<p>PURPOSE: To facilitate working by fixing the body part of a connecting pipe to the pipe end inner surface of a handle beam by an inner caulking means, fixing a support plate to the connecting pipe, and mounting the support plate onto a wall surface to fix the handle beam. CONSTITUTION: The pipe end part 11 of a handle beam 1 is connected to a connecting pipe 2 by an inner caulking means using a collet tool. A support plate 8 is fixed to the pipe end part 11 by screwing the screw 71 of a bolt 7 to the screw 21 of the connecting pipe 2. The support plate 8 is mounted on a wall surface W through a set screw 81 to fix the handle beam 1 onto. the wall surface W. Thus, the working can be easily performed regardless of the thickness of the pipe end part, and even when the handle beam is coated with resin, the connecting pipe can be mounted without damaging the handle beam surface.</p> |
