The present invention provides a gang form safety device capable of preventing accidents occurred when a gang form for the construction of an outer wall of an apartment house is used, being installed in advance when the gang form is manufactured in a factory instead of being installed in the field, and automatically returning a head of a body bolt protruding forward to its original position in the disassembly of the gang form to seal the head of the body bolt. The gang form safety device comprises: a fixed bracket part installed on a front surface of a vertical gang form material; a protrusion sill formed on the fixed bracket part; a rotary shaft insertion hole formed on the protrusion sill to insert a rotary shaft; a rotary body coupled to the rotary shaft to restrict the rotation; an elastic body fitted in an elastic body insertion groove of the rotary body and wound on the rotary shaft; a turning operation pin inserted into a turning operation pin insertion hole of the rotary body; a cover coupled to the turning operation pin to restrict the rotation; an operation knob coupled to the turning operation pin to restrict the rotation; and a safety ring coupled to a leg insertion hole of the operation knob. |
