4 is attached to the lower part of the back surface of the substrate 1, the reinforcing rod 4 is fixed to the upper surface of the kamoi 6 and the long press is attached, as shown in FIG.
Further, when the reinforcing rod 4 is attached to the center of the back surface of the substrate 1, as shown in FIG. 5, the reinforcing rod 4 is easily inserted into the insertion hole 8 provided in the wall 7 above the kamoi 6 as a guide. Nagamushi is attached to the wall 7 by the construction method.

Even in the case of the long press adhered to the wall 7, there is a fear that the warp may be peeled off until the initial adhesive strength becomes strong due to the large warp stress. Therefore, it is provided as a straight long press member having no warp as much as possible. There is a need.

[0010]

EFFECTS OF THE INVENTION Since the long-pressing base material of the present invention is constructed as described above, it is economical to attach a thin veneer on the surface without the need for groundwork repair work. In addition, it is possible to prevent the warpage caused by the water absorption of the wood and the contraction and expansion resulting from the water absorption, that is, the dimensional stabilization.
