Abstract

PURPOSE:To ensure adhesion between a pipe clamp and a pipe and to prevent the damage of the outer surface of the pipe by providing a spring part which is protruded to the inner side of a curved part and stretched along the curved part. CONSTITUTION:A pipe clamp 10 made of a steel sheet comprises a cylindrical curved part 12; and a pair of plate-form mounting parts 14 connected to the curved part. Spring parts 18 protruded toward the inside and stretched along the curved surface of the curved part 12 are formed on the curved part 12. By fastening the mounting parts 14 against a pipe support S by a bolt B and a nut N during use, the diameter of the curved part 12 is reduced, a pipe P inserted at the inner side of the curved part 12 is fastened and fixed to the pipe support S. The spring part 18 is resiliently deformed along with fastening and an energizing force to press the pipe P is exerted. This constitution ensures adhesion between the pipe clamp 10 and the pipe P. Further, an excessive force is prevented from being exerted on the outer surface of the pipe P through resilient deformation of the spring part 18, and the outer surface of the pipe P is prevented from being damaged.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pipe clamp for holding a tubular object such as a steel pipe or a columnar object such as a round bar inside a curved portion.

[0002]

2. Description of the Related Art As illustrated in FIG. 8, a pipe clamp 102 holds a pipe 106 or the like at a curved portion 104 and is attached to an apparatus, a structure or the like via a bolt or the like inserted through a screw hole 108. In the conventional pipe clamp 102, the adhesion with the pipe 106 and the like is improved, and the pipe 10
A cushioning material 110 made of rubber or the like was provided on the inner surface of the curved portion 104 for the purpose of protecting the outer surface of 6 or the like and absorbing vibration.

[0003]

However, with such a structure, the manufacturing process is complicated, for example, the process of adhering two kinds of materials, that is, a steel body and a rubber cushioning material is indispensable. there were.

[0004]

Means for Solving the Problems As a means for solving the above problems, a pipe clamp of the present invention is a pipe clamp for holding a tubular or columnar object inside a curved portion, and the pipe clamp projects inside the curved portion. In addition, a spring portion extending along the curved portion is provided.

[0005]

In the pipe clamp having the above structure, for example, the pipe is clamped and held by the curved portion. At this time, the spring portion comes into contact with the outer surface of the pipe, but the spring portion elastically deforms with tightening, and exerts an urging force for pressing the outer surface of the pipe toward the center. This ensures the close contact between the pipe clamp and the pipe. Further, since the spring portion is elastically deformed, it is possible to prevent an excessive force from acting on the outer surface of the pipe, so that the outer surface of the pipe is not damaged. Moreover, when vibration is applied to the pipe, the spring portion acts as a cushioning material that absorbs this vibration, and the vibration of the pipe is damped.

It is not necessary to provide a cushioning material such as rubber on the pipe clamp, and the manufacturing process of the pipe clamp is simplified.

[0007]

Next, embodiments of the present invention will be described. As shown in FIGS. 1 and 2, the steel plate pipe clamp 10 is
It is provided with a tubular curved portion 12 and a pair of flat plate-shaped mounting portions 14 connected to the curved portion 12. 1 for each mounting part 14
A screw hole 16 is formed at a location.

On the other hand, the bending portion 12 is provided with seven spring portions 18 projecting inward of the bending portion 12 and extending substantially along the curved surface of the bending portion 12. As shown in FIG. 2 and FIG. 3 which is a development view of the bending portion 12, the spring portion 18
Has a strip shape, and one end thereof is connected to the curved portion 12. Further, as shown in FIG. 1A, the other end of the spring portion 18 is separated from the bending portion 12. Therefore, the spring portion 18 is elastically deformable in the swinging direction indicated by the arrow A with the end portion connected to the bending portion 12 as a fulcrum. These spring portions 18 are formed by punching in a direction from the outside to the inside of the curved portion 12 by press working.

When the pipe clamp 10 is not in use, as shown in FIG. 1 (a) and FIG.
4 and 14 are separated from each other. At the time of use, as shown in FIG. 1 (b), the mounting portion 14 is attached to the pipe support S such as a bracket through the bolt B and the nut N.
By reducing the diameter of the curved portion 12 by tightening
The pipe P inserted inside the bending portion 12 is tightened.
As a result, the pipe P is held by the pipe clamp 10 and fixed to the pipe support S.

At this time, the tightening force by the bending portion 12 is
It acts on the pipe P via the spring portion 18. The spring portion 18 elastically deforms with tightening, and exerts an urging force that presses the outer surface of the pipe P toward the center. This ensures the close contact between the pipe clamp 10 and the pipe P. Further, since the spring portion 18 is elastically deformed, an excessive force is prevented from acting on the outer surface of the pipe P, so that the outer surface of the pipe P is not damaged. Moreover, when the pipe P is vibrated, the spring portion 18
Acts as a cushioning material that absorbs this vibration, and the vibration of the pipe P is damped.

Since it is not necessary to bond a cushioning material such as rubber to the inside of the curved portion 12, the pipe clamp 10 is made of only one steel plate, and the spring portion 18 by press punching is used as a process. And the bending process for forming the curved portion 12 and the mounting portion 14.
Therefore, the manufacturing process of the pipe clamp 10 is extremely simple. (Modifications) Next, various modifications will be described.

FIG. 4 shows an example of the arrangement of the spring portions. The spring portions 28 are arranged in a staggered manner as shown in FIG. 4 (a) and the spring portions 38 are provided as shown in FIG. 4 (b). Various arrangements are possible, such as arranging in three rows. Further, in the above example, one end of the spring portion is a fixed end fixed to the curved portion and the other end is a free end. However, as shown in FIG. 5, both ends of the spring portion 48 are not separated from the curved portion 42. It can also be a fixed end. Even in this case, the spring portion 48 can be elastically deformed, and the same effect as that of the above-described example is exhibited.

Alternatively, as shown in FIG. 6, the spring portion 90
It is also possible to provide a convex strip 92 along the curved direction. With such ridges 92, the contact area between the spring portion 90 and the pipe or the like decreases, and the frictional force with the spring portion 90 (the ridges 92) increases accordingly. Can be held more reliably.

Further, the shape of the pipe clamp itself can be freely set according to the purpose of use. For example, as shown in FIG. 7, the bending portion 52 has a semicircular shape, and a mounting portion 54 is provided at one end side thereof to hold a pipe or the like by the elastic force of the bending portion 52 (FIG. 7A). A pipe clamp 60 (FIG. 7 (b)) having a structure in which the mounting portion 64a extends in the tangential direction of the cylindrical curved portion 62 and the other mounting portion 64b extends in a direction matching with the mounting portion 64b, which corresponds to two types of pipes, large and small. Bendable part 72 that can be formed and mounting part 7 similar to FIG.
Pipe clamp 70 (FIG.
(C)) The pipe clamp 80 (FIG. 7) in which the curved portion 82 has a rectangular shape and can hold a square pipe or the like and is provided with a mounting portion 84a extending in the side direction and a mounting portion 84b facing the mounting portion 84a.
Various shapes such as (d)) are possible. Of course, the shape shown in FIG. 8 as a conventional example is also possible.

As described above, according to the embodiment and its modification,
Although the present invention has been described, it is needless to say that the present invention is not limited to these examples and can be variously implemented without departing from the scope of the present invention. For example,
Although the pipe clamp is made of a steel plate in the above example, it may be made of high-strength plastic or the like.

[0016]

As described above, the pipe clamp of the present invention does not require a cushioning material made of rubber or the like for the purpose of improving the adhesion to the pipe or the like, protecting the outer surface of the pipe or absorbing vibration. Yes, the structure is simple and the manufacturing process is simple.
