Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention uses staples to install attachment bodies such as outlet boxes and conduit pipes in remote locations that are out of reach of people and are dropped into buildings. The present invention relates to a method for attaching a mounting body for locking.

(Problems to be Solved by the Invention) In concrete buildings, mounting bodies for electrical wiring such as outlet boxes and conduits are attached. Due to construction reasons, the installation of outboxes and other attachments is generally done by constructing temporary concrete frames on both sides, attaching attachments such as outletboxes to the inner surface of the temporary frames, and then pouring concrete between the temporary frames. That's what I do. Here, due to circumstances such as the temporary frames being erected at fairly narrow intervals and the mounting locations being deep and remote where people cannot reach, the common method is to install mounting bodies such as outlet boxes. I can't.

(Means for Solving the Problems) The present invention was developed primarily to easily attach attachment bodies such as outlet boxes and conduit pipes to deep and remote locations out of the reach of human hands. That is, the purpose of the present invention is to simplify the work of attaching attachment bodies such as outlet boxes and conduit pipes to remote locations, and the means for doing so is at drop-in portions of buildings. ,
This is an installation method for locking a mounting body such as an outlet box or conduit pipe using a staple in a remote location that cannot be reached by humans, and the method uses a staple that has a locking part for the mounting body at the base end. By holding the tip of the staple in a state facing the driving surface of the dropping part, moving the wedge-shaped driving part with the slanted surface, and pressing the proximal end of the staple with the slanted surface as it moves, the staple is removed. The tip is driven into the surface to be driven, and the staple is fixed to the surface with the locking part of the staple exposed, and then the mounting body is dropped and the mounting body is locked to the locking part of the staple. , is a method of attaching a mounting body using staples.

(Structure of the Invention) Hereinafter, a method for attaching an attaching body using the above-described staple will be specifically explained with reference to the drawings, but first, for convenience, the staple driving device and the staple will be explained.

In FIG. 1, a frame 1 is used to house various parts, and in the case of the example shown in the drawing, it is shaped like a long rectangular tube and has an insertion hole 2 at its upper end.
