WOODY FLOOR MATERIAL AND CONSTRUCTION METHOD THEREOF
To provide a woody floor material and a construction method thereof capable of preventing a rise or a step in a tongue-and-grooved joint part from being generated in the woody floor material even when the woody floor material is largely extended in a width direction in a highly wet environment.SOLUTION: A female tongue part 10 and a male tongue part 20 are formed in a woody floor material A. A female tongue recessed groove 15 is provided in the female tongue portion 10 by an upper projection 11 and a lower projection 18. A surface side corner of the upper projection 11 is chamfered to form an upward-inclined surface 12. A male tongue ridge 25 and a small projection part 21 are formed in the male tongue part 20. A downward-inclined surface 22 is formed on a lower surface of the small projection 21. A supplementary angle θm of a corner between a surface 2 of a plate material 1 and the upward-inclined surface 12 is the same as an angle θo between the downward-inclined surface 22 and the surface 2 of the plate material 1, or the supplementary angle θm is formed smaller than the angle θo, and a height Sm of the upward-inclined surface 12 is the same as a height So of the downward-inclined surface 22 from the surface 2 of the plate material 1, or the height Sm is formed larger than the height So.SELECTED DRAWING: Figure 3
【課題】高湿潤環境で木質系床材が幅方向に大きく伸びたとしても、実接合部分で持ち上がりや段差が木質系床材に生じないようにすること。【解決手段】木質系床材Ａには雌実部１０と雄実部２０が形成されている。雌実部１０には上側突条１１と下側突条１８とで雌実凹溝１５が設けられている。上側突条１１の表面側角部が面取りされて上向傾斜面１２が形成されている。雄実部２０には雄実突条２５と小突条部２１とが形成されている。小突条部２１の下面には下向傾斜面２２が形成されている。板材１の表面２と上向傾斜面１２との間の角の補角θｍが、下向傾斜面２２と板材１の表面２との間の角度θｏと同じ角度、又は前記補角θｍが前記角度θｏより小さく形成され、上向傾斜面１２の高さＳｍが、板材１の表面２からの下向傾斜面２２の高さＳｏと同じ、又は前記高さＳｍが前記高さＳｏより大きく形成されている。【選択図】図３
