Description

Technical Field

[0001] The utility model relates to the technical field of aluminum single plate manufacturing, in particular to a double-layer fireproof and heat-insulating aluminum single plate curtain wall. Background Art

[0002] Aluminum veneers usually use high-quality aluminum alloy plates as the base material, which has good rigidity and stability. Aluminum veneers are widely used in modern buildings due to their excellent physical properties and decorative effects. They not only increase the aesthetics of the building, but also provide reliable protection. However, in the event of a fire, the temperature of the aluminum veneer will be too high due to excessive temperature, which may cause the aluminum veneer to fall off.

[0003] A Chinese patent (authorization announcement number: CN215977957U) proposes a double-layer fireproof heat-insulating aluminum veneer curtain wall, including a first aluminum plate layer, a second aluminum plate layer and an inner frame, the first aluminum plate layer and the second aluminum plate layer are connected by the inner frame, the outer surfaces of the first aluminum plate layer and the second aluminum plate layer are both provided with a fireproof layer, the inner side of the inner frame is provided with a heat-insulating support assembly, and the heat-insulating support assembly includes a first heat-insulating layer, a second heat-insulating layer, a first reinforcing rib and a second reinforcing rib. The double-layer fireproof heat-insulating aluminum veneer curtain wall of the utility model can improve the fireproof and heat-insulating performance of the first aluminum plate layer and the second aluminum plate layer through the fireproof layer, the first heat-insulating layer and the second heat-insulating layer, so that the fireproof and heat-insulating performance of the aluminum veneer curtain wall is good, and the first sealing ring and the second sealing ring prevent rainwater from entering the aluminum veneer curtain wall, so that the waterproof performance of the aluminum veneer curtain wall can be improved, and the aluminum veneer curtain wall can be made light while improving the supporting performance of the aluminum veneer curtain wall.

[0004] In the above existing schemes, when a fire occurs, the temperature of the aluminum veneer may be too high, causing the aluminum veneer to fall off, posing a threat to pedestrians on the ground. In order to solve the problem of the aluminum veneer falling off due to the high temperature of the aluminum veneer, we propose a double-layer fireproof and heat-insulating aluminum veneer curtain wall.

Since ether is arranged inside the heated cylinder, according to the characteristics of ether, which expands when heated and contracts when cooled, the expansion of ether will drive the pneumatic piston to move. When the pneumatic piston moves downward, it will drive the fireproof pull rope to move. The fireproof pull rope will pull the second fireproof aluminum plate to rotate. The abutment block inside the second fireproof aluminum plate abuts against the folding rubber sleeve, and the folding rubber sleeve contracts.

When the fire rope is replaced, rotate the rotating circle clockwise again. The rotating circle will abut against the rotating block, and the rotating block will drive the bite teeth to abut against the fire rope. At this time, the replacement of the new fire rope is completed. BRIEF DESCRIPTION OF THE DRAWINGS
