4. Design Requirements
4.1 Railing Height:
4.1.1 Guardrail Systems:
4.1.1.1The fabricated height of a guardrail system, measured from its top surface to the finished floor level, shall be a minimum of 1.07 m (42 in.). When variations in the evenness of the finished floor will result in individual height measurements of the installed guardrail system to be less than 1.04 m (41 in.), the fabricated height of the guardrail system shall be increased accordingly.
护栏系统的组装高度,从最顶端面至地表至少要应该达到1.07米(即42英寸)。根据楼梯地表平整度的不一会导致个别测量高度低于1.04米(即41英寸)时,装配高度也应该随着增加。
4.1.1.2 Within an individual dwelling unit, the required railing height is reduced.
对于个人住宅使用时,相应栏杆高度可随之降低。
(a) (a ) Where the vertical distance between adjacent finished floor levels is less than 1.83 m (72 in.), the height shall be a minimum of 0.81 m (32 in.). When variations in the evenness of the finished floor will result in individual height measurements of the installed guardrail system to be less than 0.79 m (31 in.), the fabricated height of the guardrail system
shall be increased accordingly.
当相邻楼梯面的垂直距离少于1.83米(即72英寸)时,栏杆高度应至少要达到0.81米(即32英寸)。根据楼梯地表平整度的不一会导致个别测量高度低于0.79米(即31英寸)时,装配高度也应该随着增加。
(b ) Where the vertical distance between adjacent finished floor levels is a minimum of 1.83 m (72 in.), the height shall be a minimum of 0.86 m (34 in.). When variations in the evenness of the finished floor will result in individual height measurements of the installed guardrail system to be less than 0.84 m (33 in.), the fabricated height of the guardrail system
shall be increased accordingly.
当相邻楼梯面的垂直距离至少达1.83米(即72英寸)时,栏杆高度也应至少要达到0.86米(即34英寸)。根据楼梯地表平整度的不一会导致个别测量高度低于0.84米(即33英寸)时,装配高度也应该随着增加。
4.1.1.3 In public assembly, elementary school, and multiple family occupanies where the vertical distance between stair and adjacent levels is more than 4.1 m (20 ft.), the required railing height shall be increased beyond that given in 4.1.1.1.
在公共场所,如小学以及居民住宅处楼梯以及相邻水平面的垂直距离会大于4.1米(即20英尺),这样的话栏杆的高度也应该对应调整(比4.1.1.1所描述的调整高低要高出很多)
4.1.1.4 For balconies in public-assembly occupancies, the required railing height in front of the first row of fixed seats shall be reduced to 0.66 m (26 in.) provided adequate safety is established by the designer and approved by the authority having jurisdiction; however, it shall be a minimum of 0.91 m(36 in.) at aisle ends and a minimum of 1.07 m (42 in.) where aisle steps occur.
至于公共阳台围栏要求,固定位置的首排栏杆高度应减至0.66米(即26英寸),前提是安全系数在设计师要求的合理范围内以及通过了权威部门设定的限度内。尽管如此,栏杆的高度在过道尾端也应达到0.91米(即36英寸),并且过道的阶梯栏杆高度也应达到
1.07米(即42英寸)。
4.1.2 Handrails and Stair-Rail Systems:
4.1.2.1 In corridors, ramps, walkways, and enclosed stairways having a slope of at least 1 in 20, the height of the handrail of the stair-rail systems, measured from its top surface to the finished floor level or tread-nose line, shall be not less than 0.86 m (34 in.) nor more than 0.97 m (38 in.). When a stair-rail system is higher than 0.97 m (38 in.), a separate handrail shall be installed at a height of not less than 0.86 m(34 in.) nor more than 0.97 m (38 in.).
在倾斜的走廊,斜坡,过道以及封闭的楼梯里,20个扶手至少有一个扶手的高度,从最高处至楼梯面,最低不能低于0.97米(即38英寸),最高不能高过0.97米(即38英寸)。当楼梯栏杆高度高于0.97米(即38英寸),单独的扶手管安装高度应不低于0.86米(34英寸)且不高于0.97米(即38英寸)。
4.1.2.2 Where required and in childcare and educational facilities serving children under the age of 12 years, a second separate handrail shall be permitted to be installed at a mounting height of 24 to 28 in. (61
