Description

【0001】
【発明の属する技術分野】
本発明は、PC鋼より線若しくはポリエチレン(PE)被覆を施したPC鋼より線を、橋梁等にケーブルとして一括して配線するためのケーブルの配線方法と配線装置とに関する。
【0002】
【従来の技術】
従来、例えば、1ケーブルを構成する複数のPC鋼より線を工場において予め所定の長さに測長して、それを束ねながらのキャリアに巻き取らせ、該キャリアを運搬車で建築現場に搬入し、そのキャリアからケーブルを引き出して、配線するものである。
【0003】
【発明が解決しようとする課題】
しかしながら、橋梁等の構造物の大型化に伴い、大容量のケーブルが要求され、1ケーブルを構成するPC鋼より線の数も増大して、その長さや重量も増えて特殊なキャリアやこれを扱うキャリア及び重機等が必要となって、コストの上昇を招いている。また、ケーブル長が長くなると、PC鋼より線は単に束ねられているだけなので、配線作業中に、ケーブルの形が崩れてPC鋼より線同士がよじれたり捻れたりするという課題がある。本発明に係るケーブルの配線方法と配線装置は、このような課題を解消するために提案されるものである。
【0004】
【課題を解決するための手段】
本発明に係るケーブルの配線方法の上記課題を解決するための要旨は、1ケーブルを構成する所要長さの複数のPC鋼より線をキャリアに分割して巻き取り、該キャリアを構造物の構築現場に搬入した後、前記各キャリアからPC鋼より線を引き出してその先端部を所要形状に束ねてパイロットキャップでクランプし、キャリアとパイロットキャップとの間で、適宜数の捌きローラ装置を配設し、当該捌きローラ装置とパイロットキャップとの間に成型ローラを配設し、前記パイロットキャップに引き込みワイヤーを連結して、PC鋼より線を所要形状に連続成形しながら引き込むことである。
【0005】
本発明に係るケーブルの配線装置の要旨は、所望測長のPC鋼より線を巻き取るキャリアと、該キャリアから引き出されたPC鋼より線を上下方向に一列に併設するバーチカルガイドと、該バーチカルガイドからのPC鋼より線を上下・左右に位置規制する捌きローラ装置と、該捌きローラ装置からのPC鋼より線を所要の形状に揃える成型ローラとでなることである。
【0006】
本発明に係るケーブルの配線方法と配線装置によれば、複数のキャリアに所望の長さに切断されたPC鋼より線を巻き取り、建築現場に搬入するようにすることで、構造物の大型化に伴うケーブルの重量化に対して、細分化して対応させることが出来る。
【0007】
所要形状にした上で複数のキャリアから引き出した複数のPC鋼より線の先端部を、まず、仮クランプで束ね、パイロットキャップを取り付け、配線装置を挿通させ引き込みワイヤーで引き込むことで、複数のPC鋼より線を所要形状(例えば、六角形)に交錯することなく連続成形して束ね、1ケーブルとして配線することが出来るものである。
【0008】
【発明の実施の形態】
次に、本発明に係るケーブルの配線方法と配線装置について図面を参照して説明する。図1乃至図2は、ケーブルの配線方法の概略実施態様を示すもので、PC鋼より線1は、所定の長さに測長されたもので、必要数(例えば、19本)がキャリア2,2に分割(例えば、10本,9本)して巻き取られている。よって、ケーブルが大型化しても、2t程度の通常のキャリアを用いることができ、その運搬にも特殊な車両を必要とするものではない。
【0009】
前記PC鋼より線1の測長及びキャリア2への巻き取り作業は、例えば、工場にて行うものである。そして、キャリア2を建築現場に搬入して、アンリーラー2aの上に載置する。当該現場においては、配線装置3が用意される。この配線装置3の各構成について、図3乃至図6を参照して詳細に説明する。
【0010】
配線装置3の基台3a上に、先端側から後端側へ順にバーチカルガイド4、捌きローラ装置5、六角ローラ6が各々設けられている。前記バーチカルガイド4は、図3に示すように、所要の間隔をおいて対向面に回転自在な縦ローラ4c及びガイド板4dを配設してなるガイド部材4a,4bにより、前記アンリーラー2aの上に置かれたキャリア2から引き出された所要複数本のPC鋼より線1を上下方向に一列に揃えて配設し、PC鋼より線1,1,…が互いに交錯しないようにガイドするものである。
【0011】
前記捌きローラ装置5は、図4(イ)、(ロ)に示すように、框体6に左右方向に所要間隔を置いて上下方向に垂設した回転自在なローラ7,7を有して形成された縦捌きローラ5aと、図5に示すように、框体8に上下方向に所要間隔をおいて左右方向に平行に架設した回転自在なローラ9を有して形成された横捌きローラ5bとで構成されている。前記縦捌きローラ5aは、PC鋼より線1の左右方向の位置規制をするものであり、一方のローラ7は、取り付け部の長孔6aと調節ネジ部6bとによって、左右方向に移動調整可能にされている。また、横捌きローラ5bにおけるローラ9,9間の上下間隔は、PC鋼より線1の直径の2倍未満にして、該PC鋼より線1が交錯しないように設定されている。
【0012】
前記六角ローラ(成型ローラ)10は、図6に示すように、PC鋼より線1を所定の形状になるように束ねて成形するものであって、例えば、六角ローラである場合には、ヒンジ11aにより開閉自在でボルトナット等で固定する六角形状の框体11の各々の内壁面に、コ字型の支持部材11bと、該支持部材11bに軸装される軸11cと、該軸11cにベアリングを介して回転自在に軸着されるローラ12とを設ける。当該框体11の中心に向かって六角状に配置されて支持された六個の前記ローラ12により、各PC鋼より線1が束ねられて六角形状に成形されるものである。
【0013】
なお、基台3aの先端と後端において、左右方向にガイド用のローラ13,14が配設されている。
【0014】
このような配線装置3を使用してPC鋼より線1を所定形状に連続成形する方法について説明する。まず、前記各キャリア2,2からPC鋼より線1を引き出してその先端部を所要形状(六角形)に束ねてパイロットキャップ15でクランプする。
【0015】
前記キャリア2とパイロットキャップ15との間で、バーチカルガイド4と捌きローラ装置5とを配設し、当該捌きローラ装置5とパイロットキャップ15との間に成型ローラ10を配設し、各PC鋼より1を適宜配置になるように挿通して、その後、前記パイロットキャップ15に引き込みワイヤーを連結して、PC鋼より線1を所要形状に連続成形しながら所定方向に引き込む。すると、PC鋼より線1は、キャリア2から引き出されてバーチカルガイド4で上下方向に一列に整列され、そして、縦捌きローラ5aと横捌きローラ5bとでなる捌きローラ装置5で上下左右に振り分けられ、更に、成型ローラ10で所要形状に成形され、一つのケーブルとなったものを定着部間に架設し緊張・定着させるものである。
【0016】
【発明の効果】
以上説明したように、本発明に係るケーブルの配線方法は、1ケーブルを構成する所要長さの複数のPC鋼より線をキャリアに分割して巻き取り、該キャリアを構造物の構築現場に搬入した後、前記各キャリアからPC鋼より線を引き出してその先端部を所要形状に束ねてパイロットキャップでクランプし、キャリアとパイロットキャップとの間で、適宜数の捌きローラ装置を配設し、当該捌きローラ装置とパイロットキャップとの間に成型ローラを配設し、前記パイロットキャップに引き込みワイヤーを連結して、PC鋼より線を所要形状に連続成形しながら引き込むケーブルの配線方法なので、複数のキャリアに所望の長さに切断されたPC鋼より線を巻き取り、建築現場に搬入するようにすることで、構造物の大型化に伴うケーブルの重量化に対して、既存の輸送手段で柔軟に対応させることが出来るという優れた効果を奏するものである。
また、所要形状に束ねるパイロットキャップを引き込みワイヤーで引き込むことで、複数のPC鋼より線を所要形状に連続成形して束ね、一ケーブルとして容易に配線することが出来るものであるという優れた効果を奏するものである。
【0017】
本発明に係るケーブルの配線装置は、所望測長のPC鋼より線を巻き取るキャリアと、該キャリアから引き出されたPC鋼より線を上下方向に一列に併設するバーチカルガイドと、該バーチカルガイドからのPC鋼より線を上下・左右に位置規制する捌きローラ装置と、該捌きローラ装置からのPC鋼より線を所要の形状に揃える成型ローラとでなるので、多数のPC鋼より線からなる所定形状のケーブルを交錯することなく容易に連続成形することができるという優れた効果を奏するものである。

The required multiple PC steel strands drawn from the carrier 2 placed in the vertical direction are arranged in a line in the vertical direction, and the PC steel guides the wires 1, 1,... So as not to cross each other. is there.
[0011]
As shown in FIGS. 4 (a) and 4 (b), the roller device 5 has rotatable rollers 7 and 7 vertically suspended from the housing 6 with a required interval in the left-right direction. As shown in FIG. 5, the formed vertical rolling roller 5 a and the horizontal rolling roller formed with a rotatable roller 9 laid in parallel in the left-right direction at a predetermined interval in the vertical direction as shown in FIG. 5. 5b. The vertical roller 5a regulates the position of the PC steel wire 1 in the left-right direction, and one roller 7 can be moved and adjusted in the left-right direction by means of a long hole 6a in the mounting portion and an adjusting screw portion 6b. Has been. The vertical distance between the rollers 9 and 9 in the horizontal roller 5b is set to be less than twice the diameter of the wire 1 of PC steel so that the wire 1 of the PC steel does not cross.
[0012]
As shown in FIG. 6, the hexagonal roller (molding roller) 10 is formed by bundling PC steel wire 1 into a predetermined shape. For example, in the case of a hexagonal roller, it is a hinge. 11a, a U-shaped support member 11b, a shaft 11c pivotally mounted on the support member 11b, and a shaft 11c. There is provided a roller 12 rotatably mounted via a bearing. By the six rollers 12 arranged and supported in a hexagonal shape toward the center of the casing 11, the wires 1 are bundled from each PC steel and formed into a hexagonal shape.
[0013]
Guide rollers 13 and 14 are disposed in the left-right direction at the front and rear ends of the base 3a.
[0014]
A method for continuously forming the wire 1 from PC steel into a predetermined shape using such a wiring device 3 will be described. First, the wire 1 is pulled out from each of the carriers 2 and 2 from the PC steel, and its tip is bundled into a required shape (hexagon) and clamped by the pilot cap 15.
[0015]
Between the carrier 2 and the pilot cap 15, a vertical guide 4 and a rolling roller device 5 are disposed, and a molding roller 10 is disposed between the rolling roller device 5 and the pilot cap 15, and each PC steel. 1 is inserted so as to be properly arranged, and then a pull-in wire is connected to the pilot cap 15, and the PC steel wire 1 is drawn in a predetermined direction while being continuously formed into a required shape. Then, the PC steel strand 1 is pulled out from the carrier 2 and aligned in a vertical line by the vertical guide 4, and is distributed vertically and horizontally by a rolling roller device 5 comprising a vertical roller 5a and a horizontal roller 5b. In addition, what is formed into a required shape by the forming roller 10 and becomes one cable is installed between the fixing portions to be tensioned and fixed.
[0016]
