Problems solved by technology

[0002] In buildings with large openings such as high-rise buildings, business halls and exhibition halls, fire-resistant shutter doors are widely used. In addition to the functions of ordinary doors, fire-resistant shutter doors also have the functions of fire prevention, smoke prevention, and suppression of fire spread. However, the existing fire-proof shutter door that is convenient for fire protection is extended and closed downward when a fire occurs. After the line is damaged or burned, the shutter door cannot be manipulated, and at the same time, it hinders fire extinguishing from the outside to the inside, which is not conducive to firefighters or firefighters. Rescuers carry out timely extinguishing and control of the fire, and the general rolling shutter door is easily deformed under high temperature, which increases the danger of fire rescue

preparation example Construction

[0040] The preparation method of high silica glass fiber comprises the following steps:

[0041] (1) Weigh silicon dioxide, silicon carbide, alumina, boron trioxide, and sodium oxide according to the specified parts by weight, grind and mix to form a primary mixture, and after the particle size of the primary mixture reaches nanoscale, according to the specified weight parts Weighing rare earth oxides, adding them to the primary mixture, and continuing to mix to form the final raw material mixture, the particle size of the final raw material mixture reaches nanoscale;

[0042] (2) The final raw material mixture is placed in a corundum crucible, and the corundum crucible is placed in a silicon molybdenum rod electric heating furnace. Put it into a muffle furnace, heat treatment in phase separation at 460°C for 14 hours, and obtain a glass frit;

[0043] (3) Put the glass frit into the wire drawing furnace, melt it twice at 9000°C and draw it.

[0044] The rotating speed of th...

Embodiment 1

[0062] Embodiment 1: In the initial state, the main body 1 of the rolling shutter door, the guide rail I28 and the guiding rail II29 are installed and fixed on the wall of the building opening. Rewinding and unwinding, when the motor 9 drives the roller shaft 7 to rotate clockwise or counterclockwise, the collar 13 drives each roller shaft 21 to rotate. Because the motor 9 drives the roller shaft 7 to rotate slowly, when each roller When the 21 is rotated to any side and tilted, the left and right sides of the three rollers 21 are subjected to different gravity, so that the sliding plate 18 slides and balances in the direction opposite to the rotation direction of the collar 13, which can be used as a common rolling shutter door.

Embodiment 2

[0063] Embodiment 2: When a fire breaks out in a shopping mall or exhibition hall, after the evacuation of the people in the field, the motor 9 is controlled to rotate clockwise to put down the main body 1 of the rolling shutter door, and the fire in the shopping mall or exhibition hall is blocked and suppressed. When the firefighters extinguish the fire, The support arm 25 drives the rotating plate 17 to rapidly rotate clockwise through the impact of the water gun on the baffle plate 26, and the rotating plate 17 squeezes the rollers 21 of the sliding plate 18 in a balanced state, so that the rollers 21 are engaged with the locking grooves 27. Inside, the extrusion drives the sleeve ring 13 to rotate, the sleeve ring 13 drives the sleeve 11 to move clockwise, the clamping shaft 23 falls from the arc groove 12 to the lower side, and the guide piece 32 guides the dropped clamping shaft 23. The clamping shaft 23 is slid downward along the lifting chute II31, so that the upper end...

Abstract

The invention discloses a fireproof rolling shutter door which is convenient for fire fighting. A composite steel fire shutter II is arranged on the side, and the lower end of the composite steel fire shutter II is hinged with the composite steel fire shutter I. The device uses three rollers in the sliding plate to balance the gravity to ensure the rolling and unwinding of the main body of the rolling shutter door under normal circumstances. The disc rotates to make the card shaft fall down. After the upper end of the composite steel fire shutter II is folded downward to form an opening, firefighters can put out the fire in time through the opening. The high silica glass fiber layer has good resistance to fire. High temperature resistance to prevent high temperature deformation of equipment.
