Description

[Detailed Description of the Invention] [Object of the Invention] Industrial field of application The present invention has a clamp part that can be easily and directly clamped to an anchor bolt of a steel frame or ceiling of a building, and is also used for piping such as cooling and heating equipment. The present invention relates to a pipe support that is easily fixed.

2. Description of the Related Art Conventionally, in buildings and the like, air-conditioning pipes used for air-conditioning equipment or indoor pipes such as water pipes are generally attached to anchor bolts or other mounting members that are driven into walls such as ceilings at predetermined intervals. On the other hand, the mounting base of the pipe fixing device is screwed, and then the predetermined portion of the pipe is crowned with a regular circular clamp band in which a strip-shaped metal plate is made to approximately match the cross-sectional shape of the pipe, and both ends of the clamp band Are fixed to the mounting base with bolts, and the tube row is fixed.

However, in such a piping method, the mounting base of the pipe fixing device must be screwed to a mounting member such as an anchor bolt. For example, in the case of an anchor bolt that does not have a fixed length, the anchor It is necessary to cut the end of the bolt to form a certain height, and screw the mounting base to the end to adjust the vertical position of the pipe fixing device, and one for each anchor bolt. It has a drawback that only the pipe fixing device can be attached.

Also, when supporting the pipe on the pipe fixing device, it is necessary to cover the predetermined part of the pipe with a clamp band and then tighten the bolts one by one, especially the pipe is hung from the ceiling If you want to
Since it is a work of bolting the clamp band that covers the predetermined part of the pipe with both hands overhead, work fatigue is significant and it is very inefficient, so the time consumed is long and the work This has the drawback that the cost per person for each hour rises and that one worker cannot easily finish the work.

Further, even when using a steel frame member or the like to support the pipe, it is necessary to form a mounting hole in the steel frame member or the like and fix the pipe fixing device with a bolt or the like to the mounting hole. The workability was extremely poor.

The problem to be solved by the present invention is that the present invention reduces the time and labor required for the piping of cooling and heating equipment, etc. to improve the work efficiency and work time, and reduce the cost per hour for workers. It is intended to provide the pipe support tool.

[Constitution of device]

Means for Solving the Problems In view of the above problems, the present invention forms a fixed holding wall by continuously bending from one side of a flat base body at a right angle, and a back surface is provided at a position opposite to the fixed holding wall.
