Description

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

  As shown in FIG. 8, the pipes 60, 60 supported in a substantially horizontal direction by the hanging metal fittings 50, 60 are “crushed pipe covering parts” by their own weights in the supporting parts (band parts) 51 of the hanging metal fittings 50. ”And“ piping of the pipe covering part ”may cause a decrease in heat insulation and heat insulation functions, resulting in a serious defect such as condensation and heat loss.

As means for preventing this, there is a hanging metal fitting 70 disclosed in Non-Patent Document 1. The suspension fitting 70 shown in FIG. 9 is obtained by increasing the support area of the band portion 71 (pipe support portion) of the suspension fitting 70 in the longitudinal direction of the pipe. Reference numeral 80 denotes a pipe.

Certainly, by increasing the support area of the band part 71 of the hanging metal fitting 70, the weight of the pipe 80 is dispersed, and problems such as “crushing of the pipe covering part” and “breaking of the pipe covering part” can be prevented.
However, the hanging metal fitting 70 has the following problems.
(1) Since it is integrally molded, manufacturing is complicated and cost increases. Moreover, since it cannot be disassembled by integral molding, the bulk increases when stored in a box or case, which is unsuitable for storage.
(2) Since it is integrally molded, various types corresponding to the type of piping are required, and a large number of product lineups are required.
(3) If a plurality of suspension fittings are used depending on the type of piping and the laying situation of the piping, inventory management of the suspension fittings becomes difficult. In particular, in a wholesale store where inventory management is required or in a site where a hanging bracket is actually required, the complexity becomes an extremely heavy burden.

  In view of the above, the present invention has been completed by conducting intensive studies and research in order to solve the above-mentioned problems and provide a new auxiliary member for a hanging bracket and a hanging bracket.

In order to achieve the above object, the first invention is an auxiliary member for a hanging fitting used for a hanging fitting for supporting a pipe, and is interposed between a band portion of the hanging fitting for holding the pipe and the pipe. In this way, it extends in the longitudinal direction of the pipe.
The second invention is an auxiliary member for the hanging metal fitting that is fixedly attached to a band portion of the hanging metal fitting.
A third invention is an auxiliary member for the hanging bracket that is divided in the longitudinal direction of the pipe and is fixedly attached to a band portion of the hanging bracket.
A fourth invention is an auxiliary member for the hanging bracket that is detachably attached to a band portion of the hanging bracket.
A fifth invention is a hanging metal fitting provided with first to fourth auxiliary members for a hanging metal fitting.

The present invention has the following effects.
(1) The auxiliary member for the hanging metal fitting of the present invention has a decrease in heat insulation and heat insulation function due to problems such as “crushing of the pipe covering portion” and “breaking of the pipe covering portion” in the band portion (supporting portion) of the hanging fitting, It is possible to prevent and reduce serious defects such as the occurrence of condensation and heat loss. In particular, it is effective for coated copper pipes for refrigerant and pipes with other coatings (heat insulating materials) (for example, trade name “SC PEX” manufactured by Showa Corporation), but is not limited thereto.
(2) Since the auxiliary member for the hanging metal fitting of the present invention is not integrally formed with the hanging metal fitting and can be attached to an existing or new hanging metal fitting, there is little problem in terms of manufacturing cost.
(3) The auxiliary member for a hanging metal fitting of the present invention is not integrally molded, and an existing hanging metal fitting can be used, so that the problem of product lineup hardly occurs.
(4) Since the existing hanging bracket can be used, it is not necessary to prepare a plurality of types of hanging brackets depending on the type of piping and the laying status of the piping, and the problem of inventory management is unlikely to occur.
(5) Since the auxiliary member for a hanging metal fitting of the present invention can be used for existing piping (existing piping) supported by the hanging fitting, it is extremely useful.
