【考案の属する技術分野】[Technical field to which the device belongs]

この考案は、床板に関し、更に詳しくは、確実な施工が可能な床板及びそれを使った建築耕造物に関する。 The present invention relates to a floorboard, and more specifically, a floorboard capable of reliable construction and Concerning the used construction tillage.

【０００２】[0002]

【従来の技術】[Prior art]

従来から、床板を使った床の敷設施工が行われているが、その際、床材の組み付けを容易にするために、前もって端面に加工が施してある床板が使用されている。この床板の敷設施工方法としては種々の方法が開発されている。例えば、図８に示す方法は床板を床下材に固定する手順を示す図であり、このように、釘を使って床板を下地材（床下板）に敷設していく。 Conventionally, floor laying construction using floor boards has been performed, but at that time, floor material assembly Pre-machined floorboards are used to facilitate attachment. It Various methods have been developed as a construction method for laying the floor board. For example, the method shown in FIG. 8 is a diagram showing a procedure for fixing the floor board to the underfloor material. The floor board is laid on the base material (bottom floor board) using nails.

【０００３】なお、ここでの接合部は長手方向の端面を示している。この方法では、まず、下地材の上に第１床板Ａを載置する。そして、床板の端面（雄部）に釘を打ち付けて固定する。次に、第１床板Ａの端面（雄部）に他の床板（第２の床板Ｂ）の一方の端面（雌部）を嵌合することで接合する。その後、第２の床板Ｂの他方の端面（雄部）に釘を打ち付けて固定する。次に、第２床板Ａの端面（雄部）に第３の床板Ｃの端面（雌部）を嵌合することで接合する。このような接合手順を順次繰り返していくことにより、広範囲に床板が下地材（床下板）３００に対して敷設施工されていくのである。[0003] In addition, the joint part here has shown the end surface of a longitudinal direction. In this method, first, the first floor board A is placed on the base material. Then, nails are fixed to the end face (male part) of the floor plate to fix it. Next, one end surface of the other floor board (second floor board B) (to the end surface (male part) of the first floor board A ( It is joined by fitting the female part). Then, a nail is struck and fixed to the other end surface (male part) of the second floor board B. Next, the end surface (male part) of the second floor board A is fitted to the end surface (female part) of the third floor board C. Join with. By repeating such a joining procedure in sequence, the floorboard is widely used as the base material. The underfloor plate 300 is laid and constructed.

【０００４】このような床板の端面の接合例として、従来から、図９に示すような床板の端面が多く使用されている。この接合構造は、床板１００の端面（ここでは床板の小口や側面をいう）に雄部である凸部１１３が形成され、他方の床板２００の端面には雌部である凹部２１３が形成されている構造である。このような接合は、小口ではほぞとほぞ穴による接合、また側面では印籠じゃにり、又はさね造りによる接合といわれているものである。今、このような床板を下地材（床下板）の上に接合して敷設していくには、第１の床板１００の雄部である凸部１１３にそれと接合すべき第２の床板２００の雌部である凹部２１３を嵌合により接合する。[0004] As an example of joining the end faces of such a floor plate, conventionally, as shown in FIG. The surface is often used. This joint structure has a male member on the end surface of the floorboard 100 (herein, the edge or side surface of the floorboard). A convex portion 113, which is a portion, is formed, and a concave portion 2 that is a female portion is formed on the end surface of the other floor board 200. 13 is formed. This kind of joining is done by tenon and mortise at the small edge, and at the side by the inro It is said to be joined by glue or tongue-making. Now, in order to join and lay such a floor board on the base material (underfloor board), Of the second floorboard 200 to be joined to the convex portion 113 which is the male part of the first floorboard 100. The concave portion 213, which is a female portion, is joined by fitting.

【０００５】凸部１１３の長さと凹部２１３の深さが一致する場合は、図１０（Ａ）に示すように正確に各部分が接合する。ところが、床板は前もって設定寸法に製造されているが、一般に、その加工により寸法上の誤差が生ずるのは避けられない。誤差が生じて凸部１１３の長さと凹部２１３の深さが一致しなくなった場合を想定する。[0005] When the length of the convex portion 113 and the depth of the concave portion 213 are the same, it is shown in FIG. So each part joins exactly. However, the floorboard is manufactured to the set dimensions in advance, but in general, It is inevitable that more dimensional errors will occur. If an error occurs and the length of the convex portion 113 and the depth of the concave portion 213 do not match, Suppose.

【０００６】例えば、雄部の凸部１１３が雌部の凹部２１３より長い場合、雄部である凸部１１３の先（すなわち頂部１１３Ａ）が雌部である凹部２１３の底２１３Ａに早く当接するような寸法関係にあると、図１０（Ｂ）に示すように、雄部の両肩１１１、１１２と雌部の先（足先）２１１、２１２とが当接（接触）しなくなるために、上面と下面とにて、第１の床板１００と第２の床板２００との間に間隙Ｔが生ずる。[0006] For example, when the convex portion 113 of the male portion is longer than the concave portion 213 of the female portion, the convex portion which is the male portion The tip of 113 (that is, the top 113A) quickly moves to the bottom 213A of the recess 213 that is the female part. When the size relationship is such that the male parts come into contact with each other, as shown in FIG. 11, 112 and the tips of the female parts (toes) 211, 212 no longer contact (contact) Therefore, a gap T is formed between the first floor plate 100 and the second floor plate 200 on the upper surface and the lower surface. Occurs.

【０００７】また、雄部の凸部１１３の先１１３Ａが雌部の凹部２１３の底２１３Ａに早く当接しなくても、図１０（Ｃ）に示すように、雄部の下側の肩部１１２が雌部の下側の先２１２に早く当接するような寸法関係にあると、雄部の上側の肩部１１１と雌部の上側の先２１１との間に、同様に間隙Ｔが生ずる。また、図１０（Ｄ）に示すように、雄部の上側の肩部１１２が雌部の上側の先２１２に早く当接するような寸法関係にあると、雄部の下側の肩部１１１と雌部の下側の先２１１との間に、同様に間隙Ｔが生ずる。[0007] In addition, the tip 113A of the convex portion 113 of the male portion quickly moves to the bottom 213A of the concave portion 213 of the female portion. Even if they do not come into contact with each other, as shown in FIG. If the dimensional relationship is such that the lower tip 212 abuts earlier, the upper shoulder portion 11 of the male portion Similarly, a gap T is formed between 1 and the upper tip 211 of the female portion. Further, as shown in FIG. 10 (D), the shoulder 112 on the upper side of the male portion is located at the tip of the upper side of the female portion. If the dimensional relationship is such that it quickly contacts the 212, the lower shoulder 111 of the male part and the female part 111 Similarly, a gap T is formed between the lower tip 211 and the lower tip 211.

【０００８】このような接合関係により床板間に生じた間隙Ｔは〔図１０（Ｂ）、図１０（Ｃ）の場合〕、上方から見た場合に、垂直に深く切れ込んでいる如くに視認される。このようなことから、誤差が生じた場合には、２／３の確率で上面にて床板間の間隙が生ずることになる。接合部を上方から見た場合、第１の床板１００と第２の床板２００との間に間隙Ｔが生じないようにするには、第１の床板１００の雄部である凸部１１３の先１１３Ａが第２の床板２００の雌部である凹部２１３の底２１３Ａに他の部分よりも早く当接しないようにすること、すなわち図１０（Ｂ）に示す如くならないこと、及び第１の床板１００の雄部の下側の肩部１１２が第２の床板２００の雌部の下側の先２１２に他の部分より早く当接しないようにすること、すなわち、図１０（Ｃ）に示す如くならないことが必要である。[0008] The gap T generated between the floor plates due to such a bonding relationship is [Fig. 10 (B), Fig. 10 ( In the case of C)], when viewed from above, it is visually recognized as a deep vertical cut. It Therefore, if an error occurs, there is a 2/3 probability that the floor plate will be Gap will be created. When the joint is viewed from above, there is a space between the first floor board 100 and the second floor board 200. In order to prevent the gap T from occurring, the tip of the convex portion 113 that is the male portion of the first floor board 100 113A is different from the bottom 213A of the concave portion 213, which is the female portion of the second floor plate 200, from other portions. Make sure that they do not come into contact with each other sooner, that is, as shown in FIG. And the shoulder 112 on the lower side of the male part of the first floor plate 100 is the female part of the second floor plate 200. To prevent the lower tip 212 of the part from coming into contact earlier than the other parts, ie It is necessary that it does not become as shown in FIG.

【０００９】このようなことから床板を敷設施工する場合、第１の床板に対して第２の床板を接合して間隙が生ずるようであれば、第２の床板を裏返して使う必要がある。表裏である両側を自由に使う〔選んで好む側を表（上方）にする〕ことはできない。床板が無垢材である場合は、その地肌面が好まれるために上下（すなわち表裏）の両側とも使えることができる方が極めて有用であり、且つ施工性の自由度が増す点からも作業が効率的である。しかるに、上記のような接合構造ではこの要求に答えられない。[0009] Therefore, when laying and constructing a floorboard, the first floorboard and the second floorboard are If a gap is created by joining the two, it is necessary to turn the second floorboard over and use it. It is not possible to freely use both sides, which are the front and back sides [the side you prefer and choose is the front (upper)] Absent. If the floorboard is made of solid wood, the ground surface is preferred, so that ) It is extremely useful to be able to use both sides of the Work is also efficient in terms of increasing the number. However, the above-mentioned joining structure cannot meet this demand.

【００１０】一方、床板を床下材３００に取り付けるためには、固定用の釘４を使うが、このような従来の場合、図１１に示すように、第１の床板の雄部の脇（凸部１１３と肩部１１１の境界部分）から、金槌等を使って釘４を打ち込む（Ａ→Ｂ）。ところが、その際、金槌等による衝撃のため雄部である凸部１１３が変形したり極端には折れたりする場合がある。凸部１１３が変形すると、他の床板の雌部である凹部２１３に嵌まり込まなくなり、折れた場合、接合はまず不可能である。[0010] On the other hand, in order to attach the floor board to the underfloor material 300, the fixing nail 4 is used. In the conventional case such as, as shown in FIG. 11, the side of the male part of the first floorboard (the convex part 113 Then, the nail 4 is driven in using a hammer or the like from the boundary portion between the shoulder portion 111 and the shoulder portion 111 (A → B). However, at that time, the convex portion 113, which is the male portion, is deformed due to the impact of a hammer or the like. It may break extremely. When the convex portion 113 is deformed, the convex portion 113 does not fit into the concave portion 213 which is the female portion of the other floor board. If it breaks and breaks, joining is almost impossible.

【００１１】また、打ち込む際に、凸部１１３の脇に釘頭４１が入るので、凸部１１３が邪魔になって、釘頭４１を叩きにくいこともある。更に、釘頭４１は、第２の床板の凹部を嵌め込む際に邪魔にする。そのため、ポンチを使って釘頭４１を床板に叩き込む必要がある。また、床板の凸部１１３は、運搬中や施工中に他部材にぶつけると、傷が付き易い。更に、凹部２１３の一方の足部の壁厚が床板全厚に比べて小さいために、この壁厚の部分が長期間の間に反り返ったりする。それが床板を敷設施工した状態で床表面の浮き現象となって現れる〔図８（Ｃ）の拡大部、参照）〕。更には、雌部の足部は、床板の全厚みの一部であるために壁厚が薄くならざるを得ず、熱に弱く燃え易い。このようなことから、床板にほぞ溝を形成し、凹凸部を嵌合して接合する構造を採用した場合には施工上や機能上の限界があったのである。[0011] In addition, since the nail head 41 enters the side of the convex portion 113 when driving, the convex portion 113 does not interfere. It may become a devil and it may be difficult to hit the nail head 41. Further, the nail head 41 is an obstacle when fitting the concave portion of the second floor plate. Therefore, it is necessary to drive the nail head 41 into the floor plate using a punch. In addition, the convex portion 113 of the floor plate may be damaged if it hits against other members during transportation or construction. easy. Further, since the wall thickness of one foot of the recess 213 is smaller than the total thickness of the floorboard, The wall thickness part warps over a long period of time. It appears as a floating phenomenon on the floor surface when the floorboard is laid [Fig. 8 (C ) Enlarged section, see)). In addition, the female foot is a part of the total thickness of the floorboard, so the wall thickness must be thin. It doesn't get enough, it is vulnerable to heat and easily burns. Because of this, a structure in which a mortise groove is formed on the floor board and the uneven parts are fitted and joined There was a limit in construction and function when adopting.

【考案の実施の形態】[Embodiment of device]

以下、本考案を具体的な実施の形態を挙げ図面に基づいて説明する。図１は、本考案の床板の実施の形態を示す外観図であり、また図２は、その床板の両方の端部を拡大して示す断面図である（なお便宜的に長尺な床板の中央部を一部省略して示している）。このような床板を使って、下地材（床下板）に床を敷設施工していく手順を図３に示す。図３は、床板を床下材に固定する手順を示す図である（釘頭を収納可能な凹部は、細部であるために省略して示した）。 Hereinafter, the present invention will be described with reference to the drawings with reference to specific embodiments. 1 is an external view showing an embodiment of a floorboard of the present invention, and FIG. 2 is a floorboard thereof. FIG. 3 is an enlarged cross-sectional view showing both ends of the board (note that the central portion of the long floor board is shown for convenience sake). Are partially omitted). Figure showing the procedure for laying a floor on a base material (bottom floor plate) using such a floor plate 3 shows. FIG. 3 is a diagram showing a procedure for fixing the floor plate to the underfloor material (a concave portion capable of storing a nail head). Is omitted because it is a detail).

【００２８】まず図３（Ａ）で先述したように、第１の床板Ａを床下板３の上に置き、釘４で固定する。そして第１床板Ａの端面と次の第２の床板Ｂの端面とを接合し第２の床板Ｂを釘で固定する。次に、今度は第２の床板Ｂの他方の端面に第３の床板Ｃの端面を接合する。以下同様な手順で接合を順次繰り返していくことにより、下地材（床下板）の上に広い範囲に渡って床板が敷設されていく。[0028] First, as described above with reference to FIG. 3A, the first floor board A is placed on the underfloor board 3 and the nails 4 Fix with. Then, the end surface of the first floor board A and the end surface of the next second floor board B are joined together to form the second floor board B. Secure with nails. Next, this time, the end surface of the third floor board C is joined to the other end surface of the second floor board B. By repeating the bonding in the same procedure below, the base material (bottom floor plate) Floor boards are laid over a wide area on the top.

【００２９】本考案の床板は、後述するように、突き合わせる端面が山形状の雄部と雌部との接合のため両床板の突き合わせが行い易い。また、例えば、床下板３にカーブがあった場合も、同様な手順で敷設される利点がある。因みに、前述した従来のさね造りの接合構造では、雄部の凸部と雌部の凹部との嵌合が不可能となる。[0029] As will be described later, the floorboard of the present invention has a male part and a female part whose end faces to be butted are mountain-shaped. It is easy to butt the two floor boards because of the joints. In addition, for example, even if the underfloor plate 3 has a curve, it can be laid by the same procedure. There is a point. By the way, in the above-mentioned conventional tongue-shaped joint structure, the convex portion of the male portion and the concave portion of the female portion are Cannot be fitted.

【００３０】さて本考案の床板は、図２の拡大図に示すように、一方の端面である第１端面を山形状の雄部１として、他方の端面である第２端面を山形状の雌部２として形成する。山形状の雄部１には図でいう上側に位置する第１雄傾斜面１１と下側に位置する第２雄傾斜面１２とが形成されており、両斜面の衝合により頂部１３が形成されている。この雄部の頂部１３は、角が無くて曲面となっていることがより好ましい〔図２（Ｂ）参照〕。[0030] Now, as shown in the enlarged view of FIG. 2, the floorboard of the present invention has a first end surface which is one end surface. As a mountain-shaped male portion 1 and the second end surface, which is the other end surface, as a mountain-shaped female portion 2. To achieve. The mountain-shaped male portion 1 is located on the lower side with the first male inclined surface 11 located on the upper side in the figure. The second male inclined surface 12 is formed, and the top 13 is formed by the abutment of both inclined surfaces. Has been. It is more preferable that the apex 13 of this male part has a curved surface without corners. 2 (B)].

【００３１】同様に、床板の山形状の雌部２には、上側に位置する第１雌傾斜面２１と下側に位置する第２雌傾斜面２２とがあり、両斜面が中央で衝合されて底部２３が形成されている。これらの頂部１３や底部２３は、板厚の中央部に形成されている。そして、雄部１における第１雄傾斜面１１と第２雄傾斜面１２とのなす角（α ）は、雌部２における第１雌傾斜面２１と第２雌傾斜面２２とのなす角（β）と等しい。[0031] Similarly, the mountain-shaped female portion 2 of the floor plate includes the first female inclined surface 21 located on the upper side and the lower female side. And a second female inclined surface 22 located at the bottom, and both inclined surfaces are abutted at the center to form a bottom portion 23. Is made. The top portion 13 and the bottom portion 23 are formed in the central portion of the plate thickness. The angle formed by the first male inclined surface 11 and the second male inclined surface 12 in the male portion 1 (α ) Is an angle (β) formed by the first female inclined surface 21 and the second female inclined surface 22 in the female portion 2. equal.

【００３２】しかし、後述するように、雄部１における第１雄傾斜面１１と第２雄傾斜面１２とのなす角（α）は、雌部２における第１雌傾斜面２１と第２雌傾斜面２２とのなす角（β）より大きくすることがより好ましい。ここで、αは１２０°〜１６０°が好ましく、特に１５０°がより好ましい。一方、この雄部１の第１雄傾斜面１１には、後述するように、施工時、釘頭を隠すために釘頭４１が収納可能な凹部１１Ａが設けられている。[0032] However, as described later, the first male inclined surface 11 and the second male inclined surface in the male part 1 The angle (α) formed with 12 is the first female inclined surface 21 and the second female inclined surface 22 in the female portion 2. It is more preferable to make it larger than the angle (β) formed by and. Here, α is preferably 120 ° to 160 °, and particularly preferably 150 °. On the other hand, as described later, the first male inclined surface 11 of the male part 1 has a nail head during construction. A recess 11A is provided for accommodating the nail head 41 for concealment.

【００３３】この凹部１１Ａは端面に沿って連続的に設けられていることが好ましく、断面形状は略三角形が好ましい。凹部１１Ａの底には、釘頭４１を支持するための受け面１１Ａ１が形成されており、この受け面の角度θは第１雄傾斜面１１の角度α／２より小さい傾斜（例えば４５°）を有する。[0033] This recess 11A is preferably provided continuously along the end face, The shape is preferably a substantially triangular shape. A receiving surface 11A1 for supporting the nail head 41 is formed on the bottom of the recess 11A. The angle θ of this receiving surface is smaller than the angle α / 2 of the first male inclined surface 11 (example 45 °).

【００３４】同様に、第２雄傾斜面１２にも受け面１２Ａ１を有する凹部１２Ａが設けられており、受け面の角度も第２雄傾斜面１２の角度α／２より、小さい傾斜を有する。なお、このような受け面の角度θは、上方からの釘の打ち込み易さの観点から、１５°〜４０°が好ましく、特に好ましくは３０°である。因みに、従来の接合構造（図１１参照）においては、凸部１１３の形状のために４５°を越えるようになり、釘が打ち込みにくい。このように端面が形成された床板を、先述したように、順次、継いで接合していくのである。[0034] Similarly, the second male inclined surface 12 is also provided with a recess 12A having a receiving surface 12A1. And the angle of the receiving surface is also smaller than the angle α / 2 of the second male inclined surface 12 It Note that such an angle θ of the receiving surface is set from the viewpoint of the ease of driving the nail from above. , 15 ° to 40 ° are preferable, and 30 ° is particularly preferable. By the way, in the conventional joining structure (see FIG. 11), due to the shape of the protrusion 113, The angle is more than 45 ° and it is difficult to drive nails. The floorboards with the end faces thus formed are successively spliced and joined as described above. I will go.

【００３５】ここで第１の床板とそれに隣接する第２の床板との接合関係について述べる。図４は両床板を接合する前の状態を示し、また図５は両床板を接合した後の状態（断面）を示す。なお、ここで第１の両床板の接合構造は、本考案でよりベストな接合構造であるところの、雄部１の第１雄傾斜面１１と第２雄傾斜面１２との間の角度αを、雌部２の第１雌傾斜面２１と第２雌傾斜面２２との間の角度βより大きく設定したものを示した。いま、第１の床板Ａの山形状の雄部１に、第２の床板Ｂの山形状の雌部２を接合したとする。[0035] Here, the joining relationship between the first floorboard and the second floorboard adjacent thereto will be described. Fig. 4 shows the state before joining the floor boards, and Fig. 5 shows the state after joining the floor boards. The state (cross section) is shown. In addition, the first joint structure of both floor plates is the best joint structure in the present invention. Where the angle α between the first male inclined surface 11 and the second male inclined surface 12 of the male part 1 is It is set to be larger than the angle β between the first female inclined surface 21 and the second female inclined surface 22 of the female portion 2. I showed you Now, the mountain-shaped male portion 1 of the first floor plate A is connected to the mountain-shaped female portion 2 of the second floor plate B. Let's say

【００３６】図６は、接合状態の各態様を示す。図６の（Ａ）に示すように、雄部１の第１雄傾斜面１１と第２雄傾斜面１２との間の角度αが、雌部２の第１雌傾斜面２１と第２雌傾斜面２２との間の角度β と等しい場合は、上下面に隙間は生じなくてピッタリ接合する（なお、各所番号は図２及び図４を参照のこと）。[0036] FIG. 6 shows each aspect of the bonded state. As shown in FIG. 6A, the first male inclined surface 11 and the second male inclined surface 12 of the male part 1 are Is between the first female inclined surface 21 and the second female inclined surface 22 of the female portion 2. If it is equal to See FIG. 2 and FIG. 4).

【００３７】ところが先述したように、床板を製造する場合に加工する際、設計寸法に比べて面の傾斜に誤差が生じる場合がある。例えば、雄部１の第１雄傾斜面１１と雌部２の第１雌傾斜面２１、雄部１の第２雄傾斜面１２と雌部２の第２雌傾斜面２２、等の各々角度に設計寸法と実際寸法の間に誤差が生ずる場合がある。[0037] However, as mentioned earlier, when processing when manufacturing floorboards, compared to design dimensions An error may occur in the inclination of the surface. For example, the first male inclined surface 11 of the male part 1, the first female inclined surface 21 of the female part 2, the first male inclined surface 21 of the male part 1, 2 The design dimensions and the actual dimensions are set at the respective angles of the male inclined surface 12 and the second female inclined surface 22 of the female portion 2. There may be an error in the law.

【００３８】図６の（Ｂ）に示すように、雄部の第１雄傾斜面１１と第２雄傾斜面１２との間の角度αが、雌部の第１雌傾斜面２１と第２雌傾斜面２２との間の角度βより小さい場合は、上下両面に隙間Ｔが生ずる。また雄部１の第１雄傾斜面１１と第２雄傾斜面１２との間の角度αが、雌部２の第１雌傾斜面２１と第２雌傾斜面２２との間の角度βより大きい場合では次の２通りがある。[0038] As shown in FIG. 6B, the first male inclined surface 11 and the second male inclined surface 12 of the male part are The angle α is between the angle β between the first female inclined surface 21 and the second female inclined surface 22 of the female portion. When it is small, a gap T is formed on both upper and lower surfaces. Further, the angle α between the first male inclined surface 11 and the second male inclined surface 12 of the male part 1 is If the angle β between the first female inclined surface 21 and the second female inclined surface 22 is larger than There are two ways.

【００３９】一つは、（Ｃ）に示すように、両床板Ａ、Ｂが下面で接触して、上面に両床板に間隙Ｔが生ずる場合である。この場合、第１の床板Ａの雄部１の頂部１３と第２の床板Ｂの雌部２の底部２３との間には間隙が形成される。[0039] First, as shown in (C), both floor boards A and B are in contact with each other on the lower surface, and both floor boards are on the upper surface. This is the case where a gap T is generated in. In this case, the top part 13 of the male part 1 of the first floorboard A and the bottom part 2 of the female part 2 of the second floorboard B A gap is formed between the two.

【００４０】他の一つは、（Ｄ）に示すように、両床板Ａ、Ｂが上面で接触して下面に両床板に間隙Ｔが生ずる場合である。この場合も、第１の床板Ａの雄部１の頂部１３と第２の床板Ｂの雌部２の底部２３との間には間隙が形成される。本考案において、このような両床板間に生じた間隙Ｔは、雄部の雄傾斜面が直下に見えしかも斜めに傾斜しているために間隙自体が垂直方向に深く視認されない。そのために、間隙が生じたとしても目立ちにくいのである。因みに、先述した従来例（図１０、図１１参照）においては、間隙の奥深くまで見えて極めて目立ち易い。[0040] As for the other one, as shown in (D), both floor boards A and B are in contact with each other on the upper surface and both floor plates are on the lower surface. This is the case where a gap T is created in the plate. Also in this case, the top part 13 of the male part 1 of the first floor plate A and the bottom part of the female part 2 of the second floor plate B A gap is formed between this and 23. In the present invention, the gap T formed between the two floor plates is such that the male inclined surface of the male part is straight. The gap itself cannot be seen deep in the vertical direction because it is visible below and is inclined at an angle. Yes. Therefore, even if a gap is created, it is not noticeable. By the way, in the above-mentioned conventional example (see FIGS. 10 and 11), the gap is deep inside. It is very visible and visible.

【００４１】本考案の床板を使った接合構造においては、雄部１の第１雄傾斜面１１と第２雄傾斜面１２との間の角度αを、雌部２の第１雌傾斜面２１と第２雌傾斜面２２との間の角度βより大きく寸法設定することがより好ましい。このように設定することにより、上記（Ｂ）の如く上下両面に隙間Ｔが生ずるようなケースは、加工誤差を考慮しても、製造後は殆どなくなる。[0041] In the joining structure using the floorboard of the present invention, the first male inclined surface 11 and the second male inclined surface 11 of the male part 1 are The angle α between the male inclined surface 12 and the male inclined surface 12 is defined as the first female inclined surface 21 and the second female inclined surface 22 of the female portion 2. It is more preferable to set the dimension larger than the angle β between and. By setting in this way, a gap T is generated on both upper and lower surfaces as in (B) above. Such a case is almost eliminated after manufacturing, even if the processing error is taken into consideration.

【００４２】そして上記（Ｃ）及び（Ｄ）となるケースが殆どとなり、しかも（Ｄ）の如く下面に両床板の間隙Ｔが生ずるケースは、確率的にその半分である。そのため、（Ｃ）の如く上面に両床板の間隙Ｔが生ずるケースは確率的に１／２である。因みに、従来、両床板の上面に間隙Ｔが生ずる確率は２／３である。[0042] Most of the cases (C) and (D) above occur, and as shown in (D) The number of cases in which a gap T between both floor plates occurs on the lower surface is half that probability. Therefore, the case where the gap T between the two floor plates occurs on the upper surface as in (C) is stochastically 1 / It is 2. Incidentally, conventionally, the probability that the gap T is generated on the upper surfaces of both floor plates is 2/3.

【００４３】このようなことから、床板のどの面を上に敷設しても間隙が上面に露出するように現れるケースは従来より少なくなる。また、例え、上面に間隙が露出するケースの場合でも、従来のように隙間が目立つようなことはなく、そのため床板の表裏とも使えて自由度が増し、床板の敷設施工の作業効率が大となる。[0043] Because of this, no matter which side of the floorboard is laid on top, the gap is exposed at the top. There are fewer cases that appear as before. In addition, even in the case where the gap is exposed on the upper surface, the gap will not be visible as in the past. Since it does not stand up, it can be used on the front and back of the floorboard, increasing the degree of freedom and Greater work efficiency in installation work.

【００４４】更にまた、両床板の間に形成される空間（間隙）に簡単にしかも確実に接着剤（例えば無機接着剤）を充填することができ、間隙をより目立たなくでき、同時に接合強度を向上することができる。雌部の雌傾斜面に接着剤を付着させ雄部に対して押し付けることで全体的に均一に接着剤が行き渡る。そして、釘頭を収納する凹部１１Ａが接着剤で埋まり釘浮きが無くなる。[0044] Furthermore, the space (gap) formed between the two floor boards can be easily and securely bonded with an adhesive. (Eg inorganic adhesive) can be filled to make the gaps less noticeable and at the same time Further, the bonding strength can be improved. Adhesive is attached to the female inclined surface of the female part and pressed against the male part to make the entire surface even. The adhesive spreads all over. Then, the concave portion 11A for accommodating the nail head is filled with the adhesive to prevent the nail from floating.

【００４５】因みに従来のさね造りの接合構造ではこれらのメリットは期待できない。本考案の床板においては、床板の加工上の寸法誤差が出て、第１の床板の雄部と第２の床板の雌部との間で製造上の角度ずれが生じても、それによって上面に間隙が生ずるケースも少なく、また間隙が上面に生じても目立たなく、更に接着剤による接合強度を上げ易い。[0045] By the way, these advantages cannot be expected in the conventional tongue-and-groove joint structure. In the floorboard of the present invention, there is a dimensional error in processing the floorboard, and the male part of the first floorboard Even if there is a manufacturing angle deviation between the female part of the second floorboard and the There are few gaps, and even if a gap is formed on the upper surface, it is not conspicuous and more adhesive It is easy to increase the bonding strength with the agent.

【００４６】さて、本考案の床板においては、釘頭を隠すことができる他の特徴もある。一般に、下地材（床下板）３に床板を取り付ける場合は（敷設する場合）、固定用の固着具、例えば釘４１等が使用される。先述したように、本考案においては、雄部１の第１雄傾斜面１１及び第２第１雄傾斜面１２には釘頭４１を隠して突出しない状態におくための凹部１１Ａ及び凹部１２Ａが形成されている。[0046] Now, the floorboard of the present invention has another feature that can hide the nail head. Generally, when attaching a floor plate to the base material (bottom floor plate) 3 (when laying), A fixed fastener such as a nail 41 is used. As described above, in the present invention, the first male inclined surface 11 and the second first inclined surface 11 of the male part 1 are used. A concave portion 11A for hiding the nail head 41 on the male inclined surface 12 so as not to project, and A recess 12A is formed.

【００４７】床板に対して、釘を打ち込むには、床板を下地材（床下板）の上に置き、その雄部１の第１雄傾斜面１１に対して釘を打ち込む。その際、釘は、その第１雄傾斜面１１に形成された凹部１１Ａの受け面１１Ａ１に対して略垂直となるように打ち込む（当然、床板に対しては斜め方向から打ち込むこととなる）。受け面１１Ａ１がある角度、例えば４５度の傾斜となっている場合、釘４を床下板に対して約４５度の傾斜角で打ち込むことが好ましい。[0047] To drive a nail into the floorboard, place the floorboard on the base material (bottom floorboard) and A nail is driven into the first male inclined surface 11 of the male part 1. At that time, the nail is provided with the receiving surface 11A of the recess 11A formed in the first male inclined surface 11 thereof. Drive so that it is almost perpendicular to 1 (Of course, the floor board is driven diagonally. Will be inserted). If the receiving surface 11A1 is inclined at an angle, for example, 45 degrees, fix the nail 4 on the floor. It is preferable to drive at an inclination angle of about 45 degrees with respect to the lower plate.

【００４８】釘４は、打ち込んだ後、最終的に釘頭４１がこの凹部１１Ａに収納されて隠れるために、第１の床板Ａの雄部１に第２の床板Ｂの雌部２を押し付けながら接合した場合、釘頭４１が雌部２の第１傾斜部２１を妨害するようなことがない（図７参照）。すなわち、床板Ａと床板Ｂの両床板を接合した場合に、釘頭４１が邪魔をしないために両床板に間隙が生ずるようなことはなくなる。釘頭を隠すための凹部１１Ａは、第１雄傾斜面１１と第２雄傾斜面１２の両方に形成することが好ましい。[0048] The nail 4 is hidden after the nail head 41 is finally stored in the recess 11A after being driven. In order to join the male part 1 of the first floor board A while pressing the female part 2 of the second floor board B In this case, the nail head 41 does not interfere with the first inclined portion 21 of the female portion 2 (Fig. 7). That is, when the floor boards A and B are joined together, the nail heads 41 do not interfere. As a result, there will be no gap between the floor boards. The recess 11A for hiding the nail head is provided on both the first male inclined surface 11 and the second male inclined surface 12. It is preferable to form it.

【００４９】ところで、本考案の床板は端面においても十分厚みがあり、先述した従来のように（図９〜図１１参照）、雌部の側壁により板厚の薄い部分が生ずる点を回避できる。そのため、長年、使っている間に側壁が反り返ったりすることはない。更にまた、従来は薄い部分を有するために熱による加熱が速く起き易いが、本考案では床板内を熱がより伝達し易く熱に比較的強いものとなる。[0049] By the way, the floorboard of the present invention has a sufficient thickness even at the end face, and is (See Figs. 9-11), avoiding the point where the side wall of the female part causes a thin plate part it can. Therefore, the side wall does not warp during use for many years. Furthermore, since it has a thin portion in the past, heating by heat is likely to occur quickly, In the invention, the heat is more easily transferred through the floorboard and the heat is relatively strong.

【００５０】以上説明した床板は、不燃処理を施すことで不燃性を有する床板となる。不燃性を付与するには、不燃処理液、例えば、硼素化合物を含む弱酸又は弱アルカリの金属塩水溶液に燐酸及びシランカップリング剤加えて混合水溶液とし、該混合水溶液にポリフェノール系化合物を主成分とする植物抽出物を加えた処理液を使って、床板（又は床板加工する前の段階の木材）に対して減圧含浸させる処理方法が採用される。[0050] The floorboard described above becomes a floorboard having incombustibility by performing incombustibility treatment. To impart nonflammability, a nonflammable treatment liquid, for example, a weak acid or weak acid containing a boron compound is used. Add phosphoric acid and a silane coupling agent to the aqueous solution of Lucari's metal salt to form a mixed aqueous solution, Treatment in which a plant extract containing a polyphenol compound as a main component is added to the mixed aqueous solution Use the liquid to impregnate the floorboard (or wood before the floorboard processing) under reduced pressure. A processing method is adopted.

【００５１】以下、本考案における床板の施工例を挙げて説明する。[0051] Hereinafter, the construction example of the floor board in the present invention will be described.

【実施例】【Example】

不燃処理液を使って不燃処理を施した厚さ２０ｍｍ（縦）×１００ｍｍ（横） ×２０００ｍｍ（長さ）の床板（杉板）を床下板の上に敷設した。ここで、不燃処理液は、硼素化合物を含む弱酸又は弱アルカリの金属塩水溶液に燐酸及びシランカップリング剤加えて混合水溶液とし、該混合水溶液にポリフェノール系化合物を主成分とする植物抽出物を加えた処理液を使った。 20mm (vertical) x 100mm (horizontal) with non-combustible treatment using non-combustible treatment liquid A floor plate (cedar plate) of × 2000 mm (length) was laid on the lower floor plate. Here, the non-combustible treatment liquid is a weak acid or weak alkali metal salt aqueous solution containing a boron compound. Phosphoric acid and a silane coupling agent are added to form a mixed aqueous solution. A treatment liquid containing a plant extract containing an enol compound as a main component was used.

【００５２】床板を接合する場合、床板の表や裏が自由に使えて施工する場合に自由度があり極めて便利である。また、釘を打ち込んで床下材に床板を固定する場合、釘を打ち込んだ後も、釘頭が凹部に隠れるために接合の邪魔にならず間隙が全く生じない。また、一方の床板の雌部に接着剤を付与して別の床板の雄部に押し付けるだけで簡単に接着剤が両床板の間隙に充填された。また緩いカーブを有する床下板に敷設したが確実に接合ができた。[0052] When joining floorboards, the front and back of the floorboards can be used freely and there is a degree of freedom when constructing. It is extremely convenient. In addition, when fixing the floor board to the underfloor by hammering in the nail, even after driving the nail, Since the head is hidden in the recess, it does not interfere with the joining and no gap is created. Also, just apply adhesive to the female part of one floor board and press it against the male part of another floor board Then, the adhesive was easily filled in the gap between both floor boards. Moreover, it was laid on the underfloor plate having a gentle curve, but it was possible to reliably join.

【比較例１】厚さ２０ｍｍ（縦）×１００ｍｍ（横）×２０００ｍｍ（長さ）の床板（杉板）を床下板の上に敷設した。床板は、図８に示すような、ほぞとほぞ穴を有するものを使った。敷設に際しては、ほぞとほぞ穴との嵌合が製造誤差によりスムースに行われにくい。床板を接合した部分には、隙間が生じており、その間隙を上方から見ると釘頭が僅かに視認できた。床板は、常に一方側（表側）しか使用できないために施工する場合に、表裏を確認する必要があり面倒であった。[Comparative Example 1] 20 mm (length) x 100 mm (width) x 2000 mm (length) floor board (cedar board) ) Was laid on the under floor plate. The floor plate used had a tenon and a tenon as shown in FIG. When laying, the mortise and tenon hole are fitted smoothly due to manufacturing errors. Peg. There is a gap in the part where the floor boards are joined, and if you look at the gap from above, the nail head Was slightly visible. The floorboard can only be used on one side (front side) at all times, so when installing It was troublesome to check.

【００５４】また、一方の床板の雌部に接着剤を付与して別の床板の端部の雄部に押し付けて接合したが、両床板の間隙に接着剤が、充分、充填されなかった。また、一方の床板の雌部を、接着剤を付与した別の床板の雌部に押し付けて接合したが、同様に両床板の間隙に充分接着剤が充填されなかった。この場合、雄部の下側の肩部には接着剤を付与するのは極めて困難であった。また緩いカーブを有する床下板に敷設したが、ほぞとほぞ穴との嵌合がしにくく接合が難しい。[0054] Also, apply adhesive to the female part of one floor board and press it against the male part of the end of another floor board. However, the adhesive was not sufficiently filled in the gap between the floor boards. Also, press the female part of one floor plate against the female part of another floor plate to which an adhesive has been applied. However, similarly, the adhesive was not sufficiently filled in the gap between both floor boards. In this case, it was extremely difficult to apply the adhesive to the lower shoulder of the male part. Although it was laid on the underfloor plate that has a gentle curve, it is difficult to fit the tenon with the tenon. Difficult to join.

【００５５】以上、本考案を説明したが、本考案は実施の形態や実施例に限定されるものではなく、その目的に沿う限り種々の変形例が可能である。床板における雌面や雄面の傾斜面の角度は適宜選択可能である。第１端面に設けた釘が収納可能な凹部の形状は、受け面を有する限りその形は自由でありその受け面の傾斜角も適宜選択できる。また、床板に打ち込む釘としては、ネジ、ボルト、ピン等を含むものである。また床板を適用する対象物としては、床の他、壁材、柱材、天井材、屋根材として、更には種々の建築構造物に取り込んで使用することができる。例えば、本考案の床板を使った壁材を有する建屋は、その部分において同様なメリットを有することとなる。[0055] The present invention has been described above, but the present invention is not limited to the embodiments and examples. However, various modifications are possible as long as the purpose is met. The angles of the female and male inclined surfaces of the floor plate can be selected as appropriate. As long as it has a receiving surface, the shape of the recess that can accommodate the nail provided on the first end surface is It is free and the inclination angle of the receiving surface can be appropriately selected. Further, the nails to be driven into the floor plate include screws, bolts, pins and the like. In addition to floors, flooring materials include wall materials, pillar materials, ceiling materials, and roofing materials. Further, it can be incorporated into various building structures for use.

【考案の効果】[Effect of device]

本考案の床板は、床板の一方の第１端面を山形状の雄部とし、他方の第２端面を山形状の雌部とし、前記第１端面の雄部に釘頭を収納可能な凹部を形成した床板であることから、両側が区別なく使え、また釘頭が隠れて施工効率がよい。また、床厚の薄い部分がないために、従来のホゾ接合のように薄い部分の反り返りが生ずるようなことはない。更に雄面と雌面との間に間隙が生じても、その間隙の底が浅いために目立ち難い。また、床下材が緩いカーブを描いていても接合が簡単に行える。 The floorboard of the present invention has one first end surface of the floorboard as a mountain-shaped male portion and the other second end surface of the floorboard. Is a mountain-shaped female part, and a concave part for accommodating a nail head is formed in the male part of the first end face. Since it is a plate, both sides can be used without distinction, and the nail heads are hidden, resulting in good construction efficiency. Also, because there is no thin floor part, the warpage of thin parts as in conventional hozo joints There is no return. Furthermore, even if there is a gap between the male and female surfaces, it is difficult to stand out because the gap is shallow at the bottom. Yes. Also, even if the underfloor material has a gentle curve, joining can be easily performed.
