Description

  TECHNICAL FIELD The present invention relates to an auxiliary member used for a suspension fitting for supporting a pipe.

  Pipes (horizontally drawn pipes) supported in a substantially horizontal direction by the hanging fittings may cause problems such as "crushing of the pipe covering section" or "breaking of the pipe covering section" due to their own weight in the supporting portion (band section) of the hanging fitting. This may cause deterioration of the 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 Standard Specifications (Machine Equipment Construction), in order to prevent the penetration of insulation materials in the case of horizontal piping support, the insulation material-covered copper pipe and the hanging metal In between, it is recommended to install a protective plate such as a synthetic resin (referred to as “auxiliary member for hanging bracket” in the present application).
There have been various research and developments on auxiliary members for hanging fittings that extend in the axial direction of the piping pipe so as to be interposed between the band portion of the hanging fitting for holding the pipe and the pipe so as to support the pipe. (For example, Patent Document 1).

JP 2010-48339 A

According to the prior art documents, it is true that by increasing the supporting area of the band portion of the hanging bracket, the weight of the pipe is dispersed, and problems such as “crushing of the pipe covering part” and “breaking of the pipe covering part” are solved. Can be prevented.
However, the conventional auxiliary members for hanging fittings have the following problems.
(1) In order to maximize the effect of the auxiliary member for the hanging fitting, it must be installed (arranged) in a well-balanced manner between the band portion of the hanging fitting and the piping in order to receive the weight of the piping. Ideally, it should be installed (arranged) evenly in the axial direction of the pipe centering around the band portion of the hanging fitting, and further, in the direction of the lower circumferential axis of the pipe. When the hanging member auxiliary member is installed (arranged) biased between the band portion of the hanging member and the pipe, a load is applied only to a specific portion of the pipe, and “crushing of the pipe coating section” or “ This is because a problem such as "break" may occur.
(2) However, in the construction work for actually laying the pipes on the hanging fittings, the auxiliary member for the hanging fittings slides in conjunction with the movement of the pipes when the pipes are bridged to the hanging fittings, and the hanging fittings are not slid. It was not possible to install (arrange) the band portion and the pipe in a well-balanced manner, and it was necessary to adjust the position of the auxiliary member for the hanging fitting after the pipe was laid. In addition, when the operation of the equipment is started, the auxiliary member for the hanging fitting may slide due to expansion and contraction of the pipe. In this case, the position adjustment and maintenance of the auxiliary member for the hanging fitting are practically impossible. (The same applies to vibrations and shakes caused by external factors such as earthquakes and contact between people and things that are not caused by the piping itself.)
(3) For example, the support plate B (corresponding to the “auxiliary member for hanging metal fittings” in the present application) disclosed in Patent Document 1 also has the plug-in engagement body 12, so that the pipe pipe axis direction (pipe longitudinal direction). Is restricted, but sliding in the circumferential direction of the pipe (shorter direction of the pipe) is not restricted, so that it is not surely installed (arranged) directly below the pipe. Therefore, it is necessary to adjust the position of the auxiliary member for the hanging fitting in the circumferential direction of the pipe after laying the pipe.

  Therefore, in order to solve the above-mentioned problem, intensive tests and researches have been conducted to provide an auxiliary member and a metal fitting for a metal fitting that can securely fix the metal fitting for the metal fitting to the metal pipe in the axial direction and the circumferential direction of the metal pipe. As a result, the present invention was completed.
