Abstract
The present disclosure provides a corrugated plate and a liquefied gas storage container having the same. The corrugated plate comprises a plate body, a first corrugation and a second corrugation orthogonal to each other, and an intersection structure formed at the intersection position. The first corrugations are higher than the second corrugations. The intersection structure comprises a top portion, ridges, and recessed portions. The recessed portions consist of four, each located in one quadrant, formed on the outer side of the first corrugation and sandwiched between a first crest of the first corrugation and a corresponding ridge, and concaved inward relative to the outer side. According to the present disclosure, the intersection structure ensures that the upper and lower surfaces at the intersection position have uniform line lengths, thereby achieving uniform thickness, avoiding excessive thinning, and providing improved structural strength and fatigue resistance.
