最良の形態１
図１及び図２は最良の形態１を示し、図１は床下地構造を備えた二重床の断面を示し、図２は床パネル及び支持脚の配置例を上から見て示す。 Best form 1
1 and 2 show the best mode 1, FIG. 1 shows a cross-section of a double floor provided with a floor foundation structure, and FIG. 2 shows an example of the arrangement of floor panels and support legs as seen from above.

図１に示すように、床下地構造１は、床スラブ２に設置された複数の支持脚３と、支持脚３により支持された複数の床パネル４と、補強材１２とにより形成される。床パネル４としては、例えば、長辺の長さ１８２０ｍｍ、短辺の長さ６００ｍｍ、厚さ２０ｍｍの長方形平板状に形成されたボードが使用される。複数の床パネル４が部屋や廊下のような室内５の床レベル面上に並ぶように敷設され、隣り合う床パネル４同士は、端面６同士が隙間ｅを介して離されて配置される。隙間ｅは、１５ｍｍ〜２０ｍｍ程度である。図示しないが端面６同士が互いに接触し合うように配置される場合もある。床スラブ２に設置される支持脚３は、台座３３が、互いに隣り合う各々の床パネル４の下面７に跨るように配置されたり、台座３３が、１つの床パネル４の下面７に位置するように配置される。支持脚３の台座３３と床パネル４とが釘などの固定具によって互いに連結される。複数の支持脚３の設置間隔は、例えば、３００ｍｍ〜６００ｍｍ程度に決められる。   As shown in FIG. 1, the floor foundation structure 1 is formed by a plurality of support legs 3 installed on a floor slab 2, a plurality of floor panels 4 supported by the support legs 3, and a reinforcing material 12. As the floor panel 4, for example, a board formed in a rectangular flat plate shape having a long side length of 1820 mm, a short side length of 600 mm, and a thickness of 20 mm is used. A plurality of floor panels 4 are laid so as to be arranged on the floor level surface of the room 5 such as a room or a corridor, and the adjacent floor panels 4 are arranged with the end surfaces 6 separated from each other via a gap e. The gap e is about 15 mm to 20 mm. Although not shown, the end faces 6 may be arranged so as to contact each other. The support legs 3 installed on the floor slab 2 are arranged so that the pedestals 33 straddle the lower surfaces 7 of the floor panels 4 adjacent to each other, or the pedestals 33 are positioned on the lower surface 7 of one floor panel 4. Are arranged as follows. The pedestal 33 of the support leg 3 and the floor panel 4 are connected to each other by a fixture such as a nail. The installation interval of the plurality of support legs 3 is determined to be about 300 mm to 600 mm, for example.

室内５の壁際に配置される床パネル（以下、壁際床パネルという）４Ａにおける壁面１０に近い部分（以下、壁面近傍部分という）１１の下面７Ａには、補強材１２が取付けられる。補強材１２は、壁面１０に沿った方向に延長するとともに、壁際床パネル４Ａの下面７Ａより床スラブ２に向かって延長するように設けられる。補強材１２は、壁側床パネル４Ａの壁面近傍部分１１の下面７Ａに強固に一体化されるように取付けられる。例えば、補強材１２と壁側床パネル４Ａとが、釘、ビス、ステープル、接着剤のうちの１つあるいは２つ以上の併用によって、互いに強固に一体化するように取付けられる。壁際床パネル４Ａと上記補強材１２とにより、壁際補強床パネルが形成される。図１に示すように、補強材１２は、例えば、壁面１０と向かい合う一方の面１３と壁面１０に対して隙間ａを隔てて配置される壁際床パネル４Ａの壁側端面６Ａとが面一となるように、壁際床パネル４Ａの下面７Ａに取付けられ、壁際床パネル４Ａの下面７Ａと直交する方向に延長する。壁際床パネル４Ａの下面７Ａに取付けられた補強材１２の下端１６と床スラブ２との間には間隔ｂが設けられる。   A reinforcing material 12 is attached to a lower surface 7A of a portion (hereinafter referred to as a wall surface vicinity) 11 near a wall surface 10 in a floor panel (hereinafter referred to as a wall surface floor panel) 4A disposed near the wall of the room 5. The reinforcing material 12 extends in the direction along the wall surface 10 and is provided so as to extend from the lower surface 7A of the wall-side floor panel 4A toward the floor slab 2. The reinforcing member 12 is attached so as to be firmly integrated with the lower surface 7A of the wall surface vicinity portion 11 of the wall side floor panel 4A. For example, the reinforcing member 12 and the wall-side floor panel 4A are attached so as to be firmly integrated with each other by using one or more of nails, screws, staples, and adhesives. A wall-side reinforcing floor panel is formed by the wall-side floor panel 4A and the reinforcing member 12. As shown in FIG. 1, for example, the reinforcing member 12 is flush with a wall 13 on one side 13 facing the wall surface 10 and a wall-side end surface 6A of the wall-side floor panel 4A arranged with a gap a between the wall surface 10. In this way, it is attached to the lower surface 7A of the wall-side floor panel 4A and extends in a direction orthogonal to the lower surface 7A of the wall-side floor panel 4A. A space b is provided between the lower end 16 of the reinforcing member 12 attached to the lower surface 7A of the wall-side floor panel 4A and the floor slab 2.

即ち、補強材１２と床スラブ２とが間隔ｂを隔てて非接触状態となり、かつ、壁際床パネル４Ａの壁側端面６Ａと壁面１０とが隙間ａを隔てて非接触状態となるように、壁側床パネル４Ａの下面７Ａが支持脚３により支持され、補強材１２の下端１６が支持脚３により支持されていない構成とした。
つまり、壁側床パネル４Ａの壁面近傍部分１１に荷重が加わった場合でも、補強材１２の下端１６と床スラブ２とが互いに接触しないように、壁際床パネル４Ａを支持する支持脚３の配置位置や、補強材１２の上下方向に延長する長さｃが設定される。
よって、補強材１２の下端１６が支持脚３により支持されておらず、補強材１２と床スラブ２とが間隔ｂを隔てて非接触状態であるため、壁側床パネル４Ａから補強材１２に伝わる音が床スラブ２に伝わらない。
また、壁際床パネル４Ａの壁側端面６Ａと壁面１０とを隙間ａを隔てて非接触状態としたことで、壁側床パネル４Ａの壁面近傍部分１１に荷重が加わって壁面近傍部分１１が上下に動いたとしても壁側端面６Ａと壁面１０とが擦れあうことが防止されるため、擦れ音の発生を防止できる。 That is, the reinforcing member 12 and the floor slab 2 are in a non-contact state with a gap b, and the wall-side end surface 6A of the wall-side floor panel 4A and the wall surface 10 are in a non-contact state with a gap a. The lower surface 7 </ b> A of the wall-side floor panel 4 </ b> A is supported by the support legs 3, and the lower end 16 of the reinforcing material 12 is not supported by the support legs 3.
That is, even when a load is applied to the wall surface vicinity portion 11 of the wall-side floor panel 4A, the arrangement of the support legs 3 that support the wall-side floor panel 4A so that the lower end 16 of the reinforcing member 12 and the floor slab 2 do not contact each other. The position and the length c extending in the vertical direction of the reinforcing member 12 are set.
Therefore, since the lower end 16 of the reinforcing material 12 is not supported by the support legs 3 and the reinforcing material 12 and the floor slab 2 are in a non-contact state with a gap b, the wall-side floor panel 4A is changed to the reinforcing material 12. The transmitted sound is not transmitted to the floor slab 2.
Further, since the wall-side end surface 6A and the wall surface 10 of the wall-side floor panel 4A are brought into a non-contact state with a gap a between them, a load is applied to the wall surface vicinity portion 11 of the wall side floor panel 4A and the wall surface vicinity portion 11 is moved up and down. Even if it moves, the wall-side end surface 6A and the wall surface 10 are prevented from rubbing, so that generation of rubbing noise can be prevented.

床下地構造１における、壁際床パネル４Ａの壁面近傍部分１１の剛性は、補強材１２の上下方向（壁際床パネル４Ａの下面７Ａより床スラブ２に向かう方向）に延長する長さｃの２乗に比例して大きくなるので、長さｃを長くすることで、壁際床パネル４Ａの壁面近傍部分１１の剛性を向上できる。
よって、補強材１２の上下方向に延長する長さｃを調整することによって、壁際床パネル４Ａの壁面近傍部分１１に所望の剛性を与えることができるようになり、また、壁際床パネル４Ａを支持する支持脚であって壁面１０に近い位置に設置する支持脚３Ａの配置位置を調整することによって、壁際床パネル４Ａの壁面近傍部分１１の荷重に対する沈み込み量を調整することが可能となる。
例えば、床スラブ２と壁側床パネル４Ａの下面７Ａとの間隔ｂが１５０ｍｍ〜２００ｍｍ程度の場合には、壁面１０に近い位置に設置する支持脚３Ａを、壁面１０から２００ｍｍ程度離れた位置に設置し、かつ、補強材１２の上下方向に延長する長さｃを５０ｍｍから１００ｍｍ程度にする。隙間ａは５ｍｍ〜１０ｍｍ程度である。 In the floor foundation structure 1, the rigidity of the near-wall portion 11 of the wall-side floor panel 4 </ b> A is the square of the length c extending in the vertical direction of the reinforcing material 12 (the direction from the lower surface 7 </ b> A of the wall-side floor panel 4 </ b> A toward the floor slab 2). Therefore, by increasing the length c, the rigidity of the portion 11 near the wall surface of the wall-side floor panel 4A can be improved.
Therefore, by adjusting the length c of the reinforcing member 12 extending in the vertical direction, a desired rigidity can be given to the wall surface vicinity portion 11 of the wall-side floor panel 4A, and the wall-side floor panel 4A is supported. By adjusting the arrangement position of the support legs 3A that are installed at positions close to the wall surface 10, it is possible to adjust the sinking amount with respect to the load of the wall surface vicinity portion 11 of the wall-side floor panel 4A.
For example, when the distance b between the floor slab 2 and the lower surface 7A of the wall-side floor panel 4A is about 150 mm to 200 mm, the support leg 3A installed near the wall surface 10 is placed at a position about 200 mm away from the wall surface 10. The length c that is installed and extends in the vertical direction of the reinforcing member 12 is set to about 50 mm to 100 mm. The gap a is about 5 mm to 10 mm.

補強材１２としては、パーティクルボード、木材、石膏ボード、金属、中密度繊維板（MDF (medium density fiberboard)、木質系建材、断熱性建材、樹脂、紙などにより形成されたものを用いればよい。   The reinforcing material 12 may be made of particle board, wood, gypsum board, metal, medium density fiberboard (MDF), wood-based building material, heat insulating building material, resin, paper, or the like.

支持脚３は、床スラブ２に設置される防振ゴム３１と、下部が防振ゴムに取付けられて防振ゴムに支持される例えば金属製の支柱３２と、支柱の上端部に設けられた台座３３とを備える。支柱３２の上部の外周面は図外の雄ねじ部に形成される。台座３３は、例えばパーティクルボードや合板などで形成される。台座３３は、台座３３の上下面に貫通する図外の貫通孔を備え、この貫通孔内には上下に貫通する図外の金属製の筒３４が設けられ、この筒３４の内周面は図外の雌ねじ部に形成される。つまり、支持脚３は、雄ねじ部の雄ねじと雌ねじ部の雌ねじとのねじ嵌合により台座３３が支柱３２に対して上下に移動可能に構成され、台座３３の高さを調整可能である。室内５の壁際に配置される支持脚３Ａの防振ゴム３１Ａ（３１）の硬度は、室内５の中央側に配置される支持脚３の防振ゴム３１の硬度よりも硬い。   The support legs 3 are provided at the vibration isolating rubber 31 installed on the floor slab 2, the lower part attached to the anti-vibration rubber and supported by the anti-vibration rubber, for example, a metal support 32, and the upper end of the support. A pedestal 33 is provided. The outer peripheral surface of the upper portion of the support column 32 is formed in a male screw portion (not shown). The pedestal 33 is formed of, for example, a particle board or plywood. The pedestal 33 is provided with an unillustrated through-hole penetrating the upper and lower surfaces of the pedestal 33, and a non-illustrated metal cylinder 34 penetrating vertically is provided in the through-hole. It is formed in a female thread portion outside the figure. That is, the support leg 3 is configured such that the pedestal 33 can move up and down with respect to the support column 32 by screw fitting of the male screw of the male screw portion and the female screw of the female screw portion, and the height of the pedestal 33 can be adjusted. The hardness of the anti-vibration rubber 31 </ b> A (31) of the support leg 3 </ b> A disposed near the wall of the room 5 is harder than the hardness of the anti-vibration rubber 31 of the support leg 3 disposed on the center side of the room 5.

以上のように構成された床下地構造１における床パネル４の上面に、図１に示すように、下地材２１が設けられ、その下地材２１の上に仕上げ材２２が設けられることによって、床スラブ２と、支持脚３と、床パネル４と、下地材２１と、仕上げ材２２とを備えた二重床２０が構成される。下地材２１と壁面１０との間、及び、仕上げ材２２と壁面１０との間にも隙間ｇを設ける。これら隙間ｇは２ｍｍ〜５ｍｍ程度である。   As shown in FIG. 1, a base material 21 is provided on the upper surface of the floor panel 4 in the floor base structure 1 configured as described above, and a finishing material 22 is provided on the base material 21. A double floor 20 including a slab 2, support legs 3, a floor panel 4, a base material 21, and a finishing material 22 is configured. A gap g is also provided between the base material 21 and the wall surface 10 and between the finishing material 22 and the wall surface 10. These gaps g are about 2 mm to 5 mm.

床パネル４、下地材２１、仕上げ材２２の材質や形状などは特に限定されないが、床パネル４は、例えばパーティクルボードにより形成され、下地材２１は、例えば合板により形成され、仕上げ材２２は、例えば、フローリングやカーペットにより形成される。   The material and shape of the floor panel 4, the base material 21, and the finishing material 22 are not particularly limited, but the floor panel 4 is formed by, for example, particle board, the base material 21 is formed by, for example, plywood, and the finishing material 22 is For example, it is formed of flooring or carpet.

最良の形態１の床下地構造１によれば、壁側床パネル４Ａの壁面近傍部分１１の下面７Ａに強固に一体化されるように取付けられた補強材１２と床スラブ２とが間隔ｂを隔てて非接触状態となり、かつ、壁際床パネル４Ａの壁側端面６Ａと壁面１０とが隙間ａを隔てて非接触状態となるように、壁側床パネル４Ａの下面７Ａが支持脚３により支持され、補強材１２の下端１６が支持脚３により支持されていない構成としたので、壁際床パネル４Ａから階下への音の伝播を少なくできる。また、壁側床パネル４Ａの壁面近傍部分１１をシステム根太や支持脚３で支持しない構成とできて経済的であるとともに、壁側床パネル４Ａの壁面近傍部分１１をシステム根太や支持脚３で支持しない構成でも、補強材１２を備えたことによって壁際床パネル４Ａの壁面近傍部分１１の剛性を確保できるようになる。   According to the floor foundation structure 1 of the best mode 1, the reinforcing material 12 and the floor slab 2 attached so as to be firmly integrated with the lower surface 7A of the wall surface vicinity portion 11 of the wall side floor panel 4A have a space b. The lower surface 7A of the wall-side floor panel 4A is supported by the support legs 3 so that the wall-side end panel 6A and the wall surface 10 of the wall-side floor panel 4A are in a non-contact state with a gap a therebetween. In addition, since the lower end 16 of the reinforcing member 12 is not supported by the support legs 3, the propagation of sound from the wall floor panel 4A to the downstairs can be reduced. Further, it is economical that the wall surface vicinity portion 11 of the wall side floor panel 4A is not supported by the system joists and the support legs 3, and the wall surface vicinity portion 11 of the wall side floor panel 4A is formed by the system joists and the support legs 3. Even in a configuration that does not support, the rigidity of the wall surface vicinity portion 11 of the wall-side floor panel 4A can be secured by providing the reinforcing member 12.

最良の形態２
図３；４に示すように、補強材１２が壁側床パネル４Ａの下面７Ａに沿って壁面１０より離れる方向Ｘに延長するように設けられた構成の床下地構造１としてもよい。
最良の形態２によれば、壁際床パネル４Ａの壁面近傍部分１１をより広い範囲で補強可能となる。 Best form 2
As shown in FIGS. 3 and 4, the floor foundation structure 1 may be configured such that the reinforcing member 12 extends in the direction X away from the wall surface 10 along the lower surface 7A of the wall-side floor panel 4A.
According to the best mode 2, it is possible to reinforce the wall surface vicinity portion 11 of the wall-side floor panel 4A in a wider range.

最良の形態３
図３；４に示す最良の形態２の構成においては、補強材１２の上下方向に延長する長さｃが短い場合には、壁際床パネル４Ａの壁面近傍部分１１に対する補強効果が小さいので、最良の形態２の構成において、補強材１２の上下方向に延長する長さｃを長くする。即ち、補強材１２が、壁際床パネル４Ａの下面７Ａより床スラブ２に向かって延長するとともに、壁際床パネル４Ａの下面７Ａに沿って壁面１０より離れる方向Ｘに延長するように設けられた構成としてもよい。
最良の形態３によれば、壁際床パネル４Ａの壁面近傍部分１１をより広い範囲でより効果的に補強可能となる。 Best form 3
