Description

The present invention relates to the technical field of a temporary holding structure and a temporary holding method for an opening/closing machine in an architectural shutter device provided at an entrance/exit of a building such as a building, an opening of a pit section, a square section, etc.

Today, architectural shutter devices are sometimes installed in buildings such as buildings to open and close openings such as entrances and exits, and when such shutter devices are assembled on site, there is a Various components and devices are attached, such as left and right brackets that are attached to the frame above the shutter curtain, a winding shaft around which the shutter curtain is wound, and an opening/closing machine for rotationally driving the winding shaft.
In such devices, the on-site assembly of the shutter device to the frame is usually done by attaching a bracket to the frame, attaching the winding shaft to the bracket, and then attaching the opening/closing machine to one of the brackets. It is common to work like this. When installing such a switch, or when performing maintenance work such as replacing the switch when it malfunctions or malfunctions, the individual switch that separates from the bracket (comes off) May handle machines. However, the switchgear is a heavy machine with heavy objects such as an electric motor installed inside, and the work to replace such a heavy switchgear is carried out in a narrow ceiling space above the opening. In the space, the worker is required to carry out the attachment/detachment work while supporting (holding) the heavy switchgear, which not only reduces work efficiency but also places a heavy burden on the worker. Particularly during maintenance work, the parts and equipment such as the switchgear are placed in a narrow upper space (behind the ceiling) hidden by the ceiling panel, so the switchgear should not be operated in such a place. There is a problem in that performing maintenance work is much more difficult and less efficient than when installing a switch when installing a new shutter device before the ceiling board is installed. .
Therefore, it is known that a bracket on the side to which the opening/closing machine is attached is provided with a support member for constantly supporting the opening/closing machine (see, for example, Patent Documents 1 and 2).
