Description

[Detailed Description of the Invention] (Industrial Application Field) This invention relates to a device for supporting piping that expands and contracts due to heat in chemical plants and the like.

(Prior art) Conventionally, when a pipe that is displaced by heat in the direction of the pipe axis and a direction perpendicular to the pipe axis is supported on a support stand with a U-shaped bolt, the pipe and the U-shaped bolt are connected to each other in order to allow the displacement. A predetermined gap is left between the bolt and the bolt.

(Problems to be solved by the invention) In the conventional piping support method as described above,
During installation work, it is time-consuming to measure the gap between the piping and the U-shaped bolt each time.
Furthermore, it is powerless to suppress vibrations of piping caused by earthquakes and the like. This invention attempts to solve the above-mentioned conventional problems.

(Means for solving the problem) In this invention, in order to solve the above problem, a plurality of cylinders are attached to the U-shaped bolt 2 so as to be interposed between the U-shaped bolt 2 and the pipe P. A thin metal wire entwined body 3 having a shape of 1.5 mm is rotatably inserted therein.

(Function) In this invention, installation is completed by tightening the U-shaped bolt 2 until the thin metal wire entanglement 3 lightly contacts the pipe. Displacement in the direction perpendicular to the tube axis of the piping system is easily allowed due to the elastic deformation of the metal thin wire entanglement 3, and displacement in the tube axis direction is easily allowed by the elastic deformation of the metal thin wire entanglement 3.
This is also easily allowed by relative sliding with the metal wire entanglement body 3 or rotation of the thin metal wire entanglement body 3. Vibrations of the pipe P due to earthquakes and the like are buffered and suppressed by the metal thin wire entanglement 3. The cylindrical thin metal wire entanglement body 3 is
Depending on the size of the U-shaped bolt 2, the number can be adjusted appropriately to apply it to U-shaped bolts 2 of any size.

(Example) In FIG. 1, a plurality of support stands 1 are installed along the pipe axis direction of the pipe P at appropriate intervals. The U-shaped bolts 2 are fixed on each support stand 1 across the pipe P. Cylindrical thin metal wire entanglement body 3
A plurality of U-shaped bolts 2 are successively inserted into the U-shaped bolt 2 so as to be interposed between the pipe P and the U-shaped bolt 2. Each thin metal wire entanglement body 3 is rotatable with respect to the U-shaped bolt 2. The metal fine wire entanglement 3 is, for example, made by knitting fine stainless steel wires into a mesh and compression-molding it into a cylindrical shape. Depending on the length of the U-shaped bolt 2, the number of metal wire entanglements 3 can be increased or decreased appropriately to form a U-shaped bolt. It shall be inserted. The U-shaped bolt 2 is fixed to the support base at a position where the thin metal wire entanglement 3 lightly contacts the pipe P.

In this case, when the pipe P is displaced in the pipe axial direction, the metal fine wire entanglement 3 slides on the pipe P or rolls relative to the pipe P to allow the displacement.
Further, when the pipe P is displaced in a direction perpendicular to the pipe axis, the metal fine wire entanglement 3 contracts and allows this without difficulty.
The thin metal wire entanglement 3 also absorbs vibrations of the pipe P due to earthquakes, etc., and performs a vibration-proofing effect.

In another embodiment shown in FIG. 2, a support rod 4 is installed in a direction orthogonal to the pipe P so as to be interposed between the pipe P and the support stand 1. The support rod 4 has a hook 4a at one end into which the leg of the U-shaped bolt 2 is inserted, and a threaded portion 4b at the other end screwed into the eye fitting 5. The eye fitting 5 has a threaded portion 5a and a hole 5b through which the other leg of the U-shaped bolt 2 is inserted. A plurality of cylindrical thin metal wire entanglements 6 are attached to this support rod 4.
is inserted between the support rod 4 and the pipe P. The support rod 4 can be applied to various U-shaped bolts 2 of different sizes by screwing and adjusting the eye fittings 5.

In this case, displacement of the piping P in both the direction opposite to the support base 1 and the direction toward the support base 1 is allowed by compression, and vibrations are damped.

(Effect of the invention) As explained above, this invention
a U-shaped bolt 2 fixed to the support base 1 across the piping P on the support base 1;
Since the configuration includes a plurality of cylindrical thin metal wire entanglements 3 that are rotatably inserted into the U-shaped bolt 2 so as to be interposed between the U-shaped bolt 2 and the piping P, the piping P It is possible to provide a piping support device that can reasonably tolerate displacement due to heat, can effectively suppress vibrations caused by earthquakes, etc., and is easy to install.
