Summary: | The utility model relates to an inner tensioning prestressed concrete double-layer variable-cross-section panel box-shaped structure. A variable-cross-section panel is arranged in a direction parallel to the cross section, a double-layer box-shaped cross section is formed, the span range of the variable-cross-section panel is 7 to 36m, after annular prestressed ribs are arranged in a peripheral component, a parabola prestressed rib is arranged in the middle layer flat plate, tensioning grooves are preserved at the side surface of a component arranged inside the structure, after the concrete installation, all sections of one prestressed rib are sequentially connected in an end-to-end way and are tensioned at the tensioning groove parts through a middle anchor, and then, the tensioning grooves are sealed and blocked. The inner tensioning prestressed concrete double-layer variable-cross-section panel box-shaped structure is characterized in that the tensioning grooves are preserved at the side surface of the com |
