Description

[Detailed description of the invention] [Field of industrial application] The present invention relates to a fixing device for a pipe support, and more specifically, a fixing device for fixing a support band and a pipe holding part having a heat insulating effect or a vibration damping effect. Regarding ingredients.

[Prior art] Conventionally, as a technique for fixing a support band and a pipe holding part, Japanese Utility Model Application No. 56-962, No. 56-963, and No. 56
−15882, No. 56-15883, No. 61-97677, No.
Those described in No. 61-135078 and Japanese Patent Publication No. 56-35799 are known.

[Problems that the invention attempts to solve] Utility Model Application No. 56-962, No. 56-963, No. 56-15882
No. 56-15883 discloses a technique for fitting and fixing a support band into a groove formed on the outer peripheral surface of a pipe holding portion.

Moreover, in Utility Model Application No. 61-97677, a convex part or a concave groove is formed on the outer circumferential surface of the pipe holding part, and a concave part or convex part corresponding to the convex part or concave part is formed in the support band to fit it. A technique for doing so has been disclosed.

However, with these techniques, the support band and the pipe holding part can be sufficiently fixed after the piping work is completed, but during the work, that is, during installation, the support band and the pipe holding part are only fitted together, so the work is difficult. Considering that this is done in very busy places such as construction sites and other construction sites, fitting alone is not sufficient fixation, and when attaching to the pipe, it is necessary to hold down both the support band and the pipe holding piece. The disadvantage is that you have to work while

Furthermore, Japanese Utility Model Application No. 135078/1988 discloses a technique for bonding a support band and a pipe holding part.

However, in this technique, adhesive is applied to the inner circumferential surface of the support band and/or the outer circumferential surface of the pipe holding part,
Appropriate adhesion must be carried out, and this process has the disadvantage of being very labor intensive, considering the number of support bands and pipe holding pieces used in the piping equipment, and the application process cannot be carried out on site. When this is done, dust and the like adhere to the adhesive surface, resulting in a decrease in adhesive strength, that is, insufficient fixation.

Furthermore, Japanese Patent Application Laid-Open No. 56-35799 discloses a technique in which an adhesive tape is laminated on the outer peripheral surface of a pipe holding portion and adhesively fixed to a support band.

However, this technique has the drawback that since piping work is generally performed in very crowded places with a lot of dust, etc., dust and the like adhere to the adhesive surface of the adhesive tape, resulting in a decrease in adhesive strength, that is, insufficient fixing force. Also, if you remove the pipe holding piece from the support band for some reason such as changing the pipe position during gluing work,
If the adhesive strength is strong, it takes time to remove the adhesive, and furthermore, when the adhesive is used again, the adhesive strength decreases compared to the first time.

[Purpose of the invention] Therefore, the purpose of the invention is to securely fix the support band and the pipe holding part, and to make it easy to install and remove.
Furthermore, it is an object of the present invention to provide a fixture for a pipe support that can be used repeatedly.

[Means for Solving the Problems] In order to achieve the above object, the inventor of the present invention has made extensive studies and has arrived at the present invention.

That is, the fixture for the piping support according to the present invention is
A fixture for a pipe support such as a heat insulator, which has a pipe holding part formed by placing two pipe holding pieces having semicircular holes face-to-face, and a pipe support band provided around the outer periphery of the holding part. The fixing device is composed of a main body having a length substantially equal to the width of the outer circumferential surface of the holding part, and clamping parts formed at both ends of the main body and capable of pinching the side surfaces of the holding part. It is characterized by

[Function] According to the present invention, there is provided a fixture main body having a length approximately equal to the width of the outer peripheral surface of the pipe holding part, and a clamping part formed at both ends of the main body and capable of pinching the side surfaces of the holding part. Since the main body presses the support band and the clamping part clamps the side surface of the pipe clamping part, the pipe clamping part can be securely fixed to the support band, and can be fixed only by clamping. Therefore, it is easy to install and remove, and it can be used repeatedly.

[Example] Hereinafter, an example of the present invention will be described based on the accompanying drawings.

FIG. 1 uses an example of the fixture according to the present invention,
A perspective view showing the support band with the pipe holding part fixed, Fig. 2 is a cross-sectional view taken along the line -, Fig. 3 is a side view showing another embodiment of the present invention, and Fig. 4 is a cross-sectional view of the same as above, Fig. 4 is a side view showing another embodiment of the invention. FIG. 7 is a perspective view showing another embodiment.

In the figure, 1 is a fixture main body, and 2 is a clamping part formed at both ends of the main body 1, preferably at a substantially right angle (slightly smaller than a right angle is more preferable).

The main body 1 has a flat plate shape with a length approximately equal to the width of the outer peripheral surface of the pipe holding part 11 formed by placing two pipe holding pieces 11A and 11B having semicircular holes face-to-face. The invention is not limited to this, but by forming a curved surface that matches the curved surface of the outer circumferential surface, the contact area of the pipe holding portion 11 and the support band 10 with the outer circumferential surface can be increased, and the rigidity can be increased.

In addition, as shown in the figure, the support band 10 is attached to the pipe holding part 1.
is fitted into a groove 11' formed on the outer peripheral surface of 1,
The outer peripheral surface of the pipe holding part 11 and the pipe support band 1
If the outer circumferential surface of 0 is flat (so-called flush), a flat (and curved) fixing device as shown in FIG. You can also do it.

For example, a concave groove 11' is formed on the outer peripheral surface of the pipe holding piece 11.
is not formed, a convex portion 4 corresponding to the cross section of the support band 10 is formed on the main body 1 (a third
(see figure).

Further, as in Utility Model Application Publication No. 61-97677 cited in the prior art, a convex portion or a concave groove (so-called string extension portion) is formed on the outer peripheral surface of the pipe holding portion 11, and a concave portion corresponding to the convex portion or concave groove is formed. Alternatively, in the case where a convex portion is formed on the piping support band 10 and fitted, it is preferable to form convexes and convexities on the main body 1 to correspond to the convexes and convexities, since the outer circumferential surface will have concavities and convexities. In these cases, in addition to being clamped by the clamping part, it is also fixed by fitting.
This will provide a stronger fixation.

Furthermore, as shown in FIGS. 1 to 3, the clamping portion 2
By forming the hook part 3 on the
It is possible to increase the fixing force by hooking and locking. The shape of the hook portion 3 may be cut and raised inward as shown in the figure, but is not particularly limited, and may be formed in any shape as long as it can be hooked onto the side surface of the pipe holding portion 11. You can.
For example, as shown in FIG. 4, cutout portions 2A may be formed at both lower ends of the clamping portion 2, and hook portions 3 may be formed above the cutout portions 2A. In this case, it is preferable to bend both the clamping parts 2, 2 to opposite sides, and also to bend each clamping part 2 inward. Since the tip of the hook part 3 is fixed so as to bite into the pipe holding part 11, stronger fixation is possible. Further, the shape of the hook portion 3 can be formed into various shapes such as one or more hemispherical protrusions.

In the present invention, when the hook part 3 is provided,
Only the hooking part 3 may have a clamping function, and in that case, the clamping part 2 does not need to clamp the pipe holding part 11.

The material of the fixture in this embodiment may be any material as long as it has sufficient strength to clamp and fix the pipe holding part 11 to the pipe support band 10, such as metal (suitable for bending). or plastic (suitable for integral molding).

Furthermore, when performing piping work using the fixing device of the present invention, the fixing device is most needed during the work, so it is possible to leave the fixing device attached after the work is completed, but it can be removed. It is also possible to reuse it for other piping work.

[Effects of the invention] According to the invention, it is possible to provide a fixture for a pipe support that can securely fix a pipe holding part to a pipe support band, is easy to install and remove, and can be used repeatedly. I can do it.
