Description
BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a door having improved fire resistance and a fire door unit including the same, and more particularly, to a door that can be used in the fields of construction, interior decoration, and disaster prevention.
A fire door unit refers to a door installed in a building to prevent a fire from spreading. Fireproof doors shall meet the Fireproof Door Standard requirements of the Ministry of Land Transport and Public Notice No. 2015-212. Article 5 of this Notice stipulates fireproof door fireproof test methods and test methods. The fireproof door test method according to these regulations must have fireproof performance for one hour at 980 ℃.
In order to achieve fire resistance in fire environments, fireproofing must be performed to prevent ducts that can not pass gases such as toxic gases and to prevent deformation (bending phenomenon) that can occur in fire conditions.
1 is a view showing a configuration of a conventional fire door unit. In FIG. 1, a main heat insulating material M 1 is filled between two spaced plates P 1 and P 2 . The internal stiffener (R) prevents the fire door from being bent by heat during a fire to prevent it from being detached from the door frame.
In order to secure the inner reinforcement (R) to plate (P 2), it is arranged as shown in Figure 1 so as to face the internal reinforcement (R) and one side of the plate (P 2), and then, the internal reinforcement (R) and the plate (P 2 ). However, since the space between the plates P 1 and P 2 is narrow, it is not easy to weld the internal stiffener R to the plate P 2 , and the operation time is also long.
An object of the present invention is to provide a door having excellent ductility and fire resistance and being easy to manufacture and a fire door unit including the same.
The fire door unit according to an embodiment of the present invention includes a
Preferably, the
The door according to the present invention and the fire door unit having the same according to the present invention do not require a process for welding the internal reinforcing member to the door and are excellent in fire resistance to prevent deformation (warping) of the fire door due to fire through a simple bending process. Further, since the space of the door and the door frame is sealed by using the flame-retardant packing member, it is possible to secure the ductility to block the spread of the noxious gas and the flame.
