The present invention relates to a fire prevention shutter for a building, and in particular, when installing an emergency door composed of a plurality of door slats which are fastened up and down for escape on one side of a fire shutter that is installed to freely move along a guide rail in case of fire, It relates to a shield member for fire shutters to prevent the occurrence of a gap between the door slat forming an emergency door and the shutter slat forming a fire shutter while the warp is deformed by heat.

As is well known, the building mandates the installation of a fire shutter as required by the Fire Protection Law to prevent the fire from spreading to the surroundings and to protect the human life by quickly closing the ignition point in the event of a fire.

Although not illustrated, the fire shutter has an elongated plate-like slat connected up and down, a guide rail embedded in a side wall of the building so that the slat can be moved up and down, and installed on the ceiling of the building to lift the slat up and down. It consists of a shutter box with a built-in drive.

Such a fire shutter can prevent external persons from entering into a specific space blocked by the slats, and prevents external air from entering the ignition zone in the event of a fire. It must be able to fulfill various functions as well as preventing the emission of flames and toxic gases to the outside.

In addition, in the event of an emergency such as a fire, a particular space is to be sealed off, and an emergency exit for rapid escape of those who remain in the sealed space is required, and such an emergency exit is not limited to the function required above. There is a structural constraint to be installed.

Therefore, the most common form is to install an independent emergency door that is separately stored after cutting the lower one corner of the fire shutter.

However, this type of emergency door is equipped with emergency door at the point corresponding to the edge cutout of the slat before the slat is lowered when using the fire shutter so that the emergency door is fixed by the descending slat and wound the slat. When raising the emergency door to be separated from the slats to be stored separately, the installation and management of the emergency door is accompanied with a lot of difficulties, it was virtually impossible to install it quickly in an emergency situation such as a fire.

In view of these problems, the emergency door made of slats is integrally provided with the fire door shutter made of the slats so that the emergency door is provided when the slats descending the fire shutters are opened, which is opened and closed through the hinge member.

That is, the hinge member includes a spring having a considerable elasticity, and the emergency door made of the slat is automatically closed by the elasticity of the spring.

However, in the related art, a separate shielding plate is formed between the leading edge of the emergency door and the entrance-side tip of the slat to shield the emission of flame or toxic gas.

However, in the case of the shielding plate as described above, when the bending deformation occurs at the leading edge of the emergency door due to the heat caused by the fire, the overlapping state of the shielding plate installed at the point where the emergency door and the fire door shutter slats meet becomes poor. There was no choice but to create a gap, which led to the closure of the fire shutters that did not properly suppress the release of flames and toxic gases from the fire zone.

Therefore, the present invention has been devised to solve the conventional problems as described above, while the top edge of the door slat forming the emergency door and the exit side end of the shutter slat forming the fire shutter, respectively, overlapping each other firmly fixed state The first and second shielding members are installed and configured to maintain the overlapping state of the first and second shielding members even when bending deformation occurs at the leading edge of the door slats forming the emergency door due to the heat caused by the fire. Therefore, the object of the present invention is to provide a shield member for fire prevention shutters that can effectively prevent the discharge of flames and toxic gases to the outside.
