Problems solved by technology

This segmented construction method not only has a lot of times of loose lifting, but also has poor precision of loose lifting, and it is very easy to cause the installation angle accuracy of the rib plate frame to be insufficient, which leads to the problem that the longitudinal members of the outer plate cannot be installed accurately, which makes the construction personnel need a long time To adjust to meet the requirements of precision management, not only the construction is difficult, but also the construction period is long, which greatly affects the efficiency of segmented construction

Abstract

The invention provides a quick construction method for a lower water tank subsection of a ship. The quick construction method comprises the steps that S1, longitudinal panels and longitudinal webs are machined; s2, outer plate longitudinal bones and inclined top plate longitudinal bones are obtained; s3, obtaining an insole assembly; s4, machining each rib plate frame; s5, obtaining an inclined top plate and an outer plate; s6, the inclined top plate and the inclined top plate longitudinal bone are hoisted; s7, the inner bottom assembly is hoisted; s8, a rib plate frame is hoisted; s9, outer plate longitudinal bones are hoisted; s10, hoisting an outer plate; in the production and machining process, the positioning datum lines are additionally arranged on all the parts and serve as positioning folding lines for follow-up small assembly installation, middle assembly installation and large assembly hoisting, through line-to-line positioning installation, the installation precision is guaranteed, the construction difficulty is lowered, and the production efficiency is improved. The problem that the installation position of the outer plate longitudinal bone is repeatedly adjusted due to the fact that the installation angle precision of the rib plate frame is not enough in the traditional segmented construction process is effectively solved, the segmented construction efficiency is greatly improved, and quick segmented construction is achieved.

Description

technical field [0001] The invention belongs to the technical field of ship building, and in particular relates to a segmented rapid construction method of a water tank below a ship. Background technique [0002] The traditional construction method of the water tank section under the ship is to reverse the sloping roof as the base surface, and then loosely lift the sloping bottom longitudinals, inner bottom plates, rib frames, longitudinal girders, inner bottom ribs, outer plate longitudinals, The outer panels, complete the entire segmented construction. This segmented construction method not only has a lot of times of loose lifting, but also has poor accuracy of loose lifting, and it is very easy to cause the installation angle accuracy of the rib plate frame to be insufficient, which leads to the problem that the longitudinal members of the outer plate cannot be installed accurately, which makes the construction personnel need a long time To adjust to meet the requirement...
