JP 2007-04-0093 A

本発明は、上記事実を考慮して、床衝撃音の遮断性能が良好で、高さの低い床下にも施工でき、さらに、同一質量の質量体を用いて水平方向の干渉範囲を狭くすることの可能な床支持具及び床構造を提供することを課題とする。   In consideration of the above facts, the present invention has good floor impact sound blocking performance and can be installed under a low floor, and further, the mass range of the same mass is used to narrow the horizontal interference range. It is an object of the present invention to provide a floor support and a floor structure that can be used.

請求項1に記載する本発明の床支持具は、床スラブ上に配置され、弾性変形可能であって振動を減衰させる第1弾性部材と、前記第1弾性部材上に支持され、前記第1弾性部材と反対側へ延びて床材を支持する支持部材と、前記第1弾性部材又は前記支持部材に支持され、弾性変形可能であって振動を減衰させる第2弾性部材と、水平方向の断面が円形とされ、下面に前記第2弾性部材を収納する凹部が構成されると共に前記第2弾性部材に支持され、前記第2弾性部材の弾性変形によって変位して振動を減衰させる質量体と、を備えている。   The floor support of the present invention according to claim 1 is disposed on a floor slab, is elastically deformable and damps vibrations, and is supported on the first elastic member. A support member that extends to the opposite side of the elastic member and supports the flooring; a second elastic member that is supported by the first elastic member or the support member and is elastically deformable and damps vibration; and a horizontal section A mass body configured to have a circular shape, a concave portion for accommodating the second elastic member on the lower surface and supported by the second elastic member, and displaced by elastic deformation of the second elastic member to attenuate vibrations; It has.

請求項1に記載する床支持具によれば、床材に振動が加わった場合、この振動は、第2弾性部材へ伝わる。これによって、第2弾性部材が弾性変形して質量体が振動を吸収するように上下動することで、床材から床スラブへの振動を減衰する。減衰された振動は、さらに第1弾性部材によって減衰されて床スラブへ伝わるので、床衝撃音が良好に遮断される。   According to the floor support tool of the first aspect, when vibration is applied to the floor material, the vibration is transmitted to the second elastic member. Thus, the vibration from the floor material to the floor slab is attenuated by the second elastic member moving up and down so that the mass body absorbs vibration by elastic deformation. The damped vibration is further damped by the first elastic member and transmitted to the floor slab, so that the floor impact sound is well cut off.

また、質量体の下面に凹部が構成され、この凹部に第2弾性体が収納されているので、第2弾性体の厚みが凹部によって吸収され、床支持具の高さを低くすることができる。   Moreover, since a recessed part is comprised in the lower surface of a mass body, and the 2nd elastic body is accommodated in this recessed part, the thickness of a 2nd elastic body is absorbed by a recessed part and the height of a floor support can be made low. .

また、質量体の水平方向の断面が円形とされているので、同一質量で他の形状の質量体を用いた場合と比較して、水平方向の干渉範囲を狭くすることができる。   Moreover, since the cross section of the mass body in the horizontal direction is circular, the horizontal interference range can be narrowed compared to the case of using mass bodies of the same mass and other shapes.

請求項2に記載する本発明の床支持具は、前記凹部が、前記質量体の中心軸と同軸の円柱状に構成されていること、を特徴とする。   The floor support of the present invention described in claim 2 is characterized in that the recess is formed in a columnar shape coaxial with the central axis of the mass body.

このように、凹部を構成することにより、バランスのよい質量体とすることができる。   Thus, it can be set as a mass body with sufficient balance by comprising a recessed part.

請求項3に記載する本発明の床支持具は、前記支持部材が、前記質量体の中心軸に沿って配置されていること、を特徴とする。   The floor support of the present invention described in claim 3 is characterized in that the support member is disposed along a central axis of the mass body.

このように、支持部材を質量体の中心軸に沿って配置することにより、振動に対してバランスのよい構成とすることができる。   Thus, by arranging the support member along the central axis of the mass body, it is possible to obtain a configuration with a good balance against vibration.

請求項4に記載する床構造は、床スラブと、前記床スラブ上に配置された請求項1〜3のいずれか1項に記載の床支持具と、を備えている。   The floor structure described in claim 4 includes a floor slab and the floor support according to any one of claims 1 to 3 disposed on the floor slab.

請求項4の床構造によれば、質量体の下面に凹部が構成され、この凹部に第2弾性体が収納されているので、第2弾性体の厚みが凹部によって吸収され、床支持具の高さを低くすることができる。また、質量体の水平方向の断面が円形とされているので、同一質量のものを用いた場合に、水平方向の干渉範囲を狭くすることができる。   According to the floor structure of the fourth aspect, since the concave portion is formed on the lower surface of the mass body, and the second elastic body is accommodated in the concave portion, the thickness of the second elastic body is absorbed by the concave portion. The height can be lowered. Moreover, since the cross section of the mass body in the horizontal direction is circular, when the same mass is used, the horizontal interference range can be narrowed.

以上説明したように、本発明の床支持具及び床構造によれば、床衝撃音の遮断性能が良好で、高さの低い床下にも施工でき、さらに、同一質量の質量体を用いて水平方向の干渉範囲を狭くすることができる。   As described above, according to the floor support and the floor structure of the present invention, the floor impact sound can be shut off well and can be constructed even under a low floor, and further using a mass body of the same mass. The direction interference range can be narrowed.

本発明における床支持具、及び、この床支持具が適用される床構造の実施形態を図面に基づき説明する。なお、図中の矢印UPは床構造における上方向を示す。   An embodiment of a floor support in the present invention and a floor structure to which the floor support is applied will be described with reference to the drawings.

The height of the foundation panel 14A from the floor slab 12 can be adjusted by inserting the recess 22M of the support bolt 22 and rotating the support bolt 22.

中間受け部材20のフランジ部20Aの上面である受け面20Cには、クッション台座26が接着されている。すなわち、クッション台座26の下面が受け面20Cに固着されている。クッション台座26と中間受け部材20との接着は、加硫接着によって行うことができる。クッション台座26は、円筒状とされて中央に挿入孔26Aが形成されており、この挿入孔26Aに支持ボルト22が挿入された状態となっている。クッション台座26の設置状態での上部中央には、薄肉筒状で上方へ突出した突出部26Cとされている。突出部26Cの内径は、クッション台座26の下部における内径と同様となっている。クッション台座26は、上床材14からの振動を減衰させるために、中間受け部材20を介して支持ボルト22に支持されるものであり、軟質ゴムで構成されて弾性変形可能とされる。   A cushion pedestal 26 is bonded to the receiving surface 20C, which is the upper surface of the flange portion 20A of the intermediate receiving member 20. That is, the lower surface of the cushion pedestal 26 is fixed to the receiving surface 20C. Bonding of the cushion base 26 and the intermediate receiving member 20 can be performed by vulcanization bonding. The cushion pedestal 26 is cylindrical and has an insertion hole 26A formed in the center, and the support bolt 22 is inserted into the insertion hole 26A. At the upper center in the installed state of the cushion pedestal 26, there is a protruding portion 26C that protrudes upward in the form of a thin tube. The inner diameter of the protruding portion 26 </ b> C is the same as the inner diameter at the lower portion of the cushion base 26. The cushion pedestal 26 is supported by the support bolt 22 via the intermediate receiving member 20 in order to attenuate the vibration from the upper flooring 14, and is made of soft rubber and can be elastically deformed.

The mounting bracket 38 includes a cylindrical tube portion 38B and a flange portion 38A that is disposed below the tube portion 38B in the installed state and extends radially outward. The flange portion 38A is disposed on the upward surface 26D of the cushion pedestal 26, and the upward surface 26D of the cushion pedestal 26 and the outside of the protruding portion 26C are vulcanized and bonded to the mounting bracket 38. A male screw 38C is formed on the outer peripheral portion of the cylindrical portion 38B.

図4に示すように、質量体40は円柱形状で、設置状態での下面40Aの中央部に凹部42が構成されている。凹部42は、質量体40の中心軸と同軸の円柱状として構成されている。凹部42の径D1は、クッション台座26及びクッションゴム18の上側よりも大径とされており、深さD2は、クッション台座26の突出部26Cを除いた高さよりも長く構成されている。   As shown in FIG. 4, the mass body 40 has a cylindrical shape, and a recess 42 is formed at the center of the lower surface 40 </ b> A in the installed state. The recess 42 is configured as a cylindrical shape that is coaxial with the central axis of the mass body 40. The diameter D1 of the recess 42 is larger than the upper side of the cushion pedestal 26 and the cushion rubber 18, and the depth D2 is configured to be longer than the height excluding the protruding portion 26C of the cushion pedestal 26.

質量体40には、凹部42の中央部から質量体40の上面40A側にかけて、支持孔42Aが構成されている。支持孔42Aの内側には、雌ネジが構成されており、取付金具38の雄ネジ38Cと螺合される。これにより、質量体40がクッション台座26上に支持され、質量体40によって、クッション台座26には、圧縮方向の荷重が作用している。   In the mass body 40, a support hole 42A is formed from the central portion of the recess 42 to the upper surface 40A side of the mass body 40.

まず、一体化されたクッションゴム18、中間受け部材20、クッション台座26、及び、取付金具38を、クッションゴム18を下にして床スラブ12上に設置する。   First, the integrated cushion rubber 18, intermediate receiving member 20, cushion base 26, and mounting bracket 38 are installed on the floor slab 12 with the cushion rubber 18 facing down.

次に、パネル受け部材24の円筒部24Bを、支持パネル15の調整孔15Aへ圧入し、鍔部24A上に支持パネル15を配置して、パネル受け部材24に支持パネル15を固着する。   Next, the cylindrical portion 24 </ b> B of the panel receiving member 24 is press-fitted into the adjustment hole 15 </ b> A of the support panel 15, the support panel 15 is disposed on the flange portion 24 </ b> A, and the support panel 15 is fixed to the panel receiving member 24.

次に、質量体40の支持孔42Aの雌ネジに取付金具38の雄ネジ38Cを螺合させて、質量体40を取り付け、クッション台座26上に質量体40を支持する。   Next, the male screw 38 </ b> C of the mounting bracket 38 is screwed into the female screw of the support hole 42 </ b> A of the mass body 40 to attach the mass body 40, and the mass body 40 is supported on the cushion base 26.

次に、クッション台座26の挿入孔26Aに支持ボルト22を上方から挿入し、支持ボルト22の雄ネジ部22Aを中間受け部材20の雌ネジ部20Bに螺合させて取り付け、直立させる。そして、支持ボルト22の雄ネジ部22Bにパネル受け部材24の雌ネジ部24Cを螺合させる。   Next, the support bolt 22 is inserted into the insertion hole 26 </ b> A of the cushion base 26 from above, and the male screw portion 22 </ b> A of the support bolt 22 is screwed to the female screw portion 20 </ b> B of the intermediate receiving member 20 to be attached and erect. Then, the female screw portion 24C of the panel receiving member 24 is screwed into the male screw portion 22B of the support bolt 22.

次に、支持パネル15上に下地パネル14Aを敷設する。ここで、マイナスドライバを支持ボルト22の凹部22Mに差し込んで支持ボルト22を回転させることによって、床スラブ12からの下地パネル14Aの高さを調節する。   Next, the base panel 14 </ b> A is laid on the support panel 15. Here, the height of the base panel 14 </ b> A from the floor slab 12 is adjusted by inserting a flathead screwdriver into the recess 22 </ b> M of the support bolt 22 and rotating the support bolt 22.

次に、下地パネル14A上に捨張材14Bが敷設され、捨張材14B上に仕上げ材14Cが敷設される。このようにして、二重床の床構造10が構成される。   Next, the stripping material 14B is laid on the base panel 14A, and the finishing material 14C is laid on the stripping material 14B. In this way, a double floor structure 10 is constructed.

(作用)   (Function)

次に、上記の実施形態の作用を説明する。   Next, the operation of the above embodiment will be described.

上階で発せられた床衝撃音(例えば、歩行音等)の振動は、上床材14からパネル受け部材24、支持ボルト22、及び、中間受け部材20を介してクッション台座26へ伝わる。これによって、クッション台座26が弾性変形し、質量体40が振動を吸収するように上下動することで、振動を減衰する。   The vibration of floor impact sound (for example, walking sound) generated on the upper floor is transmitted from the upper floor material 14 to the cushion base 26 via the panel receiving member 24, the support bolt 22, and the intermediate receiving member 20. As a result, the cushion base 26 is elastically deformed, and the mass body 40 moves up and down so as to absorb the vibration, thereby attenuating the vibration.

ここで、クッション台座26及び質量体40は、支持ボルト22を囲んで配置されているため、支持ボルト22に沿って弾性変形し、支持ボルト22に沿って移動することになるので、動吸振の作用が安定する。   Here, since the cushion base 26 and the mass body 40 are disposed so as to surround the support bolt 22, the cushion base 26 and the mass body 40 are elastically deformed along the support bolt 22 and moved along the support bolt 22. The action is stable.

また、中間受け部材20にクッション台座26が固着され、クッション台座26に質量体40が固定されているので、例えば、振動によって質量体40がクッション台座26から浮く等のような無駄な移動を抑えられ、また、質量体40の移動を振動周期に追従させ易くなるので、動吸振効果を高めることができる。   Further, since the cushion base 26 is fixed to the intermediate receiving member 20 and the mass body 40 is fixed to the cushion base 26, for example, unnecessary movement such as the mass body 40 floating from the cushion base 26 due to vibration is suppressed. In addition, since the movement of the mass body 40 can easily follow the vibration cycle, the dynamic vibration absorption effect can be enhanced.

また、質量体40が円柱形状とされているので、同一質量で他の形状の質量体を用いた場合と比較して、水平方向の干渉範囲を狭くすることができる。   In addition, since the mass body 40 has a cylindrical shape, the interference range in the horizontal direction can be narrowed as compared with the case where a mass body having the same mass and another shape is used.

また、質量体40の下面に凹部42が構成され、凹部42にクッション台座26が収納されているので、クッション台座26の高さ分、床支持具16の高さを低くすることができると共に、クッション台座26を小動物から保護することができる。   Moreover, since the recessed part 42 is comprised in the lower surface of the mass body 40, and the cushion base 26 is accommodated in the recessed part 42, while being able to make the height of the floor support 16 low by the height of the cushion base 26, The cushion base 26 can be protected from small animals.

なお、本実施形態では、質量体40を円柱形状とした例について説明したが、質量体は水平方向の断面が円形であれば、他の形状、例えば、図5に示すように、台錐形状の質量体55とすることもできる。床スラブ12がコンクリート製であるコンクリート床の場合について説明したが、床スラブは、木製等の他の床スラブであってもよい。   In the present embodiment, an example in which the mass body 40 has a cylindrical shape has been described. However, the mass body has another shape, for example, a trapezoidal shape as shown in FIG. The mass body 55 can also be used. Although the case where the floor slab 12 is a concrete floor made of concrete has been described, the floor slab may be another floor slab such as wooden.
