Description

[Detailed description of the invention] Industrial field of application This invention relates to an improvement in a hanging fitting for piping used when piping such as a cold water pipe or a steam pipe is suspended from a ceiling or the like.

BACKGROUND ART Conventionally, when supporting this type of piping, as shown in FIG. It holds the pipe H and supports and fixes it with a hanging fitting T attached to its upper part.

Problems that the invention aims to solve However, this method requires a heat insulating material U inside the band B, which makes it expensive, and also causes various problems such as the band becoming large and difficult to handle and requiring multiple installations. have

Means for Solving the Problems This idea was devised in view of the problems of the prior art, and is a piping hanging bracket that has a connection part with a female thread or a male thread on the head and a mounting piece with a mounting hole drilled at the bottom. is characterized in that at least the main part of the outer surface of the mounting piece and the inner peripheral surface of the mounting hole are covered with a heat-insulating and vibration-proofing material made of synthetic resin, etc., and the purpose thereof is to It is an object of the present invention to provide a hanging fitting for piping that is small and economically advantageous while improving workability.

Function The pipe hanging fitting with the above structure directly holds the pipe with a band, and is attached via a mounting piece covered on the top of the band, so that heat conduction from the pipe and slab transmitted to the band is prevented by the covering of the mounting piece. cut off at the section.

Therefore, there is no need to hold the heat insulating material with a band, and the simple structure is inexpensive, and moreover, reliable construction and improved efficiency can be expected, eliminating complication in construction and difficulties in handling. be able to.

Embodiments Hereinafter, embodiments of this invention will be described in detail based on the drawings.

FIG. 1 is a partially central longitudinal sectional front view of a piping hanging fitting according to a first embodiment of this invention, and FIG. 2 is a side view of the same, with reference numeral 1 indicating the piping hanging fitting.

2 is a suspension having a head 2a formed by bending a strip plate to form a generally triangular frame at the upper part, and a mounting piece 2b integrally formed at the lower part with mounting holes 2c which are appropriately extended and overlapped. In the main body of the metal fitting, an insertion hole 2b is provided on the top surface of the head 2a, and locking pieces 2e, 2e that protrude inwardly from each other are provided on both end surfaces thereof.

Note that 3 is a cavity.

Reference numeral 4 denotes a collar portion 4a for preventing slipping off at the lower end at a connecting portion, which is a rotatable female screw that is attached to the insertion hole 2b on the top surface of the head 2a and is locked on the lower surface by locking pieces 2e, 2e. A hexagonal spanner hook portion 4b is formed on the outer periphery upwardly.

Reference numeral 5 denotes a covering part made of synthetic resin or the like that covers the entire outer surface of the mounting piece 2b and the inner peripheral surface of the mounting hole 2c in the hanging fixture main body 2, and is coated with a heat insulating material such as polyethylene resin or rubber by dipping, for example. , which is coated with anti-vibration material.

Note that the means for attaching the connecting part 4 to the hanging fitting main body 2 may be any means other than the above-mentioned locking pieces 2e and 2e as long as it can be attached rotatably after being inserted into the insertion hole 2b of the hanging fitting main body 2. The means of

An example of how the piping hanging fitting 1 of the first embodiment configured as described above is used will be described below.

As shown in FIG. 3, in order to hold the pipe H directly in the band B, the tightening pieces B1,
The mounting piece 2b of the reinforcement hanging fixture 1 is interposed between B1 and fixed by tightening with bolts A and nuts N.

Next, attach a spanner (not shown) to the connecting shaft L that hangs down from the insert I that has been buried in the slab S in advance.
The height is adjusted by screwing in the connecting portion 4 of the piping hanging fitting 1 using a screwdriver or the like.

Thereafter, a heat insulating material U1 made of rock wool, glass wool, or the like is wrapped around the pipe H in order to cover the band B and the mounting piece 2b of the pipe hanging fitting 1.

In this way, the piping hanging fitting 1 of the first embodiment
According to the method, since the band B directly holds the piping H, the diameter of the band B can be smaller compared to conventional products that require a hard urethane foam insulation material U, and the construction is easy. Moreover, it can be done quickly, and has excellent economic efficiency and workability.

In addition, the pipe hanging fitting 1 and the band B are connected to each other at the covering part 5.
Piping H and slab S are completely insulated.
It prevents condensation, improves heat insulation, and has excellent anti-vibration performance.

Furthermore, when attaching the piping hanging fitting 1 to the band B, the bolt A can be temporarily secured by the covering part 5 around the mounting hole 2c, so there is no risk of the band B bolt A falling during the installation process. It has various excellent effects and is extremely effective in practice.

Next, another example of this invention will be explained.
FIG. 4 is a front view of the second embodiment, in which the hanging fitting 21 has a connecting part 24 with a male threaded shaft on the head, and a flat mounting piece 22b with a mounting hole 22c extending appropriately downward from the connecting part 24. In addition, the mounting piece 22b is provided with a covering portion 25 similar to that of the first embodiment, which has the effect of increasing reliability in terms of strength and being able to be provided at a low cost.

In addition, when using this, it can be installed by directly screwing into the insert I buried in the slab S.

FIG. 5 is a central vertical cross-sectional view of the covering part in the piping hanging fitting of the third embodiment. 35b and the locking hole 35b at the top.
The locking piece 35c that locks the locking piece 35c is formed with a bulging hollow cylindrical locking part 35b, and if necessary, it can be overlapped from the outer surface of the existing hanging fitting at the site. It can be attached and the same effects as described above can be obtained.

Note that the covering portion in the above embodiments is not limited to the above form, and any method may be selected, such as a tube heat shrink method.

Effects of the invention As explained in detail above, according to this invention, the hanging fitting and the band can be completely insulated by the covering part of the mounting piece, thereby blocking heat conduction from the piping and slab, preventing dew condensation, and providing insulation. It also has excellent anti-vibration performance.

In addition, according to this invention, even if the pipe is held directly by the band as described above, the covering part of the mounting piece of the hanging fitting can block heat conduction and vibration from the pipe and the slab. There is no need to hold the urethane foam as a material with a band, and the diameter of the band can be small, so it is small and easy to handle, and it has excellent economic efficiency and workability, such as easy and efficient construction. Therefore, it is possible to obtain a hanging fitting for piping that is extremely effective in practice.
