れていた。<Problems with conventional technology> In the past, when a group of steel wires was tied together and pulled into a predetermined cavity and inserted, the connecting ends of the steel wires were inserted into a steel plate having holes, and the wires were wedged one by one. The method used was to fix the wire with a wire or with a crimp grip, which was then connected to a steel wire for lead-in.
しかし、これらの方法では、接続部の外径が大きくなる
ため、限られた径の空洞部内には挿入が困難になるか、
あるいはてきない可能性がある。However, with these methods, the outer diameter of the connection part increases, making it difficult to insert it into a cavity with a limited diameter, or

〈本発明の構成〉
以下、図面を参照しながら本発明の一実施例について説

An example will be explained in which a group of Ci wires is drawn into and inserted into a PC sheath tube.
〈イ〉結束具（第１．２図）
本発明の結束具１は、スリーブ管１１、スペーサー１２
、圧着材１３よりなる。<A> Binding tool (Fig. 1.2) The binding tool 1 of the present invention includes a sleeve pipe 11, a spacer 12
, a pressure bonding material 13.
（１）スリーブ管
スリーブ管１１は、比較的圧縮力によって変形しやすい
鋼管である。(1) Sleeve pipe The sleeve pipe 11 is a steel pipe that is relatively easily deformed by compressive force.
スリーブ管１１の材質には例えば、鉛なとを使用するこ
とが考えられる。For example, lead may be used as the material for the sleeve tube 11.
また、スリーブ管１１の径は、後述するスペ・−ザー１
２によって束ねたＰＣ鋼線２群か、挿入できる大きさに
形成する。In addition, the diameter of the sleeve pipe 11 is determined by the spacer 1 described later.
2 groups of PC steel wires bundled together or formed into a size that can be inserted.
（２）スペーサー
スペーサー１２は、ＰＣ鋼線２群を一定間隔に保つため
、各ＰＣ鋼線２を挿入する複数の孔を有する円盤で°あ
る。(2) Spacer The spacer 12 is a disk having a plurality of holes into which each PC steel wire 2 is inserted in order to maintain the two groups of PC steel wires at a constant interval.
また、スペーサー１２は、スリーブ管１１を圧縮すると
きに一緒に圧縮されるため、合成樹脂などによって形成
し、弾力性を持たせる。Furthermore, since the spacer 12 is compressed together with the sleeve tube 11 when it is compressed, it is made of synthetic resin or the like and has elasticity.
（３）圧着材
圧着材１３は、例えば、角部を有する超硬質チップを顆
粒状にしたものなどが考えられる。(3) Pressure bonding material The pressure bonding material 13 may be, for example, granulated ultra-hard chips having corners.
この圧着材１３は、ＰＣ鋼線２群を挿入したスリーブ管
１１内に充填され、スリーブ管１１の圧縮に１よってＰ
Ｃ鋼線２群に圧着し、ＰＣ鋼線２群を確実に定着するも
のである。This crimping material 13 is filled into the sleeve tube 11 into which two groups of PC steel wires are inserted, and is compressed by 1 when the sleeve tube 11 is compressed.
It is crimped onto the second group of C steel wires and securely fixes the second group of PC steel wires.
く口〉結束具の組立（第１図）
先ず、ＰＣ鋼線２群の最端部と、やや間隔をおいた所に
スペーサ−１２を取り付け、ＰＣＩ線２群をスリーブ管
１１内に挿入する。Assembling the binding tool (Fig. 1) First, attach the spacer 12 to the end of the two groups of PC steel wires and at a slight distance apart, and insert the two groups of PCI wires into the sleeve tube 11. .
ぞして、スリーブ管１１内には圧着材１３を充填し、２
つのスペーサー１２をスリーブ管１１の両端部近傍に位
置させて、スリーブ管１１の両端部を閉塞し、蓋の役目
を兼ねさぜることかできる。Then, the inside of the sleeve pipe 11 is filled with the crimping material 13, and the 2
Two spacers 12 can be placed near both ends of the sleeve tube 11 to close both ends of the sleeve tube 11 and serve as a lid.
組立が完了した後、スリーブ管１１を周囲から圧縮する
。After the assembly is completed, the sleeve tube 11 is compressed from the periphery.
このとき、圧着材１３に超硬質チップを用いた場合には
、その角部が圧縮によって、ＰＣ鋼線２群及びスリーブ
管１１に食い込み、ＰＣ鋼線２群は非常に強力に結束さ
れる。At this time, if an ultra-hard tip is used as the crimping material 13, the corners of the tip will bite into the second group of PC steel wires and the sleeve tube 11 due to compression, and the second group of PC steel wires will be bound very strongly.
ところで、圧着材１３をスリーブ管１１内に充填しない
で、スリーブ管１１を圧縮した場合について考えると、
結束したＰＣｍＣｍ群の中心部イτ１近のＰＣ鋼線２は
、周囲のＰＣＩ線２との表面接触による摩擦抵抗が発生
するのみてあり、引込時の引き抜き荷重に充分に抵抗で
きず、引き抜けてしまうおそれがある。By the way, considering the case where the sleeve pipe 11 is compressed without filling the sleeve pipe 11 with the crimp material 13,
The PC steel wire 2 near the center τ1 of the bundled PCmCm group only generates frictional resistance due to surface contact with the surrounding PCI wire 2, and cannot sufficiently resist the pull-out load during pull-in, and is not pulled out. There is a risk that this may occur.
しかし、本発明の場合は、上記のように圧着材１３をス
リーブ管１１内に充填して、スリーブ管１１を圧縮する
ため、ｐｃｇＩ４線２群の中２群（＝ｆ近のＰＣ鋼線２

擦抵抗を得ることができる。However, in the case of the present invention, in order to compress the sleeve tube 11 by filling the crimping material 13 into the sleeve tube 11 as described above, the PC steel wires of the two groups of PCG I4 wires (= PC steel wires near f)
A very large frictional resistance can be obtained by the pressure bonding material 13 filled around the periphery.
従って、引込時の引き抜き荷重に充分抵抗することがで
き、引き抜けてしまうおそれがない。Therefore, it can sufficiently resist the pull-out load during retraction, and there is no risk of it being pulled out.

要は、結束したＰＣ鋼線２群の接続端部に、引込用ＰＣ
Ｍ線３を、引込時の引き抜き荷重に抵抗できるように接
続できればよい。In short, connect the lead-in PC to the connecting end of the two groups of bundled PC steel wires.
It is sufficient if the M wire 3 can be connected in such a way that it can resist the pull-out load during pull-in.

By penetrating the steel wire 3 into the sheath pipe 5 and pulling the pulling JUP C steel wire 3, the two groups of PC steel wires bound with the binding tool 1 are drawn into the sheath pipe 5 and inserted.

方法か採られていた。<B> Conventionally, when bundling the W4 wire group and pulling it into a predetermined cavity, the connecting ends of the steel wires were inserted into a copper plate with holes, and the wires were wedged one by one and fixed, or The method used was to fix it with a crimp grip and connect it to a steel wire for lead-in.
しかし、これらの方法ては、接続部の外径が大きくなる

、非常に強い結束を得ることができる。In contrast, in the present invention, a very strong bond can be obtained by simply positioning a crimping material between the steel wires and compressing them from the surroundings using a relatively easily deformable steel pipe.
即ち、鋼線群と引込用鋼線との接続部を圧縮して結束す
るため、接続部の外径が大きくならすに済む。That is, since the connecting portion between the steel wire group and the lead-in steel wire is compressed and bundled, the outer diameter of the connecting portion can be made larger.
従って、接続部の径を従来よりも小さく結束でき、鋼線

引き抜けてしまうおそれかある。Therefore, the diameter of the connecting part can be bundled smaller than before, and the steel wire group can be easily drawn and inserted into the cavity. When bundling, only the steel wires located on the outer periphery of the steel wire group will bite into the crimping grip and be fixed, or the steel wires near the center will not bite into the crimping grip, so it will be difficult to tie the steel wires when pulling in. It cannot sufficiently resist the pull-out load,
There is a possibility that it may be pulled out.
