一种四边不出筋可密拼施工的桁架叠合楼板及其制备方法

本发明涉及一种四边不出筋可密拼施工的桁架叠合楼板及其制备方法，桁架叠合楼板包括四边不出筋且四周边缘为平直端面的预制混凝土底板以及沿其板边靠边布置的桁架；桁架由上弦杆和连续弯折的腹杆组成，腹杆下端直接锚入底板混凝土内且锚固深度不小于25mm，由混凝土和内部钢筋网片构成的底板充当桁架下弦组件参与受力；相邻底板密拼、拼缝小于20mm，通过垂直拼缝并穿过拼缝两侧板边桁架的附加拼缝搭接钢筋实现连接。制备时采用普通平面模台，依次进行钢筋桁架布置、混凝土浇筑及养护脱模；施工时依次进行吊装就位、密拼安装、附加钢筋布设、后浇叠合层浇筑及养护。本发明节省钢材、减轻底板自重、模具通用、施工便捷、拼缝连接可靠。
