EXTENDING SYSTEM FOR WALL-TYPE STRUCTURAL APARTMENT AND METHOD FOR CONSTRUCTING THE SAME

An extension system for a wall-type structure of a building is provided to integrate the existing wall type structure with an extension effectively by extending a plane of the existing wall type structure of a building and designing an extension in a wall-type structure, to shorten a period of construction by using a steel deck plate instead of a horizontal form and to increase the strength of an extension by using a reinforcement device. The extension system(1) for a wall-type structure of a building contains a floor slab(10) for an extension joined with the existing floor slab, a steel deck plate(20) supported to the bottom of the slab and used as substitute for a horizontal form in the construction of the floor slab and joined integrally after construction, a wall(30) for an extension joined with the floor slab as a vertical form(40) supporting the steel deck plate, and a reinforcement device constructed to enhance the strength of the slab, the wall and the deck plate and composed of reinforcing bars(50a) coupled through the wall, the slab and the deck plate and a reinforcing anchor(50b) which contains a stud bolt(50b1) integrated with the wall and a reinforcing angle(50b2) inserted between the vertical form and the deck plate.
