Description

[Detailed Description of the Invention] The present invention relates to a device for supporting piping through which low-temperature fluid such as liquefied gas flows.

The low-temperature piping is partially fixed to a structure such as a support beam through a block made of synthetic resin such as hard urethane foam. For this reason, the blocks need to be fixed to piping or metal bands for binding the blocks. However, conventional fixing means have been using tapping screws or adhesives. When using screws, highly reliable fixing strength cannot be obtained, and when using adhesives, the adhesive surface may be damaged during the bonding process. There are problems such as the need for cleaning, etc., and the need to interrupt work during the resting period for the adhesive to dry.

The present invention was developed by focusing on the above-mentioned problems with conventional pipe support devices, and uses lugs welded to the pipes to hold both outer sides of a block divided into two parts, and also uses cable ties to hold the two outer sides of the block. By inserting a lug welded to the inside of the block into the gap between adjacent blocks and joining the pipe to the band fitting, the use of unreliable tapping screws and adhesives with poor workability can be eliminated. The purpose is to provide a support device.

Embodiments of the present invention will be described below with reference to the figures. A cold insulating material 2 is attached to the outer periphery of the low temperature pipe 1. Blocks 3 made of hard synthetic resin, such as hard urethane foam, are attached to the outer periphery of the piping 1 at required locations, which are divided into a plurality of parts in the circumferential direction by cutting out a part of the cold insulation material. The block 3 is also divided into two in the direction of pipe extension. The outside of each of these blocks 3 in the direction of pipe extension is sandwiched by a pair of lugs 4 welded to the outer periphery of the pipe 1 so as to face each other.

The band fitting 5 that binds the blocks 3 is made of a pair of arc-shaped halves that are butted together at both ends and tightened with bolts and nuts, and a lug 6 that intervenes in the gap between the adjacent blocks 3 is located at the center of the inside of the band fitting 5. is welded. Note that the remaining space between the blocks 3 and 3 is filled with a cold insulating material. The outside of the band fitting 5 is supported on a structure S such as a support beam or a floor via a mounting seat 7, and the piping 1 is restrained in the radial direction. In addition, when the displacement of the piping 1 in the extension direction is also restrained, the mounting seat 7 is fixed on the structure S.

Note that FIGS. 1 to 3 show a case in which the block 3 is divided into two in the circumferential direction and fixed onto the support surface of the structure S, and FIG. 4 shows a case in which the block 3 is divided into three in the circumferential direction and The case where it is fixed into the groove of the construct S is illustrated.

Next, the action will be explained. The pipe 1 is held by the block 3, the pipe 1, and the lugs 4 and 6 of the band fitting 5, and is prevented from moving in the axial direction due to temperature changes or the like. The lug 4 of the pipe 1 and the lug 6 of the band fitting 5, which are at a low temperature, face each other apart from each other with the block 3 in between, and are separated from each other in the vertical direction, so that there is little heat conduction.

As described above, in the present invention, the low temperature piping 1
A synthetic resin block 3 divided into a plurality of parts in the circumferential direction is attached to the outer periphery of the block 3, and lugs 4, 4 are welded to both sides of the block 3, and the outer periphery of the block 3 is bound with a band fitting 5. A lug 6 is provided inside the band fitting 5 to cooperate with the lug 4 of the piping 1 to fix the block 3 in the extending direction of the piping.
In the support device for low-temperature piping, in which a mounting seat 7 is fixed to the outside and this mounting seat 7 is supported on a structure S, the block 3 is further divided in the extending direction of the pipe 1, and the band fitting 5 is fixed at a position intervening in the gap S between adjacent blocks 3 in the direction of pipe extension, and
Since the lug 4 of the piping 1 and the lug 6 of the band fitting 5 do not face each other but are separated as far as possible with the block 3 interposed between them, there is little heat conduction between them, and therefore, the cold insulation is reduced. In addition to being able to enhance the effect, the band metal fittings 5 and the mounting seat 7
It has the effect of being able to prevent freezing.
