The doorsill of the fire door is 15 mm high only, the doorsill can be flush with the deck dressing on the ship, the customers dragging the luggage aboard can pass through the doorsill conveniently, and the degree of satisfaction of the customers is improved.

Description

(1) Technical field [0001] The invention relates to a fireproof door of ships. It belongs to the technical field of ship decoration. (2) Background technology [0002] In the past, the frame types of fire doors of ships were as follows: Figure 1~4 As shown, this fire door has the following disadvantages: [0003] 1) On fire doors of the same level, the fire threshold is protruding outside. After a long time of trampling, the lower threshold is easy to deform and the rubber strip is easy to fall off. [0004] 2) On fire doors of the same level, the lower sill of the fire door will affect the passage of pedestrians, especially the passage of customers on passenger ships with luggage, and it is inconvenient, especially manual wheelchairs for the disabled cannot pass through at all, which reduces the number of customers. satisfaction. [0005] 3) On fire doors of the same level, the threshold of the fire door is protruding outside. Relatively speaking, the cost of materials ...
