【従来の技術】[Prior art]

この種の従来の排気管連結用継ぎ手構造は、例えばイギリス特許出願公告GB 2037922号(出願日1979年11月12日)に記載されているように、 2本の排気管の隣接する各端部の円周上に、その各端部を取り囲み締結できるよ うに1個の円状の、切り目を有する帯金を配設し、排気管の各端部の内部表面の 円周上に接して縮合可能なリングを内接し、中心部に橋台状に1個のクランプを 形成した台座を帯金の切り目の両端部に固定し、その両端部において帯金を収縮 するためのクランプとそれに螺合するボルト・ナットからなるクランプ装置を配 設している。クランプ装置により帯金の両端部を締め付けると、連結される各排 気管の端部の内部表面の円周上に内接したリングと帯金との間において、2本の 排気管の隣接する各端部が締結され排気管が相互に緊結される仕組みになってい る。 A conventional exhaust pipe connecting joint structure of this kind is disclosed, for example, in British Patent Application Publication No. GB 20379922 (filing date: November 12, 1979), in which two adjacent end portions of two exhaust pipes are connected to each other.

【考案が解決しようとする課題】[Problems to be solved by the device]

従来の技術によれば、帯金の両端部に固定した台座に形成された1個のクラン プ装置による帯金の締付け性能を高め、帯金とリングとの間において締結された 2本の排気管の隣接する各端部からの排気洩れを防ぐため、帯金を締め付けなが ら排気管の各端部を十分圧接できるように、帯金を板厚を薄くし柔軟な帯金とし て形成する必要があった。このような排気管連結用継ぎ手構造においては、帯金 の両端部に固定された各台座に形成されるクランプは、帯金の幅の中心部に1個 のみ形成されており、また、上述したように帯金は、板厚を薄くし柔軟な構造に することが要求されるため、帯金を締め付けた時その両端部に固定された台座の ほぼ180度反対側部分において帯金の抗張力が弱まり伸びやゆるみなどの変形 を生じ、連結される排気管の隣接する各端部における排気洩れなどの原因となっ た。連結する排気管の直径が大きくなれば、帯金の幅を広くしなければならず、 このような従来技術の欠点はますます帯金の締結効果を弱め、排気管からの排気 洩れを生じる原因となる。また帯金の板厚を厚くして剛性を上げようとすれば、 帯金の締付け性能が落ちる。 According to the conventional technology, the tightening performance of the strip is improved by the single clamping device formed on the pedestal fixed to both ends of the strip, and the two exhausts connected between the strip and the ring are improved. In order to prevent exhaust leakage from each adjacent end of the pipe, the strip is made thin and flexible so that each end of the exhaust pipe can be pressed sufficiently while tightening the strip. Had to do. In such an exhaust pipe connecting joint structure, only one clamp is formed on each pedestal fixed to both ends of the strip, and only one clamp is formed at the center of the strip width. As described above, since the strip is required to have a thin plate thickness and a flexible structure, when the strip is tightened, the tensile strength of the strip is about 180 degrees opposite to the pedestal fixed at both ends of the strip. Deformation such as weakening and elongation and loosening occurred, causing exhaust leaks at the adjacent ends of the connected exhaust pipes. The larger the diameter of the exhaust pipe to be connected, the wider the band must be made.The disadvantage of such conventional technology is that the fastening effect of the band is further weakened, causing the exhaust leakage from the exhaust pipe. Becomes If the thickness of the strip is increased to increase the rigidity, the tightening performance of the strip will be reduced.

【0004】 この考案は、前記の点にかんがみ、排気管の締結用帯金を、半円状の2個の帯 金として形成し、それら2個の帯金の各両端部、すなわち半円状の2個の帯金が 連結され形成する円状の帯金のほぼ180度の位置にそれぞれ1個のクランプを 取り付け、帯金の締付け力の分布を、帯金の全周、全幅にゆきわたるようにする ことによって、排気管からの排気洩れを防ぐ排気管連結用継ぎ手構造を提供する ことを目的とする。In view of the above points, this invention forms the exhaust pipe fastening band as two semi-circular bands, and the two ends of each of the two bands, that is, the semi-circular band. A clamp is attached to each of the circular strips that are formed by connecting the two strips at a position of approximately 180 degrees so that the tightening force distribution of the strips can be distributed over the entire circumference and width of the strip. The purpose of this is to provide a joint structure for connecting exhaust pipes that prevents exhaust leakage from the exhaust pipes.

【実施例】【Example】

以下添付図面に基づき、この考案の排気管連結用継ぎ手構造を説明する。 An exhaust pipe connecting joint structure of the present invention will be described below with reference to the accompanying drawings.

【0009】 図1および図2において、1、2は連結する2本の排気管、3、4は2個の半 円状に形成された帯金、5、6は各帯金3、4のそれぞれ両端部に固定された台 座、7、8は橋台状に台座5、6に形成したクランプ、9、10はそれぞれクラ ンプ7、8に螺合するボルトおよびナット、11、12は排気管1、2の隣接す る各端部、13は排気管の各端部11、12の内部表面の円周上に接して内設し た縮合可能なリングである。In FIGS. 1 and 2, 1 and 2 are two exhaust pipes to be connected, 3 and 4 are two semicircular metal strips, and 5 and 6 are metal strips 3 and 4, respectively. The pedestals fixed to both ends, 7 and 8 are clamps formed on the pedestals 5 and 6 in the shape of an abutment, 9 and 10 are bolts and nuts screwed into the clamps 7 and 8, and 11 and 12 are exhaust pipes. Adjacent ends 1 and 2 of the exhaust pipe 13 are condensable rings provided in contact with the inner surfaces of the ends 11 and 12 of the exhaust pipe on the circumference thereof.

【0010】 半円状に形成した2個の帯金3、4を連結するクランプ7、8の台座5および 6の隣接する両端部は、半円状の帯金3、4が連結されて形成する円形状の帯金 構造の円周上ほぼ180度の位置にそれぞれ固定されている。The semi-circular metal strips 3 and 4 are connected to both ends of the pedestals 5 and 6 of the clamps 7 and 8 that connect the two semi-circular metal strips 3 and 4 to each other. They are fixed at positions of about 180 degrees on the circumference of the circular band structure.

【0011】 帯金3、4を、それらの両端部に固定された台座5、6に形成されたクランプ 7、8と、ボルト9、ナット10からなるクランプ装置により連結して形成され る円形の帯金構造とリング13との間に、排気管の各端部11、12をサンドイ ッチ状にはさみ、クランプ装置によって帯金3、4の各両端部を縮合するように 締め付ける。A circular shape formed by connecting the straps 3 and 4 with clamps 7 and 8 formed on pedestals 5 and 6 fixed to both ends thereof, and a clamp device including bolts 9 and nuts 10. The ends 11 and 12 of the exhaust pipe are sandwiched between the band structure and the ring 13, and clamped so that both ends of the bands 3 and 4 are condensed by a clamp device.

【0012】 上述したように、帯金3、4を締め付けた時リング13との間において排気管 の各端部11、12を十分圧接できるようにするため、帯金の材質は、板厚を薄 くした柔軟なものが好ましい。[0012] As described above, the material of the strip is made of a material having a plate thickness so that the ends 11 and 12 of the exhaust pipe can be sufficiently pressed against the ring 13 when the strips 3 and 4 are tightened. A thin and flexible material is preferable.

【0013】 また上述のように、帯金を締め付けるクランプ7、8の台座5、6の隣接する 両端部は、帯金3および4によって形成される円形の帯金構造の円周上ほぼ18 0度の位置にそれぞれ固定されている。このため、その締付け効率を高めるため 要求される薄い板厚の柔軟な構造になっている帯金が、1個の円形状の帯金とし て形成された場合その帯金を締め付けると、その両端部に固定された台座のほぼ 180度反対側部分において帯金の抗張力が弱まり伸びやゆるみなどの変形を生 じる原因が除かれている。Further, as described above, the adjoining both ends of the bases 5 and 6 of the clamps 7 and 8 for tightening the strips are approximately 180 on the circumference of the circular strip structure formed by the strips 3 and 4. It is fixed at each degree position. For this reason, when a strip with a thin and flexible structure required to enhance its tightening efficiency is formed as one circular strip, tightening the strip will result in both ends of the strip being tightened. The reason why the tensile strength of the strip is weakened and deformation such as stretching and loosening is eliminated at a portion on the opposite side of the pedestal fixed at about 180 degrees.

【0014】 この実施例においては、帯金3、4は、それぞれ半円状に2個の帯金として形 成されているため、各帯金の剛性が向上し締め付けやすくなる。よって、無理に 強く締め付ける必要がなくボルト9の負荷が減り、ボルトが曲がるというような 変形の原因が除かれているので作業効率が向上する。In this embodiment, since the strips 3 and 4 are each formed as two strips in a semicircular shape, the strips have improved rigidity and are easily tightened. Therefore, it is not necessary to forcibly tighten the bolt 9, the load on the bolt 9 is reduced, and the cause of deformation such as bending of the bolt is eliminated, so that the working efficiency is improved.

【考案の効果】[Effect of device]

以上説明した通り、この考案による排気管連結用継ぎ手構造は、排気管を締結 する帯金を、半円状の2個の帯金として形成したため、帯金の剛性は強化され、 それらの各両端部に固定された台座に形成した2個のクランプにより2本の排気 管の隣接する各端部を締結する場合、帯金の締付け力の分布を、帯金の全周、全 幅にゆきわたるようにすることができるので、帯金の伸びやゆるみなどの変形が 生じにくくなり、またはボルトへの負荷が2分されるためボルトの変形も防ぐ効 果がある。このため、帯金の締付け効率が向上し、連結する排気管の両端部から の排気洩れの原因が除去される。 As described above, in the exhaust pipe connecting joint structure according to the present invention, since the strip for fastening the exhaust pipe is formed as two semicircular strips, the rigidity of the strip is strengthened, and both ends of each strip are strengthened. When two adjacent ends of two exhaust pipes are fastened with two clamps formed on the pedestal fixed to the part, the distribution of the tightening force of the strip is spread over the entire circumference and width of the strip. Therefore, deformation such as stretching or loosening of the band is less likely to occur, or the load on the bolt is divided into two, which also has the effect of preventing deformation of the bolt. Therefore, the tightening efficiency of the strip is improved, and the cause of exhaust leakage from both ends of the exhaust pipe to be connected is eliminated.
