JP2007276095A - Auxiliary tool for driving post-driving anchor into upper part - Google Patents

Abstract

<P>PROBLEM TO BE SOLVED: To solve the problem wherein it is hard to drive a heavy hammer drill upward with the sufficient man power, and it is dangerous for eyes to receive dust and dirt for a work in the high place with a face directed upward. <P>SOLUTION: An auxiliary tool is fitted with the hammer drill for making the work the same as the work performed on the floor surface, which is safe. Working efficiency is thereby remarkably improved, and above all, the work can be performed by the man power smaller than ever before. <P>COPYRIGHT: (C)2008,JPO&INPIT

Description

The present invention relates to an auxiliary device for a post-fixed anchor used at a construction site or the like.

As shown in FIG. 3, the conventional post anchor construction method is ascending to a stepladder / aerial work platform and working with great force while checking the upper part.

However, according to the above technique, it is difficult to work up and down because it is necessary to apply sufficient force to raise and lower the altitude, especially the upper part.
Therefore, an object of the present invention is to provide an instrument that does not require ascending and descending to a high place and that reduces the force applied to the work.

In order to solve the above problems, the first invention is an apparatus characterized in that an auxiliary instrument is attached to a hammer drill.
Further, the second invention is an apparatus characterized in that a slide type operation unit is attached during the upper work.

  According to the first invention or the second invention, workability is remarkably improved and safety is secured by attaching the auxiliary tool to the hammer drill.

One embodiment of the present invention is shown in FIG.
The hammer drill is fixed at the parts (1) and (2), and the fixed part to the floor with the part (3) to be expanded and contracted is a pipe (7) that is slightly smaller with the pipe (7). Is configured to slide by pressing the operation portion (9).

"Effect of the embodiment"
According to this embodiment, as shown in FIG. 1, the drill is fixed to the portion {circle around (1)} and received at the portion {circle around (2)}.
At this time, the anchor embedding length can be adjusted by the adjustment portion (3).
(7) Place the fixed pipe on the floor and 4) Adjust the length of the slide pipe. The length can also be adjusted at (5) and (6). When the device is set, turn on the switch (8) and push the part (9) down to open the anchor hole with the minimum force and work safely.

"Other embodiments"
In the embodiment of FIG. 1, the operation portion is a handle type that applies a vertical force as shown in FIG. 2, but may be a rotary type or the like.

It is an elevation view of the present invention. It is an enlarged view of an operation part. It is drawing which shows a prior art.
