Description

本発明は、住宅その他に使用されるフローリングの素材として利用される床材であって、木製の従来の平板材ではなく竹製の板材を使用した耐久性のある床材の構造に関し、特に長板材の横幅方向の端面の一方に係合凸凹部と他方に嵌入凸凹部を設け、または、対抗する両側壁の一方に係合凸条と他方に凹溝とを設け、隣接する係合部同士を相互に係合して張り合わせる連結式の床材であって、相互に固定可能であったり下地材に強固に固定可能であったりする、外観、施工性に優れた平板床材に関する。   The present invention relates to a flooring material used as a material for flooring used in houses and the like, and relates to a durable flooring structure using a bamboo plate material instead of a conventional wooden flat plate material. An engagement convex recess is provided on one of the end surfaces in the width direction of the plate member and an insertion convex recess is provided on the other, or an engaging convex strip and a concave groove are provided on one of the opposing side walls, and adjacent engaging portions are The present invention relates to a flat flooring material excellent in appearance and workability that can be fixed to each other or firmly fixed to a base material.

平板部材の長手方向に沿って両側壁面に雄雌同形状の凸条と凹溝を設けて隣り合わせた平板部材を連結してフローリングを形成する方法が従来から採用されている。これらのフローリング部材としては従来から各種木材が使用されていたが、竹材を床材として利用する例はあまり知られていない。また、長板の長手方向の側壁を係合するのに替えて、横幅方向の端面に係合凸凹部を設けて連結することが考えられている。床材として竹を利用することは、竹を平板に成形する必要があるために、加工に手間がかかりコストがかかる欠点があったが、平板の矩形竹板材が開発されたので、加工も簡便となり、フローリング材としても使用が可能になった。近年、環境配慮の問題からも、生育速度に優れる竹材の活用に注目が集まりつつある。   2. Description of the Related Art Conventionally, a method of forming a flooring by connecting adjacent flat plate members by providing male and female ridges and grooves on both side wall surfaces along the longitudinal direction of the flat plate member has been employed. Conventionally, various kinds of wood have been used as these flooring members, but examples of using bamboo as a flooring are not well known. Further, instead of engaging the side wall in the longitudinal direction of the long plate, it is considered to provide an engaging convex concave portion on the end face in the lateral width direction for connection. The use of bamboo as a flooring material has the disadvantage that it is time consuming and costly because it is necessary to form bamboo into a flat plate. Thus, it can be used as a flooring material. In recent years, attention has been focused on the use of bamboo with excellent growth speed due to environmental concerns.

円筒の竹材を床材として利用するために、木材とは異なり、各種の工夫が必要となる。また、平板に形成しているが、形成できる幅の広さには限りがあるので、ある程度の幅で、多数枚の平板を連結する必要がある。連結の方法とその構造は木材の連結に使用される技術を応用している。
竹は縦割れしやすいという弱点があり、釘等の固定部材の打ち込みによる衝撃によって縦割れが生じる可能性がある。従って、竹材の施工においては、木材にない固定部材を嵌入させるための孔を予め穿設しておく等の配慮が必要となる。 In order to use a cylindrical bamboo material as a flooring material, various ideas are required unlike wood. Moreover, although it forms in a flat plate, since the width | variety which can be formed is limited, it is necessary to connect many flat plates with a certain amount of width. The connection method and its structure apply the technology used for connecting wood.
Bamboo has a weak point that it easily breaks vertically, and there is a possibility that vertical cracks may occur due to impact caused by driving of a fixing member such as a nail. Therefore, in the construction of bamboo material, it is necessary to consider such as making a hole for inserting a fixing member that is not on wood.

従来、住宅その他に使用される床材の構造は、図３に示すように床材を縦長板状に形成し、対抗する一対の側壁にその側壁に沿って互いに嵌合自在な凸部１２０および凹溝１３０が形成された構造を採用している。しかしながら、長板の横幅方向の端面に嵌合自在な凸部および凹溝１３０が形成された従来例はおおくは存在しない。
また、従来の床材を使用した施工方法として、主として釘で根太上に固定する方法、主として接着剤でコンクリートスラブや下地材上に固定する方法、両面テープ等（高密度のシートが使用される場合もある）で軽度に接着する方法があり、それぞれ一長一短がある。 Conventionally, a flooring structure used in a house or the like has a structure in which a flooring is formed in a vertically long plate shape as shown in FIG. A structure in which the concave groove 130 is formed is adopted. However, there are not many conventional examples in which a convex portion and a concave groove 130 that can be fitted to each other are formed on the end face of the long plate in the width direction.
In addition, as a construction method using a conventional flooring material, a method mainly fixing on a joist with a nail, a method mainly fixing on a concrete slab or a base material with an adhesive, a double-sided tape, etc. (a high-density sheet is used) In some cases, there is a method of slightly bonding, and each has advantages and disadvantages.

根太上に固定する施工例としては、床材を根太の上面に配置し、凸部１２０の上面から釘を根太に達するように斜めに打ち込んで床材を根太に固定する例がある。以後、固定された床材の凸部１２０に次の床材の凹溝１３０を嵌合させ、同様の工程で固定することで床材の張り合わせを行っている。
また、接着剤で固定する方法や両面テープ等で接着する方法の施工例は、下地材に接着剤を塗布し固定したり、両面テープ等で下地材に接着した上で、固定等された床材の凸部１２０に次の床材の凹溝１３０を嵌合させることで床材の張り合わせを行っている。 As an example of construction to be fixed on the joist, there is an example in which the flooring is arranged on the upper surface of the joist and the nail is driven obliquely from the upper surface of the convex portion 120 so as to reach the joist to fix the flooring to the joist. Thereafter, the floor material is stuck together by fitting the concave groove 130 of the next floor material to the convex portion 120 of the fixed floor material and fixing in the same process.
In addition, examples of construction using the method of fixing with an adhesive or the method of bonding with a double-sided tape, etc., apply the adhesive to the base material and fix it, or adhere to the base material with a double-sided tape etc. The floor material is laminated by fitting the concave groove 130 of the next floor material to the convex portion 120 of the material.

そのうち、釘で根太上に固定する方法は、強固であって、踏み鳴りの発生が比較的少ないという点で優れているが、その固定に釘が使用されるため、化粧面の損傷、釘の露出による外観の悪化、解体時の損傷等の問題点がある。また、接着剤で固定する方法は、釘を使用しないので、ハンマーで傷を付ける心配はないが、接着剤には有機溶剤を使用したものが多く、火炎の危険性があり換気等の対策が必要になる。また接着剤の硬化に時間を要するのでその間の取扱いには十分注意しなければならない。さらに、両面テープ等で軽度に接着する方法は、施工直後から歩行可能で特に養生時間は不要であるが、両面テープ等による軽度の接着にすぎないので、ずれて隙間を生じたり、踏み鳴りが生じやすい。   Among them, the method of fixing on the joist with a nail is excellent in that it is strong and the occurrence of trumbling is relatively low. There are problems such as deterioration of appearance due to exposure and damage during dismantling. In addition, the method of fixing with adhesive does not use nails, so there is no worry of scratching with a hammer, but many adhesives use organic solvents, there is a risk of flame, and measures such as ventilation are taken. I need it. Also, since it takes time to cure the adhesive, care must be taken during handling during that time. Furthermore, the method of lightly adhering with double-sided tape, etc. can be walked immediately after construction and does not require any curing time, but it is only lightly adhesive with double-sided tape, etc., so there is a gap and staggering. Prone to occur.

このような問題を解決しようとする手段として特許文献１があげられる。しかし、特許文献１に記載される手段では、床材の孔に固定部材を嵌入し、固定すると嵌入された固定部材の頭部が邪魔となり、床材の嵌合に齟齬が生じる可能性があった。また、竹材の弱点である縦割れの発生を防止するには十分とは言えない。そのため、依然としてずれや踏み鳴りが発生する可能性があり、ずれや踏み鳴りが生じ難い床材の構造であって、特に耐久性と生育速度に優れた竹材を用いた床材の改発が待たれていた。   Patent Document 1 is cited as a means for solving such a problem. However, with the means described in Patent Document 1, when the fixing member is inserted into the hole of the flooring and fixed, the head of the inserted fixing member becomes an obstacle, and there is a possibility that the fitting of the flooring may cause wrinkles. It was. Moreover, it cannot be said to be sufficient to prevent the occurrence of vertical cracks, which is a weak point of bamboo. Therefore, there is a possibility that slippage and trumbling may still occur, and it is a flooring structure that is difficult to cause slipping and trumbling, and it was awaited to renew the flooring using bamboo that is particularly durable and has a high growth rate. It was.

本発明に係る連結竹床材は、上述のような構造から、以下のような効果を有する。
１．矩形長板の横幅方向の端面に設けられた係合凸凹部と嵌入凸凹部とを嵌合させる構造なので、長手方向に整列した長板同士を堅固に固定することが可能で、下地材への強固な固定も可能にしている。長手方向の側面に加工する場合と比べ加工面積が少なくてすみ、歩留が良い。加えて、予め穿設してある孔に固定部材を打設するため、竹材に生じやすい縦割れを発生させることなく市販の釘やハンマーでの打設が可能であり、ピン打ち機等の特別の工具を使用しなくても施工することができる。
２．係合凸条の幅を広く成形しているので、配送時等に加わる衝撃によって破損を生じにくい。更に、係合凸条と嵌合する嵌入凹溝の幅も広く成形されるため嵌入凹溝に穿設された孔に固定部材を打設するにあたり、ハンマー等の工具が使用しやすい。また、係合凸条の頂面と凹溝の底面との間に適宜の空間が設けられているので、固定部材の頭部が多少上方に飛び出していてもこれを許容することができる。
３．矩形長板の対抗する両側壁に設けられた係合凸条と凹溝とを嵌合させて、溝に固定部材を打設するだけで簡便に竹のフローリングを構築することが可能である。
４．凹溝の凹部の深さを張出部の先端から５ｍｍ、延出部の長さを延出部の先端から１５ｍｍに形成することにより、溝部に固定部材を打設し易くしているので設置工事が比較的楽で、施工費用を削減できる。
５．凸条を正確に凹溝に嵌入する形状としているのでぴったりと嵌合して、接合床板の違和感がないという効果がある。
６．フローリングは細長い平板を使用するのが通常であるが、凸条と凹溝を長手方向だけでなく長手方向と直交する方向に設けることで、連結竹床材を長手方向と直交する方向へも連結することができ、必ずしも長い連結竹床材を用いる必要がなくなる。 The connected bamboo flooring according to the present invention has the following effects from the above-described structure.
1. Since it is a structure in which the engaging convexity and the fitting convexity provided on the end face in the width direction of the rectangular long plate are fitted, it is possible to firmly fix the long plates aligned in the longitudinal direction, and to the base material It can also be firmly fixed. Compared with the case of processing on the side surface in the longitudinal direction, the processing area is small and the yield is good. In addition, because the fixing member is driven in the hole that has been drilled in advance, it can be driven with a commercially available nail or hammer without causing vertical cracks that are likely to occur in bamboo. Construction can be done without using any tool.
2. Since the engaging ridges are formed with a wide width, they are less likely to be damaged by an impact applied during delivery. Further, since the width of the insertion groove to be fitted with the engagement protrusion is formed wide, it is easy to use a tool such as a hammer when placing the fixing member in the hole formed in the insertion groove. In addition, since an appropriate space is provided between the top surface of the engaging ridge and the bottom surface of the concave groove, this can be allowed even if the head of the fixing member protrudes slightly upward.
3. It is possible to construct a bamboo flooring simply by fitting engaging ridges and concave grooves provided on opposite side walls of a rectangular long plate and driving a fixing member into the groove.
4). By setting the depth of the concave portion of the concave groove to 5 mm from the tip of the overhanging portion and the length of the extending portion to 15 mm from the tip of the extending portion, it is easy to place a fixing member in the groove portion. Construction is relatively easy and construction costs can be reduced.
5). Since the ridges are shaped so as to be accurately fitted in the grooves, they can be fitted closely and have the effect that there is no sense of incongruity of the bonded floor boards.
6). The flooring is usually an elongated flat plate, but by connecting the ridges and grooves in the direction perpendicular to the longitudinal direction as well as the longitudinal direction, the connecting bamboo flooring can be connected in the direction perpendicular to the longitudinal direction. It is not necessary to use a long connecting bamboo flooring.

以下、本発明に係る連結竹床材を図面に示した実施例に基づいて説明する。図１は本発明に係る鉤型からなる連結竹床材の断面図であり、図２は本発明に係る溝付の連結竹床材の断面図である。また、図３は従来の連結部の断面図である。   Hereinafter, the connection bamboo flooring material concerning the present invention is explained based on the example shown in the drawing. FIG. 1 is a cross-sectional view of a connecting bamboo floor material having a saddle shape according to the present invention, and FIG. 2 is a cross-sectional view of a grooved connecting bamboo floor material according to the present invention. FIG. 3 is a cross-sectional view of a conventional connecting portion.

図１に表示される本件発明に係る鉤型からなる連結竹床材５０は、矩形長板の横幅方向の一方の端面に設けられた係合凸凹部６０と、他方の端面に設けられた前記凸凹部６０と嵌合する同形の嵌入凸凹部７０とから構成される。この実施例では、矩形長板は厚さ１５ｍｍの竹製の板材からなる。   The connecting bamboo floor material 50 composed of a saddle shape according to the present invention shown in FIG. 1 includes an engaging convex recess 60 provided on one end face in the lateral width direction of the rectangular long plate, and the above-described provided on the other end face. It is comprised from the same-shaped insertion convex-concave 70 fitted with the convex-concave 60. FIG. In this embodiment, the rectangular long plate is made of a bamboo plate having a thickness of 15 mm.

係合凸凹部６０は、矩形長板の長手方向と直交する横幅方向の一方の端面に設けられる係合部で、上段を長板の長手方向に延出して成形したその端面と並行に設けられた係合凸条６２と、凸条に隣接する裏面に削設された係合凹溝６４とから構成される。
係合凸凹部６０の形状は対応関係にある嵌入凸凹部７０と雌雄関係にあり、係合凸凹部と嵌入凸凹部とが相互に凹溝に凸条を嵌入させる鉤型に形成されている。 The engaging convex recess 60 is an engaging portion provided on one end face in the width direction orthogonal to the longitudinal direction of the rectangular long plate, and is provided in parallel with the end surface formed by extending the upper stage in the longitudinal direction of the long plate. The engaging ridge 62 and an engaging groove 64 cut on the back surface adjacent to the ridge.
The shape of the engaging convex recess 60 has a male-female relationship with the fitting convex concave portion 70 having a corresponding relationship, and the engaging convex concave portion and the fitting convex concave portion are formed in a bowl shape in which the convex strips are inserted into the concave grooves.

係合凸条６２は、端面の上段を延出して成形した先端に形成される凸条である。この実施例では延出幅を１５ｍｍに形成し、係合凸条の頂面の幅を１０ｍｍに形成するとともに、高さが長板の上面より８ｍｍに形成している。係合凸条６２の幅を広く形成することで、配送時等に加わる衝撃によっても凸条に破損を生じにくくしている。係合凸条６２は、他方の端面に設けられた嵌入凹溝７４と嵌合する構成である。   The engaging ridge 62 is a ridge formed at the tip formed by extending the upper stage of the end face. In this embodiment, the extending width is formed to 15 mm, the top surface of the engaging protrusion is formed to 10 mm, and the height is formed to 8 mm from the upper surface of the long plate. By forming the engaging ridge 62 wide, it is difficult for the ridge to be damaged by an impact applied during delivery or the like. The engaging ridge 62 is configured to fit into a fitting groove 74 provided on the other end face.

係合凹溝６４は、係合凸条６２と端面との間に形成される凹溝である。この実施例では、係合凹溝の幅を５ｍｍに形成し、深さを長板の下面より１０ｍｍに形成している。係合凹溝６４は、他方の端面に設けられた嵌入凸条７２と嵌合する構成であり雌雄の関係で同じサイズである。   The engagement groove 64 is a groove formed between the engagement protrusion 62 and the end surface. In this embodiment, the width of the engaging groove is 5 mm, and the depth is 10 mm from the lower surface of the long plate. The engaging groove 64 is configured to be fitted with the fitting protrusion 72 provided on the other end surface, and has the same size in relation to the sex.

嵌入凸凹部７０は、係合凸凹部６０の設けられている一方の端面とは反対側の他方の端面にその端面と並行に設けられる嵌入側の凸凹部であり、前記係合凸凹部６０を係合する対応する同形の嵌入凸条と嵌入凹溝とからなる形状の凸凹部である。嵌入凸凹部７０は、端面の下段を外方に延出して成形され、嵌入凸条７２と、嵌入凹溝７４とから構成される。
矩形長板からなる連結式の床材は、横幅方向の端面に設けられた係合凸凹部６０と嵌入凸凹部７０とを連結するが、長手方向に順次連結される隣接した長板の一方の横幅端面の係合凸凹部と隣接する長板の他方の端面の嵌入凸凹部とを係合させて順次連設する構成である。 The insertion convex recess 70 is a convex recess on the insertion side provided in parallel with the other end surface opposite to the one end surface where the engagement convex recess 60 is provided. It is a convex-concave part of the shape which consists of the corresponding same-shaped insertion protrusion and engagement groove | channel to engage. The insertion convex recess 70 is formed by extending the lower part of the end face outward, and includes an insertion convex line 72 and an insertion concave groove 74.
The connection type flooring made of rectangular long plates connects the engaging convex recesses 60 and the fitting convex recesses 70 provided on the end surface in the lateral width direction, but one of the adjacent long plates sequentially connected in the longitudinal direction. In this configuration, the engaging convex concave portion of the lateral end face is engaged with the fitting convex concave portion of the other end face of the adjacent long plate so as to be successively arranged.

嵌入凸条７２は、端面の下段を延出して成形した先端付近の表面に形成される凸条であり、この実施例では、全体の延出幅は１５ｍｍで、嵌入凸条の頂面の幅が５ｍｍで高さが長板の底面より１０ｍｍに形成されている。嵌入凸条の幅と高さは、係合凹溝６４の形状と対応するものである。   The insertion protrusion 72 is a protrusion formed on the surface near the tip formed by extending the lower end of the end face. In this embodiment, the entire extension width is 15 mm, and the width of the top face of the insertion protrusion Is 5 mm and the height is 10 mm from the bottom of the long plate. The width and height of the insertion protrusions correspond to the shape of the engagement groove 64.

嵌入凹溝７４は、嵌入凸条７２と端面との間に形成される凹部である。嵌入凹溝７４は、一方の端面に設けられた係合凸条６２と嵌合する構成である。係合凸凹部６０と嵌入凸凹部７０とを係合させて連設した際に係合凸条６２の下面と嵌入凹溝７４の間に隙間ができるように嵌入凹溝７４の深さは、係合凸条６２の高さよりも深く形成するとともに、嵌入凹溝７４の底面に固定部材を打設する複数の孔７８を穿設している。   The insertion recess groove 74 is a recess formed between the insertion protrusion 72 and the end surface. The fitting concave groove 74 is configured to be fitted with the engaging protrusion 62 provided on one end surface. The depth of the insertion groove 74 is such that a gap is formed between the lower surface of the engagement protrusion 62 and the insertion groove 74 when the engagement protrusion 60 and the insertion protrusion 70 are engaged with each other. A plurality of holes 78 are formed in the bottom surface of the fitting concave groove 74 so as to place a fixing member, while being formed deeper than the height of the engaging ridge 62.

この実施例で嵌入凹溝７４は、幅が１０ｍｍであり、高さが６ｍｍである。嵌入凹溝７４の高さは６ｍｍであるから、矩形長板の表面からの深さが９ｍｍに形成されている。係合凸条６２の高さは８ｍｍであるため係合凸凹部６０と嵌入凸凹部７０とを係合させて連設した際に係合凸条６２と嵌入凹溝７４の間に１ｍｍの隙間が生じる。   In this embodiment, the insertion concave groove 74 has a width of 10 mm and a height of 6 mm. Since the height of the insertion concave groove 74 is 6 mm, the depth from the surface of the rectangular long plate is 9 mm. Since the height of the engaging protrusion 62 is 8 mm, a gap of 1 mm is formed between the engaging protrusion 62 and the insertion groove 74 when the engagement protrusion 60 and the insertion protrusion 70 are engaged with each other. Occurs.

嵌入凹溝７４に穿設された孔７８は、釘・ネジ・ステープラのようなピン等の固定部材を嵌入し、隣接する床材と固定する為の孔である。また、下地材に強固に固定することも可能である。当該孔７８に固定部材は打設されるが、固定部材の頭部はこの係合凸条６２と嵌入凹溝７４の間の隙間に収まるので、係合凸凹部６０と嵌入凸凹部７０の嵌合に支障を生じさせない。たとえば、打ち込んだ固定部材の頭部が係合凸条６２の底面に当接して一方の端部を持ち上げるような事態は発生しない。また、フローリング形成後も、この隙間が存在するため嵌入凹溝７４の底面に突出した頭部に上部からの衝撃は直接伝わらない構造である。   A hole 78 formed in the insertion concave groove 74 is a hole for inserting a fixing member such as a pin such as a nail, a screw, or a stapler and fixing it to an adjacent floor material. It can also be firmly fixed to the base material. Although the fixing member is driven into the hole 78, the head of the fixing member fits in the gap between the engaging protrusion 62 and the insertion groove 74, so that the engagement protrusion 60 and the insertion protrusion 70 are fitted. Cause no trouble. For example, a situation where the head of the fixed member that has been driven abuts against the bottom surface of the engaging protrusion 62 and lifts one end portion does not occur. In addition, even after the flooring is formed, since this gap exists, the impact from the upper part is not directly transmitted to the head protruding from the bottom surface of the insertion groove 74.

本発明に係る鉤型からなる連結竹床材５０の両側である長手方向の側壁には、従来の連結構造１００である凸部１２０および凹部１３０が、それぞれ嵌合自在に形成されている形式であってもよい。従って、連設に際し、横幅方向を本件発明の構造で連設して固定するとともに長手方向を従来の連結構造で嵌合させることで、ずれ等の生じ難いフローリングを形成することができる。   A convex portion 120 and a concave portion 130 which are the conventional coupling structure 100 are formed on the side walls in the longitudinal direction, which are both sides of the connecting bamboo floor material 50 made of a saddle shape according to the present invention, so as to be freely fitted. There may be. Therefore, when connecting, the horizontal width direction is connected and fixed by the structure of the present invention, and the longitudinal direction is fitted by the conventional connection structure, thereby making it possible to form a flooring that is less likely to be displaced.

また、図２に表示される本件発明に係る溝付からなる別の連結竹床材１０は、凸条２０と、凹溝３０とから構成される。長板は上記と同様に竹材からなる。
凸条２０は、矩形長板の一方の長手方向の両側面の側壁に、その側壁に沿って並行に設けられた係合するための凸条であり、平板状の連結竹床材の対抗する側壁面の一方の側壁に設けられ、その形状は対応関係にある他方の側壁面の凹溝の形状と雌雄関係にあり、隣接する矩形長板床材の凸条と凹溝を嵌合する形状である。 Further, another connected bamboo floor material 10 having a groove according to the present invention displayed in FIG. 2 includes a ridge 20 and a groove 30. The long plate is made of bamboo as described above.
The ridges 20 are ridges for engaging with the side walls of one of the long sides of the rectangular long plate in parallel along the side walls, and are opposed to the flat connecting bamboo flooring. It is provided on one side wall of the side wall surface, and its shape is in a male-female relationship with the shape of the groove on the other side wall surface in a corresponding relationship, and is a shape that fits the ridge and groove on the adjacent rectangular long plate flooring. is there.

凸条２０は、凸部２２と、切欠部２４とから構成される。凸部２２は、凸条２０の端面に形成され、この実施例では凹溝に嵌合するように中段に設けられ凸部２２の突出幅は５ｍｍである。凸部２２は、後述の凹溝３０の凹部３２と嵌合する構成である。   The protruding line 20 includes a protruding part 22 and a notch part 24. The convex portion 22 is formed on the end face of the convex strip 20, and in this embodiment, the convex portion 22 is provided in the middle stage so as to be fitted into the concave groove, and the protruding width of the convex portion 22 is 5 mm. The convex portion 22 is configured to fit with a concave portion 32 of a concave groove 30 described later.

切欠部２４は、凸部２２が形成された端面の下段に形成される。この実施例では切欠部２４は、凸部２２の下側を１０ｍｍ切り欠いて形成し、凸部２２の突出幅５ｍｍと合せると奥行きは１５ｍｍとなり、後述の凹溝３０に形成された延出部３４と重なり合い、接合する。   The notch 24 is formed in the lower part of the end surface where the convex part 22 is formed. In this embodiment, the notch 24 is formed by notching the lower side of the protrusion 22 by 10 mm, and when combined with the protrusion width 5 mm of the protrusion 22, the depth becomes 15 mm, and an extension formed in a groove 30 described later. 34 and overlap.

凹溝３０は、凸条の設けられている側壁とは反対側の側壁にその側壁に沿って並行に設けられた凹溝であり、前記凸条と嵌合する同形の凹部である。凸条を嵌合するように上段の張出部３１と中段の凹部３２と下段の長く延出した延出部３４とからなり接合にあったては、隣接する竹床材の側壁の凸条と凹溝とを嵌合して連結させ、一定の広さの平板床材を構成する。   The concave groove 30 is a concave groove provided in parallel along the side wall on the side wall opposite to the side wall on which the convex line is provided, and is a concave part of the same shape that fits the convex line. In order to fit the ridges, the upper ridges 31, the middle dents 32, and the lower ridges 34 that extend long, the ridges on the side walls of the adjacent bamboo floor materials are joined. And a concave groove are fitted and connected to form a flat flooring material having a certain width.

中段の凹部３２の深さは、張出部３１の先端から５ｍｍである。凹部３２は、凸条２０の凸部２２と互いに嵌合自在に形成されている。   The depth of the middle recess 32 is 5 mm from the tip of the overhang 31. The concave portion 32 is formed so as to be able to fit with the convex portion 22 of the ridge 20.

延出部３４は、凹部３２が形成された端面の下段に上面部分よりも外方に延出して成形されている。延出部３４は、凸条２０の切欠部２４の形状と一致し、凸部２２と凹部３２を嵌合させることで接合する。延出部３４の延出幅は張出部３１の先端から１０ｍｍであり、凹部の深さ５ｍｍと合わせると延出部３４の幅は奥行きが１５ｍｍとなり、凸条２０の切欠部２４の奥行きと一致する。   The extending portion 34 is formed to extend outward from the upper surface portion at the lower stage of the end surface where the recessed portion 32 is formed. The extending part 34 matches the shape of the notch part 24 of the ridge 20 and is joined by fitting the convex part 22 and the concave part 32 together. The extension width of the extension portion 34 is 10 mm from the tip of the overhang portion 31, and when combined with the depth of the recess 5 mm, the extension portion 34 has a depth of 15 mm, and the depth of the notch 24 of the ridge 20 Match.

凹部３２には溝部３６が側壁に並行に削設されるとともに該溝部に固定部材を嵌入する複数の孔が穿設される構成である。
溝部３６は、凹溝３０の側壁と並行に延出部３４に形成され、所定の間隔に孔３８が穿けられている。溝部３６は、延出部３４の先端から５ｍｍの位置であり、幅は２ｍｍで、深さは１ｍｍである。溝部に設けられた孔３８は、固定部材（図示せず）を嵌入し、下地材に強固に固定するためのものである。 In the recess 32, a groove 36 is cut in parallel with the side wall, and a plurality of holes into which the fixing member is inserted are formed in the groove.
The groove portion 36 is formed in the extending portion 34 in parallel with the side wall of the recessed groove 30, and holes 38 are formed at predetermined intervals. The groove part 36 is located at a position 5 mm from the tip of the extension part 34, has a width of 2 mm, and a depth of 1 mm. The hole 38 provided in the groove is for fitting a fixing member (not shown) and firmly fixing to the base material.

本発明にかかる別の実施例である凸条と凹溝は、矩形長板の長手方向の側壁だけでなく、同時に長手方向と直交する横幅方向の側壁に設ける構成も可能であり、横幅方向の端面だけに設けることも可能である。   Another embodiment according to the present invention is not limited to the longitudinal side wall of the rectangular long plate, but can be configured to be provided on the lateral side wall perpendicular to the longitudinal direction at the same time. It is also possible to provide only on the end face.

これら本件発明のように固定部材を嵌入するための孔３８、７８を連結竹床材の構造に予め設けておけば、縦割れを生じやすい竹材の弱点を防ぎつつ釘等による固定が可能となる。また、孔３８、７８は、所定の間隔で穿けられているので、固定も所定間隔で行うことができ、施工による仕上がりが安定し、外観を損なうこともない。   If the holes 38 and 78 for inserting the fixing member are provided in the structure of the connecting bamboo floor material in advance as in the present invention, it is possible to fix with a nail or the like while preventing the weak point of the bamboo material that easily causes vertical cracks. . Further, since the holes 38 and 78 are formed at predetermined intervals, the holes 38 and 78 can be fixed at predetermined intervals, the finish by construction is stable, and the appearance is not impaired.

また、従来の根太上に固定する方法等では、釘により固定するため、頭部が表面に突出し、凸部と凹溝の嵌合が完全とならない場合も生じるが、孔３８は、溝部３６に形成されているので、固定部材の頭部が延出部３４の表面に突出することがなく、延出部３４と切欠部２４はしっかりと接合されることとなる。孔７８も嵌入凹溝７４に穿設されており、固定部材の頭部は係合凸条６２と嵌入凹溝７４の間の隙間に収まる。従って、固定部材が嵌合の邪魔になることはなく、正確に嵌合を行うことができる。更に、頭部が大きめの固定部材を使用することもできる。また、固定部材の頭部が表面に突出していると施工後も床を踏む衝撃が固定部材の頭部に伝わることとなり、この衝撃によっても縦割りを生じる可能性はあるが、本件発明によれば、このような現象も抑えることができる。   In addition, in the conventional method of fixing on the joist, etc., since the head is protruded from the surface because it is fixed by a nail, there is a case where the fitting between the convex part and the concave groove is not complete, but the hole 38 is formed in the groove part 36. Since it is formed, the head part of the fixing member does not protrude from the surface of the extension part 34, and the extension part 34 and the notch part 24 are firmly joined. The hole 78 is also formed in the insertion concave groove 74, and the head of the fixing member is accommodated in the gap between the engagement protrusion 62 and the insertion concave groove 74. Therefore, the fixing member does not interfere with the fitting, and the fitting can be performed accurately. Furthermore, a fixing member having a larger head can be used. In addition, if the head of the fixing member protrudes from the surface, the impact of stepping on the floor will be transmitted to the head of the fixing member even after construction, and this impact may also cause vertical splitting, but according to the present invention. Such a phenomenon can also be suppressed.

一方、下地材への固定も釘やネジ等の固定部材を使用することで、接着剤や両面テープ等よりも強固に行うことができる。従って、下地材に強固に固定された上に凸条２０と凹溝３０の嵌合または係合凸凹部６０と嵌入凸凹部７０の嵌合も正確に行われることとなり、本件発明に係る連結竹床材を用いた床は、ずれが生じ難いという特性を備える。更に、本件発明に係る鉤型からなる連結竹床材の構造によれば、長手方向よりも遥かに短い横幅方向の加工であるから、経済性と作業性および歩留に優れた構造でもある。   On the other hand, the fixing to the base material can be performed more firmly than the adhesive or the double-sided tape by using a fixing member such as a nail or a screw. Accordingly, the fitting of the ridges 20 and the grooves 30 or the fitting of the engaging protrusions 60 and the fitting protrusions 70 is performed accurately while being firmly fixed to the base material, and the connecting bamboo according to the present invention. A floor using a flooring material has a characteristic that it is difficult for displacement to occur. Furthermore, according to the structure of the connecting bamboo floor material composed of the saddle type according to the present invention, since it is processed in the width direction much shorter than the longitudinal direction, it is also a structure excellent in economy, workability and yield.

また、矩形長板の長手方向の両端面および横幅方向の両端面の四方向に連結構造を形成した連結竹床材とすることにより、隣接する連結竹床材を堅固に固定することができ、下地材へも強固に固定できる構造である。   In addition, by using a connected bamboo floor material in which the connection structure is formed in the four directions of both end surfaces in the longitudinal direction and the lateral width direction of the rectangular long plate, adjacent connected bamboo floor materials can be firmly fixed, The structure can be firmly fixed to the base material.
