IN-BAR STAFF FIXING APPRATUS FOR LEVELING

摘要

The purpose of the present invention is to provide an apparatus for fixing an in-bar staff for precise leveling, in fixing and installing an in-bar staff used as a staff exclusively for digital leveler, capable of performing stable precise leveling work by maintaining a firm fixed state even when a ground for fixing an in-bar staff is not rigid, capable of accurately maintaining a vertical state by finely tuning the slope and capable of obtaining precise and accurate data when precise leveling by minimally decreasing a vibration delivered to the in-bar staff even when the vibration is generated to the ground. The apparatus for fixing an in-bar staff for precise leveling of the present invention includes: a central body for having an installation groove for raising and installing the in-bar staff in the vertical direction; a fixing body surrounding the central body to be located in the center; a plurality of elastic springs elastically installed in between the central body and fixing body; first and second fixing tools prepared in both sides of the fixing body; a fixing rod for inserting into the ground surface through the second fixing tool; a vertical indicator for confirming the vertical state of the in-bar staff; and first to fourth control screws for controlling the slope by pressurizing the left and right sides of the in-bar staff.
