Marine steel-made fireproof door easy to open

Abstract

The invention relates to a marine steel-made fireproof door easy to open. The door comprises a door frame and a door body. One side edge of the door body is installed on the door frame through hinges, a circle of sealing strip is installed at the inner side edge of the door body, and when the door body is closed, the sealing strip is attached to the door frame. The door body comprises a steel-made door plate and closure plates on the four sides, a plurality of parallel stiffeners are installed between a front door plate body and a rear door plate body in a welded mode, a calcium metasilicate plate layer is installed on the inner side of the front door plate body, and the portion between the calcium metasilicate plate layer and the rear door plate body is filled with ceramic wool. A locking mechanism is arranged between the door body and the door frame and installed on the inner side of the door body, the locking mechanism comprises four connecting rods which are connected end to end to form a rectangle, and the connection rods are connected through triangular plates; the two ends of each triangular plate are connected with the two ends of the adjacent connection rod respectively, and the other end of each triangular plate is hinged to the inner wall of the door body.

Description

technical field [0001] The invention relates to the field of ships, in particular to a ship-used easy-to-open steel fireproof door. Background technique [0002] At present, the cabin doors on ships or civilian ships are common fire doors. This common fire door includes a door frame and a door panel, and the same vertical edge of the door frame and the door panel is hinged together by means of a hinge. A fireproof strip and a sealing strip are arranged between the door frame and the door panel, and the fire prevention function is realized through the fireproof strip and the sealing strip. Wherein, the door frame and the door panel are cavity structures formed by bending and welding steel plates. Since the door frame and door panel are cavity structures made of bent and welded steel plates, there is no filler in the inner cavity of the door frame and door panel, and the sound insulation performance is poor, which makes it difficult to prevent the surrounding noise from bein...

AI Technical Summary

Problems solved by technology

Since the door frame and door panel are cavity structures made of bent and welded steel plates, there is no filler in the inner cavity of the door frame and door panel, and the sound insulation performance is poor, which makes it difficult to prevent the surrounding noise from being transmitted to the cabin, so that the cabin is affected by the surrounding environment. The impact of environmental interference is greater

In addition, the fire door is usually locked on one side with the door frame, and the lock is not firm, so it cannot be well adapted to marine occasions. The fire door with a complicated locking structure takes a long time to open and is inconvenient to use.
