Gangform device constructed for wall and constructing method this using

PURPOSE: A form system for constructing the wall of a building and a construction method using the same are provided to enable the continuous construction of walls by moving the form system to a construction layer of a building. CONSTITUTION: A form system for constructing the wall of a building comprises a form panel(10), a rail assembly(20), and a rail propulsion device(30). The form panel has a specific area to form a wall form(3). Multiple vertical members(11) are installed on the front surface of the form panel. The rail assembly is connected to the form panel and fixes the form panel to a construction layer. The rail propulsion device pulls up the rail assembly so that the form panel can be located at the construction layer.
