船用斜梯的选型设计和布置

Type Selection and Arrangement Design of Marine Inclined Ladder

结合近年来参与的中小型游船、快艇及公务船的设计项目,分析船用斜梯的形式、斜梯倾斜角、梯口长度、缓步平台、斜梯处的净空高度、脱险通道和防火安全等方面的问题。采用图示分析,直观地阐述斜梯设计布置过程中存在的问题,避免这些问题在后续送审设计、生产设计甚至在船体建造后才出现而过于被动。

Combined with the design projects of some small&medium-sized tourist ships,speedboats and official ships in recent years,this paper analyzes the problems that should be paid attention to the form of marine inclined ladder,inclined angle of inclined ladder,length of ladder mouth,length of slow step platform and clearance height at inclined ladder,the requirements of escape passage and fire safety.By using graphical analysis,the problems existing in the design and layout of inclined ladders are intuitively explained,so as to avoid these problems from appearing too passive in the subsequent design submitted for approval,production design and even after the hull construction.
