PURPOSE: A bottom support of a form is provided to fix a bottom plate without using nails or with a reduced number of nails by employing anchoring wedges. CONSTITUTION: A bottom support of a form comprises a bottom plate(1) which is fixed to concrete bottom, a length-controllable support bar(2) which is coupled to the bottom plate, a coupler which is installed on the top of the support bar and coupled with a form, vertical blades(4) which are installed on two sides of the bottom plate, and wedges(5) which are installed on the underside of the vertical blades. The wedges comprise a vertical portion(51) on the front side and an inclined portion(52) on the rear side in order to reduce slip due to a push force.
