Enclosure bulkhead board access door for ship

Abstract

The invention relates to an enclosure bulkhead board access door for a ship. The enclosure bulkhead board access door comprises a composite rockwool panel enclosure bulkhead board (1) and an access door board (3), wherein a door opening is arranged in the composite rockwool panel enclosure bulkhead board (1), a rubber plate framework (1.1) is embedded on the periphery of the door opening, a door frame (2) and a door press frame (4) are wrapped outside the rubber plate framework (1.1), and smoke prevention strips (5) are compounded on the periphery of the back side of the access door board (3). The door press frame (4) comprises a back horizontal-pressing frame (4.1), wherein the back horizontal-pressing frame (4.1) is arranged on the back side of the rubber plate framework (1.1), one side of the back horizontal-pressing frame (4.1) away from the access door board (3) is bent forward at 180 degrees and then is tightly compounded on the back side of the back horizontal-pressing frame (4.1), one side of the back horizontal-pressing frame (4.1) close to the access door board (3) is bent forward at 90 degrees to form a lateral-pressing frame (4.2), and the lateral-pressing frame (4.2) is arranged on the nearby side of the rubber plate framework (1.1). The enclosure bulkhead board access door for the ship is high in fireproofing grade and free of rough edges at the position of the door frame.

Description

(1) Technical field [0001] The invention relates to an overhaul door for a ship's coaming board. It is used on the composite rock wool board of the cabin coaming board that needs to be overhauled. It belongs to the field of ship technology. (2) Background technology [0002] In order to facilitate maintenance, it is usually necessary to install an inspection door on the composite rock wool board wall panel inside the cabin. Wall panels have strict fire code requirements. After the inspection door is installed, the overall fire protection level of the composite rock wool board must still be achieved. Before the present invention is made, there are following deficiencies in the past inspection door of ship's coaming board: [0003] 1. Since there are no smoke-proof strips around the inspection door, the fire smoke generated by combustion will leak out from the gap between the inspection door and the door frame, so the fire protection level is low, and its fire resistance c...

AI Technical Summary

Problems solved by technology

[0003] 1. Since there are no smoke-proof strips around the inspection door, the fire smoke generated by combustion will leak out from the gap between the inspection door and the door frame, so the fire protection level is low, and its fire performance cannot reach B15 level

[0004] 2. Because there is no door pressure frame at the door opening of the composite rock wool board wall panel, after the door opening is sawn, there will be burrs on the door frame, resulting in poor overall aesthetics of the marine wall panel inspection door

[0005] 3. Since the maintenance doors on the composite rock wool board wall panels are usually installed by the manufacturer, they cannot be installed on site, which brings great inconvenience to the positioning of the shipyard.
