2、当两端固接时，跨中及支座弯矩均取：M中。2.5 强度计算时，砼等级C25是1.5倍后，可按C35先求出钢筋面积As1,然后再除以1.35后作为最终As进行配筋，即：As=As1/1.35；当采用HRB400钢时：As=As1/1.203绘图3.1 比例：平剖面图150； 构件详图1253.2 平剖面图设计深度：平面图应表示构件布置、编号、关系尺寸（分尺寸、总尺寸）、轴线号、各平面标高，梯板走向（上、下）、板配筋等；剖面图应表示构件布置、编号、关系尺寸（分尺寸、总尺寸）轴线、板厚、可见梯柱等；被切断面应填充。图纸说明中应注明：楼梯应配合结施01（结构设计总说明）及03G101-2（XT钢筋构造）

3、进行施工；吊挂柱纵筋上端（在楼层梁内）保护层厚度为50mm；楼梯节点详图见建施。3.3 构件详图：梯板以03G101-2的平面注写方式表示。平台板表示方法同楼层板；注明平台板编号、板厚、配筋规格。梯梁以截面或平面注写方式表示：注明梁模板尺寸及底筋、面筋、箍筋规格（梯梁与柱、混凝土墙相接时按框架梁构造）。梯柱以截面注写方式表示：注明截面尺寸、高度范围、钢筋规格等，吊挂柱还应绘出纵筋图。梯板基础：梯板第一跑下方除布置为梯梁外，其节点应索引见03G101-2第49页，且当采用砌体或其它类型的基础时，应在施工图中将基础表示清楚。梯板设计选用一览表附表1序号构件编号基本尺寸永久荷载（KN/m2）活荷载（
