The support pipe is installed to be coupled.

However, the fall prevention net spread on the lower support pipe prevents workers or pedestrians from falling from the building to the ground and injuries to workers or pedestrians. However, the fall prevention net is inclined 20 to 30 degrees outward from the outer wall of the building. When a worker falls, it can be rolled once or twice in a fall prevention network or bounced toward the outer wall of a building, causing confusion or injury, and moreover, if a person falls in an upper support pipe, a fatal accident such as fracture or spinal cord injury occurs.

In addition, in order to install such a fall prevention network, the installer fixes the bracket to the railing or wall of the building, and the lower support pipe is inclinedly coupled to the fixed bracket by a clamp, and then moved to the outside of the building along the lower support pipe to move the fall prevention net. There is a serious problem that the fall accident frequently occurs due to carelessness in the process of installing at the end of the lower support pipe.

In addition, the lower support pipe has a problem in that it takes a lot of labor and time since the steel pipe needs to go through several steps of reassembling after being assembled with two or more steel pipes.

Thus, in order to solve this problem, the technology described in JP 10-2005-49440 as shown in Figure 1 has been developed, the technical feature of the support bar 1 is that the start end and end are maintained at a constant interval Each reinforcing member 14, 14 ′, 14 ″ is configured to be coupled between two long parallel steel pipes 11, 11 ′, wherein the reinforcing member 14 is a steel pipe 11.
