Description

S-type open double fire door structure

This creation relates to the technical field of fire door structure, especially a double-fired door structure that can open the door leaf in two directions and is easy to pass.

Many fire doors are installed in the frequent passages in the building. If the fire door is a one-way opening structure, it will cause obstacles in the reverse passage. When facing a fire emergency, the escape passage will be seriously jeopardized. Life safety is really necessary for improvement.

In addition, the general fire door will be filled with refractory material inside the door leaf, resulting in the use of the door leaf has a considerable thickness, in order to avoid interference when the door leaf opening and closing operation, the clearance gap between the door leaf and the door frame must be increased, the result will not only be reduced Sound insulation effect, and can not achieve the purpose of smoke and fire prevention, resulting in safety hazards; the above-mentioned defects, especially in the larger size of the fire door structure, such as the double-fan fire door structure, affect the use of the drama, and it is urgent to be improved.

In view of this, the present invention provides a novel S-type open double fire door structure with a two-way opening function for freedom of passage and avoidance of escape, and a shielding structure at the door gap of the door structure to ensure fire prevention. The smoke-free and fire-proof properties of the door structure eliminate the lack of thick door panels resulting in large gaps in the door structure.

In order to achieve the above-mentioned creative purpose, the S-shaped open double fire door structure of the present invention comprises: a first door and a second door in a frame, the first upper door hinge and the first lower door hinge will be first The door leaf is pivoted on the door frame so as to be rotatably opened to the outdoor side, and the second upper door hinge and the second lower door hinge pivot the second door leaf to the door frame so as to be rotatable to the indoor side. According to this arrangement, the two doors of the fire door structure can be respectively opened to the indoor side and the outside side, so as to facilitate the passage and avoid the purpose of hindering the escape route; in addition, the upper beam and the two side columns of the door frame are respectively provided with baffles, and The opening side edge of the first and second door fans are respectively provided with a blocking piece, so that when the fire door structure is closed, the gap between the side frame portion and the two door leaves of the door frame can be sealed and shielded by the baffles and the blocking piece, Ensure the performance of smoke and fire.
