（３）ドライバー等の回転工具の先端を、床下地材の縁部から露出した支持板の貫通穴に差し込みドライバー用溝に嵌め込んで、脚本体を回転させ該脚本体に対し支持板を上下動させることで、床下地材のレベル（又は支持板の上面位）を調節する。
（４）その隣の床下地材も同様に、一辺を既に設置されている支持脚の上面に、支持板の貫通穴が露出する様に隙間を開けて載せる。
（５）上記（２）と同様に、床スラブ上に所定間隔毎に配置した支持脚の支持板上に、他辺を片持たせの状態で載せると共に、支持板の上面に貼着した粘着シートに圧着して仮固定する。
（６）上記（４）〜（５）を繰り返す。
（７）最終的には（４）の後に、際根太上に床下地材の他辺を載せる。
（８）必要に応じて床面レベルを調整した後、床下地材を支持脚の支持板に釘着し、床下地材を支持脚に固定する。
（９）その後、床下地材に床仕上げ材を敷設する。 And a floor is constructed like the following (1)-(9).
(1) Place one side of the floor base material on the joist when it is provided along a predetermined height of the wall.
(2) On the support plate of the support leg arranged at predetermined intervals on the floor slab, the other side of the floor base material that does not contact the joist is put in a cantilevered state and attached to the upper surface of the support plate. Crimp and temporarily fix to the adhesive sheet.
(3) Insert the tip of a rotating tool such as a screwdriver into the through hole of the support plate exposed from the edge of the floor base material, and insert it into the groove for the driver. By moving, the level of the floor base material (or the upper surface position of the support plate) is adjusted.
(4) Similarly, the next floor base material is placed on the upper surface of the supporting leg already installed with a gap so that the through hole of the supporting plate is exposed.
(5) Similar to the above (2), the adhesive is placed on the support plate of the support leg arranged at predetermined intervals on the floor slab with the other side being cantilevered and adhered to the upper surface of the support plate. Crimp and temporarily fix the sheet.

しかし、上記従来技術にあっては、衝撃を吸収する部分は脚本体の下端側のクッション材だけであることから床振動を吸収しきれず、その結果床スラブ側に大きい振動が作用して、階下に大きい音が伝播してしまうなど、解決せねばならない課題があった。 However, in the above prior art, the only part that absorbs the impact is the cushion material on the lower end side of the leg body, so it cannot absorb floor vibrations, resulting in large vibrations acting on the floor slab side and downstairs There was a problem that had to be solved, such as a loud sound propagating in the room.

本発明は、上記従来技術に基づく、階下に大きい音が伝播してしまう課題に鑑み、２枚の木質板の間に衝撃吸収板を介設した支持板と、該支持板の下方に圧縮バネを介在させて設けた脚体とを有し、該脚体は、外周面にネジ山を設けた脚本体と、内周面にねじ溝を形成して脚本体に螺合した調整筒体とを有し、圧縮バネの下端を調整筒体に、上端を支持板の下面に固定し、支持板における衝撃吸収板と脚体と支持板とを独立させて装備させるための圧縮バネにより確実に振動を吸収することによって、階下へ伝播する音の大きさを確実に抑えることを可能にして、上記課題を解決する。 In view of the problem that a loud sound propagates downstairs based on the above-described conventional technology, the present invention has a support plate in which an impact absorbing plate is interposed between two wooden boards, and a compression spring is interposed below the support plate. The leg body has a leg main body having a thread on the outer peripheral surface, and an adjustment cylinder that is threaded on the inner peripheral surface and screwed into the leg main body. Then, the lower end of the compression spring is fixed to the adjustment cylinder, the upper end is fixed to the lower surface of the support plate, and the vibration is reliably vibrated by the compression spring for mounting the shock absorbing plate, leg and support plate on the support plate independently. By absorbing, it is possible to surely suppress the volume of sound propagating downstairs, thereby solving the above-mentioned problem.

要するに本発明は、２枚の木質板の間に衝撃吸収板を介設した支持板と、該支持板の下方に圧縮バネを介在させて設けた脚体とを有しているので、床材から伝播されてくる振動は、先ず支持板の衝撃吸収板で吸収され、更に圧縮バネで吸収された後に脚体に伝わり、最終的に床スラブに伝播することになるため、階下へ伝播する音をなるべく小さくすることが出来、よって快適な住環境を提供することが出来る。
具体的には、脚体は、外周面にネジ山を設けた脚本体と、内周面にねじ溝を形成して脚本体に螺合した調整筒体とを有し、圧縮バネの下端を調整筒体に、上端を支持板の下面に固定したので、支持板の下面に配した圧縮バネに脚体を固定させて、圧縮バネにより振動を吸収して脚体に伝播させることを実現させることが出来る等その実用的効果甚だ大である。 In short, the present invention has a support plate in which an impact absorbing plate is interposed between two wooden boards, and a leg provided with a compression spring interposed below the support plate. The vibration that is received is first absorbed by the shock absorbing plate of the support plate, further absorbed by the compression spring, and then transmitted to the legs and finally to the floor slab, so that the sound that propagates downstairs is as much as possible. It can be made smaller, thus providing a comfortable living environment.
Specifically, the leg body has a leg main body having a thread on the outer peripheral surface, and an adjustment cylinder body formed with a thread groove on the inner peripheral surface and screwed into the leg main body, and has a lower end of the compression spring. the adjustment cylinder, so fixing the upper to the lower surface of the support plate, by fixing the leg to the compression spring arranged on the lower surface of the support plate, to realize be propagated to the leg to absorb vibration by the compression spring The practical effect is great.

図１〜３は、本発明に係る床材用支持脚の実施例１の正面図、平面図及びＡ−Ａ断面図である。
上記支持板３は、ベニヤ板、パーティクルボードの様な２枚の木質板１、1aの間に、制振、遮音性を有する樹脂系、プラスチック系の衝撃吸収板２が介設されており、かかる支持板３の上面に粘着シート６が貼着され、中央に貫通穴７が形成されている。
上記圧縮バネ４は、上記脚体５が挿設され、且つその下端部が脚体５の中間部に固定されている。
上記脚体５は、外周面にネジ山を設けた脚本体８と、内周面にねじ溝を形成して脚本体８に螺合した調整筒体９とを有し、該調整筒体９に上記圧縮バネ４の下端部が固定され、脚本体８の上端部にドライバー用溝10を形成すると共に、下端部にクッション材11を設けている。更に、脚本体８を管状にして上下方向への貫通孔12を形成すると共に、クッション材11の下面に、貫通孔12が開口する溝13を形成しても良い。
又、脚本体８における調整筒体９の上下部位にロックナット14、14a を螺合するのが好ましい。 1 to 3 are a front view, a plan view, and a cross-sectional view taken along line AA of Embodiment 1 of a floor material support leg according to the present invention.
The supporting plate 3 is provided with a vibration- and sound-insulating resin-based and plastic-based shock absorbing plate 2 between two wood boards 1 and 1a such as a veneer board and a particle board. An adhesive sheet 6 is adhered to the upper surface of the support plate 3 and a through hole 7 is formed at the center.
The compression spring 4 has the leg 5 inserted therein, and the lower end thereof is fixed to the intermediate part of the leg 5.
The leg body 5 includes a leg main body 8 having a thread on the outer peripheral surface, and an adjustment cylinder body 9 formed with a thread groove on the inner peripheral surface and screwed into the leg main body 8. The lower end of the compression spring 4 is fixed to the upper end of the leg main body 8 and a driver groove 10 is formed at the lower end, and a cushioning material 11 is provided at the lower end. Further, the leg main body 8 may be formed in a tubular shape to form the through hole 12 in the vertical direction, and the groove 13 in which the through hole 12 opens may be formed on the lower surface of the cushion material 11.
Further, it is preferable that the lock nuts 14 and 14a are screwed into the upper and lower portions of the adjustment cylinder 9 in the leg body 8.

そして、ドライバー等の回転工具（図示せず）の先端を、支持板３の貫通穴７に差し込み、脚本体８の上端部のドライバー用溝10に嵌め込んで脚本体８を回転させると、該脚本体に対し調整筒体９が上下動し、それに伴い圧縮バネ４及び支持板３も上下動するが、圧縮バネ４は変形しない。 Then, when the tip of a rotary tool (not shown) such as a screwdriver is inserted into the through hole 7 of the support plate 3 and fitted into the driver groove 10 at the upper end of the leg body 8, the leg body 8 is rotated. The adjustment cylinder 9 moves up and down with respect to the leg main body, and the compression spring 4 and the support plate 3 also move up and down accordingly, but the compression spring 4 is not deformed.

次に、本発明に係る床材用支持脚の作用について説明する。
本発明に係る床材用支持脚の使用方法にあっては、上述の従来技術と同じであり、かかる床材用支持脚により構築された床は、支持板３における衝撃吸収板２の制振作用と、脚体５と支持板３とを独立させて装備させるための圧縮バネ４の制振作用とにより確実に振動を吸収し、更に床スラブＳとの接触部位であるクッション材11の制振作用と相俟って、階下へ伝播する音の大きさを確実に抑えられる。 Next, the effect | action of the support leg for flooring which concerns on this invention is demonstrated.
The method of using the floor support legs according to the present invention is the same as the above-described conventional technique, and the floor constructed by the floor support legs is used for damping the shock absorbing plate 2 in the support plate 3. The vibration is reliably absorbed by the action and the damping action of the compression spring 4 for mounting the leg body 5 and the support plate 3 independently, and further, the cushioning material 11 that is the contact portion with the floor slab S is controlled. Combined with the vibration action, the volume of sound propagating downstairs can be reliably suppressed.

又、脚体５の貫通孔12に接着剤を注入し、該貫通孔12を流下して床スラブＳの上面に到達し、クッション材11の溝13を伝わって該クッション材11の外周側へ拡がって、クッション材11を床スラブＳに固定すれば、歩行時等の荷重負荷の際に反動によって床スラブＳから脚体５が離れない。
更に、ロックナット14、14a 、17により、繰り返される歩行等による脚本体８に対する調整筒体９の緩み、外筒体15に対する中筒体16の緩みに伴うレベル調整の狂い、床落ち、床鳴り、床パネル間の段差発生などが発生しない。 Further, an adhesive is injected into the through hole 12 of the leg 5, flows down through the through hole 12, reaches the upper surface of the floor slab S, travels along the groove 13 of the cushion material 11, and moves to the outer peripheral side of the cushion material 11. If it spreads and the cushioning material 11 is fixed to the floor slab S, the leg 5 will not be separated from the floor slab S due to a reaction when a load is applied during walking or the like.
Further, the lock nuts 14, 14 a, 17 cause looseness of the adjustment cylinder 9 with respect to the leg body 8 due to repeated walking, etc., level adjustment error due to loosening of the intermediate cylinder 16 with respect to the outer cylinder 15, floor falling, and floor noise. No level difference between floor panels.
