Claims

[Scope of utility model registration request]

(1) A port tightening/loosening unit is mounted on the horizontal frame of the device above each tightening bolt that tightens the joint flanges of the vertically divided formwork, and the bolt is rotated by a drive mechanism. The shaft of the tightening/loosening unit and the spindle are connected by a connecting member, and a socket provided on the spindle that can only move up and down within a certain range is elastically biased downward, and the horizontal frame of this device is A tightening/loosening device for a concrete column forming formwork tightening holt configured to be able to move up and down.

(2) Concrete column shaping form tightening according to claim 1 of the utility model registration claim, characterized in that the connecting member is a flexible joint whose head oscillation is regulated within a certain range. Bolt tightening/loosening device.
