For example, the bottom can include directly below, lower left, lower right, lower front, and lower back, etc.

[0036] In the process of ship section construction, in order to make the assembly process simple and save time and effort, and improve the overall assembly efficiency of the section, Figure 1-Figure 5 As shown, the present invention provides a method for assembling a ship in sections. The method for assembling a ship in sections comprises the following steps:

[0037] S1, assembling the outer panel assembly 6, the longitudinal wall panel assembly and the transverse wall panel assembly, marking the first rib inspection line 61 on the outer panel assembly 6, and setting up a workbench;

[0038] S2. Draw a segmented cross reference line on the workbench, and use the cross reference line as the standard to draw the second rib inspection line, the first installation position line 2 of the longitudinal wall panel assembly, and the second installation position line 3 of the transverse wall panel assembly on the workbench;

[0039] S3, hoisting the longitudinal wall panel assembly to the first installation position line 2, adjusting the longitudinal wall panel 4 in the longitudinal wall panel assembly to be in a vertical state, positioning and supporting the longitudinal wall panel assembly, hoisting the transverse wall panel assembly to the second installation position line 3, adjusting the transverse wall panel 5 in the transverse wall panel assembly to be in a vertical state, positioning and supporting the transverse wall panel assembly;

[0040] S4. Lift the outer panel assembly 6 onto the workbench and adjust and install it. The second rib inspection line on the workbench is consistent with the marked first rib inspection line 61. Assemble the cross wall assembly on the outer panel assembly 6, and adjust the half width of the open part of the outer panel assembly 6 according to the design requirements to support and position the outer panel assembly 6.

[0041] By setting a cross reference line to determine the second rib inspection line, the first installation position line 2 and the second installation position line 3, it is convenient to position the transverse wall panel assembly and the longitudinal wall panel assembly. By marking the first rib inspection line 61 on the outer panel assembly 6, during the installation of the outer panel assembly 6, the first rib inspection line 61 and the second rib inspection line are consistent to position the outer panel assembly 6. The above method can make the assembly process simple and save time and labor, and improve the overall assembly efficiency of the segment.

[0042] In some embodiments, in step S1, the outer panel assembly 6, the longitudinal wall panel assembly and the transverse wall panel assembly that have been welded and assembled are corrected. Through the correction, it is possible to ensure that the outer panel assembly 6, the longitudinal wall panel assembly and the transverse wall panel assembly meet the design requirements, and in the subsequent positioning and assembly process, the positioning and assembly accuracy is guaranteed.

[0043] In some embodiments, in step S1, the upper tire plate 11 is assembled and welded on the segmented tire frame 1 to form a workbench. The workbench is designed according to the segmented structure to facilitate the subsequent positioning and assembly of the outer plate assembly 6, the longitudinal wall assembly and the transverse wall assembly.

[0044] In some embodiments, a first rib inspection line 61 is marked on the outer panel assembly 6 by using sample punching points and paint. By using sample punching points and paint marking, it is convenient for construction personnel to observe when positioning the outer panel assembly 6 later, thereby ensuring the accuracy of construction.

[0045] In some embodiments, in step S2, a laser theodolite is used to mark a segmented cross reference line on the table. The use of a laser theodolite facilitates the rapid marking of the segmented cross reference line, eliminates the need for the installation of a wire drawing rack of traditional process equipment, saves materials and steel wires for the wire drawing rack, saves management work for the tooling rack, etc. Moreover, the laser theodolite is not affected by the external environment, and is convenient for subsequent marking and positioning assembly operations.

[0046] In some embodiments, in step S3, a first parallel line is drawn on the table surface according to the offset set distance of the first installation position line 2, the first parallel line is parallel to the first installation position line 2, and is located on the non-structural surface side of the longitudinal wall panel assembly, when the longitudinal wall panel 4 is parallel to the vertical plane where the first parallel line is located, the longitudinal wall panel 4 is in a vertical state. In this way, the verticality of the longitudinal wall panel 4 can be quickly adjusted to ensure that the longitudinal wall panel 4 is in a vertical state.

[0047] In some embodiments, in step S3, a second parallel line is drawn on the table according to the offset set distance of the second installation position line 3, the second parallel line is parallel to the second installation position line 3, and is located on the non-structural surface side of the transverse wall panel assembly, when the longitudinal wall panel 4 is parallel to the vertical plane where the second parallel line is located, the longitudinal wall panel 4 is in a vertical state. In this way, the verticality of the transverse wall panel 5 can be quickly adjusted to ensure that the transverse wall panel 5 is in a vertical state.

[0048] In some embodiments, a line thrower is used to align with the first parallel line or the second parallel line to simulate a vertical plane. Since the line thrower has the characteristic of continuous line throwing, the vertical plane can be effectively simulated by the line thrower, and the line thrower is not affected by the external environment, which is convenient for detecting and adjusting the verticality of the longitudinal wall plate 4 and the transverse wall plate 5. In order to facilitate the installation of the line thrower, a simple bracket can be made to fix the line thrower.

[0049] In some embodiments, in step S4, the second rib inspection line is extended and marked to the ground where the segment is located, and the first rib inspection line 61 is adjusted to be consistent with the second rib inspection line to adjust and assemble the outer panel assembly 6. In this way, the assembly and positioning of the outer panel assembly 6 can be prevented from being affected by the internal longitudinal wall panels 4 and transverse wall panels 5 or the narrow space, so that the outer panel assembly 6 can be quickly positioned.

[0050] In some embodiments, in step S4, the outer plate installation position line of the outer plate assembly 6 is consistent with the height of the deck or platform. Through the above definition, the installation height position of the outer plate can be determined.

[0051] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the embodiments of the present invention. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the embodiments here.
