The frame structure does not need to spray mud and cement. Frame structure is a structural system composed of columns, beams, walls and other components, which mainly undertakes the load transfer and support functions of buildings. The frame structure is made of reinforced concrete, steel structure or wood structure, which has sufficient strength and stability and does not need shotcrete reinforcement. Sprayed concrete is used for soil reinforcement and protection in civil engineering. It is a kind of soil mixed with clay and water, which has good cohesiveness and impermeability and can be used to reinforce soil and fill holes.
