Suspended printing reinforced concrete bridge, construction device and printing method
The invention relates to a suspended printing reinforced concrete bridge, a construction device and a printing method. The bridge comprises a pier, a variable cross-section beam, a bridge deck slab and longitudinal and transverse steel bars. The bridge pier is firstly printed, and then the variable cross-section beam and the bridge deck are printed. The variable cross-section beam is printed layer by layer from bottom to top, the upper layer is suspended and lengthened layer by layer compared with the lower layer, and longitudinal and transverse reinforcements are laid between layers. The construction device comprises a rail system, a frame system, a formwork system and a printing system, the frame system provides a working platform for the formwork system and the printing system, the formwork system adopts a suspended formwork to provide support for suspended printing of the variable cross-section beam, the printing system adopts a manipulator to install steel bars, and an extrusion head is adopted to extrude and stack and print concrete. According to the variable cross-section beam bridge, direct layered printing can be achieved, suspended printing of reinforced concrete is achieved through the suspended formwork system, the working procedure is simple, and the variable cross-section beam bridge is suitable for site construction.
本发明是一种悬空打印钢筋混凝土桥梁及施工装置、打印方法，桥梁包括桥墩、变截面梁、桥面板和纵横向钢筋。桥梁先打印桥墩，后打印变截面梁和桥面板。变截面梁由下而上分层打印，上层比下层逐层悬空增长，层间铺设纵横向钢筋。施工装置包括轨道系统、框架系统、模板系统和打印系统，框架系统为模板系统和打印系统提供作业平台，模板系统采用吊模为变截面梁的悬空打印提供支撑，打印系统采用机械手安装钢筋，采用挤出头挤出并堆叠打印混凝土。本发明提供了一种可直接分层打印的变截面梁式桥，且采用吊模系统实现了钢筋混凝土悬空打印，工序简单，适合现场施工。
