螺纹段钢筋连接处补强技术在桥梁工程中的应用研究

The Application Study on Reinforcement Technology of Thread Steel Bar Joint in the Bridge Engineering

通过室内试验和有限元模拟的方式对在桥梁工程中应用的螺纹段钢筋连接处补强技术进行了介绍,对相应的补强方法进行了研究,并对室内试验结果进行了分析,结果证明采用双套筒连接可以有效解决钢筋笼不对中及强度等问题,加强了钢筋笼连接后的强度,加快了施工进度,具有较大的工程应用价值。

By means of indoor test and the finite element simulation, this paper introduced the reinforcement technology of thread steel bar joint in the bridge engineering.It also studied the corresponding reinforcement method and analyzed the indoor experiment results.The results showed that the double sleeve connection could effectively solve the problems, such as misalignment and strength of the reinforcement cage,strengthened the strength of reinforcement cage and accelerated the construction progress, which had great engineering application value.
