Description

本発明は、床材の製造方法に関する。   The present invention relates to a method for manufacturing a flooring.

従来、雄実部と雌実部を有した床材の床下地への固着のやり方は、両実部のいずれか一方に木ねじやビス、ステープルなどの固定具を打つことでなされることが通例となっている。したがって、床材を床下地にしっかりと、かつ確実に固着するためには、実部に、固定具が打てないほどの硬質な節や、節が抜けて空洞となった節抜け部、打ち付けた固定具が弛むほどの空隙が存在しないことが必要とされる。   Conventionally, the method of fixing a floor material having a male real part and a female real part to a floor base is usually performed by hitting a fixing tool such as a wood screw, a screw, or a staple on one of both real parts. It has become. Therefore, in order to firmly and securely fix the flooring to the floor base, the actual part is hard enough to prevent the fixing tool from hitting, or the part of the part that has been hollowed out, It is required that there are no gaps that allow the fixture to loosen.

このような点を鑑みて、実部を基材自体の材料では構成せずに、均質な材料よりなる別部材で構成することが種々提案されている（たとえば、特許文献１参照）。このような技術は、基材として節の多い針葉樹合板や空隙を有した木質繊維材を用いたものに特に有効である。   In view of such a point, various proposals have been made in which the real part is not formed of the material of the base material itself but is formed of another member made of a homogeneous material (for example, see Patent Document 1). Such a technique is particularly effective for a material using soft wood plywood with many nodes as a base material or a wood fiber material having voids.

特許文献１に記載の技術は、基材の一方の面において、端部には凹段部を形成し、端部間の中央部には凹溝部を形成し、凹段部と凹溝部に別部材を装着貼り付けし、凹溝部に埋め込んだ別部材の幅方向の中央で基材を切断して複数の床元材を形成するものである。この床元材は両側端に別部材が配された実部形成前のものであり、それぞれの側端部を切削加工（切除）することで、一方には雄実部が形成され、他方には雌実部が形成された床材が製造される。よって、この文献技術によれば、別部材で構成された雄実部、雌実部を有した床材を簡易に形成することができる。   In the technique described in Patent Document 1, a concave step portion is formed at one end of a base material, a concave groove portion is formed at a central portion between the end portions, and the concave step portion and the concave groove portion are separately provided. A member is mounted and pasted, and the base material is cut at the center in the width direction of another member embedded in the concave groove portion to form a plurality of floor base materials. This floor base material is the one before the real part formation in which separate members are arranged on both side ends. By cutting (removing) each side end part, the male real part is formed on one side, The floor material in which the female part is formed is manufactured. Therefore, according to this literature technique, the floor material which has the male real part and the female real part which were comprised by the separate member can be formed easily.

特開２００６−３７５２０号公報JP 2006-37520 A

ところで、上述したように、この種の床材を床下地に固定具止めする部位は雄実部、雌実部のうちの一方である。したがって、適正な固定具止めができる床材としては、いずれか一方の実部を固定具止め用実部として別部材で形成されていれば十分である。   By the way, as mentioned above, the site | part which fixes this kind of flooring to a floor base is one of a male real part and a female real part. Therefore, as a flooring material capable of appropriately fixing a fixture, it is sufficient that any one of the real parts is formed as a separate member for fixing fixtures.

しかしながら、上記文献の方法では、雄実部と雌実部の両方を別部材で形成しているため、必要以上の別部材が必要とされ、それらの装着貼り付け作業について多くの工数が必要とされる。また、一方のみの実部を形成するために基材の端部の凹段部に対して取りつける別部材と、両方の実部を形成するために凹溝部に対して取りつける別部材とでは当然に寸法が異なる。よって、床材を形成するために２種類の別部材を用意しなければならない。   However, in the method of the above-mentioned literature, both the male real part and the female real part are formed as separate members, so that separate members more than necessary are required, and a lot of man-hours are required for their mounting and pasting operations. Is done. Of course, another member that is attached to the concave step at the end of the base material to form only one real part and another member that is attached to the concave groove part to form both real parts. The dimensions are different. Therefore, two types of separate members must be prepared to form the flooring.

本発明は、このような事情を考慮して提案されたもので、その目的は、床下地に対してしっかりとした固定具止めをするための適切な実部を効率的に形成できる床材の製造方法を提供することにある。   The present invention has been proposed in view of such circumstances, and its purpose is to provide a flooring material that can efficiently form an appropriate real part for securing a fixed fixture to a floor base. It is to provide a manufacturing method.

上記目的を達成するために、本発明の床材の製造方法は、基材の短辺と長辺のそれぞれ１辺について、上下面のいずれか一方の角部を所定深さに切削して切り欠き凹所を形成し、前記切り欠き凹所に、その凹所空間の全体を埋めるように、かつ、面側において前記基材と略面一となるように形成した別部材を装着貼り付けし、前記基材の上面に表面材を貼り付け、装着貼り付けされた前記別部材の一部を切除して固定具止め用実部を形成し、かつ、該固定具止め用実部とは反対側となる辺において前記基材の一部を切除して非固定具止め用実部を形成することを特徴とする。   In order to achieve the above object, the floor material manufacturing method of the present invention cuts one corner of the upper and lower surfaces to a predetermined depth for each of the short side and the long side of the base material. A notch recess is formed, and another member formed so as to fill the entire recess space and to be substantially flush with the base material on the surface side is attached and pasted to the notch recess. A surface material is pasted on the upper surface of the base material, and a part of the attached member is cut off to form an actual part for fixing the fastener, and opposite to the actual part for fixing the fastener A part of the base material is cut off at a side to be a side to form a non-fixing-fixing real part.

本発明の床材の製造方法によれば、上述した手順となっているため、床下地に対してしっかりとした固定具止めをするための適切な実部を効率的に形成することができる。   According to the floor material manufacturing method of the present invention, the procedure described above is used, and therefore, an appropriate real part for firmly fixing the fixture to the floor base can be efficiently formed.

以下に、本発明の実施の形態について、添付図面をもとに説明する。まず、実施形態に共通する基本構成について概説する。   Embodiments of the present invention will be described below with reference to the accompanying drawings. First, a basic configuration common to the embodiments will be outlined.

以下に示した種々の実施形態に係る床材の製造方法は、つぎのような手順となっている（図１〜図４参照）。   The floor material manufacturing methods according to various embodiments shown below are as follows (see FIGS. 1 to 4).

まず、基材１０の短辺と長辺のそれぞれ１辺について、上下面のいずれか一方の角部１１を所定深さに切削して切り欠き凹所１２を形成する。
つぎに、切り欠き凹所１２に、その凹所空間の全体を埋めるように、かつ、面側において基材１０と略面一となるように形成した別部材２０を装着貼り付けする。
その後、基材１０の上面に表面材２５を貼り付ける。
ついで、装着貼り付けされた別部材２０の一部を切除して固定具止め用実部１を形成し、かつ、固定具止め用実部１とは反対側となる辺において基材１０の一部を切除して非固定具止め用実部２を形成する。 First, with respect to each of the short side and the long side of the base material 10, either one of the upper and lower corners 11 is cut to a predetermined depth to form the cutout recess 12.
Next, another member 20 formed so as to fill the entire recess space and to be substantially flush with the base material 10 on the surface side is attached and attached to the cutout recess 12.
Then, the surface material 25 is affixed on the upper surface of the base material 10.
Next, a part of the attached and pasted another member 20 is cut off to form the fixing member fixing actual part 1, and one side of the base material 10 on the side opposite to the fixing member fixing actual part 1. The part is excised to form the non-fixing tool stopper real part 2.

ここで、基材１０としては、無垢の木材、集成材、スギ、ヒノキ、カラマツ、トドマツなどの節の多い針葉樹合板、ＭＤＦ（中密度繊維板）、ＨＤＦ（高密度繊維板）、インシュレーションボード、ＯＳＢ（配向性ストランドボード）などが挙げられる。また、基材１０の厚みは９〜１５ｍｍ程度である。   Here, the base material 10 includes solid wood, laminated wood, cedar, cypress, larch, todomatsu, etc., softwood plywood, MDF (medium density fiberboard), HDF (high density fiberboard), insulation board And OSB (oriented strand board). Moreover, the thickness of the base material 10 is about 9-15 mm.

また、別部材２０としては、木材、合板、パーティクルボード、ＭＤＦ、ＨＤＦなどの木質ボードが挙げられる。別部材２０としてはさらに、ＡＢＳ（アクリロニトリル・ブタジエン・スチレン樹脂）、ＰＶＣ（ポリ塩化ビニル）、ＰＳ（ポリスチレン）などの樹脂材料が用いられる。また、別部材２０として、樹脂に木粉等のフィラーを添加したウッドプラスチック、樹脂に発泡剤を添加し成形した発泡樹脂材料などを用いることもできる。別部材２０には、節や空隙などの欠点がなく材料が均質であるものが用いられることが望ましい。   The separate member 20 may be a wood board such as wood, plywood, particle board, MDF, or HDF. As the separate member 20, a resin material such as ABS (acrylonitrile butadiene styrene resin), PVC (polyvinyl chloride), PS (polystyrene), or the like is further used. Further, as the separate member 20, a wood plastic in which a filler such as wood powder is added to a resin, a foamed resin material in which a foaming agent is added to a resin, and the like can be used. It is desirable that the separate member 20 be made of a material having no defects such as nodes and voids and having a uniform material.

つぎに、図１および図２に示した、床材の製造方法について詳細に説明する。なお、図１の各図は製造方法を床材の概略縦断面図で示したものであり、図２の各図は製造方法を床材の概略平面図で示したものである。なお、床材の仕上げの平面寸法は３０３ｍｍ×１８１８ｍｍとされる。図１の各図は、図２のＡ−Ａ線に対応した拡大概略縦断面図である。   Next, the flooring manufacturing method shown in FIGS. 1 and 2 will be described in detail. In addition, each figure of FIG. 1 shows the manufacturing method with the schematic longitudinal cross-sectional view of the flooring, and each figure of FIG. 2 shows the manufacturing method with the schematic plan view of the flooring. The planar dimension of the flooring finish is 303 mm × 1818 mm. 1 is an enlarged schematic longitudinal sectional view corresponding to line AA in FIG.

この製造方法により製造される床材は、雄実部５が固定具止め用実部１とされる。つまり、雄実部５が別部材２０で形成されている（図１（ｄ）参照）。以下、手順に沿って説明する。   In the floor material manufactured by this manufacturing method, the male real part 5 is used as the fixing part real part 1. That is, the male part 5 is formed of the separate member 20 (see FIG. 1D). Hereinafter, it demonstrates along a procedure.

まず、基材１０が加工される。加工される部位は、基材１０の短辺と長辺のそれぞれ１辺の上面の角部１１である（図１（ａ）および図２（ａ）参照）。この部位が下面側に所定の厚みを残して切削されて切り欠き凹所１２が形成される。図１（ａ）および図２（ａ）では、切削部位（切り欠き凹所１２）が２点鎖線で示してある。   First, the base material 10 is processed. The part to be processed is the corner 11 on the upper surface of one side of each of the short side and the long side of the base material 10 (see FIGS. 1A and 2A). This part is cut on the lower surface side with a predetermined thickness to form a notch recess 12. In FIG. 1 (a) and FIG. 2 (a), the cutting site (notched recess 12) is indicated by a two-dot chain line.

この切り欠き凹所１２に、その凹所空間の全体を埋めるように上記別部材２０が装着貼り付けされる（図１（ａ）（ｂ）および図２（ａ）（ｂ）参照）。別部材２０の厚さ寸法は切り欠き凹所１２の深さ寸法と略同一とされる。つまり、上面側で基材１０と別部材２０とが略面一となるような厚さの別部材２０が用いられればよい。また別部材２０としては、別部材２０を切り欠き凹所１２に装着したときに基材１０の側端面よりも突出するような幅寸法のものが必要とされる。この突出寸法が形成される雄実部５の突出寸法とされる。   The separate member 20 is attached and attached to the notch recess 12 so as to fill the entire recess space (see FIGS. 1A and 1B and FIGS. 2A and 2B). The thickness dimension of the separate member 20 is substantially the same as the depth dimension of the notch recess 12. That is, the separate member 20 having such a thickness that the base member 10 and the separate member 20 are substantially flush with each other on the upper surface side may be used. Further, the separate member 20 is required to have a width dimension that protrudes from the side end surface of the base material 10 when the separate member 20 is mounted in the cutout recess 12. This projecting dimension is the projecting dimension of the male part 5 to be formed.

別部材２０は、切り欠き凹所１２に酢酸ビニル樹脂、水性ビニルウレタン樹脂などよりなる木工用接着剤をビード状に塗布した後に取り付けられる。圧着、加温により固着されるようにしてもよい。   The separate member 20 is attached to the cutout recess 12 after a woodworking adhesive made of vinyl acetate resin, aqueous vinyl urethane resin or the like is applied in a bead shape. It may be fixed by pressure bonding or heating.

ついで、表層部の硬度向上や平滑性確保のために、基材１０の上面に表面材２５が接着剤で貼り付けられる（図１（ｃ）および図２（ｂ）（ｃ）参照）。この表面材２５としては、ＭＤＦやＨＤＦなどの１ｍｍ〜３ｍｍ程度の薄厚ボードが用いられる。もちろん、その他種々の材料よりなる表面材２５を用いてもよい。なお、表面材２５の平面寸法は基材１０の平面寸法と略同一とされる。   Next, in order to improve the hardness and smoothness of the surface layer portion, the surface material 25 is attached to the upper surface of the base material 10 with an adhesive (see FIGS. 1C and 2B and 2C). As the surface material 25, a thin board of about 1 mm to 3 mm such as MDF or HDF is used. Of course, you may use the surface material 25 which consists of other various materials. The planar dimension of the surface material 25 is substantially the same as the planar dimension of the substrate 10.

つぎに、雄実部５および雌実部６が加工形成される（図１（ｄ）および図２（ｃ）参照）。加工順はいずれが先であってもよい。   Next, the male real part 5 and the female real part 6 are processed and formed (see FIG. 1 (d) and FIG. 2 (c)). Any of the processing orders may be first.

雄実部５の加工は、テノーナーあるいはモルダーにより別部材２０の一部を切除することでなされる（図１（ｄ）参照）。効率的な加工を実施するために、切除される部位は別部材２０の上面側のみとし、下面側は切除されないようにすることが望ましい。こうして、固定具止め用実部５とされる雄実部１が形成される。   The male part 5 is processed by cutting a part of the separate member 20 with a tenoner or a molder (see FIG. 1D). In order to perform efficient processing, it is desirable that the part to be excised is only the upper surface side of the separate member 20 and the lower surface side is not excised. In this way, the male part 1 which is the fixing part fixing part 5 is formed.

雌実部６の加工は、雄実部５とは反対側となる辺において基材１０の一部を切除することでなされる（図１（ｄ）参照）。こうして、非固定具止め用実部２とされる雌実部６が形成される。   The processing of the female real part 6 is performed by cutting off a part of the base material 10 on the side opposite to the male real part 5 (see FIG. 1D). In this way, the female real part 6 is formed as the non-fixing-fixing real part 2.

また、雄実部５および雌実部６の形成とともに、上面側の面取り加工がなされればよい（図１（ｄ）参照）。   Moreover, the chamfering process of the upper surface side should just be made with formation of the male real part 5 and the female real part 6 (refer FIG.1 (d)).

このようにして、基材１０の１組の対辺（図１では長辺を図示）について、固定具止め用実部１（雄実部５）および非固定具止め用実部２（雌実部６）が形成される。他の１組の対辺についても、図１（ａ）〜（ｄ）の同様の手順で固定具止め用実部１（雄実部５）および非固定具止め用実部２（雌実部６）が形成される。   In this way, with respect to a pair of opposite sides of the base material 10 (the long side is shown in FIG. 1), the fixing part fixing real part 1 (male part 5) and the non-fixing part fixing part 2 (female part) 6) is formed. Also for the other set of opposite sides, the fastener fixing real part 1 (male solid part 5) and the non-fixing fixture fastening real part 2 (female real part 6) in the same procedure as in FIGS. ) Is formed.

こうして形成された床材には表面仕上げがなされればよい。表面仕上げとしては、サンディング等による平滑化、突板や化粧シートなどの仕上げ材（不図示）の貼着がなされる。さらに塗装が施されるようにしてもよい。   The floor material thus formed may be surface-finished. As the surface finish, smoothing by sanding or the like, and sticking of a finishing material (not shown) such as a veneer or a decorative sheet is performed. Further, painting may be performed.

以上のような製造方法により、長辺と短辺のそれぞれ１辺について別部材２０よりなる雄実部５を有した床材が製造される。本床材においては、雄実部５は、床材を床下地に固定する際の、木ねじやステープルなどの固定具を打つ固定具止め用の実部とされる。この雄実部５が均質な材料よりなる別部材２０で形成されているため、従来問題とされていた、節や空隙による固定具止めの障害を回避でき、その結果、床材を床下地にしっかりと強固に固着することができる。   By the manufacturing method as described above, a flooring material having the male part 5 made of the separate member 20 for each of the long side and the short side is manufactured. In the present flooring material, the male real part 5 is a real part for fixing a fastener for hitting a fixing tool such as a wood screw or a staple when the flooring is fixed to the floor base. Since the male part 5 is formed of the separate member 20 made of a homogeneous material, it is possible to avoid the trouble of fixing the fastener due to a node or a gap, which has been a problem in the past, and as a result, the flooring is used as a floor base. It can be firmly and firmly fixed.

また、本製造方法は、別部材２０を非固定具止め用実部２とされる実部（本例では雌実部６）には取りつけないような手順となっているため、別部材２０を節約することができ、別部材２０の装着貼り付けの工数も少なくすることができる。ようするに、この製造方法によれば、固定具止めするための適切な実部を効率的に形成することができる。   Moreover, since this manufacturing method is a procedure which cannot attach the separate member 20 to the real part (the female real part 6 in this example) used as the non-fixing fixture real part 2, the separate member 20 is attached. It is possible to save, and the number of steps for attaching and attaching the separate member 20 can be reduced. Thus, according to this manufacturing method, an appropriate real part for fixing the fixture can be efficiently formed.

雄実部５を固定具止め用実部１とした床材の製造方法としては、図３に示したものであってもよい。図３に示した床材の製造方法の手順は、図１、図２に示した実施形態とおおむね同じであるが、使用する材料の形状、寸法が異なっている。なお、図３の実施形態に係る床材の製造方法については、詳細な手順の図示および説明を省略する。   As a manufacturing method of the flooring material in which the male real part 5 is the real part 1 for fixing the fastener, the one shown in FIG. 3 may be used. The procedure of the floor material manufacturing method shown in FIG. 3 is substantially the same as that of the embodiment shown in FIGS. 1 and 2, but the shape and dimensions of the materials used are different. In addition, about the manufacturing method of the flooring which concerns on embodiment of FIG. 3, illustration and description of a detailed procedure are abbreviate | omitted.

この製造方法では、図３（ａ）（ｂ）に示すように、基材１０の切り欠き凹所１２の横方向の深さを図１のものと同一とした場合、基材１０の側端面からの別部材２０の突出寸法が図１のものよりもさらに大きくなるような幅寸法の大きな別部材２０が用いられる。また、表面材２５としては、別部材２０側では基材１０の側端面よりも突出するように貼り付けられる。   In this manufacturing method, as shown in FIGS. 3A and 3B, when the lateral depth of the notch recess 12 of the base material 10 is the same as that of FIG. A separate member 20 having a large width dimension is used so that the projecting dimension of the separate member 20 from is larger than that of FIG. Moreover, as the surface material 25, it affixes so that it may protrude rather than the side end surface of the base material 10 in the separate member 20 side.

また、雄実部５は、表面材２５の側端位置に合わせるように別部材２０を切除することで形成される（図３（ｂ）参照）。雌実部６は図１のものと同様、基材１０を切除することで形成される。   Further, the male part 5 is formed by cutting away the separate member 20 so as to match the side end position of the surface material 25 (see FIG. 3B). The female real part 6 is formed by excising the base material 10 as in FIG.

このような別部材２０を用いることで、図３（ｂ）に示すように、床材の雄実部５側の側端面が基材１０の側端面よりも寸法差Ｌ分、外方に位置することとなる。つまり、図３に示した床材の製造方法によれば、基材１０の寸法よりも図３（ｂ）における寸法差Ｌ分、大きな床材を形成することができる。   By using such another member 20, as shown in FIG. 3B, the side end surface on the male part 5 side of the flooring is positioned outward by a dimensional difference L from the side end surface of the base material 10. Will be. That is, according to the floor material manufacturing method shown in FIG. 3, a floor material larger than the dimension of the base material 10 by the dimension difference L in FIG.

従来では、たとえば３０３ｍｍ×１８１８ｍｍの床材を製造する場合、切削代を考慮して、９４５ｍｍ×１８４０ｍｍの原板を３分割して製造していた。しかし、本製造方法で製造すれば、大きめの別部材２０を用いることで全体寸法を大きくすることができるので、９１０ｍｍ×１８２０ｍｍの基材１０を用いても上記床材を製造することができる。つまり、本製造方法によれば、別部材２０により寸法を稼ぐことができ、基材１０の省材料化が可能となる。なお、図１に示した床材の製造方法であっても、雄実部５は別部材２０で形成されているため、使用する原材料は製造する床材の寸法にくらべて小さいものであってよい。   Conventionally, for example, when manufacturing a floor material of 303 mm × 1818 mm, a 945 mm × 1840 mm original plate is divided into three parts in consideration of cutting allowance. However, if it manufactures with this manufacturing method, since the whole dimension can be enlarged by using the big separate member 20, the said flooring can be manufactured even if it uses the base material 10 of 910 mm x 1820 mm. That is, according to this manufacturing method, a dimension can be earned by the separate member 20, and material saving of the base material 10 is attained. Even in the flooring manufacturing method shown in FIG. 1, since the male part 5 is formed of the separate member 20, the raw material used is smaller than the size of the flooring to be manufactured. Good.

以上に説明した床材の製造方法について効果を検証するために、つぎに示す２つの実施例と、従来方法である比較例と比較検査した。   In order to verify the effects of the floor material manufacturing method described above, the following two examples were compared with a comparative example which is a conventional method.

（実施例１：図１、図２の実施形態に対応したもの）

（比較例：材料、手順について不図示）
針葉樹合板９ｍｍ厚、９４５ｍｍ×１８４０ｍｍサイズの原板の表層に、２．７ｍｍ厚、９４５ｍｍ×１８４０ｍｍサイズのＭＤＦを木工用接着剤で接着し、つぎに、ギャングソーにより３分割して３１３ｍｍ×１８４０ｍｍサイズにした。分割した材料に、０．２ｍｍ厚のナラ単板よりなる表面仕上げ材を接着し、テノーナーにより、２辺の雄実部、２辺の雌実部を加工形成した。最後に、生地研磨、生地着色、ＵＶ塗装仕上げを行った。
上記手順により、３０３ｍｍ×１８１８ｍｍサイズの床材を作製した。 (Comparative example: not shown for materials and procedures)
Adhering MDF of 2.7 mm thickness and 945 mm x 1840 mm size with glue for woodworking to the surface layer of 9 mm thick, 945 mm x 1840 mm size original board, and then dividing into 3 parts by gang saw to 313 mm x 1840 mm size did. To the divided material, a surface finishing material made of a single plate having a thickness of 0.2 mm was bonded, and a male solid part on two sides and a female real part on two sides were processed and formed by a tenoner. Finally, fabric polishing, fabric coloring, and UV coating finish were performed.
By the above procedure, a flooring material having a size of 303 mm × 1818 mm was produced.

以上の３例を比較したところ、実施例１、２では、固定具止め用実部１である雄実部５には、別部材２０が使用されているため節は表れなかった。そのため、雄実部５へのビス止め後にビスが浮くことはなかった。一方、比較例では、雄実部に針葉樹合板の節が表れた。節にビス打ちしたところ、割れが生じた。また、節のない箇所にビス打ちしたが、ビスの浮きが生じた。   As a result of comparing the above three examples, in Examples 1 and 2, since the separate member 20 was used in the male real part 5 which is the fixing-fixing real part 1, no node appeared. Therefore, the screw did not float after screwing to the male part 5. On the other hand, in the comparative example, a conifer plywood node appeared in the male part. When a screw was struck on a knot, a crack occurred. In addition, the screw was struck in a place without a knot, but the screw floated.

つぎに、図４を参照して、雌実部６を固定具止め用実部１とした床材の製造方法について説明する。なお、本実施形態に係る床材の製造方法に関する平面図については、添付を省略する。   Next, with reference to FIG. 4, a method for manufacturing a flooring material in which the female real part 6 is used as the fixing part real part 1 will be described. In addition, attachment is abbreviate | omitted about the top view regarding the manufacturing method of the flooring which concerns on this embodiment.

まず、基材１０が加工される。加工される部位は、基材１０の短辺と長辺のそれぞれ１辺の下面の角部１１である（図４（ａ）参照）。この部位が上面側に所定の厚みを残して切削されて切り欠き凹所１２が形成される。図４（ａ）には、切削部位（切り欠き凹所１２）が２点鎖線で示してある。   First, the base material 10 is processed. The part to be processed is a corner 11 on the lower surface of one side of each of the short side and the long side of the substrate 10 (see FIG. 4A). This portion is cut leaving a predetermined thickness on the upper surface side to form a notch recess 12. In FIG. 4A, the cutting site (notch recess 12) is indicated by a two-dot chain line.

この切り欠き凹所１２に、その凹所空間の全体を埋めるように別部材２０が装着貼り付けされる（図４（ａ）（ｂ）参照）。別部材２０の厚さ寸法は切り欠き凹所１２の深さ寸法と略同一とされる。つまり、下面側で基材１０と別部材２０とが略面一となるような厚さの別部材２０が用いられればよい。また別部材２０の幅寸法は、別部材２０を切り欠き凹所に装着したときに基材１０の側端面よりも突出しない、側端面が略面一となる寸法とされる。したがって、この別部材２０は図１で使用される別部材２０にくらべて幅寸法が小さくてよい。   Another member 20 is attached and attached to the notch recess 12 so as to fill the entire recess space (see FIGS. 4A and 4B). The thickness dimension of the separate member 20 is substantially the same as the depth dimension of the notch recess 12. That is, the separate member 20 having a thickness such that the base member 10 and the separate member 20 are substantially flush with each other on the lower surface side may be used. Further, the width dimension of the separate member 20 is such that when the separate member 20 is mounted in the cutout recess, the side end face does not protrude from the side end face of the base material 10 and is substantially flush. Therefore, this separate member 20 may be smaller in width than the separate member 20 used in FIG.

別部材２０は、切り欠き凹所１２に酢酸ビニル樹脂、水性ビニルウレタン樹脂などよりなる木工用接着剤をビード状に塗布した後に取り付けられる。圧着、加温により固着されるようにしてもよい。   The separate member 20 is attached to the cutout recess 12 after a woodworking adhesive made of vinyl acetate resin, aqueous vinyl urethane resin or the like is applied in a bead shape. It may be fixed by pressure bonding or heating.

ついで、表層部の硬度向上や平滑性確保のために、基材１０の上面に表面材２５が接着剤で貼り付けられる（図４（ｂ）（ｃ）参照）。この表面材２５としては、ＭＤＦやＨＤＦなどの１ｍｍ〜３ｍｍ程度の薄厚ボードが用いられる。もちろん、その他種々の材料よりなる表面材２５を用いてもよい。なお、表面材２５の平面寸法は、雄実部５の加工を考慮すれば雄実部２５側には貼り付けが不要であるため、基材１０の平面寸法よりも小さくてよい。   Next, in order to improve the hardness and smoothness of the surface layer portion, the surface material 25 is attached to the upper surface of the base material 10 with an adhesive (see FIGS. 4B and 4C). As the surface material 25, a thin board of about 1 mm to 3 mm such as MDF or HDF is used. Of course, you may use the surface material 25 which consists of other various materials. Note that the planar dimension of the surface material 25 may be smaller than the planar dimension of the base material 10 because it is not necessary to attach the male material 25 to the male solid part 25 side in consideration of the processing of the male solid part 5.

つぎに、雄実部５および雌実部６が加工形成される（図４（ｃ）参照）。加工順はいずれが先であってもよい。   Next, the male real part 5 and the female real part 6 are formed by machining (see FIG. 4C). Any of the processing orders may be first.

雌実部６の加工は、テノーナーあるいはモルダーにより別部材２０の一部が切除されることでなされる（図４（ｄ）参照）。こうして、固定具止め用実部１とされる雌実部６が形成される。   The processing of the female real part 6 is performed by cutting off a part of the separate member 20 with a tenor or a molder (see FIG. 4D). In this way, the female real part 6 which is the fixing-fixing real part 1 is formed.

雄実部６の加工は、雌実部５とは反対側となる辺における基材１０の一部を切除することでなされる（図４（ｄ）参照）。こうして、非固定具止め用実部２とされる雄実部６が形成される。   The male part 6 is processed by cutting off a part of the base material 10 on the side opposite to the female part 5 (see FIG. 4D). In this way, the male real part 6 which is the non-fixing tool fixing real part 2 is formed.

また、雄実部５および雌実部６の形成とともに、上面側の面取り加工がなされればよい（図４（ｄ）参照）。   Further, it is only necessary to chamfer the upper surface side with the formation of the male real part 5 and the female real part 6 (see FIG. 4D).

このようにして、基材１０の１組の対辺（図例では長辺）について、固定具止め用実部１（雌実部６）および非固定具止め用実部２（雄実部５）が形成される。他の１組の対辺についても、図４（ａ）〜（ｄ）の同様の手順で固定具止め用実部１（雌実部６）および非固定具止め用実部２（雄実部５）が形成される。   In this way, with respect to one pair of opposite sides (long side in the illustrated example) of the base material 10, the fastener fixing real part 1 (female real part 6) and the non-fixing fixture fastening real part 2 (male real part 5). Is formed. With respect to the other set of opposite sides, the fixing-fixing actual part 1 (female real part 6) and the non-fixing-fixing fixing real part 2 (male real part 5) are performed in the same procedure as in FIGS. ) Is formed.

こうして形成された床材には表面仕上げがなされればよい。表面仕上げとしては、サンディング等による平滑化、突板や化粧シートなどの仕上げ材の貼着がなされる。さらに塗装が施されるようにしてもよい。   The floor material thus formed may be surface-finished. As the surface finish, smoothing by sanding or the like, and sticking of a finishing material such as a veneer or a decorative sheet is performed. Further, painting may be performed.

以上のような製造方法により、長辺と短辺のそれぞれ１辺について別部材２０よりなる雌実部６を有した床材が製造される。本床材においては、雌実部６は、床材を床下地に固定する際の、木ねじやステープルなどの固定具を打つ固定具止め用実部とされる。この雌実部６が均質な材料よりなる別部材２０で形成されているため、床材を床下地にしっかりと強固に固着することができる。   By the manufacturing method as described above, a flooring having a female real part 6 made of another member 20 for each of the long side and the short side is manufactured. In the present flooring, the female real part 6 is a fixing part stopping real part for hitting a fixing tool such as a wood screw or a staple when the flooring is fixed to the floor base. Since the female real part 6 is formed of the separate member 20 made of a homogeneous material, the floor material can be firmly and firmly fixed to the floor base.

また、この製造方法では、固定具止め用実部１である雌実部６のみに別部材２０を用いればよいため、使用する別部材２０を節約することができ、別部材２０の装着貼り付けの工数も少なくすることができる。   Moreover, in this manufacturing method, since the separate member 20 should just be used only for the female real part 6 which is the fixing | fixed-fixing real part 1, the separate member 20 to be used can be saved, and attachment attachment of the separate member 20 is carried out. The number of man-hours can be reduced.

なお、雌実部６を固定具止め用実部１とした床材を製造する方法では、図１のものと同一寸法の床材を製造する場合でも、大きな寸法の基材１０が必要とされる。しかしながらその反面、図１のものにくらべて、使用する別部材２０は幅寸法が小さなものでよく、別部材２０については省材料化ができる。   In addition, in the method of manufacturing a flooring material in which the female real part 6 is used as the fixing-fixing real part 1, a large-sized base material 10 is required even when a flooring of the same size as that of FIG. 1 is manufactured. The On the other hand, however, the separate member 20 to be used may have a smaller width dimension than the one shown in FIG.
