The present invention relates to a support for releasing a space maintaining device including anchor bolts installed to be spaced apart from each other at a predetermined interval in a vertical longitudinal direction in an inner form and tie bolts having one side detachably fastened to the anchor bolts in a turn-key manner through an outer form and a bolt-shaped head provided at the other side, comprising: a bar-shaped load; a tow bar having a lifting part formed above the rod and a tow part provided below the rod and vertically moving up and down; and a ratchet wrench having a coupling part formed on one side and connected to the tow part and a clutch provided on the other side and coupled to the head. In the support, the vertical movement of the two bar is changed to a rotational movement enabling the head to rotate in one direction or in a reverse direction to release the space maintaining device. In the present invention, it is possible to collectively release at least one space maintaining device, and thus, it is possible to rapidly release a form and shorten construction time. |
