Embodiment Construction
[0023] The preferred embodiments of the present invention are given below in conjunction with the accompanying drawings to describe the technical solution of the present invention in detail.
[0024] Such as figure 1 and figure 2 As shown, the present invention provides a kind of bow subsection welding method, and it comprises:
[0025] S1. First make a horizontal tire frame, place the horizontal tire frame on the ground, and place a plate 5 horizontally on the horizontal tire frame, and position and weld a middle longitudinal truss 3 and a longitudinal rib 2 on the platen 5 respectively , and make the middle longitudinal girder 3 and the longitudinal rib 2 form a T-shaped butt joint. Among them, the parts of positioning and welding a middle longitudinal girder 3 and a longitudinal rib 2 respectively on the platform 5 are prior art, and will not be repeated here.
[0026] S2, then a bow frame 1 and platform 5 are assembled and welded; wherein, the bow frame 1 is made up of...

The invention discloses a segmental assembling and welding method of a stem, which comprises the following steps: S1. a medium longitudinal girder and a longitudinal rib plate are respectively located and welded on a table plate, and the medium longitudinal girder and the longitudinal rib plate are abutted in a T shape; S2. a stem frame is assembled and welded with the table plate; S3. and finally, the stem frame is assembled with multiple longitudinal bone T-rank plates, wherein the stem frame at least comprises a longitudinal plate, a lower rib plate and multiple baffle plates arranged on the lower rib plate in an interval mode; the longitudinal plate and the lower rib plate are vertically arranged; the longitudinal plate is inserted among the baffle plates; and the table plate is flatly laid on the ground before the step S1. The method has the advantages that the existing working high above the ground is changed into the assembling and welding on the flat ground, and the welding direction is well improved, thus the quality of the welding is guaranteed, the progress of the construction is accelerated, the working efficiency is enhanced, and the safe factor is greatly enhanced atthe same time.
Description
technical field [0001] The invention relates to a construction method of a bow, in particular to a method for installing and welding bow segments. Background technique [0002] Hull subsection construction is an important part of the entire ship construction, and it is also an intermediate product of the entire ship construction. Although the fore and aft subsections occupy a small number in each ship type, due to its complex structure, there is a high degree of difficulty in construction. Long period and so on. The existing 297,000-ton bow section construction method is usually to make the platform first, then the longitudinal ribs and the platform are positioned and welded, and the bow frame is built first, and then installed on the platform, because the bow is very high , in order to assemble and weld the longitudinal T-bars and the bow frame, several longitudinal T-bars need to be hoisted vertically to a high altitude, then dragged to the side of the bow frame by manpow...
