A kind of construction method of ship deck general section

Abstract

The invention discloses a ship deck block building method. A cargo hold block and deck panels are supplied, a plurality of supporting columns are arranged on an inner base plate of a cabin of the cargo hold block, the deck panels are lifted to the cargo hold block, the multiple supporting columns are supported to the positions, likely to deform, of the deck panels, and the multiple deck panels arewelded so that the deck panels can be connected to form a deck block on the cargo hold block. The multiple supporting columns are arranged on the inner base plate of the cabin of the cargo hold blockin advance, the supporting columns are supported to the positions, likely to deform, of the deck panels, after the deck panels are lifted and welded and a lengthened row is disassembled, an extra effective supporting structure is arranged for supporting the deck blocks, the phenomenon that the assembled and formed deck block sinks and deforms is effectively avoided, the horizontal precision of the deck surface of the deck block is ensured, the building precision of a later hatch coaming is improved, repairing and correcting workloads are reduced, and the machining speed is increased.

Description

technical field [0001] The invention relates to the technical field of ship manufacturing, in particular to a method for building a general deck section of a ship. Background technique [0002] Carrying ships such as ore carriers are usually equipped with hatch coaming, which is set on the general deck section, and the corresponding hatch coaming on the general deck section is provided with hatches for the entry and exit of goods. The general deck section is usually divided into multiple decks. segment assembly. Usually the size of the hatch is very large, and there is no transverse bulkhead structural support below when the deck section is positioned, assembled and welded at this position, only relying on the side of the ship or the long row of reinforcement below the deck (the long row of reinforcement is in the The tooling structure set up to prevent the deformation of the deck section when hoisting the deck section needs to be dismantled) to fix it later. When the deck ...

Problems solved by technology

Usually the size of the hatch is very large, and there is no transverse bulkhead structural support below when the deck section is positioned, assembled and welded at this position, only relying on the side of the ship or the long row of reinforcement below the deck (the long row of reinforcement is in the The tooling structure set up to prevent the deformation of the deck section when hoisting the deck section needs to be dismantled) to fix it later. When the deck section is tack welded to assemble the deck section and the reinforced long row is removed, the hatch enclosure will be damaged. The lower deck section sinks, and the sunken deck section makes it extremely difficult to control the horizontal accuracy of the deck surface, which brings great difficulties to the subsequent hatch coaming segmental construction, and it is difficult to meet the accuracy requirements of the hatch coaming platform
