Description

Technical Field

[0001] This utility model relates to the field of fireproof board technology, specifically to a fireproof composite board that is resistant to bending. Background Technology

[0002] Fire-resistant composite panels are a type of building decoration material with excellent fire resistance. They are mainly composed of an inorganic fire-resistant substrate, a high-strength reinforcing layer, and a surface fire-resistant layer. They are characterized by high temperature resistance and flame retardancy, which can effectively prevent the spread of fire and improve building safety. At the same time, fire-resistant composite panels have high strength and are suitable for various scenarios such as walls, ceilings, and partitions. They are widely used in commercial buildings, subways, airports, and other public places.

[0003] However, traditional fire-resistant composite panels have certain limitations in terms of structural support. In particular, they are prone to bending and deformation when subjected to large external forces, which can lead to the separation and detachment of multi-layer structures. Furthermore, due to the lack of reasonable internal reinforcement structures or reinforcement layers, stress is concentrated in specific areas after being subjected to force, resulting in local damage or even material cracking, which affects the overall service life.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figures 1-2 The present invention provides a fireproof composite panel that is resistant to bending, comprising: an aluminum plate layer 1.

[0019] In this embodiment, as Figures 1-3 As shown, a reinforcing layer 2 is fixedly connected to the top of the aluminum plate layer 1, a first fire-resistant layer 3 is fixedly connected to the bottom of the aluminum plate layer 1, a second fire-resistant layer 4 is fixedly connected to the top of the reinforcing layer 2, and several straight grooves 7 are arranged equidistantly on the aluminum plate layer 1 and the reinforcing layer 2. A reinforcing rib 8 is fixedly connected inside the straight groove 7. The thickness of the middle part of the reinforcing rib 8 is greater than the thickness at both ends. An injection groove 9 is provided on the inner wall of the straight groove 7. The thickness of the aluminum plate layer 1 is greater than the thickness of the reinforcing layer 2.

[0020] Among them, the aluminum plate layer 1 provides basic support, the top reinforcing layer 2 enhances the overall strength, the second fire-resistant layer 4 improves the fire resistance, the bottom first fire-resistant layer 3 forms double fire protection, the reinforcing rib 8 is thicker in the middle and thinner at both ends, making it more flexible under stress and enhancing its bending resistance. In addition, the inner wall of the straight groove 7 is provided with an adhesive injection groove 9 for filling adhesive and improving the interlayer bonding force.

[0021] like Figure 2 As shown, the aluminum plate layer 1 and the reinforcing layer 2 have several oblique grooves 6 arranged at equal intervals on their opposing surfaces. The first fire-resistant layer 3 and the second fire-resistant layer 4 have several oblique protrusions 5 arranged at equal intervals on their adjacent surfaces. The oblique protrusions 5 are fitted into the oblique grooves 6.

[0022] Furthermore, the oblique groove 6 located on the aluminum plate layer 1 is opened in the opposite direction to the oblique groove 6 located on the reinforcing layer 2.

[0023] Among them, the oblique grooves 6 on the opposite sides of the aluminum plate layer 1 and the reinforcing layer 2 are opened in opposite directions to form an interlaced structure, and the oblique ribs 5 are embedded in the oblique grooves 6 to improve the bending resistance and make the composite plate more stable and reliable when under stress.

Stainless steel plate has high hardness and bending resistance, which can enhance the bending strength of the composite plate. The first fire-resistant layer 3 and the second fire-resistant layer 4 are both rock wool boards. Rock wool boards have a high melting point and can maintain a stable structure even in high-temperature environments.
