Design method for reference lines for mounting outfitting piping system in inverse segment of cabin surface

Abstract

The invention discloses a design method for reference lines for mounting an outfitting piping system in an inverse segment of a cabin surface. The method comprises the following steps: the first step, establishing a three-dimensional reference, the intersection point of a shipboard side wall and the bow of a deck, and the intersection point of the shipboard side wall and a stern of the deck serve as the first management reference point a and the second management reference point b separately, and the intersection point of a cross wall and the midship of the deck serves as the third management reference point c; the second step, drawing waterline marks, drawing deck minus 1000mm waterline marks on the shipboard side wall, the cross wall and a longitudinal bulkhead by using a gradienter; the third step, based on the segment standard three-dimensional measurement data report, drawing corresponding half-width reference lines from the shipboard side wall to the midship by 200mm and 10m straight thatching line auxiliary reference lines on the framework surface of the deck, and drawing bow-end and stern-end frame plus or minus 200mm end reference lines on the corresponding positions. By adopting the design method, the outfitting piping system can be highly precisely mounted in the segment of the cabin, and the purposes of cancelling joining and correcting pipes on site are realized for most of the segments. The design method is high in precision and the piping system can be highly precisely mounted in the segment of the cabin.

Description

technical field [0001] The invention belongs to the technical field of shipbuilding, and in particular relates to a design method for a datum line used for installing outfitting piping systems in an anti-state section of an engine room curved surface. Background technique [0002] In the process of ship construction, the difficulty in the management of the installation accuracy of the engine room piping system is the accuracy problem, which is also a key bottleneck affecting the efficiency of ship construction. Due to the problems of weak structure and poor accuracy in the section of the cabin. However, the engine room is the area with the densest pipe system, and a large number of closed pipes between sections cannot be standardized according to conventional processes. Design and manufacture according to the finished product in time, because the precision of the pre-installed piping system is not up to the standard, a large number of closed pipes of the finished products a...

Due to the weak structure and poor accuracy of the cabin segmentation

However, the engine room is the area with the densest pipe system, and a large number of closed pipes between sections cannot be standardized according to the conventional process.

Carry out design and production according to the finished product in time. Since the precision of the pre-installed piping system cannot be reached, a large number of finished closed pipes are often scrapped, and the existing school pipes need to be remade, which affects the efficiency of ship construction and increases the construction cost.
