Description

本発明は、床材に関するものである。 The present invention relates to flooring.

床材には、側端部に雄実と雌実が形成されたものがあり、複数の床材を配置するとき、隣り合う床材の雄実と雌実を組み合わせることで、複数の床材が一体化されて1枚ずつの床材の浮き上がりが防止されたり、床材の位置決めが行われたりする。 Some bedding materials have male and female seeds formed on the side edges. When arranging multiple bedding materials, combining the male and female seeds of adjacent bedding materials allows multiple bedding materials to be combined. are integrated to prevent individual flooring materials from lifting up and to position the flooring materials.

特許文献1には、竹・木複合床板において、傾き端部に設けられたダブル係合構造を採用して、床板同士間を接続することが開示されている。 Patent Document 1 discloses that, in bamboo/wood composite floorboards, a double engagement structure provided at the inclined end portions is employed to connect the floorboards to each other.

床下地材又は既存の床材などの表面上に、複数の床材を新規に敷設する場合において、隣接する床材同士の間(継ぎ目)は、可能な限り小さく隙間(目隙)がないことが望ましい。しかし、床材が床下地材等に固定されていない状態では、新規に敷設する床材の位置決めが困難であり、施工中に目隙が生じやすいという難点がある。特に、床材に対して釘(例えばピンネイルなど)を打ち込むと破損しやすい薄板材の場合、釘で固定できないため上述した目隙が生じやすい。 When installing multiple new flooring materials on the surface of subflooring materials or existing flooring materials, the spaces (joints) between adjacent flooring materials should be as small as possible and there should be no gaps (gaps). is desirable. However, if the flooring material is not fixed to the subfloor material or the like, it is difficult to position the newly installed flooring material, and gaps are likely to occur during construction. In particular, in the case of thin sheet materials that are easily damaged when nails (for example, pin nails, etc.) are driven into the flooring material, the above-mentioned gaps are likely to occur because the flooring cannot be fixed with nails.

また、MDF(中密度繊維板)等の木質基材を主体とする床材は、木質材の性質上、床材が設置された後、木質基材が乾燥して収縮することがある。また、木質材以外の合成樹脂、ゴム又は金属などの材料を基材とする床材についても、冬期などの低温環境下において収縮するおそれがある。基材が収縮した結果、隣り合う床材同士の継ぎ目に目隙が生じたり、目隙が大きくなったりする。 Further, due to the nature of the wood material, the wood base material may dry and shrink after the floor material is installed, such as a floor material mainly made of a wood base material such as MDF (medium density fiberboard). Furthermore, flooring materials based on materials other than wood, such as synthetic resin, rubber, or metal, may also shrink in low-temperature environments such as in winter. As a result of the shrinkage of the base material, gaps may occur or become larger at the seams between adjacent flooring materials.

本発明は、このような事情に鑑みてなされたものであって、隣り合う床材同士の間に形成される隙間を低減することができ、容易に敷設作業を行うことが可能な床材を提供することを目的とする。 The present invention has been made in view of these circumstances, and provides a flooring material that can reduce gaps formed between adjacent flooring materials and that can be easily installed. The purpose is to provide.

上記課題を解決するために、本発明の床材は以下の手段を採用する。
すなわち、本発明に係る床材は、基材を有する床材であって、前記基材の側端部に設けられ、前記基材の一方の板面に連続して形成され前記板面に対して傾斜した第1傾斜面を有する凹部と、前記基材の側端部に設けられ、前記凹部の前記第1傾斜面よりも前記基材の長さ方向先端側又は幅方向先端側に形成され前記板面に対して傾斜した第2傾斜面を有する凸部と、前記第1傾斜面と前記第2傾斜面の間に形成され、前記凹部における前記凸部側の端部よりも突出した突出部とを備え、前記凹部は、別の床材の側端部に形成された前記凸部に対して接触して、互いに嵌合可能である。
In order to solve the above problems, the flooring material of the present invention employs the following means.
That is, the flooring material according to the present invention is a flooring material having a base material, which is provided at a side end of the base material, is continuously formed on one plate surface of the base material, and is provided on a side edge of the base material, and is formed continuously on one plate surface of the base material. a recessed portion having a first inclined surface that is inclined at a distance; a convex portion having a second slope inclined with respect to the plate surface; and a protrusion formed between the first slope and the second slope and protruding beyond an end of the concave portion on the side of the convex portion. The recessed portion is capable of coming into contact with the convex portion formed on the side end portion of another flooring material and being able to fit into each other.

この構成によれば、基材の側端部に設けられた第1傾斜面を有する凹部と、基材の側端部に設けられた第2傾斜面を有する凸部と、第1傾斜面と第2傾斜面の間に形成された突出部を備え、凹部は、別の床材の側端部に形成された凸部に対して接触して、互いに嵌合可能である。凸部の第2傾斜面は、凹部の第1傾斜面よりも基材の長さ方向先端側又は幅方向先端側に形成され、突出部は、凹部における凸部側の端部よりも突出している。凹部、凸部及び突出部は、実を構成し、隣り合う床材同士は、実を介して組み合わせ可能である。突出部同士が係合することによって、隣り合う床材同士がずれにくくなる。
また、凹部の第1傾斜面が、基材の一方の板面に連続して形成されることから、鉛直下方に向かって移動させながら、既に設置されている床材に対して新たに設置する床材を配置可能である。
According to this configuration, the recessed portion having the first inclined surface provided at the side end of the base material, the convex portion having the second inclined surface provided at the side end of the base material, and the first inclined surface. It includes a protrusion formed between the second inclined surfaces, and the recess is capable of coming into contact with a protrusion formed on a side end of another flooring material and fitting into each other. The second inclined surface of the convex portion is formed closer to the lengthwise tip side or the widthwise tip side of the base material than the first inclined surface of the concave portion, and the protruding portion is formed to protrude further than the end portion of the concave portion on the protrusion side. There is. The concave portion, the convex portion, and the protruding portion constitute a fruit, and adjacent flooring materials can be combined via the fruit. By engaging the protrusions with each other, adjacent flooring materials are less likely to shift.
In addition, since the first inclined surface of the recess is formed continuously on one board surface of the base material, it is possible to install a new one on the already installed flooring material while moving it vertically downward. Flooring can be placed.

上記発明において、前記凹部の前記第1傾斜面、又は、前記凸部の前記第2傾斜面は、前記基材の他方の板面に対して20度以上70度以下でもよい。 In the above invention, the first inclined surface of the concave portion or the second inclined surface of the convex portion may be 20 degrees or more and 70 degrees or less with respect to the other plate surface of the base material.

傾斜角度が20度未満である場合、凸部の先端部が鋭角になり過ぎるため破損しやすくなる。他方、傾斜角度が70度を超える場合、傾斜が緩やかな場合と比べて、施工時において突出部同士を確実に係合できず、床材同士を正しく接合できないおそれがある。 If the inclination angle is less than 20 degrees, the tip of the convex portion will be too acute and will be easily damaged. On the other hand, when the inclination angle exceeds 70 degrees, compared to a case where the inclination is gentle, the protrusions cannot be reliably engaged with each other during construction, and the flooring materials may not be properly joined together.

上記発明において、前記突出部の突出高さは、0.5mm以上2.5mm以下でもよい。 In the above invention, the protrusion height of the protrusion may be 0.5 mm or more and 2.5 mm or less.

突出高さが0.5mm未満である場合、突出部の強度が不十分となるため破損しやすくなり、また、突出部同士の係合が外れやすくなる。他方、突出高さが2.5mmを超える場合、突出部の先端が運搬や施工の際に作業者や他の物品に引っ掛かりやすくなり破損するおそれがある。 If the protrusion height is less than 0.5 mm, the strength of the protrusions will be insufficient, making them easy to break, and the protrusions will also tend to disengage from each other. On the other hand, if the protrusion height exceeds 2.5 mm, the tip of the protrusion may easily get caught by workers or other objects during transportation or construction, and there is a risk of damage.

上記発明において、前記突出部において前記凹部側に形成される係合面の傾斜角度は、前記基材の他方の板面に対して15度以上90度以下でもよい。 In the above invention, the inclination angle of the engagement surface formed on the concave side of the protrusion may be 15 degrees or more and 90 degrees or less with respect to the other plate surface of the base material.

傾斜角度が15度未満である場合、突出部同士の係合が外れやすくなる。他方、傾斜角度が90度を超える場合、突出部を形成する際の切削加工が困難になり、先端が鋭角となるため破損しやすくなる。 When the inclination angle is less than 15 degrees, the protrusions tend to disengage from each other. On the other hand, if the inclination angle exceeds 90 degrees, cutting when forming the protrusion becomes difficult, and the tip becomes an acute angle, making it easy to break.

上記発明において、前記凹部の前記第1傾斜面と前記凸部の前記第2傾斜面は、平行であり、断面が点対称となるように形成されてもよい。 In the above invention, the first inclined surface of the concave portion and the second inclined surface of the convex portion may be parallel to each other, and may be formed so that their cross sections are point symmetrical.

この構成によれば、凹部と凸部は、互いに全面にわたって接触して嵌合可能であり、突出部が基材の厚さ方向の中間近傍に形成されることから、先端部が破損しにくくなる。 According to this configuration, the concave portion and the convex portion can be fitted together by contacting each other over the entire surface, and since the protruding portion is formed near the middle in the thickness direction of the base material, the tip portion is less likely to be damaged. .

本発明によれば、凹部は、別の床材の側端部に形成された凸部に対して接触して、互いに嵌合可能であるため、隣り合う床材同士の間に形成される隙間を低減することができ、また、突出部同士が係合することによって、隣り合う床材同士がずれにくくなるため、容易に敷設作業を行うことができる。 According to the present invention, the concave portions can come into contact with the convex portions formed on the side edges of another flooring material and fit into each other, so that a gap is formed between adjacent flooring materials. Furthermore, since the protrusions engage with each other, adjacent flooring materials are less likely to shift, making it easier to install the flooring.

以下に、本発明の一実施形態に係る床材1について、図面を参照して説明する。
床材1は、一方向に長い長尺状部材であり、複数の床材1が側端部同士を対向させながら平行に配置されることによって、建築物の室内における床を形成する。床材1は、下地材上に敷設される新設の床や、既存の床上に敷設されるリフォームの床のいずれの場合にも適用可能である。
Below, a flooring material 1 according to an embodiment of the present invention will be described with reference to the drawings.
The flooring material 1 is an elongated member that is elongated in one direction, and a plurality of flooring materials 1 are arranged in parallel with their side ends facing each other to form a floor in the room of a building. The floor material 1 can be applied to either a newly constructed floor laid on a base material or a renovated floor laid on an existing floor.

床材1は、図1に示すように、基材2と、吸着材3などを有し、基材2と吸着材3が積層されている。図1は、本実施形態に係る床材1を示す縦断面図であって、床材1の長さ方向又は幅方向に対して平行に切断した図であり、床材1の長さ方向又は幅方向の中間部分を省略して示している。 As shown in FIG. 1, the floor material 1 includes a base material 2, an adsorbent 3, etc., and the base material 2 and the adsorbent 3 are laminated. FIG. 1 is a longitudinal cross-sectional view showing a flooring material 1 according to the present embodiment, and is a diagram cut parallel to the length direction or width direction of the flooring material 1. The middle part in the width direction is omitted from the illustration.

基材2の表面側には、化粧シートが更に積層されてもよい。化粧シートは、例えばオレフィンシートなどの合成樹脂シート、化粧紙、突板などである。 A decorative sheet may be further laminated on the surface side of the base material 2. Examples of the decorative sheet include a synthetic resin sheet such as an olefin sheet, decorative paper, and veneer.

基材2と吸着材3の間にはクッション材が積層されてもよい。クッション材は、例えば合成樹脂発泡体である。合成樹脂発泡体は、例えばエチレン酢酸ビニル共重合体、ポリエチレン、ポリウレタン、ポリオレフィンなどである。クッション材が設けられることによって、歩行性を向上させるなどの利点が得られる場合がある。 A cushioning material may be laminated between the base material 2 and the adsorbent material 3. The cushioning material is, for example, a synthetic resin foam. Examples of the synthetic resin foam include ethylene vinyl acetate copolymer, polyethylene, polyurethane, and polyolefin. Providing the cushioning material may provide advantages such as improving walkability.

基材2は、例えばMDF(中密度繊維板)、ハードボード、インシュレーションボード、合板、無垢材、集成材、単板積層材(LVL)、パーティクルボードなどの木質材である。また、基材2は、木質材に限定されず、硬質又は軟質の合成樹脂板、天然ゴム又は合成ゴムなどのゴム板、アルミニウム合金などの金属板でもよい。基材2の側端部には、後述する実が形成される。 The base material 2 is, for example, a wood material such as MDF (medium density fiberboard), hardboard, insulation board, plywood, solid wood, laminated wood, laminated veneer lumber (LVL), or particle board. Further, the base material 2 is not limited to a wooden material, and may be a hard or soft synthetic resin board, a rubber board such as natural rubber or synthetic rubber, or a metal board such as an aluminum alloy. At the side end portions of the base material 2, a fruit, which will be described later, is formed.

吸着材3は、床材1を下地材や既存の床に対して固定させる。吸着材3は、例えばアクリル系樹脂発泡体である。アクリル系樹脂発泡体は、例えばフィルム又はシートであり、基材2又はクッション材に接着される。アクリル系樹脂発泡体は、塗布材であるアクリル樹脂が基材2又はクッション材に塗布されたものでもよい。アクリル系樹脂発泡体の表面に形成される複数の微細な気泡による凹部それぞれが吸盤となって、吸着材3が下地材や既存の床に吸着する。 The adsorbent 3 fixes the flooring 1 to the base material or existing floor. The adsorbent 3 is, for example, an acrylic resin foam. The acrylic resin foam is, for example, a film or a sheet, and is adhered to the base material 2 or the cushion material. The acrylic resin foam may be one in which an acrylic resin as a coating material is applied to the base material 2 or a cushion material. Each of the recesses formed by a plurality of fine bubbles formed on the surface of the acrylic resin foam acts as a suction cup, and the adsorbent 3 adsorbs to the base material or existing floor.

床材1の裏面側、すなわち、吸着材3の表面には、施工前の運搬時において離型紙が貼付されていることが望ましい。これにより、施工前に吸着材3の吸着性が低下することを防止できる。離型紙は、施工時に剥がされて、吸着材3を露出させてから、床材1が床下地材上などに敷設される。 It is desirable that a release paper be attached to the back side of the flooring material 1, that is, the surface of the adsorbent material 3 during transportation before construction. Thereby, it is possible to prevent the adsorption properties of the adsorbent 3 from decreasing before construction. The release paper is peeled off during construction to expose the adsorbent 3, and then the flooring material 1 is laid on the subfloor material.

なお、本実施形態では、吸着材3が設けられる場合について説明したが、必ずしも吸着材3が床材1に設けられなくてもよい。この場合、吸着材3の代わりに、接着剤、両面テープ等の粘着剤、ピンネイル等の釘によって、床材1が下地材や既存の床に対して固定される。 In addition, although this embodiment demonstrated the case where the adsorbent 3 was provided, the adsorbent 3 does not necessarily need to be provided in the floor material 1. In this case, instead of the adsorbent 3, the flooring material 1 is fixed to the base material or the existing floor using an adhesive such as an adhesive, a double-sided tape, or a nail such as a pin nail.

床材1がリフォームの床に適用されるリフォームフロアである場合、床材1は、例えば、化粧シート、基材2、クッション材、吸着材3、離型紙が表面側から順番に積層されたものである。床材1の厚さは、例えば基材2が1mm、クッション材が1mmで、総厚が約2mmである。リフォームフロアとしての床材1は、一般的な床材よりも基材2が薄いため、曲がり易く、床下地材に不陸がある場合でもなじみ易いという利点がある。また、施工時において床材1をハサミで切断でき、施工が容易である。 When the floor material 1 is a renovated floor applied to a renovated floor, the floor material 1 is, for example, one in which a decorative sheet, a base material 2, a cushion material, an absorbent material 3, and a release paper are laminated in order from the surface side. It is. The thickness of the floor material 1 is, for example, 1 mm for the base material 2 and 1 mm for the cushion material, and the total thickness is about 2 mm. Since the base material 2 of the floor material 1 used as a remodeled floor is thinner than that of a general floor material, it has the advantage of being easy to bend and easily conforming even when the subfloor material is uneven. Moreover, the flooring material 1 can be cut with scissors during construction, making construction easy.

なお、リフォームフロアとしての床材1の基材2は、例えばMDFであり、板厚は、上述した例に限定されず、例えば1mm以上5mm以下である。基材2の板厚が1mm未満である場合、曲げ強度が不十分となり、運搬や施工の際、折れや割れなどの破損が生じるおそれがある。他方、基材2の板厚が5mmを超える場合、床材1が既存の床の一部に施工されたとき、床材1の床面と、床材1が敷設されない既存の床面との段差が大きくなるため、歩行者が躓いて転倒するおそれがある。
なお、新設の床に適用される場合、床材1は、一般的な床材と同様に、例えば約12mmである。
In addition, the base material 2 of the flooring material 1 as a remodeled floor is, for example, MDF, and the board thickness is not limited to the above-mentioned example, and is, for example, 1 mm or more and 5 mm or less. If the thickness of the base material 2 is less than 1 mm, the bending strength will be insufficient, and there is a risk that damage such as bending or cracking will occur during transportation or construction. On the other hand, when the thickness of the base material 2 exceeds 5 mm, when the floor material 1 is installed on a part of an existing floor, the difference between the floor surface of the floor material 1 and the existing floor surface on which the floor material 1 is not installed. Due to the large step difference, pedestrians may trip and fall.
In addition, when applied to a newly installed floor, the floor material 1 has a thickness of, for example, about 12 mm, like a general floor material.

[実形状]
次に、本実施形態に係る床材1の基材2に形成される実について説明する。
実は、長尺状の床材1において、対向する短辺の側端部同士、又は、対向する長辺の側端部同士で対となるように形成される。図1では、一の床材1において対向する短辺又は長辺の側端部の断面を示している。実は、床材1の短辺又は長辺の側端部に沿って平行に形成される。
[Actual shape]
Next, the fruit formed on the base material 2 of the flooring material 1 according to this embodiment will be explained.
In fact, in the elongated flooring material 1, the side ends of opposing short sides or the side ends of opposing long sides are formed in pairs. FIG. 1 shows a cross section of opposite short sides or long sides of one flooring material 1. As shown in FIG. In fact, they are formed in parallel along the side edges of the short or long sides of the flooring 1.

実は、断面がほぼ直角三角形となるように、床材1の表面(床面)に対して傾斜した傾斜面を有する。隣り合う床材1の対向する実同士が組み合わされると、それぞれの実が点対称に配置されるように、対向する実に対応して実の形状が形成される。点対称の中心点は、基材2の厚さ方向の中間である。図3に示すように、隣り合う床材1の実同士が組み合わされ、床材1が接合された状態で、二つの床材1の表面は面一となる。 In fact, it has an inclined surface that is inclined with respect to the surface (floor surface) of the flooring material 1 so that the cross section is approximately a right triangle. When the opposing nuts of adjacent flooring materials 1 are combined, the shapes of the nuts are formed corresponding to the opposing nuts so that the respective nuts are arranged point-symmetrically. The center point of point symmetry is the middle of the base material 2 in the thickness direction. As shown in FIG. 3, when the adjacent flooring materials 1 are combined and the flooring materials 1 are joined, the surfaces of the two flooring materials 1 become flush.

床材1の表面側が上面となるように配置したとき、一側端側の実は、図1に示すように、例えば下向きに傾斜した傾斜面を有する凹部5a及び凸部6aを備える。凸部6aの傾斜面は、凹部5aの傾斜面よりも基材2の長さ方向先端側又は幅方向先端側に形成される。凹部5aの傾斜面と凸部6aの傾斜面は平行であり、断面が点対称となるように形成される。 When the floor material 1 is arranged so that the surface side is the upper surface, the one end side actually has a concave portion 5a and a convex portion 6a having, for example, a downwardly inclined slope, as shown in FIG. The sloped surface of the convex portion 6a is formed closer to the leading end in the length direction or the leading end in the width direction of the base material 2 than the sloped surface of the recessed portion 5a. The inclined surface of the recessed portion 5a and the inclined surface of the convex portion 6a are parallel to each other, and the cross sections are formed to be point symmetrical.

他側端側の実は、図1に示すように、例えば上向きに傾斜した傾斜面を有する凹部5b及び凸部6bを備える。凸部6bの傾斜面は、凹部5bの傾斜面よりも基材2の長さ方向先端側又は幅方向先端側に形成される。凹部5bの傾斜面と凸部6bの傾斜面は、平行であり、断面が点対称となるように形成される。 As shown in FIG. 1, the other end actually includes a concave portion 5b and a convex portion 6b having, for example, an upwardly inclined slope. The inclined surface of the convex portion 6b is formed closer to the tip end in the length direction or the tip end side in the width direction of the base material 2 than the inclined surface of the recessed portion 5b. The sloped surface of the recess 5b and the sloped surface of the convexity 6b are parallel to each other, and are formed so that their cross sections are point symmetrical.

凹部5aと凸部6b、又は、凸部6aと凹部5bは、全面にわたって接触して嵌合可能である。また、突出部4a,4bが基材2の厚さ方向の中間近傍に形成されることから、先端部が破損しにくくなる。 The concave portion 5a and the convex portion 6b, or the convex portion 6a and the concave portion 5b, can be fitted into contact with each other over the entire surface. Further, since the protrusions 4a and 4b are formed near the middle of the base material 2 in the thickness direction, the tip portions are less likely to be damaged.

凹部5aの傾斜面と凸部6aの傾斜面は、同一面ではなく、凹部5aと凸部6aが長辺に形成される場合は床材1の幅方向、短辺に形成される場合は床材1の長さ方向にずれた位置に形成される。凹部5bの傾斜面と凸部6bの傾斜面も、同様に床材1の幅方向又は長さ方向にずれた位置に形成される。凹部5aと凸部6aのずれ量と、凹部5bと凸部6bのずれ量は同一である。 The slope of the recess 5a and the slope of the convex part 6a are not the same plane, and when the recess 5a and the convex part 6a are formed on the long sides, they are in the width direction of the flooring 1, and when they are formed on the short sides, they are in the width direction of the flooring 1. It is formed at a position shifted in the length direction of the material 1. The inclined surfaces of the recessed portions 5b and the inclined surfaces of the convex portions 6b are similarly formed at positions shifted in the width direction or length direction of the flooring 1. The amount of deviation between the recess 5a and the protrusion 6a is the same as the amount of deviation between the recess 5b and the protrusion 6b.

凹部5bにおいて基材2の表面側近傍の傾斜面は、基材2の表面に連続して形成される。特許文献1に示すように、床板の表面近傍において、凹部の傾斜面の上方を覆うように先端側に張り出した張出部が形成される場合、新たに敷設する床板の凸部が、既に設置されている床板の表面側の張出部に干渉しないように、既に設置されている床板の側端部よりも外側から斜め下方へ床板を移動させる必要がある。 The inclined surface near the surface side of the base material 2 in the recessed portion 5b is formed continuously on the surface of the base material 2. As shown in Patent Document 1, when a protruding portion protruding toward the tip side so as to cover the upper side of the slope of the recess is formed near the surface of the floorboard, the protrusion of the newly installed floorboard is already installed. It is necessary to move the floorboard diagonally downward from the outside of the side edge of the floorboard that has already been installed so as not to interfere with the overhang on the surface side of the floorboard that has already been installed.

他方、本実施形態では、凹部5bの傾斜面と基材2の表面が90度よりも大きく180度未満で交わり、また、表面側において張出部が形成されずに、凹部5bの傾斜面が基材2の表面に連続して形成されているため、図2に示すように、鉛直下方に向かって、または、既に配置されている床材1の長さ方向又は幅方向の中間側から斜め下方へ移動しながら、床材1を配置できる。したがって、床材1を敷設する際、突出部4a,4bが係合しやすい方向に床材1を移動させることができるため、床材1の敷設作業が容易である。 On the other hand, in this embodiment, the inclined surface of the recess 5b and the surface of the base material 2 intersect at an angle greater than 90 degrees and less than 180 degrees, and the inclined surface of the recess 5b is Since it is formed continuously on the surface of the base material 2, as shown in FIG. The flooring material 1 can be placed while moving downward. Therefore, when laying the flooring 1, the flooring 1 can be moved in a direction in which the protrusions 4a and 4b can easily engage with each other, so that the work of laying the flooring 1 is easy.

凹部5aにおいて床材1の裏面側近傍の傾斜面は、基材2の裏面に連続して形成される。特許文献1に示すように、床板の裏面近傍において、凹部の傾斜面の下方において先端側に張り出した張出部が形成される場合、新たに敷設する床板の裏面側の張出部が、既に設置されている床板の凸部に干渉しないように、既に設置されている床板の側端部よりも外側から斜め下方へ床板を移動させる必要がある。 The inclined surface near the back side of the floor material 1 in the recess 5 a is formed continuously on the back surface of the base material 2 . As shown in Patent Document 1, when a protruding portion protruding toward the tip side below the slope of the recess is formed in the vicinity of the back surface of the floorboard, the protruding portion on the back side of the newly installed floorboard has already been formed. In order to avoid interfering with the protrusions of the installed floorboards, it is necessary to move the floorboards diagonally downward from the outside of the side edges of the already installed floorboards.

他方、本実施形態では、凹部5aの傾斜面と基材2の裏面が90度よりも大きく180度未満で交わり、また、裏面側において張出部が形成されないため、図2に示すように、鉛直下方に向かって、または、既に配置されている床材1の長さ方向又は幅方向の中間側から斜め下方へ移動しながら、床材1を配置できる。したがって、床材1を敷設する際、突出部4a,4bが係合しやすい方向に床材1を移動させることができるため、床材1の敷設作業が容易である。 On the other hand, in this embodiment, the inclined surface of the recess 5a and the back surface of the base material 2 intersect at an angle of greater than 90 degrees and less than 180 degrees, and since no overhang is formed on the back surface side, as shown in FIG. The flooring material 1 can be placed while moving vertically downward or obliquely downward from the intermediate side in the length direction or width direction of the already placed flooring material 1. Therefore, when laying the flooring 1, the flooring 1 can be moved in a direction in which the protrusions 4a and 4b can easily engage with each other, so that the work of laying the flooring 1 is easy.

突出部4aと突出部4bは、互いに係合可能な形状を有している。突出部4aと突出部4bが係合することによって、隣り合う床材1同士がずれにくくなる。 The protrusion 4a and the protrusion 4b have shapes that allow them to engage with each other. By engaging the protrusion 4a and the protrusion 4b, adjacent flooring materials 1 become difficult to shift from each other.

凹部5aの傾斜面と凸部6aの傾斜面の間には、凹部5aにおける凸部6a側の端部、すなわち、凹部5aの上端よりも下方に突出した突出部4aが形成される。突出部4aは、鉛直方向下向きに突出しており、突出部4aの断面における頂点は、凸部6aの下端と一致する。 A protrusion 4a is formed between the slope of the recess 5a and the slope of the protrusion 6a, which protrudes downward from the end of the recess 5a on the protrusion 6a side, that is, the upper end of the recess 5a. The protrusion 4a protrudes downward in the vertical direction, and the apex in the cross section of the protrusion 4a coincides with the lower end of the protrusion 6a.

凹部5bの傾斜面と凸部6bの傾斜面の間には、凹部5bにおける凸部6b側の端部、すなわち、凹部5bの下端よりも上方に突出した突出部4bが形成される。突出部4bは、鉛直方向上向きに突出しており、突出部4bの断面における頂点は、凸部6bの上端と一致する。 A protrusion 4b is formed between the slope of the recess 5b and the slope of the protrusion 6b, which protrudes upward from the end of the recess 5b on the protrusion 6b side, that is, the lower end of the recess 5b. The protrusion 4b protrudes upward in the vertical direction, and the vertex of the cross section of the protrusion 4b coincides with the upper end of the protrusion 6b.

突出部4aには、凹部5a側に係合面が形成され、突出部4bには、凹部5b側に係合面が形成される。突出部4aに形成される係合面と突出部4bに形成される係合面は平行である。図1に示す例では、突出部4a,4bに形成される係合面は、基材2の板面に対して90度である。 The protrusion 4a has an engagement surface formed on the recess 5a side, and the protrusion 4b has an engagement surface formed on the recess 5b side. The engagement surface formed on the protrusion 4a and the engagement surface formed on the protrusion 4b are parallel. In the example shown in FIG. 1 , the engagement surfaces formed on the protrusions 4 a and 4 b are at 90 degrees with respect to the plate surface of the base material 2 .

突出部4aは、凹部5aと凸部6aのずれ量に応じた突出高さを有し、突出部4bは、凹部5bと凸部6bのずれ量に応じた突出高さを有する。突出部4aの突出高さと突出部4bの突出高さは同一である。ここで、突出部4aの突出高さとは、凹部5aにおける凸部6a側の端部の高さ位置、すなわち、凹部5aの上端の高さ位置から、突出部4aの頂点の高さ位置までの鉛直方向の距離である。また、突出部4bの突出高さとは、凹部5bにおける凸部6b側の端部の高さ位置、すなわち、凹部5bの下端の高さ位置から、突出部4bの頂点の高さ位置までの鉛直方向の距離である。 The protrusion 4a has a protrusion height that corresponds to the amount of deviation between the recess 5a and the protrusion 6a, and the protrusion 4b has a protrusion height that corresponds to the amount of deviation between the recess 5b and the protrusion 6b. The protrusion height of the protrusion 4a and the protrusion height of the protrusion 4b are the same. Here, the protrusion height of the protrusion 4a is defined as the height position of the end of the concave part 5a on the convex part 6a side, that is, from the height position of the upper end of the concave part 5a to the height position of the apex of the protrusion part 4a. This is the vertical distance. Furthermore, the protrusion height of the protrusion 4b is defined as the vertical distance from the height of the end of the recess 5b on the protrusion 6b side, that is, from the height of the lower end of the recess 5b to the height of the apex of the protrusion 4b. is the distance in the direction.

突出部4a,4bの頂点を含む稜線は、床材1の短辺又は長辺に沿って平行に形成される。突出部4aの稜線を間に挟んで、床材1の先端側は凸部6aの傾斜面であり、床材1の中間側は突出部4aに形成される係合面である。突出部4bの稜線を間に挟んで、床材1の先端側は凸部6bの傾斜面であり、床材1の中間側は突出部4bに形成される係合面である。これにより、基材2に形成される実は、突出部4aが突出部4bに引っ掛かりやすい構成を有している。 The ridgeline including the vertices of the protrusions 4a and 4b is formed parallel to the short side or long side of the flooring 1. With the ridgeline of the protruding part 4a in between, the tip side of the flooring 1 is the inclined surface of the convex part 6a, and the intermediate side of the flooring 1 is an engagement surface formed on the protruding part 4a. With the ridgeline of the protruding part 4b in between, the tip side of the flooring 1 is the inclined surface of the convex part 6b, and the intermediate side of the flooring 1 is an engagement surface formed on the protruding part 4b. As a result, the protrusion 4a formed on the base material 2 has a structure in which the protrusion 4a is easily caught on the protrusion 4b.

以上より、隣り合う床材1が実を介して組み合わされたとき、凹部5aと凸部6bが全面にわたって接触して嵌合し、凸部6aと凹部5bが全面にわたって接触して嵌合する。また、突出部4aと突出部4bが互いに係合する。その結果、隣り合う床材1の実同士が隙間なく組み合わされて、二つの床材1の表面が面一となる。 As described above, when adjacent flooring materials 1 are combined with each other through the joints, the recesses 5a and the projections 6b are in contact with each other over the entire surface and are fitted together, and the projections 6a and the recesses 5b are in contact with each other over the entire surface and are fitted together. Further, the protrusion 4a and the protrusion 4b engage with each other. As a result, the pieces of adjacent flooring materials 1 are combined without any gaps, and the surfaces of the two flooring materials 1 become flush.

凹部5a,凸部6a,凹部5b及び凸部6bの傾斜面の傾斜角度は、例えば、基材2の裏面側の板面に対して20度以上70度以下である。凹部5a,凸部6a,凹部5b及び凸部6bの傾斜角度が20度未満である場合、実の先端部が鋭角になり過ぎて厚さの薄い領域が多くなるため、運搬や施工の際に破損しやすくなる。他方、凹部5a,凸部6a,凹部5b及び凸部6bの傾斜角度が70度を超える場合、傾斜が急であることから、傾斜が緩やかな場合と比べて、実を平面視したときの実の幅(実の領域の面積)が小さい。そのため、施工時において突出部4a,4b同士を確実に係合できず、床材1同士を正しく接合できないおそれがあり、床材1の敷設作業が困難になる。また、凸部6a,6bの傾斜角度が70度を超える場合、突出部4a,4bの係合面の傾斜角度が90度に近いとき、突出部4a,4bの先端が鋭くなり突出部4a,4bが破損しやすくなる。例えば、凸部6a,6bの傾斜面の傾斜角度が75度である場合、突出部4a,4bの係合面の傾斜角度が60度を超えると、凸部6a,6bの傾斜面と突出部4a,4bの係合面のなす角が45度未満になる。 The angle of inclination of the slopes of the recesses 5a, the protrusions 6a, the recesses 5b, and the protrusions 6b is, for example, 20 degrees or more and 70 degrees or less with respect to the plate surface on the back side of the base material 2. If the inclination angle of the concave portions 5a, convex portions 6a, concave portions 5b, and convex portions 6b is less than 20 degrees, the tips of the fruits will be too acute and there will be many thin areas, making it difficult to Becomes easily damaged. On the other hand, when the inclination angle of the concave portion 5a, convex portion 6a, concave portion 5b, and convex portion 6b exceeds 70 degrees, the inclination is steep, and the fruit when viewed from the top is The width (area of the actual area) is small. Therefore, during construction, the protrusions 4a and 4b cannot be reliably engaged with each other, and there is a possibility that the flooring materials 1 cannot be properly joined together, making the work of laying the flooring material 1 difficult. Further, when the inclination angle of the protrusions 6a, 6b exceeds 70 degrees, when the inclination angle of the engagement surfaces of the protrusions 4a, 4b is close to 90 degrees, the tips of the protrusions 4a, 4b become sharp, and the protrusions 4a, 4b become sharp. 4b becomes easily damaged. For example, when the inclination angle of the sloped surfaces of the convex parts 6a, 6b is 75 degrees, if the inclination angle of the engagement surfaces of the protrusions 4a, 4b exceeds 60 degrees, the slopes of the convex parts 6a, 6b and the protrusion The angle formed by the engaging surfaces of 4a and 4b is less than 45 degrees.

突出部4a及び突出部4bの突出高さは、例えば、0.5mm以上2.5mm以下である。突出高さが0.5mm未満である場合、突出部4a,4bの強度が不十分となるため破損しやすくなり、また、突出部4aと突出部4bの係合が外れやすくなる。その結果、隣り合う床材1同士の継目に目隙が生じるおそれがある。他方、突出高さが2.5mmを超える場合、突出部4a,4bの先端が運搬や施工の際に作業者や他の物品に引っ掛かりやすくなり破損するおそれがある。 The protrusion height of the protrusion 4a and the protrusion 4b is, for example, 0.5 mm or more and 2.5 mm or less. If the protrusion height is less than 0.5 mm, the protrusions 4a and 4b will not have sufficient strength and will be easily damaged, and the protrusions 4a and 4b will easily disengage. As a result, there is a possibility that gaps may occur at the joints between adjacent flooring materials 1. On the other hand, if the protrusion height exceeds 2.5 mm, the tips of the protrusions 4a, 4b are likely to be caught by workers or other objects during transportation or construction, and there is a risk of damage.

図4及び図5に示すように、突出部4a及び突出部4bの係合面の傾斜角度は、例えば、基材2の裏面側の板面(水平線)に対して15度以上90度以下である。傾斜角度が15度未満である場合、突出部4aと突出部4bの係合が外れやすくなる。その結果、隣り合う床材1同士の継目に目隙が生じるおそれがある。他方、傾斜角度が90度を超える場合、突出部4a,4bを形成する際の切削加工が困難になり、先端が鋭角となるため破損しやすくなる。 As shown in FIGS. 4 and 5, the inclination angle of the engagement surfaces of the protrusion 4a and the protrusion 4b is, for example, 15 degrees or more and 90 degrees or less with respect to the plate surface (horizontal line) on the back side of the base material 2. be. When the inclination angle is less than 15 degrees, the protrusion 4a and the protrusion 4b tend to disengage. As a result, there is a possibility that gaps may occur at the joints between adjacent flooring materials 1. On the other hand, if the inclination angle exceeds 90 degrees, cutting when forming the protrusions 4a, 4b becomes difficult, and the tips become acute, making them more likely to be damaged.

次に、図7を参照して、本実施形態に係る床材1の施工方法について説明する。
まず、床下地材又は既存の床材の表面における汚れや塵埃を取り除いておく。
床材1を接着剤を用いて床下地材上又は既存の床材上に敷設する場合、床材1の裏面に接着剤を塗布する。その後、接着剤が塗布された床材1を床下地材上又は既存の床材上に配置して、床材1を接着させる。
Next, with reference to FIG. 7, a method for constructing the flooring material 1 according to the present embodiment will be described.
First, remove dirt and dust from the surface of the subfloor material or existing floor material.
When laying the flooring material 1 on a subfloor material or an existing flooring material using an adhesive, the adhesive is applied to the back surface of the flooring material 1. Thereafter, the flooring material 1 coated with the adhesive is placed on the subfloor material or on the existing flooring material, and the flooring material 1 is bonded.

次に、別の床材1について、裏面に接着剤を塗布し、図7(a)及び図7(b)に示すように、既に配置された床材1の隣に、新たに接着剤が塗布された床材1を床下地材上又は既存の床材上に配置して接着させる。このとき、図7(c)に示すように、突出部4aが突出部4bに引っ掛かるように、凹部5aを凸部6bに接触させ、凸部6aを凹部5bに接触させて配置する。 Next, adhesive is applied to the back side of another flooring material 1, and as shown in FIGS. 7(a) and 7(b), a new adhesive is applied next to the already placed flooring material 1. The applied floor material 1 is placed on a subfloor material or an existing floor material and bonded. At this time, as shown in FIG. 7C, the recess 5a is placed in contact with the protrusion 6b, and the protrusion 6a is placed in contact with the recess 5b so that the protrusion 4a is caught on the protrusion 4b.

床材1において予め吸着材3又は粘着剤(例えば両面テープ)が設けられている場合、床材1の裏面に貼付された離型紙を剥がし、吸着材3又は粘着剤を露出させる。その後、吸着材3又は粘着剤が露出した床材1を床下地材上又は既存の床材上に配置して、床材1の表面側から押圧しつつ床材1を付着させる。 When the adsorbent 3 or adhesive (for example, double-sided tape) is previously provided on the flooring 1, the release paper affixed to the back side of the flooring 1 is peeled off to expose the adsorbent 3 or the adhesive. Thereafter, the flooring material 1 with the adsorbent 3 or the adhesive exposed is placed on the subfloor material or on the existing flooring material, and the flooring material 1 is adhered while being pressed from the surface side of the flooring material 1.

次に、別の床材1について、裏面に貼付された離型紙を剥がし、図7(a)及び図7(b)に示すように、既に配置された床材1の隣に、新たに吸着材3又は粘着剤を露出させた床材1を床下地材上又は既存の床材上に配置して付着させる。このとき、図7(c)に示すように、突出部4aが突出部4bに引っ掛かるように、凹部5aを凸部6bに接触させ、凸部6aを凹部5bに接触させて配置する。 Next, remove the release paper affixed to the back of another flooring material 1, and as shown in FIGS. The material 3 or the flooring material 1 with exposed adhesive is placed and attached on the subfloor material or the existing flooring material. At this time, as shown in FIG. 7C, the recess 5a is placed in contact with the protrusion 6b, and the protrusion 6a is placed in contact with the recess 5b so that the protrusion 4a is caught on the protrusion 4b.

なお、吸着材3による吸着性を高めるため、床下地材は、表面が平滑な材質であることが望ましい。床下地材は、例えばコンクリート、金属、合成樹脂、アルミ箔貼りの発泡スチロールなどである。また、床下地材上又は既存の床材上に合成樹脂を塗布又は合成樹脂シートを貼付することによって、表面を平滑にしてもよい。 Note that, in order to enhance the adsorption ability of the adsorbent 3, it is desirable that the flooring material is made of a material with a smooth surface. Examples of flooring materials include concrete, metal, synthetic resin, and styrofoam covered with aluminum foil. Alternatively, the surface may be made smooth by applying a synthetic resin or pasting a synthetic resin sheet onto the subfloor material or existing floor material.

次に、図6を参照して、本実施形態に係る床材1の基材2に形成される実の変形例について作成する。
上述した実施形態では、突出部4a,4bに形成される係合面が水平線に対して90度であるが、本発明はこの例に限定されず、図6(a)~図6(c)に示すように、突出部4a,4bに形成される係合面は、水平線に対して90度未満でもよい。
Next, with reference to FIG. 6, a modification example of the material formed on the base material 2 of the floor material 1 according to the present embodiment will be created.
In the embodiment described above, the engagement surfaces formed on the protrusions 4a and 4b are at 90 degrees with respect to the horizontal line, but the present invention is not limited to this example, and as shown in FIGS. 6(a) to 6(c) As shown in , the engagement surfaces formed on the protrusions 4a and 4b may be less than 90 degrees with respect to the horizontal line.

また、上述した実施形態では、凹部5a,凸部6a,凹部5b及び凸部6bの傾斜面の傾斜角度が水平線に対して約30度であるが、本発明はこの例に限定されず、図6(a)に示すように、30度未満でもよいし、図6(b)及び図6(c)に示すように、45度より大きくてもよい。 Further, in the embodiment described above, the inclination angle of the inclined surfaces of the recess 5a, the convex part 6a, the concave part 5b, and the convex part 6b is about 30 degrees with respect to the horizontal line, but the present invention is not limited to this example. As shown in FIG. 6(a), the angle may be less than 30 degrees, or as shown in FIGS. 6(b) and 6(c), it may be greater than 45 degrees.

さらに、上述した実施形態では、凸部6aの傾斜面と突出部4aに形成される係合面が交わる部分や、凹部5aの傾斜面と突出部4aに形成される係合面が交わる部分において、屈曲形状、すなわち、断面が角形状を有する場合について示したが、本発明はこの例に限定されない。図6(b)に示すように、上記部分において、例えば円弧のような湾曲形状を有してもよい。 Furthermore, in the embodiment described above, in the portion where the slope of the convex portion 6a and the engagement surface formed on the protrusion 4a intersect, and the portion where the slope of the recess 5a and the engagement surface formed on the protrusion 4a intersect, , a bent shape, that is, a case where the cross section has an angular shape has been shown, but the present invention is not limited to this example. As shown in FIG. 6(b), the above portion may have a curved shape such as a circular arc, for example.

またさらに、上述した実施形態では、隣り合う床材1が組み合わされたとき、床材1の表面又は裏面において、二つの床材1が密着する場合について説明したが、本発明はこの例に限定されず、図6(b)に示すように、側端部の先端が切断された形状、すなわち、表面側から下方に向かう傾斜面7、又は、裏面側から上方に向かう傾斜面7が設けられてもよい。この場合、隣り合う床材1が組み合わされたとき、床材1の表面又は裏面において、床材1同士の間に目地が形成される。なお、傾斜面7は、表面側又は裏面側の一方のみに形成されてもよい。 Furthermore, in the embodiment described above, a case has been described in which when adjacent flooring materials 1 are combined, the two flooring materials 1 are in close contact with each other on the front or back surfaces of the flooring materials 1, but the present invention is limited to this example. Instead, as shown in FIG. 6(b), the tip of the side end is cut off, that is, an inclined surface 7 directed downward from the front surface side or an inclined surface 7 directed upward from the rear surface side is provided. You can. In this case, when adjacent flooring materials 1 are combined, joints are formed between the flooring materials 1 on the front or back surfaces of the flooring materials 1. Incidentally, the inclined surface 7 may be formed only on either the front side or the back side.

また、上述した実施形態では、隣り合う床材1の対向する実同士が組み合わされると、点対称となるように両側端部の実が形成される場合、すなわち、突出部4a,4bが床材1の高さ方向のほぼ中間に形成される場合について説明したが、本発明はこの例に限定されない。例えば、図6(d)に示すように、突出部4a,4bが床材1の裏面側に形成されてもよいし、図6(e)に示すように、突出部4a,4bが床材1の表面側に形成されてもよい。 Further, in the above-described embodiment, when the opposing nuts of the adjacent flooring materials 1 are combined, the nuts at both end portions are formed point-symmetrically, that is, the protrusions 4a and 4b of the flooring material Although the case has been described in which it is formed approximately in the middle in the height direction of 1, the present invention is not limited to this example. For example, as shown in FIG. 6(d), the protrusions 4a, 4b may be formed on the back side of the flooring 1, or as shown in FIG. 6(e), the protrusions 4a, 4b may be formed on the back side of the flooring 1. It may be formed on the surface side of 1.

以上、本実施形態によれば、突出部4aと突出部4bが互いに係合することから、複数の床材1が設置された後、それぞれの基材2が乾燥して収縮しようとする場合において、基材2の収縮が互いに拘束され合う。その結果、複数の床材1を新規に敷設する場合において、本実施形態に係る突出部4aと突出部4bが設けられていない床材と異なり、隣り合う床材1同士の間(継ぎ目)を可能な限り小さくしたり、隙間(目隙)を低減したりすることができる。 As described above, according to the present embodiment, since the protruding parts 4a and the protruding parts 4b engage with each other, even when each base material 2 dries and shrinks after a plurality of flooring materials 1 are installed, , the shrinkage of the base material 2 is constrained to each other. As a result, when newly laying a plurality of flooring materials 1, unlike the flooring material in which the protruding portions 4a and the protruding portions 4b according to the present embodiment are not provided, the spaces (seams) between adjacent flooring materials 1 are The gap can be made as small as possible or the gap (gap) can be reduced.

また、突出部4aが突出部4bに引っ掛かる構成を有していることから、床材1の施工時において突出部4aを突出部4bに引っ掛けて新たに敷設する床材1の位置決めをすることができる。本実施形態に係る突出部4aと突出部4bが設けられていない床材では、床材同士の側端部を突き合わせて位置決めした後、固定されていない状態で、床材1を配置していく必要がある。そのため、敷設作業中において床材の位置がずれやすく、継ぎ目に目隙が生じた状態で固定されてしまうおそれがある。本実施形態によれば、床材1に形成された実によって位置決めをしながら床材1を配置できるため、床材同士の継目に目隙を生じさせることなく、容易に床材1の敷設作業を行うことができ、作業時間の短縮化を図ることも可能である。 In addition, since the protrusion 4a is configured to be caught on the protrusion 4b, when installing the flooring 1, it is possible to hook the protrusion 4a on the protrusion 4b to position the newly laid flooring 1. can. In the case of the flooring material according to the present embodiment in which the protrusion part 4a and the protrusion part 4b are not provided, the side edges of the flooring materials are butted against each other for positioning, and then the flooring material 1 is placed in an unfixed state. There is a need. Therefore, the position of the flooring material is likely to shift during the installation work, and there is a risk that the flooring material will be fixed with gaps in the joints. According to this embodiment, the flooring material 1 can be placed while being positioned using the nuts formed on the flooring material 1, so that the laying work of the flooring material 1 can be easily performed without creating gaps in the joints between the flooring materials. It is also possible to shorten the working time.
