贝雷架作为桥梁承重支架应用时的支点设置方法及加固研究

尽管贝雷架在现浇桥梁结构中得到了广泛应用,但由于贝雷支架支撑点设置不当引起的事故却时有发生.针对这种情况,该文首先从理论角度出发分析了支点设置于竖杆处的必然性,然后指出了几种常用的支点设置方法,并分析了这些设置方式的利弊和应用条件,最后结合实例讨论了支点设置方式对贝雷架力学状态的影响,并提出了合适的加固处理方案.实践证...

Study on Support Setup Method and Reinforcement of Beilei Frame Taken for Application of Bridge Load-bearing Bracket

The Beilei frame is widely applied in the cast-in-situ bridge structure,but the accidents occur sometimes caused by the improper support setup of Beilei frame.In the light of this condition,the article firstly analyzes the necessity of the support to set up at the vertical rod from the theoretical angle,then points out several common support setup methods and analyzes the advantages and disadvantages of these setup modes and the application conditions,and finally discusses the influence of the support setup mode on the mechanics status of Beilei frame according to the cases and puts forward the suitable reinforcement handling scheme.The practices prove that this handling method is feasible and has some guiding significances for the future construction.
