Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an auxiliary member used in a sling fitting for supporting piping.

Pipes supported in a substantially horizontal direction by hanging metal fittings (horizontal pulling pipes) are caused by defects such as "collapse of the pipe covering" or "torn of the pipe covering" due to their own weight at the support part (band part) of the hanging metal fittings. It may lead to deterioration of heat retention and heat insulation function, causing 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 Edition), in order to prevent the insulation material from encroaching in the case of horizontal pipe support, It is recommended to install a protective plate made of synthetic resin or the like (referred to in the present application as "auxiliary member for hanging fitting") between them.
Various auxiliary members for hanging fittings that extend in the axial direction of the pipe so as to be interposed between the band portion of the hanging fitting that holds the pipe and the pipe to support the pipe have been researched and developed. (For example, Patent Document 1, etc.).

JP 2010-48339 A

Looking at the prior art documents, it is true that by increasing the support area of the band portion of the hanging fitting, the weight of the pipe itself is dispersed, and problems such as "crushing of the pipe covering" and "tearing of the pipe covering" occur. can be prevented.
However, conventional sling fitting auxiliary members have the following problems.
(1) In order to maximize the effect of the auxiliary member for the hanging fitting, it must be installed (arranged) with good balance between the band portion of the hanging fitting and the pipe so as to receive the weight of the pipe. Ideally, they should be installed (arranged) evenly in the axial direction of the pipe around the band portion of the hanging fitting, and evenly in the lower circumferential direction of the pipe. If auxiliary members for hanging fittings are installed (arranged) unevenly between the band of the hanging fitting and the pipe, the load will be applied only to a specific part of the pipe, resulting in "collapse of the pipe covering" or "damage to the pipe covering." This is because trouble such as tearing may occur.
(2) However, in the construction work of actually laying the pipes on the hoisting fittings, the auxiliary members for the hoisting fittings also slide in conjunction with the movement of the pipes when the pipes are bridged to the hoisting fittings. It was necessary to adjust the position of the auxiliary member for the hanging bracket after laying the pipe because it could not be installed (arranged) between the band and the pipe in a well-balanced manner. In addition, once the equipment starts operating, the auxiliary members for the lifting fittings may slide due to expansion and contraction of the pipes. In this case, it is practically impossible to adjust and maintain the position of the auxiliary members for the lifting fittings. (The same applies to vibrations and tremors caused by external factors such as earthquakes and contact between people and objects that are not caused by the piping itself.)
(3) For example, since the support plate B disclosed in Patent Document 1 (corresponding to the "auxiliary member for hanging fitting" in the present application) also has the insertion engaging body 12, However, since sliding in the circumferential direction (transverse direction of the pipe) is not restricted, it cannot be reliably installed (arranged) directly under the pipe. Therefore, it was 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 problems and provide an auxiliary member for a lifting fitting and a lifting fitting that can reliably fix the auxiliary member for the lifting fitting to the piping pipe in the axial direction and the circumferential direction of the piping pipe, we have conducted extensive testing and research. and completed the present invention.
