Description

[Detailed explanation of the invention] [Industrial field of application] Piping used in power plants and plants usually has multiple bends, but in this case, there are only a few bends in the bends at the bends in the parts that are subject to large displacements due to expansion and contraction due to temperature changes. This results in areas where no displacement occurs. For the former, slow displacement due to temperature changes is allowed, but sudden displacement due to earthquakes, etc. is restrained by supporting with snap bars. However, since snap bars are expensive for the latter, they are supported using a restraint that restrains only sudden vibrations. The present invention relates to an improvement of a restraint.

[Conventional technology]

What is often used as a restraint is one in which one end of a rod-shaped body is secured to a structure and the other end is secured to a pipe with a pin. However, the required length of the restraint varies depending on where it is attached. The length is manufactured in advance based on calculations on the diagram and delivered to the site, but conventional structures lack the ability to finely adjust the length during installation. For this reason, the piping support was forced to be strained, which caused unexpected failures over time. In addition, the locking pins at both ends were not necessarily perpendicular to the axis of the rod-shaped body, and there was also a defect that minute vibrations caused by the fluid in the tube caused rapid wear of the pins.

[Means to solve problems]

In order to make the length of the rod-like body adjustable, one end is provided with a turnbuckle function, and the other end is provided with an elastic ring to absorb minute vibrations. When it is necessary to deal with the angular deviation between the rod-shaped body and the locking pin, a structure in which the pin is supported by a spherical surface is adopted.

〔Example〕

The drawings will be explained. The tubular body 1 has lids 1a and 1b integrated at both ends. Bracket 2
is fixed to the structure at the base, and a ball 3 is attached to the clevis.
is secured with pin 4. The stopper fitting 5 has a handle 5b protruding from one side of a collar 5a, and a threaded rod 5c protruding from the other side. A round hole is bored in the handle 5b, and the ball 3
The threaded rod 5c is locked to allow spherical movement to the lid 1.
A is passed through. The locking fitting 5 can hold the lid 1a between a collar 5a and a ring 6 inserted into a threaded rod 5c, and can be tightened with a nut 7, and elastic rings 8 are inserted on both sides of the lid 1a. As the elastic ring, a product obtained by stacking stainless steel wire mesh and pressing to form the ring is commercially available, and this may be used. The turnbuckle 9 has a cylindrical body and rotatably passes through the lid 1b. Its inner end is provided with a collar 9a, and its outer end is threaded. The lid 1b can be held between the nut 10 and the collar 9a which are screwed together. The turnburcle 9 also has a threaded hole formed therein in the axial direction, through which the eye bolt 14 is threaded. Spanner hook part 9b on turnburkle
Since this is provided, the eye bolt 14 can be adjusted in and out by loosening the nut 10 and turning the wrench hook. A pin 13 having a ball 12 is provided in the band 11 of the pipe P, and the outer end hole of the eye bolt 14 is locked to the ball for spherical movement.

FIG. 2 shows another embodiment in which the pipe is supported by two restraints.

[Effects] In the present invention configured as described above, the overall length can be freely adjusted within a certain range by adjusting the turnbuckle 9. Since the elastic ring absorbs minute vibrations, it does not adversely affect the locking pin. Although a spherical connection at both ends is not necessary, it is useful to prevent wear if the locking pin is angled incorrectly. A feature of the present invention is that as long as the approximate length is determined, it can be easily and reasonably fastened on site.

Claims (1)

[Claims for Utility Model Registration] (1) A tubular body with lids at both ends, one end of which is locked with a pin to the bracket of the structure, and the other end of which can hold the lid at one end of the body from the inner and outer surfaces through elastic rings, respectively. A retaining metal fitting with a flange and a nut is provided at the other end of the main body, and a flange and a nut are rotatably inserted into the lid at the other end of the main body so that the lid can be held. A pipe support restraint comprising a turnbuckle, and a threaded rod that is threaded through the turnbuckle and whose outer end is locked with a pin to a pipe gripping band fitting. (2) In the restraint described in claim 1 of the utility model registration, the outer ends of the locking fitting and the threaded rod are each supported by a locking pin on a spherical surface.
