However, the existing honeycomb core sandwich composite board has simple structure and only has a surface layer and a honeycomb core layer, for example, CN201020165199.0 in China published patent discloses a pyramid honeycomb core composite board which comprises a pyramid honeycomb core and panels clamped on two sides of the pyramid honeycomb core, wherein the pyramid honeycomb core can be prepared by using metal plates/foils or nonmetal plates/sheets. The upper end surface of the pyramid honeycomb core is fixedly connected with the lower plane of the upper panel, and the lower end surface is fixedly connected with the upper plane of the lower panel. The panel 2 may be made of a metal material of 1mm to mm2, such as: industrial aluminum plates, stainless steel plates, and the like; non-metallic materials such as plastic plates, glass reinforced plastic plates, etc. of 1mm to mm2 can also be used. The panels on the two sides can be made of the same material or different materials in any combination, and are selected according to the use requirements and the environment.

However, the honeycomb core sandwich composite board in the prior art has the problem that the effective fire prevention cannot be realized due to the surface layer and the honeycomb core layer. In addition, because the honeycomb holes are formed in the honeycomb core layer, if the composite board needs to be nailed and installed during use, the problem that the nail holding force is poor and is not beneficial to installation is caused by the existence of the honeycomb holes.
