Description

Technical Field

[0001] This utility model belongs to the field of ship interior technology, and more specifically, it relates to a ship interior sound insulation and vibration reduction structure. Background Technology

[0002] With the development of the shipbuilding industry, ships are becoming larger and larger, and the requirements for interior decoration are also increasing. Currently, ships do not have high requirements for personnel living quarters, often only for fire safety. The common method for ship interior decoration is to directly lay fireproof decking material on the deck. This method has poor sound insulation and vibration isolation effects, resulting in high cabin noise and failing to achieve good results.

[0003] Existing technology includes a technology entitled "A Flexible Connection Structure for Ship Interior Decorative Panels," with publication number CN217649608U. This technology discloses a flexible connection structure for ship interior decorative panels, belonging to the field of ship interior decorative panel installation, and solves the problems of noise and damage easily caused by the rigid connection of existing ship interior decorative panels. This flexible connection structure includes a top groove and a bottom groove. The bottom groove connects to the ship's deck, and an interior decorative wall panel is inserted between the bottom groove and the top groove. A buffer element is provided in the bottom groove below the interior decorative wall panel. The top groove is connected to the ship's bulkhead via a flexible connection assembly, and an interior decorative ceiling overlaps the inner side of the top groove. This utility model's flexible connection structure for ship interior decorative panels can minimize cabin noise caused by mechanical vibration and extend the service life of the interior decorative panels.

[0004] However, this technology does not address the technical issues and solutions of this application. Utility Model Content
