Description

Technical Field

[0001] The present invention relates to the technical field of cruise ship modular construction, and more specifically, to a method for prefabricating a cruise ship modular cabin. Background Art

[0002] One of the most prominent difficulties in the construction of large luxury cruise ships is the huge number of cabins. Currently, large cruise ships have more than 1,000 cabins, and the largest Oasis of the Seas class has 2,700 cabins. Large cruise ships need to complete the construction and delivery of such a large number of cabins in a short period of time. If they still follow the traditional practice of "installation in sequence of time and process", the delivery date will not be guaranteed. The emergence of the concept of prefabricated modular cabins and its practice provide an effective way and method to solve this problem. In addition, prefabricated modular cabins can also reduce the number of construction personnel, reduce the difficulty of construction, reduce the risk of material stacking on board, and improve the quality of construction.

[0003] The main design and construction contents of the modular cabin construction plan include: cabin independent frame design, cabin cable, ventilation duct layout and reserved interface design, manufacturing of parts and furniture, factory prefabrication of cabins, welding of embedded parts on board, installation on board, etc. Among them, the construction process and method of factory prefabrication of cabins are very important to improve the construction efficiency of modular cabins, and the reinforcement method of each component of prefabricated cabins is very critical to the reliability of modular cabin hoisting and on-board installation. At present, the modular cabin prefabrication method rarely involves the research on construction process and component reinforcement to improve the efficiency and quality of prefabrication. Therefore, developing an efficient and reliable cruise ship modular cabin prefabrication method is a technical problem that needs to be solved urgently. Summary of the invention

[0004] In view of the above-mentioned defects of the prior art, the present invention provides a method for prefabrication of modular cabins of cruise ships, which satisfies the structural reliability of efficient prefabrication of modular cabins of cruise ships and actual ship installation through optimized design of construction procedures and component reinforcements.

[0005] To achieve the above object, the present invention provides a method for prefabricating a modular cabin of a cruise ship, which is characterized by comprising the following steps:

[0008] Step S3, connecting the bottom square tubes serving as the cabin foundation on the prefabricated platform in order starting from the wet area unit; installing the first side connector of the bottom square tube;

[0009] Step S4, installing the wall panel units on the bottom square tube in the order starting from the wet area unit, and then installing the wall panel reinforcement pieces at the connection between the wall panel unit and the wet area unit and at the connection between the corner wall panel units;

[0010] Step S5, installing temporary reinforcement supports for the cabin door and the bottom square tube;

[0011] Step S6, sequentially installing the second side connector on the top, the ceiling, and the ceiling reinforcement angle plate; the electrical construction is carried out simultaneously with the ceiling construction;

[0012] Step S7, installing furniture;

[0013] Step S8: Install top equipment and pipelines, and reinforce pipelines and cabin doors.

[0014] Furthermore, before step S2, a heat insulating material is filled into the bottom square tube.

[0015] Furthermore, in step S3, the bottom square tube and the first side connector are fixed in sequence with an L-shaped inner sleeve and a first screw, and are connected to the square tube of the wet area unit base; the spacing between the bottom square tube and the first side connector connected by the first screw is 300~500mm; the first side connector serves as a wall panel connector, which is an asymmetric U-shaped connecting profile connected to the upper surface of the bottom square tube; the position is adjusted during the installation process to ensure that the outer dimensions and angles of the cabin foundation meet the requirements of the drawings and the diagonals are equal; after the adjustment is completed, the bottom square tube is fixed to the prefabricated platform with square tube fixing plates and glue on both sides of the corners of the cabin foundation.

[0016] Furthermore, in step S4, the wall panel unit connected to the wet area unit is used as the starting wall panel unit, and the U-shaped edging profile used to fix the wet area unit and the starting wall panel unit is tested by a spirit level to ensure that the wall panel units are vertically connected; a groove is cut at the bottom of the wall panel unit, and the groove matches the groove type of the first side connector; the starting wall panel unit is connected to the standard wall panel unit, and a C-type male snap-in seat and a C-type female snap-in block are respectively provided on both sides of the standard wall panel unit; the wall panel unit is inserted from the starting point, and during insertion, a spirit level is used to check whether the wall panel unit is inserted in place and is horizontal and vertical; the wall panel reinforcement is an edge sealing profile connecting the wall panels on both sides.

[0017] Furthermore, in step S4, the bottom groove of the wall panel unit is butt-jointed with the first side connector at an angle of 45°; before installing the bottom groove, a layer of sealant is evenly applied on the surface of the first side connector; the bottom groove is placed on the bottom square tube, and the butt joint gap is controlled within 1 mm; after adjustment, the bottom groove of the wall panel unit is fixed to the bottom square tube with self-tapping screws; the spacing between the self-tapping screws is 300~500mm; the starting point and end point of each bottom groove are fixed with screws, and the screw spacing is 20mm.

[0018] Furthermore, in step S5, the temporary reinforcement support includes a transverse support, a longitudinal support and an oblique support; the longitudinal support is connected to the bottom square tube in the middle of the foundation; the transverse support is connected to the longitudinal support in a T-shape, and the oblique support is arranged at the corner of the bottom square tube.

[0019] Further, in step S6, the second side connector serves as a ceiling connector, including an L-shaped connecting profile and a flanged U-shaped connecting profile, wherein the L-shaped connecting profile is set on the wet area unit and the side of the cabin door by a second screw, and the flanged U-shaped connecting profile is set in other areas by a second screw.

[0020] Furthermore, in step S6, the ceiling is first installed using a suction cup and a rubber hammer according to the plan and the numbers on the ceiling. After all the ceilings are installed, a circle of tape is wrapped along the gap between the ceiling and the top groove, and then the second side connector is connected to the ceiling groove corner with screws.

[0021] Furthermore, in step S6, after the ceiling is installed, ceiling reinforcement angle plates are installed at the corners around the ceiling, fixed with self-tapping screws, and transverse reinforcement beams are installed on the ceiling through the reinforcement plates.

[0054] Example

[0055] See also Figure 1 This embodiment provides a method for prefabricating a modular cabin of a cruise ship, comprising the following steps:

[0056] Step S1, marking and positioning of the cabin prefabricated platform. Preferably, in this step, the insulation material (such as insulation cotton) is pre-filled into the bottom square tube 1.

[0057] Step S2: assembling the bottom square tube 1 and the wet area unit 2 together on the prefabricated platform.

[0058] Step S3, see Figures 2 to 7 On the prefabricated platform, connect the bottom square tube 1 as the cabin foundation in order starting from the wet area unit 2; install the first side connecting piece 11 of the bottom square tube 1.

[0059] More specifically, see Figures 2 to 6 First, mark and locate the cabin prefabricated platform, and place the wet area unit at the designated location, then press Figure 2 Fix the bottom square tube 1 and the connector with screws and connect them to the square tube of the base of the wet zone unit 2. For further information, see Figure 5 , use the L-shaped inner sleeve 13 and the first screw 14 to fix the bottom square tube 1 and the first side connector 11 in sequence, and connect them to the square tube of the wet area unit base. The spacing between the first screw 14 connecting the bottom square tube 1 and the first side connector 11 is 300~500mm. The first side connector 11 is used as a wall panel connector and is an asymmetric U-shaped connecting profile connected to the upper surface of the bottom square tube 1. During the installation process, the position is adjusted to ensure that the outer dimensions and angles of the cabin foundation meet the requirements of the drawings and the diagonals are equal. See Figure 7 After the adjustment is completed, the bottom square tube 1 is fixed to the prefabricated platform with square tube fixing pieces 15 and glue on both sides of the corners of the cabin foundation.

[0060] Step S4, see Figures 8 to 12 , install the wall panel unit 3 on the bottom square tube 1 in the order starting from the wet area unit 2, and then install the wall panel reinforcement 31 at the connection between the wall panel unit 3 and the wet area unit 2 and the corner wall panel unit. The opening and installation of the window bucket on the wall panel will be carried out on board after the cabin is put on board. The height difference of the wall panel installation shall not exceed 0.5mm.

[0061] More specifically, see Figures 8 to 11 In step S4, the wall panel unit connected to the wet area unit is used as the starting wall panel unit 32. The U-shaped edging profile used to fix the wet area unit and the starting wall panel unit is tested by a horizontal ruler to ensure that the wall panel units are vertically connected; a groove is cut at the bottom of the wall panel unit 3, and the groove matches the groove of the first side connector 11; the starting wall panel unit 32 is connected to the standard wall panel unit 33, and the two sides of the standard wall panel unit 33 are respectively provided with a C-type male snap-in seat and a C-type female snap-in block; the wall panel unit is inserted from the starting point. When inserting, use a horizontal ruler to check whether the wall panel unit is inserted in place and is horizontal and vertical. During the installation process, check the verticality of the wall panels and the board seams. The verticality error should be less than 1mm, and the gap between each board should be uniform. See Fig.12 , the wall panel reinforcement 31 is an edge-sealing profile connecting the wall panels on both sides. Furthermore, the bottom groove of the wall panel unit 3 is butted with the first side connector 11 at a 45° angle; before installing the bottom groove, evenly apply a layer of sealant on the surface of the first side connector 11; place the bottom groove on the bottom square tube 1, and control the butt gap within 1 mm; after adjustment, fix the bottom groove of the wall panel unit 3 on the bottom square tube 1 with self-tapping screws; the spacing between the self-tapping screws is 300~500mm; the starting point and end point of each bottom groove are fixed with screws, and the screw spacing is 20mm.

[0062] Step S5: Install the temporary reinforcement support 5 of the cabin door 4 and the bottom square tube 1. Fig.13 After the wall panel construction is completed, check the size of the cabin door opening to ensure that the door opening size meets the size requirements and the diagonals are equal. When installing the cabin door, first place the door in the reserved position of the base, then draw the horizontal and vertical lines, and then adjust the door according to the reference line so that it is parallel to the wall and perpendicular to the ground. After adjustment, fix it to the wall panel with screws according to the screw holes reserved on the side of the door frame. After installation, check whether the door can be opened and closed freely, ensure that the door frame is tightly and seamlessly connected to the wall panel, the door frame is horizontal and vertical, the door opening size is intact, the diagonals are equal, the fixing screws are tightened, the fixing spacing is consistent, and the door leaf opens and closes freely. See Fig.14, a temporary reinforcement support is added to the bottom square tube 1 to prevent the cabin from deforming during lifting. Preferably, the temporary reinforcement support 5 includes a transverse support 51, a longitudinal support 52 and an oblique support 53; the longitudinal support 52 is connected to the bottom square tube 1 in the middle of the foundation; the transverse support 51 is connected to the longitudinal support 52 in a T-shape, and the oblique support 53 is arranged at the corner of the bottom square tube 1.

[0063] Step S6: sequentially install the second side connector 12, the ceiling 7 and the ceiling reinforcement angle plate 72; the electrical construction is carried out while the ceiling 7 is being constructed. Figures 15 to 17 In step S6, the second side connector 12 is used as a ceiling connector, including an L-shaped connector profile 121 and a flanged U-shaped connector profile 122, wherein the L-shaped connector profile 121 is provided on the side of the wet area unit 2 and the cabin door 4 by means of a second screw 123, and the flanged U-shaped connector profile 122 is provided on other areas by means of a second screw 123. Fig.18 and Fig.19 , according to the ceiling layout, start the installation from the longitudinal side board, insert 25mm thick limit wood strips between the ceiling units, and fix the ceiling and the second side connectors one by one with screws. When installing the ceiling, first use a suction cup and a rubber hammer to install the ceiling 7 according to the plan and the number on the ceiling. After all the ceilings 7 are installed, wrap a circle of tape 71 along the gap between the ceiling and the top groove, and then use screws to connect the second side connector 12 to the ceiling groove corner. Ensure that the position and opening direction of the inspection port are correct, and the installation gap between the plate units is uniform and stable.

[0064] Further, see Fig. 20 and Fig.21 After the ceiling is installed, the ceiling reinforcement angle plates 72 are installed at the corners around the ceiling, fixed with self-tapping screws, and the transverse reinforcement beams 73 are installed on the ceiling through the reinforcement plates 74.

[0065] Step S7, installing furniture. More specifically, the furniture is assembled in the furniture assembly area in advance, and then the assembled furniture is transported to the cabin unit, and installed and fixed as required, and finally the switches and sockets are installed. The electrical socket openings on the wall panels should be sealed with sound insulation cotton.

[0066] Step S8: Install the top equipment and pipelines, and reinforce the main components. Fig. 22 The top equipment includes fans 8, insulation boxes 9, lamps, speakers, and smoke detectors. The assembled insulation boxes are fixed to the corresponding equipment with aluminum foil tape. The gas pipelines and cabin doors need to be reinforced, see Fig. 22 Middle cabin door reinforcement 10.

[0067] From the above prefabrication method of modular cabins, it can be seen that the present invention adopts the bottom square tube and its temporary reinforcement support as the cabin foundation, which is a pentahedral structure. The floor is installed on the cruise ship deck in the later stage. On the one hand, it is better integrated with the overall cruise ship, and on the other hand, it reduces the lifting weight of the modular cabin. Secondly, the bottom square tube and the wall panel units are installed in order starting from the wet area unit, which is more convenient to adjust the size. Thirdly, components such as wall panels, ceilings and cabin doors are provided with reinforcements to meet the structural stability of the cabin when it is lifted or pushed. In addition, in this embodiment, the spacing of fasteners (mainly screws) and the construction joints of the clamping parts have specific technical parameters to better meet the structural stability requirements when the cabin is lifted or pushed.
