However, it should be understood that these descriptions are only exemplary and are not intended to limit the scope of the present invention.

It should also be understood that the term "and / or" used herein refers to and includes any or all possible combinations of one or more associated listed items.

[0052] In order to better understand the technical solution of the present invention, the present invention is described in detail below with reference to the accompanying drawings.

[0053] The present invention provides a method for constructing a container ship engine room bottom section, which specifically comprises the following steps:

[0054] S1, ship design stage, the cabin bottom section is divided into outer plate segment 5, outer plate middle assembly 1, inner bottom plate assembly 2, door frame assembly 3 and platform assembly 4;

[0055] The inner bottom plate assembly 2 is divided into a plurality of inner bottom plate subassemblies and an inner bottom plate segment by taking the position of the longitudinal wall plate of the inner bottom plate assembly 2 as a dividing line.

[0056] S2, manufacturing a segmented tire frame, wherein the tire plate size of the segmented tire frame should be larger than the outer plate size of the completed cabin bottom section, and the shape of the tire plate should also be the same as the outer plate shape of the completed cabin bottom section.

[0057] S3, build the outer plate segment 5 and the outer plate middle assembly 1 on the segmented frame at the same time, and the outer plate segment 5 should be connected with the outer plate of the outer plate middle assembly 1; build the inner bottom plate assembly, the door frame assembly 3 and the platform assembly 4 in the opposite state on other frames or on the ground.

[0058] Constructing the outer plate segment 5 and the outer plate middle assembly 1 on the same frame means that the outer plate segment 5 and the outer plate middle assembly 1 are constructed on the same frame. The two can be constructed simultaneously or one after the other. However, after the construction of both is completed, the outer plate segment 5 should be connected with the outer plate of the outer plate middle assembly 1.

[0059] Specifically, the specific steps for constructing the outer panel segment on the segmented tire frame are as follows: first, laying a plurality of outer panel panels on the tire frame surface of the segmented tire frame so that the outer panel panels are in contact with the tire frame surface; then, a groove with an opening toward the frame surface is opened at the joint position between two adjacent outer panel panels, and the groove angle is preferably 20°; then, the joint seam between the two adjacent outer panel panels is welded by downward welding to form the outer panel segment 5.

[0060] The specific steps of assembling the outer plate on the segmented frame are as follows: first, the assembled outer plate 11 is made on the segmented frame. The assembled outer plate 11 is also an outer plate segment, which is spliced ​​by multiple outer plates. The manufacturing method of the assembled outer plate is the same as the manufacturing method of the outer plate segment. When making the assembled outer plate, its edge should be connected with the outer plate segment;

[0061] Then, a plurality of first T-shaped bars 12 and a plurality of first ribs 13 are arranged in parallel on the assembled outer plate 11, and the first T-shaped bars 12 and the first ribs 13 are perpendicular to each other;

[0062] Then, the high seawater box 14 and the deck support column 15 are fixed on the assembled outer plate 11;

[0063] Finally, a first lifting ring 16 is preset on the high seawater box 14 in advance, and the first lifting ring 16 is used when the cabin bottom section is subsequently lifted to close the cabin bottom section 6 with other sections.

[0064] The specific steps of reverse construction of the inner bottom plate assembly 2 are as follows: first, construct an inner bottom plate segment on other tire frames or the ground, the inner bottom plate segment is also spliced ​​by multiple inner bottom plates, and its manufacturing method is similar to the manufacturing method of the above-mentioned outer plate segment, that is, first lay and splice multiple inner bottom plates on other tire frames or the ground, and open a groove with an opening facing the frame surface at the splicing position between two adjacent inner bottom plates, and the groove angle is preferably 20°; then, the splicing seam between the two adjacent inner bottom plates is welded by downward welding to form an inner bottom plate segment 21, and finally, a plurality of second T-shaped materials 23 are vertically fixed on the inner bottom plate segment 21, and the spacing between the two adjacent second ribs in the stress concentration area is smaller than the spacing between the two adjacent second ribs in the non-stress concentration area. Preferably, the spacing between the two adjacent second ribs in the non-stress concentration area is more than twice the spacing between the two adjacent second ribs in the stress concentration area;

[0065] While manufacturing the inner bottom plate segment 21, each inner bottom plate sub-assembly 22 can be simultaneously manufactured. Each inner bottom plate sub-assembly 22 has the same structure, including a longitudinal wall plate 24 and a second rib plate 26. For a single inner bottom plate sub-assembly, the manufacturing steps are as follows: first, the longitudinal wall plate 24 is laid flat on other tire frames or the ground, and then, a plurality of multi-stage second rib plates 26 are vertically fixed on the longitudinal wall plate 24, and the second rib plates 26 are perpendicular to the second T-shaped material 23;

[0066] After each inner bottom panel sub-assembly 22 is constructed, a hoisting reinforcement 27 spanning all ribs is fixed on each inner bottom panel sub-assembly 22. The hoisting reinforcement 27 can be fixed on one or both sides of the rib. The hoisting reinforcement 27 is used to reinforce the structure during the closing process of the inner bottom panel sub-assembly 22 to avoid the rib position from being offset or the rib from being deformed.

[0067] Then, according to the inner bottom plate assembly design drawing, the sewage pipe 25 is pre-laid at the corresponding position of the inner bottom plate segment 21;

[0068] Then, all the inner bottom plate sub-assemblies 22 are turned over 90° (i.e., turned over 90° counterclockwise) and then hoisted and placed in the corresponding positions on the inner bottom plate segment 21 in sequence, and closed to form the inner bottom plate assembly 2 (after the inner bottom plate sub-assemblies are closed, the hoisting reinforcement on each inner bottom plate sub-assembly needs to be removed);

[0069] Finally, a second lifting ring 28 is installed on the inner bottom plate assembly 2. The second lifting ring 28 is used when the inner bottom plate assembly 2 is closed with the outer plate segment 5, and can also be used when the cabin bottom segment 6 is subsequently lifted to close the cabin bottom segment 6 with other segments. Preferably, the second lifting ring 28 is installed on both sides of the second rib plate on the bow side of the inner bottom plate assembly 2, that is, Figure 2 The second rib from left to right is shown.

[0070] The construction process of the door frame assembly 3 and the platform assembly 4 is a conventional construction process, which will not be described in detail here.

[0071] S4, turning the inner bottom plate assembly 2 over by 180° and placing it upside down on the outer plate segment 5.

[0072] S5, hoist and fix the door frame assembly 3 on the top of the inner bottom plate assembly 2, and hoist the platform assembly 4 on the bow side of the outer plate middle assembly 1 and the inner bottom plate assembly 2 to be combined with the outer plate middle assembly 1 and the inner bottom plate assembly 2 to obtain the cabin bottom section 6.

[0073] It should be clear that the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.
