置を決定する。 In the past, when such a flange attachment work was performed, the procedure was generally as shown in FIG. 1. That is, first, with the flange 2 inserted into the pipe 1, as shown in a, the flange 2 is inserted into the pipe opening so that a welding margin 3 of the correct width is formed between the inner peripheral surface of the flange 2 and the mouth end surface of the pipe 1. Move it slightly forward from the edge. Next, while maintaining this welding allowance 3, rotate the flange 2 to align the holes ( hole swing). Next, as shown in c, tack 5 1 is attached to one point of the welding allowance 3.
In this state, use a level etc. to adjust the flange 2.
Adjust the angle so that it is attached to the pipe 1 at the correct angle. Next, as shown in d, tacking 52 is performed at a position diagonal to the position of tacking 51 . After temporarily attaching these two points 5 1 and 5 2 , it is detected whether the mounting angle at a position 90° phased with the direction in which the angle of the pipe 1 and flange 2 was adjusted in step c above is correct, and the hammer After correcting the angle by tapping lightly, the remaining two points are temporarily attached 5 3 and 5 4 as shown in e to determine the correct mounting position of the flange 2.

It consists of a cylinder having a bottom 20 with a diameter smaller than the inner diameter of the pipe 1, and is fixed to the back surface of the thick walled part 21 of the seat plate 11. The main body 12 also has a plurality of elongated holes 22 formed on the circumferential surface and extending along the axial direction.
4 are crimped onto the inner peripheral surface of the pipe 1, and chucks 13 are provided radially so as to be retractable in and out of the main body 1, respectively. Each of these chucks 13 has an inner end 25 with a tapered surface, and this inner end 25 is connected to a conical body 27 provided inside the main body 12 of a shaft 26 that is supported through the seat plate 11 and the center of the main body 12. Supported by.
This conical body 27 is screwed onto a threaded portion 28 provided inside the main body 12 of the shaft 26, and when the shaft 26 is rotated via a handle 29 provided at the outer end of the shaft 26, the shaft 26 is rotated. It moves in the axial direction, thereby allowing the chuck 13 to move in and out of the main body 12. The outer end 25 of each chuck 13 is held down by a rubber ring 30 fitted around the outer periphery of the main body 12 so that it does not slip out of the elongated hole 22, for example.

する。 To attach the flange 2 using this attachment device, first, as shown in FIG. At this time, the position of the seat plate 11 is correctly corrected using the protractor scale 19 and the pendulum needle 17 on the surface. Then, by rotating the shaft 26, each chuck 13 is equally projected through the cone 27, and the outer end 24 of each chuck is attached to the pipe 1.
The centers of the seat plate 11 and the main body 12 are aligned with the center of the pipe 1 by crimping them onto the inner peripheral surfaces of the pipe 1. In this state, the stepped portion 1 on the back side of the seat plate 11
Since the outer peripheral surface of 4 and the outer peripheral surface of the pipe 1 exactly match, the flange 2 inserted in advance into the pipe 1 is brought into close contact with the back surface of the thin peripheral portion 15 of the seat plate, and in this state, the bolts of the flange 2 are tightened. The position of the flange 2 is fixed by aligning the position of the hole 4 with the positioning hole 16 of the seat plate 11 and inserting a pin.
Once the mounting position of the flange 2 has been determined in this way, temporary attachments 31 are performed in about three places on the back of the flange 2 and the outer peripheral surface of the pipe 1, and the chuck 13 is attached.
Remove the device from pipe 1 by loosening the .
As shown in FIG. 5, when the device is removed, an appropriate welding margin 3 is formed between the inner circumferential surface 23 of the flange 2 and the pipe opening end surface 32, so the necessary welding is performed on this portion to close the flange 2. Secure it completely to pipe 1.

倒な角度合わせを全く不要とすることができる。 As stated above, in the mounting device of the present invention,
With the seat plate 11, which serves as a reference for positioning the flange 2, in close contact with the pipe mouth end surface 32, the main body 12
Since the plurality of chucks 13 provided in the seat plate 11 are evenly crimped onto the inner peripheral surface of the pipe, the center of the seat plate 11 can be accurately aligned with the pipe center, and the position with the positioning hole 16 provided in the seat plate 11 can be adjusted. By alignment (drilling), the mounting position of the flange 2 relative to the pipe mouth end can be set extremely quickly. Of course, when the flange 2 is set on the back side of the seat plate 11 as described above, the seat plate 11
is fixed to the pipe mouth end face 32 at a correct angle, so the angle of the flange 2 is at an accurate position with respect to the pipe mouth end, and the troublesome angle adjustment by conventional installation work can be completely eliminated.

代３の設定が全く面倒なく行える。 In addition, since the seat plate 11 has a stepped portion 14 having the same diameter as the outside diameter of the pipe 1 on the back surface and has a thin peripheral portion 15, the flange 2 is in close contact with the back surface of the thin peripheral portion 15. If the device is removed after the temporary attachment 31 is performed, an appropriate welding distance 3 can be obtained between the pipe mouth end surface 32 and the flange inner circumferential surface 23, so the welding distance 3 can be set without any trouble.
従つてこの装置を用いることにより、フランジ
取付作業が従来の手作業に比較し著しく簡便にし
