[0042] The specific embodiments of the present application will be further described in detail below in combination with the drawings and embodiments. The following embodiments are used to illustrate the present application, but are not used to limit the scope of the present application.

[0043] In the description of the present application, it should be understood that the directions or position relationships indicated by the terms “up”, “down”, “left”, “right”, “inner”, “outer” and the like in the present application are based on the directions or position relationships shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, and therefore cannot be understood as indicating or implying that the devices or elements referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as limiting the present application.

[0044] In the description of the present application, it should be understood that the terms "connected", "connected", "fixed" and other terms used in the present application should be understood in a broad sense, for example, it can be fixedly connected, or it can be detachably connected, or it can be integrated; it can be mechanically connected, or it can be weldedly connected; it can be directly connected, or it can be indirectly connected through an intermediate medium; it can be the internal communication of two elements or the interaction relationship of two elements, unless otherwise explicitly limited. For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0045] As shown in the preferred embodiment of the present application, Figure 1 A mounting method of a side rail of the preferred embodiment of the present application comprises:

[0046] 100: fit two panels, draw lines on the two panels;

[0047] 200: install webs on the panels according to the lines, so that the two panels form T-beams respectively;

[0048] 300: split the two T-beams;

[0049] 400: position and install the two T-beams on the side of the ship respectively;

[0050] 500: keep the distance between the two T-beams;

[0051] 600: weld the T-beams and the side of the ship, so that the two T-beams form a side rail.

[0052] It can be understood that the installation position of the web is indicated by drawing lines, and the method can effectively reduce the deformation amount of the T-beam, and ensure the perpendicularity of the web and the panel and the flatness of the panel; When installing, keep the distance between the two T-beams, so that the two T-beams are in a stable closed rigid constraint condition, improve the rigidity of the structure, and effectively reduce the welding deformation of the T-beam during installation.

[0053] As shown in the preferred embodiment of the present application, Figure 5 The T-beam 3 is installed on the side of the ship 2, and the distance between the two T-beams 3 is provided with a distance-keeping beam 1.

[0054] As shown in the preferred embodiment of the present application, Figure 2 Further, one of the panels is a first panel, the other panel is a second panel, one of the webs is a first web, and the other web is a second web. According to the lines on the panels, the installation of the web specifically comprises:

[0055] 201: on the side of the first panel away from the second panel, weld the first panel and the first web along the line;

[0056] 202: inserting the first web into the clamping groove, and setting the second panel away from the first panel on one side of the second panel upwardly;

[0057] 203: welding the second panel and the second web along the line on the side of the second panel away from the first panel.

[0058] It can be understood that, by fixing the first web through the clamping groove, the method can complete the welding of the second panel and the second web, thereby effectively reducing the deformation amount of the T-beam during welding, and ensuring the perpendicularity of the web and the panel and the flatness of the panel after the T-beam is welded.

[0059] In the above embodiment, the welding of the first web along the line specifically includes: welding the first panel and the first web by using a split-center symmetric rewelding method.

[0060] The welding of the second panel and the second web along the line specifically includes: welding the second panel and the second web by using a split-center symmetric rewelding method.

[0061] It can be understood that, by using the split-center symmetric rewelding method for welding construction, the stress and deformation in the welding process are effectively reduced, thereby reducing the welding deformation of the T-beam, and the post-welding correction workload is also correspondingly reduced.

[0062] Specifically, the distance-keeping treatment of the two T-beams specifically includes:

[0063] The two ends of the distance-keeping beam are respectively welded with the two T-beams.

[0064] It can be understood that, by using the distance-keeping beam to temporarily and rigidly fix the T-beam, the two T-beams are in a stable closed rigid constraint condition, the rigidity of the structure is improved, and the welding deformation during the installation stage of the T-beam is effectively reduced.

[0065] Further, after the T-beam and the side are welded to form the side sliding rail of the two T-beams, the distance-keeping beam is removed.

[0066] It can be understood that, removing the distance-keeping beam is conducive to the installation and welding of the intermediate box structure of the side sliding rail, completes the installation and welding of the side sliding rail and its attached structure, effectively prevents the hindering effect of other structures on the welding during the installation stage of the T-beam, and improves the quality and efficiency of the welding during the installation stage of the T-beam. Preferably, the other installation and welding work includes: installation and welding of the structural panel on the outside of the side sliding rail; installation and welding of the intermediate box structure of the side sliding rail.

[0067] As shown in FIG. 6, further, the welding of the T-beam and the side specifically includes: Figure 3

[0068] 601: installing the knee plates on the outside of the two T-beams; ​

[0069] 602: welding the right-angle weld between the knee plate and the web plate of the T-beam;

[0070] 603: welding the flat-angle weld between the knee plate and the side plate of the T-beam;

[0071] 604: symmetrically welding the flat-angle weld between the web plate of the T-beam and the side plate by using the symmetric centering back-welding method.

[0072] It can be understood that the T-beam outside structure corner weld is welded first, and then the corner weld between the T-beam web plate and the side plate is welded, so that the T-beam outside structure corner weld forms a good rigid fixation to the T-beam.

[0073] Further, the step of installing the web plate on the face plate according to the line, so that the two face plates form a T-beam and the time interval between the two T-beams is greater than 24 hours.

[0074] It can be understood that the 24-hour placement can fully release the welding stress, effectively reduce the deformation of the T-beam, and ensure the perpendicularity of the web plate and the face plate and the flatness of the face plate.

[0075] As shown in Figure 4 Further, the step of fixing the two face plates, drawing a line on the two face plates, specifically includes:

[0076] 101: fixing the two face plates;

[0077] 102: fixing the top surface and the bottom surface of the two face plates after being fixed by using the clamping code;

[0078] 103: drawing a line along the center line of the two face plates.

[0079] It can be understood that the use of the clamping code to fix the two face plates can ensure the perpendicularity of the web plate and the face plate and the flatness of the face plate after welding.

[0080] Preferably, after the side plate of the ship is completed, the two T-beams are respectively positioned and installed on the side of the ship.

[0081] It can be understood that by advancing the welding time of the side rail structure to the section stage, the corner weld of the side rail structure in the installation stage is mostly flat-angle weld, and the flat-angle weld has a large welding speed and small welding heat input, thereby shortening the construction period, reducing the welding deformation, and ensuring that the welding precision of the side rail meets the design requirements.

[0082] In summary, the embodiment of the present application provides a mounting method of the side rail, which indicates the mounting position of the web plate by the way of line drawing, can effectively reduce the deformation of the T-beam, and ensure the perpendicularity of the web plate and the face plate and the flatness of the face plate; when mounting, the distance between two T-beams is kept, so that the two T-beams are in a stable closed rigid constraint condition, the rigidity of the structure is improved, and the welding deformation of the T-beam in the mounting stage is effectively reduced.

[0083] The above merely describes the preferred embodiments of the present application, and it should be noted that those skilled in the art can make several improvements and replacements without departing from the technical principles of the present application, and these improvements and replacements should also be considered as the protection scope of the present application.
