Description

Fireproof hem hem structure capable of improving airtightness

The present invention relates to a fireproof hem hem structure which can improve the airtight effect, and particularly relates to a structure which can make the bottom of the hem of the fireproof rolling screen evenly affix to the ground, thereby effectively achieving the airtight effect to prevent the airflow. Circulation, thereby preventing the spread of fire.

According to the high urban population density, in order to solve the needs of living and office, urban buildings can only develop towards high floors, but high floors have unresolved bottlenecks in public safety, especially in the event of fire. The range that fire truck ladders can reach also has its limits. For this reason, in modern building planning, the safety of fire prevention must be taken into account; especially for large-area public buildings, fire-proof curtains are mostly used as fire-proof partitions. The main reason is that fire-proof curtains are easy to control, and It will affect the vision of the space and facilitate the access of people, goods and vehicles. When a fire occurs, it can be combined with the detection of the automatic sensing system to timely release the fire curtain to prevent the spread of the fire source, effectively ensuring the safe evacuation of personnel and reducing the fire damage.

However, the structural arrangement of the general fire curtain (also referred to as the curtain) (as shown in the first figure) is provided in the chamber 11 of the roll box 1 with a reel 12, the surface of which is coupled to wind a fire roll. Curtain 13, the normal reel 12 winds the fire hammer screen 13, and the fire curtain 13 is lowered from the opening 10 of the chamber 11 when a fire occurs, thereby blocking the spread of the fire; however, a problem often occurs in actual use. That is, because the length of the fire curtain 13 is as long as ten When the hem 131 of the fireproof curtain 13 contacts the ground E, the hem 131 is not closely attached to the ground E, and the airflow easily rushes through the gap, directly affecting The fire curtain 13 blocks the effect of the spread of fire and is criticized by people.

In view of this, the creators of this case have finally completed the creation of this case after numerous research and improvement, that is, the purpose of this case is to provide a fire-proof hem hem structure that can improve the airtight effect, thereby effectively achieving the airtight effect. Prevent the circulation of airflow and prevent the spread of fire.

In order to achieve the above-mentioned purpose of the present invention, the fireproof hem hem structure of the present invention capable of improving the airtight effect is provided with a chamber in a roll box, the contents of the chamber being provided with at least one reel, and the reel is wound a fireproof roll screen, the bottom side of the roll box is provided with a roll-through opening for the fireproof roll screen to pass through and to open or wind up the inlet and outlet ports, characterized in that: the hem of the fireproof roll screen is provided with a sleeve The sleeve has a content space, and the content space is provided with at least one weight member and a soft member, the soft member is located under the weight member, and the bottom surface of the soft member is flatly attached to the bottom of the sleeve, and is subjected to the The weight of the weight member is pressed, so that the bottom of the hem can be evenly leveled on the ground, thereby effectively achieving the airtight effect to prevent the circulation of the airflow, thereby preventing the fire spreader.

The above weighting member further comprises a weight rod and a weight.

The weight member further includes a weight rod and a weight, and the weight rod is located above the weight.

The weighting member further includes a weight bar and a weighting block, and the weight bar is located above the weighting block, and the bottom surface area of the weighting block is approximately equal to the surface area of the soft component.

In the above hem, the bottom of the swing sleeve has at least one side extending outwardly with one side wing.

Please refer to the second, third, and fourth figures. The present invention is provided with a chamber 21 in a roll box 2, and the chamber 21 is provided with at least one reel 3, and the reel 3 is wound around a fireproof curtain 4. The bottom side of the roll box 2 is provided with a roll screen opening 22 for the fireproof roll screen 4 to pass through and to open or wind up the inlet and outlet ports, characterized in that the hem 41 of the fireproof roll screen 4 is provided with a The pendulum sleeve 40 has a content space 410. The content space 410 is provided with at least one weight member B and a soft member 413. The soft member 413 is located under the weight member B. The bottom surface of the soft member 413 It is flatly attached to the bottom of the pendulum sleeve 40 and pressed by the gravity of the weight member B, so that the bottom surface of the hem 41 can be evenly leveled on the ground E, thereby effectively achieving the airtight effect, thereby preventing the circulation of the airflow and thereby preventing the fire. Spreader.

As shown in the second figure, it is indicated that the fireproof curtain 4 is naturally lowered, that is, when the fire occurs, the fireproof curtain 4 is naturally lowered; as shown in the third figure, the hem of the fireproof curtain 4 is 41. Touching the ground E, since the soft member 413 can be completely flat against the bottom of the swing sleeve 40 and pressed by the gravity of the weight member B, the bottom portion of the hem 41 can be more evenly leveled on the ground E, thereby effectively Achieve airtightness to prevent the flow of airflow and thus prevent the spread of fire.

The weight member B further includes a weight bar 411 and a weight 412. The weight bar 411 is located above the weight 412. The bottom surface of the weight 412 is approximately the same as the surface area of the soft member 413. Therefore, the weight 412 can be more uniformly pressed by gravity to press the soft member 413, so that the bottom of the hem 41 can be more evenly leveled on the ground E, thereby effectively achieving the airtight effect to prevent the airflow from flowing, thereby preventing the airflow. The fire spreader.

The lower hem 41 has a side wing portion 414 extending at least on one side of the bottom portion of the swing sleeve 40. When the side wing portion 414 abuts against the ground E, the airtight effect of the hem 41 on the ground E can be further enhanced.

In summary, the fire hem hem structure of the present invention can make the bottom of the hem of the fireproof curtain evenly affix to the structure of the ground, thereby effectively achieving the airtight effect, thereby preventing the circulation of the airflow and preventing the fire from spreading. Effectively solve the lack of the existence of the formula; and the technical means used in this creation is unprecedented, so this creation is unique to the novelty and progressive requirements of the new patent.
