Large-span arched design structure with honeycomb type interlayer

The invention discloses a large-span arch-shaped design structure with a honeycomb type interlayer. The large-span arch-shaped design structure comprises an inner arch-shaped plate and an outer arch-shaped plate, an interlayer cavity is reserved between the outer arched plate and the inner arched plate; the honeycomb type interlayer is arranged in the interlayer cavity and comprises a plurality of honeycomb cell elements clamped between the inner arched plate and the outer arched plate; the honeycomb cell element comprises a cylinder body, a supporting leg and a connecting piece, and the outer end of the connecting piece on the end face of the cylinder body is clamped on the first guide rail and the second guide rail respectively; and the reinforcing mechanism is connected to the connecting piece and is used for associating the honeycomb cell elements and elastically reinforcing the connection between the honeycomb interlayer and the inner arched plate as well as the outer arched plate.
