Description
【考案の詳細な説明】 （産業上の利用分野） 本考案は、マンション等の中高層の建築物における床根
太の支持構造に関するものである （従来技術とその問題点） 従来、マンション等の中高層の建築物では、床上での歩
行や跳びはねによる衝撃力が床根太を介してコンクリー
トスラブ等の床下地に伝わって、階下に床衝撃音を伝え
やすいという問題があった。[Detailed Description of the Invention] (Industrial field of application) The present invention relates to a support structure for floor joists in middle- and high-rise buildings such as condominiums (prior art and its problems). In a building, there is a problem that the impact force due to walking or jumping on the floor is transmitted to the floor base such as the concrete slab through the floor joists, and the floor impact sound is easily transmitted to the downstairs.
従って、上記のような床衝撃音を緩和するために、従来
は、第５図に示すように、床下地（Ａ）と床根太（Ｂ）
の間にゴム等の板状弾性体（Ｃ）を介在させることが行
われていた。Therefore, in order to mitigate the floor impact sound as described above, conventionally, as shown in FIG. 5, a floor base (A) and a floor joist (B) are used.
A plate-like elastic body (C) such as rubber is interposed between the two.
上記構造によると、床上の衝撃力が、前記弾性体（Ｃ）
で吸収緩和されて、床下地（Ａ）への衝撃力の伝達が軽
減され、これによって階下（Ｄ）への衝撃音の放出が小
さくなる効果を有する。According to the above structure, the impact force on the floor is caused by the elastic body (C).
Is absorbed and relaxed, and the transmission of impact force to the floor base (A) is reduced, which has the effect of reducing the emission of impact sound to the downstairs (D).
しかしながら、床下地表面に大きな凹凸があると、床根
太と下地との間隔が一定しないので、上記板状弾性体
（Ｃ）の厚さを変えて高さ調整をせねばならず、床根太
のレベル調整に手間がかかっていた。However, if there is a large unevenness on the surface of the floor base, the distance between the floor joists and the base is not constant. Therefore, the thickness of the plate-like elastic body (C) must be changed to adjust the height. It took time to adjust the level.
一方、ボルト等のレベル調整金具と弾性体を組み合わせ
て、高さ調整自在に支持させたものがあるが、金具との
組み合わせによって支持体が高価になり、また、床根太
全体を金具付きの弾性支持体で支持させると、床根太に
レベル調整のボルトと嵌合する孔加工を多数箇所設ける
必要があり、床下地が金具と加工手間で高価になってし
まうという問題があった。On the other hand, there is a thing that supports the height adjustment freely by combining level adjustment metal fittings such as bolts and elastic bodies, but the combination of metal fittings makes the support expensive, and the entire floor joist is elastic with metal fittings. When it is supported by a support, it is necessary to provide a lot of holes in the floor joists to be fitted with level adjusting bolts, and there is a problem that the floor base becomes expensive due to the metal fittings and the processing labor.
他方、間隔の異なる隙間を簡単に充填するものとして、
楔が知られているが、弾性材で楔を形成すると、床の振
動による圧縮復元の繰り返しで、楔の嵌合に「ずれ」が
生じて床根太と床下地の間から抜け出てしまうという問
題があった。On the other hand, to easily fill gaps with different intervals,
A wedge is known, but if the wedge is made of an elastic material, the compression will be repeatedly restored by the vibration of the floor, causing a "misalignment" in the fitting of the wedge, causing the wedge to slip out between the floor joist and the floor base. was there.
また、弾性体を楔形状にすると、床下地表面に小さな凹
凸が有れば、弾性体の下面と床下地の表面の密着性が悪
くなり、衝撃力の反動が楔の下面に不均一に作用して楔
の「ずれ」や「抜け」を助長して、安定支持が出来なく
なるという問題があった。In addition, if the elastic body is wedge-shaped, if there are small irregularities on the surface of the floor base, the adhesion between the lower surface of the elastic body and the surface of the floor base deteriorates, and the reaction of the impact force acts unevenly on the lower surface of the wedge. Then, there was a problem that it was not possible to support stably because it contributed to the "displacement" and "removal" of the wedge.
（考案の目的） 本考案は、上記従来の問題点に鑑みてなされたものであ

床根太の支持構造を提供するものである。(Purpose of the Invention) The present invention has been made in view of the above-mentioned conventional problems, and the wedge-shaped elastic body absorbs the transmission of the impact force from the floor joists to easily cope with the unevenness of the floor base. In addition, the present invention provides an inexpensive floor joist support structure that is excellent in soundproofness and workability in that the wedge-shaped elastic body does not "shift" or "drop" even when the impact force is repeated.
（考案の構成） 上記目的を達成するために、本考案は、傾斜面に滑り止

ある。(Structure of the Invention) In order to achieve the above object, the present invention provides a wedge-shaped elastic body having a substantially triangular cross section and made of a rubber material having a rubber hardness of 30 to 60 degrees, which is provided with a non-slip convex portion on an inclined surface. The non-slip convex portions of the surface are engaged with each other to form a pair of upper and lower layers, which are inserted between the floor joist lower surface and the floor base surface.
Of the upper and lower wedge-shaped elastic bodies, a cushion material that is softer than the wedge-shaped elastic body is provided on the lower surface of the lower wedge-shaped elastic body.
（考案の作用） したがって、本考案によれば、傾斜面に滑り止め凸部を
設けたゴム硬度30〜60度のゴム質材料よりなる楔形弾性

の下に挿入してあるので、楔形弾性体の当接面同士が上
記滑り止め凸部の係合で「ずれ防止」されているので、
上下の楔形弾性体が振動でずれ合うことがない。Therefore, according to the present invention, a wedge-shaped elastic body made of a rubber material having a rubber hardness of 30 to 60 degrees and provided with anti-slip protrusions on the inclined surfaces engages the anti-slip protrusions between the inclined surfaces. Since they are inserted together and inserted under the floor joist, the contact surfaces of the wedge-shaped elastic bodies are "prevented from being displaced" by the engagement of the above-mentioned non-slip projections.
The upper and lower wedge-shaped elastic bodies do not shift due to vibration.
また、下方の楔形弾性体の下面に該楔形弾性体よりも軟
質のクッション材を設けているので、このクッション材
が床下地の小さい凹凸を吸収して楔形弾性体の下面を安
定した状態で床下地上に設置させ、楔形弾性体の衝撃吸
収性が均一に発揮される。Further, since a cushion material that is softer than the wedge-shaped elastic body is provided on the lower surface of the lower wedge-shaped elastic body, this cushion material absorbs the small irregularities of the floor base and stabilizes the lower surface of the wedge-shaped elastic body under the floor. Installed on the ground, the impact absorption of the wedge-shaped elastic body is exhibited uniformly.
（実施例） 以下、本考案を、その一実施例を示す図面にしたがって
説明する。(Embodiment) Hereinafter, the present invention will be described with reference to the drawings showing an embodiment thereof.
第１図は、本考案の床根太の支持構造の一実施例を示
し、コンクリート床スラブからなる床下地（１）の上
に、後述する楔形弾性体（2a）（2b）が上下一対の重ね
合わせ状態で配されており、その上に床根太材（３）が
載置されている。FIG. 1 shows an embodiment of a floor joist support structure of the present invention, in which a wedge-shaped elastic body (2a) (2b) described later is superposed on a floor base (1) made of a concrete floor slab in a pair. The floor joists (3) are placed on top of each other.
楔形弾性体（2a）（2b）は、第２図に示すように、ゴム
硬度30〜60度のゴム質材料によりなる傾斜角度が約５度
の断面略直角三角形に形成されており、その傾斜面（20
a）（20b）には、傾斜方向（矢印A1）と直交する方向に
沿った、滑り止め凸部（21a）（21b）が4mm間隔で平行
に複数突設されている。As shown in FIG. 2, the wedge-shaped elastic bodies (2a) and (2b) are made of a rubber material having a rubber hardness of 30 to 60 degrees and are formed in a substantially right-angled triangle having a tilt angle of about 5 degrees. Face (20
In a) and (20b), a plurality of anti-slip projections (21a) and (21b) are provided in parallel at intervals of 4 mm along the direction orthogonal to the inclination direction (arrow A 1 ).
楔形弾性体の最高高さ寸法は17mm、先端部の最低高さ寸
法は5mmに形成されている。The wedge-shaped elastic body has a maximum height of 17 mm and a tip has a minimum height of 5 mm.
従って、上記楔形弾性体（2a）（2b）を、その傾斜面
（20a）（20b）同士を当接させて重ね合わせると、滑り
止め凸部（21a）（21b）が、相互に係合し合って傾斜面
のずれを防止するとともに、傾斜面（20a）（20b）の重
ね合わせ幅を変化させることで楔形弾性体の積層状態の
高さ寸法を17〜30mmの強の範囲を0.5〜0.7mm刻みで変化
させることができる。Therefore, when the wedge-shaped elastic bodies (2a) and (2b) are overlapped with their inclined surfaces (20a) and (20b) abutting against each other, the anti-slip projections (21a) and (21b) are engaged with each other. The height of the wedge-shaped elastic body in the stacked state is adjusted to 17 to 30 mm by adjusting the overlapping width of the inclined surfaces (20a) and (20b) to 0.5 to 0.7 in addition to preventing the displacement of the inclined surfaces. It can be changed in mm increments.
また、上記滑り止め凸部は、楔形弾性体に一体に突設さ
れたゴム質のものであるので、当接面に摩擦音を生じる
ことがない。Further, since the above-mentioned non-slip convex portion is made of rubber integrally provided on the wedge-shaped elastic body, no frictional noise is generated on the contact surface.
なお、上記滑り止め凸部（21a）（21b）は、図示した直
線状の凸部に限らず、互いに係合し合う形状であればよ
い。The anti-slip projections (21a) and (21b) are not limited to the linear projections shown in the figure, and may have shapes that engage with each other.
上記楔形弾性体（2a）（2b）は、ゴム硬度30〜60度のゴ
ム質材料より形成されている。The wedge-shaped elastic bodies (2a) (2b) are made of a rubber material having a rubber hardness of 30 to 60 degrees.
ここで、ゴム硬度を30度より大きくした理由は、ゴム硬
度が30度未満であれば、床面の床仕上材や家具等の荷重
で滑り止め凸部（21a）（21b）が偏平形状に圧縮変形し
て傾斜面の滑り止め効果を発揮できなくなり、楔形弾性
体（2a）（2b）の重ね合わせ面にずれを生じるためであ
る。Here, the reason why the rubber hardness is greater than 30 degrees is that if the rubber hardness is less than 30 degrees, the anti-slip protrusions (21a) (21b) will be flattened by the load of the floor finishing material or furniture on the floor surface. This is because the inclined surfaces cannot be prevented from slipping due to compressive deformation, and the overlapping surfaces of the wedge-shaped elastic bodies (2a) and (2b) are displaced.
また、ゴム硬度を60度より小さくした理由は、ゴム硬度
が60度より大きいと床衝撃力の吸収が不十分で、衝撃音
を伝達し易くなるためである。The reason why the rubber hardness is smaller than 60 degrees is that if the rubber hardness is larger than 60 degrees, the floor impact force is not sufficiently absorbed and the impact sound is easily transmitted.
上記楔形弾性体（2a）（2b）のゴム硬度は、同一硬度ま
たは異なった硬度の組み合わせのいずれでもよい。The rubber hardness of the wedge-shaped elastic bodies (2a) and (2b) may be the same hardness or a combination of different hardnesses.
この実施例では、床下地側の楔形弾性体（2a）の硬度を
ゴム硬度35度の柔らかいものにして床下地（１）との密
着を高めると共に、根太材側の楔形弾性体（2b）のゴム
硬度を50度の比較的固いものにして根太材（３）下面の
安定支持を行っている。In this embodiment, the wedge-shaped elastic body (2a) on the floor base side is made to have a softness of rubber hardness of 35 degrees to enhance the adhesion with the floor base (1) and the wedge-shaped elastic body (2b) on the joist side. The rubber hardness is set to be relatively hard at 50 degrees to stably support the bottom surface of the joist (3).
また、第１図に示すように床根太（３）の両端部は、跳

る。Further, as shown in FIG. 1, both ends of the floor joist (3) are fixed to the floor undercoat (1) by a composite support body (4) (4) of a bolt and an elastic body in order to prevent jumping up, and the floor joist (3) is fixed. (3) Prevents both ends from jumping up, and the wedge-shaped elastic bodies (2a) and (2b) are superposed on the lower surface of the central portion of the floor joist with the composite support bodies (4) and (4) at appropriate intervals. It is adjusted, inserted, and supported at multiple points.
上記複合支持体（４）（４）は、床根太の少なくとも両
端部に設けておくと、床根太の跳ね上がりが防止され
て、楔形弾性体の「ずれ」や「抜け」が完全に防止され
るので好ましい。If the composite support bodies (4) and (4) are provided at least at both ends of the floor joist, the floor joist is prevented from jumping up, and the “shift” and “dropout” of the wedge-shaped elastic body are completely prevented. Therefore, it is preferable.
なお、複合支持体（４）（４）は、金具の複合で高価な
ものであるので、床根太の跳ね上がりを防止し得る必要
最小限の個数と間隔で用いればよい。Since the composite supports (4) and (4) are expensive because of the combination of the metal fittings, the composite supports (4) and (4) may be used with the minimum necessary number and intervals that can prevent the floor joist from jumping up.
