Abstract
Description
本発明は、破損した配管を補修する際に用いられる管補修用連結部材に関するものである。 The present invention relates to a pipe repair connecting member used when repairing a damaged pipe.
従来から、例えば割りカラーと称される管補修用連結部材が提供されている(例えば、特許文献1,2参照)。該割りカラーは、地中に埋設された配管に亀裂や割れが生じたときに該配管を補修するものであり、一対の半円筒形をなす半割部材で構成されている。そして、接続すべき被接続管同士の接続部の外形に対応する内面形状とされた半割部材の内周面に接着剤を塗布し、該一対の半割部材を前記接続部に挟着し、さらに公知の番線によって該一対の半割部材の外周を強固に締め付けて該被接続管同士を接続固定するものである。 Conventionally, for example, a pipe repair connecting member called a split collar has been provided (see, for example, Patent Documents 1 and 2). The split collar repairs the pipe when cracks or cracks occur in the pipe buried in the ground, and is composed of a pair of half-cylindrical members. Then, an adhesive is applied to the inner peripheral surface of the halved member having an inner surface shape corresponding to the outer shape of the connection portion between the connected pipes to be connected, and the pair of halved members are sandwiched between the connection portions. Further, the pipes to be connected are connected and fixed by firmly tightening the outer peripheries of the pair of half members by a known wire.
しかしながら、従来の割りカラーは塩ビ材料で射出成形された成形品が一般的であり、図15aに示すように、割りカラーaを構成する半割部材bは、成形加工時に生じた応力に起因して、両側縁部c,cがわずかに近接して開口部が若干狭くなる場合があった。このような状態の半割部材bを被接続管eの接続部に被着しようとすると、該半割部材bの前記側縁部c内周面に塗布した接着剤dが、被接続管eの外周面で掻き取られてしまい、図15bに示すように、側縁部c付近で接着剤dが充分に充填されないという問題があった。 However, the conventional split collar is generally a molded product that is injection-molded with a polyvinyl chloride material. As shown in FIG. 15a, the half member b that constitutes the split collar a is caused by stress generated during the molding process. In some cases, the side edges c, c are slightly close to each other and the opening is slightly narrowed. When the half member b in such a state is to be attached to the connection portion of the connection pipe e, the adhesive d applied to the inner peripheral surface of the side edge portion c of the half member b is applied to the connection pipe e. As shown in FIG. 15 b, there is a problem that the adhesive d is not sufficiently filled in the vicinity of the side edge portion c.
そこで、本発明は、上記課題を解決することができる管補修用連結部材を提供することを目的とする。 Then, an object of this invention is to provide the connection member for pipe repair which can solve the said subject.
本発明は、上記課題を解決するためになされたものであり、接続されるべき被接続管同士の接続部の外形に対応する内面形状を有する一対の半円筒形の半割部材からなり、該半割部材の内周面にそれぞれ接着剤を塗布し、該一対の半割部材を前記接続部に該一対の半割部材の両側縁部同士を突き合わせて挟着することにより、該被接続管同士を接続固定する管補修用連結部材であって、前記半割部材の側縁部内周面に接着剤溜り部を凹設し、該一対の半割部材を前記接続部に挟着した状態で該接着剤溜り部に接着剤が残留するようにしたことを特徴とする管補修用連結部材である。 The present invention has been made in order to solve the above problems, and comprises a pair of semi-cylindrical half members having an inner surface shape corresponding to the outer shape of the connecting portion between the connected pipes to be connected, Applying an adhesive to the inner peripheral surface of each half member, and sandwiching the pair of half members into the connecting portion with both side edges of the pair of half members butted together, A pipe repair connecting member for connecting and fixing each other, wherein an adhesive reservoir portion is recessed on the inner peripheral surface of the side edge portion of the half member, and the pair of half members are sandwiched between the connection portions. A pipe repair connecting member characterized in that an adhesive remains in the adhesive reservoir.
上記のように接着剤溜り部を設けると、該一対の半割部材を前記接続部に挟着した状態で該側縁部付近に接着剤を充分に充填することが可能となるため、該一対の半割部材を確実に被接続管同士の接続部に取り付けることができる。 When the adhesive reservoir is provided as described above, the adhesive can be sufficiently filled in the vicinity of the side edge portion with the pair of halved members sandwiched between the connection portions. The half member can be securely attached to the connecting portion between the pipes to be connected.
また、前記接着剤溜り部は、前記側縁部の肉厚を薄くするように傾斜した傾斜部によって構成されているものが望ましい。 Further, the adhesive reservoir portion is preferably constituted by an inclined portion inclined so as to reduce the thickness of the side edge portion.
かかる構成とすることにより、前記側縁部の周壁の肉厚をある程度確保しつつ、該周壁に応力集中を生じさせることなく接着剤溜り部を設けることができるため、強度の点で有利である。 By adopting such a configuration, it is advantageous in terms of strength because an adhesive reservoir can be provided without causing stress concentration on the peripheral wall while securing a certain thickness of the peripheral wall of the side edge portion. .
ところで、上述のように半割部材の側縁部付近に充分な接着剤が残留するようになると、該接着剤に起因して、該半割部材が該被接続管に対して滑りやすくなり、取付作業時に位置ズレが生じやすくなる可能性がある。このため、以下の構成が提案される。
すなわち、被接続管の接続部に挟着した前記一対の半割部材を係合状態とする位置ズレ防止手段を、該半割部材の両側縁部付近の外周面にそれぞれ配設した構成である。
By the way, as described above, when sufficient adhesive remains in the vicinity of the side edge of the half member, the half member becomes slippery with respect to the connected pipe due to the adhesive. There is a possibility that misalignment is likely to occur during installation work. For this reason, the following configuration is proposed.
That is, it is a configuration in which the positional deviation preventing means for engaging the pair of half members clamped to the connecting portion of the pipe to be connected is disposed on the outer peripheral surface near both side edges of the half member. .
かかる構成とすることにより、一対の半割部材が被接続管に挟着した際に係合状態となるため、互いに位置ズレが生じない。 By adopting such a configuration, the pair of halved members are brought into an engaged state when sandwiched between the pipes to be connected, so that no positional deviation occurs.
さらに、前記位置ズレ防止手段は、互いに係合する雄型位置ズレ防止手段と雌型位置ズレ防止手段とからなり、雄型位置ズレ防止手段及び雌型位置ズレ防止手段からなる組を、前記半割部材の軸線を基準にしてそれぞれ両側に配置し、かつ、一側に配された組の雄型位置ズレ防止手段と他側に配された組の雄型位置ズレ防止手段とを、また一側に配された組の雌型位置ズレ防止手段と他側に配された組の雌型位置ズレ防止手段とを、該軸線上に設定される基準点を中心にして、それぞれ点対称となるように配置し、さらに該一対の半割部材を同一寸法形状とし、該一対の半割部材を前記接続部に挟着した状態で、一方の半割部材に配された雄型位置ズレ防止係合手段および雌型位置ズレ防止手段と、他方の半割部材に配された雌型位置ズレ防止手段および雄型位置ズレ防止手段とが係合する構成が提案される。 Further, the position misalignment prevention means includes a male position misalignment prevention means and a female type position misalignment prevention means that are engaged with each other. A set of male position deviation prevention means arranged on one side and the set arranged on one side and the set of male position deviation prevention means arranged on the other side are arranged on both sides with respect to the axis of the split member. The set of female position deviation prevention means arranged on the side and the set of female type position deviation prevention means arranged on the other side are respectively symmetrical with respect to a reference point set on the axis. Further, the pair of halved members have the same size and shape, and the pair of halved members are sandwiched between the connecting portions, and the male position shift prevention member disposed on one of the halved members is arranged. Alignment means and female mold position deviation prevention means, and female mold position deviation prevention arranged on the other half member And means and male displacement prevention means configured to engage is proposed.
かかる構成にあっては、各半割部材の左右の向きに関わらず、該一対の半割部材の両側縁部同士を突き合わせると常に一方の半割部材の各位置ズレ防止手段と他方の半割部材の各位置ズレ防止手段とが適正に係合するため、補修作業における作業性が極めて良い。 In such a configuration, regardless of the left and right orientations of each half member, when both side edges of the pair of half members are brought into contact with each other, each positional deviation prevention means of one half member and the other half are prevented. Since each position deviation prevention means of a split member engages appropriately, workability | operativity in repair work is very good.
また、前記位置ズレ防止手段は、凸形状をなし、前記半割部材の両側縁部付近の外周面から突き合わせ方向に向けてそれぞれ突出させ、かつ、該半割部材の軸線を基準にして一側に配された位置ズレ防止手段と他側に配された位置ズレ防止手段とを、該軸線上に設定される基準点を中心にして、点対称となるように配置し、さらに該一対の半割部材を同一寸法形状とし、該一対の半割部材を前記接続部に挟着した状態で、一方の半割部材に配された位置ズレ防止手段と他方の半割部材に配された位置ズレ防止手段とが並接し、該一対の半割部材が係合するようにした構成としてもよい。 Further, the positional deviation prevention means has a convex shape, protrudes from the outer peripheral surface in the vicinity of both side edges of the half member toward the abutting direction, and one side with respect to the axis of the half member The positional deviation prevention means arranged on the other side and the positional deviation prevention means arranged on the other side are arranged so as to be symmetric with respect to a reference point set on the axis, and further With the split member having the same size and shape and the pair of half members sandwiched between the connecting portions, the misalignment preventing means disposed on one half member and the misalignment disposed on the other half member. It is good also as a structure which the prevention means adjoins and this pair of half member engages.
かかる構成としても、各半割部材の左右の向きに関わらず、該一対の半割部材の両側縁部同士を突き合わせれば、該一対の半割部材が噛み合って係合するため、補修作業における作業性が極めて良い。加えて、本構成は半割部材の形状を単純化できる利点がある。 Even in such a configuration, regardless of the left and right orientations of each half member, if both side edges of the pair of half members are brought into contact with each other, the pair of half members are engaged and engaged. Workability is very good. In addition, this configuration has an advantage that the shape of the half member can be simplified.
また、前記位置ズレ防止手段の表面に、前記半割部材の周囲に巻回される番線をガイドする番線ガイド溝を凹設してもよい。 In addition, a number guide groove that guides a number wound around the halved member may be provided on the surface of the displacement prevention means.
かかる構成とすると、半割部材の本体に別途番線をガイドするためのガイド手段を設ける必要がない。 With such a configuration, it is not necessary to separately provide a guide means for guiding the number wire in the main body of the half member.
本発明の管補修用連結部材は、被接続管同士の接続部に取り付けた際に充分な量の接着剤が充填されるため、被接続管を確実に接続固定できる効果がある。 The connecting member for repairing a pipe according to the present invention is filled with a sufficient amount of adhesive when attached to the connecting portion between the connected pipes, so that the connected pipe can be reliably connected and fixed.

Each half member 2A (2B) has side edge portions 3 and 3 in the axial direction that face each other, and the pair of half members 2A and 2B are formed on the outer peripheral surface in the vicinity of the side edge portion 3. Position misalignment prevention means 10A, 10B, 11A, and 11B are provided for bringing the two into an engaged state.
More specifically, the positional deviation prevention means 10A, 10B, 11A, and 11B are composed of a male type positional deviation prevention means 10A (10B) and a female type positional deviation prevention means 11A (11B). The misalignment prevention means 10A (10B) is composed of a block body in which a number guide groove 13 for guiding a number 8 described later is recessed on the surface. Further, the female position deviation preventing means 11A (11B) includes two convex members 14 and 14 arranged in the direction of the axis L1. Further, the interval between the convex members 14 is the same as the horizontal width of the block body related to the male-type misalignment preventing means 10A (10B), and between the convex members 14 of the female-type misalignment preventing means 11A (11B). The male position deviation prevention means 10A (10B) is inserted from the upper side or the lower side so as to be fitted and engageable.
さらに、半割部材2A(2B)の軸線L1を基準にして、雄型位置ズレ防止手段10A(10B)及び雌型位置ズレ防止手段11A(11B)からなる組が、それぞれ両側に配置されている。そして、一側に配された雄型位置ズレ防止手段10A(10B)と他側に配された雄型位置ズレ防止手段10A(10B)は、該軸線L1上に設定される仮想の基準点を中心にして、点対称となるように配置されている。同様に、一側に配された雌型位置ズレ防止手段11A(11B)と他側に配された雌型位置ズレ防止手段11A(11B)も、該基準点を中心にして、点対称となるように配置されている。 Further, a set of male type misalignment prevention means 10A (10B) and female type misalignment prevention means 11A (11B) is arranged on both sides with reference to the axis L1 of the half member 2A (2B). . Then, the male position deviation preventing means 10A (10B) arranged on one side and the male position deviation preventing means 10A (10B) arranged on the other side have virtual reference points set on the axis L1. It is arranged so as to be point-symmetric with respect to the center. Similarly, the female position deviation preventing means 11A (11B) arranged on one side and the female type position deviation preventing means 11A (11B) arranged on the other side are also point-symmetric with respect to the reference point. Are arranged as follows.
また、図1,3に示すように、前記半割部材2A(2B)の内周面全体は、接着剤30が塗布される接着部5Aとされ、さらに該接着部5Aにおける前記側縁部3の位置には、接着剤溜り部5Bが凹設されている。該接着剤溜り部5Bは、他の部分よりも厚く接着剤30が塗布される(図6参照)。 As shown in FIGS. 1 and 3, the entire inner peripheral surface of the half member 2A (2B) is an adhesive portion 5A to which an adhesive 30 is applied, and the side edge portion 3 in the adhesive portion 5A. The adhesive reservoir portion 5B is recessed at the position. The adhesive reservoir portion 5B is applied with the adhesive 30 thicker than other portions (see FIG. 6).
本実施例の接着剤溜り部5Bは、前記側縁部3の肉厚を薄くするように傾斜した傾斜部によって構成されており、図3に示すように、該傾斜部の傾斜面は、前記側縁部3の端縁から10mm(=d2)だけ内側に位置したところに設定された仮想鉛直基準線kに対してα=15°の角度で傾斜するように設定されている。なお、接着剤溜り部5Bは、側縁部3に沿って帯状に形成されているが、該側縁部3に沿って非連続に形成されていてもよい。 The adhesive reservoir portion 5B of the present embodiment is configured by an inclined portion that is inclined so as to reduce the thickness of the side edge portion 3, and as shown in FIG. It is set so as to be inclined at an angle of α = 15 ° with respect to a virtual vertical reference line k set at a position 10 mm (= d2) inward from the edge of the side edge portion 3. The adhesive reservoir 5 </ b> B is formed in a strip shape along the side edge 3, but may be formed discontinuously along the side edge 3.
上記構成の割りカラー1Aは、例えば図4に示す施工手順で接続されるべき被接続管20,20同士の接続部21に取り付けられ、図5に示すような被接続管20,20同士を接続固定した状態で補修完了となる。
以下、順に施工手順を説明するが、半割部材2A,2Bに設けられている上記位置ズレ防止手段10A,10B,11A,11Bは、図4では図示省略している。
The split collar 1A having the above-described configuration is attached to, for example, the connecting portion 21 between the pipes 20 and 20 to be connected in the construction procedure shown in FIG. 4, and connects the pipes 20 and 20 as shown in FIG. Repair is completed in a fixed state.
Hereinafter, although the construction procedure will be described in order, the above-described misalignment prevention means 10A, 10B, 11A, and 11B provided in the half members 2A and 2B are not shown in FIG.
まず、破損部位を含む配水管部分を管軸に対して直角に切断して除去し(図4a)、さらに、継ぎ手部材19を接続し(図4b)、該継ぎ手部材19と被接続管20との間の間隙Sに新たに短管28Aを介挿する。 First, the water distribution pipe portion including the damaged portion is cut and removed at right angles to the pipe axis (FIG. 4a), and the joint member 19 is connected (FIG. 4b). The joint member 19 and the connected pipe 20 are connected to each other. A short tube 28A is newly inserted in the gap S between the two.
次に、前記短管28Aと被接続管20との間隙Sにさらに別途短管28Bを介挿し、前記短管28A,28Bを、割りカラー1Aの取り付け対象としての被接続管20とする。これと共に、半割部材2A,2Bの内周面全体に接着剤30を塗布し、これら接続されるべき被接続管20同士の接続部21を被覆するように前記一対の半割部材2A,2Bを挟着する(図4c)。このとき、上側の半割部材2Aの雄型位置ズレ防止手段10Aが、下側の半割部材2Bの雌型位置ズレ防止手段11Bに介挿されて両位置ズレ防止手段10A,11Bが係合すると共に、上側の半割部材2Aの雌型位置ズレ防止手段11Aに、下側の半割部材2Bの雄型位置ズレ防止手段10Bが介挿されて両位置ズレ防止手段11A,10Bが係合する。そして、両半割部材2A,2Bが互いに軸線方向で位置ズレすることなく係合状態となる。
なお、継ぎ手部材19の寸法、短管28A,28Bの寸法等は、適宜公知技術に基づき補修作業者により設定される。
Next, a short pipe 28B is further inserted in the gap S between the short pipe 28A and the connected pipe 20, and the short pipes 28A and 28B are used as the connected pipe 20 to be attached with the split collar 1A. At the same time, the adhesive 30 is applied to the entire inner peripheral surfaces of the half members 2A, 2B, and the pair of half members 2A, 2B are covered so as to cover the connecting portions 21 between the pipes 20 to be connected. Is sandwiched (FIG. 4c). At this time, the male position deviation prevention means 10A of the upper half member 2A is inserted into the female position deviation prevention means 11B of the lower half member 2B, and the both position deviation prevention means 10A, 11B are engaged. At the same time, the male position deviation preventing means 10B of the lower half member 2B is inserted into the female position deviation preventing means 11A of the upper half member 2A so that both position deviation preventing means 11A and 10B are engaged. To do. And both the half members 2A and 2B will be in an engagement state, without mutually shifting in an axial direction.
The dimensions of the joint member 19, the dimensions of the short pipes 28A and 28B, and the like are appropriately set by a repair worker based on known techniques.
そして、前記半割部材2A,2Bの外周に、番線(焼きなまし番線)8を雄型位置ズレ防止手段10A,10Bに設けられた番線ガイド溝13に沿って巻き付け、該割りカラー1Aを被接続管20に確実に接続する。これにより、被接続管20同士が接続固定され、配水管の補修が完了する(図5参照)。 A wire (annealing wire) 8 is wound around the outer periphery of the half member 2A, 2B along the wire guide groove 13 provided in the male position shift preventing means 10A, 10B, and the split collar 1A is connected to the pipe to be connected. Connect to 20 securely. Thereby, the to-be-connected pipes 20 are connected and fixed, and the repair of the water distribution pipe is completed (see FIG. 5).
ここで、図6aに示すように、前記接着剤溜り部5Bには、他の部位よりも接着剤30を厚く塗布することができ、また該接着剤溜り部5Bを設けたことにより該半割部材2A(2B)における開口部が若干拡開されるため、図6bに示すように該一対の半割部材2A,2Bを被接続管20に被着した際に、側縁部3付近の接着剤30が被接続管20に掻き取られることがない。かくして、該接着剤溜り部5Bに充分な接着剤30が残留した状態で該一対の半割部材2A,2Bが被接続管20に被着するから、該割りカラー1Aは確実に被接続管20に被着され、該被接続管20同士が確実に接続固定される。 Here, as shown in FIG. 6a, the adhesive reservoir 5B can be coated with the adhesive 30 thicker than other parts, and the adhesive reservoir 5B is provided to provide the half of the adhesive. Since the opening in the member 2A (2B) is slightly expanded, when the pair of halved members 2A and 2B are attached to the connection pipe 20 as shown in FIG. The agent 30 is not scraped off by the connected pipe 20. Thus, since the pair of halved members 2A and 2B adheres to the connected pipe 20 with sufficient adhesive 30 remaining in the adhesive reservoir 5B, the split collar 1A is surely connected to the connected pipe 20. The connecting pipes 20 are securely connected and fixed to each other.
また、本発明の割りカラー1Aにあっては、図5に示すように、雄型位置ズレ防止手段10A(10B)が、雌型位置ズレ防止手段11A(11B)に適嵌して係合するため、番線8を締め付ける際に、半割部材2Aと半割部材2Bとが軸線L1方向で位置ズレしない。したがって、番線8の締め付け作業が極めて容易となる。 Further, in the split collar 1A of the present invention, as shown in FIG. 5, the male position deviation preventing means 10A (10B) is fitted and engaged with the female type position deviation preventing means 11A (11B). For this reason, when the wire 8 is tightened, the half member 2A and the half member 2B are not displaced in the direction of the axis L1. Therefore, the tightening operation of the wire 8 becomes extremely easy.
また、本発明の割りカラー1Aは、前記半割部材2A,2Bを合わせる際に、各半割部材2A,2Bの左右の向きを考慮する必要がない。すなわち、該一対の半割部材2A,2Bは同一寸法形状であり、各位置ズレ防止手段10A,10B,11A,11Bは、上述のように互いに点対称となるように配設されているため、一方の半割部材2A(2B)に対して、他方の半割部材2B(2A)を側縁部3同士を突き合わせるようにして合わせれば、常に上側の半割部材2Aの位置ズレ防止手段10A,11Aと、下側の半割部材2Bの位置ズレ防止手段10B,11Bとが適嵌し係合する。このため、補修作業者は半割部材2A(2B)の左右の向きをいちいち確認することなく補修作業を行えるから、本発明の割りカラー1Aは作業性が極めて良い。 Further, in the split collar 1A of the present invention, when the half members 2A and 2B are combined, it is not necessary to consider the left and right directions of the half members 2A and 2B. That is, the pair of halved members 2A and 2B have the same size and shape, and the positional deviation preventing means 10A, 10B, 11A and 11B are arranged so as to be point-symmetric with each other as described above. If the other half member 2B (2A) is aligned with the other half member 2A (2B) so that the side edge portions 3 face each other, the positional deviation preventing means 10A of the upper half member 2A is always maintained. 11A and the misalignment preventing means 10B, 11B of the lower half member 2B are fitted and engaged appropriately. For this reason, the repair worker can perform the repair work without checking the left and right directions of the half member 2A (2B) one by one. Therefore, the split collar 1A of the present invention has very good workability.
また、前記雄型位置ズレ防止手段10A(10B)に番線ガイド溝13が設けられているため、半割部材2A(2B)の本体に別途番線8をガイドするためのガイド手段を設ける必要がない。 Further, since the number-line guide groove 13 is provided in the male position deviation prevention means 10A (10B), it is not necessary to provide a guide means for separately guiding the number line 8 in the main body of the half member 2A (2B). .
前記接着剤溜り部5Bは、別の形態としてもよい。
例えば、図7に示すように、半割部材2A(2B)の周壁の肉厚を薄くする凹状段部を接着剤溜り部5Cとしてもよい。なお、接着剤溜り部5B,5Cは、図3に示す接着剤溜り部5Bの方が、半割部材2A(2B)の肉厚をある程度確保できるし、かつ当該接着剤溜り部5B周りに応力集中が生じにくいため、強度の点で望ましい。
The adhesive reservoir 5B may have another form.
For example, as shown in FIG. 7, a concave stepped portion that reduces the thickness of the peripheral wall of the half member 2A (2B) may be used as the adhesive reservoir 5C. Note that the adhesive reservoir 5B, 5C can secure a certain thickness of the halved member 2A (2B) to the extent that the adhesive reservoir 5B shown in FIG. 3 has a stress around the adhesive reservoir 5B. Since concentration is difficult to occur, it is desirable in terms of strength.
〈第二実施例〉
第二実施例は、図8に示すように、割りカラー1Bを二つ使用するものであり、一方の割りカラー1Bは一対の半割部材2C,2Cで構成され、他方の割りカラー1Bは一対の半割部材2D,2Dで構成されている。
<Second Example>
As shown in FIG. 8, the second embodiment uses two split collars 1B. One split collar 1B is composed of a pair of half members 2C and 2C, and the other split collar 1B is a pair. Halved members 2D and 2D.
該半割部材2C(2D)において、一側の側縁部3外周面に一つの雄型位置ズレ防止手段21C(21D)が配設され、他側の側縁部3外周面に一つの雌型位置ズレ防止係合手段22C(22D)が配設されている。該雄型位置ズレ防止手段21C(21D)及び雌型位置ズレ防止手段22C(22D)は、第一実施例の雄型位置ズレ防止手段10A(10B)及び雌型位置ズレ防止手段11A(11B)とそれぞれ同形態である。なお、第二実施例の半割部材2C(2D)には切断溝6は形成されていない。 In the half member 2C (2D), one male-type displacement prevention means 21C (21D) is disposed on the outer peripheral surface of the side edge 3 on one side, and one female is disposed on the outer peripheral surface of the side edge 3 on the other side. Mold position deviation preventing engagement means 22C (22D) is provided. The male position deviation preventing means 21C (21D) and female position deviation preventing means 22C (22D) are the male position deviation preventing means 10A (10B) and the female position deviation preventing means 11A (11B) of the first embodiment. And the same form. Note that the cutting groove 6 is not formed in the half member 2C (2D) of the second embodiment.
また、各半割部材2C(2D)は、第一実施例と同様に、内周面全体を接着部5Aとし、該接着部5Aの前記側縁部3に接着剤溜り部5Bが凹設されている。 Further, each half member 2C (2D) has an inner peripheral surface as an adhesive portion 5A, and an adhesive reservoir portion 5B is recessed in the side edge portion 3 of the adhesive portion 5A, as in the first embodiment. ing.
上記構成の割りカラー1Bは、例えば図9に示す施工手順で被接続管20に取り付けられて、図10に示すような補修完了状態となる。なお、前記半割部材2C,2Dに設けられている位置ズレ防止手段21C,21D,22C,22Dは、図9では図示省略している。
まず、破損部位を含む配水管部分を管軸に対して直角に切断して除去し(図9a)、これにより生じた間隙Sに新たに短管28Cを介挿して、該短管28Cを被接続管20とする(図9b)。次に、各半割部材2C,2Dの内周面全体にそれぞれ接着剤30を塗布し、該一対の半割部材2C,2Dからなる割りカラー1B,1Bを、各接続部21,21を被覆するように各々挟着する(図9c)。このとき、各位置ズレ防止手段21C,21D,22C,22Dが互いに係合する。さらに、雄型位置ズレ防止手段21C(21D)に設けられた番線ガイド溝13に沿って番線(焼きなまし番線)8を巻き、該割りカラー1Bを被接続管20に確実に取り付ける(図9d)。これにより、配水管の補修が完了する(図10参照)。かかる構成においても、接着剤溜り部5Bに充分な接着剤30が残留するから、該割りカラー1Bは確実に被接続管20に被着され、該被接続管20同士が確実に接続固定される。
The split collar 1B having the above-described configuration is attached to the connected pipe 20 by, for example, the construction procedure shown in FIG. 9 and is in a repair completed state as shown in FIG. The misalignment prevention means 21C, 21D, 22C, and 22D provided in the half members 2C and 2D are not shown in FIG.
First, the water distribution pipe portion including the damaged part is removed by cutting at right angles to the pipe axis (FIG. 9a), and the short pipe 28C is newly inserted into the gap S generated thereby, so that the short pipe 28C is covered. The connecting pipe 20 is assumed (FIG. 9b). Next, the adhesive 30 is applied to the entire inner peripheral surface of each half member 2C, 2D, and the split collars 1B, 1B comprising the pair of half members 2C, 2D are covered with the connection portions 21, 21. Each of them is sandwiched as shown in FIG. 9c. At this time, the respective displacement prevention means 21C, 21D, 22C, 22D are engaged with each other. Further, a number line (annealed number line) 8 is wound along the number line guide groove 13 provided in the male position deviation preventing means 21C (21D), and the split collar 1B is securely attached to the connected pipe 20 (FIG. 9d). Thereby, repair of a water pipe is completed (refer FIG. 10). Even in such a configuration, since sufficient adhesive 30 remains in the adhesive reservoir 5B, the split collar 1B is reliably attached to the connected pipe 20, and the connected pipes 20 are securely connected and fixed. .
ここで、上記位置ズレ防止手段21C,21D,22C,22Dは、他の形態としてもよい。
例えば図11a〜図11cに示すように、位置ズレ防止手段23C(23D)を凸部材で構成し、前記側縁部3付近の外周面から突き合わせ方向に向けてそれぞれ突出させた構成が提案される。
Here, the misalignment prevention means 21C, 21D, 22C, 22D may have other forms.
For example, as shown in FIGS. 11 a to 11 c, a configuration is proposed in which the misalignment prevention means 23 </ b> C (23 </ b> D) is configured by a convex member and protrudes from the outer peripheral surface in the vicinity of the side edge 3 toward the butting direction. .
さらに詳述すると、位置ズレ防止手段23C(23D)が半割部材2C(2D)の軸線L2を基準にして両側に配置され、さらに軸線L2を基準にして一側に配された位置ズレ防止手段23C(23D)と他側に配された位置ズレ防止手段23C(23D)とが、該軸線L2上に設定される基準点を中心にして、点対称となるように配置される。また、該一対の半割部材2C,2Dは同一寸法形状の成形体とされる。
かかる構成にあって、図12a〜図12cに示すように、該一対の半割部材2C,2Dが被接続管20に挟着された状態では、一方の半割部材2Cに配された位置ズレ防止手段23Cと他方の半割部材2Dに配された位置ズレ防止手段23Dとがそれぞれ並接し、これにより該一対の半割部材2C,2Dが噛み合った状態となる。かくして、該一対の半割部材2C,2Dは軸線L2方向への移動が制限されて係合状態となる。
More specifically, the positional deviation prevention means 23C (23D) is arranged on both sides with respect to the axis L2 of the half member 2C (2D), and is further arranged on one side with respect to the axis L2. 23C (23D) and the misalignment prevention means 23C (23D) arranged on the other side are arranged so as to be symmetric with respect to a reference point set on the axis L2. The pair of halved members 2C and 2D are formed into the same size and shape.
In such a configuration, as shown in FIGS. 12a to 12c, in the state where the pair of half members 2C and 2D are sandwiched between the pipes 20 to be connected, the positional deviation disposed on one half member 2C is shifted. The prevention means 23C and the positional deviation prevention means 23D disposed on the other half member 2D are in parallel with each other, whereby the pair of half members 2C and 2D are engaged. Thus, the pair of half members 2C, 2D are restricted from moving in the direction of the axis L2 and become engaged.
また、図13a〜図13cに示すように、前記凸部材の外形を変更した位置ズレ防止手段24C,24Dとしてもよい。かかる位置ズレ防止手段24C,24Dは、図11,図12に示す構成と同様の配置とされ、さらに図14a〜図14cに示すように、該一対の半割部材2C,2Dを合わせた際に、一方の半割部材2Cの各位置ズレ防止手段24Cの凹部と、他方の半割部材2Dの位置ズレ防止手段24Dの凹部とでガイド溝13が形成されるようにした構成である。かかる構成とすることにより適正に番線8をガイドすることが可能となる。 Further, as shown in FIGS. 13a to 13c, misalignment prevention means 24C and 24D in which the outer shape of the convex member is changed may be used. The misalignment prevention means 24C and 24D are arranged in the same manner as the configuration shown in FIGS. 11 and 12, and when the pair of half members 2C and 2D are combined, as shown in FIGS. 14a to 14c. The guide groove 13 is formed by the recesses of the respective misalignment prevention means 24C of one half member 2C and the recesses of the misalignment prevention means 24D of the other half member 2D. With this configuration, it is possible to properly guide the wire 8.
上記構成にあって、接着剤30としては、PVC系接着剤、エポキシ系接着剤(いわゆる接合剤)でもよいし、他の分類の接着剤でもよい。 In the above configuration, the adhesive 30 may be a PVC adhesive, an epoxy adhesive (so-called bonding agent), or another type of adhesive.
