FLOOR MATERIAL, FLOOR STRUCTURE AND EXTRACTION METHOD OF SOME FLOOR MATERIAL
PROBLEM TO BE SOLVED: To provide a floor material that facilitates extracting some floor material after construction.SOLUTION: A floor material 10 of the present embodiment includes a surface layer 3 and a base material layer 4. The floor material has a longitudinal groove 1 on the surface 10a of the surface layer 3, and has a disrupting back longitudinal groove 2a on the backside 10b. The disrupting back longitudinal groove 2a is formed so as to comply with longitudinal groove 1 at the position corresponding to the longitudinal groove 1 of the backside 10b side of the floor material 10. Also, a rigidity lowering back longitudinal groove 2b is provided between the disrupting back longitudinal groove 2a and the floor material side end 10c. When the bending strength measured on condition that the rigidity lowering back longitudinal groove 2b is not present between support points in the three-point bending test is B, and the bending strength measured on condition that the rigidity lowering back longitudinal groove 2b is present is B, R(=B/B) is 0.10-0.40.SELECTED DRAWING: Figure 2
【課題】施工後に一部の床材を容易に抜き取ることが可能な床材の提供。【解決手段】本実施形態の床材１０は、表面層３と基材層４を備えるものであり、表面層３の表面１０ａに縦溝１を、その裏面１０ｂに分断用裏縦溝２ａを有しており、分断用裏縦溝２ａは、床材１０の裏面１０ｂ側の縦溝１に対応する位置に、縦溝１に沿うように形成されており、また、分断用裏縦溝２ａと床材側端部１０ｃとの間に剛性低下用裏縦溝２ｂを有しており、三点曲げ試験における支持点間に剛性低下用裏縦溝２ｂがない条件で測定した曲げ強さをＢ０、剛性低下用裏縦溝２ｂがある条件で測定した曲げ強さをＢ１とするとき、Ｒｂ（＝Ｂ１／Ｂ０）が０．１０〜０．４０である。【選択図】 図２
