It comprises a mounting member 21 having a flange portion 21a and a cylindrical portion 21b, and a holding member 22 detachably held in a holding hole 21c of the cylindrical portion 21b. The mounting member 21 has a flange 21
A cylindrical portion 21b is vertically provided at a position where the cylinder axis is eccentric from the center of the flange portion 21a. The left and right semicircular cylindrical sections 21b1 forming the cylindrical section 21b are connected by hinges 21d at their adjacent one side edges, and the hinge 21d is used as a fulcrum, and the left and right half of the flange section 21a is formed. The circular ring-shaped flange portion 21a1 and the left and right cylindrical portions 21b1 are formed so as to be openable and closable. The pivot portion of the hinge 21d is located on a vertical line immediately below the outer edge of the mating surface of the left and right flange portions 21a1. On the other side edge of the left and right tubular portions 21b1, a stopper 21e is provided on one tubular portion 21b1 side, and the other tubular portion is provided.
A to-be-stopped portion 21f is provided on the to-be-stopped portion 21b, and the stopper 21e is locked to the to-be-stopped portion 21f, so that the flange portion 21a and the tubular portion 21b can be locked in a closed state, and the same. The locked state is changed from the stopper 21f to the stopper 21.
By removing and releasing e, the flange portion 21a and the cylindrical portion 21b can be opened. Further, the flange portion 21a1 has a slit-shaped or hole-shaped wire passing portion 21a2 shown in the drawing.

The holding member 22 is a split cylindrical member having left and right holding sections 22a having a semicircular cross section. The tube holding hole 22b is formed at a position where the hole axis is eccentric from the cylinder axis. is there. The left and right holding portions 22a are each provided with a concave groove 22c in the middle of the hole surface of the tube holding hole 22b, and a convex portion 22d is provided in the middle of the outer surface in the concave guide groove 21g in the middle of the holding hole 21c. It is protruded so as to be detachable and playable, and can be rotated at an appropriate rotation angle by being guided by the concave guide groove 21g, and is prevented from moving out of the holding hole 21c in the axial direction by being prevented from moving in the axial direction. Is held in. And, the holding hole of the cylindrical portion 21b
The offset relationship between the axis of the holding member 22 and the tube holding hole 22b of the holding member 22 is determined by adjusting the rotation angle of the holding member 22.
22b is formed in such a manner that it can be adjusted from concentric with the flange 21a to eccentric as appropriate. Also, the flange 21
A reinforcing rib 21h is radially disposed on the back surface of the portion a between the upper end of the cylindrical portion 21b and the reinforcing rib 21h to strengthen the strength of the flange portion 21a.

Thus, by appropriately rotating the holding member 22, the degree of deviation of the axis between the tube holding hole 22b and the flange portion 21a can be adjusted from a zero state to an appropriate deviation state. The flange 21a can be arranged concentrically with the pipe hole 11 by adjusting the rotation angle of the holding member 22 in accordance with the degree of deviation of the axis of both the pipe hole 11 and the pipe 15 in FIG. Therefore, the gap filling operation with the repair material 17 can be reliably performed, and the pipe hole 11 and the pipe
Even if the degree of misalignment between the two axes is various, if the pipe diameter is the same, all can be dealt with by one product. Then, the holding member 22 can be replaced with a tube holding hole 22b having a different diameter according to the tube diameter with respect to the holding hole 21c of the cylindrical portion 21b of the mounting member 21, so that the tube diameter differs. Even at the site, it can be dealt with by replacing the holding member 22 with the diameter of the tube holding hole 22b according to the diameter of the tube. Therefore, it is possible to handle almost all sites simply by preparing the mounting member 21 and several types of holding members 22 having different diameters of the tube holding holes 22b. Also, the left and right flange portions of the mounting member 21 holding the left and right holding portions 22a.
The 21a and the left and right cylindrical portions 21b1 can be opened and closed with the hinge 21d as a fulcrum, and the open and closed states can be performed by a one-touch operation of engaging and disengaging the stopper 21e with the to-be-stopped portion 21f. Is easy, and the gap filling workability can be improved.

FIG. 16 illustrates another embodiment of the receiving frame 12, and since the configuration is basically the same as that of FIG. 12, the description of the common configuration is omitted. The different configuration will be described. The left and right tubular portions 21b1 of the tubular portion 21b of the mounting member 21 have their other adjacent edges connected by hinges 21d, and the hinges 21d are used as fulcrums to form flange portions.
The left and right semi-circular ring-shaped flange portions 21a1 and the left and right cylindrical portions 21b1 in 21a are formed so as to be openable and closable. Also, on one side edge of the left and right cylindrical portions 21b1, one cylindrical portion 21b1 is provided.
On the other side and the stopper 21f on the other cylindrical portion 21b1.
Are respectively arranged, and this stopper 21e is
By locking to the flange 21f, the flange portion 21a and the cylindrical portion 21b can be locked in a closed state, and the locked state can be released by removing the stopper 21e from the stopped portion 21f and opening it. This has the same effect as that of FIG. 12, and furthermore, since the mounting member 21 is configured such that the portion of the flange portion 21a where the radial width is the smallest is open, the interval between the piping hole and the wall is narrow, In addition, the pipe is close to the hole surface on the wall side, so that it is possible to cope with a situation where the deviation between the pipe hole axis and the pipe axis is large, and the pipe can be easily attached and detached.

FIG. 17 illustrates another embodiment of the receiving frame 12, and since the configuration is basically the same as that of FIG. 12, the description of the common configuration is omitted. The different configuration will be described. The guide groove 21g in the holding hole 21c of the cylindrical portion 21b has a dovetail shape, and the convex portion of the holding member 22
Reference numerals 22d denote ant navels, respectively, and the holding member 22 is turned around the axis with respect to the mounting member 21 so as to be detachable. This has the same effect as that of FIGS. 12 and 16, and can be opened and closed while holding the left and right holding portions 22a on the left and right cylinder portions 21b1, respectively, and can be attached to and detached from the pipe.
