A hanging rod (3) to which a hanger (2) is attached is hung vertically, and a support member (4) made of shaped steel or the like is engaged with the hanger (2), and a field connected to the support member (4) is connected to the hanger (2). Edge member (5
) to attach the ceiling material (6) to a sky-like ceiling, as a preparatory work for construction, attach the hanger (2) to the hanging rod (3) for suspending the ceiling. Usually, as shown in Figure 2, a threaded rod (~) of the required length to be used as a hanging rod is passed through the hole in the mounting plate (7) of the hanger (2) and screwed onto the threaded rod (4). The hanger (2) is attached to a predetermined position on the threaded rod (c) by sandwiching the mounting plate (7) from both sides with the two jointed oaks (B, ) (B2).

付作業に多大な労力を要するものである。Conventionally, the hanger installation work, including the screwing of the nut onto the threaded rod (A), has been done entirely manually, which is extremely inefficient and requires a great deal of labor, and an improvement is desired. In other words, the length of the threaded rod used as a hanging rod is generally 30c.
The length from the end of the threaded rod to the hanger installation position, that is, the screwing distance of the nut, is usually about 100 to 150 mm or more, which is quite long, although it varies depending on the size of the screw during the installation work. Screwing nuts onto rods is extremely troublesome and time-consuming, especially in large ceilings of large buildings where there are hundreds of hanging rods.
Since the number of hangers is several thousand, a great deal of labor is required to attach the hangers, including screwing the nuts together.

とから、実用化には至っていない。In addition, in order to streamline the screwing of the nut onto the threaded rod in the above installation work, a receiving part into which a nut (a square nut such as a hexagonal nut) fits is provided at the tip of the cylindrical body that is rotationally driven by the motor. - A method in which a nut is fitted into this receiving part and a threaded rod is pushed into it while rotating the cylindrical body with the nut and screwed together, or a funnel-shaped receiving part is provided at the tip of the rotating cylindrical body, It is not inconceivable that the rotating receiver could be screwed into place by pressing a nut previously screwed onto the tip of the threaded rod, but in the former case, each time the - nut is screwed. The rotation of the cylindrical body must be stopped each time the nut is inserted, and in the latter case, the nut must be preliminarily screwed onto the tip of the threaded rod, which takes time and effort. However, it has not been put into practical use because there is little hope of achieving the same level of efficiency that would otherwise result.
