The wave polymerized hollow plates are placed between adjacent horizontal brick layers to maintain openings under the layers, including: the first relatively thin plane member, and the second relatively thin plane member. Each of the first and second relatively thin planar members has a density between approximately 0.7gm/cc and 1.3gm/cc. Among them, the first relatively thin plane member and the second relatively thin plane member are connected to each other through the ribs of the first relatively thin plane member and are connected to the second relatively thin plane member.
Hollow plate turnover box is a rectangular box made up of front and rear, right and left side plates and bottom plates. The front, rear, right and left side plates and lower bottom plates are fixed and connected. A mediastinum plate and a plurality of transverse partitions are arranged in the box body.
