Abstract

Disclosed are a construction method of a door frame with an integrated form and a device thereof. The construction device of a door frame with an integrated form comprises: form panels arranged to face each other to have intervals corresponding to the width of a concrete structure; a finishing unit provided to form opening parts when removed from the form panels by cutting and forming a portion of the form panels; a fixed unit fixed on an outer wall of the form panels, and provided to allow penetration units to communicate with the opening parts; and a form connection unit passing through the opening parts formed by removing the finishing unit from the form panels and the penetration units overlapped with the opening parts to connect the neighboring form panels to each other. According to the present invention, construction periods or processes of carpentry such as door frame construction can be reduced, and the strength of a bearing wall can be increased by additionally securing structural resisting force in place of reinforcing bars on the end of the wall.
