Description

Technical Field

[0001] The utility model relates to the field of cabin penetration structures, in particular to a cabin B-class fireproof cable cabin penetration structure. Background Art

[0002] In recent years, with the growing prosperity of the domestic and foreign shipbuilding and offshore engineering industries, and the transformation to high value-added ships, the quality and quantity of passenger rooms have put forward higher requirements. Ship cables pass through fire curtains and other Class B fire separations. The on-site construction interface includes interior outfitting and electrical outfitting. The traditional construction method is that after the ship's main section is closed, the regional stage follows the steps: first weld the fire curtain hanger, weld Class B electrical penetrations on the fire curtain, and use nails to install and fix Class B insulation cotton. After the above work is completed, the cable laying work of the corresponding node can be carried out. Large-scale ship and offshore engineering projects have a tight construction period, and the cross-professional work is complicated. There are many guest rooms and public areas, and there are many Class B separations such as fire curtains. The installation and construction progress of the fire curtain essentially affects the laying progress of the cable. The cable laying is constrained by the construction progress of the retaining ring on the fire curtain, which is not conducive to the overall construction efficiency.

[0003] The patent application with publication number CN117091008A discloses a B15-resistant bulkhead penetration piece connection structure and a method for installing the penetration piece, which are used in ships. The ships include bulkheads, and the fire protection grade of the bulkheads is B15. The B15-resistant bulkhead penetration piece connection structure includes a tubular penetration piece, which penetrates the bulkhead, an insulating protective sleeve, which is sleeved on the tubular penetration piece; a sealing component, which is arranged at the connection between the tubular penetration piece and the bulkhead, and the sealing component is located inside the insulating protective sleeve; the sealing component includes a pipe sleeve clamp and a sealing filler, the sealing filler is arranged on the outer peripheral side of the tubular penetration piece, and the pipe sleeve clamp is arranged on the outer peripheral side of the sealing filler.
