Description

Technical Field

[0001] The invention relates to a PCTC ship thin plate segment stacking method. Background Art

[0002] The thin plate section of PCTC ship (RoRo car carrier) is an important part of it. The thin plate section includes movable deck and fixed deck. There are many of them in the whole ship, and they occupy a large area. Due to the special structure of the thin plate section, there is only one horizontal deck frame and no bulkhead structure. Before the general assembly, multiple decks need to be stacked on the gantry pier to save the site area.

[0003] There are many thin plate sections in the PCTC ship. If each thin plate section is placed on the gantry pier separately, more gantry pier resources are required and a larger site area is occupied. In order to save site resources, affect the construction period of sections, facilitate section painting, and avoid structural deformation when sections are stacked, a PCTC ship thin plate section stacking method is proposed.

In addition, the terms "first", "second", and "third" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance.

[0046] The present invention will be further described below in conjunction with the accompanying drawings.

[0047] like Figure 1-14 As shown, a PCTC ship thin plate segment stacking method includes:

[0048] Tooling preparation;

[0049] The thin plates are stacked in sections;

[0050] The stacking of thin plates in sections includes movable deck stacking and fixed deck stacking.

[0051] like Figure 1 , 2 As shown in 3, tooling preparation includes:

[0052] Step 1: Select the portal pier 1. The size should ensure that the outermost strong structure of the segmented frame surface can fall on the portal pier. The portal pier 1 can be a 10m or 14m portal pier. The 14m portal pier can be modified from the 10m portal pier, with both ends extended by 2m. When selecting the portal pier, ensure that the outermost strong structure of the segmented frame surface can fall on the portal pier.

[0053] Step 2, prepare a plurality of flower stand piers 2 with a length of 1.0m×width of 1.0m×height of 1.2m;

[0054] Step three, select and prepare guardrails 3 and install them around the door frame pier 1.

[0055] like Figure 5 , 6 As shown in , 7 and 8, the stacking of movable decks includes:

[0056] Step 1, placing the first movable deck 4 on the portal pier 1;

[0057] Step 2: four flower rack piers 2 are arranged on the first movable deck 4, and two flower rack piers 2 at opposite corners are selected and welded to the first movable deck 4;

[0058] Step 3, placing the second movable deck 5 on the four flower rack piers 2;

[0059] Step 4: four flower rack piers 2 are set on the second movable deck 5 again, and two flower rack piers 2 at opposite corners are selected to be welded to the second movable deck 5;

[0060] Step 5: Place the third sliding deck 6 on the four flower rack piers 2.

[0061] The left and right side walls of the first movable deck 4 and the gantry pier 1 are welded with first cama 15 .

[0062] A first thin wooden board 7 is arranged on the upper end surface of each flower rack pier 2 , and first limiting plates 8 are arranged on both sides. The T-beams on the lower end surfaces of the second movable deck 5 and the third sliding deck 6 are connected to the first thin wooden board 7 .

[0063] When stacking, the main scale of the sections should be followed, with the sections with larger normal projection areas at the bottom and the sections with smaller areas at the top; the order of assembly and loading should be taken into consideration, with the sections assembled or loaded first at the top. Sections of the same layer or the same section should be stacked together; the movable deck sections involved in the assembly should be stacked first on the same layer and in the same annular seam. The movable deck sections that are loaded separately should be stacked on the same layer. The fixed deck sections should be stacked first on the same side. After the sections are leveled, they can be stacked for transportation in a maximum of 3 layers, and the projections of the center of gravity of each section should basically overlap.

[0064] The flower rack pier 2 and the door frame pier 1 are arranged symmetrically according to the center of gravity of the segment. The flower rack pier 2 and the door frame pier 1 both support the segmented strong structure. When stacking under static load, use wooden blocks to pad the segments to prevent relative sliding and ensure that the outfitting does not interfere. No protective railings are provided. It is strictly forbidden to stack large segments on small segments. When stacking, the upper and lower segments, wooden blocks, and the strong ribs supported by the flower rack pier 2 should be aligned as much as possible. Use turnbuckle bolts (hooks hooked into the binding holes) to fix the flower rack in four directions.

[0065] like Fig. 9 , 10 , 11, 12, 13, 14, the fixed deck stacking includes:

[0066] Step 1, placing a first fixed deck 9 on the portal pier 1;

[0067] Step 2, nine flower stand piers 2 are arranged on the first fixed deck 9;

[0068] Step 3, placing a second fixed deck 10 on the flower stand pier 2;

[0069] Step 4, nine flower stand piers 2 are arranged on the second fixed deck 10;

[0070] Step 5: placing the third fixed deck 11 on the flower rack pier 2.

[0071] The T-beam on the lower end surface of the first fixed deck 9 is connected to the portal pier 1 , and the second Cama 12 connects the portal pier 1 and the T-beam of the first fixed deck 9 .

[0072] A second thin wooden board 13 is arranged on the upper end surface of each flower rack pier 2 , and second limiting plates 14 are arranged on both sides. The T-beams on the lower end surfaces of the second fixed deck 10 and the third fixed deck 11 are connected to the second thin wooden board 13 .

[0073] When stacking, the main scale of the sections should be followed, with the sections with larger normal projection areas at the bottom and the sections with smaller areas at the top; the order of assembly and loading should be taken into consideration, with the sections assembled or loaded first at the top. Sections of the same layer or the same section should be stacked together; the movable deck sections involved in the assembly should be stacked first on the same layer and in the same annular seam. The movable deck sections that are loaded separately should be stacked on the same layer. The fixed deck sections should be stacked first on the same side. After the sections are leveled, they can be stacked for transportation in a maximum of 3 layers, and the projections of the center of gravity of each section should basically overlap.

[0074] The flower rack pier 2 and the portal frame pier 1 are arranged symmetrically according to the center of gravity of the section. The flower rack pier 2 and the portal frame pier 1 both support the section strong structure. When stacking under static load, use wooden blocks to pad the sections to prevent relative sliding and ensure that the outfitting does not interfere. No protective railings are provided. It is strictly forbidden to stack large sections on small sections. When stacking, the upper and lower sections, wooden blocks, and the strong ribs supported by the flower rack pier 2 should be aligned as much as possible. Use turnbuckle bolts (hook the binding holes) to fix the flower rack in four directions. When stacking, the fixed deck and the portal frame pier 1 must be padded, and the bow and stern ends between the sections must be firmly supported with supports (no less than 6 per layer).

[0075] The PCTC ship thin plate segment stacking method solves the existing problem that each thin plate segment is placed separately on the gantry pier, which requires a large number of gantry pier resources and occupies a large site area, by reasonably stacking and placing the movable deck and the fixed deck; it effectively saves the site area. At the same time, it prevents the structural deformation caused by the stacking of thin plate segments.
