Description

[Detailed explanation of the invention] (a) Industrial application field This invention is designed to treat low-temperature piping and the heat insulating support member such as hard polyurethane foam that supports it, and the piping and the heat insulation support member in which failure due to relative displacement due to the difference in thermal contraction occurs. This invention relates to a support device for low-temperature piping that prevents both.

(b) Prior art Conventionally, a structure as shown in Japanese Utility Model Publication No. 57-25021 has been proposed as this type of support device for low-temperature piping. The protruding flange members were welded to predetermined positions on both sides of the support member in the axial direction, and then the support member was fitted between the two flange members, and the coating was applied to the through hole of the flange member and the inside of the support member. The screw holes of the mounting member, which can be slid in the axial direction, are aligned through the release material and screwed together with bolts.

(c) Problems that the device is intended to solve However, such conventional support devices for low-temperature piping not only required a lot of time and effort for assembly, such as fitting the support member between the flange members, aligning the through holes of the flange members with the screw holes of the support member, and screwing them in place with bolts, but also had the problem that the structure was complex and the manufacturing costs were inevitably high.

(d) Means for solving the problem This invention was made by focusing on such conventional problems, and it is a method for sliding the mounting jig fixing member and the mounting jig welding member in the piping direction. Connect the holes and male and female sliding fittings such as protrusions, temporarily fix them together with adhesive, and attach the mounting jig fixing member to the upper part of both ends in the piping direction of the heat insulating support member, such as hard polyurethane foam, with screws, etc. The object of the present invention is to provide a support device for low-temperature piping, which is formed by welding the piping and the upper side of the mounting jig welding member.

(e) Function The function of this invention will now be explained.

After assembly and construction, when low-temperature fluid is flowed through the piping, the piping and insulating support members such as rigid polyurethane foam are cooled, and the shrinkage due to the low temperature differs between them.
A tensile force acts between the mounting jig welding member welded to the pipe and the mounting jig fixing member fixed to the heat insulating support member. At that time, the adhesive surface that temporarily fastened the welding member and the fixing member peels off, and the male and female sliding fittings connecting them slide in the direction of separation from each other, that is, in the direction of shallower fitting. It absorbs movement due to contraction, and conversely, when the flow of the low-temperature fluid flowing through the piping stops and the temperature rises, the male and female sliding fittings slide in the direction of deepening the fitting with each other. It absorbs the movement caused by restoration.

(F) Embodiment An embodiment of the present invention will be described below with reference to the drawings.

The mounting jig fixing member 1 and the mounting jig welding member 2 are connected by a male and female sliding fitting such as a hole 3 and a protrusion 4 that slide in the piping direction, and are temporarily fixed together with an adhesive 5. . Then, the mounting jig fixing member 1 is attached to the top of both end surfaces 8, 8 in the piping direction of the heat insulating support member 7, such as hard polyurethane foam, which supports the pipe 6. Fix it with screws 10, 10, etc. in a position where it will come into contact with the. Then, the piping 6 and the upper side 9 of the mounting jig welding member 2 are welded. 11 is a cold insulating material for keeping the pipe 6 cool; 12 is a waterproof sheet metal of the cold insulating material 11;
3 is a bearing plate fixed to the heat insulating support member 7.

(G) Effects of the invention As explained above, according to this invention,
Its structure is such that the mounting jig fixing member and the mounting jig welding member are temporarily fixed together by being deeply fitted with their male and female sliding fittings, and their abutting surfaces are bonded with an adhesive. Therefore, by fixing one of the mounting jig fixing members to the required positions on both end faces of the heat insulating support member, such as hard polyurethane foam, with screws, etc., welding of the welding member of the mounting jig to the piping becomes easy. Not only that, but it also allows the mounting jig to be installed easily and quickly, and the mounting jig can be used when the heat insulating support member contracts after installation due to low-temperature fluid flowing through the pipes and the pipes becoming cold. The welded surfaces of the fixing member and the welded part of the mounting jig will peel off, and the male and female sliding fittings can slide freely within a range that does not deviate, so unreasonable stress will not be applied and damage to the heat insulating support member will be ensured. This can be avoided.
