Description

Technical Field

[0001] The present invention relates to the technical field of shipbuilding, and particularly to a construction method for the reference line of the interior fitting-out of a cruise ship. Background Art

[0002] The construction stage of a large cruise ship is divided into the hull, outfitting and interior fitting-out stages. The hull stage is further divided into sectional, sub-assembly and erection. The interior fitting-out of a cruise ship is mainly subcontracted. Different from traditional procurement, it relies on subcontractors to conduct the whole-process management from conceptual design, basic design, materials, construction to final delivery. The construction of each subcontractor is relatively independent, and there are interference problems during the interior fitting-out construction, including the interference of the structure to the interior fitting-out, the interference of the outfitting to the interior fitting-out, and the construction interference between subcontractors. Therefore, there is an urgent need to unify the construction method of the reference line for the interior fitting-out of a cruise ship.

[0003] In the prior art, only in the hull stage, the R.C. reference line and the R.L. reference line are automatically marked on the main board splicing plate, and the sub-assembly needs to be leveled in the subsequent manufacturing stage. During the leveling process, shrinkage will occur at the leveling position. In some places with a large shrinkage amount, the originally marked R.C. reference line and R.L. reference line may shift and cannot be used in the subsequent interior fitting-out stage. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to overcome the defect that only the R.L. reference line and the R.C. reference line are marked in the hull stage in the prior art, and the R.L. reference line and the R.C. reference line cannot be used in the subsequent interior fitting-out stage, and to provide a construction method for the reference line of the interior fitting-out of a cruise ship.

[0005] The present invention solves the above technical problem through the following technical solutions:

[0006] A construction method for the reference line of the interior fitting-out of a cruise ship includes the following steps:

[0007] S100: In the stairway area of the cruise ship, in the public area spanning multiple sub-assemblies or main vertical zones, and in the unit cabin area, take the distance between the two side bulkheads in the ship width direction for centering, and mark the R.C. reference line on the deck in the area.

[0008] S200: In the stairway area of the cruise ship, in the public area spanning multiple sub-assemblies or main vertical zones, and in the unit cabin area, take the bulkhead or side bulkhead in the area as the reference in the ship length direction and the ship width direction, and respectively mark the R.L. reference line on the deck in the area.

[0009] S300: Take the highest point of the deck in the non-mechanical area of the cruise ship as the reference, and mark the R.H. contour line on the column or side bulkhead after translating upward by a preset first distance.

[0010] In this solution, after the cruise ship completes the hull construction and outfitting, it needs to enter the interior fitting-out stage. The areas involved in the interior fitting-out stage include the cruise ship stairway area, the public areas across multiple sections or main vertical zones, and the unit cabin areas. In each of the above areas, the distance between the two side bulkheads is measured separately in the ship width direction, and the midpoint of this distance is determined. The R.C. reference lines are respectively marked on the decks of the respective areas. Using the bulkheads and enclosures within the area as a reference in the ship length direction or ship width direction, the R.L. reference lines are respectively marked on the decks of the respective areas. Taking the highest point of the deck in the non-mechanical area of the cruise ship as a reference, after translating upward by a certain distance, the R.H. contour lines are marked on the columns or bulkheads. By marking the corresponding reference lines in the length, width, and height directions in the above areas, each subcontractor can construct relatively independently according to the reference lines during the interior fitting-out stage, without interference between each other, ensuring the smooth progress of the interior fitting-out project. This method is simple to operate, has relatively high safety and efficiency, wide applicability, high construction accuracy, and good completion quality.

[0011] Further, the S100 includes the following steps:

[0012] S110: In the cruise ship stairway area, the public areas across multiple sections or main vertical zones, and the unit cabin areas, taking the two opposite side bulkheads in the ship width direction as a reference, after translating a preset second distance towards the center of the two side bulkheads, the opposite M.K. lines are respectively marked on the decks of the respective areas;

[0013] S120: Taking the opposite M.K. lines for centering and marking the R.C. reference lines.

[0014] In this solution, through the above steps, it can prevent operations such as applying dressings on the two opposite side bulkheads before the R.C. reference lines are marked, making it difficult to measure the actual distance between the two opposite side bulkheads. By pre-marking the M.K. lines based on the two side bulkheads, it can effectively avoid the influence of subsequent operations on the marking of the R.C. reference lines, and at the same time is also conducive to the subsequent verification of the R.C. reference lines.

[0015] Further, the S200 includes the following content:

[0016] S210: In the cruise ship stairway area, taking the bisecting center line of the fire door in the cruise ship stairway area, the R.L. reference line is marked on the deck;

[0017] S220: In the public areas across multiple sections or main vertical zones and the unit cabin areas, measure the spacing between adjacent bulkheads within the area in the ship length direction, compare it with the corresponding spacing before the section leveling to obtain the first spacing deviation dimension, and distribute the first spacing deviation dimension to the adjacent R.L. reference lines within the area;

[0018] S230. Measure the distance between the outer plate and the bulkhead in the breadth direction within the common area across multiple subsections or main vertical zones and within the unit cabin area, compare it with the corresponding distance before the subsection leveling, obtain the second distance deviation dimension, and distribute the second distance deviation dimension to the opposite R.L. reference line within this area.

[0019] In this solution, within the cruise ship stairway area, use the symmetrically arranged fire doors within this area as reference marks for the R.L. reference line. The fixation of the reference object makes the corresponding R.L. reference line relatively fixed. Within the common area across multiple subsections or main vertical zones and within the unit cabin area, by measuring the corresponding dimensions before and after the subsection leveling, obtaining the corresponding dimension deviations, and then distributing these deviations to the adjacent or opposite R.L. reference lines, mark the R.L. reference line in this way, so that the positions of the R.L. reference lines in the same direction are as fixed as possible, and the adjacent distances will not cause excessive deviations.

[0020] Furthermore, the first distance deviation dimension in S220 is evenly distributed to the adjacent R.L. reference lines within this area, and the second distance deviation dimension in S230 is evenly distributed to the opposite R.L. reference lines within this area.

[0021] In this solution, the first distance deviation dimension and the second distance deviation dimension are evenly distributed to the adjacent or opposite R.L. reference lines, making the distribution method more fixed. According to the corresponding distance deviation dimension, the corresponding reference line is relatively fixed.

[0022] Furthermore, in S220, the distance between adjacent R.L. reference lines is compared with the corresponding distance before the subsection leveling to obtain the third distance deviation dimension, and by adjusting the distribution of the first distance deviation dimension, make the third distance deviation dimension less than 10 mm.

[0023] In this solution, in the length direction of the ship, obtain the corresponding R.L. reference line by distributing the first distance deviation dimension, and then compare it with the R.L. reference line before the subsection leveling to obtain the third distance deviation. If this deviation dimension is too large, the first distance deviation dimension can be redistributed to minimize the deviation between the R.L. reference line and the corresponding reference line before the subsection leveling.

[0024] Furthermore, S300 includes the following steps:

[0025] S310. Use a horizontal measuring tool to perform a horizontal measurement on the deck within the measurement area and determine the highest point;

[0026] S320. Based on the highest point, after translating upward by a preset first distance, mark the R.H. contour lines on the periphery of the column and on the surface of the bulkhead.

[0027] In this solution, through the above steps, mark the contour lines relative to the highest point of the deck, so that there is a corresponding reference benchmark in the height direction during subsequent interior fitting-out construction. For example, when the whole ship floats, if the transverse inclination difference of the hull exceeds a certain standard, subsequent operations such as dressing can be carried out based on the deck and the contour lines on the deck.

[0028] Further, in S320, the column includes a rectangular pillar and a circular pillar. Mark the R.H. contour lines on all four peripheral surfaces of the rectangular pillar, and mark the R.H. contour lines at intervals of 120 degrees on the periphery of the circular pillar.

[0029] In this solution, through the above method, when the column includes a rectangular pillar and a circular pillar, mark the R.H. contour lines at corresponding positions respectively, making the marking of the contour lines more comprehensive and obvious.

[0030] Further, in S320, the bulkhead has a notch, and mark the R.H. contour lines on the surface of the bulkhead every 4 meters and 200 millimeters away from the edge of the notch.

[0031] In this solution, through the above method, mark the R.H. contour lines every 4 meters on the bulkhead. In the case of having a notch, mark the R.H. contour lines 200 millimeters away from the edge of the notch, making the marking of the contour lines on the bulkhead more comprehensive and obvious.

[0032] Further, the horizontal measuring tool is any one of a level, a total station or a screed.

[0033] In this solution, it is preferable to select any one of a level, a total station or a screed as the horizontal measuring tool.

[0034] Further, in S300, the non-mechanical area includes an enclosed area and a public area formed by the bulkhead enclosure, and unit cabins bounded by the bulkhead.

[0035] In this solution, the non-mechanical area where the contour lines are marked specifically includes an enclosed area and a public area formed by the bulkhead enclosure, and unit cabins bounded by the bulkhead. The marking range is wide, and the subsequent general assembly construction reference is more comprehensive.

[0036] The positive and progressive effects of the present invention are as follows:

[0037] After the hull construction and outfitting of the cruise ship are completed, it needs to enter the interior fitting-out stage. The areas involved in the interior fitting-out stage include the cruise ship stairway area, the public areas spanning multiple sections or main vertical zones, and the unit cabin areas. In each of the above-mentioned areas, the distance between the two side bulkheads is measured separately in the ship width direction, and the midpoint of this distance is determined. The R.C. reference lines are marked separately on the decks of the respective areas. Using the bulkheads and side bulkheads within the area as a reference in the ship length direction or ship width direction, the R.L. reference lines are marked separately on the decks of the respective areas. Taking the highest point of the deck in the non-mechanical area of the cruise ship as a reference, after translating upward by a certain distance, the R.H. contour lines are marked on the columns or side bulkheads. By marking the corresponding reference lines in the length, width, and height directions in the above-mentioned areas, each subcontractor can construct relatively independently according to the reference lines during the interior fitting-out stage, without interference problems among each other, ensuring the smooth progress of the interior fitting-out project. This method is simple to operate, has relatively high safety and efficiency, wide applicability, high construction accuracy, and good completion quality. Brief Description of the Drawings

[0044] The embodiments of the present invention will be described in detail below. The examples of the embodiments are shown in the drawings, where the same or similar reference numerals represent the same or similar elements or elements with the same or similar functions from beginning to end. The embodiments described below with reference to the drawings are exemplary and are intended to explain the present invention, and should not be construed as limiting the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0045] In the description of the present invention, it should be understood that the orientation or positional relationship indicated by the terms "center", "longitudinal", "transverse", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "circumferential", "radial", etc. is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation to the present invention.

[0046] In addition, the terms "first" and "second" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more of such features. In the description of the present invention, the meaning of "a plurality" is two or more unless otherwise specifically defined.

[0047] The construction stage of a large cruise ship is divided into the hull stage (the hull stage is divided into the block stage, the sub-assembly stage, and the outfitting stage), the outfitting stage, and the interior fitting stage. The interior fitting of the cruise ship is mainly subcontracted. Different from traditional procurement, it relies on subcontractors to conduct the whole process management from conceptual design, basic design, materials, construction to final delivery. The construction of each subcontractor is relatively independent, and there are interference problems during the interior fitting construction process, including the interference of the structure on the interior fitting, the interference of the outfitting on the interior fitting, and the construction interference between subcontractors. Therefore, there is an urgent need to unify the benchmark construction method for the interior fitting of cruise ships. At present, only in the hull stage, the R.C. reference line and the R.L. reference line are automatically marked on the main board splicing, and the sub-assembly needs to be leveled in the subsequent manufacturing stage. During the leveling process, shrinkage will occur at the leveling position. In some places with a large shrinkage amount, the originally marked R.C. reference line and R.L. reference line may shift and cannot be used in the subsequent interior fitting stage. Therefore, this embodiment provides a construction method for the reference line of the interior fitting of cruise ships.

[0048] Before introducing the construction method for the reference line of the interior fitting of cruise ships, each reference line will be introduced first. The R.L. reference line serves as the construction reference for the unified length and width directions of the interior fitting project and the reference line for connecting the outfitting parts of the interior fitting. The R.C. reference line serves as the construction reference line for the unified hull center line of the interior fitting. The R.H. contour line is the reference line for the unified plane after offsetting a preset distance upward from the highest point of the deck level. The M.K line is the marked line after translating a preset distance based on a specific reference benchmark.

[0049] As Figure 1As shown, the construction method of the interior reference line of the cruise ship mainly includes the following contents: S100. In the stairway area of the cruise ship, in the public area spanning multiple total sections or main vertical zones, and in the unit cabin area, take the midpoint of the distance between the two side bulkheads in the ship width direction, and mark the R.C. reference line on the deck within the area. S200. In the stairway area of the cruise ship, in the public area spanning multiple total sections or main vertical zones, and in the unit cabin area, take the bulkhead or side bulkhead within the area as the reference in the ship length direction and the ship width direction respectively, and mark the R.L. reference line on the deck within the area. S300. Take the highest point of the deck in the non-mechanical area of the cruise ship as the reference, and mark the R.H. contour line on the column or bulkhead after translating upward by a preset first distance.

[0050] As Figure 2 and Figure 3 shown, in the stairway area of the cruise ship, in the public area spanning multiple total sections or main vertical zones, and in the unit cabin area, measure the actual distance between the two side bulkheads in the ship width direction within the area, and take the midpoint of this distance, that is, mark the R.C. reference line at the middle position between the two side bulkheads. Similarly, the R.C. reference line can also be marked in the unit cabin area in the same way. Further, the operation of marking the R.C. reference line in S100 can be specifically divided into two steps: S110. In the stairway area of the cruise ship, in the public area spanning multiple total sections or main vertical zones, and in the unit cabin area, take the two opposite side bulkheads in the ship width direction as the reference, and after translating a preset second distance towards the center of the two side bulkheads, mark the opposite M.K. lines on the deck within the area respectively. S120. Take the midpoint of the opposite M.K. lines to mark the R.C. reference line. For example, first, in each area, take the two side bulkheads as the reference in the ship width direction, and mark two parallel M.K. lines 100 mm away from the two side bulkheads. Then, when marking the R.C. reference line, the midpoint can be taken with reference to the above two M.K. lines, without referring to the two side bulkheads anymore. By this method, it can prevent the actual distance between the two opposite side bulkheads from being difficult to measure due to dressing and other process operations on the two opposite side bulkheads before the R.C. reference line is marked. By pre-marking the M.K. lines according to the two side bulkheads, it can effectively avoid the influence of subsequent operations on the marking of the R.C. reference line, and is also conducive to the subsequent verification of the R.C. reference line.

[0051] As Figure 2 shown, in S200, in the stairway area of the cruise ship, mark the R.L. reference line on the deck with the bisecting center line of the fire door in this area. Since symmetrical fire doors will be set in the stairway area of the cruise ship, the center line of the symmetrical fire doors can be selected as the R.L. reference line in the ship length direction of this area. With a fixed reference object, the corresponding R.L. reference line is also relatively fixed.

[0052] As Figure 3 shown, in S200, within the common area spanning multiple overall sections or main vertical zones, measure the spacing between adjacent bulkheads in the longitudinal direction of the ship within the area, compare it with the corresponding spacing before the overall section leveling to obtain the first spacing deviation dimension, and distribute the first spacing deviation dimension to the adjacent R.L. reference lines within the area; measure the spacing between the outer plate and the bulkhead in the transverse direction of the ship, compare it with the corresponding spacing before the overall section leveling to obtain the second spacing deviation dimension, and distribute the second spacing deviation dimension to the opposite R.L. reference lines within the area.

[0053] Specifically, there are many bulkheads within the common area spanning multiple overall sections or main vertical zones. Therefore, the bulkheads before and after the overall section leveling can be used as measurement reference points to mark the R.L. reference lines. In the longitudinal direction of the ship, the spacing between adjacent bulkheads can be measured and then compared with the corresponding spacing of the adjacent bulkheads before the overall section leveling to obtain the difference between the two as the first spacing deviation dimension, and then distribute the first spacing deviation dimension between the adjacent R.L. reference lines. Since during the hull manufacturing stage, the corresponding R.L. reference lines are pre-marked on each section, but due to the offset caused by subsequent processes such as overall section leveling, they cannot be used. At this time, the R.L. reference lines marked during the hull manufacturing stage can be used as a reference. For example, when the first spacing deviation is 12 mm, the previous adjacent R.L. reference lines can be moved. If one R.L. reference line is moved 7 mm, the other adjacent reference line is moved 5 mm, or both R.L. reference lines are moved 6 mm. Of course, in other embodiments, it is also possible not to use the previous R.L. reference lines as a reference and directly mark the R.L. reference lines directly with the adjacent bulkheads as the reference, but it may be relatively troublesome in terms of procedures.

[0054] In the transverse direction of the ship, similarly, the spacing between the outer plate and the bulkhead can be measured, compared with the corresponding spacing before the overall section leveling to obtain the second spacing deviation dimension, and distribute the second spacing deviation dimension to the opposite R.L. reference lines within the area. Therefore, in the transverse direction of the ship, the R.L. reference lines are generally symmetrically distributed centered on the R.C. reference line. Therefore, when distributing the second spacing deviation dimension, it is distributed to the symmetric R.L. reference lines so that the newly marked R.C. reference line can also be symmetrically distributed. The positions of the R.L. reference lines marked in the above manner are as fixed as possible among each other, and the adjacent distances will not cause excessive deviation. Similarly, within the unit cabin area, the R.L. reference lines can also be marked in the same way.

[0055] Furthermore, the first spacing deviation dimension can be evenly distributed to adjacent R.L. reference lines within this area, and the second spacing deviation dimension is evenly distributed to opposite R.L. reference lines within this area, making the distribution method more fixed. According to the corresponding distance deviation dimension, the corresponding reference lines are relatively fixed. However, if the distance between adjacent R.L. reference lines is too large after the even distribution, the first spacing deviation dimension can be appropriately adjusted so that the third spacing deviation dimension is less than 10 mm, that is, the third spacing deviation dimension is obtained by comparing the spacing between adjacent R.L. reference lines with the corresponding spacing before the overall straightening of the section, and by adjusting the distribution of the first spacing deviation dimension, so that the third spacing deviation dimension is less than 10 mm. If the first spacing deviation is 12 mm, the distances distributed on both sides can be adjusted as needed, as long as the sum of the distances distributed on both sides is equal to 12 mm.

[0056] As Figure 4 shown, S300 includes the following steps: S310, using a horizontal measuring tool to perform a horizontal measurement on the deck within the measurement area and determine the highest point; S320, based on the highest point, after translating upward by a preset first distance, mark R.H. contour lines on the periphery of the column and on the surface of the bulkhead.

[0057] Specifically, the non-mechanical area in S300 includes an enclosed area and a public area formed by the bulkhead enclosing, as well as unit cabins bounded by the bulkhead. Within the above areas, any one of a level, a total station, or a rotary laser level can be used to perform a horizontal measurement on the deck within the measurement area and determine the highest point. Based on this highest point, after translating upward by a preset first distance, mark R.H. contour lines on the periphery of the column and on the surface of the bulkhead. Among them, the column includes a rectangular pillar and a circular pillar. R.H. contour lines are marked on all four peripheral surfaces of the rectangular pillar, and R.H. contour lines are marked at intervals of 120 degrees on the periphery of the circular pillar. Referring to Figure 5 shown, R.H. contour lines are marked on the surface of the bulkhead at intervals of 4 meters. If there is a notch on the bulkhead, R.H. contour lines are marked 200 millimeters away from the edge of the notch. By respectively marking R.H. contour lines at corresponding positions, the marking of the contour lines is more comprehensive and obvious.

[0058] As Figure 6 shown, contour lines are marked relative to the highest point of the deck, so that there is a corresponding reference benchmark in the height direction during subsequent interior fitting-out construction. For example, when the entire ship floats, if the transverse inclination difference of the hull exceeds a certain standard, subsequent operations such as dressing can be carried out based on the deck and the contour lines on the deck, preventing the uneven thickness of the dressing caused by using the horizontal plane as the reference point.

[0059] In summary, after the hull construction and outfitting of the cruise ship are completed, it needs to enter the interior fitting-out stage. The areas involved in the interior fitting-out stage include the cruise ship stairway area, the public areas spanning multiple sub-assemblies or main vertical zones, and the unit cabin areas. In each of the above-mentioned areas, the distance between the two side bulkheads is measured separately in the ship width direction, and the midpoint of this distance is determined. The R.C. reference lines are marked respectively on the decks of the corresponding areas. Taking the bulkheads and sheathing within the area as the reference, the R.L. reference lines are marked respectively on the decks of the corresponding areas in the ship length direction or ship width direction. Taking the highest point of the deck in the non-mechanical area of the cruise ship as the reference, after translating upward by a certain distance, the R.H. contour lines are marked on the columns or bulkheads. By marking the corresponding reference lines in the length, width, and height directions in the above-mentioned areas, each subcontractor can construct relatively independently according to the reference lines during the interior fitting-out stage, without interference with each other, ensuring the smooth progress of the interior fitting-out project. This method is simple to operate, has relatively high safety and efficiency, wide applicability, high construction accuracy, and good completion quality.
