摘　　要：为确保整体钢平台模架竖向支撑装置搁置部位的安全可靠,对竖向支撑装置承重销搁置部位混凝土墙体的局部承压受力性能进行了深入研究。分析了承重销倾斜接触状态对混凝土墙体局部受压能力的影响,探讨了混凝土墙体增加间接钢筋和侧向预埋钢板对混凝土墙体倾斜局部承压承载力的提高效果,从而提出了提高混凝土结构局部抗压能力的有效措施。To ensure the safety and reliability located on vertical support device of integral steel platform formwork,the local bearing capacity of concrete wall with the bearing pin of vertical support device is deeply studied.The influence of the inclined contact state of the bearing pin on the local compression capacity of the concrete wall is analyzed,and the effect of adding indirect reinforcement and lateral embedded steel plate on the inclined local bearing capacity of concrete wall is discussed,and accordingly,the effective measures to improve the local compressive capacity of concrete structure are put forward.
