利点がある。[Effects of the Invention] In summary, the present invention is characterized in that a wooden veneer is laminated on a wooden plywood obtained by laminating a plurality of wooden boards with different fiber directions, and a plurality of grooves are juxtaposed from the back side of the wooden plywood. In addition, since the bottom of the groove is located on the uppermost layer or the wooden plate immediately below the uppermost layer, the wood plywood has sufficient bending flexibility,
The wooden board where the deep end of the groove, which is the part that forms the groove bottom, is located because the length direction of the groove matches the fiber direction of the wooden board that forms the groove bottom because the familiarity with the floor base is good. It is easy to bend without the resistance of the fiber, and as a result, sufficient bending flexibility can be obtained on the wooden flooring material without any trouble, and it can be directly glued or nailed on the floor substrate. There is an advantage that the laying and construction can be easily performed without the need for the work.
又、溝は最上層の木板を除いて形成されるから、溝の
奥深端部が至る木板の上層には溝が形成されていなくて
繊維方向が異なる最上層の木板が位置する故、溝の奥深
端部が至る木板の折れ方向の応力に最上層の木板がその

亀裂を抑制し、それ故に、木質合板の表面側には亀裂が
発生し難くて、表層の木質化粧単板に亀裂が入るような
こともなく、表面意匠上の問題がなく、木質化粧単板へ
の亀裂の波及を防止するようにしたものである。Also, since the groove is formed excluding the uppermost wooden board, no groove is formed in the upper layer of the wooden board to which the deep end of the groove reaches, and the uppermost wooden board having a different fiber direction is located. The top layer of the wooden board strongly opposes the stress in the bending direction of the wooden board to which the deep end reaches, based on the fiber direction, and suppresses the cracks caused by the formation of grooves, and therefore, the cracks on the surface side of the woody plywood It is possible to prevent the occurrence of cracks in the wooden veneer veneer of the surface layer without any cracks, and to prevent the problem of surface design, and to prevent the propagation of cracks to the veneer veneer.

施工をより可能になすことができるという利点がある。In addition, since the soft material layer is laminated on the entire back surface of the wood plywood, the flexibility of forming the grooves improves the familiarity with the floor base, and the soft material layer includes a floor base such as mortar and concrete. There is an advantage that the closeness to the floor can be enhanced, the slip resistance to the floor substrate can be enhanced, and the laying work without using nails or the like can be made more possible.
又、長尺になされた木質合板の短尺方向に溝の長さ方
向が向けられるから、木質合板の長さ方向の一層の屈曲
柔軟性を高めることができるという利点がある。Further, since the length direction of the groove is directed to the short direction of the long wooden plywood, there is an advantage that the bending flexibility in the length direction of the wooden plywood can be further increased.
又、木質化粧単板の繊維方向と最上層の木板の繊維方
向とを一致させるから、木質化粧単板と最上層の木板と
の馴染み性を増し、溝が形成されていない最上層の木板

に抑制することができるという利点がある。In addition, since the fiber direction of the veneer veneer and the fiber direction of the uppermost veneer are matched, the familiarity between the veneer veneer and the uppermost veneer is increased, and the uppermost veneer without grooves is formed. In addition, there is an advantage that transmission of cracks and the like to the wooden veneer can be more sufficiently suppressed.
