下面参考图1-图6描述根据本发明实施例的一种新型装配式钢-再生混凝土混合框架结构体系100。
如图1-图6所示，根据本发明实施例的一种新型装配式钢-再生混凝土混合框架结构 体系100包括多个框架柱10、多个组合楼板20和多个梁柱节点30。
具体地，每个框架柱10沿着竖直方向延伸，多个框架柱10在横向方向上呈多排布置，并且在纵向方向上呈多列式排布，组合楼板20支撑在框架柱10上。
进一步地，组合楼板20包括框架梁21和板体22，多个框架梁21在竖直方向上分布在多个不同的水平面内，在同一水平面内分布的多个框架梁21中的每一个沿横向或纵向延伸，每个框架梁21的两端分别与相邻的两个框架柱10相连；板体22包括压型钢板221、再生混凝土层222、普通混凝土层223、剪力连接件224及钢筋225。
