Embodiment Construction

[0019] The technical solution of the present invention is further described below in conjunction with specific embodiments:

[0020] A long-span deck flatness control process includes a segmented structure form, a construction process, a precision control method, and deformation correction measures.

[0021] The segmented structure is aimed at the structural form of the main deck 1 of the ship. The main deck 1 adopts a longitudinal skeleton structure design, and the longitudinal skeleton structure is divided into a longitudinal structure and a transverse structure. The transverse structure uses welded T-profiles with a spacing of 2.4m.

[0022] The construction process includes pre-construction preparation, tire frame 2 manufacturing, main deck 1 planking and welding, frame marking and assembly, frame welding, completion measurement, segmental turning welding, deformation correction, submission for acceptance, and segmental completion barge.

[0023] The truss-type tire frame...

Abstract

The invention relates to a flatness control process for a large-span deck, and relates to the technical field of shipbuilding. The process comprises a sectional structure form, a construction process,a precision control method and a deformation correction measure. The process solves the problem of precision control of a ship deck section with a large main size from the perspective of a construction process, is suitable for flatness and precision control of ship section construction with a large main size, and is clear in process, clear in key point, proper in method and high in construction efficiency.

Description

technical field [0001] The invention relates to the technical field of shipbuilding, in particular to a large-span deck smoothness control process. Background technique [0002] In recent years, with the rapid development of the shipping industry, the performance requirements for ships are getting higher and higher, especially for large ships such as container ships, which are expensive and carry a large amount of cargo. In the construction of these large ships, hull segmentation and steel structure module production will be involved, and the general assembly and paneling process between segments needs to control the flatness of the plate joints, especially for hull segments with large spans. And the overall precision control is difficult. If the main size of the segment is changed because of this, that is, it is divided into multiple blocks for fabrication and then synthesized into a whole, which will increase the time for lifting and welding together, and make the work ef...
