【0015】
そして、上記の連結ピン13は、その雄ねじ部15を、上記ナット8の前半部に螺着して備えられている。
次に雌型継手具4について説明する。
【0016】
20は、挿入穴20aを有する金属製パイプからなるケースで、その軸方向長Lは、上記連結ピン13における主体部14と係止部16の軸方向長の和Lと同一か或いは若干長く設定されている。
【0017】
ケース20の中間部内面21の内径は、上記連結ピン13における主体部14の外径より若干大径に設定されている。ケース20の前部には、上記中間部内面21からラッパ状に拡開するテーパ状の案内面22が形成されている。更にケース20の後部内面には係止溝23が全周に亘って形成され、その前端面は垂直状の係止面23aに形成されている。該係止溝23の軸方向長Lは、上記連結ピン13における係止部16の軸方向長Lと同一か或いは若干長く設定され、更に、その係止溝23の内径は、上記係止部16における係止鍔部16aの使用前の外径と同径に設定されている。
【0018】
24は金属製の連結板で、上記ケース20の後端面に溶接固着されている。
25は拡開用のテーパ栓で、図4(c)に示すように、円柱状の主体部25aと、その前部に一体形成した案内部25bと、後部に一体形成した仮止め部25cとからなる。
【0019】
主体部25aの外径は上記連結ピン13における穴18の内径より若干大径に形成され、その外周面にはローレット溝26が刻設されている。また、その軸方向長Lは、上記係止溝23の軸方向長Lより若干短く設定されている。
【0020】
案内部25bの外周面は先細状のテーパ面に形成されている。
仮止め部25cの外径は、主体部25aの外径より小径に形成され、その外周面にはローレット溝27が刻設されている。
【0021】
そして、上記拡開用のテーパ栓25は、その仮止め部25cを、上記連結板24の中央部に形成した止穴28に圧入して、該テーパ栓25がケース20内に同心的に仮止めされている。尚、仮止め部25cを主体部25aより小径にしたのは、主体部25aの外表面積を仮止め部25cの外表面積より広くして、後述するようにテーパ栓25を連結ピン13の穴18内に圧入した場合に、主体部25aと連結ピン13との摩擦抵抗力が、仮止め部25cと連結板24との摩擦抵抗力よりも大きくなるようにしてある。
【0022】
29は他方のアンカーバーで、異形鉄筋で形成され、その前端が上記連結板24に溶接にて固着されている。該アンカーバー29の後端部に刻設した雄ねじ29aには、角座30を溶接固着したナット31が螺着されている。
【0023】
そして、上記構成からなる雌型継手4は、他方の連結部材2の成形時に、そのケース20の前端開口部が露出するようにして連結部材2内に一体的に埋設されている。
【0024】
尚、両連結部材1、2が例えば環状のセグメントの場合には、上記の雄型継手3を、一方のセグメント1の接合側面に複数個設け、上記の雌型継手4を、他方のセグメント2の接合側面に、上記複数の雄型継手3に対向して複数個設ける。
【0025】
次に連結作用について説明する。
連結現場にて連結ピン13をナット8に螺着して備える。その連結ピン13がケース20に対向するように、一方の連結部材1を他方の連結部材2に対面させる。そして、一方の連結部材1を他方の連結部材2へ移動して、連結ピン13をケース20内へ押し嵌入する。
【0026】
この嵌入時において、連結ピン13は、そのテーパ部16bと案内面22との係合により、挿入穴20a内に誘導される。このとき、連結ピン13とケース20とが若干偏心している場合には、ナット8の外周部に弾性材料からなる調整部材9が存在し、かつ空隙保持用パイプ10によりアンカーバー5の外周部に空隙12が存在していることにより、連結ピン13が、その直径方向、すなわちケース20の軸心側へ移動し、上記のような偏心状態でもその連結ピン13とケース20の軸心が合致し、連結ピン13がケース20内に確実に嵌入する。
【0027】
一方の連結部材1を更に移動すると、割溝19により連結ピン13が縮径して挿入穴20a内を摺動して進入する。連結ピン13が更に進入すると、その穴18内にテーパ栓25が嵌入し、連結ピン13が拡径して、その係止鍔部16aが係止溝23内に嵌入し、その係止面16cが係止溝23の係止面23aに対面して相互に係止する。この係合状態において、両連結部材1、2が相互に最接近した接合状態となる。
【0028】
上記のように係止することにより、連結ピン13の抜け外れが阻止され、両連結部材1、2は相互に連結される。
また、仮りに連結ピン13が抜け外れ方向に移動した場合には、連結ピン13とテーパ栓25における主体部25aとの摩擦抵抗が、テーパ栓25における仮止め部25cと連結板24との摩擦抵抗より大であることにより、仮止め部25cが連結板24に対して摺動してテーパ栓25が連結ピン13とともに移動し、連結ピン13の縮径変形を阻止する。したがって、連結ピン13が縮径して抜け外れることが確実に防止され、両連結部材1、2の相互の連結が確実に保持される。
【0029】
また、連結状態においては、両連結部材1、2内に埋設された両角座6、30が、引き抜き力に対して大きな抵抗力となり、強固な連結状態が保持される。
尚、本発明は、上記のようなコンクリートセグメント以外の部品相互の連結に適用できることは勿論である。
【0030】
【発明の効果】
本発明のセグメントの雄継手具は、その連結ピンを連結部材から突出させるとともにナットと調整部材の前端面のみ連結部材の接合端面に露出するようにして連結部材内に埋設する。
【0031】
この埋設状態において、空隙保持用パイプとアンカーバー間に空隙が形成され、かつ、弾性材料からなる調整部材と、弾性材料からなる座部材が存在することによって、アンカーバーの先端が、その直径方向に移動できる。したがって、連結前において連結ピンが所定位置より若干偏心していても連結ができ、連結作業が容易になる。

A plurality of the male joints 3 are provided on the joining side surfaces of the pair.
[0025]
Next, the connection operation will be described.
The connection pin 13 is screwed to the nut 8 at the connection site. One connecting member 1 faces the other connecting member 2 so that the connecting pin 13 faces the case 20. Then, one connecting member 1 is moved to the other connecting member 2, and the connecting pin 13 is pushed into the case 20.
[0026]
At the time of insertion, the connecting pin 13 is guided into the insertion hole 20a by the engagement between the tapered portion 16b and the guide surface 22. At this time, when the connecting pin 13 and the case 20 are slightly eccentric, the adjusting member 9 made of an elastic material exists on the outer peripheral portion of the nut 8 and the outer peripheral portion of the anchor bar 5 is provided by the gap holding pipe 10. The presence of the gap 12 causes the connecting pin 13 to move in the diametrical direction, that is, toward the axis of the case 20, so that the axis of the connecting pin 13 matches the axis of the case 20 even in the eccentric state as described above. The connecting pin 13 is securely fitted into the case 20.
[0027]
When one connecting member 1 is further moved, the connecting pin 13 is reduced in diameter by the split groove 19 and slides into the insertion hole 20a to enter. When the connecting pin 13 is further advanced, the taper plug 25 is fitted into the hole 18, the diameter of the connecting pin 13 is increased, the locking flange 16 a is fitted into the locking groove 23, and the locking surface 16 c Face the locking surface 23a of the locking groove 23 and lock each other. In this engaged state, the two connecting members 1 and 2 are in the joined state in which they are closest to each other.
[0028]
By locking as described above, the connection pin 13 is prevented from coming off and the connection members 1 and 2 are connected to each other.
Also, if the connecting pin 13 moves in the disengagement direction, the frictional resistance between the connecting pin 13 and the main body 25a of the tapered plug 25 increases due to the friction between the temporary fixing portion 25c of the tapered plug 25 and the connecting plate 24. When the resistance is larger than the resistance, the temporary fixing portion 25c slides with respect to the connecting plate 24, and the tapered plug 25 moves together with the connecting pin 13, thereby preventing the connecting pin 13 from being reduced in diameter. Accordingly, the connecting pin 13 is reliably prevented from being reduced in diameter and coming off, and the mutual connection of the two connecting members 1 and 2 is reliably maintained.
[0029]
In the connected state, the corner seats 6, 30 buried in the connecting members 1, 2 have a large resistance to the pulling force, and the strong connected state is maintained.
The present invention can of course be applied to the connection of parts other than the concrete segments as described above.
[0030]
【The invention's effect】
The male joint of the segment of the present invention is embedded in the connecting member such that the connecting pin protrudes from the connecting member and only the front end surfaces of the nut and the adjusting member are exposed at the connecting end surface of the connecting member.
[0031]
