Fireproof roll box airtight structure improvement

The present invention provides an airtight structure improvement of a fireproof rolling box, in particular, the two sides of the opening on the lower side of the roll box are bent in the accommodating space of the roll box, and two plates are located on the opposite side of the fire shutter 2, and the two plates are The inner side surface is respectively provided with an airtight strip. During the process of closing the fire shutter, the two airtight strips are abutted against the two side surfaces of the fire shutter, so that the inside of the coil box is airtight.

According to the current high-rise buildings in the metropolitan area of the society, no matter whether it is at home or office, public places, etc., a large number of decorative materials will be used for the design of the indoor environment, and the indoor environment will be beautifully decorated, but a large number of decorative materials. It has extremely high flammability. In the event of fire, the decoration materials are prone to strong smoke, block the escape route, and delay the escape and rescue time. In the fire statistics, the casualties caused in the fire scene are found. Most of them are caused by inhaling too much smoke, and the proportion of those who are directly burned by fire is lower.

Therefore, in the current architectural design and planning, it is necessary to consider the safety at the time of fire to prevent the hot air flow and smoke from burning, so most of the interior of the building will be equipped with a smoke control system to cause the fire to occur. The hot air flow and the thick smoke generated by the time are separated, and the existing smoke control system mainly uses equipment such as a smoke-proof fire shutter, and the structure of the general smoke-proof fire shutter is equipped with a roll box on the ceiling. And a reel is arranged in the accommodating space formed inside the roll box, and a fire shutter is wound on the reel, and when the fire occurs, the automatic sensing can be matched The system timely releases the fire shutter from the opening at the bottom of the accommodating space to the ground to block the spread of the fire, thereby effectively ensuring personnel safety and evacuation routes, thereby reducing damage and damage caused by fire.

However, in actual use, after the fire curtain is lowered to the ground, there is a gap between the opening of the roll-box accommodation space and the two side surfaces of the fire shutter, so that the inside of the package cannot be airtight. The smoke and hot air generated by the fire can be plunged from the side of the fire shutter to the inside of the storage space of the roll box through the gap, and then rushed to the other side of the fire shutter, so that the fire area has not been fired. Under the effect of concentrated gathering of smoke and hot air, people are exposed to the flash fire crisis at any time, threatening people's property and life safety.

Therefore, how to solve the above-mentioned lack of inconvenience and inconvenience is the direction that the relevant industry players in this industry are eager to study and improve.

Therefore, in view of the above problems and deficiencies, the creators have collected relevant information, and through multi-party assessments and considerations, and through years of experience in the industry, through continuous trials and revisions, we have designed a fire-resistant coil box airtight structure improvement. .

The main purpose of the creation is that the inside of the roll box is formed with a receiving space, and a reel is arranged in the accommodating space, and a fire shutter is wound on the reel, and the two sides of the fire shutter are embedded in the bottom of the roll box. The two door rails on the two sides are further provided with a weight base located between the two door rails and supporting the door rail lifting displacement for blocking the outside of the opening below the accommodating space at the bottom of the fire shutter, wherein the magazine is located at the two sides of the opening In order to bend into the accommodating space, there are two plates located on opposite sides of the fire shutter, and the two plates are respectively provided with airtight strips on the opposite inner side surfaces, and the fire shutters are matched with the weight base to make them from the roll box. Pull out at the bottom opening and descend to the ground along the two-door rail In the process, the two airtight strips are continuously pressed against each other on the two side surfaces of the fire shutter, so that the inside of the coil box is continuously airtight, thereby preventing the hot air flow generated by the fire and the smoke from being fireproof. After one side enters the roll box, it is then smashed to the other side of the fire shutter to achieve the purpose of curbing the spread of fire.

The secondary purpose of the creation is that when one side surface of the fire shutter is pressed by the hot air flow to cause the curtain surface to expand or pull down, the second airtight strip composed of the elastic material can be used to generate the corresponding elasticity. The deformation is closely attached to the two side surfaces of the fire shutter, thereby maintaining the airtight state, thereby achieving the purpose of improving the reliability of the fireproof capability.

Another purpose of the creation is that the two airtight strips can maintain the airtight state inside the roll box, so that the weight base does not need to be additionally designed with an airtight structure, and the second airtight strip can be used together to maintain the inside of the roll box. The airtight state prevents the fire from spreading, thereby reducing the design and manufacturing cost of the counterweight base.
