To this end, the flange fixing body 56 is formed in a plate-like structure, the lower portion in close contact with the flange 200 is preferably formed to have a groove structure similar to the outer shape of the flange 200. In addition, the flange fixing body 56 is in close contact with the support plate 53 in front of the expansion part 250 of the flange 200 in the state inserted into the insertion holder 54, so that the flange 200 does not move in the axial direction. It is preferable that it is comprised so that it may be fixed.

The flange fixing body 56 may be configured to be fixed to the flange insert 52 by a screw fastening method or the like in a state where the flange 200 is fixed.

On the other hand, the flange clamp 50 is disposed so as to face the center of the pipe clamp 30 concentric (located on the same axis) so that the center of the flange 200 and the pipe 100 can be easily coupled It is preferable to be.

Next, the support 70 is composed of a plurality of rod-like structure, through the pipe pedestal 20 and the flange supporter 40 arranged in a row in a state spaced apart from each other to maintain a constant or fixed spacing do.

The support 70 is disposed in a horizontal direction orthogonal to the support plate 22 and the flange supporter 40 and installed in a structure for interconnecting and fixing the support plate 22 and the flange supporter 40 to each other. 22 and four flange supports 40 may be installed in all four corners, one at each corner, as shown in the figure.

Here, some of the support plate 24 (for example, the middle support plate) of the support plate 22 may be installed to be able to move back and forth along the support 70, the flange support 40 also supports 70 It is installed to be able to move horizontally along.

It is preferable that bushings 72 and 74 are installed on the support plate 24 and the flange supporter 40 that are movably coupled to the supporter 70.

The reason for constituting the support plate 24 to be movable is to stably support by setting the support position according to the length and type of the pipe, such as when the length of the pipe 100 is short.

Next, the flange pressurizing device 80 is configured to allow the operator to move the flange 200 forward in the pipe direction by turning the pressure handle 82 so that the flange 200 can be fitted around the pipe 100. .

The flange pressing device 80 is screwed to the pressing support 81 in a state connected to the pressing support (81) fixed to the support 70, the flange support 40, and rotates the flange support (40) It may be configured to include a pressure handle 82 to move.

Accordingly, when the screw shaft 83 is rotated while holding the handle 85, the screw shaft 83 moves forward and backward in the axial direction so that the flange 200 mounted on the flange support 40 moves in the pipe 100 direction. It is configured to be coupled to move.

Now, a method of fixing the flange 200 to the pipe 100 using the pipe 100 flange 200 connecting device configured as described above will be described.

The pipe 100 is fixed using the pipe support 20 and the pipe clamp 30. That is, the pipe 100 is fixed to the pipe 100 by placing the pipe 100 on the pipe pedestal 20 while the pipe clamp 30 is open, and fastening the pipe clamp 30 with the fastening member 36. .

In addition, the flange 200 is attached to the flange clamp 50. That is, the flange 200 is inserted into the flange insert 52 in a state where the flange 56 is separated, and then the flange 200 is inserted into the flange 200 to fix the flange 200.

As such, when the pipe 100 and the flange 200 are respectively fixed to the apparatus for mounting the flange to the pipe of the present invention, the end of the pipe 100 to which the flange 200 is to be coupled or the inner circumferential surface of the flange 200 Apply or install an adhesive member or fixing band for mutual adhesion and fixation on the side. At this time, the adhesive member or the fixing band is preferably configured on the pipe 100 side.

In this way, when the adhesive member etc. are comprised in the pipe 100, the handle 85 of the flange pressurizing device 80 is rotated, and the flange support body 40 is gradually moved to the pipe 100 direction. At this time, the flange supporter 40 moves toward the pipe 100 along the supporter 70.

If the flange support 40 continues to move, the flange 200 mounted on the flange clamp 50 starts to fit around the pipe 100 and moves further, and if moved by a predetermined length, the operation of the handle 85 is stopped. Stop it.

In this state, when a predetermined time elapses, the adhesive member is hardened and the flange 200 is coupled to the end of the pipe 100 to be fixed.

Of course, when the flange 200 is coupled to the end of the pipe 100, immediately in the pipe clamp 30 and the flange clamp 50, to separate the pipe 100 and the flange 200 coupled to each other and then the adhesive member, etc. It is also possible to allow this to cure.

In addition, in the case where the pipe 100 and the flange 200 are made of metal, the flange 200 and the pipe 100 are basically attached and then separated from the apparatus and welded to the pipe clamp 30 and the flange clamp 50. It is also possible to install the flange 200 by welding in a combined state as it is.

As described above, it is preferable that the pipe and the flange are joined using the apparatus of the present invention, and then the pipe and the flange are attached or welded to each other by using a suitable method known in the art and according to the material and the implementation conditions.

The drawings are shown in the center, and other portions are omitted. Description will also be described with reference to the configuration of the flange clamp 50A, and repeated descriptions will be omitted. In addition, components similar to the same as those of the above-described embodiment will be described with the same reference numerals.

The second embodiment is configured such that the pipe 100 and the flange 200 of various sizes can be commonly used through the flange clamp 50A. That is, referring to FIG. 8, the pipe 101 and the flange 201 having a relatively small diameter may be connected to the pipe 102 and the flange 202 having a relatively large diameter.
