A two-way door with a two-way door closer structure comprises a three-in-one framework having two frames and one leaf, thus a unique door cheek structure which in fact features one frame and two leaves is formed, leading to flexible opening directions. Through the use of a door-in-door structure of the two-way door, two solid doors, i.e. a large door (A) and a small door (B) contained in the large door (A), are formed. Particularly, a two-way door closer (7) is used for controlling the functions of the two door leaves that are opened in a unidirectional manner. The door cheek can be opened and closed at will in a two-way manner, and the most flexible function that people push the door in any direction for escape and close the door for fire prevention can be achieved. |
