[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION The present invention relates to a hand used for supporting a handrail pipe for supporting a worker walking on a steel frame of a building or the like at a building site such as a building. The present invention relates to a support pipe for attaching a sliding pipe.

[0002]

2. Description of the Related Art Conventionally, as means for ensuring the safety of workers walking on a steel frame or the like of a building,
A rope or a wire called a master rope is horizontally stretched between the upper ends of the columns supported by the steel frame or the like, and a free end locking device of a safety belt worn by a worker is engaged with the master rope. However, in order to further improve safety, it has been considered to install a handrail pipe (single pipe) instead of the master rope.

It is a matter of course that a conventional main column support is also known in which a pipe clamp for mounting a handrail pipe is mounted on the front surface of the column. In such a conventional column, the pipe clamp is used. Since the direction of the handrail pipe to be installed is limited to a fixed direction parallel to the steel frame to which the support is attached, for example, the handrail pipe is laid in a polygonal shape along the arc-shaped part of the building, or the corner of the building When the handrail pipes are erected at right angles along the part, the struts must be independently arranged at each end of each handrail pipe, and the number of struts is simply increased, which is uneconomical. In addition, since the adjacent handrail pipes are not connected to each other, the strength of the handrail as a whole is reduced, and there is a problem in terms of safety.
