Description

[Detailed Description of the Invention] [Field of Application of the Invention] The present invention relates to a support for piping, and in particular to a piping support that supports piping with a receiving part on the upper surface of an upright part constructed on a base plate. Regarding supports.

[Background of the Invention] As shown in FIG. 1, FIG. 2, and FIG. 3, a conventional pipe support of this type includes a pipe support stand 1, a base part 2 that is installed on a foundation material, etc. A rising part 3 constructed on the foundation part 2 and having a height
There is one that is provided with a receiving part 4 which is provided on the rising part 3 and on which piping can be freely placed.

Supporting piping with this type of piping support is the first step.
As shown by the imaginary line in the figure, the pipe 7 is placed orthogonally on the receiving part 4, and a U is placed on the outer circumference of the pipe 7.
Straddle the U-shaped bolt 8 and insert both ends of the U-shaped bolt 8 into a pair of through holes 5 drilled in the base 2, and attach a pair of nuts 9, 9 to both ends of the U-shaped bolt 8. Screw each part on the back side of part 2,
This is done by tightening the U-shaped bolt 8 by screwing the nuts 9, 9, and thereby fixing the pipe 7 to the receiving part 4 and supporting it on the support base 1.

Conventionally, this type of pipe support stand 1 has been manufactured as follows. That is, the pipe support stand 1 shown in FIG. 1 is manufactured by integrally casting the base part 2, the rising part 3, and the receiving part 4, and the pipe support stand 1 shown in FIG. 4 are integrally formed into a V-block shape by casting or forging, and this V-block-shaped body is fixed to the upper surface of the flat plate-shaped base part 2 via a welding part 6. Piping support stand 1 shown in Figure 3
is manufactured by individually forming the base part 2, the rising part 3, and the receiving part 4 into a predetermined plate shape by forging or cutting, and then connecting and integrating these separate parts through a welded part. ing.

However, for such a structure, if a mold is used, the price will be high, even if a sand mold is used, it is not suitable for mass production, and if forging, bending, or welding work is involved, it will be expensive. The manufacturing process is extended, the setup is multidimensional, and it is necessary to remove welding distortion after welding, making the manufacturing even more complicated, which has the disadvantage that it is not suitable for mass production. Furthermore, since the piping 7 is rigidly fixed to the piping support, there is a drawback that the piping 7 cannot be expanded and contracted due to temperature changes. That is, the pipe 7 expands and contracts in the axial direction and radial direction due to temperature changes. In particular, if the piping is constructed with a length of several meters, the amount of expansion and contraction due to temperature changes will be large, and if the piping is fixed rigidly by the piping support, there is a risk that the piping will be damaged.

[Purpose of the invention]

SUMMARY OF THE INVENTION An object of the present invention is to eliminate the drawbacks of the prior art described above, to provide a pipe support suitable for mass production, and to provide a pipe support that can tolerate shrinkage of the pipe due to temperature changes.

[Summary of the invention]

In order to achieve the above-mentioned object, the present invention provides a U-shaped bolt which is installed over the outer circumference of a pipe and has two pairs of nuts;
The U-shaped bolt is fixed to the foundation member, and the piping is connected to the U-shaped bolt.
The supporting member is integrally formed from a plate material by press working, and the U-shaped bolt for fixing the supporting member passes through at least one support member.
a base portion having a pair of holes; a raised portion that rises to hold the piping at a predetermined distance from the base portion; and at least a portion of the boundary with the base portion protrudes toward the inner surface; A support surface part whose upper end is bent inward to form a support surface for the piping, and both ends of the base plate part are bent toward the base member and a gap is formed between the base member and the base member. It is characterized by having a protrusion that elastically deforms when the bolt is tightened to elastically support the piping on the base member.

[Example] Hereinafter, an example of the present invention will be described with reference to the drawings.

In FIG. 4 showing one embodiment of the present invention, a pipe 70 is clamped and fixed between a U-shaped bolt 40 and a support surface 24 on the top of a pipe support 20 placed on a base member 30. Piping support 20 is U bolt 40
A base plate part 22 having a hole 25 through which both legs pass through, a raised part 23 formed by bending one end of the base part 22, and a support surface for piping formed by bending the tip of the raised part 23 into a V shape. Consists of 24. Board part 2
A portion 27 of the boundary between 2 and the rising part 23 bulges out, increasing the mechanical strength of the rising part, so that the rising part does not buckle. Further, protrusions 22A, 22A are formed at both ends of the substrate portion 22 to be bent toward the base material 30, so that the piping support 20 is elastically supported on the base material 30.

Since this piping support can be integrally formed by press working, it can be mass-produced at a lower cost than an integrally molded product by casting, and is also cheaper than one that requires manufacturing processes such as forging, cutting, bending, and welding. too,
It can be mass-produced in a short time and saves labor.
Moreover, since it has a reinforced part that bulges on the upright part,
Even if the wall thickness is small, it exhibits sufficient strength, so
It is also possible to reduce the amount of material used.

The piping support 20 is placed on the base material 30, and the piping 70 is
is fixed with U-shaped bolts 40. The U-shaped bolt 40 is fixed to the base material 30 with a pair of nuts 42. U
When tightening the type bolt 40, the piping 70 is pressed from the support surface 24 due to elastic deformation of the protrusions 22A provided at both ends of the base plate 22, and the U-bolt 40 and the support surface 2 are pressed together.
4 and held under pressure. In addition, the substrate section 22
Since the protrusions 22A, 22A are formed at both ends, a gap is formed between the base material 30 and the substrate part 22. Therefore, the protruding portion 22A of the substrate portion 22,
The piping 70 is elastically supported by the base material 30 by 22A. This results in the following advantages:
That is, the piping 70 is not rigidly installed,
It is not a free installation, but is supported elastically. As a result, although the piping 70 is normally supported immovably, it expands and contracts when there is a temperature change, but since the piping 70 is not rigidly fixed, it expands and contracts while being supported by the support. Therefore, the piping will not be damaged.
Furthermore, since the piping is elastically supported by the protruding parts 22A, 22A of the base plate part 22, it also has the function of preventing the nut 42 of the U bolt 40 from loosening.

In the above embodiment, the case where the piping is fixed on the support stand using a U-shaped bolt has been explained, but the means for fixing the piping on the support stand is not limited to the U-shaped bolt, for example, an elastic band, etc. Furthermore, such a positioning means can be omitted. In addition, although only the case where a single support is used has been described, a pair of supports may be arranged with the standing parts back to back.
In this case, the support of the vertical piece in the upright state by the base portion is ensured, and the supporting capacity of the piping load is further strengthened. It is even better if the rising parts placed back to back are connected to each other by any means. Although a case has been described in which the reinforcing protrusion is bulged toward the substrate portion, the reinforcing portion may be bulged toward the opposite side.

〔Effect of the invention〕

As explained above, according to the present invention, support stands for piping supports can be mass-produced by press working. Furthermore, since the piping is elastically supported by the protrusion of the piping support, even if the piping expands or contracts due to temperature changes, the piping can be moved and the piping will not be damaged.
