A column, beam and wall combination is a column or a beam or a wall of a building. The combination comprises a left side panel, a right side panel, a fixing plate, connection wood, an inner baffle, vesuvianite concrete, a reinforced net and cement concrete. The left side panel and the right side panel are artificial plates, the surfaces of the side panels are smooth, the fixing plate, the connection wood, the inner baffle and the vesuvianite concrete are arranged between the left side panel and the right side panel, and the vesuvianite concrete is porous, low in weight and poor in vibration and heat conduction performance. The beam comprises beam vesuvianite concrete and a beam reinforced net, and a steel bar sleeve is arranged at the upper end of a column reinforced net. The combination has the advantages that shock resistance, heat isolation and sound isolation are achieved, the living comfort degree is good, the combination can be produced in batches on assembly lines in enterprises, construction and production are convenient and safe, installation and construction are convenient, no scaffolds need to be erected, and a lot of time can be saved, and can be widely used in the building field.
