Bottom stool structure and ship

Abstract

The invention belongs to the technical field of groove type bulkhead bottom stool design, and discloses a bottom stool structure and a ship, the bottom stool structure comprises bottom stool side plates, a bottom stool top plate and a bottom stool partition plate, the bottom stool side plates comprise a first side plate and a second side plate, and the second side plate and the first side plate are arranged in a spaced mode, installed on a cargo hold inner bottom plate and far away from the cargo hold inner bottom plate in the first direction; the first side plate gradually gets close to the second side plate, and the first direction is perpendicular to the cargo hold inner bottom plate; the bottom stool top plate is erected on the first side plate and the second side plate and is configured to support the groove-shaped cabin wall; the bottom stool partition plate is clamped between the first side plate and the second side plate, the two opposite sides of the bottom stool partition plate are fixedly connected to the first side plate and the second side plate, the top of the bottom stool partition plate is fixedly connected to the bottom stool top plate, and load reducing holes are formed in the bottom stool partition plate. According to the bottom stool structure, by adjusting the original structure, stress concentration of the partition plate can be avoided, the risk of structural damage is reduced, structural integrity and reliability of the bulkhead between the cargo hold and the ballast tank are guaranteed, and potential safety hazards such as leakage are prevented.

Description

technical field [0001] The invention relates to the technical field of trough bulkhead bottom stool design, in particular to a bottom stool structure and a ship. Background technique [0002] In addition to flat bulkheads, trough bulkheads are also used on some ships. The corrugated bulkhead is generally made of steel plate, and the corrugated bulkhead is bent to replace the function of the stiffener. Corrugated bulkheads are widely used on various cargo ships. In order to obtain better structural strength, the lower end of the corrugated bulkhead is usually provided with a bottom stool structure. When the cargo loading conditions of the cargo holds on both sides of the corrugated bulkhead are different, or when the cargo is shaken when the ship is sailing, the cargo loads on both sides of the corrugated bulkhead are different in magnitude and cannot offset each other. The corrugated bulkhead will bear the bending moment load as a whole, and this load will be transmitted t...

Problems solved by technology

The disadvantage of this method is that increasing the thickness of the plate increases the amount of welding filling, and the welding residual stress increases accordingly. The thicker the plate, the lower its strength and more internal defects, so the thicker plate is more prone to fatigue cracks

On the other hand, the total weight of the ship and the maximum weight of the cargo that can be transported are fixed, and the increase in the structural weight will inevitably reduce the weight of the cargo that can be transported; due to the increase in the construction workload, the efficiency of ship construction is reduced
