Prefabricated foaming ceramic bearing platform moulding bed and mounting method

The invention discloses a prefabricated foamed ceramic bearing platform moulding bed and a mounting method, and relates to the technical field of moulding bed bearing platforms. Comprising four foaming ceramic plates, namely two first foaming ceramic plates and two second foaming ceramic plates, and the first foaming ceramic plates and the second foaming ceramic plates are consistent in structure; the foamed ceramic plate is composed of an upper part and a lower part, the upper part of the foamed ceramic plate is shorter than the lower part of the foamed ceramic plate, the distances between two side surfaces of the upper part and two corresponding side surfaces of the lower part are the same, and the widths of the upper part and the lower part are consistent; the upper portions of the two first foaming ceramic plates face upwards and are arranged in parallel, the lower portions of the two second foaming ceramic plates face upwards and are perpendicular to the two first foaming ceramic plates, and the lower po
