Description

本発明は、フローリング用板材に関するものである。   The present invention relates to a flooring plate.

従来、図(a)に示すように、相互に隣接する一方の板材111aに単一の凹溝部(雌実)112を形成すると共に、他方の板材111bに単一の凸条部(雄実)113を形成したフローリング用板材114が知られている。フローリング用板材114を施工する際には、凸条部113の基端部上側から下地材に釘115等を打ち込んで板材111bを下地材に固定すると共に、図(a)に仮想線で示すように、板材111aの凹溝部112を板材111bの凸条部113に噛合させることにより、板材111a,111bを突き合わせた状態で接合する。 Conventionally, as shown in FIG. 4 (a), a single concave groove (female) 112 is formed on one plate material 111a adjacent to each other, and a single ridge (male) is formed on the other plate material 111b. ) 113 is known. When applying a flooring plate 114 fixes the plate member 111b to the underlying material by implanting a nail 115 or the like from the base end part upper ridge portions 113 in the base member, shown in phantom in FIGS. 4 (a) In this manner, the concave groove portion 112 of the plate material 111a is engaged with the convex strip portion 113 of the plate material 111b, so that the plate materials 111a and 111b are joined in a state of abutting each other.

前記フローリング用板材114は施工直後には整然とした接合状態を呈するものの、経時的に含水率が変化すると、収縮あるいは膨張し、接合部116に問題を生じる。即ち、前記フローリング用板材114は乾燥した環境下では含水率の低下により、図(b)に矢示するように収縮して接合部116に間隙Sを生じ、間隙Sに堆積した埃や釘115等が露見して美観を損ねる。一方、前記フローリング用板材114は高湿度の環境下では含水率の増加により膨張し、図(c)に矢示するように接合部116が水平面Lから浮き上がる突き上げ117を生じ、美観を損ねるばかりか、歩行の障害となることもある。前記接合部116に生じる問題は、特に床暖房を行う場合に顕著である。 Although the flooring plate material 114 exhibits an orderly joined state immediately after construction, when the moisture content changes with time, it contracts or expands, causing a problem in the joint portion 116. That is, by lowering the water content in an environment that is the flooring plate 114 and dried, resulting a gap S to contract and junction 116 to arrow in FIG. 4 (b), dust and nails deposited in the gap S 115 is exposed and the beauty is lost. On the other hand, the flooring plate 114 expands due to an increase in moisture content in a high humidity environment, and as shown in FIG. 4 (c), the joining portion 116 is lifted up from the horizontal plane L, resulting in a loss of aesthetics. Or it may be an obstacle for walking. The problem occurring in the joint 116 is particularly noticeable when floor heating is performed.

そこで、前記木材の膨張により生じる接合部116の突き上げ117を防止するために、前記接合部116に予め間隙を設けておき、該膨張を吸収するようにすることが考えられる。ところが、前記接合部116に予め間隙を設けると、釘115により固定されていない凹溝部112側でガタツキや段差が生じやすい。   Therefore, in order to prevent the pushing-up 117 of the joint 116 caused by the expansion of the wood, it is conceivable to provide a gap in the joint 116 in advance to absorb the expansion. However, if a gap is provided in the joint 116 in advance, rattling or a step is likely to occur on the side of the concave groove 112 that is not fixed by the nail 115.

前記接合部116に予め間隙を設ける場合の前記問題を解決するために、例えば、図(a)に示すように、板材121aに単一の凹溝部122を形成すると共に、板材121bに単一の凸条部123を形成したフローリング用板材124において、板材121bの凸条部123の上側に、凸条部123の先端部から板材121bの表面に向けて次第に隆起する傾斜面125aを形成すると共に、板材121aの凹溝部122の上側に、傾斜面125aに対応する形状を備え凹溝部122の基端部と板材121aの表面とを接続する傾斜面125bを形成したものが提案されている(例えば特許文献1参照)。 Single in order to solve the problems of the case where the pre-gap to the junction 116, for example, as shown in FIG. 5 (a), thereby forming a single concave groove 122 in plate 121a, the plate member 121b In the flooring plate member 124 having the ridges 123 formed thereon, an inclined surface 125a that gradually rises from the tip of the ridges 123 toward the surface of the plate member 121b is formed above the ridges 123 of the plate member 121b. In addition, a structure has been proposed in which an inclined surface 125b having a shape corresponding to the inclined surface 125a and having a shape corresponding to the inclined surface 125a and connecting the base end portion of the recessed groove portion 122 and the surface of the plate material 121a is formed above the recessed groove portion 122 of the plate material 121a (for example, Patent Document 1).

前記フローリング用板材124は、凹溝部122の下面126から下地材に釘127等を打ち込むことにより、板材121aが下地材に固定される。また、図(a)に仮想線示するように、板材121a,121bを接合したときに、凹溝部122の下面126の先端部126aと、凸条部123の基端部123aとの間に間隙Sが形成されるようになっている。前記フローリング用板材124は、板材121a,121bを接合したときには、傾斜面125a,125bが密着するので、板材121a,121bを水平方向、垂直方向共にガタツキ無く緊密に接合できるとされている。 The flooring plate 124 is fixed to the base material 121 by driving a nail 127 or the like into the base material from the lower surface 126 of the concave groove 122. Further, the virtual line Shimesuru so in FIG. 5 (a), the plate member 121a, when joining the 121b, and the distal end portion 126a of the lower surface 126 of the groove portion 122, between the base end portion 123a of the ridge 123 A gap S is formed. When the plate materials 121a and 121b are joined to the flooring plate material 124, the inclined surfaces 125a and 125b are in close contact with each other, so that the plate materials 121a and 121b can be tightly joined in the horizontal and vertical directions without backlash.

しかしながら、前記フローリング用板材124は、図(b)に矢示するように、板材121bが板材121a方向に食い込み過ぎると、楔状の凸条部123が凹溝部122に圧入されて凹溝部122上側の傾斜面125bの先端128が上方に捲れ上がるという不都合がある。また、板材121a,121bの接合が緩いと、図(c)に矢示するように、固定されていない凸条部123が浮き上がり接合部129に段差130が形成されるという不都合がある。 However, the flooring plate 124, and FIG. 5 (b) in such that arrow, the plate member 121b is too bite plate material 121a direction, convex portion 123 is recessed groove portion 122 is press-fitted into and recessed groove 122 upper wedge There is an inconvenience that the tip 128 of the inclined surface 125b is rolled up. Further, when the plate 121a, the junction of 121b is loose, so that arrow in FIG. 5 (c), the junction 129 ridges 123 lift not fixed is disadvantageously step 130 is formed.

一方、前記木材の膨張により図(b)に示す接合部116に間隙Sを生じる問題を解決するために、図(a)に示すように、板材131aに単一の凹溝部132を形成すると共に、板材131bに単一の凸条部133を形成したフローリング用板材134において、板材131bの凸条部133の基端部上側から板材131bの表面に向けて次第に隆起する傾斜面135aを形成すると共に、傾斜面135aに対応する形状を備え板材131aの凹溝部132の先端部と板材131aの表面とを接続する傾斜面135bを形成したものが提案されている(例えば特許文献2参照)。 Meanwhile, in order to solve the problems caused the gap S to the junction 116 shown in FIG. 4 (b) due to the expansion of the timber, as shown in FIG. 6 (a), a single groove 132 in plate 131a formed At the same time, in the flooring plate 134 in which the single ridge 133 is formed on the plate 131b, an inclined surface 135a that gradually rises from the upper side of the base end of the ridge 133 of the plate 131b toward the surface of the plate 131b is formed. In addition, there has been proposed an inclined surface 135b that has a shape corresponding to the inclined surface 135a and that connects the tip of the concave groove 132 of the plate member 131a and the surface of the plate member 131a (see, for example, Patent Document 2).

前記フローリング用板材134によれば、図(b)に矢示するように、板材131a,131bが収縮しても、傾斜面135bが傾斜面135aの上方に位置しているので、凸条部133の上側基端部から下地材に打ち込まれた釘136等が露見することがなく、また接合部137に生じる間隙Sを目立たなくすることができるとされている。 According to the flooring plate 134, as indicated by arrows in FIG. 6 (b), the plate member 131a, even 131b is contracted, since the inclined surface 135b is located above the inclined surfaces 135a, ridges The nail 136 or the like driven into the base material from the upper base end portion 133 is not exposed, and the gap S generated in the joint portion 137 can be made inconspicuous.

しかしながら、前記フローリング用板材134は、膨張したときには、図(c)に矢示するように、接合部137が水平面Lから浮き上がる突き上げ138を生じるという不都合がある。

In the flooring board material which butt | joins and joins both board | plate materials by meshing the convex strip part of 2 board | plate materials, it is provided with the 1st board | plate material provided with several recessed groove part, and the several projected line part meshed | engaged with each recessed groove part. A first inclined surface connected to the surface of the plate material and inclined at an angle in a range of 15 to 60 degrees from the surface side toward the back surface side of the plate material. A second inclined surface connected to the first inclined surface and inclined in the same direction as the first inclined surface from the surface side of the plate material toward the back surface side of the plate material at an angle in the range of 5 to 45 °. A first groove portion formed by the upper space, first and second inclined surfaces, and a surface of the plate member facing the both inclined surfaces. A first protrusion formed by a portion sandwiched between a first inclined surface and a third inclined surface inclined at an angle in the range of 5 to 45 ° in the opposite direction from the first inclined surface toward the back surface side of the plate member. Part, a third inclined surface, and an angle in a range of 5 to 45 ° in the same direction as the first inclined surface from the front surface side of the plate material toward the back surface side of the plate material, facing the third inclined surface. The second concave groove formed by the space sandwiched between the inclined fourth inclined surface, the fourth inclined surface, and the fourth inclined surface from the front surface side of the plate material to the back surface side of the plate material A second protrusion formed by a portion sandwiched between a first inclined surface and a fifth inclined surface inclined at an angle in the range of 5 to 45 ° in the opposite direction to the first inclined surface; A second grooved portion formed by a lower space, and the second plate member includes a surface of the plate member and a first inclined surface from the surface side of the plate member toward the back side of the plate member. A sixth inclined surface that is inclined in the same direction at a smaller angle than the first inclined surface, and a sixth inclined surface that is connected to the sixth inclined surface and faces from the front surface side of the plate material toward the back surface side of the plate material A third ridge portion formed by a portion sandwiched by a seventh inclined surface inclined at a smaller angle than the second inclined surface in the same direction as the second inclined surface, and meshed with the first concave groove portion, The seventh inclined surfaces and the both inclined surfaces are inclined at an angle in the range of 5 to 45 ° in the direction opposite to the sixth inclined surface from the front surface side of the plate material toward the back surface side of the plate material. A surface of the plate member that is formed by a space sandwiched between the eighth inclined surface and that opposes the fourth inclined groove portion, the eighth inclined surface, and the eighth inclined surface. Formed by a portion sandwiched between a sixth inclined surface and a ninth inclined surface inclined at an angle in the range of 5 to 45 ° in the same direction from the side toward the back surface side of the plate member, A fourth ridge portion meshed with the concave groove portion, a ninth inclined surface, and a direction opposite to the sixth inclined surface facing the inclined surface from the surface side of the plate material toward the back surface side of the plate material And a tenth inclined surface formed by a space sandwiched between the tenth inclined surface inclined at an angle in the range of 5 to 45 °, and the second convex groove portion meshing with the tenth inclined surface, It is formed by a portion sandwiched between the back surface of the plate material, extends in the width direction of the plate material with a length in the range of 4 to 25 mm from the tip end portion of the fourth convex strip portion, and meshes with the third concave groove portion. 5th ridge part, and a 5th ridge part is equipped with the thickness of the range of 1/5-1/2 of this board | plate material in the front-end | tip part, It is characterized by the above-mentioned.

本発明のフローリング用板材によれば、第1の板材の端部に形成された複数の凹溝部を、第2の板材の端部に形成された複数の凸条部に噛合させるので、水平方向、垂直方向共にガタツキが無く、段差も無い整然とした接合部を形成することができる。   According to the plate material for flooring of the present invention, the plurality of concave groove portions formed at the end portion of the first plate material are meshed with the plurality of ridge portions formed at the end portion of the second plate material. Therefore, it is possible to form an orderly joined portion having no backlash in the vertical direction and no step.

ところで、フローリング用板材は、厚さが3〜30mm程度と薄いため、その端部に複数の凹溝部、凸条部を形成すると、所望の強度が得られないことがある。例えば、図に示すように、端部に複数の凹溝部101a、101bを備える第1の板材102aと、端部に複数の凸条部103a、103bを備える第2の板材102bとを、凹溝部101a、101bを凸条部103a、103bに噛合させて接合する際に、凸条部103aの基端部から下地材に釘104を打ち込むと、該凸条部103aが折れたり、割れたりする。 By the way, since the board | plate material for flooring is as thin as about 3-30 mm, when a several groove part and a protruding item | line part are formed in the edge part, desired intensity | strength may not be acquired. For example, as shown in FIG. 3 , a first plate member 102a having a plurality of recessed groove portions 101a and 101b at an end portion and a second plate member 102b having a plurality of protruding strip portions 103a and 103b at an end portion are recessed. When the grooves 101a and 101b are engaged with and joined to the ridges 103a and 103b, if the nail 104 is driven into the base material from the base end of the ridge 103a, the ridge 103a is broken or broken. .

そこで、本発明のフローリング用板材において、第1の板材は前記第1及び第2の傾斜面を備え、第1の板材の前記凹溝部の1つは、第1及び第2の傾斜面の上側の空間により形成されており、第2の板材は前記第6及び第7の傾斜面を備え、第2の板材の前記凸条部の1つは、該板材の表面と第6及び第7の傾斜面とに挟まれる部分により形成されている。前記構成とすることにより、第1の傾斜面の下側の部分の強度を確保することができる。 Therefore, in the flooring plate of the present invention, the first plate has the first and second inclined surfaces, and one of the concave groove portions of the first plate is above the first and second inclined surfaces. The second plate member is provided with the sixth and seventh inclined surfaces, and one of the convex strips of the second plate member is formed on the surface of the plate member and the sixth and seventh surfaces . It is formed by a portion sandwiched between inclined surfaces. By setting it as the said structure, the intensity | strength of the lower part of a 1st inclined surface is securable.

また、本発明のフローリング用板材では、第2の板材の表面と第6及び第7の傾斜面とに挟まれる部分により形成される前記凸条部が、第1の板材の第1及び第2の傾斜面の上側の空間により形成された凹溝部に噛合されて接合部を形成する。従って、第1及び第2の傾斜面の上側には第6及び第7の傾斜面を備える前記凸条部があり、第1、第2の板材が経時的に収縮して前記接合部に間隙が生じたとしても、該間隙を目立たなくすることができる。 Moreover, in the board | plate material for flooring of this invention, the said protruding item | line part formed of the part pinched | interposed into the surface of the 2nd board | plate material and the 6th and 7th inclined surface is 1st and 2nd of the 1st board | plate material . The joint is formed by meshing with a groove formed by the space above the inclined surface. Accordingly, the convex strips having the sixth and seventh inclined surfaces are provided above the first and second inclined surfaces, and the first and second plate members shrink with time, and the gaps are formed in the joints. Even if this occurs, the gap can be made inconspicuous.

また、本発明のフローリング用板材では、第6及び第7の傾斜面は、第1及び第2の傾斜面よりも板材表面に対する角度が小さく形成されているので、第2の板材の表面と第6及び第7の傾斜面とに挟まれる部分により形成される前記凸条部が、第1の板材の第1及び第2の傾斜面の上側の空間により形成される前記凹溝部に噛合されたときに、少なくとも第1及び第2の傾斜面と、第6及び第7の傾斜面との間に間隙が形成される。従って、第1、第2の板材が経時的に膨張したときには、前記間隙により該膨張を吸収することができ、前記接合部に突き上げが生じることを防止することができる。 In the flooring plate of the present invention, the sixth and seventh inclined surfaces are formed with a smaller angle with respect to the plate surface than the first and second inclined surfaces . The ridge portion formed by the portion sandwiched between the sixth and seventh inclined surfaces is meshed with the concave groove portion formed by the space above the first and second inclined surfaces of the first plate member. when the at least first and second inclined surfaces, a gap is formed between the sixth and seventh inclined surface. Therefore, when the first and second plate materials expand over time, the expansion can be absorbed by the gap, and the joint can be prevented from being pushed up.

また、本発明のフローリング用板材によれば、第5の凸条部の上面であり、第4の凸条部の先端部から4〜25mmの範囲の長さで該板材の幅方向に延在する第10の傾斜面を、下地材に釘を打ち込む釘打ち部として利用することができる。ここで、第5の凸条部は、その先端部が第1の板材の1/5〜1/2の範囲の厚さを備えるので、基端部側ではさらに厚くなり、前記釘打ち部として十分な強度を確保することができる。また、第5の凸条部は、その先端部が前記範囲の厚さを備えるので、他の凸条部の強度を確保する上で有利である。 Moreover, according to the board | plate material for flooring of this invention, it is the upper surface of the 5th protruding item | line part, and is extended in the width direction of this plate | board material by the length of the range of 4-25 mm from the front-end | tip part of a 4th protruding item | line part. The tenth inclined surface to be used can be used as a nail driving portion for driving a nail into the base material. Here, since the tip of the fifth ridge is provided with a thickness in the range of 1/5 to 1/2 of that of the first plate material, it becomes thicker on the base end side, Sufficient strength can be ensured. Moreover, since the 5th protruding item | line part has the thickness of the said range, the front-end | tip part is advantageous when ensuring the intensity | strength of another protruding item | line part.

第5の凸条部は、その先端部が第1の板材の1/5未満の厚さでは、基端部側でも釘打ち部として所要の強度が得られないことがあり、1/2を超える厚さとすると、第4の凸条部等の他の構成に所要の強度を確保できなくなることがある。また、第5の凸条部は、第4の凸条部の先端部から第1の板材の幅方向に延在する部分の長さが4mm未満ではこの部分に釘を打ちにくく、また25mmを超える長さとしてもそれ以上の効果は得られない。   If the tip of the fifth ridge is less than 1/5 of the thickness of the first plate, the required strength may not be obtained as a nailing portion on the base end side. If the thickness is greater, the required strength may not be ensured for other configurations such as the fourth ridge. Further, if the length of the portion extending in the width direction of the first plate material from the tip portion of the fourth ridge portion is less than 4 mm, the fifth ridge portion is difficult to nail this portion, and 25 mm Even if it exceeds the length, no further effect can be obtained.

また、前記構成のフローリング用板材によれば、第1の板材の端部に第1〜第3の凹溝部と、第1、第2の凸条部とを形成すると共に、第2の板材の端部に第4、第5の凹溝部と、第3〜第5の凸条部とを形成したので、第1、第2の板材をさらに緊密に接合することができ、該板材の厚さ方向のずれを低減することができる。また、前述のようにすることにより、位置矯正または位置決めする接点が増加するので、加工精度に対する許容度を増大させることができる。 Moreover, according to the board | plate material for flooring of the said structure, while forming the 1st-3rd recessed groove part and the 1st, 2nd protruding item | line part in the edge part of a 1st board | plate material, the the end 4, and a fifth groove section, since forms forms a convex portion of the third to fifth, it is possible to more tightly bond the first, second plate, of the plate member Deviation in the thickness direction can be reduced. Further, the to Rukoto As described above, since the contact point is increased to the position correction or positioning, it is possible to increase the tolerance to machining accuracy.

また、前記構成のフローリング用板材によれば、第1〜第5の凸条部をそれぞれ少なくとも1つの傾斜面により形成しているので該凸条部の先端が尖頭形状となり、第1〜第5の凸条部が第1〜第5の凹溝部の奥まで容易に進入することができる。従って、第1、第2の板材が膨張したときにも前記接合部に突き上げを生じ難くすることができる。このとき、第2の板材の第6〜第10の傾斜面の角度は、第1の板材の第1〜第5の傾斜面の角度よりも小さくされているので、第1の板材に形成されている第1、第2の凸条部が、第2の板材に形成されている第4、第5の凹溝部に深く侵入するほど、該凸条部の基端部が緊く締め付けられ、第1、第2の板材のガタツキを低減することができる。   Further, according to the flooring plate material having the above-described configuration, the first to fifth ridges are each formed by at least one inclined surface, so that the tips of the ridges have a pointed shape, and the first to first ridges are formed. The 5 ridges can easily enter the back of the first to fifth grooves. Therefore, even when the first and second plate members expand, it is possible to make it difficult for the joint portion to be pushed up. At this time, since the angles of the sixth to tenth inclined surfaces of the second plate material are made smaller than the angles of the first to fifth inclined surfaces of the first plate material, the second plate material is formed on the first plate material. The first and second ridges are deeply penetrated into the fourth and fifth grooves formed in the second plate material, and the proximal end of the ridge is tightened tightly, The backlash of the first and second plate materials can be reduced.

また、本発明のフローリング用板材において、第3の凸条部は、第1の凹溝部に噛合されたときに、第1の傾斜面との間に装飾溝部を形成する面取り部を備えるものであってもよい。前記第3の凸条部は、前記面取り部を備えることにより、前記装飾溝部を形成することができると共に、該面取り部が第1の傾斜面の途中に当接することになるので、各凸条部と各凹溝部との噛合の程度を規制して、第1、第2、第4の各凸条部の先端部と、第2〜第4の各凹溝部の基端部との間に間隙を確保することができる。この結果、前記構成のフローリング用板材によれば、第1、第2の板材が経時的に膨張したときに、その膨張をさらに有利に吸収することができる。   Moreover, in the board | plate material for flooring of this invention, a 3rd protruding item | line part is provided with the chamfering part which forms a decoration groove part between 1st inclined surfaces, when it meshes | engages with a 1st groove part. There may be. By providing the chamfered portion, the third ridge portion can form the decorative groove portion, and the chamfered portion abuts in the middle of the first inclined surface. The degree of meshing between the first groove portion and each concave groove portion, and between the distal end portions of the first, second, and fourth convex ridge portions and the base end portions of the second to fourth concave groove portions. A gap can be secured. As a result, according to the flooring plate having the above-described configuration, when the first and second plate members expand over time, the expansion can be more advantageously absorbed.

また、本発明のフローリング用板材において、前記第1、第2の板材は、それぞれ一方の端部に前記複数の凹溝部を備え、他方の端部に前記複数の凸状部を備えることが好ましい。前記構成のフローリング用板材によれば、1枚の板材の一方の端部に前記第1の板材としての機能を付与すると共に、他方の端部には前記第2の板材としての機能を付与することができる。   In the flooring plate of the present invention, it is preferable that each of the first and second plate members includes the plurality of concave groove portions at one end portion and the plurality of convex portions at the other end portion. . According to the flooring plate having the above-described configuration, the function as the first plate is given to one end of one plate, and the function as the second plate is given to the other end. be able to.

従って、一つのフローリング用板材の前記第1の板材としての機能を有する端部には、他のフローリング用板材の前記第2の板材としての機能を有する端部を接合し、前記第2の板材としての機能を有する端部には、さらに他のフローリング用板材の前記第1の板材としての機能を有する端部を接合するというようにして、同一形状の多数のフローリング用板材を相互に接合して連結することができる。   Therefore, the end portion having the function as the first plate member of one flooring plate is joined to the end portion having the function as the second plate member of the other flooring plate, and the second plate member is joined. A plurality of flooring plates having the same shape are joined to each other, such as joining the end portion of the other flooring plate functioning as the first plate material to the end portion having the function as Can be connected.

Since the thickness increases, it is possible to ensure sufficient strength as a nail driving portion by driving the nail 75 into a portion that is 1/4 or more of the thickness D of the plate member 42b. Then, the first ridge 49 and the second ridge 55 of the plate 42a are engaged with the fourth groove 65 and the fifth groove 71 of the plate 42b, respectively, and the third ridge 61 of the plate 42b.
