Abstract

PROBLEM TO BE SOLVED: To effectively conduct pipe fixing work in a plant or in a ship. SOLUTION: A pressing rod 20 is bent in a U shape larger than a diameter of a pipe 1, and male screw parts 2 are formed on both ends. A fastening nut 5 to which a fitting member 4 is rotatably attached is screwed onto the male screw parts 2. This pipe attaching U bolt 10 thus prepared is put over the pipe 1 and the fastening nuts 5 are fastened. Thus, the pipe 1 is fixed on an attaching member 6 such as a horizontal member or an angle.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pipe mounting U bolt used for fixing a pipe to a wall surface, a mounting member such as an angle member in plant construction or the like.

[0002]

2. Description of the Related Art Conventionally, as shown in FIG. 6, when a pipe 11 is mounted on a pipe mounting member 12 such as an angle member, a U bolt 13 formed in a U shape is hooked on the pipe 11 to mount the pipe mounting member 12. The tightening nut 15 is screwed and fixed to the tip of the threaded screw portion.

[0003]

In such a conventional pipe mounting method, when the pipe mounting member 12 such as a cross member or an angle member is arranged close to the wall surface, it is fastened to the tip of the U bolt 13. It is difficult to attach and tighten the nut 15.

[0004]

Therefore, in the present invention, the holding rod 20 is bent in a U-shape wider than the diameter of the pipe 1 to form male screw portions 2 and 2 at both ends, and the locking member 4 is rotated. The pipe 1 is mounted with a U-bolt 10 for pipe mounting in which the tightening nut 5 mounted in a possible state is screwed into the male screw portions 2 and 2, and the tightening nut 5 is tightened to attach the pipe 1 to an angle member or the like 6. I attached it to.

When the pipe 1 is directly attached to a metal wall surface without a mounting member 6 such as a horizontal member or an angle member, a locking member 4 is used.
The U-bolt 10 for pipe mounting can be used by forming a member (4a) that abuts against a metal surface and is welded.

When the pipe is attached to the attachment member 6 such as an angle member, the locking member 4 is hooked members (4b) and (4c) adapted to be hooked on the end of the pipe attachment member 6. This pipe mounting U bolt 10 can be used.

[0007]

According to the present invention, since the locking member 4 is welded or hooked to the mounting member 6 such as an angle to tighten the tightening nut 5, the pipe is mounted.
It is not necessary to temporarily fix the arrangement position of 1 to make a hole for penetrating the U bolt, and to insert the tightening nut 15 into the rear surface of the mounting member 6 and attach it to the male screw part of the U bolt 13 to tighten it. Is eliminated, and pipe work can be performed efficiently.

Further, in the case where the locking member 4 is a member 4a that abuts on a metal surface and is welded, the pipe can be directly fixed to a metal wall surface which could not be conventionally mounted, and the piping structure is simplified and manufactured. It also has the effect of reducing costs.

[0009]

1 and 2 show a first embodiment of the present invention, in which a pipe 1 is placed on an angle member 6 and temporarily positioned, and then a holding rod 20 is put on the pipe 1 to engage a locking member 4a at the tip thereof.
Are welded to the angle member 6.

The holding rod 20 is made of a rod material and is bent in a U-shape slightly wider than the diameter of the pipe 1, and the central portion is curved so as to follow the outer shape of the pipe 1. Further, male screw portions 2 and 2 are formed at both ends, and a locking nut 7 and a tightening nut 5 are screwed in. Insert the small diameter portion 3 of the mounting member 4a to be welded to the angle member 6 into the end of the tightening nut 5,
Tightening nut 5 so that the small diameter part 3 can rotate and does not come off.
The outer circumference of is pressed and narrowed down.

3 and 4 show another embodiment of the present invention. In FIG. 3, the mounting member 4b is lengthened so as to be hooked on the vertical piece of the angle member 6 and the tip is bent in an L shape. In FIG. 4, the mounting member 4c is shortened so as to be hooked on the thick portion of the angle member 6, and the tip is also bent in an L shape. FIG. 5 shows still another embodiment of the present invention, in which the pressing rod 20 is made of a band iron, and threaded rods to be the male screw portions 2 and 2 are welded to both ends.

According to the present invention, as described above, the mounting members 4a, 4
Since b and 4c are welded or hooked to the pipe mounting member 6, the pipe 1 can be fixed immediately after determining the disposition position, and there is no need for the conventional drilling process for the pipe mounting member 6. The work efficiency of piping work is improved.

Further, if a welding member such as the mounting member 4a is used, it is not necessary to bother to provide the angle member 6 for piping during the shipboard construction, and the pipe 1 is directly mounted on the wall surface by the U-bolt 10 for mounting the pipe of the present invention.
