Introduction of 11G101-2

11G101-2《混凝土结构施工图平面整体表示方法制图规则和构造详图（现浇混凝土板式楼梯）》是对03G101-2《混凝土结构施工图平面整体表示方法制图规则和构造详图（现浇混凝土板式楼梯）》的修编。
本次修编按新规范对图集中标准构造详图部分进行了修订；结合设计人员习惯对制图规则部分增加了剖面注写和列表注写两种方式。
本图集适用于非抗震及抗震设防烈度为6～9度地区的现浇钢筋混凝土板式楼梯。
图集中现浇混凝土板式楼梯包括11种类型，其中AT～HT用于非抗震设计及不参与主体结构抗震设计的楼梯，ATa、ATb用于采取滑动措施减轻楼梯对主体（框架）影响的楼梯，ATc用于框架中参与主体结构抗震设计的楼梯。
