The surface layer of the plate is made by mixing ordinary silicate cement and granulated blast furnace slag in a certain proportion, and then adding a certain proportion of foaming agent and modifier to fully wrap the core layer of the plate. The core layer of the plate is made of ordinary silicate cement, granulated blast furnace slag and polystyrene particles after modification. An interface agent is arranged between the surface layer and the core layer of the plate to improve the adhesion between the two. The inner surface of the surface layer of the plate is provided with a mesh cloth. A raised male tenon is arranged at one end of the wall panel, and a female groove is arranged at the other end of the wall panel. The sizes of the male tenon and the female groove match. CN201720176850.6 discloses that a raised male tenon is opened on one side of the wall panel, and a female groove is opened on the other side of the wall panel. Once the wall panel of the above structure becomes loose during transportation, it will not only cause danger, but also the wall panel will fall and cause the male tenon or the female groove to collide or be damaged, which will make it impossible for adjacent wall panels to dock.
