Description

[Detailed Description of the Invention] [Industrial application] The present invention relates to a structure of a curved panel that forms a round surface such as furniture, partitions, and pillar enclosures.

[Prior Art] For example, a curved panel that constitutes a round corner of a sink, a curved partition, a circular enclosure of a pillar, etc. is conventionally formed by curving a large number of sliced veneers and stacking them into an arc shape. The laminated plywood of was used. However, laminated plywood generally has a drawback that it is heavy, and when left in a place of high temperature and high humidity, it tends to be deformed (returned) in a planar direction and its shape retention is not necessarily good.

[Means for Solving the Problems] The present invention is intended to solve the above problems, and a plurality of concave grooves having a depth up to the middle of the thickness of the wood board material are formed on one surface of the wood board material having a constant thickness. A plurality of similar grooves are formed in parallel so that a thin continuous portion remains between the other surface of the wood board material and the groove bottom, and The wood board material is curved in an arc shape so as to narrow the groove width of the groove and widen the groove width of the concave groove on the other surface, and a shape-retaining sheet-like member is attached to at least the inner reduced surface of the wood board material. It is a curved panel characterized by

[Embodiment] Next, an embodiment of the curved panel of the present invention will be described with reference to the drawings.

First, as shown in FIG. 1, a concave groove 2a having a depth up to the middle of the thickness of the wooden board 1 is formed on one surface of the wooden board 1 having a constant thickness.
2a are formed in parallel, and the same concave grooves 2b, 2b are formed on the other surface of the wooden board 1 so that a thin continuous portion 3 is left between the concave grooves 2a, 2a. Are drilled in parallel. These recessed grooves 2a, 2a ..., Recessed grooves 2b, 2b
Can be cut at a time by a rotary saw in which a plurality of disk-shaped saw blades are fixed to a rotary shaft at regular intervals. In this case, the concave grooves 2a, 2a ... Are formed deeper than the concave grooves 2b, 2b. Further, 4 is a solid portion left without forming the concave groove in the central portion of the wooden board material 1.

However, the wooden board 1 is curved in an arc shape so that the groove width of the concave grooves 2a, 2a ... On one surface of the wooden board material 1 is narrowed and the groove width of the concave grooves 2b, 2b. As shown in FIG. 2, a plurality of wood boards 1 are arranged side by side, and plywood 5 and 6 as a shape-retaining sheet member are attached to the inner narrowing surface and the outer widening surface thereof with an adhesive. In addition, the solid part 4
Since it is possible to temporarily fix the plywoods 5 and 6 by hitting a nail at the time of this attachment, it is preferable to leave such a solid portion 4 in the molding at the mounting site.

The curved panel constructed in this manner has an arc plate shape whose front surface and inner surface are respectively covered by plywoods 5 and 6, so that round surfaces such as furniture, partitions, and pillar enclosures can be produced. The plywoods 5 and 6 can have various surface patterns other than wood grain, and can be matched with the interior design.

Further, as the shape-retaining sheet member, in addition to the above-mentioned plywoods 5 and 6, paper having strong tension can be used.

As shown in FIG. 3, if the shape-retaining sheet member 7 is attached only to the inner narrowing surface of the wooden board 1 and the outer widening surface is left as it is, a vertical striped three-dimensional pattern can be expressed on the outer surface. .

In addition, in this curved panel, since the continuous groove is formed, the air permeability into the wooden board material 1 is improved, so that the drying becomes easy. When the groove is used as a building material, it reduces the weight and improves the heat insulating property.

In addition, since it has a concave groove and is curved, it does not have large internal stress unlike conventional laminated plywood, and therefore has excellent shape retention and can be deformed even in high temperature and high humidity environments. There are few advantages.

[Advantage of Invention] As described above, according to the present invention, it is possible to provide a lightweight curved panel, and its curvature can be freely set by the groove width,
This has the effect of making it possible to easily equip various furniture and building materials with an arcuate surface.
