Description

本発明は、配管と、フランジ型の配管接続部を持つ管継手との接続部分、或いは配管をソケットを介して接続する形式の配管接続部を持つ管継手との接続部分に適用されて配管系統に遮音と防熱を施す配管接続部用の遮音カバーに関する。   The present invention is applied to a connection part between a pipe and a pipe joint having a flange-type pipe connection part, or a connection part between a pipe joint having a pipe connection part of a type in which the pipe is connected via a socket. The present invention relates to a sound insulation cover for a pipe connection part that performs sound insulation and heat insulation on a pipe.

従来、既設の排水管や排水管継手に生じる流水による騒音を防止するため、遮音シートを排水管や継手に巻き付けることが行われている。この遮音シートとして、ポリ塩化ビニルシートとグラスウールを積層したシートや、このシートのポリ塩化ビニルの層の表面に、更にアルミ箔とガラス繊維のメッシュを積層したいわゆるアルミガラスクロスを貼り付けた遮音シートが知られている。   Conventionally, in order to prevent noise caused by flowing water generated in an existing drain pipe or drain pipe joint, a sound insulating sheet is wound around the drain pipe or joint. As this sound insulation sheet, a sheet in which a polyvinyl chloride sheet and glass wool are laminated, or a sound insulation sheet in which a so-called aluminum glass cloth in which an aluminum foil and a glass fiber mesh are further laminated is attached to the surface of the polyvinyl chloride layer of this sheet. It has been known.

既設の配管や継手に対するこれらの遮音シートの取り付けは、人手により行われ、一般的には所定の寸法に裁断した遮音シートにより配管等を覆い、これをバンドや接着テープなどの固定手段により固定して配管等の騒音を封じ込んでいる。遮音シートはシート状あるいはテープ状に裁断され、必要な場合は遮音シートに切り込みを入れることで取り付け箇所の表面の凹凸に沿った遮音被覆を行えるようにしている。しかし、フランジ型の配管接続部を備えた排水管継手は、締め付けボルトを挿通するためにフランジ部分が大きく側方へ突出しているので、既設配管の背後に手を回し込んでシート状やテープ状の遮音シートによりフランジ部分が露出しないように覆うことは容易でなかった。   These sound insulation sheets are attached to existing pipes and joints by hand. Generally, the sound insulation sheets cut into predetermined dimensions are used to cover the pipes and the like, and are fixed by fixing means such as bands or adhesive tape. The pipes and other noise are contained. The sound insulation sheet is cut into a sheet shape or a tape shape, and if necessary, the sound insulation sheet is cut so that a sound insulation coating can be performed along the unevenness of the surface of the attachment location. However, the drainage pipe joint with flange-type pipe connection part has a flange part that protrudes to the side in order to insert the tightening bolt. It was not easy to cover the flange portion so as not to be exposed by the sound insulation sheet.

また、遮音のためには排水管継手の上記接続部分以外の部分が露出しないように遮音シートで被覆することが望ましいが、排水管継手の設置状態によってその露出部分の長さが変わるため、この露出部分には別途に遮音シートを巻く作業が必要でその分被覆作業時間が長くなる不都合があった。さらに差込型の接続部分を有する排水管継手は、継手よりも側方へ大きく膨出したソケットを介して配管に接続されるから、前記の場合と同様にこの接続部分を遮音シートで覆う作業は容易でなかった。   In addition, for sound insulation, it is desirable to cover the drainage pipe joint with a sound insulation sheet so that other parts than the above-mentioned connection parts are not exposed. However, the length of the exposed part changes depending on the installation state of the drainage pipe joint. The exposed portion needs to be separately wrapped with a sound insulation sheet, and there is an inconvenience that the covering operation time becomes longer. Furthermore, since the drainage pipe joint having a plug-in connection part is connected to the pipe through a socket that bulges to the side of the joint, cover the connection part with a sound insulation sheet as in the case described above. Was not easy.

特開2010−236689号公報JP 2010-236689 A

本発明は、フランジ型やソケットを介して配管を接続する形式の配管接続部を持つ管継手の接続部分に、簡単に被覆でき、しかも安価に製作可能な遮音カバーを提供することを課題とするものである。   It is an object of the present invention to provide a sound insulation cover that can be easily covered and can be manufactured at a low cost on a connection portion of a pipe joint having a pipe connection portion of a type for connecting a pipe via a flange type or a socket. Is.

本発明では、アルミガラスクロスと合成樹脂シートと無機繊維シートを順次に重層して形成した遮音性シートにより、フランジ型の管継手と配管との接続部分の上方部分を周回して被覆する円弧状に湾曲した帯状の上方カバーと、その接続部分の下方部分を周回して被覆する円弧状に湾曲した帯状の下方カバーを形成し、これらのカバーの外円側の円弧状の縁部を互いに同曲率且つ同長に形成すると共にアルミガラスクロスを貼着して互いに接続し、該上方カバーの外円側の円弧状の縁部に沿ってこれらカバーの接続箇所を隠す帯状の遮音性の目隠し部材を揺動自在に設けたことにより、上記の課題を解決するようにした。上方カバーおよび下方カバーの長さ方向の端部に、上記周回した被覆状態を維持するための接着剤を塗布した接合片を設けておくと被覆作業がより簡単になる。
また、アルミガラスクロスと合成樹脂シートと無機繊維シートを順次に重層して形成した遮音性シートにより、フランジ型の管継手と配管の接続部分の上方部分を周回して被覆する円弧状に湾曲した帯状の上方カバーと、その接続部分の下方部分を周回して被覆する円弧状に湾曲した帯状の下方カバーを形成し、これらのカバーの外円側の円弧状の縁部を同長に形成すると共にアルミガラスクロスを貼着して互いに接続し、該上方カバーの内円側の円弧状の縁部に、円弧状に湾曲する帯状の調整カバーに形成され且つ該上方カバーの内円側の縁部と同長に形成された円弧状の縁部をアルミガラスクロスにより接続し、該調整カバーが上記接続部分以外の該管継手の露出部分を被覆するようにすることによっても上記の課題が解決される。この調整カバーには、円弧状の縁部に沿った方向に破線状の切込線を形成し、この切込線に沿って切断することにより該調整カバーの帯状の幅を調節できるようにすることで施工が容易になり、継手の施工状態によって変化する継手下方の各種の露出部分を被覆する作業が一種類の遮音カバーで対応できるようになる。管継手は、フランジ型管継手のように側方へ突出した構成のソケットを介して配管に接続する形式の差込型の管継手で構成することも可能である。
In the present invention, the sound insulation sheet formed by sequentially layering an aluminum glass cloth, a synthetic resin sheet, and an inorganic fiber sheet wraps around the upper portion of the connection portion between the flange-type pipe joint and the pipe. A belt-shaped upper cover that is curved in a circular arc and a belt-shaped lower cover that circulates around and covers the lower part of the connecting portion, and the arc-shaped edges on the outer circle side of these covers are the same. A band-shaped sound-insulating blindfold member that is formed to have the same curvature and the same length and is bonded to each other by sticking an aluminum glass cloth, and conceals the connecting portion of the cover along the arc-shaped edge on the outer circle side of the upper cover The above-mentioned problems are solved by providing the oscillating member freely. If the joining piece which apply | coated the adhesive agent for maintaining the said surrounding covering state is provided in the edge part of the length direction of an upper cover and a lower cover, covering operation will become easier.
In addition, the sound insulation sheet formed by sequentially layering aluminum glass cloth, synthetic resin sheet, and inorganic fiber sheet is curved in an arc shape that wraps around and covers the upper part of the connection part of the flange type pipe joint and piping. A band-shaped upper cover and a band-shaped lower cover curved around the lower part of the connecting portion to be covered are formed, and the arc-shaped edges on the outer circle side of these covers are formed to have the same length. And an aluminum glass cloth attached to each other, connected to each other, formed on a circular arc-shaped edge on the inner circle side of the upper cover, and formed on a belt-shaped adjustment cover curved in an arc shape, and an edge on the inner circle side of the upper cover The above-mentioned problem can also be solved by connecting arc-shaped edges formed in the same length as the portion with an aluminum glass cloth so that the adjustment cover covers the exposed portion of the pipe joint other than the connection portion. Is done. The adjustment cover is formed with a dashed cut line in the direction along the arcuate edge, and the band width of the adjustment cover can be adjusted by cutting along the cut line. Thus, the construction is facilitated, and the work of covering various exposed portions below the joint, which varies depending on the joint construction state, can be handled with one type of sound insulation cover. A pipe joint can also be comprised with the type of a plug-in type pipe joint of the type connected to piping via the socket of the structure protruded to the side like a flange type pipe joint.

本発明によるときは、上部カバーと下部カバーの外円側の円弧状の縁部を同長とし、そこをヒンジ部により互いに接続したので、上部カバーと下部カバーはヒンジ部を中心として立体形に開くことができ、そのまま管継手のフランジ型接続部へかぶせることができ、接合片などの簡単な固定手段を使用して継手や配管に固定できる。これら上下カバーのつなぎ目には遮音性の目隠し部材が設けられてつなぎ目を塞いでいるので、つなぎ目の隙間からの音漏れが防止される。遮音カバーの表面にはアルミガラスクロスを重層してあるから防水性がよく、グラスウールやロックウールなどの無機質繊維シートが吸水状態になることを防げてカビなどの発生を防止できるとともに遮音カバーの引張強度も向上するので施工時におけるカバーの損傷を防止でき、特別な素材を使用しないので安価に製造できる。   According to the present invention, since the arc-shaped edges on the outer circle side of the upper cover and the lower cover have the same length and are connected to each other by the hinge part, the upper cover and the lower cover have a three-dimensional shape with the hinge part as the center. It can be opened as it is, and can be directly applied to the flange-type connection part of the pipe joint, and can be fixed to the joint or pipe using a simple fixing means such as a joining piece. A sound-insulating blindfold member is provided at the joint between the upper and lower covers to close the joint, so that sound leakage from the gap between the joints is prevented. Since the surface of the sound insulation cover is covered with aluminum glass cloth, it is waterproof and can prevent the generation of mold by preventing the inorganic fiber sheet such as glass wool and rock wool from absorbing water. Since the strength is improved, damage to the cover during construction can be prevented, and since no special material is used, it can be manufactured at low cost.

さらに該上方カバーの内円側の円弧状の縁部に沿って、円弧状に湾曲した帯状の調整カバーの内円側の円弧状の縁部を接続し、該調整カバーが該管継手の下部周囲を被覆することで、該上方カバーでは覆いきれない管継手の下方部分を覆って遮音することができ、この調整カバーに円弧状の縁部に沿った方向に破線状の切込線を形成し、この切込線に沿って切断可能とすることにより該調整カバーの幅を調節して管継手の下方部分の実際の露出長さに簡単に適応させることができる。   Further, along the arcuate edge on the inner circle side of the upper cover, the arcuate edge on the inner circle side of the belt-like adjustment cover curved in an arc shape is connected, and the adjustment cover is connected to the lower part of the pipe joint. By covering the periphery, the lower part of the pipe joint that cannot be covered by the upper cover can be covered and sound insulation can be made, and a broken cut line is formed in this adjustment cover along the arcuate edge. By making it possible to cut along the cut line, the width of the adjustment cover can be adjusted to easily adapt to the actual exposed length of the lower portion of the pipe joint.

本発明の構成によれば、フランジ型以外の管継手であっても、例えば側方へ突出した部分を持ったソケットを介して配管に接続される形式の差込型の管継手の接続部分の遮音カバーとしても利用できる。   According to the configuration of the present invention, even in a pipe joint other than the flange type, for example, a connection part of a plug-in type pipe joint of a type that is connected to a pipe via a socket having a side protruding part. It can also be used as a sound insulation cover.

本発明を実施するための形態を別紙図面に基づき説明すると、図1ないし図3において符号1は遮音カバー、符号2は円弧状に湾曲した帯状の上方カバーを示す。この上方カバー2にはアルミガラスクロスのテープからなるヒンジ部3により接合された湾曲した帯状の下方カバー4が取り付けられる。これらの上方カバー2および下方カバー4は、図4に示したように、アルミ箔とガラス繊維のメッシュを重層した構成のアルミガラスクロス5と、塩化ビニルなどの吸振性のある合成樹脂シート6と、グラスウールなどの吸音性のある無機繊維シート7を順次に重層して形成した遮音性カバーで構成される。これら上方カバー2と下方カバー4はその帯状幅が多少相違し、その外円側の円弧状の縁部8、9を互いに同曲率且つ同長に形成した。   A mode for carrying out the present invention will be described with reference to the accompanying drawings. In FIGS. 1 to 3, reference numeral 1 denotes a sound insulation cover, and reference numeral 2 denotes a belt-like upper cover curved in an arc shape. A curved belt-like lower cover 4 joined by a hinge portion 3 made of an aluminum glass cloth tape is attached to the upper cover 2. As shown in FIG. 4, the upper cover 2 and the lower cover 4 are composed of an aluminum glass cloth 5 having a structure in which an aluminum foil and a glass fiber mesh are overlaid, and a synthetic resin sheet 6 having a vibration absorbing property such as vinyl chloride. The sound-insulating cover is formed by sequentially layering sound absorbing inorganic fiber sheets 7 such as glass wool. The upper cover 2 and the lower cover 4 have slightly different band widths, and arc-shaped edges 8 and 9 on the outer circle side are formed with the same curvature and the same length.

この遮音カバー1は、上方カバー2と下方カバー4の内円側の縁部17、18を離反する方向へ引き離すと、ヒンジ部3を中心として図5に示したような提灯形あるいは算盤玉のような立体形状に開く。上方カバー2の円弧状の縁部8に沿ってアルミガラスクロスのテープにより揺動自在に設けた遮音性の帯状の目隠し部材19は、上下カバー2、4が立体形状に開かれたときに外円側の縁部8、9の接続箇所の隙間を隠して遮音性を向上させ、同時に隙間を防水する作用を営む。実施例では、目隠し部材19に吸振性のある合成樹脂シートにアルミガラスクロスを積層したものを使用したが、遮音性シートと同じ構成のものを使用してもよい。20は上下カバー2、4の両端部に設けた接着剤を塗布した接合片である。   The sound insulation cover 1 is formed of a lantern or abacus ball as shown in FIG. 5 with the hinge portion 3 as the center when the inner circular side edges 17 and 18 of the upper cover 2 and the lower cover 4 are separated away from each other. Open in a three-dimensional shape. A sound-insulating band-shaped blindfold member 19 provided swingably with an aluminum glass cloth tape along the arcuate edge 8 of the upper cover 2 is removed when the upper and lower covers 2 and 4 are opened in a three-dimensional shape. The gap between the connecting portions of the edge portions 8 and 9 on the circle side is hidden to improve sound insulation, and at the same time, the gap is waterproofed. In the embodiment, the blindfold member 19 is formed by laminating an aluminum glass cloth on a synthetic resin sheet having a vibration absorbing property, but the same structure as the sound insulating sheet may be used. Reference numeral 20 denotes a joining piece coated with an adhesive provided on both ends of the upper and lower covers 2 and 4.

フランジ型の管継手10は、図6に示すように、配管11の接続部分12の外周に環状のゴム輪13が設けられ、配管11をこのゴム輪13を介して挿通し、フランジ14と対向した環状の押輪15をボルト16にてフランジ14へ締め付けることにより配管11を接続するもので、上方カバー2はこの接続部分12のフランジ14よりも上方の部分を周回して被覆し、下方カバー4は接続部分12の下方の部分を周回して被覆する。従来は、既存の配管に対する遮音性シートの被覆作業において、このフランジ14が配管経路から側方に大きく突出するためにこの箇所の被覆作業が困難であったが、本発明の遮音カバー1は図5に見られるように中間部が膨らんだ算盤玉のような立体形状に開くことができるから、そのまま接続部分12に回し込んで隙間なく簡単に遮音の被覆をすることができる。なお、図示の例では、フランジ型の管継手10を床スラブ22の貫通孔23に配置してその周囲にモルタル24を充填することにより固定した。配管11には鋼管製、合成樹脂製のものあるいは合成樹脂管をモルタルで被覆した耐火二層管を使用してもよく、この場合、接続部分12にはフランジ14と押輪15の間に生じる隙間を耐火性テープで塞ぐことが望ましい。   As shown in FIG. 6, the flange-type pipe joint 10 is provided with an annular rubber ring 13 on the outer periphery of the connection portion 12 of the pipe 11, and the pipe 11 is inserted through the rubber ring 13 to face the flange 14. The pipe 11 is connected by tightening the annular push wheel 15 to the flange 14 with a bolt 16. The upper cover 2 wraps around and covers the portion of the connecting portion 12 above the flange 14, and the lower cover 4. Wraps around the lower part of the connecting part 12. Conventionally, in the covering operation of the sound insulation sheet on the existing piping, since this flange 14 protrudes greatly from the piping path to the side, it is difficult to cover this portion, but the sound insulating cover 1 of the present invention is shown in FIG. As can be seen from FIG. 5, it can be opened in a three-dimensional shape like an abacus ball with an expanded middle portion, so that it can be directly turned into the connecting portion 12 and covered with sound insulation without gaps. In the example shown in the figure, the flange-type pipe joint 10 is disposed in the through hole 23 of the floor slab 22 and is fixed by filling a mortar 24 therearound. The pipe 11 may be made of a steel pipe, a synthetic resin, or a refractory double-layer pipe coated with a synthetic resin pipe with mortar. In this case, a gap formed between the flange 14 and the presser wheel 15 is formed in the connecting portion 12. It is desirable to close the surface with fireproof tape.

図8および図9はその被覆作業の具体例の説明図であり、立体形状に開いた遮音カバー1の一端側を接合片20により継手10と配管11に固定し、他端側を一端側へ重ねて接合片20で固定する。そしてその重ね部分および各内円側の縁部17、18にも図7のようにテープ21を貼ると、密閉状態で接続部分12を遮音カバー1で被覆できる。この被覆作業はテープ21の貼り付け作業が主体であるから、短時間で簡単に施工可能である。なお、配管11は鋼管や耐火二層管のような耐火性のものであることが好ましい。   FIG. 8 and FIG. 9 are explanatory diagrams of specific examples of the covering operation. One end side of the sound insulation cover 1 opened in a three-dimensional shape is fixed to the joint 10 and the pipe 11 by the joining piece 20, and the other end side is directed to one end side. It is overlapped and fixed with the joining piece 20. When the tape 21 is applied to the overlapping portions and the inner circular edge portions 17 and 18 as shown in FIG. 7, the connection portion 12 can be covered with the sound insulating cover 1 in a sealed state. Since this covering work is mainly a sticking work of the tape 21, it can be easily constructed in a short time. In addition, it is preferable that the piping 11 is a fireproof thing like a steel pipe or a fireproof double layer pipe.

図10ないし図16は、本発明の他の実施例を示したもので、上方カバー2と下方カバー4の外円側の円弧状で同長の縁部8、9を互いに突き合わせてアルミガラスクロスのテープ21を貼ることにより概略筒形の立体に形成し、上方カバー2の内円側の円弧状の縁部25に更に調整カバー26を接続して遮音カバー1に構成した。この調整カバー26は、上方カバー2や下方カバー4と同様のアルミ箔とガラス繊維のメッシュを重層した構成のアルミガラスクロス5と、塩化ビニルなどの吸振性のある合成樹脂シート6と、グラスウールなどの吸音性のある無機繊維シート7を順次に重層して形成した構成の帯状且つ円弧状に湾曲した遮音性シートからなり、この調整カバー26の円弧状の内円側の縁部27を、上方カバー2の内円側の円弧状の縁部25と同長に形成し、図15に示したように、これらの縁部25、27を突き合わせてアルミガラスクロスのテープ21で接続することにより図10に見られるような全体が花瓶状の立体に形成した。   FIGS. 10 to 16 show another embodiment of the present invention. The upper cover 2 and the lower cover 4 are arcuate on the outer circle side, and the edges 8 and 9 of the same length are brought into contact with each other to form an aluminum glass cloth. The sound insulation cover 1 was constructed by connecting an adjustment cover 26 to the arcuate edge 25 on the inner circle side of the upper cover 2. The adjustment cover 26 includes an aluminum glass cloth 5 having a structure in which the same aluminum foil and glass fiber mesh as the upper cover 2 and the lower cover 4 are laminated, a synthetic resin sheet 6 having a vibration absorbing property such as vinyl chloride, and glass wool. The sound-absorbing inorganic fiber sheet 7 is sequentially laminated to form a band-like and arc-shaped sound insulation sheet that is curved, and the arc-shaped inner circle side edge 27 of the adjustment cover 26 is The cover 2 is formed to have the same length as the arc-shaped edge 25 on the inner circle side, and as shown in FIG. 15, the edges 25 and 27 are brought into contact with each other and connected with the tape 21 of an aluminum glass cloth. As shown in FIG. 10, the whole was formed into a vase-like solid.

この調整カバー26には、図11に見られるように、表裏を貫通した破線状の切込線28が円弧状の縁部27に沿った方向に形成されており、この切込線28に沿って調整カバー26を破断することによりその帯状の幅寸法を調整できるようにした。建築物の構造によって床スラブ22の厚さが異なり、これに伴い床スラブ22を貫通して設けられた管継手10が床スラブ22の下方へ露出する部分の長さ29も様々に異なるため、この露出部分を覆う調整カバー26の幅は長さ29に合わせて調整する必要があるが、切込線28を設けておくことでナイフなどで簡単にその調整を行えるから様々な露出部分の長さ29に適合させることができる。   As shown in FIG. 11, the adjustment cover 26 is formed with a broken cut line 28 penetrating the front and back in a direction along the arcuate edge 27, and along the cut line 28. Then, the belt-like width dimension can be adjusted by breaking the adjustment cover 26. Since the thickness of the floor slab 22 varies depending on the structure of the building, and the length 29 of the portion where the pipe joint 10 provided through the floor slab 22 is exposed below the floor slab 22 varies accordingly. The width of the adjustment cover 26 that covers the exposed portion needs to be adjusted according to the length 29. However, since the adjustment can be easily performed with a knife or the like by providing the cut line 28, the length of various exposed portions can be adjusted. Can be adapted.

この調整カバー26を備えた形式の遮音カバー1は、図10のような立割れした立体形を保有するので、施工に際しては接続部分12の周囲から囲むように包み込み、その立割れ部分をアルミガラスクロスのテープ21で図14に示すように塞ぐことで簡単に取り付けできる。   Since the sound insulation cover 1 of the type provided with the adjustment cover 26 has a three-dimensional shape that is vertically cracked as shown in FIG. 10, it is wrapped around the connection portion 12 at the time of construction, and the cracked portion is made of aluminum glass. It can be easily attached by closing with a cross tape 21 as shown in FIG.

図14に示した実施例は、図16に明示したように管継手10の接続口を差込型に形成した例を示し、この場合は継手の側方へ突出した部分を持つソケット30を介して配管11に接続するようにした。なお、この実施例において管継手10は金属製、配管11も金属製としたが、配管11を合成樹脂管や耐火二層管としてもよい。   The embodiment shown in FIG. 14 shows an example in which the connection port of the pipe joint 10 is formed as an insertion type as clearly shown in FIG. 16, and in this case, the socket 30 having a portion protruding to the side of the joint is provided. And connected to the pipe 11. In this embodiment, the pipe joint 10 is made of metal and the pipe 11 is also made of metal. However, the pipe 11 may be made of a synthetic resin pipe or a fireproof double-layer pipe.
