Description

TECHNICAL FIELD

[0001] The present application relates to the field of shipbuilding technology, and particularly relates to a shed for improving construction conditions of a flat section and a method. BACKGROUND

[0002] Due to the structural characteristics of large ships, the line type of the section plate in the bow and stern regions changes greatly, and the section structure in the middle of the ship and the ship side is relatively flat. At present, due to the limitation of the infrastructure of the shipyard, the construction of the relatively flat section needs to be carried out in the open air to save the workshop position resources.

[0003] However, this construction method is greatly affected by the outdoor weather. In rainy days, water will form in the section, and the water needs to be pumped out and dried before further electric welding construction, which will delay the construction progress. In the summer high temperature season, the section is not sheltered, the working environment of workers is poor, and the work efficiency is low. After the conventional shed is covered to the top of the section, the space under the shed will be relatively closed, and if polishing work is performed in the space, the dust in the space will be difficult to dissipate.
