Abstract

The present invention relates to a wall mold construction method with improved constructability and a mold structure thereof. The wall mold construction method with improved constructability constructs an outer mold provided on the bottom and having wall embedding and reinforcing parts, and an inner mold distanced from the outer mold and having a space part in which concrete is poured and cured. The wall mold construction method comprises: an outer mold construction step in which an outer mold in which wall embedding and reinforcing parts are coupled to an outer sheathing board by couplers is supported by a reinforcing frame; and an inner mold construction step in which an inner mold is formed by fittingly coupling couplers, coupled to an inner sheathing board, to the wall embedding and reinforcing parts coupled to the outer sheathing board. Therefore, the wall mold construction method allows the wall embedding and reinforcing parts to be coupled to the outer mold by two couplers facing each other, thereby preventing separation of the wall embedding and reinforcing parts, facilitating easier construction, and preventing separation thereof in a reverse direction after the coupling.
