The invention belongs to the technical field of airplane structure strength test bearing cross beam design, and particularly relates to a combined type large-span cross beam structure. The combined type large-span cross beam structure comprises multiple sections of short-span cross beams, wherein the cross sections of the short-span cross beams are I-shaped and are mutually butted to form a large-span cross beam; multiple pairs of web connecting plates, wherein each pair of web connecting plates is correspondingly connected to the two sides of the butt joint part of the two short-distance cross beam webs at one position; multiple pairs of upper edge strip connecting plates, wherein each pair of upper edge strip connecting plates is correspondingly connected to one pair of web plate connecting plates and is connected to the butt joint part of the upper edge strips of the corresponding two sections of short-span cross beams; multiple pairs of lower edge strip connecting plates, wherein each pair of lower edge strip connecting plates is correspondingly connected to one pair of web plate connecting plates and is connected to the butt joint part of the corresponding two sections of short-span cross beam lower edge strips; and multiple pairs of reinforcing rib plates, wherein each pair of reinforcing rib plates is correspondingly connected to one pair of web connecting plates and is connected with one corresponding pair of upper edge strip connecting plates and lower edge strip connecting plates.
