Abstract

The invention discloses a pre-assembling method of a large-sized ship superstructure. The large-sized ship superstructure comprises a first deck section, a second deck section, a third deck section, afourth deck section, a fifth deck section, a navigation bridge deck section and a compass deck section, wherein the navigation bridge deck section comprises a first sub section and a second sub section; the pre-assembling method of the large-sized ship superstructure comprises the following steps of (1) hoisting the first deck section as a positioning section to perform position an upper tire; and (2) hoisting the second deck section, the third deck section, the fourth deck section, the fifth deck section, the first sub section, the second sub section and the compass deck section in sequenceto be positioned and mounted. According to the pre-assembling method of the large-sized ship superstructure, through pre-assembling construction method, the large-sized ship superstructure and a mainhull are constructed in a concurrent manner so that the mounting period in a dock is greatly shortened and the labor cost is greatly reduced; and through procedure advancing, a production node can besatisfied, and the construction period in the dock can be greatly shortened. The awkward situation of the construction progress is prevented from being affected due to limitation on a site; and the safety, quality, environment and economic benefit aspects are all greatly improved.

Description

technical field [0001] The invention relates to a pre-assembly method of a superstructure of a large ship. Background technique [0002] The construction and loading of large ships are generally carried out in the ship superstructure in the dock by means of separate loading on each deck (section). With the improvement of management of modern shipyards, the acceleration of production efficiency, the shortening of construction period, and the shortage of dock resources, this traditional construction method directly affects the construction period of the dock and the ship construction plan. Contents of the invention [0003] The purpose of the present invention is to provide a method for pre-assembly of superstructures of large ships in order to solve the above problems, which greatly reduces the installation period and labor costs in the dock. [0004] The purpose of the present invention is achieved like this: [0005] A pre-assembly method of a large ship superstructure ...
