Problems solved by technology

With the implementation of the "Noise Level Rules on Ships", for some cabins of the ship, the use of ordinary fire-resistant dressings cannot achieve the required sound insulation level, so a floating floor with a high sound insulation index of 56dB is required for the overall structure.

Abstract

The invention relates to a marine high-sound-insulation floating floor structure. The structure comprises a damping coating I arranged on a steel deck, and ceramic wool dividing strips which are arranged on the damping coating I and are close to a steel trunk bulkhead, a refractory deck dressing layer is arranged on the portion, between the ceramic wool dividing strips, of the damping coating I, arock wool board is arranged on the refractory deck dressing layer, a galvanized steel sheet I is arranged on the rock wool board, a damping coating II is arranged on the galvanized steel sheet I, a galvanized steel sheet II is arranged on the damping coating II, and the upper surface of the galvanized steel sheet II and the upper end faces of the ceramic wool dividing strips are at the same level. The structure is reasonable in structure arrangement, good in damping and noise reduction effect and high in resistance to deformation, and the fire rating reaches A-60 level.

Description

technical field [0001] The invention relates to a marine floor structure, in particular to a marine deck covering structure. Background technique [0002] According to the requirements of SOLAS Convention on the Safety of Life at Sea and its ship regulations, covering layers with different fire protection levels must be laid on marine engineering and ship decks, and this covering layer becomes deck covering. Deck covering is a covering material laid on the deck of a ship. It mainly plays the role of heat insulation, noise reduction, and anti-skid. According to different needs, ships must use different types of deck coverings. All ship coverings must have heat insulation, Noise reduction, smoke elimination, corrosion resistance and other conditions. With the implementation of the "Noise Level Rules on Ships", for some cabins of the ship, ordinary fire-resistant dressings cannot achieve the required sound insulation level, so a floating floor with a high sound insulation inde...
