Description
Technical Field

[0002] Reinforced concrete panels are processed in prefabrication plants or construction sites for building assembly, referred to as wall panels or sidings. Using prefabricated concrete wall panels to build assembled large-panel buildings can improve the degree of factory-based and mechanized construction, reduce on-site wet operations, save on-site labor, overcome seasonal influences, and shorten the construction period.
[0003] During the transportation of prefabricated wall panels, the edges and corners of the prefabricated wall panels are relatively fragile parts. If the edges and corners of the prefabricated wall panels are not protected, when the prefabricated wall panels collide with the outside world, the edges and corners of the prefabricated wall panels are easily damaged, thereby affecting subsequent use. Most existing devices use foam to protect the edges and corners of the prefabricated wall panels, but the foam itself is also relatively fragile and has a poor protective effect on the edges and corners of the prefabricated wall panels.
