The present invention relates to a non-directional smoke control damper. The non-directional smoke control damper comprises: a support; a rotation unit, slide units coupled to the front and rear sides of the support and having at least one slide groove; a movable unit; a supporting unit; a shaft unit; and a plurality of panels formed with a bending unit coupled to the shaft unit to move upward and downward in a step form according to the upward and downward movement of the supporting unit. The supporting unit formed in an X-shape is easily moved upward and downward through the rotation unit including a first screw part and a second screw part, and a panel formed with multiple steps is easily moved upward and downward, so air or smoke is properly circulated or blocked through a space formed between the panels. Therefore, the non-directional smoke control damper can reduce fire damage. The supporting unit has a simple structure to be easily operated, and the manufacturing process is simplified to reduce manufacturing costs, and thus the non-directional smoke control damper can be economical. |
