Elevator core structure that can be pre-constructed and method for preconstructing elevator core using same

An elevator core structure comprising:

• an elevator frame (120) separated from a main frame (110) and extending in a longitudinal direction of the main frame (110);
• a guide frame (130) formed on an inner surface of the elevator frame (120);
• an elevator unit (10) inserted to the elevator frame 120);
• a front room (200) formed in the main frame (110), wherein the front room (200) includes an elevator hoistway (210) configured to connect the elevator unit (10) and the front room (200);
• and
• a sealing part (300) disposed between the elevator hoistway (210) and the elevator unit (10),
• wherein the sealing part (300) includes a horizontal beam (310) extending in a width direction (a) of the elevator unit (10);
• and a bracket (320) installed below the horizontal beam (310) and coupled to the main frame (110) to support the horizontal beam (310),
• wherein the bracket (320) includes an angle (321) coupled with the main frame (110);
• and a movable plate (322) disposed on the angle (321) and moving in a thickness direction (b) of the horizontal beam (310), and
• wherein the horizontal beam (310) includes a H-beam (311) disposed on the moveable plate (322);
• and a concrete member (312) formed by on-site pouring into a space between the H-beam (311) and the main frame (110).
