Metal fireproof door airtight device

The present invention relates to a metal fireproof roll door airtight device, in particular to a metal fireproof roll door airtight device capable of preventing derailment, thereby improving the airtight effect of the metal fireproof rolling door and achieving the blockage of hot gas smoke. Turbulent.

According to the general fire door installation, the main purpose is to prevent the rapid spread of fire in buildings. Therefore, in the "Technical Rules for Buildings", it is mandatory to provide firewalls, fire slabs and fire doors and windows to separate compartments. The structure of the door can be roughly divided into two types, one is a roll-type fire-proof roll door, such as the M415975 patent case; the other is a metal fire-proof roll door composed of a plurality of roll-up door hinges, such as M469367, M480587 The patent case is.

Since the roll-up type fire-proof roll door itself is a roll screen composed of fireproof cloth, it can not be used as a control for opening and closing the door. It can only be put down when the fire occurs, so as to block the spread of the fire; The fireproof cloth used in the fireproof roll door is a softer material. Therefore, when lifting and lowering operations, it must be guided by the limit of the two sides of the track, and through a track clamp with a press function in the track to provide the After the roll-up type fireproof roll door is lowered to reach the fixed position, the roll-type fireproof roll door is fixed by interlocking the clamped seat of the track clamp to prevent the fireproof roll door from loosening. Take off the situation and form a gas-tight effect to block the turbulence of the insulating gas (the relevant technical content can be referred to the M415975 patent); the roll-up prevention as described above Fire shutters do not have the function of anti-theft and control access control, so they cannot be universally installed in all areas of the building.

Therefore, in places where there is control of access control in buildings, metal fireproof rolling doors must be used. However, metal fireproof rolling doors provide thicker tracks on the sides of the metal fireproof rolling door. The width of the guiding opening is relatively widened, and the inside of the rail used for the metal fireproof rolling door does not have any airtight and pressing mechanism, so that there is a gap between the metal fireproof rolling door and the track. In addition to the big problem, when the metal fireproof rolling door is at a high temperature, it is easy to be deformed and derailed, resulting in the metal fireproof rolling door not completely effective in stopping the turbulence of the heat source and the smoke, and reducing the original It has the function of blocking the spread of smoke from fire.

In view of this, after many times of research and improvement, the creator of this case finally completed the metal fireproof door airtight device of this creation, that is, the purpose of the creation of the case is to provide a metal fireproof door airtight device capable of preventing derailment. In order to improve the airtight effect of the metal fire shutter door, and to achieve the blockage of the hot gas smoke.
