Abstract
The utility model provides a split type ethylene cold box steel structure device. The split type ethylene cold box steel structure device comprises at least four side wall plate sheet assemblies, a bottom plate sheet assembly and a top plate sheet assembly which are mutually independent and can be welded and spliced to form a closed box body. Each side wall plate piece assembly comprises a first rectangular frame formed by welding a plurality of stand columns and a plurality of first cross beams, a plurality of inclined struts welded in the first rectangular frame, and a plurality of panel reinforcing ribs welded between the stand columns and the first cross beams. And the first panel covers and is welded on the first rectangular frame and the panel reinforcing ribs. According to the utility model, the large cold box is divided into a plurality of independent plate assemblies with the sizes within the standard transportation limit, so that the bottleneck problem of overall transportation of oversized parts is solved, and the transportation cost and the safety risk are obviously reduced.
