Large container ship wing bridge block integrated construction method

Abstract

The invention discloses a large container ship wing bridge block integrated construction method. The method comprises the following steps that 1, a straight universal moulding bed is arranged, whereinthe straight universal moulding bed used for reverse integrated construction of superstructure wing bridge blocks and bridge deck blocks of a large container ship is arranged on a total configurationplatform; 2, steel plates are reversely laid, wherein with the deck surfaces as the reference surfaces, the steel plates used for construction of the left and right deck surfaces of the wing bridge blocks and the bridge deck blocks are laid on the straight universal moulding bed respectively, and a union melt welding way is adopted for welding. By means of the method, the situation of separate construction of the wing bridge blocks and total assembly of hoisting can be avoided, the turnover times of the blocks and the using number of gantry cranes can be reduced, the overall precision of theblocks is better controlled, the product quality is improved, the production cost is saved, and the production efficiency is improved. Aerial work can be avoided, the trouble that scaffolds are set upat a high altitude is omitted, and the operation safety is increased.

Description

technical field [0001] The invention relates to a construction method, in particular to a segmented and integrated construction method for a wing bridge of a large container ship. Background technique [0002] At present, the wing bridge segments located on the left and right sides of the superstructure driving deck segment on large container ships are constructed separately, and the main group is hoisted independently after the construction is completed. [0003] In the separate construction process of the wing bridge sections, special tire frames need to be arranged, which wastes materials and is not conducive to the reasonable arrangement of the construction site; the other sections have to be turned over many times, and the accuracy requirements are difficult to guarantee. In the process of hoisting the wing bridge section by itself, it is necessary to work at heights and set up complex scaffolding, which is quite dangerous. Therefore, the research on the segmented and ...
