Double-hull ship wall structure in which the access opening from the cell to the cell through the wall-layer connection plate is provided in the longitudinal zigzag shape

摘要

In double layered ship wall vessels 20, 22, 24 and 28 they have two transversely spaced longitudinal wall layers 32 and 34 and a wall layer connection plate 38, (36) to one of the longitudinal edges (34, 32) welded to one of the longitudinal edges (32, 34) of the plate edge to the plate edge joint (36) With the opposite longitudinal edges to divide the space surrounded by the wall structure into a plurality of cells 52 that are sealed at the opposite ends by the transverse bulkheads 44 and the access openings 30 from the cells to the cells Longitudinally staggered and located near the cell end. So that the air is forcedly forced through the entire space enclosed within the wall structure 56 and the workers falling while ascending from one cell 52 through the access opening 30 to the other by the access opening 30 Only the vertical length of the two interconnected cells 52 is dropped.
