More Information
Summary:The utility model provides an improved open and biparting fire door of a building. The improved fire door is characterized in that a door shield which limit the opening of a single door leaf and has a length smaller than or equal to the length of the single door leaf is arranged on each face of a doorframe; and each door leaf is provided with a door closer which can keep the closure of the door leaf. The split biparting door is respectively caused to be unidirectionally opened in different directions, so that when any side of the door is on fire, people can effectively escape from the door; and each door leaf is ensured to be throughout in a closure state up to the standard, thereby overcoming the defect of the prior two-way escaping fire door.
