[0022] Embodiment 1

[0023] As Figures 1-5 described, a curtain wall aluminum plate provided by the present utility model includes an aluminum frame 1 and a plate body provided on the aluminum frame 1. The aluminum frame 1 of the present application adopts a hollow structure. The aluminum frame 1 is provided with a placement groove corresponding to the plate body, so that the plate body of the present application is embedded on the aluminum frame 1. The plate body includes an inner plate body 2 and an outer plate body 3. The inner plate body 2 and the outer plate body 3 are installed on the aluminum frame 1 by welding or using screws. A plurality of heat insulation layers 4 are provided between the aluminum frame 1 and the outer plate body 3. There are 3 heat insulation layers 4 between the aluminum frame 1 and the outer plate body 3 of the present application. The heat insulation layer 4 is composed of a mineral wool board layer, a polystyrene board layer and a glass wool board layer in sequence from outside to inside. Through the setting of the heat insulation layer 4, the heat exchange between the indoor and outdoor can be reduced, and the influence of the external high temperature or low temperature weather on the indoor can be reduced, improving its heat insulation effect.

[0024] A noise reduction layer is provided between the aluminum frame 1 and the inner plate body 2. The noise reduction layer is a wavy sound insulation damping plate 5. Sound absorption strip groups 6 are arranged at equal intervals in the sound insulation damping plate 5, and sound absorption cotton is filled between two adjacent sound absorption strip groups 6. A plurality of sound absorption holes 7 are formed in the sound insulation damping plate 5 corresponding to the sound absorption strip groups 6. Through the setting of the sound insulation damping plate 5, the present application can effectively achieve the effect of noise reduction and sound insulation. A connecting buckle strip (not shown in the figure) for facilitating the connection and installation of aluminum plates to each other may be provided at the side end of the aluminum frame 1. When the inner plate body 2 and the outer plate body 3 are fixedly connected to the aluminum frame 1, a heat insulation cavity 14 is formed between the heat insulation layer 4 and the noise reduction layer, further reducing the heat transfer and improving the heat insulation effect of the curtain wall aluminum plate of the present application.

[0025] As Figure 3 described, a fall prevention buckle 8 is connected to the inner plate body 2 of the present application through a connecting rod 9. Through the setting of the fall prevention buckle 8, the present application can improve the compressive resistance effect of the curtain wall aluminum plate and improve its safety performance during use, enabling it to cope with bad weather and preventing the aluminum plate from falling during cleaning and maintenance. The fall prevention buckle 8 includes a cylinder body 81 and an axial notch 82 provided on the cylinder body 81. The axial notch 82 is connected with symmetric arc-shaped elastic pieces 83. The arc-shaped elastic pieces 83 are composed of a connecting part 10 and an arc part 11. The distance between the arc parts 11 between the arc-shaped elastic pieces 83 is less than the length of the axial notch 82. During the installation process, the curtain wall aluminum plate of the present application is pressed onto the installation rack. The installation rack is provided with an installation rod corresponding to the fall prevention buckle 8 of the present application, that is, the fall prevention buckle 8 of the present application is connected to the installation rod provided on the installation rack by pressing the curtain wall aluminum plate.

[0026] Embodiment 2

[0027] On the basis of the above embodiment, in order to improve the force balance after the connection of the curtain wall aluminum plate and improve its connection stability in this embodiment, as Figures 1-3 described, two fall prevention buckles 8 are provided in the present application, and the fall prevention buckles 8 are arranged on the inner plate body 2 at equal intervals and staggered through the connecting rod 9, improving the compressive resistance effect of the curtain wall aluminum plate of the present application, enabling it to adapt to use in multiple environments and improving its practical performance. The connecting rod 9 of the present application adopts a buffer spring rod. Through the setting of the buffer spring rod, part of the contact force during the installation process can be absorbed, slowing down the hard contact between the fall prevention buckle 8 and the installation rod and improving the service life of the fall prevention buckle 8. A buffer layer 12 is provided on the inner wall of the cylinder body 81, and the cylinder body 81 is fixedly connected to the inner plate body 2 through the connecting rod 9, absorbing the contact noise between the installation rod and the fall prevention buckle 8 under bad weather and playing a protective role in the contact surface between the fall prevention buckle 8 and the installation rod. Through the setting of the fall prevention buckle 8, the present application can also improve the subsequent installation efficiency. The existing installation of aluminum plates is to install one piece and then feed and install the next piece. In the present application, during the installation process, the aluminum plate is first placed on the installation rod, and then the aluminum plate is fixed to the installation rack through the aluminum plate installation process, achieving a significant improvement compared to the existing aluminum plate installation efficiency.

[0028] Embodiment III
