Description

本発明は、建築物内装や空調設備機器等を防振支持するのに好適な吊り型防振ゴムに関する。   The present invention relates to a suspension type anti-vibration rubber suitable for anti-vibration support of a building interior, an air conditioning equipment, and the like.

従来この種の吊り型防振ゴムとして、図４や図５に示される吊り型防振ゴムが使われている。図４に示される吊り型防振ゴム４０は、矩形に折り曲げられた金属板からなるハンガーフレーム４１の上端面に、建築物の上部（図示せず）に係止される吊りボルト４６を連結し、ハンガーフレーム４１の下端面に、ゴム弾性体４２を介して防音室やホール等の天井や送風機のダクト等の被支持物（図示せず）を支持する支持ボルト４４を連結して構成されている（特許文献１参照）。図中符号４７、４８、４９は締付ナットを示している。   Conventionally, as this type of suspension type anti-vibration rubber, the suspension type anti-vibration rubber shown in FIGS. 4 and 5 has been used. The suspension type anti-vibration rubber 40 shown in FIG. 4 connects a suspension bolt 46 that is locked to an upper part (not shown) of a building to an upper end surface of a hanger frame 41 made of a metal plate bent into a rectangle. The hanger frame 41 is connected to a lower end surface of the hanger frame 41 via a rubber elastic body 42 and a support bolt 44 for supporting a supported object (not shown) such as a soundproof room, a ceiling of a hall, a duct of a blower or the like. (See Patent Document 1). In the figure, reference numerals 47, 48, and 49 denote tightening nuts.

また、図５に示される吊り型防振ゴム５０は、矩形のハンガーフレーム５１の両端面に、それぞれゴム弾性体５２、５４を介在させて吊りボルト５６と支持ボルト５７とをそれぞれ連結して構成されている。   Further, the suspension type anti-vibration rubber 50 shown in FIG. 5 is configured by connecting a suspension bolt 56 and a support bolt 57 to both end surfaces of a rectangular hanger frame 51 with rubber elastic bodies 52 and 54 interposed therebetween, respectively. Has been.

一般に防振ゴムは、固有振動数が小さいほど防振性能がよくなる。つまり、支持する荷重が同一であれば、ゴム弾性体のばね定数が低いほど防振性能がアップする。しかし、ばね定数が低くなると地震等による衝撃に対するゴム弾性体の変位が大きくなる。図４及び図５に示した吊り型防振ゴムにおいては、地震等の力に対する揺れ等の変位を制御できないため、建築物内装や空調設備機器等の被支持物の揺れも大きくなる。   In general, vibration-proof rubbers have better vibration-proof performance as the natural frequency is smaller. That is, if the load to support is the same, vibration-proof performance will improve, so that the spring constant of a rubber elastic body is low. However, when the spring constant is lowered, the displacement of the rubber elastic body with respect to an impact caused by an earthquake or the like is increased. In the suspension type anti-vibration rubber shown in FIGS. 4 and 5, since the displacement such as the shaking with respect to the force such as the earthquake cannot be controlled, the shaking of the supported object such as the interior of the building or the air conditioner equipment becomes large.

被支持物の揺れが過大になると、被支持物が建築物の側壁に接触あるいは衝突して破損や被支持物落下のおそれがある。逆に、ゴム弾性体のばね定数を高くして地震等の力に対する変位を押えるようにした場合には被支持物に対する所定の防振性能が得られない。
実公昭６２−４４００９号公報 If the supported object is excessively shaken, the supported object may come into contact with or collide with the side wall of the building, causing damage or falling of the supported object. On the contrary, when the spring constant of the rubber elastic body is increased to suppress the displacement against the force such as an earthquake, the predetermined vibration isolating performance for the supported object cannot be obtained.
Japanese Utility Model Publication No. 62-44009

既知の従来の技術には、次のような解決すべき課題があった。
図４及び図５に示した吊り型防振ゴムは、地震等の力に対する揺れ等の変位の制御はできない。そのため、防振性能を上げる目的で、ばね定数の低いゴム弾性体を用いると共に、別途構成された揺れ止め用防振ゴムを併用する必要があった。揺れ止め用防振ゴムは、被支持物と建築物の側壁との間に配設されるゴム弾性体を有するもので、被支持物の一定以上の水平方向、の揺れを押える役目がある。しかしながら、揺れ止め用防振ゴムを設置するためのスペースを確保する必要があり、また費用が嵩む等の課題がある。 The known prior art has the following problems to be solved.
The suspension type anti-vibration rubber shown in FIG. 4 and FIG. 5 cannot control displacement such as shaking with respect to a force such as an earthquake. For this reason, in order to improve the vibration proof performance, it is necessary to use a rubber elastic body having a low spring constant and to use a vibration proof rubber separately configured separately. The anti-vibration rubber for anti-swaying has a rubber elastic body disposed between the supported object and the side wall of the building, and has a function of suppressing the shaking of the supported object in a certain horizontal direction. However, there is a problem that it is necessary to secure a space for installing the anti-vibration rubber for shaking prevention, and the cost increases.

本発明は、上記の課題を解決するためになされたもので、揺れ止め用防振ゴムを使用することなく、被支持物の一定以上の揺れを抑制し得ると共に所定の防振効果を発揮する吊り型防振ゴムを提供することを目的とする。   The present invention has been made in order to solve the above-described problems, and can suppress a predetermined level or more of a supported object without using an anti-vibration rubber, and exhibits a predetermined anti-vibration effect. An object is to provide a suspension type anti-vibration rubber.

It is no longer necessary to secure a space for installing anti-vibration rubber for shaking prevention, leading to shortening of construction and cost reduction. A clearance is generated between the restraining plate and the end face of the hanger frame facing the restraining plate due to the protruding portion of the rubber elastic body.

以下、本発明の実施の形態を実施例毎に説明する。   Hereinafter, embodiments of the present invention will be described for each example.

図１は実施例１の吊り型防振ゴム１０を示す断面図である。
吊り型防振ゴム１０は、矩形のハンガーフレーム１２と、このハンガーフレーム１２の上端面に係止された吊りボルト１８と、ハンガーフレーム１２の下端面に係止された支持ボルト２０と、ハンガーフレーム１２と吊りボルト１８及び支持ボルト２０との間にそれぞれ配設された２つのゴム弾性体２２Ａ、２２Ｂと、ハンガーフレーム１２の上端面の外側に配設された抑制板２６とを備えている。 FIG. 1 is a cross-sectional view showing a suspended vibration-proof rubber 10 according to the first embodiment.
The suspension-type anti-vibration rubber 10 includes a rectangular hanger frame 12, a suspension bolt 18 locked to the upper end surface of the hanger frame 12, a support bolt 20 locked to the lower end surface of the hanger frame 12, and a hanger frame. 12, two rubber elastic bodies 22 </ b> A and 22 </ b> B disposed between the suspension bolt 18 and the support bolt 20, respectively, and a restraining plate 26 disposed outside the upper end surface of the hanger frame 12.

ハンガーフレーム１２は、２枚の板体１２Ａ、１２Ｂをそれぞれコ字状に折り曲げて矩形に合体して構成されている。ハンガーフレーム１２は、一枚の板体を矩形に折り曲げた形状とすることにより一体構成としてもよい。ハンガーフレーム１２の上端面と下端面の各中心部にそれぞれ貫通孔１４、１６が設けられている。   The hanger frame 12 is configured by bending two plate bodies 12A and 12B into U-shapes and combining them into a rectangle. The hanger frame 12 may have an integral configuration by bending a single plate into a rectangular shape. The through-holes 14 and 16 are provided in each center part of the upper end surface and lower end surface of the hanger frame 12, respectively.

ゴム弾性体２２Ａ、２２Ｂには軸心を貫通する中心孔２５Ａ、２５Ｂが設けられ、ゴム弾性体２２Ａ、２２Ｂの、各端面に筒状の突出部２４Ａ、２４Ｂが設けられている。これらの筒状の突出部２４Ａ、２４Ｂは、それぞれハンガーフレーム１２の各端面の貫通孔１４、１６内を経て外方に延設されている。筒状の突出部２４Ａ、２４Ｂは、圧縮されたとき外面が湾曲した凸面に膨らむ。ゴム弾性体２２Ａ、２２Ｂの、各端面にそれぞれ金属板２３Ａ、２３Ｂが接着されている。   The rubber elastic bodies 22A and 22B are provided with center holes 25A and 25B penetrating the shaft center, and cylindrical protrusions 24A and 24B are provided on the respective end faces of the rubber elastic bodies 22A and 22B. These cylindrical projecting portions 24A and 24B are extended outward through the through holes 14 and 16 on the respective end surfaces of the hanger frame 12. When the cylindrical protrusions 24A and 24B are compressed, the outer surfaces bulge into convex surfaces with curved surfaces. Metal plates 23A and 23B are bonded to the end surfaces of the rubber elastic bodies 22A and 22B, respectively.

吊りボルト１８は、ハンガーフレーム１２の上端面の貫通孔１４とゴム弾性体２２Ａの中心孔２５Ａに挿入され、ゴム弾性体２２Ａの両側に配置されたナット２８及びナット３２を締め付けることにより係止されている。支持ボルト２０は、ハンガーフレーム１２の下端面の貫通孔１６とゴム弾性体２２Ｂの中心孔２５Ｂとに挿入され、ゴム弾性体２２Ｂの両側に配置されたナット３０及びナット３４を締め付けることにより係止されている。   The suspension bolt 18 is inserted into the through hole 14 on the upper end surface of the hanger frame 12 and the center hole 25A of the rubber elastic body 22A, and is locked by tightening nuts 28 and nuts 32 arranged on both sides of the rubber elastic body 22A. ing. The support bolt 20 is inserted into the through hole 16 on the lower end surface of the hanger frame 12 and the center hole 25B of the rubber elastic body 22B, and is locked by tightening the nut 30 and the nut 34 disposed on both sides of the rubber elastic body 22B. Has been.

抑制板２６は、対向する筒状の突出部２４Ａの外径より大きい平板である。抑制板２６は、筒状の突出部２４Ａの端面とそれに対向するナット２８との間に配設されている。抑制板２６は、任意の方向に揺動させるため円形平板としたり、揺動に方向性をもたせるため四角平板にするなどを適宜選択すればよい。抑制板２６は、抑制板面とハンガーフレーム端面のクリアランスにより、一定以上の揺れを確実に抑制するため、筒状の突出部の端面の外径より大きくされている。抑制板２６の一面には、環状のゴム板等の緩衝部材３６が配設されている。   The suppression plate 26 is a flat plate that is larger than the outer diameter of the opposing cylindrical protrusion 24A. The suppression plate 26 is disposed between the end surface of the cylindrical projecting portion 24A and the nut 28 facing the end surface. The suppression plate 26 may be appropriately selected to be a circular flat plate for swinging in an arbitrary direction, or a square flat plate for giving directionality to the swing. The restraint plate 26 is made larger than the outer diameter of the end surface of the cylindrical projecting portion in order to reliably restrain a certain amount of shaking by the clearance between the restraint plate surface and the hanger frame end surface. A buffer member 36 such as an annular rubber plate is disposed on one surface of the suppression plate 26.

抑制板２６の一面とこれに対向するハンガーフレーム１２の上端面との間には、ゴム弾性体２２Ａの筒状の突出部２４Ａによりクリアランス３８が設けられている。抑制板２６の面と対向するナット２８の締め付けにより、ゴム弾性体の筒状の突出部２４Ａは抑制板２６の一面を介して押圧を受ける。圧縮された筒状の突出部２４Ａのゴム弾性力によりクリアランス３８は保持される。クリアランス３８を有することにより、使用時にゴム弾性体の筒状の突出部２４Ａの端面を支点として抑制板２６が吊りボルト１８、ナット２８と共に揺動できる。   A clearance 38 is provided between the one surface of the restraining plate 26 and the upper end surface of the hanger frame 12 facing the restraining plate 24 by a cylindrical projecting portion 24A of the rubber elastic body 22A. By tightening the nut 28 facing the surface of the suppression plate 26, the cylindrical protrusion 24 </ b> A of the rubber elastic body is pressed through one surface of the suppression plate 26. The clearance 38 is held by the rubber elastic force of the compressed cylindrical protrusion 24A. By having the clearance 38, the restraining plate 26 can swing together with the suspension bolt 18 and the nut 28 with the end face of the cylindrical protrusion 24A of the rubber elastic body as a fulcrum at the time of use.

抑制板２６は、筒状の突出部２４Ａの外径より大きい形状であり、地震等の力に対する揺れ等により、一定以上傾動したときその外縁部がハンガーフレーム１２端面に当接し、それ以上の動きを抑制する作用を営む。このため、ハンガーフレーム１２に対する吊りボルト１８の一定以上の揺れが、別途構成の揺れ止め用防振ゴムを使用しなくとも抑制される。クリアランス３８の量に応じて抑制板２６の傾動量が定まるが、ゴム弾性体２２の筒状の突出部２４Ａをナットで伸縮させてクリアランス３８の量を適宜調節できる。   The restraining plate 26 has a shape larger than the outer diameter of the cylindrical projecting portion 24A. When the restraining plate 26 is tilted by a certain amount or more due to an earthquake or the like, its outer edge abuts against the end surface of the hanger frame 12 and moves further. Acts to suppress For this reason, the swing of the suspension bolt 18 with respect to the hanger frame 12 can be suppressed without using an anti-vibration rubber having a separate structure. The amount of tilting of the restraint plate 26 is determined according to the amount of the clearance 38, but the amount of the clearance 38 can be adjusted as appropriate by extending or contracting the cylindrical protrusion 24A of the rubber elastic body 22 with a nut.

抑制板２６の一面とこの一面に対向するハンガーフレーム１２の端面とは揺動により衝突を繰り返す。抑制板２６とハンガーフレーム１２が金属製の場合は、両者が衝突した場合、金属音が発生したり、反撥力が発生し部品の破損につながり易いが、抑制板２６の一面あるいはハンガーフレーム１２の端面のいずれかの面、あるいは両面に設けた緩衝部材により、揺動による抑制板２６とハンガーフレーム１２との衝撃を緩和し、金属音等の騒音発生や衝突の反撥力による部品の破損を防止する。緩衝部材３６としては、環状のゴムシートあるいはスポンジ等が使用されてもよい。   One surface of the restraining plate 26 and the end surface of the hanger frame 12 facing this surface repeatedly collide with each other. In the case where the restraining plate 26 and the hanger frame 12 are made of metal, if they collide with each other, a metal sound is generated or a repulsive force is easily generated, which can easily cause damage to the parts. The shock-absorbing plate 26 and the hanger frame 12 are alleviated by the shock-absorbing member provided on either or both of the end faces, and the damage of the parts due to the generation of noise such as metal noise or the repulsive force of the collision is prevented. To do. As the buffer member 36, an annular rubber sheet or sponge may be used.

なお、抑制板２６は通常時、ワッシャを兼ねるものでもよい。すなわち、抑制板２６は、被締結材にナットやボルト頭がめり込まないようにする、あるいは穴径がボルト径に比べて大きい場合に座面を安定させる場合などに用いられる通常のワッシャの機能を兼ねてもよい。   The suppression plate 26 may also serve as a washer at normal times. In other words, the restraining plate 26 functions as a normal washer used to prevent the nut or bolt head from entering the material to be fastened, or to stabilize the seating surface when the hole diameter is larger than the bolt diameter. It may also serve as.

図２は吊り型防振ゴム１０の動作状況を示す説明図で、図１の上部を示している。
吊り型防振ゴム１０が使用時に地震等により揺れたとき、図２（ａ）、（ｂ）に示すように、ゴム弾性体の筒状の突出部２４Ａの端面を支点として抑制板２６が吊りボルト１８とゴム弾性体２２Ａと共に揺動する。このとき、抑制板２６の外縁部の一部がハンガーフレーム１２の端面に当接すると、そこで吊りボルト１８とゴム弾性体２２Ａの一定以上の動きを抑制する。 FIG. 2 is an explanatory view showing the operating state of the suspension type anti-vibration rubber 10, and shows the upper part of FIG.
When the suspension type anti-vibration rubber 10 is shaken by an earthquake or the like during use, as shown in FIGS. 2 (a) and 2 (b), the restraining plate 26 is suspended with the end face of the cylindrical protrusion 24A of the rubber elastic body as a fulcrum. It swings together with the bolt 18 and the rubber elastic body 22A. At this time, when a part of the outer edge portion of the restraining plate 26 comes into contact with the end surface of the hanger frame 12, the movement of the suspension bolt 18 and the rubber elastic body 22 </ b> A beyond a certain level is restrained there.

＜動作試験例＞
図２に示す吊り型防振ゴムとして、外径５０ｍｍ、肉厚３.２ｍｍの抑制板２６と、Ｍ１０の吊りボルト１８と、これに螺合されるナット２８とを使用して間隔１ｍｍのクリアランス３８を有する吊り型防振ゴムを構成したとき、以下の動作を行なうことが考えられる。すなわち、抑制板２６から距離Ｈだけ離れた位置の最大変位量Ｌを算出したところ、次の数値が得られた。 <Operation test example>
As the suspension-type anti-vibration rubber shown in FIG. 2, a clearance of 1 mm is obtained by using a restraining plate 26 having an outer diameter of 50 mm and a wall thickness of 3.2 mm, a suspension bolt 18 of M10, and a nut 28 screwed to the suspension plate. When the suspension type anti-vibration rubber having 38 is constituted, it is conceivable to perform the following operations. That is, when the maximum displacement L at a position away from the suppression plate 26 by the distance H was calculated, the following numerical value was obtained.

Ｈが約５０ｍｍのとき、Ｌは約４ｍｍ、Ｈが約１００ｍｍのとき、Ｌは約８ｍｍ、Ｈが約１５０ｍｍのときＬは約１２ｍｍである。この範囲の変位量であれば、吊り型防振ゴム１０に支持された被支持物が建築物の側壁に接触あるいは衝突したり落下する等の問題は全く生じないだけでなく、ゴム弾性体２２Ａの防振効果を損なうことも全くない。   When H is about 50 mm, L is about 4 mm, when H is about 100 mm, L is about 8 mm, and when H is about 150 mm, L is about 12 mm. If the amount of displacement is within this range, the supported object supported by the suspension-type anti-vibration rubber 10 will not cause any problems such as contact with or colliding with the side wall of the building or dropping, and the rubber elastic body 22A. There is no loss of the anti-vibration effect.

吊り型防振ゴム１０は、使用時に吊りボルト１８がハンガーフレーム１２に対して揺動しても抑制板２６によりその揺れが止められる。したがって、揺れ止め用防振ゴムを使用することなく、一定以上の揺れを抑制し得ると共に所定の防振効果を発揮する。施工の短縮化やコスト低減につながる。   Even if the suspension bolt 18 swings with respect to the hanger frame 12 during use, the suspension type anti-vibration rubber 10 is prevented from shaking by the restraining plate 26. Therefore, without using anti-vibration rubber for anti-swaying, it is possible to suppress a certain level of vibration and to exhibit a predetermined anti-vibration effect. It leads to shortening of construction and cost reduction.

図３は実施例２の吊り型防振ゴム３９を示す断面図である。図１と共通する部分には同一符号を付して重複説明を省略する。
吊り型防振ゴム３９は、図３に示すように、ゴム弾性体２２Ｂをハンガーフレーム１２の下端面にのみ設け、このゴム弾性体２２Ｂの筒状の突出部２４Ｂの端面に抑制板２６を設けたものである。 FIG. 3 is a cross-sectional view showing the suspension type vibration isolating rubber 39 of the second embodiment. Portions common to those in FIG.
As shown in FIG. 3, the suspension type vibration-proof rubber 39 is provided with a rubber elastic body 22B only on the lower end surface of the hanger frame 12, and a suppression plate 26 is provided on the end surface of the cylindrical protrusion 24B of the rubber elastic body 22B. It is a thing.

この吊り型防振ゴム３９の場合も使用時に地震等により大きな揺れが生じたとき、ハンガーフレーム１２に対して支持ボルト２０とゴム弾性体２２Ｂが揺動する。このとき、支持ボルト２０と共に揺動する抑制板２６の外縁部の一部がハンガーフレーム１２の端面に当接し、支持ボルト２０とゴム弾性体２２Ｂの動きが抑制される。すなわち、吊り型防振ゴム１０と同様の作用効果を奏する。   Also in the case of the suspension type anti-vibration rubber 39, the support bolt 20 and the rubber elastic body 22B swing with respect to the hanger frame 12 when a large shake occurs due to an earthquake or the like during use. At this time, a part of the outer edge portion of the restraining plate 26 that swings together with the support bolt 20 comes into contact with the end face of the hanger frame 12, and the movement of the support bolt 20 and the rubber elastic body 22B is restrained. In other words, the same effect as the suspension type anti-vibration rubber 10 is obtained.

なお、本発明においては、図１に示した吊り型防振ゴム１０におけるゴム弾性体２２Ｂの筒状の突出部２４Ｂの端面にも抑制板２６を設けてもよい。つまり、抑制板２６は、ハンガーフレーム１２の上端側と下端側の両外側にそれぞれ設けてもよい。   In the present invention, the suppression plate 26 may also be provided on the end face of the cylindrical protrusion 24B of the rubber elastic body 22B in the suspension type anti-vibration rubber 10 shown in FIG. That is, the suppression plate 26 may be provided on both outer sides of the upper end side and the lower end side of the hanger frame 12.
