摘  要:针对我国单层工业厂房设计主要采用装配式钢筋混凝土结构体系,其基本柱距是6m.应用柱下预留杯口钢筋混凝土条型基础,相应的结构构件如柱、吊车梁、联系梁、屋面板、横向墙板等均以配套成型,便于构件工厂预制和安装,现场施工速度快,节省工程投资,符合节约能源,环境保护的要求,具有广泛的应用前景.通过工程实例分析,充分利用力学原理,将基础杯口处上部受压区钢筋可断开、下部受拉钢筋贯通的特点,提出柱下预留杯口钢筋混凝土条型基础设计思路和要点,以使工程技术人员借鉴.In our country, the design of single-deck industrial factory principally adopt fabricated reinforced concrete structure, and the basic column space is 6m. Apply of under Column Preformed Hole Reinforced Concrete Strip Foundation, Corresponding structural elements such as column, crane beam, link beam, roof board and transverse wall panel all are form a complete set. This structure can prefabricate expediently by component factory, install conveniently, construct quickly, save construction investment, and meet the request of energy-saving and environmental protection,which has wide future prospects of application and extension.By the project example, this paper makes full use of mechanics principle, analyzes the trait that reinforced pressure zone can be disconnected and reinforced by pulling through, and puts forward the design points of under column preformed hole reinforced concrete strip foundation to provide ideas to engineers and technicians.
