床 材

Floor board

Abstract

PROBLEM TO BE SOLVED: To provide floor board, in which generation of widthwise warping like a valley can be prevented. SOLUTION: Decorative veneer 2 is bonded through non-rigid adhesive to the front surface of board 1 under the condition that the grain direction at the front surface of the board 1 is arranged to be parallel to the grain direction of the decorative veneer 2. Further, preliminarily pasted veneer 3 is bonded with rigid adhesive to the rear surface of the board 1 under the condition that the grain direction at the rear surface of the board 1 is arranged to cross the grain direction of the preliminarily pasted veneer 3. Since the bond strength between the board 1 and the decorative veneer 2 is not so strong that the influence of the decorative veneer 2 can be hard to transmit to the board 1 even when the decorative veneer 2 tends to valley-bend. By strongly fixing the board 1 to the preliminarily pasted veneer 3, the board 1 can be backed up by the preliminarily pasted veneer 3 even when the board 1 tends to valley-bend under the influence of the decorative veneer 2.
(57)【要約】 【課題】 巾方向に谷反りするのを防止することができ る床材を提供する。 【解決手段】 基板1の表面の木目方向と化粧単板2の 木目方向を平行方向に配置すると共に基板1の表面に化 粧単板2を軟質接着剤で接着する。基板1の裏面の木目 方向と捨て貼り単板3の木目方向を交差する方向に配置 すると共に基板1の裏面に捨て貼り単板3を硬質接着剤 で接着する。基板1と化粧単板2の接着強度がそれほど 大きくなく、よって化粧単板2が巾方向に谷反りしても その影響が基板1に伝わりにくくすることができる。基 板1に捨て貼り単板3を強固に固定して基板1が化粧単 板2の影響を受けて谷反りしようとしても捨て貼り単板 3で支持することができる。
