The invention provides an assembling type novel adjustable dry hanging assembly. The assembling type novel adjustable dry hanging assembly comprises an upright column, a first hanging-buckling slidingrail, a second hanging-buckling sliding rail, a first hanging-buckling assembly and a second hanging-buckling assembly, wherein the first hanging-buckling assembly is hung and buckled on the first hanging-buckling sliding rail; the second hanging-buckling assembly is hung and buckled on the second hanging-buckling sliding rail; the first hanging-buckling assembly comprises a first screw base piece pre-embedded in a surface plate block as well as a first metal connecting piece fixed with the first screw base piece through a first bolt; the first metal connecting piece is hung and buckled withthe first hanging-buckling sliding rail in a matched way; the second hanging-buckling assembly comprises a second screw base piece pre-buried in the surface plate block as well as a second metal connecting piece fixed with the second screw base piece through a second screw; and the second metal connecting piece is hung and buckled with the second hanging-buckling sliding rail in a matched way. According to the assembling type novel adjustable dry hanging assembly, the mounting efficiency is greatly improved, special type work such as field electric welder is reduced, potential safety hazard caused by steel frame welding is reduced, a lot of manpower is saved, and the labor cost and the manufacturing cost of the assembly are reduced.
