Ship window structure

Abstract

The invention discloses a ship window structure which is mounted and fixed on a bulkhead of a ship, and a mounting opening is formed in the bulkhead; the ship window structure comprises a window body;a mounting connecting structure which is connected and fixed between the window body and the bulkhead; the mounting connecting structure is provided with a first connecting frame fixedly arranged onthe bulkhead, and the first connecting frame extends in the direction perpendicular to the bulkhead at the mounting opening and is symmetrically arranged inside and outside. By arranging the mountingconnecting structure, the stress level of the mounting opening area of the bulkhead is effectively reduced, the strength problem of the mounting opening is solved, the structural strength of the window structure after mounting is improved, and the stress capacity and firmness after mounting are improved. The first connecting frame is arranged to be in a barrel shape symmetrically arranged in the inner-outer direction, the stress area in the inner-outer direction is increased by extending in the inner-outer direction, the structural strength of the mounting connecting structure is improved, andit is guaranteed that the structural strength of the ship bulkhead is improved after the window structure is installed.

Description

technical field [0001] The invention belongs to the technical field of ships, and in particular relates to a window structure of a ship. Background technique [0002] At present, during the design and construction of ships and offshore engineering platforms, windows are provided as standard components by relevant manufacturers according to the required size. Marine windows should be integrated with their glass and window covers to effectively ensure watertightness or airtightness. Require. The outer frame of the window is connected and fixed with the hull, and the commonly used connection method is to use single-sided fillet welding to connect the window with the hull structure as a whole. This window installation method simply meets the installation requirements, and the welding strength at the joint is very low, which poses a relatively large safety hazard. [0003] The function and layout requirements of offshore engineering platforms are getting higher and higher, and ...

This window installation method simply meets the installation requirements, and the welding strength at the joint is very low, which poses a large safety hazard

[0003] The function and layout requirements of offshore engineering platforms are getting higher and higher, and the size of windows is getting bigger and bigger, resulting in a significant reduction in the shear bearing area of ​​the hull structure, which greatly reduces the strength of the hull structure, especially at the corners of the window openings , there is a large stress concentration phenomenon, which has a great influence on the strength and fatigue of the structure

On the other hand, windows are no longer limited to non-load-bearing secondary structures. Windows are also required to be installed on many main load-bearing bulkheads to meet the functional requirements of ships and platforms. For these load-bearing tanks The wall, especially the bulkhead that bears a large dynamic load, is prone to fatigue cracks if the existing window structure and single-side fillet welding connection form are used, which reduces the fatigue life of the structure and cannot meet the normal strength and fatigue requirements of the structure. At the same time, when the load-bearing bulkhead is deformed by force, it is easy to deform the window frame, forming extrusion and shearing on the window glass, causing the window glass to break
