Wall panel, the name of furniture parts in ancient Ming and Qing Dynasties. The vertical panels located on the left and right sides of the furniture are collectively referred to as "side panels" or "wall panels". Now refers to a building material. It is a house structure with a load-bearing system composed of walls and floors. The load-bearing walls of the wall panel structure can be made of bricks, blocks, prefabricated or cast-in-place concrete. According to the different materials and construction methods, it can be divided into three categories: hybrid structure, prefabricated slab structure, and cast-in-place wallboard structure.
