Description

  The present invention relates to a heat insulating coated copper pipe fixing bracket for fixing a heat insulating coated copper pipe used in an air conditioner to a channel material. In particular, the present invention relates to two heat insulating coated copper pipes used as a gas pipe or a liquid pipe. The present invention relates to a heat-insulating copper tube fixing metal fitting and a fixing method that can be installed compactly as a set.

  Conventionally, two heat-insulated coated copper pipes of different diameters used as gas pipes and liquid pipes of air conditioners are arranged side by side on a channel material as described in Patent Document 1, for example, and a step is formed. There is a means for fixing the generated tube side surface to the channel material while pressing the side surface of the tube with a contact support portion adapted to the step.

  In addition, as described in Patent Document 2, there is also a means for fixing the side surfaces of two heat-insulated coated copper tubes arranged side by side on the channel material to the channel material with a pipe fixing band.

  As described above, the two heat-insulated copper pipes having different diameters used as gas pipes and liquid pipes of the air conditioner have been installed by fixing them side by side on a channel material or an angle material.

  On the other hand, the heat-insulated coated copper tube is obtained by coating the periphery of a copper tube with a foamed resin or the like. For this reason, the outer surface of the heat-insulated copper pipe has a problem in weather resistance, and there is also a risk of being damaged by birds such as dragging and crows during piping construction. For this reason, a protective cover such as a decorative duct is attached to the heat-insulated copper pipe after piping to protect the heat-insulated copper pipe fixed to the channel material or the angle material.

Patent Document 3 describes a heat-insulating pipe fixing bracket that fixes two heat-insulated coated copper pipes arranged above and below the opening of a channel material together. The fixing metal fitting is a small-diameter heat-insulated copper pipe placed directly on a large-diameter heat-insulated copper pipe placed on a channel material. These heat insulation coated copper tubes are fixed by a frame fixed to the channel material while two heat insulation coated copper tubes are pressure-bonded to the channel material with operation bolts that press and urge in the direction.
