Fireproof box airtight structure

The present invention relates to a fireproof coil box airtight structure, which uses an airtight strip to seal the gap between the fireproof curtain and the coil box, thereby preventing the flow of the hot air flow and effectively preventing the spread of the 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 (as shown in the first figure) is provided in the chamber 11 of a roll box 1 with a reel 12, the surface of which is coupled to wind a fire curtain 13, usually 12 is wound around the fireproof curtain 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, in actual use, after the fire curtain 13 is lowered, There is a large gap between the opening 10 of the chamber 11 and the two sides of the fireproof curtain 13, so that a hot air flow can flow from one side of the fire curtain 13 into the chamber 11 Inside, it is turbulently flowed to the other side of the fire curtain 13, and as a result, of course, the flow of the hot air flow cannot be completely blocked, and the safe area where the fire has not occurred is exposed at any time due to the effect of the concentrated flow of the hot air flow. The hot air stream flashes in the crisis.

In view of this, after many times of research and improvement, the creator of this case finally completed the air-tight structure of the fire-proof coil box of this creation, that is, the purpose of the creation is to provide a gas-tight structure of a fire-proof coil box which can prevent hot air from flowing through the coil box. In order to prevent the fire from spreading to the other side of the fire curtain, the effective use of the fire curtain is effectively utilized.

In order to achieve the above-mentioned purpose of the present invention, the air-tight structure of the fire-proof roll box of the present invention is provided with a chamber in a roll box, the contents of the chamber being provided with a reel, the reel is wound with a fire-rolling curtain, the roll box The bottom side is provided with a box mouth seat, the box mouth seat is provided with a content space for accommodating one of the hem seats connected to the lower end of the fireproof roll screen, and a roll screen opening is provided at the top of the box mouth seat for the fire prevention The scroll passes through and is placed in or out of the opening and exiting port, wherein the top surface of the box mouth is located on both sides of the curtain opening, each of which is attached with a sealing strip, and one of the sealing strips is attached The first end side is fixed to the top portion, and a second end side of the sealing strip is a free end attached to a side of the fireproof roll screen and the roll screen opening, thereby sealing the fireproof roll The gap between the curtain and the curtain.

Another embodiment of the present invention relates to a fireproof box airtight structure, which is provided with a chamber in a roll box, the chamber is provided with a reel, and the reel is wound with a fireproof curtain, the bottom side of the roll box a box mouth seat is provided, the box mouth seat is provided with a content space for accommodating a hem seat connected to the lower end of the fireproof roll screen, and at the top of the box mouth seat is provided a roll-through opening for the fire-resistant roll screen to pass through and to put down or take-up into and out of the port, characterized in that: the fire-proof roll screen has a hem seat placed down to the ground for positioning, corresponding to the fire-proof roll screen A portion of the upper edge of the rolling screen is attached with an airtight strip on each of the two sides, a first end side of the airtight strip is fixed on the fireproof curtain, and a second end side of the airtight strip A free end is attached outwardly along the top surface of the box mouth to seal the gap between the fire curtain and the screen opening.

Referring to the second and third figures, the air-tight structure of the fireproof box of the present invention is provided with a chamber 21 in a roll box 2, and the chamber 21 is provided with a reel 3, and the reel 3 is wound a fireproof roll screen 4, the bottom side of the roll box 2 is provided with a box mouth seat 5, the box mouth seat 5 is provided with a content space 51 for accommodating a hem seat 6 connected to the lower end of the fireproof roll screen 4, and at the box mouth seat The top portion 52 of the 5 is provided with a roll screen opening 53 for the fireproof roll screen 4 to pass through and to open or wind up the inlet and outlet ports, wherein the top surface 52 of the box mouth base 5 is located near the roll screen. An airtight strip 7 is attached to each side of the opening 53 and a first end side 71 of the airtight strip 7 is fixed to the top 52, and a second end side 72 of the airtight strip 7 is provided. A free end attached to a side of the fire curtain 4 and the curtain opening 53 to seal the gap therebetween.

As shown in the second figure, the structure of the fireproof roll screen 4 is wound up by the creation of the usual roll box 2, and the hem seat 6 is received in the content space 51 of the box mouth seat 5, and the The second end side 72 of the second airtight strip 7 is freely attached to the two sides of the fireproof curtain 4 to seal the gap between the fireproof curtain 4 and the curtain opening 53; when a fire occurs, the The fire curtain 4 is lowered, and the force dragged by the fire curtain 4 will seal the second end side 72 of the airtight strip 7 downwardly between the fire curtain 4 and the curtain opening 53 ( As shown in the third figure, the hot air flow that blocks the fire zone enters the roll box 2 so that it can no longer flow to the other side of the fire curtain 4, effectively preventing the spread of the fire.

The fourth figure is another embodiment of the present invention, which is provided with a chamber 21 in a roll box 2, and the chamber 21 is provided with a reel 3, and the reel 3 is wound around a fireproof screen. 4, the bottom side of the roll box 2 is provided with a box mouth seat 5, the box mouth seat 5 is provided with a content space 51 for accommodating one of the lower hem seats 6 connected to the lower end of the fireproof roll screen 4, and at the top of the box mouth seat 5 52 is provided with a roll screen opening 53 for the fireproof roll screen 4 to pass through and to open or wind up the inlet and outlet ports, characterized in that the fireproof roll screen 4 has its hem seat 6 lowered to reach the ground E position. Corresponding to the upper edge of the curtain opening 53 of the fireproof curtain 4, an airtight strip 7' is attached to each of the two sides, and a first end side 71' of the airtight strip 7' is fixed to The first end side 72' of the airtight strip 7' is a free end which is attached outwardly along the surface of the top 52 of the box seat 5 to seal the fireproof curtain 4 A gap with the curtain opening 53.
