Benefits of technology

This invention improves upon existing methods for attaching ships' beams on shipping vessels by reducing stress concentration at specific points along their length without adding extra weight or making it difficult to pass through traffic. It also increases its durable life while maintaining high efficiency compared with traditional designs that require added reinforcement materials like steel plates.

Problems solved by technology

This patented technical problem addressed by this patents relates to reducing stresses caused during boat movements while maintaining stability for transportation purposes without increasing its size beyond certain limits.

Embodiment Construction

[0032] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0033] see Figure 5-11 , an anti-fatigue layout structure for ship double bottom openings, square holes are respectively opened on the left and right sides of the pillars on the inner bottom of the ship double bottom, a rectangular metal box is arranged in the square hole, and the rectangular box body The watertight floors between the sides and the double bottom of the ship and the sides of the columns are welded and fixed.

[0034] see Figure 6 , In this embodiment, a watertight structure is formed between the rectangular metal box, the inner bottom and the uprights.

[0035] see Figure 6 , in this embodiment, the pillar is in the shape of a rectangular body.

[0036] see Figure 6 , in this embodiment, the width of the square hole in the axial direction of the hull is greater than the width of the pillar.

[0037] see Figure 6 , in...

Abstract

The invention relates to an opening anti-fatigue arrangement structure and method of ship double bottoms and belongs to the technical field of ship upright arrangement structures. The opening anti-fatigue arrangement structure of the ship double bottoms is characterized in that square holes are formed in the positions, located on the left side and the right side of an upright, at the inner bottom of the ship double bottoms correspondingly and each internally provided with a rectangular metal box body, and the side faces of the rectangular box bodies are fixed to watertight ribbed plates between the ship double bottoms and the side face of the upright in a welded mode. According to the opening anti-fatigue arrangement structure and method of the ship double bottoms, flexible connecting of the upright and the double bottoms of the ship is achieved, and the phenomenon that the local stress is overlarge when the box bodies are slightly transformed is avoided; and the anti-fatigue strength of the connecting positions of the upright and the double bottoms are greatly promoted, and reliability is promoted.
