UPWARD-MOVING TYPE FORMWORK DEVICE FOR LARGE-SIZE CONCRETE STRUCTURE CONSTRUCTION

摘要

PURPOSE:To easily and quickly move an upwardly moving type formwork device to a given position by a method in which a frame fixer is screwed tight with an anchor bolt, the middle of a horizontal frame is supported, and the formwork device is upwardly moved through a coupler by means of a vertically movable frame. CONSTITUTION:Formwork devices 3 are sideways set and an upper traveling wheel 7 and a rotator 8 for detaching dummy bolt and clamping C-bolt are provided for the outside of the devices 3. A frame fixer and a lower traveling wheel 12 to be touched by concrete face are provided for both sides of the lower part of a horizontal frame 6. A rotator 13 for detaching C-bolt and a jack 15 for supporting the frame 6 are provided for both sides of the middle of the frame 6. The formwork devices can thus be easily, safely, and quickly moved upward by mechanical power.
