The screw shaft 14 and a fastening nut 15 screwed onto the screw shaft 14 are arranged, and the screw shaft 14 is clamped at the tip of the holding member 12 with a steel pipe or the like sandwiched between the base member 10 and the holding member 12. The steel pipe or the like is held and fixed between the base member 10 and the pressing member 12 by being fitted to the portion 12a and pressing the pressing member 12 toward the base member 10 with the nut 15.
[0012]
Reference numeral 16 denotes a prismatic rod-like body having a rectangular cross section for connecting the U-shaped clamp 1 and the pipe clamp 2, the thickness of the short side is slightly smaller than the width of the through hole 9, and the outer end has a square axis The corner portion 17 is formed integrally with the screw shaft portion 18 that protrudes from the angular shaft portion 17, and further has a through-hole 9 of the U-shaped main body 6 on both side surfaces on the long side near the outer end. A retaining pin 19 that protrudes close to the inner side surface (inner side surface of the bent portion 8) is provided. The pin 19 constitutes a retaining portion. The pin 19 can be composed of both ends of a single pin that is press-fitted and fixed in the through hole of the rod-like body 16. Further, when the screw shaft portion 18 is constituted by another screw shaft inserted into the rod-shaped body 16, the screw 19 and the rod-shaped body 16 can be coupled by the pin 19.
[0013]
The rod-like body 16 is inserted into the through-hole 9 from the inside of the U-shaped main body 6, and the angular shaft portion 17 and the screw shaft portion 18 project outward from the through-hole 9. The fixed seat 21 provided with the hole 20 is fitted so as not to rotate using the square hole 20, and the through hole 22 provided in the base member 10 of the pipe clamp 2 is used outside the fixed seat 21. The pipe clamp 2 is fitted to the square shaft portion 17, and the nut 23 is screwed and fastened to the screw shaft portion 18 protruding from the through hole 22. Thus, the fastening of the nut 23 is limited by the angular shaft portion 17, and the base member 10 of the pipe clamp 2 is not fixed to the rod-like body 16 even if the nut 23 is completely fastened and fixed by caulking or the like. Instead, the pipe clamp 2 can freely rotate around the axial center of the rod-shaped body 16 (the axial center of the screw shaft portion 18).
[0014]
The pipe clamp 2 can be fixed to a fixed seat 21 that cannot rotate with respect to the rod-shaped body 16 by a fixing tool 24. The fixing seat 21 is made of a substantially rectangular plate material with four corners cut off, and the fixing tool 24 is selectively press-separated from the positioning peripheral surfaces 21a to 21d on the four sides around the fixing seat 21 1 It is comprised from the bolt 25 of a book.

A part of the tip of the bolt 25 that protrudes toward the fixed seat 21 from the plate projection 28a of the bolt 25 is loosely fitted in the through hole 27. ing.
[0015]
The pipe clamp mounting apparatus having the above configuration can be used as follows. That is, when the U-shaped clamp 1 is fitted to a flange portion such as a steel frame, the pipe clamp 2 is placed on the outer side of the side wall portion 3 of the U-shaped clamp 1 so that the pipe clamp 2 is placed on the side wall portion 3 of the U-shaped main body 5. The rod-shaped body 16 is rotated toward the side wall portion 3 together with the rod-shaped body 16 around the corner portion between the connecting wall portion 5 and the rod-shaped body 16 is fitted into the inner recess 5 a of the projecting portion 8 in the coupling wall portion 5. In this state, the U-shaped main body 5 is fitted into a flange portion such as a steel frame and the fastening screw shaft 7 is screwed, and the tip disc spring 7a of the fastening screw shaft 7 and the side wall of the U-shaped main body 5 are combined. The flange portion is sandwiched and fixed with the portion 3.
[0016]
As a result, the rod-like body 16 is sandwiched between the bottom surface of the inner recess 5a of the projecting portion 8 in the connecting wall portion 5 of the U-shaped main body 5 and the end surface of the flange portion such as a steel frame. , It is fixed to the U-shaped clamp 1. Of course, at this time, the end surface of the flange portion such as a steel frame is also in contact with or close to the inner surface of the connecting wall portion 5 (the inner surfaces of the left and right projecting portions of the projecting portion 8). By holding and fixing the steel pipe or the like to the pipe clamp 2 in such a state, the steel pipe or the like can be supported on the upper side or the lower side of the flange portion such as a steel frame.
[0017]
As shown by phantom lines in FIG. 1A, before fitting and fixing the U-shaped clamp 1 to a flange portion such as a steel frame, the pipe clamp 2 is connected to the corner between the side wall 3 and the connecting wall 5 of the U-shaped main body 5. The rod-shaped body 16 is rotated 90 degrees toward the connecting wall portion 5 together with the rod-shaped body 16, and the rod-shaped body 16 is fitted into the inner recess 3 a of the curved portion 8 in the side wall portion 3. By fitting the shape clamp 1 to a flange portion such as a steel frame and fixing it with the fastening screw shaft 7, the rod-like body 16 is formed in the inner recess 3 a of the bent portion 8 in the side wall portion 3 of the U-shaped main body 5. It is fixed to the U-shaped clamp 1 in the second posture B that is sandwiched between the bottom surface and the side surface of the flange portion such as a steel frame. Of course, also at this time, the side surface of the flange portion such as a steel frame is in contact with or close to the inner side surface of the side wall portion 3 (the inner side surface of the left and right projecting portions of the bent portion 8). By holding and fixing the steel pipe or the like to the pipe clamp 2 in such a state, the steel pipe or the like can be supported outside the flange portion such as a steel frame.
[0018]
As described above, the pipe clamp 2 can be fixed to the U-shaped clamp 1 in either the first posture A or the second posture B, and is further held and fixed by the pipe clamp 2. When it is desired to change the direction of the steel pipe or the like, the bolt 25 is loosened and retracted to a position where the tip of the bolt 25 and the peripheral surface of the fixed seat 21 do not buffer when the pipe clamp 2 rotates, and the pipe clamp 2 is moved into a rod-like body in such a state. The direction of the pipe clamp 2 is rotated around the 16 screw shaft portions 18, and the orientation of the pipe clamp 2 can be set to a desired direction out of four directions that can be set in units of 90 degrees by the positioning peripheral surfaces 21 a to 21 d around the fixed seat 21. If this is the case, the bolt 25 is screwed in that state, the tip of the bolt is pressed against one of the positioning peripheral surfaces 21 a to 21 d of the fixing seat 21, and the pipe clamp 2 is fixed to the rod-shaped body 16. There.
[0019]
The screw hole 26 of the bolt 25 can be provided in a protruding piece obtained by cutting and raising a part of the base member 10 of the pipe clamp 2 without using another plate material 28 as in the above embodiment. A nut can be simply attached to the outer surface of the base member 10 by welding or the like.
[0020]
Further, the fixing tool is not limited to the bolt 25 that can be directly pressed and separated from the positioning peripheral surfaces 21a to 21d of the fixing seat 21 as in the fixing tool 24 of the above embodiment. For example, as shown in FIG. 3, a through screw hole 29 is provided in the base member 10 of the pipe clamp 2 in a direction substantially orthogonal to the length direction of the rod-like body 16, and the through screw hole 29 is threaded through and A bolt 30 that can be operated on the outside of the pipe clamp 2, and an L-shaped press that is fitted and supported by the bolt 30 so as to be relatively rotatable so that the distal end portion 30 a can be pressed against and separated from the positioning peripheral surfaces 21 a to 21 d of the fixed seat 21. A fixture 32 can also be constructed from the plate 31. In this fixing tool 32, the tip 30 a of the pressing plate 31 is pressed against the positioning peripheral surfaces 21 a to 21 d of the fixing seat 21 by the screw 30 and the pipe clamp 2 is fixed to the rod-shaped body 16. By relaxing and retreating, when the pipe clamp 2 is rotated, the pressing plate 31 is pushed out between the positioning peripheral surfaces 21 a to 21 d of the fixed seat 21 to allow the pipe clamp 2 to rotate. . However, as shown in the figure, it is desirable to interpose an elastic material, such as a compression coil spring 33, between the base member 10 and the pressing plate 31 so that the pressing plate 31 is always pressed against the head 30a of the bolt 30. Even in the fixture 32, the through screw hole 29 is not directly formed in the base member 10 but can be formed by using other members in combination.
[0021]
Further, the number of circumferential surfaces 21a of the positioning peripheral surface 21a formed around the fixed seat 21, that is, the number of angles at which the pipe clamp rotating around the longitudinal axis of the rod-shaped body 16 can be fixed is as follows. Of course, it is not limited to four every 90 degrees of the above embodiment, and may be less or more.
[0022]
