Mounting means (30) for coupling the heat expansion sheet (20) to the frame (10);

(U), wherein the unit (U)

The frame 10 is made of a magnetic material to be attached to a door which is a compliment.

Here, the frame 10 has a plate-like structure, and is made of a magnetic material so that it can be detachably attached to the door 1, which is a material of a peculiar material such as metal.

The heat expansion sheet 20 is made of a graphite material having a plate-like structure and expanding by heat.

The mounting means 30 includes a receiving portion 31 formed to be open at a front surface of the frame 10 and two receiving portions 31 formed at the left and right ends of the receiving portion 31 And a recess 32. The left and right end portions of the heat expansion sheet 20 are inserted into and fixed to the two recesses 32 in a state where the heat expansion sheet 20 is disposed in the accommodating portion 31. As a result, the heat expansion sheet 20 can be slidably inserted into the accommodating portion 31 and the two recesses 32 from top to bottom or from bottom to top.

On the other hand, in the door fire units of the first and second embodiments,

A sealing member 50 having a fitting portion 40 and a corresponding fitting portion 51 inserted into the fitting portion 40 and an elastic head 52 projecting from the fitting fitting portion 51 to come into contact with the door frame 2 .

1 and 2, in the fireproof unit for the door of the first embodiment, the fitting portion 40

And a T-shaped inner space extending in the left direction at the left end of the frame 10 as viewed from above.

Therefore, it is preferable that the corresponding fitting portion 51 also has a T-shaped cross-section so that it can be slidably inserted into the fitting portion 40.

The elastic head 52 of the sealing member 50 comes into contact with the edge of the door frame 2 in a state where the frame 10 is attached to the end of the door 1 due to magnetism, The air flow inside and outside the door 1 is blocked.
