移動しなければな５ らないという欠点があつた。As shown in FIG. 1, the conventional outer clamp has two semicircular arc-shaped parts 2 and 3 at the butt joint of the tube body 1.
were connected with pins 4 to surround the outer periphery of tube body 1 and engaged with bolts and nuts 5 to form a link, and tube body 1 was held with tube fixing bolts 6. When it comes to piping of a larger diameter, the weight of the clamp increases because it is an integrated type, and a hoist is required to install, remove, and hold it horizontally, resulting in high costs and low work efficiency. Since a space larger than the radius of the pipe is required on both sides of the pipe to be installed, when other pipes are installed near both sides, it is impossible to work on both sides at the same time while the clamp is in use, and it is difficult to do so after removing the clamp. The disadvantage was that the tube body had to be moved laterally.

Forms a circular chain, and this chain allows 0
and a projecting member that surrounds the joint of the pipe, shortens and tightens the length-adjustable links included in the plurality of links, and is fixed to the outer periphery of the pipe in the vicinity of the joint. The present invention relates to an outer clamp for a pipe joint 5, characterized in that a width-adjusting member is engaged between the link and the link. An example of the present invention will be described with reference to the drawings.
Pipe bodies 1 and 1 to be joined in FIGS. 2 and 3
A circular chain 10 is formed by connecting a plurality of 'o-links 9 each having a tube holding part 11 that straddles the joint T of ', and having a mutually removable binding joint connecting means. This chain surrounds the tube junction T. The plurality of links 9 include links 9 whose lengths can be freely adjusted. By shortening the length of this link 9' and tightening the tubes 1 and 1',
The center of tubes 1 and 1'! 5 can be matched. Examples of links 9 and 9' will be described with reference to FIGS. 4 to 8. Two hook-shaped members 10 are connected via a plate-shaped tube holding part 11.

常に経済的である。This pipe holding part 11 is used to straddle the joint T of the pipe 1.
A recess 1012 with semicircular sides is formed, and pin-shaped protrusions 13 are formed on both sides of the recess 1012, and the hook portions 14 of the links adjacent to the protrusions 13 are engaged to be connected to each other by a pin joint. The hook-shaped member 10 and the tube holding part are integrated with a suitable intersecting angle. Hook 95' with adjustable length
In this example, two pipe holding parts 11' each having a cylindrical body 14 are integrated via a common shaft 8, one of the threaded rods 16 is inserted into the cylindrical body 14, and two hook-like members 1σ each having a cylindrical body are attached. The other of the threaded rods 16 is inserted into the cylindrical body 15, and a nut 17 is screwed onto the threaded rod 16, and the pipe holding portion 11' and the hook-like member 1σ can be displaced by turning the nut 17. can. Next, to explain the means for determining the relative position in the length direction of the tube 1,
The protruding member 18 and the link 9 are engaged with the protruding member 18 and the link 9.
Insert the round arrow 20 (pull pin) between the round arrow 20
By driving a pull pin (pull pin), the tubular body 1 is slightly moved in the longitudinal direction to make an adjustment to open a gap in the joint 7 between the two tubular bodies 1 and 1'. Finally, the joint portion 7 can be welded to connect the pipe body 1 and the pipe body 1. Note that 21 is Maruya 20
This is a hole for inserting a pin or the like to prevent the width adjusting member 19 from coming off when driving. According to the invention,
A ring chain is formed by a plurality of links equipped with mutually removable pin joint coupling means, and this chain surrounds the joint of the pipe, making it easy to attach and detach each link, and without the need for a hoist. Even if the space on both sides of the pipe to be joined is narrow, clamps can be installed, and multiple clamps can be installed. By simply shortening and tightening the length-adjustable link included in the link, the center lines of the connecting piping can be aligned, and the connection between the protruding member fixed to the pipe body and the link can be adjusted. It is possible to easily position the pipe in the longitudinal direction by using the width adjusting member and the round arrow that are engaged in between, improving the quality and work efficiency of the pipe, and the simple structure makes it very economical. .
