摘要
在立交桥、高架桥和人行天桥的建设过程中,作为施工模板支撑的脚手架搭设常遇到承载力不足,脚手架失稳等问题,根据现浇钢筋混凝土立交桥施工过程中此类脚手架的搭设情况,以实际工程中常用的WDJ碗扣式钢管脚手架为对象,运用有限元程序ANSYS进行分析,着重研究桥梁腹板位置变化、桥梁高度变化对脚手架受力的影响,同时对风荷载作用下的脚手架和隔梁位置下的脚手架进行受力分析,提出通常情况下WDJ碗扣式钢管脚手架的选用形式,为脚手架工程的安全施工提供一定的帮助。
During the construction of crossroad, problems are often confronted such as insufficient to the load bearing,offbalance of scaffold, etc. When trestle and pedestrain are used as the model of construction. According to this kind of building of scaffold in the process of the construction of overpasses, this article makes WDJ scaffold used in the practical construction the target, and analyzes it through ANSYS. The article primarily studies the position change of the bridge on sternum and the effect caused by the change of the altitude of bridge on the force of scaffold. And also it analyzes the force of scaffold under the load of wind and that under this location of the baffle plate. It puts forward the choices of WDJ scaffold in the usual circumstances, which provides help to the safe construction of the scaffold.
