Description

[Detailed description of the invention] [Purpose of the invention] (Field of industrial application) The invention is a method for attaching pipes such as plumbing pipes and electrical conduits to a mounting plate having a mounting hole or other appropriate member having a mounting hole. This invention relates to supporting metal fittings for fixedly supporting pipes, etc.

(Prior Art) Conventionally, this type of support fittings for pipes, etc., have been composed of a pair of split bodies 20 and fasteners such as bolts and nuts, as shown in FIG. The divided body 20 is tightened with fasteners such as bolts and nuts, and the pipe is tightened and fixedly supported by the divided body 20 (for example, the connecting band described in Japanese Utility Model Application Publication No. 50-154920) metal fittings, etc.) or the center portion of the strip-shaped sheet material is appropriately curved into an arc shape, and both end portions of this strip-shaped sheet material are welded, and protrusions are formed at both ends of the strip-shaped sheet material so as to include the welded portions, There are devices in which this protrusion is caulked to apply a tightening force to the inner hose (for example, a caulking-type hose clamp device described in Japanese Utility Model Application Publication No. 56-148178, etc.).

(Problems to be Solved by the Invention) However, the former type of support fittings that use fasteners such as bolts and nuts have the disadvantage that the installation work is troublesome and the work efficiency is low. Particularly, when work gloves are worn in consideration of the safety of the worker, the installation work becomes extremely troublesome. Furthermore, until the work of installing fasteners such as bolts and nuts is completed, the work must be carried out while supporting the pipe, split body, and fasteners such as bolts and nuts with one hand. When working at heights or in the dark,
There was a drawback that the danger of not being able to use both hands freely increased.

Also, in the latter case, which applies a tightening force to the inner hose by caulking the protrusion, it is possible to apply a tightening force to the hose, etc., but the hose, etc. can also be fixedly supported in the mounting hole of the mounting plate. There are disadvantages in that the structure is not properly arranged, and in addition, both ends of the strip sheet material must be welded together, and since the welded portion is included in the protrusion, it is difficult to caulk the protrusion, and when the protrusion is caulked. There was also a risk that the welded parts would be damaged.

[Structure of the idea]

(Means for Solving the Problems) Therefore, the present invention provides locking portions 2 at both ends of a holding portion 1 that holds a pipe P such as a plumbing pipe or an electric conduit.
In a support fitting such as a pipe that fixedly supports the pipe P by inserting and locking the locking part 2 into the mounting hole T1 of the mounting plate T, etc., approximately the center of the strip-shaped sheet material is A holding part 1 formed by curving in an arc shape, a locking part 2 formed by bending both ends of a strip-shaped sheet material so as to open outward, and a holding part 1 formed by bending the holding part 1 in the circumferential direction. A tightening part 3 which is bulged outward from both ends of a tightening space 4 having a partially discontinuous part is integrally connected, and a recess 5 is provided at the base end part of the tightening part 3. Due to plastic deformation of the clamping part 3, which narrows the clamping space 4, the holding part 1
By forming the locking portion 2 so that it can tighten the pipe P and also fixing the locking portion 2 to the mounting hole T1, the above-mentioned difficulties can be solved.

(Example) Hereinafter, the present invention will be explained with reference to illustrated examples.

In the figure, A indicates a pipe support fitting of the present invention, and this pipe support fitting A has a strip-shaped sheet material curved in an approximately central portion into an arc shape to form a holding portion 1 that can be brought into close contact with the outer periphery of the pipe P. A locking part 2 consisting of a pair of locking pieces 2a formed by bending both ends of a strip sheet material so as to open outward is connected to the holding part 1. It is constructed by providing a tightening space 4 that is partially discontinuous in the circumferential direction, and providing tightening portions 3 that are curved outward from both ends of this tightening space 4. That is,
Plastic deformation of the clamping part 3 such that the clamping space 4 becomes narrow allows the holding part 1 to clamp the pipe P and the locking part 2 to be fixed in the mounting hole T1. .

In addition, a depression 5 is formed in each of the proximal end portions of the tightening portion 3 connected to the holding portion 1 so that the tightening portion 3 can be easily held with a pinching tool H such as a clipper. . Incidentally, the number of tightening parts 3, the arrangement positions of the tightening parts 3 in the holding part 1, etc. are not limited to those shown in the illustrated example and can be set freely as appropriate.

The present invention is constructed as described above, and its use will be explained next. First, as shown in FIG. 2a), expand the locking part 2 to prevent the pipe support fitting A from falling off, and lock the locking pieces 2a to the edge of the mounting hole T1, respectively, and hold the pipe P with the holding part 1. Hold (temporarily held). Then, apply a clamping tool H such as a clipper to the recess 5 and tighten the tightening part 3,
When the clamping part 3 is plastically deformed so that the clamping space 4 becomes narrower, the length of the holding part 1 in the circumferential direction becomes shorter, and the holding part 1 tightens the outer peripheral surface of the pipe P.
When the tightening continues, each of the locking pieces 2a closes in the mounting hole T1.
It opens inside and strongly presses against the hole edge of the mounting hole T1,
Moreover, the pipe P is pressed against the surface of the mounting plate T and is fixed (see FIG. 3).

By the way, as shown in FIG. 4, the clamping space 4 of the clamping part 3 is formed into a substantially U-shape to prevent the pipe P from loosening due to expansion due to a strong unexpected external force. Alternatively, a loosening prevention device 10 may be attached to the recess 5 to firmly clamp the tightening portion 3.

Also, to prevent the fixed state of the pipe P from loosening,
A bolt insertion hole may be formed in the tightening portion 3, and the tightening portion 3 may be firmly clamped using a bolt or nut (not shown).

Furthermore, after the pipe support fitting A is attached, the tightening part 3 may be crushed toward the pipe P side.

[Effect of idea]

Therefore, pipes P such as plumbing pipes and electrical conduits
Two locking parts are connected to both ends of the holding part 1 that holds the
In a support fitting such as a pipe that fixedly supports the pipe P by inserting and locking the locking portion 2 into the mounting hole T1 portion of the mounting plate T, etc., the substantially central portion of the strip-shaped sheet material is curved into an arc shape. Holding part 1 to be formed
, a locking portion 2 formed by bending both end portions of a strip-shaped sheet material so as to open outward, and a tightening space 4 that is partially discontinuous in the circumferential direction of the holding portion 1.
A tightening part 3 which is bulged outward from both ends of the clamping part 3 is integrally arranged, and a recess 5 is formed at the base end of the tightening part 3 so that the tightening space 4 becomes narrow. Due to the plastic deformation of the tightening part 3, the holding part 1 can tighten the pipe P, and the locking part 2 can be tightened in the mounting hole T1.
Since it is formed so that it can be fixed to the holding part 1
tightens the pipe P, the locking part 2 opens in the mounting hole T1 and presses the hole edge of the mounting hole T1, and the pipe P
is pressed against the surface of the mounting plate T, etc., and a strong fixed support force can be obtained. In addition, the pipe support fitting A and the pipe P may be damaged by external force in the mounting hole T1.
The pipe P can be fixed and supported in a predetermined position reliably and easily without easily falling off from the part. Furthermore, the installation work of the pipe support fitting A is easy, and the work efficiency is also improved.

In particular, while holding the pipe P with the holding part 1, the locking part 2 is locked to the hole edge of the mounting hole T1 of the mounting plate T, etc.
It can be temporarily fixed to prevent it from falling off.
Both hands can be used freely to perform the next task or preparation for the next task by temporarily removing the hand from the work area, improving work efficiency and helping to further improve work efficiency. Furthermore, work at heights and in dark places can be performed safely and easily. Furthermore,
Even if work gloves are worn in consideration of worker safety, the attachment work can be performed very easily.

Further, the amount of plastic deformation of the tightening portion 3 can be easily adjusted and the deformation range can be set widely, and the range of application of the pipe P that can be attached to the pipe support fitting A is wide, making it very economical.

Furthermore, the structure of the pipe support fitting A itself is simple, has excellent robustness and durability, and is suitable for mass production and can be provided at low cost.

Since the recesses 5 are formed in the base end portions of the tightening portions 3, the tightening portions 3 can be easily held with a clamping tool H such as a clipper, and the tightening portions 3 can be easily plastically deformed. Moreover, the tightening space 4 can be reliably narrowed.

By forming the loosening prevention device 10, there is no possibility that the tightening space 4 of the tightening part 3 will expand due to a strong unexpected external force, etc., and the fixed state of the pipe P can be maintained reliably. . Moreover, the structure of the loosening prevention device 10 itself becomes simple, and it can be easily attached to the depression 5 portion.

As explained above, according to the present invention, pipes such as plumbing pipes and electric conduits can be firmly and easily fixed and supported on a mounting plate having mounting holes or other appropriate members, thereby improving work efficiency and work efficiency. It is possible to improve the safety of people, and it has a simple structure, is suitable for mass production, can be made lightweight, and is ideal for disposable use, which is extremely beneficial in practical terms.
