Abstract

The invention discloses a winding staircase arranged between an upper deck and a lower deck of a chemical ship. The winding staircase is made of stainless steel materials and comprises a vertically-placed central column connected with the upper deck and the lower deck; a plurality of vertically-placed pedals are arranged on the outer circumference of the central column in a spiral mode; one side of each pedal is connected with the central column, and anti-skid lines are arranged on the upper surfaces of the pedals. Pedals of the winding staircase are spirally arranged on the outer circumference of the central column, so that the occupied space of a cabin is greatly reduced, and the requirement of sailors for quickly getting on and off the deck is met; the winding staircase is made of the stainless steel materials, anti-skid lines are arranged on the upper surfaces of the pedals, the firmness and the safety of the winding staircase are improved, the winding staircase can be fused with office built-in arrangements, and meanwhile the office built-in texture can be improved.

Description

technical field [0001] The invention relates to the technical field of shipbuilding, in particular to a coil ladder arranged between upper and lower decks of a chemical tanker. Background technique [0002] On a 55,600-ton chemical tanker, in order to facilitate the crew to move between the upper and lower decks in the cabin, it is necessary to arrange ladders between the ship's office on the upper and lower decks and the cargo control room and deck office to facilitate direct access. The ladders in the existing cabins are generally straight upwards or downwards. The ladders occupy a large space, thereby reducing the usable space in the cabin; at the same time, the inclination angle of some straight ladders is too large. Straight ladders are uncomfortable. Contents of the invention [0003] The object of the present invention is to overcome the defects in the prior art and provide a coil ladder installed between the upper and lower decks of a chemical tanker which has a s...
