[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an anchor base driving tool for driving an anchor base such as an anchor bolt or an anchor pin into a structure such as a ceiling or a wall.

[0002]

2. Description of the Related Art Conventionally, when anchor materials such as anchor bolts and anchor pins are driven into a structure such as a ceiling or a wall,
I was hitting it with a hammer.

[0003]

However, in the above-described conventional anchor base material driving method, it is necessary to approach a structure such as a ceiling or a wall to be driven, so that the scaffolding is bad and the wall or ceiling cannot be approached. There has been a problem that the work efficiency is very poor because the driving work in a place with a distance has to be performed by using a workbench or scaffolding. The present invention has been made in view of such circumstances, and an anchor base driving tool capable of efficiently driving an anchor base such as an anchor bolt or an anchor pin without approaching a structure such as a ceiling or a wall. The purpose is to provide.

[0004]

A method according to the above-mentioned object.
The anchor base driving tool described above is an anchor base driving tool having a guide pipe and a driving rod slidably moving in the guide pipe. A mounting part provided at the end,
It is configured to have a driving pin slidably penetrating the mounting portion, and driving switching means provided on the guide pipe or the driving rod for switching driving of the driving rod to drive the guide pipe or the driving pin. .
An anchor base driving tool according to a second aspect of the present invention is the anchor base driving tool according to the first aspect, wherein the mounting portion is configured to be replaceably provided on the guide pipe corresponding to the anchor base material. There is. The anchor base driving tool according to claim 3 is the anchor base driving tool according to claim 1 or 2, wherein the mounting portion is detachably provided with an attachment corresponding to the anchor base material. Has been done.

[0005]

In the anchor base driving tool according to claim 1, an anchor base such as an anchor bolt or an anchor pin is mounted on a mounting portion provided at an end portion of the guide pipe, and the driving switching means is driven into the guide pipe. The anchor base material is inserted into a mounting hole that has been drilled in the ceiling, wall, or other planned location for driving, and the driving rod is slid by moving inside the guide pipe and colliding with the guide pipe. Hit it. The anchor base material is driven into the attachment hole by driving the guide pipe. Then, after driving the anchor base material to a predetermined depth, the driving switching means is switched to the driving pin and the driving rod is slid in the same manner as described above to drive the driving pin into the anchor base. Of the expansion base member, the expansion pin expands the end portion of the anchor base material, and the side surface thereof bites into the attachment hole. Finally, the attachment of the anchor base material and the attachment portion is released, and the work is efficiently completed without approaching the structure such as the ceiling or the wall.

In the anchor base driving tool according to the second aspect, since the mounting portion provided on the guide pipe can be replaced, the anchor base such as anchor bolts and anchor pins having different sizes and types can be used. Can be used in the same manner as in the anchor base driving tool described in claim 1. In the anchor base driving tool according to claim 3, an attachment corresponding to the size or type of the anchor base material is detachably provided on the mounting portion of the anchor base driving tool according to claim 1 or 2. The anchor base material can be mounted and used in the same manner as the anchor base material driving tool according to claim 1 or 2 without changing the mounting part.
