PURPOSE: An early stripping method of a horizontal member lower mold form such as a beam and a slab is provided to reduce materials required for mold form works and a term of works by separating a sub-mold form of a horizontal stem such as a beam and a slab. CONSTITUTION: An early stripping method of a horizontal member sub-mold form such as a beam and a slab comprises the steps of: if the compressive strength of concrete extends to over the value a structure engineer requires after concreting in reinforcement concrete works, disjoining a beam-side mold form(14); installing a primary timbering(20) on each mold form adjacent over one of the bottom of a beam; dismantling the remained mold form except the mold form supported by the primary timbering, an initial timbering(10), a sleeper and a bridging joist(12); installing a secondary timbering(30) on the beam lower concrete surface exposed by dismantling a mold form; if the installation of the secondary timbering is completed, detaching a mold form(13) supported by the primary timbering and the primary timbering; and dismantling the secondary timbering if the standard design compressive strength of concrete is revealed.
