北京牡丹园公寓2号楼为1974年建的装配式框架结构,周边环境复杂,拆除时保留结构的安全以及噪声、粉尘控制是需首要考虑的问题。采用无损性切割技术将大部分构件拆除。详细介绍了施工部署、保留框架支撑、构件切割及变形观测方案。切割施工没有对原有结构造成明显损伤和变形,满足结构改造无损性拆除的要求。 Beijing Peony Garden Apartment Building 2 is an assembled frame structure built in 1974. The surrounding environment is complicated, the structure safety and noise and dust control during demolition are the primary issues to be considered. Most components are removed using a nondestructive cutting technique. Described in detail the construction and deployment, retaining the framework of support, component cutting and deformation observation program. Cutting construction did not cause obvious damage to the original structure and deformation, non-destructive structural reform to meet the requirements of demolition.
