摘　　要：在高层建筑施工中,上拉式悬挑脚手架的应用十分广泛,上拉式悬挑脚手架与梁的锚固尤为重要。为了探究混凝土梁中锚固件尺寸变化对锚固性能的影响,采用有限元软件ABAQUS建立并计算了24个锚固了不同尺寸锚固件的混凝土梁模型,探究了锚杆直径、锚杆长度、锚板宽度和厚度变化对极限承载力、极限滑移的影响。分析结果表明:锚固件的极限承载力受锚杆直径的影响较大,增大锚杆长度可以有效减小锚固件与混凝土之间的相对滑移,而锚板尺寸的改变对其锚固性能的影响较小,可为锚固件的设计和应用提供参考。In the construction of high-rise buildings,the application of pull-up suspended scaffold is very wide,and the anchorage of the pull-up suspended scaffold and beam is particularly important.In order to explore the influence of changes in the size of anchors on the anchoring performance of concrete beams,the finite element software ABAQUS was used to establish and calculate 24 concrete beam models with different sizes of anchors,and the influence of changes in bolt diameter,bolt length,anchor plate width and thickness on ultimate bearing capacity and ultimate slip was explored.The analysis results show that the ultimate bearing capacity of the anchor is greatly affected by the diameter of the anchor rod,and the relative slip between the anchor and the concrete can be effectively reduced by increasing the length of the anchor rod,while the change of the size of the anchor plate has litle influence on its anchoring performance,which can provide a reference for the design and applica-tion of the anchor.
