剪刀楼梯宽度的要求有：踏步的尺寸一般应与人脚尺寸步幅相适应，同时还与不同类型建筑中的使用功能有关。踏步的尺寸包括高度和宽度。楼梯踏步宽300mm，高150mm是黄金比例，是比较适中的。但是对于公共建筑宽大于等于300mm，高100mm－150mm比较适中。住宅中楼梯段宽不能小于1100mm，楼梯平台宽度不能小于1100mm。楼梯梯段净宽不应小于1.10m。希望我的回答可以帮到你。

1、规范规定，高层建筑的“剪刀“楼梯,要在靠墙一侧要设置扶手。2、所谓剪刀梯就是上下层之间的楼梯中间设有拐弯，三层楼的楼梯之间像一把剪刀。18层以上的塔式高层建筑，两座疏散楼梯宜独立设置，当确有困难时，可设置剪刀楼梯。3、“剪刀楼梯”是连系建筑物楼层之间的通常形式之一。也可称之为叠合楼梯、交叉楼梯或套梯。它在同一楼梯间设置一对相互重叠，又互不相通的两个楼梯。在其楼梯间的梯段一般为单跑直梯段。剪刀楼梯最重要的特点是，在同一楼梯间里设置了两个楼梯，具有两条垂直方向疏散通道的功能。剪刀楼梯在平面设计中可利用较狭窄的空间，设置两部楼梯，这两部楼梯分属两个不同的防火分区，因而提高了建筑面积使用率。希望我的回答对你有帮助

剪刀梯的扶手安装没有要求，建议在靠墙一边做扶手这个剪刀梯，意思是说，两部楼梯套在一起，从侧面看起来，就像剪刀的两个刀口一样，设置剪刀梯的目的是在一类高层建筑里，有一层如果着火，能够让人流更快地疏散下去，所以建议靠墙一边做扶手

多层住宅(尤其要注意花园洋房)设有客梯，且客梯直接通至地下车库时，客梯在地下室不能直接开向楼梯间，应用乙级防火门和实体墙隔开。超过6层的住宅疏散楼梯间应通至屋顶。设有客梯的多层住宅、超过6层的多层住宅，当其疏散楼梯间为开敞楼梯间时，应注意其入户门是否乙级防火门。高层住宅设有“三合一”前室的剪刀楼梯间无论是否具备自然排烟条件都应设置正压送风系统。

你好，地下室封闭楼梯间的设计要求是：1楼梯间应能天然采光和自然通风，并宜靠外墙设置；2楼梯间内不应设置烧水间、可燃材料储藏室、垃圾道；3楼梯间内不应有影响疏散的凸出物或其它障碍物；4楼梯间内不应敷设甲、乙、丙类液体管道；5公共建筑的楼梯间内不应敷设可燃气体管道；6居住建筑的楼梯间内不应敷设可燃气体管道和设置可燃气体计量表。当住宅建筑必须设置时，应采用金属套管和设置切断气源的装置等保护措施。希望我的回答对你有所帮助！
