【実施例】 以下実施例を示す図面に基づいて本考案を詳説する。Embodiments The present invention will be described in detail below with reference to the drawings illustrating embodiments.

【0008】 図1において、1,2は間隔部3をもって対向する第1躯体と第2躯体であり 、第1・第2躯体1,2の角部4,5には、ボルト等の固着具により、金属型材 からなる縁材6,6が固着される。In FIG. 1, reference numerals 1 and 2 denote a first body and a second body that face each other with a gap 3 between them. Fasteners such as bolts are attached to the corners 4 and 5 of the first and second bodies 1 and 2, respectively. Thereby, the edge members 6 and 6 made of the metal mold material are fixed.

【0009】 縁材6には、蟻溝状のパッキン保持片部7と、両躯体1,2の内方へ開口する 長手方向凹溝8と、傾斜状の外止水板保持片部9と、が夫々形成され、パッキン 保持片部7にはパッキン10が嵌着される。The edge member 6 includes a dovetail-shaped packing holding piece portion 7, a longitudinal groove 8 that opens inwardly of both the skeletons 1 and 2, and an inclined outer water stop plate holding piece portion 9. , And a packing 10 is fitted to the packing holding piece 7.

【0010】 11は第1躯体1と第2躯体2間を被覆するカバープレートで、間隔部3を外方 から施蓋して遮蔽する。Reference numeral 11 denotes a cover plate that covers the space between the first body 1 and the second body 2, and shields the gap portion 3 by covering it from the outside.

【0011】 カバープレート11の両端縁にはシール材12が取付けされ、第1・第2躯体1, 2の外壁面に密接する。Sealing materials 12 are attached to both end edges of the cover plate 11 and are in close contact with the outer wall surfaces of the first and second bodies 1 and 2.

【0012】 13はカバープレート11を支持する横断面略コの字型の橋絡杆体で、橋絡杆体13 の両端に回転自在に取付けられた係合突出子14,14が、長手方向凹溝8,8に摺 動自在に係合する。Reference numeral 13 denotes a bridging rod body having a substantially U-shaped cross section for supporting the cover plate 11. Engaging projections 14, 14 rotatably attached to both ends of the bridging rod body 13 have longitudinal grooves. 8 and 8 are slidably engaged.

【0013】 なお、第1・第2躯体1,2が変位しない通常状態において、橋絡杆体13は、 カバープレート11の裏面側から見て傾斜した状態(つまり橋絡杆体13の両端が図 1において図面と直交方向に上下にずれた状態)にて、連結具15によって、首振 自在にカバープレート11に取付けられる。In the normal state where the first and second skeletons 1 and 2 are not displaced, the bridging rod 13 is inclined when viewed from the back surface side of the cover plate 11 (that is, both ends of the bridging rod 13 are shown in FIG. In a state of being vertically displaced in the direction orthogonal to the drawing), the connector 15 swingably attaches to the cover plate 11.

【0014】 連結具15は、カバープレート11及び橋絡杆体13の貫孔に挿通するボルト16と、 ワッシャ17と、カバープレート11の裏面と橋絡杆体13の表面に当接する円筒状ス ペーサ18と、ナット部材19を固着したコの字型のスプリング保持具20と、コイル スプリング等の弾発部材21とからなる。The connector 15 includes a bolt 16 inserted through the through holes of the cover plate 11 and the bridging rod body 13, a washer 17, and a cylindrical spacer 18 that abuts against the back surface of the cover plate 11 and the front surface of the bridging rod body 13. And a U-shaped spring holder 20 to which a nut member 19 is fixed, and an elastic member 21 such as a coil spring.

【0015】 ワッシャ17,スペーサ18及び弾発部材21は、ボルト16の軸部に対して外嵌状と なっており、ボルト16をナット部材19に螺着し、橋絡杆体13の裏面とスプリング 保持具20の底面の間に弾発部材21を介装して、弾発的に橋絡杆体13とカバープレ ート11を互いに引寄せる。The washer 17, the spacer 18, and the elastic member 21 are externally fitted to the shaft of the bolt 16, and the bolt 16 is screwed to the nut member 19, and the back surface of the bridging rod 13 and the spring. An elastic member (21) is interposed between the bottom surfaces of the holder (20) to elastically pull the bridging rod (13) and the cover plate (11) together.

【0016】 これにより、地震等にて、第1・第2躯体1,2が、矢印A方向に相対的に変 位しても、連結具15を中心に橋絡杆体13の傾斜角度が変化(つまり連結具15廻り に回転)して変動に追随できる。As a result, even if the first and second frames 1 and 2 are relatively displaced in the direction of arrow A due to an earthquake or the like, the inclination angle of the bridging rod 13 is changed around the connector 15. (That is, rotate around the connector 15) to follow the fluctuation.

【0017】 また、第1・第2躯体1,2が、矢印B方向に相対的に変位しても、橋絡杆体 13とカバープレート11が揺動して変動に追随でき、さらに、第1・第2躯体1, 2が図1において図面と直交方向に相対的にずれても、長手方向凹溝8,8内で 係合突出子14,14が摺動して変動に追随できる。Further, even if the first and second skeletons 1 and 2 are relatively displaced in the direction of the arrow B, the bridging rod 13 and the cover plate 11 can oscillate and follow the fluctuations. Even if the second frames 1 and 2 are displaced relative to each other in the direction orthogonal to the drawing in FIG. 1, the engagement protrusions 14 and 14 can slide in the longitudinal grooves 8 to follow the fluctuation.

【0018】 ところで、カバープレート11の裏面側の第1・第2躯体1,2間には、間隔部 3を内外二重に遮蔽するゴム又は/及びプラスチック製の柔軟な一対の内止水板 22及び外止水板23が介装されている。By the way, between the first and second skeletons 1 and 2 on the back surface side of the cover plate 11, a pair of flexible inner water stop plates made of rubber and / or plastic that shields the gap portion 3 from inside to outside. 22 and an outer water stop plate 23 are interposed.

【0019】 内止水板22の両端部は、縁材6,6と角部4,5の間にアングル材等を介して 挟着され、縁材6,6の両端縁部26,26と内止水板22の両端縁部27,27はアング ル材等に密着する。なお、(図示省略したが)望ましくは、アングル材と内止水 板22の両端縁部27,27の間に、ブチルテープを介装し、気密性を向上し、かつ密 着させる。また、アングル材が角部4,5に無い場合には、ブチルテープを厚く して、第1・第2躯対1,2の凹凸を吸収するのが良い。Both ends of the inner water blocking plate 22 are sandwiched between the edge members 6 and 6 and the corner portions 4 and 5 with an angle member or the like interposed therebetween, and both edge portions 26 and 26 of the edge members 6 and 6 are connected to each other. Both edge portions 27, 27 of the inner water stop plate 22 are in close contact with an angle material or the like. It should be noted that, although not shown, preferably, a butyl tape is interposed between the angle member and the both edge portions 27, 27 of the inner water blocking plate 22 to improve airtightness and tightly adhere. When the angle member is not present at the corners 4 and 5, it is preferable to thicken the butyl tape to absorb the unevenness of the first and second skeletons 1 and 2.

【0020】 また、外止水板23の係合突部24,24は、外止水板保持片部9,9の先端に形成 された係止凹溝25,25に嵌着され、外止水板23の両端縁部が外止水板保持片部9 ,9に密着する。Further, the engaging projections 24, 24 of the outer water stop plate 23 are fitted into the locking recessed grooves 25, 25 formed at the tips of the outer water stop plate holding pieces 9, 9 to provide the outer stop. Both edge portions of the water plate 23 are brought into close contact with the outer water blocking plate holding pieces 9, 1.

【0021】 そして、内外止水板22,23は、夫々、所定曲率で内方に弯曲し、内外止水板22 ,23間には、所定間隔Cで空隙層Pが設けられる。また、内外止水板22,23の材 質は、PVC,CR,エラストマーとするのが望ましい。更には、振動を瞬間的 に熱エネルギーに変更して吸収する特殊イソプレン系ゴムが望ましい。The inner and outer water stop plates 22 and 23 are each curved inward with a predetermined curvature, and a void layer P is provided between the inner and outer water stop plates 22 and 23 at a predetermined interval C. The material of the inner and outer water stop plates 22 and 23 is preferably PVC, CR, or elastomer. Furthermore, a special isoprene-based rubber that absorbs vibration by instantaneously converting it into heat energy is desirable.

【0022】 内外止水板22,23は薄肉となっており、その厚み寸法Tは例えば0.6 〜1.2mm に設定される。The inner and outer water stop plates 22 and 23 are thin, and their thickness dimension T is set to, for example, 0.6 to 1.2 mm.

【0023】 この内外止水板22,23は、通常の止水板として機能するだけでなく、二重とす ることにより、遮音する機能をも兼ね備えており、図2の遮音性能を有している 。なお、図2の透過損失のグラフは、内外止水板22,23の厚み寸法Tを0.8mm に した場合のものを示している。The inner and outer water stop plates 22 and 23 not only function as normal water stop plates, but also have a sound insulating function by being doubled, and have the sound insulation performance of FIG. ing . The graph of transmission loss in FIG. 2 shows the case where the thickness dimension T of the inner and outer water blocking plates 22 and 23 is 0.8 mm.

【0024】 図3は、外止水板は同じであるが、内止水板の材質を重量のある金属として鉛 を使用し、内止水板の厚み寸法Tを1mmにした場合(ー般に遮音性能を高めるに は鉛のように重量を重くする必要があるため)の透過損失のグラフである。In FIG. 3, although the outer water blocking plate is the same, when lead is used as the material of the inner water blocking plate as a heavy metal and the thickness dimension T of the inner water blocking plate is set to 1 mm (generally, In order to improve the sound insulation performance, it is necessary to increase the weight like lead).

【0025】 この透過損失の値が大きいほど遮音性能が高くなるが、図2と図3を比較する と、周波数が500Hz を越える範囲では、図2と図3の透過損失はほぼ同等の値を 示しており、遮音性能に遜色がないことがわかる。The larger the value of this transmission loss, the higher the sound insulation performance. However, comparing FIG. 2 and FIG. 3, in the range where the frequency exceeds 500 Hz, the transmission loss of FIG. 2 and FIG. As shown, it can be seen that the sound insulation performance is comparable.

【0026】 人の耳での可聴範囲の音において、遮音上問題となるのは中音域以上で(通常 、耳の感度は周波数が増加するにつれて感度も増加し、3〜4kHz で最も感度が 高くなり、音圧レベルの低い音でも聞こえるようになるため)低音域において高 い遮音性能はあまり必要ではない。In the sound in the audible range of the human ear, the problem of sound insulation is in the mid-range or higher (usually, the sensitivity of the ear increases as the frequency increases, and the sensitivity is highest at 3 to 4 kHz). Therefore, a high sound insulation performance in the low sound range is not necessary so much even if the sound has a low sound pressure level.

【0027】 従って、図1に示す本考案の内外止水板22,23の構成をもってすれば、遮音性 能の優れた図3に劣らない遮音効果を発揮でき、しかも、内外止水板22,23が、 エラストマーシート又は/及びプラスチックシートであるから、軽量で、取付け が極めて容易となる。Therefore, with the structure of the inner and outer water stop plates 22 and 23 of the present invention shown in FIG. 1, it is possible to exhibit the sound insulation effect which is excellent in sound insulation performance and is not inferior to that of FIG. Since 23 is an elastomer sheet and / or a plastic sheet, it is lightweight and extremely easy to mount.

【0028】 なお、図1に示す空隙層Pの間隔Cが不十分であると、空隙層P内の空気層や 内外止水板22,23の共振及び音の波長等の関係から、遮音性能が悪くなるため、 間隔Cを25mmから60mmの範囲に設定する。If the space C between the air gap layers P shown in FIG. 1 is insufficient, the sound insulation performance may be improved due to the relationship between the air layer in the air gap layer P, the resonance of the inner and outer water stop plates 22 and 23, the wavelength of sound, and the like. Therefore, set the distance C to the range of 25mm to 60mm.

【0029】 また、本考案の伸縮継手は、隙間が生じにくい構造となっているので、音が漏 れることがなく遮音性能が良好である。Further, since the expansion joint of the present invention has a structure in which a gap is unlikely to occur, sound is not leaked and sound insulation performance is good.

【0030】[0030]

【考案の効果】[Effect of the device]

本考案は上述の如く構成されているので、次に記載するような著大な効果を奏 する。 Since the present invention is constructed as described above, it has the following great effects.

【0031】 可撓性のあるゴム又は/及びプラスチック製の内外止水板22,23によって高い 遮音性能を実現でき、又、内外止水板22,23は軽量であるので施工が極めて容易 となる。特に軽量化が要求される建物等に好適である。High sound insulation performance can be realized by the flexible rubber and / or plastic inner and outer water stop plates 22 and 23, and the inner and outer water stop plates 22 and 23 are lightweight, which makes the installation extremely easy. .. It is particularly suitable for buildings and the like that require weight reduction.
