Description

The present invention relates to an auxiliary member used for a hanging metal fitting for supporting a pipe.

The pipe (horizontal pulling pipe) supported in the substantially horizontal direction by the hanging metal fitting is caused by a defect such as "crushing of the pipe covering part" or "tearing of the pipe covering part" due to its own weight at the supporting part (band part) of the hanging metal fitting. It may cause deterioration of heat retention and heat insulation functions, and may cause serious defects such as dew condensation and heat loss.

For this reason, in the 2013 edition of the Ministry of Land, Infrastructure, Transport and Tourism Public Building Construction Standard Specifications (Mechanical Equipment Construction), in order to prevent the heat insulating material from biting in when supporting the horizontal piping, the heat insulating material-coated copper pipe and the hanging hardware are used. It is recommended to install a protective plate made of synthetic resin or the like (“auxiliary member for hanging metal fittings” in the present application) in between.
So far, various auxiliary members for hanging metal fittings that extend in the axial direction of the pipe pipe so as to be interposed between the band portion of the hanging metal fitting that holds the pipe and the pipe and support the pipe have been researched and developed. (For example, Patent Document 1 and the like).

Japanese Unexamined Patent Publication No. 2010-48339

According to the prior art documents, it is true that by increasing the supporting area of the band portion of the hanging metal fitting, the weight of the pipe is dispersed, and problems such as "crushing of the piping coating" and "tearing of the piping coating" occur. Can be prevented.
However, the conventional auxiliary members for hanging metal fittings have the following problems.
(1) In order to maximize the effect of the auxiliary member for the hanging bracket, it must be installed (arranged) in a well-balanced manner between the band portion of the hanging bracket and the pipe in order to receive the weight of the pipe. Ideally, it should be installed (arranged) evenly in the axial direction of the pipe pipe centering on the band portion of the hanging metal fitting, and further evenly in the lower peripheral axial direction of the pipe. If the auxiliary member for the hanging metal fitting is installed (arranged) unevenly between the band part of the hanging metal fitting and the pipe, a load is applied only to a specific part of the pipe, resulting in "crushing of the pipe covering part" or "crushing of the pipe covering part". This is because problems such as "tear" may occur.
(2) However, in the construction work of actually laying the pipe on the hanging metal fitting, the auxiliary member for the hanging metal fitting also slides in conjunction with the movement of the pipe when the pipe is bridged to the hanging metal fitting, and the hanging metal fitting It was not possible to install (arrange) the band and the pipe in a well-balanced manner, and it was necessary to adjust the position of the auxiliary member for the hanging bracket after laying the pipe. In addition, when the operation of the equipment is started, the auxiliary member for the hanging bracket may slide due to the expansion and contraction of the piping.

Therefore, it is necessary to adjust the position of the auxiliary member for the hanging metal fitting in the circumferential direction of the pipe after laying the pipe.

Therefore, in order to solve the above-mentioned problems and to provide the auxiliary member for the hanging metal fitting and the hanging metal fitting that can surely fix the auxiliary member for the hanging metal fitting to the hanging metal fitting in the axial direction of the piping pipe and the circumferential direction of the piping pipe, intensive tests and researches are conducted.
