いとなるというような各種の欠点がある。In order to perform high-quality pipe butt welding, the welding preparation process involves making the grooves to be joined into an appropriate shape, maintaining the grooves at appropriate intervals, and accurately centering the grooves. It is necessary to minimize the discrepancy between the inner surfaces. For this reason, in conventional medium-diameter pipes (about 2 inches to 20 inches in outer diameter), first of all, as shown in Figure 1 (aJ), a plurality of about 3 to 8 pieces are attached to the outer periphery of one side of pipe a and a to be joined. One end of the rectangular plate b... is welded and tacked so that the other end protrudes from the groove C, and then Fig. 1(b)
As shown in the figure, the other side pipe a' is inserted into the cylindrical space formed by the other end sides of the plurality of rectangular plates b...
Adjust the grooves to a proper spacing, and adjust the centering to minimize the discrepancy between the inner surfaces of the grooves, then attach the other end of the rectangular plate b... to the pipe a on the other side. A common method is to temporarily attach the parts and then weld them while holding them in this manner. However, although the above method seems simple, it requires considerable skill to maintain an accurate groove, and the presence of the rectangular plate makes it impossible to weld continuously over the entire circumference of the groove. Not only does it require skill, but it is also prone to welding defects.Furthermore, removing the temporarily attached rectangular plate causes damage to the outer surface of the pipe, and since the rectangular plate is disposable, it is a waste of resources. There are various drawbacks such as:

如何ようにして行なうか等解決すべき点は非常に多い。As an alternative to such rectangular plates, many removable external clamp devices that hold the pipes to be joined from the outside have been proposed. It is very difficult to weld continuously over the entire circumference of the groove, and as with the case of P rectangular plates, the welding process requires skill and welding defects are likely to occur. Along with the drawback of
It is not widely used because it has common drawbacks such as poor performance in correcting discrepancies between the inner surfaces of the grooves. In addition, for large-diameter pipes such as those for pipelines, internal clamp devices that can hold the pipes to be joined from the inside are also used, but these devices are complex and bulky. It is extremely difficult to miniaturize the pipe to the extent that it can be used for medium-diameter pipes, including cost considerations, and even if it were possible to miniaturize it, how would it be possible to perform operations such as fine adjustment of the clamp position? There are many issues that need to be resolved, including whether or not to do so.

Then, the piston 4 moves to the right in the figure against the return spring 10, so that the actuator 2 becomes fixed. After that, the other pipe 1' is brought to a predetermined position from the other side of the hollow base 2,
Then, working fluid is supplied from the fluid supply hose 13 through the fluid introduction port 6 and the fluid communication section I into the pressurizing chamber. Then, the piston 4' moves to the left in the figure against the return spring 10' and is supported via the operating link 9'. The pipes 1゜1' to be joined in a straight-like manner are supported on one side and the other side of the hollow base 2, and their grooves are held in a predetermined positional relationship, and in this state, the grooves are joined over the entire circumference. All types of welding can be performed. In addition, in the above-mentioned operation,
An appropriate measuring tool may be used to fix the pipe 1.1' to the hollow base 2 in a predetermined positional relationship. A hole 19 into which a fitting can be freely fitted and a groove 21 into which a plate 20 can be fitted are provided, and these objects 18 and the plate 19 can be easily positioned by using a jig for the spacing and direction between the pipes 1.1'. When the rod 18 and plate 19 are removed after fixing the pipe 1.1' in a predetermined position, they do not interfere with K-cross welding.

果的に防止し得るという特徴がある。In particular, the present invention is such that a fluid intake port to a pressurizing chamber formed on one side of the hollow base body is communicated with the pressurizing chamber on the other side via a fluid communication portion formed within the guide rod portion. By doing this, both of them are provided on the - side, so when working with the fluid supply hose connected to the fluid inlet, unlike the structure of the present invention, the fluid inlet is provided on each side. In this case, the fluid supply hose connected to the top must be pulled out from the open ends of the pipes on both sides and connected to a pump, etc. Therefore, two sets of such pumps are required. However, the present invention does not have these drawbacks and can be easily operated. In this way, the present invention can easily use liquids such as water and oil as the fluid, and when liquids are used, the movement of the piston can be finely adjusted, the operation is reliable, and the clamping work is easy. 1. It can be done reliably. Further, since the guide rod portion guides the piston, it is possible to effectively prevent the piston from getting stuck in an inclined state.
