Description

  The present invention relates to a saddle band, and more particularly to a saddle band that supports and fixes a pipe along a mounting surface such as a ceiling surface, a wall surface, and a floor surface.

  A saddle band is known as a pipe support that supports and fixes piping such as gas pipes, water supply pipes, and hot water supply pipes along installation surfaces such as a ceiling surface, a wall surface, and a floor surface in facilities construction such as buildings. In the saddle band, a double-pressing type that is fixed on both sides in the direction perpendicular to the pipe axis is called a double saddle, and a single-pressing type that is fixed on one side is called a single saddle.

  The single saddle generally holds the pipe from the lower open portion of the inverted U-shaped holding portion into the holding portion, and then extends from one end of the holding portion along the mounting surface. The pipe is supported and fixed by fixing the fixed end portion to the mounting surface with a fixing member such as a bolt.

  The single saddle can easily support and fix the pipe on the mounting surface with a very simple configuration, but in the support and fixing state, the open part below the holding part is blocked by the mounting surface, so that it is supported and fixed on the mounting surface. Then, it is difficult to attach and detach the piping. In order to attach and detach the pipe, it is necessary to remove the one saddle from the mounting surface and open the lower part of the holding part.

  Therefore, the band portion of the holding portion has a substantially C-shaped configuration, and the one saddle is attached to the mounting surface by expanding the open portion on the C-shaped side by utilizing the elastic deformation of the substantially C-shaped band portion. There has been proposed a technique with high workability at the time of piping that allows the piping to be attached and detached in a wet state (see Patent Document 1).
