Description
【０００１】[0001]
本考案は地下に敷設される情報・通信ケーブルのハンドホールや、その他の下 水道等におけるマンホールと台付管の接続部分に用いられるところの耐震性継手 と台付管の接続用継ぎ部材に関する。 The present invention relates to a joint member for connecting a seismic joint and a base pipe to be used for a handhole of an information / communication cable laid underground or a connection part of a manhole and a base pipe in other sewers.
【０００２】[0002]
例えば、光ファイバーなどの情報・通信ケーブルを地下に敷設しようとした場 合、ケーブルの配線、点検・補修用のハンドホールを適宜距離毎に据え付けて、 このハンドホール間に多数の管を直列に接続して継ぎ、管内に情報・通信ケーブ ルを通している。 そして、ハンドホールと管の接続部分では、両者間における耐震、密閉状態を 確保するため、柔軟・弾性部材からなる耐震性継手たとえば筒状のブーツ（商品 名）を介在させて施工している。具体的には、ハンドホール側面の孔にブーツの 一方を挿入して内部バンドで固定し、ブーツの他方に管を挿入して締結バンドに より固定して接続している。 ところで、管には、径断面が円筒状であるものと、底面側に平坦なフラットベ ースを形成してあるところの所謂台付管と呼ばれているものがあり、施工性、コ ストの面から、後者の台付管が、台付形状で安定性が良く、基礎上に並べて差し 込み継ぐだけで据え付け・接合できて工事作業が簡単である。 したがって、施工性が優れている台付管を採用したいところであるが、台付管 は輪郭形状が直線部を有する異形状になっているため、ブーツとの接合部分が甘 くなりがちであり、密閉能力に不安が残る接続構造である。 For example, if information and communication cables such as optical fibers are to be laid underground, handholes for cable wiring, inspection and repair should be installed at appropriate distances, and a number of pipes should be connected in series between these handholes. And pass through the information and communication cable in the jurisdiction. At the joint between the handhole and the pipe, the seismic joint made of flexible and elastic members, such as a tubular boot (trade name), is interposed to ensure seismic resistance and sealing between the two. Specifically, one of the boots is inserted into the hole on the side of the handhole and fixed with an internal band, and a tube is inserted into the other of the boot and fixed and connected with a fastening band. By the way, there are two types of pipes, one with a cylindrical cross section and the other with a flat base formed on the bottom side, which is called a so-called base pipe. From the point of view, the latter mounting pipe has good mounting stability and can be installed and joined simply by laying it on the foundation and connecting it, making construction work easy. Therefore, it is desirable to use a base tube with excellent workability.However, since the base tube has a different shape with a straight portion, the joint with the boot tends to be loose. This connection structure leaves concerns about the sealing ability.

解決しようとする課題は、第１には、耐震性継手と台付管を密閉状態に簡単且 つ確実に接続することが可能である接続用継ぎ部材を、第２には、さらに、台付 管の挿入取付けが容易で且つ密閉具合が強固である接続用継ぎ部材を提供するこ とにある。 The problem to be solved is, firstly, a connecting joint member capable of easily and reliably connecting the earthquake-resistant joint and the base pipe in a sealed state, and secondly, a base mounting pipe. It is an object of the present invention to provide a connecting joint member in which a tube can be easily inserted and mounted and a sealing condition is strong.
