Description

【０００１】
【発明の属する技術分野】
本願発明は、床スラブのような床基面の上に間隔をあけてフロアパネルを敷設して二重床構造とするときに、このフロアパネルを支持するフロアパネル支持装置に関するものである。
【０００２】
【従来の技術】
従来から、この種のフロアパネル支持装置として、特開２０００−８７５３７号公報に示される「支柱の構造」が知られている。この「支柱の構造」は、図８に示す如く、床スラブのような床基面１４の上に間隔をあけてフロアパネル４を敷設して二重床構造とするときに、このフロアパネル４を支持するものである。そして、この「支柱の構造」は、ベース部１にボルト部２を立設して形成される支持基体３と、この支持基体３のボルト部２に螺合されてフロアパネル４を高さ位置調整自在に支持する支持受け体５と、同ボルト部２に螺合されてこの支持受け体５をその下側から当止することで保持固定する緩み止め固定体６と、を備えている。
【０００３】
この場合、緩み止め固定体６は、図９に示す如く、前記ボルト部２に螺合される螺合基部７と、この螺合基部７から変形部８を介して外側方へ延設される操作片部９と、を有しており、ここでは、二つの操作片部９が同螺合基部７の両側へ対称に延設されている。又、緩み止め固定体６は金属板材で形成され、雌ねじ孔１０を設けてなる螺合基部７と、この螺合基部７から同金属板材の長手方向に沿って両外側方へ延設される各操作片部９と、の間に介設される両変形部８が、巾狭となったくびれ状に形成されて、各変形部８の両縁側部分には切り込み状部１１が存在しており、両変形部８では塑性変形され易くなっている。
【０００４】
そして、フロアパネル４が所定の高さ位置で支持されるように高さ位置調整された後の支持受け体５に対して、その下側から緩み止め固定体６を螺合回動させて締め付け、同支持受け体５に当止させてこれを保持固定するものである。その際、緩み止め固定体６はその操作片部９に外力が加えられて回動操作されるものであり、一定以上の外力を加えると、同操作片部９は変形部８を基点として折れ曲がるように変形するものである。これにより、支持受け体５が既にロックされたものであるか否かを目視によって確認することができ、又、この場合、緩み止め固定体６を水平に回動させてその締め付け作業が行われるので、低床であっても作業し易く、同緩み止め固定体６を緩めて再度調整することも可能となる。

【０００６】
【発明が解決しようとする課題】
しかしながら、上記従来の技術にあっては、支持受け体５が既にロックされたものであるか否かを目視によって確認することはできても、緩み止め固定体６の締め付け度合いが適切であるか否かを目視によって判断することはできないものであった。すなわち、緩み止め固定体６を回動させて締め付ける際に、どの程度まで締め付ければ良いかという基準が不明確で、締め付けトルクに差を生じ、支持固定の確実性に関して施工バラツキを発生するものであった。
【０００７】
この場合、一定以上の外力によって操作片部９が変形するので、変形するまで同操作片部９に外力を加えて、緩み止め固定体６を回動させ締め付ければ良いものではあるが、変形するまでといってもその変形度合いはまちまちで、どの程度変形すれば所定の締め付けトルクで締め付けられたことになるかを、個々の作業者が判断することは困難で基準という面でも問題があった。
【０００８】
そこで、操作片部９の曲げ変形量をゲージで測定して、所定の締め付けトルクで締め付けられたことを確認する作業を行うこともあったが、施工現場で多数の対象についてゲージ測定で確認するという作業は、極めて困難で手間のかかる作業となっていた。又、施工者に対し施工説明書等で、操作片部９が所定の角度に折れ曲がるまで締め付け作業を行う旨の説明を行うこともあったが、この場合には、所定の角度という基準が不明確で目視によっては確認し難く、施工バラツキが依然として発生するものであった。
【０００９】
本願発明は、上記従来の技術に鑑みて発明されたものであり、その課題は、フロアパネルを支持する支持受け体が適切に保持固定されていることを、目視によって簡単かつ確実に判断することのできるフロアパネル支持装置を提供することである。
【００１０】
【課題を解決するための手段】
上記課題を解決するために、本願発明のフロアパネル支持装置では、ベース部にボルト部を立設して形成される支持基体と、この支持基体のボルト部に螺合されてフロアパネルを高さ位置調整自在に支持する支持受け体と、同ボルト部に螺合されてこの支持受け体をその下側から当止することで保持固定する緩み止め固定体と、を備え、緩み止め固定体は、ボルト部に螺合される螺合基部と、この螺合基部から変形部を介して外側方へ延設される操作片部と、を有しており、変形部が塑性変形することで螺合基部に対して操作片部が所定角度折曲変形されたことを表示する変形目安手段を、同緩み止め固定体に設けてなる構成としたものである。
【００１１】
したがって、この場合、緩み止め固定体をその操作片部に外力を加えて回動操作することにより、フロアパネルを所定高さで支持する支持受け体は、その下側から同緩み止め固定体が当止することで保持固定される。その際、支持受け体が適切に保持固定される程度に緩み止め固定体が螺合回動され締め付けられた段階で、同緩み止め固定体の変形部は塑性変形し、螺合基部に対し前記操作片部が所定角度折曲変形された状態となる。そして、緩み止め固定体に設けられた変形目安手段の表示により、前記変形部が塑性変形して螺合基部に対し操作片部が所定角度折曲変形されたことを目視によって簡単かつ確実に判断することができ、支持固定の確実性に関する施工のバラツキを減少させることができる。
【００１２】
【発明の実施の形態】
図１〜４は、本願請求項１〜４、７に対応した第一の実施形態であるフロアパネル支持装置を示している。この実施形態のフロアパネル支持装置は、図１、４に示す如く、ベース部１にボルト部２を立設して形成される支持基体３と、この支持基体３のボルト部２に螺合されてフロアパネル４を高さ位置調整自在に支持する支持受け体５と、同ボルト部２に螺合されてこの支持受け体５をその下側から当止することで保持固定する緩み止め固定体６と、を備えている。
【００１３】
そして、図２に示す如く、緩み止め固定体６は、前記ボルト部２に螺合される螺合基部７と、この螺合基部７から変形部８を介して外側方へ延設される操作片部９と、を有しており、変形部８が塑性変形することで螺合基部７に対して操作片部９が所定角度α折曲変形されたことを表示する変形目安手段Ａを、同緩み止め固定体６に設けた構成となっている。この場合には、緩み止め固定体６の両側に変形目安手段Ａが配設されている。
【００１４】
又、この実施形態のフロアパネル支持装置では、緩み止め固定体６を略長方形状の金属板材で形成し、雌ねじ孔１０を設けてなる螺合基部７と、この螺合基部７から同金属板材の長手方向に沿って外側方へ延設される操作片部９と、の間に介設される変形部８を、巾狭となったくびれ状に形成している。なお、操作片部９は、上記従来の技術のものと同様に、螺合基部７の両外側方へ対称に延設されてもよい。
【００１５】
この場合に、くびれ状に形成された変形部８の両側縁部分に存在する各切り込み状部１１の切り込み開口付近において、同切り込み状部１１の相対向する一方の側縁部分に凸片部１２を突設し、この凸片部１２が他方の側縁部分に重なることで、螺合基部７に対して操作片部９が所定角度α折曲変形されたことを表示する変形目安手段Ａとしている。ここでは、緩み止め固定体６の板厚分程度に凸片部１２を上方へ切り起こして形成し、この凸片部１２を切り込み状部１１の対向する他方の側縁部分の上側で重なるように突設してもいる。
【００１６】
そして、この実施形態のフロアパネル支持装置では、緩み止め固定体６を支持受け体５に当止させてこれを保持固定するのに最低限必要となる締め付けトルクに達した段階で、螺合基部７に対して操作片部９が所定角度α折曲変形された状態となるものである。
【００１７】
以下、この実施形態のフロアパネル支持装置を、より具体的に説明する。このフロアパネル支持装置全体では、図１、４に示す如く、支持基体３と支持受け体５と緩み止め固定体６とが主体構成となる。支持基体３はベース部１とその中央に立設されるボルト部２とでなり、このボルト部２の下端が同ベース部１に対して回動自在に装着されている。ベース部１の周縁部分には、コンクリートスラブ等の床下地となる床基面１４に固定するための複数の取付用孔１５が配置穿設されている。ボルト部２の外周にはその上下略全長にわたって雄ねじ２ａが設けられ、支持受け体５の中央部分で上下に貫通する筒状スペースの内周には雌ねじ５ａが設けられている。
【００１８】
そして、前記支持受け体５の雌ねじ５ａがボルト部２の雄ねじ２ａに螺合されることで、この支持受け体５は同ボルト部２に対し相対的に螺合回動して上下動高さ位置調整自在に装着されている。支持受け体５の四方上面にはクッションゴム１６が装着されており、各クッションゴム１６の間で同支持受け体５の四角部分にはパネル固定孔１８が配置穿設されている。又、支持受け体５中央の前記筒状スペースの上端開口部分には、その内周の雌ねじ５ａに螺合されることでキャップ１７が着脱自在に装着されている。
【００１９】
この場合、前記支持受け体５の四角部分上にフロアーパネル４の角部分が各々設置され、四方に配置されることになるフロアーパネル４の角部分の上端縁フランジ部分がその両側のクッションゴム１６上に載置され、この各角部分は同支持受け体５の前記パネル固定孔１８を用いて固定される。この固定状態にあっても、各フロアーパネル４の角部分間の中央では、支持受け体５中央の前記筒状スペースの上端開口部分が上方へ突出しており、前記キャップ１７を外して、同上端開口部分からその内部の前記ボルト部２の上端部分（操作され得る形状となっている）をレンチ等の工具で回動操作することにより、同支持受け体５を上下螺合動作させることができる。ここでは、ボルト部２が床基面１４上に設置固定されているベース部１に対して回動し、支持受け体５はそれ自体が回動することなくフロアーパネル４を支持したままで上下螺合動作される。
【００２０】
緩み止め固定体６は、前記支持受け体５が上下螺合動作することを阻止するものである。すなわち、図２に示す如く、緩み止め固定体６はその全体が略長方形状の金属板材で形成され、この金属板材の一端側に形成されて雌ねじ孔１０を有する螺合基部７と、同金属板材の他端側に延設形成される操作片部９と、この螺合基部７と操作片部９との間で同金属板材が巾狭となったくびれ状に形成されることで介設される変形部８と、でその主体は構成されている。変形部８が巾狭となったくびれ状に形成されることで、緩み止め固定体６の中程両側には同変形部８の側縁部分で切り込み状部１１が形成されることになる。なお、この場合、緩み止め固定体６の片側のみに切り込み状部１１が形成されるだけでも、変形部８は巾狭となったくびれ状となり得るものである。
【００２１】
緩み止め固定体６の螺合基部７では、図１（ｃ）、図４に示す如く、同螺合基部７部位の金属板材の下側にナット１９をカシメ、溶接等で固着することにより雌ねじ孔１０を形成している。この場合、ナット１９をレンチ等の工具で回動操作することによっても、緩み止め固定体６を緩めたり締め付けたりすることができ、操作片部９が誤って変形し過ぎたり破損したとき等の通常でない際にも対応可能となり、同ナット１９を回動操作して再度調整作業を行うこともできる。なお、螺合基部７部位の金属板材にバーリング加工を施して、このバーリング加工された筒状突出部分の内部を雌ねじ孔１０として直接に形成してもよい。
【００２２】
そして、図２（ａ）に示す如く、前記緩み止め固定体６の変形部８両側の切り込み状部１１の各切り込み開口部分では、同切り込み状部１１の螺合基部７側の側縁部分から凸片部１２が一体に突出形成されている。この場合、図２（ｃ）に示す如く、凸片部１２は緩み止め固定体６の板厚分程度に上方へ切り起こし形成され、切り込み状部１１の対向する操作片部９側の側縁部分の上側で重なるように突設されている。又、図２（ｂ）に示す如く、操作片部９に外力が加えられて螺合基部７が螺合回動され、変形部８が塑性変形して同操作片部９が所定角度α折曲変形された状態において、前記凸片部１２の先端は切り込み状部１１の対向する操作片部９側の側縁部分の上側に重なり、この段階で、緩み止め固定体６を支持受け体５に対して締め付け固定するために必要な最低限の締め付けトルクが得られる。
【００２３】
すなわち、図２（ａ）に示す如く、操作片部９が折曲変形されていない緩み止め固定体６の当初形態で、前記凸片部１２の先端とこれに対向する切り込み状部１１の側縁部分との間隔寸法Ｗが、前記最低限必要となる締め付けトルクを確保するための最小限の曲げ巾寸法として設定されている。又、この場合、凸片部１２の先端が切り込み状部１１の対向する側縁部分の上側に重なった段階で最低限必要な締め付けトルクが得られ、必要に応じてより以上に操作片部９を折曲変形させて更なる締め付けトルクを得ることもでき、その際、最終的には同凸片部１２の切り起こし基端部分が対向する側縁部分に当止することで、同操作片部９の不必要で無理な折曲変形は防止される。
【００２４】
これにより、所定範囲内の適切な締め付けトルクで緩み止め固定体６による締め付け固定作業は行われ、操作片部９の変形し過ぎや破損も防止されて、この操作片部９を操作して再度調整作業を行うことができる。なお、前記凸片部１２の重なりによって表示する変形目安手段Ａは緩み止め固定体６の両側に配設されており、この緩み止め固定体６が表裏反対に装着された際にも、他方の変形目安手段Ａを用いることで対応可能となっているが、その際には、凸片部１２が切り込み状部１１の対向する側縁部分の下側に重なることになり、作業者はこれを上方から目視し難いものである。
【００２５】
それ故、緩み止め固定体６の螺合基部７の雌ねじ孔１０とボルト部２の雄ねじ２ａとの螺合関係（右ねじか左ねじかであるが通常は右ねじ）によって締め付け回動方向は決定されることから、この回動方向へと操作片部９が折曲変形される側で対応するように、変形目安手段Ａは同緩み止め固定体６の片側にのみ設けられてもよい。この場合、緩み止め固定体６の装着状態における表裏（上下）面が決定され、その螺合回動方向も操作し易い方向に設定されて、この操作に支障を来すことはない。
【００２６】
又、この実施形態のフロアパネル支持装置では、図３に示す如く、上操作具２０と下操作具２１とを用いて締め付け作業を楽に行うことができる。すなわち、上操作具２０の先端部分には嵌合部２０ａが形成されており、この嵌合部２０ａを支持受け体５にその上側から嵌合し、下操作具２１の先端部分を緩み止め固定体６の操作片部９に差し込むように嵌合する。そして、この状態で、上操作具２０と下操作具２１とを相反する方向へ回動させるように操作することにより、緩み止め固定体６の螺合基部７が支持受け体５に対し締め付けられてその下側に当止され、同支持受け体５を緩み動かないように保持固定する。その後、上記の如く、支持受け体５上にフロアーパネル４が設置されるものであり、その際、図４に示す如く、同フロアーパネル４上にはカーペットのような床仕上げ材２２が敷設されてもよい。
【００２７】
したがって、この実施形態のフロアパネル支持装置においては、緩み止め固定体６をその操作片部９に外力を加えて回動操作することにより、フロアパネル４を所定高さで支持する支持受け体５は、その下側から同緩み止め固定体６の螺合基部７が当止することで保持固定される。その際、支持受け体５が適切に保持固定される程度に緩み止め固定体６が螺合回動され締め付けられた段階で、すなわち、所定の締め付けトルクに達した段階で、同緩み止め固定体６の変形部８は塑性変形し、螺合基部７に対して前記操作片部９が所定角度α折曲変形された状態となる。
【００２８】
そして、緩み止め固定体６に設けられた変形目安手段Ａの表示により、前記変形部８が塑性変形して螺合基部７に対し操作片部９が所定角度α折曲変形されたことを、作業者は目視によって簡単かつ確実に判断することができ、支持固定の確実性に関する施工のバラツキは減少される。しかも、外側方に延設される操作片部９を操作することにより、緩み止め固定体６を水平に回動させてその締め付け作業が行われるので、二重床構造が低床であっても作業し易く、同緩み止め固定体６を緩めて同様に再度調整することもできる。
【００２９】
又、この実施形態のフロアパネル支持装置においては、緩み止め固定体６が略長方形状の金属板材で形成され、その螺合基部７と操作片部９との間に介設される変形部８は巾狭となったくびれ状に形成されているので、この変形部８が塑性変形し易いのに対して、その両側の螺合基部７及び操作片部９がその各々では塑性変形し難くなり、この両者の相互位置関係で表示することになる変形目安手段Ａの表示精度が向上される。
【００３０】
又、この実施形態のフロアパネル支持装置においては、前記変形部８の両側縁部分に存在することになる切り込み状部１１の切り込み開口付近で、同切り込み状部１１の相対向する一方の側縁部分に凸片部１２が突設されている。そして、変形目安手段Ａは、前記凸片部１２が切り込み状部１１の対向する他方の側縁部分に重なることにより表示するものであるため、螺合基部７に対して操作片部９が所定角度α折曲変形されたことを、作業者は同凸片部１２の重なった状態を目視確認して容易に判断することができる。
【００３１】
しかも、この場合、緩み止め固定体６の板厚分程度に、前記凸片部１２は上方へ切り起こして形成され、この凸片部１２が切り込み状部１１の対向する他方の側縁部分の上側で重なるように突設されているので、同凸片部１２は対向する他方の側縁部分に当止しないようスムーズに重なり、この重なった状態を上方から作業者がより目視確認し易くなって、変形目安手段Ａの表示精度は更に向上される。
【００３２】
そして、この実施形態のフロアパネル支持装置においては、緩み止め固定体６を支持受け体５に当止させてこれを保持固定するのに最低限必要となる締め付けトルクに達した段階で、螺合基部７に対して操作片部９が所定角度α折曲変形された状態となるので、これを表示する変形目安手段Ａの表示に基づいて締め付け作業を行えば、最低限の締め付けトルクによる支持受け体５の保持固定強度は確保され、必要に応じてそれ以上の締め付けトルクで締め付け作業を行うこともできる。
【００３３】
図５は、本願請求項１〜４、７に対応した第二の実施形態であるフロアパネル支持装置を示している。この実施形態のフロアパネル支持装置では、緩み止め固定体６の変形部８の両側縁部分に存在する両切り込み状部１１の各切り込み開口部分において、同切り込み状部１１の操作片部９側の側縁部分に凸片部１２が突設されており、この凸片部１２は同切り込み状部１１の対向する螺合基部７側の側縁部分の上側に重なるものである。なお、それ以外は、上記第一の実施形態と同様に構成され、上記第一の実施形態におけると同様の作用効果が奏される。
【００３４】
図６は、本願請求項１、２、５〜７に対応した第三の実施形態であるフロアパネル支持装置を示している。この実施形態のフロアパネル支持装置では、緩み止め固定体６の螺合基部７及び操作片部９の各表面に、螺合基部７に対して操作片部９が所定角度α折曲変形された状態で、変形部８の略中心を通る一直線Ｌ上で並ぶように表示マーク１３ａ、１３ｂを配設し、この両表示マーク１３ａ、１３ｂを変形目安手段Ａとして設けている。
【００３５】
この場合、変形目安手段Ａとなる両表示マーク１３ａ、１３ｂを、螺合基部７に対して操作片部９が所定角度α折曲変形された状態で、変形部８の略中心を通る一直線Ｌ上に沿う線状のマークとしている。又、螺合基部７側に設けられる表示マーク１３ａが同螺合基部７及び操作片部９に連続する中心線Ｍの両側に対にして配設されており、操作片部９側に設けられる表示マーク１３ｂは同中心線Ｍ上に一つだけ設けられている。
【００３６】
そして、図６（ａ）に示す如く、緩み止め固定体６の無変形状態では、両表示マーク１３ａと表示マーク１３ｂとがいずれも相互に傾斜した表示形態となり、図６（ｂ）に示す如く、操作片部９が所定角度α折曲変形された緩み止め固定体６の変形状態では、両表示マーク１３ａのいずれか一方と表示マーク１３ｂとが前記中心線Ｍに対して角度αだけ傾斜する前記一直線Ｌ上で直線的に並んだ表示形態となる。両表示マーク１３ａ、１３ｂが一直線Ｌ上で並んだ状態で、最低限必要となる締め付けトルクにより操作片部９は所定角度α折曲変形されているが、必要に応じてそれ以上の締め付けトルクで締め付け作業を行うこともできる。
【００３７】
又、この実施形態にあっても、螺合基部７の雌ねじ孔１０での螺合形態によって締め付け回動方向は決定されることから、この回動方向へと操作片部９が折曲変形された際に、同操作片部９の表示マーク１３ｂと一直線Ｌ上で並ぶ一方の表示マーク１３ａだけを設けて、変形目安手段Ａを単一のものとしてもよい。又、各表示マーク１３ａ、１３ｂは、金属板材でなる緩み止め固定体６に対し刻印を施すことで容易に形成されているが、塗装や印刷或いはテープを貼着することによっても容易に形成されるものである。
【００３８】
したがって、この実施形態のフロアパネル支持装置において、変形目安手段Ａは緩み止め固定体６の螺合基部７及び操作片部９の各表面に配設される表示マーク１３ａ、１３ｂでなり、この両表示マーク１３ａ、１３ｂが変形部８の略中心を通る一直線Ｌ上で並んだ状態を表示するものであるため、螺合基部７に対して操作片部９が所定角度α折曲変形されたことを、作業者は両表示マーク１３ａ、１３ｂの前記一直線Ｌ上に並んだ状態を目視確認して容易に判断することができる。
【００３９】
しかも、この場合、変形目安手段Ａとなる両表示マーク１３ａ、１３ｂを、螺合基部７に対して操作片部９が所定角度α折曲変形された状態で、変形部８の略中心を通る一直線Ｌ上に沿う線状のマークとしているので、同状態では線状の両表示マーク１３ａ、１３ｂが相互に傾斜することなく直線的に配列されて、作業者はこの両線状のマークの直線的な配列状態を表面側からより目視確認し易くなり、変形目安手段Ａの表示精度が更に向上される。
【００４０】
なお、それ以外は、上記第一の実施形態と同様に構成され、上記第一の実施形態におけると同様の作用効果が奏される。又、この実施形態において変形目安手段Ａとなる両表示マーク１３ａ、１３ｂを、上記第一、第二の実施形態のフロアパネル支持装置において同様に配設することもでき、この場合には、二種類の変形目安手段Ａが配設されることになって、作業者の目視による判断はより簡単かつ確実なものとなり、支持固定の確実性に関する施工バラツキが更に減少される。
【００４１】
図７は、本願請求項１、２、５〜７に対応した第四の実施形態であるフロアパネル支持装置を示している。この実施形態のフロアパネル支持装置では、操作片部９側に設けられる表示マーク１３ｂが螺合基部７及び同操作片部９に連続する中心線Ｍの両側に対にして配設されており、螺合基部７側に設けられる表示マーク１３ａは同中心線Ｍ上に一つだけ設けられている。なお、それ以外は、上記第三の実施形態と同様に構成され、上記第三の実施形態におけると同様の作用効果が奏される。
【００４２】
又、上記各実施形態においては、緩み止め固定体６として板状のものを示したが、本願発明における緩み止め固定体６は、例えば、棒状やブロック状のものであってもよく、このような場合には、変形部８を小径或いは薄肉状とすることで形成することができる。又、本願発明における変形目安手段Ａとしては、凸片部１２や表示マーク１３によるものだけでなく、例えば、ブロック状の螺合基部７から棒状の操作片部９を小径となる変形部８を介し結合突設して緩み止め固定体６を形成し、その際、同操作片部９をその回動操作方向と反対側に予め所定角度だけ傾斜するように突設しておいて、この操作片部９が締め付け作業の外力により変形部８の塑性変形に伴って折曲変形し、同螺合基部７から傾斜なく真っ直ぐ突出する状態となった段階で、同操作片部９は所定角度折曲変形され、変形目安手段Ａが前記操作片部９の真っ直ぐ突出した状態を表示するものであってもよい。
【００４３】
【発明の効果】
本願請求項１記載のフロアパネル支持装置においては、緩み止め固定体の変形部が塑性変形して操作片部は螺合基部に対し所定角度折曲変形され、この状態でフロアパネルを支持する支持受け体が適切な強度で保持固定されているものであり、この適切に保持固定されていることを、同緩み止め固定体に設けられた変形目安手段による表示を目視することで簡単かつ確実に判断することができ、支持固定の確実性に関する施工バラツキも減少される。
【００４４】
本願請求項２記載のフロアパネル支持装置においては、特に、金属板材で形成された緩み止め固定体の螺合基部と操作片部との間に位置する変形部が、巾狭となったくびれ状に形成されて、この変形部は塑性変形し易く、その両側の螺合基部及び操作片部がその各々では塑性変形し難くなり、この両者の相互位置関係で表示することになる変形目安手段の表示精度が向上される。
【００４５】
本願請求項３記載のフロアパネル支持装置においては、特に、変形部の側縁部分に存在する切り込み状部の切り込み開口付近で、相対向する一方の側縁部分に凸片部が突設され、この凸片部が他方の側縁部分に重なることによって、変形目安手段は表示するものであり、作業者は同表示を目視確認して操作片部が所定角度折曲変形されたことを容易に判断することができる。
【００４６】
本願請求項４記載のフロアパネル支持装置においては、特に、凸片部が緩み止め固定体の板厚分程度に上方へ切り起こし形成されて、切り込み状部の対向する他方の側縁部分の上側にスムーズに重なり、この重なった状態を上方から作業者はより目視確認し易くなって、変形目安手段の表示精度が更に向上される。
【００４７】
本願請求項５記載のフロアパネル支持装置においては、特に、緩み止め固定体の螺合基部及び操作片部の各表面に配設される両表示マークが変形目安手段となって、この変形目安手段は両表示マークが変形部の略中心を通る一直線上で並んだ状態を表示するものであり、作業者は同表示を目視確認して操作片部が所定角度折曲変形されたことを容易に判断することができる。
【００４８】

[Prior art]
2. Description of the Related Art As a floor panel support device of this type, a “post structure” disclosed in JP-A-2000-87537 has been conventionally known. As shown in FIG. 8, this "support structure" is used when the floor panels 4 are laid at intervals on a floor base surface 14 such as a floor slab to form a double floor structure. It is to support. The “strut structure” includes a support base 3 formed by erecting a bolt portion 2 on a base portion 1 and a floor panel 4 screwed to the bolt portion 2 of the support base 3 so that the floor panel 4 is at a height position. There is provided a support receiving member 5 that supports an adjustable manner, and a locking member 6 that is screwed into the bolt portion 2 and holds and fixes the support receiving member 5 by abutting the support receiving member 5 from below.
[0003]
In this case, as shown in FIG. 9, the loosening prevention fixed body 6 extends outward from the screw base 7 via the deformable portion 8 and the screw base 7 screwed to the bolt portion 2. And an operation piece 9, wherein two operation pieces 9 are symmetrically extended to both sides of the screw base 7. Further, the locking member 6 is formed of a metal plate, and is provided with a screw base 7 having a female screw hole 10 and extends from the screw base 7 to both outsides along the longitudinal direction of the metal plate. The two deformed portions 8 interposed between the respective operation piece portions 9 are formed in a narrowed narrow shape, and the cut-shaped portions 11 are present at both edges of each deformed portion 8. Therefore, both the deformed portions 8 are easily plastically deformed.

[Problems to be solved by the invention]
However, in the above-described conventional technique, it is possible to visually check whether or not the support receiver 5 is already locked, but whether the degree of tightening of the locking stopper 6 is appropriate. It was not possible to judge visually whether or not it was. That is, when rotating and fixing the locking member 6, the standard of how much to tighten the screw is unclear, a difference occurs in the tightening torque, and a variation occurs in the reliability of the support fixing. Met.
[0007]
In this case, since the operation piece 9 is deformed by an external force exceeding a certain level, the external force may be applied to the operation piece 9 until the operation piece 9 is deformed, and the locking member 6 may be rotated and tightened. Even so, the degree of deformation varies, and it is difficult for each worker to judge how much deformation is required to achieve the specified tightening torque. Was.
[0008]
Therefore, the bending deformation of the operation piece 9 was measured with a gauge to confirm that the operation piece 9 was tightened with a predetermined tightening torque. However, many objects were checked at the construction site by gauge measurement. Was extremely difficult and time-consuming. In some cases, the installer is instructed in a construction manual or the like to perform the tightening operation until the operation piece 9 is bent to a predetermined angle, but in this case, the standard of the predetermined angle is not satisfied. It was clear and difficult to confirm by visual inspection, and construction variation still occurred.
[0009]
SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned conventional technology, and an object of the present invention is to visually and simply determine that a support receiver that supports a floor panel is appropriately held and fixed. It is to provide a floor panel support device that can be used.
[0010]
[Means for Solving the Problems]
In order to solve the above problems, a floor panel support device of the present invention has a support base formed by erecting a bolt portion on a base portion, and a floor panel which is screwed to the bolt portion of the support base to raise the height of the floor panel. A support receiving body that supports the position thereof freely adjustable, and a locking stopper fixed by being screwed to the bolt portion and holding and fixing the supporting receiver from below the locking receiver. A screw base that is screwed into the bolt part, and an operation piece that extends outward from the screw base through the deformation part, and the screw is formed by plastic deformation of the deformation part. Deformation guide means for indicating that the operation piece has been bent at a predetermined angle with respect to the joint base is provided on the loosening prevention fixed body.
[0011]
Therefore, in this case, the support member for supporting the floor panel at a predetermined height by rotating the locking member by applying an external force to the operation piece portion of the locking member has the locking member fixed from below. It is held and fixed by stopping. At this time, at the stage where the locking stopper is screwed and rotated and tightened to such an extent that the support receiver is appropriately held and fixed, the deformed portion of the locking stopper is plastically deformed, and the above-described locking base is deformed relative to the screw base. The operation piece is bent at a predetermined angle. Then, the indication of the deformation guide means provided on the anti-loosening fixing body makes it possible to visually and easily judge that the deformed portion is plastically deformed and the operation piece is bent at a predetermined angle with respect to the screw base. It is possible to reduce the variation in the construction relating to the reliability of the support fixing.
[0012]
BEST MODE FOR CARRYING OUT THE INVENTION
1 to 4 show a floor panel support device according to a first embodiment corresponding to claims 1 to 4 and 7 of the present application. As shown in FIGS. 1 and 4, the floor panel support device of this embodiment is provided with a support base 3 formed by erecting a bolt section 2 on a base section 1 and screwed to the bolt section 2 of the support base 3. Support member 5 for supporting the floor panel 4 in a height-adjustable manner, and an anti-loosening fixed body screwed into the bolt portion 2 and holding and fixing the support receiver 5 by abutting it from below. 6 is provided.
[0013]
Then, as shown in FIG. 2, the loosening prevention fixed body 6 includes a screw base 7 screwed to the bolt portion 2, and an operation extending outward from the screw base 7 via the deformation portion 8. And a deformation guide means A for indicating that the operation piece 9 has been bent at a predetermined angle α with respect to the screw base 7 by plastically deforming the deformation portion 8, The structure is provided on the loosening prevention fixed body 6. In this case, deformation guide means A are provided on both sides of the locking member 6.
[0014]
Further, in the floor panel support device of this embodiment, the locking stopper 6 is formed of a substantially rectangular metal plate material, and a screw base 7 having a female screw hole 10 is provided. And a deformable portion 8 interposed between the operation piece portion 9 extending outwardly along the longitudinal direction of the main body, and a narrow portion having a narrow width. The operation piece 9 may be symmetrically extended to both outer sides of the screw base 7 in the same manner as in the above-mentioned prior art.
[0015]
In this case, in the vicinity of the notch opening of each notch 11 existing on both side edges of the deformed portion 8 formed in a constricted shape, a convex piece 12 is formed on one of the opposing side edges of the notch 11. The projection piece 12 is overlapped with the other side edge portion, and as a deformation guide means A for indicating that the operation piece 9 has been bent at a predetermined angle α with respect to the screw base 7. I have. Here, the protruding piece 12 is formed by cutting and raising upward about the plate thickness of the loosening prevention fixed body 6, and the protruding piece 12 is overlapped on the other side edge portion of the cut-shaped portion 11 opposite to the other side edge portion. There are also protruding.
[0016]
In the floor panel support device of this embodiment, when the tightening torque required to stop the loosening fixing body 6 against the support receiving body 5 and hold and fix the fixing receiving body 6 has been reached, the threaded base portion is set. 7, the operation piece 9 is bent at a predetermined angle α.
[0017]
Hereinafter, the floor panel support device of this embodiment will be described more specifically. As shown in FIGS. 1 and 4, the entire floor panel support device mainly includes a support base 3, a support receiving member 5, and a fixing member 6 for preventing loosening. The support base 3 includes a base 1 and a bolt 2 erected at the center thereof. The lower end of the bolt 2 is rotatably mounted on the base 1. A plurality of mounting holes 15 for fixing to a floor base surface 14 serving as a floor foundation of a concrete slab or the like are provided in the peripheral portion of the base portion 1. A male screw 2a is provided on the outer periphery of the bolt portion 2 over substantially the entire vertical direction, and a female screw 5a is provided on the inner periphery of a cylindrical space vertically penetrating at the center of the support receiver 5.
[0018]
When the female screw 5a of the support receiving member 5 is screwed into the male screw 2a of the bolt portion 2, the supporting receiving member 5 is screwed and rotated relatively to the bolt portion 2 to move up and down. It is mounted so that the position can be adjusted freely. Cushion rubbers 16 are mounted on the four upper surfaces of the support receiver 5, and panel fixing holes 18 are arranged and formed in the square portions of the support receiver 5 between the cushion rubbers 16. A cap 17 is detachably mounted on the upper end opening of the cylindrical space at the center of the support receiver 5 by being screwed into a female screw 5a on the inner periphery thereof.
[0019]
In this case, the corner portions of the floor panel 4 are respectively set on the square portions of the support receiver 5, and the upper end edge flange portions of the corner portions of the floor panel 4 to be arranged in four directions are the cushion rubbers 16 on both sides thereof. Each corner portion is placed on the support receiver 5 and fixed using the panel fixing hole 18. Even in this fixed state, at the center between the corners of each floor panel 4, the upper end opening of the cylindrical space at the center of the support receiver 5 projects upward. By turning the upper end portion (having a shape that can be operated) of the bolt portion 2 inside the opening portion with a tool such as a wrench, the support receiver 5 can be screwed up and down. . Here, the bolt portion 2 is rotated with respect to the base portion 1 installed and fixed on the floor base surface 14, and the support receiver 5 is moved up and down while supporting the floor panel 4 without rotating itself. The screw operation is performed.
[0020]
The locking stopper 6 prevents the support receiver 5 from being screwed up and down. That is, as shown in FIG. 2, the locking stopper 6 is formed entirely of a substantially rectangular metal plate, and is formed at one end of the metal plate with a screw base 7 having a female screw hole 10. An operation piece 9 extending from the other end of the plate is provided, and the metal sheet is formed between the screw base 7 and the operation piece 9 by forming a narrow constricted shape. The main body is constituted by the deformed portion 8 to be formed. Since the deformed portion 8 is formed in a narrow constricted shape, the notch-shaped portion 11 is formed at the side edges of the deformed portion 8 on both sides in the middle of the loosening fixing body 6. In this case, the deformed portion 8 can have a narrow and narrow shape even if the notch-shaped portion 11 is formed only on one side of the locking member 6.
[0021]
As shown in FIGS. 1C and 4, the nut 19 is fixed to the lower portion of the metal plate material at the portion of the screwing base 7 by caulking, welding, or the like. A hole 10 is formed. In this case, by rotating the nut 19 with a tool such as a wrench, the locking member 6 can be loosened or tightened, and the operation piece 9 can be accidentally deformed excessively or damaged. It is possible to cope with an unusual case, and the adjusting operation can be performed again by rotating the nut 19. The metal plate material at the screw base 7 may be subjected to burring, and the inside of the burred cylindrical protrusion may be directly formed as the female screw hole 10.
[0022]
Then, as shown in FIG. 2A, at each of the notch opening portions of the notch portions 11 on both sides of the deformed portion 8 of the loosening fixing body 6, the side edges of the notch portion 11 on the screwing base 7 side are used. The protruding piece 12 is integrally formed so as to protrude. In this case, as shown in FIG. 2 (c), the convex piece 12 is cut and raised upward by the thickness of the locking member 6, and the side edge of the cut piece 11 on the side of the opposing operation piece 9. It protrudes so as to overlap on the upper side of the part. Further, as shown in FIG. 2B, an external force is applied to the operation piece portion 9, the screwing base portion 7 is screwed and rotated, the deformation portion 8 is plastically deformed, and the operation piece portion 9 is folded at a predetermined angle α. In the bent state, the tip of the convex piece 12 overlaps the upper side edge of the cut piece 11 on the side of the opposing operation piece 9, and at this stage, the locking stopper 6 is supported by the support receiver 5. , The minimum tightening torque required for tightening and fixing is obtained.
[0023]
In other words, as shown in FIG. 2 (a), in the initial form of the locking member 6 in which the operation piece 9 is not bent and deformed, the tip of the convex piece 12 and the side of the notch 11 facing the tip. The distance W from the edge portion is set as a minimum bending width dimension for securing the minimum required tightening torque. In this case, the minimum necessary tightening torque is obtained at the stage when the tip of the convex piece 12 overlaps the upper side of the opposing side edge of the cut-shaped part 11, and the operating piece 9 can be further increased as necessary. Can be further deformed to obtain a further tightening torque. At that time, the cut-and-raised base end portion of the convex piece portion 12 finally abuts on the opposing side edge portion. Unnecessary and unnecessary bending deformation of the portion 9 is prevented.
[0024]
As a result, the tightening and fixing operation by the locking member 6 is performed with an appropriate tightening torque within a predetermined range, and the operation piece 9 is prevented from being excessively deformed or damaged, and the operation piece 9 is operated again. Adjustment work can be performed. In addition, the deformation | transformation indication means A displayed by the overlapping of the said convex piece part 12 is arrange | positioned at both sides of the locking member 6, and when this locking member 6 is mounted upside down, the other is fixed. It is possible to cope with this by using the deformation guide means A, but in this case, the convex piece portion 12 overlaps the lower side of the opposed side edge portion of the cut-shaped portion 11, and the operator can change this. It is difficult to see from above.
[0025]
Therefore, the tightening rotation direction is determined by the screwing relationship between the female screw hole 10 of the screwing base 7 of the locking member 6 and the male screw 2a of the bolt portion 2 (whether right-handed or left-handed, but usually right-handed). Since it is determined, the deformation guide means A may be provided only on one side of the locking member 6 so that the operation piece 9 is bent and deformed in this rotation direction. In this case, the front and back (upper and lower) surfaces in the mounted state of the anti-loosening fixed body 6 are determined, and the screwing rotation direction is set to a direction that is easy to operate, so that there is no trouble in this operation.
[0026]
Further, in the floor panel support device of this embodiment, as shown in FIG. 3, the tightening operation can be easily performed using the upper operation tool 20 and the lower operation tool 21. That is, a fitting portion 20a is formed at a distal end portion of the upper operating tool 20, and the fitting portion 20a is fitted into the support receiver 5 from above, and the distal end portion of the lower operating tool 21 is fixed to prevent loosening. It is fitted so as to be inserted into the operation piece 9 of the body 6. Then, in this state, by operating the upper operation tool 20 and the lower operation tool 21 to rotate in opposite directions, the screw base 7 of the loosening prevention fixed body 6 is tightened to the support receiver 5. The support receiver 5 is held and fixed so as not to move loosely. Thereafter, as described above, the floor panel 4 is installed on the support receiver 5, and as shown in FIG. 4, a floor finishing material 22 such as a carpet is laid on the floor panel 4 as shown in FIG. You may.
[0027]
Therefore, in the floor panel support device of this embodiment, the support member 5 for supporting the floor panel 4 at a predetermined height by rotating the locking member 6 by applying an external force to the operation piece 9 thereof. Is held and fixed by the screwing base 7 of the loosening fixing body 6 abutting from below. At this time, at the stage where the locking stopper 6 is screwed and rotated to such an extent that the support receiver 5 is properly held and fixed, that is, at the stage where a predetermined tightening torque is reached, the locking stopper is fixed. The deformed portion 8 of 6 is plastically deformed, and the operation piece 9 is bent at a predetermined angle α with respect to the screw base 7.
[0028]
The indication of the deformation guide means A provided on the loosening prevention fixed body 6 indicates that the deformation portion 8 has been plastically deformed and the operation piece 9 has been bent at a predetermined angle α with respect to the screw base 7. The operator can easily and reliably judge by visual inspection, and the variation in the construction relating to the reliability of the support fixing is reduced. Moreover, by operating the operation piece portion 9 extending outward, the locking member 6 is horizontally rotated to perform the tightening operation, so that even if the double floor structure is a low floor, The work is easy, and the locking member 6 can be loosened and adjusted again.
[0029]
Further, in the floor panel support device of this embodiment, the locking member 6 is formed of a substantially rectangular metal plate, and the deformation portion 8 is provided between the screw base 7 and the operation piece 9. Is formed in a constricted shape with a narrow width, so that the deformed portion 8 is easily plastically deformed, while the screw base 7 and the operation piece 9 on both sides are hardly plastically deformed. The display accuracy of the deformation indicator A, which is displayed based on the mutual positional relationship between the two, is improved.
[0030]
Further, in the floor panel support device of this embodiment, one of the opposing side edges of the cut-shaped portion 11 near the cut opening of the cut-shaped portion 11 to be present on both side edges of the deformed portion 8. A protruding piece 12 protrudes from the portion. In addition, since the deformation guide means A indicates that the convex piece portion 12 overlaps the other side edge portion of the notch-shaped portion 11 opposite to the cut piece portion 11, the operation piece portion 9 is fixed to the screw base 7. The worker can easily determine that the angle α is bent by visually checking the overlapping state of the convex pieces 12.
[0031]
Moreover, in this case, the convex piece 12 is formed by cutting and raising upward about the plate thickness of the loosening prevention fixed body 6, and this convex piece 12 is formed on the other side edge portion of the cut-shaped portion 11 facing the other. Since the projections are provided so as to overlap on the upper side, the convex pieces 12 smoothly overlap so as not to abut on the other side edge portion facing the same, and it becomes easier for an operator to visually confirm the overlapped state from above. Thus, the display accuracy of the deformation indicator A is further improved.
[0032]
In the floor panel support device of this embodiment, when the tightening torque which is the minimum required to cause the locking device 6 to abut on the support receiving member 5 and hold and fix it is screwed, Since the operation piece 9 is bent at a predetermined angle α with respect to the base 7, if the tightening operation is performed based on the display of the deformation guide means A for displaying the operation, the support receiving member with the minimum tightening torque can be used. The holding and fixing strength of the body 5 is ensured, and the tightening operation can be performed with a higher tightening torque if necessary.
[0033]
FIG. 5 shows a floor panel support device according to a second embodiment corresponding to claims 1 to 4 and 7 of the present application. In the floor panel support device of this embodiment, at each of the notch opening portions of both notch portions 11 present on both side edge portions of the deformed portion 8 of the locking member 6, the operation piece portion 9 side of the notch portion 11 is provided. A protruding piece 12 protrudes from the side edge portion, and the protruding piece 12 overlaps the upper side of the side edge portion of the notch-shaped portion 11 on the side of the opposing screw base 7. In other respects, the configuration is the same as that of the first embodiment, and the same operation and effect as those of the first embodiment are exerted.
[0034]
FIG. 6 shows a floor panel support device according to a third embodiment corresponding to claims 1, 2, and 5 to 7 of the present application. In the floor panel support device of this embodiment, the operation piece 9 is bent at a predetermined angle α with respect to the screw base 7 on each surface of the screw base 7 and the operation piece 9 of the locking stopper 6. In this state, the display marks 13a and 13b are arranged so as to be arranged on a straight line L passing substantially the center of the deformed portion 8, and both the display marks 13a and 13b are provided as deformation guide means A.
[0035]
In this case, the two display marks 13a and 13b serving as the deformation guide means A are aligned with a straight line L substantially passing through the center of the deformation portion 8 in a state where the operation piece portion 9 is bent at a predetermined angle α with respect to the screw base 7. It is a linear mark along the top. In addition, the display marks 13a provided on the screw base 7 are arranged in pairs on both sides of a center line M that is continuous with the screw base 7 and the operation piece 9, and are provided on the operation piece 9 side. Only one display mark 13b is provided on the center line M.
[0036]
Then, as shown in FIG. 6 (a), in the non-deformed state of the locking member 6, both the display mark 13a and the display mark 13b are in a mutually inclined display form, as shown in FIG. 6 (b). In the deformed state of the locking member 6 in which the operation piece 9 is bent at the predetermined angle α, one of the two display marks 13a and the display mark 13b are inclined by the angle α with respect to the center line M. The display form is linearly arranged on the straight line L. In a state where the two display marks 13a and 13b are aligned on the straight line L, the operation piece portion 9 is bent at a predetermined angle α by the minimum required tightening torque, but if necessary, the operation piece portion 9 is bent at a higher torque. Tightening work can also be performed.
[0037]
Also in this embodiment, since the tightening and rotating direction is determined by the form of screwing of the screwing base 7 into the female screw hole 10, the operation piece 9 is bent and deformed in this rotating direction. In this case, only one display mark 13a aligned on the straight line L with the display mark 13b of the operation piece portion 9 may be provided, and the deformation guide means A may be a single one. Each of the display marks 13a and 13b is easily formed by engraving the locking stopper 6 made of a metal plate, but can also be easily formed by painting, printing, or attaching a tape. Things.
[0038]
Therefore, in the floor panel support device of this embodiment, the deformation guide means A is composed of the display marks 13a and 13b provided on the surfaces of the screw base 7 and the operation piece 9 of the loosening fixing body 6, respectively. Since the display marks 13a and 13b indicate a state in which the display marks 13a and 13b are arranged on a straight line L passing substantially the center of the deformed portion 8, the operation piece portion 9 is bent at a predetermined angle α with respect to the screw base 7. Can be easily determined by visually checking the state where both display marks 13a and 13b are aligned on the straight line L.
[0039]
In addition, in this case, the two display marks 13a and 13b serving as the deformation guide means A pass through substantially the center of the deformation portion 8 in a state where the operation piece portion 9 is bent at a predetermined angle α with respect to the screw base 7. Since the mark is a linear mark along the straight line L, in the same state, the two linear display marks 13a and 13b are linearly arranged without being inclined with respect to each other, and the operator can straighten the two linear marks. It is easier to visually confirm the proper arrangement state from the front side, and the display accuracy of the deformation indicator A is further improved.
[0040]
In other respects, the configuration is the same as that of the first embodiment, and the same operation and effect as those of the first embodiment are exerted. In addition, the two display marks 13a and 13b serving as the deformation guide means A in this embodiment can be similarly arranged in the floor panel support device of the first and second embodiments. With the provision of the type of deformation guide means A, the visual judgment of the operator becomes simpler and more reliable, and the variation in the construction relating to the reliability of the support fixing is further reduced.
[0041]
FIG. 7 shows a floor panel support device according to a fourth embodiment corresponding to claims 1, 2, 5 to 7 of the present application. In the floor panel support device of this embodiment, the display marks 13b provided on the operation piece 9 side are arranged in pairs on both sides of the screw base 7 and the center line M continuous with the operation piece 9; Only one display mark 13a provided on the screw base 7 side is provided on the center line M. Otherwise, the configuration is the same as in the third embodiment, and the same operation and effect as in the third embodiment are exerted.
[0042]
Further, in each of the above embodiments, the plate-shaped fixing member 6 is shown as the locking member 6, but the locking member 6 in the present invention may be, for example, a rod-shaped or block-shaped member. In such a case, it can be formed by making the deformed portion 8 small or thin. Further, as the deformation guide means A in the present invention, not only the projection piece 12 and the display mark 13 but also a deformation section 8 having a small diameter from the block-shaped screw base 7 to the rod-shaped operation piece 9 is used. The loosening fixing body 6 is formed by protruding through the intermediary portion. At this time, the operation piece portion 9 is protruded from the opposite side to the rotation operation direction so as to be inclined at a predetermined angle in advance, and this operation is performed. At the stage where the piece 9 is bent and deformed due to the plastic deformation of the deformable portion 8 due to the external force of the tightening operation, and comes into a state of projecting straight from the screw base 7 without inclination, the operation piece 9 is bent at a predetermined angle. The operation may be modified so that the operation indicator 9 is displayed in a state in which the operation piece 9 is projected straight.
[0043]
