我想问一个楼梯问题
楼梯间2.75×4.5米进深,层高4.2米,楼梯下有个过道,多少踏步合适我想问一个楼梯问题,楼梯间2.75×4.5米进深,层高4.2米,楼梯下有个过道,多少踏步合适.层高36米宿舍楼梯踏步需要设置多少个楼梯踏步级数的算法是什么问一问大家楼梯踏步级数怎么算请问楼梯单数双数讲的是级数还是踏步楼梯设计开间3、2米进深3.3米层高4米请问怎样设计楼梯间层高3米,宽2.47米,深2.2米左右,问一下是做旋转弧梯好还是折梯好看还有是要做有竖面封板的好看,还是用镂空的好看那材质想釆用铸钢作基底,踏步用实木,扶手也用木质漆白的层高2.70,长2.50,宽1.80,做成U型楼梯,该有多少踏步我想做一楼到二楼的楼梯,宽是1.35米 ,进深长是2米,层高是2.9米,楼梯下想做卫生间,谢谢木质楼梯踏步的设置有哪些讲究对于一个层高3.0米,进深6.0米,进深2.7米的一个三层民用住宅设计双跑的楼梯的剖面图和平面图一层设计成不等跑的应如何设计啊请问楼梯的进深怎么计算如何确定楼梯开间的进深请给说下楼梯级数怎么算

展开全部1、计算切割角tan22.5°=a/300、a=300*0.414=124.264,2a=248.5。45° 就是一个切割角即可。2、电缆桥架分为槽式、托盘式和梯架式、网格式等结构,由支架、托臂和安装附件等组成。可以独立架设, 也可以附设在各种建(构)筑物和管廊支架上,体现结构简单、造型美观、配置灵活和维修方便等特点,全部零件均需进行镀锌处理,安装在建筑物外露天的桥架,如果是在邻近海边或属于腐蚀区,则材质必须具有防腐、耐潮气、附着力好, 耐冲击强度高的物性特点。已赞过已踩过你对这个回答的评价是?评论
收起槽式桥架的价格因品牌、规格、材质、制造工艺等因素而异。一般来说,普通的槽式桥架价格在20-80元/米之间,而防火槽式桥架的价格则要更高一些,一般在100-200元/米之间。建议在购买槽式桥架时,根据自己的实际需求和预算进行选择,同时也可以参...
