Description

Technical Field

[0001] The present invention relates to the technical field of shipbuilding, and in particular to an integrated construction method for the transverse bulkhead assembly of a container ship. Background Art

[0002] The water stop flat iron is a common protective device, often used in positions such as the superstructure and deck of a ship that require waterproof and oil-proof protection. The water stop flat iron is usually a long strip of steel plate, generally assembled around the platform plate, equipment base, and deck surface in the form of fillet welding. The width of the flat iron at the top plate of the transverse bulkhead is generally 100 - 200 (unit not specified), and the thickness is generally 8mm. The width and thickness of the flat iron can be adjusted according to relevant design specifications such as those of the classification society. The water stop flat iron belongs to the category of ship outfitting parts and needs to be welded after the construction of the hatch coaming of the transverse bulkhead is completed or installed after the transverse bulkhead is launched in the dry dock. After installation, inspection and reporting work such as flaw detection is carried out according to requirements.

[0003] Currently, during the shipbuilding process, the water stop flat iron needs to be installed additionally as an outfitting part. After the production of the compartment section is completed, the water stop flat iron is positioned at the top plate of the compartment and fixed by spot welding and then welded. This results in an extended production cycle of the section and affects subsequent production.

[0004] When the water stop flat iron outfitting part is positioned and welded on the top plate, both corner joints of the flat iron need to be welded. And the compartment is in a lying state. As Figure 1 shown, at this time, the top plate 11 is in a vertical state, the long strip-shaped water stop flat iron 31 is horizontally arranged and connected to the upper and lower edges of the vertically arranged top plate 11 respectively. Therefore, the lower joint at the connection between the water stop flat iron 31 and the top plate 11 needs to be welded in the overhead position. There are potential safety hazards in the welding forming quality and on-site construction safety. Each compartment section has long-distance overhead welding work for two corner joints, and the overhead welding working hours consumed are 4 times that of the flat welding at the same distance. There are also risk factors such as welding sparks spilling.

[0005] In addition, taking one end bulkhead of the transverse bulkhead as the construction base surface for construction, as Figure 2 、 Figure 3 shown, when installing the top plate, since a part extends out of the transverse bulkhead plate 21, that is, the upper and lower edges of the vertically arranged top plate 11 protrude from the transverse bulkhead plate 21, in order to keep the hatch coaming of the transverse bulkhead horizontally constructed, a groove needs to be cut on the jig to place the protruding part 101. However, the upper jig position and orientation of each transverse bulkhead are not fixed, which will result in grooves being cut in multiple areas on the jig, affecting the use of the jig and consuming additional working hours and cutting costs. Summary of the Invention

[0006] In view of the above-mentioned disadvantages of the prior art, the purpose of the present invention is to provide a new integrated construction form for the transverse bulkhead assembly, using this integrated construction form to replace the traditional water-stop flat bar fitting with the hull structure, so as to realize the structuring of the water-stop flat bar. Through the structured assembly design, the extra workload generated by the installation of the traditional water-stop flat bar during ship construction is reduced, the corresponding manufacturing cost is effectively reduced, the sectional manufacturing / block erection efficiency is improved, and the purpose of improving the shipbuilding production capacity is achieved.

[0007] To achieve the above and other related purposes, the present invention provides an integrated construction structure for the transverse bulkhead assembly of a container ship. The transverse bulkhead assembly includes a transverse wall plate perpendicular to the bow-stern direction and a top plate arranged horizontally. The transverse wall plate includes a front bulkhead and a rear bulkhead arranged in the bow-stern direction and parallel to each other. The upper edges of the front bulkhead and the rear bulkhead protrude above the upper surface of the top plate to form a protruding part for intercepting fluid. The front edge and the rear edge of the top plate are respectively fitted to the surfaces of the front bulkhead and the rear bulkhead.

[0008] A longitudinal girder frame is provided between the front bulkhead and the rear bulkhead, and the longitudinal girder frame is perpendicular to the front bulkhead and the rear bulkhead.

[0009] Optionally, the transverse bulkhead assembly is divided into a first middle assembly and a second middle assembly connected in the left-right direction, and the protruding parts of the first middle assembly and the second middle assembly are flush.

[0010] Optionally, it further includes a third middle assembly, the third middle assembly is connected to the lower edge of the second middle assembly, and the left and right edges of the third middle assembly are flush with the second middle assembly.

[0011] Optionally, the height of the protruding part is greater than 50 mm.

[0012] The present invention also provides a construction method for the above-mentioned integrated construction structure, including the following steps:

[0013] S1: Divide the transverse bulkhead assembly into a first middle assembly, a second middle assembly, and a third middle assembly. Among them, the first middle assembly and the second middle assembly are connected in the left-right direction, and the third middle assembly is connected to the lower edge of the second middle assembly;

[0014] S2: Construct the first middle assembly;

[0015] First, perform panel welding. Assemble and weld angle steel on the surface of the rear bulkhead near the front side to form a first rear wall middle assembly;

[0017] Next, the first front wall middle assembly is turned over and buckled onto the first rear wall middle assembly to form a first middle assembly; wherein the longitudinal girder frame is sandwiched between the front bulkhead and the rear bulkhead.

[0018] Optionally, the method further includes the following steps:

[0019] S3: Carry out the construction of the second assembly;

[0020] First, the panels are assembled and welded, and angle steel is assembled and welded on the surface of the rear bulkhead near the front side to form the second rear wall assembly;

[0021] Next, take the front bulkhead as the base surface, lay out the panels on the surface of the front bulkhead near the rear side, assemble and weld the angle steel and rib plates, assemble the longitudinal girder frame, and connect the longitudinal girder frame with the front bulkhead vertically. Assemble the sub-assembly to form the second front wall middle assembly, which includes the main deck sub-assembly and the platform plate sub-assembly arranged at both ends of the longitudinal girder frame.

[0022] Next, the second front wall middle assembly is turned over and buckled onto the second rear wall middle assembly to form a second middle assembly; wherein the longitudinal girder frame is sandwiched between the front bulkhead and the rear bulkhead.

[0023] As described above, the present invention provides an integrated construction structure and construction method for assembling transverse bulkheads of container ships. The integrated construction structure improves the structure of the transverse wall plate so that the upper edge of the transverse wall plate protrudes from the surface of the top plate to form a protrusion to replace the water-blocking flat iron, thereby eliminating the need for welding of the flat iron and avoiding the need for cutting of the tire frame during horizontal construction. The entire construction process eliminates the need for welding of water-blocking flat iron outfitting parts, which greatly reduces the amount of welding material, saves the direct material cost of water-blocking flat iron outfitting parts and welding materials, saves material investment and auxiliary costs, and can also reduce kinetic energy consumption and save indirect costs for scaffolding and paint repairs. At the same time, eliminating the water-blocking flat iron can avoid high-altitude operations in the later stage from the source of the design, greatly reduce construction risks, and achieve inherent safety. In addition, through reasonable central assembly division, the integrated construction of transverse bulkhead assembly can reduce the assembly cycle by about 5 to 7 days (calculated from the processes of segmentation to external tire loading, tire frame leveling, marking, positioning, hatch coaming assembly, welding, grinding, repainting, inspection, etc.), improve the efficiency of segment production / overall segment assembly, and achieve the purpose of improving shipbuilding capacity.

Detailed implementation mode

[0040] The following uses specific specific examples to illustrate the implementation mode of the present invention. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification. The present invention can also be implemented or applied through other different specific implementation modes. The details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of the present invention.

[0041] When detailing the embodiments of the present invention, for the convenience of description, the cross-sectional views showing the device structure will be enlarged locally in a non-general proportion, and the schematic diagrams are only examples, and they should not limit the scope of protection of the present invention here. In addition, in actual production, three-dimensional spatial dimensions including length, width and depth should be included.

[0042] For the convenience of description, spatial relationship terms such as "below", "beneath", "lower than", "under", "above", "on" etc. may be used here to describe the relationship between an element or feature shown in the drawings and other elements or features. It will be understood that these spatial relationship terms are intended to include other directions of the device in use or operation in addition to the directions depicted in the drawings. In addition, when a layer is referred to as being "between" two layers, it can be the only layer between the two layers, or there can also be one or more intervening layers. As used herein, "between... and..." means including the endpoint values.

[0043] In the context of the present application, the structure in which the first feature is "above" the second feature described may include an embodiment in which the first and second features are formed in direct contact, and may also include an embodiment in which additional features are formed between the first and second features, such that the first and second features may not be in direct contact.

[0044] It should be noted that the illustrations provided in this embodiment only illustrate the basic concept of the present invention in a schematic manner.

The type, quantity and proportion of each component in its actual implementation can be arbitrarily changed, and the component layout type may also be more complex.

[0045] The current angular connection form of the diaphragm deck plate and the transverse bulkhead plate is designed such that the deck plate extends a certain length in the fore-and-aft direction to form a protruding part, and the upper edges of the plates of the front and rear transverse bulkheads of the compartment are angularly connected to the lower surface of the deck plate. As Figures 1 to 3 shown, this construction form requires additional welding of strip-shaped water retaining flat irons on the upper surface of the deck plate. At the same time, during the construction in the lying state, grooves need to be cut on the jig to place the protruding part, consuming additional man-hours and cutting costs. In this application, the structure of the transverse bulkhead plate is improved so that the upper edge of the transverse bulkhead plate protrudes above the surface of the deck plate to form a protruding part to replace the water retaining flat iron, which not only eliminates the welding of the flat iron but also avoids the groove trimming during the lying construction.

[0046] Embodiment 1

[0047] As Figures 4 to 6 shown, this embodiment provides an integrated construction structure for the transverse diaphragm assembly of a container ship.

[0048] The transverse diaphragm assembly includes a transverse bulkhead plate 21 perpendicular to the fore-and-aft direction and a deck plate 11 arranged horizontally. The transverse bulkhead plate 21 includes a front bulkhead and a rear bulkhead arranged in the fore-and-aft direction and parallel to each other. The upper edges of the front bulkhead and the rear bulkhead both protrude above the upper surface of the deck plate to form a protruding part 201. The front edge and the rear edge of the deck plate 11 are respectively fitted to the surfaces of the front bulkhead and the rear bulkhead. Here, the protruding part 201 is used instead of the water retaining flat iron to intercept fluids and play a role in waterproofing and oil prevention.

[0052] Based on the above assembly division, this embodiment also provides an integrated construction method for the transverse diaphragm assembly of a container ship, including the following steps:

[0053] S1: Divide the transverse diaphragm assembly into a first middle assembly 100, a second middle assembly 200, and a third middle assembly 300, where the first middle assembly 100 and the second middle assembly 200 are connected in the left-right direction, and the third middle assembly 300 is connected to the lower edge of the second middle assembly 200;

[0054] S2: AsFigures 7 to 10 As shown, the construction of the first intermediate assembly 100 is carried out;

[0055] First, panel welding is carried out. Angle steel is assembled and welded on the surface of the rear bulkhead 111 near the front side to form the first rear wall intermediate assembly;

[0056] Next, with the front bulkhead 112 as the base surface, panel welding is carried out on the surface of the front bulkhead 112 near the rear side. Angle steel and stiffeners are assembled and welded; the longitudinal girder frame 113 is assembled, and the longitudinal girder frame 113 is perpendicularly connected to the front bulkhead 112; small assemblies are assembled to form the first front wall intermediate assembly 120. The small assemblies include the main deck small assembly 114 and the second deck platform plate small assembly 115 arranged at both ends of the longitudinal girder frame. The small assemblies, the longitudinal girder frame 113, and the front bulkhead 112 are perpendicular to each other.

[0057] Next, the first front wall intermediate assembly 120 is turned over and buckled on the first rear wall intermediate assembly to form the first intermediate assembly 100. Among them, the longitudinal girder frame 113 is clamped between the front bulkhead 112 and the rear bulkhead 111, and the upper edges of the front bulkhead and the rear bulkhead of the first intermediate assembly 100 both protrude from the top plate to form the protruding part 201.

[0058] S3: As Figures 11 to 14 shown, the construction of the second intermediate assembly 200 is carried out;

[0059] First, panel welding is carried out. Angle steel is assembled and welded on the surface of the rear bulkhead 211 near the front side to form the second rear wall intermediate assembly;

[0060] Next, with the front bulkhead 212 as the base surface, panel welding is carried out on the surface of the front bulkhead 212 near the rear side. Angle steel and stiffeners are assembled and welded; the longitudinal girder frame 213 is assembled, and the longitudinal girder frame 213 is perpendicularly connected to the front bulkhead 212; small assemblies are assembled to form the second front wall intermediate assembly 220. The small assemblies include the main deck small assembly 214 and the platform plate small assembly 215 arranged at both ends of the longitudinal girder frame. The small assemblies, the longitudinal girder frame, and the front bulkhead are perpendicular to each other.

[0061] Next, the second front wall intermediate assembly 220 is turned over and buckled on the second rear wall intermediate assembly to form the second intermediate assembly 200.

The integrated construction structure improves the structure of the transverse bulkhead plate, making the upper edge of the transverse bulkhead plate protrude from the surface of the top plate to form a protruding part to replace the water stop flat iron.

The welding of the water stop flat iron fitting is omitted throughout the construction process, the welding quantity is greatly reduced, the direct material costs of the water stop flat iron fitting and welding materials are saved, the material input and auxiliary costs are saved, and the indirect costs of dynamic energy consumption, scaffolding erection, and paint repair can also be reduced. At the same time, the cancellation of the water stop flat iron can avoid high-altitude operations in the later stage from the design source, greatly reduce the construction risk, and achieve intrinsic safety. In addition, through reasonable division of the intermediate assembly, the integrated construction of the transverse bulkhead assembly can reduce the large assembly cycle by about 5 to 7 days (calculated from processes such as the section to the outer field jig, jig leveling, marking, positioning, hatch coaming assembly, welding, grinding, paint repair, and inspection), improve the efficiency of section fabrication / general block erection, and achieve the purpose of improving the shipbuilding production capacity.
