  The conventional fixtures as described above are often made of resin. From the viewpoint of securing the strength, the tube contact portion 921 along the outer peripheral surface of the tube, the fixing portion 922 that contacts the floor surface, and the like are about 3 to 5 mm. It was formed with a certain thickness, and was thicker than a thin metal fixture.

  In addition, a screw hole 14 is provided in the fixing part of the fixing tool, and the fixing part is formed so that a work space of about 6 to 10 mm can be secured around the screw hole in consideration of workability when fixing the screw. The width of about 6 to 8 mm is provided outside the screw hole 14 because it has to do with fixing strength. For this reason, the fixture 92 generally has a width of about 50 mm or more in a direction orthogonal to the tube axis.

  However, in the sheath pipe header construction method, the connection ports of the header are provided, for example, at intervals of about 50 mm, and a plurality of branch pipes and sheath pipes 91 are connected to this, so the interval between the tubes is about 28 to 32 mm. And very narrow. Since the fixture 92 having the thickness and size as described above must be arranged in such a narrow space and the pipe 91 connected to the connection port of the header 9 must be fixed, as shown in FIG. In order to avoid interference between the fixtures 92, the fixtures 92 to be fixed are shifted and fixed alternately in the tube axis direction, or the intervals between the pipes at the fixing locations of the pipes are increased as shown in FIG. I had to.

  If they are fixed as shown in these figures, it is necessary to carry out the screw fixing work of the fixing tool 92 at two adjacent positions, or to secure a wide piping space corresponding to increasing the interval between the pipes. There was a problem that workability was inferior and the fit was poor.

  Therefore, the present invention has been made in view of the above problems, and provides a pipe fixing tool that can fit and stably fix a pipe to the floor surface even when the pipe interval is narrow. .

An adjustment piece having substantially the same dimensions as the cutout portion is formed on the other fixing plate portion provided at the end portion through a thin connecting portion. It is characterized in that it can be bent or separated .

  According to this configuration, the fixing plate part of the pipe fixing tool is overlapped with the fixing plate part of another pipe fixing tool arranged adjacent to the pipe fixing tool so that the screw holes are continuous, and both of them are collectively placed on the floor surface. Therefore, even when the space for fixing the pipe is narrow, the pipe can be fixed with good fit without increasing the pipe interval.

Moreover, according to the said structure, when arrange | positioning piping fixing tools adjacently, while cutting off an adjustment piece in a connection part and inserting one fixing plate part of another piping fixing tool into a notch part, it can be superimposed. When not arranged adjacent to each other, the adjustment piece is accommodated in the cutout portion, so that the cutout portion can be filled and the fixing plate portion can be stably fixed to the floor surface.

Further, the present invention provides the above pipe fixture, wherein the adjustment piece has a fixing screw hole, and when the adjustment piece is bent or separated and placed in the cutout portion, the other fixing plate portion The screw hole and the screw hole of the adjustment piece overlap each other, and when the fixing plate portion of another pipe fixing tool is inserted into the notch portion, the screw holes of both fixing plate portions are configured to overlap each other. Is preferred .
