The invention relates to a rod system and boxboard modular combination bearing structure which is externally surrounded by a rod system and internally of a boxboard type structure composed of layer boards and cross-shaped vertical boards. Comprising an upper-layer plate, a middle-layer plate, a lower-layer plate, a vertical plate, a first support, a second support, a rod piece, a rod end connector, a double-thread screw and an angle bead. A plurality of groups of rod system structures are uniformly distributed between the upper-layer plate and the middle-layer plate, between the middle-layer plate and the lower-layer plate in the circumferential direction of the edges of the layer plates, the number of the rod system structures is adjusted according to the load magnitude, each group of rod system structures comprises rod pieces and is arranged in a herringbone shape, and each group of rod system structures is connected with the upper-layer plate and the lower-layer plate through a first support, a rod end connector and a pin shaft and connected with the middle-layer plate through a second support and a rod end connector; and the upper-layer plate, the middle-layer plate and the lower-layer plate are fixedly connected with the vertical plates through angle shafts. The technical requirements for bearing and light weight of a main structure of an aerospace craft are met, and the bearing reliability of the structure is improved while structural configuration and light weight are achieved.
