[Detailed description of the device]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pipe support, and more particularly to improvement of a pipe support used when a large-diameter pipe is supported by a frame and fixedly held.

[Prior art]

Conventionally, when piping a large diameter pipe of 250A to 800A,
The H-shaped steel frame is used to support the pipe, and the U-bolt is wound around and fixed to the outer peripheral surface of the pipe. The saddle is bitten in the gap between the pipe and the frame so that the pipe can be held stably.
An example of such a conventional pipe support structure is shown in FIGS. The frame is assembled by an H-shaped steel 1, and a pipe 2 is supported on the upper surface of the H-shaped steel 1 which constitutes the beam portion of the frame. Wedge-shaped saddles 3 are inserted from both sides into a gap formed between the pipe 2 and the surface of the H-shaped steel 1 so as to prevent the pipe 2 from rolling and hold the position. . A U bolt 4 is wound around the outer peripheral surface of the pipe 2, and the end of the U bolt 4 penetrates the flange of the H-shaped steel 1 and is tightened by a nut 5 to fix the pipe 2. Normally, the U bolts 4 are double-threaded and are tightened at symmetrical positions with the web of the H-section steel 1 sandwiched therebetween.

[Problems to be solved by the device]

However, in the conventional support structure, since the U-bolt 4 and the saddle 3 are separate bodies, they must be set individually, and there is a drawback that the installation work is complicated.
Recently, instead of H-shaped steel, rectangular steel pipes have come to be widely used as a frame structure from the viewpoint of dust resistance,
The conventional support structure has a problem that the pipe cannot be properly supported. That is, since the H-section steel has a large surface area and also has a concave portion, it has a shape in which dust is likely to adhere, and radioactive contamination dust is easily accumulated particularly in equipment that handles radioactive substances. For this reason, square steel pipes have come to be used as a frame material in which pollutant dust does not easily accumulate. However, when this rectangular steel pipe is used for a frame, it is difficult to attach and fix the saddle and the U-bolt, and in some cases, a method of fixing a through hole to the rectangular steel pipe is used. Focusing on the above-mentioned conventional problems, the present invention can be easily attached to a frame composed of square steel pipes, and has a saddle action and a U-bolt fixing action in combination for easy handling. The purpose is to provide plumbing support.

[Means for Solving the Problems]

In order to achieve the above object, a pipe support according to the present invention is a pipe support for fixing and holding a pipe supported by a frame constructed by a rectangular steel pipe together with a U bolt, and is placed on the rectangular steel pipe. It has a pair of pipe fixing seats arranged on both side surfaces of the pipe. The pipe fixing seat is formed by bending a plate material into an inverted U shape, and a stopper plate is provided at an intermediate depth position in the groove to set the inside. It has a two-layer structure, the opening side having the stopper plate as the bottom is a fitting seat fitted to one surface of the square steel pipe, and the plate portion above the stopper plate is provided with a bolt through hole for the U bolt. The seat is a U-bolt mounting seat, and a saddle portion is formed in a notch at a portion of the pipe fixing seat facing the pipe side wall.

[Action]

According to the above configuration, the fitting seat portion may be attached to the pipe bearing surface of the rectangular steel pipe, and this may be positioned and welded to the rectangular steel pipe. At this time, since the saddle portion is formed at the portion facing the side surface of the pipe, the saddle portion is brought into contact with the side surface of the pipe during positioning to prevent rolling. Further, since the U-bolt mounting seat is provided so as to be separated from the fitting seat portion and maintain an appropriate height with respect to the surface of the rectangular steel pipe, the U-bolt can be fixed without interfering with the rectangular steel pipe. . Therefore, the saddle function and the U-bolt fixing function are performed with one piping support, which facilitates the installation work and
This eliminates the need for defective processing such as drilling in rectangular steel pipes.

【Example】

Hereinafter, a specific embodiment of the piping support according to the present invention will be described in detail with reference to the drawings. 1 and 2 show a front view and a side view of the assembled state of the pipe support according to the embodiment. The large-diameter pipe 12 supports the rectangular steel pipe 10 that constitutes the beam part of the frame.
The pipe fixing seats 14 are respectively attached to the square steel pipes 10 located at the lower portions of both sides of the pipe. The pipe fixing seat 14 is formed by bending an iron plate into an inverted U shape to form an opening in one side, and the opening width is set to a size in which the square steel 10 can be fitted. A stopper plate 16 is integrally provided at an intermediate depth position of the pipe fixing seat 14 to form a two-layer structure inside, and a concave portion is formed on the opening side partitioned by the stopper plate 16 to a square steel pipe 10 and a seat portion 18 is formed. I am trying.
Therefore, the pipe fixing seat 14 is held by the square steel pipe 10 by contacting the stopper plate 16 with the surface of the square steel pipe 10 by mounting the fitting seat portion 18 with the opening side facing the pipe bearing surface of the square steel pipe 10. On the other hand, the bottom plate portion of the pipe fixing seat 14 which is located at a constant distance from the stopper plate 16 is set at a constant height from the pipe bearing surface of the square steel pipe 10. The mounting seat is 22. That is, the mounting seat 22 is set to a height with a space defined by the mounting position of the stopper plate 16 from the rectangular steel pipe 10. A bolt through hole (not shown) for penetrating the tip of the U bolt 20 is bored in the mounting seat 22 as described above, and
The end of U-bolt 20 is tightened by 24 and fixed. In this embodiment, two bolt through holes are provided,
Two U bolts 20 are hung around the outer circumference of the large diameter pipe 12. Further, the pipe fixing seats 14 are arranged on both sides of the large diameter pipe 12, respectively.
A curved saddle portion 26 that follows the circular arc of the large-diameter pipe 12 is cut out at the upper corner edge on the side facing the. Therefore, the pipe fixing seat 14 has a wedge action by pressing the saddle portion 26 so as to approach the large diameter pipe 12 in a state where the fitting seat portion 18 is fitted in the rectangular steel pipe 10. The saddle portion 26 is formed in an arc shape, but it may be a notched structure that is linearly inclined.
In this case, it is possible to adapt to the outer diameter size of various large diameter tubes 12. The pipe fixing seats 14 configured as described above are arranged so as to be located on both sides of the large diameter pipe 12, and the fitting seat portions 18 are fitted and attached to the pipe bearing surfaces of the rectangular steel pipe 10. Then, the gap between the large diameter pipe 12 and the U bolt 20 is adjusted, and then fixed to the square steel pipe 10 by welding. In this way, the pair of pipe fixing seats 14 are attached to the square steel pipe 10, and the large diameter pipe 12 to be piped is installed so as to contact the saddle portion 26 of the pipe fixing seat 14. After that, the U-bolt 20 is hung around the outer circumference of the pipe, the tip of the U-bolt 20 is passed through the mounting seat 22 of the pipe fixing seat 14, and the nut 24 is tightened to complete the installation. According to such an embodiment, when the supporting frame of the pipe is constituted by the square steel pipe 10, the mounting seat 22 of the U bolt 20 is provided at a constant height apart from the surface of the square steel pipe 10. , Square steel pipe 10 does not need to be processed, and U
The length of the bolt 20 need only be short. Since the fitting seat portion 18 is fitted and held on the rectangular steel pipe 10, stable positioning can be achieved. Further, since the pipe fixing seat 14 is provided with the saddle portion 26, it is not necessary to use the saddle as a separate component. This simplifies the support work and improves workability. In the above embodiment, the case where two U bolts 20 are hung is shown, but as shown in FIG. 3, it is also possible to hang one U bolt 20 to fix and hold the large diameter pipe 12.
