In this embodiment, in order to install the accommodating groove 1, a wall opening needs to be formed in the wall body, an avoiding channel is formed in the door frame 8, and the accommodating groove 1 entirely penetrates through the door frame 8, but actually, since the length of the door frame 8 in the extending direction along the fixed rail is smaller than the length of the accommodating groove 1 in the extending direction, only a part of the accommodating groove 1 penetrates through the door frame 8. In other embodiments, the length of the doorframe in the extending direction of the fixing rail may be increased so that the entire receiving groove penetrates through the doorframe. In the above two embodiments, the accommodating groove penetrates through the door frame, and in other embodiments, the width of the door frame in the direction perpendicular to the extending direction of the fixing rail may be increased, so that the entire accommodating groove may be disposed in the door frame, and at this time, the accommodating groove may be considered to be disposed on the inner side surface of the door frame. It should be noted that the receiving groove is used to provide a receiving space for the butt-joint rail and the linear driving mechanism, and based on this concept, in other embodiments, actually, the receiving groove is formed without specially processing the components such as the box body, and the like, and only the hole is formed in the door frame and the wall.
In this embodiment, prevent that fire door is the vertical hinged door, moreover, the holding tank is located the intermediate position of two door plants, and the horizontal center of holding tank equals with the distance of two articulated axes promptly. The purpose of design like this, prevent that fire door need not open completely, only need open certain angle and just can supply the butt joint track to put into, moreover, the horizontal center of holding tank equals with the distance of two articulated axes, and the angle that needs open is minimum. In other embodiments, the receiving groove may be offset at one of the door panels. Or, in other embodiments, the fireproof door can be opened in the form of a sliding door, and the accommodating groove can be located at the top of the door frame and also can be located on the horizontal side of the door frame, i.e., the butt joint rail can move up and down and can also move horizontally. Of course, because the underground pipe gallery or the tunnel is small in size, the vertical hinged door is the optimal mode, and after the sliding door is used, the section size through which the sliding door can pass after being opened is small.
