Description

Technical Field

[0001] The invention belongs to the technical field of ship construction, and in particular relates to a PCTC ship upper section assembly method. Background Art

[0002] The original method of assembling the upper sections of the PCTC was to first load the bottom deck, then the side sections, and then the upper decks layer by layer. This method can ensure the efficiency and accuracy of the assembly of the sections, but because the side sections are higher and the center of gravity is higher, there is a greater risk of tipping if they are fixed by only one deck.

[0003] The PCTC ship's upper section consists of deck sections, columns, and side sections. Most of the structure is made of thin plates. Since there is no transverse bulkhead structure, it is mainly supported by columns, resulting in weak overall rigidity of the section. The reasonable assembly sequence of the section needs to consider the interference and deformation of the section hoisting, as well as the safety risk factors during the construction process. Summary of the invention

[0004] The present invention provides a method for assembling the upper sections of a PCTC ship, comprising the following steps:

[0005] S1: Install the bottom deck sections on the assembly platform;

[0006] S2: Install one layer of columns;

[0007] S3: Install one deck segment;

[0008] S4: Install the side sections;

[0009] S5: Repeat steps S2 and S3 until all deck sections are installed.

[0010] Further: also includes step S6: installing the upper deck section.

[0011] Further: Step S1: Install the bottom deck sections on the assembly platform, using temporary supports to assist the installation.

[0012] Further: Step S2: the width of the deck segment is the same as the width of the bottom deck segment.

[0013] Further: Step S2: There are two columns.

[0014] Further: Step S2: There are two columns, and the two columns are arranged at an interval.

[0015] Further: Step S2: the two columns are arranged at intervals along the width direction of the bottom deck segment.

[0016] Further: Step S4: installing the side section, the side section includes a port side and a starboard side, and the port side and the starboard side are respectively installed at the left and right ends of the deck section.

[0017] Further: Step S5: after installing a layer of columns, install a layer of deck segments above the columns, then install a previous layer of columns above the deck segments, and then install a previous layer of deck segments above the previous layer of columns.

[0018] The beneficial effects brought by the present invention are as follows:

[0019] It can be seen from the above scheme that the present invention provides a method for assembling the upper sections of a PCTC ship, which reduces the risk of the side sections tipping over during the assembly stage. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution in the embodiment of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiment of the present invention. Obviously, the described embodiment is a part of the embodiment of the present invention, not all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0030] like Figures 1 to 8 As shown, the present invention provides a method for assembling the upper sections of a PCTC ship, comprising the following steps:

[0031] S1: Install lower deck section 1 on the assembly platform;

[0032] S2: Install one layer of columns 2;

[0033] S3: Install one deck section 3;

[0034] S4: Install the side sections;

[0035] S5: Repeat steps S2 and S3 until all deck sections 3 are installed.

[0036] Further: also includes step S6: installing the upper deck section 6.

[0037] Further: Step S1: Installing the bottom deck section 1 on the assembly platform, using temporary supports to assist the installation.

[0038] Further: Step S2: Deck segment 3 has the same width as the bottom deck segment 1.

[0039] Further: Step S2: There are two columns 2.

[0040] Further: Step S2: There are two columns 2, and the two columns 2 are arranged at an interval.
