Description

Technical Field

[0001] The invention relates to the field of transverse bulkhead manufacturing, in particular to a method for constructing a transverse bulkhead with a guide rail frame. Background Art

[0002] Bulkheads are used to divide the interior of a ship into several cargo holds. In order to position and fix containers, rails are installed on the bulkheads of container ships so that when loading containers, they can be loaded into the cargo holds along the rails on the bulkheads. Therefore, during the construction of container ships, rails need to be installed on the bulkheads. The rails can be installed directly on the bulkhead section after it is built. The rails can also be installed on the bulkhead sections first, and then the bulkhead sections with rails are assembled into bulkhead sections. When the rails are installed in the latter way, the bulkhead sections need to be placed horizontally, and then a rail horizontal plane is selected from the rails on the bulkhead sections as the reference horizontal plane, and then the port side bulkhead section and the starboard side bulkhead section are adjusted to the same horizontal plane with reference to the reference horizontal plane. Since the guide rail frame is long and easily deformed, if the guide rail frame used as the reference horizontal plane is deformed, the port section of the bulkhead and the starboard section of the bulkhead cannot be aligned on the same horizontal plane, and the horizontality of the guide rail frame needs to be adjusted again to align the port section of the bulkhead and the starboard section of the bulkhead, which will delay the assembly progress of the port section of the bulkhead and the starboard section of the bulkhead. In the process of first installing the guide rail frame on the bulkhead section and then assembling the bulkhead sections with the guide rail frame into the bulkhead assembly section, the prior art cannot provide a stable reference horizontal plane to align the port section of the bulkhead and the starboard section of the bulkhead.

Once the first reference lines and the second reference lines are set, their positions can be kept stable. In this way, the first reference plane formed by at least two first reference lines can maintain a stable positional relationship with respect to the port side section of the diaphragm tank, and the second reference plane formed by at least two second reference lines can also maintain a stable positional relationship with respect to the starboard side section of the diaphragm tank. Since the first reference plane and the second reference plane can maintain a stable positional relationship with respect to the port side section or the starboard side section of the diaphragm tank, when adjusting the starboard side section of the diaphragm tank with the first reference plane as the measurement reference, the coplanarity of the second reference plane and the first reference plane can be made more accurate. Since the first reference plane is parallel to the port side section of the diaphragm tank and the second reference plane is parallel to the starboard side section of the diaphragm tank, after the first reference plane and the second reference plane are more accurately coplanar, the alignment accuracy of the port side section and the starboard side section of the diaphragm tank is also higher. At the same time, since there is no need to adjust the levelness of the guide rail frame to align the port side section and the starboard side section of the diaphragm tank, the overall assembly progress of the port side section and the starboard side section of the diaphragm tank is accelerated.

[0115] It should be noted that the terms "first", "second", etc. in the specification and claims of the present invention and the above-mentioned drawings are used to distinguish similar objects, and do not necessarily need to describe a specific order or sequence. In addition, the terms "comprising" and "having" and any variations thereof are intended to cover non-exclusive inclusion.

[0116] Please refer to Figures 1-8 , in one embodiment, it is a construction method of a transverse bulkhead with a guide frame, including the following steps:

[0117] M1: Fabricate the starboard diaphragm section 10 and the port diaphragm section 11. M2: Set at least two first reference lines on the starboard diaphragm section 10. Among them, at least two first reference lines form a first reference plane 10A, and the first reference plane 10A is parallel to the wall surface of the starboard diaphragm section 10. Set at least two second reference lines on the port diaphragm section 11. Among them, at least two second reference lines form a second reference plane 11A, and the second reference plane 11A is parallel to the wall surface of the port diaphragm section 11. Please refer to Figure 6 and Figure 7 , mark the port installation auxiliary lines on the starboard diaphragm section 10. The port installation auxiliary lines include the hull center line 10b, the first profile line 10c, the first guide rail frame edge line 10d, and the first connecting plate edge line 10e. For example, the first profile line 10c can be a 10m profile line marked by measuring 10.005m from the hull center line 10b to the starboard (m is the unit of meter, the same below). Taking the first profile line 10c as the starting point, draw the first guide rail frame edge lines 10d from left 1 to left 8 on both sides of it. Take the center line of the first guide rail 12 offset by 165mm (mm is the unit of millimeter, the same below) as the first connecting plate edge line 10e. Please refer to Figure 6 and Figure 8 , mark the starboard installation auxiliary lines on the port diaphragm section 11. The starboard installation auxiliary lines include the second profile line 11b, the third profile line 11c, the second guide rail frame edge line 11d, and the second connecting plate edge line 11e. For example, the second profile line 11b can be a 1470mm profile line, and the third profile line 11c can be a 10m profile line made by measuring 8.535m from the 1.47m line from the midship to the starboard. Taking the third profile line 11c as the starting point, draw the second guide rail frame edge lines 11d from right 1 to right 8 on both sides of it. Take the center line of the second guide rail 13 offset by 165mm as the second connecting plate edge line 11e. M3: Install the first guide rail 12 on the starboard diaphragm section 10 according to the port installation auxiliary lines. Install the second guide rail 13 on the port diaphragm section 11 according to the starboard installation auxiliary lines. M4: Adjust the port diaphragm section 11 with the first reference plane 10A as the measurement reference so that the second reference plane 11A and the first reference plane 10A are coplanar. The coplanarity deviation between the first reference plane 10A and the second reference plane 11A can be ≤10mm. M5: Combine the starboard diaphragm section 10 and the port diaphragm section 11 to form the diaphragm subassembly.

[0118] Since the starboard side section 10 and the port side section 11 of the diaphragm tank are not easily deformed by themselves, at least two first reference lines and at least two second reference lines are respectively provided on the starboard side section 10 and the port side section 11 of the diaphragm tank. Once the first reference lines and the second reference lines are set, their positions can be kept stable. In this way, the first reference plane 10A formed by at least two first reference lines can maintain a stable positional relationship with respect to the starboard side section 10 of the diaphragm tank, and the second reference plane 11A formed by at least two second reference lines can also maintain a stable positional relationship with respect to the port side section 11 of the diaphragm tank. Since the first reference plane 10A and the second reference plane 11A can maintain stable positional relationships with respect to the starboard side section 10 or the port side section 11 of the diaphragm tank, when adjusting the port side section 11 of the diaphragm tank with the first reference plane 10A as the measurement reference, the coplanarity of the second reference plane 11A and the first reference plane 10A can be made more accurate. Since the first reference plane 10A is parallel to the starboard side section 10 of the diaphragm tank and the second reference plane 11A is parallel to the port side section 11 of the diaphragm tank, after the first reference plane 10A and the second reference plane 11A are more accurately coplanar, the alignment accuracy between the starboard side section 10 and the port side section 11 of the diaphragm tank is also higher. At the same time, since it is not necessary to adjust the levelness of the guide rail frame to align the starboard side section 10 and the port side section 11 of the diaphragm tank, the overall assembly progress of the starboard side section 10 and the port side section 11 of the diaphragm tank is accelerated.

[0119] Please also refer to Figures 2-4 Preferably, at least two first reference lines are provided on the starboard side section 10 of the diaphragm tank. Among them, the steps for at least two first reference lines to form a first reference plane 10A parallel to the wall surface of the starboard side section 10 of the diaphragm tank include: setting at least 4 first reference rods 14 on the starboard side section 10 of the diaphragm tank, and setting at least one first reference point 10a on each first reference rod 14. Among them, the first reference point 10a should be higher than the first guide rail surface 120. At least one first reference line passes through at least two first reference points 10a, and at least another first reference line passes through at least another two first reference points 10a. The heights of the first reference points 10a on the first reference rods 14 are all the same, that is, the two first reference lines are parallel or intersect to form the first reference plane 10A. The first guide rail frame 12 can be a guide rail frame with an L-shaped cross section, and the first guide rail surface 120 can be a guide rail surface parallel to the wall surface of the starboard side section of the diaphragm tank. For example, the first reference rod 14 can be a 3# angle iron with a specification of L30×30×4×700mm, and the first reference point 10a can be a center punch set on the first reference rod 14. By setting the first reference point 10a on the first reference rod 14 and making the first reference point 10a higher than the first guide rail surface 120, the first reference point 10a can be prevented from being blocked by the first guide rail surface 120, which is convenient for subsequent wire pulling at different first reference points 10a to form the first reference line.

[0120] Please also refer to Figure 2 、 Figure 3 and Figure 5 , preferably, the steps of setting at least two second reference lines on the starboard section 11 of the transverse bulkhead, wherein at least two second reference lines form a second reference plane 11A parallel to the wall surface of the starboard section 11 of the transverse bulkhead include: setting at least 4 second reference rods 15 on the starboard section 11 of the transverse bulkhead, and setting at least one second reference point 11a on each second reference rod 15, wherein the second reference point 11a is higher than the second guide rail surface 130. At least one second reference line passes through at least two second reference points 11a, and at least another second reference line passes through at least two other second reference points 11a. The heights of the second reference points 11a on the second reference rods 15 are the same, that is, the two second reference lines are parallel or intersect to form the second reference plane 11A. The second guide rail frame 13 can be a guide rail frame with an L-shaped cross section, and the second guide rail surface 130 can be a guide rail surface parallel to the wall surface of the starboard section of the transverse bulkhead. For example, the second reference rod 15 can be a 3# angle iron with a specification of L30×30×4×700mm, and the second reference point 11a can be a center punch set on the second reference rod 15. By setting the second reference point 11a on the second reference rod 15 and making the second reference point 11a higher than the second guide rail surface 130, the second reference point 11a can be prevented from being blocked by the second guide rail surface 130, which is convenient for subsequent wire pulling at different second reference points 11a to form the second reference line.

[0121] Please also refer to Figure 7 、 Figure 9 and Figure 10 , preferably, the steps of installing the first guide rail frame 12 on the port section 10 of the transverse bulkhead according to the port installation auxiliary line include:

[0122] M61: Install the first connecting plate 16 with reference to the first connecting plate edge line 10e. For example, the first connecting plate 16 can be welded to the port section 10 of the transverse bulkhead. M62: Lift and install the first guide rail frame 12 to the first connecting plate 16 with reference to the first guide rail frame edge line 10d. For example, the first guide rail frames 12 numbered 1# - 8# can be lifted and installed to the first connecting plate 16 according to the numbers from left 1 to left 8 of the first guide rail frame edge line 10d. M63: Position the first guide rail frame 12. M64: Detect the straightness of the first guide rail frame 12. M65: Fix the first guide rail frame 12 to the first connecting plate 16. For example, the first guide rail frame 12 can be fixed to the first connecting plate 16 by welding.

[0123] As Figure 11 shown, preferably, step M63 includes:

[0124] M631: Position the first guide rail rack 12 left and right according to the first guide rail rack edge line 10d. For example, the first guide rail rack 12 can be positioned left and right with a distance gauge as the standard. M632: Position the first guide rail rack 12 below the first hatch coaming up and down. Among them, the inspection line made by measuring 550 mm downward from the upper edge of the first hatch coaming panel 100 is used as the positioning basis for the guide head edge of the first guide rail rack 12. The non - coincidence degree between all the first guide rail racks 12 and the hull members should be less than or equal to 1 / 3 of the plate thickness. M633: Position the first guide rail rack 12 high and low.

[0125] Please also refer to Figures 12-15 , preferably, step M632 includes:

[0126] S11: Set the third benchmarks 17 at the side positions of two adjacent first guide rail racks 12 on the same first connecting plate 16 respectively, and set the first marks 170 on the third benchmarks 17. For example, the third benchmark 17 can be a 3# angle iron with a specification of: L30×30×4×2600 mm. The first mark 170 can be a mark formed on the third benchmark 17 by a stone pen or laser. The height of the first mark 170 is between 320 - 700 mm upward from the theoretical wall surface of the transverse bulkhead starboard section 10. The third benchmark 17 can be perpendicular to the wall surface of the transverse bulkhead starboard section 10, and the length of both ends extending out of the first hatch coaming panel 100 is 400 mm.

[0139] S21: At the positions beside two adjacent second guide frames 13 on the same second connecting plate 19, fourth benchmarks 20 are respectively arranged, and second markings 200 are arranged on the fourth benchmarks 20. For example, the fourth benchmark 20 can be an angle iron No. 3 with a specification of L30×30×4×2600mm, and the second marking 200 can be a mark formed on the fourth benchmark 20 by a stone pen or laser. The height of the second marking 200 is between 320 - 700mm upward from the theoretical surface of the wall of the starboard transverse bulkhead section 11. The total number of the first benchmark 14, the second benchmark 15, the third benchmark 17 and the fourth benchmark 20 is N + 6, where N is the total number of the first connecting plate 16 and the second connecting plate 19.

[0142] S24: Straighten the second thin line 21 and connect it to the fourth benchmark 20 respectively, so that the second thin line 21 is respectively connected to a second marking 200. Among them, the distance from the second thin line 21 to the upper edge of the second hatch coaming panel 110 is consistent with the distance B2. Taking the distance from the second thin line 21 to the second guide surface 130 as A2, then A2 = B2 - 150mm. When there are multiple fourth benchmarks 20, such as 3, two second thin lines 21 can be prepared, and each second thin line 21 is connected to a second marking 200. Measure the distance A2 from the two second thin lines 21 to the second guide surface 130 respectively in two times, and then take the average value.

M82: Re-inspect and adjust the hull center line 10b and the first profile line 10c until they are correct. After the installation of the first guide frames 12 is completed, the hull center line 10b and the first profile line 10c may be deformed. Therefore, they can be restored to the correct state (such as the design state) through re-inspection and adjustment. For example, the hull center line 10b and the first profile line 10c can be re-inspected until they are correct by using a theodolite and an angle gauge. M83: Re-inspect and adjust the perpendicularity of the second hatch coaming panel 110, the second profile line 11b, and the third profile line 11c until they are correct. After the installation of the second guide frames 13 is completed, the perpendicularity of the second hatch coaming panel 110, the second profile line 11b, and the third profile line 11c may be deformed. Therefore, they can be restored to the correct state (such as the design state) through re-inspection and adjustment. For example, the perpendicularity of the second hatch coaming panel 110, the second profile line 11b, and the third profile line 11c can be re-inspected until they are correct by using a theodolite and an angle gauge. M84: Adjust the half-width position of the starboard transverse bulkhead section 11 by adjusting the spacing between the second guide frames 13 adjacent to the large joint.
