の表面から雄実4の上面までの寸法及び突板2の表面から雌実5の上側開口縁までの寸法を目地溝3の深さ寸法と略同じに形成してあるので、目地溝3の深さ寸法と間隙6の深さ寸法(突板2の表面から雄実4の上面までの寸法)を略同じにすることができ、目地溝3と間隙6の区別をつきにくくすることができる。 Since the surface of is formed from dimensions and sliced ​​veneer second surface to the top surface of Omi 4 depth dimension substantially eyes Rift 3 dimensions to the upper opening edge of Mesumi 5 same depth eye Graben 3 it is (from sliced ​​veneer second surface dimension to the top surface of Omi 4) dimensions and depth of the gap 6 can be made substantially the same, and can be difficult to regard a distinction eyes graben 3 and gap 6. 従って床材Aの継ぎ目部分を目立たないようにすることができ、床の外観を向上させることができるのである。 Therefore it is possible to make inconspicuous the joint portion of the floor member A, it is possible to improve the appearance of the floor.

【0022】また上記床材Aは、雌実5の上側の部分を突板2と基板1の上から一層目の単板1aと基板1の上から二層目の単板1bとの三層で構成し、しかも突板2 Further the flooring A is the three layers of the veneer 1b of the second layer to the upper portion of Mesumi 5 from the top of the protruded plate 2 and veneer 1a and the substrate 1 of the first layer from the top of the substrate 1 configuration and, moreover veneer 2
の繊維方向と基板1の上から一層目の単板1aの繊維方向を略直交させると共に基板1の上から一層目の単板1 The fiber direction and the veneer 1 first layer from the top of the substrate 1 causes substantially perpendicular to the fiber direction of the first layer of veneer 1a from above the substrate 1
aの繊維方向と基板1の上から二層目の単板1bの繊維方向が略直交するように突板2と単板1aと単板1bを積層したので、繊維方向が交互に異なるように積層する三層で雌実5の上側の部分を形成することによって、突板2と基板1の上から二層目の単板1bで基板1の長辺と略平行にかかる力に対して雌実5の上側の部分を割れにくくすることができると共に、基板1の上から一層目の単板1aで基板1の短辺と略平行にかかる力に対して雌実5の上側の部分を割れにくくすることができ、突板2の表面から雌実5の上側開口縁までの寸法を上記従来例より小さくしても雌実5の上側の部分の強度を基板1 Since the fiber direction of a fiber direction and veneer 1b of the second layer from the top of the substrate 1 was laminated veneer 2 and single-plate 1a and the single-plate 1b so as to be substantially perpendicular, stacked so that the fibers in different directions alternately Mesumi 5 by forming the upper portion of Mesumi 5 in three layers, a single plate 1b of the second layer from the top of the protruded plate 2 and the substrate 1 with respect to the long side and according to substantially parallel the force of the substrate 1 to be it is possible to hardly crack the upper portion of and difficult to break the upper portion of Mesumi 5 single plate 1a of the first layer from the top of the substrate 1 with respect to the short side and according to substantially parallel the force of the substrate 1 it can, substrate strength of the upper portion of the well Mesumi 5 dimensions from the surface of the sliced ​​veneer 2 to the upper opening edge of Mesumi 5 is made smaller than the conventional example 1
の長辺と平行方向と基板1の短辺と平行方向のいずれの方向にも高くすることができる。 It can be higher in either direction of the long side parallel to the short side parallel to the direction of the substrate 1.

【0023】また上記床材Aは、目地溝3の側面や底面及び突板2の表面と同じ色に雄実4の上面及び傾斜面7、9を着色して形成してもよく、このことで目地溝3 Moreover the flooring A may be formed by coloring the upper surface and the inclined surface 7 and 9 of Omi 4 the same color as the side surface and bottom surface and veneer second surface of the eye Graben 3, in this eyes graben 3
と間隙6の区別が一層つきにくくなる。 Distinction of the gap 6 is not easily attached more and. さらに施工の際に隣接する床材Aの間に間隙6を設けることによって、 By providing a gap 6 between the flooring A adjacent in further construction,
床材Aが乾燥によって収縮して隣接する床材Aの間が若干広がったとしても、その広がりを目立たないようにすることができると共に、床材Aの含水率が上がって床材Aが若干伸びたとしても、間隙6の間隔及び雄実4の先端と雌実5の底面との間にできる隙間10で上記伸びを吸収することができ、隣接する床材A同士が突き上げ状態にならないようにすることができる。 Even though slightly increased between flooring A floor material A is adjacent to shrink by drying, it is possible to make inconspicuous the spread up moisture content of flooring A flooring A slight even elongation, in the gap 10 formed between the bottom surface of the tip and Mesumi 5 spacing of the gap 6 and Omi 4 can absorb the elongation, so that adjacent flooring a together does not become the state the push-up it can be.

【0024】上記床材Aにおいて、突板2と単板1aと単板1bと単板1cを含水率6〜15%の単板で形成すると、特に床暖房用床材として用いた場合に床材Aは含水率が低下することによって図6に示すように凸反りする。 [0024] In the flooring A, to form a sliced ​​veneer 2 and single-plate 1a and the single-plate 1b and single-plate 1c in veneer moisture content 6-15%, flooring particularly when used for the floor heating flooring a is convex warpage as shown in FIG. 6 by the moisture content is reduced. この凸反りは、基板1の裏面に防音用溝8を設けることで基板1の層間のバランスが崩れ、しかも基板1の上から三層目の単板1cの繊維方向を基板1の短辺と略平行にしたために、含水率の低下による単板1cの収縮が基板1に大きく影響して発生するものである。 The convex warpage balance between the layers of the substrate 1 is lost by providing sound insulation groove 8 on the rear surface of the substrate 1, moreover the short side of the fiber direction substrate 1 of single plate 1c of the third layer from the top of the substrate 1 for the substantially parallel, shrinkage of the veneer 1c due to the decrease in water content is to generate a great influence on the substrate 1.

【0025】そこで本発明の床材Aは、突板2を含水率15〜18%以下の湿式単板で形成すると共に単板1a [0025] Therefore flooring A of the present invention, single plate 1a to form a veneer 2 15 to 18% water content by the following wet veneer
乃至1cを含水率6%以下の乾式単板で形成するようにしてある。 Or 1c and is adapted to form a dry single plate of a water content of 6%. 湿式単板は乾式単板に10〜15g/尺2の水を散布してその後4〜6時間養生させて形成するものであり、含水率の低下によって乾式単板よりも大きく収縮するものである。 Wet veneer is to form by curing followed 4-6 hours if it is sprayed with water 10 to 15 g / scale 2 in dry single disc, is to shrink greater than the dry single plate by a reduction in water content . そしてこのように含水率の低下によって収縮しにくい乾式単板で単板1bを形成し、突板2 And forming a single plate 1b in a deflated hard dry single disc in this way by the decrease in water content, veneer 2
を含水率の低下によって乾式単板よりも大きく収縮する湿式単板で形成して基板1に突板2の収縮の影響を与えやすくし、さらに単板1aの繊維方向を基板1の短辺と略平行にして基板1に単板1aの収縮の影響を与えやすくすることによって、含水率の低下による単板1cの収縮を含水率の低下によって収縮しにくい単板1bで抑えると共に単板1cの収縮量と単板1a及び突板2の合計の収縮量を略同じ大きさにして単板1cの凸反りを単板1a及び突板2の凹反りで相殺することができ、床材A Formed using a wet veneer shrinks larger than dry single disc easily affect the shrinkage of the veneer 2 on the substrate 1 by a decrease in water content, still short sides substantially in the fiber direction of the veneer 1a substrate 1 by easily affect the parallel to the veneer 1a on the substrate 1 by shrinkage, shrinkage of the veneer 1c suppresses the shrinkage of the veneer 1c due to a reduction in water content in a deflated hard veneer 1b by a reduction in water content the amount and veneer 1a and a substantially convex warpage of veneer 1c in the same size of the shrinkage of the sum of the veneer 2 can be offset by Ri 凹反 veneer 1a and veneer 2, flooring a
を凸反りさせにくくすることができる。 It can be a hard to a convex warpage.
