Through the driving component, roller one and roller two are driven to rotate relative to each other through the meshing gears, so that the fire curtain surfaces fixed on roller one and roller two are raised and lowered at the same time, thereby isolating the fire area in the building facility.

[0016] Optionally, the driving assembly includes a driving member, which is located in the rolling shutter box, and the driving member is arranged at one end of the fixed plate close to the fixed groove one on the rolling shutter box, a driving rod of the driving member is provided with a pulley one at one end away from the driving member, the roller two is located at one end of the gear and is provided with a pulley two, and a driving belt is provided between the pulley one and the pulley two.

[0017] By adopting the above technical solution, a driving member drives pulley one to rotate pulley two through a driving belt, so that pulley two drives the gear connected to pulley two to rotate, and roller one and roller two are rotated relative to each other through the meshing gears, so that the fire curtain surface is lowered and retracted, and different lowering speeds of the fire curtain surface are avoided as much as possible, which leads to untimely blocking of the fire area.

[0018] Optionally, the guide assembly includes a guide rail, which is arranged in the walls on both sides of the building wall, and a guide groove is opened on the guide rail, and the guide groove of the guide rail is in contact with both sides of the fire curtain surface.

[0019] By adopting the above technical solution, the guide rail is set on the side wall of the building wall, so that the guide rail contacts the two sides of the fire curtain surface, and a guide groove is opened on the guide rail along the direction of the building wall, so that the two sides of the fire curtain surface are against the inner wall of the fixed groove. The fire curtain surface falls along the direction of the guide groove in the guide rail and contacts the ground in the building facility, thereby isolating the fixed area in the building facility. Optionally, a support plate is provided on the inner wall of the rolling shutter box body above the driving member, and a fireproof filling member is provided on the support plate on the inner wall of the rolling shutter box body.

The position where the fireproof roller shutter is connected to the wall is sealed and isolated to prevent damage to the driving components of the fireproof roller shutter in the event of a fire, so that the fireproof roller shutter cannot be lowered in time, thereby isolating the fire area.

[0021] Optionally, a construction method for a fireproof roller shutter structure without the need for construction of door heads and lintels comprises the following steps: The rolling shutter box is arranged on the building wall so that the two ends of the rolling shutter box are located in the building wall, guide rails are arranged on the wall below the rolling shutter box, and the guide rails are embedded in the building walls at the two ends of the rolling shutter box; The rolling shutter assembly and the rolling shutter driving assembly are arranged in the rolling shutter box, and the rolling shutter driving assembly drives the rolling shutter assembly to rise and fall along the guide assembly to partition the passage in the building facility; When the fireproof rolling shutter needs to be inspected and repaired, the baffle on the rolling shutter box can be opened to observe the operating conditions of the rolling shutter assembly and drive assembly in the rolling shutter box. When maintenance is required, the rolling shutter box can be removed for repair and replacement.

[0022] Optionally, the operation of the drive assembly and the roller shutter assembly and the inspection of the fire shutter include the following steps: Roller 1 and roller 2 are rotatably arranged in fixed groove 1 at both ends of the rolling shutter box body, and pulley 1 is driven to rotate by a driving member fixed above the fixed plate. Pulley 1 drives pulley 2 arranged on roller 2 to rotate through a driving belt, so that roller 2 rotates, and roller 1 rotates synchronously with gears meshing with each other arranged on roller 2 to drive the fire curtain surface to move, so that the fire curtain surface moves up and down in the guide groove of the guide rail; The fire curtain surface fixedly connected to the rollers 1 and 2 moves up and down along the guide groove of the guide rail through the connecting groove of the roller box under the rotation of the rollers 1 and 2. Since the rollers 1 and 2 rotate relatively synchronously, the winding and releasing speeds of the fire curtain surface are consistent, thereby isolating the fire area of ​​the building facilities. The staff turns the handle on the baffle plate on the side wall of the rolling shutter box to offset the clamping part from the side wall of the rolling shutter box, so that the clamping part and the baffle plate are released from the side wall of the rolling shutter box, and the baffle plate is opened to facilitate observation of the condition of the reel and the fire curtain surface inside the rolling shutter box, as well as the operating condition of the drive assembly.

[0023] In summary, the present application includes at least one of the following beneficial technical effects: 1. Set the rolling shutter box under the top plate in the building wall, rotate the roller of the rolling shutter assembly in the fixed grooves at both ends of the rolling shutter box, and set a partition drive assembly and a fixing plate of the rolling shutter assembly in the rolling shutter box to fix and support the drive assembly.

After the handle is rotated, the clamping piece arranged on the handle rotating rod abuts against the inner wall of the rolling shutter box body, and the side wall of the rolling shutter box body is clamped by the baffle plate and the clamping piece, so that the baffle plate and the rolling shutter box body are fixed. After the handle is rotated, the clamping piece is also in contact with the support frame, and the clamping piece is limited to prevent the clamping piece from rotating too far and staggering with the side wall of the rolling shutter box body, so that the baffle plate cannot be fixed with the rolling shutter box body; 3. A support plate is arranged on the inner wall of the rolling shutter box above the driving part, and a fireproof filling part is filled between the rolling shutter box above the support plate to fill the gap in the rolling shutter box, and the position where the fireproof rolling shutter is connected to the wall is sealed and isolated to prevent damage to the driving components of the fireproof rolling shutter in case of fire, so that the fireproof rolling shutter cannot be lowered in time and the fire area is isolated.
