Description

DETAILED DESCRIPTION OF THE INVENTION The present invention is a method for remotely attaching a locking device, which is integrated with or separate from a buried object such as an outlet box or a switch box, to a position of a temporary concrete frame that is out of reach of people. .

In concrete buildings, buried objects such as outlet boxes and switch boxes for electrical wiring are buried. This buried body is buried, for example, by erecting temporary concrete frames in a side-by-side state, attaching the buried bodies to the inner surface of the temporary frames, and then pouring ready-mixed concrete into the temporary frames. Here, since the intervals between the temporary concrete frames are generally quite narrow and the installation position of the buried object is quite far away and out of reach of people, it is extremely difficult to attach the buried object using normal methods. Due to these circumstances, the inventor of the present invention filed a patent application in 1983 as a result of intensive research.
We have recently developed a device according to No. 130773 (Japanese Unexamined Patent Publication No. 58-34764). This device is provided with a rotary drive shaft that extends to a distant position, converts the rotation of this rotary drive shaft into a direction that intersects with the longitudinal direction, and thereby attaches screws to a temporary concrete frame.
After installing the screws, the worker lowers the buried object from the end of the temporary concrete frame and hooks the buried object onto the exposed portion of the screw.

The above-mentioned patent application No. 130773 (1982)
According to the device according to Publication No. 34764), screws can be installed extremely easily even when the interval between concrete temporary frames is quite narrow and the installation location is far away. The method according to the present invention is based on the patent application filed in 1983.
This was developed as part of the device related to No. 130773 (Japanese Unexamined Patent Publication No. 58-34764), and cleverly utilizes the method of remotely attaching screws to the concrete temporary frame at a remote location that cannot be reached by humans. This is a method for remotely attaching a locking device. The present invention is a method for attaching a locking device that is integral with or separate from a buried object and has a hole, and the present invention provides a method for attaching a locking device that is integral with or separate from a buried object and has a hole.
