It is attached by tightening.
(See FIGS. 9, 10, and 11)

However, the above-described conventional elbow cover for piping is, as described above, the two lower end portions 103a and 103b of each of the sector mounting plates 102a and 102b are bent and tightened with pliers or the like, and both pipes of the elbow portion 15 are connected. It is attached in a state of tightly adhering to the surroundings, but the fitting work is performed in various places with different piping conditions such as buildings, and in many cases with an unreasonable posture, so considerable skill and physical strength are required. Therefore, there is a big problem that the mounting accuracy varies depending on the skill of the worker, especially in the recent times when it is difficult to secure skilled workers, and it takes much time and labor for the mounting work, and it is extremely inefficient. There was a problem that many complaints of poor mounting occurred.
