落地式空中造楼机自动开合模体系研发与应用

Development and Application of Automatic Opening and Closing Formwork System of Ground-supported Aerial Building Machine

落地式空中造楼机是用于高层住宅现浇钢筋混凝土施工的成套机械装备。自动开合模体系是空中造楼机的核心设备,由吊挂在造楼机顶部钢平台底面并与剪力墙分布一致的内、外模板组成,可在建造过程中实现模板自动定位、自动开合等功能。对应用于落地式空中造楼机的新型模板体系构造、模板定位与固定工法、混凝土浇筑工艺等进行研究。示范工程实践表明,该新型模板体系可实现模板自动开合、自动定位运行;开模后的混凝土表面光滑、色泽均匀,达到清水混凝土效果。

The ground-supported aerial building machine is a complete set of mechanical equipment for cast-in-situ reinforced concrete construction of tall residential buildings.The automatic opening and closing formwork is the core equipment of the aerial building machine,which is composed of internal and external formworks hanging at the bottom of the steel platform at the top of the building machine and consistent with the distribution of the shear wall.It can realize the functions of automatic positioning and automatic opening and closing formwork in the construction process.This paper studied the construction of new formwork system,formwork positioning and fixing method,and concrete pouring technology for the ground-supported aerial building machine.The demonstration project practice shows that the new system can realize the automatic opening and closing formwork and the automatic positioning operation.The concrete surface after opening formwork is smooth and the color is uniform,reaching the effect of fair-faced concrete.
