Description

本開示は、床材及び床材の製造方法に関する。 The present disclosure relates to a flooring material and a method for manufacturing the flooring material.

従来から、床に適した合板として、９ｍｍ厚、９４５ｍｍ×１８４０ｍｍサイズの針葉樹からなるフロア用合板が知られている。このフロア用合板をギャングソーによって、３１３ｍｍ×１８４０ｍｍサイズの合板に３分割している。そして、この３１３ｍｍ×１８４０ｍｍサイズの合板は、その表層部に、３１３ｍｍ×１８４０ｍｍサイズのＭＤＦ（中密度繊維板）からなる表面材が接着剤で接着され、プレス複合し、さらにその上に、化粧材を接着している。 Conventionally, as a plywood suitable for a floor, a floor plywood having a thickness of 9 mm and a size of 945 mm × 1840 mm has been known. This floor plywood is divided into three parts of 313 mm × 1840 mm size plywood by a gang saw. Then, in this 313 mm × 1840 mm size plywood, a surface material made of 313 mm × 1840 mm size MDF (medium density fiberboard) is adhered to the surface layer portion with an adhesive, press-composited, and further, a decorative material is applied. Is glued.

その後、長手方向一側面と短手方向一側面とに雄実を形成するとともに、長手方向他側面と短手方向他側面とに雌実を形成する床材としている（例えば、特許文献１）。 After that, it is used as a flooring material that forms male fruits on one side surface in the longitudinal direction and one side surface in the lateral direction, and also forms female fruits on the other side surface in the longitudinal direction and the other side surface in the lateral direction (for example, Patent Document 1).

特開２０１８−５３５５８号公報Japanese Unexamined Patent Publication No. 2018-53558

上述したフロア用合板を用いた床材は、実を形成することによって、雄実部分を除く表面部の短手方向の寸法は３０３ｍｍ程度となり、雄実部を除く表面部の長手方向の寸法は１８２０ｍｍ程度となる。 In the flooring material using the above-mentioned floor plywood, by forming fruits, the dimension of the surface portion excluding the male fruit portion in the lateral direction is about 303 mm, and the dimension of the surface portion excluding the male fruit portion in the longitudinal direction is about 303 mm. It will be about 1820 mm.

近年、フロア用合板よりも、更に安価で流通量が多い普通合板を使用することが検討されつつある。この普通合板は様々な厚み、サイズのものが存在するが、上述したフロア用合板と近いサイズのものとしては、９１０ｍｍ×１８２０ｍｍサイズのものが流通している。しかし、この普通合板を均等に３分割した場合、切断刃によって短手方向の長さは、３０１ｍｍ〜３０２ｍｍになり、この普通合板をフロア用合板の代わりにそのまま使用することはできなかった。 In recent years, it has been considered to use ordinary plywood, which is cheaper and has a larger distribution volume than floor plywood. There are various thicknesses and sizes of this ordinary plywood, but as a size close to the above-mentioned floor plywood, a size of 910 mm × 1820 mm is on the market. However, when this ordinary plywood was evenly divided into three parts, the length in the lateral direction was 301 mm to 302 mm due to the cutting blade, and this ordinary plywood could not be used as it was in place of the floor plywood.

As shown in FIG. 2, the first dimension adjusting portion 121 and the second dimension adjusting portion 122 are formed from both end portions along the longitudinal direction of the covering portion 120 to both end portions 110 along the longitudinal direction of the second base material 11. It extends along 111. The first dimension adjusting portion 121 is in contact with the first side end portion 110 which is one end along the longitudinal direction of the second base material 11, and the second dimension adjusting portion 122 is in the longitudinal direction of the second base material 11. It comes into contact with the second side end portion 111, which is the other side end portion along the above.

第１寸法調整部１２１、及び第２寸法調整部１２２は、寸法調整材１２を第２基材１１に取り付けた際に、第１寸法調整部１２１及び第２寸法調整部１２２の先端が、第２基材１１の裏面と面一になる寸法が好ましい。また、被覆部１２０、第１寸法調整部１２１、第２寸法調整部１２２は、熱可塑性樹脂を押し出し成型することによって、一体となるように形成されることが好ましい。 In the first dimensional adjustment unit 121 and the second dimensional adjustment unit 122, when the dimensional adjustment material 12 is attached to the second base material 11, the tips of the first dimensional adjustment unit 121 and the second dimensional adjustment unit 122 become second. 2 It is preferable that the base material 11 is flush with the back surface. Further, it is preferable that the covering portion 120, the first dimension adjusting portion 121, and the second dimension adjusting portion 122 are integrally formed by extruding a thermoplastic resin.

被覆部１２０は、第２基材１１の表面部に接着剤などで接着されている。第１寸法調整部１２１、及び第２寸法調整部１２２は、第２基材１１の両側端部１１０、１１１に接着剤などで接着されている。接着剤としては、ソフトラッピングに適した接着剤であることが好ましく、ウレタン系の溶剤系接着剤や、反応性ホットメルト接着剤が好適である。接着剤の塗布量は、通常１０ｇ／ｍ²〜１００ｇ／ｍ²（乾燥時）程度であり、加工状態に応じて調整することができる。 The covering portion 120 is adhered to the surface portion of the second base material 11 with an adhesive or the like. The first dimensional adjustment unit 121 and the second dimensional adjustment unit 122 are adhered to both side end portions 110 and 111 of the second base material 11 with an adhesive or the like. The adhesive is preferably an adhesive suitable for soft wrapping, and a urethane-based solvent-based adhesive or a reactive hot-melt adhesive is suitable. The amount of the adhesive applied is usually about 10 g / m ^{2 to} 100 ^{g / m 2} (when dried), and can be adjusted according to the processing state.

第２基材１１の短手方向の寸法が３０２ｍｍであった場合、第１寸法調整部１２１、及び第２寸法調整部１２２の厚さ寸法（第２基材１１における短手方向の長さ寸法）は、それぞれ０．５ｍｍであることが好ましい。こうした構造をとることによって、第２基材１１の短手方向の寸法、第１寸法調整部１２１、及び第２寸法調整部１２２の厚さ寸法（第２基材１１における短手方向の長さ寸法）の合計が３０３ｍｍとなり、一般的な床材１の短手方向の長さと同じにすることができる。 When the dimension of the second base material 11 in the lateral direction is 302 mm, the thickness dimension of the first dimension adjusting portion 121 and the second dimension adjusting portion 122 (the length dimension of the second base material 11 in the lateral direction). ) Are preferably 0.5 mm, respectively. By adopting such a structure, the dimension of the second base material 11 in the lateral direction, the thickness dimension of the first dimension adjusting portion 121, and the second dimension adjusting portion 122 (the length of the second base material 11 in the lateral direction). The total of the dimensions) is 303 mm, which can be the same as the length of the general flooring material 1 in the lateral direction.

なお、第２基材１１の短手方向の長さが３０２ｍｍよりも短い場合は、第２基材１１の短手方向の寸法、第１寸法調整部１２１、及び第２寸法調整部１２２の厚さ寸法（第２基材１１における短手方向の長さ寸法）の合計が３０３ｍｍとなるように、更に、寸法調整部１２１、１２２の厚さ寸法（第２基材１１における短手方向の長さ寸法）を長くして、第２基材１１の短手方向の寸法を調整すればよい。 When the length of the second base material 11 in the lateral direction is shorter than 302 mm, the dimensions of the second base material 11 in the lateral direction, the thickness of the first dimension adjusting portion 121, and the thickness of the second dimension adjusting portion 122.

第１突出部１００及び第２突出部１０１は、平面視Ｌ字状になるように露見している。 The first protruding portion 100 and the second protruding portion 101 are exposed so as to be L-shaped in a plan view.

第１寸法調整部１２１と第１基材１０の第１側端部１０２との間の寸法をａとし、第２
寸法調整部１２２と第１基材１０の第２側端部１０３との間の寸法をｂとすると、ａとｂの寸法は、隣合う床材１同士を接合させた際にａの部分が隣合う床材１のｂの部分に隠れて露見できないよう、ａ≦ｂであるのが望ましい。これは、ａ＞ｂであれば、隣合う床材１を接合させた際にａの部分が露見することとなり目隙となるからである。 Let a be the dimension between the first dimension adjusting portion 121 and the first side end portion 102 of the first base material 10, and the second
Assuming that the dimension between the dimension adjusting portion 122 and the second side end portion 103 of the first base material 10 is b, the dimensions of a and b are such that the portion a is when the adjacent flooring materials 1 are joined to each other. It is desirable that a ≦ b so that it is hidden behind the b portion of the adjacent floor material 1 and cannot be exposed. This is because if a> b, the portion a is exposed when the adjacent flooring materials 1 are joined, which provides a gap.

同様に、第２基材１１の第３側端部１１２と第１基材１０の第３側端部１０４との間の寸法をｃとし、第２基材１１の第４側端部１１３と第１基材１０の第４側端部１０５との間の寸法をｄとすると、ｃとｄの寸法は、隣合う床材１同士を接合させた際にｃの部分が隣合う床材１のｄの部分に隠れて露見できないよう、ｃ≦ｄであるのが望ましい。これは、ｃ＞ｄであれば、隣合う床材１を接合させた際にｃの部分が露見することとなり目隙となるからである。 Similarly, the dimension between the third side end 112 of the second base material 11 and the third side end 104 of the first base material 10 is c, and the fourth side end 113 of the second base material 11 Assuming that the dimension between the first base material 10 and the fourth side end portion 105 is d, the dimensions of c and d are the flooring materials 1 in which the c portions are adjacent to each other when the adjacent flooring materials 1 are joined to each other. It is desirable that c ≦ d so that it is hidden behind the d portion of the above and cannot be exposed. This is because if c> d, the portion c will be exposed when the adjacent flooring materials 1 are joined, resulting in a gap.

こうした構造をとることによって、合板を切削するようなアイジャクリ加工をする必要がないので、床材１を容易に製造できるとともに、木材の廃棄コストを削減することができる。 By adopting such a structure, it is not necessary to perform an eye-catching process such as cutting plywood, so that the flooring material 1 can be easily manufactured and the waste cost of wood can be reduced.

なお、実施の形態１では、長手方向の寸法が１８２０ｍｍの普通合板を使用しているが、１８２０ｍｍよりも長い場合でも適用できる。この場合は、１８２０ｍｍになるように切断して使用すればよい。 In the first embodiment, ordinary plywood having a longitudinal dimension of 1820 mm is used, but it can be applied even when it is longer than 1820 mm. In this case, it may be cut to 1820 mm and used.

また、実施の形態１では、短手方向の寸法が９１０ｍｍの普通合板を長手方向に沿って３分割して使用しているが、９１０ｍｍよりも短い場合でも適用できる。この場合は、実施の形態１同様に３分割すると短手方向の寸法は３０２ｍｍよりも短くなるが、寸法調整材１２の第１寸法調整部１２１、及び第２寸法調整部１２２の厚さを厚くして第２基材１１と合わせて３０３ｍｍとなるようにすれば良い。 Further, in the first embodiment, the ordinary plywood having a dimension in the lateral direction of 910 mm is divided into three parts along the longitudinal direction and used, but it can be applied even when it is shorter than 910 mm. In this case, the dimension in the lateral direction becomes shorter than 302 mm when divided into three as in the first embodiment, but the thickness of the first dimension adjusting portion 121 and the second dimension adjusting portion 122 of the dimension adjusting material 12 is increased. Then, the total length may be 303 mm together with the second base material 11.

また、実施の形態１では、厚さ寸法が４ｍｍの普通合板を使用しているが、３ｍｍや５ｍｍでも良い。これらの場合、寸法調整材１２の被覆部１２０と化粧材１３の厚みを適宜調整して床材１全体の厚さを１２ｍｍとすればよい。なお、床材１全体の厚さは必ずしも１２ｍｍに限らず１５ｍｍや１８ｍｍでも良く、これらの場合、第１基材１０と第２基材１１とを加えた厚みに寸法調整材１２の被覆部１２０と化粧材１３との厚みを加えて１５ｍｍや１８ｍｍになるように調整すれば良い。
（実施の形態１の床材１の製造方法）
図５に示すように、実施の形態１に係る床材１の製造方法は、次のような手順となっている。 Further, in the first embodiment, ordinary plywood having a thickness dimension of 4 mm is used, but 3 mm or 5 mm may be used. In these cases, the thickness of the covering portion 120 of the dimension adjusting material 12 and the decorative material 13 may be appropriately adjusted so that the thickness of the entire floor material 1 is 12 mm. The total thickness of the flooring material 1 is not necessarily limited to 12 mm, but may be 15 mm or 18 mm. In these cases, the thickness of the first base material 10 and the second base material 11 plus the covering portion 120 of the dimension adjusting material 12 And the thickness of the decorative material 13 may be added to adjust the thickness to 15 mm or 18 mm.
(Manufacturing method of flooring material 1 of the first embodiment)
As shown in FIG. 5, the method for manufacturing the flooring material 1 according to the first embodiment is as follows.

図５（ａ）及び（ｂ）に示すように、まず、長手方向の寸法が１８２０ｍｍ、短手方向の寸法が９１０ｍｍ、厚さ寸法が４ｍｍである普通合板を、長手方向に沿って略同一寸法形状となるように、ギャングソーなどにより３分割する。そのうちの２つで第１基材１０と、第２基材１１とを形成する。第１基材１０と第２基材１１との短手方向の寸法は、３０２ｍｍ程度となっている。 As shown in FIGS. 5A and 5B, first, ordinary plywood having a longitudinal dimension of 1820 mm, a lateral dimension of 910 mm, and a thickness dimension of 4 mm is substantially the same along the longitudinal direction. Divide into 3 parts with a gang saw or the like so that the shape is obtained. Two of them form the first base material 10 and the second base material 11. The dimensions of the first base material 10 and the second base material 11 in the lateral direction are about 302 mm.

なお、３分割した基材のうち残りの基材１５は、他で普通合板を３分割したうちの１つの基材と合わせて別の床材１を形成してもよい。 The remaining base material 15 of the three-divided base materials may be combined with one base material of the other ordinary plywood divided into three to form another flooring material 1.

次に、熱可塑性樹脂を押し出し成型などで逆Ｕ字状とし、長手方向の寸法が１８２０ｍｍの寸法調整材１２を形成する。寸法調整材１２の被覆部１２０の厚さ寸法は、化粧材１３の厚さ寸法が２ｍｍである場合は、２ｍｍであることが好ましい。なお、被覆部１２０の厚さ寸法は、化粧材１３の厚さ寸法が１ｍｍである場合は、３ｍｍであってもよく、床材１の厚さ寸法が１２ｍｍとなるように、厚さ寸法を調整することができる。第１寸法調
整部１２１及び第２寸法調整部１２２の先端は、第２基材１１の裏面と面一になる寸法が好ましい。 Next, the thermoplastic resin is extruded into an inverted U shape to form the dimension adjusting material 12 having a longitudinal dimension of 1820 mm. The thickness dimension of the covering portion 120 of the dimensional adjustment material 12 is preferably 2 mm when the thickness dimension of the decorative material 13 is 2 mm. The thickness dimension of the covering portion 120 may be 3 mm when the thickness dimension of the decorative material 13 is 1 mm, and the thickness dimension is set so that the thickness dimension of the flooring material 1 is 12 mm. Can be adjusted. It is preferable that the tips of the first dimension adjusting section 121 and the second dimension adjusting section 122 are flush with the back surface of the second base material 11.

図５（ｃ）及び（ｄ）に示すように、第２基材１１の表面部、及び両側端部（第１側端部１１０、第２側端部１１１）に、寸法調整材１２を接着剤などで取り付ける。 As shown in FIGS. 5 (c) and 5 (d), the dimension adjusting material 12 is adhered to the surface portion and both side end portions (first side end portion 110, second side end portion 111) of the second base material 11. Attach with an agent.

次に、図５（ｅ）及び（ｆ）に示すように、寸法調整材１２の被覆部１２０の表面部に、化粧材１３を接着剤などで取り付ける。 Next, as shown in FIGS. 5 (e) and 5 (f), the decorative material 13 is attached to the surface portion of the covering portion 120 of the dimension adjusting material 12 with an adhesive or the like.

次に、図５（ｇ）及び（ｈ）に示すように、第１基材１０が第２基材１１の第１側端部１１０、及び第３側端部１１２から突出するように、第１基材１０の表面部に第２基材１１を接着剤などで取り付ける。 Next, as shown in FIGS. 5 (g) and 5 (h), the first base material 10 protrudes from the first side end portion 110 and the third side end portion 112 of the second base material 11. The second base material 11 is attached to the surface portion of the first base material 10 with an adhesive or the like.

なお、第１基材１０の表面部には、第２基材１１を取り付けるための基準線が記入されてあってもよい。この場合、基準線は、第１基材１０の表面部の長手方向及び短手方向にＬ字状に記入され、この基準線は、第１基材１０に第２基材１１を取り付けた際に、図２に示すように、ａ≦ｂ、ｃ≦ｄになることが好ましい。 A reference line for attaching the second base material 11 may be written on the surface portion of the first base material 10. In this case, the reference line is drawn in an L shape in the longitudinal direction and the lateral direction of the surface portion of the first base material 10, and this reference line is when the second base material 11 is attached to the first base material 10. In addition, as shown in FIG. 2, it is preferable that a ≦ b and c ≦ d.

こうした構造をとることによって、隣合う床材１を接合させた際にａやｃの部分が露見せず目隙とならないからである。 This is because by adopting such a structure, when the adjacent flooring materials 1 are joined, the portions a and c are not exposed and do not become a gap.

また、床材１の各ａ、ｂ、ｃ、ｄ（図２参照）の寸法が略同じになることが好ましい。この場合、隣接する床材１同士間の隙間がなくなるので、床材１の接合強度を高めることができる。 Further, it is preferable that the dimensions of each of a, b, c and d (see FIG. 2) of the floor material 1 are substantially the same. In this case, since there is no gap between the adjacent floor materials 1, the joint strength of the floor materials 1 can be increased.

なお、床材１全体の厚さを１５ｍｍまたは１８ｍｍにする場合は、その厚さに応じた厚さ寸法の普通合板で第１基材１０及び第２基材１１を形成してもよく、特に限定されることはない。 When the total thickness of the flooring material 1 is 15 mm or 18 mm, the first base material 10 and the second base material 11 may be formed of ordinary plywood having a thickness dimension corresponding to the thickness, and in particular. There is no limitation.

また、基材は必ずしも普通合板によって形成されている必要はなく、例えば、短手方向の寸法が９１０ｍｍ、長手方向の寸法が１８２０ｍｍ、厚さ方向の寸法が５．０ｍｍの構造用合板から第１基材１０、第２基材１１を形成し、寸法調整材１２の被覆部１２０及び化粧材１３の厚みを調整して床材１全体の厚さを１２ｍｍとしてもよい。さらに、床材１全体の厚さを１５ｍｍまたは１８ｍｍにする場合は、更に厚い構造用合板から第１基材１０及び第２基材１１を形成してもよく、特に限定されることはない。 Further, the base material does not necessarily have to be formed of ordinary plywood, for example, the first structural plywood having a short dimension of 910 mm, a longitudinal dimension of 1820 mm, and a thickness direction of 5.0 mm. The base material 10 and the second base material 11 may be formed, and the thickness of the covering portion 120 and the decorative material 13 of the dimension adjusting material 12 may be adjusted so that the total thickness of the floor material 1 is 12 mm. Further, when the thickness of the entire floor material 1 is 15 mm or 18 mm, the first base material 10 and the second base material 11 may be formed from a thicker structural plywood, and the thickness is not particularly limited.

また、第１基材１０は、第２基材１１の第２側端部１１１、第４側端部１１３から突出して、第２基材１１の裏面部に取り付けられてもよい。さらに、第１基材１０は、第２基材１１の第１側端部１１０からのみ突出し、第２基材１１の第３側端部１１２及び第４側端部１１３から突出しないように第２基材１１の裏面部に取り付けられてもよい。また、第１基材１０は、第３側端部１１２からのみ突出し、第２基材１１の第１側端部１１０及び第２側端部１１１から突出しないように第２基材１１の裏面部に取り付けられてもよく、特に限定されることはない。
（実施の形態２）
実施の形態２の基本的な構成は、実施の形態１と略同じである。よって、同一箇所には同一符号を付して説明を省略し、異なる箇所のみの説明を行う。 Further, the first base material 10 may project from the second side end portion 111 and the fourth side end portion 113 of the second base material 11 and be attached to the back surface portion of the second base material 11. Further, the first base material 10 protrudes only from the first side end portion 110 of the second base material 11, and does not protrude from the third side end portion 112 and the fourth side end portion 113 of the second base material 11. 2 It may be attached to the back surface portion of the base material 11. Further, the first base material 10 projects only from the third side end portion 112, and does not protrude from the first side end portion 110 and the second side end portion 111 of the second base material 11, and the back surface of the second base material 11 does not protrude. It may be attached to a portion and is not particularly limited.
(Embodiment 2)
The basic configuration of the second embodiment is substantially the same as that of the first embodiment. Therefore, the same reference numerals are given to the same parts, the description thereof will be omitted, and only the different parts will be described.

図６は、実施の形態２に係る床材１を示す斜視図である。図６に示すように、第１基材１０は、さらに、第１基材１０と略同一寸法形状の第３基材１５の表面部に積層され、第３基材１５は、第２基材１１と平面視で略全体的に重なるように位置している。つまり、
第３基材１５は、第１基材１０を介して第２基材１１の略真下に位置している。 FIG. 6 is a perspective view showing the flooring material 1 according to the second embodiment. As shown in FIG. 6, the first base material 10 is further laminated on the surface portion of the third base material 15 having substantially the same dimensions and shape as the first base material 10, and the third base material 15 is the second base material. It is located so as to substantially overlap with 11 in a plan view. In other words
The third base material 15 is located substantially directly below the second base material 11 via the first base material 10.

第１基材１０は、接着剤により第３基材１５の表面部に取り付けられる。また、第１基材１０は、第３基材１５の表面部に圧着、加熱により固着されるようにしてもよく、特に限定されることはない。 The first base material 10 is attached to the surface portion of the third base material 15 with an adhesive. Further, the first base material 10 may be fixed to the surface portion of the third base material 15 by pressure bonding and heating, and is not particularly limited.

第１基材１０、第２基材１１、第３基材１５は、普通合板が長手方向に沿って略同一寸法で複数に分割されることによって形成されている。実施の形態２では、長手方向の寸法が１８２０ｍｍ、短手方向の寸法が９１０ｍｍ、厚さ寸法が３ｍｍである針葉樹からなる普通合板が長手方向に沿って略同一寸法で３分割されて、第１基材１０と第２基材１１と第３基材１５を形成している。ここで、実施の形態２では第１基材１０と第２基材１１と第３基材１５との短手方向の寸法はそれぞれ３０２ｍｍ程度となるが、必ずしもこれに限らず切断刃によって３００ｍｍ〜３０２ｍｍ程度になる。 The first base material 10, the second base material 11, and the third base material 15 are formed by dividing ordinary plywood into a plurality of pieces having substantially the same dimensions along the longitudinal direction. In the second embodiment, a normal plywood made of softwood having a longitudinal dimension of 1820 mm, a lateral dimension of 910 mm, and a thickness dimension of 3 mm is divided into three with substantially the same dimensions along the longitudinal direction, and the first The base material 10, the second base material 11, and the third base material 15 are formed. Here, in the second embodiment, the dimensions of the first base material 10, the second base material 11, and the third base material 15 in the lateral direction are each about 302 mm, but the dimensions are not necessarily limited to this and are 300 mm or more depending on the cutting blade. It will be about 302 mm.

第３基材１５は、図６に示すように、長手方向に沿う一方側の端部である第１側端部１５０と、長手方向に沿う他方側の端部である第２側端部１５１と、短手方向に沿う一方側の端部である第３側端部１５２と、短手方向に沿う他方側の端部である第４側端部１５３とを有する。 As shown in FIG. 6, the third base material 15 has a first side end portion 150 which is an end portion on one side along the longitudinal direction and a second side end portion 151 which is an end portion on the other side along the longitudinal direction. And a third side end portion 152 which is an end portion on one side along the lateral direction, and a fourth side end portion 153 which is an end portion on the other side along the lateral direction.

第１突出部１００、及び第２突出部１０１は、第２基材１１側から見た平面視も第３基材１５側から見た平面視もＬ字状となるように露見している。 The first protruding portion 100 and the second protruding portion 101 are exposed so as to be L-shaped in both the plan view seen from the second base material 11 side and the plan view seen from the third base material 15 side.

第１突出部１００は、平面視で、第３基材１５の第１側端部１５０から寸法ａと略同じ寸法だけ突出し、第２突出部１０１は、第３基材１５の第３側端部１５２から図２における寸法ｂと略同じ寸法だけ突出している。こうした構造をとることによって、第１突出部１００と第２突出部１０１が雄実となり、基材を切削することなく、床材１の雄実を形成することができる。 The first protruding portion 100 protrudes from the first side end portion 150 of the third base material 15 by substantially the same size as the dimension a in a plan view, and the second protruding portion 101 is the third side end of the third base material 15. It protrudes from the portion 152 by substantially the same dimension as the dimension b in FIG. By adopting such a structure, the first protruding portion 100 and the second protruding portion 101 become males, and the males of the flooring material 1 can be formed without cutting the base material.

第２基材１１及び第３基材１５の短手方向の他方側と第１基材１０とで形成される凹部１４が、平面視で第２基材の１１短手方向から突出する第１基材１０の突出寸法以上の深さ寸法になっている。凹部１４は、第１凹部１４０と、第２凹部１４１とで構成されている。 The recess 14 formed by the other side of the second base material 11 and the third base material 15 in the lateral direction and the first base material 10 protrudes from the eleven short side of the second base material in a plan view. The depth dimension is equal to or larger than the protruding dimension of the base material 10. The recess 14 is composed of a first recess 140 and a second recess 141.

第１凹部１４０は、第２基材１１の裏面部と、第１基材１０の第２側端部１０３と、第３基材１５の表面部とで形成されている空間であり、第２凹部１４１は、第２基材１１の裏面部と第１基材１０の第４側端部１０５と、第３基材１５の表面部とによって形成される空間である。こうした構造をとることによって、第１凹部１４０及び第２凹部１４１が雌実となるので、基材を切削することなく、床材１の雌実を形成することができる。 The first recess 140 is a space formed by a back surface portion of the second base material 11, a second side end portion 103 of the first base material 10, and a front surface portion of the third base material 15, and is a second space. The recess 141 is a space formed by the back surface portion of the second base material 11, the fourth side end portion 105 of the first base material 10, and the front surface portion of the third base material 15. By adopting such a structure, the first recess 140 and the second recess 141 become females, so that the females of the flooring material 1 can be formed without cutting the base material.

複数の床材１を接合する場合、床材１の第１凹部１４０に隣接する床材１の第１突出部１００が収容され、床材１の第２凹部１４１に隣接する床材１の第２突出部１０１が収容されて、複数の床材１が接合される。 When a plurality of flooring materials 1 are joined, the first protruding portion 100 of the flooring material 1 adjacent to the first concave portion 140 of the flooring material 1 is accommodated, and the first of the flooring material 1 adjacent to the second concave portion 141 of the flooring material 1. 2 The protruding portion 101 is accommodated, and a plurality of flooring materials 1 are joined.

こうした構造をとることによって、合板を切削することなく、容易に雄実と雌実を形成することができるとともに、複数の床材１を容易に連結することができる。 By adopting such a structure, male and female fruits can be easily formed without cutting the plywood, and a plurality of flooring materials 1 can be easily connected.

また、分割された３枚の基材を積層することによって、床材１の厚みを増加させることにより、厚さが薄くて床材１に利用できない普通合板であっても床材１にすることができる。例えば、実施の形態２の床材１において、厚さ３ｍｍの普通合板を使用することによって、第１基材１０と第２基材１１と第３基材１５とで９ｍｍ、寸法調整材１２と化粧材
１３とで３ｍｍとすることで、容易に一般的な床材の厚さである１２ｍｍにすることができる。
（実施の形態２の床材１の製造方法）
実施の形態２に係る床材１の製造方法は、次のような手順となっている。 Further, by increasing the thickness of the flooring material 1 by laminating the three divided base materials, even the ordinary plywood which is too thin to be used for the flooring material 1 can be made into the flooring material 1. Can be done. For example, in the flooring material 1 of the second embodiment, by using a normal plywood having a thickness of 3 mm, the first base material 10, the second base material 11, and the third base material 15 are 9 mm, and the dimension adjusting material 12 is used. By setting the thickness of the decorative material 13 to 3 mm, the thickness of the general flooring material can be easily set to 12 mm.
(Manufacturing method of flooring material 1 of the second embodiment)
The method for manufacturing the flooring material 1 according to the second embodiment is as follows.

まず、長手方向の寸法が１８２０ｍｍ、短手方向の寸法が９１０ｍｍ、厚さ寸法が３ｍｍである普通合板を、長手方向に沿って略同一寸法形状となるように、ギャングソーなどにより３分割する。実施の形態２では、分割された３つで第１基材１０と、第２基材１１と、第３基材１５とを形成する。第１基材１０と第２基材１１と第３基材１５との短手方向の寸法は、３０２ｍｍ程度となっている。 First, ordinary plywood having a longitudinal dimension of 1820 mm, a lateral dimension of 910 mm, and a thickness dimension of 3 mm is divided into three by a gang saw or the like so as to have substantially the same dimensional shape along the longitudinal direction. In the second embodiment, the first base material 10, the second base material 11, and the third base material 15 are formed by the three divided parts. The dimensions of the first base material 10, the second base material 11, and the third base material 15 in the lateral direction are about 302 mm.

次に、樹脂を押し出し成型などで逆Ｕ字状され、長手方向の寸法が１８２０ｍｍの寸法調整材１２を形成する。 Next, the resin is extruded into an inverted U shape to form a dimension adjusting material 12 having a longitudinal dimension of 1820 mm.

次に、第２基材１１の表面部、及び両側端部１１０、１１１に、寸法調整材１２を接着剤などで接着して取り付ける。 Next, the dimension adjusting material 12 is adhered to the surface portion of the second base material 11 and the both side end portions 110 and 111 with an adhesive or the like.

次に、寸法調整材１２の被覆部１２０の表面部に、化粧材１３を接着剤などで取り付けて積層する。 Next, the decorative material 13 is attached to the surface portion of the covering portion 120 of the dimension adjusting material 12 with an adhesive or the like and laminated.

次に、第１基材１０が、平面視で第２基材１１の短手方向における一方側の端部、及び長手方向の一方側の端部から突出するように、第１基材１０の表面部に第２基材１１を接着剤などで取り付ける。 Next, the first base material 10 is projected from one end in the lateral direction and one end in the longitudinal direction of the second base material 11 in a plan view. The second base material 11 is attached to the surface portion with an adhesive or the like.

次に、第３基材１５が、平面視で略全面が第２基材１１と平面視で重なるように、第１基材１０の裏面部に取り付ける。 Next, the third base material 15 is attached to the back surface portion of the first base material 10 so that substantially the entire surface of the third base material 15 overlaps the second base material 11 in a plan view.

こうした構造をとることによって、基材を切削する必要がなく、基材を積層するだけで、雄実と雌実を形成できる。また、入手が容易な材料で床材を製造することができる。 By adopting such a structure, it is not necessary to cut the base material, and male and female fruits can be formed only by laminating the base materials. In addition, the flooring material can be manufactured from easily available materials.

なお、第３基材１５の表面部に第１基材１０を取り付けてから、第１基材１０の表面部に、寸法調整材１２及び化粧材１３が取り付けられた第２基材１１を取り付けてもよく、床材１の製造方法の順番は、特に限定されることはない。 After the first base material 10 is attached to the surface portion of the third base material 15, the second base material 11 to which the dimension adjusting material 12 and the decorative material 13 are attached is attached to the surface portion of the first base material 10. The order of the manufacturing methods of the flooring material 1 is not particularly limited.

なお、床材１全体の厚さを１５ｍｍまたは１８ｍｍにする場合は、その厚さに応じた厚さ寸法の普通合板で、第１基材１０と第２基材１１と第３基材１５を形成してもよく、特に限定されることはない。 When the total thickness of the flooring material 1 is set to 15 mm or 18 mm, the first base material 10, the second base material 11, and the third base material 15 are made of ordinary plywood having a thickness dimension corresponding to the thickness. It may be formed and is not particularly limited.

また、第１基材１０の短手方向の寸法は、第２基材１１及び第３基材１５の短手方向の寸法よりも短くてもよい。こうした構造をとることによって、様々な短手方向の寸法である普通合板及び構造用合板で基材を形成しても、廃棄する木材の量を減少し、効率よく基材を作成するとこができる。
［変形例］
なお、普通合板は、短手方向の寸法が１２２０ｍｍのものを用いても良い。この場合、普通合板を４分割して基材を形成する。 Further, the dimensions of the first base material 10 in the lateral direction may be shorter than the dimensions of the second base material 11 and the third base material 15 in the lateral direction. By adopting such a structure, even if the base material is formed of ordinary plywood and structural plywood having various dimensions in the short direction, the amount of waste wood can be reduced and the base material can be efficiently prepared. ..
[Modification example]
