Claim 0:
1. A corrugated plate for a liquefied gas storage tank of a transport device, comprising: a corrugated plate body, a longitudinal corrugation and a transverse corrugation that are formed on the corrugated plate body, and an intersection portion at an intersection of the longitudinal corrugation and the transverse corrugation, wherein a height of the longitudinal corrugation is less than a height of the transverse corrugation; and a maximum transverse dimension of the longitudinal corrugation is less than a maximum longitudinal dimension of the transverse corrugation,
wherein the intersection portion comprises a smooth central top surface and four drawbeads extending from the central top surface to the corrugated plate body; and the central top surface transitions to the drawbeads smoothly; wherein an overall extension direction of each of the drawbeads intersects a transverse direction, a longitudinal direction, and a height direction perpendicular to the corrugated plate body; and a height of the intersection portion is greater than the height of the longitudinal corrugation and the height of the transverse corrugation;
wherein the central top surface and the four drawbeads at least partially constitute a body segment of the intersection portion; the intersection portion further comprises two side segments; the two side segments are located at two ends of the body segment in the transverse direction respectively; and a height of each of the side segments is less than the height of the transverse corrugation and a height of the body segment,
wherein each of the drawbeads has a ridge extending from a top to a bottom thereof; a width of each ridge remains unchanged in a direction from the top to the bottom; and a trench parallel to the ridge and extending from the top to the bottom of the drawbead is provided between the ridge and the side segment.
