Description
【０００１】[0001]
本考案は、リブ付管用のパッキンに関し、詳しくは外周面に多数の環状リブを 有するリブ付管同士を接続する際に用いられるリング状のパッキンに関する。 The present invention relates to a packing for ribbed pipes, and more particularly to a ring-shaped packing used when connecting ribbed pipes having a large number of annular ribs on the outer peripheral surface.
【０００２】[0002]
近年、図３に示すように、管体の外周面に多数の環状リブ１を突設した、いわ ゆるリブ付管２が提案され、地中埋設用配管として採用されつつある。このリブ 付管２同士を接続する際には、従来の通常の合成樹脂管（プレーン管）同士を接 続するときと同様に、一方のリブ付管２の開口部２ａを拡開するとともに、他方 のリブ付管２の環状リブ１間にリング状のパッキン３を装着し、両者を嵌合させ る工法により行われている。 In recent years, as shown in FIG. 3, a so-called ribbed pipe 2 in which a large number of annular ribs 1 are projectingly provided on the outer peripheral surface of a pipe body has been proposed and is being adopted as a pipe for underground burial. When connecting the ribbed pipes 2 to each other, the opening 2a of one ribbed pipe 2 is widened as in the case of connecting the conventional ordinary synthetic resin pipes (plain pipes) to each other. The ring-shaped packing 3 is attached between the annular ribs 1 of the other ribbed tube 2 and the two are fitted together.
【０００３】[0003]
しかしながら、上記方法では、パッキン３をリブ付管２の環状リブ１間に装着 する際、パッキン３の抜けを防止するために、パッキン３を引張って幾つかの環 状リブ１を乗り越させなければならず、作業性に難点があった。 However, in the above method, when the packing 3 is mounted between the annular ribs 1 of the ribbed tube 2, the packing 3 must be pulled to pass over some of the annular ribs 1 in order to prevent the packing 3 from coming off. However, there was a problem in workability.
【０００４】 そこで本考案は、シール性を損なうことなく、リブ付管への装着を容易に行う ことができるパッキンを提供することを目的としている。Therefore, an object of the present invention is to provide a packing that can be easily mounted on a ribbed pipe without impairing the sealing property.
【０００５】[0005]
上記した目的を達成するため、本考案のリブ付管用のパッキンは、リブ付管の 環状リブの両側に配置される二つの膨出部と、該膨出部の外周部を接続するとと もに両膨出部間の環状リブの外周部を覆う薄肉部とを有することを特徴としてい る。 In order to achieve the above-mentioned object, the packing for a ribbed pipe of the present invention connects two bulging portions arranged on both sides of the annular rib of the ribbed pipe and the outer peripheral portion of the bulging portion. It is characterized by having a thin portion covering the outer peripheral portion of the annular rib between the both bulging portions.

【実施例】 以下、本考案の一実施例を図面に基づいて説明する。図１はパッキンを装着し たリブ付管の要部を示す断面図、図２はパッキンを装着する手順を示す説明図で ある。Embodiment An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a cross-sectional view showing a main part of a ribbed tube with a packing attached, and FIG. 2 is an explanatory view showing a procedure for installing the packing.
【０００７】 本実施例に示すパッキン１０は、一つの環状リブ１の両側に配置される大小二 つの膨出部１１，１２と、該膨出部１１，１２の外周部を接続する薄肉部１３と 、小さな膨出部１２の外周側から延設されて他の環状リブ１の外周部を覆う覆い 部１４とから形成されている。The packing 10 shown in this embodiment has two large and small bulging portions 11 and 12 arranged on both sides of one annular rib 1 and a thin wall portion 13 connecting the outer peripheral portions of the bulging portions 11 and 12. It is formed of a cover portion 14 extending from the outer peripheral side of the small bulging portion 12 and covering the outer peripheral portion of another annular rib 1.
【０００８】 このパッキン１０は、図２（イ）に示すように、断面をリブ付管２への装着時 の形状に対応して大小二つの膨出部１１，１２が対峙するようにリング状に製造 される。また、パッキン１０の外径は、環状リブ１の外径よりも大きく形成され ている。As shown in FIG. 2 (a), the packing 10 has a ring-shaped cross section so that two large and small bulging portions 11 and 12 face each other in correspondence with the shape when mounted on the ribbed tube 2. To be manufactured. Moreover, the outer diameter of the packing 10 is formed larger than the outer diameter of the annular rib 1.
【０００９】 そして、パッキン１０をリブ付管２に装着するには、まず、図２（ロ）に示す ように、薄肉部１３部分で膨出部１２を外周側にめくり返した後、図２（ハ）に 示すように、大きな膨出部１１をリブ付管２端部外周に装着し、該膨出部１１を 端部の環状リブ１の外面に当接させる。次いで、図２（ハ）想像線に示すように 、小さな膨出部１２を折り戻して、該膨出部１２を環状リブ１，１間に嵌合させ る。To attach the packing 10 to the ribbed tube 2, first, as shown in FIG. 2B, after the bulging portion 12 is turned back to the outer peripheral side in the thin portion 13, As shown in (c), a large bulging portion 11 is attached to the outer periphery of the end portion of the ribbed tube 2, and the bulging portion 11 is brought into contact with the outer surface of the annular rib 1 at the end portion. Next, as shown in the imaginary line in FIG. 2C, the small bulging portion 12 is folded back and the bulging portion 12 is fitted between the annular ribs 1, 1.
【００１０】 これにより、小さな膨出部１２が端部の環状リブ１の側面に当接してパッキン １０の抜止めとなり、パッキン１０が固定される。また、薄肉部１３と覆い部１ ４とが、環状リブ１の外周部を覆い、両膨出部１１，１２の外周面と薄肉部１３ 及び覆い部１４とが他方のリブ付管２の内面に当接してシールを行う。As a result, the small bulging portion 12 comes into contact with the side surface of the annular rib 1 at the end to prevent the packing 10 from coming off, and the packing 10 is fixed. Further, the thin portion 13 and the covering portion 14 cover the outer peripheral portion of the annular rib 1, and the outer peripheral surfaces of both the bulging portions 11 and 12 and the thin portion 13 and the covering portion 14 are the inner surface of the other ribbed tube 2. Abut and seal.
【００１１】 上記のように、二つの膨出部１１，１２を薄肉部１３で接続したことにより、 パッキン１０の装着作業性を大幅に向上できる。また、めくり返しや折り戻しも 、薄肉部１３部分で行うので容易に行うことができる。As described above, by connecting the two bulged portions 11 and 12 with the thin portion 13, the workability of mounting the packing 10 can be significantly improved. Further, turning over and folding back can be easily performed because they are performed in the thin portion 13 portion.
【００１２】 なお、上記のように覆い部１４を設けることにより、シール性を向上させるこ とができるが、該覆い部１４を設けなくても必要なシール性能を得ることが可能 である。また、パッキン１０は、従来からこの種のパッキンに用いられている材 料で形成でき、膨出部１１，１２の大きさや薄肉部１３の厚みは、リブ付管２の 径や環状リブ１の形状、パッキン１０の各部の硬さなどに応じて適宜最適な範囲 に設定することができる。It should be noted that by providing the cover portion 14 as described above, it is possible to improve the sealing performance, but it is possible to obtain the necessary sealing performance without providing the cover portion 14. Further, the packing 10 can be formed of the material conventionally used for this kind of packing, and the size of the bulging portions 11 and 12 and the thickness of the thin portion 13 are different from those of the ribbed tube 2 and the annular rib 1. The optimum range can be set according to the shape, the hardness of each part of the packing 10, and the like.
【００１３】[0013]
以上説明したように、本考案のリブ付管用のパッキンは、二つの膨出部の外周 部を薄肉部で接続した形状としたから、リブ付管にパッキンを装着する際に環状 リブを乗り越させる必要がなくなり、パッキンを容易に装着することができる。 As described above, the packing for the ribbed pipe of the present invention has a shape in which the outer peripheral portions of the two bulging portions are connected by a thin portion, so that when the packing is attached to the ribbed pipe, the annular rib is ridden over. It is not necessary to do so, and the packing can be easily attached.
