た。 Conventionally, when installing a ceiling inspection port on the ceiling,
It was difficult to align (level) the ceiling surface and the bottom edge of the outer frame, and required a lot of skill and specialized skills. Under these circumstances, a method has been desired that would allow even non-experts to easily align the ceiling surface and the lower end of the outer frame.
また、天井点検口を天井に取付ける方法は、先
ず、天井板を軽量鉄骨下地に張設してから、天井
点検口用の開口を設け、天井点検口をはめ込み天
井に吊持されていた。 In addition, the method for attaching a ceiling inspection port to the ceiling is to first install a ceiling board on a lightweight steel frame base, then create an opening for the ceiling inspection port, fit the ceiling inspection port, and suspend it from the ceiling.
ところが、一般に天井板を張設する工程に従事

能になる。 However, the workers who are engaged in the process of installing ceiling panels and the workers who are engaged in the process of installing ceiling inspection ports are generally different people, so it is not possible to wait until the ceiling panels are installed and then install the ceiling inspection port. It was inconvenient and inefficient. If a ceiling inspection port can be installed depending on the construction status of the ceiling board, that is, before or after installing the ceiling board, the work process can be shortened.
