Description

【０００１】
【発明の属する技術分野】
この発明は、床下に配線・配管材等の収容空間を形成するための床材を支持する支持脚の取付部材、その床材の支持装置、その床材を支持する支持脚の取付方法、および床材の支持構造に関するものである。
【０００２】
【従来の技術】
従来、床下に配線・配管材等の収容空間を形成するために、床材を所定高さに支持する構造として、例えば、図６に示すようなものがあった。ここで、符号２１は、床材、２２は、その床材２１が載せられる根太材、２３は、その根太材２２と嵌合する受け部材、２４は、その受け部材２３に上部がねじ込まれる支持脚である。こうして、支持脚２４は、それら根太材２２および受け部材２３を介して床材２１、２１を支持する。そして、２５は、その支持脚２４を基礎床面２６に取り付ける取付部材としての台座である。この台座２５は、基礎床面２６に固着される平板状の固着部２５ａと、その固着部２５ａに立設されて、上方にのみ開口し、下方が閉ざされた保持筒２５ｂとからなる。そして、この保持筒２５ｂに、上方より支持脚２４が挿入される。
【０００３】
【発明が解決しようとする課題】
このような従来の床材の支持構造においては、図７および図８に示すように、基礎床面２６に、凹凸や傾斜（不陸）があり、支持脚２４の直下において台座２５の下面２５ｃと基礎床面２６との間に隙間があると、床上の載置物（図示せず）の荷重Ｗにより、支持脚２４が降下して、台座２５の固着部２５ａが前記隙間をなくすように変形する虞があった。そして、この台座２５の変形により、根太材２２および床材２１、２１が沈み込み、床材２１、２１の支持状態に問題があった。また、台座２５を、接着剤を用いて基礎床面２６に固着させる場合、予め、台座２５の固着部２５ａの下面２５ｃまたは基礎床面２６に接着剤を塗布して、その台座２５を基礎床面２６に所定のピッチで載置するとともに、支持脚２４、受け部材２３および根太材２２を組み付ける。このとき、施工時の誤差や各部材の公差等により、根太材２２の位置が若干ずれるのが通常であり、この場合、根太材２２に床材２１、２１を載置することができないので、支持脚２４の位置調整を、接着剤の塗布後、その接着剤が硬化するまでの間の短時間に行う必要があった。また、施工の際、基礎床面２６に墨付する場合は、その墨付された基準ラインに、台座２５の保持筒２５ｂの中心を合わせるようにしてその支持脚２４を立脚する必要があるが、その合わせは、目測に頼らざるを得なかった。
【０００４】
この発明は、上記した従来の欠点を解決するためになされたものであり、その目的とするところは、基礎床面に不陸があっても、床上の載置物の荷重により根太材、床材等が沈み込むことがなく、また、台座等の取付部材を基礎床面に接着する場合は、支持脚の位置調整を、取付部材あるいは基礎床面に接着剤を塗布した後、その接着剤が硬化するまでの間にあわてて行うような取り扱いの不便さがなく、また、基礎床面上の基準ラインに合うように容易に支持脚を立脚することができる、床材を支持する支持脚の取付部材、床材の支持装置、床材を支持する支持脚の取付方法、および床材の支持構造を提供することにある。
【０００５】
【課題を解決するための手段】
この発明に係る床材を支持する支持脚の取付部材、床材の支持装置、床材を支持する支持脚の取付方法、および床材の支持構造は、前記目的を達成するために、次の構成からなる。すなわち、
請求項１に記載の発明に係る支持脚の取付部材は、床下に配線・配管材等の収容空間を形成すベく、基礎床面に立脚されて前記床を形成する床材を所定高さに支持する支持脚を、前記基礎床面に取り付けるためのものである。そして、その取付部材は、前記基礎床面に固着される固着部と、前記支持脚が固定される固定部と、前記支持脚を前記基礎床面に当接させるべく、前記支持脚が、その下端が前記固着部の下面の高さよりも下方に突出する位置から少なくともその下端が前記固着部の下面の高さと一致する位置まで、相対的に上下に真直ぐ移動自在に貫通する貫通部とを備える。これにより、基礎床面に、凹凸や傾斜（不陸）があっても、取付部材の貫通部を貫通した支持脚の下端を取付部材の固着部の下面の高さよりも下方に突出させて、支持脚を基礎床面に当接させることができる。したがって、床上の載置物の荷重は、支持脚から直接基礎床面に作用することとなるので、従来の技術と異なり、支持脚が降下する虞がない。また、取付部材の固着部を基礎床面に接着剤を用いて固着させる場合は、取付部材を、支持脚の下端がその固着部の下面の高さよりも下方に突出するよう、上方に移動させれば、支持脚を基礎床面に立脚させて、施工時の誤差や各部材の公差等による支持脚の立脚位置のずれを修正するための位置調整を行い、その後に、取付部材の固着部の下面または、基礎床面に接着剤を塗布することができる。その後、取付部材を下ろせば、塗布した接着剤によって取付部材の固着部は、基礎床面に固着され、このとき、基礎床面の凹凸や傾斜（不陸）は、塗布した接着剤によって吸収される。また、施工の際、基礎床面に墨付した場合は、支持脚の下端を固着部の下面の高さよりも相対的に下方に突出させることで、その支持脚の下端を墨付された基準ラインに合わせることができる。
【０００６】
また、請求項２に記載の発明に係る支持脚の取付部材のように、前記固定部は、筒状に形成されて前記支持脚が挿入される保持筒からなり、その保持筒の筒孔が、前記貫通部となってもよい。これにより、固定部に貫通部が備わるので、構造が単純化される。
【０００７】
また、請求項３に記載の発明に係る床材の支持装置は、請求項１に記載の取付部材と、支持脚とからなり、請求項１と同様の作用を備える。
【０００８】
また、請求項４に記載の発明に係る床材を支持する支持脚の取付方法は、床下に配線・配管材等の収容空間を形成すベく、基礎床面に立脚されて前記床を形成する床材を所定高さに支持する支持脚を、取付部材を介して前記基礎床面に取り付ける方法である。ここで、前記取付部材は、前記基礎床面に固着される固着部と、前記支持脚が、その下端が前記固着部の下面の高さよりも下方に突出する位置から少なくともその下端が前記固着部の下面の高さと一致する位置まで、相対的に移動自在に貫通する貫通部とを備える。この取付方法は、前記取付部材の貫通部に、前記支持脚を、その下端が前記固着部の下面の高さよりも下方に突出するよう貫通させるとともに、その支持脚を基礎床面に立脚させて所要の位置に位置調整する。その後、前記取付部材を下ろしてその取付部材の前記固着部を前記基礎床面に固着させる。これにより、基礎床面に、凹凸や傾斜（不陸）があっても、支持脚の下端を固着部の下面の高さよりも下方に突出させて、支持脚を基礎床面に当接させることができる。したがって、床上の載置物の荷重は、支持脚から直接基礎床面に作用することとなるので、従来の技術と異なり、支持脚が降下する虞がない。そして、取付部材の固着部を基礎床面に接着剤を用いて固着させる場合は、取付部材の貫通部に、前記支持脚を、その下端が前記固着部の下面の高さよりも下方に突出するよう貫通させるとともに、その支持脚を基礎床面に立脚させて、施工時の誤差や各部材の公差等による支持脚の立脚位置のずれを修正するための位置調整を行うことで、支持脚を基礎床面に立脚させたまま、さらには、支持脚の位置調整後に、取付部材の固着部の下面または、基礎床面に接着剤を塗布することができる。その後、取付部材を下ろせば、塗布した接着剤によって取付部材の固着部は、基礎床面に固着され、このとき、基礎床面の凹凸や傾斜（不陸）は、塗布した接着剤によって吸収される。また、施工の際、基礎床面に墨付した場合は、支持脚の下端を固着部の下面の高さよりも下方に突出するよう貫通させることで、その支持脚の下端を墨付された基準ラインに合わせることができる。
また、請求項５に記載の発明に係る床材の支持構造は、支持脚と取付部材とからなる支持装置を用いた、床材の支持構造である。ここにおいて、支持脚は、床下に配線・配管材等の収容空間を形成すベく、基礎床面に立脚されて前記床を形成する床材を所定高さに支持する。そして、取付部材は、前記支持脚を前記基礎床面に取り付けるための取付部材であって、前記基礎床面に固着される固着部と、前記支持脚が固定される固定部と、前記支持脚が、その下端が前記固着部の下面の高さよりも下方に突出する位置から少なくともその下端が前記固着部の下面の高さと一致する位置まで、相対的に上下に真直ぐ移動自在に貫通する貫通部とを備える。そこで、床材の支持構造にあっては、前記取付部材は、その固着部が前記基礎床面に固着され、かつ、前記支持脚は、前記貫通部を貫通し、その下端が前記基礎床面に当接するようにして、前記固定部に固定されている。こうして、支持脚が基礎床面に当接することで、基礎床面に、凹凸や傾斜（不陸）があっても、床上の載置物の荷重は、支持脚から直接基礎床面に作用することとなるので、従来の技術と異なり、支持脚が降下する虞がない。また、取付部材の固着部を基礎床面に接着剤を用いて固着させる場合は、取付部材を、支持脚の下端がその固着部の下面の高さよりも下方に突出するよう、上方に移動させれば、支持脚を基礎床面に立脚させて、施工時の誤差や各部材の公差等による支持脚の立脚位置のずれを修正するための位置調整を行い、その後に、取付部材の固着部の下面または、基礎床面に接着剤を塗布することができる。その後、取付部材を下ろせば、塗布した接着剤によって取付部材の固着部は、基礎床面に固着され、このとき、基礎床面の凹凸や傾斜（不陸）は、塗布した接着剤によって吸収される。また、施工の際、基礎床面に墨付した場合は、支持脚の下端を固着部の下面の高さよりも相対的に下方に突出させることで、その支持脚の下端を墨付された基準ラインに合わせることができる。
【０００９】
【発明の実施の形態】
以下、この発明の実施の形態を、図面に基づいて説明する。
【００１０】
図１ないし図４は、本発明を根太式タイプの床構造に適用した第一の実施の形態を示す。図中符号、１は、基礎床面、２は、床を形成する床材である。３は、床下に配線・配管材等の収容空間Ｓを形成するために、基礎床面１に立脚されて、根太材４および受け部材５を介して、前記床材２を所定高さに支持する支持脚である。６は、その支持脚３を、基礎床面１に取り付けるための取付部材である。
【００１１】
ここで、根太材４は、例えば、アルミニウム合金を押出成形して得られる型材からなり、断面略逆Ｕ字状からなる本体部４ａと、その本体部４ａから上方に鉛直に延びるように型材の長手方向全てに渡って併設され、それぞれに床材２、２が載置される第１の突条部４ｂ、４ｂと、本体部４ａの両側面から、それぞれ側方に突出して、断面略Ｌ字形状からなる第２の突条部４ｃ、４ｃとから構成されている。根太材４の本体部４ａには、その側部片４ｄ、４ｄの内側に、受け部材５の後述の係合突起５ａと係合する係合凹部４ｅが型材の長手方向全てに渡って形成されている。さらに、根太材４の本体部４ａには、その上部片４ｆの、併設された第１の突条部４ｂ、４ｂに挟まれた部分には、その長手方向の適宜個所に、長孔４ｇ、４ｇが穿設されている。
【００１２】
受け部材５は、根太材４の下方から挿入されて、その本体部４ａの内側に嵌合するよう、その根太材４の長手方向に沿って長く延びる略直方体形状をしている。そして、受け部材５の四隅には、上部から折れ曲がって下方に延びるように弾性片５ｂ、５ｂが形成されており、その弾性片５ｂには、外向きに、根太材４の係合凹部４ｅと係合して抜け止めされる係合突起５ａが形成されている。そして、これら弾性片５ｂ、５ｂは、その弾性力に抗して、内側に撓ませることにより、係合突起５ａと係合凹部４ｅとの係合が解除されて、受け部材５を根太材４から取り外すことができるようになっている。受け部材５の上面には、その長手方向に沿って並ぶように二つの突起５ｃ、５ｃが形成されており、根太材４の長孔４ｇの両端部分に嵌まることにより、根太材４の長手方向に対して受け部材５が位置決めされるようになっている。また、受け部材５の中央内部には、ナット５ｄが、そのナット５ｄのネジ孔５ｅが上下方向を向くように挿入されており、さらに、そのナット５ｄのネジ孔５ｅは、受け部材５の上下面に開口している。
【００１３】
支持脚３は、例えば、円柱状に形成され、その全周にネジ３ａが螺設されたボルト部材からなり、上端には、この支持脚を回すためのマイナス形状の溝３ｂが形成されている。そして、この支持脚３は、その上部が受け部材５のナット５ｄのネジ孔５ｅと螺合し、さらには、受け部材５を根太材４に組み付けたとき、支持脚３の上端が根太材４の長孔４ｇを貫通するようになっている。
【００１４】
取付部材６は、基礎床面１に固着される固着部６ａと、支持脚３が固定される固定部としての保持筒６ｂとが、例えば、圧延鋼板等を絞り加工することにより一体に形成されている。固着部６ａは、略四角形状で平板状に形成されており、その上面には、その中心と同心にリング状に突出する段部６ｃが形成されており、その段部の下面側は、リング状の凹溝６ｄとなっている。そして、固着部６ａには、その段部６ｃに、複数の孔６ｅ、６ｅが穿設されており、さらに、段部６ｃの外側にもまた、固着部６ａの四隅に当たる位置に、孔６ｆ、６ｆが穿設されている。一方、保持筒６ｂは、固着部６ａの中央から上方に突出するように円筒状に形成されている。そして、支持脚３が保持筒６ｂに上方より挿入されるよう、保持筒６ｂの筒孔６ｇは、上方に開口している。さらに、保持筒６ｂの筒孔６ｇは、下方にも開口しており、前記支持脚３が、その下端３ｃが固着部６ａの下面６ｈの高さよりも下方に突出する位置から少なくともその下端３ｃが固着部６ａの下面６ｈの高さと一致する位置まで、相対的に移動自在に貫通する貫通部となっている。さらに、この実施の形態においては、支持脚３は、その下端３ｃが、保持筒６ｂの筒孔６ｇ内を、固着部６ａの下面６ｈの高さよりも下方に突出する位置から固着部６ａの下面６ｈの高さよりも上方に引込む位置まで、相対的に移動自在となっている。そして、保持筒６ｂの上端付近には、外周から内部に貫通するように孔６ｉが穿設されており、その孔６ｉと同心状に、保持筒６ｂの外周側に溶接ナット７が、その溶接ナット７のメネジ部７ａが保持筒６ｂの筒孔６ｇの軸心方向に対して交差する方向に貫通することとなるよう、溶接されて取り付けられている。さらに、その溶接ナット７のメネジ部７ａに螺合して、先端が、保持筒６ｂの筒孔６ｇに挿入される支持脚３に当接可能な、止めネジ８が設けられている。
【００１５】
次に、この支持脚３を、取付部材６を介して基礎床面１に取り付ける取付方法を詳細に説明する。まず、取付部材６の筒孔６ｇに、支持脚３を、その下端３ｃが固着部６ａの下面６ｈの高さよりも下方に突出するよう貫通させる。このとき、止めネジ８を締め込めば、その止めネジ８の先端が支持脚３の周面に当接して、取付部材６は、この状態で、支持脚３に保持される。そして、この支持脚３を受け部材５を介して複数、根太材４の所定箇所に組み付ける（図３参照）。そして、基礎床面１に墨付された基準ラインに合わせて、支持脚３を基礎床面１に立脚させる。さらに、床材２、２が根太材４に正確に載置できるよう、支持脚３を所要の位置に最終的に位置調整するとともに、根太材４のレベル出しを行う。ここで、根太材４のレベル出し、つまり根太材４の上下方向の調整は、根太材４の長孔４ｇを貫通する支持脚３の上端の溝３ｂにマイナスドライバー等の工具を差し込んでその支持脚３を回動することにより行う。このように、支持脚３を基礎床面１の所要の位置に立脚し、その後、取付部材６の固着部６ａの下面６ｈまたは、基礎床面１に接着剤Ｚを塗布する。そして、止めネジ８を緩めて、取付部材６を下ろし、その取付部材６の固着部６ａを基礎床面１に接着剤Ｚにより固着させる。その後、止めネジ８を締め込み、支持脚３を取付部材６に固定する（図１および図５参照）。こうして、支持脚３は、取付部材６を介して基礎床面１に取り付けられる。
【００１６】
支持脚３を基礎床面１に立脚するとき、図１に明示するように、基礎床面１に、凹凸や傾斜（不陸）があっても、支持脚３の下端３ｃを固着部６ａの下面６ｈの高さよりも下方に突出させて、支持脚３を基礎床面１に当接させることができる。したがって、床上の載置物（図示せず）の荷重Ｗは、支持脚３から直接基礎床面１に作用することとなるので、従来の技術と異なり、支持脚３が降下する虞がなく、よって、根太材４および床材２、２が沈み込むことがない。さらに、基礎床面１に、凹凸や傾斜（不陸）がある場合、特に、傾斜がある場合は、従来の技術においては、取付部材（台座）の一部が基礎床面に当接するのみであり（図８参照）、支持脚の立脚が困難であるが、この発明においては、取付部材６の他に支持脚３の下端３ｃが基礎床面１に当接することとなるので、支持脚３の立脚が容易となる（図１参照）。そして、取付部材６の固着部６ａを基礎床面１に接着剤Ｚを用いて固着させるとき、取付部材６の筒孔６ｇに、支持脚３を、その下端３ｃが取付部材６の固着部６ａの下面６ｈの高さよりも下方に突出するよう貫通させるとともに、その支持脚３を基礎床面１に立脚させて、施工時の誤差や各部材の公差等による支持脚３の立脚位置のずれを修正するための位置調整を行うことで、支持脚３を基礎床面１に立脚させたまま、さらには、支持脚３の位置調整後に、取付部材６の固着部６ａの下面６ｈまたは、基礎床面１に接着剤Ｚを塗布することができる。その後、取付部材６を下ろせば、塗布した接着剤Ｚによって取付部材６の固着部６ａは基礎床面１に固着され、このとき、基礎床面１の凹凸や傾斜（不陸）は、塗布した接着剤Ｚによって吸収される。したがって、既述した従来技術とは異なり、支持脚３の位置調整を接着剤の塗布後、その接着剤が硬化するまでの間にあわてて行う必要がない。また、施工の際、基礎床面１に墨付した基準ラインに合わせるとき、支持脚３の下端３ｃを固着部６ａの下面６ｈの高さよりも下方に突出するよう貫通させることで、その支持脚３の下端３ｃを基準ラインに合わせることができるので、その合わせが容易となる。
【００１７】
また、固定部としての保持筒６ｂに、貫通部としての筒孔６ｇが備わるので、貫通部を別途設ける必要がなく、構造が単純化される。また、保持筒６ｂに挿入される支持脚３は、止めネジ８を締め付けることにより、その止めネジ８の先端に押さえつけられて、取付部材６に強固に固定される。
【００１８】
図５は、本発明をフリーアクセスタイプの床構造に適用した第二の実施の形態を示す。このフリーアクセスタイプは、根太式タイプのような床材が根太材に沿って並べられるものではなく、床材のコーナー部がポイント的に支持されるものである。この第二の実施の形態においては、第一の実施の形態における根太材４の代わりに、床材１１のコーナー部が載置される載置部材１２が用いられる。この載置部材１２は、例えば、円盤状に形成されており、その中央には、ネジ孔５ｅが穿設されている。また、支持脚３および取付部材６は、第一の実施の形態のそれと同様である。そして、第一の実施の形態における受け部材５は使用されず、支持脚３は、載置部材１２のネジ孔１２ａに直接ねじ込まれる。このように、フリーアクセスタイプにおいても、根太式タイプと同様の、支持脚３および取付部材６を使用することができ、第一の実施の形態と同様に取り付けられ、同様の作用効果を奏する。
【００１９】
なお、本発明は、上述した実施の形態に限定されるわけではなく、その他種々の変更が可能である。例えば、取付部材６を基礎床面１に固着するのに接着剤を使用しなくとも、取付部材６の固着部６ａに穿設された孔６ｆ、６ｆを利用して、ネジ止めまたは釘打ちにより基礎床面１に固着するものであってもよい。当然ながら、接着剤とネジ止め等を併用して、基礎床面１に固着するものであってもよい。また、支持脚３を取付部材６に固定するのに、止めネジ８を使用しなくとも、接着剤を使用してもよい。さらには、支持脚３を取付部材６に固定するのに、支持脚３と取付部材６の保持筒６ｂの筒孔６ｇとの間にガタ付きがなければ、支持脚３を保持筒６ｂの筒孔６ｇに挿入するだけで、その支持脚３は、前後左右に動かないように固定される。また、支持脚３は、その全周にネジ３ａが螺設されなくとも、第一の実施の形態における受け部材５のネジ孔５ｅまたは、第二の実施の形態における載置部材１２のネジ孔１２ａに螺合する上部のみにネジが螺設されてもよい。また、支持脚３を基礎床面１に立脚させる際、支持脚３の下端３ｃが取付部材６の固着部６ａの下面６ｈの高さよりも下方に突出させた状態を、止めネジ８を締め込むことにより保持させたが、止めネジ８を締め込まなくとも、取付部材６のみを手で持ち上げるようにして、取付部材６の固着部６ａの下面６ｈまたは、基礎床面１に接着剤を塗布してもよい。
【００２０】
【発明の効果】
以上、詳述したところから明らかなように、この発明に係る床材を支持する支持脚の取付部材、床材の支持装置、床材を支持する支持脚の取付方法、および床材の支持構造によれば、次の効果がある。
【００２１】
請求項１に記載された床材を支持する支持脚の取付部材、請求項３に記載された床材の支持装置、請求項４に記載された床材を支持する支持脚の取付方法、そして、請求項５に記載された床材の支持構造によれば、基礎床面が不陸であっても、支持脚が降下する虞がないので床上の載置物の荷重により根太材、床材等が沈み込むことがない。そして、取付部材を基礎床面に接着する場合は、支持脚を基礎床面に立脚させて位置調整した後に接着剤を塗布できるので、その支持脚の位置調整を塗布した接着剤が硬化するまでの間にあわてて行うような、取り扱いの不便さはない。さらに、施工の際、基礎床面に墨付した場合は、支持脚の下端を基礎床面上の墨付された基準ラインに容易に合わせて載置することができる。
【００２２】
また、請求項２に記載された床材を支持する支持脚の取付部材によれば、構造を単純化させることができる。

Here, reference numeral 21 is a floor material, 22 is a joist member on which the floor material 21 is placed, 23 is a receiving member fitted to the joist member 22, and 24 is a support whose upper part is screwed into the receiving member 23. It is a leg. Thus, the support legs 24 support the floor materials 21 and 21 via the joists 22 and the receiving members 23. Reference numeral 25 denotes a pedestal as an attachment member for attaching the support leg 24 to the foundation floor surface 26. The pedestal 25 is composed of a flat plate-like fixing portion 25a fixed to the foundation floor 26, and a holding cylinder 25b that is erected on the fixing portion 25a and that opens only upward and is closed downward. The support leg 24 is inserted into the holding cylinder 25b from above.
[0003]
[Problems to be solved by the invention]
In such a conventional floor material support structure, as shown in FIGS. 7 and 8, the foundation floor surface 26 has irregularities and slopes (unevenness), and the lower surface 25 c of the pedestal 25 just below the support legs 24. If there is a gap between the floor 26 and the foundation floor 26, the support leg 24 is lowered by the load W of the object (not shown) on the floor, and the fixing portion 25a of the base 25 is deformed so as to eliminate the gap. There was a fear. Then, due to the deformation of the pedestal 25, the joist material 22 and the floor materials 21, 21 sink, and there is a problem in the support state of the floor materials 21, 21. Further, when the pedestal 25 is fixed to the foundation floor surface 26 using an adhesive, an adhesive is applied in advance to the lower surface 25c of the fixing portion 25a of the pedestal 25 or the foundation floor surface 26, and the pedestal 25 is fixed to the foundation floor surface. While being mounted on the surface 26 at a predetermined pitch, the support leg 24, the receiving member 23 and the joist member 22 are assembled. At this time, it is normal that the position of the joist member 22 is slightly deviated due to errors in construction, tolerance of each member, etc. In this case, since the floor members 21 and 21 cannot be placed on the joist member 22, It was necessary to adjust the position of the support legs 24 in a short time after the adhesive was applied and until the adhesive was cured. In addition, when marking the foundation floor 26 during construction, it is necessary to stand the supporting leg 24 so that the center of the holding cylinder 25b of the base 25 is aligned with the marked reference line. The alignment had to rely on eye measurements.
[0004]
The present invention has been made in order to solve the above-described conventional drawbacks. The object of the present invention is to provide a joist and flooring material by the load of the object placed on the floor even if the foundation floor surface is uneven. If the mounting member such as a pedestal is bonded to the foundation floor surface, adjust the position of the support legs, apply the adhesive to the mounting member or the foundation floor surface, and then the adhesive Installation of support legs that support the flooring so that there is no inconvenience in handling that occurs until it hardens, and the support legs can be easily erected to meet the reference line on the foundation floor surface. An object is to provide a member, a floor material support device , a method of attaching a support leg to support the floor material, and a floor material support structure .
[0005]

[0015]
Next, the attachment method which attaches this support leg 3 to the foundation floor 1 via the attachment member 6 is demonstrated in detail. First, the support leg 3 is passed through the cylindrical hole 6g of the attachment member 6 so that the lower end 3c protrudes below the height of the lower surface 6h of the fixing portion 6a. At this time, if the set screw 8 is tightened, the tip of the set screw 8 comes into contact with the peripheral surface of the support leg 3, and the mounting member 6 is held by the support leg 3 in this state. And this support leg 3 is assembled | attached to the predetermined location of multiple joists 4 via the receiving member 5 (refer FIG. 3). Then, the support leg 3 is made to stand on the foundation floor surface 1 in accordance with a reference line marked on the foundation floor surface 1.

Here, the leveling of the joist member 4, that is, the adjustment of the joist member 4 in the vertical direction, is performed by inserting a tool such as a screwdriver into the groove 3b at the upper end of the support leg 3 passing through the long hole 4g of the joist member 4. This is done by rotating the leg 3. Thus, the support leg 3 is erected at a required position on the foundation floor surface 1, and then the adhesive Z is applied to the lower surface 6 h of the fixing portion 6 a of the attachment member 6 or the foundation floor surface 1. Then, the set screw 8 is loosened, the mounting member 6 is lowered, and the fixing portion 6a of the mounting member 6 is fixed to the foundation floor surface 1 with the adhesive Z. Thereafter, the set screw 8 is tightened to fix the support leg 3 to the mounting member 6 (see FIGS. 1 and 5). Thus, the support leg 3 is attached to the foundation floor 1 via the attachment member 6.
[0016]
When standing the supporting Jiashi 3 underlying floor surface 1, as best shown in FIG. 1, the basic floor 1, irregularities and slope even (not land) is, the lower end 3c of the support leg 3 fixed portion 6a The support legs 3 can be brought into contact with the foundation floor 1 by projecting downward from the height of the lower surface 6h of the base. Therefore, since the load W of the object (not shown) on the floor acts directly on the foundation floor 1 from the support leg 3, unlike the conventional technique, there is no possibility that the support leg 3 is lowered. The joist 4 and the flooring 2 and 2 do not sink. Furthermore, when the foundation floor surface 1 is uneven or inclined (uneven), particularly when there is an inclination, in the conventional technology, only a part of the mounting member (pedestal) comes into contact with the foundation floor surface. Yes (see FIG. 8), it is difficult to stand the support leg. However, in the present invention, the lower end 3c of the support leg 3 abuts against the foundation floor 1 in addition to the mounting member 6. Is easy to stand (see FIG. 1). When the fixing portion 6a of the mounting member 6 is fixed to the foundation floor 1 using the adhesive Z, the support leg 3 is placed in the cylindrical hole 6g of the mounting member 6, and the lower end 3c thereof is the fixing portion 6a of the mounting member 6. The support leg 3 is made to stand below the height of the lower surface 6h, and the support leg 3 is made to stand on the foundation floor surface 1, so that the deviation of the position of the support leg 3 due to errors in construction, tolerance of each member, etc. By adjusting the position for correction, the lower surface 6h of the fixing portion 6a of the mounting member 6 or the base floor is maintained while the support leg 3 is standing on the base floor surface 1 and further after the position of the support leg 3 is adjusted. Adhesive Z can be applied to surface 1. Thereafter, when the mounting member 6 is lowered, the fixing portion 6a of the mounting member 6 is fixed to the foundation floor surface 1 by the applied adhesive Z. At this time, the unevenness and the inclination (unevenness) of the foundation floor surface 1 are applied. Absorbed by adhesive Z. Therefore, unlike the prior art described above, it is not necessary to adjust the position of the support leg 3 after the adhesive is applied until the adhesive is cured. In addition, when the base line 1 is matched with the reference line marked on the foundation floor 1 at the time of construction, the lower end 3c of the support leg 3 is penetrated so as to protrude downward from the height of the lower surface 6h of the fixing portion 6a. Since the lower end 3c can be aligned with the reference line, the alignment becomes easy.
[0017]
Further, since the holding cylinder 6b as the fixing portion is provided with the cylinder hole 6g as the penetration portion, it is not necessary to separately provide the penetration portion, and the structure is simplified. Further, the support leg 3 inserted into the holding cylinder 6 b is pressed against the tip of the set screw 8 by tightening the set screw 8, and is firmly fixed to the mounting member 6.
[0018]
Figure 5 shows a second embodiment according to the present onset bright free access type of the floor structure. In this free access type, the floor material like the joist type is not arranged along the joist material, but the corner portion of the floor material is supported in a point manner. In the second embodiment, a placement member 12 on which the corner portion of the flooring 11 is placed is used instead of the joist 4 in the first embodiment. The mounting member 12 is formed in a disk shape, for example, and a screw hole 5e is formed in the center thereof. Moreover, the support leg 3 and the attachment member 6 are the same as that of 1st embodiment. And the receiving member 5 in 1st embodiment is not used, but the support leg 3 is directly screwed in the screw hole 12a of the mounting member 12. FIG. Thus, also in the free access type, the support leg 3 and the attachment member 6 similar to the joist type can be used, and they are attached in the same manner as in the first embodiment, and have the same operational effects.
[0019]
In addition, this invention is not necessarily limited to embodiment mentioned above, A various other change is possible. For example, even if an adhesive is not used to fix the mounting member 6 to the foundation floor surface 1, the holes 6 f and 6 f drilled in the fixing portion 6 a of the mounting member 6 are used for screwing or nailing. It may be fixed to the foundation floor 1. Needless to say, the adhesive may be fixed to the foundation floor 1 by using an adhesive and screwing together. Further, an adhesive may be used to fix the support leg 3 to the mounting member 6 without using the set screw 8. Furthermore, when the support leg 3 is fixed to the mounting member 6, if there is no backlash between the support leg 3 and the cylindrical hole 6 g of the holding cylinder 6 b of the mounting member 6, the support leg 3 is fixed to the cylinder of the holding cylinder 6 b. The support leg 3 is fixed so as not to move back and forth and left and right simply by being inserted into the hole 6g. Further, the support leg 3 has the screw hole 5e of the receiving member 5 in the first embodiment or the screw hole of the mounting member 12 in the second embodiment, even if the screw 3a is not screwed around the entire circumference. A screw may be screwed only in the upper part screwed to 12a. Further, when the support leg 3 is made to stand on the foundation floor surface 1, the set screw 8 is tightened so that the lower end 3 c of the support leg 3 protrudes below the height of the lower surface 6 h of the fixing portion 6 a of the mounting member 6. Even if the set screw 8 is not tightened, the adhesive is applied to the lower surface 6h of the fixing portion 6a of the mounting member 6 or the foundation floor 1 so that only the mounting member 6 is lifted by hand. May be.
