According to the requirements of vibration reduction, noise reduction and fire prevention of ships, floating deck coverings or soft fireproof materials laid under steel plates are used instead of floating floors, which only passively play a part of vibration isolation and fire prevention, and cannot fundamentally actively reduce ship vibration and noise. In order to meet the requirements of the "Noise Level Rules on Ships" for multi-functional work boats and survey ships with higher technical content, they are generally imported and used from Switzerland, Germany and other foreign floating floors. Long, high cost, inconvenient maintenance

Abstract
The invention relates to the technical field of shock and noise reduction for ships, and more specifically, a floating floor, which is simple in design, convenient in construction, effectively shortens the shipbuilding cycle, and has various technical indicators that fully meet various indicators such as ship vibration and noise reduction, fire prevention, etc. Requirements: The noise index of the crew cabin and working area is lower than the maximum allowable noise level, the vibration is lower than the maximum allowable vibration level, the comfort level can reach the first grade, and the surface material meets the requirements of the SOLAS international convention for low flame spread, According to the special requirements of different parts of the ship, the fire rating can reach A60. On the deck, there are damping layer, constraining layer, rock wool II, galvanized steel plate I, damping layer, galvanized steel plate II and base dressing in order from bottom to top; Above, rock wool I is in contact with the damping layer, constraining layer, rock wool II, galvanized steel plate I, damping layer, galvanized steel plate II and the base dressing, and the water-blocking flat steel is in contact with rock wool I.
Description
technical field [0001] The invention relates to the technical field of shock absorption and noise reduction for ships and the like, and more specifically relates to a floating floor. Background technique [0002] The "Regulations on Noise Levels on Ships" approved by the IMO Maritime Safety Committee (MSC) of the International Maritime Organization and officially implemented on July 1, 2014, set strict index levels for vibration and noise in various cabins and parts of ships. According to the requirements of vibration reduction, noise reduction and fire prevention of ships, floating deck coverings or soft fireproof materials laid under steel plates are used instead of floating floors, which only passively play a part of vibration isolation and fire prevention, and cannot fundamentally actively reduce ship vibration and noise. In order to meet the requirements of the "Noise Level Rules on Ships" for multi-functional work boats and survey ships with higher technical content, t...
