Description

【0001】
【発明の属する技術分野】
本発明は、基礎床面とフロアパネルとの間に通信ケーブルや電力線を収容するスペースを確保するフリーアクセスフロア用のフロアパネルの支持装置に関するものである。
【0002】
【従来の技術】
フリーアクセスフロアにおけるフロアパネルは、支持脚によって基礎床面上に支持されるが、通常、基礎床面には不陸が発生していることから、支持脚を上下調節可能な構造にしてフロアパネルのレベルが出せるようにしている。又、ケーブル等の容量に応じてフロアパネルの高さを変える必要もあるが、これにも、支持脚を上下して対応している。この上下調節機構として、通常は、支持脚にネジを形成し、フロアパネルを支える支持板をこのネジに螺合してその高さを調節する構造をとっている。
【0003】
一方で、支持板にはフロアパネルの位置ずれ等を防止する特定の規制構造が施されていることから、支持板の向きはフロアパネルの向きに対して一定の相関関係になければならない。そこで、支持板の上にフロアパネルを支える敷板を支持板に対して相対回転可能に載せ、何枚かのフロアパネルを載置して敷板の向きを一定にしたままでも、支持板を回転させて上下できるようにしている。
【0004】
ところで、支持板(敷板)を所定の高さに合わせた後は、支持板の螺合部にガタがない状態で固定され(通常、支持板の螺合部には嵌め合いによるガタ(隙間)がある)、フロアパネルに繰り返し荷重等がかかっても、敷板が低下しないことが望まれる。さもないと、敷板とフロアパネルとの間に隙間が生じ、ガタ付きや歩行時の音鳴りが発生したり、床面に凹凸が発生したりする。このためには、支持板が支持脚に対して緩まない(下降方向に回動すること)工夫が必要であるが、従来は、この緩み防止構造として、支持板の螺合部の下方に別のナットを螺合して支持板に強く押し付ける、所謂ダブルナット構造を採用していた。
【0005】
【発明が解決しようとする課題】
しかし、このナットは、その締緩操作がやり難く、施工のコストが高くついていた。又、ダブルナットが緩むと、まったく効果がなくなってしまっていた。そこで、もっと効率的で信頼性の高い方法が望まれていたのであるが、特許第2727855号では、パネル押えをフロアパネルのコーナー部の上方から支持板に対して締め込む構造とし、更に、敷板と支持板との間に一定角度以上の相対的回動を規制する制限手段を設けて対処している。
【0006】
パネル押えと支持板との締め付けが緩まない限り、支持板が低下することはないが、前記した先行例のものも、回動が許容される範囲での緩みは避けられない。従って、僅かではあるが、支持板が下がり、これに基づくガタ付きや床面の凹凸等が生ずる虞がある。又、フロアパネルを敷設するにあたり、予め支持板を所定高さに調整しておくが、その際、支持板の螺合部のガタ、基礎床面の不陸による支持脚の傾き、構成部材の製造誤差等が原因で、フロアパネルを設置してパネル押えを締め込むまでは、床面が平坦に仕上がっているかどうか分からない。このため、床面に凹凸があれば、再度高さを調整する必要があるが、フロアパネルを敷板上に載せたままの状態では回動許容範囲を超えて支持板を上下させることができないから、支持板上に載っている4枚のフロアパネルを全て除去した状態で作業しなければならず、調整に非常に手間がかかるという問題が生ずる。
【0007】
本発明は、支持板と敷板との間に、支持板の敷板に対する強制回動によって相互の係合が解かれる係合構造を設けることで、この問題を解決したものである。
【0008】
以上の課題の下、本発明は、基礎床面上に固定される接地板から雄ネジ体を立設した支持脚と、上面周辺に平坦部を形成して雄ネジ体に螺合する雌ネジ部を有する支持板と、上面にフロアパネルのコーナー部に嵌合して位置規制する起立部と底面を載せる載置部とを形成して支持板に被せられる敷板と、雄ネジ体に螺合してフロアパネルのコーナー部を敷板上に挟圧するパネル押えと、から構成されるフロアパネルの支持装置において、支持板と敷板の向合部位に、相互に係合する係合構造を設ける他、この係合構造をフロアパネルで位置規制される敷板に対する支持板の強制回動によって相互の係合が解かれるものにしたことを特徴とするフロアパネルの支持装置を提供したものである。
【0009】
以上の手段により、支持板と敷板とは係合構造で係合しているとともに、この係合構造は、敷板に対する工具等による支持板の強制回動によって相互の係合が解かれ、通常のフロアパネルの使用状態における回動は規制するものであるから、フロアパネルに対する繰り返し荷重や振動によって支持板は緩んで下がることはなく、パネルのガタ付きも床面の凹凸も生じない。一方で、高さ調節等に際し、敷板を一定の向きにしたままで、支持板を工具等で強制的に回して上下調整させるには、何枚かのパネルは載ったままでも、1枚のフロアパネルを外せば何ら支障なくできる。
【0010】
【発明の実施の形態】
以下、本発明の実施の形態を図面を参照して説明する。図1は本発明の一例を示すフロアパネルの支持装置の斜視図、図2は平面図、図3は図2のAOA断面図であるが、このフロアパネルの支持装置は、基礎床面1上に置かれる支持脚2と、支持脚2に上下調節可能に支えられる支持板3と、支持板3に被せられてフロアパネル(以下、パネルという)4を載せる敷板5と、支持脚2に係合してパネル4を押さえつけるパネル押え6とからなる。
【0011】
このうちの支持脚2は、基礎床面1に固定される接地板7の中央からパネル4を支持するのに十分な太さ(M12)を有する雄ネジ体8を立設したものであり、それには、接地板7の中央に孔9をあけ、この孔9に雄ネジ体8の頭部8aをかしめる構造をとっている。但し、かしめ以外の固定法、例えば、溶接やビス止めであってもよい。接地板7は、金属製の薄板(厚さ1mm位)で構成されていることから、孔9を中心に放射状に延びる何本かの補強ビード10を形成し、必要な強度を確保している。
【0012】
接地板7は、パネル4の集合コーナー部に設置されるものであるから、基礎床面1上での設置位置は決まっている。このため、角を面取りし、その中央に切込11を設けておき、この切込11を基礎床面1上に引く墨出し基準線に合わせるようにしている。更に、接地板7は、接着剤によって基礎床面1上に固定されるが、この場合、多数の貫通孔12を形成しておき、接着剤がこの貫通孔12を通って表裏に連続するようにして固定の強化を図っている。尚、接地板7の固定は、コンクリート釘等による締結であってもよい。
【0013】
図5は支持板3の平面図、図7は一部断面側面図であるが、支持板3は、上面周辺が平坦部13、中央が凹陥部14に形成された円板形のカップ体15と、前記した雄ネジ体8に螺合できる雌ネジ部16とからなる。この場合の雌ネジ部16は、カップ体15の中央に孔17を形成し、この孔17にナットをかしめることで構成している(この他に溶接等による一体化構造も考えられる)。支持板3も、金属板の成形品であり、この上に四枚のパネル4を載せても変形等しない程度の厚み(2〜3mm)や大きさに設定されている。
【0014】
図8は敷板5の平面図、図9は図8のBOB断面図であるが、敷板5は、下方に存する支持板3や上方に載せられるパネル4との金属接触を避けるためにPP等の樹脂の成形品で構成されている。その形状は、中央に貫通孔18が形成された本体部19から張出部20が周辺に円板形に張り出し、張出部20の周端から垂下部21が下方に屈曲しているものである。
【0015】
この場合、敷板5を支持板3の上に装着した場合、本体部19は支持板7の凹陥部14の底に当たり、張出部20は支持板3の平坦部13に接触する状態で被さる他、垂下部21が平坦部13の外方を所定隙間を保って覆う状態となる。図10は垂下部21の一部断面図であるが、垂下部21の下端には、被せるときには支持板3の外端を通過して係止し、上方への抜出が防がれる複数の(本例では180°間隔で二個)爪体22が設けられている。
【0016】
張出部20の上面には、この上にパネル4を置いた場合、そのコーナー部の直角な側辺が当たって位置規制する四個の起立部23が形成されており、その外方端部両側を張り出させてパネル4の側辺に当てるようにしている。起立部23の構造は、例えば、パネル4の底面に設けた嵌合孔に挿入可能なピン状のもの等、パネル4の水平方向の位置を規制するものであればよい。また、本体部19外面の各起立部23同士の中間位置に、パネル4のコーナー部先端の側辺に当てて位置規制する凸条19bが形成されている。このように、パネル4のコーナー部において3点を当てるようにしてやれば、パネル4と敷板5の位置(角度)を正確に規制することができる。起立部23を除く部位には、パネル4の底面を載せる平坦な載置部24が形成されている。更に、本体部19の貫通孔18の径は、ここに挿入されて来るパネル押え6の外径と一致させてある。
【0017】
図11はパネル押え6の平面図、図12は一部断面側面図、図13は底面図であるが、パネル押え6も、PC等の樹脂の成形品であり、中央に前記した雄ネジ体8に螺合できる雌ネジ部25が形成された筒状の本体部26の上部にパネル4のコーナー部に形成された低段部に沈み込むことができる鍔部27が形成されたものである。又、本体部26の上部中央には、これを回す工具が係合できる係合部28も形成されている。この係合部28は、中央に六角レンチを挿入できる六角孔29が、外周にボックスレンチが挿入できる鋸歯部30がそれぞれ形成された二重式のものである。
【0018】
ここで用いられるパネル4は、図3にみられるように金属製薄板のフラットな上面板31に対して断面ハット形をした下面板32を端部でかしめて一体化したものであり、下面板32の起立壁33は、上面板31の端から所定長さ控えたものである。従って、敷板5の起立部23に当たる側辺は、この下面板32の起立壁33ということになる。更に、上面板31のコーナー部には、低段部34が形成されているとともに、その端は、四分の一円形状に切り欠かれた切欠35を形成している。
【0019】
この場合の切欠35の大きさは、パネル押え6の本体部26の挿入を許容するものにしてあり、その本体部26は、この切欠35が集合した円形孔に入り込んで鍔部27が低段部34を押え付けるものとなるようにしてある(この場合の鍔部27の厚みと低段部34の深さは、ほぼ同じにして鍔部27が低段部34から飛び出ないようにしてある)。尚、このときの低段部34の底面は、パネル押え6の締め込みによって敷板5の本体部19の頂面に形成された凹陥穴19aに押し当てられており、パネル押え6のそれ以上の締め込みが規制される。結局、低段部34は弾性変形した状態でパネル押え6と敷板5とで上下から挟圧されて固定されるものとなり、パネル押え6の緩み止め効果を発揮する。又、凹陥穴19aに低段部34を嵌め込むことで、更なるパネル4の水平方向の位置規制を行うようにしている。
【0020】
以上の各機器を用いてパネル4を敷設するのであるが、ここでその手順の概略を説明しておく。先ず、基礎床面1上に引いた墨出し基準線を基に、支持板3を規定高さよりも低く取り付けた支持脚2のそれぞれを所定の位置に固定する作業を行なう。次に、敷板5が所定の向きになるよう支持板3を回して規定の高さまで上げる。ここで、支持板3の上昇高さは、基礎床面1の不陸等を考慮したものであり、支持板3のレベルはおおよそ揃えられる。
【0021】
次いで、敷板5の上にパネル4を敷いて行くのであるが、この際、パネル4のコーナー部の側辺32を二つの起立部23の間に挿入して底面32を載置部24の上に載せて位置を合わせ、最後に、パネル押え6を支持板3の貫通孔18に挿入してその雌ネジ部25を支持脚2の雄ネジ体8に螺合し、鍔部27と敷板6とでパネル4の低段部34を強く挟圧する。このときパネル4は敷板に添うよう若干変形するので、支持板3の高さや傾き、パネル4の厚み等に多少のバラツキがあっても吸収することができる。
【0022】
ところで、パネル4の敷設後、パネル4に繰り返し荷重等がかかって支持板3が下方に移動する方向に回動したとすると、床面に凹凸が生じたり、パネル4と敷板5又は鍔部27との間に隙間が生じ、ガタ付きや音鳴りが発生し、又、パネル4の敷設時に支持板3の高さを再調整する際に、支持板3上のパネル4枚全てを除去する必要があることは前述したとおりである。このため、これを防ぐ手段が求められるのであるが、本発明は、これを以下のように構成したものである。
【0023】
その構成は、支持板3と敷板5との適当な向合部位に、相互に係合する係合構造36を設けるのである。そして、敷設に際しては、支持板3をこれに被せられる敷板5の起立部23の側面方向がパネル4の側辺方向と平行になる正規の向きになるよう回転させ、この状態にしてパネル押え6で締め付けるのである。
【0024】
ところで、この正規状態にすると、支持板3の向きも拘束されるから、その高さは、厳密には設定高さと違ってくることがあるが、雄ネジ体8と雌ネジ部16の螺合部にはガタ(隙間)があり、基礎床面1の不陸によって支持脚2には傾きも生じているから、厳密に設定高さに合わせることは現実に不可能であるし、更に、パネル押え6を締め込むことで、パネルが若干変形して多少のバラツキは吸収される。又、雄ネジ体8のピッチは小さいものである(支持体3を90°回しても0.2mm程度しか高さは変化しない)から、その誤差は完全に吸収できるものである。
【0025】
この場合の係合構造36は、工具等による敷板5に対する支持板3の強制回動は許容し、通常のパネル4の使用状態における回動は規制するものである。図4は係合構造36の一例を示す敷板5と支持板3の平面図であるが、敷板5の垂下部21等に内方に突起する突起体37を形成したものであり、支持板3にこの突起体37を受け入れる外周から切れ込む切欠38を形成したものである。この場合において、切欠38の切込傾斜面38aを支持板3の回動を規制する急なものとしている。その一方で、切欠38と外周との接続部をアール形状とし、又、突起体37の断面形状を半円形状とし、更には、突起体37の上方の載置部24に窓39を設けたり、垂下部21を樹脂によって構成する等して、支持板3を工具等によって回転させた際には、突起体37を切欠38から遠ざける方向に変位させて係合を解くことができるようにしている。
【0026】
これにより、突起体37が切欠38に入り込むと、通常のパネル4の使用状態において繰り返し荷重や振動が作用しても、支持板3の回動は規制されるから、支持板3が低下してパネル抑え6に対して緩まない。一方で、敷板5の高さを調節するときには、敷板5上に何枚かのパネル4を載せた状態等、敷板5の向きを一定にして支持板3を上昇又は下降させようとするときも、敷板5はそのままで支持板3のみを回すこともできるから支障を来さない。尚、支持板3を回しての敷板5の高さ調整は、突起体37と切欠38が合致した位置にするのが標準であるが、係合構造36は節動感をもって係合するので、係合位置がわからないといった心配はない。但し、突起体37上方の載置部24に形成した窓39によって目視で確認することもできる。
【0027】
この場合、信頼性を高めるために、係合構造36は複数個所に設けるのがよい。具体的には、突起体37、切欠38共に複数個設け、しかも、一つの突起体37が特定の切欠38に嵌まり込んだ場合、他の突起体37も他の切欠38に嵌まり込むように位相を合わせておくのが好ましい。本例では、切欠38は60°間隔で6個、突起体37は180°間隔で2個設けているが、勿論、これにこだわらない。
【0028】
図6は切欠38の他の例を示す要部(図5のB部)平面図であるが、この場合においては、切欠38の切込傾斜面38aが支持板3が上昇する方向へはその強制回動を積極的に許容する緩なものであり、下降する方向へは前記実施例と同様に急なものにしてある。これにより、通常のパネル4使用状態における支持板3の下降方向の回動は前記実施例と同様に規制される。一方で、敷板5の高さを調節しようとするときには、敷板5上に何枚かのパネル4を載せた状態等、敷板5の向きを一定にして支持板3を上昇させようとするときは、前記実施例に比べて軽い操作力で支持板3のみを回すことができる。勿論、支持板3を強制的に工具等によって回動下降させようとするときには、前記実施例と同様に行うことができる。更に、図示は省略するが、以上の係合構造36は、支持板3と敷板5の重合面に形成してもよい。
【0029】
更に、パネル押え6が支持板3に対して単独で緩むことも考えられ、そうなると、同様に支持板3にガタが発生する。そこで、本発明では、パネル押え6と敷板5との間に緩み防止構造42を施している。本例の緩み防止構造42は、敷板5の貫通孔18の内周に何個かの突起43を形成し(図8、図9)、パネル押え6の本体部26の外周にこの突起43が入り込むことができる溝44を形成したものである(図12、図13)。
【0030】
この場合、突起43の両隣には凹陥部45を形成し、本体部26の外周が通過するときには変形できるようにして雄ネジ体8への締緩操作のときの抵抗を少なくしている。尚、パネル押え6のネジ込み終了位置は、この突起43と溝44とが合致した位置が好ましいが、途中であってもかまわない。この場合、パネル押え6が緩むと、いずれかの突起43と溝44が合致し、それ以上の緩みに歯止めがかかる。この意味から、突起43と溝44は、位相を合わせてそれぞれ複数個設けるのがよい。
【0031】
【発明の効果】
以上、本発明によれば、支持板と敷板とは係合構造で係合しているとともに、この係合構造は、工具等による敷板に対する支持板の強制回動は許容し、通常のパネルの使用状態における回動は規制するものであるから、パネルに繰り返し荷重等がかかっても、支持板は緩んで下がることはなく、敷板とパネルとの間に隙間ができてガタ付きや音鳴りが発生したり、床面に凹凸が生じたりする事態が避けられる。一方で、高さ調節等に際し、パネルを載置して敷板を一定の向きにしたままで、工具等によって支持板を強制的に回して上昇又は下降させる操作も、1枚のパネルを外しさえすれば何ら支障なくできる。
【0032】
この場合において、係合構造を複数設けると、信頼性が増す。更に、パネル押えの緩みを防止する緩み防止手段を設けると、パネル押えの緩みに基づくパネルのガタ付きや音鳴りも発生しない。

BACKGROUND OF THE INVENTION
The present invention relates to a floor panel support device for a free access floor that secures a space for accommodating a communication cable and a power line between a basic floor surface and a floor panel.
[0002]
[Prior art]
The floor panel in the free access floor is supported on the foundation floor surface by the support legs, but usually the foundation floor is uneven, so the support legs can be adjusted up and down to make the floor panel The level of can be put out. In addition, it is necessary to change the height of the floor panel in accordance with the capacity of the cable or the like. This vertical adjustment mechanism usually has a structure in which a screw is formed on a support leg, and a support plate that supports the floor panel is screwed to this screw to adjust its height.
[0003]
On the other hand, since the support plate is provided with a specific restricting structure for preventing the positional deviation of the floor panel, the direction of the support plate must have a certain correlation with the direction of the floor panel. Therefore, the floor plate that supports the floor panel is placed on the support plate so as to be rotatable relative to the support plate, and even if several floor panels are placed and the direction of the floor plate is kept constant, the support plate is rotated. Can be moved up and down.
[0004]
By the way, after the support plate (laying plate) is adjusted to a predetermined height, it is fixed in a state where there is no backlash in the screwed portion of the support plate (usually, the screwed portion of the support plate is loose due to fitting (gap)) However, it is desirable that the floorboard does not decrease even when a load is repeatedly applied to the floor panel. Otherwise, there will be a gap between the floor plate and the floor panel, which may cause rattling or noise during walking, or unevenness on the floor surface. For this purpose, it is necessary to devise a means that the support plate does not loosen with respect to the support leg (turns in the downward direction). However, conventionally, as this loosening prevention structure, a separate structure is provided below the threaded portion of the support plate. A so-called double nut structure is employed in which the nut is screwed and pressed firmly against the support plate.
[0005]
[Problems to be solved by the invention]
However, this nut is difficult to tighten and tighten, and the construction cost is high. Also, if the double nut was loosened, the effect was completely lost. Therefore, a more efficient and reliable method has been desired. However, in Japanese Patent No. 2727855, the panel presser is tightened against the support plate from above the corner of the floor panel. A limiting means for restricting the relative rotation of a certain angle or more is provided between the support plate and the support plate.
[0006]
As long as the clamp between the panel presser and the support plate is not loosened, the support plate is not lowered. However, in the preceding example, the looseness in the range in which the rotation is allowed is unavoidable. Therefore, although it is slight, there is a possibility that the support plate is lowered, and there is a backlash or unevenness of the floor surface due to this. Also, when laying the floor panel, the support plate is adjusted in advance to a predetermined height. At that time, the backlash of the screwing portion of the support plate, the inclination of the support leg due to the unevenness of the foundation floor surface, Until the floor panel is installed and the panel presser is tightened due to manufacturing errors, it is not known whether the floor is finished flat. For this reason, if there are irregularities on the floor surface, it is necessary to adjust the height again, but if the floor panel remains on the floor plate, the support plate cannot be moved up and down beyond the allowable rotation range. The work must be performed in a state in which all the four floor panels placed on the support plate are removed, and there is a problem that adjustment is very troublesome.
[0007]
The present invention solves this problem by providing an engagement structure between the support plate and the floor plate so that the mutual engagement is released by forced rotation of the support plate with respect to the floor plate.
[0008]
Under the above-described problems, the present invention provides a support leg in which a male screw body is erected from a ground plate fixed on a foundation floor surface, and a female screw that forms a flat portion around the upper surface and is screwed into the male screw body. a support plate having a section, a floor plate for covering the support plate to form a mounting portion mounting the upright portion and a bottom surface positioned regulating fitted to a corner portion of the floor panel on the upper surface, screwed to the male screw member In addition, in the floor panel support device composed of a panel presser that clamps the corner portion of the floor panel on the floor plate, in addition to providing an engaging structure that engages with each other at the facing portion of the support plate and the floor plate, According to another aspect of the present invention, there is provided a floor panel support device in which the engagement structure is such that the mutual engagement is released by forced rotation of the support plate with respect to the floor plate whose position is regulated by the floor panel.
[0009]
By the above means, the support plate and the floor plate are engaged with each other by an engagement structure, and the engagement structure is released from the mutual engagement by the forced rotation of the support plate by a tool or the like with respect to the floor plate. Since the rotation of the floor panel in use is restricted, the support plate does not loosen due to repeated loads or vibrations on the floor panel, and no backlash or unevenness of the floor surface occurs. On the other hand, when adjusting the height, etc., to keep the floor plate in a certain direction and to force the support plate to turn up and down with a tool, etc. If you remove the floor panel, you can do it without any problems.
[0010]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a perspective view of a floor panel support device showing an example of the present invention, FIG. 2 is a plan view, and FIG. 3 is an AOA cross-sectional view of FIG. The support leg 2 placed on the support leg 2, the support plate 3 supported by the support leg 2 so as to be adjustable in the vertical direction, the floor board 5 on which the floor panel (hereinafter referred to as the panel) 4 is placed, and the support leg 2. And a panel presser 6 for pressing the panel 4 together.
[0011]
Of these, the support leg 2 is an upright male screw body 8 having a thickness (M12) sufficient to support the panel 4 from the center of the ground plate 7 fixed to the foundation floor 1. For this purpose, a hole 9 is formed in the center of the ground plate 7, and the head 8 a of the male screw body 8 is caulked in the hole 9. However, a fixing method other than caulking, for example, welding or screwing may be used. Since the ground plate 7 is composed of a thin metal plate (thickness of about 1 mm), several reinforcing beads 10 extending radially around the hole 9 are formed to ensure the necessary strength. .
[0012]
Since the ground plate 7 is installed at the gathering corner portion of the panel 4, the installation position on the foundation floor 1 is determined. For this reason, the corner is chamfered, and a notch 11 is provided at the center thereof so that the notch 11 is aligned with the inking reference line drawn on the foundation floor surface 1. Further, the ground plate 7 is fixed on the foundation floor 1 by an adhesive. In this case, a large number of through holes 12 are formed so that the adhesive continues through the through holes 12 on the front and back sides. In order to strengthen the fixation. The ground plate 7 may be fixed by concrete nails or the like.
[0013]
FIG. 5 is a plan view of the support plate 3 and FIG. 7 is a partially sectional side view. The support plate 3 is a disc-shaped cup body 15 having a flat portion 13 around the upper surface and a recessed portion 14 at the center. And a female screw portion 16 that can be screwed into the male screw body 8 described above. The female screw portion 16 in this case is configured by forming a hole 17 in the center of the cup body 15 and caulking a nut in the hole 17 (in addition, an integrated structure by welding or the like is also conceivable). The support plate 3 is also a molded product of a metal plate, and is set to have a thickness (2 to 3 mm) and size that do not deform even when four panels 4 are placed thereon.
[0014]
8 is a plan view of the floor plate 5, and FIG. 9 is a BOB cross-sectional view of FIG. 8. The floor plate 5 is made of PP or the like to avoid metal contact with the support plate 3 below and the panel 4 placed above. It consists of a molded product of resin. The shape is such that a projecting portion 20 projects from the main body portion 19 having a through hole 18 at the center to a disk shape around the periphery, and the hanging portion 21 is bent downward from the peripheral end of the projecting portion 20. is there.
[0015]
In this case, when the floor plate 5 is mounted on the support plate 3, the main body portion 19 hits the bottom of the recessed portion 14 of the support plate 7, and the overhanging portion 20 covers the flat portion 13 of the support plate 3 in contact with it. The drooping portion 21 covers the outside of the flat portion 13 with a predetermined gap. FIG. 10 is a partial cross-sectional view of the drooping portion 21, but the lower end of the drooping portion 21 is locked by passing through the outer end of the support plate 3 to prevent the drooping portion 21 from being pulled upward. Claw bodies 22 are provided (two in this example at intervals of 180 °).
[0016]
On the upper surface of the overhanging portion 20, when the panel 4 is placed thereon, four upright portions 23 are formed, which are positioned by the right side sides of the corner portions, and the outer end portions thereof are formed. Both sides are overhanging so as to contact the side of the panel 4. The structure of the standing portion 23 may be any structure that regulates the horizontal position of the panel 4, such as a pin that can be inserted into a fitting hole provided on the bottom surface of the panel 4. Further, at the intermediate position between the standing parts 23 on the outer surface of the main body part 19, a ridge 19 b is formed that is positioned against the side of the front end of the corner part of the panel 4. As described above, if three points are applied to the corner portion of the panel 4, the positions (angles) of the panel 4 and the floor plate 5 can be accurately regulated. A flat placement portion 24 on which the bottom surface of the panel 4 is placed is formed at a portion excluding the standing portion 23. Further, the diameter of the through hole 18 of the main body 19 is made to coincide with the outer diameter of the panel presser 6 inserted therein.
[0017]
11 is a plan view of the panel retainer 6, FIG. 12 is a partially sectional side view, and FIG. 13 is a bottom view. The panel retainer 6 is also a resin molded product such as a PC, and has the male screw body described above in the center. 8 is formed with a collar portion 27 that can sink into a lower step portion formed in a corner portion of the panel 4 on an upper portion of a cylindrical main body portion 26 in which a female screw portion 25 that can be screwed into the body 8 is formed. . In addition, an engaging portion 28 that can be engaged with a tool that turns the main body portion 26 is formed at the upper center of the main body portion 26. The engaging portion 28 is a double type in which a hexagonal hole 29 into which a hexagon wrench can be inserted is formed at the center, and a sawtooth portion 30 into which a box wrench can be inserted into the outer periphery.
[0018]
As shown in FIG. 3, the panel 4 used here is obtained by integrating a bottom face plate 32 having a hat shape in cross section with a flat top face plate 31 made of a metal thin plate at an end portion. The 32 standing walls 33 are provided with a predetermined length from the end of the upper surface plate 31. Accordingly, the side of the floor plate 5 that corresponds to the standing portion 23 is the standing wall 33 of the bottom plate 32. Furthermore, a low step portion 34 is formed at a corner portion of the upper surface plate 31, and an end thereof forms a cutout 35 cut out in a quarter circle shape.
[0019]
In this case, the size of the cutout 35 allows insertion of the main body portion 26 of the panel retainer 6. The main body portion 26 enters the circular hole in which the cutout 35 is assembled, and the flange portion 27 is lowered. (In this case, the thickness of the flange portion 27 and the depth of the lower step portion 34 are substantially the same so that the flange portion 27 does not jump out of the lower step portion 34). ). Note that the bottom surface of the low step portion 34 at this time is pressed against a recessed hole 19 a formed in the top surface of the main body portion 19 of the floor plate 5 by tightening the panel retainer 6, and more than that of the panel retainer 6. Tightening is regulated. Eventually, the low step portion 34 is elastically deformed to be clamped and fixed by the panel presser 6 and the floor plate 5 from above and below, and exhibits the effect of preventing the panel presser 6 from loosening. Moreover, the horizontal position of the panel 4 is further regulated by fitting the low step portion 34 into the recessed hole 19a.
[0020]
The panel 4 is laid using each of the above devices, and the outline of the procedure will be described here. First, based on the ink marking reference line drawn on the base floor surface 1, an operation of fixing each of the support legs 2 to which the support plate 3 is attached lower than a specified height is performed at a predetermined position. Next, the support plate 3 is turned up to a specified height so that the floor plate 5 is in a predetermined direction. Here, the rising height of the support plate 3 takes into account the unevenness of the foundation floor surface 1 and the level of the support plate 3 is roughly aligned.
[0021]
Next, the panel 4 is laid on the floor plate 5. At this time, the side 32 of the corner portion of the panel 4 is inserted between the two upright portions 23, and the bottom surface 32 is placed on the mounting portion 24. Finally, the panel retainer 6 is inserted into the through hole 18 of the support plate 3, and the female screw portion 25 is screwed into the male screw body 8 of the support leg 2. Thus, the low step portion 34 of the panel 4 is strongly pinched. At this time, since the panel 4 is slightly deformed so as to follow the floor plate, even if there is some variation in the height and inclination of the support plate 3, the thickness of the panel 4, etc., it can be absorbed.
[0022]
By the way, after the panel 4 is laid, if a load or the like is repeatedly applied to the panel 4 and the support plate 3 is rotated in a direction to move downward, the floor surface is uneven, or the panel 4 and the floor plate 5 or the flange 27 A gap is generated between the panel 4 and the sound, and noise is generated. When the height of the support plate 3 is readjusted when the panel 4 is laid, all four panels on the support plate 3 must be removed. As described above, there is. For this reason, means for preventing this is required, but the present invention is configured as follows.
[0023]
In the configuration, an engagement structure 36 that engages with each other is provided at an appropriate facing portion between the support plate 3 and the floor plate 5. When laying, the support plate 3 is rotated so that the side surface direction of the upright portion 23 of the floor plate 5 that covers the support plate 3 is in a normal direction parallel to the side direction of the panel 4, and in this state, the panel presser 6 Tighten with.
[0024]
By the way, in this normal state, since the direction of the support plate 3 is also restrained, the height may be different from the set height in a strict sense, but the male screw body 8 and the female screw portion 16 are screwed together. Since there is a backlash (gap) in the part and the support leg 2 is inclined due to the unevenness of the foundation floor surface 1, it is actually impossible to precisely match the set height. By tightening the presser 6, the panel is slightly deformed and some variation is absorbed. Moreover, since the pitch of the male screw body 8 is small (the height changes only by about 0.2 mm even if the support 3 is rotated 90 °), the error can be completely absorbed.
[0025]
In this case, the engagement structure 36 allows the support plate 3 to be forcibly rotated with respect to the floor plate 5 by a tool or the like, and restricts the rotation of the normal panel 4 in the use state. FIG. 4 is a plan view of the base plate 5 and the support plate 3 showing an example of the engagement structure 36, in which a protrusion 37 projecting inward is formed on the hanging portion 21 of the base plate 5. In addition, a notch 38 cut out from the outer periphery for receiving the protrusion 37 is formed. In this case, the cut inclined surface 38 a of the notch 38 is abrupt to restrict the rotation of the support plate 3. On the other hand, the connecting portion between the notch 38 and the outer periphery is rounded, the cross-sectional shape of the protrusion 37 is semicircular, and a window 39 is provided on the mounting portion 24 above the protrusion 37. When the support plate 3 is rotated by a tool or the like, for example, the hanging portion 21 is made of resin, the projection 37 is displaced in a direction away from the notch 38 so that the engagement can be released. Yes.
[0026]
Thus, when the protrusion 37 enters the notch 38, the rotation of the support plate 3 is restricted even if a repeated load or vibration is applied in the normal use state of the panel 4, and the support plate 3 is lowered. Does not loosen against the panel retainer 6. On the other hand, when adjusting the height of the bottom plate 5, such as when several panels 4 are placed on the bottom plate 5, the orientation of the bottom plate 5 is kept constant and the support plate 3 is also raised or lowered. Since the base plate 5 can be used as it is, only the support plate 3 can be rotated, so that there is no problem. The standard adjustment of the height of the floor plate 5 by turning the support plate 3 is performed at a position where the protrusion 37 and the notch 38 coincide with each other. There is no worry that you do not know the position. However, it can also be confirmed visually by the window 39 formed in the mounting portion 24 above the protrusion 37.
[0027]
In this case, in order to improve reliability, the engagement structure 36 is preferably provided at a plurality of locations. Specifically, a plurality of protrusions 37 and cutouts 38 are provided, and when one protrusion 37 is fitted into a specific cutout 38, the other protrusions 37 are also fitted into other cutouts 38. It is preferable to adjust the phase to. In this example, six notches 38 are provided at intervals of 60 °, and two protrusions 37 are provided at intervals of 180 °. Of course, this is not particular.
[0028]
FIG. 6 is a plan view of the main part (B portion of FIG. 5) showing another example of the notch 38. In this case, the inclining surface 38a of the notch 38 moves in the direction in which the support plate 3 rises. It is a gentle one that positively allows forced rotation, and is steep in the descending direction as in the previous embodiment. Thereby, the rotation of the support plate 3 in the downward direction in the normal use state of the panel 4 is restricted in the same manner as in the above embodiment. On the other hand, when trying to adjust the height of the base plate 5, when trying to raise the support plate 3 while keeping the orientation of the base plate 5 constant, such as when several panels 4 are placed on the base plate 5 Only the support plate 3 can be turned with a lighter operating force than in the previous embodiment. Of course, when the support plate 3 is forced to be lowered by a tool or the like, it can be performed in the same manner as in the previous embodiment. Further, although not shown in the drawings, the above engagement structure 36 may be formed on the overlapping surface of the support plate 3 and the floor plate 5.
[0029]
Furthermore, it is conceivable that the panel presser 6 is loosened with respect to the support plate 3 alone. Therefore, in the present invention, a loosening prevention structure 42 is provided between the panel retainer 6 and the floor plate 5. The loosening prevention structure 42 of this example forms a number of protrusions 43 on the inner periphery of the through hole 18 of the floor plate 5 (FIGS. 8 and 9), and the protrusions 43 are formed on the outer periphery of the main body portion 26 of the panel retainer 6. A groove 44 that can enter is formed (FIGS. 12 and 13).
[0030]
In this case, the concave portions 45 are formed on both sides of the protrusion 43 so that it can be deformed when the outer periphery of the main body portion 26 passes therethrough to reduce the resistance during the tightening operation on the male screw body 8. The screwing end position of the panel retainer 6 is preferably a position where the projection 43 and the groove 44 coincide with each other, but may be in the middle. In this case, when the panel retainer 6 is loosened, one of the protrusions 43 and the groove 44 are matched, and the further loosening is pawled. In this sense, it is preferable to provide a plurality of protrusions 43 and grooves 44 in phase.
[0031]
【The invention's effect】
As described above, according to the present invention, the support plate and the base plate are engaged with each other by the engagement structure, and this engagement structure allows the support plate to be forcibly rotated with respect to the base plate by a tool or the like. Since rotation in use is restricted, the support plate will not loosen even if a repeated load is applied to the panel, and there will be a gap between the floor plate and the panel, resulting in rattling or noise. It is possible to avoid the occurrence of occurrence and unevenness on the floor surface. On the other hand, when adjusting the height, etc., the operation of forcibly turning the support plate up and down with a tool or the like while placing the panel and keeping the laying plate in a certain direction is even to remove one panel. If you do, you can do without any trouble.
[0032]
In this case, providing a plurality of engagement structures increases the reliability. Furthermore, if a loosening prevention means for preventing loosening of the panel presser is provided, the panel will not be rattled or beep due to looseness of the panel presser.
