2. Description of the Related Art Hitherto, there has been no adapter jig for the above-mentioned chain for fixing a punch. Therefore, when the chain is wound around the outside of the joint body to fix the drilling machine against the peripheral surface of the joint body, the chain is passed through the gap between the bolt and the joint body, and the chain is passed through the peripheral surface of the joint body. Was wound directly. However, in this method, if there is a portion where the gap between the bolt and the joint body is small due to external force acting due to land subsidence or the like and the gap between the bolt and the joint body is reduced, the chain is passed through the gap. There was a drawback that it was not possible. Therefore, in such a case, the chain is extended outside the bolt in a portion where the gap is reduced, and the chain is applied to the bolt from the outside, and the chain is wound from the peripheral surface of the joint body to the outside surface of the bolt. Was.

However, as described above, according to the method in which the chain is applied to the bolt from the outside and the chain is wound around the outside of the joint body, for example, the chain is wound while the chain is wound. If the ridges of the chain are on the bolts, and the ridges of the chain are displaced by the vibration of the machine during drilling by the drilling machine and the valleys are on the bolts, the chain is likely to be loosened. However, there has been a drawback that the fixing of the drilling machine to the peripheral surface of the joint body becomes unstable and the drilling cannot be performed reliably. The present invention solves the above-mentioned conventional drawbacks, and even if the gap between the bolt and the joint body is too small to allow a chain to pass therethrough due to deformation caused by land subsidence or the like, An object of the present invention is to ensure that a drilling machine can be securely applied to and fixed to a peripheral surface of a joint main body until drilling is completed.

That is, for example, a wound body having a width extending between the pair of dresser flanges of the pipe joint is prepared, and the wound body is wound while applying both ends of the wound body to the outer peripheral surfaces of both dresser flanges. Then, the wound body is fixed to the projecting end of the bolt or the like of the pipe joint part by the fixing part. With the wound body wound in this way, a receiving portion for receiving the drilling machine fixing chain is formed on the front surface of the wound body along the circumferential direction of the pipe joint. Thus, the chain can be wound around a winding body while being applied to the receiving portion, and the punch can be applied and fixed to the peripheral surface of the joint body. Since the receiving portion is formed in a larger number than the bolt, in a portion where the gap between the bolt and the joint body is small as in the related art, the chain is applied to the bolt from the outside thereof, and the chain is The chain can be received in more places than when wrapped around the outside of the joint body.For example, it is possible to prevent the ridge of the chain from climbing onto the bolt when the chain is wound. it can.

Accordingly, in a part where the gap between the bolt and the joint body is small due to the deformation of the pipe joint as in the prior art, the chain is applied to the bolt from the outside thereof, and The chain can be received in more places as compared to a method in which the chain is wound around the outside of the joint body. For example, it is possible to prevent a state in which the chain ridge is climbed on a bolt when the chain is wound. Therefore, even if the gap between the bolt and the joint body has become so small that the chain cannot pass therethrough due to land subsidence or the like, the drilling machine will continue until the drilling operation is completed. Can be securely applied to and fixed to the peripheral surface of the joint body, and the drilling operation can be stably and reliably performed.
