摘要
在压杆理论的基础上,联系实际,对早拆体系进行了有限元分析,用图表的方式根据不同因素对支撑杆稳定性的影响进行说明。结果表明:标准层的梁板结构,早拆体系可满足施工安全要求;对于超大梁,宜在梁两侧与板相接的部位加设支撑;板的浇筑方向从中间向两侧浇筑有利于保证支撑杆的稳定性。
Based on compression bar theory,this paper analyzes early removing system by finite element software,introduces influencing factors of studdie stability by chart mode. The results show that early removing system can meet the requirement of construction safety for beam-slab structure of standard layer,the support is suitable used between beam and slab for super large beam,the stability of the support is ensured from the middle to both sides for pouring direction of the slab.
