(57) [Summary] (Modified) [PROBLEMS] To provide a joint of a concrete segment having an integral structure. SOLUTION: An anchor bar 3 buried in concrete is protruded from a metal body, and the metal body 2 and the anchor bar are integrally formed. [Effect] The joint fitting body and anchor part are 1
Since they are integrally formed in the process, there is no need to assemble fittings, there is little rust, and there is no fear of breakage of the welded portion as in the prior art.
Description
【０００１】[0001]
トンネル覆工用等コンクリートセグメントの継手金具に関するものである。 The present invention relates to a fitting for a concrete segment for tunnel lining.
【０００２】[0002]
従来一般に使用されているコンクリートセグメントの継手金具は金物本体から 突設し、コンクリート中に埋設するアンカー筋が設けてある。そして金物本体と アンカー筋とは溶接されているか、あるいは金物本体の雌螺子孔にアンカー筋基 部の螺子部分を螺合して構成している。 Conventionally used joint fittings for concrete segments are There is an anchor bar that projects and is embedded in concrete. And with the hardware body The anchor bar is welded, or the anchor bar is attached to the female screw hole of the hardware body. The screw part of the section is screwed together.
【０００３】[0003]
ところで近年各種現場溶接の信頼性が問題視されつつある。 By the way, in recent years, the reliability of various on-site welding is becoming a problem.
【０００４】 そこでこの考案は溶接箇所のない継手金具全体を一体成形の構造とした。[0004] Therefore, in this invention, the entire joint fitting having no welding points is integrally formed.
【０００５】[0005]
この考案は金物本体とアンカー筋を鋳造によって一体成形してある。 In this invention, the metal body and the anchor bar are integrally formed by casting.
【０００６】[0006]
コンクリートセグメントＡ，Ａの接合端面には継手金具１，１がそれぞれ固定 されている。この継手金具は本体２部と複数本突設されたアンカー３部の鋳造に よる一体成形されており、溶接接着、仕口等による接合構造でない。 Joint fittings 1 and 1 are fixed to the joint end faces of concrete segments A and A, respectively. Has been done. This fitting is suitable for casting 2 parts of the main body and 3 parts of the protruding anchors. It is integrally formed by welding, and it is not a joint structure such as welding adhesion or joint.
【０００７】 アンカー３はコンクリートセグメントＡのコンクリート中に埋設され、本体２ は隣接するコンクリートセグメントと突合せ、ボルトナット４によって接合され て使用される。またアンカー３は必要により鍔上等の突起５が形成してあり、複 数本突設された形状である。[0007] The anchor 3 is embedded in the concrete of the concrete segment A, and the main body 2 Butt adjacent concrete segments and are joined by bolts and nuts 4 Used. In addition, the anchor 3 is formed with a protrusion 5 such as a collar as required, It has a shape in which several pieces are projected.
【０００８】[0008]
この考案は以上の構成からなり、継手金具本体とアンカー部は鋳造等によって １工程で一体成形されているので、継手金具の組立手間がなく、錆の発生も少な く、従来のような熔接部の破断の心配がない。 This invention has the above-mentioned configuration, and the joint metal fitting body and the anchor portion are made by casting or the like. Since it is integrally molded in one process, there is no need to assemble joint fittings, and there is little rust. In addition, there is no concern about breakage of the welded portion as in the past.
