【産業上の利用分野】本考案は、融着継手と樹脂管とを
接合する際に用いる接合用治具に関するものである。BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a jig for joining a fusion joint and a resin pipe.

照）。Conventionally, as shown in FIGS. 6 and 7,
A fusion joint a before the fusion, and a fusion part b of the fusion joint a
In order to fix the joint state with the resin tube c inserted into the clamp body d, a receiving portion e in which the resin tube c can be arranged is formed in a substantially U-shaped splittable clamp body d, and the clamp f is clamped by a screw f. There is known a clamp device g configured to fix a resin tube c arranged in a receiving portion e by fastening a main body d (for example, see Japanese Utility Model Laid-Open No. 4-67028).

It is known that a resin tube c is fastened and fixed by fastening portions j provided on both sides of a fitting portion i (for example, see Japanese Patent Application Laid-Open No. 4-19494).

部ｂが歪みを内蔵したまま融着されてしまい、安定した
融着強度が得られなくなってしまう。However, in the case of the above-mentioned conventional clamping device g, only the resin tubes c are fixed to each other.
Since the fusion joint a itself is not fixed and free, the gap between the fusion portion b and the resin pipe c is small at the upper portion and large at the lower portion due to the weight of the fusion joint a, and stable fusion strength is obtained. The inconvenience of not being able to do it arises. For this reason, as shown in FIG. 9, it has been proposed to fix the resin pipe c and the fusion part b of the fusion joint a into which the resin pipe c is to be inserted by the receiving part e. When fixing the attachment portion b, there is an inconvenience that the fixing force tends to vary. as a result,
If fusion is performed while the fusion portion b is excessively tightened, the fusion portion b is fused with a built-in distortion, and stable fusion strength cannot be obtained.

た不都合を生じる。On the other hand, in the case of the fusion joint h having the above-mentioned conventional fastening portion j, the welding portion i is not excessively fastened, but the fastening portion j extending from the welding portion i is not tightened. Due to such a simple structure as fastening, a sufficient centering effect cannot be obtained, resulting in an inconvenience such that it is merely of the degree of retaining.

ないといった不都合を生じることととなる。As shown in FIG. 9, when such a welding operation is performed, if the resin pipe c is not sufficiently inserted into the fusion joint a, a step k may be formed on the inner surface or the resin pipe c may have a step k. Since the molten resin may protrude in the portion, the resin pipe c is inserted up to the position m of the marked line previously written on the resin pipe c to perform the fusion work. However, on the other hand, when the resin tube c is fixed by the clamp device g or the like at the time of fusion, in order to obtain a sufficient centering effect, the portion of the resin tube c facing the end surface of the fusion portion b, that is, the marking line Is fixed by the receiving portion e, which causes a disadvantage that it is not possible to confirm whether or not the resin tube c is sufficiently inserted at the time of fusion.

It is another object of the present invention to provide a joining jig that can prevent insufficient insertion of a resin tube.
