When the Asker A hardness is in the range of 30 or more and 80 or less, the effect of suppressing vibration transmission from the floor material 31 to the base 21 can be enhanced. When the Asker A hardness is 40 or more, the floor material 31 can be prevented from sinking when a load is applied from above the floor material 31. On the other hand, when the Asker A hardness is 70 or less, the effect of suppressing vibration transmission from the floor material 31 to the base 21 can be further enhanced.

ゴム系材料としては、例えば、天然ゴム、ポリイソプレンゴム、スチレン・ブタジエンゴム、ポリブタジエンゴム、ニトリルゴム、ブチルゴム、エチレンプロピレンゴム、ウレタンゴム、及びシリコーンゴムが挙げられる。ゴム系材料は、一種を用いてもよいし、二種以上を用いてもよい。ゴム系材料には、フィラー等の補強材や老化防止剤等の添加剤を含有させることもできる。   Examples of the rubber-based material include natural rubber, polyisoprene rubber, styrene / butadiene rubber, polybutadiene rubber, nitrile rubber, butyl rubber, ethylene propylene rubber, urethane rubber, and silicone rubber. One type of rubber material may be used, or two or more types may be used. The rubber-based material can contain a reinforcing material such as a filler and an additive such as an anti-aging agent.

床構造１１は、厚さ調整部材７１をさらに備えている。厚さ調整部材７１は、凹部用緩衝部材６３を構成するゴム系材料よりも硬質な硬質材料から構成されている。厚さ調整部材７１は、基台２１と床材３１の凹部３１ａとの間において凹部用緩衝部材６３に積層されている。厚さ調整部材７１は、床材３１における凹部３１ａの内奥面Ｓ１１に重なるように配置される上面Ｓ１２を有している。   The floor structure 11 further includes a thickness adjusting member 71. The thickness adjusting member 71 is made of a hard material that is harder than the rubber-based material that forms the recess cushioning member 63. The thickness adjusting member 71 is laminated on the recess cushioning member 63 between the base 21 and the recess 31 a of the floor material 31. The thickness adjusting member 71 has an upper surface S12 that is disposed so as to overlap the inner back surface S11 of the recess 31a in the flooring 31.

本実施形態のように、床材３１における凹部３１ａの内奥面Ｓ１１がリブＲを有する場合、厚さ調整部材７１の上面Ｓ１２は、リブＲの両側方に位置する内奥面Ｓ１１を支持するように離間した一対の上面Ｓ１２，Ｓ１２から構成することが好ましい。   When the inner back surface S11 of the recess 31a in the flooring 31 has the rib R as in the present embodiment, the upper surface S12 of the thickness adjusting member 71 supports the inner back surface S11 located on both sides of the rib R. It is preferable that the upper surface S12, S12 is separated from each other.

Examples of the material constituting the thickness adjusting member 71 include a resin material, wood, and wood material. Examples of the resin material include polyvinyl chloride, polyethylene, polypropylene, polyester, polystyrene, polyamide, and ABS resin. The resin material may contain a reinforcing material such as a filler and an additive such as an antioxidant.

凹部用緩衝部材６３の厚さＴ１は、凹部用緩衝部材６３と厚さ調整部材７１との合計の厚さＴ２を１００％とした場合、１５％以上であることが好ましく、より好ましくは３０％以上である。凹部用緩衝部材６３の厚さＴ１を厚くするほど、床材３１から基台２１への振動伝達を抑制する効果を高めることができる。凹部用緩衝部材６３の厚さＴ１は、上記合計の厚さＴ２を１００％とした場合、６０％以下であることが好ましく、より好ましくは５０％以下である。凹部用緩衝部材６３の厚さＴ１を薄くするほど、床材３１の上方から荷重が加わった際に床材３１が沈み込むことを抑えることができる。なお、凹部用緩衝部材６３の厚さＴ１、及び上記合計の厚さＴ２は、床材３１を載置する前の荷重を受けていない状態の厚さ寸法をいう。   The thickness T1 of the recess cushioning member 63 is preferably 15% or more, more preferably 30%, where the total thickness T2 of the recess cushioning member 63 and the thickness adjusting member 71 is 100%. That's it. As the thickness T1 of the recess cushioning member 63 is increased, the effect of suppressing vibration transmission from the floor 31 to the base 21 can be enhanced. The thickness T1 of the recess cushioning member 63 is preferably 60% or less, more preferably 50% or less, when the total thickness T2 is 100%. As the thickness T1 of the recess cushioning member 63 is decreased, the floor material 31 can be prevented from sinking when a load is applied from above the floor material 31. The thickness T1 of the recess cushioning member 63 and the total thickness T2 are thickness dimensions in a state in which the load before placing the flooring 31 is not received.

床構造１１の床面（床材３１の上面）には、図示を省略した床仕上げ材が配置される。床仕上げ材としては、例えば、フローリング、コルク板、タイル、畳、カーペット、樹脂シート材及びゴムシート材が挙げられる。床構造１１の下方には、図示を省略した下層階の天井部材が設けられる。床構造１１は、集合住宅や個人住宅等の多層住宅や各種多層施設に適用される。床構造１１は、多層施設の中でも、仮設住宅等の仮設建築物の床構造として好適である。   On the floor surface of the floor structure 11 (the upper surface of the floor material 31), a floor finishing material (not shown) is disposed. Examples of the floor finishing material include flooring, cork board, tile, tatami mat, carpet, resin sheet material, and rubber sheet material. Below the floor structure 11, a ceiling member of a lower floor (not shown) is provided. The floor structure 11 is applied to multi-layer houses and various multi-layer facilities such as apartment houses and individual houses. The floor structure 11 is suitable as a floor structure of a temporary building such as a temporary house among multi-layer facilities.

上述した実施形態によって発揮される作用効果について以下に記載する。
（１）床構造１１は、枠構造を有する基台２１と、基台２１上に配置された床材３１と、基台２１と床材３１とを連結する連結部材４１と、基台２１の枠構造を補強するブレース部材５１とを備えている。基台２１と床材３１とを連結する連結部材４１によりブレース部材５１が基台２１に連結されている。この構成によれば、床構造１１から連結部材４１を取り除くことで、基台２１とブレース部材５１との連結を解除することができる。これにより、基台２１から床材３１とブレース部材５１とを取り外す作業を簡略化することができるため、床構造１１を容易に解体することができる。 The operational effects exhibited by the above-described embodiment will be described below.
(1) The floor structure 11 includes a base 21 having a frame structure, a flooring 31 disposed on the base 21, a connecting member 41 that connects the base 21 and the flooring 31, and the base 21 And a brace member 51 for reinforcing the frame structure. A brace member 51 is connected to the base 21 by a connecting member 41 that connects the base 21 and the flooring 31. According to this configuration, the connection between the base 21 and the brace member 51 can be released by removing the connection member 41 from the floor structure 11. Thereby, since the operation | work which removes the flooring 31 and the brace member 51 from the base 21 can be simplified, the floor structure 11 can be disassembled easily.

（２）例えば、ブレース部材を基台２１の上フランジ２３の下面側に取り付けた場合、連結部材を取り除く際に、ブレース部材の脱落を防止する目的でブレース部材を下方から支持する必要がある。これに対して、本実施形態のブレース部材５１は、基台２１と床材３１との間に配置されている。この場合、連結部材４１を取り除く際に、ブレース部材５１は基台２１に支持される。これにより、ブレース部材５１を取り外す作業がさらに容易となるため、床構造１１をさらに容易に解体することができる。   (2) For example, when the brace member is attached to the lower surface side of the upper flange 23 of the base 21, it is necessary to support the brace member from below for the purpose of preventing the brace member from falling off when the connecting member is removed. On the other hand, the brace member 51 of the present embodiment is disposed between the base 21 and the floor material 31. In this case, the brace member 51 is supported by the base 21 when the connecting member 41 is removed. Thereby, since the operation | work which removes the brace member 51 becomes still easier, the floor structure 11 can be disassembled still more easily.

（３）本実施形態の床構造１１では、基台２１と床材３１との間に緩衝部材６１が配置されている。この場合、連結部材４１を取り除く際や連結部材４１を取り除いた後に、基台２１に対する床材３１の位置ずれが緩衝部材６１により抑制されるため、基台２１から床材３１を取り外す作業が容易となる。従って、床構造１１をさらに容易に解体することができる。また、床構造１１の解体の際には、緩衝部材６１により基台２１と床材３１との接触が抑制されるため、床材３１が損傷し難い。このため、例えば、床材３１の再利用に好適である。   (3) In the floor structure 11 of the present embodiment, the buffer member 61 is disposed between the base 21 and the floor material 31. In this case, when the connecting member 41 is removed or after the connecting member 41 is removed, the buffer member 61 suppresses the displacement of the floor material 31 with respect to the base 21, so that the work of removing the floor material 31 from the base 21 is easy. It becomes. Therefore, the floor structure 11 can be disassembled more easily. Further, when the floor structure 11 is disassembled, the contact between the base 21 and the floor material 31 is suppressed by the buffer member 61, so that the floor material 31 is hardly damaged. For this reason, it is suitable for the reuse of the flooring 31, for example.

また、床構造１１を備えた多層施設の使用時においては、床材３１から基台２１への振動伝達が、緩衝部材６１によって抑制される。従って、床構造１１の下方における騒音を抑制することができる。基台２１と床材３１との間は、例えば、床材３１から基台２１に重量床衝撃音を伝達する伝達経路となり易いため、上記構成は、そうした重量床衝撃音を抑える点で有利となる。   In addition, when the multi-layer facility provided with the floor structure 11 is used, vibration transmission from the floor material 31 to the base 21 is suppressed by the buffer member 61. Therefore, noise below the floor structure 11 can be suppressed. Between the base 21 and the floor 31, for example, a transmission path for transmitting a heavy floor impact sound from the floor 31 to the base 21 is likely to be provided. Therefore, the above configuration is advantageous in terms of suppressing the heavy floor impact sound. Become.

（４）床構造１１は、基台２１と床材３１の凸部３１ｂとの間に配置された凸部用緩衝部材６２を備えている。この場合、床材３１の凸部３１ｂから基台２１への振動伝達は、凸部用緩衝部材６２によって抑制される。従って、床構造１１の下方における騒音を抑制することができる。   (4) The floor structure 11 includes a convex buffer member 62 disposed between the base 21 and the convex portion 31 b of the floor material 31. In this case, vibration transmission from the convex portion 31 b of the floor material 31 to the base 21 is suppressed by the convex portion buffer member 62. Therefore, noise below the floor structure 11 can be suppressed.

（５）床構造１１は、基台２１と床材３１の凹部３１ａとの間に配置された凹部用緩衝部材６３を備えている。この場合、床材３１の凹部３１ａから基台２１への振動伝達は、凹部用緩衝部材６３によって抑制される。従って、床構造１１の下方における騒音を抑制することができる。   (5) The floor structure 11 includes a recess cushioning member 63 disposed between the base 21 and the recess 31 a of the floor material 31. In this case, vibration transmission from the recess 31 a of the floor material 31 to the base 21 is suppressed by the recess cushioning member 63. Therefore, noise below the floor structure 11 can be suppressed.

（６）床構造１１は、凹部用緩衝部材６３を構成するゴム系材料よりも硬質な硬質材料から構成される厚さ調整部材７１をさらに備えている。厚さ調整部材７１は、基台２１と床材３１の凹部３１ａとの間において凹部用緩衝部材６３に積層されている。   (6) The floor structure 11 further includes a thickness adjusting member 71 made of a hard material that is harder than the rubber-based material constituting the recessed portion buffering member 63. The thickness adjusting member 71 is laminated on the recess cushioning member 63 between the base 21 and the recess 31 a of the floor material 31.

この床構造１１では、基台２１と床材３１の凹部３１ａとの間のスペースを利用して凹部用緩衝部材６３を配置する構成を有するため、凹部用緩衝部材６３の厚さをより厚く設定したとしても、基台２１に対して床材３１の高さ位置を一定に保つことが可能となる。ここで、凹部用緩衝部材６３の厚さを過剰に厚くすると、凹部用緩衝部材６３による床材３１の支持機能が低下するおそれがある。この点、上記床構造１１では、凹部用緩衝部材６３と、上記硬質材料から構成される厚さ調整部材７１とが積層されているため、凹部用緩衝部材６３の厚さと、厚さ調整部材７１の厚さを調整することで凹部用緩衝部材６３が過剰に厚くなることを抑えることができる。すなわち、凹部用緩衝部材６３の厚さをより厚く設定したとしても、基台２１に対して床材３１の高さ位置を一定に保つことが可能となり、また、凹部用緩衝部材６３が過剰に厚くなることを抑えることができる。従って、凹部用緩衝部材６３の性能を好適に発揮させることができる。   Since the floor structure 11 has a configuration in which the recess cushioning member 63 is disposed using the space between the base 21 and the recess 31a of the flooring 31, the thickness of the recess cushioning member 63 is set to be thicker. Even if it does, it becomes possible to keep the height position of the flooring 31 constant with respect to the base 21. Here, when the thickness of the recess cushioning member 63 is excessively increased, the function of supporting the floor 31 by the recess cushioning member 63 may be lowered. In this regard, in the floor structure 11, since the concave buffer member 63 and the thickness adjusting member 71 made of the hard material are laminated, the thickness of the concave buffer member 63 and the thickness adjusting member 71 are stacked. It can suppress that the buffer member 63 for recessed parts becomes thick too much by adjusting the thickness. That is, even if the thickness of the recess cushioning member 63 is set to be thicker, the height position of the floor 31 can be kept constant with respect to the base 21, and the recess cushioning member 63 is excessively large. Thickening can be suppressed. Therefore, the performance of the recess cushioning member 63 can be suitably exerted.

（７）床構造１１の凸部用緩衝部材６２は、連結部材４１（ボルト４２）に接しているため、凸部用緩衝部材６２によって連結部材４１の振動を抑制することもできる。なお、本実施形態の凸部用緩衝部材６２は貫通孔６２ａを有し、この貫通孔６２ａが連結部材４１（ボルト４２）に接しているが、例えば、貫通孔６２ａを省略した複数の凸部用緩衝部材６２により、連結部材４１を挟み込むようにして連結部材４１に接するように構成することもできる。   (7) Since the convex buffer member 62 of the floor structure 11 is in contact with the connecting member 41 (bolt 42), the convex buffer member 62 can also suppress the vibration of the connecting member 41. In addition, although the buffer member 62 for convex part of this embodiment has the through-hole 62a, and this through-hole 62a is in contact with the connection member 41 (bolt 42), for example, the some convex part which abbreviate | omitted the through-hole 62a The buffer member 62 may be configured to contact the connecting member 41 so as to sandwich the connecting member 41.
