随着混凝土构件加固技术的发展,桥梁加固用的胶粘剂的应用越来越广泛。在改进加固质量、节省工时与能耗、提高施工速度、美化建筑物等方面具有重要的意义。由于粘钢加固钢筋混凝土梁构件有很多的优点,目前对粘钢胶的要求越来越高,做者在国外研究的基础上,通过加入3种辅助剂来提高和改善胶体的性能,使钢-钢拉伸抗剪强度得到了明显的提高。
With the development of concrete components reinforcement technology, the application of bridge reinforcement adhesive is more and more widely. It is of great significance to improve the quality of reinforcement, save man-hours and energy consumption, speed up construction and beautify buildings. Due to the many advantages of sticking steel reinforced concrete beam members, the current requirements for sticky steel glue are getting higher and higher. Based on foreign studies, the author improves and improves the performance of colloids by adding three kinds of auxiliary agents, - Steel tensile shear strength has been significantly improved.
