Description

A fire pin device installed on a fire door or frame of a fire door

The present invention relates to a fire prevention pin device installed on a fire door or a fire door frame, and more particularly, by being installed on a fire door or fire door frame to fasten the fire door and the fire door frame, through the space generated by the warping of the fire door or fire door frame when a fire occurs. It relates to a fire door or fire pin device installed in a fire door frame implemented to prevent the leakage of flames or smoke.

A fire fin is a fire protection component applied to fire doors such as general and colored doors. It interacts with the pre-fixed protrusion pin on the door or on the door frame, performing a crime prevention function and preventing the door from being twisted in case of a fire.

That is, when the fire door is provided with the fire pin, when the fire door is closed, the protruding pin installed on the door frame is inserted and coupled to the fire door's fire pin, thereby performing a crime prevention function.

In addition, if several fire fins are installed, it is advantageous because the fire door does not twist even if a fire occurs.

On the other hand, such a fire fin is usually made of a metal material, and is welded to the fire door. That is, the fire pin can be installed by aligning the fire pin with the pin hole formed in the fire door and adjusting the position, and then welding the fire pin and the fire door.

In particular, in the case of a fire door and a fire door frame in which the fire door is installed, distortion does not easily occur even when a fire occurs in the area where the hinge is installed due to the fastening force of the hinge and the area where the handle is installed by the fastening force of the handle clasp. However, in the case of other corners of the fire door, there is not enough fastening force, so it is easily twisted in the event of a fire, so there is a problem that flames and smoke can leak through the space generated by the twist.

On the other hand, the above-mentioned background art is technical information that the inventor possessed for the purpose of derivation of the present invention or acquired during the derivation process of the present invention, and it cannot be said that it is necessarily known technology disclosed to the general public before the filing of the present invention. .
