Description

本発明は、天然木或いは再生木のデッキ材等からなる長尺板材の固定構造、及び長尺板材固定具に関するものである。   The present invention relates to a long plate material fixing structure made of natural wood or recycled wood deck material and the like, and a long plate material fixing tool.

公共施設や住宅の屋外スペースに設置される通常のウッドデッキは、支持枠上に横架されて固定された複数本の根太材、及び該根太材の長手方向に対して垂直に固定される複数枚の板状のデッキ材（以下、単に「床板」という）から構成され、前記ウッドデッキの高さを可変可能にする場合には、前記支持枠を支持して地面に立脚する支持脚もウッドデッキの構成に含まれる。   A normal wood deck installed in an outdoor space of a public facility or a house is composed of a plurality of joists fixed on a support frame and fixed in a vertical direction with respect to the longitudinal direction of the joists. In the case where the height of the wood deck is variable, the support legs that support the support frame and stand on the ground are also configured of the wood deck. include.

床板は、根太材上に並置され、各々所定の目地幅を有して固定具を介して根太材上に固定される。通常の床板は、両側面に長手方向に沿って溝が形成されており、前記固定具は前記溝に嵌合された状態で根太材に固定されることにより、床板が根太材に取り付けられる。前記固定具の根太材への固定方法は、固定具によるねじ留め方法が一般的であった。   The floorboards are juxtaposed on the joistwood, each having a predetermined joint width and fixed on the joistwood via a fixture. A normal floor board is formed with grooves on both side surfaces along the longitudinal direction, and the floor plate is attached to the joists by fixing the fixture to the joists while being fitted in the grooves. The fixing method of the fixing tool to the joist is generally a screwing method using a fixing tool.

しかし、従来の固定具を用いた方法で床板を取り付ける場合には、床板を根太材に端から一枚ずつ順番に並べ、一枚ずつ順番に固定させていく必要があった。従って、床板を取り外す際には、取付け時とは逆の手順で、端から一枚ずつ順番に取り外していかなければならなかった。特に、腐食した床板の交換、清掃等のメンテナンス、或いはデッキ下への落下物を拾う等、特定の床板のみ或いは特定の一部分を取り外したい場合でも、順番に取り外す必要があり、大変な手間と労力を要していた。また、床板の取付け、取外し作業が敬遠されるために、デッキ下の空間を有効に活用できなかった。   However, when the floor board is attached by a method using a conventional fixing tool, it is necessary to arrange the floor board one by one on the joist from the end and fix them one by one. Therefore, when removing the floorboards, it was necessary to remove them one by one from the end in the reverse order of attachment. In particular, even if you want to remove only a specific floorboard or a specific part, such as replacement of corroded floorboards, maintenance such as cleaning, or picking up objects falling under the deck, it is necessary to remove them in order, and it takes a lot of labor and labor Needed. In addition, the space under the deck could not be used effectively because the installation and removal of floorboards was avoided.

上記問題点を解決するために、必要な床板のみを取り外すことが可能な床構造が提案されている。例えば、特許文献１では、図１５に示すように、床板１１０の目地１１１内に配置された取付金具Ｍ1 が開示されている。前記取付金具Ｍ1 は、床板１１０の目地幅Ｗ10に収まる本体部１０１と、該本体部１０１上面に配された略長方形の係止片１０２とから成り、該係止片１０２は、中心にビス１２１を貫通させた状態で、水平面内で回動可能に前記本体部１０１と固定されている。前記床板１１０の固定の際は、目地幅Ｗ10に対応させて根太１３０上に固定された各取付金具Ｍ1 の両脇に床板１１０を載置し、前記床板１１０側面の溝１１２内に前記係止片１０２の長手部分を前記ビス１２１により回動させて挿入し、前記長手部分の先端部に形成された突起１０３を前記溝１１２の下面を押圧させることで、前記床板１１０を固定している。しかし、前記取付金具Ｍ1 の幅、即ち本体部１０１の幅は、床板１１０の目地幅Ｗ10に相当するため、細い目地幅Ｗ10の間で、床板１１０の固定及び解除の細かい作業をするのは困難であると同時に、目地幅Ｗ10を細くするのに限界がある。即ち、床板１１０の目地幅Ｗ10を、例えば、目地幅としてよく選択される３ないし５ｍｍの大きさに設定することはほぼ不可能である。 In order to solve the above problems, a floor structure in which only a necessary floor board can be removed has been proposed. For example, in Patent Document 1, as shown in FIG. 15, mounting bracket M 1 is disclosed which is arranged in the joint 111 of the floor plate 110. The mounting bracket M 1 includes a main body portion 101 that fits within the joint width W 10 of the floor plate 110, and a substantially rectangular locking piece 102 disposed on the upper surface of the main body portion 101. The locking piece 102 is centered. In a state where the screw 121 is penetrated, the screw body 121 is fixed to the main body 101 so as to be rotatable in a horizontal plane. When the floor plate 110 is fixed, the floor plate 110 is placed on both sides of each mounting bracket M 1 fixed on the joist 130 corresponding to the joint width W 10 , and the floor plate 110 is placed in the groove 112 on the side surface of the floor plate 110. The locking plate 102 is inserted by rotating the longitudinal portion of the locking piece 102 with the screw 121 and pressing the lower surface of the groove 112 with the projection 103 formed at the tip of the longitudinal portion. Yes. However, the mounting bracket M 1 width, i.e. the width of the body 101, in order to correspond to the joint width W 10 of the floor plate 110, between the narrow joint width W 10, the fine work of fixing and release of the floorboard 110 It is difficult to reduce the joint width W 10 at the same time. That is, it is almost impossible to set the joint width W 10 of the floor board 110 to a size of 3 to 5 mm, which is often selected as the joint width, for example.

また、特許文献２では、図１６に示すように、床板２１０側面の溝２１２に嵌合した状態で、根太２３０の受け部２３１を挟み込んで前記床板２１０を前記根太２３０に固定する床板固定具Ｍ2 が開示されている。前記床板固定具Ｍ2 は、前記根太２３０を幅方向から挟み込む部分２０１と、前記床板２１０側面の溝２１２に嵌合する部分２０２を有しており、前記床板２１０を根太２３０上に固定する際は、前記床板２１０側面の溝２１２に前記床板固定具Ｍ2 を嵌合させた状態で、前記床板固定具Ｍ2 を金槌等で叩きながら前記幅方向から根太２３０に挟み込ませていく。前記床板２１０を取り外す際は、上記固定方法と逆の手順をたどる。しかし、前記床板固定具Ｍ2 によって根太２３０から床板２１０を着脱する際には、細い目地幅Ｗ20の目地２１１内に工具を差し入れて、前記工具を介して前記床板固定具Ｍ2 を叩き打ち、前記床板固定具Ｍ2 を根太２３０に挟み込ませたり、根太２３０から取り外したりしなければならない。このため、細形状の工具を必要とし、狭い目地２１１内での作業が面倒である。また、目地幅Ｗ20を比較的大きく設定する場合には、前記床板固定具Ｍ2 を根太２３０に挟み込む位置を変えるだけで目地幅Ｗ20を自由に調節できるが、自由に調節可能であるために、目地幅Ｗ20を全て一定として床板２１０を敷設するには作業者の技術や経験を要する。また、前記床板固定具Ｍ2 は前記目地２１１内に床板固定具Ｍ2 が収まる構造であり、目地２１１内で前記床板固定具Ｍ2 を根太２３０から着脱する作業をする必要があるため、目地幅Ｗ20を細く設定する際にはやはり限界がある。
特開２００３−２２７２２４号公報 特開２００５−１０５８０２号公報 In Patent Document 2, as shown in FIG. 16, a floor plate fixture M that fixes the floor plate 210 to the joist 230 by sandwiching the receiving portion 231 of the joist 230 in a state of being fitted in the groove 212 on the side surface of the floor plate 210. 2 is disclosed. The floor plate fixture M 2 has a portion 201 that sandwiches the joist 230 from the width direction and a portion 202 that fits into a groove 212 on the side surface of the floor plate 210, and when the floor plate 210 is fixed on the joist 230. , the state in which the mated floorboards fixture M 2 in the groove 212 of the floor plate 210 side, will not sandwiched joists 230 the floor plate fixture M 2 from the width direction while hitting a hammer or the like. When removing the floor board 210, the reverse procedure of the fixing method is followed. However, when the floor plate 210 is detached from the joist 230 by the floor plate fixture M 2 , a tool is inserted into the joint 211 having a narrow joint width W 20 and the floor plate fixture M 2 is struck through the tool. The floor plate fixture M 2 must be sandwiched between the joists 230 and removed from the joists 230. For this reason, a thin tool is required and the work in the narrow joint 211 is troublesome. When the joint width W 20 is set to be relatively large, the joint width W 20 can be freely adjusted by changing the position where the floor plate fixture M 2 is sandwiched between the joists 230. However, the joint width W 20 can be freely adjusted. In addition, in order to lay the floor plate 210 with the joint width W 20 all constant, it is necessary to have the skill and experience of the operator. Further, since the floor plate fixture M 2 is a structure in which the floor plate fixture M 2 falls within the joint 211, it is necessary to work for attaching and detaching the floor plate fixture M 2 from the joists 230 in the joint 211, joint There is a limit in setting the width W 20 to be narrow.

本発明は、床面、壁面、又は天井面等の建物の敷設面に多数の長尺板材が敷設された状態で、任意の長尺板材を取り外し可能にすると共に、前記敷設に際しては、敷設面の任意の箇所から開始可能にすることである。   The present invention makes it possible to remove any long plate material in a state in which a large number of long plate materials are laid on the laying surface of a building such as a floor surface, a wall surface, or a ceiling surface. It is possible to start from any point.

上記の課題を解決するための請求項１の発明は、長尺板材の端面に長手方向に沿って係止溝が形成されていて、固定材に板材幅に対応した幅で複数の長尺板材固定具が固定されて、長尺板材固定具の係止部が長尺板材の係止溝に係止されて、長尺板材固定具を介して長尺板材を固定材に固定する構造であって、前記長尺板材固定具は、弾性変形可能なバネ材で成形されて、取付具を介して前記固定材に固定される固定部と、当該固定部の幅方向の両端部から鈍角状に起立して対向形成された一対の係止部とから成って、前記各係止部の先端部には、長尺板材の着脱時に当該長尺板材の端面に摺接して前記係止部を弾性変形させる摺接部が外方に突出してそれぞれ形成され、固定状態の特定の長尺板材を幅方向にスライドさせて、長尺板材の幅方向の一方の長尺板材固定具の前記係止部を弾性変形させて、長尺板材の幅方向に沿って隣接する長尺板材固定具の開口幅を広げることにより、当該長尺板材の幅方向の他方の端部を持ち上げて、その傾斜姿勢のままで長尺板材を傾斜方向にスライドさせる操作、及びこの逆操作を行なうことにより、敷設された長尺板材群のうち特定の長尺板材の脱着を可能にしたことを特徴としている。   In the invention of claim 1 for solving the above-mentioned problem, a locking groove is formed along the longitudinal direction on the end face of the long plate material, and the fixed material has a plurality of long plate materials having a width corresponding to the plate material width. The fixing device is fixed, the locking portion of the long plate material fixing device is locked in the locking groove of the long plate material, and the long plate material is fixed to the fixing material via the long plate material fixing device. The long plate material fixture is formed of an elastically deformable spring material and fixed to the fixing material via a fixture, and an obtuse angle from both ends in the width direction of the fixed portion. It consists of a pair of standing and opposed locking portions, and the locking portions are elastically brought into sliding contact with the end surfaces of the long plate members at the distal end portions of the respective locking portions when the long plate materials are attached and detached. Sliding contact parts to be deformed are formed to protrude outward, and a specific long plate material in a fixed state is slid in the width direction to change the width of the long plate material. The width of the long plate member is increased by elastically deforming the locking portion of the one long plate member in the direction and widening the opening width of the adjacent long plate member along the width direction of the long plate member. By lifting the other end of the direction and sliding the long plate material in the inclined direction while maintaining its inclined posture, and by performing the reverse operation, a specific long plate material among the long plate material group laid It is characterized by the fact that it is possible to detach and attach.

請求項１の発明によれば、長尺板材が床板であり、固定材が根太材である場合には、根太材に床板を敷設するには、根太材に床板幅に対応したピッチで床板固定具を固定しておき、床板を自身の幅方向に沿って傾斜させ、傾斜の低い側の床板端部の係止溝に床板固定具の係止部を係止させてから、床板を前記傾斜方向に沿って前記係止部を押圧させていくと、床板固定具の係止部は起立角度が小さくなるように弾性変形されて、相隣接する床板固定具の間隔が広くなる。この状態で、傾斜姿勢の高い側の床板端部を押し下げると、当該端部に対応する位置に配置された床板固定具の一方の係止部の上端の摺接部に床板の端面が摺接することにより、床板固定具の起立部は起立角度が小さくなる方向に弾性変形されて、相隣接する床板固定具の間に床板が配置される。この状態では、床板の幅方向の両端の各係止溝に、隣接する各床板固定具の摺接部が収容された状態で、当該各係止溝に係止部が係止される。   According to the invention of claim 1, when the long board is a floor board and the fixing material is a joist, in order to lay the floor board on the joist, the floor board is fixed at a pitch corresponding to the floor board width. Fix the fixture, tilt the floorboard along its own width direction, lock the locking portion of the floorboard fixture in the locking groove on the lower end of the floorboard, and then tilt the floorboard When the locking part is pressed along the direction, the locking part of the floor board fixture is elastically deformed so that the standing angle becomes small, and the interval between the floor board fixtures adjacent to each other is widened. In this state, when the floor plate end portion on the higher inclined posture side is pushed down, the end surface of the floor plate comes into sliding contact with the sliding contact portion at the upper end of one locking portion of the floor plate fixing device arranged at a position corresponding to the end portion. Thereby, the standing part of the floor board fixture is elastically deformed in the direction in which the standing angle becomes smaller, and the floor board is arranged between the adjacent floor board fixtures. In this state, the locking portions are locked to the locking grooves in a state where the sliding contact portions of the adjacent floor plate fixing tools are accommodated in the locking grooves at both ends in the width direction of the floor plate.

上記のようにして、床板固定具を介して根太材に床板が敷設された状態では、床板の係止溝に床板固定具の係止部が係止されることにより、床板の浮き上がりが防止される。   As described above, in the state in which the floor board is laid on the joists through the floor board fixing tool, the locking part of the floor board fixing tool is locked in the locking groove of the floor board, thereby preventing the floor board from being lifted. The

また、上記以外の床板の固定方法としては、床板をほぼ水平にした状態で、床板固定具の弾性力に抗して直上から押圧し、相隣接する床板固定具の間に床板を無造作に落とし込むことによって行なうことも可能である。   In addition to the above, the floor board may be fixed in a state where the floor board is almost horizontal and pressed from directly above against the elastic force of the floor board fixture to drop the floor board between adjacent floor board fixtures. It is also possible to do this.

一方、敷設された床板群のうち特定の床板を取り外すには、当該床板を略目地分だけ幅方向にスライドさせて、床板の幅方向の一方の床板固定具の前記係止部を弾性変形させると、床板の幅方向に沿って隣接する床板固定具の開口幅が広くなる。この結果、当該床板の幅方向の他方の端部においては、係止溝に対する床板固定具の係止部の係止が緩やかになるか、或いは係止が解除された状態となる。このため、当該床板の幅方向の他方の端部を持ち上げると、当該端部の係止が緩やかな場合には、当該部分に配置された床板固定具の係止部が、当該床板の係止溝と床板固定具の係止部との係止が解除される方向に弾性変形されて、当該床板の他方の端部は、隣接する床板の上面よりも上方まで持ち上げ可能となり、この傾斜姿勢において当該床板を傾斜方向に引き上げると、当該床板に隣接する両床板が固定されたままで、当該床板のみが外される。取り外した特定の床板を元の位置に戻して固定するには、上記各操作を順次逆の順序で行えばよい。   On the other hand, in order to remove a specific floor board from the laid floor board group, the floor board is slid in the width direction substantially by the joint area, and the locking portion of one floor board fixture in the width direction of the floor board is elastically deformed. And the opening width of the floor board fixing tool adjacent along the width direction of a floor board becomes wide. As a result, at the other end portion in the width direction of the floor plate, the lock of the lock portion of the floor plate fixture with respect to the lock groove is loosened or the lock is released. For this reason, when the other end portion in the width direction of the floor board is lifted, when the end portion is loosely locked, the locking portion of the floor plate fixture arranged in the portion is locked to the floor plate. It is elastically deformed in the direction in which the locking between the groove and the locking part of the floor board fixture is released, and the other end of the floor board can be lifted above the upper surface of the adjacent floor board. When the floor board is pulled up in the inclined direction, only the floor board is removed while both floor boards adjacent to the floor board are fixed. In order to return the fixed floor board to the original position and fix it, the above operations may be performed in the reverse order.

請求項２の発明は、請求項１に記載の長尺板材の固定構造において、前記長尺板材固定具の係止部は、弾性変形された状態で長尺板材の係止溝に係止されることを特徴としている。   According to a second aspect of the present invention, in the long plate member fixing structure according to the first aspect, the locking portion of the long plate member fixing member is locked in the locking groove of the long plate member in a state of being elastically deformed. It is characterized by that.

請求項２の発明によれば、床板の係止溝に対して床板固定具の係止部が弾性変形して係止された状態においても、床板固定具の固定部に対する係止部の起立角度は鈍角を保持しているため、床板の係止溝に対する床板固定具の係止部の弾接力は、斜下方に作用する。よって、敷設された床板は、前記弾接力の下方分力により下方に押し付けられるので、敷設状態が安定化する。なお、敷設された床板の幅方向の位置は、両側の各床板固定具の前記弾接力の水平分力が均衡することにより定められる。   According to the invention of claim 2, even when the locking portion of the floor board fixture is elastically deformed and locked with respect to the locking groove of the floor board, the upright angle of the locking portion with respect to the fixing portion of the floor board fixture Holds an obtuse angle, the elastic contact force of the locking portion of the floor plate fixture with respect to the locking groove of the floor plate acts obliquely downward. Therefore, since the laid floor board is pressed downward by the downward component force of the elastic contact force, the laid state is stabilized. The position in the width direction of the laid floorboard is determined by balancing the horizontal component of the elastic contact force of the floorboard fixtures on both sides.

請求項３の発明は、請求項１又は２に記載の長尺板材の固定構造において、前記長尺板材固定具の摺接部は、開口が対向するように外方にわん曲された断面形状を有することを特徴としている。   The invention according to claim 3 is the fixing structure of the long plate material according to claim 1 or 2, wherein the sliding contact portion of the long plate material fixture is bent in a cross section outward so that the openings face each other. It is characterized by having.

請求項３の発明によれば、床板固定具の摺接部は、外方にわん曲して形成されているので、特定の床板のみを脱着する場合において、床板の端面が係止部の外周面に引っ掛かることなく円滑に摺接して、床板固定具の係止部が弾性変形されるために、上記した特定の床板の脱着が容易となる。   According to the invention of claim 3, since the sliding contact portion of the floor plate fixture is bent outwardly, when only a specific floor plate is attached or detached, the end surface of the floor plate is the outer periphery of the locking portion. Since the engaging portion of the floor board fixture is elastically deformed without being caught on the surface and elastically deformed, the above-described specific floor board can be easily attached and detached.

請求項４の発明は、請求項２又は３に記載の長尺板材の固定構造において、前記長尺板材固定具の対向形成された各係止部には、各係止部の弾性変形を維持するための弾性変形維持部材が嵌着されていることを特徴としている。   According to a fourth aspect of the present invention, in the fixing structure of the long plate material according to the second or third aspect, the elastic deformation of each locking portion is maintained in each locking portion formed opposite to the long plate material fixture. It is characterized in that an elastic deformation maintaining member is attached.

請求項４の発明によれば、床板固定具の各係止部の弾性変形状態が長期に亘って維持されるため、床板の係止溝に対する床板固定具の係止部の弾接状態がそのまま維持されて、長期間の使用によっても床板が長手方向にずれなくなる。   According to the invention of claim 4, since the elastic deformation state of each locking portion of the floor board fixture is maintained over a long period of time, the elastic contact state of the locking portion of the floor board fixture with respect to the locking groove of the floor board remains as it is. The floor board is not displaced in the longitudinal direction even after long-term use.

請求項５の発明は、端面に長手方向に沿って係止溝が形成された長尺板材を固定材に固定するように使用される長尺板材固定具であって、弾性変形可能なバネ材で成形されて、取付具を介して前記固定材に固定される固定部と、当該固定部の幅方向の両端部から鈍角状に起立して対向形成された一対の係止部とから成って、前記各係止部の先端部には、長尺板材の着脱時に当該長尺板材の端面に摺接して前記係止部を弾性変形させる摺接部が外方に突出してそれぞれ形成されていることを特徴としている。   The invention of claim 5 is a long plate material fixture used to fix a long plate material having a locking groove formed in the end surface along the longitudinal direction to the fixed material, and is an elastically deformable spring material A fixed portion that is molded to be fixed to the fixing material via a fixture, and a pair of locking portions that are formed in an obtuse angle from both ends in the width direction of the fixed portion so as to face each other. In addition, a sliding contact portion that slides on the end surface of the long plate material and elastically deforms the locking portion when the long plate material is attached or detached is formed on the distal end portion of each locking portion so as to protrude outward. It is characterized by that.

請求項５の発明は、請求項１の発明を「長尺板材固定具」の面から把握したものであって、請求項１の発明と実質的には同一である。   The invention of claim 5 is obtained by grasping the invention of claim 1 from the aspect of the “long plate member fixing tool”, and is substantially the same as the invention of claim 1.

請求項６の発明は、端面に長手方向に沿って係止溝が形成された長尺板材を固定材に固定するように使用される長尺板材固定具であって、弾性変形可能なバネ材で成形されて、取付具を介して前記固定材に固定される固定部と、当該固定部の幅方向の両端部であって、しかも長手方向に沿ってずれた位置に鋭角状に起立された一対の係止部とから成って、前記各係止部の先端部には、長尺板材の着脱時に当該長尺板材の端面に摺接して前記係止部を弾性変形させる摺接部が正面視において外方に突出してそれぞれ形成されていることを特徴としている。   The invention of claim 6 is a long plate material fixture used to fix a long plate material having a locking groove formed in the end surface along the longitudinal direction to the fixed material, and is an elastically deformable spring material And fixed portions fixed to the fixing material via a fixture, and both end portions in the width direction of the fixing portions, and are raised at acute angles at positions shifted along the longitudinal direction.

When fixing the long plate member fixing tool to the fixing material, first, the insertion fitting is inserted into the sleeve hole in accordance with the direction in which the longitudinal direction of the insertion rotating portion coincides with the longitudinal direction of the horizontally long sleeve hole. Next, after inserting an insertion rotation part into the back side of a fixing material, the said elongate board | plate material fixing tool is rotated 90 degrees. As a result, the long plate member fixing tool rotates 90 ° about the insertion shaft foot, so that the longitudinal direction of the insertion rotating part is orthogonal to the longitudinal direction of the sleeve hole, and the insertion rotating part is locked to the fixing material. Thus, it does not come out of the sleeve hole. Accordingly, the long plate material fixture is fixed to the fixture via the insertion fixture. With the above procedure, a plurality of long plate fixtures may be fixed to the sleeve holes at intervals corresponding to the plate width. In addition, when removing the long plate material fixing tool from the fixing material, after removing the long plate material from the long plate material fixing device, the long plate material fixing device is rotated by 90 ° again, thereby inserting the back side of the fixing material. Since the longitudinal direction of the rotating part again coincides with the longitudinal direction of the sleeve hole, the insertion rotating part may be extracted from the sleeve hole.

Moreover, the fixture is not lost. Moreover, by using together the said long board | plate material fixing tool and the fixing material in which the sleeve hole was formed, it becomes detachable from a fixing material only by rotating the said long board | plate material fixing tool. Accordingly, even when changing to a long plate material having a different plate material width, the fixing position of the long plate material fixing tool on the fixing material can be easily changed, and the work can be performed efficiently. If the long plate material fixture is applied to the inner wall, the partition wall, or the ceiling, the wall plate and the ceiling plate can be easily changed, so that the room can be easily redesigned and reformed.

請求項１１の発明は、幅方向の端面に長手方向に沿って請求項１ないし１０に記載の長尺板材固定具を係止可能な係止溝が形成された長尺板材であって、断面長方形状の板材本体と、当該板材本体の長手方向の両端部の下面に一体に取り付けられて前記係止溝を形成するための係止溝形成具とから成ることを特徴としている。   The invention of claim 11 is a long plate material in which a locking groove capable of locking the long plate material fixing device according to any one of claims 1 to 10 is formed along the longitudinal direction on an end surface in the width direction, It is characterized by comprising a rectangular plate body and a locking groove forming tool which is integrally attached to the lower surfaces of both end portions in the longitudinal direction of the plate body to form the locking groove.

請求項１１の発明に係る長尺板材は、薄板状の板材本体と、当該板材本体の長手方向の両端部における下面に一体に取り付けられた係止溝形成具とから成り、板材本体の「台」に当該係止溝形成具の「歯」がついた下駄状の構造になっている。当該係止溝形成具は、軽金属（アルミニウム等）や樹脂の押出成形等で成形されたもので、幅方向の両端部には、長尺板材固定具の係止部を係止可能な係止溝が形成されている。長尺板材が上記の構造をしていることによって、長尺板材全体が再生木、又はむくの天然木である場合に比べて、以下の効果が奏される。まず、板材本体のみを再生木や天然木にすれば良いため、再生木や天然木に係止溝等の加工をする必要がないので、加工し易い。また、当該長尺板材は押出し成形品であるので加工精度も得られ、かつ経済的であり、長尺板材の重量も軽減されるので作業し易い。更に、板材本体は断面長方形の板材であれば良いので木製の板材に限られない。板材本体として、ガラスやアクリル板、金属パネル等多彩な材質の板材を利用することが可能となるので長尺板材の選択の幅が広がり、軽量な板材を使用すれば、床板のみならず、壁板や天井板にも適用可能となる。   The long plate material according to the invention of claim 11 is composed of a thin plate material body, and a locking groove forming tool integrally attached to the lower surface at both longitudinal ends of the plate material body. ”Is a clog-like structure with“ teeth ”of the locking groove forming tool. The locking groove forming tool is formed by light metal (aluminum or the like) or resin extrusion molding, etc., and can be locked at both ends in the width direction with the locking portion of the long plate material fixing tool. Grooves are formed. Due to the long plate material having the above-described structure, the following effects can be achieved as compared with the case where the entire long plate material is a recycled wood or a bare natural wood. First, since it is sufficient that only the plate material main body is made of recycled wood or natural wood, it is not necessary to process the retaining groove or the like on the recycled wood or natural wood, so that it is easy to work. Further, since the long plate material is an extrusion-molded product, processing accuracy can be obtained and it is economical, and the weight of the long plate material is reduced, so that it is easy to work. Further, the plate body is not limited to a wooden plate, as long as the plate body has a rectangular cross section. As the plate body, it is possible to use plate materials of various materials such as glass, acrylic plates, metal panels, etc., so the range of choice of long plate materials is widened, and if light plate materials are used, not only floor plates but also walls It can also be applied to boards and ceiling boards.

請求項１２の発明は、請求項１１に記載の発明において、前記係止溝形成具は、板材本体の幅方向の端部に嵌着される断面コ字形の嵌着部を備え、当該嵌着部により板材本体に一体に取り付けられることを特徴としている。   According to a twelfth aspect of the present invention, in the invention according to the eleventh aspect, the locking groove forming tool includes a fitting portion having a U-shaped cross section to be fitted to an end portion in the width direction of the plate body. It is characterized by being integrally attached to the plate material main body by the portion.

請求項１２の発明は、請求項１１に記載の発明に対して、前記板材本体の幅方向の端部に断面コ字形の嵌着部を備えている点が異なるのみで、他の構成は同一であり、請求項１１の発明と同等の作用効果が奏される。更に、前記嵌着部により、板材本体は幅方向の端部で嵌着されて係止溝形成具と一体化されるので、以下のような効果も奏される。即ち、板材本体が木製の薄板の場合には、長尺板材に係止溝形成具をビス類で取り付けることは可能であるが、板材本体がガラス板等の場合には、ビス類で取り付けるのは困難であり、ビス孔の孔開け作業等の余計な作業工程を要する。しかし、前記係止溝形成具は前記嵌着部を有することにより、ビス類等で固定することが困難な材質の板材でも板材本体として使用することが可能となって、使用できる板材の選択の幅がより一層広がる。また、工具等を用いてビス類を抜き取ることなく板材本体を係止溝形成具から外すことも容易に行える。即ち、前記嵌着部により容易に板材本体を係止溝形成具から着脱可能である。従って、嵌着部と一体化した係止溝形成具及び板材本体から成る長尺板材は、軽量でかつ多様な板材に容易に交換可能であるため、内壁や間仕切壁の壁板や、天井板として最適である。   The invention of claim 12 differs from the invention of claim 11 only in that the plate body has a U-shaped fitting portion at the end in the width direction, and the other configurations are the same. Thus, the same effect as that attained by the 11th aspect can be attained. Furthermore, the plate member main body is fitted at the end in the width direction by the fitting portion and integrated with the locking groove forming tool, and the following effects are also exhibited. In other words, when the plate body is a thin wooden plate, it is possible to attach the locking groove forming tool to the long plate with screws, but when the plate body is a glass plate, it is attached with screws. Is difficult and requires an extra work step such as drilling a screw hole. However, since the locking groove forming tool has the fitting portion, it is possible to use a plate material made of a material difficult to fix with screws or the like as the plate material body. The width further expands. Further, it is possible to easily remove the plate material body from the locking groove forming tool without removing the screws using a tool or the like. That is, the plate body can be easily detached from the locking groove forming tool by the fitting portion. Therefore, the long plate material composed of the locking groove forming tool and the plate material main body integrated with the fitting portion is lightweight and can be easily replaced with various plate materials. As best.

本発明によれば、床面、壁面、又は天井面等の敷設面に多数の長尺板材が敷設された状態において、任意の長尺板材を取り外して、当該長尺板材を再び取り付けることが可能となると共に、敷設面の任意の箇所から敷設を開始することが可能となる。   According to the present invention, in the state where a large number of long plate materials are laid on a floor surface, a wall surface, or a ceiling surface, it is possible to remove any long plate material and reattach the long plate material. In addition, it is possible to start laying from an arbitrary location on the laying surface.

以下、最良の実施形態を挙げて本発明について更に詳細に説明する。建物の敷設面には、床面、壁面、天井面が挙げられる。ここでは、前記敷設面が床面、長尺板材が床板、及び固定材が根太材である場合について説明する。最初に、図１ないし図４を用いて、床板固定具の構成について説明する。次に、根太材上に固定された床板固定具と床板との関係を構成面から説明する。図１は、根太材Ｊ上に固定された床板固定具Ａ1 を介して敷設された床板Ｂ1 群の平面図である。図２は、床板固定具Ａ1 の全体斜視図である。図３は、床板固定具Ａ1 を介して床板Ｂ1 が根太材Ｊ上に固定された状態を示す正面断面図である。図４は、床板Ｂ1 が敷設されていない状態における根太材Ｊ上に固定された床板固定具Ａ1 を示す斜視図である。 Hereinafter, the present invention will be described in more detail with reference to the best mode. The laying surface of the building includes a floor surface, a wall surface, and a ceiling surface. Here, the case where the laying surface is a floor surface, the long plate material is a floor plate, and the fixing material is a joist is described. Initially, the structure of a floor-plate fixing tool is demonstrated using FIG. 1 thru | or FIG. Next, the relationship between the floorboard fixture fixed on the joist and the floorboard will be described from the structural aspect. FIG. 1 is a plan view of a floor board B 1 group laid through a floor board fixture A 1 fixed on the joist J. FIG. Figure 2 is an overall perspective view of a floor panel fastener A 1. FIG. 3 is a front cross-sectional view showing a state in which the floor board B 1 is fixed on the joist J through the floor board fixing tool A 1 . FIG. 4 is a perspective view showing the floor board fixture A 1 fixed on the joist J in a state where the floor board B 1 is not laid.

まず、床板固定具Ａ1 の構成について説明する。図２に示されるように、床板固定具Ａ1 は、弾性変形可能なばね鋼で成形され、根太材Ｊ上にビス類６１で固定される固定部１０と、当該固定部１０の幅方向の両端から起立して左右対称に対向形成された一対の係止部２０からなる。当該係止部２０の各先端部には、外方に突出した摺接部２１が形成されている。固定部１０には、固定部１０の長手方向に沿って一箇所或いは複数箇所にビス孔１１が形成されている。当該ビス孔１１は、床板固定具Ａ1 を根太材Ｊ上にビス固定するためのものである。一対の係止部２０は、それぞれ前記固定部１０と鈍角の起立角度θ0 を有して起立し、対向形成されている。前記係止部２０の各先端部に形成された摺接部２１は、前記係止部２０の起立方向よりも外方に突出した部分を有する。前記摺接部２１が外方に突出していることによって、床板Ｂ1 の着脱時において、前記摺接部２１を床板Ｂ1 の下端面１ｂに摺接させ易くなる。また、前記摺接部２１が前記下端面１ｂに摺接することにより、前記摺接部２１を先端部に有する係止部２０は、起立角度θが非変形状態の起立角度θ0 よりも小さくなるように弾性変形する。上記の摺接部２１の効果が十分に発揮されて、前記摺接部２１の外周面に床板Ｂ1 の下端面１ｂが引っ掛かることなく円滑に摺接するためには、摺接部２１の最適形状は、開口８が対向するように外方にわん曲された断面円弧状、又は近似円弧状であることが望ましい。 First, the configuration of the floor plate fixture A 1. As shown in FIG. 2, the floor plate fixture A 1 is formed of elastically deformable spring steel, fixed to the joist member J with screws 61, and the width direction of the fixed portion 10. It consists of a pair of latching | locking part 20 which stood up from both ends and was formed oppositely symmetrically. A sliding contact portion 21 protruding outward is formed at each distal end portion of the locking portion 20. Screw holes 11 are formed in the fixing portion 10 at one or a plurality of locations along the longitudinal direction of the fixing portion 10. The screw hole 11 is for fixing the floor plate fixture A 1 onto the joist J. The pair of locking portions 20 stand up with an obtuse rising angle θ 0 with respect to the fixed portion 10 and are formed to face each other. The slidable contact portion 21 formed at each distal end portion of the locking portion 20 has a portion protruding outward from the standing direction of the locking portion 20. Since the sliding contact portion 21 protrudes outward, the sliding contact portion 21 is easily brought into sliding contact with the lower end surface 1b of the floor plate B 1 when the floor plate B 1 is attached or detached. Further, when the sliding contact portion 21 is in sliding contact with the lower end surface 1b, the locking portion 20 having the sliding contact portion 21 at the distal end has an upright angle θ smaller than an upright angle θ 0 in a non-deformed state. It is elastically deformed. In order that the effect of the sliding contact portion 21 is sufficiently exhibited and the lower end surface 1b of the floor plate B 1 is smoothly slidably contacted with the outer peripheral surface of the sliding contact portion 21, the optimum shape of the sliding contact portion 21 is obtained. Is preferably in the shape of an arc of cross section that is bent outward so that the openings 8 face each other, or an approximate arc shape.

根太材Ｊ上に固定された床板固定具Ａ1 と床板Ｂ1 との関係について説明する。以下、長尺板材の長手方向を方向Ｔ、幅方向を方向Ｕ、及び固定材の長手方向を方向Ｓとし、ここでは、床板Ｂ1 の長手方向、幅方向をそれぞれ方向Ｔ、方向Ｕ、及び根太材Ｊの長手方向を方向Ｓと単にいうことがある。まず、図１及び図４に示されるように、床板固定具Ａ1 は、当該床板固定具Ａ1 の固定部１０の幅方向が根太材Ｊの長手方向Ｓと平行になるように根太材Ｊ上に配置された状態で、方向Ｓに沿ってビス類６１で固定され、根太材Ｊ上に一定ピッチＰ1 で並んでいる。床板幅Ｗ0 の床板Ｂ1 は、床板Ｂ1 の長手方向Ｔが方向Ｓに対して直交するように並置され、床板Ｂ1 の幅方向Ｕの両端面１が隣接する各床板固定具Ａ1 に固定された状態で、根太材Ｊ上に敷設されている。なお、図１及び図４の符号４１，６２は、それぞれ根太材Ｊを固定する支持枠、及び支持枠と根太材Ｊを固定するビス類を示す。 The relationship between the floor board fixture A 1 and the floor board B 1 fixed on the joist J will be described. Hereinafter, the longitudinal direction of the long plate material is the direction T, the width direction is the direction U, and the longitudinal direction of the fixing material is the direction S. Here, the longitudinal direction and the width direction of the floor plate B 1 are the direction T, the direction U, and The longitudinal direction of the joist J may be simply referred to as direction S. First, as shown in FIG. 1 and FIG. 4, the floorboard fixture A 1 has a joist member J 1 such that the width direction of the fixing portion 10 of the floorboard fixture A 1 is parallel to the longitudinal direction S of the joist member J. In a state of being arranged on the top, they are fixed with screws 61 along the direction S, and are arranged on the joist J at a constant pitch P 1 . Floorboards floorboard width W 0 B 1, the longitudinal T of the floorboard B 1 is juxtaposed to be perpendicular to the direction S, the floor plate fixtures A 1 that both end surfaces 1 in the width direction U of the floorboard B 1 is adjacent It is laid on the joist timber J in a fixed state. 1 and 4 indicate a support frame for fixing the joist member J and screws for fixing the support frame and the joist member J, respectively.

次に、図３を用いて、床板固定具Ａ1 に係止された状態における床板Ｂ1 、及び床板固定具Ａ1 について説明する。まず、天然木或いは再生木からなる床板Ｂ1 において、端面１には、床板Ｂ1 の長手方向Ｔに沿って係止溝４が形成されていて、係止溝４を介して上下配置される上下各端面１ａ, １ｂは、下端面１ｂが内側に入り込んだ段差状になっている。床板Ｂ1 の端面１が上記のように段差状である理由は、根太材Ｊに固定された床板固定具Ａ1 の固定部１０との干渉を回避するためであるのと、床板Ｂ1 の相隣接する床板固定具Ａ1 への固定作業を容易にするためである。床板Ｂ1 が床板固定具Ａ1 で係止された状態では、係止溝４と下端面１ｂとで形成される出隅部５は、床板固定具Ａ1 の係止部２０に当接又は弾接している。また、床板Ｂ1 の両端面１に形成された係止溝４内には、隣接する各床板固定具Ａ1 の摺接部２１が収納されている。一つの床板固定具Ａ1 の両側に係止された二枚の床板Ｂ1 の各上端面１ａは、目地幅Ｗ1 の目地７を挟んで対向されている。係止溝４の幅及び深さ方向の寸法は、外方に突出した摺接部２１が収納されるのに必要十分であれば良い。また、上下各端面１ａ，１ｂの段差具合については、床板Ｂ1 の係止状態において、出隅部５が床板固定具Ａ1 の係止部２０に当接或いは弾接可能となるように、係止溝４の前記寸法と合わせて設定される。 Next, the floor board B 1 and the floor board fixture A 1 that are locked to the floor board fixture A 1 will be described with reference to FIG. First, in the floor board B 1 made of natural wood or recycled wood, the end face 1 is formed with a locking groove 4 along the longitudinal direction T of the floor board B 1 , and is arranged vertically via the locking groove 4. Each of the upper and lower end surfaces 1a and 1b has a step shape in which the lower end surface 1b enters the inside. The end face 1 of the floor plate B 1 is a step-like as described above reasons, and in the range in order to avoid interference with the fixing portion 10 of the fixed to the joist material J floor fixtures A 1, the floor plate B 1 This is for facilitating the fixing work to the floor plate fixtures A 1 adjacent to each other. In a state in which the floor board B 1 is locked by the floor board fixing tool A 1 , the protruding corner portion 5 formed by the locking groove 4 and the lower end surface 1b abuts on the locking part 20 of the floor board fixing tool A 1 or It is in elastic contact. Further, the sliding contact portions 21 of the respective floor plate fixtures A 1 adjacent to each other are accommodated in the locking grooves 4 formed on both end surfaces 1 of the floor plate B 1 . Each upper end face 1a of being locked on both sides of one floorboard fixture A 1 two floor plate B 1 represents, are opposite sides of the joint 7 of the joint width W 1. The dimensions of the locking groove 4 in the width and depth direction may be necessary and sufficient to accommodate the sliding contact portion 21 protruding outward. Further, the upper and lower end surfaces 1a, for the step condition 1b, the in the locked state of the floor plate B 1, as external corner portion 5 is contactable or elastic contact with the engaging portion 20 of the floor plate fixture A 1, It is set in accordance with the dimensions of the locking groove 4.

図３を用いて、床板Ｂ1 を係止した状態の床板固定具Ａ1 について説明する。床板固定具Ａ1 は、固定部１０が根太材Ｊ上に当接した状態で、ビス類６１を介して根太材Ｊに固定されている。一対の係止部２０は、それぞれ前記固定部１０と起立角度θ1 をなして起立し、床板Ｂ1 の出隅部５と当接或いは弾接状態で床板Ｂ1 を係止している。このとき、係止部２０の先端部に形成された摺接部２１は、床板Ｂ1 の係止溝４に収納されている。前記係止部２０が出隅部５と当接している場合には、前記起立角度θ1 は、床板固定具Ａ1 の非変形状態における起立角度θ0 に等しい。一方、前記係止部２０が出隅部５と弾接している場合には、起立角度θ1 は前記起立角度θ0 よりも小さくなって、係止部２０は僅かに立ち上がった状態に弾性変形されている。このため、係止部２０には弾性復元力が作用して、係止部２０は弾接している出隅部５を斜下方に向けて押圧する。従って、当接状態よりも弾接状態の方が床板Ｂ1 の係止は強固になっている。 The floor board fixture A 1 in a state where the floor board B 1 is locked will be described with reference to FIG. The floor plate fixture A 1 is fixed to the joist member J via screws 61 in a state where the fixing unit 10 is in contact with the joist member J. The pair of locking portions 20 stand up at an upright angle θ 1 with respect to the fixed portion 10, respectively, and lock the floor plate B 1 in contact or elastic contact with the protruding corner portion 5 of the floor plate B 1 . At this time, the sliding contact portion 21 formed at the tip portion of the locking portion 20 is accommodated in the locking groove 4 of the floorboard B 1. When the locking portion 20 is in contact with the protruding corner portion 5, the standing angle θ 1 is equal to the standing angle θ 0 in the non-deformed state of the floor board fixture A 1 . On the other hand, when the locking portion 20 is in contact with external corner portion 5 and the bullets, upright angle theta 1 is smaller than the upstanding angle theta 0, the locking portion 20 is elastically deformed in a state that rises slightly Has been. For this reason, an elastic restoring force acts on the latching portion 20, and the latching portion 20 presses the protruding corner portion 5 in elastic contact downward. Thus, the locking direction of elastic contact state of the floorboard B 1 than contact state has become stronger.

前記出隅部５が当接或いは弾接する係止部２０の位置については、前記出隅部５が係止できないような摺接部２１の上方部分では問題はあるが、それより下方であれば、前記係止部２０又は摺接部２１のどの位置に前記出隅部５が当接或いは弾接しても問題はない。ただし、床板Ｂ1 が根太材Ｊ上に係止された状態を安定的に保持する必要性を考慮すれば、床板固定具Ａ1 の摺接部２１の下端部、或いはその上下付近が望ましい。特に、床板Ｂ1 の浮き上がり防止の観点からでは、上記位置として前記下端部が最適である。なお、図３では、前記出隅部５が前記下端部より僅かに下側の係止部２０に弾接された状態が図示されている。図中Ｆ，Ｆ1 ，Ｆ2 はそれぞれ床板固定具Ａ1 の弾接力、該弾接力の垂直方向の分力、同水平方向の分力を示し、これらについては後述する。 There is a problem in the upper portion of the sliding contact portion 21 where the protruding corner portion 5 cannot be locked with respect to the position of the locking portion 20 with which the protruding corner portion 5 abuts or elastically contacts. There is no problem even if the protruding corner portion 5 abuts or elastically contacts any position of the locking portion 20 or the sliding contact portion 21. However, considering the necessity of stably holding the state where the floor plate B 1 is locked on the joist J, the lower end portion of the sliding contact portion 21 of the floor plate fixture A 1 or the vicinity thereof is desirable. In particular, from the viewpoint of preventing the floor board B 1 from being lifted, the lower end portion is optimal as the position. FIG. 3 shows a state in which the protruding corner portion 5 is elastically contacted with the locking portion 20 slightly below the lower end portion. In the figure, F, F 1 , and F 2 indicate the elastic contact force of the floor plate fixture A 1 , the vertical component force of the elastic contact force, and the horizontal component force, which will be described later.

次に、図３ないし図８を用いて、水平に設置された根太材Ｊ上に床板固定具Ａ1 を介して床板Ｂ1 を敷設する二種類の工程について説明し、その後、任意の一枚の床板Ｂ1 を根太材Ｊ上から脱着する工程について説明する。図５の（イ）ないし（ハ）は、隣接する床板固定具Ａ1 に一枚の床板Ｂ1 を傾斜姿勢で係止させていく工程を正面から順番に見た図である。図６は、隣接する床板固定具Ａ1 に一枚の床板Ｂ1 を直上から係止させる工程を正面から順番に見た図である。図７は、根太材Ｊの端部付近に敷設された床板Ｂ1 群の正面断面図である。図８の（イ）ないし（ハ）は、根太材Ｊ上に敷設された床板Ｂ1 群から一枚の床板Ｂ1 を取り外す工程を正面から順番に見た図である。なお、図５，図６，図８において、床板固定具Ａ1 及び根太材Ｊの断面表示は省略してある。また、図８（イ）では、床板固定具Ａ1 の係止部２０を出隅部５に当接させた状態で床板Ｂ1 を係止しているため、係止部２０の係止状態の起立角度θ1 は非変形状態の起立角度θ0 と等しくなっている。 Next, using FIG. 3 to FIG. 8, two kinds of processes for laying the floor board B 1 on the horizontally installed joist J through the floor board fixture A 1 will be described. A process of detaching the floor board B 1 from the joist J will be described. FIGS. 5A to 5C are views in which the steps of locking one floor board B 1 in an inclined posture to the adjacent floor board fixture A 1 are viewed in order from the front. FIG. 6 is a view in which the steps of locking one floor plate B 1 to the adjacent floor plate fixture A 1 from the top are sequentially viewed from the front. FIG. 7 is a front sectional view of the floor board B 1 group laid near the end of the joist J. FIG. To (b) of FIG. 8 (c) is a view in sequence the steps of removing a piece of floorboard B 1 from floor plate B 1 group laid on joists material J from the front. 5, 6, and 8, the cross-sectional display of the floor board fixture A 1 and the joist J is omitted. Further, in FIG. 8 (b), since the lock the floorboard B 1 being in contact with the locking portion 20 of the floor plate fixture A 1 to external corner portion 5, the locking state of the locking portion 20 upright angle theta 1 of is equal to the standing angle theta 0 undeformed state.

まず、図４を用いて、床板固定具Ａ1 の根太材Ｊ上への取付け工程について説明する。床板Ｂ1 を敷設後、隣り合う床板Ｂ1 の間に予め設定された目地幅Ｗ1 を有する目地７が形成されるように、各根太材Ｊの長手方向Ｓに対して床板固定具Ａ1 の幅方向が平行となるように床板固定具Ａ1 を配置し、所定のピッチＰ1 で床板固定具Ａ1 をビス類６１で固定していく。ピッチＰ1 は、床板Ｂ1 の床板幅Ｗ0 と前記目地幅Ｗ1 との和になるように定められる（Ｐ1 ＝Ｗ0 ＋Ｗ1 ）。また、床板固定具Ａ1 を固定していく際に、その都度ピッチＰ1 を定めながら、ドリルビス等を用いて根太材Ｊを穿孔すると同時に床板固定具Ａ1 を固定させていくことも可能であるが、予め前記方向Ｓに沿ってピッチＰ1 でビス孔を形成しておいた根太材Ｊを用いて、床板固定具Ａ1 の固定部１０に形成されたビス孔１１を前記ビス孔に対応させてビス類６１を挿通させることにより固定していくことも可能である。所定ピッチＰ1 でビス孔が予め形成された根太材Ｊを用いれば、経験や技術のない作業者でも、失敗することなく所定ピッチＰ1 で床板固定具Ａ1 を根太材Ｊ上に固定させていくことが可能であるし、根太材Ｊ上の任意のどの部分からでも床板固定具Ａ1 の固定作業を容易に開始できる。 First, the process of attaching the floor board fixture A 1 onto the joist J will be described with reference to FIG. As after laying the floor plate B 1, joint 7 having a joint width W 1 which is previously set between the floor panel B 1 adjacent is formed, the floor plate fixture A 1 with respect to the longitudinal direction S of each joist member J in the width direction places the floor fixtures a 1 in parallel, will be fixed with screws such 61 a floor fixtures a 1 at a predetermined pitch P 1. The pitch P 1 is determined to be the sum of the floor board width W 0 of the floor board B 1 and the joint width W 1 (P 1 = W 0 + W 1 ). Also, when going to secure the floor plate fixture A 1, while determined each time the pitch P 1, is also possible to go to fix the floor fixtures A 1 and simultaneously perforate the joist member J with drill screws, etc. The screw hole 11 formed in the fixing portion 10 of the floor board fixture A 1 is used as the screw hole by using the joist material J in which the screw holes are previously formed at the pitch P 1 along the direction S. It is also possible to fix by inserting the screws 61 correspondingly. If the joist J having the screw holes formed in advance at the predetermined pitch P 1 is used, even an operator without experience or skill can fix the floor plate fixture A 1 on the joist J with the predetermined pitch P 1 without failure. The fixing work of the floor board fixture A 1 can be easily started from any arbitrary part on the joist J.

次に、図５を用いて、根太材Ｊ上に固定されてピッチＰ1 で隣接する床板固定具Ａ1 に床板Ｂ1 を係止させて、床板Ｂ1 を根太材Ｊ上に固定していく工程について説明する。ここで、床板Ｂ1 を係止する前の非変形状態の床板固定具Ａ1 において、固定部１０に対する係止部２０の起立角度はθ0 である。また、摺接部２１の水平方向に対して最も外方に突出した部分と、該突出方向に隣接した床板固定具Ａ1 の摺接部２１における上記部分との距離（間隔）を床板固定具Ａ1 の「開口幅Ｄ」と定め、床板固定具Ａ1 の非変形状態（即ち、床板Ｂ1 を係止していない状態）における開口幅をＤ0 とする。 Next, with reference to FIG. 5, is fixed on the joists material J and the floor plate B 1 is engaged in the floorboard fixture A 1 adjacent in pitch P 1, to secure the floor plate B 1 on joists material J The following steps will be described. Here, in the floor plate fixture A 1 in a non-deformed state before the floor plate B 1 is locked, the standing angle of the locking portion 20 with respect to the fixing portion 10 is θ 0 . Further, the distance (interval) between the portion of the sliding contact portion 21 that protrudes outward in the horizontal direction and the portion of the sliding contact portion 21 of the floor plate fixing tool A 1 adjacent to the protruding direction is determined as the floor plate fixing tool. It is defined as “opening width D” of A 1, and the opening width in the non-deformed state of the floor board fixture A 1 (that is, the state where the floor board B 1 is not locked) is D 0 .

上記の状態で隣接している二つの床板固定具Ａ1 に、一枚の床板Ｂ1 を係止させる。その手順を以下に示す。最初に、床板Ｂ1 を水平方向に対して斜めに傾けながら、水平より低く傾いた側（図５では紙面左側）の端面１の係止溝４に、床板固定具Ａ1 の係止部２０先端の摺接部２１が挿入されるように、床板Ｂ1 を前記係止部２０に向けて落とし込む。水平より低く傾いた側の出隅部５が床板固定具Ａ1 の係止部２０に当接したら、その傾斜姿勢のまま床板Ｂ1 を更に斜下方に落とし込んで、床板固定具Ａ1 の係止部２０を押圧する。このとき、該係止部２０は起立角度θが非変形状態の起立角度θ0 よりも小さくなるように弾性変形するので、床板固定具Ａ1 の開口幅Ｄは非変形状態の開口幅Ｄ0 よりも大きくなる。該開口幅Ｄが広がるので、前記出隅部５付近を中心として床板Ｂ1 を下方に回動させ、水平より高く傾いている側（図５では紙面右側）の下端面１ｂと下面３との出隅部６を、隣接の床板固定具Ａ1 の摺接部２１に当接させる。前記出隅部６が前記摺接部２１に当接したら、更に下方へ押し込む。すると、同側の床板固定具Ａ1 の係止部２０は、起立角度θが非変形状態の起立角度θ0 よりも僅かに小さくなるように弾性変形していき、前記出隅部６、続けて前記下端面１ｂは摺接部２１の外周面に摺接しながら下方に滑り込んでいく。この結果、床板Ｂ1 の下面３全体が根太材Ｊ上に当接し、床板Ｂ1 は隣接する床板固定具Ａ1 間に完全に嵌まり込む。それと同時に、床板Ｂ1 の両端面１側の床板固定具Ａ1 の係止部２０が、自身の弾性復元力にて起立角度θを非変形状態の起立角度θ0 に戻すように復元するので、床板Ｂ1 の各端面１側の出隅部５は、それぞれ各床板固定具Ａ1 の係止部２０に当接か或いは弾接した状態で係止され、このとき前記各床板固定具Ａ1 の摺接部２１は、床板Ｂ1 の各側の係止溝４によって収納される。以上の工程により、床板Ｂ1 は、床板固定具Ａ1 を介して根太材Ｊ上に固定される。 One floor board B 1 is locked to two floor board fixtures A 1 adjacent in the above state. The procedure is shown below. First, while the floor plate B 1 is inclined with respect to the horizontal direction, the locking portion 20 of the floor plate fixture A 1 is inserted into the locking groove 4 of the end surface 1 on the side inclined lower than the horizontal (left side in FIG. 5). The floor plate B 1 is dropped toward the locking portion 20 so that the sliding contact portion 21 at the tip is inserted. After contact with external corner portions 5 of the inclined lower than the horizontal side is the engagement portion 20 of the floor plate fixture A 1, the left floor panel B 1 of the inclined position further plunge obliquely downward, the engagement of the floor plate fixture A 1 The stop 20 is pressed. At this time, since the locking portion 20 is elastically deformed so that the standing angle θ is smaller than the standing angle θ 0 in the non-deformed state, the opening width D of the floor board fixture A 1 is the opening width D 0 in the non-deformed state. Bigger than. Since the opening width D is widened, the floor board B 1 is rotated downward about the vicinity of the protruding corner 5, and the lower end surface 1 b and the lower surface 3 on the side inclined higher than the horizontal (right side in FIG. 5). The protruding corner portion 6 is brought into contact with the sliding contact portion 21 of the adjacent floor board fixture A 1 . When the protruding corner portion 6 comes into contact with the sliding contact portion 21, it is pushed further downward. Then, the locking portion 20 of the floor-side fixture A 1 on the same side is elastically deformed so that the standing angle θ is slightly smaller than the standing angle θ 0 in the non-deformed state, and the protruding corner portion 6 continues. The lower end surface 1b slides downward while sliding on the outer peripheral surface of the sliding contact portion 21. As a result, the lower surface 3 whole floorboard B 1 is in contact on joists material J, the floorboard B 1 represents snaps completely fitted between the floor plate fixture A 1 adjacent. At the same time, the locking portion 20 of the floor plate fixture A 1 both end faces 1 side of the floor plate B 1 is, so to restore at its elastic restoring force to return the upright angle theta to the standing angle theta 0 undeformed state The protruding corners 5 on the end face 1 side of the floor board B 1 are locked in contact with or in elastic contact with the locking parts 20 of the floor board fixing tools A 1 , respectively. One sliding contact portion 21 is accommodated by the locking groove 4 on each side of the floor board B 1 . Through the above steps, the floor board B 1 is fixed on the joist J through the floor board fixture A 1 .

前記出隅部５が前記係止部２０によって係止された状態において、床板固定具Ａ1 の開口幅、及び係止部２０の起立角度をそれぞれＤ1 ，θ1 とすれば、前記出隅部５が係止部２０に対して当接状態で係止されている場合には、前記開口幅Ｄ1 、及び前記起立角度θ1 は、非変形状態の開口幅Ｄ0 、及び起立角度θ0 に等しい。また、前記出隅部５が弾接状態で係止されている場合には、前記開口幅Ｄ1 は非変形状態の開口幅Ｄ0 よりも大きく、前記起立角度θ1 は非変形状態の起立角度θ0 よりも小さい。前記係止部２０の起立角度θ1 が非変形状態の起立角度θ0 よりも小さいので、前記係止部２０では非変形状態まで変形が完全に復元しておらず、前記係止部２０の弾性復元力は残存した状態にある。上記残存した弾性復元力を弾接力Ｆとすれば、該弾接力Ｆが作用することによって、前記係止部２０は自身と弾接している出隅部５を斜下方に向けて押圧する。前記弾接力Ｆのうち垂直方向の分力Ｆ1 が、根太材Ｊに対して床板Ｂ1 を押付けて固定するように作用するため、当接状態よりも弾接状態の方が床板Ｂ1 の係止は強固になる。また、前記出隅部５が、床板固定具Ａ1 の摺接部２１の下端部に当接或いは弾接している場合には、前記摺接部２１が床板Ｂ1 の係止溝４に係止され、前記出隅部５の上方への動きが阻害されるので、床板Ｂ1 の浮き上がりが最も効果的に防止される。 In the state where the protruding corner portion 5 is locked by the locking portion 20, if the opening width of the floor plate fixture A 1 and the standing angle of the locking portion 20 are D 1 and θ 1 , respectively, the protruding corner will be described. When the portion 5 is locked in contact with the locking portion 20, the opening width D 1 and the standing angle θ 1 are the non-deformed opening width D 0 and the standing angle θ. Equal to 0 . When the protruding corner 5 is locked in an elastic contact state, the opening width D 1 is larger than the opening width D 0 in the non-deformed state, and the standing angle θ 1 is set up in the non-deformed state. The angle is smaller than 0 . Since the standing angle θ 1 of the locking part 20 is smaller than the standing angle θ 0 in the non-deformed state, the deformation is not completely restored in the locking part 20 until the non-deformed state. The elastic restoring force remains. If the remaining elastic restoring force is the elastic contact force F, the elastic contact force F acts, so that the locking portion 20 presses the protruding corner portion 5 in elastic contact with itself downward. Component force F 1 in the vertical direction of the elastic contact force F is, with respect to joists material J for acting to secure by pressing the floor plate B 1, toward the elastic contact state than the contact state of the floorboard B 1 The lock becomes strong. Further, when the protruding corner portion 5 is in contact with or elastically contacts the lower end portion of the sliding contact portion 21 of the floor plate fixture A 1 , the sliding contact portion 21 is engaged with the locking groove 4 of the floor plate B 1. Since it is stopped and the upward movement of the protruding corner portion 5 is hindered, the floor board B 1 is most effectively prevented from being lifted.

また、前記弾接力Ｆのうち水平方向の分力Ｆ2 は、床板Ｂ1 の両端面１において、相等しいために互いに相殺される。前記分力Ｆ2 が均衡することによって、根太材Ｊの長手方向Ｓに沿って隣接する各床板固定具Ａ1 の中間位置に、即ち、床板固定具Ａ1 の開口幅Ｄ1 の中点に当たる位置に床板Ｂ1 の幅方向Ｕの中央部が一致するように、床板Ｂ1 が配置される。従って、敷設される床板Ｂ1 の幅方向Ｕの位置決めは、同方向Ｕ、即ち前記方向Ｓに沿って隣接配置された各床板固定具Ａ1 の弾接力Ｆが互いに等しくなり均衡することによって行われる。そして、床板固定具Ａ1 を根太材Ｊ上に固定するピッチＰ1 と、床板Ｂ1 の幅Ｗ0 が一定である限り、相隣接する床板Ｂ1 の端面１同士の間隔である目地幅Ｗ1 は、全ての床板Ｂ1 において一定となる。 Further, the component force F 2 in the horizontal direction of the elastic contact force F, in both end faces 1 of the floor plate B 1, are offset to one another for equal phases. When the component force F 2 is balanced, it hits the middle position of the floor plate fixtures A 1 adjacent to each other along the longitudinal direction S of the joist J, that is, the midpoint of the opening width D 1 of the floor plate fixture A 1. as the central portion in the width direction U of the floorboard B 1 is coincident to the position, the floor plate B 1 is being placed. Accordingly, the positioning of the floor board B 1 to be laid in the width direction U is performed by equalizing and balancing the elastic contact forces F of the floor board fixtures A 1 arranged adjacent to each other in the same direction U, that is, the direction S. Is called. As long as the pitch P 1 for fixing the floor board fixture A 1 on the joist J and the width W 0 of the floor board B 1 are constant, the joint width W is the distance between the end faces 1 of the adjacent floor boards B 1. 1 is constant in all floor boards B 1 .

次に、図６を用いて、別の手法にて床板Ｂ1 を根太材Ｊ上に固定する工程を説明する。上記のように前記床板Ｂ1 を傾斜させて床板固定具Ａ1 に係止させる以外の方法としては、以下の方法も可能である。まず、前記床板Ｂ1 を水平に載置して、床板Ｂ1 両端面１の出隅部６或いは出隅部付近の下面３を、隣接する床板固定具Ａ1 の摺接部２１に当接させる。次に、前記床板Ｂ1 の上面２上に作業者が乗り上げ、勢いをつけて前記床板Ｂ1 を踏みつける等の手段を講じて、前記床板Ｂ1 を押し下げるのに十分な力を直上から前記床板Ｂ1 に与える。この結果、前記床板Ｂ1 は、各出隅部６及び下端面１ｂを順に摺接部２１と摺接させながら、前記係止部２０の起立角度θを小さく、また、床板固定具Ａ1 の開口幅Ｄを大きくするように前記係止部２０を弾性変形させていく。これによって、床板Ｂ1 は垂直方向に押し下げられて、隣接する床板固定具Ａ1 間に挟め込まれる。これと同時に、前記係止部２０は、弾性復元力によって、床板Ｂ1 の両端面１の出隅部５と当接か或いは弾接するまで弾性変形を復元させて、起立角度θ1 をなして前記出隅部５を係止し、前記摺接部２１は前記床板Ｂ1 の係止溝４に収納される。 Next, with reference to FIG. 6, illustrating a step of fixing the floor plate B 1 on joists material J in a separate approach. The following method is also possible as a method other than the method in which the floor plate B 1 is inclined and locked to the floor plate fixture A 1 as described above. First, the floor plate B 1 is placed horizontally, and the protruding corner portion 6 of the both end surfaces 1 of the floor plate B 1 or the lower surface 3 near the protruding corner portion is brought into contact with the sliding contact portion 21 of the adjacent floor plate fixture A 1 . Let Next, the operator rides on the top surface 2 of the floor plate B 1, taking steps such as stomp the floor plate B 1 with the momentum, the floor from directly above a sufficient force to depress the floor plate B 1 give to B 1. As a result, the floor plate B 1 reduces the rising angle θ of the locking portion 20 while bringing the protruding corner portions 6 and the lower end surface 1b into sliding contact with the sliding contact portion 21 in turn, and the floor plate fixing tool A 1 is configured to be The locking portion 20 is elastically deformed so as to increase the opening width D. Thereby, the floor board B 1 is pushed down in the vertical direction and is sandwiched between the adjacent floor board fixtures A 1 . At the same time, the locking portion 20 restores elastic deformation by elastic restoring force until it comes into contact or elastic contact with the protruding corner portion 5 of the both end faces 1 of the floor board B 1 , thereby forming the rising angle θ 1 . The protruding corner portion 5 is locked, and the sliding contact portion 21 is accommodated in the locking groove 4 of the floor plate B 1 .

以上、いずれかの工程を繰り返し実施することによって、水平に設置された根太材Ｊ上に順に固定していき、水平な床板Ｂ1 群を形成していく。図７に示すように、敷設された床板Ｂ1 群は、床板幅Ｗ0 の床板Ｂ1 が目地幅Ｗ1 の目地７を有して、根太材Ｊの長手方向Ｓに沿ってピッチＰ1 で根太材Ｊ上に連続的に固定された床板構造となっている。そして、各床板Ｂ1 の両端面１に形成された係止溝４と下端面１ｂとで形成される出隅部５が床板固定具Ａ1 と当接或いは弾接することによって、床板Ｂ1 は床板固定具Ａ1 に係止され、床板Ｂ1 の根太材Ｊ上への固定が可能となっている。なお、根太材Ｊをビス類６２で固定した支持枠４１において、敷設された前記床板Ｂ1 群を敷設予定場所に設置する場合には、支持枠４１を介して前記床板Ｂ1 群が固定された根太材Ｊをビス類６３等で地面（床面）Ｇに固定するか、或いは、支持枠４１の各所に支持脚を設け、該支持脚を立脚させて前記床板Ｂ1 群を地面Ｇから所定高さを有して設置する。前記支持脚の高さ方向を調節することにより、前記床板Ｂ1 群の設置高さを変えることが可能である。また、地面Ｇが斜面である場合、或いは、床板Ｂ1 群をスロープ状に傾斜させる場合等において、根太材Ｊを水平面に対して傾斜した状態で設置し、その上に床板Ｂ1 を固定する際は、上記した床板Ｂ1 の固定方法において、「水平方向」を「根太材Ｊの長手方向Ｓ」と読み替えれば良い。これは、以下に説明する床板Ｂ1 の取外し方についても同様である。 As described above, by repeatedly performing one of the steps, it is fixed in order on the joist J installed horizontally, and a horizontal floor board B 1 group is formed. As shown in FIG. 7, is laid floorboards B 1 group, floor plate B 1 of the floor plate width W 0 is a joint 7 of joint width W 1, the pitch P 1 in the longitudinal direction S of the joist material J The floor board structure is continuously fixed on the joists. Then, the floor plate B 1 is formed by contacting or elastically contacting the floor plate fixture A 1 with the protruding corner portion 5 formed by the locking groove 4 and the lower end surface 1b formed on both end surfaces 1 of each floor plate B 1. Locked to the floor board fixture A 1 , the floor board B 1 can be fixed onto the joist J. In addition, in the support frame 41 in which the joist J is fixed with the screws 62, when the laid floor board B 1 group is installed at a planned laying place, the floor board B 1 group is fixed via the support frame 41. The floor joists J are fixed to the ground (floor surface) G with screws 63 or the like, or support legs are provided at various points of the support frame 41, and the support legs are erected to remove the floor board B 1 group from the ground G. Install with a predetermined height. It is possible to change the installation height of the floor board B 1 group by adjusting the height direction of the support legs. In addition, when the ground G is a slope or when the floor board B 1 group is inclined in a slope shape, the joist J is installed in an inclined state with respect to the horizontal plane, and the floor board B 1 is fixed thereon. At this time, in the above-described fixing method of the floor board B 1 , the “horizontal direction” may be read as “the longitudinal direction S of the joist J”. The same applies to the method of removing the floor board B 1 described below.

次に、図６及び図８を用いて、敷設された床板Ｂ1 群から、任意の一枚の床板Ｂ1 を脱着する工程について説明する。まず、敷設された床板Ｂ1 群のうち、或る任意の床板Ｂ1 を取り外すには、以下の手順で行えばよい。まず、当該床板Ｂ1 を略目地幅Ｗ1 分だけ床板Ｂ1 の幅方向Ｕ、即ち方向Ｓに沿ってスライドさせて、当該床板Ｂ1 の両端面１の出隅部５を係止している各床板固定具Ａ1 のうち、一方側の床板固定具Ａ1 の係止部２０を押圧して、起立角度θが係止状態の起立角度θ1 よりも小さくなるように前記係止部２０を弾性変形させ、床板Ｂ1 の幅方向Ｕに沿って隣接する床板固定具Ａ1 間の開口幅Ｄを係止状態の開口幅Ｄ1 よりも広くする。この結果、当該床板Ｂ1 の他方側の床板固定具Ａ1 において、該床板固定具Ａ1 の摺接部２１を収納していた係止溝４が該床板固定具Ａ1 から離れるので、当該床板Ｂ1 の係止溝４に対する係止を緩めるか或いは解除した状態となる。次に、前記スライドにより係止部２０を押圧した側を中心として床板Ｂ1 を回動させるようにして、前記係止が緩んだ状態にある側の当該床板Ｂ1 の端部を持ち上げ、当該床板Ｂ1 を水平方向に対して傾斜させていくと、持ち上げられた側の下端面１ｂは該摺接部２１に摺接する。該摺接部２１と連接する係止部２０は、起立角度θを小さくする方向に僅かに弾性変形しながら、前記下端面１ｂを該摺接部２１に沿って滑り上げていく。この結果、持ち上げられた側の床板Ｂ1 の端部は完全に床板固定具Ａ1 から外れ、それと同時に、前記係止部２０は弾性復元力により変形は復元し、非変形状態の起立角度θ0 になるまで起立する。また、前記係止が解除された状態にある場合、同状態にある側の当該床板Ｂ1 の端部を持ち上げると、前記端部は下端面１ｂが摺接部２１に接触することなく持ち上がる。この結果、持ち上げられた側の床板Ｂ1 の端部は、敷設された状態で隣接する床板Ｂ1 の上面２よりも上方まで持ち上げ可能となる。従って、この傾斜方向に沿って当該床板Ｂ1 を引き上げると、隣接する両床板Ｂ1 は固定されたままで、当該床板Ｂ1 のみが外される。なお、当該床板Ｂ1 が引き上げられるにつれて、当該床板Ｂ1 の幅方向Ｕへのスライドにより弾性変形していた側の床板固定具Ａ1 の係止部２０は、弾性復元力によって非変形状態に戻っていく。なお、取り外した床板Ｂ1 を元の位置に戻して再固定するには、上記したように、床板Ｂ1 の敷設工程と同じ手順で実施すればよい。 Next, with reference to FIGS. 6 and 8, from the laid floorboard B 1 group, steps of desorbing any one piece of the floorboard B 1. First, in order to remove an arbitrary floor board B 1 from the laid floor boards B 1 group, the following procedure may be used. First, the width U of the floorboard B 1 only substantially joint width W 1 minute floor plate B 1, i.e., by sliding along the direction S, engages the external corner portions 5 of the end faces 1 of the floor plate B 1 each of the floor plate fixture a 1, whereas presses the side of the floor plate fixture a 1 of the engaging portion 20, the locking portion to be smaller than the upstanding angle theta 1 of the upright angle theta is locked state are 20 is elastically deformed so that the opening width D between the floor plate fixtures A 1 adjacent along the width direction U of the floor plate B 1 is wider than the opening width D 1 in the locked state. As a result, the floor plate fixture A 1 on the other side of the floor plate B 1, since the locking grooves 4 which used to house the sliding contact portion 21 of the floor plate fasteners A 1 moves away from the floor plate fixture A 1, the The locking of the floor board B 1 with respect to the locking groove 4 is loosened or released. Next, the floor plate B 1 is rotated around the side where the locking portion 20 is pressed by the slide, and the end of the floor plate B 1 on the side where the locking is loosened is lifted, When the floor board B 1 is inclined with respect to the horizontal direction, the lower end surface 1 b on the raised side comes into sliding contact with the sliding contact portion 21. The locking portion 20 connected to the sliding contact portion 21 slides up the lower end surface 1b along the sliding contact portion 21 while being slightly elastically deformed in the direction of decreasing the rising angle θ. As a result, the end of the raised floor board B 1 is completely disengaged from the floor board fixture A 1 , and at the same time, the locking part 20 is deformed by the elastic restoring force, and the standing angle θ in the non-deformed state Stand up until zero . In the state where the locking is released, when the end of the floor plate B 1 on the side in the same state is lifted, the end is lifted without the lower end surface 1b contacting the sliding contact portion 21. As a result, the end portion of the floor panel B 1 of the raised side, the liftable up above the upper surface 2 of the floor plate B 1 adjacent to each other in the laid state. Therefore, when pulling the floor plate B 1 along the inclined direction, both the floorboard B 1 adjacent remains fixed, only the floor panel B 1 is disengaged. As the floor board B 1 is pulled up, the locking portion 20 of the floor board fixture A 1 on the side that has been elastically deformed by sliding the floor board B 1 in the width direction U is brought into an undeformed state by the elastic restoring force. Go back. Incidentally, the re-fixed back floorboards B 1 removed to the original position, as described above, it may be carried out in the same procedure as laid process of the floorboard B 1.

次に、図９を用いて、床板Ｂ1 の目地７の幅Ｗ1 について説明する。図９（イ）及び（ロ）は、目地幅Ｗ1 ，Ｗ2 をそれぞれ有して床板Ｂ1 が固定され、敷設された状態における床板Ｂ1 群の正面断面図である。なお、床板固定具Ａ1 及び根太材Ｊの断面表示は略してある。床板Ｂ1 の目地７の幅Ｗ1 は、一般的には３ｍｍ，５ｍｍ，１０ｍｍがある。目地幅Ｗ1 が大きい場合には、見栄えが悪いだけでなく、床板Ｂ1 群の床下への落下物も多く、また、つま先を目地７に引っ掛けたり、ハイヒールのヒール部分が前記目地７内に嵌る等で歩行時に危険である。このため、床板Ｂ1 の自然発生的な膨張分や反り分を考慮しつつ、なるべく目地幅Ｗ1 を小さくできることが望ましく、最適な目地幅Ｗ1 として３ないし５ｍｍが採用されることが多い。本発明の床板固定具Ａ1 では、３ないし５ｍｍ内で目地幅Ｗ1 を容易に変えることが可能である。即ち、ピッチＰ1 は、床板幅Ｗ0 と目地幅Ｗ1 との和であるから、目地幅Ｗ1 をＷ1 より狭い目地幅Ｗ2 に変える場合（Ｗ2 ＜Ｗ1 ）には、前記床板固定具Ａ1 を根太材Ｊ上に固定するピッチＰ1 を狭くするだけでよい。また、目地幅Ｗ2 を有して床板Ｂ1 が係止された状態にある床板固定具Ａ1 のピッチ、及び係止部２０の起立角度をそれぞれＰ2 ，θ2 とすれば、ピッチＰ2 とピッチＰ1 の関係は、Ｐ2 ＜Ｐ1 であり、また、起立角度θ2 と起立角度θ1 、及び非変形状態の起立角度θ0 との関係は、θ2 ＜θ1 ≦θ0 となる。従って、起立角度θ1 がθ0 と等しい状態、即ち係止部２０が床板Ｂ1 の出隅部５と当接状態で床板Ｂ1 を根太材Ｊ上に固定するような床板固定具Ａ1 の場合には、目地幅をＷ1 よりも小さいＷ2 に調整すると、前記係止部２０は前記出隅部５と弾接するようになるので床板固定具Ａ1 はより強固に床板Ｂ1 を係止可能となる。また、前記起立角度θ1 がθ0 よりも小さい状態、即ち係止部２０が床板Ｂ1 の出隅部５と弾接状態で床板Ｂ1 を根太材Ｊ上に固定するような床板固定具Ａ1 の場合には、目地幅をＷ1 よりも小さいＷ2 に調整すると、係止部２０にはより大きな弾性復元力が残存するので、より大きな弾接力Ｆが前記係止部２０に作用する。従って、前記床板固定具Ａ1 は、一層強固に床板Ｂ1 を係止できるようになる。 Next, with reference to FIG. 9, a description will be given width W 1 of the joint 7 of the floorboard B 1. FIGS. 9A and 9B are front sectional views of the floor board B 1 group having the joint widths W 1 and W 2 and the floor board B 1 fixed and laid. The cross-sectional view of the floor plate fixtures A 1 and joist material J is are short. The width W 1 of the joint 7 of the floorboard B 1 represents, in general some 3 mm, 5 mm, is 10 mm. When the joint width W 1 is large, not only the appearance is bad, but there are also many falling objects of the floor board B 1 group under the floor. It is dangerous when walking because it fits. For this reason, it is desirable that the joint width W 1 can be made as small as possible while taking into account the spontaneous expansion and warpage of the floor board B 1 , and 3 to 5 mm is often adopted as the optimum joint width W 1 . In the floor board fixture A 1 of the present invention, the joint width W 1 can be easily changed within 3 to 5 mm. That is, since the pitch P 1 is the sum of the floor board width W 0 and the joint width W 1 , when the joint width W 1 is changed to the joint width W 2 narrower than W 1 (W 2 <W 1 ), It is only necessary to narrow the pitch P 1 for fixing the floor board fixture A 1 on the joist J. Further, if the pitch of the floor plate fixture A 1 having the joint width W 2 and the floor plate B 1 being locked and the rising angle of the locking portion 20 are P 2 and θ 2 , the pitch P 2 and the pitch P 1 are P 2 <P 1 , and the relationship between the rising angle θ 2 and the rising angle θ 1 and the rising angle θ 0 in the non-deformed state is θ 2 <θ 1 ≦ θ 0 . Therefore, the state equivalent to the upright angle theta 1 is theta 0, i.e. the locking portion 20 is floor fixtures A 1 so as to secure the floor plate B 1 on joists material J in abutment with the external corner portion 5 of the floor plate B 1 In this case, when the joint width is adjusted to W 2 smaller than W 1 , the locking portion 20 comes into elastic contact with the protruding corner portion 5, so that the floor plate fixture A 1 is more firmly attached to the floor plate B 1 . It can be locked. Further, the upright angle theta 1 is less than theta 0 state, i.e. floor fixtures such as to secure the floor plate B 1 on joists material J locking portion 20 at the outer corner portion 5 and the elastic contact state of the floorboard B 1 In the case of A 1 , when the joint width is adjusted to W 2 smaller than W 1 , a larger elastic restoring force remains in the locking portion 20, so a larger elastic contact force F acts on the locking portion 20. To do. Therefore, the floor board fixture A 1 can lock the floor board B 1 more firmly.

次に、図１０及び図１１を用いて、固定された床板Ｂ1 の長手方向へのずれを確実に防止する方法について説明する。図１０（イ）及び（ロ）は、それぞれ床板Ｂ1 の非固定時、及び固定時において、弾性変形維持部材５１が嵌着された床板固定具Ａ1 を正面から見た断面図である。図１１（イ）及び（ロ）は、一方側の係止部２０の一部にゴム部５２、及びバリ部５３がそれぞれ形成された床板固定具Ａ1 の全体斜視図である。床板固定具Ａ1 を介して根太材Ｊ上に敷設された床板Ｂ1 群において、該床板Ｂ1 群上に長期間に亘り過剰な歩行や衝撃がかかると、各床板固定具Ａ1 に係止された床板Ｂ1 は、床板Ｂ1 の長手方向Ｔに沿ってずれを生じる可能性がある。これを防止するための方法を以下に示す。まず、一つ目の方法は、ばね材で形成された弾性変形維持部材５１を備えた床板固定具Ａ1 を用いる点である。当該弾性変形維持部材５１は、両端部５１ｂが床板固定具Ａ1 の対向形成された各係止部２０或いは摺接部２１内面にそれぞれ嵌着され、中央部５１ａは弓形状の架橋状態で配置された形状である。該弾性変形維持部材５１の中央部５１ａを持ち上げて上側が突出するような弓形状に撓ませた場合には、前記弾性変形維持部材５１の両端部５１ｂを介して、前記床板固定具Ａ1 の係止部２０が起立角度θ1 を小さくする方向に弾性変形するため、前記床板固定具Ａ1 による床板Ｂ1 の係止が緩和された状態となる。また、該中央部５１ａを押し下げて下側が突出するような弓形状に撓ませた場合には、前記弾性変形維持部材５１の両端部５１ｂを介して、前記床板固定具Ａ1 の係止部２０には床板Ｂ1 を斜下方に押圧する力が加わる。このため、前記各係止部２０の弾性変形状態が長期に亘って維持され、床板Ｂ1 の出隅部５に対する前記係止部２０の弾接状態も維持される。従って、前記床板固定具Ａ1 単体の場合よりも、より大きな力で床板Ｂ1 を長期間に亘って押圧し、床板Ｂ1 の根太材Ｊ上への係止状態を維持できるので、床板Ｂ1 を長期間使用しても床板Ｂ1 の長手方向Ｔへのずれは防止される。 Next, a method for reliably preventing the displacement of the fixed floor board B 1 in the longitudinal direction will be described with reference to FIGS. 10 and 11. FIGS. 10A and 10B are cross-sectional views of the floor board fixture A 1 fitted with the elastic deformation maintaining member 51 as viewed from the front when the floor board B 1 is not fixed and when it is fixed, respectively. 11A and 11B are overall perspective views of the floor board fixture A 1 in which a rubber part 52 and a burr part 53 are respectively formed on a part of the locking part 20 on one side. In the floor board B 1 group laid on the joist J through the floor board fixture A 1 , if excessive walking or impact is applied to the floor board B 1 group for a long time, the floor board fixture A 1 There is a possibility that the stopped floor board B 1 is displaced along the longitudinal direction T of the floor board B 1 . A method for preventing this will be described below. First, the first method is to use a floor plate fixture A 1 provided with an elastic deformation maintaining member 51 formed of a spring material. The elastic deformation holding member 51, both end portions 51b are fitted respectively in the opposite form each engaging portion 20 or the sliding contact portion 21 the inner surface was floorboards fastener A 1, the central portion 51a is disposed in a crosslinked state of arcuate Shape. When the central portion 51a of the elastic deformation maintaining member 51 is lifted and bent into a bow shape such that the upper side protrudes, the floor plate fixture A 1 of the floor plate fixture A 1 is interposed via both end portions 51b of the elastic deformation maintaining member 51. Since the locking part 20 is elastically deformed in the direction of decreasing the rising angle θ 1 , the locking of the floor board B 1 by the floor board fixing tool A 1 is relaxed. Also, the when the lower depress the central portion 51a is flexed to arcuate as to protrude through the both end portions 51b of the elastic deformation holding member 51, the floor plate fixture A 1 of the locking part 20 A force for pressing the floor board B 1 obliquely downward is applied. For this reason, the elastic deformation state of each locking part 20 is maintained over a long period of time, and the elastic contact state of the locking part 20 with respect to the protruding corner part 5 of the floor board B 1 is also maintained. Accordingly, the floor plate B 1 can be pressed with a greater force for a longer period of time than in the case of the floor plate fixture A 1 alone, and the locked state of the floor plate B 1 on the joist J can be maintained. Even if 1 is used for a long time, the shift of the floor board B 1 in the longitudinal direction T is prevented.

また、固定された床板Ｂ1 の長手方向へのずれを防止する別の方法としては、摩擦力を利用する方法がある。即ち、床板固定具Ａ1 の片側一方の係止部２０の一部に摩擦力の大きい材質であるゴム材を貼り付けてゴム部５２を形成するか、前記係止部２０の一部の表面状態を粗くして、摩擦力を有するバリ部５３を形成する方法である。前記ゴム部５２或いはバリ部５３は、床板Ｂ1 の出隅部５が当接或いは弾接する位置を含むように、片側一方の前記係止部２０の外側面の一部に形成される。前記ゴム部５２或いはバリ部５３を前記係止部２０の片側一方にのみ設ける理由は、床板Ｂ1 の着脱のし易さのためである。前記ゴム部５２或いはバリ部５３を有する床板固定具Ａ1 を用いて床板Ｂ1 を根太材Ｊ上に固定する際は、まず、ゴム部５２或いはバリ部５３が形成されている側の摺接部２１に前記床板Ｂ1 の係止溝４が挿入されるように床板Ｂ1 を斜め下方に落とし込み、前記床板Ｂ1 の出隅部５を係止部２０に当接させ、押圧する。次に、水平より高く傾いた側の出隅部５及び下端面１ｂを、隣接する床板固定具Ａ1 の摺接部２１に摺接させて、床板Ｂ1 の下面３が根太材Ｊ上に当接するまで下方に滑らせていけばよい。なお、固定された床板Ｂ1 を取り外す際は、上記と反対の手順で行えばよい。前記出隅部５及び下端面１ｂが摺接する側の摺接部２１及び係止部２０には、前記ゴム部５２或いはバリ部５３が形成されてないので、床板Ｂ1 の着脱は容易に行える。 Further, as another method for preventing the fixed floor board B 1 from shifting in the longitudinal direction, there is a method using a frictional force. That is, the rubber part 52 is formed by attaching a rubber material, which is a material having a large frictional force, to a part of the one locking part 20 on one side of the floor plate fixture A 1 , or a part of the surface of the locking part 20. In this method, the burrs 53 having a frictional force are formed by roughening the state. The rubber part 52 or the burr part 53 is formed on a part of the outer surface of the one locking part 20 on one side so as to include a position where the protruding corner part 5 of the floor board B 1 abuts or elastically contacts. The reason for the rubber portion 52 or the burr portion 53 provided only on one side of the locking portion 20 is for detachably ease of floorboard B 1. When the floor board B 1 is fixed on the joist J using the floor board fixture A 1 having the rubber part 52 or the burr part 53, first, the sliding contact on the side where the rubber part 52 or the burr part 53 is formed. The floor plate B 1 is dropped diagonally downward so that the locking groove 4 of the floor plate B 1 is inserted into the portion 21, and the protruding corner portion 5 of the floor plate B 1 is brought into contact with the locking portion 20 and pressed. Next, the protruding corner portion 5 and the lower end surface 1b on the side inclined higher than the horizontal are brought into sliding contact with the sliding contact portion 21 of the adjacent floor plate fixture A 1 so that the lower surface 3 of the floor plate B 1 is placed on the joist member J. Just slide down until it touches. Note that when removing the fixed floor plate B 1 represents may be carried out in the procedure opposite to that described above. The external corner portion 5 and the lower end surface 1b is in sliding contact with the side of the sliding contact portion 21 and the engagement portion 20, since the rubber portion 52 or the burr 53 is not formed, attachment and detachment of the floor plate B 1 represents can be easily .

本発明の床板固定具Ａ1 によって、一枚単位で床板Ｂ1 を容易に交換可能となった結果、以下のような利点が挙げられる。前記床板Ｂ1 群のメンテナンスが時間的にも経済的にも効率良く実施できる。また、床板Ｂ1 の目地７から床板Ｂ1 群の下部空間に落下した硬貨や貴重品等の落下物を容易に拾得でき、前記下部空間に溜まったゴミ等を容易に除去できる。更に、前記下部空間を有効活用して、床板Ｂ1 群に付加価値をつけることが可能となる。例えば、床板Ｂ1 群の下部空間（例えば支持枠４１上）に照明装置を設置すれば、夜間に足元を照らせる床板Ｂ1 群になる。また、前記床板Ｂ1 群と地面Ｇとの間の空間に水道上下管を配管し、電線等を配線すれば、水を使用する場所、例えば、噴水、ジャグジーバス、ガーデニング可能な庭等に前記床板Ｂ1 群を採用することも可能となる。 As a result of the floor plate B 1 being easily replaceable in units of one sheet by the floor plate fixture A 1 of the present invention, the following advantages can be mentioned. Maintenance of the floor board B 1 group can be carried out efficiently in terms of time and economy. Also, coins or falling objects valuables dropped from joint 7 floorboards B 1 in the lower space of the floor panel B 1 group can be easily found item, can be easily removing dust or the like accumulated in the lower space. Furthermore, it is possible to add value to the floor board B 1 group by effectively utilizing the lower space. For example, if a lighting device is installed in the lower space of the floor board B 1 group (for example, on the support frame 41), the floor board B 1 group can illuminate the feet at night. Also, if a water pipe is piped in the space between the floor board B 1 group and the ground G and an electric wire is wired, the place is used in a place where water is used, for example, a fountain, a jacuzzi bath, a garden that can be gardened, etc. It is also possible to employ the floor board B 1 group.

FIGS. 12-A (A), (B) and FIGS. 12-B (C), (D) show the engagement between the floor plate fixtures A 2 to A 5 and the floor plate B 1 having the sliding contact portions 22 to 25, respectively. It is sectional drawing of a part. Here, in the floor plate fixtures A 2 to A 5 , the fixing portion 10 and the locking portion 20 in the portion below the sliding contact portions 22 to 25 have the same shape as the floor plate fixture A 1. Was attached. Further, the sliding contact portions 22 to 25 are common in that they have portions that protrude outward from the rising direction of the locking portion 20. First, as shown in FIG. 12-A (A), in the floor board fixture A 2 , the sliding contact portion 22 is bent outward so that the opening 8 is opposed, and the opening 8 side is widened. It has a U shape. 12A, the floor plate fixture A 2 is in a state in which the lower part of the floor plate B 1 is slightly in contact with or elastically contacted with the protruding corner portion 5 of the floor plate B 1. The floorboard B 1 is fixed on the joist J. Next, in the floor plate fixture A 3 , as shown in FIG. 12-A (B), the sliding contact portion 23 has a curved shape so that the cross section becomes a ring shape. In FIG. 12-A (b), the floor plate fixture A 3 causes the sliding contact portion 23 (the obliquely lower portion of the sliding contact portion 23) to contact or elastically contact the protruding corner portion 5 of the floor plate B 1 . In this state, the floor board B 1 is fixed on the joist J. Further, in the floor board fixture A 4 , as shown in FIG. 12-B (C), the sliding contact portion 24 has a substantially mountain-shaped cross section bent outward so that the opening 8 faces. Yes.

The floorboard B 1 is fixed on the joist J. Furthermore, in the floor plate fixture A 5 , as shown in FIG. 12-B (D), the sliding contact portion 25 is at the tip of the flat plate portion 25 a bent outward from the rising direction of the locking portion 20. It is the shape which has the curved part 25b bent toward the inner side. In FIG. 12-B (d), the floor board fixture A 5 is in a state of being in contact with or elastically contacting the most proximal portion of the sliding contact portion 25 with respect to the protruding corner portion 5 of the floor board B 1. B 1 is fixed on the joist J.

次に、図１３を用いて床板固定具Ａ6 について説明する。図１３（イ）は、床板固定具Ａ6 が床板Ｂ1 を係止している状態を正面から見た図であり、同（ロ）は、床板固定具Ａ6 の全体斜視図である。床板固定具Ａ1 ないしＡ5 において、一対の係止部２０は、固定部１０の幅方向の両端部から鈍角の起立角度θ0 で起立して対向形成されているが、以下に説明する形状の床板固定具Ａ6 を使用しても、前記床板固定具Ａ1 ないしＡ5 と同じように床板Ｂ1 を係止することができる。床板固定具Ａ6 は、ビス類６１を介して根太材Ｊ上に固定される固定部１０と、当該固定部１０の幅方向の両端部における長手方向に沿ってずれた位置から鋭角の起立角度θ3 で起立した一対の係止部３０からなっている。また、各係止部３０の先端部分には、床板Ｂ1 の着脱時に床板Ｂ1 の出隅部６及び下端面１ｂに摺接する摺接部３１が形成されている。このため、前記床板固定具Ａ6 の正面視では、一対の当該係止部３０は互いに交差した状態で、当該係止部３０先端の摺接部３１は外方に突出されている。前記摺接部３１の形状は、上記した摺接部２１ないし２５のいずれの形状でも良いが、図１３の摺接部３１は摺接部２１と同様の形状である。 Next, the floor board fixture A 6 will be described with reference to FIG. Figure 13 (b) is a view of a state in which the floor plate fixture A 6 is engaged the floor plate B 1 from the front, the (b) is an overall perspective view of a floor plate fixture A 6. In the floor plate fixtures A 1 to A 5 , the pair of locking portions 20 are formed to be opposed to each other while standing at an obtuse standing angle θ 0 from both ends in the width direction of the fixing portion 10. Even when the floor plate fixture A 6 is used, the floor plate B 1 can be locked in the same manner as the floor plate fixtures A 1 to A 5 . The floor plate fixture A 6 has an acute standing angle from a fixed portion 10 fixed on the joist J through screws 61 and positions shifted along the longitudinal direction at both ends in the width direction of the fixed portion 10. It consists of a pair of latching | locking part 30 which stood up at (theta) 3 . In addition, a sliding contact portion 31 is formed at the distal end portion of each locking portion 30 so as to be in sliding contact with the protruding corner portion 6 and the lower end surface 1b of the floor plate B 1 when the floor plate B 1 is attached and detached. For this reason, in the front view of the floor plate fixture A 6 , the sliding contact portion 31 at the tip of the locking portion 30 protrudes outward in a state where the pair of locking portions 30 intersect each other. The shape of the sliding contact portion 31 may be any of the sliding contact portions 21 to 25 described above, but the sliding contact portion 31 in FIG. 13 has the same shape as the sliding contact portion 21.

床板固定具Ａ6 を用いて、根太材Ｊ上に床板Ｂ1 を着脱する際は、上記の床板固定具Ａ1 による床板Ｂ1 の着脱方法と同じである。但し、係止部３０の起立角度θ3 が鋭角であるため、以下の点で前記床板固定具Ａ1 との相違がある。即ち、床板Ｂ1 が摺接部２１を介して前記床板固定具Ａ1 の係止部２０に作用すると、前記係止部２０の起立角度θは非変形状態の起立角度θ0 よりも小さくなるように弾性変形する。一方、床板固定具Ａ6 では、床板Ｂ1 が摺接部３１を介して係止部３０に作用すると、前記係止部３０の起立角度θは非変形状態の起立角度θ3 よりも大きくなるように弾性変形する。なお、図１３（イ）では、床板固定具Ａ6 は、床板Ｂ1 の出隅部５を摺接部３１のちょうど下端部に当接あるいは弾接させることによって、前記床板Ｂ1 を係止している。 When the floor board B 1 is attached to and detached from the joist J using the floor board fixture A 6 , the method is the same as the method of attaching and detaching the floor board B 1 with the floor board fixture A 1 described above. However, since the rising angle θ 3 of the locking portion 30 is an acute angle, there is a difference from the floor board fixture A 1 in the following points. That is, when the floor plate B 1 acts on the locking portion 20 of the floor plate fixture A 1 via the sliding contact portion 21, the standing angle θ of the locking portion 20 becomes smaller than the standing angle θ 0 in the non-deformed state. It is elastically deformed. On the other hand, in the floor plate fixture A 6 , when the floor plate B 1 acts on the locking portion 30 via the sliding contact portion 31, the rising angle θ of the locking portion 30 becomes larger than the rising angle θ 3 in the non-deformed state. It is elastically deformed. In FIG. 13 (a), floor fixtures A 6 are, by just contact the lower portion or the elastic contact of the sliding contact portion 31 of external corner portion 5 of the floor plate B 1, locking the floor plate B 1 is doing.

材質の弾性力を利用した床板固定具の別の例としては、図１４に示す床板固定具Ａ7 がある。図１４（イ）ないし（ハ）は、床板固定具Ａ7 に床板Ｂ1 を係止していく工程を正面から順番に見た図である。床板固定具Ａ7 は断面略Ｙ字状であって、根太材Ｊ上に固定される固定部７０と、該固定部７０の幅方向の中央から直上に起立した起立部８０と、該起立部８０の先端部に形成された一対の係止部９０とから成る。当該各係止部９０は、先端部に形成された上係止部９１、下端部に形成された下係止部９２、及び上係止部９１と下係止部９２を連結する本体係止部９３とから成り、各係止部９０は内側にわん曲された断面形状を有している。前記係止部９０の内側にわん曲された外周面が、床板固定具Ａ1 における摺接部２１と同様の作用効果を有している。前記各本体係止部９３の対向面には前記固定部７０の長手方向に沿って複数の突条９４が形成されている。なお、本実施例のビス類６１において、床板固定具Ａ1 ないしＡ6 を固定するビス類６１と用途は同様であるが、頭部の形状は、床板Ｂ1 と干渉しないようになべ頭状ではなく皿頭状となっている。 As another example of the floor plate fixture using the elastic force of the material, there is a floor plate fixture A 7 shown in FIG. FIGS. 14A to 14C are views in which the process of locking the floor board B 1 to the floor board fixture A 7 is viewed in order from the front. The floor plate fixture A 7 has a substantially Y-shaped cross section, and includes a fixing portion 70 fixed on the joist J, a standing portion 80 standing upright from the center in the width direction of the fixing portion 70, and the rising portion It consists of a pair of locking portions 90 formed at the tip of 80. Each of the locking portions 90 includes an upper locking portion 91 formed at the distal end portion, a lower locking portion 92 formed at the lower end portion, and a main body locking that connects the upper locking portion 91 and the lower locking portion 92. Each locking portion 90 has a cross-sectional shape bent inward. An outer peripheral surface which is curved inside of the locking portion 90 has the same effects as the sliding portion 21 of the floorboard fixture A 1. A plurality of protrusions 94 are formed along the longitudinal direction of the fixing portion 70 on the opposing surface of each main body locking portion 93. The screw 61 of this embodiment is used for the same purpose as the screw 61 for fixing the floor plate fixtures A 1 to A 6 , but the shape of the head is a pan head so as not to interfere with the floor plate B 1. It is not a dish-head.

床板固定具Ａ7 を用いて、床板Ｂ1 を根太材Ｊ上に固定する際は、以下の手順で行う。まず、床板Ｂ1 を水平方向に対して斜めに傾けながら、水平より低く傾いた側の端面１の係止溝４に、床板固定具Ａ7 の係止部９０が挿入されるように、床板Ｂ1 を前記係止部９０に向けて傾斜姿勢で落とし込む。前記係止溝４の上面４ａが前記係止部９０の上係止部９１に当接したら、この当接点９１ａを介して該上係止部９１を下方向に押圧し、係止部９０全体を弾性変形させる。弾性変形させた状態のまま、前記当接点９１ａ付近を中心に下方向に床板Ｂ1 を回動させることにより、前記当接点９１ａ側の出隅部５を下係止部９２の下側に入り込ませ、床板Ｂ1 の水平より高く傾いていた側においては、下端面１ｂと下面３との出隅部６を、隣接の床板固定具Ａ7 の係止部９０に摺接させる。前記出隅部６が前記係止部９０に摺接したら、更に下方へ押し込む。前記出隅部６は、係止部９０の内側にわん曲した外周面に摺接しながら下方に滑り込んでいく。前記出隅部６が前記係止部９０の下係止部９２下端まで到達した時点で、更に力を入れて下方に床板Ｂ1 を押し込むことにより、前記下係止部９２は下方向に弾性変形しながら床板Ｂ1 の下端面１ｂと摺接して出隅部５と摺接するまで、床板Ｂ1 は一気に押し込まれる。床板Ｂ1 の下面３が床板固定具Ａ7 の固定部７０上に当接するまで床板Ｂ1 が押し込まれると、それと同時に、下方に弾性変形していた前記下係止部９２には弾性復元力が上方に作用して、前記下係止部９２は上方に復元し、床板Ｂ1 の係止溝４の下面４ｂに当接或いは弾接する。この結果、床板Ｂ1 は床板固定具Ａ7 によって係止される。このとき、弾性変形されていた係止部９０の上係止部９１の弾性復元力に対して、下係止部９２によって係止溝４の下面４ｂが当接或いは弾接状態で係止されるので、前記上係止部９１が係止溝４の上面４ａと当接或いは弾接する場合でも、床板Ｂ1 は確実に床板固定具Ａ7 によって係止される。なお、床板Ｂ1 を着脱せずに根太材Ｊ上への固定状態を維持させておく場合には、床板固定具Ａ7 を弾性力のやや小さいアルミ材から成形し、一対の本体係止部９３の対向面によって形成される空間９５に、アンカーゴムＲを挿入して床板固定具Ａ7 の係止を強固にしてもよい。また、アンカーゴムＲの側面に、前記本体係止部９３の対向面に形成された突条９４に対応する溝を形成すれば、前記床板固定具Ａ7 の係止を更に強固に維持することができる。 When the floor board B 1 is fixed on the joist J using the floor board fixture A 7 , the following procedure is performed. First, the floor plate B 1 is inclined so as to be inclined with respect to the horizontal direction, so that the locking portion 90 of the floor plate fixture A 7 is inserted into the locking groove 4 of the end surface 1 on the side inclined below the horizontal. B 1 is dropped toward the locking portion 90 in an inclined posture. When the upper surface 4a of the locking groove 4 comes into contact with the upper locking part 91 of the locking part 90, the upper locking part 91 is pressed downward via the contact point 91a, and the entire locking part 90 is pressed. Is elastically deformed. The floor plate B 1 is rotated downward around the contact point 91 a while being elastically deformed, so that the protruding corner portion 5 on the contact point 91 a side enters the lower locking portion 92. On the side of the floor plate B 1 which is inclined higher than the horizontal, the protruding corner portion 6 of the lower end surface 1b and the lower surface 3 is brought into sliding contact with the locking portion 90 of the adjacent floor plate fixture A 7 . When the protruding corner portion 6 is in sliding contact with the locking portion 90, it is further pushed downward. The protruding corner portion 6 slides downward while being in sliding contact with the outer peripheral surface bent inside the locking portion 90. Elastic when the external corner portion 6 has reached the lower engaging portion 92 the lower end of the locking portion 90, by pushing the floorboard B 1 downward further focus, the lower engaging portion 92 downwards While being deformed, the floor board B 1 is pushed in at a stroke until it comes into sliding contact with the lower end surface 1 b of the floor board B 1 and comes into sliding contact with the protruding corner 5. When the lower surface 3 of the floorboard B 1 is pushed is floorboard B 1 until it abuts on the fixed portion 70 of the floor plate fixture A 7, at the same time, the elastic restoring force to the lower engaging portion 92 which has been elastically deformed downward There acts upward, the lower engaging portion 92 is restored upward to contact or elastic contact the lower surface 4b of the locking groove 4 of the floorboard B 1. As a result, the floor board B 1 is locked by the floor board fixture A 7 . At this time, with respect to the elastic restoring force of the upper locking portion 91 of the locking portion 90 that has been elastically deformed, the lower surface 4b of the locking groove 4 is locked in a contact or elastic contact state by the lower locking portion 92. Runode, the upper engaging portion 91 even when the contact top 4a and abutting or bullet of the locking groove 4, the floorboard B 1 represents locked securely by the floor plate fasteners a 7. In addition, when maintaining the fixed state on the joist J without removing the floor board B 1 , the floor board fixture A 7 is formed from an aluminum material having a little elastic force, and a pair of main body locking portions. The anchor rubber R may be inserted into the space 95 formed by the opposing surfaces 93 to strengthen the locking of the floor board fixture A 7 . Further, the side surface of the anchor rubber R, by forming a groove corresponding to the protrusion 94 formed on the opposite surface of the body hook 93, further possible to firmly maintain the engagement of the floor plate fixture A 7 Can do.

次に、図１７（イ）及び（ロ）を用いて床板固定具Ａ8 について説明する。図１７（イ）は、床板固定具Ａ8 が床板Ｂ2 を係止している状態を正面から見た断面図であり、同（ロ）は、床板固定具Ａ8 の全体斜視図である。床板固定具Ａ8 の構成は、床板固定具Ａ1 と比較して、係止部２０の起立角度θ及び係止部２０の先端部分が相違している。即ち、床板固定具Ａ1 における一対の係止部２０は、固定部１０の幅方向の両端部から鈍角の起立角度θ0 で起立して対向形成されているが、床板固定具Ａ8 は、一対の係止部２０のうち一方の係止部２０ａは、鈍角の起立角度θ0 で起立しているが、他方の係止部２０ｂは、固定部１０に対して直角の起立角度θ4 をなして起立している。また、前記係止部２０ａの先端部分には、床板固定具Ａ1 の摺接部２１と同一の摺接部２１が形成されていて、当該摺接部２１の形状は、前記係止部２０ａの起立方向よりも外方に突出し、わん曲された断面円弧状、又は近似円弧状である。一方、係止部２０ｂの先端部分には、当該係止部２０ｂの起立方向よりも外側に折曲された平板状の浮上り防止部２８が形成されている。 Next, a description will be given floor fixtures A 8 with reference to FIG. 17 (a) and (b). Figure 17 (b) is a sectional view of a state where the floorboard fixture A 8 is engaged the floor plate B 2 from the front, the (b) is a general perspective view of a floor plate fixture A 8 . The configuration of the floor board fixture A 8 is different from the floor board fixture A 1 in the rising angle θ of the locking portion 20 and the tip portion of the locking portion 20. That is, the pair of locking portions 20 of the floorboard fixture A 1 has been opposed formed by standing in an upright angle theta 0 obtuse angle from both ends in the width direction of the fixing portion 10, the floor plate fixture A 8 is One locking portion 20 a of the pair of locking portions 20 stands at an obtuse angle θ 0 , while the other locking portion 20 b has a vertical angle θ 4 perpendicular to the fixed portion 10. It stands up. Further, a sliding contact portion 21 that is the same as the sliding contact portion 21 of the floor plate fixture A 1 is formed at the distal end portion of the locking portion 20a. The shape of the sliding contact portion 21 is the locking portion 20a. It protrudes outward from the standing direction, and has a curved cross-section arc shape or approximate arc shape. On the other hand, a flat plate-like anti-lifting portion 28 that is bent outward from the standing direction of the locking portion 20b is formed at the tip of the locking portion 20b.

床板固定具Ａ8 を用いる際は、当該床板固定具Ａ8 に適した床板Ｂ2 を使用する。当該床板Ｂ2 は、床板固定具Ａ1 の際の床板Ｂ1 とは形状が異なる。即ち、床板Ｂ2 の両側の端面１に形成された係止溝４，４’の幅及び深さ方向の寸法がそれぞれ異なる。一点目は、前記床板Ｂ2 において、床板固定具Ａ8 の浮上り防止部２８が収納される側の係止溝４’は、摺接部２１が収納される側の係止溝４よりも幅は狭く、深さは深くなっている。二点目は、係止溝４が形成されている側の端面１は、上端面１ａに対して下端面１ｂが内側に入り込んだ段差状になっているが、係止溝４’が形成されている側の端面１’においては、上端面１ａ’と下端面１ｂ’は同一面上にあり、段差状にはなっていない。なお、前記係止溝４の上端面１ａに対する下端面１ｂの入り込み具合は、床板固定具Ａ1 の床板Ｂ1 に比べて大きく、上端面１ａがより一層張り出した形状となっている。 When the floor board fixture A 8 is used, a floor board B 2 suitable for the floor board fixture A 8 is used. The floor board B 2 is different in shape from the floor board B 1 in the case of the floor board fixture A 1 . In other words, the widths and the dimensions in the depth direction of the locking grooves 4 and 4 ′ formed on the end surfaces 1 on both sides of the floor board B 2 are different. The first point is that, in the floor board B 2 , the locking groove 4 ′ on the side where the lifting prevention part 28 of the floor board fixture A 8 is stored is more than the locking groove 4 on the side where the sliding contact part 21 is stored. The width is narrow and the depth is deep. Second, the end surface 1 on the side where the locking groove 4 is formed has a stepped shape in which the lower end surface 1b enters the inner side with respect to the upper end surface 1a, but the locking groove 4 ′ is formed. In the end surface 1 ′ on the side, the upper end surface 1a ′ and the lower end surface 1b ′ are on the same plane and are not stepped. Incidentally, enter condition of the lower end surface 1b for the upper end surface 1a of the locking groove 4 is larger than the floor plate B 1 of the floor plate fixtures A 1, the upper end face 1a has become more bulgy.

図１７に示されるように、床板Ｂ2 の上端面１ａ，１ａ’の垂直方向の長さ（厚さ）は異なっているが、下端面１ｂ，１ｂ’の垂直方向の長さ（厚さ）は同一で、出隅部５，５’の位置（高さ）が同一となっている。当該床板Ｂ2 の変形型として、例えば、床板Ｂ2 の上端面１ａ，１ａ’の前記長さが同一で、かつ下端面１ｂ，１ｂ’の前記長さ及び出隅部５，５’の高さが異なる構成の床板Ｂ2 ’が挙げられる（図示せず）。当該床板Ｂ2 ’を使用する場合には、出隅部５，５’の高さに対応させて、係止部２０ａ，２０ｂの各起立高さが異なる構成の床板固定具Ａ8 の変形型Ａ8 ’を用いると良い（図示せず）。 As shown in FIG. 17, the upper end surface 1a of the floor plate B 2, 1a 'vertical length of (thick), but are different, the lower end face 1b, 1b' vertical length of (thickness) Are the same, and the positions (heights) of the protruding corners 5 and 5 'are the same. As a modified form of the floorboard B 2, for example, the upper end surface 1a of the floor plate B 2, 1a 'the length of the same, and the lower end surface 1b, 1b' the length of and the external corner portions 5 and 5 'of the high There is a floor board B 2 ′ having a different configuration (not shown). When the floor plate B 2 ′ is used, a modified version of the floor plate fixture A 8 having a structure in which the standing heights of the locking portions 20a and 20b are different in accordance with the heights of the protruding corner portions 5 and 5 ′. A 8 'may be used (not shown).

床板固定具Ａ8 を用いて、根太材Ｊ上に床板Ｂ2 を着脱する際は、上記の床板固定具Ａ1 による床板Ｂ1 の着脱方法と類似である。但し、床板固定具Ａ8 の係止部２０’ｂは直角の起立角度θ4 で起立し、その先端部分に浮上り防止部２８を有するために、前記床板固定具Ａ1 との間には新規に床板Ｂ1 を根太材Ｊ上に取り付けて敷設していく工程に相違点がある。即ち、床板固定具Ａ1 を用いて新規に床板Ｂ1 を敷設していく場合には、前記床板固定具Ａ1 を予め根太材Ｊに固定しておき、後から床板Ｂ1 を取り付けていくことができたが、床板固定具Ａ8 を用いる場合には、床板固定具Ａ8 の根太材Ｊ上への固定と床板Ｂ2 の取り付けを交互に行って床板Ｂ2 を敷設していく必要がある。以下、図１８（イ）ないし（ハ）を用いて、床板Ｂ2 の敷設工程を説明する。図１８（イ）ないし（ハ）は、床板固定具Ａ8 に床板Ｂ2 を係止していく工程を正面から順番に見た図である。床板Ｂ2 を一枚ずつ順番に根太材Ｊ上の所定場所から新規に敷設していく場合には、まず、床板Ｂ2 の目地幅Ｗ1 及び床板幅Ｗ0 を考慮してピッチＰ1 を決め、根太材Ｊ上にピッチＰ1 ごとに目印等をつけておく。次に、図１８（イ）に示すように、最初の床板固定具Ａ8 を根太材Ｊ上に配置する際は、一対の係止部２０ａ，２０ｂのうち係止部２０ａ側が床板Ｂ2 の敷設方向を向くように敷設開始場所に配置する。そして、前記最初の床板固定具Ａ8 をビス類６１で根太材Ｊ上に固定する。次に、前記床板固定具Ａ8 の隣、即ち係止部２０ａに出隅部５が当接するようにして一枚目の床板Ｂ2 を載置する。図１８（ロ）に示すように、二個目の床板固定具Ａ8 を前記床板Ｂ2 の隣に置き、当該床板固定具Ａ8 の浮上り防止部２８を前記床板Ｂ2 の係止溝４’に収納させる。前記床板Ｂ2 の出隅部５を、最初に固定した床板固定具Ａ8 の係止部２０ａに当接させた状態で、前記床板Ｂ2 を根太材Ｊの長手方向Ｓに沿ってスライドさせて、前記係止部２０ａをその起立角度θが僅かに小さくなるように押圧する。前記係止部２０ａを押圧した状態のまま、二個目の床板固定具Ａ8 の位置をピッチＰ1 の前記目印に合わせる。ドリルビス等を用いて根太材Ｊを穿孔すると同時にビス類６１で前記床板固定具Ａ8 を固定する。このとき、最初に取り付けられた床板固定具Ａ8 において、押圧されていた係止部２０ａは弾性変形し、前記床板Ｂ2 の出隅部５を弾接状態で係止させる。また、前記係止部２０ａの起立角度はθ1 となっていて、係止状態の起立角度θ1 は、非変形状態の起立角度θ0 よりも小さい。一方、二個目に取り付けられた床板固定具Ａ8 において、係止部２０ｂの起立角度θ4 は直角であるため、前記係止部２０ｂは全面に亘り前記床板Ｂ2 の下端面１ｂ’と接している。前記係止部２０ｂの先端部分の浮上り防止部２８は、前記床板Ｂ1 の係止溝４’に収納されており、前記浮上り防止部２８の下端部２８ｂは前記床板Ｂ2 の出隅部５’を係止している。従って、前記床板Ｂ2 は、最初の床板固定具Ａ8 の係止部２０ａによって出隅部５を、二個目の床板固定具Ａ8 の係止部２０ｂによって出隅部５’を係止されることで、根太材Ｊ上に固定されている。なお、このときの二個目の床板固定具Ａ8 における前記浮上り防止部２８の先端部分２８ａは、係止溝４’の上面４ａ’に当接しているか、又は前記上面４ａ’との間に極めて僅かな隙間があるのみである。次に、図１８（ハ）に示すように、二枚目以降の床板Ｂ2 を根太材Ｊ上に敷設していく場合には、上記工程を繰り返し、床板固定具Ａ8 と床板Ｂ2 とを交互に根太材Ｊに取り付けていけばよい。 When the floor board B 2 is attached to and detached from the joist J using the floor board fixture A 8 , it is similar to the method of attaching and detaching the floor board B 1 with the floor board fixture A 1 described above. However, the locking portion 20′b of the floor plate fixture A 8 stands at a right angle θ 4 and has a lift prevention portion 28 at the tip thereof, so that it is not between the floor plate fixture A 1. There is a difference in the process of newly installing and laying the floor board B 1 on the joist J. In other words, when going laid floorboard B 1 de novo using floorboards fixtures A 1 is previously fixed to the floor plate fixture A 1 in advance joist material J, we attach the floorboard B 1 later it was possible, but in the case of using the floor fixture a 8 is required to the fixing and mounting floorboard B 2 onto joists material J floorboards fixture a 8 alternately performed gradually laid floorboard B 2 There is. Hereinafter, the laying process of the floor board B 2 will be described with reference to FIGS. It Figure 18 (a) to (c) is a view in sequence the steps going locking the floorboard B 2 in floor fixtures A 8 from the front. When newly laying floor boards B 2 one by one from a predetermined location on the joist J, first, the pitch P 1 is set in consideration of the joint width W 1 and floor board width W 0 of the floor board B 2. Decide and place a mark or the like on the joist J for each pitch P 1 . Next, as shown in FIG. 18 (b), when arranging the first floor fixtures A 8 on joists member J has a pair of engaging portions 20a, the locking portion 20a side of 20b of the floorboard B 2 Place it at the laying start location so that it faces the laying direction. Then, the first floor board fixture A 8 is fixed onto the joist J with screws 61. Next, the first floor plate B 2 is placed next to the floor plate fixture A 8 , that is, with the protruding corner portion 5 coming into contact with the locking portion 20 a. As shown in FIG. 18 (b), the two first floorboards fixture A 8 placed next to the floor plate B 2, the locking groove to uplift prevention portion 28 of the floor plate fixture A 8 of the floorboard B 2 Store in 4 '. The external corner portion 5 of the floor plate B 2, being in contact with the engaging portion 20a of the floor plate fixture A 8 which initially fixed, by sliding along the floor plate B 2 in the longitudinal direction S of the joist material J Then, the locking portion 20a is pressed so that the standing angle θ is slightly reduced. The position of the second floor board fixture A 8 is adjusted to the mark of the pitch P 1 while the locking portion 20a is pressed. The floor plank J is drilled using a drill screw or the like, and at the same time, the floor plate fixture A 8 is fixed with screws 61. In this case, the floorboards fixture A 8 attached to the first locking portion 20a that has been pressed is elastically deformed, engaging the external corner portion 5 of the floor plate B 2 in elastic contact state. Also, standing angle of the locking portion 20a is not a theta 1, upright angle theta 1 of the locking state is smaller than the upstanding angle theta 0 undeformed state. On the other hand, in the floorboard fixture A 8 attached to the two eyes, since the standing angle theta 4 of the locking portion 20b is perpendicular, the locking portion 20b and the lower end surface 1b of the floor plate B 2 over the entire surface ' It touches. The locking portion 20b of the tip portion of the uplift prevention unit 28, the floor plate B are housed in one of the locking grooves 4 ', the lower end portion 28b of the uplift prevention unit 28 external corner of the floor plate B 2 The part 5 'is locked. Therefore, the floor plate B 2 is an external corner portion 5 by the locking portion 20a of the first floorboard fixture A 8, engaging an external corner portion 5 'by the locking portion 20b of the two eyes of the floorboard fixture A 8 As a result, it is fixed on the joist J. Incidentally, the tip portion 28a of the uplift prevention unit 28 in the two eyes of the floorboard fixture A 8 at this time, between the locking groove 4 in or in contact with 'the upper surface 4a of' or the upper surface 4a ' There are only very small gaps. Next, as shown in FIG. 18 (c), when the second and subsequent floor boards B 2 are laid on the joist J, the above steps are repeated, and the floor board fixture A 8 and the floor board B 2 Can be attached to the joists J alternately.

図１９（イ），（ロ）を用いて、床板固定具Ａ1 に対する床板固定具Ａ8 の優れた点について説明する。図１９（イ）は、床板固定具Ａ1 が床板Ｂ1 を係止している状態を正面から見た図である。同（ロ）は、床板固定具Ａ8 が床板Ｂ2 を係止している状態を正面から見た図である。図１９（イ）に示すように、床板固定具Ａ1 を用いて床板Ｂ1 を根太材Ｊ上に固定した場合には、前記床板Ｂ1 の両出隅部５と共に、前記床板Ｂ1 に隣接する各床板固定具Ａ1 の係止部２０に弾接されることによって、前記床板Ｂ1 は係止されている。このため、例えば長時間の使用等により、床板Ｂ1 が長手方向Ｔに沿って反り上がり、床板固定具Ａ1 によって係止されている部分が浮き上がってしまうと、前記床板固定具Ａ1 の係止部２０は、弾性変形して起立角度θを小さくして倒れるように弾性変形してしまうので、前記床板Ｂ1 の係止部分の浮き上がりを防止することができない可能性がある。なお、図１９（イ）において、浮き上がった床板Ｂ1 は二点鎖線で示した。一方、図１９（ロ）に示すように、床板固定具Ａ8 を用いて床板Ｂ2 を根太材Ｊ上に固定した場合には、床板Ｂ2 の係止部分の浮上りを防止できる。以下に理由を示す。一点目は、前記床板固定具Ａ8 の係止部２０ｂの起立角度θ4 は直角であるために、前記係止部２０ｂは全面に亘って床板Ｂ2 の下端面１ｂ’と接しており、前記係止部２０ｂが押圧されても、弾性変形することは殆どない点である。二点目は、床板Ｂ2 の係止溝４’には、床板固定具Ａ8 の浮上り防止部２８が完全に収納されていて、その先端部分２８ａは、係止溝４’の上面４ａ’とほぼ当接状態にある点である。三点目は、床板Ｂ2 の出隅部５’が前記浮上り防止部２８の下端部２８ｂによって当接状態で係止されている点である。従って、床板Ｂ2 が長手方向Ｔに反り上がり、床板固定具Ａ8 との係止部分が浮き上がろうとして各係止部２０ａ，２０ｂを押圧しても、床板固定具Ａ8 の係止部２０ｂは殆ど弾性変形せず、また、浮上り防止部２８は、その先端部分２８ａを係止溝４’の上面４ａ’にほぼ当接した状態で収納されていて、かつその下端部２８ｂで出隅部５’を係止しているので、床板Ｂ2 が浮き上ることはない。 Figure 19 (b), with (b), will be described better in terms of floor fixtures A 8 against the floorboard fixture A 1. Figure 19 (b) is a view of a state in which the floor plate fixture A 1 is engaged the floor plate B 1 from the front. The figure (b) is a view of the state in which the floor board fixture A 8 is locking the floor board B 2 as seen from the front. As shown in FIG. 19 (a), when the floor board B 1 is fixed onto the joist J using the floor board fixture A 1 , the floor board B 1 together with the projecting corners 5 of the floor board B 1 is attached to the floor board B 1 . The floor plate B 1 is locked by being elastically contacted with the locking portion 20 of each adjacent floor plate fixture A 1 . For this reason, for example, if the floor board B 1 is warped along the longitudinal direction T due to long-time use or the like, and the portion locked by the floor board fixture A 1 is lifted, the engagement of the floor board fixture A 1 will be described. Since the stopper 20 is elastically deformed and elastically deforms so as to fall with the rising angle θ being reduced, it may not be possible to prevent the locking portion of the floor board B 1 from being lifted. In FIG. 19A, the raised floor board B 1 is indicated by a two-dot chain line. On the other hand, as shown in FIG. 19 (b), when the floor plate B 2 with floor fixtures A 8 immobilized on joist material J can prevent the Ri floating locking portion of the floorboard B 2. The reason is shown below. The first point is that the upright angle θ 4 of the locking portion 20b of the floor plate fixture A 8 is a right angle, so that the locking portion 20b is in contact with the lower end surface 1b ′ of the floor plate B 2 over the entire surface. Even when the locking portion 20b is pressed, it is hardly deformed elastically. The second point is that the lifting prevention portion 28 of the floor plate fixture A 8 is completely accommodated in the locking groove 4 ′ of the floor plate B 2 , and the tip portion 28 a is the upper surface 4 a of the locking groove 4 ′. The point is almost in contact with '. The third point is that the protruding corner portion 5 ′ of the floor board B 2 is locked in contact with the lower end portion 28 b of the lifting prevention portion 28. Therefore, even if the floor plate B 2 is warped in the longitudinal direction T and the locking portion 20a, 20b is pressed while the locking portion with the floor plate fixing tool A 8 is lifted, the locking of the floor plate fixing tool A 8 is performed. The portion 20b is hardly elastically deformed, and the anti-lifting portion 28 is housed with its tip end portion 28a substantially in contact with the upper surface 4a ′ of the locking groove 4 ′ and at its lower end portion 28b. since locks the external corner portions 5 ', never floorboard B 2 is climbing lifting.

次に、図２０（イ），（ロ）を用いて、上記の工程で根太材Ｊ上に敷設された床板Ｂ2 群から、任意の一枚の床板Ｂ2 を脱着する工程について説明する。図２０（イ），（ロ）は、根太材Ｊ上に敷設された床板Ｂ2 群から一枚の床板Ｂ2 を取り外す工程を正面から順番に見た図である。当該工程は、床板固定具Ａ1 を用いて敷設された床板Ｂ1 群から、任意の一枚の床板Ｂ1 を脱着する工程とほぼ同一であるが、異なる点は、床板Ｂ2 を持ち上げる側が決まっている点である。即ち、隣接の床板固定具Ａ1 に両端部を係止されている床板Ｂ1 の場合は、床板Ｂ1 のどちらの端部を持ち上げても取り外すことは可能であるが、隣接する床板固定具Ａ8 に両端部を係止されている床板Ｂ2 の場合は、一方の端部では前記床板固定具Ａ8 の浮上り防止部２８を係止溝４’内に深く収納させているので、他方側、即ち前記床板固定具Ａ8 に隣接の床板固定具Ａ8 の係止部２０ａによって係止されている側の端部を持ち上げる必要がある。以下に、床板Ｂ2 の取付け手順を示す。まず、図２０（イ）に示すように、床板固定具Ａ8 の係止部２０ａに係止されている側の端部を持つ。次に、当該端部とは反対側で前記浮上り防止部２８に当接している出隅部５’を中心として、床板Ｂ2 を回動させるように前記端部を持ち上げる。そのまま前記端部を持ち上げていくと、出隅部５が摺接部２１に当接し、前記係止部２０ａは起立角度θを小さくする方向に弾性変形するので、前記摺接部２１は係止溝４から外れる。図２０（ロ）に示すように、持ち上げられた側の床板Ｂ2 の端部が完全に床板固定具Ａ8 から外れたら、前記床板Ｂ2 を斜め上方にスライドさせて、回動中心となっていた側の係止溝４’から前記浮上り防止部２８を抜き出す。最後に、床板Ｂ2 をその傾斜方向に沿って引き上げて、床板Ｂ2 を根太材Ｊから取り外す。なお、取り外した床板Ｂ2 を元の位置に戻して再び取り付けるには、上記手順の逆の手順を行えばよい。従って、床板固定具Ａ8 を用いて床板Ｂ2 を一枚ずつ脱着することは問題なく実施することが可能である。 Next, FIG. 20 (b), with (b), the floor plate B 2 group laid on joists material J in the above process, steps that desorbing any one piece of the floorboard B 2. Figure 20 (a), (b) is a view in sequence the steps of removing a piece of floorboard B 2 from the laid floorboard B 2 group on joists material J from the front. The process is from floor plate B 1 group laid with floorboards fixtures A 1, is substantially identical to the step of detaching any one piece of the floorboard B 1, is different from, the side to lift the floorboard B 2 It is a fixed point. That is, in the case of floor plate B 1 which is locked to both ends of the floor plate fixture A 1 of the adjacent, although it is possible to remove even lift either end of the floor plate B 1, adjacent floor plate fixture for floorboard B 2 which is locked to both ends of the a 8, since at one end and is deeply housed uplift prevention portion 28 of the floor plate fixture a 8 in the locking groove 4 ', the other side, i.e., it is necessary to lift the end of the side is locked by the locking portion 20a of the adjacent floor plate fixture a 8 floorboard fixture a 8. Hereinafter, a mounting procedure of the floorboard B 2. First, as shown in FIG. 20 (b), with the end on the side which is engaged with the engaging portion 20a of the floor plate fixture A 8. Next, the end portion is lifted so that the floor plate B 2 is rotated around the protruding corner portion 5 ′ that is in contact with the floating prevention portion 28 on the side opposite to the end portion. When the end portion is lifted as it is, the protruding corner portion 5 comes into contact with the sliding contact portion 21 and the locking portion 20a is elastically deformed in the direction of decreasing the rising angle θ, so that the sliding contact portion 21 is locked. Detach from the groove 4. As shown in FIG. 20 (b), when the end of the raised floor board B 2 is completely disengaged from the floor board fixture A 8 , the floor board B 2 is slid obliquely upward to become the center of rotation. The lifting prevention portion 28 is extracted from the locking groove 4 ′ on the side that has been left. Finally, the floor board B 2 is pulled up along the inclination direction, and the floor board B 2 is removed from the joist J. Note that the reattached back the removed floor plate B 2 to the original position, may be performed reverse order of the above procedure. Therefore, it is possible to carry out the removal of the floor boards B 2 one by one using the floor board fixture A 8 without any problem.

次に、図２１（イ），（ロ）を用いて、床板固定具Ａ9 について説明する。図２１（イ）は、床板固定具Ａ9 が床板Ｂ3 を係止している状態における断面図であり、同（ロ）は、床板固定具Ａ9 の全体斜視図である。なお、図２１（イ）は、同（ロ）のＸ−Ｘ線断面図である。まず、床板固定具Ａ9 の構成について説明する。床板固定具Ａ9 は、床板固定具Ａ1 と同様な弾性変形可能なバネ鋼で成形され、根太材Ｊ状にビス類６１で固定される固定部１０と、当該固定部１０の幅方向の両端から鈍角の起立角度θ0 で起立して対向形成された長さの異なる一対の係止部２０’ａ，２０’ｂからなる。長さの短い側の係止部２０’ａは、長い側の係止部２０’ｂの長手方向の中央部にのみ形成されていて、前記短い側の係止部２０’ａが起立している側の前記固定部１０の端部において、当該係止部２０’ａが形成されていない部分には、床板固定具Ａ9 の幅方向、即ち根太材Ｊの長手方向Ｓに延設された延設固定部１０ａが形成されている。当該延設固定部１０ａにもビス孔１１が形成されている。各係止部２０’ａ，２０’ｂの先端部分には、床板固定具Ａ1 と同一形状の摺接部２１ａ，２１ｂがそれぞれ形成されていて、当該摺接部２１ａ，２１ｂの形状は、前記係止部２０’ａ，２０’ｂの起立方向よりも外方に突出して、わん曲された断面円弧状、又は近似円弧状である。即ち、床板固定具Ａ9 は、床板固定具Ａ1 と比べると、一対の係止部２０’ａ，２０’ｂの長手方向の長さがそれぞれ異なる点、及び長さの短い係止部２０’ａが起立している側の固定部１０の端部には延設固定部１０ａが延設されている点で相違しているが、他の構成は同一である。 Next, the floor board fixture A 9 will be described with reference to FIGS. Figure 21 (b) is a sectional view of the state where the floorboard fixture A 9 is locked floorboards B 3, the (b) is an overall perspective view of a floor plate fixture A 9. FIG. 21A is a sectional view taken along line XX of FIG. First, the configuration of the floor plate fixture A 9. The floor plate fixture A 9 is formed of an elastically deformable spring steel similar to the floor plate fixture A 1, and a fixed portion 10 fixed with screws 61 in a joist J shape, and a width direction of the fixed portion 10. It consists of a pair of engaging portions 20′a and 20′b of different lengths that are formed to face each other at an obtuse standing angle θ 0 . The locking portion 20′a on the short side is formed only at the longitudinal center of the locking portion 20′b on the long side, and the locking portion 20′a on the short side stands up. At the end portion of the fixing portion 10 on the side where it is located, the portion where the locking portion 20 ′ a is not formed is extended in the width direction of the floor plate fixture A 9 , that is, in the longitudinal direction S of the joist J. An extending fixing portion 10a is formed. Screw holes 11 are also formed in the extended fixing portion 10a. Each locking portion 20'a, the tip portion of the 20 'b, floor fixtures A 1 and the same shape of the sliding contact portion 21a, and 21b is not formed respectively, the sliding contact portion 21a, the shape of 21b is The engaging portions 20′a and 20′b protrude outward from the standing direction and have a curved cross-sectional arc shape or an approximate arc shape. That is, the floor plate fixture A 9 is different from the floor plate fixture A 1 in that the lengths of the pair of locking portions 20′a and 20′b are different from each other in the longitudinal direction, and the locking portion 20 having a short length. Although it is different in that the extended fixed portion 10a is extended at the end of the fixed portion 10 on the side where 'a stands, the other configuration is the same.

床板固定具Ａ9 を用いる際は、当該床板固定具Ａ9 に適した床板Ｂ3 を使用する。当該床板Ｂ3 の形状は、床板固定具Ａ1 ないしＡ5 用の床板Ｂ1 に、延設固定部１０ａを収容するための収容溝９が長手方向に沿って形成されたものである。前記収容溝９が形成されている以外の構成は、床板Ｂ3 と床板Ｂ1 は同一である。 When the floor board fixture A 9 is used, a floor board B 3 suitable for the floor board fixture A 9 is used. The shape of the floor board B 3 is such that an accommodation groove 9 for accommodating the extension fixing portion 10a is formed along the longitudinal direction in the floor board B 1 for the floor board fixtures A 1 to A 5 . The floor board B 3 and the floor board B 1 are the same except for the structure in which the housing groove 9 is formed.

床板固定具Ａ9 を根太材Ｊ上に固定する場合には、前記固定部１０に延設固定部１０ａが形成されたことにより、当該延設固定部１０ａにビス類６１を挿通して前記床板固定具Ａ9 を根太材Ｊ上に固定できる。また、固定部１０に形成されるビス孔１１を、係止部２０’ａ，２０’ｂに挟まれた部分ではなく、前記係止部３０’ａの形成されていない部分に設けることにより、床板固定具Ａ1 のように、一対の係止部２０に挟まれた固定部１０に形成されたビス孔１１にビス類６１を挿通するよりも、ビス類６１を挿通しやすく、また、より強固に床板固定具Ａ9 を根太材Ｊ上に固定できる。 In the case of fixing the floor plate fixture A 9 on the joist J, since the extended fixing portion 10a is formed in the fixing portion 10, the screws 61 are inserted into the extended fixing portion 10a and the floor plate is fixed. Fixing tool A 9 can be fixed on joist J. In addition, by providing the screw hole 11 formed in the fixing portion 10 not in the portion sandwiched between the locking portions 20′a and 20′b but in the portion where the locking portion 30′a is not formed, The screw 61 is easier to insert than the screw 61 inserted into the screw hole 11 formed in the fixing portion 10 sandwiched between the pair of locking portions 20 like the floor plate fixture A 1 , and more The floor plate fixture A 9 can be firmly fixed on the joist J.

新規に床板Ｂ3 を根太材Ｊ上に敷設していく場合には、床板固定具Ａ1 と同様に、予め根太材Ｊ上に床板固定具Ａ9 を所定間隔で固定しておき、後から床板Ｂ3 を取り付けていくことは可能であるが、床板固定具Ａ9 の固定と床板Ｂ3 の取り付けを交互に行うと、敷設作業を容易にかつ効率良く行うことができる。図２２（イ）ないし（ハ）を用いて、床板固定具Ａ9 を用いた床板Ｂ3 の敷設工程について説明する。図２２（イ）ないし（ハ）は、床板固定具Ａ9 に床板Ｂ3 を係止していく工程を正面から順番に見た図である。まず、図２２（イ）に示すように、床板固定具Ａ9 を敷設方向の前方に延設固定部１０ａが向くように配置し、根太材Ｊ上に最初の床板固定具Ａ9 を固定する。次に、当該床板固定具Ａ9 の隣に最初の床板Ｂ3 を置き、当該床板Ｂ3 の収容溝９に前記床板固定具Ａ9 の延設固定部１０ａを収容するように根太材Ｊの長手方向Ｓに沿ってスライドさせて、前記床板Ｂ3 の出隅部５が前記床板固定具Ａ9 の係止部２０’ａに当接か又は僅かに弾接状態となるところを前記床板Ｂ3 の固定位置とする。図２２（ロ）に示すように、前記床板Ｂ3 を基準として、その隣に２個目の床板固定具Ａ9 を置き、前記床板Ｂ3 が動かないように押さえながら、当該床板固定具Ａ9 が前記床板Ｂ3 を当接又は弾接状態で係止するように前記床板固定具Ａ9 の位置を合わせる。その位置で２個目の床板固定具Ａ9 をビス類６１で固定する。次に、２枚目の床板Ｂ3 を最初の床板Ｂ3 と同様にして配置し、上記工程を繰り返して床板Ｂ3 を根太材Ｊ上に敷設していく。従って、床板固定具Ａ9 の固定位置は床板Ｂ3 の幅を基準に合わせればよく、前記床板固定具Ａ9 が床板Ｂ3 を当接又は弾接状態で係止するように床板Ｂ3 を押さえながら、床板固定具Ａ9 と床板Ｂ3 を交互に並置して根太材Ｊ上に取り付けていけばよいので、容易で効率良い作業の繰り返しで床板Ｂ3 を敷設することが可能である。 When the floor board B 3 is newly laid on the joist board J, the floor board fixing tool A 9 is fixed on the joist board J at a predetermined interval in the same manner as the floor board fixing tool A 1, and later. While it is possible that we attach the floor panel B 3, when performing the mounting of the fixed and floor plate B 3 of the floorboard fixture a 9 alternately, can be carried out easily and efficiently laying work. A process of laying the floor board B 3 using the floor board fixture A 9 will be described with reference to FIGS. It Figure 22 (a) to (c) is a view in sequence the steps going locking the floor panel B 3 to the floorboard fixture A 9 from the front. First, as shown in FIG. 22 (b), arranged to the floor fixture A 9 in front of the laying direction to which extend the fixing portion 10a, for fixing the first floor fixture A 9 on joists material J . Next, place the first floor panel B 3 next to the floor plate fixture A 9, the joists material J to accommodate the extended fixing portion 10a of the floor plate fixture A 9 in the housing groove 9 of the floor panel B 3 slide along the longitudinal direction S, said place where external corner portion 5 of the floor panel B 3 is abutting or slightly elastic contact state with the engaging portion 20'a of the floor plate fixture a 9 floorboard B 3 fixed position. As shown in FIG. 22 (b), with the floor board B 3 as a reference, a second floor board fixture A 9 is placed next to the floor board B 3 and pressed so that the floor board B 3 does not move. The floor plate fixture A 9 is aligned so that 9 locks the floor plate B 3 in a contact or elastic contact state. At that position, the second floor plate fixture A 9 is fixed with screws 61. Next, a second sheet of floorboards B 3 are arranged in the same manner as the first floor panel B 3, continue to lay a floor panel B 3 on joists material J repeat the above steps. Therefore, the fixed position of the floor plate fixture A 9 may, combined, based on the width of the floor panel B 3, the floor panel B 3 such that the floor plate fixture A 9 is locked floorboards B 3 in contact with or elastic contact state pressing while, since it should be juxtaposed with the floor plate fixture a 9 and floor plate B 3 alternately mounted on joists material J, it is possible to lay floor B 3 in an easy and repetition of efficient work.

上記したように、床板固定具Ａ9 は、一対の係止部２０’ａ，２０’ｂの長手方向の長さが異なる点、及び固定部１０に延設固定部１０ａが延設されている点で床板固定具Ａ1 と相違しているが、他の構成は同一であるため、床板固定具Ａ9 を用いて根太材Ｊ上に敷設された床板Ｂ3 群から任意の一枚を脱着する方法は、床板固定具Ａ1 を用いて敷設された床板Ｂ1 群から任意の一枚を脱着する方法と同一である。ただし、前記係止部２０’ａと２０’ｂの長手方向の長さは異なっているため、長さの短い係止部２０’ａの方が、より小さい押圧力で弾性変形させることが可能である。このため、一枚の床板Ｂ3 を取り外す際は、当該床板Ｂ3 の両側の端部のうち、係止部２０’ａで出隅部５を係止されている側の端部を持ち上げた方が取り外し易い。また、再び床板Ｂ3 を戻して取り付ける際は、取り外したときと逆の手順をたどればよい。 As described above, in the floor plate fixture A 9 , the length of the pair of locking portions 20 ′ a and 20 ′ b in the longitudinal direction is different, and the extending fixing portion 10 a is extended to the fixing portion 10. Although different from the floorboard fixture a 1 at point desorption, since other configurations are the same, any one from the laid floor panel B 3 groups on joists material J using floorboards fixture a 9 The method of doing is the same as the method of detaching any one piece from the floor board B 1 group laid by using the floor board fixture A 1 . However, since the lengths of the locking portions 20'a and 20'b in the longitudinal direction are different, the locking portion 20'a having a shorter length can be elastically deformed with a smaller pressing force. It is. Therefore, when removing the single floor panel B 3, of the end portions on both sides of the floor panel B 3, lifted end side being engaged with external corner portion 5 at the locking portion 20'a Is easier to remove. Also, when mounting again return the floor panel B 3, it may be traced to the reverse of the removal procedure.

次に、図２３（イ），（ロ）を用いて床板固定具Ａ10について説明する。図２３（イ）は、床板固定具Ａ10が床板Ｂ4 を係止している状態における断面図であり、同（ロ）は、床板固定具Ａ10の全体斜視図である。なお、図２３（イ）は、同（ロ）のＸ−Ｘ線断面図である。床板固定具Ａ10は、床板固定具Ａ9 における摺接部２１ｂが浮上り防止部２８に置き換わった構成である。即ち、床板固定具Ａ10の固定部１０には延設固定部１０ａが形成され、長さの異なる一対の係止部２０’ａ，２０’ｂのうち、長さの長い側の係止部２０’ｂの先端部には浮上り防止部２８が形成されている。床板固定具Ａ10を用いる際に使用される床板Ｂ4 は、床板固定具Ａ8 に適した床板Ｂ2 に延設固定部１０ａを収容可能な収容溝９を長手方向に沿って形成されているものである。床板固定具Ａ10及び床板Ｂ4 を用いることによって、以下に示すように、床板固定具Ａ8 と床板固定具Ａ9 の効果が同時に奏される。即ち、まず、床板固定具Ａ8 と同様に、床板Ｂ4 が長手方向に反り上がっても、床板固定具Ａ10から床板Ｂ4 が浮き上って外れることはない。次に、床板固定具Ａ10を用いて床板Ｂ4 を根太材Ｊ上に敷設していく際には、浮上り防止部２８の形状のために床板固定具Ａ10の固定と床板Ｂ4 の取り付けを順番に行う必要があるが、延設固定部１０ａが形成されているので、容易に床板固定具Ａ10の位置決めをしながら効率良く順番に床板Ｂ4 を敷設していくことが可能である。また、根太材Ｊ上に敷設した床板Ｂ4 群から任意の一枚を脱着できるのは明らかであり、更に、前記床板Ｂ4 を取り外す際は、長さの短い側の係止部２０’ａに係止されている側の端部を持って床板Ｂ4 を回動させるように持ち上げれば、長さの短い側の係止部２０’ａは長い側の係止部２０’ｂよりも小さな力で弾性変形するので、床板固定具Ａ8 と比較して持ち上げ易く、取り外し易い。 Next, the floor board fixture A 10 will be described with reference to FIGS. FIG. 23A is a cross-sectional view in a state where the floor board fixture A 10 is locking the floor board B 4 , and FIG. 23B is an overall perspective view of the floor board fixture A 10 . FIG. 23A is a cross-sectional view taken along line XX of FIG. The floor plate fixture A 10 has a configuration in which the sliding contact portion 21b in the floor plate fixture A 9 is replaced with a lift prevention portion 28. In other words, the fixing portion 10 of the floor plate fixture A 10 is formed extending fixing portion 10a, different pair of locking portions 20'a lengths, of the 20 'b, the long side of the length locking portion An anti-lifting portion 28 is formed at the tip of 20'b. The floor board B 4 used when the floor board fixing tool A 10 is used is formed with a receiving groove 9 along the longitudinal direction capable of accommodating the extended fixing part 10a on the floor board B 2 suitable for the floor board fixing tool A 8. It is what. By using the floor board fixture A 10 and the floor board B 4 , the effects of the floor board fixture A 8 and the floor board fixture A 9 are produced simultaneously as shown below. That is, first, similarly to the floor plate fixture A 8, floor plate B 4 is also warped in the longitudinal direction, it does not depart up floorboards B 4 floats from the floor fixture A 10. Next, when using a floor plate fasteners A 10 continue to laying floor plate B 4 on joists material J is fixed and the floor plate B 4 floorboard fixture A 10 for the shape of the uplift prevention section 28 it is necessary to perform the installation in order, since the extended fixing portion 10a is formed, can continue to laying floor plate B 4 efficiently turn while easily positioning the floorboards fixture a 10 is there. Further, it is clear that any one piece can be detached from the floor board B 4 group laid on the joist J, and when the floor board B 4 is removed, the locking portion 20′a on the shorter side is removed. If the floor plate B 4 is lifted so as to rotate while holding the end that is locked to the side, the locking portion 20′a on the short side is longer than the locking portion 20′b on the long side. since elastically deformed with a small force, easily lifted as compared with the floorboard fixture a 8, easily removable.

次に、床板固定具Ａ11について説明する。床板固定具Ａ11は、床板固定具Ａ8 と比較して、前記浮上り防止部２８が外れ防止部２９に置き換わった構成である。即ち、床板固定具Ａ8 では、固定部１０に対して直角の起立角度θ4 をなして起立している係止部２０ｂの先端部分には浮上り防止部２８が形成されているが、床板固定具Ａ11の当該係止部２０ｂの先端部分には、断面Ｖ字形の外れ防止部２９が水平に形成されている。当該外れ防止部２９は、Ｖ字底部２９ａを係止溝４’の下面４ｂ’に当接した状態で、係止溝４’内に収納される。当該床板固定具Ａ11を使用する際に用いられる床板は、床板固定具Ａ8 と同様に床板Ｂ2 で良い。また、後述する床板Ｂ5 でも良い。図２４に（イ），（ロ）に床板固定具Ａ11が床板Ｂ5 を係止している状態を示す。図２４（イ）は、床板固定具Ａ11が床板Ｂ5 を係止している状態を正面から見た断面図であり、同（ロ）は、床板固定具Ａ11の全体斜視図である。図２４（イ）に示されるように、床板Ｂ5 を使用する場合には、摺接部２１が収納される係止溝４側の上端面１ａと、外れ防止部２９が収納される係止溝４’側の上端面１ａ’の垂直方向の長さ（即ち、床板本体Ｂ5aの厚さ）が等しいので、床板固定具Ａ11は、係止部２０ａの起立高さが床板固定具Ａ8 の場合よりも小さく、摺接部２１が係止溝４内に収納できるような構成となっている。床板固定具Ａ11を根太材Ｊ上にビス類６１で固定した後、床板Ｂ2 、上記の床板Ｂ2 の変形型Ｂ2 ’、又は床板Ｂ5 を敷設する場合には、根太材Ｊ上の床板固定具Ａ8 に床板Ｂ2 を敷設していく場合と同一で良い。 Next, a description will be given floor fixtures A 11. The floor board fixture A 11 has a configuration in which the lifting prevention section 28 is replaced with a detachment prevention section 29 as compared with the floor board fixture A 8 . That is, in the floor plate fixture A 8 , the anti-lifting portion 28 is formed at the front end portion of the locking portion 20 b that stands up at an upright angle θ 4 perpendicular to the fixed portion 10. the distal end portion of the locking portion 20b of the fixture a 11, disengagement preventing portions 29 of the V-shaped cross section is formed horizontally. The disengagement preventing portion 29 is accommodated in the locking groove 4 ′ in a state where the V-shaped bottom portion 29a is in contact with the lower surface 4b ′ of the locking groove 4 ′. The floor board used when using the floor board fixture A 11 may be the floor board B 2 in the same manner as the floor board fixture A 8 . In addition, it may be the floorboard B 5, which will be described later. Figure 24 (b) shows a state in which lock the floorboards fasteners A 11 is floorboard B 5 in (b). Figure 24 (b) is a sectional view of a state where the floorboard fixture A 11 is engaged the floor plate B 5 from the front, the (b) is a general perspective view of a floor plate fixture A 11 . As shown in FIG. 24 (b), when using the floor plate B 5 is an upper end surface 1a of the locking groove 4 side sliding contact portion 21 is accommodated, the engagement of disengagement preventing portion 29 is housed vertical length of the groove 4 'of the upper surface 1a' (i.e., floor thickness of the body B 5 a) since the same floorboard fixture a 11 is standing height floor fastener engaging portion 20a The sliding contact portion 21 is smaller than the case of A 8 and can be stored in the locking groove 4. After the floor board fixture A 11 is fixed on the joist board 61 with screws 61, when the floor board B 2 , the modified version B 2 ′ of the above floor board B 2 or the floor board B 5 is laid, If the floorboard fixture a 8 going laid floorboard B 2 may be the same as.

床板固定具Ａ11の効果について床板固定具Ａ8 と比較して説明する。なお、ここでは、両床板固定具Ａ8 ，Ａ11ともに床板Ｂ2 を係止するとして説明する。床板固定具Ａ8 において、床板Ｂ2 の係止溝４’に床板固定具Ａ8 の浮上り防止部２８が完全に収納されていて、その先端部分２８ａは、係止溝４’の上面４ａ’とほぼ当接状態にあり、床板Ｂ2 の出隅部５’が前記浮上り防止部２８の下端部２８ｂによって当接状態で係止されているので、床板Ｂ2 の浮上りは防止される。しかし、床板Ｂ2 が特に天然木である場合には、長時間の使用によって収縮する。このため、床板Ｂ2 の下端面１ｂ’は当接していた係止部２０ｂから離れ、出隅部５’と前記下端部２８ｂとが離れてしまうと、浮上り防止部２８による床板Ｂ2 の浮上り防止効果が低下してしまう。しかし、外れ防止部２９の場合には、床板Ｂ2 が収縮し、かつ浮き上っても、Ｖ字底部２９ａによって係止溝４’の下面４ｂ’は鉛直方向に押さえられるので、収縮した床板Ｂ2 の浮上りを防止し、根太材Ｊから外れるのを防止できる。更に、前記Ｖ字底部２９ａは係止溝４’の下面４ｂ’と長手方向Ｔに沿って当接しているので、使用により床板Ｂ2 が摩れる状況に陥っても、Ｖ字底部２９ａと前記下面４ｂ’との間に摩擦力が発生するため、床板Ｂ2 は長手方向Ｔにも幅方向Ｕ（根太材Ｊの長手方向Ｓ）にも摩れることがないので、床板Ｂ2 の摩れ防止効果が大きい。 The effect of the floor board fixture A 11 will be described in comparison with the floor board fixture A 8 . Here, the description will be made assuming that the floor plate B 2 is locked by both the floor plate fixtures A 8 and A 11 . In the floor plate fixture A 8 , the lifting prevention portion 28 of the floor plate fixture A 8 is completely stored in the locking groove 4 ′ of the floor plate B 2 , and the tip portion 28 a is the upper surface 4 a of the locking groove 4 ′. 'that there is substantially contact state, external corner portions 5 of the floor plate B 2' so is engaged in a contact state by the lower end 28b of the uplift prevention unit 28, the Ri floating floorboards B 2 is prevented The However, when the floor board B 2 is made of natural wood, the floor board B 2 shrinks due to long-time use. Therefore, the lower end face 1b of the floorboard B 2 'is apart from the locking portion 20b that abut against, external corner portion 5' when said lower portion 28b and moves away, the floorboard B 2 according to uplift prevention section 28 The anti-lifting effect will be reduced. However, in the case of disengagement preventing portion 29, the floor plate B 2 is contracted, and even up floats, since 'lower surface 4b' of the locking groove 4 by V-shaped bottom 29a is pressed in a vertical direction, and contracted floorboards B 2 can be prevented from rising and coming off from the joist J. Further, since the V-shaped bottom portion 29a is in contact with the lower surface 4b ′ of the locking groove 4 ′ along the longitudinal direction T, even if the floor board B 2 is worn by use, Since a frictional force is generated between the lower surface 4b 'and the floor board B 2 is not worn in the longitudinal direction T or the width direction U (the longitudinal direction S of the joist J), the floor board B 2 is worn. The prevention effect is great.

次に、図２５及び図２６を用いて床板Ｂ5 について説明する。図２５は、床板固定具Ａ11を介して床板Ｂ5 が根太材Ｊ上に固定された状態を示す正面断面図である。図２６は、根太材Ｊ上に固定された床板固定具Ａ11及び敷設された状態の床板Ｂ5 群を示す斜視図である。床板Ｂ5 は、断面長方形の床板本体Ｂ5aと、当該床板本体Ｂ5aの長手方向Ｔの両端部における下面に一体に取り付けられた係止溝形成具Ｂ5bとから成り、床板本体Ｂ5aの「台」に当該係止溝形成具Ｂ5bの「歯」がついた下駄状の構造になっている。図２５に示されるように、当該係止溝形成具Ｂ5bは、軽金属（アルミニウム等）の押出成形等で成形されて、幅方向Ｕの両端部には、床板固定具Ａ11の係止部２０ａ，２０ｂを係止可能な係止溝４，４’が形成されている。なお、係止溝形成具Ｂ5bは押出し成形品であるので、床板Ｂ3 のように収容溝９を形成すること（図２５には図示せず）、或いは床板固定具Ａ8 の変形型Ａ8 ’や床板固定具Ａ11等に合わせて、係止溝４，４’の幅及び深さ、出隅部５，５’の高さ等を容易に変更して加工することが可能である。従って、床板Ｂ1 ないしＢ4 のうち、上端面１ａ，１ａ’の垂直方向の長さが等しい床板Ｂ1 ，Ｂ3 及びＢ2 の変形型Ｂ2 ’を床板Ｂ5 のような構成にすることが可能である。また、係止溝形成具Ｂ5bには、係止溝形成具Ｂ5bと床板本体Ｂ5aとを一体化させるために、係止溝形成具Ｂ5bの所定箇所（図２６では１個の係止溝形成具Ｂ5bにつき４箇所）から床板本体Ｂ5aに対して垂直方向にビス類６４が挿通されている。更に、経済的な観点及び床板Ｂ5 の重量を考慮して、係止溝形成具Ｂ5b全体としては、複数個の枠体を並べたような構造となっている。根太材Ｊ上に床板Ｂ5 を敷設する際は、床板Ｂ1 ，Ｂ2 ’又はＢ3 と同様に、根太材Ｊ上に等間隔に固定されている床板固定具Ａ1 ないしＡ7 ，Ａ8'，Ａ9 又はＡ11に応じて、係止部２０の摺接部２１ないし２５、又は浮上り防止部２８、或いは外れ防止部２９が床板Ｂ5 の係止溝４，４’に収納されるようにして、床板Ｂ5 を根太材Ｊ上に固定していけばよい。なお、図２６に示されるように、床板本体Ｂ5 ａの長手方向Ｔに沿った係止溝形成具Ｂ5bの取付け位置の間隔が大きいと、床板Ｂ5 を前記各床板固定具Ａ1 ないしＡ7 ，Ａ8 ’，Ａ9 又はＡ11を介して根太材Ｊに敷設して使用した場合には、前記各取付け位置間において床板本体Ｂ5aが撓んでしまう可能性がある。このため、取り付けられた各係止溝形成具Ｂ5bの間に、係止溝形成具Ｂ5bと当該係止溝形成具Ｂ5bが固定されている根太材Ｊとの高さの和に相当する高さの根太材Ｊ’を配置してビス類６２で支持枠４１に固定する。当該根太材Ｊ’によって、当該床板本体Ｂ5aは補強されて前記撓みが防止される。 Next, the floor board B 5 will be described with reference to FIGS. 25 and 26. FIG. 25 is a front cross-sectional view showing a state where the floor board B 5 is fixed on the joist J through the floor board fixing tool A 11 . FIG. 26 is a perspective view showing the floor board fixture A 11 fixed on the joist J and the floor board B 5 group in a laid state. The floor board B 5 is composed of a floor board body B 5 a having a rectangular cross section and a locking groove forming tool B 5 b integrally attached to the lower surfaces of both ends in the longitudinal direction T of the floor board body B 5 a. It has a clog-like structure in which “the teeth” of the locking groove forming tool B 5 b is attached to the “base” of B 5 a. As shown in FIG. 25, the locking groove forming tool B 5 b is formed by light metal (aluminum or the like) extrusion molding or the like, and the floor plate fixing tool A 11 is locked at both ends in the width direction U. Locking grooves 4 and 4 ′ capable of locking the portions 20 a and 20 b are formed. Since the locking groove forming tool B 5 b is an extrusion-molded product, the receiving groove 9 is formed like the floor board B 3 (not shown in FIG. 25), or a modified version of the floor board fixing tool A 8 . 'to fit and floor fixtures a 11 or the like, locking grooves 4, 4' a 8 width and depth of, can be processed easily change the height, etc. of the external corner portions 5 and 5 ' is there. Therefore, of the floorboard B 1 to B 4, to the upper end face 1a, 1a 'in the vertical direction of the floorboards equal length B 1, B 3 and B 2 variant type B 2' of the structure, such as a floor plate B 5 It is possible. Also, the locking groove formers B 5 b, in order to integrate the locking groove formers B 5 b and floor plate body B 5 a, the predetermined portion (FIG. 26 of the locking groove forming member B 5 b Screws 64 are inserted perpendicularly to the floor plate main body B 5 a from four places per one locking groove forming tool B 5 b. Furthermore, considering the economical viewpoint and the weight of the floor board B 5 , the entire locking groove forming tool B 5 b has a structure in which a plurality of frames are arranged. When laying the floor board B 5 on the joist board J, the floor board fixtures A 1 to A 7 , A fixed on the joist board J at equal intervals, like the floor board B 1 , B 2 ′ or B 3. 8 ', depending on the a 9 or a 11, to no sliding contact portion 21 of the locking portion 20 25, or uplift prevention unit 28, or the disengagement preventing portion 29 engaging groove 4,4 floorboards B 5' housed in In this way, the floor board B 5 may be fixed on the joist J. As shown in FIG. 26, when the interval between the attachment positions of the locking groove forming tools B 5 b along the longitudinal direction T of the floor board main body B 5 a is large, the floor board B 5 is attached to each floor board fixing tool A 1. In addition, when used by laying on the joist J through A 7 , A 8 ′, A 9 or A 11 , the floor board body B 5 a may bend between the respective mounting positions. Therefore, during the engaging groove formers B 5 b mounted, the height of the joist material J of the locking groove formers B 5 b and the locking groove formers B 5 b is fixed A joist J ′ having a height corresponding to the sum is arranged and fixed to the support frame 41 with screws 62. The floor board body B 5 a is reinforced by the joist material J ′ to prevent the bending.

床板Ｂ5 は、全体が再生木、又はむくの天然木である従来の床板Ｂ1 ないしＢ4 に比べて、以下の効果が奏される。まず、床板Ｂ5 において、床板本体Ｂ5aは再生木や天然木からなる断面長方形の薄手の板材から構成されるので加工し易く、例えば再生木を床板形状に加工したり、天然木から成る木材を長手方向に沿って切削して係止溝４，４’を成形する等の成形加工を施す必要がない。また、係止溝形成具Ｂ5bは押出し成形品であるので高い加工精度を得ることができる。また、特に天然木では、天然木自体が高額で、かつ天然木材の切出しや係止溝４，４’の加工等の加工費も高額となるが、床板本体Ｂ5aは断面長方形の薄手の板材で良いので加工費が軽減でき、床板Ｂ5 一枚当たりの木材使用量も軽減されて経済的である。また、係止溝形成具Ｂ5bにより床板Ｂ5 の重量も軽減されるので、運搬が楽で作業し易い。更に、床板本体Ｂ5aと係止溝形成具Ｂ5bとは別体であるので、両者を一体化した状態で現場に搬入することも可能であるが、例えば車両の搬入スペースが限られている場合には、一体化させずに別々に搬送して、現場で両者を一体化させてから根太材Ｊ上に敷設していくことも可能となる。 The floor board B 5 has the following effects compared to the conventional floor boards B 1 to B 4 , which are entirely regenerated wood or peeled natural wood. First, the floor plate B 5, floor plate body B 5 a is easily processed because it is composed of thin sheet of rectangular cross section consisting of reproducing wood or natural wood, for example, to process the reproduced wood floor shape, made of natural wood There is no need to perform a forming process such as cutting the wood along the longitudinal direction to form the locking grooves 4, 4 ′. Further, since the locking groove forming tool B 5 b is an extruded product, high processing accuracy can be obtained. In particular, in the case of natural wood, the natural wood itself is expensive and the processing costs such as cutting out the natural wood and processing of the locking grooves 4 and 4 ′ are high, but the floorboard body B 5 a is thin and has a rectangular cross section. Since board materials are sufficient, processing costs can be reduced, and the amount of wood used per floor board B 5 is also reduced, which is economical. Further, since the weight of the floor plate B 5 is also reduced by the engagement groove formers B 5 b, easy transportation is working effortless. Furthermore, since the floorboard main body B 5 a and the locking groove forming tool B 5 b are separate bodies, it is possible to carry them into the field in an integrated state, but for example, the vehicle carrying space is limited. In this case, it is possible to carry them separately without being integrated and to lay them on the joist J after integrating them at the site.

上記各実施例では、長尺板材を床板Ｂ1 ないしＢ5 、及び固定材を根太材Ｊであるとして、床板固定具Ａ1 ないしＡ11を用いて、根太材Ｊに床板Ｂ1 ないしＢ5 を着脱する例について説明したが、敷設面が壁面、又は天井面であって、前記長尺板材が壁板材又は天井板材である場合においても、同様の構造で壁板材又は天井板材を固定材に着脱可能に固定することも可能であって、特定の一枚の壁板材又は天井板材の着脱ができる。 In each of the above embodiments, the long board is the floor boards B 1 to B 5 and the fixing material is the joist J, and the floor boards B 1 to B 5 are used as the joists using the floor board fixtures A 1 to A 11. In the case where the laying surface is a wall surface or a ceiling surface and the long plate material is a wall plate material or a ceiling plate material, the wall plate material or the ceiling plate material is used as a fixing material with the same structure. It can also be detachably fixed, and a specific single wall plate or ceiling plate can be attached and detached.

次に、図２７ないし図３１を用いて、長尺板材固定具及び長尺板材を建物の内壁又は壁面、及び天井面に適用する場合について、床板固定具Ａ1 ないしＡ11と相違する点のみを説明する。図２７（イ），（ロ）はそれぞれ、前方及び後方から見た壁板固定具Ａ12の斜視図である。図２８は、軽鉄下地材で組まれた壁下地Ｋ1 を構成するスタッドＪ1 上に、壁板固定具Ａ12を介して仕上材の壁用の長尺板材（以下、単に「壁板」という。）Ｂ6 が敷設された状態を示した図である。図２９（イ）ないし（ハ）は、壁板固定具Ａ12をスタッドＪ1 上に固定する工程を斜め前方から順番に見た図である。図３０は、壁板固定具Ａ12を介して壁板Ｂ6 がスタッドＪ1 上に固定された状態を示す正面断面図である。図３１は、軽鉄下地材で組まれた天井下地（裏桟）Ｋ2 を構成する野縁Ｊ2 上に、天井板固定具Ａ13を介して仕上材の天井用の長尺板材（以下、「天井板」という）Ｂ7 が敷設された状態を示した図である。なお、以下、長尺板材の長手方向Ｓ及び幅方向Ｕは、壁板Ｂ6 又は天井板Ｂ7 の長手方向及び幅方向であり、固定材の長手方向Ｓは、スタッドＪ1 及び野縁Ｊ2 の長手方向である。まず、図２７を用いて壁板固定具Ａ12について説明する。壁板固定具Ａ12は、アルミニウム等の軽金属、又は押出成形や射出成形可能な樹脂から成り、床板固定具Ａ1 と比較して、固定部１０にビス孔１１が形成されていない代わりに、当該固定部１０の下面中央部に挿入取付具１２が形成された構成になっている。挿入取付具１２は、長板状の挿入回転部１２ａと、当該挿入回転部１２ａの中央部から直立した挿入軸足部１２ｂとから成る断面Ｔ字形の形状であり、前記挿入回転部１２ａの短手方向が、前記固定部１０の長手方向と平行になるようにして、挿入取付具１２が前記固定部１０の下面中央部に固着されている。また、挿入回転部１２ａにおいて、固定部１０と対向する面の短手方向の縁部には、突条の止着部１２ｃが形成されている。 Next, with reference to FIGS. 27 to 31, only the points different from the floor plate fixtures A 1 to A 11 in the case where the long plate material fixture and the long plate material are applied to the inner wall or wall surface and ceiling surface of the building. Will be explained. Figure 27 (a), (b), respectively, a perspective view of a wall plate fasteners A 12 as viewed from the front and rear. FIG. 28 shows a long plate for a finishing material wall (hereinafter simply referred to as “wall plate”) on a stud J 1 constituting a wall base K 1 assembled with a light iron base material through a wall plate fixture A 12. This is a diagram showing a state where B 6 is laid. It 29 (a) to (c) is a view in sequence the steps of fixing the wall plate fastener A 12 on stud J 1 obliquely from the front. FIG. 30 is a front sectional view showing a state in which the wall plate B 6 is fixed onto the stud J 1 through the wall plate fixing tool A 12 . FIG. 31 shows a long plate material for a ceiling of a finishing material (hereinafter referred to as “finishing material ceiling”) via a ceiling plate fixture A 13 on a field edge J 2 constituting a ceiling base (back beam) K 2 assembled with a light iron base material. FIG. 7 is a view showing a state in which B 7 is called “ceiling board”. Hereinafter, the longitudinal direction S and the width direction U of the long plate material are the longitudinal direction and the width direction of the wall plate B 6 or the ceiling plate B 7 , and the longitudinal direction S of the fixing material is the stud J 1 and the field edge J. 2 in the longitudinal direction. First, the wall plate fixture A 12 will be described with reference to FIG. The wall plate fixture A 12 is made of a light metal such as aluminum or a resin that can be extruded or injection-molded. Instead of the floor plate fixture A 1 , the screw hole 11 is not formed in the fixed portion 10. An insertion fixture 12 is formed at the center of the lower surface of the fixed portion 10. The insertion fixture 12 has a T-shaped cross section composed of a long plate-shaped insertion rotation portion 12a and an insertion shaft foot portion 12b standing upright from the center of the insertion rotation portion 12a. The insertion fixture 12 is fixed to the center of the lower surface of the fixing part 10 so that the hand direction is parallel to the longitudinal direction of the fixing part 10. Moreover, in the insertion rotation part 12a, the fixing part 12c of a protrusion is formed in the edge part of the surface of the surface facing the fixing | fixed part 10 in the transversal direction.

次に、図２８及び図２９を用いて、壁板固定具Ａ12の固定材であるスタッドＪ1 について説明する。内装工事において、内壁や間仕切壁を構築する際には、軽量鉄骨（軽鉄）下地材で組まれた骨組み状の壁下地Ｋ1 に、石膏ボード等の仕上板を貼るのが一般的である。本発明における内壁や間仕切壁は、前記仕上板の代わりに、前記壁下地Ｋ1 上に壁板固定具Ａ12を介して壁板Ｂ6 が敷設された構成である。まず、壁下地Ｋ1 は、上端部と下端部にそれぞれ水平方向に走る断面コ字状の部材から成るランナ４２と、上下のランナ４２に挟まれた状態で等間隔に直立するスタッドＪ1 と、当該スタッドＪ1 に所定間隔で形成された挿通孔（図示せず）に挿通されて水平方向に走る振止め４３と、当該振止め４３を係止するスペーサ４４から構成される。壁板固定具Ａ12が固定されるスタッドＪ1 は、断面コ字状の軽鉄下地材が利用され、開口部と、該開口部に相対向する背面部と、一対の側面部とから成る。前記開口部の幅方向の両端には、一対の開口縁が相対向して形成されていて、それらの先端部は折り曲げられて、前記開口部内に入り込んでいる。スタッドＪ1 は、所定間隔をおいて、前記開口部がランナ４２の長手方向に沿った同一方向に向けられて立設される。また、各スタッドＪ1 の前記背面部には振止め４３が挿通される挿通孔が形成されていて、各スタッドＪ1 の前記背面部から起立する一対の側面部は、同一平面上に配置されている。当該一対の側面部のうち、正面手前側の側面部Ｊ1 ａには、壁板Ｂ6 の板材幅と同一又は整数分の一の長さに対応した所定間隔（ピッチＰ3 ）で、スタッドＪ1 の長手方向Ｓに沿って複数のスリーブ孔Ｈ1 が形成されている。当該スリーブ孔Ｈ1 の形状は、前記挿入取付具１２における挿入回転部１２ａの長板形状に対応しており、各スリーブ孔Ｈ1 は、その短手方向を前記方向Ｓと平行にして並列している。 Next, a stud J 1 that is a fixing member of the wall plate fixture A 12 will be described with reference to FIGS. In interior construction, when building an inner wall or a partition wall, it is common to put a finishing board such as a plaster board on a frame-like wall base K 1 made of a lightweight steel (light iron) base. . The inner wall and the partition wall in the present invention are configured such that a wall plate B 6 is laid on the wall base K 1 via a wall plate fixture A 12 instead of the finishing plate. First, the wall foundation K 1 includes a runner 42 made of a U-shaped member that runs in the horizontal direction at the upper end and the lower end, and a stud J 1 that stands upright at equal intervals while being sandwiched between the upper and lower runners 42. The stud J 1 is constituted by a vibration stopper 43 that is inserted through insertion holes (not shown) formed at predetermined intervals and runs in the horizontal direction, and a spacer 44 that locks the vibration stopper 43. The stud J 1 to which the wall plate fixing tool A 12 is fixed is made of a light iron base material having a U-shaped cross section, and includes an opening, a back surface opposite to the opening, and a pair of side surfaces. . A pair of opening edges are formed opposite to each other at both ends in the width direction of the opening, and the tip ends thereof are bent into the opening. The stud J 1 is erected with a predetermined interval with the opening directed in the same direction along the longitudinal direction of the runner 42. In addition, an insertion hole is formed in the back surface portion of each stud J 1 through which the brace 43 is inserted, and the pair of side surface portions that stand up from the back surface portion of each stud J 1 are arranged on the same plane. ing. Of the pair of side portions, the side portion J 1 a on the front side is studded at a predetermined interval (pitch P 3 ) corresponding to the plate material width of the wall plate B 6 or a fraction of an integer. A plurality of sleeve holes H 1 are formed along the longitudinal direction S of J 1 . The shape of the sleeve hole H 1 corresponds to the shape of the long plate of the insertion rotation part 12 a in the insertion fixture 12, and each sleeve hole H 1 is arranged in parallel with its short direction parallel to the direction S. ing.

次に、図２９を用いて、スタッドＪ1 に壁板固定具Ａ12を固定する方法について説明する。まず、壁板固定具Ａ12の挿入取付具１２を、スタッドＪ1 のスリーブ孔Ｈ1 の形状に合う向きにして当該スリーブ孔Ｈ1 に挿入し、挿入回転部１２ａ全体をスタッドＪ1 の裏側に挿通させる〔図２９（イ）〕。このとき、壁板固定具Ａ12の固定部１０の長手方向は、スタッドＪ1 の長手方向Ｓと平行であり、挿入回転部１２ａの短手方向はスリーブ孔Ｈ1 の短手方向と平行である。次に、挿入回転部１２ａをスタッドＪ1 に挿通させた状態で、前記壁板固定具Ａ12を左右どちらかに９０°回転させると〔図２９（ロ）〕、当該壁板固定具Ａ12は、挿入軸足部１２ｂを中心にして９０°回転し、壁板固定具Ａ12の固定部１０の長手方向は、前記方向Ｓと垂直になり、挿入回転部１２ａの短手方向はスリーブ孔Ｈ1 の短手方向と垂直になる。このため、当該挿入回転部１２ａはスタッドＪ1 に係止されて、スリーブ孔Ｈ1 から抜け出ることはない。更に、挿入回転部１２ａの短手方向の縁部における突条の止着部１２ｃがスタッドＪ1 の裏側面と当接した状態で、挿入回転部１２ａはスタッドＪ1 に止着されるので、挿入軸足部１２ｂはスリーブ孔Ｈ1 内を動くことなく壁板固定具Ａ12がスタッドＪ1 に固定される〔図２９（ハ）〕。以上の手順で、壁板Ｂ6 の板材幅に対応させた間隔でスリーブ孔Ｈ1 に壁板固定具Ａ12を複数個固定していけばよい。また、壁板固定具Ａ12が上記のような構成のため、スタッドＪ1 から壁板固定具Ａ12を取り外す際には、壁板Ｂ6 を壁板固定具Ａ12から取り外した後に、当該壁板固定具Ａ12を９０°再び回転させることによって、スタッドＪ1 の裏側で壁板固定具Ａ12を係止していた挿入回転部１２ａの短手方向が、再びスリーブ孔Ｈ1 の短手方向と平行になり、同時に止着部１２ｃもスタッドＪ1 の裏側面から外れるので、挿入回転部１２ａをスリーブ孔Ｈ1 から抜き出せばよい。 Next, a method for fixing the wall plate fixture A 12 to the stud J 1 will be described with reference to FIG. First, the insertion fitting 12 of wall plate fasteners A 12, in the direction to fit the shape of the sleeve hole H 1 of the stud J 1 is inserted into the sleeve hole H 1, the entire insert rotation portion 12a of the stud J 1 back [Fig. 29 (a)]. At this time, the longitudinal direction of the fixing portion 10 of the wall plate fixture A 12 is parallel to the longitudinal direction S of the stud J 1 , and the short direction of the insertion rotating portion 12 a is parallel to the short direction of the sleeve hole H 1. is there. Next, when the wall plate fixture A 12 is rotated 90 ° to the left or right while the insertion rotation portion 12a is inserted through the stud J 1 (FIG. 29 (b)), the wall plate fixture A 12 is rotated. is about the insertion axis leg section 12b is rotated 90 °, the longitudinal direction of the fixing portion 10 of the wall panel fastener a 12 becomes the direction S perpendicular, lateral direction of the insertion rotating portion 12a is the sleeve hole made in the lateral direction and vertical H 1.

The configuration of the wall plate B 6 used when using the wall plate fixture A 12 may be entirely made of natural wood or recycled wood, and may have locking grooves formed at both ends in the width direction U. A wall plate B 6 configured as shown in FIG. 30 may be used. That is, the wall plate B 6 is attached to the thin plate-like wall plate body B 6 a having a rectangular cross section and the lower surfaces of both end portions in the width direction of the wall plate body B 6 a to form the locking groove 4. consists locking groove forming member B 6 b for, the locking groove formers B 6 b in the U-shaped cross section of the fitting portion B, which is fitted to an end portion in the width direction U of the wallboard body B 6 a 6 c is provided. The engaging groove forming tool B 6 b is integrated with the wall plate main body B 6 a by the fitting portion B 6 c to constitute the wall plate B 6 as a whole. Further, in a cross-sectional view of the fitting portion B 6 c, since the lower surface abutting portion of the wall plate body B 6 a is formed longer than the upper surface abutting portion, the wall plate body B 6 a is stably It is inserted. Therefore, the both ends in the width direction U of the wallboard body B 6 a, by fitting the fitting portion B 6 c in the engaging groove formers B 6 b, the wall plate B 6, the wall plate body B 6 It has a clog-like structure with the “tooth” of the locking groove forming tool B 6 b on the “base” of a. Since the wall plate B 6 has a clog-like structure as described above, the following effects are exhibited. That is, when mounting the locking groove forming member B 6 b to the wall plate body B 6 a, there is no need to open a hole in the wall plate body B 6 a using screws and the like. Accordingly, it is possible to use a plate material made of a material that is difficult to attach with screws, such as a glass plate, or a material that is inconvenient if a hole is made, as the wall plate body B 6 a. Furthermore, the wall plate body B 6 a so hole is not opened, it is possible to reuse the wallboard body B 6 a after use for another purpose. Furthermore, when replacing the wall plate body B 6 a by changing the pattern, etc., it is easy to remove or fit the wall plate body B 6 a from the fitting portion B 6 c without using a tool or the like to remove the screws. The wall plate main body B 6 a can be detached from the locking groove forming tool B 6 b. Therefore, it consists of a wall board B 6 made of a board material such as a cedar wood board, a metal panel, a glass board, and an acrylic board, and a wall board body B 6 a to which a cross (wallpaper) having a different color and pattern is attached. One type or a plurality of types of wall plates B 6 and the like can be freely combined and laid on the stud J 1 via the wall plate fixture A 12 .

上記は、長尺板材固定具の壁への適用例として、軽鉄下地材から成る骨組み状の壁下地Ｋ1 （スタッドＪ1 ）に直接壁板固定具Ａ12を固定して、壁板Ｂ6 を敷設する例である。別の適用例として、前記壁下地Ｋ1 上に石膏ボード等の壁仕上板が貼られ、内壁又は間仕切壁として既に完成している壁体に適用することも可能である。この場合には、当該壁体面に新たに壁下地Ｋ1 のような骨組みを構築し、スタッドＪ1 状の固定材に壁板固定具Ａ12を固定して、壁板Ｂ6 を敷設すれば、従来の壁体と、壁板Ｂ6 群からなる壁体の二重壁構造となる。即ち、既にある内壁や間仕切壁を壊すことなく、その上に壁板Ｂ6 群から成る新たな壁体を作ることができる。また、敷設される壁板Ｂ6 の目地方向を、スタッドＪ1 の取付方向によって変えることができる。即ち、スタッドＪ1 の長手方向Ｓが垂直になるよう取り付ければ、各壁板Ｂ6 の長手方向Ｔが水平方向に沿うために、目地方向は水平となって「横目地」となる。一方、スタッドＪ1 の長手方向Ｓが水平方向に沿うように壁下地Ｋ1 の骨組みを改良したり、或いは、既にある内壁や間仕切壁の壁面にスタッドＪ1 状の固定材を水平に取り付けることによって、壁板Ｂ6 の目地方向は垂直方向となり「縦目地」となる。 As described above, as an example of application of a long plate material fixture to a wall, a wall plate fixture A 12 is directly fixed to a frame-like wall substrate K 1 (stud J 1 ) made of a light iron substrate, and a wall plate B This is an example of laying 6 . As another application example, a wall finishing board such as a gypsum board may be pasted on the wall base K 1 and applied to a wall body that has already been completed as an inner wall or a partition wall. In this case, if a new framework such as a wall base K 1 is constructed on the wall surface, the wall plate fixture A 12 is fixed to the stud J 1 shaped fixing material, and the wall plate B 6 is laid. , a conventional wall, a double wall structure of the wall consisting of wall plate B 6 group. That is, it is possible to make a new wall body made of the group of the wall plates B 6 on the inner wall and the partition wall without breaking them. Further, the joint direction of the wall plate B 6 to be laid can be changed depending on the mounting direction of the stud J 1 . That is, if the studs J 1 are attached so that the longitudinal direction S thereof is vertical, the longitudinal direction T of each wall plate B 6 is along the horizontal direction, so that the joint direction becomes horizontal and becomes “horizontal joint”. On the other hand, improve the framework of the wall base K 1 so that the longitudinal direction S of the stud J 1 is along the horizontal direction, or attach the stud J 1- shaped fixing material horizontally to the wall of the existing inner wall or partition wall. Thus, the joint direction of the wall plate B 6 becomes the vertical direction and becomes a “longitudinal joint”.
