Double-Layer Hollow Plate Structure

Abstract

A double-layer hollow plate structure, comprising a hollow plate, wherein the hollow plate is a double-layer wall structure and a cavity is provided between the double-layer walls; both side walls of the hollow plate are regularly provided with a plurality of corresponding crisscrossed grooves in units, and each groove is gradually deepened in an arc shape in the depth direction until it is connected with the corresponding groove on the opposite side at the intersection. The arc-shaped grooves in the depth direction that are crisscrossed and distributed have a reinforcing effect on the wall surface. The grooves on the two side walls are connected together at the corresponding intersections to support the two walls. Many intersections of the grooves on the two side walls are connected into many supporting points to support the entire two wall surfaces, so that the grooves on the two wall surfaces can be strengthened.
